PU LLEY ATTACH NI ENT.

SPECIFICATION forming' part of Letters Patent No. 234,585, dated November 16, 1880.

Application filed September 30, 1880.

To all whom it may concern:

Be it known that I, FERDINAND A. Krr'rELL, of Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented a certain new and useful Improvement in Pulley Attachmcnts; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings.

Figure l is a side elevation, partly in section. Fig. 2 is a rear edge view. Fig. 3 is a plan View; Fig. 4, a modification.

This invention relates to devices for attachment to pulleys or sheaves for the purpose of permitting` a play of the pulley without risk of fouling the line by slipping over the sheaverini, and at the same time preserve the line in undisturbed relation to exterior objects.

The invention consists in hanging the pulley or sheave in an L-shaped bracket, which is swiveled or pivoted to a support in such manner that the bracket and its pulley will have free circular motion around one periphery of the sheave as an axis; further, in the constructie and combination of parts, substantiall y as hereinafter described and claimed.

A designates a girder, beam, or other elevation upon which it is desired to attach a pulley. Beam A is in this case bored through for the passage of the rope a. On top of the beam A, I secure the plate B, having the annular projecting boss b, through which rope a passes. An L -shaped bracket, C, carries the pulley, and at its other extremity is provided with the eye orthimble c, which fits down over projection b as a pivot. The center of the eye c is exactlyin line withthe center of the rope and the periphery of the pulley. As thepulley turns (No model.)

upon the projection b, and as the periphery of the pulley is immediately upon the axial line, it follows that no matter how the pulley and bracket may sway around on the axis the rope will always run true, and no tendency arises for it to slip over the rim of the pulley.

The device is especially adapted to lead a rope to a winding drum or reel where the winding causes the rope to travel laterally with reference to the pulley, the lateral movement being compensated by the swing permitted the bracket.

Fig. 4 shows a modication of the construction. Plate B rises upwardly and the bracket swings on a pin, i, passing through it and the transverse portions m of frame B. The latter is high enough to bring the pulley to the proper point.

Instead of leading the rope through the beam A the device maybe flanged for attachment to the face of the beam 0r a wall, but the described construction is preferred, as it is applicable t0 many special situations-for instance, elevators, sash-cords, to many varieties of special tackle, and to windlasses of various kinds.

I claim as my inventiony The combination of plate or frame B, having annular projection b, L-shaped bracket O, having eye c, and pulley or sheave D, having its periphery coincident with the axis of eye c, substantially as described.

In testimony whereof I have hereto set my hand.

FERDINAND A. KITTELL.
