WINDOW-SCREEN.

Specification of Letters Patent.

Patented June 10, 1919.

Application led November 5, 1917, Serial No. 200,329. Renewed May 5, 1919. Serial No. 295,025.

To all whom it may concern:

Be it known that I, JOSEPHA Z. CoLLET'rn, Jr., a citizen of vthe United States` of America, residing at Fitchburg, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Window-Screens, of which the following is a specification.

This invention relatesto certain new and useful improvements in window screens and relates particularly to window screens of the sliding type.

It is the especial object of the present invention to so construct a screen of the above type as to present a most efficient device of its kind and which is durable and simple in plan of construction.

Another object is to provide a renewable metal bound screen section which'is capable of being quickly attached to and removed from the sliding frame which carries the same.

A further object is to provide novel means whereby the window sashes are locked against being lowered and the screen locked against being raised from the outside of the dwelling equipped with the same.

A still further object iS to provide guideways for the screen and means carried by the screen and engaging one of the guideways to lock the screen in lowered position or to lock the Same in adjusted raised p0- sitions.

Vith the above general objects in view and others that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In the accompanying drawings forming part of this specification and in which like reference characters indicate similar parts throughout the severalviews;

Figure l is an inside sectional view o-f the lower portion of a window with the present invention in position therein and taken on line I-I of Fig. 2.

Fig. 2 is a vertical sectional view of Fig. 1 taken on line II-II thereof.

Fig. 3 is an enlarged fragmentary perspective view of portions of one of the guideways.

Fig. 4 is an enlarged perspective view of Fig. 5 is an enlarged perspective view `of the lock carried by the upper end of the screen.

Fig. 6 is a fragmentary perspective view of one of the upper corner portions of the screen with the removable transverse strip removed, and

Fig. 7 is a fragmentary perspective view of one end of the upper removable strip.

Referring more in detail to the drawings, the invention embodies a rectangular screen strip 1 whose edges are provided with a metal binding 2. The screen strip 1 is carried by a Sliding frame composed of side strips 3 and 4, a lower end'strip 5 and a ivemovable upper end strip 6. The inner edges of the strips 3, 4, 5 and 6 are provided with longitudinal grooves 7 8 and 9 and the upper ends of strips 3 and 4 are each bifurcated to provide two spaced legs 10 and 11 between which is adapted to be secured one of the reduced ends 12 of the strip 6 by any suitable means, such as the screws 13 shown by dotted lines in-Fig. 1 which enter the apertures 14 and 15 of the bar 3 or 4 and the bar 6 respectively. In assembling the device, upper bar. 6 is removed, the metal bound screen section 1 slid downwardly into position in the grooves and the bar 6 secured in position, and it will be apparent that this construction provides an inexpensive, Simple and durable means for renewing the screen section when damaged or worn from extended use.

In order to guide the screen in its vertical sliding movements, I provide channel bars 16 andr 17 which have their transverse portions 18 Secured to the window frame 20 by means of screws 19.

The Screen is retained in position, as shown in Fig. 2, outwardly of the sashcs 21 and 22, and in order to prevent the sash 21 from being lowered from the outside, I provide a lock 23 which is detachably attached to the upper portion of the screen by means of the screws 24 and keyhole slots 25. This lock is preferably formed of an elongated metal strip, one of whose ends are bent at right angles to provide a lip 26 which engages the under face of the lower rail of the sash 21 as shown in Figs. l and 2 and the other end of the lock 23 is slitted to produce a narrow strip which is curved and bent outwardly to provide a handle 27.

In order to prevent the screen from being raised from the outside and to lock the same in adjusted raised positions, I cutaway a portion of the lower end of the guide 17 to provide a shoulder 28 under which engages the outwardly bent portion 29 of a lock 30 which is pivoted for lateral swinging movement to thelower portion of the screen by means of a screw 31. The lock 30 is preferably formed with a handle 32 similar to the handle 27 of lock 23 and in order to add to the eiiciency of the lock the portion 29 thereof is extended upwardly as at 33 to embrace the guide. When it is desired to raise the screen, the lock 30 is swung out of engagement with the shoulder 28 as indicated by dotted lines in Fig. l and the handle 34 grasped to raise the screen. The screen may be locked in adjusted raised positions by swinging the lock 30 into either one of the notches 35 and 36 of the guide 17, as desired.'

While the form of the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is iievertheless to be understood that various forms, modifications and arrangements of vCopies of this patent may be obtained for the parts may be made without departing from the spirit and scope of the invention as claimed.

What I claim as new is l. A window screen including a rectangular'grooved fram'ehaving a removable end strip, and a metal bound screen section removably slidably positioned in the grooves of said frame.

2. The combination with a sliding window screen of a notched guide-Way therefor and a pivoted lock attached to the lower end of the screen and removably engaging in the' notches .of the guide-way to lock the screen in lowered position Vor in adjusted raised positions.

3. A locking member adapted to be attached to the upper portion of a sliding window screen to prevent the upper sash ofa window from being loweredhi'rom the outside of a dwelling comprising a strip of metal having key-hole slots Vtherein and having one of its ends bent at right angles to engage the under face of the lower rail of a window sash and having its other end slitted to produce a narrow strip which is curved and bent outwardly to provide a handle.

In testimony whereof I aiiX my signature.
