JAMES K. NELSOIE OF MARISSA, ILLINOIS.
WINDOW-SCREEN.
SPECIFICATION forming part of Letters Patent No. 268,716, dated December 5, 1882. Application filed April 14, 1882. (No model.)
To all whom it may concern:
Be it known that I, JAMES K. NELSON, of Marissa, St. Clair county, Illinois, have in vented a certain new and useful Improvement in Window-Screens, of which the following-is a. full, clear, and exact description, reference being had to the accompanying drawings,
' forming part of this specification.
My invention relates to a screenmade in two pieces, working in grooved cleats or strips secured to the stiles of the window-frame, as shown, the length of the two being equal to halt the length of the window, or the length of one sash.
In the drawings, Figure l is an elevation, and Fig. 2 is a cross-section on line 2 2, Fig. 1.
A represents thelower and B the upper sash of a window, arranged in the frame 0 in the usual manner. D D are grooved strips secured to the window-framc inside the sash A B and parallel therewith.
E E represent the two independent screens, the combined length of the two, as before stated, equaling halt the length of the window. They may be made of the same length; but I prefer to make the lower one longer than the upper, as shown. The frames of the screens have tenons or ribs 6, which work in the grooves of the strips D. Instead of the grooves being in the strips and the ribs on-th'e screen-frames, they may bechanged about, vice versa. Suitable spring-catches, F, are secured to the screenframes to hold them to any adjustment. It will thus be seen that as the screens are independent of each other, and the length of both equal to half the length of the window, both may be put up or both down, or one up and the other down, as shown, and thus exclude flies, 850., whichever sash is open or partly open. As shown in Fig. 1,0ne sash could be partly up and the other partly down, to admit air at the top and bottom of the window; or the upper sash could be lowered and the lower screen raised, or the lower sash raised and the upper screen lowered.
I claim as my invention The combination of frame 0, sash A B,
grooved strips D, and screens E E with ribs e and catches F, all substantially as and for the purpose set forth.
