SHADE-ROLLER CONSTRUCTION AND MOUNTING.

Application filed November 16, 1923. Serial No. 675,159.

To all whom it may concern:

Be it known that I, CHARLES Emma TO'WNSEND, a citizen of the United States, residing at Billings, in the county of Yellowstone and State of Montana, have invented new and useful Improvements in Shade-Roller Construction and Mountings, of which the following is a specification.

This invention relates to window shades and mountings therefor and has for its object the provision of a construction by means of which the shade roller may be adjusted to any height on the window casing so as to admit light and air over the top or beneath the shade as desired, the shade of course being operated and being extensible in the usual well known manner without any interference with my improvement.

An important and more specific object is the provision of a mounting of this character in which the shade roller is suspended from a window casing by means of flexible cords trained about drums on the central member of the shade roller, the arrangement being such that the cords may be wound upon the drums for adjusting the height of the shade.

An additional objectis the provision of a. device of this character which will be simple and inexpensive in manufacture, easy to install, simple to operate, positive in action, eliicient and durable in service and a general improvement in the art.

Vith the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a frontelevation of my device applied to a window,

Figure 2 is a longitudinal section through the device taken in a. vertical plane and along the axis of the roller,

Figure 3 is a perspective view of one end,

Figure 4 is a sectional view on substantially the line 44 of Figure 1 showing the parts in one position,

Figure 5 is a similar view showing the other position,

Figure 6 is a section on the line 66 of Figure 2,'l-ooking in the direction of the arrow,

Figure 7 is a fragmentary edge elevation of the control lever,

Figure 8 is av detail section similar to Figure 6 with parts omitted.

Referring more particularly to the drawings the letter A designates a window frame or casing in front of which or upon the face of which the shade is mounted. The shade B is shown as secured upon a cylindrical shade roller shell 1 which is provided internally with a spring C connected with a spindle 10 for tending to rotate the same. which is rigidly secured on the spindle 10 and which is formed in opposite sides with notches with which co-operates a lug a on an elongated pawl 5 pivoted at 6. .Vhen

The numeral 3 represents a hub the pawl 5 is in engagement with the win- 1 (low casing its lug engages within one of the notches 20 for holding the spindle 10 stationary. Associated with the end of the roller is an elongated guide bracket 14 to which the pawl 5 is pivoted at 6, and upon which is secured a disk 15 formed with notches 21 within which are adapted to engage the ordinary pawls 8 which are pivoted on the end of the shell 1 for holding the shell stationary with respect to the spindle 10. The bracket 1-it and disk 15 are formed with registeriing circular holes through which the spindle 10 is rotatable The outer end of the bracket 14; is formed with an extension 23 having a slot 24 therein.

At the opposite end of the roller I provide a U-shaped bracket 25 which includes spaced arms 26 formed with circular holes 27 which passes the extremity of the spindle 10 at the opposite end of the roller. One arm of this U shaped bracket carries an arm 29 which terminates in a lateral extension 30 formed with a slot 31 and corresponding to the bracket arm 14 and extension 23 thereon. Secured upon the outer side of the bracket 14 is a U-shaped bracket 32 which corresponds to the bracket Journaled within the brackets 25 and 32 are flanged drums 33 to which are secured and upon which are wound cords or other flexible members 34 which are suitably secured at 35 to the top of the window frame or casing.

The shell is formed at opposite points inwardly of its ferrule 36 with notches 37 within which the lug lmay engage, the pawl being thereby capable of locking either the hub 3 or the shell 1, depending upon circumstances.

In the operation it is apparent that the operator may grasp the shade B and pull it down or permit it to roll up as in the case of an ordinary shade. However by grasp ing the shade and pulling downwardly thereon and outwardly at an angle, the lug t enters one of the slots or notches thereby locks the shell so that the shade may be adjusted up or frame or casing without unrolling the shade the flexible members as being rolled onto or unrolled from the drums as the case may be. .ll 'hen the shade is held straight and pulled slightly and then released, the lug 4; moves out of engagementwitlrthe notch 37 and enters one of the notches 20. The notchesQO areso constructed lug i will hold even thoughthe wind should lift'the curtain and .roller free from the window casing, the pawlbeing releasable only by slightly rotating the shade roller with the shade pulled at an angle.

From the foregoing description and a study of the drawings it: will be apparent that I have. thus provided a simply constructed; and consequently inexpensive-shade roller device and mounting which will efficiently operate and perform the functions for which it is intended. As the parts are few it is obvious "thatthere is little to get out of order so that the device should have along life and satisfactorily perform all'of its functions.

lVliile I have shown and described the preferred embodiment of my invention it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement ofparts as will not-depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described' my invention I claim:
