4 Application filed April 2, 1881. (No model.) i

To all whom it may concern:

Be it known that I, RICHARD G. LUDLOW,

- a citizen of the United States, resident-at St.

Louis and State of Missouri, have invented certain new and useful Improvements in Fly- Screens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a front view of my device. Fig. 2 is a vertical section, and Fig. 3 is a horizontal section. This invention relates to improvements in screens for windows, known as fly-screens, and it consists in the improved features of construction and combination hereinafter fully de scribed, and particularly pointed out in the claim.-

Heretofore much annoyance has been expeframe having the usual top and bottom sashes, B O.

Secured to the inside strips, D D are the rails E E, somewhat longer than the space made when the lower sash is raised. These rails have the tongues c e, and are divided into upper and lower portions, a and b, by the outwardly, downward, oblique kerfs, c, the lower portions, 1) b, beiu g rigidly affixed to the strips, and the upper portions, a a, pivoted at d 01, these pivots being-at such points that when the lower sash is up and the upper portions turned out at right angles they will strike the the bottom rail of the sash.

. F is the screen, having in its side edges the grooves f f fitting the tongues e e, and at its bottom, on the inside, the groove f, which may be a simple groove or formed by an ornamental molding.

In putting the screen in, the lower sash is raised and the pivoted portions of the-side rails turned with their upper ends inward. The screen is taken with its outer side up, and with its lower side forward is slipped onto these upper portions, the tongues fitting the grooves. It is slid on for nearly the length of these upper portions, and then is' swung up, these turning down to their places when the screen is lowered to place. To take the screen out the operation is reversed.

The groove at the bottom facilitates lifting without the trouble of hunting for the lift, and is equally applicable to a window-sash.

When it is desired to have the lower part of the window open without taking the screen away the latter is pulled up, turned down at right angles, and its lower end caught under the sash, where its weight will hold it.

The screen may be placed on the outside, if desired.

A pivoted side strip, in combination with a sash having grooved edges, is not broadly new, and protection is asked only for the improved construction hereinafter claimed.

In a fiy-screen for windows, the rails E, having the tongues e, and located below the upper sash-frame, the portion a being pivoted to the window-frame, and the portion 1) being rigidly secured thereto,in combination with the screen F, having grooved edges to receive the tongues 0, whereby the screen may be drawn up and placed in a horizontal position without removing it from the rails, substantially as shown and described. r

In testimony whereof I afliX my signature in presence of two Witnesses.
