ADJUSTABLE SHADE-ROLLER BRACKET.

Specification of Letters Patent.

Patented Feb. 6, 1912.

Application filed December 10, 1910. Serial No. 596,647.

To all whom it may concern Be it known that I, CHARLES MASON, citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in -Adjustable Shade-Roller Brackets, of which the following is a specification.

This invention relates to supportlng brackets for shade rollers and has for its object the provision of a comparatively simple and thoroughly eflicient device of this character, the construction of which is such that the bracket may be readily attached to a window frame without the employment of screws, nails and similar fastening devices.

A further object of the invention is to provide a bracket, capable of being adjusted vertically of a window frame and which will admit of the shade roller being reversed without the necessity of reversing said bracket.

A further object is to provide a bracket, the shade roller of which may be fitted thereto without the employment of a chair, step ladder or the like for the operator to stand on when hanging the shade roller.

A further object is to provide a supporting bracket including pivotally united members adapted to frictionally engage the walls of the sash receiving channel or run, the construction of the bracket being such that it may be adjusted vertically of the window frame without interfering with the sash cord or pulley.

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efficiency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a transverse sectional view of a portion of a window provided with a shade supporting bracket constructed in accordance with my invention; Fig. 2 is a detail perspective view of a portion of one side of taching the bracket thereto Fig. 3 is a top plan view, partly in section, of one of the roller supporting brackets detached; Fig. 4 is a rear elevation of the bracket.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved supporting bracket form ing the subject matter of the present invention is principally designed for attachment to window frames and similar closures and by way of illustration is shown in connec tion with a window of the ordinary construction, in which 5 designates the frame having guiding channels or runs 6 formed therein for the reception of the sashes 7, the latter being provided with the usual sash cords 8 extending over pulleys 9 for connection to the sash weights.

The device comprises co-acting members 10 and 11, each preferably formed of a single piece of fiat metal having its opposite longitudinal edges concaved at 12, said members having their central portions intersecting and pivotally united at 13. the metal forming the opposite ends of the members 10 and 11 being bent laterally to form angularly disposed flanges 14- adapted to bear against and positively engage the walls of the adjacent run or channel 6, thus to hold said bracket in position on the window frame. The members 10 and 11 are also formed with substantially rectangular openings 15 adapted to receive the pins or trunnions of the shade roller, indicated at 16, there being preferably four of such openings formed in each bracket, as shown. The metal forming the flanges 14 is bent laterally to produce substantially horizontally disposed lips 17, the free edges of which are toothed or serrated so as to bite into the walls of the run or channel 6 and thus assist in holding the bracket in adjusted position.

The metal forming the lower ends of the members 10 and 11 is cut or severed and rolled upon itself to produce depending finger pieces 18 by means of which said members may be drawn together so as to permit the bracket to be readily inserted within the run or channel. 6. Spaced from the inner face of the member 10 and secured in position on the bracket by the pin 13, is a disk 19, between which and the bracket is a window frame, showing the manner of at- I interposed a coil spring 20. The opposite ends of the wire forming the spring 20, are extended on diverging lines, while the free ends of the wire are bent to form terminal angularly disposed fingers 21 adapted to enter suitable openin s 22 formed in the members 10 and 11, some of said openings being formed in the flanges 14, as shown. The tension of the spring 20 is such as to forcethe upper ends of the members 10 and 11 apart so that when the bracket is inserted in the run or channel 6, the spring will force the members laterally or apart so that the teeth 17 thereof will bite into the walls of the channel. Thusit will be'seen that by grasping the finger pieces 18 and forcing the latter together, the bracket may be ad justed vertically of the window frame, the

. spring serving to force the members 10 and 11 apart and thus secure the bracket in different positions of adjustment. It will also be noted that the construction of the bracket is such that the same may be adjusted vertically of the run or channel 6 without interfering with the pulley 9 and sash cord 8.

It will of course be understood that one of the brackets will be seated in the groove or. channel 6 on each side of a window frame so as to support the opposite ends of the shade roller 16. In hanging a shade roller, one of the brackets is moved to a position slightly below the level of the other bracket and the pins or trunnions of said roller inserted in the openings 15, after which the brackets are moved to a posit-ion in horizontal alinement with each other, and said brackets together with the shade roller raised or lowered to the desired position on the window frame.

It is obvious that in order to remove the roller, it is merely necessary to drop one of the brackets to a position below the other, when the pin or trunnion of the roller may .be readily detached therefrom so as to permit the shade roller to be taken down.

Particular attention is called to the fact that by making the brackets in the manner described, both brackets may be lowered to permit the hanging of the shade roller, without the necessity of the operator standing on a chair, step ladder or the like to effect the hanging of said roller.

It will also be noted that the sashes may be raised or lowered without interfering with the brackets, and that when thus raised or lowered, said sashes will prevent rain or snow from driving through the window and wetting or otherwise injuring the curtain.

By making the openings 15 substantially rectangular in shape, the roller may be readily reversed when necessary, without reversing the brackets, while by forming a plurality of openings in the brackets, the position of the roller on the brackets may be varied at will according to the conditions under which it is used,

The device is extremely simple in con struction and may be manufactured and placed on the market at a comparatively small cost.

Having thus described the invention, what is claimed as new is:

1. The combination with a window frame having sash cords and provided with sash receiving channels, of brackets fitted within the channels in front of the sash cords and provided with means for supporting a shade roller, each bracket including pivotally united plateshaving their free ends bearing against the adjacent walls of the channels, and springs encircling the pivotal axes of the plates of the brackets and having their opposite ends secured to the free ends of said plates for normally forcing the latter into engagement with the walls of the channels.

2. A supporting bracket for shade rollers including pivotally united members 'providecl with depending finger pieces and having their free ends bent to form laterally extending flanges, there being openings formed in said members for the reception of the trunnions of a shade roller, and a spring having its intermediate portion encircling the pivotal axis of. said members and its opposite ends secured to the free ends of the members forforcing the flanges into engagement with a support.

3. A supporting bracket for shade rollers including pivot-ally united members, each formed from a single strip of flat metal h avingits longitudinal edges bent to produce angularly disposed flanges, the metal at said flanges being bent laterally to produce serrated lips, there being openings formed in said members and perforations arranged near some of the openings, the lower end of each member being bent to produce a depending finger piece, a disk secured to the pivot pin, and a coil spring having its intermediate portion coiled around the pivot pin between the disk and the rear faces of said icmbers and its opposite ends provided with terminal fingers extending through the adjacent perforations.

In testimony whereof, I aliix my signature in presence of two witnesses,

CHARLES MASON. [Ls] \Vitnesses P. J. HOLMES, J. M. HoYT.
