ADJUSTABLE SHADE-BRACKET.

Specification of Letters Patent.

Patented Oct. 18, 1910.

Application filed September 15, 1909. Serial N 0. 517,941.

To all whom it may concern:

Be it known that I, JAMES M. MAYS, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Adjustable Shade Brackets, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to adjustable curtain shade roller supports, and the objects of my invention are to provide positive and re liable means for adjustably holding a curtain shade roller in connection with the window frame, and to furnish a window frame with means whereby the curtain shade roller can be easily raised or lowered and held in an adjusted position.

Other objects of my invention are to pro vide a curtain shade roller support that will not sag or become displaced when adjusted, and to aiford novel means for adjusting the support to window frames of various sizes.

Further objects of my invention are to ac complish the above results by a strong and durable fixture easily applied to a window frame, and to provide a support of the above type that will be comparatively inexpensive to manufacture and highly efficient for the purposes for which it is intended.

These and such other objects as may hereinafter appear are attained by the mechanical construction shown in the drawing forming a part of this specification, wherein there is illustrated the preferred embodiments of my invention; but it must be understood that the structural elements thereof can be varied or changed, as to the size, shape and manner of assemblage without departing from the spirit or scope of the invention.

In the drawing :-Figure l is a front ele vation of a portion of a window frame equipped with my improved curtain shade roller support, Fig. 2 is a vertical sectional view of the support on the line 00-00 of Fig. 1, Fig. 3 is a longitudinal sectional view of a portion of one of the revoluble shafts of the holder, Fig. 1 is a plan of a portion of the holder, Fig. 5 is a longitudinal sectional view of a portion of a modified form of plate, Fig. 6 is a plan-of a modified form of holder, Fig. 7 is a horizontal sectional view of a modified form of rack adapted for use in connection with the holder, and Fig. 8 is a perspective view of a clip used in connection with the holder.

In the drawing 1 denotes a window frame having the inner sides thereof adjacent to the upper sash 2 provided with vertical racks 3 and J-shaped guide strips 4, said strips and said racks being secured to the frame by suitable fastening means, as screws 5.

6 denotes a plate having the upper and lower edges thereof provided with lateral oppositely extending flanges 7 and 8. The ends of the plate 6 are provided with the conventional form of brackets 9 for revolubly supporting a curtain shade roller 10. The rear side of the plate 6 is provided with brackets 11 having hook shaped vertical edges 12 adapted to engage the guide strips 1 of the window frame. Revolubly mounted in the brackets 11 are longitudinal shafts 13 having the ends thereof provided with pinions 14 adapted to mesh with the vertical racks 3. The racks, pinions and shafts are used to cause a uniform movement of the ends of the bracket. As the bracket is only moved at one side of the window-frame, there would be a liability of the structure binding on account of the interlocking guides, but through the medium of the shafts, pinions and racks, one end of the bracket will be moved just as far as the other end, thus insuring an even and uniform movement.

Attached to the flange 7 at one end of the plate 6 is a cord or cable 15 adapted to pass upwardly over a sheave 16 revolubly supported in a hanger 17 arranged at the upper edge and to one side of the frame 1. The end of the cord or cable is adapted to be fastened in a wire clip 18 secured to the front side of the window frame 1 adjacent to the sill 19 thereof.

Before further describing my invention, the following modifications will be noted.

In Fig. 3 of the drawing, I have illustrated the shafts 13 as being made in two sections and the ends of said sections adjustably connected together by a sleeve 20.

In Fig. 5 of the drawing, the plate 6 is made in two sections and the ends of the sections adjustably connected by a coupling member 21. It is through the medium of the construction shown in Figs. 3 and 5 that my support can be used in connection with window frames. of various widths to accommodate curtain shade rollers of various lengths.

In Fig. 6, the guide strips 4 are shaped so that, they can be secured to the front slde of the window frame, while in Fig. 7 of the drawing, a guide strip and a. rack slightly different in cross sectional shape are shown. It is. in this connection that I reserve the right to shape the guide strips for w1 ndow frames of various shapes, thus permittlng of my improvement being extensively used.

From the foregoing it will be observed that it is impossible for one end of the holder to sag or become displaced during the justment of either the plate 6 or the curtain shade roller carried thereby.

The various parts of the holder are made of light and durable metal easily shaped, assembled and applied to a window frame.

Having now described my invention what I claim as new, is

1. In a curtain shade roller support, the combination of vertical racks, guide strips carried by said racks, a plate extending from one rack to the other, and adapted to revolubly support a curtain shade roller, brackets projecting rearwardly from said plate and slidably engaging in said guide strips, revoluble shafts journaled in said brackets, pinions mounted upon the ends of said shafts and meshing with said racks, and means connecting with one end of said plate for vertically shifting the same upon said racks.

2. In a curtain shade roller support, the combination with racks, guide strips projecting inwardly from said racks, brackets slidably mounted in said guide strips, a plate connecting said brackets and having a bearing at each end for supporting a curtain shade roller, shafts revolubly mounted in said brackets rearwardly of said plate, pinions carried by said shafts and meshing with said racks, and means connecting with plate connecting said brackets and provided at each end with a bearing for supporting '"a curtain shade roller, shafts revolubly mounted in said brackets rearwardly of said plate,'pinions mounted upon the ends of said shafts and meshing with said racks, a sheave, a bracket at the top of the window frame for supporting said sheave, and a cable connecting with one end of said plate and adapted to pass over said sheave, substantially as, and for the purpose herein described.

4:. In a curtain shade roller support, a pair of racks adapted to be fixed to a window-frame, guide strips projecting toward each other and inwardly from said racks, a pair of brackets each having its inner end slidably connected in said guide strips, a plate connected to the outer ends of the brackets and projecting from said brackets,

said plate having each of its ends provided with a bearing for supporting a curtain shade roller, said brackets projecting below said plate, a pair of shafts arranged in parallelism with respect to each other and journaled in said brackets, said shafts of less length than said plate, pinions carried by the ends of said shafts and meshing with said racks, and means connected with the plate for vertically moving the same.

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

JAMES M. MAYS.
