PULLEY.

SPECIFICATION forming part of Letters Patent No. 415,948, dated November 26, 1889.

Application filed February 23, 1889- Serial No. 300 ,929- (No model.)

To all whom it may concern.-

Be it known that I, JOHN A. J. SHULTZ, of St. Louis,-Missouri, have made a new and use ful Improvement in Pulleys, of which the following is a full, clear, and exact description.

The improvement relates to the facing of the pulley. The facing consists usually of leather; but I desire not to be restricted thereto.

The improvement consists more especially in the mode of attaching the facing to the pulley. The pulley, saving as it is supplemented or modified by the improvement under consideration, is of any of the customary forms. The facing is made wider than the pulley-face and its edges are carried over.

' the edges of the pulley-face and then turned inward within the pulley-rim and secured to each other, substantially as is hereinafter set forth and claimed, aided by the annexed drawings, making part of this specification, in which- Figure l is a view in perspective of a pulley having theimprovement; Fig. 2, a cross section of the pulley-rim having the facing attached, and Fig. 3 a view in perspective of one of the lugs used toattach' the facing to the pulley.

The figures are respectively upon different scales.

The same letters of reference denote the same parts.

A, Fig. 1, represents a pulley to which the improvement is applicable.

B represents the facing. It is attached as follows: The facing is made wider than the pulley-rim a and the side edges 1) b are respectively turned over the side edges a a of the pulley-rim and then extended toward each other Within the pulley-rim, and the facing is secured by means of fastenings which serve to unite the opposing facing edges, and as the most desirable means to that end I employ the lugs O, Figs. 1, 2, and 3, and bolts D, Figs. 1 and 2, each facing edge being provided with a series of lugs, and the bolts being used to connect the lugs of one of the facing edges with the corresponding lugs of the opposite facing edge. The preferable form of lug is that shown-namely, a mallea 5o ble piece of metal at its end a suitably shaped to be applied to the facing edge and to come between the facing edge and the pulley-rim, and having points or other means for securing the lug to the facing edge. The

sented in Fig. 3, and after the points are passed through the facing edge they are clinched thereupon, substantially as is represented in Figs. 1 and 2. At its opposite end the lug is provided with or is shaped to form a flan e c which is erforated to receive the 6: b 7 .1

bolt D, as shown in Figs. 1 and 2, theboltbeing held in the flanges c c of the opposing lugs, and the facing is finally secured by screwing the nut (1 onto the bolt until the facing is prop-v erly tightened upon the pulley-rim, and this is an additional feature of the improvement that by making the nut to be turned upon the bolt, as shown and described, the ties D may from time to time be shortened as the facing stretches, and the tightness of the facing thereby maintained. In the direction of its length the facing may be secured in any wellunderstood manner-that is, the facing end (not shown in the drawings) may be suitably united or in any manner suitably held in place upon the pulley-rim.

I claim A pulley having a facing which is wider than its rim and having its side edges turned over the side edges of said rim and extended toward each other and united by means of lugs and tie-bolts, substantially as described.

lVitness my hand this "18th day of February, 1889.

JOHN A. SIIULTZ.
