COOKING MECHANISM FOR GUNS.

Specification of Letters Patent.

Patented Sept. 3, 1907.

Application filed April 2, 1898- Serial No. 676,180.

To all whom it may concern:

Be it known that 1, CHARLES F. LEFEVER, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Cooking Mechanism for Guns, of which the following, taken in connection with the accompanying drawing, is a full, clear, and eXact description.

My invention relates to cocking mechanism for breech-loading guns, and the object thereof is to provide such mechanism which is particularly simple in construction, economical in manufacture, and efficient and durable in use.

To this end, the invention comprises the parts, and the combinations and arrangements of component parts to be hereinafter described and particularly pointed out in the claims.

The invention is susceptible of various embodiments, but for the purpose of clearly disclosing the same, I have illustrated in the accompanying drawings, and shall hereinafter describe in connection therewith, what is now conceived to be a preferable embodiment.

In these drawings-Figures 1 and 2 are elevations, partly in section, of a portion of a gun equipped with my cocking mechanism, the barrels being shown in their normal positions in Fig. 1, and as broken or dropped in Fig. 2. Fig. 3 is an elevation, partly in section, of the portion of a gun seen in the preceding figures, the fore-end being removed, and the barrels being shown in the position assumed when about to be disconnected from the breech. Fig. 4 is an inverted plan view of the rear ends of the gun-barrels seen in the preceding figures. Fig. 5 is an isometric view of the hammers and cocking lever detached from the other mechanism of the gun.

My cocking mechanism includes generally a cocking lever A, associated with the hammer or hammers a of the gun, engaging means B associated with the barrel or barrels b of the gun, and engaging means associated with, or constituting a part of, the cocking lever coacting with the means B. The cocking lever A is usually connected to the hammers a with a lost motion, being here illustrated as having its rear end fixed to the hammer-pivotal pin a, which is provided with feathers or keys 0}, movable in key-ways or grooves a in the journal-openings of said hammers.

My invention contemplates the provision of means associated with the hammer or hammers and cooperating with the means B for cocking the hammers during the dropping of the barrels and for arresting the drop thereof, which means is separable from the means B while the hammers are in their uncooked or cocked position, and when the barrels are in a substantially closed position, so that by a slight endwise movement of the latter they may be detached from the breech.

A further object contemplated is a construction in which an increasing leverage is obtained for cocking the hammers as the barrels attain the limit of their breaking or dropping movement for the purpose of compensating for the increasing tension of the main springs of the hammers.

The engaging means associated with the hammers, contemplated by the invention preferably includes an elongated bearing surface normally located above and substantially in front of the means B and unobstructed at one end, and a second surface or abutment at the opposite end of the first surface and disposed at an angle thereto for the purpose of arresting the travel or slidable movement of the element B along said elongated surface, as will hereinafter appear. The element B preferably occupies a position in close proximity to the unobstructed end of the first surface when the barrels are in substantially closed position, so that by a slight endwise movement of the latter the element B may be entirely disengaged from said surface. Said element B is here shown as a shoulder projecting from the inner faces of a groove 11 which is formed in the barrel-lug b and receives the free end of the cocking lever.

In the particular embodiment of the invention illustrated in the drawings, the elongated surface slid-ably engaged by the element B to effect the cocking of the hammers is provided by the underside a of the bill of a hook formed integral with the cocking lever A, and the second surface or abutment is provided by the inner side of the bail a of the hook or the portion joining the bill to the main body, said hook forming a rigid extension of the cocking lever. As will be noted, the space between the body and the bill constitutes a slot at in which the element B is guided; this slot having its front end closed to arrest the movement of the element B, and its rear end unobstructed and opening through the upper face of the lever A to permit the element B to pass entirely out of said slot. As will be appreciated, in the breaking or dropping of the barrels, the element B travels from its normal resting point, toward the closed end of the slot, thus gradually increasing the leverage of the cocking lever A as the tension of the hammer-springs is increased. and when the element B abuts against the second surface the further dropping of-the barrels is arrested. It will be understood, however, that before the element B comes into engagement with the second surface or abutment, the hammers a are engaged by suitable sears a, which act in the well known manner for holding the hammers in their cocked positions. When the barrels are being closed, the element B travels along the surface a and as said barrels reach the limit of their closing movement, the element B substantially passes from beneath the surface a which, even when the hammers are uncooked, is arranged out of the path in which the element B is movable with the barrels during the detachment and replacement of the barrels. The barrels b, as here shown, are so connected to the breech of the gun that when the fore-end b is removed and the barrels slightly broken, as illustrated in Fig. 3, they may have a limited endwise movement rearwardly, in order that the element 13 may be entirely disengaged from the elongated surface, or moved entirely out of the slot at, thus freeing the barrels so as to permit upward movement of the rear ends of the same independently oi the cockinglever, and the subsequent detachment of the barrels from the breech.

In the illustrated embodiment of the invention, a double-barreled gun is shown, and the invention has been described particularly in connection therewith, but it is obvious that my mechanism is equally applicable in a single-barreled gun.

The construction and operation of my cocking mechanism will be readily understood upon reference to the foregoing description and accompanying drawings, and it will be apparent that considerable change may be made in the details of construction and arrangement of the component parts. without departing from the spirit of the invention.
