WINDOW-SHADE ROLLER.

mere-a2.

Application filed February 8, 1916. Serial No. 77,031.

To all whom it may concern Be it known that I, FRANKLIN A. DAW- SON, a citizen of the United States, residing at Coats, in the county of T-Io-rnett and State of North Carolina, have invented certain new and useful Improvements in Window-Shade Rollers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in shade and curtain fixtures and it has for its object, among others, the provision of a bracket adapted to be secured directly to a casing or window frame. the bracket being constructed of a single piece of sheet metal so. fashioned as to provide a suitable bearing for the roller pintles and affording, in addition, means whereby the curtain cord used in raising the curtain is passed through a suitable guide above the roller and so positioned with reference thereto as to avoid contact of the cord with the roller.

The invention relates particularly to that class of devices in which the use of a spring is obviated and in which provision is had for locking the curtain at any desired height.

The invention has for a further object the provision of a curtain fixture of the character mentioned in which a single operating cord suflices for operating the device, thus simplifying the construction in which two cords are required.

The invention has for a further object the use of novel means for unlocking the roller from the bracket and permitting its being rotated in either direction, either to raise or lower, the use of the usual contained spring being omitted and the construction being such as to permit the roller to fall into its locked position at once upon the release of the rotating means.

To these ends and to such others as the invention may pertain, the same consists in the novel construction and in the peculiar arrangement, combination and adaptation of parts. all as will be more fully hereinafter described, shown in the accompanying drawings and then specifically defined in the appended claim.

Specification of Letters Patent.

t t lit The invention is clearly i1 the accompanying drawings which, with the numerals of reference marked thereon, form a part of this specification and in which:

Figure 1 is a front view of the upper portion of a window with my improved curtain fixture in place therein. Fig. 2 is a like view of the upper portion of a window with my improved curtain fixture in place therein. Figs. 3 and 4 are enlarged details in perspective of the curtain brackets used at opposite ends of the curtain.

Reference now being had to the details of the drawings by numeral, 1 represents a window frame or casing and 3 is a curtain roller upon which is mounted a shade-2 in the usual manner. Projecting from the opposite ends of the roller 3 are pintles 4 and 5 mounted to rotate in the angular opening 6 in the bracket 7 at one end of the roller and the vertically disposed slot 7-in thebracket 8 at the opposite end of the roller.

It will be noted that in mounting the roller a space is provided between the end of the roller adjacent to the bracket 8 for the reception of the cord 9, one end of which cord is secured to the roller and, after being secured to and wound about the roller, is passed upward through an eyelet or cord guide 10 in the forwardly extended end of the horizontal extension 11 of the bracket 8.

The brackets are provided with perforations or openings 12, 12 for the reception of screws used in securing them to the win dow casing. It will be noted that the main portion of the opening 6 in the forwardly extended bracket supporting portion 13 is rectangular and from which is a portion extending downwardly.

From the foregoing description of the construction of the device, its operation will be readily understood. It will be noted that the bottom of the bracket 8 is such as to provide in a single element provision for journaling an end of the roller and also for the passage of the curtain cord through a forwardly extended portion of the bracket above and in advance of the roller, thus dispensing entirely with an additional roller support or" extra roller commonly employed in connection with curtain fixtures of this character. It will also be noted that the bottom of the pintle opening 6 is such as to permit the curtain to be rotated readily and yet locked automatically at any point desired. When it is desired to raisethe ourtain, a slight movement of the curtain will serve to disengage the pintle from the aperture 6 and permit the curtain to be moved upward by the use of the operating cord 9.

Having thus described my invention, what 1 claim to be new and desire to secure by Letters Patent is A bracket for shade fixtures formed of a metallic plate having openings to receive its securing means and formed with a forwardly extended portion with vertical opening with straight sides and a straight-sided lateral opening leading therefrom, a horizontal extension from the top of the body ofv said bracket extending I forward and adapted to guide a single cord, said cord being adapted to be connected with and to wind in opposite directions upon a shade roller, whereby, when the cord is pulled upon, the flattened pintle of the shade roller, which normally rests in the vertical portion of said opening, is raised and moved forward out of alinement with said vertical opening and into the lateral opening and revoluble therein, and automatically returnable to the vertical opening when pressure on said cord is released.

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

FRANKLIN A. DAWSON.
