' Specification of Letters Patent.

Patented Feb. 9, 1915.

Application filed March 12, 1914. Serial No. 824,230. I

T aZZ whom it may concern:

Be it known that I SIDNEY I. WHARTON, citizen of the United tates, residing at Lexington, in the county of Cleveland and State 7 of Oklahoma, have invented certain new and useful Improvements in Window Shade Rollers, of which the following is a specification. I

This invention relates to certain new and useful improvements in shade rollers. and adjustable supports therefor.

The primary object of the invention is to provide a device of the above described character, wherein the support may be adjusted to accommodate shade rollers of various lengths and to also provide, in connection with such a support, a shade roller operable by a cord to effect the raising or lowering of the shade carried by the roller, thus eliminating in the roller the expensive spring construction now common upon the market.

A further object of the invention is to provide a shade roller and support therefor, the roller being operableby a cord and the support carrying a resilient guide for the cord, said guide acting to maintain the cord in position operatively engaged with the roller to insure the eflicient operation of the device. r

' The invention. has as a further object to provide a roller, wherein the shade may be easily and readily attached to or detached from the roller. 'And the invention has as a still further object to generally improve the construction and increase the efliciency of devices-of the above described character.

' With these and other objects in view my invention'will be more fully described, illustrated in the accompanying drawings, and then sp cifically pointed out in the claims whicha re attached to and form a part of this application. 1

In the accompanying drawings: Figure 1 is a perspective view showing my improved shade roller and support in position upon a window casing, the window casing being conventionally shown. Fig. 2 is a fragmen tary erspeetive view, especially showing one 0 the shade brackets and the relative disposition of the cord guide'carried thereby. Fig. 3 is a transverse sectional view, showing the pulley mounted to rotate with the shade roller, the cord being shown in osition upon thepulley and the cord guide eing illustrated in proper operative/position.

Fig. 4 is a fragmentary longitudinal sectional view taken on the line 44 of Fig. 3 showing the disposition of the pulley upon the shaft carrying the shade roller. Fig. 5 is a fragmentary perspective view showing the manner in which the shadeis secured to the shade roller, and Fig. 6 is an end View showing my improved shade roller bracket as used to support a curtain pole.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

In carrying out my invention I employ a base rod 10 which may be formed of wood,

or any other suitable material, and which is preferably oblong in cross section as shown. The base rod 10 may be made of any desired length, being preferably of a length to extend across the average window opening, and is designed to be secured upon the outer face of the window casing above the window opening, metallic clips 11 being preferably employed to support the rod in position.

Mounted to slide upon the base rod 10, longitudinally thereof, are shade brackets 12 and 13, such brackets constituting. a air and adapted to support the shade r0 ler.

It will be understoodthat the brackets of each pair are slightly different in construcat 15-. Extending at right angles from one edge of each of the guide loops 1 1 is a bracket arm 15 which is provided with a circular aperture 16 designed to receive one extremity of the shaft. supporting the shade roller, the shaft being mounted to rotate in said apertures. The bracket arms 15 may be made of any desired fanciful conformation,

so as to enhance the appearance of the support, ,but said arms are preferably formed upon one edge with an upstanding inwardly curved portion 17, disposed to receive a curtain pole.

The brackets 12 and 13, as thus far described, are identical in construction, and it will be clear that said brackets may be positioned longitudinally of the base rod 10 -t0 conform to window openings of various widths, and so as to effect adjustment of the a strip of suitable resilient metal bent intermediate its ends to provide outwardly diverging- arms 19 and 20, the free end of the arm 19 being curved inwardly toward the arm 20, with the extremity 21 thereof disposed at substantially right angles to the body portion of the arm and terminating in spaced relation to the extremity of the arm 20. The extremities of the arms 19 and 20 are transversely curved, as shown at 22, providing grooves'adapted to receive the cord. Struck from the face of the bracket 12 is 'a lug 23, the metal forming said lug being bent over to engage the intermediate portion 24 of the cord guide 19, thus supporting the cord guide upon the bracket. The free extremity of the arm 20 is curved outwardly away from the free extremity of the arm 19, as at 25.

Supported by the brackets 12 and 13 1s a shade roller 26 which is mounted upon a shaft 27 the extremities of which are mounted to rotate in the, apertures 16 formed in the bracket arms 15. The shaft 27 may be formed of wire, the roller being bored to receive the wire, and said wire may be flattened, as shown at 28, to thus prevent rotary movement of the roller 26 independently of the shaft 27.

Mounted upon one extremity er the shaft 27 and spaced from the adjacent end of the roller 26 is a pulley 29. The pulley 29 may Thus, my improved support may be used to be secured to the shaft in any suitable manner and is preferably provided'in its outer 'face with a substantially V-shaped groove 30, adapted to receive the cord 31 by which the roller is operatedto either'raise or lower the curtain 32 carried by the roller.

Particular attention is directed to the peculiar .disposition of the cord i de 18, as best shown in Fig. 3 of the 'rawings. It will be observed that when the is mounted upon the bracket arms15, the arms 19 and 20 of the cord guide 18 are disposed to embrace the pulley 29. As heretofore stated, the arms 19 and 20 are formed of resilient material and are so spacedas to normally bear against the cord 31, to thus maintain the cord in the groove 30' of the pulley 29. Preferably, the roller 26 is of greater diameter than the pulley 29, the adjacent end of the roller acting to prevent displacement of the cord 31 over one edge of the pulley while the adjacent bracket arm 1 5"se'rves to prevent displacement of the J cord over the opposite end of the pulley.

The curtain 32 is" preferably secured to the roller 26 by the rod 33 which is held by roller 26 I to manufacture. It will I provide means whereby the cord is held in rotate with the shade roller, ving the pulley,

staples 34:, the roller being grooved longitudinally, as at 35, to receive the rod. Thus carrying the curtain. Thus, the shade may 1 be positioned at any desired height with reference to the window opening. llt will be noted that when the c rd 31 is operated to roll up the curtain, downward pull upon the intermediate portion of the cord will cause the adjacent extremity of the arm 20 of the cord guide to be sprung away from the roller, tension upon the cord causing it to bear outwardly against said arm, the ex tremity of the arm' being grooved to present 3 a smooth bearing surface for the cord. As a consequence, the tension of the cord guide upon the pulley ispartly relieved allowing it to revolve more freely.

- My improved shade roller support may be also used to support a'curtain pole 36, the

pole being placed upon the upper edges of the brackets 15 as best shown in Fig. 6 of the drawings. When, thus used, draperies suspended from the pole 36 may be arranged to extend over the shade 32, if desired, or may be allowed to hang between the shade roller supporting the shade and the rod 10 hang window curtains and where it is not of course, be omitted.

. It will therefore be seen that l provide a very simple and 'eflicient structure for the purpose set forth, such as may be adjusted to window openings of various widths, and wherein the curtain roller cord, thus obviating a spring roller construction such being more or less expensive also be seen that ll positive engagement with the pulley mounted to rotate the roller carrying the curtain, and also provide a resilient guide for the intermediate portions of the cord.

Having thus described my invention, what ll claim as new is: I

1. A device of the character described including a support, brackets carried by the support, a shade roller supported for rotation by said brackets, a pulley mounted to a cord engagand a cord guide carried by one of the brackets and engaging the cord,

said cord guide-being termed from is operated by a are strip of metal bent intermediate its ends to provide diverging resilient arms, one of said arms being laterally bent adjacent its free extremity to extend toward the pulley and each of said arms being grooved transversely at the adjacent ends t ereof to bear agzltlinst the cord upon opposi sides of the u e p 2. A device of the character described including a'support, brackets carried by the support, shade bracket arms formed on said brackets, a lip struck from one of said brackets and adapted to be bent over to en-. gage a cord guide, a cord guide carried by said lip and being formed with spaced resilient arms, a roller supported for rotation by said bracket arms, a pulley mounted to rotate with the roller and 'embracedby the arms. of the cord'guide, and a flexible element passing around the roller and engaged by the arms of the cord Iguide.

. In testimony whereof aifix my signature in presence of two witnesses.
