Application filed flctober 10, 1927, SeriaI I To. 225,158, and in'France November 3,1926r The present invention relates to improvements in fire-arms with stationary barrels, and the improved fire-armssmay be constructed as, army rifle, foWling-piece or light gun of the single-barrelled or double-ban relled type.

One feature of the invention consists which is slidable in guides upon a stationary plate.

A further characteristic of the invention consists in the means employed for the lock-. ing or fastening of the gun, which comprise one or more movable heads provided with threaded sectors coasting with like threaded sectors disposed in the respectiveboresof the socket piece, said movable heads being disposed in the said movable block and thus moving with the latter.

Another characteristic consists in the fact that all parts of the fastening device'and the percussion device are disposed in the. interior of the gun, either in-the said movable block or in the bottom plate,'whereby'the gun will be perfectly smooth-on the exterior, without projecting parts.

Further 'ChEI-IELCtGITIStlCS of the invention will be specified-in the following description with reference to the appended drawings? which are given solely byway of example,

relating to a double-barrelled' gun according.

to the invention.

F ig. leis, a side view of amovable head comprised inv said modified construction.

As observed in the apparatus shownin Figs. 1 to 9, the gun accordingto theinvention comprises six essential parts: (althe gun tubes andtneir assembling socket piece,

(b) the base plate, (0') the movable block,- (cl) the bottomv plate, (6) thewood portion,

(f) the metal fittings.

The gun tubes 1 and12 are screwed into the assembling socket 3, and theyare connected together throughout their whole length by. 1 the middle strip 4 (Figs. 1 and 7). The two bores of the socket 3 corresponding to. the

two barrels l and Q'carry threerespectivescrewthreaded sectors 5, 6 in the interior,

and each sector covers of the internal cir- A. recess 7- cumference ofthe said bores. which is formed between thetwo bores and at the lower part ofthe-said socket, serves to contain the extractor: 8. The .saidsocket carries at the lower part a boss 9 engaging. a corresponding recess 14 formed in the base plate 11; into the'said boss is inserted'the screw 12 which secures the said socket to the plate 11, said screw being operated by means 7 of the lever 13. A rib which is formed below the said socket and upon its entire length I serves to secure the proper direction of e guns relatively to the plate 11 when tile parts are assembled.

socket 3, as well as the rib which is formed below the said socket for the proper mount-v Fig. 13 is .a cross-sectionon the line ;1 3.l3?

ing of the barrels. Upon the upper face of the plate 11 are provided two lateral slots 15 (Fig. 6) which serve as guides for the movable block. Suitable apertures are also provided for the insertion of the hammers 16 and 17. A downwardly extending front portion 18 serves for the insertion of the front end of the bottom plate 19. At the rear end of the said plate is formed the tapped hole coacting with the assembling screw 20.

The movable block or breech block comprises the main part 21 having at the bottom a T-shaped portion 22. (Fig. 4) which is slidable in the plate 11. I

At the front part of the block 21 are formed two cylindrical recesses adapted for the insertion of the respective shanks 23 of the movable heads 24 (Figs. 8 and 9) which are adapted to enter the respective apertures in the socket 3. r

Into a recess formed in the block 21 is inserted the member 25-which controls the r0 tation of the said movable heads. The middle part of the said block is cut out upon its entire height to aiford passage to the device actuating the member 25 and also to allow the motion of the hammers 16 and 17. At the upper part of the block 21 are formed two flat parts 26 in which engage the lugs of the lever 27 actuating the mechanism.

The shanks 23 of the said movable heads are rotatable in their reoesses but are held against lengthwise motion; for this purpose they are respectively provided with a stud 28 which is slidable in an annular groove formed in the respective recesses. In each of the said shanks is formed a fastening ramp 29. The movable heads 24 carry threaded sectors 30 coacting with the like sectors of the socket 3. At the rear end of each shank 23 is formed a slot 31 termed safety slot, in which is engaged the corresponding hammer which thus strikes against the striker 32, for the firing position.

In the contrary case, i. e. should the r0tation of the movable heads in the socket 3 be incomplete, each slot will have an inclined position, and this will prevent the respective 33 (Fig. 4) engaging the fastening ramps 29 of the shanks 23; said trunnions also limit the lengthwise motion of the strikers 32 in the movable heads, and for this purpose each striker has a restricted part as shown in Fig. 2.

guiding slots 15 of the.

the 7 At the front part of the member 25 is formed the lower projection 34 which serves as an abutment for the spring 35 which is contained in a recess in the block 21 and which urges the said member 25 towards the front.

The longitudinal motion of the member 25 is controlled by a jointed device which comprises a link 36 pivotally mounted at 37 in a forked portion of the member 25 and at 38 upon the controlling lever 27; said lever is pivoted about a pin 39 secured to the movable block 21 and comprises a long arm whose end is provided with lugs coacting with the flat parts 26, and also a short arm 40 whose outer end carries aroller 41 which during the whole of the opening and closing strokes of the block 21 will slide upon the plate 11 and will thus prevent the lever 27 from descending; it can only descend when the roller 41 can enter a recess in the said plate. Since the spring 35 urges the member 25 forwardly, the said controlling lever will operate in an.

approved manner during its entire stroke.

It will be observed that the pivotation of the lever 27, by moving the member 25 lengthwise, will actdue to the trunnions 331 engaged in the ramps 29t0 effect the rotation of the said movable heads; said rampsare so disposed that this rotation will take place over revolution, and in this manner the sectors 30 of each movable head will come into engagement with the corresponding sec only when the block 21 is in the closing posi-- tion.

The extractor 8 which is slidable in the plate 11 is drawn along with the movable block 21 by means of a projection 42 on the bottom of the block, and this also limits the opening stroke of said block, by the use of an abutment (not shown) formed on the plate 11; said abutment also limits the motion of the extractor during the opening movement.

The bottom plate 19, whose front projection engages the vertical part 18 of the base plate, and which is secured at the other end by the assembling screw 20, comprises two lateral cheeksjbelow the bottom plate 19 is riveted the how 43 which protects the triggers 44 and 45, the latter being engaged in suitwith the forwardly-situated cocking portion "50', and therearwardly situatedflat portion coactingwiththetrigger spring-52. 'Herein aremounted 'on' the axle 4:6;andare cooked "in the overturned position" of the'hammers 16 and'17 (Figs: 1 and 2). "The saidhamcartridgeishells that may be accidentally .out

mersare released by pulling the saidtriggers soas to disengage-theabutments 49 fromthe ends 50.

"The safety device com-prises the-lever I 53 secured to-the cam 54; said lever is disposed on oneside of the gun, and when itis turned about it will hold thecentr'al parts of the hammers. A suitablespring 55 serves to'se- 'curethe mechanism inthe firing position or in the safety position.

The'wood' portion ofthe gun is made in twofpieces, i. e.the gun stock'which is held by assembling screws,-andthe front piece which i is screwed to the bottom ofthe plate 11.

-Let it besupposed'thatthe shot has been "fired. The gun is opened by raising the opturn the movable heads through revolu-' tion; as above stated. The'sectors'30 of said crating lever 27 the member 25 which is connected-with the-saidlever by the link 36 will be thus moved to the rear, and will T heads-willthus be released from the corre- "able heads.

block 21 isthus enabled toslide-totherear of the plate 11 and draws with it the said movaxle into the cocked position', the "trigger springs being thus compressed.

'At a certain point on itsstroke, the extractor 8- which is drawn bythe projection 42 *banelsQ-ahd the said movable-block'21iis moved forwardly by the-lever 27 until the said movable heads made contact with the ends of the cartridge. The'roller 41 may now -engagethe corresponding slot in the plate 11,

and the lever 27 can'then be lowered,-as above stated. Due to this motion, the member 25 7 rotates the movable heads whose threaded sectors 30" now engage thelike-sectors of the socket 3. The gun is thus closedand fastened" when thelever 27is completely-low ered.

To holdthe movableheads against rotation' duringthe motion ofthe block 21' upon the base plate, the} lower tenons of the said heads preferably comprise a: very long bevelle d part (not shown) andwhenthegun is displaced 'relativelyto the movable heads,

openedfithis "part *makescontact with the in-the interior of the socket 103. In this-motion of th block 21 123 comprises, as before, asafety slot 131..

the hammers 16'17 are'overturned on their plate 11, so that the movable heads will be prevented from rotating.

The. engagement of theroller 41in the cor responding. slot in theplate 11 will preferably take place somewhat before'the complete engagement of the movable heads in'the socket 13, so that the lever 27 can be lowered somewhat sooner,-and in this manner any ofzthe of shape can however be moved forward. in

' the gun barrels; to this end, the fastening ramps 29 of the shanks 23 of saidheads comprise a straight part, as shown in Fig.- 8.

"Obviously,the invention is not limited to the above described construction which may be variously modified Without departing from the. principle ofthe invention. I

For instance, the gun may be obviously constructed as a. single-barrelled igun.

Figs. 10 to 1 1 relate'to a modification which differs from the one represented in F gs. 1 to Qchiefly in the construction ofthe fastening mechanism. The movable block 121 is made hollow in the interior for the insertion of the and tothis end=they are each provided with a helical fastening ramp 129 in which is permanently engaged a stud 133'screwed into the block 121. 'Each stud 133 limits theinoti'on 'ofthe corresponding striker 132 which comprises for this purpose a restricted part Fig. 11). The heads 124 are provided with threaded sectors 130 coacting with like sectors Each shank At the respective sides of the block 121 are disposed the striated buttons lath-157 which are mounted on the ends of the respective horizontal studs 158159,'these being outstops'engage'the guiding slots 115 of the base plate 111 and thus hold the block 121 upon the said plate. This locking device serves to prevent 'all separation of the element 121 from thesocket piece under'the erlect of'jarring.

The movable block can be released, so that it may slide upon the plate 111, by pushing in the buttons 156-157, thus releasing the stops 161 1.62 from their recesses.

' The operationofthe said fastening mechanism is as follows:

'During the motion of the block 121 for closing purposes, the movable heads which are drawn with the said block will be engaged in the socket piece 103; the sectors 130. will be engaged inthespa-ces between the sectors 'of'said socket piece. At thistime,,the said block beingstill pushed forward, it will-be and the latter, due to the studs 133 engaged in the fastening ramps, will turn in their respective bores, and the locking is effected, while at the same time the stops 161-162 will hold the said movable block.

For unlocking the buttons 156-157 are first pushed in so as to release the movable block 121, and this latter is then brought to the rear. The heads 124 will turn soas to release the sectors from the socket piece, and are then drawn back along with the movable block.

The said modification is applicable with equal facility to single-barrelled or' double barrelled guns, but it is particularly adapted for the single-barrelled type, in which but little force need be exercised upon the movable block for the insertion of the cartridge or the removal ofthe shell, even should the shells be out of shape.

The mechanism comprising the control le- 7 ver 27 shown in Figs. 1 to 9, is chiefly applicable to double-barrelled guns, in which a greater force is required for the insertion or removal of the two cartridges (or shells) than in the case of a single cartridge, and especially where the shells are out of shape, as above mentioned.
