BREECH-LOADING GUN.

SPECIFICATION forming part of Letters Patent No. 781,179, dated January 31, 1905.

To whom it y COW/067"! varying, as they do, in details of construc- Be it known that I, THOMAS Gr. BENNETT, a tion; It seems to me, however, suificient for citizen of the United States, residing at New the illustration of my invention to show it as Haven, in the county of New Haven and State embodied in two finger-lever guns.

out in the claims. In Figs. 6 to 9, inclusive, of the drawings I My invention, as I may here state, is aphave shown my improvement as embodied in plicable to the construction of substantially a breech-loading finger-lever gun of the class all locking-blocks for breech-loading guns, in which the locking-block engages with the breech-bolt at a point forward of the rear end thereof. In this construction the locking block consists of two corresponding members 18, having their lower ends united by a screw 19, passing through a sleeve 20, interposed between them, the block being connected by the said screw 19 and sleeve 20 with the fingerlever 21, which is formed for the purpose with an inclined slot 22, through which the sleeve and screw pass. The forward and rear edges of the two members 18 of the block are formed with locking-ribs 23 23 and 24 and 2%, the ribs 23 and 23* taking into grooves 25 and 25 formed in the adjacent side walls of the gunframe 27, and the ribs 24 and 24 taking into grooves 28, formed in the adjacent side faces of the breech-bolt 29. Under this construc tion the locking-block couples the side walls of the gun-frame to. the breech-bolt, which then virtually forms a part of the lockingblock for tying the two sides of the gun-frame together.

Breech-loading guns like that shown in Figs. 6 to 9 are too common to need detailed description; but it may be said that after the breech-bolt 29 has reached its fully-closed position it is breeched up and held in that position by the lifting of the locking-block, which is depressed preparatory to the opening of the gun. I

In the modified construction shown by Fig. 10 of the drawings the members 30 80 of the block are provided only on their forward edges with locking-ribs 31.

In the modified construction shown by Fig. 11 the two members 32 32 of the block are formed with dovetails 33 33, while in the construction shown by Fig. 12 the two members 3 3 1 have their forward outer edges formed with locking-ribs 35, which take into the side walls of the receiver, and their inner rear edges formed with locking-ribs 36, which take into the side walls of the bolt.

It is apparent, in view of the foregoing, that locking-blocks constructed in accordance with my invention may be applied to a great variety of breech-loading guns and may assume a great variety of forms. I would therefore have it understood that I do not limit myself to the constructions shown and described, but hold myself at liberty to make such departures therefrom as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a breech-loading gun, the combination with the gun-frame thereof, of alocking-block constructed to be interlocked with the opposite side walls of the said gun-frame for tying the same together against spreading under pressures developed by the explosion of acartridge in the gun.

2. In a breech-loading gun, the combination with the gun-frame and breech-bolt thereof, of a two-part locking-block constructed to be interlocked with the opposite side walls of the said gun-frame and bolt for tying the said side walls of the frame together against spreading under pressure developed by theexplosion of the cartridge in the gun.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
