WINDOWfSCREEN ROLLER.

SPECIFICATION forming part of Letters Patent No. 311,044, dated January 20, 1885.

Application filed July .25, [834.

T0 ail whmn, it may concern..-

Be it known that I, SIMEoN U. TARNEY, a citizen of the United States, residing at Auburn, in the county of De Kalb and State of Indiana, have invented certain new and useful Improvements in Window-Screen Rollers, of which the following is a specification,reference being had therein to the accompanying drawings.

The object of my invention is to provide a window-screen roller which can be readily attached by any person to windows of different widths, convenient to put in or take out at pleasure, can be rigidly kept in place, the screen can be drawn or stretched perfectly taut and smooth at both edges and the center, can be compactly packed, without taking to pieces, when temporarily out of use, or for storing or shipping, and durable and economical. These objects I attain by means of a concave roller having a groove, a tightening or stretching device connected with a wooden strip by metallic angle-shaped metal attachments having beveled vertical slots for ready adjustment at one side of the window-frame, and a wooden strip having metallic attach ment-pieces provided with angular slots and flat ears for ready and perfect attachment to the other side of the window-frame.

In the accompanying drawings, which form a part of this specification, Figure l is a front elevation showing my inventionwith screen attached as applied; Fig. 2, a detail detached view of the upper end of the concave roller, showing the groove, the tightening device, and strip for attachment to one side of the window-frame, and the upperend showing one metal attachment-piece with angular slot and flat ear of the strip for attachment to the other side; Fig. 3, a plan View of the tightening device; and Fig. 4, a detail section through line w as, Fig. 3, showing the beveled vertical slot. Y

Similar letters of reference indicate like parts.

A A represent the window-frame; a a, the strips that hold the screen B in position 5 0, the concave roller, having parallel groove 0,- D, the top ratchet-gear; d, the hand-lever, with projection d, by which to engage with the teeth of the top ratchet-gear to turn the (X0 model.)

concave roller in order to stretch the screen, which is retained in its place by the pawl E. A metal attachment-piece, F, of angular shape, provided with a shoulder, to which the pawl E is loosely riveted at r, and having a beveled vertical slot, f, is rigidly secured to the side of the wooden strip a near the top, by means of common wood-screws. A similar metal attachment-piece, but without ashoulder, is in like manner secured to the side of said strip, near the other end. The top ratchet-gear, l), is rigidly secured to the top end of the concave roller 0 by means of common woodscrews, and it is provided with ahub, h, which is employed to hold the concave rollerin place by passing it through a hole in the metal attachment-piece F, and it further serves as means for securing the hand-1ever d, to which it is loosely fitted and retained in its proper place by pin 19. The lower end of the concave roller 0 rests on the lower metal attachment, as shown in Fig. 1. ment, G, having an angular slot, 9, anda fiat ear, is rigidly secured by common woodscrews on the edge, near the top end, of strip a. A similar metal attachment is secured in like manner on the edge near the lower end. (N 0t specially shown in drawings.) Pawl E is provided with a projection, E, back of rivet r, for the purpose of enabling aperson with one hand to disengage the pawl from the ratchet when desired.

In order to take the screen from the window,the ratchet must be turned a little to the right by lever d, and at the same time bypressing on the projection E with thumb or finger the pawl is liberated and thrown to a vertical position, where it remains until the screen is removed from the window, the weight of the projection E being sufficient to balance or retain it in said vertical position.

In applying my invention netting or screen cloth of any material, either of fabric or metal, may be taken and cut to about the desired length, one end of which is then tacked onto the flat side of the strip a, and the other end to the parallel angular bevelcin the concave roller 0. Two common wood-screws are driveninto either side of awindow-frame until their heads protrude about half an inch. The roller attachments and screen are taken up, the open- A metal attach-- ing of the angular slot is slipped in by the The strip a is now placed on the screws in the other side of the window-frame by means of the hole 0, and slightly forced down. The heads of the screws snugly fitting the beveled vertical slotsf, that part is firmly secured in place. The screen-cloth now hangs loose, but by pulling the hand-lever. d toward you the concave roller is turned, the screen cloth wound around it, and all the slack taken up and held by the pawl E, which drops in and engages with the teeth on the top ratchet-gear, D, thus preventing the screen from u n rolling when the hand-lever is released. Vhen the screen is not needed in the window, it can be taken out by first disengagingthe pawl, which loosens the screeircloth, and then by lilting up the strips, which releases them from the screw-heads in-the window-frames.

There being no frame to the top or bottom of the screen, when my invention is used, it can be seen that the whole appliance can be rolled into a very small compass.

\Vith my concave roller one is enabled to stretch the screen-cloth at both edges and the center and have all taut, and, so far as I have been able to learn, this is the only roller that will stretch a screen so that it will not sag in the center or at the edges within a short time, and by having the groove the screencloth is fitted to the concave roller in such a manner that it rolls up perfectly smooth.

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

1. The combination of the strip a, the screen, the concave roller 0, having ratchet D, hearing F, and pawl, substantially as described.

2. The screen and roller, the. lever cl, having a lip or projection, d, in combination with ratchet D, bearing F, having shoulder at right angles to its main portion, the pawl E, having the projection 15, pivoted to said shoulder, and the hub h, substantially as described.

3. The combination of the concave roller C, the lever (I, provided with a catching projection, d, integral therewith, the ratchet D,

pawl E, having the projection E, and hub h, substantially as described and specified, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

SIMEON U. TARNEY.
