SPEGIFlCATION forming part of Letters Patent No, 794,469, dated July l1, 1905.

T all whom it nfl/ty concern:

Be it 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 in which the frames are composed of sheet metal and slide in guides or tracks 'secured to the window-frame and at the same time are automatically adjustable to accommodate themselves to window-frames having varying widths.

The main object of this invention is to produce a metallic Window screen which shall be simple, strong, and durable in construction, efficient in its operation, and at the same time inexpensive to manufacture.

Another object is to produce a construction which shall permit of quick and easy placement in the window-frame and removal therefrom and, furthermore, shall permit the wirez 5 cloth to be readily removed and a new piece to be applied when required.

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

In the accompanying drawings, Figure 1 is a front View of my improved Window-screen. Figs. 2 and 3 are enlarged detailed front views of the upper corner portions of the screen, partly broken away. Fig. 4 is a transverse section on the dotted line X X in Fig. 3. Fig. 5 is a vertical section on line Y Y in Fig. 2. Fig. 6 is a transverse section on line Z Z in 40 Fig. 2. Figs. 7 and 8 are side and end views,

respectively, of the corner-piece of the main or outer frame; and Fig. 9 is a perspective view of a corner portion of the inner or secondary frame.

Similar letters of reference indicate corresponding parts.

A A A denote the top, bottom, and one of the side members of the outer or main fratrie of the screen, and A denotes the other side member thereof, which is adjustable, as will be shortly described. This frame is supported slidably in vertical guides or tracks B B, preferably formed of metal and fastened to the window-frame O in the well-known manner. The said frame members A A A are each composed of a sheet-metal plate folded longitudinally at the center of its Width to form a tubularvmarginal channel a and two inwardly-projecting parallel flanges b. These frame members are rigidly united by metallic L-shaped corner-pieces cc, which are solid and are inserted into the ends of the channels a a. Said corner-pieces are formed with webs CZ d, which are embraced by the flanges of the top and bottom members A of anges are in turn embraced by flanges of the side member A, and through said parts pass rivets c c. 'Ihese webs d d serve as spacingblocls maintaining the iianges proper distances apart to permit the insertion of the sec- 7 0 ondary or wire-cloth frame hereinafter described.

The frame member A is composed of a sheet-metal plate, folded longitudinally at the center of its width to form a channel f, and two inwardly-extending parallel wide strips g g, which loosely embrace the secondary or screen-frame proper, which will be shortly referred to. In the ends of the channel of said frame member A are rigidly secured 8O metallic L-shaped corner-pieces /t L by means of rivets c' c'. Said corner-pieces slide in the end portions of the channels a a of the top and bottom frame members. In each of said channels ais disposed a coiled springj, which bears at its inner end against a block or diaphragm k, rigidly secured therein and pressing with its opposite or outer end against the cornerpiece I, rigidly secured to the frame member A', as aforesaid. Said springs serve to force 90 the said frame member outward, and thereby maintain the frame in the guides B B. By this arrangement the said frame member A is permitted to yield sidewise in relation to the window, and thereby rendering the main screen-frame automatically adjustable to acthe frame, which 65 I the main-frame member A.

commodate itself to any variations that may l exist in the distance between the guides or l tracks.

By forming the aforesaid frame members or plates A A A A' in the manner described it will be observed that a double frame is produced which possesses great strength and rigidity. I do not,lhowever, limit myself to the means employed for uniting the frame members as shown, as they may be otherwise fastened. The membersZ Z Z Z of the secondary frame also consist of metallic plates which may be united by any suitable means, and to this frame the usual wire cloth or nettingD is secured in'any convenient manner. I prefer, however, to fold each of these plates longitudinally upon itself at the center of its width to produce a double frame and insert the marginal portions of the wire-cloth therein, so as to abut against the folded portion.. I then impart a second fold to the plates and insert AWire-cloth, thereby firmly clenching the wirecloth to the frame. This second fold serves to tightly stretch the wire-cloth and produce a bead, as indicated at m. This secondary frame is inserted with its beaded portion endwise between the fianges Z) Z of the main frame and secured removably therein by means of bolts or screws n n. The application of the secondary frame to and its removal from the main frame is readily permitted by detaching The strips of the said frame member are yielding and have their free edges deflected inwardly to form lips, as indicated ato 0. These lips are adapted to engage the heads of the bolts or screws and their nuts, which constitute stops limiting the outward movement imparted to said frame member by the aforesaid coiled springs, thereby maintaining the frame intact when removed from the guides or tracks B B. In order to detach the frame member A', its strips are sprung apart, so as to cause the lips to disengage from the said heads and nuts of the bolts.

It will be understood thatI do not limit myself to the form of stops shown, as other means may be employed for the purpose. The ends of the strips of the meeting members of the secondary frame are lapped one onto another, and one of the strips of each member is extended beyond its companion l strip and folded onto the other member with the wire-cloth, thus producing an interlocking joint, as` clearly shown in Fig. 9 of the drawings.

It will be seen that the secondary frame can be readily removed from the mainframe by the removal of the bolts or screws nu. It will also be observed that the main frame can be conveniently removed from its guides or tracks.

0 denotes a handle which is employed for raising and lowering the screen and may be of any suitable form. I prefer, however, to

construct the same from a piece of sheet metal and fasten the same to the lower member of the main or outer frame.

What I claim is- 1. In combination with a pair of vertical guides secured to the window-frame, of a screen comprising a main frame sliding in said guides and having one of its side members rigidly united with the top and bottom members, and the other side member adjustable, a secondary frame'having its members rigidly united and secured removably within the main frame, and the wire-cloth secured to said secondary frame as set forth.
