CURTAIN ROD Filed July 5, 1924 Patented July 19, 1932 PATENT OFFICE ALEX ZIELINSKI, OF MILWAUKEE, WISCONSIN CURTAIN ROD Application filed July 5,

This invention relates to a curtain rod.

The curtain rod to which the invention applies in particular is adjustable to window frames of diflerent widths and is frictionally held in adjusted positions without the aid of screws or other fasteners.

An object of the invention is to provide a holder of this character which is freely extensible but firmly held against collapsing and which may be easily and readily applied to window frames of widely varying widths.

Another object of the invention is to provide a curtainrod which may be economically manufactured.

The invention is illustrated in the accompanying drawing in which the views are as follows:

Fig. 1 is a view of a curtain rod embodying the invention.

Fig. 2 is a view of one of the inner rods.

Fig. 3 is a detail view showing a catch for holding the rod of Fig. 1 extended.

The invention comprises, in general, three telescoping members 1,2 and 3.

The central telescoping member 2 comprises a tube or casing having a longitudinal slot 4 formed near one end thereof.

A series of holes 5 are formed in the tube in line with the above mentioned slot, but spaced longitudinally therefrom. These holes 5 are equi-distantly spaced to permit of varied adjustment.

An annular depression is made in the tube between the slot 4 and the holes 5 to provide a shoulder 6 upon the inside thereof.

The member 1 has a headed pin 7 mounted near the end thereof which is in telescopic engagement with the member 2. This pin 7 projects through the slot 4 and is adapted to travel therein. The relative movement of menbers 1 and 2 is limited by the slot 4 and Within the tube 2 a spring 8 is mounted between the end of the rod 1 and the shoulder 6. This spring serves to hold the rod 1 in extended position with respect to the tube 2, the outward movement of the rod 1 being limited by the pin 7 in slot 4.

This arrangement permits of a slight alteration in the longitudinallength of the rod,

which is necessary in applying the same to a frame.

The rod 3 is in telescopic engagement with ths1 tlube 2 at the other end thereof from the re On the inner end of the rod 3 a groove 9 is located. A hole 10 extending transversely of the rod 3 connects with said groove 9. A catch 11 is adapted to be placed in this groove 9 and an offset end 12 of the said catch extends downwardly into the hole 10.

The other end of the catch 11 is formed with an upwardly projecting turned end 13.

The head 13 of the catch 11 is adapted to engage in and project through the various holes 5 in the tube 2.

Rubber or other suitable holding tabs 14 are mounted on the ends of rods 1 and 3.

In mounting the form just described. the rod 3 is pulled outwardly with respect to the tube 2 so as to disengage the head 13 of the catch from the hole 5.

This disengagement is possible because the upwardly inclined portion of the head 13 acts as a cam to depress the catch 11.

When the head 13 is thus disengaged. the rod 3 is rotated with respect to the tube 2 until the catch 11 is out of alinement with the series of holes 5.

When in this position. the rod 3 may be either extended or pushed in with respect to the tube 2. When the desired position has been obtained. the rod 3 is again rotated in a counter-direction until the head 13 of the catch 11 snaps into the desired hole 5. The rod is then ready to be placed in the window frame.

A slight amount of adjustment is obtained by the sliding movement of the rod 1 within the tube 2 against the force of the spring 8.

This movement permits of the necessary change in length of the curtain rod for placing the same in the window frame.

In practice, it has been found convenient to place the cap member 14 on the rod 1 against the frame of the door or window in the position desired, press inwardly on the tube 2. thus compressing the spring'8, move the entire rod In the appended claims the terms casin and rod are to be used interchangeab y wherever applicable. The invention is. susceptible of various modifications and forms within the spirit of the invention and the scope of the appended claims.

What I claim is: l. Anadjustahle curtain rod comprising a tubular casing' having therein a longitudinal slot and a series of ape'rtures, a rod arranged 11110116 end of saidcasing, a spring arranged in sald casing and tending to force said rod outwardly, azpinlfixed in'said rod and extending through said slot tolimit the outward moveinentof said rod, a second rod arranged in the otherend of'said oasing'and' havmga-longitudmal groove and a trans- V verse bore, a catch arranged in said'groove and said bore and having a cam faced head to engage any one of said apertures and hold said rod against movement inwardly of said casing but permittingsaid rod to be drawn outwardly of said casing, and an abutment arranged upon the outer end of each rod.
