Abstract

117,092. Calthrop, E. R. March 21, 1917. Parachutes.-In parachutes of the kind described in Specification 21312/14, means are provided for restricting the opening of the parachute until it has fallen clear of the aircraft from which it is launched. In the form shown in Figs. 1 and 2, the restricting-means comprises cords 10 connected to the rigging 3 and to a container 2, so that the spreading of the parachute is restricted by the cords 10, as shown in Fig. 2, until they become taut and break under the stress of the load. In modifications, the restriction is under the control of the pilot; for example, tongues 14, Figs. 3 and 4, attached to the periphery of the parachute 13 are lightly secured together by stripping pieces 15 connected to a cord 17 leading to the pilot; or a series of tapes may connect the periphery of the parachute to a central releasing- device under the control of the pilot. In order to prevent the sensation of a dead drop, frills 52, Fig. 14, may be attached to the rigging and a small parachute 54 may be added. Further, an auxiliary parachute 55 may be provided as described in Specification 105,944. Specifications 24594/14 and 8649/15 also are referred to.
