Specification of Letters Patent.

Patented Mar. 9, 119th.

Application filed May 4, 1914. Serial No. 836,242.

To all whom it may concern Be it known that I, WALTER S. BRIDGES, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Window-Screens, of which the following is a specification.

This invention relates to window screens having a collapsible frame, and its object is to provide a frame of very simple construction to which the netting or screen fabric can be readily secured, and which frame is adjustable to properly fit in the Window frame. This object is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawing, in which Figure 1 is an elevation of the screen; Fig. 2 is a perspective view of the screen frame parts before they are assembled, and Figs. 3 and 4: are perspective views showing devices for clamping the screen frame parts in assembled position.

Referring specifically to the drawing, the screen frame comprises two end bars 5 having projecting pins or other suitable fasteners 6 on one of their faces to secure the ends of the netting or screen fabric 7. The bars are connected by top and bottom rails which are in sections. The two sections of the top rails are indicated at 8 and 9, respectively, and those of the bottom rail at 10 and 11, respectively. The section 8 is pivoted at 12 to the upper end of one of the bars 5, and the section 9 is pivoted at 13 to the upper end of the other bar 5. The

sections

10 and 11 are connected in a like manner to the lower ends of the bars 5.

To apply the netting 7 to the frame, the rail sections 8 and 9 are swung inward to cross each other, and the

rail sections

10 and 11 are also placed in crossed relation, and the bars 5 are brought together a distance to allow the ends of the netting to be fastened thereto by the pins 6. Clamps are now applied to the intersecting portions of the rails, and the rail sections are swung outward to come into parallelism alongside each other, whereby the bars 5 are spread and the netting 7 is stretched tight therebetween. The rail sections are locked in the last described position by tightening up clamping members each of which comprises a small metal plate which is bent to form a yoke, the branches 1 1 of which straddle the rall sections, one of the yoke branches carrylng a set screw 15 which is adapted to be screwed against one of the rail sections, whereupon the sections are clamped together and securely held in parallelism. A further means for locking the sections in parallelism comprises a sleeve 16 which is slidably mounted on one of the sections and is slipped over the lapping end of the adjacent section. To remove the netting 7, it is necessary only to disengage the clamping devices of the top and bottom rails, whereupon said rails may be swung inward to bring the end bars 5 closer together. The netting may then be removed, and if worn it can readily be replaced by a new sheet. The end bars may be made of wood, and the top and bottom bars are preferably thin metal strips.

The structure herein described provides a very cheap and simple screen frame which can be easily mounted in place or removed from the window frame. The end bars when expanded as described to stretch the netting are properly seated in the jamb grooves of the window frame.

I claim:

1. A screen frame comprising spaced end bars, sectional top and bottom rails, the sections of said rails being pivoted to the respective end bars, and free to be placed in crossed relation to bring the end bars toward each other, and to be placed side by side in parallelism to space the end bars farther apart, means for clamping the sections in the last-mentioned position, and means for securing a screen fabric to the end bars.

2. A screen frame comprising spaced end bars, sectional top and bottom rails, the sections of said rails being pivoted to the respective end bars, and free to be placed in crossed relation to bring the end bars toward each other, and to be placed side by side in parallelism to space the end bars farther apart, a clamping yoke straddling the sections, a set screw carried by the yoke for clamping the sections together in the lastmentioned position, and means for securing a screen fabric to the end bars.

In testimony whereof I aflix my signature in presence of two witnesses.

WALTER S. BRIDGES.
