EJECTOR MECHANISM FOR BREECH=LOADING FIRE=ARMS.

SPECIFICATION forming part of Letters Patent No. 394,844, dated December 18, 1888.

Application filed January 27, 1888. Serial No. 262,174. (No model.) Patented in England May 18, 1887, No. 7,222-

To aZZ whom it may concern.-

Be it known that we, CHARLES OSBORNE ELLIs and EDWARD WILLIAM WILKINSON, gun-manufacturers, subjects of the Queen of Great Britain, residing at Birmingham, England, have invent-ed certain new and useful Improvements in Ejector Mechanism for Breech-Loading Small-Arms, (for which we have applied for Letters Patent in Great Britain, numbered 7,222, dated May 18, 1887;) and we do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form part of this specification.

This invention relates to improvements in ejector mechanism of breech-loading smallarms of the kind commonly called dropdown guns. v

Figure 1 represents, partly in vertical section and partlyin elevation, a breech-loading drop-down hammer gun provided with automatic ejector mechanism constructed according to our said invention, and which said view represents the gun in its normal or fired position. Fig. 2 shows a similar view to Fig. 1, but with the barrels down and the spent-cartridge case ejected. Fig. 3 shows the gun cocked, while Fig. at represents an under side sectional View of the gun, showing the ejectorslides in duplicate and their operating-rods. Fig. 5 shows a part elevation and part section of the under sides of the barrels, thus exhibiting the rod which works the two halves of the divided extractor. Fig. 6 shows an end elevation of the breech ends of the barrels of the gun.

The same letters of reference-indicate corresponding parts in Figs. 1 to 6, both inclusive, of the drawings.

a a are the barrels, and Z) is the body, of the gun.

I) is the face of the break-oft, and a are the breech ends of the barrels, having working andfitting within the face thereof a split or divided extractor, 0, whose rods 0 work within the solid metal of the under sides of the barrels. The forward ends of these rods are exposed, and against these the upwardly-extended ends (I of ejector-slides (1 take their hearings or abutments. These slides cl have guide-stems (1 whose front ends work through holes or eyes made in depending brackets 6 carried upon the under side of the fore-end iron, 9 of the fore-end 6, while the other or rear ends of the said ejector-slides have slots, wherethrough the stems of pins e secured within the fore-end iron, pass. The stems d of the ejector-slides (Z are encircled by coiled springs d whose ends abut against shoulders on the slides and the brackets e respectively. The back ends of the ejector-slides have bents or notches (1 wherein the nose ends f of swinging ejector-sears f engage. The back ends of these sears are also provided with overhanging projections or outstanding parts f and when in the position as in Fig.1 they come above the front ends of the liberatingrods, g, which pass and work obliquely through the body of the arm.

The swinging sears f are hung upon pins or centers f and are kept up to their bents by a flat spring, f whose outer forked ends, re spectively, press upon the rear top sides of the said sears, so as to make them snap into their bents on the slides being moved forward by the ejector-rods on the opening of the arm.

The div'ided extractor and the rods connected to the respective halves are collectively pressed rearwardly by a supplementary rod, 71, working within the under side of the barrels, and with its back end coming against both halves of the extractor, as aforesaid. The rod is worked by the usual arm or snug, 2 (see Fig. 5,) on the joint of the body part, so that on the breaking of the barrels the extractor halves are pressed rearwardly through the intervention of the rod 71.

The sear-releasing rods g are provided at their back ends with slides j, whose rear ends are prolonged upwardly into arms j against which the arms is of rebound-tumblers k on the hammer-axes Z of hammers] come on the gun being discharged by the falling of the said hammers. The tumblers it have full and half cock bents k in and are swivelly connected to the upper limbs, m of mainsprings m by swivelconnections n, and with the standside free ends m of the said springs, taklng IOO upon shoulders at the back of the tumblers, so as to make the lock a rebounding one.

o are sears proper, and 0 are sear-springs.

The searreleasing rods g have doubleneeked parts 9 wherein the free ends of springs g respectively take on the rods being pushed forwardly or rearwardly, as hereinafter described.

1) is the tang-strap of the arm, q is the boltreleasing lever, and r is the nipple, which is shown wit-h the upper portion of the hammer in elevation.

The ejector mechanism operated as fol lows, and as the two sides are alike I will only describe one of them.

On one of the barrels of the gun having been fired, the tumbler 7;, which is upon the hammer-axis, causes the arm 7:? to be urged or turned forward, so as to strike the arm 7' of the slide j, and so force the said slide against the sear-releasing rod g, which is in its turn pressed forward into the position as represented inFig. 1, and held there by the free end of the spring passing into the back annular depression of the double-necked part g This forward movement of the rod brings its nose end 9 under the overhanging projection f of the ejector-sear f, so that on the breaking of the barrels as hereinafter described, the sear is automatically released.

It must be observed that prior to the discharge of the arm the ejector-slide cl has been placed in that position, and the spring d compressed by the forward movement of the extractor-rod of the extractor c on the closing of the arm, and such slide is held in position, as in Fig. 1, ready for cjeetment by the ejector-sear nose f engaging with the bent (1 To open the barrels, turn the lever q aside, when the bolts are withdrawn and the barrels fall, as in Fig. 2. The falling of the barrels, when the parts are in the positions as represented in Fig. 1, causes the nose end g of the rod g, which was under the overhanging p-rojeetion f, to come against the under side of the said projection, and the breaking of the barrels and the dropping of the fore-end with the barrels causes the ejector-sear f to be turned rearwardly upon its hanging fulcrum f, which motion takes its nose end f suddenly from out of the bent (Z of the ejectorslide (Z, and so liberates the ejector-slide, which strikes the front end of the ejector-rod c with considerable impetus, thereby shooting outwardly and rearwardly the extractor, which flirts or expcls the cartridge-case s from the chamber of the barrel, leaving the other and undischarged cartridge within'its chamber, from which it has only been removed to the extracting distance, as effected by the arm or snug i pressing rearwardly the rod 7z-that is, the breaking of the barrels effects the slight extraction of both cases by the rod 71- being den release of the ejector-slide by the lifting of the rear side of the ejector-sear by the nose of the rod protrudingthrough the joint part allows the spring, which was under tension, to expend its released energy upon the slide, thus forcing it rearward with considerable impetus, striking the extractor-rod, which in its turn is suddenly and forcibly kicked backward, and the empty case with the barrel discharged expelled therefrom.

The breaking of the barrels causes the searreleasing rod g] to be pressed backward by the angle formed between the under side of the overhanging project-ion f and the lower back part lying thereunder. In this position the rod is held by the free end of the spring y passing into the front annular groove of the double-necked part 5/ The closing of the arm from the position Fig. :2 to that of Fig. 3 (without the hammer being cocked) causes the extractor end 0 to come against the face of the break-oil b and as the barrels make their angular movement inward the said extractors or extractor-segments are forcibly pressed inward or forward, and with the rods (1- impressing themselves against the ends (P of both of the slides d, thereby pressing back the slide, compressing the spring, and securing the slide in its forward position, as in Fig. l, by the nose f of the sear f engaging within the bent, as aforesaid.

The gun is cocked by hand by pressing back the hammer I, so as to make the sear-nose take the full-cock bent and the arm k of the tumbler 7; into a vertical position, as repre sented in Fig. 3, so that on the arm being dischargedby the pulling off the trigger the cock falls, which causes the tumbler-arm 75* to strike the slide-arm and force forward the sear-releasing rod g into the position as represented at Fig. 1, with the nose end g of the said rod coming under the overhanging projection,which is lifted upward by the said nose end on the breaking of the barrels, as in Fig. 2.

llavin g thus described this invention, we claim as new and desire to secure by Letters Patent-- 1. In a drop-down breech-loading hammer gun, the combination,wilh abody, b, rebounding lock-tumbler 7.: k 7; k 75, and hammer Z, of an. ejeetor-searrelcasing rod, g, and slide j, the rear of which latter is upwardly directed into an arm, and against which the extended top part, 71: of tumbler k presses, and thereby moves the rod forward to engage the ejector-sear on the discharge of the arm, substantially as described and. set forth.

2. The combination, in a hammer gun, of an ejector, ejector-sear, and ejector-sear-releasing rod g, slide 7' j and reboulid-tumbler k, the slide being located between the tumbler k and rod g, substantially as shown and described.
