DETAILED DESCRIPTION

[0060] The order of the steps in the disclosed processes may be altered within the scope of the invention.

[0061] In conjunction with the accompanying drawings, the following detailed description provides a more specific and detailed explanation of various embodiments of the apparatus and method for removing fluids. These embodiments are provided to illustrate the invention but should not be seen as limiting its scope; the apparatus and method can be embodied in many different forms and is intended to be thorough and comprehensive to those skilled in the art.

[0062] For the purposes of promoting an understanding of the principles of a passive siphon-based apparatus for removing fluids, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same, only as examples and not intended to be limiting.

[0063] Various terms, recognized by those skilled in the art are used herein but not to be limiting.

[0064] The apparatus for removing fluids on boats may be suitable for use on a wide variety of watercraft. This may include, but is not limited to, boats that can plane. Examples of such boats may include bowriders, runabouts, flats boats, and sport fishing boats. The apparatus may also be suitable for use on personal watercraft, such as jet skis and wave runners. It is important to note that this list is not exhaustive, and the apparatus may be adaptable to other types of boats and watercraft not specifically mentioned here. The versatility of the apparatus may allow it to be used on various boat designs and sizes, potentially making it a useful addition to many different types of marine vessels.

[0065] In some uses, the apparatus may provide a novel solution for maintaining a dry bilge without relying on electrical power or frequent manual intervention. The apparatus may utilize natural forces generated by the boat's movement through water to create a vacuum effect, which may then be used to extract fluid from the bilge area.

[0066] In some cases, the apparatus may offer several advantages over traditional bilge pump systems. The apparatus may operate continuously while the boat is in motion, potentially reducing the risk of fluid accumulation. Additionally, the apparatus may function without electrical power, which may enhance reliability and reduce the risk of system failure due to electrical issues.

[0067] The apparatus may require minimal maintenance, potentially reducing the need for frequent checks or repairs. This low-maintenance characteristic may be particularly beneficial for boat owners who may not have the time or expertise to regularly service complex bilge systems.

[0068] In some cases, the apparatus may be designed to integrate seamlessly with existing boat structures, potentially allowing for easy installation in a wide range of watercraft. The system may be adaptable to various boat sizes and types, from small personal watercraft to larger vessels.

[0069] In its most basic form, a passive siphon-based apparatus for removing fluids, may have the following components and steps: (1) a bilge accumulator 001, (2) a tube 002, (3) a siphon generator 003.

[0070] These components and steps, generally speaking, are configured as follows: (1) a bilge accumulator 001; (2) the bilge accumulator 001 has a body 004 with a bottom opening to allow fluid intake; (3) an inlet fluid receiver 005 resides in the body 004; (4) A bilge accumulator mounting bracket 011 is positioned to hold the body 004 in place and secured by an accumulator hold down 012; (4) a port 007 on the top of body 004 is connected to a tube 002; (5) the tube 002 is connected to a port 007 on top of the siphon generator 003; (6) the siphon generator 003 may have a mounting bracket 008; (7) a suction hole 009 is on the bottom of the siphon generator 003.

[0071] When the apparatus is used on a boat, these components and steps, generally speaking, may be configured as follows: (1) a bilge accumulator 001 is inside the bilge of the boat; (2) the bilge accumulator brackets 011 are mounted to the boat and the body 004 is positioned between the brackets 011; (3) an accumulator hold down 012 is turned perpendicular to each of the mounting brackets 011 to hold the body 004 in place; (5) a port 007 on the top of body 004 is connected to a tube 002; (6) the tube 002 travels upwardly along the inside of the transom and through a hole in the transom or over the top of the transom, or by some other means to the outside of the boat and then downwardly; (7) the tube 002 is connected to a port 007 on top of the siphon generator 003; (7) the siphon generator 003 is connected to the outside of the boat with a mounting bracket 008; (8) the siphon generator 003 can be aligned to the bottom of the boat with a running surface locator 013 and a running surface ramp 015 creates a smooth flow rearward toward the outer edge of the siphon generator 003; (9) a suction hole 009 may be below the service bottom of the boat located in the venturi siphon 014 of the siphon generator 003.

[0072] The apparatus utilizes a combination of a bilge accumulator 001, a connecting tube 002, and a siphon generator 003. The siphon generator 003 creates a vacuum that draws fluid from the bilge accumulator 001 through the tube 002 and then discharges the fluid through the suction hole 009 of the siphon generator 003.

[0073] When used on a boat, an apparatus may have a bilge accumulator 001 mounted in the bilge of the boat. The bilge accumulator 001 may have a filter 006, or sponge, and absorbs any excess fluid not removed by the bilge pump.

[0074] a passive siphon-based apparatus for removing fluids may also have one or more of the following: (1) a bilge accumulator 001 that is a hemispherical shape with a sponge inserted into it; (2) a dual siphon siphon generators 003 on the external side of the boat; (3) siphon generators 003 with varying convex shapes to change the properties of the Venturi effect; (4) a check valve 010 located above the bilge accumulator 001 in the tube 002 to ensure no water flows into the boat when at rest or when the speed of the boat is not high enough to pull a vacuum through the siphon generator 003; (5) a filter 006 in the tube 002.

[0075] When used on a boat, the bilge accumulator 001 is strategically positioned in the bilge area of the boat, which is the lowest part of the hull where fluid naturally collects. The bilge accumulator gathers excess fluid from this area. Connected to the bilge accumulator 001 is a tube 002 that facilitates the movement of fluid from the bilge accumulator 001 to the siphon generator 003. The siphon generator 003 is mounted on the exterior of the boat at the water line, creating a vacuum that draws fluid through the tube 002 from the bilge accumulator 001.

[0076] As fluid collects in the bilge, it enters the bilge accumulator 001 through a bottom opening in the body 004 designed for fluid intake. Inside the body 004 of the bilge accumulator 001, a sponge or other filtering device like a screen or mesh, may be used to help facilitate fluid, free of debris and particulates, pass through. This filtering mechanism may prevent clogs, and may ensure that the fluid drawn through the tube 002 to the siphon generator 003 is clean.

[0077] The apparatus may have a bilge accumulator 001 that is hemispherical in shape to collect fluid from the bilge area. Additionally, the bilge accumulator 001 may use a sponge as a filter which assists in the collection and priming of fluid. The sponge may act as an initial filter, capturing larger debris and facilitating the priming process by retaining fluid, helping the siphon generator 003 maintain continuous suction.

[0078] On a boat, a siphon generator 003 may be mounted to the external transom of the boat, below the service bottom of the boat. The siphon generator 003 allows the fluid to rush by an orifice, suction hole 009, that in turn creates a vacuum which then pulls fluid from the bilge accumulator 001.

[0079] The siphon generator 003 may have a convex shape to enhance the Venturi effect. This aerodynamic shape increases the velocity of the fluid flowing past the generator, thereby creating a vacuum. The vacuum created by this effect may enable the siphon generator 003 to draw fluid from the bilge accumulator 001 through the connected tube 002.

[0080] In some embodiments, the apparatus is designed to accommodate variable vessel motion, including intermittent planing or wave surges. When water flow across the siphon generator 003 is temporarily disrupted, the Venturi effect may cease, and siphoning may pause. However, due to the design of the bilge accumulator 001 and the presence of a check valve 010 positioned in the tube 002, fluid within the system remains sealed, reducing the likelihood of air intrusion.

[0081] This configuration enables the system to resume siphoning automatically once sufficient water flow returns, without requiring manual re-priming.

[0082] At initial installation or after prolonged inactivity, the bilge accumulator 001 may retain a small volume of fluidparticularly when equipped with a sponge or similar filter 006. The retained fluid assists in establishing a fluid column in the tube 002, enabling the siphon generator 003 to initiate vacuum formation more quickly upon vessel motion. In some designs, the geometry and material properties of the accumulator facilitate capillary retention and minimize evaporation, allowing the system to remain primed even after dry periods or storage.

[0083] The apparatus may be unique when compared with other known systems and methods because it provides: (1) for use when no electrical source is available; (2) operates in a hands-off manner anytime the boat is on plane; (3) works with boats of various lengths and performance capabilities.

[0084] The apparatus may be unique in that it is structurally different from other known system and methods due to the presence of (1) a bilge accumulator 001 that will pull excess fluid below the typical float switch level; (2) has a flexible tubing or a rigid tube 002 for installation and clean hull pass through; (3) a siphon generator 003 on the outside of the boat to create a vacuum to pull water from inside the boat.

[0085] The dimensions of the bilge accumulator 001 may vary depending on the specific application. In some cases, the bilge accumulator 001 may have a length and width between 2.54 cm to 15.24 cm (1.0 inch to 6.0 inches), and a height of 1.27 cm to 7.62 cm (0.5 inches to 3.0 inches). These dimensions may allow the bilge accumulator 001 to fit in various bilge configurations while providing sufficient capacity for fluid collection.

[0086] The bilge accumulator 001 and the siphon generator 003 may be made of, but not limited to, plastic, stainless steel, aluminum, starboard, or another material that will stand the elements of salt and fresh fluid corrosion. The choice of material may depend on factors such as the expected operating environment, manufacturing considerations, and cost.

[0087] The bilge accumulator 001 may be of a shape, but not limited to, square, rectangular, triangular, oval, eliptical, circular.

[0088] In some embodiments, the bilge accumulator 001 may be designed in various shapes beyond hemispherical, such as cylindrical, conical, or cuboid. A cylindrical shape, for instance, may provide more vertical coverage in deeper bilges, while a conical shape could help funnel fluid more efficiently to the outlet port 007. A cuboid shape might be better suited for boats with more angular bilge spaces.

[0089] The apparatus may have a bilge accumulator 001 that is hemispherical to allow a sponge to be placed into the bilge accumulator 001.

[0090] The bilge accumulator 001 may have a filter 006 such as a screen, filter, or sponge.

[0091] The bilge accumulator 001 may have mounting brackets that attach to the boat. The mounting brackets may use a securing device, like tabs with screws, that allow the bilge accumulator 001 to be removed from the boat so a sponge can be replaced. In some embodiments, the bilge accumulator 001 may be removably secured within the mounting brackets 011 using clips, tabs, or tool-free locking mechanisms. This configuration allows the user to easily remove the body 004 to inspect, clean, or replace internal components such as the sponge or filter 006. Such access facilitates routine maintenance and supports sustained performance of the fluid removal system in marine environments.

[0092] The bilge accumulator 001 may have teeth on the sides to help keep the sponge clear of large debris.

[0093] The bilge accumulator 001 may or may not have a sponge. An advantage of using a sponge is the fluid in the bilge primes the bilge accumulator 001 and allows the device and system to draw fluid toward the bilge accumulator 001.

[0094] The tube 002 may have an inner diameter between 6.35 mm to 50.8 mm (0.25 inches to 2.0 inches). This range of diameters may allow for efficient fluid flow while accommodating various installation requirements and fluid volumes.

[0095] The tube 002 may be made of, but not limited to, plastic, vinyl, stainless steel, aluminum, or another material that will stand the elements of salt and fresh fluid corrosion.

[0096] The tube 002 may be made rigid whereas in some versions of the apparatus the tube 002 may be flexible.

[0097] The tube 002 may be a single tube 002 or multiple tubes 002 connected via couplings.

[0098] Furthermore, the tube 002 may be a single, continuous piece, providing a direct path for fluid transport from the bilge accumulator to the siphon generator.

[0099] Alternatively, the tube 002 may comprise multiple sections connected via couplings. This modular design may allow for easier installation or replacement of tube sections, as well as the possibility of extending or shortening the tube length to fit different boat sizes or configurations.

[0100] A check valve 010 may be incorporated into the tube 002 system, positioned between the bilge accumulator 001 and the siphon generator 003. This would prevent backflow of water into the bilge when the boat is stationary.

[0101] The siphon generator 003 may be of a shape, but not limited to, square, rectangular, triangular, oval, eliptical, circular.

[0102] The siphon generator 003 may have dimensions, but not limited to, a length between 2.54 cm to 15.24 cm (1.0 inch to 6.0 inches), a width between 2.54 cm to 15.24 cm (1.0 inch to 6.0 inches), and a height of 1.27 cm to 7.62 cm (0.5 inches to 3.0 inches).

[0103] The siphon generator 003 may vary in shape from a flat plane to mount flush against the transom or may have an L-shapeto extend beyond the transom into the water.

[0104] The siphon generator 003 may have a tab wing to facilitate locating the siphon generator 003 on a boat hull.

[0105] The siphon generator 003 may have one or more ports and suction holes to support multiple bilge accumulators.

[0106] In some embodiments, the apparatus may be subject to potential failure modes during prolonged use or adverse environmental conditions. These may include clogging of the inlet fluid receiver 005 or filter 006 due to debris accumulation, blockage of the tube 002, loss of suction due to air intrusion, or misalignment of the siphon generator 003 relative to the hull's running surface. Such conditions may reduce or interrupt fluid removal, compromising system performance.

[0107] To address these challenges, the system may incorporate design adaptations such as multi-stage or self-cleaning filtration assemblies within the bilge accumulator 001, flexible tubing with smooth interior surfaces to reduce blockage, and use of anti-kink couplings. The siphon generator 003 may feature a convex profile and strategically placed suction hole 009 to minimize debris adhesion and optimize flow. Alignment aids such as running surface locator 013 and an adjustable mounting bracket 008 may ensure proper placement relative to the hull, maximizing the Venturi effect and reducing the likelihood of siphon failure due to misalignment or cavitation.

[0108] In some cases, the filter 006 in the bilge accumulator 001 could be designed as a multi-stage filtration system. This could involve a coarse initial filter to catch larger debris, followed by progressively finer filters to remove smaller particles. This would enhance the system's ability to handle various types of contaminants and reduce the risk of clogging.

[0109] In some aspects, the siphon generator 003 could be designed with an adjustable mounting bracket 008, allowing for fine-tuning of its position relative to the water line. This would enable optimization of the Venturi effect for different boat speeds and water conditions, potentially improving efficiency across a wider range of operating scenarios.

[0110] FIG. 1 illustrates a perspective view of, FIG. 2 a side view, FIG. 3 a top down view, and FIG. 4 a bottom view of a passive siphon-based apparatus for removing fluids, according to aspects of the present disclosure. a passive siphon-based apparatus for removing fluids may include a bilge accumulator 001, a tube 002, and a siphon generator 003. The bilge accumulator 001 may have a body 004 with an inlet fluid receiver 005. The inlet fluid receiver 005 may allow fluid to enter the bilge accumulator 001. A filter may be positioned within the body 004 to prevent debris from entering the system. The bilge accumulator 001 may be secured to the boat using a bilge accumulator mounting bracket 011. An accumulator hold down 012 may be used in conjunction with the mounting bracket 011 to ensure the bilge accumulator 001 remains in place. A port 007 may be located on the top of the bilge accumulator 001. A tube 002 may be connected to this port 007, providing a pathway for fluid to flow from the bilge accumulator 001 to the siphon generator 003. A check valve 010 may be incorporated into the tube 002 system. The check valve 010 may prevent backflow of water into the bilge when the boat is stationary or when the siphon effect is not active. The siphon generator 003 may be mounted on the exterior of the boat, typically near the waterline. A running surface locator 013 may be used to properly position the siphon generator 003 relative to the boat's hull. The siphon generator 003 may include a venturi siphon 014, which creates a vacuum effect to draw fluid through the system. A running surface ramp 015 may be incorporated into the design of the siphon generator 003. This ramp 015 may help create a smooth flow of water over the siphon generator 003, enhancing its efficiency.

[0111] In operation, fluid may enter the bilge accumulator 001 through the inlet fluid receiver 005 into the body and is drawn into the tube 002 via the port 007. The fluid may travel through the tube 002, potentially passing through the check valve 010, and a filter 006 before reaching the siphon generator 003. At the siphon generator 003, the venturi siphon 014 may create a vacuum effect, drawing the fluid out of the boat and into the surrounding water.

[0112] FIG. 5 is a perspective view, FIG. 7 is a side view of the same, and each illustrates an embodiment of the apparatus installed on a typical boat where the bilge accumulator 001 is shown inside the boat and the tube passes through the hull, generally in the transom, to the siphon generator 003 below the waterline at rest.

[0113] FIG. 6 is a perspective view of an embodiment of the apparatus, similar to FIG. 5 and FIG. 7, installed on a typical boat where the bilge accumulator 001 is shown inside the boat but in this embodiment the tube passes over the transom and down the aft side of the hull, to the siphon generator 003 below the waterline at rest.

[0114] FIG. 8 is a perspective view from the underside of a bilge accumulator 001 body 004. In the embodiment the inlet fluid receiver 005 can be seen. The underside of the bilge accumulator body 001 features a series of regularly spaced, block-like projections extending downward from the body surface 004. These projections are shaped with vertical walls and flat upper surfaces, resembling crenellations or castellations commonly seen in masonry battlements. This structural pattern may enhance fluid flow characteristics by reducing surface contact with the bilge floor, thereby facilitating drainage and minimizing clogging. Additionally, the protrusions may serve to elevate the body 004 above debris or sediment that accumulates at the lowest point of the bilge.

[0115] In some embodiments, these downward projections may also provide passive structural support or interlocking stability with other components or surfaces within the bilge compartment.

[0116] FIG. 9 is a perspective view of the plurality, two, bilge accumulator mounting brackets 011.

[0117] FIG. 10 is a perspective view of the accumulator hold down 012.

[0118] FIG. 11 is a perspective view of the exploded components of the bilge accumulator 001. A body 004 is show between two bilge accumulator mounting brackets 011. Each bilge accumulator mounting brackets 011 would be mounted to the boat in the bilge area in such a way as to allow a body 004 to fit snugly between the bilge accumulator mounting brackets 011 and so fluid could pass into the body 004. The method of mounting the accumulator mounting brackets 011 is typically done with a fastening means such as a screw. However, an adhesive could be used. In some instances, a manufacturer could build the accumulator mounting brackets 011 into the fiberglass mold so the accumulator mounting brackets 011 would be an integral part of the boat. After a body 004 is positioned between the accumulator mounting brackets 011 an accumulator hold down 012 is placed on the accumulator mounting bracket 011 and turned perpendicular to hold a body 004 in place. In some embodiments, the self-locking mechanism may include a spring-loaded tab, a quarter-turn latch, a cam-style lever, or a snap-in clip that secures the accumulator hold down 012 to the mounting bracket 011 without the need for separate fasteners. These mechanisms allow the user to quickly engage or release the hold down for maintenance, such as sponge or filter replacement, while maintaining a secure fit during vessel operation. In some versions the accumulator hold down may be of the type that has a self locking mechanism and remains attached to the accumulator mounting bracket 011.

[0119] FIG. 12 illustrates a perspective view of a siphon generator assembly, according to aspects of the present disclosure. FIG. 13 depicts an underside view of the siphon generator assembly of FIG. 12, and FIG. 14 shows a side view of the siphon generator assembly. The siphon generator 003 may include a port 007, as shown in FIG. 12 and FIG. 14. The port 007 may serve as a connection point for the tube that links the siphon generator 003 to the bilge accumulator. This connection may allow fluid to flow from the bilge accumulator to the siphon generator 003. A mounting bracket 008 may be attached to the siphon generator 003, as illustrated in FIG. 12 and FIG. 14. The mounting bracket 008 may be used to secure the siphon generator 003 to the exterior of the boat. In some cases, the mounting bracket 008 may be adjustable, allowing for fine-tuning of the siphon generator's 003 position relative to the water line. This adjustability may enable optimization of the siphoning effect for different boat speeds and water conditions. The running surface locator 013, visible in FIG. 12 and FIG. 14, may help align the siphon generator 003 with the bottom of the boat. This alignment may be crucial for optimal performance of the siphoning system. A running surface ramp 015 may be incorporated into the design of the siphon generator 003, as shown in FIG. 12, FIG. 13, and FIG. 14. The running surface ramp 015 may create a smooth flow rearward toward the outer edge of the siphon generator 003, potentially enhancing the efficiency of the siphoning effect.

[0120] FIG. 13 shows a cross-sectional view of the siphon generator 003, revealing a suction hole 009 positioned on the underside of the siphon generator 003. The suction hole 009 serves as the outlet through which bilge fluid is expelled from the system. A Venturi siphon 014 is incorporated into the siphon generator 003 and is configured to generate a vacuum as external water flows across the underside of the siphon generator 003 during vessel movement. This flow accelerates through the Venturi siphon 014, producing a localized low-pressure zone at the suction hole 009 that draws fluid from the bilge accumulator through a connected tube and discharges it overboard. The underside of the siphon generator 003 may be contoured to streamline the water flow across the suction hole 009 and reduce turbulence, thereby enhancing vacuum efficiency and minimizing clogging or cavitation.

[0121] In some aspects, the apparatus for removing fluid from boats may be produced individually, in batches, or via a continuous assembly process. The choice of production method may depend on various factors such as the scale of production, the specific requirements of the boat, and the resources available. For instance, individual production may be suitable for custom-made boats or small-scale operations, while batch or continuous assembly may be more efficient for larger-scale production or standard boat models. Regardless of the production method, each component of the apparatus, including the bilge accumulator, the tube, and the siphon generator, may be carefully crafted and assembled to ensure optimal performance and durability. The materials used for these components, such as plastic, vinyl, stainless steel, or aluminum, may be selected for their ability to resist corrosion from salt and fresh water, further enhancing the longevity and reliability of the apparatus.

[0122] For instance, to create one possible version of an apparatus as described herein, first gather all the mentioned components. Assemble the components in a logical order, following the practices of a skilled person in the field.

[0123] Confirm the availability of materials. Fabricate the bilge accumulator 001 by cutting the material to the appropriate size. Drill a hole in the middle of the body 004. Insert a coupling as the inlet port 007. Connect a sponge and secure it to the body 004.

[0124] Fabricate the siphon generator 003 by cutting the material to the appropriate size. Connect a second piece of material at a 90 degree angle, or instead attach 90 degree angle brackets that will be used to mount the siphon generator 003 to the boat. Drill a hole offset from the center of the siphon generator 003. Carve out a concave section relative to the hole. Insert a coupling in the hole.

[0125] The tube 002 will be connected to the inlet port 007 coupling on the bilge accumulator 001 and to the outlet port 007 coupling on the siphon generator 003.

[0126] A method of using an apparatus for removing fluid can be described in some versions by first selecting an appropriate boat for installation. Identify a location at an optimal point on the transom to drill a hole. The transom hole should be approximately 10 inches above the fluid line or at a height that is appropriate for the particular boat. Insert a hull pass through into the transom. Mount the bilge accumulator 001 in the bilge. Mount the siphon generator 003 to the outside of the boat approximately at the running service, or very bottom, of the hull. Run the tubing from the bilge accumulator 001 up the transom and through the hull pass through and down the transom to the siphon generator 003. Insert the tubing on the inlet and outlet port 007 couplings and secure with hose clamps as needed.

[0127] An apparatus may use rigid tubing in place of flexible tubing. The operation of the apparatus will be the same but the install process may require one or more pieces of tubing.

[0128] In some cases, the method for using the apparatus to remove fluid from a boat's bilge may involve a series of steps. Initially, the bilge accumulator may be positioned in the bilge of the boat. This location is typically the lowest part of the boat's hull where fluid naturally collects.

[0129] The bilge accumulator, which may have a body with a bottom opening for fluid intake, is designed to collect this excess fluid.

[0130] Once the bilge accumulator is in place, a tube may be connected to it. This tube serves as a conduit for the fluid, facilitating its movement from the bilge accumulator to the siphon generator. The tube may be made of a material that is resistant to corrosion from salt and fresh fluid, such as plastic, vinyl, stainless steel, or aluminum.

[0131] Subsequently, the siphon generator may be mounted on the exterior of the boat, typically at the water line. The positioning of the siphon generator at the water line is crucial as it allows the generator to create a vacuum that draws fluid from the bilge accumulator through the tube.

[0132] The siphon generator may be equipped with a suction hole that creates this vacuum and discharges the fluid outside the boat.

[0133] In operation, as the boat moves, fluid flows past the siphon generator. This flow of fluid, in conjunction with the design of the siphon generator, creates a Venturi effect, which results in a vacuum. This vacuum then pulls fluid from the bilge accumulator through the tube and expels it outside the boat, thereby removing fluid from the bilge.

[0134] This method of using the apparatus provides a continuous, hands-free fluid removal system that operates without the need for electrical power. It offers a robust solution for maintaining vessel safety and performance by ensuring a nearly dry bilge without manual labor or constant monitoring.
