y ARTIFICIAL LIMB;

- of a leg removed at the hip of a person,

which comprises means whereby the same will be readily attached and conveniently supported by the person and will permit of movement thereof substantially similar to the movement of a persons leg from his hip, by motion from the body ofthe person.

Other objects and advantages will present themselves as the nature of the invention is better understood, reference being had to the accompanying drawings, in

which Figure 1 is a front elevation illustrating the application of the improvement.

Fig. 2 is a side elevation thereof.

Fig. 3 is a rear elevation.

Fig. 4 is a sectional view through the improvement, approximately on the line 4 4 of Fig. 1.

Fig. 5 is a substantially similar sectionalr view but showing vthe arrangement of parts as when the body of the wearer is bent'to break the joint between the artificial leg and the ysupport therefor.

- Fig. 6 is a sectional view through the improvement, approximately on the line 6?6` of Fig. 2.

Fig. 7 is a perspective view of the improvement looking toward the inner side thereof.

The supporting element or socket of the improvement is constructed of some pliable material, preferably including an outer portion constructed wholly of leather and an inner cushioning member. The socket 10 has its inner face open, and its inner edge at the upper corner thereof. extended to provide a strap 11, its opposite upper corner also extended and provided with a buckle 12 to receive the strap, whereby the device may be secured upon the person of the wearer and the stub at the portion of the body from which a limb has been removed is received in the socket. It is, lof course, to be understood that the socket is shaped Specification of Letters Patent.

to snuglyY receive the hip 'portion of the wearer and that the inner edge thereof is disposed to one side of the crotch.V Thus the socket is not contacted by the remaining leg of the wearer or by any of the parts of the wearer except the hip and stub of the leg, the abdomen to one side of the center of the body, the back, and, of course, thewaist around which the strap 11 is arranged. Both the abdomen and the back of the wearer are braced by a metallic band which is rounded around the outer portion of the socket 10 adjacent to the upper edge thereof, the said rounded band being indicated by the numeral 13. The metallic band is secured to the flexible socket in any desired or preferred manner and has its ends terminating in a line with the outer edge of the socket at the open side thereof. To the ends of the band 11 is secured a metallic 'casting in the nature of a strap 14 which conforms to the shape ofthe socket and is, of course, arranged at the open side thereof. The 'curved or roundedstrap 14 may be integrally formed with the band 13 and is secured to the socket 10. The lower and central portion of the strap 14 is thickened as at 15 and the said thickened portion is provided with a transverse extension 16 arranged directly below and corresponding to the shape of the bottom portion of the socket 10. This extension 16 is extended around the outer side of the socket as `1 ndicated by the numeral 17 Y and is secured approximately centrally to the band V13. The

extension, at the juncture of the portionA 17 therewith is provided with a widened or thickened portion 18. vConnected to the extension y17, the band 13and to the socket 10, at the front thereof is a metallic strap 19 that conforms to the shape of the socket.

Of course, this strap 14 may be integrally' formed with the remaining metallicv'elements above recited. The widened''rthick ened portions 17 and 18 provide the metallic reinforcements for the socket with the leg are braced by a metallic strap or band 23 that is secured t0 the artificial limb.

On the strap 19, adjacent to 'the connection thereof with the extension 1G is an` outwardly projecting bifurcated lug 24, In the bifurcated lug is pivoted, as at 25, a rod 26 that is adjustably received in and secured to the hollow outer portion of a link 27. 'Ihe link 27 isv hingedly connected, asat 28 to a second and fiat link 29, the last mentioned link being h-ingedly secured, as at 30 in the hollow portion of the artificial limb 22, at the front of the said limb. The link 30 isfprovided with an elongated slot 31 which receives therein the notched shank 32 of a latch member 33. T he latchhas its outer end provided with a head 34 that is arranged eXteriorly oftheslottedface plate of the keeper 35 for the latch. In the keeper isak spring 36 which bears against the latch, nomnallyfinfl'uencing the same in one direction. The head or outer end of the latch has itslower edge arranged at an angle as indicated by the numeral 37.

When the devi-ce is strapped upon the person of the wearer, in a manner 'as hereto fore described a pressure of the wearers body in a forward direction, with the outer end of the limbl resting upon the ground, will break the joint between the links, causing the latch to disengage the link 30. When the wearer brings his body back to normal vertical position the links will be swung to alining position and the. catch will engage with the link 30, thus locking the leg vertically with respect to the body of the wearer. y Y

It is believed, from thel foregoing description, when taken in connection with the drawings, the simplicity and advantages of the construction will be readily apparent without further detailed description.

Hav-ing thus described the invention, what is claimed as new, is

l.y In a device of the'class described, a flexiblel socket, attaching means therefor, curved metallic brace members secured to lsaid socket, an artificial limb pivotally con- ,nected to said brace, jointed members pivoted to the brace and to the limb, and means for engaging one of the members to hold both of said members in normal longitudinal alinement.

2. In a device of the class described, a flexible socket, attaching means therefor, curved metallic brace members secured to said socket, an artificial limb pivotally connected to said brace, jointed members pivotally connected to the brace and limb respectively, and spring influenced means for engaging one of the' members to hold both of said members in normal longitudinal alinement. 3. In a device for they purpose setforth, a flexible socket having an open side, fat-j taching means forfsaid socket, curvedvmetallic brace members secured to the outer ranged at the outer edge of said` socket, an artilicial limb pivotally connected to other ofl vface of'said socket, one of which beingv arjustably connected to one ofthe braces, and,

spring influenced means yon the limb for engaging with one of the links for holding both of said links in normal longitudinal alinement. Y v

4. In -a device ofY the class described, a

- iexible socket having an open side, an attaching strap adjustable on said socket, curved metallic brace members secured to the outer surface' of said socket, one of which being arranged at the upper edge,

thereof, another at the open end thereof, a other at the side thereof and the last at the front thereof, an artificial limb pivotally secured to the brace members at the lower portions thereof, jointed links one of vwhich being hingedly connected in the limb, the other being adj usta'bly pivoted to the center brace member, one of said links having a slot therethrough, and a springinfluenced catch carried by the limb received in said slot to hold the links in normal longitudinal alinement. Y

In testimony whereof I affix my signature.
