STILT.

SPECIFICATION forming part of Letters Patent No. 514,600, dated February 13, 1894.

Application iiled March 30, 1893- Serial No. 468.328. (No model.)

To cir/ZZ whom t may concern:

Beit known that I, WrLLIAM J. JOHNSON, of Englewood, in the county of Cook, State of Illinois, have invented certain new and use` ful Improvements in Stilte, of which the following is a specification, reference being had to the accompanying drawings.

The object of myinvention is to produce an improved and serviceable stilt by which the step may be readily adjusted to any desired height, and by which the mechanism for fastening the stilt to the body of the wearer may be likewise adjusted to suit diierent people.

In the accompanying drawings, Figure 1 is a side elevation of my stilt. Fig. 2 is a front elevation thereof. Fig. 3 is a central longitudinal section, showing the relations of the dierent parts to the main support or pole. Fig. 4 is a detail view of the leg strap and connected mechanism.

Referring to the gures on the drawings: 1 indicates a support or pole of any suitable length and of any desirable material, preferably wood. It is provided on one side with obstructions as upwardly opening notches 2 and upon the opposite side with graduated apertures 3.

et indicates a step, preferably made of metal, and having an aperture 5 for the admission of the pole and a longitudinal slot 6 for rendering it lighter and for adjusting the foot strap 7, which is, for this purpose, provided with a spreader or stretcher S, at one end.

9 indicates a thumb screw back ot the step.

10 indicates athumb screw at the other end, which serves to securea metallic spring 12 in place and also to secure the end of the foot strap, as illustrated.

In practice, the step is slipped over the end of the pole and is adjusted in piace by the slipping of the springint the notches 2, provided for it. The thumb screw 9 may be employed as a means ot' assisting the firm adjustment of the step when in place. lfVhen mounted upon the pole, the front edge of the recess 5, of the step is firmly secured against the side of the pole, so that thespreader of the foot strap is secured firmly in place and that part of the device is ready for use.

iVhen it is desired to adjust the step, all

that is necessary is to loosen the thumb screw 9, and to slip the step into the required position.

13 indicates a frame or box adapted to iit closely to the pole. It is provided in its rear wal] with athumb screw 14, which, entering the apertures 3, serves to adjust the box in any required position upon the pole. The front of the box is provided with a plate 15 in which is a dovetailed recess 16.

17 indicates a leg strap plate provided with a dovetailed projection 1S adapted to lit into the recess in the plate and to be securely fastened therein against dislodgment by a lateral strain upon it. Upon the leg plate is secured by any suitable means, as by rivets, a leg strap 19, provided with suitable fastening mechanism, as for instance, a buckle 20.

In practice, when the step has been adjusted to the required height and the box has been in like manner adjusted to suit the convenience of the wearer, the leg strap is bound upon the legof the wearer. In adjusting the stilts all that is necessary for him to do is to put his foot upon the step and slip the dovetailed projection upon the leg plate into the dove-tailed recess in the box plate, when the device is iirmly secu red in place. In remov ing the stilts all that is necessary is to remove the foot and slip the dove-tailed projection on the leg plate out of the recess.

I do not confine myself to the details of construction herein described, because they may be varied in many respects without departing from the scope of my invention.

What I claim is- 1. In a stilt, the combination with a pole having obstructions, a step movable thereon, a spring upon the step adapted to engage with the obstructions, a recess in the step for the admission of the pole, a strap secured to the outer end ot the step and having a spreader adapted to enter the recess and to be secured therein against the pole, when the step is secured in place, substantially as specified.

2. In a stilt, the combination with a pole provided with obstructions'of a step having a spring to engage the obstructions, a recess in the step for the reception of the pole, and a set screw in the rear of the recess to assist IOC in the adjustment of the step upon the pole, substantially as and for the purpose Specified.

3. ln a stilt, the combination with a pole and step, of a box adjustable upon the pole, a lesr strap thereon, and a set screw in the box whereby it may be securely adj usted upon the pole, substantially as specified.

4. In a stilt, the combination with a pole, of a box adj ustably secured thereon, a dovetailed recess in the face of the box, and a leg,r plate provided with a dove-tailed projection and a strap, substantially as and for the purpose specified.

5. In a stilt, the combination with a pole, of an adjustable box, and a leg strap, and detachable connecting mechanism, substantially as specified.

` 6. In a stilt, the combination with the pole yprovided with graduated recesses, and step,

WILLIAM J. JOHNSON.
