Breach-'Loading Fire-Arm. v No. 25,470. Patented sept.' 13, 1859.
Specification forming part of Letters Patent No. 25,4170, dated September 13,1859.
To all whom t may concern,.-
Be it known that I, JOSEPH RIDER, of Newark, in the county of Licking and State of Ohio, have invented certain new and useful Improvements in Pistols; and I do-hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a longitudinal central section of a pistol with my improvements. Fig. 2 is a top View of the same. Fig. 3is a perspective View of what I call the cap-tube.77 Fig. 4 is a front view of the breech-pin.
Similar letters of reference indicate corresponding parts in the several gures. l
My invention consists in a novel combination of a movable breech-pin and tube for the reception of a percussion-cap applied to apistol, as hereinafter described, for the purpose of employing for the charge the powder contained in the cap, and making a very convenient and efcient pistol of small size.
It further consists in a certain construction of the parts of the lock and arrangement thereof within the stock of the pistol, and in relation to the barrel, for the purpose of bringing the parts within a small compass.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.
A is the barrel, cast with or screwed into the stock B. On one side of the stock is ay plate, C, made movable for the purpose of inserting the parts of and examining or oiling the lock, and secured in place by a screw, D. The barrel is open at the rear end, and counterbored to receive the cap-tube E and breechpin F. The breech-pin F and the front portion of the cap-tube E are fitted snugly, but easily, into the counterbore of the barrel, sov that they may be inserted and taken out without difficulty. The rear portion of the captube is turned down much smaller than the front part to constitute the nipple a, for the reception of the percussion-cap c, Fig. 1, and in front of the nipple it is made rather larger than the exterior of the cap, as shown at b in Figs. l and 3, and this part b is fitted snugly but easily into a cavity, d, in the frontfof the breech-pin, said cavity being of a depth about equal to the length of the nipple and part b of the tube, so that the head of the cap, intervening between the end of the nipple and the back of the cavity, may prevent the whole of the part b entering the breech-pin. On one side of the breech-pin, close to its rear end, which projects from the counterbore of the barrel, there is a small lever, f, which is intended to drop into a notch, e, in one side of the stock, for the purpose of preventing the breech-pin and cap-tube dropping out from thecounterbore of the barrel, and this'notch e is wide enough to permit the breech-pin moving a short distance longitudinally.
G is the hammer, working upon the pin g, which occupies very nearly the same position as the hammer-pin of other pistols. The hammer is of peculiar form, the lower part of the front ofits thumb-piece h constituting the face, which strikes upon the rear end of the breechpin and a cavity, it', Fig. l, being provided behind the pin g and between the said pin and the thumb-piece to receive the extremity of the V-shaped mainspring H, which is connected 1' .with the hammer below the pin g by a stirrup,
j, and which is held in place between the front ofthe stock and a projection, k, Fig. l, at the' bottom thereof. I, Fig. 1, is the trigger, working upon the pin Z, and carrying its own sear m, which engages with a notch, n, in the front part of the hammer. p is the trigger-spring.
To load, the hammer is cocked and the breech-pin F turnedto free its lever f of the notch e, and then drawn out, bringing with it the cap-tube E. The cap-tube is then drawn out of the cavity of the breech-pin and the cap placed on the nipple, and the cap-tube is then replaced in the breech-pin, the ball q (represented in red color in Fig. I) having been pre-l viously placed in the rear of the barrel. The firing may be then immediately effected by pulling the trigger, or the hammer may belet down gently upon the breech-pin till the piece is required to be fired, when it is to be recocked by drawing back the hammer. When the trigger is pulled, the hammer falls against the rear end of the breech-pin and drives the latter forward against the cap, and as the front end of the cap-tube bears against the front end of the counterbore of the barrel, the cap is exploded, and the force of the explosion being confined by the breech pin is all expended upon the ball, and causes it to be projected from the barrel.
The cap employed may be an ordinary percussion-cap, or a cap with 2L strenger charge form herein described, the arrangement of Specially made for the purpose. the maiiispring and trigger relatively to each WhatI claim as my invention, and desire to other, to the hammer, and to the stock and secure by Letters Patent, is barrel, substantially as herein described.
l. The combination of the movable breech- JOSEPH RIDER.
