CURTAIN ROD THREADER Filed Aug. 4, 1952 jfjllll Lawrence F C 1/7/762/71 Patented Oct. 17, 1933 UNITED STATES CURTAIN ROD- THREADEB Lawrence F. Cutlibert, Ogdensburg, N. Y., as-

2 Claims. (Cl. 223-38) The present invention relates to an improved curtain rod threader and method of making the same.

An essential feature of the invention is to I provide a simple, economical and efllcient threader attachment or pilot which may be readily detachably connected to either the large or small end of a sectional channel-shaped curtain rod to guide the curtain rod through the case or loop of the curtain, draperies or the like without danger of tearing or snagging the material.

A further object consists in a new and improved method of forming the threader from a metallic blank and with a minimum number of steps or operations, so that the threaders may be made from stock material in large quantities at a minimum expenditure of time and labor, and at very low cost.

Other objects and advantages of the invention will become apparent from the following description when taken in conjunction with the accompanying claims and drawing.

Referring to the drawing wherein is shown a preferred embodiment of the invention:

Figure 1 is a view of a flat blank having the body, neck and head of the threader stamped thereon.

Figure 2 is a view similar to Figure 1 showing the outer marginal portion of the head bent to form the curved outer end and smooth side walls of the threader.

Figure 3 is a view similar to Figure 2 showing the body having its sides bent inwardly to form the flanges and the threader in its complete or final form.

Figure 4 is a perspective view of a sectional channel-shaped curtain rod with the threader connected to the ends thereof.

Figure 5 is a vertical sectional view of one end of the curtain rod and threader.

Figure 8 is a sectional view taken substantially along the line 6-6 of Figure 5, and

Figure 7 is a sectional view taken substantially along the line 7-7 of Figure 5.

Referring to the drawing in which like numerals indicate like parts in the several views, the sequence of steps employed in forming the threader from a single blank of material is shown in Figures 1, 2 and 3. The metallic blank 10 which may be made of any suitable material, is first stamped to form the body 11, the neck or reduced portion 12 and the head 13 which is preferably of oval shape. The enlarged head 13 is of such a size that when it is subjected to a suitable drawing or dieing operation, it will be formed into the curved or arch-shaped penetrating end 14 (Figure 2) and the side flange 15 which is disposed substantially parallel to the opposed fiat wall 16 of the head. The opposed sides of the body are similarly distorted 00 by a suitable drawing operation to form the spaced flanges 17 so that the threader or pilot in its final shape assumes the form as shown in Figure 3. Obviously, the operation may be reversed and the flanges 17 formed before or simultaneously with the penetrating end 14 and side flanges 15.

In order that the threader may be readily connected to either end of a sectional channelshaped curtainrod such as 18 (Figure 4,) the body 11 is formed in substantially the same shape as the curtain rod, and of such a size that it may conveniently fit or slide within the large end 19 and over the small end 20.

It will be observed that the head 15 is of greater cross sectional dimension than the body 11 when the threader is formed and is provided with shoulders 21 which are spaced by the neck 12 from the adjacent ends of the flanges 17 so as to limit the inward movement of the threader when it is inserted in the curtain rod.

The head 13 in its final form is shaped so that both the penetrating end 14 and the sides 15 and 16 provide smooth exposed surfaces in order that when the threader is inserted within the 86 loop or case in the hem of the curtain, it will spread the folds of the material and permit the curtain rod. to pass freely therethrough without danger of cutting or tearing the material.

As the body 11 of the threader or pilot is ar- 90 ranged to slidably flt either within or encompass the ends of the curtain rod, it will be seen that it may readily be connected to either end of the rod to thread the same through the curtain and be removed therefrom when the parts are properly assembled. In other words, the threader dispenses with the use of two threaders as heretoi'ore necessary for guiding channel-shaped sectional curtain rods through draperies or curtains. Moreover, as the threaders are formed from a single blank of material and with a minimum number of steps or operations, they can be made in large quantities and at very low cost.

It is to be understood that the curtain rod threader and method of making the same are merely illustrative and that such changes may be made without departing from the spirit of the invention as fall within the purview of one skilled in the art and the scope of the appended claims. no

sheet material having an enlarged curved head, the integral sides of said body being bent over to form opposed channel flanges, a reduced'neck connecting the head to the body, said head provided with shoulders adjacent the ends of said flanges, for limiting the inward movement of the threader on the curtain rod, said flanges arranged to slidably flt either end of the curtain rod.
