Emmens, of London, England. The device is thus de-scribed by the inventor : The figure represents an elevation of a torpedo-gun and abird-torpedo, partly in longitudinal section, illustrating thisinvention. The firing mechanism, which especially distinguishes thepresent weapon, comprises a wooden stock .4, fitting into andsupporting a metallic tube B, and axially perforated and slottedat its front end to accommodate within said tube a rod (,which is bent at right angles at its rear end to form a trigger D,that projects outward through a bayonet-joint slot a in the stockA and tube B. The front end of said rod C is fixed in a pistonJi, which carries a firing pin /, and between said piston and thefront end of the stock .-/ is a spiral spring .t / hence, when the. trigger D is pulled back and turned into the holding-notch ofthe bayonet-joint slot a said spring s is compressed, and whenthe trigger is released the spring urges forward the piston £,with its firing-pin Flo explode the propelling-charge P. Thisis contained within a short gun cartridge shell or powder-tubeG, which fits into the front end of said tube B and is coupledthereto by a pair of bayonet-joints i. Preferably the powder-tube, as it is hereinafter termed, is provided with a primer-recess F in its breech end and with an axial ignition-tube //,extending forward from said primerrecess to the front of thepropelling charge. The latter may be of any suitable ignition-tube is filled with gunpowder, and the recess /• isprovided with a suitable percussion primer. When the latteris exploded by the firing-pin F, a sheet of flame is producedwithin the tube //, which ignites the propelling-charge F at itsfront end, so as to insure its
