ASSIGNOR TO AMERICAN: ROLLING- A CORPORATION OF ILLINOIS- ROLLING SCREEN Application filed J'n'ne 7, 1929. Serial No. 369,042.

This invention relates to a roller screenand consists in certain improvements for latching the screen in its lowered position for releasing and guiding the same and for deadening the sound in the roller housing arising from the contact of the screen with a side wall of the housing.

The invention comprises the novel structure and combination of parts hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawing which illustrates a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the different views V.

Figure l is an enlarged transverse sectional view thru a window equipped with a screen involving this invention.

Figure 2 is an enlarged fragmentary plan view at the lower corner of the window.

Figure 3 is an enlarged fragmentary horizontal sectional view taken upon the line III-III of Figure 1.

Figure 4 is an enlarged sectional view taken upon the line IVIV of Figure 3.

As shown on the drawing:

In the drawing, there is shown an elongated rectangular sheet metal housing 1 which is located above the window and which is provided with an opening or throat 2 adjacent the front vertical wall 1a. This wall is turned back along its lower edge to form a channel or groove 2a which extends longitudinally of the housing. A roller 3 upon which the screen 4 is wound is supported within the housing 1, and a sound deadening medium in the form of a fibrous board 5a is positioned against the front wall with its lower margin seated in the groove 2a, with the result that the screen in passing thru the throat will strike the sound deadening medium instead of the rear metal wall 1a and thus eliminate the objectionable noise that has heretofore existed. WVhile the foregoing construction is to be preferred, it will be obvious from the disclosure in the drawing that the inwardly spaced wall of the groove 2a, when the fibrous board 5a is removed, will tend to hold the screen away from the front wall and prevent the screen from slapping thereagainst.

Asthe screen is raised eral margins thereof travel in suitable guideways 5 formed in the sides of the window frame. These guideways are preferably formed by sheet metal members 6 and of angular formation. These angular members have flanges with beaded edges that form: the parallel walls of the guidewaysand over lapping flanges that protrude to one side of the guideways and that are embedded in the window frame. A substantially U=shaped metal sheath 7 is inserted in eachguideway. Each sheath has a restricted throat. 7 a for'a purpose that will later appear 7 The screen is provided at its lower margin with a rail or hand hold generally denoted by the reference numeral 8.v vThis railcon sists of a substantially right-angled plate 9 having a vertical flange 10 and a horizontal flange 11 provided with a returned: bent nether lip 12 for retaining a cushioning pad 13, adapted. for resting upon the window sill, and a second angular plate having a vertical flange 14 adjacent the vertical flange: 10.: of the plate 9. and ahorizontal flange 1-5. overlapping'a portion of the: horizontal flange 11 of the'plate 9. The vertical flanges of these plates are stamped with beadsto form a cylindricalpassage 16 a suitable distance from the top thereof. The lower. margin. of

the screen is clamped between these verticalv flanges of the hand hold platesand a rod 17 attached to the lower margin of the screen is located in the cylindrical passage 1:6: and

It'lhillgfirmly anchors the screen to the'hand It will be noted that the rail or hand hold does not extend to the lateralmargins of'the screen. Tobind the margins of-the screen at the hand hold, a plate 18 (:Fig. isattached to the rear face of the hand hold adjacent each end and this plate 1 8 is folded "over the adjacent margin of the screen as indicated. at 19. V

A slidable friction device is attached. to each end. of the hand hold and extends into the adjacent guideway. Each friction device consists .of a: plate 20 having a screw 21a and slot. 22 connection with the hand hold. Each slidable plate 20carries a leaf andlowered,the latspring 21. Beyond the hand hold, the plate 20 is bent inwardly as indicated at 22a in order to operate freely in the throat of the guideway. The leaf spring 21 may be attached to the plate 20 in various ways. In the present instance, the plate 20 has an upper bent over portion 20a, and the leaf spring 21 has an arm that extends upwardly from under the plate 20 and extends under the bent over portion 20a. To hold the arm of the leaf spring 21 adjacent the front face of the plate 20, another plate 23 may be superposed over the arm and riveted'or secured to the plate 20. The leaf spring 21 is designed to press against an adjacent wall of the guideway in which it is located and exert suflicient friction to maintain the screen in adjusted position. The front walls of the guideways are preferably cut away adjacent the bottom thereof as indicated at 24 (Fig. 2) to allow the leaf springs 21 to automatically urge the lower part of the screen outwardly to bring the upper edge of the plate 20 under the shoulder formed by the cut out portion, thus securely latching the screen in its lowermost position. When it is desired to elevate the screen from its lowermost position, it is necessary to press the screen inwardly. For this purpose, the plates 20 are provided with upwardly projecting finger pieces 25 against which the pressure may be exerted without damaging the screen.

From the foregoing, it will be obvious that the improvements herein described facilitate the use and operation of roller screens, and eliminate the noise and allow the same tobe more speedily operated.

I am aware that many changes may be made, and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

1. In a roller screen device including a housing having a throat adjacent one wall, a roller in said housing, and a screen on said roller passing thru said throat; a sound deadening medium on said wall adjacent said throat.

2. In a roller screen housing having a throat adjacent one wall for the passage of a screen therethrough sound deadening means associated with said wall adjacent said throat.

8. In a roller screen device including a housing having a throat adjacent one wall for the passage of a screen therethrough; a fibrous member associated with said wall adjacent said throat for deadening the sound resulting from the operation of the screen.

4. In a roller screen device including a housing having a throat adjacent one wall,

a roller in said housing, and a screen on said roller passing through said throat; a member of sound deadening material disposed between the screen and said wall to prevent the screen from striking against said wall to create objectionable noise.

5. In a roller screen device including a housing having a throat adjacent one wall for the passage of a screen therethrough; a channel formed at the lower edge of said wall, and a member of sound deadening material disposed on the inner surface of said wall and having its lower margin seated in said channel.

In testimony whereof I have hereunto subscribed my name at Chicago, Cook County, Illinois.
