ADJUSTABLE scanner.

Application. filed October 6, 1922.

To all whom it may concern:

Be it known that l, ALFRED V7. EMnnsoN, a citizen of the United States, residing at Steuben, in the county of l vashington, State of l /laine, have invented certain new and useful Improvements in Adjustable Screens; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in screens and particularly to window screens.

One object of the invention is to provide a window screen which is adjustable transversely of the window, and which affords no opening through which insects may pass, as is the case with the ordinary two sectionedjustable screens now on the market.

Another object is to provide an adjustable screen of this character which is capable of being easily and quickly adjusted to fit windows of different widths, and which can be easily and quickly collapsed to its minimum width, without injury to the screen fabric.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is an elevation of the screen as viewed from one side and in collapsed position.

Figure 2 is an elevation as viewed from the opposite side, the screen being extended, and partly broken.

Figure 3 is an enlarged transverse sectional view on the line 3 3 of Figure 2.

Figure 4: is a longitudinal sectional view on the line H of Figure 2.

Referring particularly to the accompanying drawing A and B represent the two sliding frame sections of the screen, which include, respectively, the longitudinal side bars 10 and 10 and the outer transverse connecting bar 11 and 11. Secured to the frame section A is a strip of screen wire fabric 12, one end of which extends to a considerable distance beyond the open end of the frame, for a purpose which will presently appear herein. The longitudinal edges of the screen fabric are held in place on the frame section Serial No. 592,772.

A, by means of the batten strips 13, the same extending outwardly from the faces of the tion B. Secured to the outer end portions of the battens 13, and to the bars 10 of the section A, are the retaining straps 15. which maintain the bars 10 of the section B within the confines of the strips M- and the battens 13, as the sections A and B are moved longitudinally with respect to each other.

On the other wider faces of the bars 10 of the section B- which are longitudinally rabbeted, as seen at 12 there are secured the longitudinally extending metal plates 16, be tween which and the adjacent wider faces of the bars 10, the portions of the longer marginal edges of the screen fabric, beyond the open end of the frame section A, slide.

Mounted on the end portions of the wider face of the transverse bar 11, of the section B, opposite the adjacent ends of the metal plates 16, are the outstanding apertured brackets 17 in which are rotatably supported the ends of the roller 18. Secured to this roller is the shorter marginal edge of the outer end of the screen fabric 12, and on this roller the said projecting portion of the screen fabric is arranged to be rolled. Curved housings 19 are secured to the brackets 17, to cover the adjacent ends of the roller 18. It will be noted that the outer ends of the metal plates 16 are disposed close to the ends of the cross bar 11 of the section B, so that as the screen fabric passes from beneath the ends of the metal plates,

said bar, and is secured Within a licr't 2b,

formed in the adjacent end ot the side bar {iethen the pull of the ends of the cords. due

i to the force exerted thereagainst by tuc ends of the bars 10 of the section A, will cause the ends ot the cords to turn the roller 28 the opposite direction, with the result tiat the said cord ends will be unnound from the roller and the screen fabric wound thereon.

By this construction the screen is capable of adjustment to any degree without permitting any opening for insects, the fabric being continuous from end to end.

What is claimed is:

1. An adjustable Window screen comprising a pair of slidable sections, ascreen carrying roller on one of the sections, the side rails of the roller section having openings adjacent their ends, rollers mounted in the openings, and a cord connected to the outer end of each of the side rails of the other section and to one end of the screen carry" ing roller and engaged around the said rollers Within the respective openings of the corresponding rail of the roller carrying section.

2. An adjustable Window screen comprising a pair of slidable sections having engaged side rails, the rails of one section being channeled to receive the rails of the other section, the rails of the other section having openings adjacent the opposite ends thereof, the last-named section having a roller mounted thereon and carryinq a screen fabric, strips secured to the side rails of the roller carrying section and cooperating therewith to maintain the longer marginal edges of the screen slidably therebetween, grooved rollers in the openings of the said rails, and a cord connected to the outer end of each of the rails of the first section extending through each of the openings thereof, around the grooved rollers and being connected to and Wound on an end ot the screen fabric roller.

In testimony whereof, I allix my signa ture, in the presence of tWo Witnesses.

ALFRED W. EMERSON.
