Serial No. 283,722.

To all whom it may concern:

Be it known that I, BERT W. PUNoHEs, a citizen of the United Statesof America, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Guns, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to guns and has more particular reference to constructions of relatively large caliber and the invention consists in certain novel features of con struction as hereinafter set forth.

Figure 1 is a perspective view of a portion of the gun; Fig. 2 is a side elevation of the frame, with the detachable plate thereof removed; Fig. 3 is an elevation of the detached plate, looking at its inner face; Fig. 4 is a cross section taken substantially in the plane indicated by the lines {UH-:1. and of Figs. 2 and 3; Fig. 5 is a detail view, illustrating the safety appliance for preventing accidental firing; Fig. 6 is a sectional elevation of the frame and magazine, showing the parts in a different position from Fig. 2.

Among the particular objects of the present invention are, first, the reduction of the length of frame; second, the incasing of all the mechanism in a practically-closed housing with the opening for the ejected shells at the side of the frame; third, the provision of a breech-actuating mechanism which is operable while the gun is held in firing position and one in which the breech-block, when closed, is rigidly locked to the frame; fourth, a compact arrangement of magazine within the frame and opening at the side.

To these ends the invention consists in the novel. construction, arrangement and cooperation of the parts of the mechanism as hereinafter described and particularly set forth in the claims.

By attaining these objects I am able to use a relatively longer barrel without in crease in the total length of the gun and the mechanism is protected from dust and dirt.

The frame of the gun comprises a side plate A, a top plate B preferably. integral, together with an opposite side plate C which is detachable. The top plate B is provided with a downwardly and rearwardlyeXtending shank B which is secured to the stock, while a complementary shank B is attached to the lower side of the stock and is fashioned to form a trigger guard B secured to the plate A by the upwardly-extending portion The top plate B extends the full width of the frame throughout its entire length and thus, when the barrel D is secured to this top plate and the side plate A, a strongly-braced connection is formed between the same and the stock.

E is the breech-block which is longitudinally slidable within the frame, being guided by a flange a engaging a channel I) cut in the frame plate A adjacent to the top plate and, further, by the flange 0 on the opposite side of the block engaging a longitudinal channel 61 in the detachable frame plate C. i The block is locked in closed position by a rigid shoulder F depending from the top plate B, the rear end of the block abutting against this shoulder and being engaged and disengaged therefrom by a vertical movement. This vertical movement is permitted by a lateral enlargement of the guide channel I) in the forward ortion thereof, while the channel d in the ate C terminates in an aperture 0 in the p ate C, through which the shells are ejected and which is opposite the breechblock in closed position.

As has been stated, it is one of the objects of the construction to provide an actuating mechanism for the breech-block and asso ciated parts, which is readily operable while the gun is held in firing position. I therefore replace the actuating-lever (usually employed with guns of relatively large caliber) by a sliding handle G such as frequently used on small caliber guns. It is, however, necessary in retracting the breech-block, first, to draw it downward out of engagement with the shoulder F so as to permit it to slide rearward in the guide channels I) and d and it is equally important to provide means for' positively engaging the block with said shoulder and rigidly looking it in this position when in condition for firing. These two functions are performed by a toggle lever construction comprising an arm I-I pivoted to the pin II, preferably engaging the portion B of the frame, and a toggle link I pivoted to said arm. The opposite end of the toggle link I is pivotally connected to a link I extending longitudinally of the block E and pivotally attached to the forward end thereof. A bearing 6 is also formed on the lower side of the block E, against which the end of the link I abuts when the toggle is straightened, and the proportion of the parts of the pivots in the straightened position of the toggle levers and thus it is apparent that when the handle G is drawn rearward, the first action will be to break the joint of the toggle lever and permit the downward move- 'ment of the breech-block E. A further rearward movement of the handle will, after the breech-block is disengaged from the shoulder F, draw said block rearward, the angular movement of the arm H being compensated by the downward swinging of the link I.

Before the breech-block E can be moved backward as just described, it must be disengaged from the shoulder F. For this urpose, I provide positive actuating mec anism which, asshown, consists in a vertically slidable member J preferably engaging a guide slot J in the inner face of the detachable side C of the frame. This slide or couple J is provided with a groove J 2 which, in one position of theslide, is in alinement with the channel d. The slide is further provided with a groove J below the groove J and which engages the projecting end of the pivot I connecting the links I, I. The arrangement is such that when the toggle levers are actuated by the rod G as has been described, to break the joint and draw the link I downward, this movement will communicate a downward sliding movement to the slide J through the medium of the pin I and by reason of the engagement of the flange c on the breech-block with the groove J in the slide, said breech-block will be positively drawn downward with the link.

The firing mechanism comprises a concealed hammer K which is arranged between the side plates of the frame and is preferably pivoted, as shown at K, to the detachable side plate 0.

K is a coil spring surrounding the pivot K and connected to the plate 0 and hammer K, so as to place the spring under tension when the hammer is drawn downward in cocked position, as shown in Fig. 3.

L is the trigger which directly engages with the hammer in cocked position and which also is preferably pivotally attached to the side plate C, as at L. The trigger L is shouldered at L to engage with the hammer and is yieldably pressed towards the hammer by the spring L. A trigger lock is provided which, as shown, comprises a'notched memberlNI connected to one end of a finger lever M which is pivoted to the plateC and the actuating end of which projects outward through a slot adjacent to the shank B of the frame. This notched member cooperates with a stationary pin or shoulder i 2 upon the plate C, the arrangement being such that when the finger lever M is moved in one position, the member M will be inserted between the stop M and the trigger, preventing actuation of the latter.

The hammer K is cocked during the rearward movement of the breech-block by engagement of the pin I therewith. This pin, as has been already described, projects beyond the links I, I, one end thereof engaging a segmental channel N in the plate A and the opposite end engaging a corresponding segmental channel N in the plate C. These two channels serve to guide the path of the pin and link I during the swinging of the arm H under the actuation of the rod G and the path of movement is such as to carry downward the hammer K until it engages with the shoulder L of the trigger. The reverse movement of the rod G will return the breech-block and toggle lever, as has been already described, removing the pin I from the path of the hammer and permitting the latter when disengaged from the trigger to swing upward under the actuation of the spring K striking the firing pin 0 which projects rearward beyond the breechblock.

To prevent accidental firing before the breech-block is in position, i. e. in full engagement with the shoulder F and locked by the straightening of the toggle lever, the hammer is cut away at K breech-block is turned downward out of en- Thus, when the gagement with the shoulder F, the blow of the hammer, if released, will be delivered against the rear end of the breech-block, the

projecting end of the firing pin O entering i the recess K and receiving no impact. The necessary clearance for the firing pin is further provided by cutting away a portion of the projecting end of the latter, as indicated at secured in position, preferably by a tongue and groove engagement of the upper edge thereof with the top plate B and by a securing screw which forms the pivot H. in position, the trigger and hammer will be arranged in proper operative relation'to the other parts of the mechanism, 'clearancebeing provided for the independent movement of the swinging arm H by arranging the plane '2 The side plate C of the frame is detachably d When 1 The The construction as thus far described may be employed in guns which are either with or without a magazine. I have, however, illustrated a construction of magazine which is particularly adapted for the constructions of gun above described and which is compactly arranged in relation to the other parts of the operating mechanism. As shown, this magazine is in the form of a segmental casing Q arranged beneath the breechblock in closed position and provided with a sliding cover Q. forming one side thereof.-

R is a follower for moving the cartridges upward in the magazine Q, this being formed at the end of the lever R, which is pivotally attached at R to the lower side of the barrel.

R is a spring for actuating said lever R to place an upward .tension on the follower.

S is a spring secured to the under side of the top plate B of the frame above the magazine, said spring being of the curved cross section shown adapted to receive the uppermost cartridge when the breech-blo ck is retracted and to direct the same into the barrel When the breech-block travels forward. The sliding cover Q of the magazine is preferably attached to a lever Q? which is secured to the pivot R which engages the lever R.

Vith the construction just described, the magazine may be loaded by merely drawing downward the slide Q which permits of placing a series of cartridges within the magazine. To facilitate this operation, a lug Q is arranged on the lever Q which engages with the lever R of the follower so that the operation of drawing down the slide will simultaneously retract the follower. Thus, the follower will always be arranged beneath the cartridges and, when the latter are in position, the slide may be closed, moving independently from the follower and permitting the latter to move automatically under the actuation of the spring when the breech block is retracted and the empty shell is ejected.

This construction of magazine permits of loading the gun at any time with single cartridges, holding the magazine in reserve. Thus, when the magazine is full, after the firing of the first cartridge and its ejection by partially drawing down the slide Q, another cartridge may be inserted in the magazine to take the place of the one used.

By reason of the closed top of the frame, the hammer K is concealed from view but to indicate the position of the hammer, slot T is formed in the top of the frame and the hammer is provided at its end with a projecting flange T which passes into said slot when the hammer is in upright position. Thus, when the hammer is cooked, this flange will be withdrawn and its absence will indicate to the user the condition of the hammer.
