WINDOW-SCREEN.

SPECIFICATION formingpart of Letters Patent No. 694,319,

dated February 25, 1902.

Application filed September 25, 1901. Serial No. 761563. (No model.)

To all, whom it may concern:

Be it known that I, E WIN L. LLOYD, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Window-Screens, of which the following is a specification.

My invention relates to adjustable windowscreens, the object of my invention being to produce a metallic-framed screen of this character possessing lightness, rigidity, increased strength, and ease of adjustment.

The improved screen forming the subject of my invention is made entirely of metal and is fully shown in the accompanying drawings, in which- 7 I Figure 1 is a front elevation of a screen made in accordance with my invention. Fig. 2 is a rear elevation of the screen, illustrating a detail of my invention. Fig. 3 is a vertical sectional view of the screen, on a slightly-enlargedfscale, taken on the line a a, Fig. 1. Fig. 4 is a similar sectional view illustrating another detail of my invention. Fig. 5 is a longitudinal sectional view of the screen, taken on the line b b, Fig. 1, the central portion being broken away. Fig. 6 is a perspective view of a corner of the screen, illustrating the manner of securing the side pieces to the top and bottom rails; and Fig. 7 is asimilar perspective View taken from the rear of the screen and illustrating a further detail of my invention.

In the drawings herewith, 1 represents the upper rail or cross-bar of the screen, 2 the lower rail, and 3 the side pieces secured at 4 to the top and bottom rails 1 and 2. The top and bottom rails 1 and 2 are each providedwith tubular portions 5 and 6 for the purpose of stifiening said rails, and the metal composing the upper rail is extended above its tubularportionfi, so as to form a closing-strip 7 for the window-sash when the latter is brought against the tubular portion of the upper rail. In addition to the tubular strengthening portions 5 and 6 the edge of the outer wall of both top and bottom rails is turned over to form the tubular beads 8 and 9, which act as further stiffening-braces. The side pieces 3 have beads 10 on both edges of the same, which beads are preferably filled with 12 0f such top and bottom apertures in strengthening or stifiening wires 11 and provide j suitable projections which may be grasped by the hands to. raise or lower the screen. The side pieces 3 are secured to the top and bottom rails by striking up portions rails and forming said side bars, to which the portions 12 are adapted'and then bending over the port-ions'12 upon the outer surface of the side pieces. In the present instance Ihave formed cuts in the top and bottom rails in the shape of a Maltese cross, which provide four retaining pie ces or portions 12, adapted to apertures suitably disposed to receive the same in the ends of the side pieces 3. By this means of fastening, all necessity of soldering theparts together is avoided.

The wire-netting or screen proper, 14, is secured between the walls of the upper and lower rails 1 and 2 by any suitable means. For instance, holes 15- may be formed in said rails, and after the netting or screen has been set in place a fine wire 16 may be threaded through said apertures to hold the netting in place. This wire is also, run through similar apertures 15 in the side pieces 3. Instead of employing this method of fastening the netting in place I may secure it tothe top and bottom rails and side pieces by any other approved means.

For the purpose of making the screen adjustableI provide the extensible metallic side wings 17, the upper and lower portions of which are adapted to lie between the walls of the top and bottom rails. These side wings 17 extend the full height of the sash, and when they are in proper position within the window-frame the upper portion of the same is in line with the strip 7 of the upper rail, whereby a continuous closure is provided for the gap between the window sash and screen extending from one side of the window-casing to the other. The wings 17 are strengthened by turning to form the beads 18, which beads preferably receive the stiffening-wires 19 and 20. In order to guide these wings in extending or contracting the same with relation to the screen, the wire 19 has upper and lower portions 21 extending at right angles to the same,

7 screen forming the main portion raising and lowering the same which portions are adapted to enter the beads 8 and 9, formed on the outside wall of the top and bottom rails 1 and 2.

For the purpose of guiding the screens when and also to provide a suitable housing for the outer beaded edge of the extension-pieces 17 I provide the channel-pieces 22, substantially U-shaped in cross-section and secured to the inside of the window-frame by suitable nails 23, as illustrated in Fig. 5.

Under ordinary conditions there will be sufficient friction between the side walls of the top and bottom rails and the extensionpieces 17 so that said extension-pieces may be held in any predetermined position; but for the purpose of insuring the extension of said wings or pieces I provide spiral springs 24, adapted to the tubular portions 5 and 6 of the top and bottom rails, such springs engaging projections 25 on said side wings and stopped at their opposite ends by means of a pin or other suitable member 26, inserted in said tubular portions 5 and 6.

The side wings or extension-pieces are preferably perforated with fine holes, as shown at 27, and these perforations may form any predetermined design, being preferably made at a single operation by a suitable die.

.In Fig. 4 I have illustrated a modification of the structure in which the tubular portion 5 of the upper rail 1 is flattened on one side, while the upper portion 7 is bent so as to come over the edge of the side pieces, such construction permitting the screen to be used with a window that may be raised and lowered at will to one side of the same; The style of of my invention, however, is adapted to have the under edge of the lower portion of the sash rest against the outside of the tubular portion 5.

Having thus described my invention, I claim and desire to secure by Letters Patent l. The combination in a metallic windowscreen, of the upper and lower rails formed of sheet metal bent upon itself and having tubular strengthening portions, side pieces secured to said rails and forming a frame, woven-Wire netting secured within said frame, and side or end extension-pieces for said frame lying between the walls of the top and bottom rails.

2. The combination in a window-screen, of the upper and lower rails formed of sheet metal bent upon itself and having tubular strengthening portions, side members having their edges formed to serve'as strengtheningsupports, Woven-wire netting secured to the frame formed by said side pieces and the top and bottom rails, and side or end extension members for said frame lying between the walls of the top and bottom rails, said extension members being perforated.

3. A metallic Window-screen comprising the top and bottom rails each formed of a single and the top and bottom piece of metal, and shaped so as to provide tubular strengthening portions ator near the center of the same, metallic side pieces also strengthened and secured to said top and bottom rails, the said top and bottom rails having two walls, extension members lying between said walls and woven-wire netting secured between the walls of said top and bottom rails and to one side of the metallic side pieces, thereby permitting free movement of the extension members.

4. A metallic window-sash having top and bottom rail-sections formed of sheet metal bent upon itself and having tubular portions for strengthening purposes, a lip formed by the double portion of the metal composing the upper rail and disposed above the tubular portion of said rail, said lip adapted to engage the windoW-sash when the screen is in use, side members secured to said top and bottom rails, and woven-wire netting secured to the frame formed by said side members rails.

5. The combination in a metallic windowscreen, of the top and bottom rails formed of sheet metal bent upon itself, side members secured to onewall of said rails, and exten+ sion-pieces carried by said top and bottom rails adapted to slide between the walls of the same. i

6. The combination in a metallic window screen, of the top and bottom rails formed of sheet metal bent upon itself, side members secured to one wall of ,said rails, and perforated eXtension-pieces carried by said top and bottom rails and adapted to slide 7 between the Walls of the same.

7. The combination in a metallic window screen, of the top and bottom rails formed of metal doubled upon itself, side members se cured to said top and bottom rails to form the frame of the screen, and extension-pieces for the ends of said frame, the upper and lower ends of said extension-pieces lying between the walls of the top and bottom rails.

8. The combination in a metallic window screen, of the top and bottom rails formed of metal doubled upon itself and having tubular strengthening portions, side pieces secured to one wall of said top and bottom rails, extension-pieces for the ends of said frame lying between the walls of the top and bottom rails, and springs carried by said tubular portions of the rails, said springs engaging the extension-pieces lying between the Walls of the rails and serving to maintain said pieces in the extended position.

9. The combination in a metallic windowscreen, of the top and bottom rails formed of metal pieces bent upon themselves and having tubular strengthening portions, the lower edge of one portion of each rail being bent upon itself to form a bead, extension-pieces carried by said rails, and wires carried by the edges of said pieces for strengthening the same, one of said wires being bent and adapttop and bottom rails, said extension-pieces lying between the flange of the top rail and forming with said flange when extended, a 15 continuous closure for the edge of the sash abutting the upper rail.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
