T. J. MOORE WINDOW SHADE Filed Aug. 5 3.92.1 2 Sheets-Sheet l Patented Aug. 5, 1924.

THOMAS JEFFERSON MOORE, OF LONGVEW, TEXAS.

WINDOW SHADE.

Application filed August 5, 1921.

To all whom t may concern.'

Be it known that I, THoMAs J. Moons, a citizen of the United States, and a resident of Longview, in the county of Gregg and State of Texas, have inventedcertain new and useful improvements in Window Shades, of which the following is a specification: i

The present invention relates in 4general to window shades, and more particularly to an improved window shade adjuster.

The object of the invention is to provide .device of this character which permits of the ready and easy adjustment 'of the window shade as a Vwhole and obviates the necessity of frequent `adjustments of the shade on its roller thereby relieving the shade of wear and endowing it with longer life, which suspends the shade so that yit hangs freely and correctly while constraining it from partaking of excessive movement under the influence of the wind, which is noiseless in operation, and which is of extremely simple and durable construction, reliable in operation and easy and inexpensive to manufacture.

Other objects and advantages of the invention reside in certain novel features of construction, combination and arrangement of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming part of this specification, and in which:

Figure 1 is a perspective view, illustrating an embodiment of the invention;

Figure 2 is a detail perspective view of the shade hanger utilized with both embodiments of the invention;

Figure 3 is a perspective view;

Figure 4 is a fragmentary view in perspective, illustrating in detail the eyes of the frame;

Figure 5 is a fragmentary detail View in side elevation, illustrating the suspension;

Figures 6 and 7 are fragmentary end views illustrating the construction of the brackets for the shade roller; and

Figure 8 is a view in elevation of a slightly modified form.

Referring tothe drawings wherein for the sake of illustration are shown the preferred embodiments of the invention, and more especially to Figures 1 to 5, the numeral 10 designates a frame constructed cfa single piece of resilient wire or from a light Serial No. 490,010.

resilient rod and including a cross bar 11 secured by fastening means 12 to the window frame. At the ends of the cross bar the `rod or wire is bent to form outwardly ex- Vbeyond the eyes let the wire or rod is extended vertically downwardly in parallel spaced relation to the window frame to provide slides or guides 15. The lower ends of the wire or rod are offset or inclined inwardly and are provided at their extremities with sockets 16 which lie flatragainst the window and cooperate with fastening means 17 to secure the lower ends of the frame in position.

A slide hanger designated generally at 20 is mounted on the frame 10 and is constructed of a single piece of resilient wire or light resilient rod which includes a cross bar 21 extending across the window and between the guides 15, angle arms 22 formed at the ends of the cross bar and embracing the guides and depending bracket 23 carried by the angular arms 22 and integral therewith. The angular arms each include a portion 22EL extending at right angles to the cross bar 21 and a portion 22b extending parallel to the cross bar.

A window shade 25 of conventional or any desired construction is carried by the slide hanger and includes a squared stud 2G at.. one end of the shade roller and received on a squared seat 23?- formed on one of the brackets l23 and a round stud 27 at the other end of the shade roller operating in a round seal or bearing 23b formed on the other bracket 23 asshown in Figures 6 and 7.

Flexible elements, such as cords 30, are provided for controlling the slide hanger. Both cords are extended through one of the eyes 14 and one of the cords is then extended downwardly for connection with the adjacent bracket 23 and the other cord is then extended across to and through the other eye 111 and is then extended downwardly for connection with the other bracket 23. The free ends of both cords hang by the window frame within convenient reach of the operator and may be tied or connected with the keeper 31 for securing the slide hanger in adjusted position.

@ne of the important features of the present invention resides in the connection of the cords to the slide hanger. As shown in Figure 5 the cord 30 extends down behind the cross bar 21 of the slide hanger that is between the cross bar and the window frame and then under the cross bar and over to the bracket 23 to which it is connected, as at 35. In this manner the cross bar 2l is ful-l crumed on the cord, as at 36, and in view of the connection the weight of the shade produces a moment of force which acts to swing the slide hanger to position to cause the curtain to hang vertically and correctly with the pawls 2bL of the shade roller in position to fall byV gravity into their seats. It is to be understood in this connection that a serious disadvantage inherent in all types of adjustable window shades heretofore proposed has been that the weight of the curtain is eective to cant the shade roller and its hanger thus throwing the pawls into such position as to render them inoperative and tending to bind the shade hangersv in their guides.

In Figure 8 there is shown an embodiment of the invention in all respects identical with the foregoing embodiment except that it is adapted for use Where the window shade is wider than the window frame without the necessity of blocking up. In this embodiment the frame is designated at 40, the cross bar 4l being slightly wider than the window frame so that the slide rods 42 extend along the outside ofthe window frame as shown in the'drawings, the lower ends of the guide or slide rod being bent inwardly as at 48, and secured to the frame as at 44. 'Ihe slide hanger is designated at 45 and supports the window shade in the same manner as the slide lhanger above described and differs only in that it is made slightly larger to correspond to the frame. The slide hanger is suspended and controlled as in the other form.

In Figure 3 the frameis shown bent or folded up so as to be susceptible of being compactly packaged or crated for shipment.

I claim:
