SHADE OR CURTAI1\T ROLLER.

Specification ofLetters Patent No. 32,034, dated April 9, 1861.

To all whom t may concern: y

Be it known that I, LANGDON SAWYER, of Springfield, in the county of lindsor and State of Vermont, have invented a new and Improved Roller for VVindow-Shades, Netting, &c.; and I do hereby declare that the l t direction. This roller D, hasA lts pivot bearfollowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1, is a view of the inside of a window having my improved roller applied to it, for operating a mosquito net which is applied to the lowerwindow sash. Fig. 2, is a transverse section through Fig. l, in the vertical plane indicated by red line ac, a', thereon. Fig. 3, is an enlarged exterior view of the improved roller. Fig. 4e, is a longitudinal section through Fig. 3 in the red line y, y.

Similar letters of reference indica-te corresponding parts in the several figures.

The object of this invention is to so construct the bar, under which the netting or shade passes from a, spring roller which winds up the shade, or netting, as the case 'may be, that the whole fixture may be applied to window frames varying'in widths and secured therein with very little labor, without employing the usual fixtu'res which are secured to and which mutilate the casing of the window.

The nat-ure of my invention consists in making said rod, under which the netting or shade passes, adjustable longitudinally, and in securing to the `ends of this rod the plates or brackets, on which the spring roller has its bearings, as will be hereinafter described, whereby the roller and bearing plates may be extended and thus adapted to, and secured within any ordinary window frame in a substantial manner.,

To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the accompanying drawings: A, rep` resents an ordinary window casing, or frame within which the window sashes B, and C, slide up and down either by weights and pulleys or in any other suitable manner. To this window frame A, with its sashes my invention is to be applied.

D, represents a roller having a cylindrical barrel a, on one end which contains a common clock spring which being attached to tion indicated by the arrows in Figs. 1 and 2 of the drawings, and which recoils when the roller 1s allowed to rotate in an .opposite ings in two end plates E, E, as shown in Figs. 1 and 2 of the drawings, which plates, or bearing blocks, are attached to the roller.

Extending across from plate E, to plate E, and parallelwith roller D, is a round rod G, as shown in Figs. 1, 2, 3, and 4 of the drawings, which may be secured. rigidly at its ends to the plates E, E, or so attached to these plates as to rotate and form a friction roller. The object of using this rod G, hitherto has been to keep the shade, or more particularly mosquito netting down close to the window sill so as to prevent insects from crawling under the netting, but with my improvement applied to the rod G, it also serves another equally important office, which will be hereinafter explained. On one end of rod G, a metal ferrule b, is secured having a hole through its axis in which a female screw thread is cut as shown in the enlarged view, Fig. 3. The screw c, which passes in the hole in' ferrule Z9, is of a considerable length as shown in Fig. 3, and this screw is secured to the inside of one of the plates E, E. Surrounding screw c, and concentric with its axis is a metal tube, or socket d, which in its exterior diameter is equal to the diameter of the rod G, so that the whole will lit together and appear as one bar. The socket d, is as long as the screw stem c, and the end ofthe ferrule ts into the socket (Z the socket being secured to the plate E. Thus it will be seen that by unscrewing the rod G, from the socket, the plates E, E, will be separated farther apart, and by screwing up the rod G, the plates E, E, will approach each other until the end of socket al, comes in contact with the shoulder onthe ferrule The opposite end of the roller D, to that carrying the spring box a, has a hole bored in its center the same length o-f the screw stem Z9, on the plate E, and into this holeh a pin which projects from plate E, passes so that the roller will turn on this pin.

The shade or mosquito net e, is tacked to the roller D, and passes under the extension rod G, and issecured to the lower rail of the lower Window sash B, by hooks and eyes or any other suitable device, so that when the sash B, is raised, the shade, or mosquito net, Whichever be used, will be drawn up and unWound from roller D. When the Window is depressed the spring in roller D, will cause this roller to Wind up the netting again.

Now from the `foregoing description it Will be seen that by means of the extension rod G, the plates E, E, may be extended or contracted and the lixtures may be clamped securely within any ordinary sized Window casing Without nails or screws, brackets, or the bearing plates, &c., Which have been heretofore employed, which injure the appearance of the Window frame and require the rollers to be especially adapted to them, as Well as to the Window for Which they are to be used. With my extension rod the Whole vshade 0r netting can be readily ap- I plied to a Window and removed in a few minutes.

This extension rod hereinabove described, may be applied with great advantage to ordinary shade fixtures Where a common roller to which the shade is attached, is used instead of the spring roller.

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

Making the rod, or roller G, so that it can be extended or contracted longitudinally, where the same s combined With the other fixtures for operating the shade or netting, substantially as and for the purposes herein described.
