TORPEDO PROPELLING AND STEERING MEANS Filed April 15, 1942 Patented Oct. 5, 1943 "Application" My invention relates to improvementsin tor pedo propelling and steering means. f One of the objects of my invention is metropsion of novel means by "whicha self propelled torpedo of usual type can be propelled and torpedo has been released, and "which autoniatically releases when the torpedo proceeds. under itsownpower. d Still another object of my invention'gis theproj-Q vision of novel propelling and steering "means of i the kind described, whichis simple, strong,j cli1 r able, not likely to get out of order, which is easily operated to propel and'steer' theftorpedo,"jand" whichisefficientinits operation; 7 The novel features of my invention are here after fully described and claimed. j I 'In the accompanying, drawing, which illu trates a preferred embodiment of 'myinvention; Fig. 1 is a side elevation; partly. broken away, showing the "torpedo operatively lockeditoithe; propelling boat. 3 i I y Fig.2 is a top view of thetorpedo and beg t operatively connected. p f

With my invention, a small submarine, operated by one person can propel and steer a torpedo, unobserved, to close striking distance from an objective, as a battle ship or other vessel, then release the torpedo to have it continue its course to the objective, and then, due to its small size, turn away, submerged if in daylight, or on ,thefisurface, if a'tlnight and proceed from anyidang'erous location near the objective, if

, such be awarship.
