WINDOW-SCREEN.

Specification of Letters Patent.

Patented May 19, 1914.

Application filed June 21; 1913. Serial No. 775,157.

To all whom it may concern:

Be it known that I ALICE E. PADDISON, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Window- Screens, of which the following is a specification.

My invention relates to window screens and has for its object to provide a device whereby screens may be fastened to andwound on rollers and detachably hooked to each window sash, which rollers are automatically wound and unwound as the sashes are raised and lowered.

The screens and the devices operate and are arranged to keep insects and small particles of any kind from getting'into a room and are so arranged that when the sashes are in their normal position and the screens detached therefrom the screens are wound on their respective rollers and out of sight.

The devices are so constructed that the screens and rollers may be removed at any time to be rep-aired or replaced.

These objects I have accomplished with device illustrated in the accompanying drawings, in which similar letters of reference indicate like parts throughout the several figures, and as described in the specification forming a part of this application and pointed out in the appended claims.

In the drawings embodying my invention, Figure 1 is an enlarged vertical sectional view through the lower portion of a window with a part of the lower sash shown and the screen attached thereto and unwound. Fig.

2 is a vertical sectional view through the window, parts being cut away, showing the upper sash with the screen hooked thereto and wound on the roller; and showing the lower sash partially raised with the screen detached therefrom and wound on its roller. Fig. 3 is a view in perspective of the lower sash of a window looking from. the room outwardly. Fig. 4 is a fragmentary view of one of the guide strips. Fig. 5 is a detail view in. perspective of one portion of the roller holding frames. Fig. 6 is a view in perspective of a part of another portion of the roller holding frame, before the same is bent into form. Fig. 7 is a fragmentary view of one of the roller holding frames for the upper screen assembled. Fig. .8 is a fragmentary view in perspective of the roller. frame for the lower sash before it is in section.

bent into shape. The dotted lines show where the same may be bent to fit windows of different widths. Fig. 9 is a View of same after it is bent into form. Fig. 10 is a fragmentary view in perspective showing one end of the binding plate, guide plate and hook plate. Fig. 11 is a View in elevation, diminished, of one of the roller frames, with one of the rollers and screen thereon shown Fig. 12 is a modified form of the llginding plate, hook plate and guide memers.

In the construction and use of the window screen patented by me on June 7, 1910, Number 960388, I have observed that the edges of the screen are liable to be displaced when the window is open to such an extent that insects may enter around the edge of the screen, and I have shown in this device a means of overcoming such defect; also I have observed that to secure this screen quickly and economically to the hook plate, and in such form that it will readily engage the sash hook that some re-inforcement is needed on the edge of the screen. I have overcome such defects and show in the drawings a substantial embodiment of my invention and device therefor in connection with my former patented window screen.

Referring now more particularly to the drawings, I have shown at the numeral 1' the front frame of the window casings; 2 the rear frame; 3 the upper sash; 4 the lower sash; 5 the upper screen; 6 the lower screen; 7 the glass in the upper sash; 8 the glass in the lower sash. The sashes are constructed as ordinary sashes, except that a portion of the vertical part of each sash is cut away as at 19 to provide an angled recess in which a portion of the metalguide strip 9 is placed. Said portion shown at 11 is bent at right angles to the part having perforations 10 therein, by which the said guide strips are secured to the window casing.

The lower part of the window frame is provided throughout its width with a drain sill 15 and a front sill 16. Secured to the inner edge of the drain sill 15 is a perforated plate 21, having openings 29 therein by means of which it isheld in place and secured at the endof the guide strips 12 and the dividing strips 13 of the window casing. A portion of the sash of each window is cut away to receive a sash hook 25, which is fastened thereto within the said cut. A portion of each end of said plate 21 is bent at practically right angles to fit against the sides of the window frame, to form bearing 26' for the lower roller. Said portions 26 have perforations therein those on one end being rectangular slots and those at the other end circular holes, and when bent into form, as shown in Fig. 11, a screen roller 30 is carried therein. The roller holder frame for the upper sash has portions of the plate 22 secured within plates 17 and bent at right angles to form the bearings for the upper roller. Said holder is fastened in place by screws through said portion 17. Each of said rollers 30 consists of a hollow Wooden cylinder having perforated disks 31 secured thereto, and inserted through central openings in said disks is an axle 34, the ends of which extend into the openings 27 above mentioned. One end of said axle is flattened to engage in said elongated perforation 27 and said axle is thereby kept from revolving. A spiral spring 35 has one end secured to said axle 34 and the other end in one of said disks 31 for the purpose of rotating said roller when the spring is under tQlSlOIl.

A wire screen of the width of the window sash has one end thereof held between a metal ends laterally extended as at 12 to form guide lugs which are made to operate in a channel ormed with the recess cut 19 as one wall and bottom and said portion 11 of the guide strip 9, as the other wall. Said guidev plate 40 is bent to form' a sash engaging hook 41, which may be engaged with said sash hook 25 to lock the screen and sash together. When said hooks 25 and 41 are not engaged the'said spring 35 will roll the screen on the roller 30 and the stop member 43 will close the opening between the

plates

21 or 22 and the sill 16. Another way of forming the binding plate and attaching the screen thereto is shown in Fig. 12 wherein the plate 39 is bent to form a channel 44: within which the plate 37 and the end portion of the screen after it is bent around the plate 37 is inserted. This form of making the binding plate and manner of connecting the screen and sash may be used if desired. The-screen roller 30, screen 5 with means for fastening the screen to the roller, the binding plate 39, hook plate 40, hook 41, guide lug 42 and a plate 22 are secured in the upper part of the frameand are similar .to and are used for thesame purposes as those described for the lower sash.

The use of my device is as follows: The roller frames are secured in place and the rollers mounted therein. secured to the binding plates by rivets or short screws through the

plates

37 and 39. When the sashes 7 and 8 are lowered and raised into position the sash hooks 25 will automatically engage the hooks 41 and the

screens

5 and 6 are then in position for use. When the window is raised the screens will prevent insects from passing into the room.

Having described my invention, I desire to secure by Letters Patent and claim:

1. In a device of the class described the combination of a frame carrying a co-acting upper and lower sash having a recess cut in the outer edge of each of said sashes contiguous with said frame; a guide strip fastened on the sides of said frame which partially fills said recess; a metal plate fastened Within the upper end of said frame, another metal plate fastened within the lower end of said frame having its end portions bent to form roller bearings; a spring actuated roller mounted in said bearings; a spring carried in said roller; a flexible metal screen having one end fastened on said roller; a metal strip secured to the other end of said screen having a flange and a hook plate and with a portion of each end extended to operate between said guide stri and a portion of said frame; and a sas hook plate adapted to engage with said.

The screens are' with said binding plates adapted to operate within said channels of said guide strips; and a sash-hook-plate on the lower sash adapted to engage with said hook plate on the lower screen by lowering; and a sashhook-plate on the upper sash adapted to engage wit-h the hook plate on the upper screen by raising said upper sash" 3. In a device of the class described the combination with the window frame, of sashes operable in said frame and having recesses cut in the edges thereof contiguous said frame; guide strips fastened to the sides of and withm said frame to form vertical channels, metal plates fastened within the upper'and lower ends of said frame; roller bearings on the end portions thereof; springactuated rollers mounted in said bearings;

flexible screens fastened on said rollers; a

nels; and a hook plate on each sash adapted to automatically engage said hook member. 4.1m a device of the class described the combination with the window frame; of-
