' WINDOW-SCREEN.

- Specification of Letters Patent.

Patented March 2, 1909.

Application filed September 14, 190;. Serial No. 453,038.

screens for a window made of material sufficiently flexible to be wound on a roller or rollers concealed in a boxing at the bottom or top of a window frame, or both, and having one end of the screen secured to a window sash to be unrolled when the window is opened and rerolled by simple means when the window is closed so that the screen shall be hidden from view.

With these and other objects in view the invention consists of the novel construction, combination and arrangement of parts hereinafter described and claimed and illustrated in the accompanying drawings, in which Figure 1 is a View of a window from within, the window frame being shownin section. Fig. 2 a vertical sectional view on the line 22 'throughthe side of the frame dis- A line 44 of Fig. 1.

closing the cords and weights; Fig.3 a detail view in section on the line 33 of Fig. 1, and Fig. 4a crosssectional view on the Like reference characters are used same parts inall the figures.

'In the drawing, the window frame A has the usual boxing 1 at the sides for containing the sash cordsand weights that balance the upper and lower sash 2 and 3 respectively. Besides the side lboxings 1 there is a boxing 4 at the bottom of the window frame and one 5 at the to thereof, the two :boxes extending across said window frame and opening into the side boxin'gs. Within the bottom boxing 4 is placed a horizontal roller 6 having end pintles 7 which fit into and rotate in bearin 8 fastened to the outside boards 9 of the frame A. A similar rollerlO is pivotally supported in the upper boxing 5 as shown. The two rollers 6 and 10 are nearly as long as the width of the window frame between the outside boards 9 for'the is wound a cord 12, one end of which is fastened to the roller and the opposite end to a weight 13. F astened to the lower roller 6 and woun thereon is a sheet of screen material 14 such as wire cloth, as wide as the lower sash 3 and long enough to close the opening caused by raisin the sash as high as possible. The upper en of the screen 14 is fastened to the outer side of a bar 15 which latter is fastened to the bottom rail 16 of the lower sash by means hereinafter described. similar screen 17 is mounted on the upper roller 10 and fastened at its lower end on a bar 15 reinovably attached to the top rail of the upper sash by means similar to that used for fastening the screen 14 to the lower sash.

The object of the weighted cords 12 is to keep the screens stretched when in use and to wind them onthe rollers while closing the window sash 2 and 3. The weighted cords on theupper roller 5 hang straight down therefrom-and when the upper sash' 2 is lowered, the screen is drawn from the roller which is rotated in direction to wind the cord thereon, then, when the sash. is raised, the weights 13 cause the cords to rotate the roller in opposite direction and thescreen is in turn wound on the roller. The bottom screen 14 is unwound and wound on its roller 6 in the same manner as the upper screen 17 on its rollers 5, but to get suflicient length of movement, the cords 1 2 which pass around the bottom. roller are each carried up a trunk 1 nearly to the top and after passing over a pulley 18 aweight' 13 is fastened to the end of each cord.

As heretofore stated, the bottom screen is fastened to a bar or rod 15 which in turn is removably attached to the bottom rail of the lower sash.' Thisattachingmeans is illus trated in Fig. 1 and more clearly in Fig. 3

where may be seen a circular plate 20 hinged below to a plate or hinge butt 21' secured on the inside of the bar 15 so that the axis of the hinge shall be above or on a line with the top of the bar that it may be swung downward away from the sash rail. Rota-'- and its finger are turned, forms a part of the stem, but lies onthe opposite side of the circular plate.

Seated in around opening in the bottom rail of the lower sash 3 is a cylindrical socket 25, flanged on its outer edge to bear against the face of the sash rail and having a perforation 26 in its bottom for the stem and finger topass through. The number of attaching devices employed will depend upon the width of the window and other circumstances, two being shown in the drawing, one at each end of the bar 15.

The screen is fastened to the lower sash by placing the bar 15 in position, then turning the plate 22 into the socket 25, which is cut away for the purpose, until the finger 23 passes through the opening 26 therein, when a turn 'of the thumb piece w1ll be sufficient to fasten the parts together. Precisely the same attaching means are used for fastening the bar 15 to the upper sash as are used for securing the bar or red 15 on the lower sash. The bar 15" however is larger'and lies on top of the upper sash and has the hinge butts 21 secured to the inner. face thereof.

The plates 20 hinged to said butts project downwardly to enter the sockets 25 in the top rail of the upper sash.

What is claimed is The combination with a window frame, and a window sash having a recess in one of its rails, of a roller mounted in the window frame opposite the aforesaid sash rail, a screen fastened at one end to said roller and wound thereon, a bar extending across and secured to the other end of the screen, said bar fitting the aforesaid sash rail, a member hinged to the bar and carrying a turn button having alaterally projecting finger, and a plate seated in the recess of the sash rail, and having a slot to receive the shank of the turn button, the finger of the said turn button engaging behind the plate.

in testimony that I claim the foregoing as my own, I have hereto afiiXed my signature in the presence of two witnesses.

WILLIAM FREDERICK GIBBARD.
