Abstract
A barrel thimble for securing a ramrod to a barrel of a muzzle-loading firearm. The thimble includes a hollow tubular sleeve portion and flanges extending from the sleeve portion for engagement within recesses formed in the barrel of the firearm.
Description
- The present invention relates generally to the field of firearms and, more particularly, to an improved apparatus for securing a ramrod or other equipment used in association with muzzle-loading firearms to the barrel.
- In a typical muzzle-loading firearm (including without limitation, muzzle-loading rifles, muskets, shotguns, pistols, cannon, and the like), the main powder charge and the projectile are manually loaded into the muzzle of the firearm. Many such firearms utilize a ramrod during the loading process to seat the powder and projectile against the breech of barrel. The ramrod is typically stored directly beneath the barrel of the gun and is secured in place by at least one barrel thimble as depicted in
FIG. 1 . Typically, thimbles are hollow tubes, which permit a user to slide a ramrod therein to support and house the ramrod when not in use. In the prior art, thimbles are typically attached to the barrel of the gun with at least one separate connector such as a screw or bolt, as shown inFIGS. 1 and 2 . - Attaching a thimble to the barrel of the gun using this method can present many problems in the manufacturing process and may compromise the structural integrity of the firearm. In order to utilize this method, a manufacturer must first drill one or more appropriate sized holes in both the barrel and the thimble to accommodate the screw, and the barrel must be tapped to accept the screw threads. Additionally, the screw must be guided through the thimble and inserted into the barrel. Furthermore, the screw and barrel hole must be coated with a bonding agent or adhesive to keep the thimble from vibrating loose. And the thimble typically is a somewhat complex casting, with a radiused or angled recess to match the barrel's external geometry, adding to expense. This procedure takes a considerable amount of time to complete and is costly for the manufacturer. Furthermore, drilling into the barrel of a firearm may compromise the structural integrity of the firearm and/or present a potential rusting point.
- Accordingly, it can be seen that needs exist for improved barrel thimbles and methods for securing a ramrod to a muzzle-loading firearm. It is to the provision of an improved method and apparatus meeting this and other needs that the present invention is primarily directed.
- The present invention provides an improved barrel thimble and an improved method of securing a ramrod or other equipment to the barrel of a muzzle-loading firearm. In example embodiments, the thimble includes a sleeve portion for receiving the ramrod, and a pair of flanges integrally formed with the sleeve portion for engagement within cooperating recesses formed in the barrel. The thimble preferably flexes to facilitate installation, and is resiliently biased into engagement with the barrel to securely hold the thimble in place.

- In another aspect, the invention is a muzzle-loading firearm comprising a barrel, a ramrod for loading a projectile into the barrel, and a barrel thimble for removably securing the ramrod to the barrel when the ramrod is not in use. The barrel thimble preferably includes a sleeve for receiving the ramrod, and integral attachment means for attaching the sleeve to the barrel without separate connectors.
- In another aspect, the invention is a barrel thimble for securing a ramrod to a barrel of a muzzle-loading firearm, the barrel thimble including a sleeve and an opposed pair of flanges extending from the sleeve.
- In another aspect, the invention is a barrel thimble for securing a ramrod to a barrel of a muzzle-loading firearm. The thimble preferably includes a sleeve portion formed as a hollow tubular element having a generally circular cross-section extending lengthwise about a longitudinal axis, and having an open end. A pair of opposed flanges preferably extend from the sleeve portion adjacent the open end, each flange having a tip edge extending generally parallel to the longitudinal axis of the sleeve.
- In another aspect, the invention is a method of attaching a barrel thimble to a barrel of a muzzle-loading firearm. The method preferably includes the steps of flexing an opposed pair of flanges of the barrel thimble against the thimble's internal resilient bias, and releasing the flanges to allow tip portions of the flanges to engage within recesses formed in the barrel of the muzzle-loading firearm.

- Referring now to the drawing figures,
FIGS. 3-6 depict a thimble apparatus according to a first exemplary embodiment of the present invention. Thethimble apparatus 10 is shown inFIGS. 3 and 4 mounted onto abarrel 20 of a muzzle-loading firearm 30. As depicted, thethimble 10 is mounted on a muzzle-loading rifle, but it can be readily adapted for use on other types of muzzle-loading firearms by persons of ordinary skill in the art. - The
thimble 10 preferably comprises a generally tubularhollow sleeve portion 15 for receiving and housing aramrod 5 when the ramrod is not in use. It is preferable that thesleeve portion 15 of thethimble 10 has a generally circular, octagonal, or otherwise configured cross-section that extends about alongitudinal axis 17. In the depicted embodiment, the sleeve defines a slotted top opening 19 permitting the sides of the sleeve to flex relative to one another. Thethimble 10 further comprises at least one, and preferably two,flanges 12 extending from the top of the thimble as depicted inFIG. 4 , on either or both sides of theslot 19. It is preferable that thethimble 10 is made out of stainless steel, brass, or other metal, but one of ordinary skill in the art will recognize that the material properties of the thimble can vary. Theflanges 12 preferably extend from the edges of the sleeve adjacent theopen slot 19 at the top of thesleeve portion 15 of the thimble, and have a smoothly curving profile to minimize stress concentrations and provide flexure during installation. Each flange can comprise a single continuous element extending along the length of the thimble, or two or more fins or fingers spaced at intervals along the length of the thimble. In the depicted embodiments, eachflange 12 comprises an inwardly-recessed (concave when viewed from the thimble's exterior)portion 14 adjacent its point of connection with thesleeve portion 15, an outwardly-curved (convex)portion 16 distal the inwardly-recessed portion from the sleeve, and terminates in an inwardly and distally directed fin ortip 18. - Flexure of the
sleeve portion 15 and/or theflanges 12 allows the tips of theflanges 12 to be retracted away from one another (expanding the open-slotted top 19), and the resilience or shape-memory of the sleeve's material biases the flanges back toward one another, to facilitate installation of the thimble and retain it in place on the barrel. Theflanges 12 preferably also provide resilient flexure at the inwardly and outwardlycurved portions sleeve 15 does not include a slotted open top, and the flanges provide the flexure for facilitating installation and securing of the thimble to the barrel. And in still further embodiments, the sleeve portion provides the flexure and the flanges are substantially rigid. - In preferred embodiments, the inside diameter of the
sleeve portion 15 of thethimble 10 is slightly larger than the outer diameter of the ramrod, to provide a running interference fit to secure the ramrod in place and to minimize vibration of the ramrod against the barrel when not in use. In example embodiments, it is preferred that theflanges 12 extend from and be integrally formed with thesleeve portion 15, as depicted inFIGS. 5 and 6 . In order to secure the ramrod within thethimble 10, it is preferred that thesleeve 15 and therecessed portion 14 have inner contours generally conforming to the outer contours of the ramrod. Additionally, portions of theflanges 12 between the inwardly-recessedportion 14 and the outwardly-recessedportion 16 are preferably shaped to generally match the outer contour of thebarrel 20 to provide more secure attachment and minimize vibration of the ramrod. - The
thimble 10 preferably engages thebarrel 20 via at least one, and preferably twoslots 22 or other recesses formed in the barrel. Theslots 22 are preferably continuous channels or grooves formed in thebarrel 20 adapted to receive the tip edges 18 of theflanges 12. In alternate embodiments wherein eachflange 12 comprises one or more spaced-apart fins or fingers, theslots 22 can take the form of one or more discontinuous short channel segments or holes spaced along the barrel. In further alternative embodiments, the slots are formed by the intersection of thebarrel 20 and one or more ridges or other projections extending outwardly from the barrel. Theslots 22 are preferably aligned generally parallel to one another, and are spaced a distance apart from one another that is slightly greater than the unflexed spacing between theflanges 12 of the thimble, such that the resilience of the thimble holds the flanges snugly in the slots when the thimble is installed, preventing inadvertent removal of the thimble from the barrel. Preferably theslots 22 span the length of thethimble 10 as depicted inFIG. 3 . However, in alternate embodiments the slots may be longer than the thimble or may only be as long as cooperating portions of theflanges 12. Theslots 22 are preferably angularly offset from one another about the periphery of the barrel by between 45° and 75°, and most preferably by about 60°. In the depicted embodiment, theslots 22 are angled towards each other to accommodate inwardly-directedflanges 12. In alternate embodiments, theslots 22 are directed parallel to one another, or are directed away from each other to receive outwardly-directed flanges. In alternate embodiments, the flanges directly engage the outer surface of the barrel, rather than being received within recesses formed in the barrel. - The thimble of the present invention is preferably quick and easy to install. In one form of the invention, the
flanges 12 are pulled apart for insertion into theslots 22. The resilience of thethimble 10 will cause theflanges 12 to spring back toward their unbiased position and secure the thimble to thebarrel 20. In these embodiments, thetips 18 of theflanges 12 are preferably angled inwardly towards each other such that when the flanges are pulled apart and inserted into theslots 22, the thimble is secured to thebarrel 20 by inward bias of the tips of the flanges. In alternative embodiments, thetips 18 of theflanges 12 are directed outwardly, in opposite directions, such that the flanges are pressed together for insertion into outwardly-angled slots 22, and the thimble is secured to the barrel by outward bias of the flanges. Because thethimble 10 does not require a bonding agent to prevent it from vibrating loose, it may be easily removed for cleaning or repair if necessary, and replaced using the procedures outlined above. - While the thimble of the present invention has been described as utilized to secure a ramrod to the barrel of a muzzle-loading firearm, it will be recognized that minor modification within the level of skill in the art can be made to allow the thimble to secure other items to a firearm, such as for example, front and/or rear sights, telescopic sights, carrying slings, and the like.
- While the invention has been described with reference to preferred and example embodiments, it will be understood by those skilled in the art that a variety of modifications, additions and deletions are within the scope of the invention, as defined by the following claims.
