ARTIFICIAL LEG.
Application filed November 9, 1883.
To all zohonaitmaly concern: I Be it known thatKIlvs R. OoLLINs, of Hart, in the county of Oceana and State of Michiputations, designed to cient, and durable leg, as hereinafter fully described.
Reference is to be had to the accompanying responding parts in all the figures.
Figure l is a side elevation of my improved artificial leg. Fig. 2 is a sectional elevation, and Fig. 3 is a detail of the ankle-joint device.
The thigh-socketa and the lower leg-section, b, are made of strong leather 0, and covered with rawhide d, the latter being painted with water-proof paint, which makes a lighter,
The foot, consisting of the. main section 0 and toe-seotionf, is of wood or any approved material, with a leather sole,
when walking, and to restore it to the normal position when the foot is lifted from the ground. A strong flat rubber spring, j, fitted on the inside of the sole may serve this purpose; but coiled springs may be used instead or in combination with it.
For connecting the foot to the leg at the an kle-joint, a Wood block, 70, is fitted in the lower end of the lower section, b, of the leg, in which the knuckle Z of the anklejoint is secured by two bolts, m, of said knuckle, which extend up through the block and have nuts Izscrewed The pintle 0 of said joint is secured possible insuch legs.
to the foot 6 by the rod p thereof extending down through the foot and made fast by nuts 9 in the socket 8. Each side of the ankle joint-that is, before and behin'dis fitted a spring, 9, to balance the foot on the jointand hold the foot ground.
For the knee-joint a metal bar, If, isattached to each side of the section 12, within the same, and extending upward and through the sides level when raised ofi the spective sections of the leg for permanent attachment thereto. It will be seen that these joints are very substantial and will not have lateral play,'which is to be avoided as much as The pivot to of this joint extends through from one to the other, and a pulley, as, is arranged on it between the two joints, and the suspensory strap y is connected to the leg by passing it through slots of the socket a at z and under the pulley, thus making a simple and substantialconnection, capable of ley as the body of the wearer moves, and preventing any uncomfortable strains as the body acts, and also the leg. 7
The extensor -spring 'a is connected to the I block 7:; in the ankle by a joint, b, back of the anklejoint pivot, and a doubled cord, 0', is stretched from the eye (2 of the upper end up through holes 6, through the lower end of the socket a, a little forward of the knee-joint piv- 0t, and thence the cord is passed through two holes, f, at the back of the socket a,where the two parts of the cord are to be tied to maintain the proper tension on the spring.
It is proposed to cushion the top of the thigh a with pads k fitted to the top of the same, as shown, for upper amputations.
The thigh-socket is provided with vent-holes i, for the circulation of air for ventilation.
Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is- 7 i in front of the Vertical line of the knee-j oint,
