CURTAIN-SUPPORTING STRUCTURE.

Application filed December This invention relates to an improved ourtain supporting structure adapted to support divided draperies upon opposite sides of a window in such a manner as to be capable of being'turned into normal position in front of the window or to be rotated into position away from in front of the window as well as to be removed from normal position whereby the curtains are supported above the window, and replaced in'lowered position so as to be held inlowered position during the removal and replacement of curtains. q

One object of the invention is'to provide a structure of the character describedcom-i prising independently movable curtain sup-.

ports located upon opposite sides of the w-indow', which supports may be each removably held in normal curtain spppporting position- -01 moved into and held i lowered position to facilitate removal and replacement of the curtains. i

Another object of the invention is the provision of means whereby eachof the curtain supporting arms may be readily located in the proper angular position with respect to its shaft and with respectto the remaining curtain supporting arms whereby the straight portions of said arms will be positioned in parallel relation to each other and held in proper position relative to each other and the shaft when the holding means therefor are tightened. I

A further object of the invention isto provide an indexing means for-adjusting the angular position of the supporting shaft, to compensate for variations in the support ing arms upon opposite sides of the window and permit the proper alignment of the curtain supporting arms upon opposite sides of the window.

Referring to the drawings Fig. 1. is a front elevational view of a window casing showing the position of the curtain supporting structures upon opposite sides thereof,

In the embodiment of the invention illus trated herewith l designates the top portion and 2 the side portions of a window frame of the usual form. The curtain support comprises duplicate structures located adjacent to theside portions 2 of the frame, the ele-. I

ments of the duplicate structures located upon opposite sides of the frame are similar in all respects and the same reference char acters will. be used to designate corresponding elements of the structures.

Each of the duplicate curtain supporting structures comprises a vertical shaft or rod 3, provided with spaced reduced portions 4 and 5 formed thereinfora purpose which will be more fully described hereinafter, andhaving theupper and lower ends thereof threaded as indicated at 6 and 7. The upper end portion of each shaft 3 is inserted in a bearing opening 8 formed in an upper bracket 9, which may be secured to the top portion 1 of the frame by a screw or other suitable fastening device 10. A. lower bracket 12 is provided to assist in supporting the shaft 3 and comprises a portion 13 engaging the'side portion 2 of the frame and secured thereto by screws 14 or similar fastening devices. An upper arm 15 pro j'ects from the portion 13 of the lower bracket, and a lower arm 16 also projects therefrom, being located directly below the upper bracket. When the shaft 3 is in its normal curtain supporting position as shown in Fig. :1, it is supported: by having its upper end portion inserted in the bearing open ing 8 in thetop'bracket and its lower endpor-v tion inserted in'a bearing opening 17 formed in the lower arm 16 ofthe, lower bracket.

minares short o'fthe shaft 3 when the shaft is in its normal curtain supporting position as above described.

Curtain arms 19, and 21 are carriedby each shaft 3 being secured thereto and located relative to the shaft and each other after the manner now to be described.

A supporting nut 22, which is provided upon its upper face with a definite number of regularly spaced teeth 23, is threaded upon the upper end 6 of the shaft and sopositioned that one of the teeth 23 is properly located relative to the shaft. A nut 24% which is threaded on the shaft in advance of the nut 22 is then threaded up into clamping engagement with the nut 22' to'clamp the nut 22 securely in position and hold the same against movement. Each of the curtain arms 19, 20 and 21, is provided with a portion 25 bent to surround the shaft 3 which portion is provided upon its opposite sides with teeth 26 adapted to inter-fit with the teeth 23 of the nut 22 or is teeth of the portion 25 of the next adjacent arm. When the nut 22 is positioned in proper angular relation to the shaft the curtain arms 19, 20 and 21 may be placed thereon so that the teeth 26 on the portions 25 thereof int'erfit in such a manner that the straight portions of thecurtain arms arein substantially exact parallelism with each other and properly positioned angularly with respect to the shaft. The nut 27 is then threaded down into binding engagement with the portion 25' of the curtain arm 21 whereby the curtain arms are secured in position on the shaft 3. The curtain arms 19; 20 and 21 are provided with extensions 23, 29 and respectively which are adapted to slide over the straight portions of the curtain arms and may be adjusted on the arms to regulate the effective length of said arms whereby the arms may be adjusted to fit windows of varying width; Each curtain arm 19 and its extension 28 is adapted to support the usual lace curtain to the center of the window from each side; each curtain 20 and its extension 29 supports the drop curtain on one side of the window; and each curtain arm 21 and its extension 30 supports a divided valance extending from one side of the window to the center thereof.

In applying the structure to a window the upper and lower brackets are secured in place, and, after thecurtain arms have been secured to the shafts the upper end of each shaft is inserted in the bearing opening 8. of the upper bracket: and forced upwardly a sufficient distance toe nable the lower end of the shaft to be inserted in' thelbearingopein ing 17 in the lower arm of? the? lower bracket; The i metal around; the? bearing opening 8" is forced-r upwardly to; for-1111a flange- 31 extending:- around the: bearing The lower armilti ofthe lower bracket is provided with a bent up portion 33 and an indexing member 34 is positioned upon the upper face of the arm 16 being adj ustably secured thereto by a bolt 35 passed through a slot 36 in the indexing member and an opening in the bent up portion 33, the bolt being held in adjusted position by a nut fitting within the lower part of the bent up portion 33. The indexing member 34: is provided with a bearing opening 33, adapted to register with the bearing opening 1'? in the lower arm 16, and is provided upon its up per face with radiating grooves 39 adapt d to receive a pin 46 carried by the shaft In applying the curtain supporting struo tu're to a; window it is desirable that h corresponding curtain arms on opposite sidesof' the window bein substantially exact alignment when the parts are in operative position as shown in 1. In order to accomplish this the nut 22 having teeth 23 carefully adjusted on the shaft and the curta in arms provided with teeth 26 so positioned-thereon that the straight portions of the curtain arms may be parallel with the window when the pin is located in the proper groove 39. It may be however, that the nut 22 will not be positioned angularly of the" shaft at tlle exact point for accomplishing this object, in which case the necessary adjustment may be made by loosening; the'bolt 35- and turning the indexing member 34 slightly about the shaft 3 to lung the curtain arms on opposite sides of the window into exact alignment. The bolt 35 may then be tightened and the indexing member thus clamped to the lower arm 16 to hold the curtain arms in aligned position.

The upper arm 15 of the lower ln'achct member is:pro'vidcd with a bearing o en" c 40 having a narrowed slot 41 cominmiicating therewith; and the lower arm 16 of the lower bracket member is provided with a bearing" opening 42, in vertical align; with the bearing opening 40, and havi nar'rowed slot as communicating therei .i. lVhenit is desired to remove curtains from the curtain arms and replace them by others, the shafts 3 may be removed 111 the positions-shown in Fig. 1 by first rai ing the lower threaded ends 7 from the bearing openings 17 and then withdrawing the threaded portionsfi from the bearing openings 8 of the upper brackets. The reduced portions 4:} and 5 of the shafts i are then inserted in the slots 41 and 43 to position the shafts in thebearing openings i0 and 42-whe re they will -be supported within easy reach: to remove; orreplace the curtains; The curtain supporting structures may/then be: placed-m1 the positionsshown-in Fig. 1 asipfreviously described I111 order to prevent accidental removezh'ei the curtain supporting structures from the positions shown in Fig. 1, wing nuts 45 are provided which may be threaded upon the threaded portions 7 of the shafts to prevent the removal of the shafts from the bearing openings 8 and 1? until the nuts 45'l1ave been removed.

It is to be understood that the curtain supporting structures may be readilyturned by means of the pin46 to bring the curtains into position in front of the win dow or away from in front of the window, the pin as engaging with an appropriate groove 39 to hold the structure releasably in either of these positions.
