Specification of Letters Patent.

Application fried March 2e, i920.' serial` No. 369,719.

invention-are to facilitate mountinga shade on a window orif necessary, a double shade, in which latter case, the shades are operated in opposite directions `and overlap each other, thereby excluding all `light inthe spacebetween the rollers of the `different shades, to simplify the form of the bracket and keep both shades as near as possible to the window, and generally to` adapt it to betterlperform the functions required `of it With the above and other objects in view, the invention consists essentially of the improved construction particularly described and set forth in the following specification and accompanying drawings `forming part lof thelsame. i

In the drawings: Y.

Figure 1 is a perspective view of a window` frame showing the improved bracket mounted thereon, having double shades which are operable in opposite directions, and with the space between the rollers of the shades covered.

F ig. 2 is a side elevation of the same.

Fig. 3 is a side elevation of one of my brackets attached to the inner face of a window frame. n

Fig. 4 is an enlarged side elevation of the bracket shown in Fig. 3. i

Fig. 5 is a fragmentary perspective view `of a portion of the window frame showing a single roller bracket in position thereon.

Fig. 6 is an enlarged side elevation of the single bracket shown in Fig. 5.

Fig. 7 is a front elevation of the locking pulley used on the window frame.

Like characters of reference refer to like parts in the several figures.

Referring to the drawings; A represents a window frame of any usual construction y on which a double roller shade is to be mounted.

To facilitate positioning this double roller shade, I provide a bracket l1() which may be secured to the frame of` the `window `by screws or the like, which bracket consists of Patented Mar. 22, 1921.

a` flat plate having a flange 11 at right angles thereto, through 4which screws or` thc like pass to` secure the bracketin position.

Another bracket 9 is used having orifices 8 in which are j ournaled the pintles of the j shade roller. j

The platelO is provided at the upper end with an angularlydisposed opening or slot 12 having a constricted opening 13, the wall of the opening dvergingand terminating in a verticallydisposed wall 14 and horizontally disposed wall 15.` j I Adjacentto the lower `end of the plate 10, a horizontally-disposed` slot 16 is` rovided with a pin 17 bridgingl the front o the slot 16` for an object which will bemade clear hereafter. i j

A bracket` 9 is used: with one of myv improved brackets .10, the bracket 9 receiving and journaling the pintles of the shade rollj ers, :and the'biacket 10 accommodates the springprojectionsof the` rollers.

The roller 18 has its spring controlled projection engaging. with the upper slot 12, while the llower roller 19 has its springcon `tiolled projection engaging `withfthe horizontally-disposed slot 16 and the pin 17 prevents the lower roller becoming displaced.

When the lower roller 19 is in engagement with the horizontallydisposed slot 16, then the dogs which are common to such rollers hang in a neutral position and will not en gage` the spring controlled projection and render the same inoperative, so that it will be clear that the shade 2() mounted on the lower roller will always be in tension, and will not belly or flap when being lowered. It will be seen that the horizontal position of the slot 16 causes the slot to be at substantial right angles to the plane of the shade 23, in which position the dogs on the shade roller will hang in neutral position, leaving the roller free to turn without engage-,ment of the dogs in the spring controlled projection.

The shade 20 on the lower roller 19 eX- tends upwardly, and a flexible member 21 is.` attached to the same and passes over a .guide and stop pulley 22, which is shown The shade 23 of the roller 18 extends downwardly behind the roller 19 and the dogs of the roller 18 function in the ordinary manner as with an ordinary shade.

It is not thought necessary to describe the rollers as they do not form part of the present invention, but are only utilized with the particular form of bracket, which forms the subject matter of the present invention.

s In some cases a 'single shade only is used, which is operated upwardly from the bottom of the window, and in this case a single bracket 24 is secured to the frame of the Window. y

This bracket is provided with a horizontally-disposed slot 25 to receive the spring projection of the roller. Y

In this (position, the dogs on the roller` will be held in neutral position, and the shade carried by the roller will therefore at Vall times be in tension. l

When the double form of bracket is used, the shade rollers are mounted thereon as yillustrated, in Figs. 1l and 2, then the space betweenthe rollers is closed by a double shade namely 23, and 20, soV that lightcannot enter through this space. Y

The shade 20'will be actuated by a flexible member 21 and as the dogs of the roller 19 fare ina neutral position, then the shade is Y always tensioned during a winding or lower- 35 f ing operation. Y VDuringY the lowering operation, the shade .cannot belly or sag but will be rolled on its roller 19.v Y i When a single shade'is used it would be operated upwardly and then the dogs on the roller will'be in neutral position and the shade on the roller will be in tension, and when the shade is being lowered it will wind around from the roller and will not sag.

In using shades of this description, it will be clear that in Ventilating a room by opening the top of the window, the shade 20 may be lowered so that it will not Hap about with the wind; it will not extend above the open portion; the same thing= applies to shades used in the manner shown in Fig. 5.

From the above description it will be seen that I have invented a window roller bracket which can be advantageously utilized in mounting shades on a window, and which permits of double shades being used without any light entering between the rollers.

The shade rollers and stop pulley have not been described in detail because they do not form part of the present invention, and the brackets 10 only constitute the present invention.

As many changes could be made in the above construction and many widely different embodiments of my invention within the scope of the claim, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying 4specification and drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is:

A shade roller bracket, having a slot therein extending substantially at right angles to the plane of the shade, whereby when the end of the shade roller is engaged with the brackets, the dogs on the shade roller will remain in neutral position.-

In witness whereof I have hereunto set my hand.
