SHADE-ROLLER. 7

Specification of Letters Patent.

Patented Feb. 25,1913,

Application filed November 25, 1911, Seria1N0.'662,353. Renewed January 20, 1913. Serial No. 743,207.

To allwhom it may concern:

Be it known that I, Gnonon B. (Shares, a citizen of the United States, and a resident of Coffeyville, in the county of Montgomery and State of Kansas, have invented a new and Improved Shade-Roller, of which the following is a full, clear, and exact description.

My invention relates to a new and improved form of shade holder.

It is well known that in order to put up the form of shade rollers now on the market, it is necessary to placebrackets at both ends of the framework of a window, which requires nailing or screwing to support them, thereby defacing the framework and causing a great deal of annoyance and inconvenience in placing the shades 'in position, and in adapting the shades to fit different sized windows. Further, with the shades now in common use, it is very inconvenient to lower the window from the top, as the draft causes the shade to rustle, and if the fit is at all tight, it is almost impossible to ventilate the room by this means.

An object of my invention is to eliminate these objections, by construct-ing a. shadewhich may be accurately and readily adj usted in place without the use of any screws or nails or any other attachments.

A further object of my invention is to so construct and arrange the shade that it may be placed at any position on the frame work of the window, so as not to interfere with the opening of the window for ventilation or other purposes.

A further object of my invention is to so construct the shade roller that it may be attached to any sized window and may be afiixed to the framework irrespective of the material of which it is constructed.

With the above and other objects in view, as will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

I attain the above outlined objects by journaling within the shade roller, a rod composed of two telescoping parts, one of said parts having an external means for changing the length of said rod to fit dlfferent sized window openings, the outer ends of the rod parts terminating in spring vation; Fig. 3 is an end view looking at the right of the device shown in Fig. 2 but mounted upon a bracket, and Fig. 4 is a transverse sectional view taken on the line 4t of Fig. 2 and looking in the direction of the arrow.

In the several figures, I have shown up rights 1 of the framework 2 of the ordinary form of window. Positioned at any desired point between the uprights, is theimproved shade roller forming the subject-matter of my invention. This shade roller comprises a cylindrical tube 3, about which is wrapped, in any suitable manner, the curtain 4:- The tube 3 is closed at each end by means of closing caps 5, which afford a bearing for the axially disposed rod 6. This rod comprises two telescoping parts, one part 7 extending beyond the adjacent end of the tube, having rigidly fastened thereto, an archshaped spring plate 8, the opposite end of which part 7 is screw-threaded and engages within the screw-threaded end 9 of the coacting hollow part 10 of the rod 6. This part 10 is loosely in engagement with a spring plate 11 corresponding in structure and thickness to the plate 8.

In order to rotate the part 10 relative to the part 7 0f the rod 6, the outer end of the part 10 terminates in a square head 12, which square head is engaged by a hand wheel 13 having notches 14: in the periphery thereof, by means of which notches the wheel may be rotated so as to vary the length of the rod 6, to fit any desired window opening.

In order to hold the tube resiliently in engagement with the rod 7, a coil spring 15 encircles the part 7 of the rod 6, and has one end in engagement with the diametrically extending fingerslG projecting from a plate 17, which plate is loosely mounted on the part 7 but rigidly connected to the adjacent closing cap 5. The opposite end bracket engages a socket 20 carried by the plates 8 and 11.

The roller is disposed between the uprights with the rod 7 held by gripping the body of the shade and rotating the wheel with its attached tube 10 until the spring plates 8 and 13 are in firm engagement with their adjacent uprights.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. The combination of a cylindrical tube adapted to carry a curtain, a two-part rod within said tube and rotatably supporting the same, an arch spring plate fastened centrally to each end of said rod adapted to Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

tube having a spring fastening plate on one end thereof and a square head adjacent said plate, a rod in threaded engagement with said tube, said rod having a fastening plate pivoted to its outer end, and a hand wheel mounted on said square head to rotate said tube relative to said rod, thereby to cause said plate to engage a support and a roller loosely mounted on said tube and rod.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
