Abstract

391,634. Artificial limbs. DAVIES, C. H., 1136, Girard Avenue, Philadelphia, U.S.A. June 20, 1932, No. 17342. [Class 81 (ii).] A hollow metallic artificial limb member is formed by working in stages upon a flat or curved sheet of thin metal, such as aluminium or alloys thereof, to produce a one-piece seamless tubular element, closed at one end, and then shaping this to the configuration of the limb. The metal sheet is spun or compressed over mandrels of progressively diminishing diameter until it assumes first a basin-like form and finally the form of a tube d, having coaxial zones of different diameters along its length. By spinning or compressing over a tapering mandrel f, the open end may be caused to conform to the shape of the limb stump and the tube assumes the form indicated at e. If the limb is to be used, however, with a socket member fitting the stump, shaping of the open end is unnecessary The element d or e is now bent or distorted to correspond with the shape of the limb and is expanded to that shape in a mould. The mould may be a composite one formed of main mould sections and interposed shim mould sections to form a mould of the required length as described in Specification 383,230, [Group XXII], and the expansion may be effected by water pressure as described in Specification 383,231, except that the fluid is introduced through one end only. The mould is shaped to form a V-shaped groove in the knee end for accommodating a check cord and, in the opposite surface, a recess i, the ends of which co-operate with a stop on the inner surface of the front part of the shim element to limit the extent of movement. Projections k may also be formed through which holes are bored for the pivot bolt which may be fitted with ball bearings. A covering, for example, of artificial cellulosic material or a plastic material with a nitrocellulose or cellulose acetate base, may be applied as described in Specification 383,231. For example, a softened tube of the material may be stretched over the limb and allowed to contract and harden. The colour may resemble natural skin.
