To all whom it may concern.

Be it known that I, Dnrmrnios STEReiAN- oPUL'os, a subject of the Kingdom of Greece, residing at 765 Courtland avenue, New York city, New York, have invented certain new and useful Improvements in .Repeating Rifles, of which the following is a clear, full, and exact description.

The object of this invention is to improve the construction of repeat-ing rifles of that class in which the cartridges are heldina rotary magazine within the gun stock, where.l such gun is provided with an ejector mech? anism located along the gun-barrel in front of the trigger, so t-hat manipulating the gun to load, lire and unload, the gunners hand need never bel moved back of the breech in tiring successive shots, and at the same time maintaining all the important features of readyloading, which can be se; cured by a vgun provided with a circular magazine wit-hin the stock. To load such a gun, it is only necessary to have the cartridges in alinementin the clip, then push the entire series of cartridges. into place within t-he stock'.

My invention further relates to various details of construction and arrangement of' parts as hereinafter setl forth, whereby a simple, cheap, readily assembled, easily constructed and readily cleaned gun can be secured.

In carrying out the main object of my inn vention, I provide a spring pressed rotating drum having recessed sides located in a cylindrical chamber in thegun stock in front ofthe trigger mechanism. The breech closer and tiring pin mechanism are mounted to slide together backward and forward across the cylindrical chamber. to close the same at the top'where the cartridges are inserted. This breech closer and liring pin mechanism is reciprocated back and forth by links passing above and across the cylindrical chamber, and the links are operated by a depending handle passing through the slotted forestock of the gun.

The scope of my invention will be pointed out in the claims.

Fig. 15 is a section taken on line 15-15 Fig. 12, after the gun has been fired. Fig. 16 is an enlarged side elevation of the firing pin head. Fig. 17 is a perspective view of the tiring pin latch.

As shown in the drawings, 1 is the forestock, in which the gun barrel 2 is secured in the ordinary manner, 3 is the. trigger protected by the trigger guard 4. The trigger is pivoted at in ears secured to a. plate 6 fast in 'the gun stock. `Within the trigger compartment of the stock is a doublearmed lever 7 forming part of the trigger, and having pivoted to it at 8 and 9 two upwardly eX- tending pins 10 and 11, passing through guides in a metal plate 12 secured on' the upper surface. of the gun stock. These pins upon pulling the trigger are moved, the pin 10 downwardly and the pin l1 upwardly, one unlatching the tiring pin barrel 13, the second unlocking the latch 14, that a spring 15 within the firing pin barrel 13 may roject the firing pin 16 against the cartridge. At the rear of the rifle barrel the breech is formed as indicated in Figs. 10 and 11. At this point the rifle barrel is provided with recesses 17 and 18, the material of the barrel forming shoulders to the rear of the recesses. Between the recesses the ride barrel-is open so that the breech block 19 may be inserted into the breech with the breech locking blocks 20 in position to be rotated into'a position to be locked behind the shoulders just referred to. 'Io secure this rotation of the breech block 19 it is provided with a sleeve 20a fitting into the firing pin barrel 13. The sleeve 20a is formed with a helical groove 21 and With a reduced portion 22. In the-helical groove 21 there is a block 23 fast to the firing pin barrel, so that upon a forward movement of the firing pin barrel and a stoppage of the breech block, the block will .be forced into the pin barrel, and at the same time rotated to lock the breech. In the annular recess 22 a lug 24 on a jaw 25 is located. The jaw 25 consists of a jaw properv 26 which 'is turned over the breech 'block to engage the base and groove of a cartridge for the purposes hereinafter to be described. An arm 27, part of the jaw member,'extends to the rear of the block 24, and is limited in its rearward movement by a pin 28 in the irin pin barrel.

The face o? the breech block has a depressed portion 28 which is normally engaged by a`turned-over end 29 of aslide arm 30, but which is thrown forward upon'the retraction of the firing pin barrel 13 by' reason of its end striking against an upwardly spring pressed pawl 31 fast to the'v gun stock so that the cartridge may be ejected.

Wings or projections 32 ateach side of the firing pin barrel 13 are engaged by hooked ends"33 of long links 34 which pass through the magazine above and to. one side of the cartridges. The'links 34 meet within a longitudinal slot 35 on the gun stock forward 'of the magazine, one link being pivotally fastened by 'a hinge 36 to-a plate 37 to which is pivoted a handle 38. The handle 38 has a spring pressed latch 39 with a lhooked end 40 adapted to engage a notch 41 vin the plate 37 to keep the same yrigid for the hands grasp while shooting but at other times the latch 39 may beunhooked and the handle .swung out of way into the slot 35.

' The firing pin 16 has a shank 42 on'which is mounted a sleeve 43 having a depending lip 44 and a pivoted latch 14. A set nut 45 holds the sleeve in place and serves to adjust-the firing pin 16 in its ring position.`

The latch 14 is provided with a cylindrical lug 46. fitting a bearing in the sleeve 43 and is recessed at 47 for a spring 48 tending to throw the latch 14 into the position of Fig. 10. The firing pin barrel is slotted at its end to permit the ent-rance of the-latch 14 and lip 44 into the firing pin barrel, but

Wings 494.49 at thesides of the latch 14 are adapted to hold the latch in the position of Fig. 10 until elevatedby the pin 11 to aline with properly recessed portions of the sleeve 43 when the spring will project the firing pin. When the trigger 3 is pulled not lonly lis the latch 14 liftedthatit may enter the'iring pin barrel but the pin 10 is lowered to allow the lip 44 to move forward. Also, when the pin barrel is withdrawn rearwardly both latch 14 and lip 44 pass freely over the ends of the pins 10 -and11, but upon closing the breech with a forward movement the lip 44 catches against the pin 10 and holds the sleeve 43 back releasing the wings 49 to cock the gun.

The magazine chamber 50 is closed at the bottom by a plate 51 provided with up rights 52 carrying a freely rotatable drum 53 having a longitudinally fluted surface to form cradles for the cartridges. A spring 54 tends to rotate the drum into-the position of Fig. 8. One long' lip 55 receives the first cartridge to be inserted. The plate 51 has a finger hole 56 through which a slide bar 57 may be moved back and forth. The slide bar 57 carries a pin 58 in its forward end to engage a hole in the forward wall ofthe magazine chamber and two pins 59 at its other end alined with two pins 60 at the end of "a pivoted arm 61. `A spring62 normally holds the arm 61 in the position of Fig. 1, so that upon inserting the plate and drum t-he pins 60 will force the slide bar forward, engage the uprights and cause the forward pin to engage the wall of the chamber..

The gun barrel back of the breech is open at the top and to one side (see Figs. 1 and 2, 6 and 8) and the magazine is closedby the firing pin barrel when `in its forward position. The gun barrel is slotted clear through to allow the cartridges to enter the magazine and is provided with a pair of guide shoulders 63 (Fig. 2) to support and hold one end of a cartridge clip 64 that its cartridges may be quickly and readilyfl inserted into the magazine as shown in Fig.- 8. When the gun has been thus loaded `one cartridge remains above the others as shown in Fig. 6; it may be struck by the breech block and forced into the' rifle bore upon moving the handle 38 forward. A resiliently held plate 65 normally bears against the upper cartridge with s'ufiicient pressure to prevent the ejection of the cartridges in the magazine. A push pin 66, Fig. 3, is provided however to relieve its tension on such cartridge that all cartridges may be expelled if desired. The plate is pivoted at 67 (see Figs.'6 and 8.)

In using the rifle the cartridges in the clip 64 are inserted as shown in Fig. 8 when .pressure on the topmost cartridge will cause vided for it, Figs. 4 and 11, and stops in` its forward movement; the pin barrel eon tinues its forward motion rotating through the stud 23 and helical groove 21 the breech block to lock it in position. The gun has been cocked as before described by the lip esami esbeingheld by thepin l0. VElie trigger is then pulled, the tiring pin passes through the block and strikes the cai dge.` The handle then pulled back, the aws and 29 engaging the cartrii'lge groove and the cartridge is extracted into the open part of the barrel until the endBO of the jaw 25) strikes the pawl 3l when that jaw suddenly stops while the other aw still pulling the cartridge back resulting in a quick snappy eideiifise throw of the cartridge -which expels it lfrom the gun. The next cartridge through effort of the spring pressed drum then comes into a position in front of the breech block for a repetition of the operation.

It will be noted that the gun can be loaded by using a clip in an approved manner andv that all shells may be fired and ejected without taking the hand 'from the handle 38 or lowering the -gun from the shoulder. It

-will also be noted that one motion of the handle 38 places the cartridge in position, locks the breech and sets the tiring mechanisin.
