WINDOW-SCREEN.

Specification of Letters Patent.

Patented May 2, 1916.

Application filed May 17, 1915. Serial No. 28,709.

to the class of automatically rotatable screens.

The primary object of the invention is the provision of a screen to be used in connection with the lower sash of a window, which is capable of being stored away when not required foruse, which is automatic in its operation, and in which a durable, efficient, and economical device is provided for the purposes designed.

The invention consists in certain novel combinations and arrangements of parts whereby the screen isattached to and automatically rotatable with the movement of the lower sash of the window, as will be hereinafter more fully pointed out.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of the invention.

Figure 1 is an frame and two window sashes, the lower of which is elevated showing the screen in use. Fig. 2 is an enlarged end view of the screen attachment showing one end of a'window sill, in order to illustrate the application of the invention. Fig. 3 is a view showing one end of the rolled window screen, and the releasing device for the screen. Fig. 4 is a view showing the automatic rotatable roller for the window screen, and the release device, parts being shown in section. Fig. 5 illustrates the lower bar of the lower window sash, and shows one of the lifts or lifting plates to which the window screen is detachably fixed.

As an exemplification of my invention I have utilized a standard window construction involving the usual frame 1 and the sill 2, and the window sashes 3 and 4.; are of the usual balanced weight sashes, and these sashes of course are adapted to be moved in their usual-runways in the frame.

The window screen is designed to be inelevation view showing the closed within a housing 5 which is located upon the window sill 2 inside of the room, and at either side of the window frame a strip 6 is hinged at 7 to the frame in order to close the spaces .at the ends of the lower sash 4 when said sash is elevated.

Preferably, the lower bar 8 of the lower sash is utilized for suspendingthe screen, and for this purpose the lift lates 9 which are of the usual type employe for grasping by the fingers when the lower sash is to be lifted, are secured to the cross bar 8 and are utilized as the suspending means for the screen. The housing 5 is made up of two wooden strips arranged at right angles with the open portion of the housing toward the window, and brackets 10 and 10' are employed by means of which the housing is secured to the frame. and to the window sill respectively.

The screen 11 is made up of any suitable fabric, and at its end is provided with a metallic strip or plate 12 while its edges are fashioned with suitable devices or means to prevent unraveling. This plate 12 is fashioned with a suitable number of openings 13, and in Fig. 5 particularly it will be seen that these openings are the means ofsuspending the screen over hooks 14 formed integral with and struck from the body of the lift plates 9 on the bar 8 of the lower sash 4-. By this means the screen is detachably fixed to the window sash, and it will be seen that the screen may be quickly attached or detached if itis desired to remove the screen from the window. If it is desired to detach the screen from the window, the screen is automatically wound inside its housing, and the screen is hooked or temporarily attached to the housing by utilizing the two knobs or buttons 1.5 on the strip 12, which are adapted to fit into the slots 16 in the top plate of the housing, as best seen in Fig. 3.

The screen is automatically wound on roller 17 in manner similar. to the usual automatic rotatable window shade or curtain.

This roller 17 is provided with the usual usual type for automatic Window shades,

and has afiixed thereto a clutch member 23 which is adapted to co-act with another' clutch member 24 carried by the revoluble roller 17, and to this clutch member 24 the spring 17 which is inclosed within the 21 is attached to a release lever 26 which is provided with a handle 27, and the fulcrum of this lever is the edge 28 which is adapted to bear against the bracket 20. Thus, in Fig. 4 it will be seen that when the handle 27 is swung to the left the spring rod 21 through its connection 25 to the lever will be drawn to the left, the point 28 being the fulcrum of the lever, and as the spring rod is drawn to the left it carries with it the clutch member 23 which is thus disengaged from the member 24, and then the spring 17 automatically winds the roller. tween the clutch member 23 and the bracket 20 a spring 29 is located, and the function of this spring of course is to keep the clutch members in engagement unless pulled apart by the action of the lever 26. The top board of the strip of the housing is slotted at one end, as indicated at 30 for the accommodation of the handle 27 of the lever 26. Thus, with the strip 12 attached tothe hooks 14, when it is desired to raise the window, it is preferable to swing the lever 27 to the right in Fig. 1 to disengage the clutch members 23 and 24. When these clutch members are so disengaged, the lower window sash may be elevated as usual, and the screen is raised with the sash, it being unrolled from the roller 17 against the tension of the spring 17. The window, of course, is of suflicientIweight to hold the screen ll'in position as shown in Fig. 1, but the lever 26 when freed, permits the spring 29 to close the clutch 23-24, and movement of the roller is prevented, and the strain is takenpfl of the spring, but it will be seen that the screen 11 is held taut and prevented from wrinkling or bulging,

and is made to present a neat and workmanlike appearance. lower the window, the-lever 27 is pressed to the right in Fig. 1 to rel'ease the automatic winding roller, and then when the window sash is lowered the screen is automatically wound inside its housing, and is thus moved out of the way of the descending window. When the screen is not to be used or is to be stored away permanently, the perforated plate 12 is disengaged from the hooks 14 and then the knobs 15 are caught in the notches 16 of the housing, and the screen is thus inclosed within the housing as shown in Figs. 2 and 3.

From the above description taken in connection with my drawings, it is evident that I have provided a device which is facile and efficient in operation, is durable and will perform its functions in a workmanlike manner..

What I claim is:

1. The combination ina window sash attachment, of a housing, an automatically revoluble roller supported in the housing and a screen wound upon the roller adapted for attachment to the sash, a spring rod movably supported in the roller, a pair of supporting brackets for the roller and rod, a clutch member on the roller and a similar member-on the rod, and a lever pivoted to the rod with its fulcrum on one of the brackets for disengaging the clutch members.

2. The combination in a window sash attachment, of a housing with supporting brackets, an automatically rotatable roller and a spring rod supported in the brackets, and means to normally prevent rotation of the roller. a screen Wound upon said roller and attached to the window sash,and a lever pivoted to the rod and adapted to fulcrum, on a bracket when rocked on its pivot to open the clutch members.

In testimony whereof I affix my signature.
