HIS HTTO RNEYS I may in some cases connect the thigh to the4 rear or heel part of the foot (say the cap c) by a spring and strap, as dotted at Fig. 2, and dispense with the back strap g of the knee joint.

The sp1-in gs (/X tX Work withinthe metal loop i or strap g2 h2, respectively, and an adjustable sliding bridge-piece g3 h3, preferably made of leather, regulates the strength or resistance. of the spring g or hX.A A similar leather piece g4 7L, Fig. 4, lines the end of the metal loop,

and in the case of the rear spring g3 a collar g5 and leather or other buffer g6 are ixed on the central spindle to limit the action of the spring, or a rubber buer may be used instead of a metal spring, as seen at (/XX, Fig. 5,

The studs or pins a and d, forming the pivot and stop of the anklejoint, may be somewhat barrel-shaped or made with globular enlargement at the center, as shown detached at Figs. 6 and` 6, to allow lateral and diagonal flexion, as Well as the ordinary forward flexion, of the ankle-joint in case the foot e is pressed down on a small stone or uneven surface. In some cases 'the anklejoint pin a and stop-pin d may be fixed to the foot e, as seen at Fig. 3b, the

\ springs g hx'heing reversed and passing into a cavity in the foot e and the bearing c c.' c2 being fixed to the side irons of the shank. This Fig. 3" shows the side ironand the plate c combined in one piece, and in some cases Where'there isno room for the springs g 71, and their adjuncts above the foot (in the case of Very low` amputation) l use one central spring-link hXX, Fig. 2, in a cavity in the front of the foot and a lever tx, pivoted to the stoppind. This lever rests on the joint-pin a and Works around it when the anklejoint is bent until' the end of the lever is stopped by a projection eX on the plate c or foot e, and further motion is checked by the spring hXX, which bears against the under side of the projection e, and this cheeks the joint just before the" stop-pin d comes into contact with the bean ing c. In all eases these springs g hX hXX act `as eornpressonsprings and are already compressed to resist the extension of check straps or links which hold the joint in place, and this takes a great strain oit the joint-pins and y bearing-plates.

The front part of the foot e, Whether in the` form of a wooden block or shell-piece of aluminium or otherwise formed, is shorter than usual and inclined upward at e from the ball ot' the foot toward the front or point, and this part of the foot is inclosed in an inflated aix cushion 7c., forming the toe of the foot The foot e is preferably covered with a-ruhber cap c2, which protects the saine and also insures an air-tight joint with the pneuniatiel pneumatic case is at both toe and heel l have a pneumatic footV 7s with a Wooden or other core e therein, and there will be no sharp angle bearing upon the cushion and' likely to wear the saine.

kx is the initiating-tube for the cushion..

The heelot' the foot e is mortised or groqved, as seen at Fig. 3, and a block of rubber e' (see also Figs. l, 2, 3, 3, 4, and 7) is let into the groove or mortise to form an elastic cushion for the heel, the. groove ih- Which is tapered inward to fit the taper of the dovetailed part of the block e. (Shown at Fig. 3f.) The upper part ot' the foot is hallowed out for the bearing and to allow free play ot the foot e, the bottom of the shank tting into the foot. (See Figs. 1, 2, and The shank is formed of the side irons Zi, before named, and at oertain parts is made with side projections li er extensions in Width, to which bands or halbands of metal l, Fig. l, may be riveted at ZX to complete a frame upon which canvas or other suitable material may be stretched or built 'to form the leg. These projecting parts b', may alsobe made with upwardly-extend ing points or lingers b, upon which the easing may be suspended by suitable sockets or pockets, or Wooden shell-pieees may be used or other partsl or sections forming the shape' ot' a natural limb. The extensions o allow of the riveting ot' parts to the side irons l) without weakening the latter, which have really to support the weight put on the leg or foot,

IOC)

and the points b2 allow for readily removing the casin g to get at the inclosed Working parts for adjustment or repair. The side irons?) are jointed to extensions or further `side irons b3 on the thigh-cover for thigh-pieee, and the irons b3 are providedwith a stop b4, the upper end of the shank side irons .7i being provided with a cam-shaped piece b5 to` prevent the knee-joint thus formed from bending in- IIO ward-thatis,backward-onitspi'votl. (See y (seen dotachedat Fig. l0,) and along the other edge with a removable lisp or tongue n2, having holes it, into which the hooks enbetween the projections b'.

esatto gage. This dispenses with the usual lacing, which is a tedious operation. The inner upper edge of the thigh-coverf is provided with a pulley o and guides o', Fig. Il, under which a suspending-cord p is passed, and this cord p is attached to straps or bands or webbing q, connected to a yoke, preferably of webbing o', provided with a loop q2, through which is passed the arm and shoulder at the side of the body opposite to the artificial limb, one of the straps q passing over the second shoulder. (Sec l2.) The two straps q, connected to the same yoke q, are passed also at liront and baclr of the second shoulder and connected together at their lower end, where they are attached to a spring-buckle g4, pivoted at g5 to the outer side of thethigircoverf. This forms a if'ery easy-itiing efficient snpport for the artificial limb, which is thus hung directly from the shoulder immediately above it, and the raising, of the limb by this shoulder is quite natural when walking. In the case of amputation of both legs q2 might be dispensed with.

The side irons Z) and b3 may be made hollow or tubular, and those of the shank may bc made in parts, so as to be adjustable in length, if desired. This is effected, as seen at tig. 2, the two parts being connected together by a plate h6, which can be replaced by a longer plate h6, (seen detached at Fig. 22",) if desired. The side irons h3 are made with a series of rivet-holes b3, so that they can be let down upon the cover f, as seen at Fig. if), to lengthen the thigh, if desired. rlhose of the shank are so arranged also as to carry more weight at the back of the kneejoint pin than at the front, and thus they will swing,r forward automatically at every step in walking'.

I propose to fasten a strip or strips of lcatherj"i around the top of the rear part of the thigli-coyerfto strengthen the saine.

The bnelrle i', which I vhave invented for the suspension of thelimb, (or for other parts requiring such a buckle,) is made with the prong or prongs i" in one part with the' frame (see Figs. lb and lll) and, if desired, in one with a spring' r9, holding it or them to the frame r.

For a spring-brittle, seen at Figs. l2, l5, and l5, I lit a spring s around each prong v" or around all the prongs r', Fig. I7, bearingT against the crossbar r2 and against a looped strap r, through which the prongs pass and which is connected to one of the ends or parts "to be joined by the buckle, the frame frbeing Afastened, as usual, by the prongs 1" to the other end or part, that the weight oi" the limb is suspended on. the springs .v

I sew the cover ff of the limb to both sides of the side irons, Aas seen at Fig. l, and I pro tent the` stitching by stripsofleather i', placed This prevents the irons from working up and down and allows the cover supported by the stitching.

to be in some cases entirely I claim as my invention;-
