WINDOW-SHADE SUPPORT.

Specification of Letters Patent.

Patented Julyfi, 1%15.

Application filed May 8, 1914. Serial No. 887,319.

To all whom it may concern:

Be it known that I, AUGUST F. LUzzI, a citizen of the United States, residing at Name, in the county of McLennan and State of Texas, have invented certain 'new and useful Improvements in Window- Shade Supports, of which the following is a specification.

This invention relates to shade holders of that class in which the shade roller is adjustable vertically of the window so that light may, when desired, be admitted above the roller, this adjustment or manipulation of the roller being in addition to the usual rotation of the same so that the quantity of light admitted into a room may be regulated as may be desired.

The object of my present invention is to provide improved means for supporting the shade roller, and also to provide improved means for adjusting the same.

A further object is to provide means whereby the roller will be held against accidental displacement from its supports, and a still further object is to provide means for holding the shade in any position in which it may be set.

These several stated objects and such other incidental objects as will appear as the description of the invention proceeds are obtained in a device of the character illustrated in the accompanying drawings, and the invention consists in certain novel features which will be hereinafter first fully described and then more particularly pointed out in the claims following the description.

In the accompanying drawings: Figure 1 is a front elevation of a window having my improved shade applied thereto; Fig. 2 is a section on line 2 of Fig. 1; Fig. 3 is a detail perspective view of one of the corner brackets; Fig. 4 is a detail perspective view of another corner bracket; Fig. 5 is a'detail perspective view of a third corner bracket; Figs. 6 and 7 are elevations of the'roller supports; Fig. "8 is an edge view of one of the roller supports; Fig. 9 is a detail perspective view of the bracket and roller cooperating therewith, whereby the shade is held in its adjusted position; Fig. 10 is a detail sectional view of one'end of the roller; and Fig. 11 is a detail perspective view of the opposite end of the roller.

In carrying out my present invention, I secure upon-the window frame, at the top inserted into the frame to secure the brackets in position. The wing 2 of the bracket is provided with spaced apertured lugs or ears 4 which may conveniently be formed by striking up a portion of the metal constituting the wing, and the apertures in the said lugsare in alinement to receive the end of a guide and supporting rod. as shown. The free vertical edge of'the wing 2 is also provided with an eye or sleeve 5 through which the guide and supporting rod passes, and the brackets will be placed upon the frame in such relative positions that the eye 5 of an upper bracket will be in vertical alinement with the corresponding eve of the lower bracket at the same side of the window frame. A guiding and supporting rod 6'is provided at each side of the window frame and the intermediate portion of each rod is inserted through the vertically alined eyes 5 at that side of the window while the extremities of the rod are bent inwardly and pass through the perforated and spaced ears 4.

The bracket shown in Fig. 5 is preferably secured to the window frame at the lower left hand corner of the same, and in Fig. 1 this bracket is indicated by the numeral 7 The bracket shown in Fig. 4 is secured to the upper left hand corner of the window frame and is indicated by the reference numeral 8 in Fig. 1. It will be noted that the terminal 9 of the rod 6 between the ears 4 of the bracket 7 is clear, while the upper terminal 10 of the rod 6 has mounted upon the same between the ears 4 of the bracket 8 a grooved pulley 11. The bracket shown in Fig. '3 is secured to the upper right hand corner of the frame and is indicated by the reference numeral 12. It will be seen at once that the upper terminal 13 of the rod 6 at the right hand side of the window has mounted upon it between the ears 4 of the bracket 12 two grooved rollers or pulleys 14. The bracket shown in Fig. 9 and designated by the reference numeral 15has its body between the spaced ears 4 formed into an outwardly and upwardly projecting curved lip 16, as shown, and a single roller 17 is mounted upon the extremity 18 of the right hand rod 6. This roller 17 is substantially conical in form and around its conical surface it is provided with a spiral bead or groove.

The shade roller is mounted at its ends in suitable supports or carriers which are connected to cables or cords 19 and 20, the cable 19 passing upwardly from the shade supports or carriers to the bracket 8 and then extending over the roller or pulley 11 and across the top of the window to the bracket 12 where it passes over one of the rollers 14 and then is carried downward to a convenient length. The cable 20 passes upwardly from the shade support or carrier to the bracket 12, and then over the roller 14 which is not engaged by the cable 19, and then depends from said roller to be secured to the end of the cable 19. From the junction of the cables 19 and 20 a third cable 21 passes to and through the bracket 15. The cable 21 will ride over the lip 16, between the same and the conical. roller 17 and it will be readily understood that if the cable or 'cord be forced between the wider end of the conical roller 17 and the lip 16 it will bind and be held against movement, whereby the shade roller will be held at that point 1 of the height of the window to which it may be adjusted.

It will be obvious that if the cable be disposed at the smaller end of the roller, the roller will not engage the cable to bind it against the lip 16 and the operator may then readily bring the shade roller to any desired point. After the shade roller has been adjusted the cable may be shifted laterally to the larger end of the roller 17 and forced between the same and the lip 16 between which it will bind and will be held. The cable will, of course, be engaged in the groove of the conical roller and the pitch of the groove is such that rotation of the roller, due to a pull exerted on the cable by the shade roller and its supports, will feed the cable toward the larger end of the roller and thereby react to bind the cable more firmly against the lip 16.

The shade roller 22 may be of any well known. construction, and is carried by brackets or supports 23 at its opposite ends. These brackets are preferably in the form of circular disks provided at vertically diametrically opposite points with outstanding lugs 24 which slidably engage the guide rods 6, as will be readily understood. The :disks are constructed centrally with slots or elongated openings 25 which are large enough at their outer extremities to readily admitthe ends of the pintles 'or other journal members at the ends of the roller, and at their inner ends the said slots are formed with notches 26 in their lower walls or edges disks adjacent said slots or notches rare dogs wall of the slot, and the dog may then swing 27 which have their inner ends formed into hooks 28 adapted to engage over the pintles or journal members of the shade roller and thereby retain the same in position within the notches and slots. The outerends of the said dogs are provided with openings 29 to permit the attachment of the cables 19 and 20 thereto, and the shade roller is thus suspended by the said cables and the said dogs. While the-weight of-the shade roller 7 and the shade mounted thereon will tend to hold the dogs in engagement with the pintles or journal members, I provide positive means for preventingthe disengagement of the dogs and to this end I may strike from so the body of the dog near the hook 28a small projection or tooth 30 which is adapted to engage against the upper wall of the slot 25 and thereby prevent the upward movement of the hook end of the dog.

When it is desired to remove the roller from its supports for any reason, the hook end of the dog is pressed laterally slightly so that the tooth 30 may clear the upper about its pivot so that the hook may be raised clear of the pintle or journal member of the roller. The dog may also be held against disengagement from the pintle or journal member by providing a tooth or projection 31 upon'the disk 23 against which the lower edge of the dog may engage. When it is desired to release the roller the rear end of the dog will be sprung'laterally so as to permit it to clear. the projection 31, as will be readily understood. It will, of course, be understood that the dogs 27 are formed of sheet metal, and will preferably be resilient so that while they will not be apt to be accidentally released from the shade roller they may be readily released when such action is necessary.

The roller 22 is provided at .1one end with a cylindrical support which may be a screw-- or nail where extreme economy in produc- 11 tion is desirable. This cylindrical pintle or journal member 32 is provided with an annular groove or spaced annular flanges, as shown at 33, and the hook end of the adjacent dog 27 engages the said pintle between the said flanges. Axial movement of the pintle and the roller will thus be prevented. At the opposite end of the roller, which carries the actuating spring, the journal mem-- ber 34: is angular in cross section and is pro vided in its upper and lower edges with small notches 35 which are engaged by the 7 adjacent dog 27. These notches will permit a slight lateral movement of the member 34 7 relative to the roller so asto accommodate the variations in the axial length of the spring asit winds and unwinds.

It will be readily'seen from the foregoing description, taken in connection with the accompan'ying drawings, that I have provided 139 a shade roller support which may be readily adjusted to any desired height and by which the shade roller will be positively carried without interfering in any way with the usual operation of the roller. The construction of the different partsis such that they may be produced economically and will possess the desired strength and durability. Moreover, they may be readily placed in position and assembled, and when in place will not mar or detract from the sightly appearance of the window frame.

The brackets are preferably formed of sheet metal and are, therefore, very light and cheap. In assembling the parts, the guide rods may have their ends engaged in the perforated ears 4 and will thereby serve as gages to quickly position the upper and lower brackets in proper spaced relation. After the brackets have been secured to the window frame the projecting lips or tongues at the free edges of the brackets may be easily rolled around the guide rods to form the sleeves 5 and thereby prevent detachment of the guide rods.

Having thus described the invention, what is claimed as new is 1. The combination of guide rods, supports slidably mounted upon the said rods, a shade roller extending between the said supports and provided at its ends with j ournal members extending into the supports, dogs pivoted on the supports and having their front ends engaging over said journal members, and suspending cables attached to the rear ends of said dogs and passing upwardly therefrom.

2. The combination of guide rods, supports slidably mounted on said rods and provided with slots, a shade roller having journal members at its ends adapted to seat in the inner ends of said slots, dogs pivoted upon the supports and having their front ends engaging over the said journal members to retain them in the slots, and suspending cables attached to the rear free ends of said dogs and extending upwardly therefrom.

8. The combination of guide rods, supports slidably mounted thereon and provided with transverse apertures, a shade roller provided at its ends with journal members seated in said apertures, dogs pivotally mounted upon the supports and having hooks at their front ends to engage over the said journal members and retain them seated in said apertures, and suspending c:.- bles attached to and extending upwardly from the free rear ends of the dogs.

4. The combination of guide rods, supports slidably mounted on said rods, a shade roller extending between said supports and provided at its ends with journal members adapted to engage the same, dogs pivoted upon the supports and having their front ends fitting over the said journal members, means to prevent release of the dogs from the said journal members, and suspending cables attached to and extending upwardly from the free rear ends of the dogs.

5. The combination of guide rods, supports slidably mounted thereon and provided with slots extending outwardly from the centers of the supports, a shade roller extending between the supports and provided with journal members at its ends adapted to seat in the inner ends of said slots, dogs pivoted upon the supports and having their front ends provided with hooks to engage over said journal members and with lateral projections adapted to engage against the upper walls of the adjacent slots, and suspending cables secured to and extending upwardly from the rear free ends of the dogs.

6. The combination of upper and lower brackets having outstanding wings and provided with openings in said wings, one of the lower brackets having an outwardly projecting lip at the lower side of the opening therethrough, guide rods extending between the upper and lower brackets, a shade roller slidablv mounted on the guide rods, an operating cable connected with the shade roller and passing over the said lip, and a conical roller mounted in the opening adjacent the said lip and provided with a spiral groove to engage the cable.

In testimony whereof I aflix my signature in presence of two witnesses.
