SCREEN, CURTAIN, AND THE LIKE.

Specification of Letters Patent.

Patented Sept. 19, 1916.

Original application filed September 10, 1913, Serial No. 789,036. Divided and this application filed March 22, 1915. Serial No. 16,034.

fined to a definite plane of movement inwinding on or being unwound from their rollers designed to improve its appearance, increase its efliciency, save space in a window opening or wherever else it may require to be used, facilitate the operation of the screen or curtain and give added strength and durability. T

The present application is a division of my application on which issued Letters Patent No. 1,138,668.

The invention will be found fully illustrated in the wherein, p

Figure 1 is a perspective view showing accompanying drawing,

fragments of a screen, the cross-bar attached. to the lower edge thereof and one of the guides in which the ends of the cross-bar travel; Fig. 2 is a horizontal sectional view of what is shown in Fig. 1, taken through the cross-bar and guide; Fig.3 is a horizontal sectional view of an alternative form of the guide; Fig. 4 is a vertical sectional view of the cross-bar; Fig. 5 is a fragmentary view of the screen and a part of the cross-bar attached thereto; Fig. 6 is a plan of the screen; and, Fig. 7 is a fragmentary View of a window, showing my improvement.

The screen a, wound on the roller a journaled in the frame 10, is provided along its side edge with means to thicken-up the same, as tape, braid, cord or the like material b woven into the screen preferably in two spacedparallel rows, the same affording support to the screen against being pulledor working out of its guides, as will appear, and performing certain other functions which are not material in the present lnstance and are fully explained in my aforesaid application.

To the lower edge of the screen is attached the cross-bar c. This includes the sheet metal strip d bent longitudinally to form a hollow cross-sectionally rectangular portion 6; having one edge-portion f standing vertically and the other edge-portion g likewise standing vertically and relatively close to portion f and having its edge 72, bent off at right angles to form the channel 5; said cross-bar also includes the sheet-metal strip y' having each end split for a short distance inwardly and longitudinally and the portions is each side ofthe split rebent one in one and the other in the other direction, so that each portion is grips the side edge of the screen, whose lower edge is folded around the strip 7', as shownin Fig. 5. The strip j, having the screen thus attached thereto, is fitted between the portions f and g of the strip d, whereupon rivets Z are utilized to secure the parts together.

Each guide m for the side edge of the screen and the end of. the cross-bar consists of strips 71. of sheet-metal bent longitudinally to form together a cross-sectionally hollow structure affording a slit 0 for the reception of the marginal edge of the screen and the end of the strip j (which, it will be noted, forms'a projecting fin. on the crossbar)the slit being too narrow to permit the thickened portions 6 of the screen or k of the strip j to pass therethrough-and also to form the longitudinal flange p, which may project at any desired angle according to the disposition of the surface of. the window frame 1) against which the guide is to be secured, see Figs. 2 and 3, for instance. In the present instance, this flange is formed by folding the edge of one of the strips forming the guide around the edge of the other. I do not wish to be limited to forming the guide of two pieces of metal or otherwise to the precise construction thereof described. Theguide is secured in place by screws or the like passed through its flange into the woodwork of the window frame.

For securing the screen at definite eleva tions, a spring-pressed latch in the form of a lever 2, pivoted on a vertical axis in the cross-bar andhoused in its channel 2', may

be provided, the outer end thereof project are pressed upon at their inner ends until their outer ends clear the stops 2'.

' My construction of the cross-bar and guides involves not only simplicity and durability, Without undue cost attending the manufacture and installation of the.

parts, but it imparts when in place a finish to the window opening and insures facility in the operation of the screen; the cross bar runs true in the guides m not only because its hollow'portion e, which afiords a convenient grip to the operators hand, ob-

tains an adequate bearing surface against each guide, but because the ends'of the strips 7 are'confined in the slits 0 formed in said guides, because of the rebent portions 70, which are somewhat thicker than the slits are wide.

It will be observed that the edge It, as well as the hollow portion e of the crossbar, affords a fingerhold for operating the cross-bar. At the back of the ledge formed by'the edge It the strip f upstands somewhat, affording a guard for the screen which protects the latter from vbeing bulged outwardly when the cross-bar is raised or lowered. I 7

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

1. In combination, the structure having a rectangular opening to be screened and elongated guides at opposite sides thereof, a

roller journaled at the third side of said Opening, a screen wound on the roller,,and an elongated sheet metal part having a hollow longitudinal portion and longitudinal edge-portions arranged in parallel planes and gripping between them the freeend edge of the screen, said part being engaged at its end portions in the guides.

2. In combination, the structure having a rectangular opening to be screened and elongated guides at opposite sides thereof, a roller ournaled at the third side of said. opening, a screen wound on the roller, and an elongated sheet metal part haying a hollow longitudinal portion and longltudmal edge- 'the screen, said part being engaged at its; end portions in the guides and its hollow portion having its ends adapted to abut said opposite sides of said structure.

3. In combination, the structure having a rectangular opening to be screened and elongated guides at opposite sides thereof, a roller journaled at the third side of said opening, a screen wound on the roller, and an elongated sheet metal part including an elongated sheet metal member and a sheet metal strip having its ends engaged in the guides, the free-end edge of the screen bein attached to said strip and the first-name member having longitudinal edge-portions arranged in parallel planes and gripping between them the free-end edge of the screen and said strip.

4. In combination, the structure having a rectangular opening. to be screened and elongated guides 'at opposite sides thereof,

a roller journaled at the third side of said opening, a screen wound on the roller, and

an elongated sheet metal part including an a roller journaled at the third side of said i opening, a screen wound'on. the roller, and an elongated sheet metal part-having a longitudinal groove in the relatively inner side thereof, a latch pivoted in the groove, and stops on said structure adapted to be engaged by the latch. V

6. In combination, a screen and a sheet metal strip having one edge of the screen extended around the same, and the end por-' tion of the strip being rebent upon the screen and holding the same fastened around the strip. v

I. In combination, the structure having "'a rectangular opening'to be, screened and elongated hollow guides at opposite sides thereof having longitudinal slits therein, a roller journaled at the third side of said opening, a screen wound on the roller, and a sheet metal strip having the free-end edge of the screen attached thereto, the ends of the strip projecting into said slits of the guides and having rebent portions thicker than said slits are wide.

a rectangular opening to be screened and elongated guides at opposite sides thereof, a roller journaled at the third side of said opening, a screen Wound on the roller, and a cross-bar having its ends engaged in said guides and being attached to the free-end edge of the screen, said cross-bar having a longitudinal finger ledge on the inner side thereof and a screen-guard upstanding from the back of the ledge.

In testimony whereof I affix my signature in presence of tWo Witnesses.
