GEORGE A. HORNE, OF SYRACUSE, NEV YORK.

SPECIFIOATIONformng part of Letters Patent No. 528,228, dated October 30, 1894.

Application filed July 10, 1894. Serial No. 517,103. (No model.)

To all whom, it may concern: y

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 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 breech loading hammerless guns and consists in the novel features of construction and combination of parts hereinafter described reference being had to the accompanying drawings which illustrate two forms in which I have contemplated embodying my invention and said invention is fully disclosed in the following description and claims:

The object of my invention is to provide a simple and efficient ejector for the cartridge 4shells which will be operated positively to force the shell outwardly for a short distance and then be given a sharp quick movement which will eject the shell completely from the gun.

Referring to the said drawings, Figure 1 is a view partly in section illustrating aportion of the breech and barrel of a single barreled gun embodying my invention. Figs. 2and 3 are detail sectional views showing the shell ejecting mechanism in dierent positions. Fig. 4 is an enlarged detail view of a portion of the ejecting mechanism. Fig. 5 is atransverse sectional view of the barrel through the ejecting mechanism. Fig. 6 is a view showing the end of the barrel in elevation I desire it understood that they may be applied to a double barreled gun if desired.

In the drawings, A represents the stock portion of the gun and B represents the barrel provided with the coupling lug b for engaging the coupling bolt d secured in the forward end of the frame A.v

C represents the hammer pivoted at c and provided with a firing point or projection c'.

D indicates a combined scar and trigger pivoted at d having an arm d for engaging a shoulder c2 on the lower end of the hammer for holdingit in cocked position, and a finger piece d2 for tripping the sear.

E represents a locking plate sliding in ways or grooves a c formed in the sides of the lock casing and adapted to enter anotch b in the rear edge of the barrel lug b to lock the barrel in its normal or operative position.

The plate E is provided with a central slot or opening as shown in' Fig. 9 through which the hammer C projects and the forward edge c of this opening forms a shoulder adapted to engage a lug or projection c8 on the hammer to cock the same when the locking plate E is moved rearwardly to unlock the barrel as shown in Fig. 1. I therefore prefer to term the forward edge c of the recess the cooking shoulder.

The plate E is retracted by means of an eccentrically located pin f on the bottom of a vertically rotary bolt F supported in the lock casing and having an unlocking lever f on the upper edge of the stock outside of the lock casing for rotating said bolt to retract the locking plate. The pin f engages a slot e2 in the locking plate to move said plate rearwardly. In order to prevent the bolt F from rising it is provided with an annular groove f2 which is engaged by a pin f3 passing transversely through the lock casing.

G represents the main spring for the hammer C. In using the above described construction it will be seen that by turning the lever f to rotate the bolt F the locking plate E will be drawn back to cock the hammer C and release the notch b of the barrel lug so that the breech may be opened to load the gun.

In Figs. 10 and 11 I have illustrated a slightly modied construction, in which all the parts previously described are the same with the exception of the barrel lug and the lookin g plate E. The locking plate E is in this instance provided with a slot e3 to be engaged by the pin f of the bolt F, a slot or aperture e4 for the passage of the hammer C and a larger slot or passage e5 for the passage of the rear portion of the barrel lug which is separated from the front portion of the lug in this instance by an inclined open slot b2 having at the top a horizontal forwardly extending recess b3 which is engaged by the forward end e6 of the plate E. The forward edge b4 of the slot b2 is a cam face adapted to engage the forward edge e6 of the plate E when the breech is opened, and thereby force said plate E rearwardly until the forward edge c7 or cocking shoulder of the plate cocks the hammer C. It will be seen by reference to Fig. 10 that by turning the lever f the plate E will be drawn rearwardly far enough to withdraw the plate from the locking notch b of the lug and the forward end e6 of the plate from the horizontal recess b3 at the upper end of the slot b2. When the breech is opened by swinging the muzzle of the barrel downward the cam face b4 will engage the end e6 of the plate and move it rearwardly thereby cooking the hammer. The rear face of the slot b2 is concentric with the face b4 and will therefore return the plate to its original position when the breech is closed.

I may employ a spring for insuring the prompt return of the plate E and its connected parts both in this form and in the form shown in Figs. 1, 8 and 9 if desired. I also provide an improved shell ejecting mechanism which is shown particularly in Figs. 2, 3, 4, 5 and 7.

A tubular passage bx is hollowed out in the upper part of the barrel lug b adjacent to the barrel bore and in this passage is located an ejector sleeve H shown in detail in Fig. 7. Through the ejector sleeve and through the entire length of the passage bX passes the extractor slide Zt having its outer end provided with the usual extractor h. The forward end of the passage bx is reduced as ,shown forming an annular shoulder h2 between which and the sleeve H is located a powerful spring H', which when the sleeve is released, throws the sleeve into engagement with the extractor and ejects the shell. The sleeve H is provided with a slot h3, see Figs. 5 and 7 into which projects a pin h4 to hold said sleeve against rotation and to keep it from being forced out too far by its spring and another pin k7 passes from the opposite side of the barrel through a similar slot in the sleeve H and into a groove in the extractor slide to hold it in the same manner.

The forward end of the extractor rod h is adapted to engage a shoulder B on a part connected with the frame A when the breech is opened, to start the cartridge shell by a f positive movement and during this movement I prefer to hold the extractor sleeve out of operation. To this end I employ a spring actuated stud or detent L movable vertically in a passage formed in the barrel lug pressed upwardly by a spring Z held in position by a screw plug Z', the stud L being held from rotation by a pin Z2 (see Fig. 5) or in any other desired way. The upper end of the stud or detent L is provided with a vertical wall or shoulder Zs for engaging the forward edge of a slot hX cut in said sleeve thereby holding the sleeve out of operation. Above the shoulder Z3 the stud isV beveled as shown at Z4 (see Fig. 4) and this beveled portion of the stud extends into a recess h5 cut in the exend in a cam face h5.

By reference to Figs. 1,2, 3 and 4 it will be seen that when the breech is broken the extractor slide h will be forced outa certain distance carrying the shell with it, until as shown in Fig. 2, the cam face h? of the extractor rod engages the cam or inclined portions of the stud H when the further movement of said rod will depress the stud so as to release the ejector sleeve from the shoulder Zs when the spring H will force the said ejector sleeve rearwardly and forcibly eject the shell from the gun. When the breech is again closed the extractor will be forced in carrying with it the ejector sleeve H, the stud L rising and holding the sleeve against operating until again released as before described.

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.

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