CURTAIN-POLE.

Specication of Letters '.E'atent. Patented Sept. 10, 1912, Application filed August 25, 1911. Serial No. 646,03.

To all whom it may concern:

Be it known that LQHENRY A. ANDERSON, a citizen of the United States, residing at Missoula, county of Missoula, and State of| Montana, have invented certain new and useful Improvements in Curtain-Poles, of which the following isa specification.

, My invention relates to curtain .poles and particularly to poles for curtains and portires 4'which may be adjusted in length-tol suit the width of the Window or door where .they are -to be used.

The object of my invention is to provide a pole of the class mentioned. which may be readily adjusted in length and which, when adjusted, will hold the brackets or support in position' on the lwindow or door frame.

A further object of my invention is to provide an adjustable pole of the class under consideration equipped with means whereby it may be adapted for use lwith `consists 'generally in a curtain pole com prismg a central tubular portion, a pa1r of'end portions telescoping thereiuto, means for locking said portions against relative movement and means threaded Kupon Athe outer ends of the last said portions for engaging the supports and clamping the same against the window or door frames.

My inventionl further consistsin various.,

details of construction and arrangements of ,parts all as will be fully described hereinafter and particularlypointed out in the claims.

My invention will bey more readily understood byreference to the accompanying drawings forming a part of this specication and lin Which- Figure 1 is a plan view,"partially in section, of a curtain pole embodying my invention, and illustrating the same in conjunction with a bracket such as is used for supporting the pole upon a window frame. Fig. 2 is a similar view 'illustrating the pole in `conjunction with socket supports, and "I equipped with means for engaging 'the sockets, Fig. 3 is a detail sectional View illustrating the locking means, Fig. 4 is a section on the line -m of Fig. 3, and F ig.` 5 is a perspective view of one ofthev brackets.

Referring now tothe drawings 1 indi- I cates the central portion of the pole and 2 indicates the end portions. rlhe portions 1 and 2 are tubular and the latter telescope within the former `by which construction the length of the pole may be adjusted. The outer ends of the portions 2lare closed by means of caps 3. The inner end of each of the portions 2 is split, asindicated at 4,

and arranged within each of the split ends `1s a frusto-conleal member 5, the larger end ofewhlch 1s of greater dlameter than` the yinternal diameter of thetubular por@ tion 2.. `It is obvious that by drawing the member 5`within the split endof the member 2, said end will be expanded and bind .tightly within the member 1, thereby lock- -mg the members 1 and 2 against relative The'member 5 1sy longitudinal movement. secured to the end of arod Gwhich extends through the respective member 2 and projects beyond the end thereof, the proj ectingend being threaded as indicated at 7.

When the device is used with a bracket the end-7 is projected through an aperture in the arm of the bracket and a ball end 8 is threaded thereon. The poleis adjusted in leugthto fit between the arms of the brackets, as shown in Fig. 1, and as'the balls are screwed upon ,the ends of the rods f G they will engage the outer .facesof the bracket arms and draw the rod forcing the member 5 within the' split end' of the mein-Y ber 2.

. The bracket which is preferably used with' the pole comprises a plate -9 adapted to rest against the outer fece of a window casing A, a tongue extending outwardly at right angles to the plate 9 and bent back upon itself forming parallel portions 10 and 11 constituting the arm of the bracket, and ears 12 extehding in the opposite Adirection from the arm and provided with prongs 13 which engage into the edges of the window easing The portions 1 0 and 1l are provided `witli perforations 14 to rece1ve the end of the rod 6. When the halls 8 are threaded upon the rods they will engage theouter portion 10 of the bracket arms and clamp the brackets securely upon the Window casing.

In F ig. 2 I have illustrated the device as used in conjunction with sockets -,upon the inner faces of door jambs B. When used in this manner the pole is equipped 'with a sleeve 16 threaded upon the end of the rod 6 and bearing against the cap 3, by

means of which the member 5 may be operated. The sleeve 16 is provided With a peripheral flange 17 to facilitate turning the same and also serving to ornament the device. The outer end of the sleeve 16 is threaded as at 1S and threaded thereon is a member 19 having a lug 2O to engage an aperture 21 in the socket member 15. n using the. device the member 19 is retracted upon the sleeve 16 and the pole adjusted to the proper length. The sleeve 16 is then turnet. to lock the portions l and 2 and ,the members 19 turned upon the sleeve to l engage the socket members., and force the of each of the end sections for locking said stantially as described.

2. In a curtain pole, a central tubular section, a pair of end sections telescopng thereinto, the Y inner ends of said end sections being longitudinally split, rusto-conical members projecting into said split ends, a rod'ixed to each of said members'and extending through the respective end sections, saidrods projecting beyond the ends of the sections and threaded, members threaded upon the projecting ends of said rods, the outer ends of the last said members being exteriorly threaded and support engaging members threaded upon said ends, substantially as described.

ln testimony whereof I have signed my name tov this specification in the presence of two subscribing witnesses.

HENRY A. ANDERSON.
