LEWIS SHORES, OF BURKBURNETT, TEXAS.

SHADE BRACKET.

Application filed November 27, 1825. SerialNo. 71,770.

The object of this invention is the provision of means whereby an uppersand a lower shade may be supported upon a win dow casing ina manner to permit of the independent movement of either of said shades, whereby exterior light under all con ditions may be properly directed into a room.

A further object is the provision of a bracket for the rollers ofwindow shades for effectively supporting two of such rollers at, apoint approximately center of the window casing, and whereby the shades are wound upon the rollers by cords which are hold in frictional engagement with the ele ments on the said rollers in a manner to prevent the accidental turning of the rollers, and the consequent free winding or unwinding of the shades therefrom, but which may be actuated in an easy and expeditious manner when the curtains are to be wound or unwound.

A still further object is the provision of brackets for supporting thereon two shade carrying rollers and for operating the rollers in an easy manner that will dispense with the employment of the usual spring mfluenced rollers and likewise wherein the said brackets are similarly constructed and therefore interchangeable.

it-h the above recited objects in view and others which will appear as the nature of the invention is better understood, reference is to be had to the drawings which accompany and which form part of this application.

In the drawings Figure 1 is a front elevation of a window casing having shades thereon attached thereto in accordance with this invention.

Figure 2 is a greatly enlarged sectional view approximately on the line 22 of Figure 1.

Figure 3 is a perspective view of one of the brackets.

Figure 4 is a similar view of one of the frictional elements for the winding cords.

Figure 5 is a perspective fragmentary view looking toward the end of one of the rollers.

Referring now to the drawings in detail, the numeral 1 designates an ordinary window casing provided with the usual sliding sashes. In carrying out my invention I secure beneath the top rail of the casing 1, a bracket 2. The bracket has depending ends 3v provided with the usual notch or opening for the reception of the pintles of a spring influenced roller 4. The roller has the inner sides ofthe casing 1, and atthe center thereof, there are brackets in accordance with this invention. Each oftlie brackets is similarly constructed, but the opposed pair of brackets are reversely arranged for a purpose. which will be presently apparent; Each bracketincludes a -flat-plateor body 9 that is secured to the said sides of the casing. The body has its outer edge, at the center thereof, beveled, as at 10, so that one end of the bracket is wider than the other. On the edge of the bracket provided with the beveled portion 10, there are formed angularly disposed ears 11 and 12, respectively. The ear 12 has a key hole slot 13 entering from the inner edge thereof, while the ear 11 is provided with a round opening. In this opening there is arranged a revoluble bearing 14-, such as a bronze or brass eyelet 15. Inward of the opening the ear 11 is slitted longitudinally and transversely, and the metal bounded by the slit is bent outwardly in a plane with the body 9. This bent portion provides a tongue 16 and the said tongue is preferably provided with an outstanding lug 17; The upper and lower shade rollers are indicated by the numerals 18 and 19, respectively. These rollers have on their ends pintles to be received in the respective slots 10 and the opposed bearings 15 in the respec tive brackets. The shade 8 is wound around the upper roller 18 and a shade 20 is wound around the lower roller 19. The pintles of the rollers received through the. bearings 15 are formed centrally on the outer faces of wheels 21. Each wheel has a peripheral groove which is serrated, as at 22, and in the grooved wheels the pull cords 23 and 24 for the respective upper roller 18 and lower roller 19 are received. These rollers 21 have disposed over their peripheries the arched and concaved arms 25 and 26, respectively of the friction element that provides one of the important features of this invention. The arms 25' and 26 terminate in straight portions 27 which are connected, as at 28. The inner or connecting element for the arms of the friction devices are provided each with an opening 29. The straight ends 27 of the friction devices rest against the tongues 16, and the lugs 17 thereon are received through the openings 29. The upper arm 25 of each of the friction devices is of a greater length than the lower arm 26 thereof. As each of the friction devices is constructed from spring metal, the arms 25 and 26 will exert a pressure in opposite directions against the wheels 21 and consequently hold the pull cords in the grooves of the said wheels. This friction is sufficient to prevent any free or accidental movement of the rollers but is not sufficient to interfere with the free pull on the said cords.

The spring influenced roller for the upper shade 8 holds the said shade taut under all conditions, and draws the said shade upwardly to close the upper sash of the window casing when the pull cord for the roller thereof is operated. The lower shade is raised or lowered by a pull on the cord attached to the roller therefor and the simplicity of the construction and the advantages thereof will, it is believed, be perfectly apparent to those skilled in the art to which such invention relates, when the foregoing description is read in connection with the accompanying drawings.

Having described the invention, I claim In combination with a bracket plate having spaced angu'larly disposed ears, at one edge thereof, a tongue projecting inwardly from one of said ears parallel with the plate and spaced therefrom, and a bearing lug carried by said tongue of a shade roller having a grooved wheel for receiving a pull cord. a friction device for engaging said pull cord in the groove of the wheel including a U- shaped portion having an opening in its intermediate part to receive the lug on the tongue and oppositely disposed arched and concaved arms at the outer ends of the parallel portions of the whereby to embrace the cord within the groove of the wheel.

In testimony whereof I afiix my signature.
