WHEEL FO R MOTOR-CYCLES.

. SPECIFICATION forming part Of Letters Patent NO. 718,094, dated January13, 1903.

Application filed October 3, 1902. Serial No. 125,767. (No model.)

T0 at whom it may-concern:

Be it known that I, ADOLPHE CLEMENT, a citizen of the Republic of France, residing in Levallois-Perret, Seine, France, have invented certain new and useful Improvements in Wheels for Motor-Cycles, of which the following is a specification.

This invention relates to a means of mounting pulleys upon the driving-wheels of motorcycles.

I have devised an extremely simple method of mounting upon the spokes of the drivingwheel of motor-cycles the pulley,in the groove of which passes the cord driven by the pulley of the motor. Although this manner of mounting it is so simple, it insures great strength of the assemblage between the wheel and the pulley-rim.

The invention will be readily and clearly understood by reference to the accompanying drawings, in which Figure 1 is a vertical cross-section through abicycle-wheel with driving-pulley attached. Fig. 2 is a side elevation of the wheel upon that side on which the pulley is fixed. Fig. 3 shows, full size, the assemblage of the policy with the wheel-rim and with the spokes in cross-section. Fig. 4 shows, full size in side elevation, a detail of this mounting, the view being taken upon the side opposite to the pulley. Fig. 5 -is a section on the line M N of Fig. 3.

The pulleyis constituted by a metal rim A, of V-shaped cross-section. It is fitted to the rim upon the one hand by means of small tension-spokes a, which bear upon the wheel-rim B, and on the other hand by means of stays p, which are riveted upon the pulley-rim and which bear upon the wheel-spokes r.

The tension-spokes a are curved at 1) upon the side of the pulley-rim A, and the extremity which enters the V portion of the pulley is riveted in such a manner as to firmly connect the pulley-rim and the spokes a. The opposite extremity of this tension-spoke a is connected to the wheel-rim B by means of a screw-nut c in the same manner as the ordinary spokes of bicycles.

The stays p, which, as above stated, are riveted upon the pulley-rim, are of the form of small horizontal pillars, the head of which is riable position is imparted to the pulley-rim with respect to the bicycle-wheel.

It will be understood that the tension exerted upon the spokes a produces a horizontal component, which tends to cause the stays p to bear strongly against the wheel-spokes,

and thus impart great rigidity to the whole.

In order to obtain an efficient mounting of the pulley-rim upon the wheel and to insure that this pulley maybe perfectly central with respect to the wheel, only a few diametrically opposite spokes a are first of allinserted-say four, for example. When these have been Well adjusted, the mounting is completed by inserting the intermediate tension-spokes.

I claim as my invention- 1. A wheel for a motor-cycle comprising a hub, rim and spokes, combined witha pulleyrim mounted upon it,tension-spokes obliquely connecting the pulley-rim with the wheel-rim, and stays interposed between the pulley-rim and the wheel-spokes.

'2. A wheel for a motor-cycle comprising a hub, rim and spokes, combined with a pulleyrim mounted upon it,tension-spokes obliquely connecting the pulley-rimzwith the wheel-rim, and stays interposed between the pulley-rim and the wheel-spokes, united at one end to the pulley-rim and having notches at their other ends engaging the wheel-spokes.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

EDWARD P. MAGLEAN, GABRIEL BELLIARD.
