CURTAIN ROD THREADING ATTACHMENT Filed July 9, 193B @Em/(fm Patented Nov. 7, 1939 UNI-TED STATES PATENT orf-'lcs 1 Claim.

My present invention relates to curtain rods, and is directed to provide a quickly attachable and detachable device to the end of a curtain rod which will aid in threading the rod thru the curtain, and will also protect the curtain from damage or injury during the operation of applying the rod therethru.

My present invention is designed to provide a non-metallic curtain rod attachment and curtain protecting member which will t automatically a large range of sizes of curtain rods, and which will still further be suitable for attachment to curtain rods whether round, tubular, square, open channel, or any other of which I am aware.

In carrying out my invention, I provide a nonmetallic device, preferably of plastic material, such as Bakelite, Celluloid, or equivalent, having inherent resiliency, and form the head or threading and protecting portion of suitably rounded or pointed contour to thread the rod to which the device is attached thru the curtain, protecting the curtain as well and eliminating all dangers of sharp points, ridges, or the like which are so objectionable in metallic devices.

I then form, preferably integrally with the head, two or more projecting prongs having inherent resiliency of the plastic material itself and which are capable of and suitable for being threaded on to the open end of enclosed or channel curtain rods. By providing a plurality of such resilient prongs, I can quickly attach and detach my device to any style curtain rod, whether enclosing the central prong, two prongs, or all three, as will be more fully explained.

The plastic material being Vsmooth and rounded cannot damage any article with which it comes in contact, and may be so quickly attached and detached as to be used over and over again in- 0 definitely and should last for years. I can also make the same in any attractive color or finish, which is readily obtained by the modern plastic material.

Referring to the drawing illustrating a pre- 4 ferred embodiment,

Fig. 1 is a perspective View of a typical device Fig. 4 is a cross-sectional view on the line 4--4A of Fig. 3; f

Fig. 5 illustrates the device attached to a rod of narrow diameter;

(Cl. 22S- 7105) Fig. 6 being a cross-sectional view on the line 6-6 of Fig. 5;

Fig. 'l is a further View illustrating the attach, ment to an intermediate size rod;

Fig. 8 being a cross-sectional view on the line 8 8 of Fig. 7, and

Fig. 9 is a view illustrating the attachment of the device to a differing diameter rod wherein a notch in the prongs themselves constitutes the stop and end thrust portion against which the l0 rod bears.

As shown in the drawing, my device, preferably of plastic material as above explained, comprises a suitable head I preferably formed with an oval or conical portion which will thread thru the cur- 15 tain readily. This head is of suiiicient size to be of greater diameter and, therefore, to protect and conceal any normal size curtain rod with which it is intended to Ibe used. The rear face of the head is formed substantially in a single plane, 20 as shown at 2, from which the prongs of the same material project. These are preferably three in number, and, as herein shown, cc nsist of the middle or intermediate prong 5l and side prongs 6 and l. 'Ihese have rounded exteriors and may 25 be flat on the inner faces, as clearly indicated in Fig. 1, and are of substantial length and resiliency to afford the attaching means and spring grip on the curtain rod with which they are to be fitted. Preferably, also, I form these prongs, 30 particularly the outer ones 6 and I, with a slightly tapering shank from adjacent the portion 2 of the head to a shoulder 8.

'Ihis enables a sliding fit to be secured and facilitates the binding action between the device and the curtain rod where a large diameter such as I8, Fig. 3, is employed. The shouldered portion 8 may be utilized to constitute the stop or end thrust of a curtain rod of the size, for example, as shown in Fig. 9 where the rod I2 will abut 40 against the shoulders 8 on each of the prongs as illustrated in Fig. 9.

Referring to the form shown in Figs. 5 and 6, the small curtain rod I5 is engaged yieldingly by the central prong 5 and the exterior end 45 prongs 6 and I simply extend smoothly down the outside of the rod I5 and permits this curtain rod of relatively small diameter to be yieldingly attached thereto.

Referring to the forms shown in Figs. 7 and 50 8, the curtain rod or channel I6 is yieldingly secured by the tting in of thevmiddle prong 5 and one side prong 1, as clearly illustrated.

I prefer to taper the end portion of each prong as shown fat 20 to facilitate the attachment of 55 thesametotherodwhichwillinitially compress' the prongs to secure the spring attachment between the prongs and the rod.

- Thus, it will be appreciated that I have dethe device to be attached to curtain rods of varying diameters or sizes, whether tubular or channel formation, and all in a preferably non-metal- `lic member oi' resilient plastic material.

I claim:

curtain-rod threading device of `the'kind described, comprising plastic material formed with a conical head anda plurality of projecting prongs integral with said head extending therefrom, each prong having a shoulder intermediate. its end and a reduced portion in each prong` beyond said shoulder tapering to a rounded point, saidprongs being resilient widthwise and adapted to yieldingly engage curtain rods of tubular or channel construction and of varying 10 WILLIAM MGGURK.
