A tiorneys Patented July 16, 1940 UNITED STATES mrENTfoFFic 2,207,356 WINDOW soi'mniv Z. John Clifford Gieser, carding ton, Ohio Application December 27, lssilfserial No. 311,176; 4 Claims. Cl.156- -i -39 This invention relates broadly to screens of the type employed particularly for use in con' nection with windows, and more particularly to that type of screen including a web or sheet of flexible foraminous material attached .at one end to a spring roller and equipped at the other end thereof for attachment to a window sash.

Among the objects of the present invention is to provide a screen of this type which may be readily installed and which, generally, is an improvement upon such screens.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is an elevational view illustrating the application of the screen with the window sash in raised position.

Figure 2 is a fragmentary vertical sectional view taken substantially on the line 2-2 of Fig. 1.

Figure 3 is an end elevational view of the screen and housing therefor.

Figure 4 is a fragmentary detail sectional view through the spring-equipped end of the roller, and I Figure 5 is a detail sectional view taken substantially on the line 55 of Fig. 1.

Referring more in detail to the drawings it will be seen that in the preferred embodiment of the invention the same comprises an oblong housing 5 embodying an oblong frame having a top 6, ends I, and a bottom 8; the bottom 8 being in the form of a rectangular plate equipped at opposite ends thereof with flanges 9 to which are riveted or otherwise secured as at the sides 1 of the frame.

Completing the housing there is disposed at the outer side of the frame I an angular wall I I that is integral with the outer longitudinal edge of the plate 8. The wall H extends vertically upwardly from the plate 8 and then is curved inwardly towards the top 6 of the frame, with the upper edge of the wall in intimate contact with the longitudinal edge of the top member 6 of the frame, and may be welded or otherwise positively united therewith as found desirable.

It will be seen that this construction and arrangement provide for openings 12 at opposite sides of the housing whereby access may be had to the screen and the roller therefor.

The sides 1 of the frame portion of the housing are equipped adjacent one vertical edge thereof to receive the pintles of a roller l3 whereby said roller may be easily and quickly mounted in position. I i

As shown in Fig. 14 the roller embodies a core through the medium of a coil spring ll that is convoluted about the-shaft it that extends from one end of the core l4 through one end of the complete roller. The spring ll is suitably anchored to the core l4 and to one end ofthe shaft I6, and the tubular part l3 of the roller is equipped to receive'oneend of the shaft [6 as shown. Thus spring'l'l will, as previously stated, cause the parts of the roller as a unit to rotate relative to the shaft for winding on the roller the web or sheet I8. The web'or sheet I8 is of flexible foraminous material, and at its free end is provided with a reinforcing bar I9.

Bar l9 isprovided with eye-bolts 2t adapted to be engaged with hooks 2| provided on the lower rail of the sliding window sash 22 for detachably connecting the screen with the window sash.

Also mounted in the frame of the housing is a guide roller 23 over which the sheet I8 is trained as clearly shown in Figs. 2 and 3.

In actual practice, the frame portion of the housing 5, and which is slightly longer than the wall ll of said housing, sits on the window sill between the

stops

23, 24, and the entire housing structure is releasably anchored in position through the medium of pointed anchoring lugs 25 that are pivoted to the top 6 of the frame portion of the housing as at 26. The pointed ends of the anchoring prongs 25 bite into the side rails 21 of the window frame and thus serve to properly anchor the housing in position and against the housing being pulled upwardly incidental to a raising of the window sash 22.

' I From the above it will be seen that when the device is properly applied and the screen sheet l8 connected in the manner shown and described to the lower rail of the sliding sash 22, movement of the sash 22 to a raised position will cause the screen web l8 to pay out and thus cover the opening caused by the raising of the Window sash.

Manifestly, as the sash 22 moves downwardly to a closed position the screen web l8 will wind on the roller I3. I

It is thought that a clear understanding of the construction, operation, utility and advantages of a Window screen embodying the features of the present invention will be had without a more detailed description thereof.

Having thusv described the invention what is claimed as new is:

1. In a window screen, an elongated housing member adapted to be positioned on a window sill between the vertical rails of a window frame and equipped with means for engaging such rails to anchor said housing in'place, a roller journaled in said housing, and a screen Web windable on said roller, said web having a free end reinforced and equipped with means for detachably connecting said end to the lower rail of a sliding sash; and said housing comprising a relatively broad flat base plate, a frame rising from said base plate and extending for substantially the full length of said base plate and including a top member, the members of said frame being substantially half the width of said base plate, and a Wall plate extending upwardly from the longitudinal edge of the base plate farthest remote from said frame and having the upper portion thereof biased toward said frame with the upper edge in meeting contact with the top member of said frame.

2. In a portable screen, a base plate having upstanding flanges at opposite ends thereof and extending from about the longitudinal median of said plate to one longitudinal edge of the plate, a frame having top and end members, said end members at the lower ends thereof being secured to said flanges, a spring roller supported between the end members of said frame, a flexible foraminous web windable on said roller, and a wall-forming plate extending from the second longitudinal edge of said base plate to the top member of said frame.

3. In a portable screen, a base plate having upstanding flanges at opposite ends thereof and extending from about thelongitudinal median of said plate to one longitudinal edge of the plate, a frame having top and end members, said end members at the lower ends thereof being secured to said flanges, a spring roller supported between the end members of said frame, a flexible foraminous web windable on said roller, and a wall-forming plate extending from the second longitudinal edge of said base plate to the top member of said frame, and anchoring lugs pivoted at one end thereof to the top member of the frame adjacent opposite ends of said top member.

4. In a portable screen, abase plate having upstanding flanges at opposite ends thereof and extending from about the longitudinal median of said plate to one longitudinal edge of the plate,

a frame having top andend members, said end members at the lower ends thereof being secured to said flanges, a spring roller supported between the end members of saidframe, a flexible: foraminous web windable on said roller, and a wall-forming'plate extending from the second longitudinal edge of said base plate to thetop member of said frame, and anchoring lugs pivoted at one end thereof to the top member of the frame adjacent opposite ends of said top"
