Application filed November 22, 1924. Serial No. 751,586.

vide a shade roller wherein the rewinding,

spring may be wound in a quick and efficient manner. 7

A further object of theinvention is toprovide a window shade roller which embodies a rotatable element associated with of a shade roller constructed in accordance with my invention.

Figure 2 is an end elevation of one of the supporting brackets used in conjunction with the invention. I

Figure 3 is a transverse sectional view taken through the roller.

Figure 4 is a side elevation of one of the brackets embodied in the invention, and

Figure 5 is a similar view of a second bracket embodied in the invention.

Referring to the drawings in detail, wherein corresponding characters of reference denote corresponding parts throughout the several views, the numeral 5 designates a shade roller having a longitudinal recess which extends from one end of the roller to a point adjacent its opposite end and arranged therein is a coil spring 7 having one end formed with an eye 8 which is secured to the end Wall of the recess 6 by means of a nail or other fastener 9 which is driven through an opening 10 formed in the roller 5 and communicating with the opening 6. A ferrule 11 is fixed to the recessed end of the roller 5 and carried thereby is a pair of oppositely movable pivoted pawls 12, either one of which may be brought into engagement with arecess 13 provided in the T-shaped member 14. The head of this T- shaped member 14 is secured to a rotatable cap or ferrule 15 which is rotatably received on the ferrule 11.

Also secured to the cap or ferrule 15 is a disk 16 having a tongue 17 struck therefrom which is offset as shown. The disk 16, head of the T-shaped member 14 and cap or ferrule 15 are connected together by a fastening 18.

A supporting bracket is designated at 19 and is ro'vlded with a keeper 20 also struck from the bracket and is disposed at ri ht angles to the tongue 17 and receives the latter as shown.

A- second bracket at the opposite end of the roller is designated 21 and receives a spindle or shaft 22 projecting from the adjacent end of the shade roller 5.

When it is desired to wind the spring 17 it is only necessary to shift the roller 5 laterally to disengage the tongue 17 from the keeper 20, and supporting the shade roller 5 with the spindle or shaft 22 in the bracket 21 the roller is held stationarily in one hand While the cap or ferrule 15 is rotated until the spring is brought to the required tension. The tongue 17 is then engaged with the keeper 20 to hold the cap or ferrule 15 stationary.

While I have shown and described the preferred embodiment of theinvention, I:

desire to have it understood that. I do not limit myself to what is herein shown and described, and that such changes may be resorted to as will not depart from the spirit of the invention or the scope of the subjoine-d claims.

What is claimed is I 1. A shade roller provided with a coil spring, a ferrule rotatably' supported on one end thereof, a T-shaped member fixed to the ferrule and having one end connected with the spring, a disk fixed to the ferrule, an offset tongue'carried by the disk, a keeper on the bracket and receiving the tongue to hold the ferrule stationary, thetongue being adapted to be disengaged from the keeper and the ferrule being subsequently rotated to adjust the spring.

2. A curtain roller having a longitudinal recess extending a part of its length, a ferrule rotatably supported on one end thereof, a coil spring in the recess having one end fixed t0 the roller an axially adjustable spring tensioning member fixed to the opposite end of the spring and having one end attached to the ferrule, a disk fixed to the ferrule, an offset tongue carried by the disk,

engaged from the keeper and the ferrule subsequently rotated to adjust the spring.

In testimony whereof I afiix my signature.

FRANK B. DUNCAN.
