ROLLER SUSPENSION FOR SHADE AND DRAPERY SUPPORTS.

Application filed December 26, 1925.

This invention relates to fixtures for windows, doors and the like, and it refers more particularly to devices for the purpose of conveniently applying curtains, draperies, and other hangings to these openings, the primary object of which is to afford a means to adjust the hangings upon a window, without the necessity of altering the window facing in any way, and further, a fixture which requires few and simple mechanical parts, reducing substantially the cost of installation.

The invention further includes a spring actuated roller, from which the drapery sup port is suspended upon a window, thereby affording a means to adjust the positionof the said support, to obtain ventilation through the upper half of the window.

Combined with the foregoing objects and advantages, the invention includes certain novel features of construction and arrangement of parts, which will become apparent, as the description proceeds, taken in connection with the figures in the accompanying drawing, to which reference will be made from time to time, wherein:

Figure 1 is a front elevational view of a window showing the invention as applied.

Figure 2.is a side view, partly in section, illustrating the manner in which the invention is suspended.

Figure 3 is an axial cross-section of the spring roller against the resistance of which the curtain and drapery support is suspended.

Figure 4 represents a perspective view of the invention.

\Vhile certain previous applications have been filed as being directed to the laterally adjustable curtain and shade supports held in suspension upon the window, the present invention will be described as embodying only the vertical adjusting means of this member, mention being made from time to time of the latter to indicate the relationship thereof to the said adjusting means.

In proceeding with the foregoing in view, the character 1 indicates a window construction according to the usual specifications, and at the top thereof an extensible roller 2 is screwed or otherwise suitably applied by being equipped with roller housings 3, situated upon either end thereof having in tegral therewith screw plates 4, for the ap- Serial No. 77,705.

plication of the roller to the window as described.

ttention is directed to Figure 3 of the drawings showing a cross-sectional view of the rollers 2. As obvious in this figure, extension of the roller is attained by reason of the intermediate tubular member 5, into either end of which the roller sections 2 are inserted. This extension serves to equip the roller for windows of varying widths. TVithin either of the interior tubular members 6, rotatably disposed within the outer shells 2, a stout coil spring 7 is disposed, having its ends securely embedded in a plug 8, mounted in the outer shells 2, while its opposite end is embedded in a plug 9, securely affixed within the interior tube 6. The ends of the tubes 6 extend through the housings 3 on either end of the roller forming an axis about which flexible fabric straps 10 are wound, which depend from the housings 3 to be secured to plates 11 directly below the horizontal support 12, but in rigid relationship therewith, a. description of which will be given later.

Resistance imparted by the springs 7 to the straps 10 is obvious. The housing 3, likewise the roller shells 2 being non-rotatable with respect to the window, permits the inner tubes 6 to rotate against the action of the spring 7 when the straps 10 are moved. Thus when the drapery support 12 is at its lowest point upon the opening, resistance on the spring 7 is greatest.

In event greater resistance of the spring 7 is required by reason of additional drapes being applied, to increase the weight upon the supports 12, winding keys 16 are supplied upon either end of the roller as illustrated, actuation of these keys permits the spring to either be wound or adjusted to equal resistance.

A dog and ratchet mechanism of usual construction is applied exteriorly of the housings o to control the movement of the inner tubes 6 and to permit the sup 3ort 12 to be suspended permanently at any desired point upon the window.

As a guide for support 12, tracks 13 are affixed in alinement upon both sides of the window which receive conforming slides 14, adjustably affixed to the back of support 12, and to which the plate 11 is attached. The support 12 being horizontally adjustable, it will be seen that the latter may be moved to permitthe slides 14 toreceive the tracks, thus to permit frictional movement up and down the window, depending upon the said straps l0.

Movement of the support upon the tracks against the action of the roller, is efi'ected by the depending straps 15, centrally disposed as shown in Figure 1.

It should be understood that it is not desired that the invention be limited to the specific disclosure herein set forth, and that certain modifications may be resorted to as fall within the meaning and scope of what is herein claimed.

I claim:

1. In an adjustable shade and drapery support, a roller composed of alined shells each having a housing at its outer end, a tubular connecting member receiving the inner ends of the shells, a rotatable tubular member in each shell having the outer ends thereof extending into the respective housby the straps.

2. In an adjustable shade and drapery support, a roller having an outer shell, rotatable tubular members in the shell having their outer ends extending beyond the outer ends of the shell, flexible straps secured to the outer ends of the tubular members, a plug in each tubular member, a pair of plugs in the shell, coil springs in the tubular members connected at their outer, ends to the plugs in said members and at their inner ends to the respective plugsof the shell, and a curtain and drapery support connected to the straps.

In testimony whereof I aftix my signature.

LULA H. ROBINSON.
