of the United States Arm. retired', a. citizen of the United States, resi ing aty New York,

in the county of NewYork and State oflN ew l York, have invented certain new and useful lImprovements in T-o edo-Guns, of which I the following is a s peci cation.

' This invention relates to guns fo'1.propelling torpedoes.

1 The 'object of the invention is to produce a gu'n from which torpedoes or similarl projectiles for submarine action maybe thrownwith different' velocities, obtaining dierent ranges the combustion 'of similar powder vcharges without-changing the elevationof the gun. 1 f To this end the invention 'consists in a' gunv having a large combustion-chamberV and I neans; to regulatethe amount of 'ourdeligas,v which'may pass from this chan1 e rto the barrel in wlnch vthe projectile is seated, .thus acting thereon'an'd at the same. time permit. theescape of surplus gases.

In Fig. 4 the numeral 21 denotes the gunbarrel proper, which-barrel is closed behind a projectile by the slidingtrap 22, which has a i passage 23 'large enough for the projectile to enter. Chamber 24 in rear of the barrel proper is closed by any. suitable fermature,
