IMPROVEMENT 1N sTlLTs.

Specication forming part of Letters Patent No. 137,869, dated April 15, 1873; application iilcd February 12, 1873.

To all whom it may concern:

Be it known that I, GEORGE J. STEVENS, of Charlestown, in the county of Middlesex and State of Massachusetts, have invented. a new and useful Improvement in Stilts; and do hereby declare the same to be fully described in the following specification and represented in the accompanying drawing, in which- Figure l represents a side elevation, and Fig. 2 alongitudinal section, of a stilt, constructed in accordance with my invention.

The object of my invention is to provide a simple, cheap, and durable stilt for the exercise and amusement ot' children and others, one which can be readily adjusted and maintained in any desirable position.

I am aware that the combination of an adjustable step with the standard of a stilt is not new, irrespective of its construction and operation, and my invention is therefore limited to the peculiar construction, application, and operation of the parts, as hereinafter described and shown in the drawing.

In the said drawing, A denotes the standard, which may be made of wood or any other suitable material. B is a metallic step, which extends from a rectangular or other propershaped sleeve, C, that embraces the standard, and is 'so applied thereto as to be movable thereon. D D are braces or ribs, extending underneath the step, and serve not only to support it, but are so arranged as to form a chamber to receive a cam, E, which is supported upon a fulcrum screw or pin, a, extending through the lower part of the braces, as

being clearly shown in the latter gure. Thel working-face of the cam is serrated transversely, and, when in operation, impinges against the contiguous face of the standard, the weight of the foot upon the step causing the teeth of the cam to enter the wood and maintain the step rmly in position.

The step, sleeve, and supporting arms or braces are cast in a single piece of metal, the sleeve having an internal form corresponding with the shape of the standard which it embraces, and so fitting thereon as to be capable of being slid up and down thereon.

By my improved construction of the stilt, viz., with the step, sleeve, and braces, formed or cast in one piece, as described, and the cani formed and applied thereto, as set forth, not only can the step be readily applied to its standard, but be readily moved and minutely adjusted at any desirable height thereon, as circumstances may require.

Having described my invention, what I claim is as follows:

As an improved article of manufacture the above-described stilt, consisting of the standard A, step B, sleeve C, braces D D, and cam E, the whole being formed, arranged, and operating together, in manner as shown and described.

GEORGE J. STEVENS.
