ADJUSTABLE FLY-SCREEN AND SHADE.

Specification of Iietters Patent.

Patented Oct. 29, 1912.

Application filed January 27,1912; Serial No. 673,763.

' had to the accompanying drawings.

This invention comprehends certain new and useful improvements in screens and shades, and the invention has for its primary object an improved construction of a fly screen and shade which may be easily mounted in a window frame, the screen being extended automatically as the window is raised and automatically rolled up as the window is lowered, whereby the space between the lower edge of the window and the window sill will be at all times properly shaded and protected from the entrance of flies, mosquitoes or similar insects.

The invention has for a further object a screen and shade of this character which is laterally adjustable so that it may fit windows of different widths, the parts being so :onstructed and arranged that they can be cheaply manufactured and readily assembled and easily adjusted. And the invention further aims to generally improve this class of devices and to render them more useful and commercially desirable.

l/Vith these and other objects in view as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of parts that I shall hereinafter more fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a face view of a portion of a window equipped with my improved fly screen and shade. Fig. 2 is a transverse sectional view through the automatically winding roller of the device. F igs. 3 and 4: are views of the roller gudgeons to which the winding spring is attached at its ends. Fig. 5 is a detail perspective view of the casing which is designed to receive the roller and the wound up port-ion of the shade and screen so as to protect the working parts. Fig. .6 is a longitudinal sectional view of the roller and a portion of the casing or receivertherefor, parts being shown broken away and other parts in side eleva tion. Fig. 7 is a detail view of the holding device for the elatively free end of the screen or shade. Fig. 8 is an enlarged fragmentary sectional view thereof. Fig. 9 is a transverse sectional View on line 99 of Fig. 7. Fig. 10 is a detail perspective View of one of the gudgeon holding plates, and

Fig. 11 is a transverse sectional view on line 11-11 of Fig. 7.

Corresponding and like parts are referred to in the following description and designated in the accompanying drawings by like reference characters.

In carrying out my invention, a casing 1 is mounted in the window frame, being secured to the lower end thereof by brackets 42 or the like, said casing being constructed of telescopic substantially cylindrical sections split at one side to form a slot 2 extending transversely of the window frame. The edges in the split portion of the" outermost section of this telescopic tubular casing 1 are turned inwardly as best illustrated in Fig. 5 and as indicated at 40' to engage the corresponding edges of the other sec: tion, whereby the two sections will be at all times, held in proper relation to each other as regards the slot 2, so that they may be easily adjusted before being secured permanently in place. Mounted within the casing 1 is a spring roller which is constructed in sections designated 3 and 1, respectively, telescopically mounted in rela tion to each other. The section 4: is tubular as best illustrated in Fig. 6 and receives the reduced tubular stem 5 of the section 3, the stem 5 being formed with a longitudinal rib 25 which works within a corresponding groove' formed in the section 4, so that the two parts or sections of the roller will be at all times, held from turning one relative to the other. The roller spring 14 is mounted within these two sections 3 and 4 and extends entirely therethrough as shown, the

ends of said spring being respectively connected to gudgeons designated 43 and 41, said gudgeons being mounted in the usual manner to shade roller udgeons in plates secured to the window frame, one of said platesbeing designated 4.4 and shown in detail in Fig. 10.

The holding device -17. embodies a bar as which is formed at each end with a longitudinal bore or recess 49, expansion springs 50 being mounted in said recesses and pressing outwardly upon stems 51 that are provided at their outer ends with blocks 52 adapted to fit 1n the sash receiving grooves of the window frame, whereby the holding device will adapt itself to Window frames.

of different widths. The bar 48 is formed with two longitudinally extending grooves 6 and in these grooves wires 45 are connected attheir ends by studs 46 or similar fasten. ingdevices. Each section or strip of the fly screen and shade proper (21 and 22) is loopedaround one end of the bar 48 and is formed at its inner side with a hem by sides of the window frame throughout their which it is adjustably mounted upon one of the wires or cords {15. It will thus be understood thatthe outer side edges of the strips 21 and 22 maybe caused to-snugly fit the length and to be adjusted laterally, either in.-

Ward or outward, according as the roller is extended or contracted in length. In order to. detachably connect the holding device to the window, I have shown in the present instance, a tab 7 which is formed w1th a slot by which it is adaptedto engage a stud 8 or the likesecured to the bottom of the window, as best illustrated in Fig. 1.

It is to be understood that those parts of applicants device whichare directly secured frame and the strips or sections 21 and 22 extended laterally to the required extent, the tab '7 is secured to the stud 8, and thereafter, .i-nthe raising and lowering of the window, the fly screen andshade 'will be automatically extended or withdrawn into the casing 1. Thus the space between the lower edge of the, window and the window sill will at all times, be properly screened and protected from ingress of flies, m'osquitoes or other insects, while at the same time, when the window is lowered, the screen will beentirely out of the way and V will not have to be removed as is the case with the ordinary screens heretofore employed. I

While the accompanyingdrawings illus trate what I believe to be the preferred em- I bodiment of my invention, it is to be under stood that the invention is not limited thereto, but that various changes may be made in v the construction, arrangement and pro portions of the parts without departing from the scope of the invention as defined in th appended claims.

Having thus described my invention, I claim: l

1. A device of the character described, .including a'roller, a screen mounted thereon and constructed'in separate strips adapted to overlap at their inner edges, a bar arranged for attachment to a window,- and longitudinally extending -wires secured to said bar, the ends of the strips at their inner edgesbeing. lapped upon said wires for the purpose specified.

2. A device of the class described, including a telescopic casing adapted to be -secured to a window frame, an extensible roller mounted in said casing, a shade and screen secured to said roller and-constructed in separate strips, and means for'connecting one edge of said screen to a window, said means embodying a bar, wires secured to said bar and extending longitudinally thereof, the strips being movably connected to said wires, and a device carried by said garfor detachable connection to said win- 3. A. device of the character described, including a'roller, a screen mounted thereon and constructed in separate strips adapted to overlap at their inner edges, a bar arranged for attachment to a window, and.

longitudinally extending wires secured to said bar, the ends of the strips at their in-' ner edges being looped upon said wires and at their outer edges encircling said bar.

4. A device of the character described, including a roller, a screen constructed in separate strips secured to one end of said roller, a bar arranged for attachment to a Window and formed with longitudinal grooves, and wires connected to said bar and extending along the grooves, the strips at oneend being looped at their outer edges over the bar and being looped at their inner edges over the wires,- as and for the purposes set forth.

5. A device of the character described, including a roller, a laterally extensible screen mounted thereon, and a bar to which one end of the screen is connected, the bar being arranged for attachment to a window and formed .at each end with a longitudinal opening, expansion springs mounted in said openings, and stems mounted in said openings and engaging said springs, the stems being provided at their outer *ends with blocks for the purposes specified.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
