' s '1 MOVABLE COOKING-SHOULDER FOR BREAKDOWN GUNS.

SPECIFICATION forming part of Letters Patent No. 523,813, dated July 31, 1894 Application filed June 10, 1893- S erial No. 477,177- lNo model.)

To all whom it may concern Be it known that], FRANK A. HOLLENBECK, 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 Breech Loading Hammerless 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.

My invention is an improvement in hammerless breech loading guns and consists in the novel features of construction and combination of parts hereinafter fully described reference being had to the accompanying drawingswhich illustrate one form in which I have contemplated embodying my invenforced into such operative relation when the fore end is applied to the gun.

Referring to the said drawings, Figure 1 is a side elevation, partly in section, of a portion of a firearm embodying my invention showing the rear portion of the barrels and the adjacent portion of the stock, the barrels being shown in elevation. Fig. 2 is a similar View showing the parts in different positions. Fig. 3 is a sectional view of the barrel lug taken longitudinally of the gun showing the position of the cocking plate and push rod therefor. Fig.4is a horizontal section through the barrel lug showing the positions of the hammers and cocking arms with respect thereto. Fig. 5 shows in detail the cocking plate and push rod.

7 Referring to the drawings A represents the stock portion of the gun and B the barrels.

b represents the barrel lug which engages the usual swivel pin or bolt a in the stock. The rear portion of the lug is out away on both sides to form the recesses b b, see Figs.

1, 2 and 4, and a portion of the lower part of the lug is cut away as shown in Fig. 3,1eaving a'shoulder b at the front of the ing. The lug is also provided with a central vertical recess which receives the vertical rib f of what I term the cooking plate, as shown in the drawings, see particularly Fig. 5 where the said cocking plate is shown in detail. The cocking plate consists of a'fiat plate F having the central vertical rib f just referred to, which is provided with slots f to receive pins f which pass transversely through the barrel lug and secure the coupling piece in place but permit it to move in a direction longitudinally of the barrels. The length of the plate F is equal to the distance from the shoulder 12 to the front edge of the lateral recesses b b of the stock and when in this position the pins f will be at the rear extremities of the slot f of the rib f. The plate F can thus be moved rearward so as to bring its rear corners f s f 3 beneath the recesses b as shown in Fig. 2 and these rear corner portions of said plate form what I term cocking shoulders, for cooking the hammers, as will be presently described. The cooking plate is normally held 'in its forward position by means of a spring f located in a recess in the lug b which recess is preferably closed by a screw plug f fitting a screw threaded aperture in the lug, and by means of this construction the tension of the spring may be adjusted as desired. The spring f engages the rearside of a projection j" on the rib f of the cooking plate and the forward side of this projection is engaged by one end of a push rod G located in a suitable recess in the lug, and having one end g projecting from the forward face of the lug in positionto be engaged by the fore end H and pushed rearwardly when the fore end is placed in operative relation with the barrels. The rod Gis held in place by a pin g which engages arecess in the rod and permits the longitudinal movement of the same.

The hammers O G are pivotally mounted in the lock casing on the pin or bolt 0 and each hammer is provided with a cooking arm 0' extending forward into one of the lateral recesses b b of the lug as clearly shown in Fig. 4. The searsD D, main springs E E and triggers K, K, are of ordinary or any preferred construction.

The operation of my invention is as follows: When the parts of the gun are assembled the lug is placed in engagement with the swivel bolt on and the barrels are closed. The spring f holds the cooking plate in its forward ppsition so that the lug will take its lowesLposition in the lug recess of the stock as shown in Fig. 1 without interfering with the cocking arms. The fore end H is then placed in engagement with the barrels and will engage the push rod G and fprce it rearward thus moving the cooking plate rearward so that the cooking shoulders f 5 f of the plateF will be placed beneath the ends of the cooking arms. When the gun is broken to load the cooking shoulders will engage the cooking arms and cook the hammers in the usual manner. To separate the barrels from the stock the fore end is first removed when the spring f will force the cocking plate forward and remove the cooking shoulders from beneath the cooking arms when the parts may be readily separated. I have shown the cocking plate F provided with a finger piece F extending below the lug where it can be reached by the finger to move the cooking plate forward when the fore end is removed. When thisconstruction is employed I may dispense with the spring fif I desire, but I prefer to employ it as it renders the operation 3 5 of the cooking plate more complete. Should the spring break or fail to act the cooking plate can be moved forward to disengage the cooking arms by means of the aforesaid finger piece.

I do not wish 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.

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

In a fire arm the combination with the hammers and theircocking arms, of the barrels, the barrel lug provided at each side with a recess to receive one of said cocking arms, a movable cocking plate consisting of a plate having a rib engaging a slot or recess in the barrel lug, and movably secured therein, said plate having portions adapted to pass beneath said recesses in the lug and engage the cocking arms, a spring engaging the said rib for forcing said plate out of operative relation with the cooking arms, and devices for holding said plate in operative relation with said arms, when the parts of the gun are assembled, substantially as described.

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

FRANK A. HOLLENBEOK. Witnesses:

L. P. WHITAKER, JESSIE KINGSBERY.
