Description

- fij@ N,PETERS, FHOYQLITNOGRAPHER. WASHINGTON. D CA UNITED STATES JOHN B. TARE, OF CHICAGO, ILLINOIS.

IIViPROVED CURTAIN-FIXTURE.

Speciti cation forming part of Letters Patent No. 53,703, dated April 3, 1866.

To all whom it' may concern:

Beit known that I, JOHN B. TARR, of Chicago, in the county of Cook and State ot Illinois, have invented a new and Improved Shade- Fixtnre and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompa- I n ying drawings, making a part ot this specification, in which- Figure lis a front elevation of a windowi'raine having my improved shadc-xture applied to it, the shade being represented as drawn up. Fig. 2 is a similar view, showing the shade when it is drawnV down. Figs. 3 and 4 are vertical sections, showing the shade in two positions.

Similar letters ot reference indicate correspondin g parts in the several gures.

The object of my invention is to provide for` raising and lowering a window-shade where the roller upon which the shade is rolled is located at or near the bottom ot' the windowi'ralne for the purpose ot' obtaining the light from above instead of from below the shade, employing for said purpose a single cord and a spring tension device, as will be hereinafter explained.

To enable others skilled in the art to understand my invention, I will describe its construction and operation.

In the accompanyingdrawings, Arepresents a window-frame; B, a roller upon which the curtain or shade a is rolled.

c c are the end bearings for the roller B, which may be secured either to the windowsill, as shown, or to the sides of the windowframe.

A cord, b, is passed beneath the roller B and over a pulley, c', at the upper part of the window-frame, and the ends of this cord are secured to the curtain-strip d', the cord being drawn tight when the curtain is unrolled, as in Figs. 1 and 3.

The pulley c is arranged directly over the point where the two ends of the cord b are secured to the curtain or shade strip, which point is in the middle of the length of this strip, as shown in the drawings. The pulley c is pivoted between the ends of a forked pin, g, which pin is acted upon by a spring, c, that is held in place by the bearing-plate h. The object ot' the spring e is to keep the cord b under proper tension when the curtain or shade a is unwound from its roller, and to allow of the pulley descendingmore or less, according to the increased diameter of the roller when the shade et is wound upon it, as shown in Figs. 2 and 4. By keeping the cord b tight the curtain or shade a, which is secured to said cord, will also be kept tight and in its place.

The spring-pulley c may be applied to a shorter stem than that shown in the drawings, and this stem and its spring may be inclosed within a neat box, which will present a handsome appearance on the window.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

rlhe arrangement of the lower roller, B, endless cord b b, curtain a a, attached to the endless cord, and the tension-roller c', substantially as set forth.

J. B. TARE.
