SPECIBLUATIO'N forming part of Letters latent No. 644,040, dated February .30, 1900.

Application filed December 21,1899- Serial No. 741,103. (No model.)

Be it known that I, llL-lRTIN BYE, a citizen of the United States, residing at \Vorcester, in the county of \Vorcester and State of Massachusetts, have invented a new and useful Improvement in Ejector Mechanism for Firenrms,of which the following, together with the econi n'inying d rnwings,is nspeciiicntion sufliciently, full, clear, and exact to enable persons skilled in the art to which this invention :ippertziins to make and use thesnme.

The object of my present invention is to provide simple, ellicient, and inexpensive authe nature oi". my invention.

tomziiic ejector for brealnlown shotguns and similar firearms; nlso,to provide menus where by the ejector mechanism is adapted as a ehecl; or stop for limiting the breakdown incveincr the barrel.

lily invention consists, first, in the peculizirlvconstrucred hitching and releasing devices, c nbined vritn the ejector-stein; second, in the peculiar construction of :1. starting device, incomhinntion withihe hitching-lever nnd ejector, and, third, in the provision of a stud in connection with the ejector latching and releasing lever, itlltl :i rctniningspnce in the barrel-hinge lug for the purpose of limiting the movement thereofnnd checking: the tiltof the barrel.

In the drawings, Figure l is a vertical section of so much of n firearm as will illustrate Fig. 2 is a similar View with the barrel tilted. Fig. 3 is 'aplan section, and Fig. i is a transverse section, :it line X X in 1; and Fig. 5 is a side view of the hinging block or lug and indicating the lever as used without the starter device.

Referring to the pin-ts as shown in the drawings, A indicates the frame, 15 the barrel, having the lug l) thereon and hinged to the fore end of the frame by the hinge-pin a, and O the ejector, consisting of a rod or stem disposed within the usual longitudinal bore 0 in the barrel-hinge lug b and having a. suitable head 0 for engaging against the rim of the cartridge shell in well known manner, a spring E within the here at the inner end of the ejector-stem serving for forcing the ejector, outward.

'lheejector-stem C is provided with a catchnotch 2 and n stop-shoulder 3 on ilslower side, and beneath the said stem I arrange a catclr lever D, disposed within a longitudinal vertical slot in the lug l), which slot coincides with and opens into the bore 0. The catchlever is pivoted near its rear end on a pin i, that passes transversely through the parts, so that said catch-lever can swing up and down Lt its fore end. its upper surface is fitted with a nose or (letent 5 for engaging the notch on the ejector-stem. A suitable spring l is combined with the catch-lever, preferably at coiled wire seated within a recess 6 above the rear end 7 of the lever, its showi'n'for normally pressing said catch-lever toward the ejector-stem.

Fixed in the lever D at a suitable distance from the fnlcrum-pivot l I arrange a horizontally-crosswise pin 1, the ends of which extend through holes J, formed in the opposite sides of thelug b and project beyond the outer surface thereof for a short distance within recesses 8, formed in the opposite in-- terior checks of the frame A. Said recesses are undercut, so as to form horizontal shoulders 10 at the upper part of the inner side surfaces, between which the lug h is embraced, and the wing-studs or ends of the pin I strike against said shoulders when the gun-barrel is tilted, as in Fig. 2. The recesses S are best formed by sinking a suitable inilliiw-tool into the top of the frame at 9 and then carrying it horizontally to cut out beneath the shoulders 10 to the required extent.'

The diametric size of the openings J is such as to arrest the wing or cross-pin at its' top and bottom, thereby confining the movement of the catchdever within the limit of the ejector-notches, or so that it will swing elf from the notch or shoulder 53 only to catch the shoulder S and vice versa. r

Forward of the catch-lever D, 1 preferably arrange a starter device K, which consists of a triangular piece of metal mounted within the slot adjacent to the end of the cutclrlever and adapt-ed to have a. swinging action on the pivot-pin 12. Its top end or point 13 is dis posed in a manner to act against the end shoulder of the ejector and. its rear or lower part provided with a too or detent 1 5, with which the. end of the (b itclrlevcr engages for tom edge of said holes,

operating the starter when said catch-lever is depressed. The hinge-pin a has a handle 16 jointed thereto, as at 17, which can be folded down into a recess in the side of the frame, as indicated in Fig. 8, or raised for unscrewing the pin. I

In operation the act of breaking down the barrel on its hinge brings the ends of the cross-pin I against the shoulders 10, causing depression of the catch-lever D and releasing its nose 5 from the notch 2. At the same time the end of the catch-lever actuates the pivoted starter K, causing it to rockl backward, swinging its top end against the the ejectorrod and forcing said ejector by a positive movement for starting the shell in the event of its sticking somewhat in the barrel-chamber. The ejector-spring then throws the ejector outward to-its full limit of action, which '20 is governed by the shoulder 3 striking the lat-c115. The cross-pin ends by being arranged through the holes J bring up against the botand thus, in.combination with the shoulders 10, serve as a check or limiting-stop for the barrels at breakdown position, Fig. 2. When the barrel is brought back to normal position, Fig. 1, the ejector is forced in in the usual manner, and the spring F causes the lever D to assume its first position in look with the ejcctonnotch'2.

In some instances, if desired, the catch-lever D may be employedwithout the starter K, the latter being omitted, as indicated in Fig. 5. Such modification, which I include as a part of my inventiomis fully operative for releasing the ejector, but does not apply a positive ejective force at the start, and I therefore preferthe construction as shown in Figs. 1 and 2, in which the starter is employed.

What I claim of my invention, and desire to secure by Letters Patent, is-

1. An ejector mechanism for firearms, comprising the ejector-rod having a notch and stop-shoulder on its underside, an ejecting v spring therefor, a horizontally-pivoted catchlever withina vertical slot in the barrel-hinging lug, said lever adapted for engaging the cjcctor'rod notch, a cross-pin fixed in said lever, its ends projecting laterally through openings at the sides of the lug, and a spring for said cateh leverg in coml ination with the barrcl-hinging lug, and the frame provided with interior shoulders or offsets against which the projecting ends of said cross-pin are brought to contact by the breakdown movement of the barrel, substantially as set forth.

2. In a breakdown firearm, the comhina tion, with the ejector-rod having a notch, a stop-shoulder and forward shoulder, and tho ejector-spring acting against the same; of the movable catch-lever pivoted within a slot in the v barrelincutof the ug and carrying a nose or detent that e-nga s the ejector-rod, and a laterallyprojecting er0ss-pin that engages ofisets in .thefrarne, a spring a pivoted starter-piece mounted within the slot, with its top end engageable with the ejector-rod, said starter operated by movecatch-lever, substantially as set forth.
