WINDOW-SCREEN.

SPECIFICATION forming; part of Letters Patent No. 394,236, dated December 11, 1888.

Application filed April 9, 1888.

To all 1072 0111 it may conccrn' Be it kn own that we, GEORGE \YILLARD an d LEWIs TAYLOR \VILsON, eiti zens of the United States, residing at Pasadena, in the county of Los Angeles, State of California, have invented a new and useful Im n-ovement in \Vindow-Screens,of which the following is a s 'iecification.

()ur invention relates to that class of wiregauze window-sereens in which the screen is adapted to be rolled up and down like a cur tain; and it comprises cheap and simple means for preventing an y side openings, and for holding the screen taut and preventing it from being witlnlrawn from the frame, and at the same time allow it to slip up and down freely.

The drawings illustrate our invention.

Figure l. is a perspective view of the inside of a window provided with our improved screen as it appears when in use. Fig. 2 is a vertical section on line X X, Fig.1. Fig. 3 is a cross-section on lineY Y, Fig. 1. Fig. l is a. longitudinal section of the roller with the operating-spring and its mountings shown in full. Fig. 5 is a longitudinal section of the roller-mountings with the springattachment, parts being broken away. Fig. h is a detail in crosssection illustratingthemannerof securing the gauze in the grooves. Fig. 7 is a perspective view illustrating the front of the bent stiffening and guide bar 1, showing the dent ll. Fig. 8 showsthe stiffening-lair woven into the wire. Fig. 9 is a detail showing the lower end of the screen.

The free spring-actuated roller 13, having no catches cminected therewith, is mounted in the rollei'-supporting brackets N at the top of the wiildmv-easing, and. the sheet of wiregauze A is attached thereto by one end. The spring C is attached to the roller and the bracket, so that its recoil tends continually to turn the roller to wind the gauze thereon, so that when the gauze is free the spring wraps it upon the roller, and as the gauze drawn down the tension of the spring becomes greater, thus drawing the gauze perfectlv tight when it is fastened down, as shown in Fig. l.

The edges of the gauze are not bound, but the bottom of the screen is clamped between Serial No. 270,122. (No model.)

the bar D and the thin metal strip E, the ends l of which run in the grooves ll formed by rabbets H H, made in the side of the strips F E, which are secured to the face of the casings, and are rabbeted and grooved on the face next to the casing, as shown in l ig. (i, so that a groove to receive the edges of the gauze and the ends of the strips which hold the gauze in the grooves is "formed by the rabbctbetween the casing and the strip F when the strip is in place. Therabbets and the grooves they form are both referred to by the. letter Ii, as the are identical.

In order to secure the gauze from being witlnlrawn from the frame, and yet allow it to slip up and down freely, we secure to the gauze, near the middle thereof, in the ordinary manner, a thin rigid stilii'ening-bar extending entirely across and projecting beyond the edges of the sheet of gauze on each side 1 thereof, and having the projecting edges bent at right angles and indented at the point to give the inner face of the bent portion which fits against the side of the groove (l a rounded form, so that the edges of the bent ends of the bar will not cut into the walls of the groove when the screen is run up and down.

\Ve provide a case, M, for the roller at the top of the window.

The operation of the screen is obvious. \Vhen it is desired to raise or lower a sash, or to leave the view through the window wholl unobstructed, the bottom of the gauze is released and the spring is allowed to wrap the gauze upon the roller until the bar I) strikes the case M. \Vhen it isdesired to use the screen, thebar l) is drawn down and fastened, as shown. The metal bar l is preferabl v made of steel, and the bent ends prevent it from being withdrawn from the grooves, thus giving stability to the screen and locking it in the grooves, so that it cannot be pushed in or out at the middle. The wooden bar 'D on one side of the bottom of the gauze stit'fens the metal strip E, which is fastened thereto on the other side of the gauze, and fits between the strips l", which, in conjunction with the strip E, hold the bar in place, so that the screen cannot be pushed in or out at the bottom.

N are the brackets.

O is the casing of the window.

S is the rod to which one end of the spring 0 is attached. It is fixed to one of the brackets and is journaled in the roller. One end of the spring is attached thereto, and the other end of the spring is attached to the roller, which is devoid of catches and has one end journaled in the other bracket. The construction of the roller shown in the drawings is the same as that in common use in shaderollers.

\Ve are aware that wire-gauze screens secured upon spring-actuated rollers and having guide and stiffening rods secured to the gauze at intervals and extending thereacross to slide in grooves or suitable guideways to stiffen the gauze, have heretofore been used; but we are not aware that screens have heretofore been provided with a fiat narrow strip or bar extending across the gauze and projecting from the edges thereof, and having the projecting portion bent at right angles and provided with a dent, as L, to give its inner face a rounded form to fit against the side of a groove in the casing, as set forth, whereby we are enabled by cheap and simple means to firmly secure the gauze and hold it rigid, and at the same time allow it to be run up and down through the grooves with ease and without any liability of catching. 7

Now having described our invention, what we claim to be new, and desire to secure by Letters Patent, is V 1. I11 a window-screen substantially such as set forth, and in combination with rabbeted and grooved strips secured upon the face of the casings, the thin rigid metal bar secured to the gauze and extending thereacross, and having its ends bent at right angles to project into the grooves, and provided with a dent to give the inner face of the bent portion a rounded form.

2. The combination of the casing of the window, the rollersupporting brackets N, mounted at the top thereof, the free springactuated roller B, devoid of catches and having one end journaled in one of the brackets, the rod S, fixed to one of the brackets and journaled in the roller, the spring C, having one end attached thereto and the other end attached to the roller, the wire-gauze having one end attached to the roller, the strips F F, secured to the casing and provided with the grooves G and rabbets H on the face neXt to the casing, the bar I, having its ends bent and being provided with the dent L to give the inner face of the bent portion which fits against the side of the groove G a rounded form, the bar D on one side of the bottom of the gauze, the strip E, fastened thereto on the other side of the gauze, and means for securing the bottom of the screen to the sill of the window.

3. The combination of the free spring-actuated roller mounted at the top of the Window, the wire-gauze having one end attached to the roller, the casing of the window, the strip F, secured to the window-casing and provided with the grooves G and rabbets H 011 the face next the casing, the bar I, secured to and extending across the gauze at the middle thereof and having the bent ends J, provided with the dent L, and having its inner face rounded to fit against the side of the groove G, the bar D and metal strip E, fastened to the bottom of the gauze, and means for securing the bottom of the screen to the window-sill.
