Title: Improvements in quickly detachable harness fasteners
IPC: B64D17/32
Filed: 1954-07-28
Abstract: 755,899. Strap fastenings. HOLM, R. L., DALGLISH, J. J., LAGER, E. W., BEER, W. A., and MALONEY, A. C. July 28, 1954, No. 22068/54. Class 44. In a quickly detachable fastener for use with a harness clip B having an apertured end, the fastener includes a latch A having two pivotally connected parts 21, 48 which define a socket to accommodate the apertured end of the harness clip, a parachute key 63 removably secured to one of the latch parts 48 to extend through the aperture of the harness clip when the clip is in the socket, and a pin 46, slidably supported in one of the parts 21, and engageable in a recess in the other of the parts 48 to hold the parts from relative pivotal movement. The latch part 21 is a body portion to which the harness is connected through a slot 23. To this body portion the second part 48, which is an arm, is pivoted, the arm having legs which straddle a barrel 29 on the body portion. The barrel contains a piston 42 which is formed integrally with the pin 46 which is urged into engagement with the recess in the latch arm by a spring 49. The piston is moved against the spring, to release the latch arm,. by gas pressure supplied through a connection 39, e.g. from a seat ejection cartridge. The gas is supplied to the rear of the piston and passes through one or more apertures 50 in the piston to exert greater pressure on the face than on the rear to move the piston. The socket for securing the apertured end of the clip B consists of a pair of aligned notches 61, 62 one in the latch arm and one in the body portion. The key 63 is intended to be connected to the opening cord of a parachute so that the parachute is automatically opened if the harness is released by firing the seat ejection cartridge. It is tapered in cross section and fits in apertures in the latch arm and body portion to retain the clip B in position when the latch arm is locked by the pin 46 to the body portion. When the latch arm is released, its separation from the body portion allows the clip B to fall away from the end of the key to release the harness, but the key remains locked to the latch arm by means of a pin 59 which passes transversely through the arm and intersects the key securing aperture in the latch arm. The key has a peripheral groove 69 which when engaged by the pin 59 locks the key to the arm. The key can be released by manually rotating the pin 59 by means of a handle 71 which straddles the arm and which is connected to the pin. This rotation aligns an arcuate notch 75 in the pin with the key, this notch coinciding in shape with the key, in one position of the pin, so that the key is free to move. In a modification, the latch arm is connected to the body portion by a pin attached to a lanyard instead of to a piston and the arm is released by a pull on the lanyard.
