My invention relatesto an impro vement in that class of guns having what are known as balanced breech-blocks, as distinguished from breech-closures positively held in their closed positions, so as to take the thrust of recoil. Balanced breech-blocks as heretofore constructed have been employed in automatic guns and made soas to move back under the thrust of'recoil and in moving back 0 crate the breech mechanism of the gun, a alance being established between the thrust of recoil and the inertia of the mass of the block and the power of the block-closing spring and the power required to open the breech mechanism. In the of my present improvement the breec -block is balanced in the sense that it isnot positivel held in any way to take thethrust of recoi but so adjusted in weight and in the power of its spring to the thrust of recoil as to remain at rest in its closed position at the time the gun is fired.
The object of my invention isto produce a sim le, effective, and durable manually-opera le balanced breech-block gun constructed with particular reference to having the breech-block remain at rest when,the gun is fired and to avoiding that naked and unsightly a pearance which proceeds from having the s iding fore-arm moved forward away from the receiver when the is closed and ready for being fired, as wel as to constructing the sliding fore-arm so as to have the ap-- pearance of an ordinary fixed fore-arm.
With these ends in view my invention consists in a gun having certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.
In carryin out my invention as herem shown I emp 0y a breech-block 2, having a long forward extension 3 made heavy enough in its entire mass, when reinforced by its closing-spring 4, to remain'at rest when the gun is fired. To accomplish thisresult, the block must be made heavier than balanced breech-blocks are generally made or have a closing-s ring of superior power. For the rece tion ofithe spring 4 the extension 3 of the lock is formed with a concentric spring-chamber 5, entered through an opening 6. The forward end of the said spring abuts against a shoulder 7 at the forward end of the said chamber 5, while its rear 'end abuts against the front face 8 of the gun frame or receiver 9. As herein shown the gun is furnished with a tubular magazine 10, having its forward end su ported by the gun-barrel 11 in any of the We l-known ways and having its rear end inserted into a socket 12, formed in the receiver 9, the rear end of this magazine being encircled by the spring 4, for which it forms a guide. The said magazine extends through the fore-arm ti 13, the sliding fore-arm 14, and the breec -bl0ck extension 3, its rear end opening through the breech-block 2 into the inside of the receiver .9 through a feedopening 15-, formed therein. The cartridges when fed out of the opening 15 maybe lifted into position to be loadedintothe gun-barrel 11 by an ordinary pivotalicartridge-carrier or by any other suitable means. This mechanism forms no part of my present invention and is not shown or described. The fore-arm 14, which is suspended, as it were, on the magazine on which it slides back and forth,
is normally retracted or held at the limit of its rearward position with its rear end abutted against the front face of the receiver-9, to the crosssectio'nal-form of which it corres ondsincross sectionahform. Inother wor s,.the sliding forearm.- 14- though functioning as a slidingliandie hasin-rewlitythe-form and appearance of an ordinary-fixed-fore-arm. T e sair'i fbrei-arm' co'acts with the breech-block for manually o ening the same after every timetlie through an operating-levefl l fijjliilng onrapivot 17 passing throughitsvfhrward upper'cornerand mounted in the forearm tii 1%; which is'secured within the mam-ea oftlieforearm'bynieans of two transversely arranged screws 18' 18- or in any otherequivalent' way." The heel 19 of the said-levee 16' is engaged by a spring-plunger 20; mounted in'tlie fore arm tip 13 and'exertmgaf constant effort tof-lift the cam-like rear end-'ofthele'verupward into its operatingpo tl1(-3"08;I11"22f to force the lever downward against the action of the spring plunger' 20 andridezout of thelocking+notch24y when the saidplimger at once reasserts itself and swings the lever 16' so as tolift its rear end into'position to snap intothe coupling ndtch- 21 in-the extension 3 as-soon as-theeontinued forward movement. of thehas broughtthe-notch-into'1egistration the rear end of tlie-l'ever. Now when theifore-- arm is drawn back with the lever so engaged with the breech-block extension the'breechblock 2*wi1l* be'forcd back'into its open'position against thetensiori of its s' ring-4, which will be compressed. Just be re the forearm reaches thelimit ofv its rearward move-' ment the-beveled rear'wall 25 of' thelockingnotch 24 willengage with the front face of the canr22 and the-lever will be forced down- Ward out of the' coupling-notch 21, thus disconnecting the forearm from the breechblock and leaving the s ring 4 free to assertitself todraw the bloc 2 forward into its ing a' bearing slee,v'e23- uponthe magazine 1 0 closed position, in which the said spring holds it, the movement of the block ingoing into its closed position being relied upon to push thefed and lifted'cartridge for-ward'into the gun-barrel. When the fore-arm 14 completes its rearward movement, the cam 22 snaps into the locking-notch 24, whereby the fore-arm is held in its retracted position.
I particularly wish to emphasize the point that under my improved construction when the gun is ready for firing the fore-arm is retracted, giving the gun the externalappearance of'a gun with a fiXBd'fOIG-SIIII.
I claim- 1. Ina firearm, the combination with the receiver and the barrel thereof, of'abreechblock balanced to remain in its closed osition when the gun is fired, a breech-b ockclosing spring, a slidingfore-arm normally located atthe limit of its rearward excursion; and means carried thereby for o erably connectin the fore-armwith tlie reech-block when t 'e'fore-arm is moved to-the limit of its 7 forward excursion.
