(24) In describing the embodiment of the present invention, reference will be made herein to FIGS. 1-8 of the drawings in which like numerals refer to like features of the invention.

(25) The present invention provides a ramrod which requires no disassembly to use. The ramrod may comprise an adjustable length which may be overall longer than the muzzleloader barrel length, and may be collapsed into a position which is readily secured within the muzzleloader thimble(s). The ramrod of the present invention may include a removable loading tip to allow usage of different jags to perform a plurality of operations.

(26) Referring to FIGS. 1A and 1B, ramrod 20 comprises an elongated outer body 22 consisting of a material that will provide sufficient strength for loading operations, such as steel, aluminum, brass, a reinforced carbon composite, a polymeric material, and the like. Elongated outer body 22 comprises a length extending along longitudinal axis 23, and further comprises a first end 24, and a second end 26. One or both of first and second ends 24, 26 may include a hollow portion 23a, 23b (See FIG. 4) which may extend along a portion of the elongated outer body 22 or throughout the entirety of the body. First end 24 is designed for insertion into the bore of a muzzleloader during loading or cleaning operations and may include a loading jag 50 including an accessory end 52 for cleaning and/or loading operations. Second end 26 may be grasped by a user to facilitate loading operations. The overall length of the outer body 22 may vary as necessary to ensure capability with particular muzzleloader barrels.

(27) An inner body or extension member 80 may be included within the ramrod outer body 22 and may be movable within the outer body second end 26 from a retracted position where a portion of the length of extension member 80 is within outer body 22 (See FIG. 2), to an extended position where a portion of extension member 80 is outside outer body 22, thereby increasing the overall length of the ramrod 20.

(28) A detent housing 60 may be installed, mounted, inserted, or otherwise attached to the hollow portion 23b of the body's second end 26, and is described in further detail below. An extension arm 80 may be housed within an interior portion of detent housing 60, an interior of the outer body 22, or both. Extension arm 80 includes a clasping member 40 mounted at pivot point 81 (See FIG. 4) so that clasping member 40 may be selectively folded with respect to the ramrod's body. In FIGS. 1A and 1B the clasping member is shown in a working position, wherein it makes a substantial angle (e.g., 90 degrees) with respect to the ramrod's longitudinal axis 23. Clasping member 40 may fold about a central axis that is defined by a pivot pin 41 extending through pivot point 81 and secured to the clasping member within one or more openings 44. Clasping member 40 includes a counterbore 48 at one end 48 of the clasping member, and slotted section 42 extending along a length of the clasping member between pivot pin 41 and end 48. During operation, clasping member will be folded from the working position, as depicted in the illustrative views of FIGS. 1A and 1B, to the stowed position, such as the exemplary view of FIG. 2, so that the ramrod may be easily secured within the muzzleloader thimbles between usage. As seen in FIG. 2, clasping member is sized so as to be larger than the ramrod outer body 22, allowing the counterbore 48 of the clasping member to seat along the exterior of ramrod outer body end 24. To prevent shifting and contact between outer body 22 and clasping member 40, an O-rings, rubber grommets and the like (not shown) may be place between the clasping member 40 and outer body 22 which would ensure secured connection of the clasping member in the stowed position, but also prevent noise due to the shifting of the ramrod when secured within the thimbles which may otherwise alert prey during hunting.

(29) When in its working position, the clasping member 40 will provide a substantial area against which a user's palm may be pressed to facilitate loading or cleaning operations within the muzzleloader's bore.

(30) Detent housing 60 is now further described with reference to FIGS. 5A and 5B. As depicted, detent housing comprises a central channel 66 which may extend along the length of the detent housing for insertion of extension member 80 within such that detent housing encapsulates at least a portion of extension member 80. A retaining member 61 may be placed at an end of detent housing 60 which ensure the housing is properly secured to the ramrod body. The housing may further include one or more engagement channels 62 which extend along a length of the housing in a first direction from end-to-end 62a, 62b. A locking channel 63 may intersect engagement channel end 62b at a locking channel end 63a, and extend radially along a portion of the housing 60 in a direction approximately perpendicular to engagement channel 62 from end-to-end 63a, 63b. Engagement channel(s) 62 and locking channel(s) 62a are sized such that they will engage a locking element such as locking protrusion 82 of the extension member therein. Detent housing may be coupled to the ramrod body at hollow portion 23b via retaining member 61, which may be coupled to or integral with the detent housing and comprises a plurality of annular portions 61a, 61b. Annular portion 61b may be sized of an outer diameter comparable to the inner diameter of ramrod body, while annular portion 61b may be sized to an outer diameter comparable to that of the ramrod outer body 22. Retaining portion annular portion 61a may be secured to hollow portion 23b through fasteners, epoxy, threaded engagement, and the like.

(31) Operating the extension member 80 within detent housing is now described with reference to FIGS. 3A, 3B, and 3C, which depict the ramrod in an extended and locked position (FIG. 3C), retracted position (FIG. 3A), and an extended position (FIG. 3B). While the clasping member 40 of the illustrative views is depicted in the working position, the position of the clasping member is for clarity purposes only, and the present invention is not intended to be so limited, as the ramrod may be extended/retracted with clasping member 40 in any position or mode of operation. Starting with FIG. 3A, extension member 80 is in the retracted position wherein a portion of the extension member 80 extends within the detent housing central channel 66 opposite the retaining portion 61 and may extend within the ramrod body at hollow portion 23b (not shown). In the retracted position, locking protrusion 82 may be in communication with engagement channel end 62a opposite locking channel 63. With reference to FIG. 3B, moving the extension member in direction D causes reciprocal movement of locking protrusion 82 along engagement channel 62 until reaching the extended position where locking protrusion 82 contacts the opposing channel end 63a that intersects with end 63a of locking channel 63. Upon contact of the locking protrusion with the engagement channel end 62b, further movement of the extension member in direction D will be prevented. Referring now to FIG. 3C, rotation of the extension member 80 in direction R causes movement of the locking protrusion within locking channel 63 towards end 63b, so as to secure the extension member in an extended and locked position.

(32) In some embodiments, both ends of the engagement channel 62a, 62b may include locking channels disposed perpendicular to the engagement channel, so the ramrod may include an extended and locked position, as well as the retracted and locked position. In other embodiments of the present invention, engagement channel(s) 62 may include one or more locking channels along the length of the engagement which would other embodiments would permit incremental or fractional extension of the extension member, for example, extension, extension, extension and extension. The engagement channel(s) may similarly include a plurality of detent locations so that the user can tactically feel the extension/retraction progress of the extension member as it is moved in direction D. Extension member may similarly include of indicia or graduations which may indicate to the user the overall length of the ramrod and may correspond with any of the plurality of locking channels, so as to ensure the proper length specified for the muzzleloader barrel.

(33) In some embodiments, extension member 80 may comprise an endcap 84 to prevent further movement of the extension member in direction D. Endcap 84 may comprise a rigid material such as light-weight metals/alloys, or a resilient material such as an organic/inorganic polymeric material, rubber, and the like. Endcap 84 may be sized so as to engage with the interior walls of the outer body hollow portion 23b to prevent unnecessary movement of the extension member in the direction opposite direction D.

(34) In some embodiments, locking protrusion(s) may be sized so as to extend from the interior of the outer body 22 to an exterior portion of the outer body upon engagement of the locking protrusion(s) 82 in an extended, or an extended and locked position. In such embodiments, the locking element may comprise a biasing element 82 (See FIGS. 1A and 1B). Biasing element 82 may be spring-loaded or constructed of an otherwise collapsible or bias-able material so as not to restrict movement operations of the extension member during extension/retraction operations, while also forming a detent mechanism between outer body 22 and extension member 80. As shown in FIGS. 1A and 1B, biasing element 82 will be biased to extend outwardly from the central ramrod axis to the exterior of the outer body 22 via opening 21, restricting movement between extension member 80 and ramrod outer body 22. After engagement of the detent, further movement of the extension member within the detent housing 60 or outer body 22 is prohibited. Upon urging biasing element 82 toward the ramrod interior, the detent mechanism will be released and extension member 80 can be moved between extended and retracted positions.

(35) In some embodiments the detent mechanism may be engaged upon movement of the extension member to the extended position, without further rotation of the extension member to the locked position.

(36) With reference now to FIGS. 6A and 6B, an alternative embodiment of the detent mechanism is shown. Detent housing 160 comprises a terminal section 166, and a cut-out section 162 which houses a locking element such as lever arm 182 therein. Cut-out section 162 extends along at least a portion of the length of detent housing starting at terminal section 166 to allow movement of the rotating lever arm 182 during extension/retraction operations. Lever arm 182 includes pivot end 183 and a tab end 185 opposing pivot end. Lever arm is hingeably coupled to detent housing 160 via a resilient pivot end 183, such that lever arm 182 is permitted to translate in direction . Lever arm 182 is normally biased outwardly toward the exterior portion of the ramrod 20, allowing tab end 185 to protrude from the detent housing 160, ramrod outer body 22, or both. Tab end 185 extends in a direction generally perpendicular to the length of lever arm 182, such that upon movement of the extension member 80 to the extended or extended and locked position, tab end 185 will be biased through opening 21 to the exterior of the ramrod body, forming a detent mechanism restricting movement between extension member 80 and ramrod outer body 22.

(37) Extension member 80 may be coupled to detent housing 160 at end 184 within outer body 22. A retaining member 161 comprising a plurality of annular portions 161a, 161b of varying outer diameters may be placed in sliding engagement with extension member 80. Annular portion 161a may be sized to be received by the inner diameter of the ramrod body in a manner similar to that of the aforementioned retaining member. After coupling with the ramrod outer body 22, retaining member 161 will limit movement of the detent housing 160 to the interior portion of the ramrod body. In some embodiments, the interior of the ramrod body may include a guide track or similar mechanism to ensure proper movement and engagement of the detent mechanism as the extension member is moved to the extended and locked position. In other embodiments the detent mechanism may be engaged upon movement of the extension member to the extended and/or extended and locked position.

(38) Turning now to FIGS. 7A and 7B, an alternative embodiment of the detent mechanism for use with the ramrod of the present invention is shown. Detent housing 260 comprises a generally cylindrical housing which includes aperture 262. The interior of detent housing 260 includes the detent assembly formed from a resilient member 288, which may comprise a spring, clastic and the like, a biasing element 287, and the locking element 282. Biasing element 287 comprises a tapered nose 289 for communication with concave portion 283 of locking element 282. Biasing element 287 is normally translated by resilient member 288 in a direction towards extension member end 184, causing the tapered nose 289 to contact concave portion 283, which results in translational movement of locking element 282 perpendicular to the translation of the biasing element. Thus, biasing element 287 will be urged to protrude from detent housing aperture 262, which will also allow the biasing element to extend to the exterior surface of the ramrod outer body 22 once placed in the extended and locked position, forming a detent mechanism in accordance with the embodiments described herein. Upon depression of the locking element 282 towards the axial center of the ramrod 20, biasing element will be translated away from the extension member end 184, such that the detent mechanism will be released and the extension member may be moved from the extended to retracted positions. Retaining member 161 will limit movement of the detent housing 260 to the interior portion of the ramrod body. In some embodiments, the interior of the ramrod body may include a guide track or similar mechanism to ensure proper movement and engagement of the detent mechanism as the extension member is moved to the extended and locked position. In other embodiments the detent mechanism may be engaged upon movement of the extension member to the extended position, without need for rotational movement.

(39) Referring now to FIG. 8, the body first end 24 is shown in connection with loading jag 50. Loading jag 50 may be removably coupled within hollow portion 23a of first end 24 by a connection portion 51, which may be threaded or otherwise configured for removable attachment. An accessory end 52 opposite connection portion 51 may comprise a concave portion for facilitating loading operations or serrated edges to grip a cleaning patch (not shown) during cleaning operations.

(40) FIGS. 9A and 9B depict a side and cross-sectional view of a ramrod according to one embodiment of the invention. Ramrod 20 includes an elongated outer body 22 which receives extension member 80. With additional reference to the plan views of FIGS. 10A and 10B, extension member 80 includes a detent member 360 couplably engaged with the extension member in an interference assembly. The substantially cylindrical detent member 360 may be sized to a larger diameter than extension member 80 at shoulder 303 to prevent disengagement between the extension member and the outer body. Detent member 360 comprises an engagement portion 363 may form a plurality of threads 362, or other similar locking mechanism. Threads 362 may comprise a double lead thread, single lead thread, and the like. Engagement portion 363 forms a truncated engagement portion of the detent member 360, which is sized to engage the interior of the outer body in a transition fit. Engagement portion 363 may form any length of the detent member 360, such as 0.25 in overall length of the detent member. Detent member 360 may be sized to any length which provide structural rigidity within the outer body 22, such as 1.00 in length. Engagement portion 363 may be truncated to a size of 5/16 with 24 threads per inch and a pitch diameter of 0.2843-0.2788. The overall height of engagement portion 363 may be sized to fit within the outer body 22 while having a major thread diameter larger than the pitch diameter to ensure locking strength of the engagement portion 363.

(41) A capture element 361 is couplingly secured to the open end of the outer body 22, forming an enclosure to the extension member 80. Capture element 361 includes interior coupling portion 365 for communication with the engagement portion 363. Upon moving the extension member 80 to the extended position, a user may simply rotate the extension member 80 relative to the outer body 22, securing the engagement portion 363 within coupling portion 365. Once secured, the user may perform loading operations using the ramrod, and may then subsequently disengage the capture element and engagement portion via a counter-rotation, to move the extension member to the retracted position. The extension member may include one or move grooves 301 to indicate when the extension member 80 is in a fully extended position.

(42) The method of using the ramrod of the present invention of one or more embodiments is described as follows. During loading operations, ramrod 20 is removed from the muzzleloader's securing thimble(s) and ramrod extension member 80 may be extended by pulling the clasping member 40 in a direction along the ramrod longitudinal axis 23. After reaching a mechanical stop or limiter, the user may rotate the extension member 80 with respect to the body axis 23. After reaching a particular angle of rotation, for example 90-degrees, a locking protrusion/biasing element may be released through the ramrod aperture 21 to the exterior of outer body 22, forming a detent mechanism between the ramrod and the extension member. The clasping member 40 may be folded into a working position subsequent to locking the extension member 80 into the extended position or may be placed into the working position prior to extension. To return the ramrod to the retracted and stowed position, the user may subsequently depress the locking protrusion/biasing element to release the detent mechanism and subsequently rotate extension member 80 to an unlocked position, where the extension member 80 may be translated back within the ramrod body interior such that extension member 80 is in the retracted position. Clasping member 40 may be subsequently folded back into the stowed position, and the ramrod may be reinserted within the thimbles until further use is necessitated.

(43) Thus, the present invention provides one or more of the following advantages: a ramrod which requires no disassembly to use; an adjustable ramrod which can include a length longer than the muzzleloader barrel length; and a ramrod with removable loading tip to allow usage of different jags to perform a plurality of operations.

(44) While the present invention has been particularly described, in conjunction with one or more specific embodiments, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. It is therefore contemplated that the appended claims will embrace any such alternatives, modifications and variations as falling within the true scope and spirit of the present invention.
