Description
Background of the Invention
1. Field of the Invention
This invention relates to accessories employed in the use of muzzle-loading firearms, preferably rifles and pistols, and more specifically to the nipple wrench, used to loosen and tighten the nipples in the firearm to clean them or replace them with others, and the ramrod used in the operations of loading the firearms.
2. The Prior Art
Wrenches are usually made from a solid bar with one of its ends suitably machined, by milling, to provide two lateral lugs between whose lateral walls is housed the central portion of the nipple. For this purpose, such a nipple comprises bevels with the central portion, another threaded portion to be placed by the thread in an opening of the firearm and a third portion generally truncated conical on its outside in which the cap to be actuated by the hammer is received.
From the effects of continued use it becomes necessary at times to unscrew the nipple from its place in the firearm, both to clean it and to replace it with another, all of which requires continuous use of such a wrench, which results in breaking of the wrench lugs by the force applied and by the fatigue of the material itself.
On the other hand, the axial firing opening of the nipples themselves require frequent cleaning, and this is usually done with accessories for the firearm, for example, with pins or the like.
In this type of firearm there is a pin for achieving the connection between the barrel and the breech, and this pin is equipped on one of its outside ends with a reentrant groove into which the end of a screwdriver is normally applied, striking the pin for its extraction, to disconnect the barrel and breech.
Summary of the Invention
An object of the invention is to achieve a nipple wrench for muzzle-loading type firearms which eliminates the lugs of conventional wrenches, making its use safer and lengthening its useful life, while allowing the tightening force necessary for the nipple to be applied without risk of breaking.
Another object of the invention is achieving an inside space in the nipple wrench in which is housed two spare nipples, perfectly centered and immobilized in its interior.
Another object of the invention is to place an end plug on the wrench which is screwed to the free end and incorporates a needle which is introduced into the inside of the wrench going through the axial openings of the two nipples housed inside of it.
Another object of the invention is to provide a crosswise wrench pin for handling the wrench, with one end threaded and with the other end like the tip of a screwdriver.
Another object of the invention is making a ramrod for loading the firearm, with a stable and fixed positioning of the metal ends thereof which guarantees its continuous ability to function.
To make the nipple wrench according to the present invention, a cold-drawn tube is provided having a circular exterior and also a circular interior and equipped with two bevels or interfaces in the form of openings in the tube and disposed in parallel and at the same distance from the axis of the tube. This tube is later machined for providing an outside end portion truncated substantially conically.
In this machining, an axial cylindrical inside housing of greater dimension than the previous one is made, which is stopped at a distance approximately corresponding to the beginning of the larger base of the truncated conical outside end. The end portion of this cylinder inside is threaded a certain height, and below this threaded portion an axial perforation is made which forms two openings aligned for the rear housings of a wrench handling pin.
The pin is a cylindrical element whose outside diameter corresponds to the inside diameter of the axial perforations of the wrench body, such that it fits into the perforations with a slight amount of play. The pin has one end with a threaded projection of smaller diameter in which an operating handle or knob is screwed. The other end of the pin is made and shaped like a tip of a screwdriver.
An opening passes through the central portion of the pin across the pin relative to the axis of the pin. The utility of the opening will be seen below.
The nontruncated conical end of the wrench body is supplied with a kind of nut having a portion with a manually manipulable striated exterior, the other portion or neck at the front end is provided with threads, by which it is screwed to the end of the wrench body.
The free end of this nut, on the side of the interior of the wrench body, is made as an extension or cylindrical boss with a blind axial opening. The outermost front surface of this extension penetrates into the inside of the wrench body, once the threaded portion has penetrated into the corresponding end.
The blind axial opening of the nut receives on its inside an end of a cleaning rod which, as indicated, also goes through the nipples stored inside the wrench body. Further, the cleaning rod also goes through the crosswise opening of the pin and, at the same time it secures the nipples, it also secures the positioning of the pin.
This entire assembled unit, as said above, constitutes an independent unit able to be used as a wrench for handling the nipple as a nipple cleaning rod that can be reused and as a disassembly unit to act on the pin that connects the breech and barrel of the firearm.
It is to be noted that the truncated conical end of the wrench body is closed in its entire outside contour, and that its inside is partially circular with two opposite plane faces to house the central portion of the nipple, receiving the truncated conical end of the nipple. This inside section of the truncated conical end of the wrench which, when closed, receives perfectly the entire conntour of the nipple in its central portion, is more resistant and more lasting than the prior art devices.
When the firing passage of a nipple, which is mounted in the firearm, requires cleaning, it is loosened with the wrench and then extracted, the upper nut holding the cleaning rod being unscrewed to introduce the rod into the firing passage of the nipple, the wrench with the nut and rod later being fastened and the nipple screwed into the barrel.
To loosen the pin that connects the barrel and breech, the crosswise pin or handle is acted on either by removing it from the wrench by also removing the nut and cleaning rod or directly by acting on its end with pressure or a blow on the pin slot between the breech and barrel.
For its part, the barrel ramrod offers the advantageous feature that its end metal parts are located by being fastened by pressure also on the ends of the ramrod body itself, which is made of wood. The present invention avoids the troublesome positioning of the crosswise pins which secure the metal parts to the central body, by making some notches on the metal ends that penetrate into the wood of the body.
Preferably, these notches are made in groups of three, aligned in the direction parallel to the axis of the ramrod and distributed 102.degree. in each one of the two metal parts. Both the fastening and assembly are notably improved and a perfect fit is achieved.

Detailed Description of the Preferred Embodiments
As shown in FIG. 1, a conventional firearm is equipped with a breech 1 and barrel 3, a nipple 2 on which is placed a cap and which is acted on by the hammer and a plate 4 which receives a pin that connects barrel 3 and breech 1. The pin is provided with a groove 5 which is acted on to remove the pin to separate the barrel and breech.
FIG. 2 shows in perspective a conventional wrench 6 equipped with a pin or handle 9 fastened to the passing opening by projections 10 or any other means. The upper end of this wrench 6 comprises parallel lugs 7 to facilitate an entry point 8 for the nipple and opening 11 for receiving its conical end.
The wrench body 12 according to the present invention as shown in FIGS. 3 and 4 is made with a truncated conical end 16 which is totally closed and which provides a specific opening 15 receiving the nipple. The inside is provided with an opening 17 threaded on its upper end 19-20 up to a portion 13 and perforated crosswise by openings 18 below the portion 13.
Pin 21, as shown in FIGS. 5 and 6, to be inserted into and housed by openings 18, has a threaded end 22 at one end thereof. In another embodiment, the end 22 is not threaded and is pressure-fit to grip 25. The other end of pin 21 is formed like a screwdriver, having two flattened inclined surfaces. A central opening 24 is formed in pin 21 between the two ends so as to correspond substantially with the middle of hole 17 of wrench body 12 when pin 21 is inserted therein. An operating knob, grip 25 of FIG. 7 is positioned by screwing the inside of threaded hole 26 of grip 25 onto the threaded end 22 of pin 21 after the pin is inserted into the wrench body 12.
FIG. 9 shows a nut or support 31 which locks onto end 19-20 of wrench body 12 by screwing of portion 30 therein. Extension 32 of support 31 is equipped with perforation or opening 33 which receives end 28 of rod 27 shown in FIG. 8. A flattened zone 29 is formed in the vicinity of end 28 of rod 27, which will correspond to the depth of penetration of end 28 into perforation 33.
FIG. 11 shows the assembly of these parts, along with two nipples housed on the inside of wrench body 12. In FIG. 11 conical portion 38, central portion 39-40 and threaded portion 41 of the nipples can be seen. Once these nipples have been housed in the wrench body, pin or handle 21 and rod 27 with nut 31 are introduced so that rod 27 goes through opening 24 of handle 21 and through the firing passages of the nipples housed on the inside.
Opening 24 of handle 21 is 1.5 mm in diameter, for example, and the diameter of the rod is 0.6 mm to facilitate easy penetration of rod 27 through and to the nipples.
Pin 21 fits into the wrench body and opening 24 is perpendicular to end 23 with a screwdriver point so it is suitably positioned for penetration by rod 27.
FIG. 10 shows a view of the ramrod with its central portion 34 and metal lateral bushings 35 which exhibit some notches 36 that penetrate into wood body 34 and provide a suitable fit of the metal bushings 35 onto central portion 34.
To make the nipple wrench according to the present invention, a cold-drawn tube is provided having a circular exterior and also a circular interior and equipped with two bevels or interfaces in the form of openings in the tube and disposed in parallel and at the same distance from the axis of the tube. This tube is later machined by providing an outside end portion truncated substantially conically.
During this machining, an axial cylindrical inside housing of greater dimension than the previous one is formed, which is stopped at a distance approximately corresponding to the beginning of the larger base of the truncated conical outside end. The end portion of this cylinder inside is threaded a certain height, and below this threaded portion an axial perforation is made which forms two openings aligned for the rear housings of a wrench handling pin.
The pin is a cylindrical element whose outside diameter corresponds to the inside diameter of the axial perforations of the wrench body, such that it fits into the perforations with a slight amount of play. The pin has one end with a threaded projection of smaller diameter in which an operating handle or knob is screwed. The other end of the pin is made and shaped like a tip of a screwdriver.
An opening passes through the central portion of the pin across the pin relative to the axis of the pin. The utility of the opening will be seen below.
The nontruncated conical end of the wrench body is supplied with a kind of nut having a portion with a manually manipulable striated exterior, the other portion or neck at the front end is provided with threads, by which it is screwed to the end of the wrench body.
The free end of this nut, on the side of the interior of the wrench body, is made as an extension or cylindrical boss with a blind axial opening. The outermost front surface of this extension penetrates into the inside of the wrench body, once the threaded portion has penetrated into the corresponding end.
The blind axial opening of the nut receives on its inside an end of a cleaning rod which, as indicated, also goes through the nipples stored inside the wrench body. Further, the cleaning rod also goes through the crosswise opening of the pin and, at the same time it secures the nipples, it also secures the positioning of the pin.
This entire assembled unit, as said above, constitutes an independent unit able to be used as a wrench for handling the nipple as a nipple cleaning rod that can be reused and as a disassembly unit to act on the pin that connects the breech and barrel of the firearm.
It is to be noted that the truncated conical end of the wrench body is closed in its entire outside contour, and that its inside is partially circular with two opposite plane faces to house the central portion of the nipple, receiving the truncated conical end of the nipple. This inside section of the truncated conical end of the wrench which, when closed, receives perfectly the entire contour of the nipple in its central portion, is more resistant and more lasting than the prior art devices.
When the firing passage of a nipple, which is mounted in the firearm, requires cleaning, it is loosened with the wrench and then extracted, the upper nut holding the cleaning rod being unscrewed to introduce the rod into the firing passage of the nipple, the wrench with the nut and rod later being fastened and the nipple screwed into the barrel.
To loosen the pin that connects the barrel and breech, the crosswise pin or handle is acted on either by removing it from the wrench by also removing the nut and cleaning rod or directly by acting on its end with pressure or a blow on the pin slot between the breech and barrel.
For its part, the barrel ramrod offers the advantageous feature that its end metal parts are located by being fastened by pressure also on the ends of the ramrod body itself, which is made of wood. The present invention avoids the troublesome positioning of the crosswise pins which secure the metal parts to the central body, by making some notches on the metal ends that penetrate into the wood of the body.
Preferably, these notches are made in groups of three, aligned in the direction parallel to the axis of the ramrod and distributed 102.degree. in each one of the two metal parts. Both the fastening and assembly are notably improved and a perfect fit is achieved.
