SHADE-SUPPORTING DEVICE.

Specification of Letters Patent.

Patented Jan. 14, 1913.

Application led March 1, 1912. Serial No. 680,791.

To all whom t may concern Be it known that I, BENJAMIN J. JAco- WAY, a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented new and useful Improvements in Shade-Supporting 'tion is the provision of a simple and efficient device of this character wherein the operating mechanism for controlling the movement of the shade may be placed at any desired point on the frame irrespective of the position of the shade supports.

A further object of this invention is the provision of a device of this character which is so constructed that it may be used either inside the frame adjacent the sash or on the outside of the frame, as shown in the drawin s.

(lnother object of the invention is to provide novel means for securing the guide rods for the shade brackets and to construct these parts with a minimum amount of material and secure the guide rods therein without the use of fastening devices, such as set screws, or the like.

Another, and one of the most important objects of the invention, is to provide means whereby the tension of the spring in the shade roller may be readily adjusted without removing the roller from the brackets.

Further objects of this invention will appear as the following specic description is read in connection with the accompanying drawing, which forms a part of this application, and in which j Figure 1 is a front elevation showing the device applied to a window frame and with the shade in raised position. Fig. 2 shows a side elevation. Fig. 3 is a detail vertical sectional view through the upper rod and one of the pulley holders. Fig. 4: is a perspective view of one of the upper rod and pulley holders with the rod and pulleys removed therefrom. Fig. 5 is a detail vertical sectional view on the line 5-5 of Fig. 3. Fig. 6 is a detail vertical sectional view through the automatic adjuster grip and through the lower rod holder. Fig. 7 is a plan view of the rod and pulley holder blank. Fig. 8 is a similar view of the automatic grip. Fig. 9 is a detail side elevation showing in dotted lines the position of the spring shaft of the shade roller when the tension is being adjusted.

Referring more particularly to the drawings, 1 represents the ordinary window frame in which the sashes 2 and 3 are mounted as is usual. Secured to the upper portion of the frame on either side thereof are similarly constructed rod supporting members 4: which are constructed from the blanks or plates shown at 5 in Fig. 7 and are bent up into the form shown in Fig. 4. Suitable ears 6 and 7 are struck up from the plate to receive a pulley shaft 8 upon which are journaled the rope pulleys 9 to be hereinafter described. The plate is bent upon the line 10, Fig. 7, and then again upon the line 11, suitable lugs 12 being struck up from the,

last portion and having apertures 13 therein to receive the guiding rod 14. When the rod is applied to the lugs or ears 12, they are arranged in parallel relation, as shown in dotted lines in Fig. 5 and are subsequently bent to the position shown in full lines in said ligure so as to bind upon the rod and prevent its movement in either direction. As shown in Fig. 1, one of the rods 14: is connected Jc hro'ugh a union 15 to an extension 16, whose lower end is secured against movement in either direction by a supporting member 17 which is similar to the union 15 in that it has the rod receiving ears 18 but in this lat-ter instance, both are bent in the same direction to prevent any depression of the extension 16, whose upward movement is prevented by its contact with the upper point upon the frame, not necessarily forming a continuation of the rod 14, is an automatic grip 19 which is constructed from the blank 20, shown in Fig. 8, and bent up into the form shown in section in Fig. 6. This blank consists of the ears 21 which are bent from the body so as to lie in parallel relation and are apertured to receive the pulley shaft 22, upon which the cable pulley 23 is journaled. Projecting at right angles from the ears 21 are ears 24 and 25, the former being provided with a rod receiving aperture 26 of somewhat larger diameter than the rod, and the latter being provided with a notch 27 of a similar size to and adapted to receive the rod. The ears 24 and 25 are bent slightly beyond the parallel so that they converge.

`Passing over the Apulley 23 and having one of its free ends secured to the union 15 in any suit-able manner is an operating cable 28, whose opposite free end is connected through a union 29 to the looped ends of an operating cord 30, one leg of which is passed over the inner pulley 9 and down to its connection with the shade roller bracket 31. The opposite leg of this cord is carried over the outer pulley 9 and across t-he upper portion of the frame to the outer pulley 9 of the opposite rod supporting bracket and down to connection with the shade supporting bracket 32. These shade supporting brackets are constructed of plates 33 having longitudinally extending parallel ears 34 which are coiled into bearings which surround the rods 14 and are guided thereon. The shade roller which is shown at 35 is provided with a headed stud at one end indicated at 36, which is preferably screwed intovthe end of the roller in the form of an ordinary screw and which takes the place of the usual pintle on one end of the roller. A t the opposite end of the roller, the squared spring shaft which is shown at 37 project-s through the bracket and is provided with the washer 38 and a cotter key 39 to prevent displacement of the shaft in the bracket and also to prevent the bracket from swinging upon the rod. The brackets 31 and 32 are both identical in form, that is, each has a circular aperture 40 and a tangential slot 41. The bracket 31 is, however, in reversed position upon the rod, or in other words, the slot 41 is projected above the circular aperture 40 while in the bracket 32, the slot is projected below the aperture,

` thus, by producing the bracket in this manner, there is only one die required to form both. By raising the squared shaft of the roller into the circular aperture 40 of the bracket32, the entire roller may be rotated thus if the curtain is unwound and the shaft forced into the circular aperture 40 and the curtain wound up and the shaft again dropped into the slot 41. It will be seen that the tension of the spring will be increased upon the next operation of the shade. By reversing this operation, the tension, of course, may be decreased.

It will be readily understood that when the automatic grip is released, that the weight of the shade upon the cables will raise the outer end of the automatic grip so as to cause the walls of the aperture 26 to bind upon the extension rod 16 and lock the automatic against upward movement. By depressing the outer or pulley end of the automatic grip until the ear 25 engages the rod, the automatic grip may be moved up or down, as desired, so as to adjust the position of the shade on the rods 14. The brackets 4 and the supporting unions 15 limit the upward or downward movement of the shade brackets, while the unions 15 and the supporting member 17 limit t-he upward or downward movement of the automatic grip, as will be readily understood.
