UNITED STATES PATENT @trice CHARLES OSBORNE ELlilS AND EDVARD VILLIAM VILKINSON, OF BIR- MINGHAM, ENGLAND.

JECTOR MECHANISIVI FOR BREECH-LOADING FIRE-ARMS.

SPECIFICATION forming part of Letters Patent No. 394,843, dated December 18', 1888.

Application filed January 27, 1888. Serial No. 262,173.

To @ZZ whom, it may concern.-

Beit known that we, CHARLES OSBORNE Y ELLIs and EDWARD WILLIAM WILKINSON,

gun-manufacturers, subjects ot the Queen of Great Britain, residing at Birmingham, England, have invented certain new and useful Improvements in Ej ector Mechanism for Breech-Loading Small-Arms, (for which we have applied for Letters Patent in Great Britain, numbered 7,222, dated May 1S, 1887 g) 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 for hammerless breechloading small-arms of the kind commonly called drop-down guns. p

Figure l represents, partly in vertical section and partly in elevation, a breech-loading drop-down hanimerless gun provided with ejector mechanism constructed according to our said invention, and which said view represents the gun cocked and with the parts in the positions which they assume when t-he gun is ready to be discharged. Fig. 2 shows a like view as Fig. l, but with the gun discharged. Fig. 3 represents the gun partially7 opened and just before the ejector-slide is liberated, and also before the `tumbler is at full-cock. Fig. 4 represents a like view as Fig. 3, but with the barrels fully opened and the gun cocked. This said view, Fig. 4, also shows the ejector liberated and a cartridge-case in the act of being expelledirom a barrel. Fig. 5 shows one-half of the split extractor and rod, partly in section. Fig. 6 is the ejectorsear. Fig. 7 is the ejector-slide with the rear part in section. Fig. S is a plan of the spring, showing the stud upon its side, which works a slide to and fro, on t-he said spring being lengthened or shortened, by compressing and opening out. Fig. 9 shows a side elevation of the said spring and slide. Fig. l0 is acentral longitudinal section of a Inodiiied con- -struction of the gun with the barrels partly opened. Fig. ll is a sectional view of same modiiication, showing the barrels fully opened and a spent cartridge-case in the act of being irted from one of them.

(No model.)

Patented in England May 18, 1887, No. 7,222.

The same letters oi' reference indicate corresponding parts in Figs. l to 9, both inclusive, ot' the drawin a o are the barrels, and Z1 is the body, of the gun.

b2 is the face ot the break-olf, and a2 are the breech ends ot' the barrels, fitted with divided or split extractor-rods c2-that is, the rods c2 are half-round or made from a rod divided longitudinally about its middle, and which said half-round rods are gapped at c3, wherein the arm or snug yL' works for the sliding in and out of the extractor-halves. The said extractor-rods, which work through the solid metal on the under sides of the barrels, have their front ends exposed, and against which said front ends upwardlyextended rearends, d2, ol' ejector-slides d respectively take their bearings or abutments.

The ejector-slides d have guide-stems d3, which work through holes in' depending brackets e3, carried upon the under side of the fore-end iron e2 of the fore end e. The rear parts ot these stems are slotted and shouldered at d C17, against the latter of which the back ends of coiled springs d4, encircling the stems dtake their abutments,with their front ends pressing against the back of the hanging brackets e3. The lower part of the back ends of the ejector-slides have bents or notches di, wherein the nose ends f2 of swinging ejector-sears f engage respectively, and at the rear ends of these sears are overhanging step-like projections f3, and when the sears are in the position as in Fig. l theyrespectively come in front of and above juttingont extensions j? on the front curved faces of reciprocating slides j, which are moved to and fro, so as to bring the extension ,7'2 in front of the projection f3 of the scar f through the intervention ot the mainsprings on, whose fore parts carry snugs or studs m2, which work within gaps jg in the slides j.

The free end m3 of the stand side of the spring works within a seat, 7a2, at the junction of the breast with the foot of the tumbler, so that as the tumbler oscillates upon its jointcenter l# on being discharged or thrown forward the sp1-ings are made to slide forward and carry with them the slides j, but on the cooking of the hammer the springs are moved IOO in the reverse direction and leave behind them the slides, which are pressed back after the releasing of the ejector-scar by the rear part, f4, of the swinging ejector-Sear, which is hung upon the j oint-pin f 6, coming again st the extension j?, as is represented in Figs. 3 and 4.

The ejector-scar is kept up to its work by springs f5 acting upon side' shoulders, f7, while the slides are kept in their respective backward and forward positions by springs g3 working upon the two opposite sides of the hanging V ends jl, as it will be seen that the toes of the springs are inclined, so that on the slides being worked to and fro the springs are moved out of the way, and the said slides retained by the said toes of the springs coming upon the respective inclines of the part jl.

0 is the scar proper, and s is the cartridgecase lying within the chamber of the barrels.

The ejector mechanisms are operated as follows, and as they are in duplicate with the cooking mechanism we will only describe one of them.

On the firing of the arm, as in Fig. l, the tumbler k in falling urges forward the spring m and presses the slide j into the position as represented in Fig. 2, and held there by the foot end g4 of the spring g5 coming against the back side of the hanging V part ji. The moving forward of the slide is done by the stud m2 on the fore part of the spring abutting against the solid metal at the back of the gapped hole js in the said slide. By this change of position of the slide the extended shoulder part "2 is brought under the proj ection f3 at the rear of the hanging scar j', so that on the breaking of the barrels, as hereinafter described, the ejector-scar is automatically released. It must also be observed that prior to the discharge of the arm the ejector-slide d has been pushed back and the spring compressed, as in Figs. l and 2, by the movement forward of the extractor-rod c2 of.

the extractor c on the closing of the arm, and which slide is held by the ej ector-scar nose f 2 engaging with the bent d5. To open the barrels, turn the lever aside, when the bolts are withdrawn and the barrels fall, as in Fig. 4E. The falling of the barrels causes the proj ection f3 of the scar to come against the extending shoulder mi2 of the slide, and so turn the nose of the said ejector-scar forward in the direction as indicated by the arrow, thereby suddenly taking the said sear-nose from out of the bent d5 of the ejector-slide (Z, and so liberates the said slide, which strikes the front ends of the ejector-rod c2 and shoots forward the extractor with considerable force and velocity. The shooting forward of the extractor and extractor-rod (which has been previously drawn out to its extracting position) flirts or expels a cartridge-case, s, from the barrel fired, leaving the other and nndischarged cartridge within the other barrel. rlhus the sudden release of the ejector-slide by the lifting of the rear of the ejector-scar takes the nose of the said sear from out of the bent ornotch in the slide, which on being released exerts a sudden impetus upon one-half of the extractor, thereby expelling a cartridge-case from the barrel iired.

The arm is cocked in the usual manner.

Fig. l0 represents a modification of our invention, in which the slide j is reciprocated or moved to and fro entirely through the influence of the spring m., In this modified form of the slide the stud m2 of the spring takes behind a fork, jg, so that on lthe spring being reciprocated by the oscillation of the tumbler the slide is moved into and out of position, by means of which the ejector-scar is operated on the breaking of the barrels.

The other parts are the same, and are indicated by corresponding letters of reference, as in the preceding figures. In Fig. l() the barrels are shown partly opened, while in Fig. ll they are shown fully opened, and la spent-cartridge case shown in the act of being liirted from one of them.

Having thus described this invention, we claim as new and desire to secure by Letters Patentl. In a hammerless breech-loading gun, the combination, with the internal hammer, k, having notch 7a2, spring m, and stud 'm2, attached thereto, of slide j jzj j, extractor-Sear f, spring f2, and slide d3, having encircling spring d4 and rod c2, said slide being between the spring m and the sear f and below the extractor-rod 02,'substantially as shown and described. r
