BREECH-LOADING FIREARM.

SPECIFICATION forming part of Letters Patent No. 592,196, dated October 19, 1897.

Application filed June 28, 1897.

, To all whom it may concern.-

Be it known that I, ALBERT A. CLIVE, a citizen of the United States, residing at Ilion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Breech-Loading Firearms, of which the following is a specification.

My present invention pertains to improvements in breech-loading firearms, the construction and advantages of which will be hereinafter set forth, reference being had to the accompanying drawings, wherein Figure l is a perspective view of the breechblock, hammer, and attendant parts; Fig. a similar view, partly in section, of so much of the gun-stock as is neeessary to illustrate my invention; Fig. 3, a like view of the breechblook viewed from the under side; Fig. 4, a perspective view of the trigger, and Figs. 5, (i, and 7 sectional views illustrating the parts in their different operative positions.

The object of my invention is to produce a simple and compact gun, one which does away with any intricate lock mechanism and at the same time is eflicient when in use.

In the drawings, A designates the stock of the gun, and B the barrel, secured thereto in a manner which will prevent it from moving thereon. In the'upper face of the stock there is formed a recess or chamber 0, open at its rear end, and in the bottom of which is secured a plate D, provided with an oblong slot or recess E. Mounted within the recess or chamber O is the combined breech mechanism, hammer, and trigger.

F denotes the breech-block as a whole, consisting of the side bars a a, connected at their forward end by a cross-bar b and at their rear end by the upwardly projecting breechblock 0.

G indicates the hammer, pivoted between the rear ends of the side bars a, its strikingpoint, when the hammer is down, occupying the position indicated in Figs. 1, 3, and 7. The hammer is of the form shown in Figs. 5, 6, and 7, provided with a nose d and a scarshoulder e, the former acting in conjunction with spring H and the latter with a projection f, formed upon the trigger-plate I.

The trigger-plate (shown in detail in Fig. 4) comprises a block g, a plate h, and the trig- Serial No. 642,682. (No model.)

ger or thumb-piece i, all formed integral, as shown.

Block g is provided with a cross-slot in which is mounted the spring H, said spring extending rearwardly and bearing upon the nose of the hammer, its normal position being indicated in Fig. 7. It will be noted that the rear end of the spring is inclined slightly in an upward direction, and, when the gun is cooked, bears against the rim of the cartridge, as in Fig. 5. Inasmuch as the breech-block cannot bewithdrawn unless the gun be cocked, as will presently appear, the spring acts as an extractor and forces the shell out of the barrel as the breech-block is drawn back. Upon reference to Figs. 5, 6, and 7 it will be noticed that the barrel is cut away at its rear end, forming a recess j to permit the spring to enter in front of the rim of the shell, as just stated.

The trigger-plate, which is pivoted between the bars a, as shown, is provided upon its under face with two lugs or projections J and K, the lug J being longer than the other and designed at all times to project into the slot E, its function being to limit the movement of the breech mechanism toward and from the rear end of the barrel, the extreme positions being indicated in Figs. 5, 7, and 6, resp'ectively. The relation of the lug K to the slot E is such that said lug cannot enter the slot unless the breech-block is up against the rear of the barrel, in which position said lug comes into proper position to engage the rear wall of the slot, as shown in Figs. 5 and 7. When the parts are assembled, the breech mechanism is placed in the recess in the stock,

the lug J entering the slot in the plate D. The barrel is then put in place, its under face bearing upon the cross-bar b, and a screw passed up through the stock into a lug formed on the barrel, as shown.

When it is desired to load the gun, the hammer is cooked, and by its movement the spring is elevated by the nose d, and the notch cengages the projection f, the trigger-plate at the same time being drawn up slightly, by reason of the elevation of the end of the spring by the nose d, into the position denoted in Fig. 1, in which position the lug K is withdrawn from the slot, permitting the breech mechanism to be drawn out into the position indicated in vFig. 6. So soon as there is the slightest rearward movement of the breech mechanism, the lug K bears upon the face of plate D, and consequently the trigger cannot be depressed to release'the hammer, preventing the gun from being accidentally discharged. The act of withdrawing the breechblock withdraws the exploded cartridge from the barrel. A new shell is then inserted and the breech mechanism shoved forward to its closed position. It will be noted that it Will be impossible to prematurely explode the shell, or until the breech-block is directly against the shell, for until the parts are in such-position the lug K bears upon the plate D and the trigger cannot be depressed. When said lug comes over the end of the slot E, the trigger may be depressed, and when this takes place the lug K enters the slot, releasing the hammer and exploding the cartridge. Of course as the lug K enters the slot it engages the rear edge thereof, thus securely preventing the breech mechanism from being blown back by the explosion of the cartridge.

I claim- 1. In a gun, the combination of a'stock; a recess formed therein opening toward the rear of the stock; breech mechanism mounted in and movable in and out of said recess; a hammer and a trigger carried by said breechblock; and a barrel secured to the stock eX- tending back over the recess, holding the parts in place.

2. In a gun, the combination of a stock a recess formed therein opening toward its rear; breech mechanism mounted in and movable back and forth in said recess; a hammer, and a trigger carried by said breech mechanism; means for limiting the movement of the breech mechanism; and a barrel secured to the stock extending back over the recess, holding the parts in place.

3. In a gun the combination of a stock a recess formed therein opening toward its rear; breech mechanism mounted in and movable back and forth in said recess; a trigger and hammer carried thereby; means for limiting the movement of the breech mechanism; means for preventing the hammer from descending until the breech is closed; and a barrel secured tothe stock extending back. over the recess, holding the parts in place.

4. In a gun, the combination of a stock; a breech mechanism mounted and movable back and forth thereon; a hammer; and a trigger and a spring for the hammer designed also to act as an extractor; the parts being carried by the breech mechanism.

5. In a gun, the combination of a stock; a recess formed therein; a slotted plate I) secured to the bottom of the recess; and a breech mechanism mounted within said recess and provided with two depending lugs,

one of said lugs remaining at all times within the slot and serving to limit the backward movement of the breech mechanism, and the second acting as a safety device to prevent discharge of the gun until the breech is closed.

6. In a gun, the combination of a stock; a recess formed therein; a slotted plate D secured to the bottom of the recess, a breechblock mounted in said recess; atrigger-plate pivoted in said block; and a lug depending from the trigger-plate and entering the slot in the plate.
