CURTAIN POLE 0R ROD.

Application mea August a1, 1915. serial No. 48,252.

To all Awhom t may concern:

. Beit known that I, JOHN A. CRUMP, a citizen of the United States, residing at 322 East Thompson street, Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new. anduseful `Improvements in Curtain Poles or Rods, of

-which the following is a specification.

The invention relates to supports for curtainsjand has for an object the provision of a curtain rodyorpole which willeffectively 1 support-.the curtain or portire in a window a or doorway without necessitating the mar;

ring or injuring of the casing thereof. Amdng other features the invention conytemplates a rod or poleA which is adjustable use isv made of theaccompanying drawings, i

in length to accommodate itself to sashes or doorways of different widths and which can be quickly applied and does not requlre the usual sockets or other means screwed or otherwise secured'in lthe sash or casing for the'purpose of holding the rod or pole in position.r

Still furtherzembodiments ofthe invention reside in a p'ole or-rodfthat is preferably made in sections, one fitting into the other, so that the length of the pole or rod can be easily varied as desired, with suitable -means arranged to prevent accidental disengagement of the sections..

In .the further disclosure of the inventlon forming' a part of this specication, in which similar characters of reference denote corresponding parts in all vthe views, and in which:

' Figure 1 is a sidey elevation of the curtain rod, showing the manner of mounting the same, parts :being broken away to disclose the underlying structure; Fig. 2 is an enlarged fragmentary vertical section taken through the rod at the point of engagement of the sections; Fig. 3 is a' vertical section taken on the `line 3-3 in Fig. 2, and Fig. 4 isa perspective view ofthe element serving to prevent disengagementy of the sections.

Referring to the views, the rod in its entirety is indicated by the numeral 5 and comprises telescoping tubular sections 6, 7, each having a transverse pin 8 passing throughv its inner end as shown, with an elongated loop-like element r9 arranged within the sections and passing around the pins 8,. said pins passing loosely through thespace 10k of the element. ,A y 1 a vAn expansible helical spring 11. ,encircles the element 9 and is also arranged Within the sectionsfwith the ends of the spring abutting against the pins 8,@the ,said spring thereby tending to move lthe sectionsrelatively outward orapart` while .the element 9.prevents relativev `disengagement'. of ,the sections` as mentioned heretofore.

The numeral 12 indicatesthe usual window casing or sides of a doorwayand arranged in the ends of the sectionsto abut against the casing are frictioncushions or holders 13, each providing a rubber orothen frictionhead 15 .having a curved face 16 and held on theL sectionu by .a shank 17 threaded into the-internallyy threadedends 18 of thetubular sections andv'?.

It will now be seen that'whenthe rod in its entirety is` arranged between the sides of the casing as shown in Fig.1, the spring 11 bearing lagainst the pins 8, 4will tend `to move the Sections apart thus causing the heads`15 to bear against` the sides ofthe casing 12. By providing the, curved lfaces 16,;the heads, when compressed by they `action of the spring, will cause the curved facesto almost flatten out and thus `a suction will bejproduced greatly facilitating the holding or supporting power ofthe. heads. The element 9, operating against the. action of the spring, will prevent the sections fromk becoming relatively separated and thus limits their relative outward movement induced by i ing relatively movable Sections, a pin passing through each section adjacent the mner ond thereof, an elongated element engaging with the pins of each section for holding the same together', a spring embracing the elon gated element and abutting at its opposite terminals with the opposed surfaces of each mimosa JOHN A. CRUMP.
