ATTD R N EYB Patented July 18, 1950 [JN-IrenN smv-Es Pff oet-*FICE My'presen-t inventionn relatsifto an improved window screen and more particularly to`=vthe roll er supports'l for thescreen aridthe meansije'mployed fori retainingn the screen Lin adjusted-positiorr. The screenA of my invention is'a'dapted for mounting exterior of the window sashes and depends from rollers located near the upper extent of the sashes. The screen so mounted may be vertically raised and lowered and the novel means employed hereinafter referred to will secure the screen in any desired position.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention according to the best mode I have thus far devised but it will be understood that various changes and alterations may be made in the exemplified structure Within the scope of the appended claims.

In the drawings:

Figure 1 is a front elevational view of the screen of my invention shown in lowered position and mounted on a conventional window frame.

Figure 2 is a vertical sectional view through the window frame.

Figure 3 is a plan view of the idler roller.

Figure 4 is a sectional view at line 4-4 of Figure 3.

Figure 5 is a sectional view at line 5-5 of Figure 3.

Figure 6 is a longitudinal sectional view of the screen roller.

Figure 7 is a sectional view at line 1-1 of Figure 6.

Figure a is a sectional view at line 8 8 of Figure '1.

Figure 9 is a perspective view of the magnet employed to hold the screen in adjusted position.

Figure 10 is a perspective view of the end collar for the screen roller.

Figure 11 is a perspective view of the resilient bracket.

Figure 12 is a detail view of the screen catch.

Figure 13 is a perspective view thereof.

Figure 14 is a perspective view of the reel.

Figure 15 is a partial view in perspective of the screen roller.

Figure 16 is a perspective view of a modified catch.

Referring now to the drawings in detail I have illustrated a conventional'window frame 2 having a sill 4 and provided with an upper sash 6 and lower sash 8. The screen l0 is fashioned of conventional material as metal or plastic and the lower free end of the screen is provided with a stiiening rod I2.

2 In; order` to' permit'the close relation ofi the upper portion ofthe Vscreen with the window frame to? prevententra'nce of bugs and flies, I employtheidleirrmler I 4' having end: pinsE l 6,' onev pin l ybeing supported fixed relation'inv the" bracket I'8V through the flange 20 and hole 22, the bracket being secured to the frame by screws 24.

The other end pin is detachably secured in the bracket 26 having a spring arm 28 and an opening 30, and screws 32 are provided to secure the bracket on theframe opposite the bracket IB. The roller carried on these brackets supports the screen thereon.

The screen roller comprises sections 34 and 38 with the end of the screen material therebetween and secured therein by screws 38. One end of the roller is reduced and receives thereon the collar 40 having a split ring 42, and a stub shaft 44 is carried thereby. The shaft extends into the bracket 46 secured to the frame and within the bracket I have located a magnet 48 substantally cylindrical in shape and formed with a diametrical slot 5l] forming separated poles. A washer 52 separates the magnet from the collar 40 and it will be apparent that the magnetic pull of the magnet will attract the -collar and releasably resist rotation of the roller.

The roller of course may be rotated by manual pressure but the magnet will secure the roller in adjusted position.

On the opposite end of the roller sections I have fashioned the reel 54 and a stub shaft 56 is secured in the bracket 58 through the opening 62 in the resilient spring arm 60, the bracket being secured to the frame by screws 68. A guide arm 64 on the bracket is formed with a slot 66 therethrough guiding the cable 'I0 from the reel and through the eye 'H to the stiffening bar l2.

The screen is secured in close relation to the Window frame by means of the catches 'l2' formed of preferably metal strips looped as at 14 and secured by screws 16. In Figure 16 I also provide these catches with a washer 18 in which case the screen overlaps the window frame.

From the above description of the construction and operation of the screen of my invention it will be apparent that the screen will be durable and yet will be easily and with facility raised and lowered. The novel arrangement for securing the roller and screen in adjusted position will not be subject to wear as are springs, and the screen will automatically be secured in position whenever the manual pressure stops.

With the use of the idler roller the screen will always be maintained in close proximity to the window frame as it otherwise would not be if the screen roller were mounted directly above the vertical plane of the screen and the diameter of the screen rolled, would diminish or increase as the screen was adjusted.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination with a flexible window screen and its roller, a bracket mounting for the roller, and magnetic means in the bracket releasably securing the roller in adjusted position.

2. The combination with a window screen and its roller, of a supporting bracket for the roller mounted on the frame of the window, a magnet in the bracket having a diametrical slot forming spaced poles continually -pulling the roller against the magnet whereby the roller is frictionally secured in adjusted position.

3. The combination with a window screen and its roller, of a metal cap'for the roller, a supporting bracket for the roller mounted `on the window frame, a magnet in the bracket having a diametrical slot forming spaced poles continually pulling on the roller cap and holding same NATHAN HAMNIER.
