A. E. TULLls ARTIFICIAL LIMB Jan. l0, 1933.

Filed Deu. l5. 1951 Patented Jan. 10, 1933 UNITED STATES Amos E. TULLIs, or MrNNnAronrsivrINNr-sora Aa'rrrrcran 131MB Application mea December 15.11931. seriai No. 581,208.

This invention relates to artificial limbs.

An obj ect of the invention is the provision of an artificial limb having a plurality of air cushions so placed that they will take up the irregularities in the amputated member to provide a yielding supporting surface for said amputated limb.

A further object of the invention is the provision of an artificial limb having a socket portion provided with a plurality of passages in the side walls thereof and an annular groove located externally of the socket, said socket being received by a shell, an elastic tube received within the groove and adapted to be iniiated for forcing the tube through the openings to provide cushions at particular points in the socket for aiding in comfortably supporting an amputated member.

This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawing forming a part of the specification; nevertheless, it is to be understood that the invention is notconned to the disclosure, being susceptible of such changes and modifications which shall define no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:

Figure 1 is a view in elevation of an artiiicial limb constructed in accordance with the principles of my invention,

Figure 2 is avertical section taken along the line 2 2 of Figure 3, and

Figure 3 is a top plan view of the socket shown in Fig. 1 with parts broken away.

Referring more particularly to the drawing, 10 designates a substantially rigid body portion of an artificial limb which has a shell 11 surrounding the same and secured thereto, as shown in Fig. 2. A socket, gen* erally designated by the numeral 12, which is adapted to receive the amputated portion of a limb, rests upon the upper end 13 of the hollow body portion 10.

The socket is provided with a plurality of spaced openings 14: at predetermined points in the socket for a purpose which will be presently explained. An annular groove 15 encircles the exterior of the socket and spans ,the annular tube 25.

the openings 111 so that a peripheral portion 16 ofA the openings 14; will be slightly thinner than the body portion of the socket 12.

:Aninner liner in theformof a sleeve20 issuspended from the upper end of the socket 12 andy projects loosely into the socketsand proJect-s partially into the upper lend of the hollow body portion 10 ofthe artificial limb. The liner at its upper end is providedwith a iange 21 located exteriorly of the socket and 6@ is disposed between the shell 11 and the outer wall of the socket. The liner is made of flexible material suchas fabric orl it maybe made 'of any form `of elastic material, such `4as rubber, if desired., w 'i x An .endless elastic tube 25 is located within the annular groove Y15. This tubemay be made of any material such as rubber :which will permit portions of the tube toexpand when filled with air in order to force Vthe portions of .the vtube through the openings 14 to` provide airl cushions as indicated at 26. A tube 27 `formed of any hard material is connectedwith an opening in the tubular valveto permit the tube 25 to be filled with air in any well known manner. A liner 30 formed of. fabric is mountedA in lthe groove 15 `and embraces the inner face of thevtube ymember 25andis,provided with the usual, 75

25. The liner is soconstructed that it will be lforced through'the openings 14 whenvthe proper `amount of air has been supplied to A second liner 32,embraces the outer face of the annular tube 25 and flatly contacts with theinner wallof the sleeve 20, after which air is suppliedl through the feed 27 until the portions of the annular aintube 25 have moved through the openings .14: 1n the socket 12for engaging andsupporting` thek amputated member. At this time theliner 30 is moved inwardly .through said 95 openings and in engagement with the sleeve 1. An artificial limb comprising a substan'; tially" rigid socket member having openings in the side walls thereof, a shell embracing said socket, a liner formed of flexible material suspended within the socket, an elastic tube located between the outer wall of the socket 5 and the shell, valve means through which air may be forced for inflating the tube so that the portion of the tube within the openings will be inflated and provide cushioning means for the amputated member.

2. An artificial limb comprising a substantiallyl rigid socket member' having openings in the side walls thereof, a shell embracing said socket, a liner formed of flexible material suspended within the socket, an elastic tube located between the outer wall of the socket and the shell, valve means through which air may be forced for inflating the tube so that the portion of the tube within the openings will be inflated and provide cushioning means for the amputated member, a second liner located between the inner wall of the elastic tube and the outer wall of the socket.

3. An artificial limb comprising a substantially rigid socket member having openings in the side walls thereof, a shell embracing said socket, a liner formed of flexible material suspended within the socket, an elastic tube located between the outer wall of the socket and the shell, the inner face of the tube adacent the openings being unsupported, valve means through which air may be forced for inflating the tube so that the portions of the tube opposite the openings will project inwardly through the openings and form cushioning means for an amputated member.

4. An artificial limb comprising a substantially rigid socket member having openings in the side walls thereof, a shell embracing said socket, a liner formed of flexible material suspended within the socket, an endless elastic tube located between the outer wall of the socket and the shell, valve means through which air may be forced for inflating the tube so that the portion of the tube Within the openings will be inflated'and provide cushioning means for the amputated member, the outer wall of the socket being provided with an annular groove to receive the annular elastic tube.

5. An artificial limb comprising a. substantially rigid socket member having openings in the side walls thereof, a shell embracing said socket, a liner formed of flexible material suspended within the socket, an endless elastic 'tubelocatedbetween the outer wall of the socket and the shell, valve means through which air may be forced for inflating the tube so that the portion of the tube within the openings will be inflated and provide eushionin g means for the amputated member, the outer wall of the socket being provided with an annular groove to receive the annular elastic tube, and a liner located exteriorlT of the tube and held in place by the shell.
