Jan i11 drawin s means for carr in the The un is firedb tri ersSland 11 o erated I. b b b 53 DC 7 mounted on the side of the barrel 2 in approximately the same horizontal plane as that of the barrel so that the line of sight is approximately parallel to the line of the sight of the gun. A plurality of tapered tongues '15 and 16 are brazed on the side of the barrel 13, clesigned to fit in oppositely disposed tapered lugs 17 and 18 brazed on the side of the gun barrel 2 to afford a mounting of the arm on the side of the gun. A cam 19 formed on the end of an arm 21 pivoted to the side of the barrel 13 by a pin 22, is adapted to fit against the rear mount and hold the barrel securely in position.
"While the drawings show a small caliber rifle mounted on a double barrel shot gun, it is manifest that it may be attached to any other type of shot gun or that a small gauge shot gun may be substituted for the rifle for attachment on a high powered rifle.
The barrel 13 is formed with a boss 23 at the top-of the butt to which there is pivoted a breech block 24 through lips 25v and 26 by a pin 27, as shown in Figures 5 and 6. A plurality of pins 28 and 29 are set in the outer face of the lips 25 and 26 below the pin 27 adapted to fit in grooves 31 and 32 cut in ears 33 and 34 formed on an extractor 35, as shown in Figure-7.
The extractor 35 is adapted to'slide in a slot 36 cut in a mounting plate 37 formed integral with the bottom of the barrel 13. A
plate 38 is fixed on the bottom of the mounting plate under the slot 36 by screws 39, and formed with a groove 41 upon which the extractor 35 is adapted to slide. When the breech block 24 is rotated around the pin 25, the pins 28 and 29 operate in the grooves 31 and 32, and force the extractor back in the slot 36 011 the mounting plate in the groove 41. Arecess 42, concentric with the face of the barrel is cut inthe breech to receive the rim of a cartridge and the bottom cut away to seat on extractor claw 43 formed integral with the extracting mechanism 35. 'A lip 44 is formed on the extractor claw adapted to fit against the bottom of'the breech block 24, and retain position when the breech is locked.
A firing pin 45 is mounted in an aperture 46 bored in the front .of the breech block 24. A groove 47 is cutin the bottom of the firing pin 45 adapted to cooperate with a pin 48 fixed transversely across the aperture 46 and hold the firing pin in position.
A rod 49 threaded at both ends is mounted in the rear end of the breech block, adapted to engage a striker 51 and a cocking piece 52. A coil spring 53 is mounted between the striker pin 51 and the rear of the breech block 24, so that when the rod 49 is drawn out and released, the striker 51 will contact with the firing pin 47 under the force exerted by the spring 53.
The cooking piece 52 is formed with a shank 54 terminating in an integral tapered locking plate 55. T he shank 54 is adapted to pass through a slot- 56 cut inthe mounting plate the breech block by a pin 59, having a toe 60 adapted to engage ahalfzcock notch 61 and a full cock notch 62 formed on'the sear. One end of a leaf spring 63 is mounted on the bottom of the sear by a screw 64, and the other end held by a pin 65 embedded in the side of the mountingplate 37. V A boss 66 is formed on the side of the trigger mechanism to which is hinged a trigger 67 by'a pin 68" so that it may be raised to an upright position when not in use as shown in Figure 8.
A slot 69 is cut through the mounting block adjacent the slot 56 toreceive the locking plate 55 together with an adjo iningslot 71 to receive the shank 54. VWhen the cooking tion of half cook the locking plate may be raised through the slot 69 and the breech block rotated forward so that the extractor is forced back and a cartridge started from .95 .piece 52 is drawn back slightly past the posi- 1 c the chamber, where it may be withdrawn and v another inserted. I
.The bevel surface on the locking plate 55 permits the breech block to be snapped shut and the gun carried at half cock without the possibility of the action swinging open at half Q cock; When the toe 60 of the sear registers in the full cock notch 62, the lever 67 is adapted to be pressed by the thumb, which may rest across the small of the stock 6 on the piston grip 5. I
The rifle is attached to a side of the shot 1 Eli gun of either a single or double barrel type I through the tapered tongues and grooves 15 and'17 and 16 and 18 and locked by the cam 19 where it may be readily removed by disengaging the cam. A rear sight 69 havinga slot 71 is screwed onthe top'of the breech block by a screw 72 and a frontsight 73 hav--; ing a head 74 is mounted on the muzzle of the barrel. If so desired a peep'sight may be conveniently mounted on the breechblock or on the end'of the mounting plate 37 lhe toe 60 is ordinarily allowed to rest in half cock position and when it is desired to cock the rifle the cooking piece is pulled back until the toe engages thefullcock notch on the sear. The tapered plate 55 is disengaged from the mounting block through the slot 69, so that the breech block may be rotated for- Ward and the barrel l l hen the fire the weapon it is pulled back by the COCliing piece, as previously tated, until the too regist the full c ex the sear where it may be fired by pressing the trigger G7.
There is accomplished by this invention an auxiliary rifle or o n for large bore guns or h caliber rifles mat may be easily and fixedly mounted on a firearm and accurately aimed without interfering With the sight of the weapon. to which attached and readily detached and conveniently carried apart from the Weapon.
