SPECIFICATION forming part of Letters Patent No. 794,470, dated July 11, 1905.

.Application filed February l5, 1905. Serial No. 245,668.

To all whom it may concern:

Beit known that I, WILLIAM E. SHERwooD, of Oneida, in the county of Madison, in the State of New York, have invented new and useful Improvements in Window Screens, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of win- Io dow-screens which comprise two frames each provided with a sheet of wire-cloth and which are joined slidably, thereby rendering them adjustable, so as to permit the same to be placed in window-frames of different widths, and the invention has special reference to the style of screens which have their members formed from sheet metal.

The main object of the present invention is to produce a screen ofthe character referred to which shall possess great strength, rigidity, and durability, and at the same time shall be inexpensive in its manufacture and also.

present a neat appearance.

To that end the invention consists in the novel construction and arrangement of the component parts of the screen, as hereinafter fully described, and set forth in the claims.

In the accompanyingdrawings, Figure 1 is a front view of a window-screen embodying my invention. Eig. 2 is an enlarged vertical section taken on the dotted line X X in Fig. 1. Fig. 3 is an enlarged longitudinal section taken on the line Y Y in Fig. 1 viewed in the direction indicated by the arrow. Fig. 4f is an enlarged perspective View of a corner portion of the inner screen-frame, and Fig. 5

is a like view of a corner portion of the outer screen-frame.

Similar letters of reference indicate corresponding parts.

This screen comprises two frames A B, sliding one in the other, whereby it can be lengthened or shortened horizontally to accommodate itself to window frames of various widths, which frames are formed from sheet metal of any suitable kind. The inner frame A is composed of top and bottom members c a and one side member at. Each of these frame members consists of a plate which is primarily folded longitudinally upon itself to form two strips one strip of each member being inserted between the meeting member and abuts against the fold thereof.

D represents a sheet of the usual wire cloth ory netting, which has its top, bottom, and one side margin inserted between said strips and also abutting against the said folds, through which overlapping strips pass rivets Z d, which rigidly unite the frame members.

The said plates or members a ct a', with the inserted strips of wire-cloth, are then bent longitudinally on lines parallel to the aforesaid folds, thereby producing lianges c e e, disposed at right angles thereto. The forming of lflanges at the top and bottom causes the wire-cloth to be tightly stretched in one direction and securely clenches the same to the frame members and Vat the same time adds strength and rigidity to the frame. To the front of said inner frame I apply a vertical stay A', which consists of a metal plate folded in the manner aforesaid to form two strips f f, one of which is inserted between the strips b of the top and bottom frame members A A and preferably secured by means of rivets g g. The other side margin of the wire-cloth D is inserted between the latter strips and abuts against the fold. The plate or stay is then bent at right angles on a line parallelto the line of fold to form a flange t, whereby the said wire-cloth is securely clenched and tightly stretched in the other direction. The outer frame B is composed of top and bottom members c' c' and a side member c. Each of the said frame members vl vl consists of a plate that is primarily folded longitudinally upon itself at the center of the width to form two strips jj' and thence bent at right angles on a line parallel to the fold to form a iiange lo. The side member rl is likewise folded and-bent to form two strips la' c and a flange Z.

the two strips of E represents the other sheet of wire cloth or netting, which has its margin inserted between the strips j Za and clenched in the flanges 7c Z the same manner as the aforesaid wire-clothD. The strips j /r are lapped one onto the other and rigidly united by means of rivets m m. The said flanges 7c /c of the top and bottom members are further bent to form longitudinal guards, as indicated at n n and more clearly shown in Fig. 5 of the drawings. These guards engage the top and bottom flanges of the inner frame A and sustain Said frame laterally in the outer frame.

By bending the Lipper and lower members of the outer frame, as aforesaid, they assume a U shape in cross-section, and the wire-cloth is tightly stretched in one direction.

To the back of the outer frame is applied a vertical stay F, which consists of a metal plate, which is provided with a double fold in which the other margin of the wire-cloth E is clenched, and thereby stretched in the other direction. The stay has its ends inserted between the strips jj' and rigidly secured by rivets 0 0.

G represents an auxiliary vertical stay, which is disposed opposite the stay F and rigidly secured at its end to the guards in any suitable manner, preferably by means of rivets a2 a2, between which stays the 'frame A slides. This auxiliary stay is formed with an inwardly-projecting flange o', which is adapted to engage the flange /z of the stay A' on the inner frame when the frames are extended to limit their movements.

I preferably form the auxiliary stay G of a plate folded and bent longitudinally like the stay A. The said stays A G are designed to lie close to the wire-cloth to effectually eX- clude flies, insects, zac.

What I claim is` l. A'win'dow-screen comprising two slidably-joined metallic frames, having their members composed of plates, each folded longitudinally at the center of its width to form two strips, one strip of each plate being inserted between the strips of the meeting plate and rigidly united, and a sheet of wire-cloth secured between the strips of each frame, as set forth.

2. A window-screen comprising two slidably-joined metallic frames having their members composed of plates, each primarily folded longitudinally at the center of its width to form two contiguous strips, one strip of each plate being inserted between the strips of the meeting plate and rigidly united, and each plate secondarily deflected at right angles on a line .parallel to the fold to form marginal flanges,

and the sheets of wire-cloth inserted with their marginal portions between the strips of the respective members and clenched within the said flanges, as set forth.

3. A window-screen comprising two metallic frames sliding one in the other and each having a top, bottom and one side member,

each having a top, bottom and one side member, the inner frame having its members formed L-shaped in cross-section, the' outer frame having its side member likewise formed and its top and bottom members formed U- shaped in cross-section, and the sheets of wire cloth inserted into said frames and clenched therein, as set forth.

5. A window-screen comprising two metallic frames sliding one in the other and each composed of a top, bottom and one side member, the inner frame having its members each composed of a plate folded longitudinally at the center of its width to form two contiguous strips and one strip of each member inserted between the strips of the meeting member and rigidly fastened, the plates each deiiected on a line parallel to the fold to form a flange, the members of the outer frame, also composed of plates likewise folded and deflected, the top and bottom fianges of said outer frame terminating respectively with downwardly and upwardly deflected guards engaging the lianges ofthe top and bottom flanges on the inner frame, and the two sheets of wirecloth having their marginal portions inserted between the strips of the respective frames and clenched within the said flanges, as set forth.

6. A window-screen comprising two metallic frames sliding one in the other and having their members each composed of a plate folded longitudinally upon itself at the center of its width to form two strips, a vertical stay. rigidly connected at its end to the top and bottom members of the inner frame,.a pair of vertical stays connected at theirends to the yhaving their ends inserted between the strips and rigidly secured thereto, as set forth.

IOO

sheets of wire-cloth secured between said A strips, vertical stays secured at their ends between the strips of the top and bottommemy n A bers of the frames, and arranged one in the path of the other to limit the outward movement of the frames, as set forth.
