Application filed July 18,

T0 allwkom it may concern:

Be it known that I, JAMns G. ALLEN, a citizen of the United States of A1nerica,residin at Detroit, in thefcounty of Wayne and Qtate of Michigam'have invented certain new and useful Improvements in VVin- (low Screens, of which the following is a v specification, reference being had therein to the accompanying drawings.

In my Patent No. 1,214,494, granted Feb. 6, 1917, there is disclosed a wlndow screen having a collapsible or foldable frame which permits of the screen being rolled whereby the entire structure will occupy a comparatively small space when not 1n use.

This invention relates to a rigid window screen frame, in contradist'inction to the collapsible frame of. my prior patent, and this invention aims to furnish such a frame;-with novel means for detachably retaining it within the window frame, so that the screen may be easily and quickly removed, particu larly during inclement weather or during winter.

My invention further aims to provlde a window frame screen thatmay be adjusted similar to a sash and locked in a lowered or closed position.

The construction entering into my invention will be hereinafter described and then claimed, and reference will now be had to the drawings, wherein- Figure 1 is an elevation of the inner side of a portion of a window frame provided with a screen in accordance with this invention-.

Fig. 2 is a vertical cross sectional view taken on the line IIII of Fig. 1;

Fig. 3 is a front elevation of a window screen;

Fig. 4 is a cross sectional view of the frame taken on the line IV-IV of Fig. 3;

Fig. 5 is an enlarged cross sectional view taken on the line V-V of Fig. 1, and

Fig. 6 is an enlarged horizontal sectional view taken on the line VI-VI of Fig. 1;

In the drawing, there is shown a portion of a window having a sill 1, stiles 2, strips 3, and an upper sash 4 having a meeting'ra-il 5. The upper sash 4 is slidable between the strips 3, in the usual manner, and the lower sash has not been shown in order to more clearly show my wirescreen in the window 1921; seen no. 485,482..

lar frame havingside. rails 6 a top railr 'l' and a bottom rail 8, said railsha-ving the ends thereof suitably. joined to provide a rigid frame to which [maybe suitablyconnected the marginal ends of a wire screen 9. This wire screen may be of the usual interwoven wire fabric adapted to exclude flies,

and, other insects, and the edges ofthes'creen.

may be connected to .framefrails bybeads In some :in-

10 or other fastening means. I may be substituted 1 for the stances glass screen 9.

The side rails 6 of tlie screen fr ame are provided with longitudinal recesses 11 to receive sideflanges 12fof channelshaped re taimng members 13, said reta ning members corresponding in length .to the frame rails 6.

The retaining members ;13 may be shiftedon the rails 63 to increase -or[decr'easethe over-Q all width of the screen frame-andfholding the retaining members 13 normally eXtended are flat springs 14a'rranged inthe upper and lower ends of the retaining members and connected to the frame rails 6, asjbest' 1 shown in Fig. '3.

To prevent the retaining members 13 from being completely shiifted off of the'rails 6 and at the same time afford convenient means of retracting the retaining members 13, finger outward movement of the finger pieces 15 and the retaining members connected there The loop or stop portions 1 6 of the 55 finger pieces 15 can be gripped when it is desired to retract the retaining members 13 to remove one or both edges of the Screen fromthe window frame, it 'is through the medium of the retractable retaining mem- 100.

pletely removed from the window frame- Q bers 13 that the wire screen may be com Suitably attached to the opposed strips 3 of the stiles 2 are channel guides 17 which extend from the sill 1 towards the top of the window frame and to a suiiicient height to permit of a wire screen being raised relative to the sill 1. The retaining members 13 are adapted to slide in the channel guides 17 i and to facilitate moving the wire screen the bottom rail 8 has a suitable handle 18,. i

handle 18 and the loop or stop portion 16 of the finger pieces 15' are within the screen frame and will not interfere with the operation of a lower sash within the window frame; a

In order that the window screen may be locked in a lowered position, the retaining members 13, adjacent the lower ends thereof, have apertures 19 adapted toengage studs 20 carried by the channel guides 17.

The retainingmembers 12 will'readily snap into engagement with the studs 20 and said retaining members may be retracted when it is desired to adjust the window screen. Such locking means for the window screen may be used at one or bothsides thereof and throughout the length of the, channel "guides 17 so that the window screen maybe of rubber, felt or a resilient material.

It is thought that the utility of the screen will be apparent without further description, and while in the drawing there is illustrated a preferred embodiment of my inventlon, 1t is to be understood that the structural elements are susceptible of such changes as fall within the scope of the appended claims.

What I claim is l. The combination of a window frame, channel guides therein a screen frame, channel'shaped retaining members slidably carried by said screen frame and slidable in said channel guides, said retaining members having openings adjacent the lower ends thereof, finger pieces attached to flanges of said retaining members adapted for shifting said retaining members to remove said screen frame from said window frame, and studs carried by said channel guides and adapted to extend into the openings of said retaining members.

2. The combination set forth in claim 1, wherein said finger pieces include stops adapted toengage the inner edges of the screen frame and limit the outer movement of the retaining members.

In testimony whereof I afiix my signature in'presenoe of two witnesses.

. JAMES ALLEN.
