June 6, 1933. w. s. HAMM CURTATN CONSTRUCTION Filed Aug. 18. 1932 Patented June 6, 1933Y UNITED STATE-s PATENT OFFICE WILLIAM` S. HAMM, OF ELKHART, INDIANA., .ASSIGNOR T THE ADLAKE COMPANY, OF

` A CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS` CURTAIN CONSTRUCTION Application filed August 18, 1932. Serial No. 629,257.`

This invention has to do with window curtains of the type used in automobiles, and is particularly concerned with the construction of the hatten in the hem at the lower edge of the curtain and the way in which the pull cord for the curtain is secured to the hatten.

The purpose of the invention is to provide an improved batten of inexpensive construction which is so shaped at the location of the pull cord as to` facilitate attachment of the latter, produce a connection of neat and pleas ing appearance, prevent the hatten from turn ing in the hem, and maintain the batten centei-ed with respect to the ends of the hem.

Other more specific objects and advantages will be apparent to those skilled in the art upon a. full understanding of the special shaping and purpose of the cord-supporting portion of the batten.

In order that the invention may be readily understood, two slightly different structural forms of the same are presented herein, but it will of course be appreciated that such forms are intended primarily for the purpose of exemplitication and that* the invention is susceptible of embodiment in other structurally modified forms coming equally within the scope of the appended claims.

In the accompanying drawing:

Fig. 1 is an insideV face view of an automobile window curtain equipped with the improved batteri;

Fig. 2 is a fragmentary view correspond- Jing to the central portion of Fig. 1, showing in more detail the special shaping of the bat- 1 ten at the location of the pull cord;

Fig. 3 is a vertical transverse section through the assembly, taken on line 3 3 of Fig. 2; and

Figs. 4 and 5 are views, corresponding to Figs 2 and 3, respectively, of a modified form of the invention.

The form of the invention shown in Figs. 1, 2 and 3 will first be described. In those views a soft fabric curtain 10 is shown mounted on a spring-wound roller 11 and poi sitioned at the inside of a window 12. The

curtain has a hem 13 at its lower edge in is preferably a straight metal rod of circular cross section, and the ends of the same, which project equal distances beyond the ends of the hem, are preferably flattened out in a horizontal plane and' apertured to provide small eyelets 15, similar to those shown in Hamm Patent No. 1,841,730 of Jan. 19, 1932, for the reception of vertically extending guide cords 16.

At the center of the hatten 14 the latter is tiattened out and apertured, in a vertical plane ati right angles to the plane of the eyelets 15, whereby to provide a recess or seat 17 for the reception of a pull cord 18. The side walls of the hem 13 are provided, at points opposite the seat 17, with holes 19 which permit passage of the cord 18 through the hem into engagement with the seat. Y

The cord 18, which is usually in the form of a loop.` with a tassel 20 attached to the same, is threaded through the holes 19 across the seat 17 and then looped back about itself beneath the hem is a tight-ly drawn slip knot.

The cord- 18 thus pulls directly against the` seat portion 17 of the rod, in a small tie formation which is disposed entirely beneath the upper edge of the hem, and the cord portion which pass through the holes 19 across the seat 17 engage with the sides 21 of the seat upon any tendency of the rod to shift endwise in the hem, thereby maintaining the guide cordeyelets 15 evenly spaced from the ends of the-hem and in horizontal positions at all times, the underslung disposition of the seat 17 with respect to the top of the rod Serving to leep the rod from turning out of its proper position. i

In the modification shown in Figs. 4 and 5, the seat 22 on the hatten 23 for the reception of the pull cord 24 is produced by downwardly offsetting the rod at the location of the cord. By constructing the seat in this way, the latter is broughtbelow the top surface of the rod proper and the converging sides 25 of the seat bind with the cord upon any tendency of the rod to move endwise.` In this embodiment of the invention, as well asl in the first described form, the formation of the seat produces a slight downward bulge in the roddirectly beneath the seat, which yso bulge may cause the rod to fit the hem quite snugly at that point and thereby further assist in prevent-ing any movement of the rod in the hem.

The improved batten and pull cord assembly which forms the subject matter of this invention provides a very neat and secure connection between the parts, while at the same time permitting of easy insertion or removal of the rod, it being merely necessary to unloop the cord 18 to free the rod.

I claim:

l. In a window curtain assembly of the type described, a curtain provided with a hem at its lower edge, a batten positioned in the hem and provided at its center with a seat below the level of the top of the hatten, and a pull cord passing through openings in the side walls of the hem opposite the seat into engagement with the latter.

2. In a window curtain assembly of the type described, a soft fabric curtain provided with a hem at its lower edge, a substantially straight round wire bat-ten positioned in the hem and provided at its center with a curved seat below the level of the top of the hatten, and a pull cord passing through openings in the side walls of the hem opposite the seat into engagement with the bottom of' the latter.

3. In a window curtain assembly of the type described, a soft fabric curtain provided with a hem at its lower edge, a substantially straight round wire hatten positioned in the hem with its ends projecting therefrom and provided at its ends with horizontally disposed eyelets for sliding engagement with vertical guide cords and at its center with a recess below the level of the top ot the hatten, and a pull cord passing through openings in the side walls of the hein opposite the recess into engagement with the bottom of the latter, said cord being so positioned with respect to the sides of the recess in the hatten as to prevent any appreciable endwise movement of the hatten in the hem.

4. In a window curtain assembly of the type described, a soft fabric curtain provided with a hem at its lower edge, a substantially straight round wire batten positioned in the hem with its ends projecting therefrom, said batten having its projecting ends. flattened out in a horizontal plane and apertured for the reception of guide cords and having its center portion flattened out in a vertical plane and apertured, and a pull cord passing through openings in the side walls of the hem into the aperture in the center portion of the hatten.

5. In a window curtain assembly of the type described, a soft fabric curtain provid` ed with a hem at its lower edge, a substantially straight round wire batten positioned in the hem with its ends projecting therefrom, said batten having its projecting ends {iat- WILLIAM S. HAMM.
