WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 312,685, dated February 24, 1885.

Application mod May 1i, isei. (No model.)

To a/ZZ whom, it may concern-.-

Be it known that I, MAncnLLUs L. WHIT- COMB, of Muskegon, in the county of Muskegon and State of Michigan, have invented a new and useful Improvement in Vindow blinds to be closed, a-nd4 also allow the shutters to be turned open, orto a horizontal position, and not interfere with the windowscreen; that may be readily put in or taken out without the aid of tools.

In order to aid others skilled in the art to which iny invention belongs to make and use it, I will proceed to'describe its construction and operation with reference to the several drawings, forming a part of this specilication,

in which# Figurel is an elevation in perspective ol' my invention. Fig. 2 is a cross-section of the saine, having the blinds closed. Fig. 3 is a detached perspective of the screen-frame. Fig. 4 is a top and` edge view of the tensionspring f'. v

In the drawings, Fig. 1, F represents the window-screen; G G, the blinds;` D D, blindstops; H H, blind-rods5'F2, the screen. In Fig. 2, F is the inward-curved bottoni crossrail of screen-frame, (see also Fig. 3;) C G, janib-casings, dd, check-stops; DD,windowstops; e c', grooves in said stops; ci a', grooves in blind-stops; BB, upper sash broken away; I I, blind-hooks; g g, blind-slats turned to a horizontal position, or open; I,screen-fra1ne knob; S S, stiles of the screen-frame.

To operate the screen on the outside of/the window next to the blinds,I provide the blindstops D D with the grooves a a. (See Fig. 2.) The stiles S S of the screen-frame are rabbeted, as shown at f of Fig. 2, thus forming a tongue sufficiently thick to fill the channels a a of the blind-stop, bringing the stiles S S of the screen lush'with the face of the window-sash. I cut the channel a in the blindstop about twice the dept-h of the channel a in the opposite stop. The' tension-spring f, I locate in the deep channel a', as shown in Fig. l, where broken away.

To place the screen in position, I insert the long tongue of the screen-stile into vthe deep channel a of the blind-stop, forcing the frame against the spring f until the opposite stile ofthe frame meets the channel@ ofthe blindstop,when the springf will force thetongued portion of the' opposite stile into the channel u. The frame, being made sufficiently wide, is held in this position by the spring f,which also allows the frame to be raised or lowered by grasping the knob K on the inside of the frame.

It will be observed that when the blinds are closed andthe blind-slats g g are opened, as shown in Fig. 2, the blind-hooks I I and blindrods H H project toward the window-sash; and in order to prevent these part-s from interfering with the window-screen I curve the bottom cross-rail, F', inward, as shown in Figs. 2 and 3. This frame, when used on the outside of the window, may be noa-de the size of the lower sash, as shown in Fig. l, and can be taken out by pressing sidewise against the spring j until the stile `on the opposite side of the frame draws out of the channel a; and when the screen is niade shorter than the sash said sash may be lowered to ineet it, and the screen may be raised and lowered to open or close the blinds or shutters without re1noving said frame from the window. One of the stiles of the screen-frame is provided with a deep rabbet, as shown at f of Fig. 2, thus forrning a long tongue to fit into the deep groove a on the bliand-stop D, for the purpose of inserting the frame, as set forth, in raising or lowering the screen, and said spring is made sufficiently stiff to hold the screen up when raised. Ventilation may be obtained at the top and bottoni of the window by using two screen-frames, lowering the upper sash, raising the lower one, leaving one screen down and raising the other; or ventilation can be had at the top or bottoni of the window with but one screen. i

Having thus described niy present invention, what I claim as new, and desire to secure by Letters Patent, is-

ICO

1. The combination of the screen-covering, i the screen-covering, the stiles S S, tongued, as the sereenfmme consisting of the tongued specified, and the inwardly-curved cross-mil 1o sbiles S S, the transverse inwardly-curved erossrail F, thetension-spring, and the blind- 5 stops, grooved, substantially as and for the purfol-bh. l
