SPECIFICATION forming part of Letters Patent No. 537,109, dated April 9, 1895. Appirettio filed August 29,1894.. serial' No: 521,638. (No model.)Y

To otZZ whom t may concern:

Be it known that. we, SOLOMON M. HARRIS and MICHEL BREISOH, both of New York city, New York, have invented an Improved Window-Screen, of which the following is a specification.

This invention relates to a window screen which is adapted to vbe operated by the sliding sashes, so as always to protect the openings below or above such sashe's.

In the accompanying drawings, Figure l is an elevation, partly in section, of our iinproved window'screen. Fig. 2 is a longitudinal section on line 2, 2, Fig. l; Fig. 3, a similar section, showing the'sash b', in its lowermost position; Fig. 4, an enlarged vertical section through the screens c, d, and Fig. 5 a detail of the fastening devices c.

The letter a, represents a window frame having a hollow lower box a2, and preferably a hollow upper boxe'.

21,5', are the upper and lower sliding sashes, of the usual or suitable construction.

To the lower railb2, of the lower sas/h b', there is adapted to be secured by catches c', the rigid frame of a window screen c. This screen is provided with grooves c2,in its side rails, adapted to be permanently engaged by pins d', of a second screen d. When the sash b', is lowered, both the screens c, d, are lowered into the hollow box a2, through a slot a3 (Fig. 3); but when the sash b', is raised, the screenc, will be drawn up with it, to close the space beneath such sash. If the sash b',

is raised still farther, the screen c, will by pins d', and grooves c2, raise up the screen d, and in this way the entire open space beneath the sash may be protected by the screens (Fig. 2). Y

The object of making the screen in two parts is to permit it to be received within a comparatively shortbox a2, of the frame a.

VThe topv rail-c3, of screenVc, should have a beveled rear edge, to engage a packing strip c4, of slotcts, so as to closeA said slot against the weather when the screen is lowered.

Upon thetop rail h3,of upper sash Z),is supported latop screen e, which rests upon 'the sash by its own gravity and is raised and lowered with the same. The frame ct, should, of course, be provided with a slot a4, at the lower end of box a', to permit the screen e,

to be slid into such box. What we claim is A window frar'ne having a box in its lower portion, and the lower sash, having engaging hooks fastened to its lower edge, combined with the two vertically moving screens, one of which is provided with pins with which the hooks engage, and grooves in its side rails, and the other having pins which catch in the grooves, whereby when the lower sash is closed it engages with one of the screens, and when raised it successively raises both of the screens, substantially as shown.
