On top of and at a point between the A still further object of the invention is to two shotgun-barrels is arranged a rifle-bar provide a firing mechanism which may be in rel 5 of any desired caliber, and on said rifle stantly adjusted to operative position for the barrel are arranged sights 6, which may be firing of the ball-cartridge and as quickly ad of any ordinary construction commonly em justed to inoperative position should it be de ployed for rifles, while the barrels of the sired to use the shotgun in the ordinary shotgun are so arranged with respect to each anne. other and the sights as to permit accuracy of With these and other objects in view, as 95 45 will hereinafter more fully appear, the inven aim up to any desired distance. At the breech tion consists in the novel construction and ar end of the barrels a recess is formed for the rangement of parts hereinafter described, reception of the extractor 7, that is operated illustrated in the accompanying drawings, and in the usual manner, although the extractor 9. 772,809 instead of extending only between the two barrels of the shotgun is constructed with an the gun, the upper portion of said lug being upwardly-extending portion 8 in order to ex recessed to form a shoulder 31, which may at tract the ball-cartridge. The breech-block 9 times engage with the shoulder 21 of the bar 18. is provided with suitable guiding-openings Under normal conditions when carrying the for the passage of firing-pins 10 for the shot gun with the parts adjusted for firing both of cartridges and with an auxiliary opening for the shot-cartridges the parts will be in a po the passage of a firing-pin 11 for the ball-car sition illustrated in Fig. 5, with the bar 18 at tridge, this latter opening being arranged at its lowest position, and when in this position O an angle to the line of the barrel, so that the the bar 18 will be so depressed that when the head of the firing-pin will be adjacent to one hammer 14 is actuated its lug 30 will pass 75 or other of the hammers of the shotgun, the over the top of the shoulder 21 and to one side pin being shown in the present instance at a of the upper finger-piece 22 of said bar. The point near the firing-pin of the right-hand spring 27 will tend to hold the bar in this de barrel. pressed position, and the small compression The hammer for the left-hand barrel of the spring 19 serves to hold the rear face of said shotgun may be of the ordinary construction bar in engagement with the catch 17. and operated in the usual manner by means When the sportsman desires to fire a ball of a trigger 13; but the hammer 14 of the cartridge, a forward movement is imparted right-hand barrel is of such construction as to the trigger-like finger-piece 26 and the to operate on either the firing-pin of the shot bar 18 is raised from the lever 24 until the cartridge or the firing-pin of the ball-car shoulder 20 on said bar is caught and held by tridge.
