IMPROVEMENT IN i.BREE'CH-LQADING FIRE-ARMS.

lSpeciicrwon forming part of Letters `Patent N o.l22,470, dated January 2, 1872'.

To all 'whom itmay concer/:L: l

Be it known that I, JAMES LEE, of Milwaukoe, in the county ,of Milwaukeeand State of d through so lunch of a breech-loading tire-arm as will illustrate my invention. Fig. 2 represents a vertical cross-section through the saine. Fig. 3 represents the breech-block in perspective and detached from the arm. Fig. 4 represents in perspective a band for holding the barrel of the arm to the stock, which is without a swivel, but a'ords a fastening for the strap b v which the arm is swung to the shoulder. Fig. 5 represents a portion ot' the stock of the arm, with the band in section theron;

Similar letters of reference Where they `occur in the separate figures denote like parts ofthe {ire-arm in the drawing.

My invention relates, first, to a cartridgeextractor, which is started by a shoulder on the hub of the breech-block taking against a shoulder near the top of said extractor, and then suddenlyT accelerated inits movementby the under side of the breechblock strikin g the tail of the extractor, which gives the head and longer part thereof a sudden and qhick motion to throw out the empty case. The invenltion further relates to a. trigger-lock, which is moved in the under point ot' the trigger by the breech-block whenswung-back, and which is readilypushed back again by the trigger when the breech-block is swung up and forward to close the bore of the arm, or in the act of ring the arm. To enable others skilled in the art to make and use my inventioin'l will proceed to describe the same with reference to the drawing. A represents the frame of the arm, to which the breech-block B is hung by the pivot-pin C. On the hub or central portion of the breechblock is formed a recess, b, terminating ata shoulder, 0. On the inside o1' the frame and between the breech-block and frame is hung l on a pivot-pin, d, the cartridge-extractor 1),

block in being swung back strikes the tail-end of said extractor, which, by the diiierence in length ot' the leverage oi' the extractor each side of its center of motion, gives the heador upperend a quick and sudden and extended movement, by which the shell is thrown clear .out ot' thel arm. When the tail ofthe extractor is thus struck the projection j' on its upper portion moves freely through the recess b, there heilig nothing' to impede its motion.

I have said'that the extractor was placed between the breech-block and the frame. Itis so in one sense of that termgbut in ,reality the breech-block is out away, so that theextractor works in that cut-away portion, and so that its projection j' may be caught by the shoulder 0n the guard-strap E, on the inside thereof, is arranged a sliding lock, g, which has an upright arm, h, upon it that is struck by the breech-bloclt,wl1en said breech-block is swung back, and by said breech-block the end g of said` lock is moved under the pointioit the trigger F, and prevents the trigger when the breech-block is in this` position from tripping the lialnlneiaiid allowing it to iiy. W hen, however, the breech-block is swung up to close the Mbore ofthe arm, then the lock g isiree to, be moved out ot; the way'when the point of the trigger comes against it, and is no impediment to thc tripping of the hammer and.` letting' it ily. But when the chamber isA open and the breechlblock is down this cannot be done, as the trigger cannot then move farenough to release its point from the hammernotch, and thus an accidental touch of the trigger can do no harm to the user. To the guardstrap is also fastened, as at j, a spring, lc, the

forward end of which bears against the breecbblock to hold it up in its closed position, andthe rear end of which serves as the trigger spring,

thus makingone spring' serve the two purposes of a breech-blo'i-k and of a trigger spring, G is a band for holdin g the stock to the barrel.`

This band though having no swivel affords an i Having thus fully described my inventon,vl l
