SHELL-EJECTOR FOR FIREARMS.

SPECIFICATION formingpart of Letters Patent No. 624,322, dated May 2, 1899.

Application filed December 15, 1898. Serial No. 699,320. \NO model.)

invention appertains to make and use the same. v

My present invention relates to improvements in the shell-ejector mechanism, the obj ects being to render the mechanism substantial, durable, and efficient for use and economical for manufacture and to provide an ejector mechanism comprising means for primarily positively starting the shell from its seated position, in combination with means for then automatically throwing said shell completely out and away from the chamber,

said mechanism being constructed and organized for operation in the manner more fully hereinafter set forth.

Another object is to provide an automatic ejecting device with a rocking ejector-catchhaving an arm and lug that work in conjunction with a stop-shoulder on the frame for tripping the ejector, as more fully hereinafter explained.

These objects I attain by the mechanism illustrated in the drawings, wherein- Figure l is a sectional view of a gun embodyin g my invention, the parts being shown atthe position occupied after the positive starting of the ejector, but immediately preceding the automatic final ejective action. Fig. 2 is a transverse section through the frame and barrel, showing the form of the ejector-catch and the lug or shoulder foractuating the same. Fig. 3 is a sectional plan showing the top of the ejector and jointscrew mechanisms. Fig. 4 is a side view of the joint-screw arm, and Fig 5 a separate plan view of the ejector-catch and its spring.

In referring to the drawings, A indicates the stock-frame, of suitable or well-known form.

B denotes the barrel, having the j oint-block B fixed on its under side and adapted to fit within the hollow of the frame and hinged or pivoted therein by the joint screw or pin O for breakdown or forwardly-tilting action of the barrel, as illustrated. Said joint-pin 0 passes through and movably fits a transverse hole formed complete within the jointblock 13, near the fore end thereof, said hole coinciding with the openings in the sides of the frame, one of which latter is threaded to receive the screw-thread at the end of the joint-pin when the parts are assembled.

The barrel-catch E and top lever E for operating the same may be of well-known or any suitable construction.

D indicates the ejector-bar, arranged within a longitudinal bore in the joint-block B and having the usual head cl for engaging the rim of the cartridge-shell, also provided with the backwardly pressing spring G, coiled about its spindle portion D within the'bore. Theinner endof the longitudinal bore or ejector-way is disposed at an overlying position in relation to the transverse hole and partially intersected therewith, the top side of the transverse hole being about half-way up in the longitudinal bore. The spring-supporting spindle D can be an integral part of the main bar D or made as a separate piece abutting against the end thereof, as per Fig. 1.

I indicates a rocking catch disposed transversely in the joint-block B beneath the ejector-bar D, which is recessed on its under side and provided at an intermediate position in the top of the recess with an offsetlug n or stop-notch that is engaged by the angle of said rocking catch, the face of which is cut away or flattened, as shown at 3, so that the rocking of the catch-piece will release the ejector. The catch device is secured in the joint-block by acircular nut 4 on one end, and its other end is provided with forwardly and downwardly projecting arm I, that works in a suitable recess formed in the side of the block. The lower end ofthe arm is furnished with a transversely-disposed pin 1", one end of which is pressed by a spring J for keeping the catch normally at interlocked position, while the other end of said pin projects within a recess a, formed in the side of the frame, and acts in conjunction with a horizontal shoulder a at the top of said recess for moving the arm and tripping the catch, thereby releasing the ejector when the barrel is tilted to a given degree or sufficiently to carry the pin i against the shoulder aa slightly greater tilt than that indicated in Fig. 1. The shoulder a has a cut-away space at to .permit separation of the frame and barrel parts when the joint-screw has been removed and the barrel drawn somewhat forward to bring the pin 9; into line with the cut-away.

The joint-screw C is-made with'a recess in the side thereof, forming at its top an upright lug or shoulder r, disposed across the ejectorway and against which the end of the ejectorspindle contacts in such manner that when the rear end of the barrel rises from the recoil-plate to the position indicated in full lines, Fig. 1, the ejector D will be positively forced backward for a short distance and with sufiicient power to start the shell S from the chamber, (see dotted lines, Fig. 1,) overcomin'g any adhesive tendencyor sticking of the shell and partially freeing it from its seat,'so that the resilience of the ejector-spring will meet no excessive resistance in throwing out the shell when the automatic ejector is subsequently brought into action. The jointscrew is'th'readed into one side of the frame at t and i's'provided with an arm C at its head end, theinner side of said arm fitting against theouter side of the frame when 'the screw is set'home. A latch-fingerf is arranged in the slotted end of the arm, pivoted, as at h, and adapted to closedown with its end latching into a nick 5, formed in the frame, as indicated in Fig. 3, for. retaining the joint-screw against any tendency for its unscrewing by reason of the pressure of the ejector on the lug r. The latch-finger f is adapted to'bei swung outward, as indicated by dotted lines, Fig. '3, and there serve as a crank-handle for turningthe joint-screw in and out when desired. The'recess min the ejector-bar forward ofthe offsetnis made of sufficient length to permit this positive movement before the catchI takeselfect on said .oifset. In the operation when the barrel'is unlatched and tilted forward thefirst portion ofthe'tilt movement causes the ejector D to be slowly and positively forced outward by the spindle impinging against the lug r, was

to start the shell from the chamber however firmly itmay be wedged therein. Then as the further tilting movement brings'the-pin i into contact with the shoulder a the catch I is rocked away from the offset n and the spring J automatically drives back the ejector D, easily and effectively ejecting the shell and throwing itfree and clear from the breech of the gun, thus insuring complete ejective action and. obviating any liabilityof the shells sticking in the v chamber with a resistance that would exceed the power of the ejectorspring. When the barrel is tilted back to its regular position, (see dotted lines in Fig. 1,) the ejector devices are caused to assume their normal set position by the ejector-head working against the face of the recoil-block.

I claim as my invention and desire to secure by Letters Patent- 1. In a breech-loading firearm in which the barrel is hinged for breakdown action, the

combination, as described, of the barrel-hinging joint-block provided with a transverse hole therethrough for the joint-pin, and .a longitudinal ejector way-bore overlying and partially intersecting with said transverse hole, a'joint-pin 'having'an upright shoulder, disposed across the 'ejector-*Way,.and'an external 'arni provided with a locking device, the ejector-bar monntedwithin the ejectorway with its end abutting on said shoulder,

said ejector-bar provided with *anunderre cess fitted with an intermediate 'oifset, the ejector-actuating spring, a retaining-catch within said recess,against which saidoffset engages subsequent to a primary movement of the ejector, and the means for retracting said catch to release'theejector foraction by said spring, substantially as set forth.

2. In a'breech-loading firearm, the'co-mbination with the stock-frame and the" barrel pivotally connected to the fore end *of said framefthe joint-screw provided with a-cran karm attached to its head end, and a swinglatchpi voted in said arm-and adaptedto close down and latch into'a'rec'essin' the'frame, and'to swing outward asa crank-handle, for

the purposes set forth.
