This invention relates to bracketsjand, more particularly to that in which a pull-cord is used in connection witha curtain fixture that may be raised and lowered'by the pull-cord.

The object of my present invention is to provide a bracket ofthe most'simple mechanical nature, comparatively inexpensive to manufacture, and wherein the cord riding over guides and supported'thereby is not subject to cutting action and jamming.

With the above and other objects and advantages in mind, attention is called to the accompanying drawings, forming a part of this application, and in which like numerals are employed to designate like parts throughout the same.

In the accompanying drawings:

Fig.1 is a perspective view of the bracket looking at the end, top and front thereof.

Fig. 2 is a perspective view of the bracket looking at the opposite end, top and back thereof.

Fig; 3 is a front elevation of part of a window casing. showing brackets secured to the upper corners thereof, a pull-cord supported by the brackets and curtain rod supporting carriers suspended from the ends of the cord.

Fig. .4 is a vertical sectional view taken on line 4-1 of. Fig. 3, looking in direction of the arrow.

Fig. '5 is a top plan view of the bracket embodying the features of my invention.

In the drawings, wherein for the purpose of illustration, is shown a preferred form of pullcord bracket embodying the features of my invention. Y

The bracket, as clearly shown in Figs. 1 and 2, comprises an inverted U-shaped member having a flat back wall [0, a front wall ll spaced from the back wall to provide a pull-cord space I2 therebetween, as shown in Fig. 4. A top wall l3 having an elongated opening M, as shown in Figs. 1 and 2, integrally connects the upper end of the back and front walls. A pair of pull-cord guide members, or stationary sheaves, designated l5 and I6 are arranged in horizontal spaced apart relation within the bracket providing thereby a vertical pull-cord receiving passage I! therebetween, as shown in Fig. 5. The pull-cord guide members l5 and I6 are each tubular, as shown, as they are preferably extruded from the back and front wall material to provide the bracket with a pair of fastener receiving openings [8 for securing a bracket to each of the upper corners of a window casing designated l9, as shown in Fig. 3. The extruded pull-cord guides, or stationary sheaves l5 and 16 provide a smooth curved surface for the pull-cord to ride on. The

I 7 Claims '(Cl.254--190) pull-cord guides and I6 are shown as partly extruded from both the back and front walls l0 and II and'abutting at their inner ends. However, each guide member 15 and It may, if desired, be extruded from one ofthe bracket wallsv only, and in such case, the free end of each guide member will abut the opposite wall.

The lower end portion of the front wall ll of the bracket is bent outwardly, as at 20, at a de-- sirable angle to the plane of the remainder of the wall I I to provide a widened mouth for the space l2, and to serve as a stop-element for a curtain fixture carrier when raised to its uppermost position by means of a pull-cord.

For the purpose of illustration, I have shown in Fig. 3, a pair of pull-cord brackets associated with a pair of like cord suspended curtain fixture supporting carriers designated, generally, as 2| and 22. The left carrier is designated 2| and the right carrier is designated 22. The curtain fixture supported at its ends by the carriers is designated, generally, as 23.

The left end of the pull-cord designated 24 is anchored at its ends to the upper end of carrier 2| and rides over the guide member l6 of the pullcord bracket at the left side of the window frame. The cord then spans the gap between the left and right pull-cord brackets and rides over the guide member l5 of the right pull-cord bracket. The cord descends therefrom to loop and return upwardly to ride over the guide member it of the right pull-cord bracket. The cord then descends and the end thereof is anchored to the upper end of the carrier 22.

By simply pulling on the-looped end of the cord, raising operation of the curtain rod supporting carriers is eifected. Whereas, releasing pull on the cord, lowering of the curtain rod supporting carriers is effected.

It is to be distinctly understood that the form of my invention, herein shown and described, is to be taken as a preferred example of the same,

and that the invention is subject to various forms and modifications which come within the scope and spirit of the appended claims.

What I claim is:

1. A pull-cord supporting bracket comprising a folded sheet of metal to provide spaced apart back and front plate-like members and having an elongated opening at the fold portion of the bracket, and horizontally spaced apart tubular means integral with the members and disposed therebetween to provide cord riding surfaces and openings to receive fastening devices to secure the brackets to a window casing.

'2. A bracket as defined in claim 1, wherein the lower edge portion of the front plate-like member is bent outwardly at an angle to the plane of the member.

3. A bracket as defined in claim 1, wherein the front plate-like member is disposed at a slight angle to the back member, and wherein the lower edge portion of the front member is bent outwardly at an angle to the front member.

4. A pull-cord supporting bracket adapted to be secured to the upper corner portions of a window casing comprising a pair of spaced opposed plate-like members, means connecting the members at their upper ends and providing an elongated opening therebetween, a projection bent outwardly and downwardly from one of the members, and opposed tubular projections extruded from the members toward each other for inner end contact to provide smooth external cord riding surfaces.

5. In a bracket of the class described, a bracket body inverted U-shaped in end elevation providing a front and a back wall and having an elongated opening in the top thereof, the front wall having its lower edge bent outwardly at a desired angle, and spaced tubular cord supporting means 4 integral with and arranged between the front and back walls.

6. A pull-cord supporting bracket comprising an inverted U-shaped sheet metal body providing thereby a front wall and a rear wall in spaced -relation, the body having an elongated opening providing therebetween an elongated opening at v the top of the bracket, and horizontally spaced apart means, tubular in formation, between the front and back plates to serve as stationary sheaves for a pull-cord to ride over and to provide openings through the sheaves to receive fastening devices for securing the bracket to the window casing.
