FIXTURE.
SPECIFICATION forming part of Letters Patent No. 356,369, dated January 18, 1887.
Application led July 19, 1886.
To all whom it may concern:
Be it known that I, OLIVER F. MITCHELL, a citizen of the United States, residing at Merrill, in the county of Lincoln and State of IVisconsin, have invented new and useful Improvements in OurtanFiXtures, of which the following is a specification.
This invention has for/its object to provide novel, simple, and eflicient means for sup- Io porting and adjusting a window shade or curtain to any desired part of a window, for t-he purpose of excluding the rays of the sun from any part of the window, admitting light and ventilation either at the upper or the lower end of the window, or at both ends, without liability of injury to the curtain from wind.
The object of myinvention I accomplish by the construction and combination of devices hereinafter described and claimed, reference 2o being had to the accompanying drawings,illus trating my invention, in which- Figure 1 is a front elevation of a windowframe having a shade or curtain roller supported and adjustable according to my invention; Fig. 2, an elevation, looking at one end of the shade-roller; Fig. 3, asimilar view, looking at the opposite end of the shaderoller; Fig. 4, a detail perspective view of the lpivoted swinging catch and its bearings.
3o In said drawings, ,the numeral 1 indicates a shaft journaled at its ends in brackets or bearings 2 at the top of the window-frame, and carrying two attached sprocket-wheels, 3, which, as here shown, are located, respect- 3 5 ively, between the side arms of the brackets or bearings.v This shaft may be square, lround, or of other shape in cross-section, and the brackets or bearings therefor may be of any suitable construction. An endless chain, 4.,
4o passes around and engages each one of the sprocket-wheels, and such chains pass around pulleys 5, journaled in bearings 6 at or adjacent to the bottom of the window-frame, at the opposite sides thereof, so that a person drawing on one chain correspondingly moves the other chain through the medium of the sprocket-wheels and shaft.
In place of one or more of the links comprising each chain, I introduce aplate, 7, hav- Serial No. 208,443. (No model.)
ing an orifice, 8, larger at the top than at the bottom, such plates forming the bearings for the journals 9 of the shade-roller 10. I prefer to employ a spring shade-roller of any well-known type, and in order to retain the journals thereof in their bearings and prevent the chains from spreading in a direction away from each other, I provide the ends of To adjust the shade-roller to the desired positio'n,one of the chains is grasped and drawn in the proper direction, when the other chain will be moved in unison therewith by the sprocket-wheels and shafts, as before stated, and after the roller is brought to the proper position the shade or curtain can be raised or lowered by the rotation of'the'roller. v
To lock the chains, and thereby hold the shade-roller in its adjusted position, I provide a locking-catch, consisting, as here shown, of a vertical rod, 12, mounted in bearings 13, and provided at one end with a handle, 14, and at the other end with a lateral hook, 15, in such manner that by axially turning the rod the hooked end thereof engages or disengages one of the chain-links.
To prevent lateral displacement of the chains on the sprocket-Wheels, it may be found desirable to provide the latter with side anges to embrace the chains; but I do not regard the same as essential.
I am aware that a single endless chain has been employed to wind and unwind the shade from a shade-roller journaledl in brackets at the top of a window-frame; and I am also aware that a shade-roller has been mounted at its ends in plates secured to two endless cords 2. rIhe combination, in a c111tai11xture, of a shaft having a sprocket-wheel at each end, 15 an endless chain engaging each Wheel, a shade roller having its ends supported by the chain- ]inks, and a rotating rod having a hook for engaging one of the chain-links, substantially as described.
In testimony whereof I affix my'signature in presence of two Witnesses. v
OLIVER F. MITCHELL.
