Abstract

720,157. Parachutes. GREGORY, J. June 30, 1953, [July 1, 1952], No. 16520/52. Class 4. A parachute pack consists of a container made principally of flexible material, but preformed to the shape of a substantially rectangular box or satchel, having its outer surface or wall provided with closure flaps and with stiffening means for resisting the pull of the flaps when closed so as to restrain the outward bulging of said flaps, and also having its opposite surface or wall restrained from bulging outwards when the parachute is stowed in the pack, so as to maintain a shallow box-like shape of the container. The pack is made of canvas or other flexible material closed on one wall by four flaps, three 19, 21 and 22, being shown in Fig. 4, secured by locking cones 23. This wall is stiffened, and the pull of the flaps is resisted, by a wire frame 16, and the opposite wall 35 of the pack is provided internally with a stiffening member comprising a central member 36 and two transversely arched members 37 of strip steel or other metal so shaped that they press evenly against the wearer's body and prevent the wall of the pack from bulging outwardly. A partition flap 32 separates the member 36, 37 from the main canopy 25, and a pilot parachute 26 is located between the flaps 19 and 21, 22 within the area of overlap, and is separated from the main canopy by an ejection board 27. Specifications 531,882 and 531,884 are referred to in the Provisional Specification.
