My impro-ved gun is ofthe typev comprising an outer or false barrel within the forward portion of which are arranged the shooting barrel and shot magazine. 'I'hese features are not, however, a part of the present invention and, therefore, will not be described in detail.

A and A are the false barrels of the double barrel gun having arranged intermediate the same the rib B. The latter is preferably formed of a single blank having a. flat top rportion B .andoppositely turned segmental side'portions the anges C by spot-welding at distributed points. It also has a portion D extending rearward beyond the rear ends of the barrels for pivotal attachment to the stock. This stock is formed of the wood portion E and the metallic portion F secured thereto, this being a member of inverted U-section which embraces the portion D of the frame and is also fashioned to close the rear end of both barrels. The pivotal connection between the stock and the member D' is preferably formed by aligned annular 20 flanges F' projecting inward from the opposite sides of the member F and engaging corresponding apertures in the member D. A clamping screw G extends through these flanges and across the members D and F, serving to holdthese` parts together Ibut the pivot bearingis formed on the anges. The stock is normally locked in alignment with the barrels by a U-shaped member H rockable on a pivot pin H extending acrossl the member F, and having at its lower ends latch hooks H2 forI engaging inturned ears D2 on the portion D. A-flat spring H3 attached to the member H and bearing against the top of the member F serves to yieldably press the latch hooks H2 into engagement with the ears D3, thereby elfecting the locking. The releasing of the lock is accomplished by a lever I pivotally attached to the upper portion oi the member F and having `extending inside the latter the crank arms I adjacent to the top portion of the. member H which is above the pivot H2.` Thus, when the lever I is moved from its central position to one side in either direction, the crank arms I will rock the member H suiiiciently against the tension of the spring H3 disengaging the latch 45 hooks I-I2 from the ears D2.

Within each of the barrels A and A is secured an abutment J for limiting the forward move- Ament of the piston J which compresses the air for firing the projectile. This piston together '5g with its tubular forward extension J2 passing through the abutment J and entering the firing barrel, is similar to constructions heretofore used and need not Ibe further described. In rear of the piston is a tubular shank J3 having a bi- 55 furcated portion J4 terminating in enlarged ends J5. Between these end portions are members J6 which are secured theretol by outwardly projecting lugs J7 passing through apertures in the portions J 5 and riveted at their outer ends. The members J 6 have downward extensions J2 which form the hooks for engagement with the sear as hereinafter described. A spring K surrounds the shank J3., its forward end abutting against the piston J and its rear end against a stop or abutment K. he latter is formed with a tubular portion K2 which fits Within the barrel and downwardly extending ears K3 notched at K4 te engage a cross pin K5 secured in the forward end portion of the frame D. Thus the thrust of the spring will be taken by the tubular 4portion K2 and transmitted through the ears K3 to the pin K5 and finally to the frame.

The springs for the plungers in both barrels are simultaneously compressed by the breaking down of the gun through the following mechanism. L is a link pivotally attached at its rear end to a cross kpin L' in the member F and having at its forward end a T-shaped head L2, which simultaneously engages the depending members J8 of the .plungers for both barrels. Thus, whenever the gun is broken down, this link will draw the plungers rearward to compress the springs K. Beneath the link L there are arranged in the frame D adjacent to each other a pair `of sear members M, each of which is of an inverted U cross section and which pivotally engages a cross pin M. The rear ends of these Sear members are notched to form the locking shoulders M2 for engaging with the depending portions J8 of the corresponding plungers. A tortion spring M3 mounted upon the pivot pin M serves to yieldably move the members M upward so as to force the same into locking engagement with the members J2, as soon as the latter have passed the shoulder M2. Each sear is released by a trigger N, both triggers being p-ivoted upon a cross pin N' and having forwardly extending bell crank arms N2 for engaging the sears M to depress` the same. Accidental operation of the triggers is prevented by a safety member O which is slidably mounted on a guide member P. This member P forms a partition extending longitudinally and centrally of the frame D between the sear members M and triggers N, being welded or otherwise attached to the bottom of the frame. The member O has a rear portion slidable on the top ofthe member P and a bifurcated forward extension, the furcations O of which are on opposite sides of the member P and the triggers N adjacent thereto. Between the furcations O" ist a downturned portion O2 slotted to embrace theguide P. 'I'here is also a transversely arranged return-bent portion O3 which engages a slot P inthe member P and holds the member O against upward movement. A downwardly extending portion O4 on one of the furcations O' passes through a slot in the bottom of the frame and forms an operating member. There is also a downturned portion O5 which is adjacent to the rear edge of the member H. The construction is such that when the member O is in its rear position the portions O2 on the opposite sides of the member P will extend into the path of a rearwardly and upwardly extending portion N3 of each trigger, so as to form a stop for preventing trigger movement. On the other hand, when the member O is moved forward by means of the operating member O4, the portions O2 will be out of; registration with the portions N3 permitting free actuation of the trigger. A latch spring O5 secured to the member O and engageable with notches P2 and P3 in the upper edge of the member P serve to yieldably hold the member O in each positon of adjustment. It is, however, desirable to automatically control this safety device so that whenever the lever I is operated to release the lock of the breakdown mechanism, this will adjust the member O into safety positon. Such operation is accomplished by the rocking of the member H against the portion O5 whenever the lever I is operated to disengage the hook H2 from the ear D2. Such rocking will move the member O rearward into safety position where it will be retained by the latch spring O6 until manually released by movement of the operating member O4.

It is usual to provide guns with a hand` hold upon the barrel which I have formed of a wooden member Q fitting beneath the barrels A and A in advance of the frame D. The rear end of this member has a tongue portion Q which is inserted within the forward end of the frame D, and the forward end portion is fashioned to fit around between the barrels. For securing it in position a bridge strip Q2 is welded or otherwise secured to the two barrels and has a threaded aperture therein for engaging a screw Q3 -passing through the member Q. Thus, when the screw is fastened the handle will be rigidly held in position.

A gun constructed asabove described, can be manufactured at low cost; is easily operated, and is automatically placed in safety when in loaded position.
