DEFINITION

Classification: 124/67

(under subclass 66) Apparatus wherein the piston reciprocates inside of a first tube and the missile is impelled from a second tube, and wherein the inside diametral dimension of said first tube is greater than the inside diametral dimension of said second tube, and wherein the tubes are connected for passage of fluid, whereby pressure generated in said first tube is used to impel the missile from said second tube.

(1) Note. The first tube is the auxiliary cylinder referred to in (1) Note of subclass 65.
