OORNELIOUS COLLINS, OF ALBIA, IOWA.
IMPROVEMENT IN ARTIFICIAL LEGS.
Specification forming part of Letters Patent No. 193,396, dated July 24, 1877; application filed J une 25, 1877.
To all whom it may concern Be it known that 1, Continuous Counts, of Albia, in the county of Monroe and State of Iowa, have invented a new and Improved Artificial Leg, of which the following is a specification The present invention relates to improvements upon that class of artificial legs shown in a patent granted jointly to myself and to J. H. McUalla, September 28, 1875, No. 168,140; and the invention consists in a novel construction of the ankle-joint, whereby a perfectly free articulation is allowed without noise, as will be hereinafter more fully described, and then pointed out in the claim.
In the annexed drawing, Figure 1 is a side elevation of my improved limb. Fig. 2 is a sectional view of the limb. Fig. 3 is a bottom view of the foot.
Similar letters of reference indicate corresponding parts.
The letter A designates the thigh-socket; B, the lower-leg section; 0, the ankle-block, and D E the two sections forming the foot.
The thighsocket is formed of stout leather, which is carefully crimped upon a form made from a cast of the natural limb. This socket A has rigidly secured to it two metal straps, a a, which are pivoted at b to metal straps c, that are rigidly secured to the lower leg B and ankle block (J. The section B is made of leather criniped upon a former, and suitably secured to the block 0.
The lower end of the block (3 is curved, as shown, leaving a reduced bearing, which will allow a free motion of the foot forward and backward, as well as laterally. The front concave surface of the block 0 rests upon a cushion, d, and is held down thereon by means of ajoint, 5, formed of two bolts, 0 e. The joint thus formed will allow free play, and the cushion d will prevent shocks in walking.
In rear of the joint 2' is a hook, G, which is connected by an eye-joint with a bolt, f, fixed into the block 0. The hook Gr entersa recess made through the foot-section D, and engages loosely with a pin, j, fixed into this section. This hook-joint also allows the foot to articulate forward and backward, as well as laterally.
The bottom of section D is arched out and the space filled with hair, or some other suitable material which will prevent noise in walking and afford elasticity. The cushion thus formed is covered with a piece, P, of leather, which forms-the joint for the front section E. A flat india-rubber key, is, and a spring, 8, complete the toe-joint. In practice I shall inclose the foot and ankle in an india-rubber skin.
Fig. 2 shows a spring, T, connecting the thigh and lower-leg sections. This knee-spring is a strong strip of india-rubber, fastened in such manner that it will act to straighten the leg when flexed.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of the hook G and pin j with the ankle-block U, foot-section D, linkjoint 'i, and rubber cushion d, substantially as herein set forth.
GORNELIOUS COLLINS.
