DETAILED DESCRIPTION

[0031] In the following detailed description of the invention, numerous details, examples, and embodiments of the invention are described. However, it will be clear and apparent to one skilled in the art that the invention is not limited to the embodiments set forth and that the invention can be adapted for any of several applications.

[0032] The system, device, and method of the present invention may be used to clean a rotary cutting tool such as a drill bit and/or reamer and may comprise the following elements. This list of possible constituent elements is intended to be exemplary only, and it is not intended that this list be used to limit the device of the present application to just these elements. Persons having ordinary skill in the art relevant to the present disclosure may understand there to be equivalent elements that may be substituted within the present disclosure without changing the essential function or operation of the device.

[0033] The various elements of the system, device, and method of the present invention may be related in the following exemplary fashion. It is not intended to limit the scope or nature of the relationships between the various elements and the following examples are presented as illustrative examples only.

[0034] By way of example, and referring to FIGS. 1-8, some embodiments of the invention include a rotary cutting tool cleaning system, device, and method 10 for cleaning debris and shavings from a rotary cutting tool 30, such as a drill bit, reamer, and the like. The cleaning system, device, and method 10 of the present invention generally comprises at least one cleaning member 12 rotatably mounted within a cartridge or housing 14. The cleaning member 12 is designed to engage and remove debris from the rotary cutting tool.

[0035] More specifically, as illustrated in FIG. 1, the cartridge 14 of the cleaning system 10 comprises a top or cap 16 having at least one opening or hole 18 extending through it and configured to receive a portion of the rotary cutting tool 30. The cartridge 14 may also include a bottom or floor 20 opposite the top or cap 16. A side wall 22 extends between the top or cap 16 and the bottom or floor 20, all of which defines the interior 24 of the cartridge 14. The cartridge 14 may comprise any durable material such as plastic, metal and the like. A generally rigid plastic material may be used to provide a light and portable system.

[0036] Turning now to FIGS. 4-6, the cartridge 14 is configured to hold or contain one or more cleaning members 12 within its interior 24. The cleaning members 12 may comprise rollers that can be rotatably mounted within the interior 24 of the cartridge 14 to aid in removing and containing the debris from the rotary cutting tool 30. While the cleaning members 12 are illustrated in a vertical orientation within the cartridge 14, it is also contemplated herein that the cleaning members 12 can be oriented in any direction within the cartridge 14.

[0037] As particularly illustrated in FIGS. 5A-5D, the top or cap 16 may include a seat or socket 26a on its lower surface 27a and the bottom or floor 20 includes a seat or socket 26b on its upper surface 27b. The seat or sockets 26a and 26b are aligned or in registration with each other and configured to receive posts 32a and 32b the seat or socket 26a. The arrangement of the sockets 26a, 26b, and posts 32a, 32b, permit axial rotation of the cleaning members 12. It is also contemplated herein the posts may extend from the top 16 and bottom 20 that are insertable into sockets formed in the ends of the cleaning members 12. While not illustrated, bearings and other rotational friction reduction aids may be employed between the cleaning members 12 and the cartridge 14.

[0038] In one example embodiment of the present invention, the bottom or floor 20 of the cartridge includes one or more openings 29 extending through it. The openings 29 are configured to permit the debris removed from the rotary cutting tool 30 to fall out of the cartridge 14 as it is removed. In another example embodiment of the present invention, there are no openings in the bottom or floor 20 of the cartridge 14. Instead, the bottom or floor 20 is removable or detachable from the cartridge 14 for emptying of the collected debris. The bottom or floor 20 may comprise a side wall 32 that is insertable into the interior 24 of the cartridge 14 while the debris is being collected during the cleaning process. The side wall 32 of the bottom or floor 20 acts to contain the collected debris in the bottom or floor 20 until such time that it is removed from the cartridge 14 for emptying. In another example embodiment, the cartridge 14 may comprise a lower drawer that collects the debris and that can either be opened or removed for emptying the debris.

[0039] As illustrated in FIGS. 6 and 8, the cleaning members or the roller 12 have a plurality of outwardly extending engagement members 40 that are designed to engage and remove the debris from the rotary cutting tool 30. In one example embodiment, the engagement members 40 comprise one or more bristles or bunches of bristles 40. The engagement members 40 are preferably rigid enough to be able to remove the debris from the rotary cutting tool 30 but flexible enough to be able to bend around the surface of the rotary cutting tool 30. The engagement members 40 may comprise any materials including but not limited to brass, copper, or any other metal material. The engagement members 40 may also comprise a generally rigid plastic or synthetic material.

[0040] As particularly illustrated in FIGS. 6 and 8, the arrangement or orientation of the cleaning members 12, engagement members 40 and the rotary cutting tool 30 aid in effectively cleaning or removing debris stuck in the flutes of the rotary cutting tool 30. In one example embodiment, the cleaning members 12 are positioned generally adjacent to each other such that the engagement members or bristles 40 touch, overlap, or engagement each other. The rotary cutting tool is positioned adjacent to or between the cleaning members 12 such that the engagement members or bristles 40 engage or contact the surface of the rotary cutting tool 30. Different arrangements or configurations are possible depending upon the rotary cutting tool and the debris stuck in the flutes. For example, a stronger or more rigid engagement member or bristle 40 may be required for stuck metal debris but a softer or more pliable engagement member or bristle 40 may be used for wood debris.

[0041] As illustrated in FIGS. 1 and 2, the system 10 of the present invention may also include a vessel or container 50 to hold and dispense a liquid 52 such as water, oil, or a penetrant into the interior 24 of the cartridge 12. The container 50 includes a spout 54 that is insertable into an opening 56 extending through the top 16 of the cartridge 14. The liquid 52 flows out of the container 50 through the spout 54 and onto the rotary cutting tool 30. The liquid 52 aids in removing the debris and carrying to the bottom 20 of the cartridge 14. In one example embodiment, as illustrated in FIG. 4, the bottom 20 contains a screen or filter 60 to capture the debris while allowing the liquid to flow passed it. The screen enables the debris and liquid to be separated for easier cleaning. The screen may be removable from the bottom 20 for cleaning and replacement.

[0042] As illustrated in FIGS. 1-3, the system 10 may include a carrier 60 having at least a first recess 62 extending into it for receiving the cartridge 14. The first recess 62 may include a peripheral wall 64 that at least partially encircles the cartridge 14 to aid in preventing it from spilling over. The first recess 64 of the carrier 60 also has a shape designed to hold the cartridge 14 without any or with minimal rotational movement. As will be explained below, preventing rotational movement of the cartridge 14 is important when cleaning a rotary cutting tool 30.

[0043] In another example embodiment of the present invention, at least the first recess 62 comprises at least one inner shoulder 65 extending at least partially about its inner surface. The shoulder 65 is configured to hold the cartridge 14 above a work surface. The carrier 60 also may comprise at least one hole 66 extending through its peripheral wall 63 to allow the liquid 52 to flow out of the carrier 60. The hole 66 may be closed by a plug member (not shown).

[0044] In another example embodiment of the present invention, the carrier 60 comprises a second recess or portion 68 designed to hold the container 50. The peripheral wall 63 of the carrier 60 near the container 50 may have a cutout 69 to permit easier placement and removal of the container 50. The first recess 62 and the second recess 68 may be separated by a divider or wall 70 extending or formed in the peripheral wall 62 of the carrier 60.

[0045] As will be explained below, operation of the system of the present invention can be accomplished by utilizing the power supply or battery of the device used with the rotary cutting tool 30. For example, a handheld drill having a rechargeable battery can be used to operate the system 10 while cleaning the rotary cutting tool or bit 30. By utilizing the power supply of the device that uses the rotary cutting tool 30 a user does not have to worry about charging another battery or power supply. The present invention can also be used with manually operated tools such as manual hand drills and the like. In either case, once a user actuates the battery or power supply of the rotary device it will rotate the system 10. Similarly, once a user manually rotates a hand drill the rotation of the rotary cutting tool 30 will operate the system 10 of the present invention. In another embodiment of the present invention, the system 10 of the present invention can include its own power supply that can be integrated, replaceable, removable, re-usable, and/or rechargeable.

[0046] In use, a user may remove the top 16 of the cartridge or housing 14 and insert one or more cleaning members or roller 12 into its interior 24. The user may then replace the top 16, making sure that the cleaning members or roller 12 are positioned in the sockets 26a and 26b so that they may rotate freely about their axis. The user then places the cartridge 14 into the first recess 62 of the carrier, which holds it and prevents it from rotating. Next, the user inserts the rotary cutting tool 30 into the opening 18 of the top 16. The rotary cutting tool 30 is positioned such that its insertion into the cartridge causes it to come into contact with the cleaning members or rollers 12.

[0047] A user then connects a drill or other rotation imparting tool to the shank of the rotary cutting tool 30. The user then switches or powers on the drill. As the drill rotates the rotary cutting tool 30 its rotational movement is imparted onto the cleaning members or rollers 12. The cleaning members or rollers 12 will continue to rotate as long as the rotary cutting tool 30 is rotating. As the cleaning members or rollers 12 and the rotary cutting tool 30 rotate they engage each other causing the engagement members or bristles 40 to engage the debris in the flutes of the rotary cutting tool 30. Because the rotation of the rotary cutting tool 30 creates rotation of the cleaning members or rollers 12, the rotary cutting tool 30 cannot cut or degrade the cleaning members or rollers 12, as compared to a rigidly mounted brush design.

[0048] As the engagement members or bristles 40 cause the debris and shavings to dislodge from the flutes of the rotary cutting tool 30, they fall to the bottom 20 of the cartridge 14. The bottom 20 can be removed from the cartridge 14 to dispose of the debris and shavings. Alternatively, a user may squeeze the container 50 to force a stream of liquid 52 through the spout 54 and into the opening 56 of the top 16 of the cartridge 14. The liquid 52 then flows down onto the rotary cutting tool 30 and bristles 40 flushing the debris and shavings into the bottom 20 of the cartridge 14.

[0049] If a screen 60 is present in the bottom 20 of the cartridge 14, it may trap the debris and shavings while permitting the liquid 52 to flow lower into the bottom 20. In this way, the user is able to pour the liquid 52 out of the hole 66 in the carrier 60 first and then dump the debris and shavings into the trash.

[0050] Once the rotary cutting tool 30 is cleaned off, the user may remove the rotary cutting tool 30 from the device 10. A user may also remove and clean the cleaning members or rollers 12 by removing the top 16 and pulling the rollers 12 out of the interior 24 of the cartridge 14. The cleaning members or roller 12 may be washed, or blown clean with pneumatic air and then placed back into the interior 24 of the cartridge 14.

[0051] The drill bit cleaning device 10 of the present disclosure may be made of any suitable materials and may have dimension suitable for cleaning any desired rotary cutting tool or other rotating tool, such as a reamer.

[0052] The above-described embodiments of the invention are presented for purposes of illustration and not of limitation. While these embodiments of the invention have been described with reference to numerous specific details, one of ordinary skill in the art will recognize that the invention can be embodied in other specific forms without departing from the spirit of the invention. Thus, one of ordinary skill in the art would understand that the invention is not to be limited by the foregoing illustrative details, but rather is to be defined by the appended claim.
