SPECIFICATION forming part of Letters Patent No. 671,840, dated April 9, 1901.

To a/ZZ whom it' muy concern:

Be it known that I, JOHN B. SIMMONS, a citizen of the United States, residing at Shreveport, in the parish of Caddo and State of Louisiana, have invented a new and useful Window-Screen, of which the following a specification.

The invention relates to improvements in window-screens.

The object of the present invention is to improve the construction of window-screens and to provide a simple and comparatively inexpensive one adapted to slide vertically between the upper and lower sashes and to be operated by the lower sash and provided with an opening to permit the sashes to be fastened with an ordinary sash-fastener and having means for automaticallycovering the said opening when the screen is at the bottom of the window and for similarly uncovering the opening when the screen is raised.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is an elevation of a window provided with a screen constructed in accordance with this invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a horizontal sectional view on the line 3 3 of Fig. 2. Fig. 4 is an enlarged vertical sectional view of the lower port-ion of the windo w,illustrating the arrangement of the slides when the screen is down. Fig. 5 is a detail View illustrating the manner of securing the slide to the screen.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

l designates a vertically-movable rectangular window-screen inountedin suitable guides 2 of a window-frame 3l and located between the upper and lower sashes 3 and 4 and connected with the lower sash 4 by cords 5 or other suitable eXible connections arranged on guide-pulleys 6, located at the top of the window-f rame and adapted to cause the lower sash and the screen to move simultaneously in opposite directions. When the lower sash is raised, the screen will be automatically lowered, and when the said lower sash is lowered the screen will be automatically raised. The guide-pulleys may be arranged in any suitable rnanner, but are preferably located at opposite sides of the window, as indicated in Fig. 1 of the drawings.

The cords 5 are provided at their lower ends with hooks 5a, adapted to engage either eyes 5b or 5C, mounted, respectively, at the top of the lower sash and on the sides of the window-frame, as clearly illustrated in Fig. 2 of the accompanying drawings. By this construction the lower or outer ends of the cords may be detached from Athe lowersash in winter to relieve the said sash of the weight of the screen when the latter is not in use, and by engaging the hoolisrof the cords with the eyes 5c of the window-frame the screen will be maintained in its elevated position at the top of the window-frame and the lower sash will move independently of the same.

The vertical guides, which are hollow and which are constructed of sheet metal, are intei-posed between the upper and lower sashes and form the parting strips for the same, and each guide is approximately rectangular in cross-section and is provided with sides 7 and 8, arranged as shown in Fig. 3. The rear side 8 has its edge bent at right angles to form a flange 9, and the other side has its longitudinal edge bent inward and folded at its inner faceu to provide a reinforced bearing portion 10. The fiange 9 and the bearing portion 10 extend the entire length of the guide, and they are spaced apart to receive the screen.

`The screen, which consists of a sheet of screen material and a metallic frame, is provided at the bottom of the latter with a centrally-arranged opening 12, located opposite the sash-fastener 13 when the screen is raised and adapted to be covered by an automatically-operating slide 14, consisting of a vertically-movable plate slidngly mounted on the screen, as clearly illustrated in Figs. 4 and 5 of the accompanying drawings. The vertically-movable slide is provided with upper and lower flanges 15 and 16, extending toward the interior. ofthe room, and the upper flange is arranged to be engaged by the top of the lower sash, as clearly illustrated in Fig. 2 of the accompanying drawings, whereby the opening 12 will be automatically uncovered when the screen is raised. The ver- IOO - vent the ingress of insects.

tieally-movable slide depends below the lower edge of the vertically-movable screen when the latter is arranged as illustrated in Fig. 2 of the accompanying drawings', and when the screen is lowered the depending slide will en- `gage the bottom of the window-frame and automatically cover the opening 12 to pre- The slide is secured to the lower 'portion of the screen by means of a horizontal plate 17, secured at its ends tothe frame of the screen and offset therefrom to provide the necessary space or way for the slide. The plate 17 is provided withahorizontally-projecting flange 18, forming a grip and adapted to be readily grasped b y the operator when it is desired to raise the screen without lowering the sash 4.

It will be seen that the screen is sim ple and comparatively' inexpensive in construction, that it is automatic in its operation, and that the opening of the screen is automatically covered and uncovered when lthe lower sash is rai-sed and lowered. Furthermore, it will be apparent that the screen will not interfere with the use of a sash-fastener and that when the screen is raised the sashes may be locked and drawn tightly together to exclude air.

What is claimed is- 1. In a device of the class described, the combination with a Windowhaving upper and lower sashes and provided with a sash-fastener, of a screen connected with one of the sashes and adapted to be raised and lowered by the same and `provided. with an opening adapted to be arranged opposite the sashfastener to permit the sashes to be locked, and an automatically-operating slide arranged to cover and uncover the opening of the screen,

substantially as described.

2. In a device of the class described, the

lower sashes and provided with a. sash-fastener, of a vertically-movable screen provided tener, of a vertically-movable screen provided with an opening and adapted to be arranged opposite the sash-fastener, a plate secured to the screen and spaced therefrom to i form a Way and provided with a iiange, and the automatically-operating slide arranged in the said way and provided with upper and lower flanges and adapted to. cover and uncover the said opening, substantially as described.

4. In a device of the class described, the combination with a window having upper and lower sashes and provided at the top with guide-pulleys and a sash-fastener, of a vertically-movable screen provided with an openl ing, cords arranged on the guide-pulleys and connected with thescreen and with the lower sash, and a slide mounted on the screen and arranged to cover and uncover. an opening thereof, substantially as and for the purpose l described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

JOHNQB. SIMMONS.
