FIREARM.

Specification of Letters Patent.

Patented Oct. 13, 1914.

Application filed January 2, 1914. Serial No. 809,913.

To all whom it may concern:

Be it known that I, ALVAH E. GmMEs, a citizen of the United States, residing at Nor wich, in the county of New London and State of Connecticut, have invented a certain new and useful Improvement in F irearms, of which the following is a specification.

My invention relates to tire arms and more particularly to single shot rifles of relatively small bore, my object being to provide an extremely simple, cheap and effective form of ejector which will act, automatically, to throw out an empty cartridge shell, or will act forcibly, to start, and extract from the barrel, a stuck shell.

The invention is clearly illustrated in the accompanying drawings, in which Figures 1 and 2 are side elevations, partly in section, of the frame and a portion of the attached barrel, of an arm embodying my said invention; Fig. 1 illustrating the lock mechanism with the hammer down as if the arm had just been discharged, and Fig. 2 illustrating the same parts as they appear just at the instant when a spent cartridge shell is being ejected from the barrel. Fig. 3 is a detached perspective View of the breech-block of the arm, and in Fig. 4: I have shown side and edge views of the ejector proper.

Referring to the annexed drawings, the numeral'lO indicates the breech-frame of an arm and 11 denotes the barrel secured to the frame, as here shown, by screw-threads.

12 is the hammer, 13 the trigger, 14 the trigger spring, operating as a yielding spreader between the said trigger and the upper tang-portion of the frame, and 15 is a so-called kick main-spring abutting the notched front side of the hammer and secured, at its front end, to the under side of the barrel, by a post 16.

The breech, or recoil block 17 is pivoted in frame 10 at 17 in such manner that said block may have a downward drop when the hammer is cocked, or half-cocked as the case may be (see Fig. 2), and said block is milled or otherwise, cut away, as at 17, to provide a recess in which is located an ejector arm 18 which is pivoted in frame 10 at 18 and is formed with a rearwardly extending angle-arm 18 whose end lies in the path of the breech-block 17, when the latter drops to its lowermost position (see Fig. 2),

and so that the impact of the breech-block with said angle-arm will operate to rock the free (upper) end of the ejector arm 18 rearward to throw the cartridge shell out of the barrel; the said free end of the ejector arm being suitably shaped, as at 18, to engage the head of the shell. The end portion of block 17 which is pivoted at 17 is formed with a downwardly extending, angular, portion 17 which is engaged by the free end of a stiff spring 19 whose front end is secured to the barrel 11 by the post 16 already mentioned. When the breech-block 17 is in its closed position, as in Fig. 1 of the drawings, the spring 19 operates to hold the said block closed. l/Vhen, however, the block is dropped slightly and the angular arm 17 passes away from the vertical dot-and-dash line so (Figs. 1 and 2) the 5 ring 19 then operates to throw the bloc: 17 downward quickly and forcibly, thus causing said block to engage the ejector angle-arm 18 with a hammer-like blow sufficiently strong to rock the ejector arm 18 rearward and thus eject the empty shell from the barrel with a quick movement. In the event that a shell should stick in the barrel, the peculiar arrangement of the cooperating breech-block and ejector arm is such that the downward movement of the said block, manually, will furnish sufficient leverage and power to start the stuck shell from the barrel. It will thus be seen that the described mechanism may act as an automatic ejector, to throw the shell out of the barrel with a rapid move ment or it may operate as an extractor to start a stuck shell and withdraw with a relatively slow movement.

In order to start the breechblock on its downward movement when it is desired to eject a shell, or for the purpose of loading the arm, I have provided, as here illustrated, a thumb-piece 20 which projects laterally from one side of the said block, near the top portion of the latter.

My described improvement is of extremely simple, and inexpensive, construction yet it operates positively and is particularly convenient for use with rifles of small bore.

Having thus described my invention, I claim as new and wish to secure by Letters Patent In a fire arm, the combination with a barrel and a breech frame, of a breech block pivoted in said frame and provided with a recess, an ejector arm pivoted in the frame and located in said recess, a spring having one end secured to the barrel, the breech block having a depending angular arm directly engageable with the free end of said Witnesses: spring, and the ejector arm provided with a FRANK H. ALLE rearwardly extended angle arm engageable ELSIE P. GRUNERT.

directly by the said recoil block as the latter drops.
