SPECIFICATION formin'gi part of Letters Patent No. 478,221, dated July 5", 1892.

Application filed September 6, 1887. Serial No. 248,987. (N model.)

To all whom it may concern:

Be it known that 1, ANDREW BURGESS, a citizen of the United States, residing at Owego, in the county of Tioga and State of New York, have invented certain new and useful Improvements in Magazine-Firearms; and I do declare the following to be afull, 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to breech-loadin g and magazine firearms, having for its object safety and ease of manipulation; and it consists of various arrangements of breech and breechoperating mechanism and combinations of parts hereinafter more fully illustrated and described.

In the drawings, Figure 1 shows a longitudinal section in elevation of the breech of this arm. Fig. 2 is a side view of the breechpiece. Fig. 3 is a longitudinal section of the butt, showing arrangement of the automatic breech-operating device. Fig. 4 is a sectional longitudinal elevation of the breech n1echan-,

Fig. 5 is a cross-.

ism with the breech open. section on the line a: w. of Fig. 1.

Figure of reference 1 is the frame; 2, the bolt; 3, a sliding connection piece to couple the bolt and handle 4, and the rod 5 connects I the breech mechanism with the butt-plate 7 by intermediate lever 6.

The reciprocating bolt 2 carries a pin or trunnion 8 near its front end, which, projectiug into a longitudinal groove or slot 9 in the frame, serves to guide and hold the forward end of the bolt in the frame, and another pin 10 projects from the inside of the frame into a groove or slot 11 of the bolt to guide the rear eiid thereof. The slot 11 is cut longitudinally in the bolt to its rear, where it is carried 11 ward to permit the rear part of the bolt to fa 1 when reaching its closed position,

"as shown in Fig. 1, so thatits shoulder 12 may drop forward of the abutment 13 in the frame,

' and thereby lock the said bolt in its closed position, and the projecting top 14: of thebolt, overhanging the fiat sides thereof, falls on top of the inner edges of the frame to form a tight cover to its vertical mortise.

A bolt arranged as above may be operated by any oblique force which may be brought to bear upon it to turn its rear end from the locking-abutment, and said force, continuing,

will move back the bolt to openthc breech and its reversal will close it. Ishowa method of applying the oblique force described j by projecting an arm 15 downward from thefo'rward end of the bolt and engaging tho'lower end of the said arm by a reciprocating rod or sliding piece 3, to which is connected a handle to impart a reciprocating movement thereto. The backward movement of the piece3 turns the rear end of the bolt upward to' disengage its locking-shoulder, the pin 8 serving as a trunnion or fulcrum to hold theforward end of the bolt down, and then forces back and forward into the slot 11, so that when the rear of the bolt rises itraises the face oflsaid The rear of the firing-pin has incline against the pin 10 (which is iixedin the frame) to cam and start back the firing pin by the unlocking movement of the bolt.

The connectingslide 3 is guided rearward by the operating-handle and a. pin 17,- which enters a longitudinal groove 18 inside the frame. An abutment, which I here show as a roller 19, is carried by the slide 3, and a projection 20 of the hammer is extended into position, as shown in Fig. 1, to be engaged by the backward movement of said roller. which then serves as a cam to turn back the hammer from its position over the ledge 21 in the rearof the bolt, so that the boltmay then be moved back to open the breech. The mortise innthe slide 3 is elongated forward of the bolt extension 15 to permit a slight lost motion for the above operation.

. It will be seen that thenose of the hammer cannot reach the firing-pin until the rear of the bolt falls to its locked position, as the ledge 21 obstructs the path of movement of the striking-nose of the hammer at all other times, and when the bolt isinlocked position ICO free to follow back the opening breech-piece.

The side of the carrier at itsjorward part is cut away to allow the rearward'inove-iiient of the raised ear 23 of the slide; but a shoulder 24. is formedon the carrier to be engaged by the latter part of the rear movement of said car 23 and be raised thereby to raise the carrier,as-shown in Fig. 4.

A handle sliding on the small of the stock is shown'to operate this gun; but any other known form of handle may be substituted without essential change in this invention.

A catch 25 is hungin the operating-handle, having a point 28 to be sprunginto the not b 26 in the guard-strap or any fixed part of the gun to lock the handle when the breech is closed, and thereby confine the breech-piece in its locked position,asin'Fig. l. The catch 25 is here shown provided with a light spring 29,"pressing the catch to turn'it in the reverse or unlocking direction; but a stronger spring 31 turns the starting-lever 30 (which is hungin the sliding handle) downward against the projecting arm 32 of the catch tospring said catch into the notch 26 to lock the handle aforesaid. By this arrangement the catch may be released by pressing in on its projecting. arm 32 or by pressure on the projecting finger-piece of the startingdeyer 30, as in the act of usingsaid lever in starting open the breech, (it having a little lost motion for this purpose of releasing the catcln) when the spring 29 will turn said catch out of the notch 26; but if the handle should be under strong backward pressure the friction of engagement of the point 28 in the notch 26 would be too great to be overcome by the spring 29 and the catohwould remain-in its locking position until released by other means. A starting-rod '5, connected to the sliding handle, extendsabaokward th rough the stock and'is engaged at its rear by one end of lever 6, which is hung on a pivot fixed in the stock, and the telescoping butt-plate 7 engages the other end of the lever 6, so that when the buttplat e moves forward relatively to'the stock it vibrates the lever to force the rod 5 backward and thereby start open the breech-piece by its connection therewith or with the mechanism vfor moving it, and a spring 33 presses the butt-plate, when released, in the opposite direction.

I here show the rod 5 connected to the breeoh-movin g mechanism by having a shoulder 3 formed to engage the projection 27 on the catch 25 above its pivot, so the first part of the backward movement ,of the rod 5- Y1- brates the catch to turn its point 28 out of its locking-notch 26, that the breech or handle may then be free to be moved back by the continued backward movement :of the rod. Another shoulder 35'is shown in Figs. 1 and 4, which on the return (forward) movement of rod 5 engages the point 28 of the catch to close or assist to close the breech by force of spring 33; but where the movement of the I'Od'lS not i made so great as to en able itto move the whole distance necessary to open and close the breech the rear shoulder 35 is oinittedgas in Fig. 3, and the rod 5 then serves merply to unlock and start open the breech.

In Fig. 3 the peculiar features of the butt and its parts are shown. A socket-piece 36 incloses the rear end of the stock and has an inne'r socket 37 to enter the stock and contain the spring 33 and also receive and guide, the cylinder 38 of the butt-plate to hold the buttplate in position to move easily with but slight friction on the outside of the socket-piece 36. 9o Astop,as 40,-consistingofanobliquely-pointed pin or screw, maybe used to con fine'the catch in its locking position when required. Another stop il is shown in Fig. 3' arranged to turn back and render the butt-plate rigid when desired, when the gun may be operated by the handle and the catch 25 turned to unlock the handle by direct engagement or the lever 30 be pressed out ofcontact with the catch by the hand that pulls back on the hanzoo die, and when the discharge then takespla ce the recoilwill counteract the pull on the bandle, giving a backward impulse to the body of the gun so quickly that the pull on the handle will cease for an instant, (in fact, will generally be reversed,) sothat the catch '25 can then be disengaged by spring 29. The interruption to the backward pull on the handle is so short as to be h-a'rd-ly noticeable, except by its effect in unlocking the handle, and r m a continued pull backward on the handle and lever unlocks and opens the breec g To use the butt-plate mechanism, the stop 41 is turned forward, as in Fig.3, and the gun I fired from the shoulder in the usual manner, n5 when the recoil, forcing back the body of the gunv against the resistingbutt-plate, com presses the stiff spring 33 and forces the lever 6 against said plate to turn it and force back the rod 5 (which engages the catch 25) to re- 12o lease and pullback the handle and start back the breech by its connection therewith.

1.- In a breech-loading firearm, a reciprocating breech having a locking-shoulder thereon, 1 25 a lateral projection near the front end of said breech-piece, and a groove from its rear end forward,.said groove being odset at its rear,
