V H. AUSLANDER CURTAIN ROD THREADING DEVICE Filed Feb. 8, 1958 INVENTOR Hnry Ausldlzder BY P 1 1 It) I ATTORN EY Patented Aug. 22, 1939 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to new and useful improvements in a curtain rod threading device.

More specifically, the invention proposes the construction of a one piece sheet metal thread- 1 ing device which may be attached to the end of a.

fiat C-shaped rod for facilitating the passage of the rod through the tubular edge formed on the top of a curtain.

Still further the curtain rod threading device, according to this invention comprises a bottom wall having a pointed front end and flanges continuing from the sides of the bottom wall and which are adapted to engage around the edge portions of an open C-shaped rod for holding the threading device in position thereon.

Still further it is proposed to bend portions of the flanges downward towards said bottom wall to prevent these edges from catching upon the sides of the tubular edge on the top of the curtain to prevent the same from being torn.

Another object of this invention is to provide openings in said flanges and to bend the ends of the fiat C-shaped rod up slightly so as to engage these openings to assist in holding the threading device in position thereon.

Another object of the invention is to bend inwards an area at the rear of the flanges upon themselves formingresilient portions for engaging the edges of the curtain rod for assisting in holding the threading device in position thereon.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure Fig. 1 is a bottom elevational view of a curtain rod having a threading device according to this invention.

Fig. 2 is a top elevational view of Fig. 1.

Fig. 3 is a sectional view on the line 33 of Fig. 2.

Fig. 4 is a sectional view on the line 4-4 of Fig. 2. I

Fig. 5 is a sectional perspective view illustrating a modification of the invention.

Fig. 6 is a sectional view on the line 66 of Fig. 5.

Fig. 7 is a view similar to Fig. 2 but illustrating a still further modification of the invention.

Fig. 8 is a perspective view of Fig. 7 having portions thereof broken away to reveal interior construction.

The curtain rod threading device, accordingto this invention; comprises'a one piece sheet metal device having a bottom wall I 0 formed with a pointed front end ll] and parallel sides lob at its rear end. Flanges ll continue from the sides of the bottom wall and have portions ll extending over the edge portions. of the bottom wall I0 forming an open flat C-shape at the rear end of the device into which the end of a flat C-shaped curtain rod I2 may engage. The front ends N of the flanges l l terminate in a point at the pointed front end Ill of the bottom wall H]. Each of the flanges II has a cutout portion l3 at its center and the edge portions of the material to the front of the cutouts are bent slightly downwards, and the edge portions to the rear of the cutouts bent inwards to engage the free edge of the curtain rod [2 to frictionally hold the threading device in position upon the end of the rod. I

The material to the front of the cutout I3 is bent downwards to prevent these edges from catching on the material forming the tubular edge M on the top of the curtain l5. The material at the rear of the cutout portions I3 is bent slightly downwards and arranged upon an angle with relation to the parallel side portions of the bottom wall H! for engaging the free edges I2 of the C-shaped curtain rod I2 for holding the threading device in position thereon.

The operation of this form of the invention is as follows:

When it is desired to pass a flat c-shaped curtain rod through the tubular edge formed on the top of the curtain IS the threading device is slipped on the end of the C-shaped curtain rod l2 until the material to the rear of the cutouts l3 tightly engages the free edges l2 of the curtain rod 2 to fixedly hold the threading device in position thereon. Then the curtain rod I2 is passed through the tubular edge I 4 by first engaging the pointed end Ill therein and then pushing the threading device through the tubular edge It in front of the rod. l2 to space the walls forming the tubular edge l4 so that the rod will easily pass therethrou-gh. After the rod I2 is completely passed through the tubular edge M the threading device is removed from the end of the rod and the curtain is hung on the window frame.

According to the modification shown in Figs. 5 and 6 the material of the threading device to the rear of the cutout portion I3 is provided with openings l6 and the corners l2 of the free edges l2 of the curtain rod I2 are bent slightly upwards so as to engage into the openings IE to assist the material of the device to the rear of the cutout H3 in holding the threading device in position upon the end of the rod l2.

The operation of this form of the device is as follows:

Ihe threading device is slipped upon the end of the curtain rod l2 and when the rod reaches a position in which the bent up corners l2 will be aligned with the openings I6 they will snap into the openings and assist the material of the device to the rear of the cutout i3 in holding the threading device in position thereon. In other respects this form of the invention is similar to the previous form.

According to the modification shown in Figs, 7 and 8 the end portions of the bent-down areas to the rear of the cutouts 13 are formed with an inwardly extending slit l1 and the portions l 8 divided by this slit I! are bent upon themselves forming resilient portions for engaging the edges I2 of the curtain rod I2. These bent portions l8 are adapted to abut against the free edges of the curtain rod 52 when the rod is passed into the rear end of the threading device to frictionally engage there-against and assist the material of the device to the rear of the cutout l3 in holding the threading device upon the end of the rod l2. In other respects this form of the invention is identical to the previous forms.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself tothe precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is- 1. A device of the class described, comprising a curtain rod of the flat C-shape type, a onepiece threading device for engagement on the end of said curtain rod, comprising a bottom wall having a pointed front end and a rear end having parallel side edges, side walls continuing from the front and rear side edges of said bottom wall and extending at right angles to said bottom Wall, and flanges continuing from the edges of said side walls and being directed towards each other forming a device having an open rear end into which the end of said curtain rod may engage, said flanges being formed withopenings, said curtain rod having the corners of its free edges bent outwards and engageable into said openings in said flanges for holding said threading device in a fixed position upon said rod.

2. In combination with a curtain rod of the flat C-shape type, a one piece sheet metal threading device, comprising a bottom wall having a pointed front portion and a rear portion having parallel side edges, side walls extending at right angles to said bottom wall and continuing from the side edges of the front and rear portions of said bottom wall, and flanges continuing from the edges of said side Walls and being directed towards each other and parallel to 'said bottom wall forming a device having an open rear end into which the end of said curtain rod may engage, said flanges having their front ends terminating at a point superimposed above the point of the front portion of said bottom wall, each of said flanges having a cutout portion at its center, the edge portion of said flange to the front of said cutout being bent slightly downwards, and the edge portion of said flange to the rear of said out out being bent inwards to engage the free edges of the curtain rod, the rear portions of said flanges being formed with apertures, and the corners of the edges of said ourtain rod being bent outwards and being engageable into said apertures for holding the device on said rod.
