Abstract

982,527. Artificial limbs. CHAS. A. BLATCHFORD & SONS Ltd. Sept. 18, 1963 [Sept. 20, 1962], No. 35795/62. Heading A5B. An artificial limb comprises an upper part, a lower part, a connection between the parts for permitting relative flexion thereof, and pneumatic means for controlling the relative motion of the two parts, connected to the two parts, the pneumatic means including a cylinder connected to one of the said parts, a piston movable in the cylinder and connected to the other of the said parts, the cylinder having two end walls, and means for adjusting the piston stroke without varying the clearance between the upper and lower faces of the piston and the adjacent cylinder end wall at the ends of the piston stroke. An artificial leg comprises thigh 1 connected to shin 2 at pivotal knee axis 3. The pneumatic control means 5A comprises cylinder 8 pivotally connected to shin 2 and a piston comprising parts 7A, 7B, connected to thigh 1 by rod 6A. Part 7A is integral with rod 6A and part 7B with sleeve 6B, which is screw-threaded on rod 6A such that the position of sleeve 6B on rod 6A can be varied to vary the piston stroke and the amount of leg extension without varying the clearance above and below the piston at the ends of the piston stroke. On extending the leg the piston moves up in cylinder 8 and gas is exhausted from space 23 and passes to space 24 via a valve, and on bending of the leg gas is exhausted from space 24 and passes to space 23 via a different valve. The valves may be adjustable needle valves and they may, for example, be adjusted so that extension of the leg is subjected to more resistance by the control device than bending of the leg.
