NITED STATES THOMAS J. SPENCER, OF FALLS CITY, NEBRASKA;-

WINDOW-SHADE FIXTURE.

SPECIFICATION forming part of Letters Patent No. 723,748, dated March'24, 1903. Application filed May 121 1902. Serial No. 106i983. (No model.)

To all whom itmcry concern: I

Be it known that I, THOMAS J. SPENCER, a citizen of the United States, residing at Falls City, in the county of Richardson and State of Nebraska, have invented certain new and useful Improvements in Window-Shade Fixtures, of which the following is a specification. 7

My invention relates to improvements in windowshade fixtures; and the object of my invention is the provision of a simple, inexpensive, and practical means for adjusting the shade with reference to the window to admit the light at the upper or lower'portion of the window, as desired.

To attain the desired object, my invention consists of a window-shade fixture embodying novel features of construction and combination of herein. 7

Figure 1 represents a front elevation of a window -frame provided with my fixture. Fig. 2 represents a similar view with parts of my fixture in section. Fig. 3 represents a side view, and Figs. 4 and 5 represent detail views, of parts of my fixture. Fig. 6 is an enlarged detail in side elevation.

In the drawings the letter A designates the window-frame to which my fixture is applied, and to one of the upper corners of the frame is attached the post, which carries the easing and drum B, in which isjournaled the single grooved guide-wheel B and formed on the casing, is the tubular chain-guide B To the opposite corner of the frame is secured the post 0, carrying the drum or casing 0,

parts, substantially as disclosed in which is mounted the pair of grooved guide-wheels O and thiscasingis alsoformed with a tubular chain-guide C The shade-supporting bar-D carries the depending shade-brackets E, which support the shade F, and adjacent to the shade-brackets are secured the sleeves G, which are each formed with a lug H, to which lugs are connected the cord or chain J, which passes through the guide B over the rollers or wheels B and C and has itslower end connected to the inner end of the link K, and to the other lug is connected the cord or chain L, which passes through the guide 0 over one of the wheels 0 and has its lower end connected to the other end of the link K. From this construction it will be seen that the shade is supported upon the bar and that it can'be rolled and unrolled with ease and that by raising or lowering the chains the shade can be adjusted with referenceto the window to admit the light above or below, and to hold the shade at'any adjustment I provide a novel mechanism. This consists of the post M, secured to one side of the frame at the lower portion, upon which post ismounted the drum N, in which revolves the shaftO, having connected therewith the tape P, which is adapted to bewound and unwound and which passes out of the drum and is connected at the upper end to the link at Q. To theouter end of the shaft 0 is secured the arm R, which is formed with the sleeve S, in which is fitted the horizontal bolt T, having a handleU and adapted to engage any one of the openings Vin the drum, and the bolt is forced into any of the openings'V by means of the spring W, forming a spring-bolt. It will thus be seen that the bolt can be released and the tape wound or unwound upon the shaft and the shade adjusted, and when at the desired place the springbolt will engage one of the openings and hold the shade at the proper place. I also provide the chain X, which is connected to the link K at one end and has the other end connected to the keeper Y, and the chain serves to draw the shade up and down, and the keeper holds the chain by the engagement of the chain in the keeper. I

The chain X is used for ordinary lightweight shades, and the tape with operating mechanism is used for heavy shades.

It willbe seenthat I providea fixture of ornamental appearancewhich can be made at a comparatively low price and which is efficient and practical for the purpose intended.

I claim 1. In a window-shade fixture,the combina"- tion of the shade, the supporting-bar,'the operating connections leading from the bar, the single and double guide-wheels for :the connections, the link connected to the lower ends of the conuections,the chain connected to the link and the keeper for holding the chain at the proper adjustment, the drum secured to the casing, the shaft in said drum, the tape adapted to be wound upon the drum, the

ICO

hook on the end of the tape to be connected to the chain, the crank on the shaft for winding the tape, and the spring-bolt carried by the crank to engage the drum to hold the tape rigid when desired.

2. In a window-shade fixture, the combination of the bar, the shade-brackets depending therefrom, the shade mounted in the brackets, the sleeves on the bar having a lug, the cords or chains connected to said lugs, the guides to receive the chains and lug, the wheels for guiding the chains, the link connected to the lower ends of the chains, the operating-chain, and the keeper for holding the chain at the desired adjustment,the drum secured to the casing, the shaft in said drum, the tape adapted to be wound upon the drum, the hook on the end of the tape to be connected to the chain, the crank on the shaft for winding the tape, and the spring-bolt carried by the crank to engage the drum to hold the taperigid when desired.

In testimony whereof I affix my signature in presence of two witnesses.
