FOREST M. LAMPSON AND GEORGE \V. HOGBEN, OF RlPON, VISOONSIN,

ASSIGNORS TO THE RIPON VIBE DOOR AND PANY, OF SAME PLACE.

WINDOW seamen COM- ADJUSTABLE WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 361,825, dated April 26, 1887.

(No model.)

To aZZ. whom it may concern.-

Be it'known that we, FOREST M. LAMPSON and GEORGE W. HOGBEN, both of Ripon, in the county of Fond du Lac and State of Wiscousin, havednvented a new and Improved Adjustable WVindow-Screen, of which the fol lowing is a full, clear, and exact description.

Our invention relates to adjustable windowscreens, and has for its object to improve the construction of the screens for which United States Letters Patent No. 328,69l were issued to us October 20, 1885, in such manner that gulde-pins separatefrom the springs, by which the adjustable strips or plates are forced outward, may be dispensed with, and the spring pressed plates will be held snugly to the face of the main screen-frame.

The invention consists in certain novel features of construction and combinations of parts of the window-screen, all as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is an elevation of a window-frame and its sashes with our adjustable screen applied as in use. Fig. 2 is a sectional plan view taken on the line :10 m, Fig. 1, and partly broken away; and Fig. 3 is an enlarged sectional plan View of one of theside bars of thescreen.

The window-screen is made with a frame, A, to which the netting wire or fabric B is held in any approved way, say by means of beaded moldings b, braided over the netting to the irame A, or by staples or tacks.

Over the opposite side bars, a a, of the frame A there are placed loosely the adjustable strips or plates 0 (J, and to opposite ends of these plates there is fixed the outer end of the arm Z of an- L- shaped wire, spring, D, the extremity of the other arm, d, of which is fixed, by staples or otherwise, at 'd ,'to the frame side bar, a. The arm (I of each spring D passes through a guide eye or staple, e, fixed to the side bar, a.

It is obvious that the passage of the arm portions d of the springs D through the eyes 0 011 frame A hold the springs to place against the frame, while allowing ample freedom of movement to the side plates, 0 O, on the frame,

and separate guide-pins for the plates are unnecessary.

At about the vertical center of each of the side bars, a, of frame Athere is fixed in a horizontal slot, f, of the bar a wire or rod, F, on which is fitted loosely an eye or loop, 9, formed by v the handle-loop G. K

\Vhen the sash of the window is openedthelower sash, H, for instancethe wire screen may be easily placed in the opening by taking hold of the opposite loops G G and drawing the opposite plates 0 O inward, so that they may pass within the stop-beads I on the windowframe, and when the screen -frame A is in proper place the loops G will be released and the opposite plates 0 C will instantly be forced by the springs D against the window-frame and make a close joint therewith to exclude insects or dust. If desired, the screen may be placed in position by entering one side bar, a, of it in the sash way or groove and then drawing back the opposite plate 0 by its handle-loop G until the other side bar may pass the adjacent stop-bead on the sash and enter the sashway, whereupon the loop G will be released and the screen will be held securely by the springs.

It is evident that the yielding and Springpressed plates 0 0 allow for considerable variation in the width of window-frames which the screen will fit closely.

A spring-pressed plate, 0, at one side of the frame A wouldsuffiee in many cases; but we prefer to use the plates at both sides of the frame, as shown and above described, as they afford a better chance for a closer fit of the screen-frame at both sides of the window-frame and between the sash and sill or head of the window-frame than one plate alone would afford, as will readily be understood.

Having thus fully described our invention,

described, whereby the plate 0 will be held flat 10 to theframe A and can be adjusted thereon,

as set forth.
