IMPROVEMENT IN BREECH-LOADING FIRE-ARMS.

Specification forming part of Letters Patent No. 190,820, dated May 15, 1877; application filed October 11, 1876.

To all whom it mag concern.-

Be it known that I, HERBERT W. CHAP- MAN, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Fire-Arms, of which the following is a specification, reference being had to the accompanying drawings.

The invention has relation to an improveing the breech, a breech-frame, triggerguard,

hand-guard, and other parts of the stock in a single piece, and arranging them in the manner hereinafter fully described.

In the accompanying drawing, A denotes the breech of the piece; B, the breech-frame; O, the trigger-guard; D, thehand-guard E, the gripe F, a loop, to which the cord to fasten the piece so as to prevent its loss when in use is attached; and I], the stock proper, the whole cast or formed of a single piece of 7 metal.

The breech A is preferably relatively rectangular, its interior and rear parts being suitably formed and arranged toaccommodate the breech-block, hammer, firing-pin, and

other similar parts. Immediately below it is the breech-frame B, in which a mainspring is properly secured to operate the hammer, and in rear of the breech-frame B are the triggerguard O, hand-guard D, and loop F, all arranged as appears with suificient clearness by the drawing.

By so disposing and arranging the different parts I efiectively insure great strength without sacrificing other important considerations. The breech-frame B, while enabling me to use a powerful mainspring without interfering with the convenient operation of the mechanisms at and near the breech, materially strengthens the guards and contiguous parts, and the guards likewise strengthen each other, besides enabling me to construct the gripe E of such size that it can be readily grasped, and still be of sufficient strength.

By preference I construct the stock without a cheek-piece, in the form of a frame, as shown in the drawing, to avoid the possibility of too great weight; and I exercise due care in so adapting the size and weight of all the parts as to insure a desirable balance for the gun when in use. The loop F may be omitted or supplied at will. I do not regardit-as an element of the invention. Neither do I limit my claim to the exact forms of the different parts described, as they may be varied, in whole or in part, without evading the scope of the invention; but

What I claim as new and useful, and desire to secure by Letters Patent, is

1. The construction of the breech-frame B, guards (J and D, gripe E, and stock H, cast in one piece, substantially as specified.

2. In a fire-arm, the breech-frame, stock, and guards, formed in a single piece, substantially as set forth.

In testimony that I claim the foregoing improvement in firearms, as above described, I have hereunto set my hand this 28th day of September, 1876.
