drawings, and to the letters of reference marked thereon, which form a part of this specification.

The object of this invention is to provide a gun with side locks which may be removed by hand without the use of a tool and without the necessity of removing the usual screw or screws which hold the locks in place in the frame and also to so attach and construct the lock-plates, the trigger plate and trigger guard that no screws or pin heads will be visible on the outer face of the parts to mar the appearance and finish of the arm.

As shown in the accompanying drawings:Figure 1 is a side elevation of the parts at the junction of the barrel and stock of a double-barrel single trigger shot gun, showing means for holding the lock-plate from being forced or jarred rearwardly from the action of the recoil or hammer. Fig. 2 is a plan view showing the lock-plates and means for connecting the same, together with the parts of the breech-frame and stock immediately adjacent to the said lock-plate.

Fig. 3 is a view of the rear ends of the lock-plates and the connecting lugs, showing the latter separated from each other Fig. 4 is a sectional view of the same parts shown in Fig. 2. Fig. 4 is a sectional view showing a modified form of spring for actuating the bolt or latch of the lock-plate connecting devices. Fig. 5 is a detail section taken on line 5-5 of Fig. 2, showing in section the interlocking parts by which the lockplates are connected with each other, together with the means for disconnecting the same in removing the lock-plates. Fig. 6 is an enlarged detail section, taken on line 66 of Fig. 3. Fig. 7 is an enlarged detail section showing the spring for lifting the vertically movable pin forming part of the disconnecting device shown in Fig. 5. Fig. 8 is a side view of the'trigger plate, the trigger guard and rear end of the tang, showing the connection of'the trigger-guard with the tang, and also the connection of the forward end of the trigger plate with the breech frame.

Fig. 9 is a detail face view of the end of the trigger plate which engages the breech frame. Fig. 10 is a view in side elevation like Fig. 1,- showing a modified construction in the means for holding the lock-plate from rear ward movement. Fig. 11 is a view like Fig. 10 showing still another means for holding the lock-plate from rearward movement. Fig. 12 is a plan view of the lock-plate shown in Fig. 11, with adjacent parts of the breech frame and stock in section. Fig. 13is a detail section through the rear parts of the trigger plate and trigger guard, showing a modified construction in means for attaching the trigger guard.

As shown in the said drawings, A indicates the breech frame, B the stock, and C C the lock-plates. The looks or hammer actuating devices, not shown in the drawings, are mounted on the inner faces of said lockplates in the usual manner.

In carrying out my invention the several screws and studs or pins on which the parts of said locks are mounted, extend only partially through the thickness of said lock-' plates, so that the outer surfaces of the latter will be perfectly smooth and will be unmarred by the ends of said screws, studs or pins.

When the hammer falls in firing the gun, the tendency is to force the lock-plate backwardly from the breech-frame. To overcome this tendency I provide on the lockplate an enlarged end D preferably of circuar form, as shown in Figs. 1 and 2, which fits within a corresponding recess formed in the side of the breech frame; the outer face of the lock-plate being made flush with the side ofthe frame, in theusual manner. The forward end of the lock-plate is prevented from coming out of its recess in the frame by having a portion of its forward end extended to form a lip d which fits beneath an overhanging ledge a on the frame, as clearly seen in Fig. 2.

The rear ends of the lock-plates are held in position by means of two lugs E E which eX- tend inwardly from the rear ends of said plates and are adapted to meet each other at a point between the plates and are there provided with interlocking devices by which they are interlocked or held together. Said interlocking devices are so constructed that when the forward ends of the lock-plates are engaged with the breech frame and the rear place by aset-screw f, Fig. 6, which is inends thereof are then inserted and pressed in place by the hand, said lugs will become in terloclred with each other, as shown in Fig. 2. The devices illustrated for connecting the lugs are made as follows: One of the lugs E in the drawings is provided with a spring latch or bolt F, as seen in Figs. 3, 4, 5 and 6, and the lug E of the opposite lock-plate is provided with. a part or projection c which overlaps the end of the lug and is provided with an aperture 6 to receive the latch. The bolt F may be thrown or forced outwardly by a coiled springf placed. between the inner end of the bolt and bottom of the guide recess in the lug E, in which it slides, as shown in Fig. 4, or by a flat spring f attached. to the said lug E and pressing 011 the end of the bolt which extends through said lug, as shown in Fig. 4 The belt is held in its sorted through the lug and the inner end of which enters a groove in the bolt. The outer or end face of the bolt F is inclined or beveled so that said bolt will be pushed inwardly against its actuating spring by the pressure of the part 0 when the two lugs are brought together.

Means for unlatching the lugs is shown in Figs. 5 and 7. The devices for this purpose illustrated consist of a rod H passing through the tang and located at its inner end in position for contact with the outer end of the latch or bolt F, which outer end of the bolt is directed upwardly or towards the tang. Said rod His lifted or thrown outwardly by a spiral spring h, which is seated. in a recess in the tang beneath a head hi on the rod. The upward movement of the rod may be limited by a stop pin 7L2 inserted through the rod, (or any other suitable stOP,) as shown in Fig. 7. The upper end of the rod is preferably located directly under the end of the top lever I of the arm, said top lever being recessed on its under surface to receive the head 7L as shown in Fig. 5. The aperture 0 of the lug E is provided with a gate or opening 6 located in line with the rod H, so that the rod will not interfere with the movement of the lug E in the latching and unlatching operation. When it is desired to remove the lock-plates, the top lever is pushed to the right in the usual manner and the rod H is then pressed down. This forces downwardly the bolt F until the same is free from the aperture 6 and thus unlatches or uncouples the lugs and releases the locleplates. Each lock-plate may then be permitted to drop out of its seat, when the gun is turned in position to bring it face downward. Manifestly the disconnecting or releasing rod H must be held down while the first lock-plate is being removed; it being readily understood that when the lock-plate having the lug E is taken out, the releasing rod H will pass through the gate 6 and will in no we y interfere with the 1 lock-plates are then pressed together until the meeting ends of the lugs thereon are latched or interlocked.

Instead of employing the enlarged circular head I) to hold the lock-plate from. back ward movement, I may employ a rearwardly facing step or shoulder D such as is shown in Fig. 10. Such shoulder on the lock-plate is adapted to engage a corresponding, forwardly facing locking shoulder on the upper part of the breech frame. Said shoulder D is shown in Fig. 10 as used in connection with the enlarged head D but it may be used separately therefrom, if desired. I11 Figs. 1.1 and 12 I have shown still another means for interlocking the lockplate with the breech frame, the same consisting of an inwardly projecting stud J which projects in wardly from the plate and fits within a re cess in the breech frame; said stud being used in connection with a lip or projection (Z which enters beneath a ledge a on the plate, as clearly shown in Fig. 12.

To avoid the presence of visible screw heads in attaching the trigger plate to the frame, I provide said trigger plate with an enlarged head K which fits within a correspondingly shaped recess in the bottom of the breech-frame and has a lip 7c which fits beneath an overhanging ledge (L2 on the frame, as clearly seen in Figs. 8 and. 9. As an improved means for holding the trigger guard Lin place without the use of any visible screw-heads, I screw the forward end of said trigger guard to the trigger plate in the usual manner and, on the rear end of said guard, I provide a solid lug Z, which lug preferably passes through an opening in the trigger plate, as shown in Fig. 8, and is engaged by the lower end of the screw M which passes from above through the tang and, by screwthreaded engagement of its lower end with the lug, acts as a bolt to connect the rear end of the trigger guard. with said tang and thereby hold said trigger plate, guard and tang firmly together. The head of the screw M will be countersunk in the rear end of the tang and located in such position that it will be covered and concealed by the usual safety slide N, which is located on the rear end of the tang.

It is not, however, necessary that the lug Z should pass through an opening in the trigger plate, as shown. in Fig. 8, as it may enter a recess formed in the lower face of said plate. I have shown in Fig. 13 a construction of this kind, in which the said lug Z is made oval or rounding'and the trigger plate is formed or recessed. to receive said lug.
