JAMES T. BRACHT, 01? MEMPHS, TENNESSEE.
ARTIFIIL LIME.
To all whom it may concern.'
Be it known that JAMES T. Bnnoiir, a citizen of the United States, reslding at Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful improvements in Artiicial Limbs, oil which the following is a specification.
The present invention relates to improvements in artificial limbs, and relates more particularly to the ankle joint thereof, one object oi the invention being the provision of a joint that permits of a nathral movement of the joint, and which is further provided with means whereby the same is automatically lubricated to prevent squealiing during the movement of the limb.
A further object of the invention is the provision of an ankle joint, which simple, durable and inexpensive in construction and which is thoroughly eiiicient and practical in use.
With the foregoing and other objects in view that will appear as the description proceeds, the invention consists in the construction and combination of parts as particularly pointed out in the claims.
In the accompanyin drawings 2-Figure 1 is a side elevation of t ie lower portion or' an artificial limb in section with the present joint in use. Fig. 2 is a front elevation of the joint per se. Fig. 3 is a section on line of Fig. 2. Fig. 4 is a, view of a modified iorm. Fig. 5 shows tivo parallel rods passthrough'the Jfoot. Referring to the drawings, the numeral 5 ignates the foot and 6 the lower section an artilicial limb or leg, the ankle joint being employed as the connection between thc two. I
1lfhe joint comprises essentially the meinlier S5, which fits within and engages the section (3, and provided with the transversely die used cylindrical end 9, which is providezl with the cylindrical bore 10. The upper l is threaded as at 11 for the reception of nttachmg nut 12.
c member 13 of the joint is provided. with the enlargement 14, having 'the cen- Specicaton ci Le tterslatent.
Application filed zFebruary 20, 1915.
l): tent-ed Got. 5, i915.
Serial No. 9,756.
tral recess or slot 15 for the reception of the end 9 of the member 8, the two cylindrical members 1G thereof heineprovided with cylindrical bores 17 that aline and also aline with thcfbore l0, so that the tubular member 1S may.' be passed through all the bores from one of the members 1G. This member 18 is provided with the annular rim or flange 1S of substantially the same diameter as the member 16, and has its opposite end .terminating liush with the outer face oi' ,the other member 16, the same being provided with the interior threads 2O for the reception of the securing screw 21, whose head iits exteriorly ot the adjacent mem- 'ber 1G and is of substantially the same di- I26 are en'lployed.
From the foregoing description, it is evident ,that a simple and durable ankle joint is provided and that with thelubricating feature a great objection to joints-is overcome.
lVhat ls claimed, as new, is'; l
1. An ankle joint for artilicial limbs, including two cooperating members, one of which is provided with a single hollow cy.- lindrical end, while the other of which is provided with two hollow cylindrical ends 'for axial alinement with the other hollow end, and 'a tubular -fastening and bearing member iitting in all the hollow ends and upon which the en ds rotate.
2. ,An ankle joint for artificial limbs, including a foot engaging and a lower limb engaging' mei'nbcr, a hollow cylindrical knob carried by one member, two hollow cylindrical knobs carried by the other member,
said knobs being spced apart to permit the insertion therebetween and axially alined therewith of the first knob, a tubular member smiled :it one end and having :1n annular rim :1t the sealed end said tubular member fitting in the hollows of the knobs und forming` :l bearing fon the knobs, and a locking member nsertible in the open end of the tubular member for locking the parts assen bled.
