SPLIT PU LLEY.

SPECIFICATION forming part of Letters Patent No. 390,102, dated September 25, 1888.

Application tiled February 3, 1888. Serial No. 262,897. (No model.)

To all whom it may concern.-

Be it known that I, ADOLPH H. \VAGNER, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Split Pulleys; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to split pulleys; and it consists in certain peculiarities of construction and combination otparts, to be hereinafter described with reference to the accompanying drawings, and subsequently claimed.

In the drawings, Figure 1 represents a side elevation of a pulley constructed according to my invention and partly broken away on line 1 1, Fig. 2; Fig. 2, a face view of the pulley, partly in section, on line 2 2, Fig. l, and Fig. 3a transverse section on line 3 3, Fig. 1. Figs. 4 and 5 are detail views of the meeting edges of the pulley-sections.

The rim of the pulley is made in the usual manner and then cut in two to form sections A B, the sides of said rim being finished with a bead, G, that hides the cuts and increases the width of face. Half-round recesses E are cut in the meeting ends of the rim sections, and when these sections are together said recesses form circular openings for dowelpins F, the latter being shown as permanently secured by transverse pins or nails P, as shown in Figs. 1, 2, and 5, in the recesses of the rim section B.

\Vhile I have shown thehalf-round recesses E and circular pins F, it is obvious that said recesses and pins may be angular,if found more desirable, the purpose of the pins being to pre vent lateral displacement of the sections A B that form the rim of the pulley.

Mortised in each rim-section of the pulley are the ends ofa transversebracepiece, G, said rim-section and brace-piece being keyed together by dowel-pins II that are shown as circular, butwhich may be of any other desirable form.

Passed through the bracepicces of the opposing pulley-sections are rods I, and on the ends of these rods are arranged clamping-nuts J.

Each of the brace-pieces G is centrally recessed to engage a square hub, K, the latter being preferably made in two sections for the sake of convenience, and held in place by the pressure of said brace-pieces. The hub K being detachable from the pulley, any-sized shaft can be accommodated without the employment of bushings, as it is only necessary to know the diameter of said shaft in order to furnish a hub having a correspoudingly-proportioned here, it being intended that all hubs shall be of a standard size as regards outside measurement, and differ only as to the diameter of bore.

By the construction above described I pro vide a simple, easily constructed, and durable split pulley that has no liability to get out of shape or run loose on the shaft to which it may be connected.

I am aware that heretofore split pulleys have been made with removable hub-sections interposed between the arms thereof.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. A split pulley having the meetingedgcs of its sections recessed, and dowel-pins fitted into the openings formed by the recesses and secured by transverse pins passing through said dowel-pins and into one of said sections, substantially as set forth.

2. A split pulley having its rim-sections A. B recessed at their meeting ends, dowel-pins fitted into the openings formed by the recesses and seen red by transverse pi us passing through said dowel-pins and into one of said sections, the transverse brace-pieces G, mortised and doweled in the rim-sections, the hub K, detachably fitted between the brace-pieces, the rods I, and clamping-nuts J, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Visconsin, in the presence of two witnesses.

ADOLPH H. WAGNER.
