WILLIAM ANDERSON, OF HOLLY SPRINGS, MISSISSIPPI.
APPARATUS FOR FACILITATING WALKING.
Application filed March 29, 1910.
Specification of Letters Patentv Patented Dec. 20, 1910.
Serial No. 552,148.
To all whom it may concern:
Be it known that I, WILLIAM W. ANDER- son, a citizen of the United States, and a resident of Holly Springs, in the county of Marshall and State of Mississippi, have invented an Improvement in Apparatus for Facilitating Walking, of which the following is a specification.
Iy invention is an improvement in that class of leg attachments which are adapted to facilitate walking or jumping.
The invention is embodied in appliances or devices adapted to be secured to the thigh and foot of the wearer, and an intermediate connecting portion formed of springs, which are alternately flexed and extended in the act of walking.
Thus, the essential principle or distinguishing feature of my invention is the adaptation of the springs to serve as levers. The details of construction, arrangement, and operation of the apparatus are as hereinafter described, and illustrated in the accompanying drawing, in which Figure l is a side view of one form of the apparatus as applied to the leg of a wearer. Fig. 2 is a side view of the same showlng the position the spring assumes when the leg is flexed. Fi 3 is another side view showing a modification. Fig. 4 illustrates the operation of the same. Figs. 5, 6, 7, and 8 show other modifications and the operation of the same, as will be hereinafter described. Fig. 9 is a perspective view of another modification. Figs. 10, 11 and 12 are views illustrating the operation of the form shown in Fig. 9.
In Fig. 1, the numeral 1 indicates a springrod which is attached to a foot-piece 2 secured to the front portion of the shoe sole, the upper end of the same passing through keepers on a leg-band 3 and then forming a loop 4 which extends around the rear side of the thigh of the wearer. Thus, there are two side rods 1 having a connecting loop 4-, the leg being adapted to work freely between the parallel portions 1.
In Fig. 2, the le of the wearer is shown bent forward and t e springs 1 are flexed or bent rearwardly to the same degree, thus acting practically as spring levers.
In Fig. 3, the sprin s are formed in two parts, to wit, upper an lower portions 5 and 6, the same being jointed together at 7 opposite the knee-'oint of the wearer. Since when the foot 1s raised, the knee is flexed, it
is apparent the joint 7 permits this movement without resistance. The upper part 6 passes through keepers on the leg-band 8 and then around the rear side of the thigh of the wearer, as in the form shown in Figs. 1 and 2. In Fig. l, the operation of this form of the device is illustrated, the leg of the wearer being shown bent forward and the springs 5 and 6 flexed to the rear or in the opposite direction.
In Fig. 5, I again employ two springs 9 and 10, which are similar to the form shown in Fig. 3 save that both are curved slightly to the rear. The joint 11 in this case is located somewhat lower than the joint shown in Figs. 3 and 4-, or a little below the kneejoint of the wearer.
In Fig. 6, the lower spring 12 is the same as in Figs. 3 and 5, but the upper spring 12 has a forward bend, which serves to increase the elasticity of the attachment. In view of the increased elasticity, this is my preferred form of the invention.
In Fig. 7 the springs 13 and 14 are the same as in F ig. 6, but the lower spring 13 is attached to the toe of the wearers shoe instead of being attached at a point opposite the ball of the foot.
In Fig. 8, the upper spring 15 is the same as in Figs. 6 and 7, but the lower attachment 16 may be composed of practically rigid rods instead of springs,
In Fig. 9, I show another modification in which lower springs 17 and upper curved springs 18, similar to those illustrated in Figs. 6 and 7, are em loyed, but instead of the upper portions 0 the lower spring 17 terminating at the joint 19, whereby they are attached to the upper spring 18, they form a loop 20 which passes around the rear side of the wearers thigh and serves to hold the joints duly spaced apart.
Figs. 10, 11 and 12 illustrate the position this form of the device assumes when in use,
that is to say, when the leg of the wearer is flexed more or less as in walking and running. The loop 20 may be made integral with the springs 17, or as a separate piece.
Thus all the forms of my invention include a lever sprin which renders the de' vice particularly e cient in operation. In other Words, I provide a spring support adapted to relieve, in part, the muscles of the leg of the weight of the body when walkin and incidently the reaction of the spring I I l alds 1n propulsion.
I propose to employ any suitable form of leg-band which may be adapted for the purpose.
W'hat I claim is 1. A leg attachment to facilitate walking, comprising parts adapted to be secured to the thigh and foot of" the wearer, and an intermediate connection including a spring lever, substantially as described.
2. The improved apparatus for the purpose specified, comprising devices adapted to e secured to the thigh andv foot of the wearer, and an intermediate connection including a spring formed of rods arranged on each side of the leg, substantially as described.
3. The improved apparatus for the pur pose specified, comprising a thigh-band and an attachment for the shoe of the wearer, and an intermediate connection between the two which includes spring rods arranged on each side of the leg and adapted to be flexed when Jressure is applied in the manner describe 4:. The improved apparatus for the purpose specified, comprising a leg-band and an attachment for the shoe of the wearer, and intermediate connections comprising rods connected withthe shoe and an upper spring whose lower port-ion is curved between its oint of attachment to the leg-band and its ointed connection with the rods, substantially as described.
5. The improved apparatus for the purpose specified, comprising a thigh-band, and an attachment for the shoe of the wearer, and intermediate connections consisting of two springs which are jointed together at a point adjacent to the knee of the wearer, substantially as described.
6. The im roved apparatus for the purpose specified comprising a thigh-band and an attachment for the shoe of the wearer, and intermediate connections comprising two springs, one connected with the shoe and the other with the leg-band and jointed together, the upper spring being curved from its point of attachment to the thigh-band to its jointed connection with the lower spring, substantially as described.
7. In an improved apparatus for the purpose specified, a leg-band and a shoe attachment, and intermediate spring connections formed of spring rods attached to the shoe, and an upper spring secured to the leg-band and curved forwardly and rearwardly, a loop 20 connecting the upper ends of the lower spring, substantially as described.
8. In an apparatus for the purpose specified, spring rods adapted for attachment at one end to a shoe-sole and constructed at the other end for connection with a legband attachment, substantially as described.
9. In an apparatus for the purpose specified, the combination with a leg-band of a spring secured thereto and adapted for con nection with other springs attached to a shoe-sole, substantially as described.
