Description
UNITED STATES PATENT OFFICE.
AMOS S. BLAKE, OF WATERBURY, CGNNECTICUT.
IM PROVEM ENT IN PU LLEYS.
Specification forming part of Letters Patent No. 59,172, dated October 30, 1866.
scription thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure lis a front elevation of my invention. Fig. 2 is a transverse vertical section taken on t-lie line x, Fig. l.
Similar letters of reference indicate like parts.
This invention is adapted particularly for closing doors, gates, Src., where weights are employed.
My invention consists in a swivel sheavefraine, having its bearings in arms arranged at an angle with the bed-plate, by which the device is attached to the post of the gate or casing ofthe door, or elsewhere, in such manner that the rope which passes over the sheave will not come in contact with the said plate, whether theplate be aflixed in a horizontal or vertical position, thereby giving to the sheaveframe the capacity of adjusting itselt' to the varying direction or draw of the cord.
A designates the bed-plate, and this is provided with a suitable number' of perforations, for attaching it by nails or screws to any surface on which it is to be secured. B B are two arms, which extend out from the plate A in a direction to bring their extreme ends beyond the inner edge of the bed-plate A. Into these arms is journaled the sheave-frame G in such manner as tov allow it a rotary motion. The sheave or roller D is pivoted between the two cheeks of the sheave-fraine in any suitable way.
I have constructed the sides or cheeks of the frame with ears a a, project-ing outward from each in opposite directions, as shown clearly in Fig. 1. These ears serve as guides for the. rope to keep it from tlying out of the groove in the periphery of the sheave, as is evident.
vIt will be noticed that by setting this roller in a swivel-frame it is allowed every motion necessary to, allow it to vary according to the direction of the draw of the rope passing over it, and hence it operates inueh more perfectly than were it hung in rigid bearings, and that.
by journaling the swivel-frame in arms B B, whose ends project out beyond the bedfplate A, when the bed-plate is seeuredin a horizontal position, no interference ot' the rope with the bed-plate can occur.
What I claim as new, and desire to secure Witnesses:
JOHN ONEAL, Jr., L. SANFORD DAVIEs.
