UNITED STATES PATENT OEEICE PETER GENDRON, OF TOLEDO, OHIO, ASSIGNOR TO THE GENDRON IRON WHEEL COMPANY, OF SAME PLACE.

VELOClPEDE-TREADLE.

SPECIFICATION forming part of Letters Patent No. 298,079, dated May 6, 1884.

Application tiled November 3, 1883. (No model.)

To @ZZ whom it may concern,.-

Be it known that I, PETER GENDRON, of

Toledo, in the county of Lucas and State of Ohio, have invented new and useful Improvements in Velocipede Treadles and Oranks; and I do hereby declare that the. following is a full, clear, and exact description thereof, ref` erence being had to the accompanying drawings, which form a part ,of this specification.

This invention relates to certain new and useful improvements in the construction ot treadles and cranks for Velocipedes and tricycles, by means of which a durable and economical device is obtained.

The invention consists in the peculiar construction of the parts and their combination, as more fully hereinafter described.

Figure l is an elevation, in perspective and partially in section, of lmy improved crankl and treadle, showing the construction when the parts aresall made of metal. Vertical section showing the construction where the crank is madev of metal and the treadle itself of wood.

In the accompanying drawings, which form a part of this specification, A represents the crank, provided with the internally-squaredY socket a, to engage with the end', of the axle. This crank is cast solid with the thimble B, theinterior bore of which is preferably slightly conical in shape, although .not necessarily so, and preferably cast upon a chill. Y

C represents the treadle, which is composed of the head b, the two outside footbearings c, stops d, to preventthe foot from slipping oft the ends of the footfbearings, and a pintle, D,

Fig. 2 is aV the ylatter being of the same size and shape as the interior bore of the thimble B, into which the pintle is inserted when the parts are all made of metal, and secured by means of a nut, e; or, in a cheaper Variety of Vehicles, the end ofthe pintle may be riveted. Stops f perform the double function of arresting the thrust of the pintle into the thimble too great a distance, and also connecting the foot-bearings c with such pintle, to give greater stiffness to the treadle. Vhen a treadle, E, is employed, it isI bored through the center with bores of diferent diameters, as shown in Fig. 2, the larger bore engaging with the outside of the thimble and the smaller bore of the diameter of the pintle, which is inserted through such treadle and the thimble, and the parts se cured together by means of the nut e or riveting, the opposite end of such pintle being provided with the head g, to allow the parts to be thus secured together. What I claim as my invention is-" 1. A velocipede treadle and crank, consisting of a crank cast with a thimble, and apintle. sleevedwithin said thimble andsupporting the treadlesubstantially as described.

2. In combination with a crank cast with a thimble, a treadle composed of the foot-bearings c, stops d f, head b, and pintle D, the parts being constructed, arranged, and oper-` ating substantially as specified.

PETER GENDRON.
