Description

June 21, 1938. P. PETRI SPRING cunmm THREADER Filed Dec. 22, 1936 Pezer Fez/ 1' ATTORN EYS Patented June 21, 1938 UNITED. STATES.

PATENT OFFICE 3 Claims.

This invention relates to spring curtain threaders and has for an object to provide a device for facilitating the spreading of the hem of a curtain to promote ease of threading the curtain rod through the hem, the device having spring legs which are adapted to enter between the flanges of all sizes of curtain rods 'so that a single device of this character may be used to thread curtain rods of various sizes throughout a dwelling, through the hems of curtains.

A further object is to provide a device of this character which will be formed of a single length of spring wire, which will be inexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without' departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure 1 is a front elevation of a curtain rod equipped with a threader constructed in accordance with the invention and showing the application of the same to the initial end of a hem of a curtain.

- Figure 2 is a plan view of the parts shown in Figure 1.

Figure 3 is a perspective view of the threader.

Figure 4 is a front elevation of the threader.

Figure 5 is an edge elevation of the threader.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, I0 designates a metallic curtain rod of the' type having longitudinal flanges. As is well known metallic curtain rods of this type are manufactured in a large number of difierent widths.

The curtain hem threader ll comprising the subject matter of this invention, is formed from a single length of wire bent centrally upon itself to form two convolutions l2 and I3 of a spiral, the ends of the wire then being bent to lie against the sides of the spiral so that the convolutions diverge from each other, as best shown in Figure 5. The ends of the wire 14 are then directed substantially paralel to each. other and in the same plane and are provided near their extremities with oiisets or substantially V-shaped bends IS the apexes of which are turned oppositely to each other, as shown in Figure 3, so that the extremities will converge toward each other and thus be easily insertable in a curtain rod of any width.

The threader is applied to the curtain rod by thrusting the extremities of the ends l4 inside of the longitudinal flanges of the curtain rod and 5 then forcing the same longitudinally of the curtain rod by pressure upon the convolutions I2 and i3. The spring ends l4 tend to hold the V-shaped bends I5 in tight frictional engage ment with the inner surfaces of the curtain rod 10 flanges so that the convolutions l2 and I3 may be inserted in the hem 16 of a curtain H whereupon the convolutions will spread the hem laterally as the threader is moved through the hem by pressure upon the curtain rod so that the curtain 15 rod will be easily and quickly threaded into the hem.

From the above description it is thought that the construction and operation of the invention will be fully understood without further explana- 20 tionl What is claimed is:

1. A curtain rod threader comprising a spring wire deformed to provide diverging convolutions of a spiral adapted to enter and spread laterally the hem of the curtain, the ends of the wire being directed from the spiral to lie in the same plane and being provided near the extremities with bends forming jaws adapted to frictionally engage the flanges of a metal curtain rod and 30 anchor the threader to the rod.

. Ward each other.

3. The combination with a metal curtain rod having longitudinal side. flanges, of a curtain hem threader comprising a single length of spring wire bent centrally upon itself to form two diverging convolutions of a spiral adapted to spread laterally the hem of a curtain, the ends of the wire being bent to lie in the same plane and being provided with substantially V-shaped bends the apices of Which are turned outwardly so that the ends of the wire converge toward each other, said extreme ends being adapted to guide the threader beneath the flanges of the curtain rod', said V-shaped bends frictionally engaging the inner surfaces of the flanges and yieldably attaching the threader to the curtain rod.
