DAVID H. HARNLY, 01E AUSTIN, ILLINOIS.

ADJUSTABLE WIN DOW-SHADE.

Application filed February 2, 1912.

To all whom it may concern;

lie it known that 1, DAVID ll. HARNLY, a citizen of the United States, and resident of Austin, county of Cook, and State of illinois, have invented certain new and useful Improvements in r'idjustable lVindow- Shades, of which the following is a specification, and which are illustrated in the companying drawings, forming a part thereof.

The invention relates to window shades which are carried by vertically adjustable supports, and appertains particularly to the pulley brackets for carrying the supports, the guide rods upon which the supports run and to means for equalizing the cords or chains by which the supports are suspended; the object of the invention being to provide a cheap yet strong and serviceable bracket, simple means for securing the guide rods and an efficient equalizing device for the cords or chains.

The invention is fully scribed and is illustraed in ing drawings, in which- Figure 1 is a detail perspective elevation of a window with the shade applied thereto; Fig. 2 is a perspective of one of the brackets; Fig. 3 is a perspective of the companion bracket; Figs. 4 and 5 are blanks respectively of the two brackets; and Fig. 6 is a detail of the cord equalizing device.

The window frame is shown at 10 and the shade at 11. This shade is carried by a pair of supporting members 12, 18 here shown as in the form of plates which are suspended respectively by chains 14, 15 running on suitable rollers journaled in brackets 16, 17 which are secured to the upper ends of the stiles of the window frame; the chains 14, 15 extending down at one side of the window and being attached to a cord or chain 18 which may be engaged with a hook 19 set in the frame stile for the purpose of se curing the shade in its adjusted positions. The supporting elements 12, 13 are guided by rods 20, 21 extending vertically along the faces of the frame stiles. The suppor ing brackets 16, 17 are substantially alike except that they are made to fit opposite sides of the window frame and one 01 them carries a single roller while the other is pro vided with a pair of rollers, one of the chains, as 15, being carried across the top of the window frame.

hereinafter dethe accompany- Specification of Letters Patent.

Patented Nov. 19, 1912.

Serial No. 674,944.

The brackets 16, 17 are of sheet metal and are formed up from blanks shown in Figs. 4t and Each bracket comprises a side plate 22 or and an end plate 23, both of these plates having screw holes either or both of the plates taking a bearing against the window frame and being secured thereto by means oi screws. The sole 24 oi the bracketis formed by folding the blank along the dotted line 25 to bring it perpendicular to the wall plate 22 or The outer end of the sole plate 24 is bent downwardly on the dotted line 26. The outer end portion 27 of the side wall plate 22 is bent on the dotted line 28 to fold it under the sole slate thus bringing it parallel with the depending end portion 29 of the sole plate. The parallel lugs 27, 29 thus formed are apertured in line as shown at 80, 31 to receive the arbor of the rollers 32, 33 over which the chains 14, 15 run, these rollers being spaced apart by an annular disk 34:.

in the case of the bracket 17 the side wall plate 35 is somewhat longer than the corresponding wall plate 22 of the bracket 16, thus bringing the parallel lugs 2. 29 closer together as but a single roller 36 is employed.

The end wall plate 23 of each bracket is cut so as to permit the turning down to horizontal position of a lip 37 which is apertured as shown at 38 to receive the upper end of the rod 20 or 21. The lower ends of these rods are attached to the stiles of the window frame, as shown at 39, 40, each being bent or looped to form a screw eye.

The depending ends of the chains 1 15 are attached to an equalizing loop 41 con sisting 01 a short nictal strap, there being used for this purpose metal which is pliant, being non-elastic. The pull cord 18 is attached to the loop 41, preferably by means of a yoke, the loop passing through the yoke. It is important that the chains 14, 15 be easily adjusted as to length and that the adjustment be maintained. The use of a pliant metallic strap for forming the equal izing loop provides for this case of adjustment by merely bending the metal to form the bow for receiving the roller of the attaching yoke,as in ay be required to properly proportion the length 01'? the two chains. The metal strap, however, will retain the form given iteven though considerable more resistance may be developed by friction at one end of the shade than at the other.

lVhile ordinarily the brackets 16, 17 will be mounted with their wall plate 22 or 35 bearing against the face of the frame stile they may, if desired, be so placed that their opposite sides are adjacent the face of the stile, longer screws being used to pass through the wall plates. The apertures 38 in the lugs 37 are located midway between the sides of the brackets to permit this re-' Yersal of position without Varying the distance of the rods 20, 21 from the face of the stile frame.

I claim as my invention 1. In an adjustable window shade, the combination with a shade, supports for the shade and carrying cables, of brackets for attachment to a window casing each bracket having a sole plate, end and side wall plates, a pair of parallel lugs depending from the sole plate and a cable-carrying roller journaled between the lugs; and guide rods for engaging the supports, the upper end of each guide rod projecting loosely into an aperture in one of the brackets.

2. In an adjustable window shade, the combination with a shade, supports for the shade and carrying cables; of brackets for attachment to a window casing each bracket being formed of sheet metal folded to form a sole plate, a wall plate and a pair of parallel lugs depending from the sole plate, a cable-carrying roller journaled between the lugs of each bracket, and guide rods for engaging the supports, the upper end of each rod projecting loosely into an aperture in one of the brackets.

3. In an adjustable window shade, the combination with a shade, supports for the shade and carrying cables, of brackets for attachment to a window casing each bracket having a sole plate and a wall plate and a pair of parallel lugs depending from the sole plate, a cable-carrying roller journaled between the lugs of each bracket, and guide rods for engaging the supports, the upper end of each rod projecting loosely into an aperture in one of the brackets.

4. In an adjustable window shade, the combination with a shade, supports for the shade and carrying cables, of brackets for attachment to a window casing each bracket having a sole plate, a wall plate, a pair of parallel lugs depending from the sole plate and an apertured lip instanding from the wall plate, a cable-carrying roller journaled between the lugs of each bracket, and guide rods for engaging the supports, the upper end of each rod projecting into the aperture of the instanding lip of one of the brackets.

In an adjustable window shade, the combination with a shade, supports tor the shade and carrying cables, of brackets for attachment to a window casin each bracket having a sole plate and a wall plate and a pair of parallel lugs depending from the sole plate, a cable-carrying roller ournaled between the lugs of one of the brackets and a pair of such rollers journaled between the lugs of the other bracket, and guide rods for engaging the supports, the upper end of each rod projecting loosely into an aperture in one of the brackets.

6. In an adjustable window shade, in combination, a shade, a pair of supports for the shade, a pair of brackets adapted to be attached to the upper end of a window casing, one of such brackets carrying a single roller and the other of such brackets carrying two rollers, cables for carrying the supports and running over the rollers, the ends of the cables depending at the same side of the casing, an equalizing loop uniting the depending ends of the cables and being formed of a ribbon of pliant metal and a pull cord looped onto the equalizing loop.
