JOHN W.-OARMAN, OF FORTATKINSON, WISCONSIN, ASSIGNOR OF A PART TO EDGAR TERHUN E, OF CHICAGO, ILLINOIS, AND GEORGE F. PATTER- SON, OF FORT ATKINSON, WISCONSIN.

W!NDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No.- 277,111,,dated May 8, 1883.

Application filed February 15, 1883. (No model.)

To all whom it may concern Be itknown that I, JOHN W. OARMAN, a citizen of the United States, residing at Fort Atkinson, in the county of Jefferson and State of Wisconsin, have invented a new and useful Screen for Windows, of which the following is'a specification.

My invention relates to improvements in window-screens in which a roller and springs are used in conjunction with the sash or frame of the window; and the object of my improvement is to stow away the screen, when'desired, outof the way and automatically restore it to position again. I attain this object 1 5 by mechanism illustrated in the accompanying drawings, in which Figure 1 is an elevation, showing sash raised and exposing the screen. Fig. 2 is an elevation with sash' raised and screen stowed away, with the screen-guard in position covering the screen in thesash. Fig. 3 is a vertical section with the screen-guard secured on the window -sill by a lock and sash raised. Fig. 4 is a detail with the bottom of the sash 2 broken away, showing screen-roller in section. Fig.5 is a detail of screen-guard, show ing hook for securing thesanie to sill and the screen attached to the bottom of it. Fig. 6 is a detail topview ofthe lock sunk in the sill. Fig. 7 is a sectional view, showing one scroll-spring therein. Similar letters refer to similar parts throughout the several figures. 5 A is the lowerrail of the sash, in. the bottom of which is groove B for the reception of roller 0. In each end of'roller'O is a cupshaped cavity, in the center of which are pins d, driven into the roller, leaving the ends to 0 project sufficient for bearings in the hangerplates 0 c, which are made to cover the ends of the roller, and are permanently secured to the edge of the sash above. To the hangerend of the roller with springchamber and.

plates 0 0, about the pin-hole inside of the 5 hangers, are secured bands or rings f, which are made to fit loosely inside of the cavity 9 in roller 0, and thereby becomes a part of the hanger. (Shown in Fig. 7.) The roller 0 is designed to rest and revolve upon the pins (1; but, if desired, they may be left to rest and revolve upon the rings or flanges f. The roller 0 is provided with springs c to operate it, which are in this case in the form of a scroll, the side view only being shown. They are placed inside of the rings f, one end'of which is secured to the ring and the other to the center-pin d.

The upper edge of the screeucloth D is secured to roller 0, and the lower edge to the inside of screen-guard E, Figs. 4 and 5. The 6 guard is trough-shaped, the edges beingturned upward. The lengthis equal with the width of the screen. When in position as in Fig. 2, it covers groove B like the covering of a box, inclosing the screen completely.

The springs c are set under full tension when the screen is fully unrolled. Release the screen-guard and the screen will roll to position.

The window-sill H is provided with a lock, 7Q G, sunk in the 'sill to lock down the screenguard E.

When the sash is lowered from the position shown in Fig. 2, the catch F enters slot a in lock G, pressing spring I one side until it snaps into the notch, whichv locks it to the sill H.

Spring I projects forward through slot J in the window-sill for the convenience of unlocking the guard.

To set the screen as in Fig. 1, when the sash is down, leave the screen-guard locked and raise the sash. To stow away the screen again, unlock the screen-guard and the springs 6 will roll the screen to position, as shown in Fig. 2. i

The stow-away roller O may be located in or upon the window-sill instead of the sash, and the guard locked to the sash, merely reversing the order of operation. go

I am aware that similar springs and rollers have been heretofore used for hanging window-curtains, and are not new: Therefore I I do not claim such a device, broadly; but

What Idoclaim as my invention, anddesire ening and releasing the lower end of the to secure by Letters Patent, isscreen, substantially as and for the purpose In screens for Windows, the roller 0, inountset forth. ed upon thewindow-sash, with mechanism JOHN W. GARMAN. [L. s.] 5 for stowing the same automatically away for Witnesses:
