CURTAIN-no1).

Specification of Letters Patent.

Patented Jan. 11, 1921.

Application filed January 7, 1920. Serial No. 349,854.

To all whom t may concern.' s

Be it known that I, JAMES H. Bove, a citizen of the United States, residing at Chicago, in the county of Cook and rtate of Illinois, have invented certain new and useful Improvements in Curtain-Rods, of which the following is a specification.

This invention relates to curtain rods of the so-called iiat rod type at present eXtensively used, and has reference more particularly to eXtensible telescoping rods of this type. The leading objects of the invention are, to provide a rod possessing a high degree of strength and rigidity against bending strains in both vertical and horizontal planes, to provide a rod the sections of which will slide easily upon each other even though the rod sections may be slightly bent or bowed in a front and rear direction, to provide a rod that shall be free from any downward bending or sagging tendency under the weight of the curtain, and, generally, to provide an improved curtain rod of the type specified characterized by simplicity and economy of structure and ease of manipulation in mounting and adjusting the same.

In order that the invention may be clearly understood I have illustrated a preferred embodiment thereof in the accompanying drawing, in which- Figure 1 is a front elevation of the upper portion of a window casing, showing my improved curtain rod mounted thereon.

Fig. 2 is an enlarged fragmentary rear elevation of the intermediate telescoping portions of the two rod sections; and

Fig. 3 is a further enlarged cross-section on the line 3--3 of Fig. 2.

Referring to the drawing, 5 indicates the top and 6 the side members of an ordinary window frame or casing, on which latter are mounted brackets 7 Supported by and between the brackets 7 is my improvel cur-v tain rod comprising the telescoping rod sections designated generally by 8 and 9. The larger rod section 8 comprises the flat front wall 10, rounded upper and lower edge walls 11, and flat rear wall sections 12 having the inwardly turned oblique free margins 13; all of said parts being folded and bent to the shape shown from a single sheet metal blank. The inturned margins 13 do not touch each other, but form between them a central narrow longitudinal slot 14; in the rear wall of the rod.

The smaller rod section 9 has substantially the same shape as the larger section 8, but is sufliciently smaller in transverse dimensions to telescope within the latter. It is also folded and bent to form from a single sheet metal blank, and comprises the flat front wall 15, rounded upper and lower edge walls 16, and flat rear wall sections 17 having the inwardly turned oblique free margins 18; the free edges of the latter being spaced apart slightly wider than the free edges of the margins 13. It will be observed by reference to Fig. 3 that the portion of the inner rod section that lies within the outer rod section is not in surface contact with the latter throughout its entire eX- tent, but bears thereon only at its frontV wall .15 and at the edges of its inwardly turned marginal portions or flanges 18 which engage with the edges of the inwardly turned marginal portions or iianges 13 of the outer rod section, the transversely acting elasticity of the two rod sections maintaining the front walls 10 and 15 in contact and likewise the edges of the

iianges

13 and 18 in contact.

This affords sufficient friction between the two rod sections to prevent them from sliding apart by gravity when mounting the curtain on the rod or mounting the latter on, or dismounting it from, its supporting brackets '7 and at the same time it renders the rod adjustable to the required length under a light pull or push. The described construction also prevents sagging, since the elastic pressure contact of the edges oi the

flanges

13 and 18 is continuous throughout the telescoped portions of said rod sections and one component of this pressure acts in a vertical direction to oppose relative movement or yield of the rod sections in such vertical direction. Furthermore, the two sections will readily telescope, even though either or both of them be slightly bent or bowed in a front and rear direction, owing to the elasticity of the

rear wall sections

12 and 17 which are free to yield outwardly under pressure ot the flanges 18 of the inner rod section on the flanges 13 of the outer rod section. Again, the inturned margins or

fianges

13 and 18 directions of both its vertical and horizontal transverse axes, affording an even stronger greatly stiien and strengthen the rod in the f resistance to bending strains than is obtained by extending the rear wall sections toward each other until their free edges meet.

I claim- 1. A hollow flat curtain rod, Comprising telescoping rod sections each having a solid fiat front wall and a longitudinally slotted flat rear wall, the marginal portions of said flat rear wall on either side of the slot of the latter extending inwardly toward the 'front wall continuously throughout the full length of each rod section.

2. A hollow dat curtain rod, Comprising telesooping rod sections each having a solid flat front wall, rounded edge walls, and a longitudinally slotted flat rear wall lying substantially parallel with said front wall, the marginal portions of said flat rear wall on either side of the slot or" the latter extending inwardly toward the front wall continuously throughout the full length of eaeh rod section.

3. A hollow flat curtain rod, comprising telescoping rod sections each having a solid flat front wall, rounded edge walls, and a longitudinally slotted flat rear wall lying substantially parallel with said iront wall, the marginal portions of said fiat rear wall on either side of the slot of the latter extending inwardly toward the front wall; the teleseoping portions of said rod sections lying in Contact with each other substantially only at their front walls and the inwardly extended marginal portions of their rear walls.

4. A hollow flat Curtain rod, comprising telesooping rod sections each having a solid i'lat front wall, rounded edge walls, and a centrally longitudinally slotted flat rear wall lying substantially parallel with said front wall, the marginal portions of said flat rear wall on either side of the slot of the latter extending obliquely inwardly toward the front wall; the telesooping portions of said rod sections hearing upon each other substantially only at their front walls and at the free edges of the inwardly extended marginal portions of their rear walls.
