SAFETY-SEAR.

SPECIFICATION forming part of Letters Patent No. 520,596. dated May 29, 1894.

Application filed August 7, 1893- Serial No, 482,568. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE A. HORNE, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Hammerless Breech- Loading Guns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is an improvement in hammerlessbreech loading fire arms and consists in the novel features hereinafter described, reference being had to the accompanying drawings which illustrate one form in which I have contemplated embodying my inven tion, and said invention is fully disclosed in the following description and claims.

The object of this invention is to provide the sear with a safety stop lying normally in position to arrest the hammer and prevent its accidental discharge, the said stop being removed from the path of the hammer when the trigger is pulled to discharge the gun.

Referring to the said drawings: Figure 1 represents a side elevation partly in section of a part of a fire arm embodying my invention. Fig. 2 is a view similar to Fig. 1 with the portions of the barrels shown in that figure, removed, and showing the parts in different positions. Fig. 3 is a top view of one of the sears.

In the drawings, reference being had to the letters marked thereon, A represents the top portion of the gun and B the barrels of ordinary construction provided with the usual lug b for engaging the stock, inthe customary manner. The stock A is provided with a suitable lock casing in which is secured the pivot pin 0 upon which the hammers G O are mounted. Each hammer is provided with a firing projection c beneath which is a shoulder 0 slightly in rear of said firing projection, and the upper face or edge of the hammer is provided preferably with two locking notches c and 0 adapted to be engaged by the sear. Each hammer is provided with a forwardly extending cocking arm 0' which is adapted to engage a recess 6 in the side of the lug b and said lug is provided with solid portions b which I'term cockingshoulders,be1ow said recess 6 to operatively engage the forward end of the cooking arm 0' as clearly shown in Fig. 1. In the drawings I have represented for olearness, but one hammer, cocking arm and sear, but itwill be understood that the lock will be provided with, a hammer and its adj unctive device for each barrel. In order that the arms 0' may properly engage the lug b and yet that the hammers may have their firing projections in line with the bores of the barrels, I prefer to locate the hammers C and arms 0 in different vertical planes and the two parts may be formed in one piece or in two pieces suitably joined together. It will thus be seen that the lowering of the barrels will cause the cooking shoulders 17 of the barrel lug to raise the cocking arms O and depress the hammers O 0, against the force of their respective main springs C 0 D represents one of the sears, there being one for each hammer, which is pivoted to the lock casing by a pin d and has an angular shoulder d adapted .to engage one of the notches c o in the upper edge of the hammer." Thesear D is shown in detail in Fig. 3 which represents a top View of the same. Each sear is provided with a rearwardly extending arm d having a lug or projection at its end extending laterally to engage one of the triggers E, and the said sear is also provided with a forwardly extending arm d having at its end a safety lug or projection d which is normally in the path of the hammer O and will be engaged by the shoulder c of the same if the hammer should be accidentallyjarred off, thereby preventing the hammer from striking the cartridge, as shown in full lines in Fig.2. A spring D engages the lock casing and also the sear and holds it normally in the position shown in Fig. 1 and in full lines in Fig. 2. It will thus be seen that if the sear is accidentally jarred out of one of the notches of the hammer it willv be held by the spring D in position so that the hammer will be held or caught by the safety lug 01 It is to be noted that the sear itself is thus provided with a safety attachment for preventing the accidental discharge of the gun when the hammer is released by any other means than by a proper operation of the triggen. When however, the trigger E is pulled back, the rear end of the sear is raised, and

the forward arm with the projection 01 depressed so that when the hammer is released the stop or safety device 01 will have been removed from the path of the hammer and the point of the hammer Will be able to strike the cartridge as shownin dotted linesin Fig. 2. I prefer to form the forwardly extending arm (1 of the sear of such length that the safety lug 01 will normally rest against the front wall a of the lock casing as shown in Figs. 1 and 2 so that when the trigger is accidentally released a part of the stock will be borne by the said walla thus avoiding injury to the safety lug.

When it is desired to separate the barrels from the stock of the gun, the fore end is removed and the barrels depressed a greater distance than is permitted when the gun is broken ordinarily to cock the hammer. The cooking shoulders will raise the cooking arms C G into the position indicated in dotted lines, Fig. 1, and depress the hammers so that the sear will engage the second notch 0 and hold the hammer until the parts of the gun are again assembled.

I do not desire to be limited to the exact details of construction herein shown and described as variations may be made therein without departing from the spirit of my invention.

WVhat'I claim, and desire to secure by Letters Patent, is-

1. In a lock for fire arms the combination with the hammer, of the sear having a hammer retaining projection and provided with an arm having a projection lying normally in the path of the striking part of the hammer, substantially as described.

2. In a lock for fire arms, the combination with the hammer, of a scar having a portion for engaging said hammer and holding it in cocked position and a forwardly extending part provided with a safety stop normally in the path of the striking part of the hammer and means for operating the sear to release the hammer and withdraw said stop, substantially as described.

In testimony whereof I aftix my signature in presence of two witnesses.

GEORGE A. HORNE.
