CU RTAI N- POLE.

SPECIFICATION forming art of Letters Patent No. 702,723, dated June 17,1902.

' Application filed Decem'ber 4, 1901'. Serial No. 84,646. on model.)

be supported without the aid of the ordinary rings and pins.

, Briefly described, the invention comprises a hollow pole preferably constructed of metal and which is made in two sections or members substantially equal in size. One of these sections or members may be termed as a female section, having a'spring-pocket throughout its length which receives and embraces the tongue formed on the other section. Each of the sections have their lower edges turned upwardly at an incline and the upwardly-extending flanges or tongues thus formed are adapted to embrace the curtain between the same and securely hold it'in position, the two sections or members of the pole being locked securely after engagement by means of the sleeves placed on the ends of the pole, all of which construction willbe' hereinafter morefully described, and specifically pointed out invthe claims.

In describing the invention in detail reference is had to the accompanying drawings, forming a part ofthis specification-,and wherein like numerals of reference indicatecorr'e sponding parts throughout the several views,

in which- Figure 1 is a front elevation of a curtainpole constructed in accordance. with my invention, showing a curtain supported therefrom. Fig. 2 is a detail perspective view of a part of the pole, the sections or members being supported so as to clearly illustrate the construction. a Fig. 3 is a like view of a part of the pole with the sections .or members locked together. Fig. 4 is a like View of a modified form of construction.

My improved curtain pole is preferably and more cheaply manufactured from a suitable thickness of sheet metal, and a cheaper manner of manufacturing is the irregular- *sided pole, as shown in Figs. 1, 2, and 3,

though it may be preferable to construct the pole round in cross-section, as shown in Fig. 4:. In either construction, however, the pole consists of a female section 1 and a male section 2. The female section 1 has its upper edge bent'inwardly at an incline to form a wall 3', thenoutwardly to form the wall 4, these two walls forming a substantially V- shaped pocket, the edge of thesection 1 beingthen bent downwardly at an incline, as at 5, with the free edge 6 bent downwardlyin a vertical manner. The section 2 of the pole has its upper edge bent downwardly to form .a shoulder 6'. and then bent at'an incline to form the tongue 7, which is adapted to frictionall'y engage with: the walls 3 4 of the elon 5, carried by the section 1, serves as a guide to insure an easy and ready engagement of the tongue 7 with the pocket of the section 1, this tongue being forced into firm engagement bypressure upon thetwo sections. Each of the'sections has its lower edge turned upwardly at: a slight incline and doubled over upon themselvesjto strengthen the same, this upwardly-extending flange 8 of the section beingadapted to embrace the, curtain 9 therebetween and securely hold the same. The sections 1 and 2 of the pole are secured in a locked position by means of a sleeve 10, which frictionally engages on the ends of the pole and which-are preferably provided with the ornamental knobs 11f0r adding to the appearance of the pole.

In operation the curtain may be placed upon the flange 9 of the section 1, overlapping the "same, and the section 2 is then placed in positionjwith' thejflan ge 8 thereof engaging the curtain and the tongue 7 forced into the pocket formed bythe spring-walls 3 t of the section 1, securely binding the: curtain be:- tween the two flanges at the lower edge of the sections, and the latter arethensecured in a locked position by'means of the sleeves 10 on the ends thereof.

In constructing the pole it will be observed that the same may be made of various formssuch as octagonal, sextagonal, or the like-- and that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A curtain-pole comprising two metal sections one having an elongated spring-pocket and the other having a tongue for engagement in said pocket, flanges formed integral with said sections between which the curtain is held, and means for securing the sections in a locked position, substantially as described.

2. A hollow metallic curtain-pole comprising a male and a female section, the female section having a spring-pocket throughout its length at the upper edge, and the male section having a tongue for engagement in said pocket, and flanges carried by said sections between which the curtain is held, substan- 2o tially as described.

3. A hollow metallic curtain-pole comprising a male and a female section the female section having its upper edge bent upon itself to form a pocket and the male section having an inclined tongue for frictionally engaging with the walls of said pocket, means carried by said sections at their lower edges for securing the curtain, and means engaging the ends of the sections for securing samein a locked position, substantially as described.

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