UNITED STATES JOHN P. HALL," OF PATROON, TEXAS.

WINDOW-SHADE ROLLER.

Application filed June 14, 1923.

[0 all whom it may concern.

Be it known that I, JOHN P. HALL, a citizen of the United States, residing at Patroon, in the county of Shelby and State of Texas, have invented new and useful Improvements in. VVindow-Shade Rollers, of which the following is a specification.

This invention relates to window shade rollers and has for its primary object the provision of a novel construction of means for holding the shade in any given position, adapted for use. in the place of the usual ball and ratchet mechanism, with which said rollers are now equipped.

More specifically started, the invention contemplates the provision of a grooved member associated with one end of the roller, and has secured thereto a. flexibl element which when unwound from. the grooved member rotates the roller a 'ainst the tension of its spring to roll the shade, the grooved member being designed to cooperate with a latch element for holding the shade in a given position, and which when released will allow the roller=to unwind the shade thereon.

In carrying out the invention it is my purpose to construct a window shade bracket from a single piece of material, the bracket including the latch element above referred to.

The nature and advantages of the invention will be better understood when the following detailed description is taken in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application like numerals of reference indicate similar pants in the several views, and wherein Figure 1 is a front elevation showing the manner of mounting the window shade roller on a window frame.

Figur 2 is a perspective view of one end of the window shade roller showing the manner in which the grooved member is associated therewith.

Figure 3 is a sectional view taken through Figure 2.

Figure 4: is a! perspective view of the window shade bracket above referred to.

Referring to the drawings in detail, 10 indicates a window shade roller of well known construction, except that this roller Serial No. 645,381.

is not provided with the usual ball and ratchet mechanism generally employed to hold the shade in a given position against the tension of the spring 10 forming part of the roller. In place of the mechanism just mentioned, I mak use of a groowed member 12 provided with a threaded element 13 so that the member 12 can be screwed into one end of the roller 10 in the manner illustrated. It is of course to be understood that this is the preferred embodiment of the invention and that the grooved member may be associated with the roller in any other suitable manner. The groove member can also be constructed of wood, the disk 14: associated therewith is preferably constructed of metal. This disk is provided with a depression 15 for a purpose to be presently described. The roller 10 is mounted upon the window frame in the usual manner, but in accordance with the present invention one of the window shade brackets is of novel construction.

This bracket is formed from a single piece of material and includes a body portion 16 provided with the usual slot 17, and an attaching portion 18, by means of which the bracket is secured to the window frame. The bracket further includes what I term a latch element 19 which projects from the body of the bracket and is arranged in juxta-position to the disk 14:. The latch element possesses the necessary degree of resiliency to permit of its operation in a manner to be presently set forth, and this resiliency is provided by the inherent quality of the material from which the bracket is formed. The latch element 19 is provided with a pin 19 which projects from one side of the latch element and is adapted to be received by the depression 15 of the disk 14 for holding the shade in a given position. The flexible element 21 is terminally secured to the latch element 19 and suspended therefrom in convenient reach of the user.

A cord 20 is adapted to be wound about the grooved member 11 and unwound therefrom, and when unwound, rotates the roller in order to roll the shade against the tension of the spring. In practice, the flexible element 21 is held in one hand, and used to hold the latch element 1.9 slightly spaced from the disk 14:, while the cord above referred to is unwound from the grooved member for the purpose of rolling the shade. The shade may be arranged in any desired position, and held in this position by releasing tlie flexible element 21, which allows the latch element 19 to associate itself with the disk 14 in a manner described in order to hold the shade in the position mentioned. In order to raise the shade, it is only necessary to separate the latch element from the disk by pulling upon the flexible element 21, whereupon the spring of the roller 10 will rewind the shade as will be readily understood. By holding the cord 21 during this operation it will be manifest that the shade can be elevated gradually.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it known that I do not limit -myselt to What is herein shown and de scribed and that such changes may be resorted to as fall Within the scope of what is clalmed.

What I claim is:

The combination with a window shade roller, of a grooved member attached to one end thereof, and having a depression at one side, acord adapted to be wound about said member and unwound therefrom to roll the shade against the tension ol? the spring of said roller, a bracket formed from a single length of material into substantially L- shaped formation, and including a lixed limb and a relatively mo 'able resilient limb. means for securing the bracket to the window casing, a pin projecting from said movable limb and adapted to normally project within said depression to hold the roller stationary, and a flexible element suspended from said movable limb and utilized to separate the pin from said depression to permit rotation of the roller.

In testimony whereof I aflix my signature.

JOHN P. HALL
