WINDOW-SCREEN AND CONTROLLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 618,822, dated February 7, 1899. Application filed December 26, 1895. Renewed June 18, 1898. Serial No. 683,867. (No model.)

To aZZ whom it may concern/.-

Be it known that I, THOMAS E. BARR, a citizen of the United States, residing at the city of Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in WVindow- Screens and Apparatus for Controlling the Same,of which the following is a specification.

My invention relates to improvements in window-screens, and especially to improvements applicable to roller window-screens and controlling apparatus therefor.

The objects of this invention are, first, to provide improved means of attaching window-screens to a roller; second, to provide improved means of securing the windowscreen to the bottom of the sash; third, to provide improved means of controlling the attaching devices on the bottom of the window-sash; fourth, to provide an improved means of screening between the meeting-rails of the sash when the window is open, and further objects appearing definitely in the detailed description. I accomplish these objects of my invention by the devices and means described in the following specification and shown in the accompanying drawings, in which- Figure 1 is a front elevation of an entire window, showing my improved screen in place, portions of the casing and sash being broken away to show detailsof construction. Fig. 2 is an enlarged detail sectional view on line 2 2 of Fig. 1, the attaching-levers being shown in full lines and the operating-lever g for the cam in dotted lines. Fig. 3 is an enlarged detail perspective view of the pushbutton and means of adjusting the same. Fig. 4 is a bottom plan View of Fig. 3. Fig. 5 is an enlarged detail sectional view on line 17 17 of Fig. 2. Fig. 5 is an enlarged detail perspective lew 0? the gripping mechanism shown in Figs. 2 and 5. Fig. 6 is an enlarged detail sectional view on line 6 6 of Fig. 1. Fig. 7 is an enlarged detail View of one end of the roller, a art of the shell of the roller being broken away to show the attachment of the spring. Fig. Sis an enlarged detail sectional view on line 8 8 of Fig. 7. Fig. 9 is an enlarged deta l view on line 9 9 of Fig. 7. Fig. 10 is an enlarged detail sectional View on line 10 10 of Fig. 9. Fig. 11 is a sectional H, within the roll H.

View through the meeting-rails of the sash, showing a method of screening at that point. Fig. 12 is a View of my improved method of screening the window at the meeting-rails of the sash. Fig. 13'is an enlarged detail sectional View on line 13 13 of Fig. 12, showing the sash in the closed position. Fig. 14 is an enlarged detail perspective view of the lower corner of the upper sash shown in Figs. 12 and 13. Fig. 15 is an enlarged detail view of a slight modification of my improved device for attaching the screen to the roller. Fig. 16 is a view of a slightly-modified construction of the attaching mechanism of the sash to the screen below, taken on a line corresponding to line 2 2 of Fig.1. Fig. 17 is an enlarged detail sectional view on line 17 17 of Fig. 2. Fig. 18 is an enlarged detail sectional view of another modified form of the gripping mechanism between the sash and the screen,taken on a line corresponding to line 2 2 of Fig. 1. Fig. 19 is an enlarged detail sectional view on line 20 20 of Fig. 18.

In the drawings all of the section views are taken looking in the direction of the little arrows at the ends of the section-lines, and similar letters of reference refer to similar parts throughout the several views.

Referringto the lettered parts of the drawings, A represents the bottom rail of the sash; F, the window-frame; E, the windo w-sill.

Supported beneath the window-sill is the hollow roller H. This is borne on the spindle H, which is supported at each end by suitable brackets G on the frame G. The ends of the spindle H are squared and are inserted into square sockets in the bracket G. The hollow roller H is supported with solid ends, which arerevoluble on the spindle H. A coiled spring H is on the spindle The inner end of the spring H is secured to the spindle and the outer end is secured to the end of the roll H to put tension upon the roll when it is turned in either direction. On the end of the roll H is supported a dog I in position to engage upon a notch I, formed in the spindle, so that the roll can be wound up and locked against the spring after it is placed in position. On the outside of the roll H is hinged a strip of metal J at J, which conforms to the outer surface of the roll and bears teeth J on its free edge,

which pass through the screen and enter little apertures in the roll when the strip .I is closed against the same. The bottom edge of the netting or screen E is inserted between the strip J andthe roll II and is engaged by the teeth J automatically.

In Fig. 15 a modified method of hinging the strip is shown by pivots at the end.

The screen E projects up through a slot in the bottom of the sill. the screen is secured a strip of metal, which is folded into a tube D at the top, with outwardly-projecting flanges D D at the bottom, and clamps the screen between the two flanges D D at the bottom. Little openings 0 r are cut into the under side of the tube portion D.

Supported on the inner sides of the window-frame F are vertical tubes F, with a slot cut on their inner side to receive the edges of the netting E. The longitudinal strands of the netting E are made of soft annealed wire, which will wrap around the roller II readily to make acompact roll. Transverse strands fare made of tempered steel wire to make the netting stiff in the transverse direction. These tempered wires should be inserted at short intervals through the entire screen. \Vhere the window is very large, all of the transverse strands should be made up of this material. The ends of the stifi transverse Wires are kinked sharply from side to side to cause them to be retained in the tube F, as indicated in Fig. (5.

The bottom rail of the sash Ais grooved to receive the tubular binding D on the upper edge of the screen.

At intervals gripping devices B B are inserted to engage the binding D in the apertures r r on its under side. These for ordinary purposes are best made as shown in Figs. 2, 5, and 5, where the bracket L is fastened at the top of suitable mortises cut into the bottom rail of the sash, and on this bracket are supported the oppositely-facing levers B, which are pivoted at 6, having hooks at the bottom. These levers cross like the blades of a pair of shears and are held together at the top by the coiled spring 6', which holds the hooks at the bottom normally in engagement with the binding D of the screen below. The books at the bottom are rounded, so as to pass easily over the tubular binding D.

Between the upper ends of the levers B is supported a little cam nfor opening the same. This is actuated from the push-button O, with its shank O projecting through a suitable socket O on the bottom rail of the sash. The pin C strikes against the little curved lever g, which is on the little shaft of the cam o and actuates the same. WVhen the push-button Ois pushed in and turned in a little to one side, the lug 17. passes through the slot 11. and engages one or the other of the little notches n, which retains the same in the unlocked position. In Figs. 16 and 17 a modification of this attaching device is shown in which the levers B13 do not cross. One of the levers is rigidly On the upper edge of secured to the sash and the other is pivoted thereto, and in this instance the little spring 6 holds the same always in engagement with the binding at the top of the screen and the the top of the lovers to engage the cams o.

On the under side of the meeting-bar of the top sash may be secured a strip or strips of rubber K, (see Fig. 11,) which project forward next to the glass to close the opening at that point formed by the opening of the sash and prevent the entrance of insects at that point. A more perfect protection at that point is shown in Figs. 12, 13, and 14, in which a small roller M is placed in one of the meeting-rails, and a light screen M will unwind at that point and prevent the passage of any insects at that point between the sash. It will be noted from this description that my device can be greatly varied in its details without departing from my invention.

The special screen M will be used only in very heavy windows, the excluder K (indicated in Fig. 11) being the most convenient, though not so effective. I might enumerate other variations, but it is unnecessary, as they would occur to the skilled mechanic in this class of work from intimations and statements contained in the foregoing description.

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

1*.
