By loosening the set screw 6, the leg may be The portion 3 is held from movement from its adjusted lengthwise of the horizontal portion 3,

which portion is disposed in a chord of the arc of the tread of the arcuate portion 4 of the foot of the stilt. By adjusting the leg from the middle toward one end of the portion 3, the resilient action is reduced, and the device is adapted for a heavier person.

When the operator, while walking desires to raise or lower the foot support, he will raise his foot against the strap 18 with suflicient pressure to swing upwardly the portion 11 against the holding efiect of the U shaped spring 12. When this is eiTected, as shown in Fig. 6, the operator may with his foot raise or lower the foot support. Upon adjusting the foot support to the desired position, the operator presses downwardly on the portion 11, thus moving the latter down- 'wardly so as to effect a gripping action or the members 14 and 15 upon the leg portion 1. This swinging downwardly of the portion 11 will again engage the spring 12 with the leg portion 1, as shown in Figs. 2, 4 and 5. The stilt may then be used in the usual manner for walking.

By pivoting the leg gripping members 14 and 15 to the portion 9 of the foot support, and providing the members with gripping surfaces of substantial area, said surfaces will lie flatwise against the leg, when downward pressure is exerted on the portion 11 of the foot support, thereby avoiding liability of the gripping members indenting or marring the leg, when the latter is clamped thereby.

I do not limit my invention to the structure shown and described, as many modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.

What I claim is:

1. A stilt having a leg, a foot support movable upwardly and downwardly relative thereto, and two gripping members pivoted to said foot support and disposed respectively at opposite sides of said leg and having gripping surfaces of substantial area which lockingly grip said leg when said foot support is swung downwardly, and which are released from said leg when said foot support is swung upwardly relatively to said leg.

2. A stilt having a leg, a foot support movable upwardly and downwardly relatively thereto, two gripping members pivoted to said foot support and disposed respectively at opposite sides of said leg and having gripping surfaces of substantial area which lockingly grip said leg when said foot support is swung downwardly, and which are released therefrom when said foot support is swung upwardly, and means normally yieldingly holding said foot support in the gripping position.

3. A stilt having a leg, 2. foot support movable upwardly and downwardly relatively thereto, two gripping members pivoted to said foot support on horizontal axes and disposed respectively at opposite sides of and adapted to lockingly grip said leg when said foot support is swung downwardly, and releasable from said leg when the foot support is upwardly swung, and a spring fastened to said foot support and having means, when the latter is swung downwardly to the leg locking position to releasably embrace opposite sides of said leg for holding the foot support in the locking position, said spring being released from holding engagement with said leg upon a predetermined force being exerted upon said foot support tending to swing the latter upwardly.

4. A stilt having a leg, and provided with a foot having an arcuate tread portion and a horizontal portion extending from one end of said arcuate portion toward the other end thereof, said leg having its lower end portion adjustable lengthwise of and provided with means for being rigidly attached to said horizontal portion.

5. A stilt having a foot provided with an arcuate tread portion, and a resilient horizontal por tion between the ends of said tread portion, and a leg having its lower end portion rigidly fastened to and supported by said resilient horizontal portion.

6. A stilt having a resilient bow shaped foot having resilient horizontal portions extending toward each other from the ends of the bow, one of said portions resting upon the other, and a leg adapted to support the Weight or" the user and having its lower end portion adjustable lengthwise of the upper one of said horizontal portions and having means for being rigidly fastened thereto in the position to which it is adjusted thereon.

7. A stilt having a foot comprising a strip of resilient material provided with an arcuate portion and a horizontal portion extending from one end of said arcuate portion toward the other end thereof, and a leg adapted to support the weight of the user and fastened rigidly to said horizontal portion.

8. A stilt having a foot comprising a strip of resilient material having an arcuate tread portion and a horizontal portion extending from one end of said arcuate portion toward the other end thereof, and a leg adapted to support the weight of the user and adjustable on and lengthwise of and having means for being rigidly fastened to said horizontal portion.
