In the embodiment of the invention illustrated herewith 1 designates a curtain supporting member which comprises a pair of hollow channel shaped telescoping sections 2 and 3, the section 2 being of slightly less cross sectional area than the section 3 whereby it' is enabled to slide readily therein and thus form an extensible supporting member as fo supporting and housing the necessary is a front elevational View of the be oppositely positioned to each other in a substantially vertical plane when in operative position, and to provide a substantially continuous longitudinal slot 6 extending hroughout the major portion of the curtain supporting member. A filler plate 7 is see cured to that end portion of the telescoping section 3 which is located at the left as seen.

in Fig. 1, and the filler plate 7 has a portion 8 oii'set slightly from the main body portion thereof to lie within the end of the slot 6. A pin 9 is passed through the end portion of the telescoping section 3 and the filler plate 7, and serves to hold the filler plate firmly secured to the end of the telescoping section and at the same time rotatably support a pulley 10 mounted within the channel formed in the telescoping section. The pulley 10" is provided with a pair of oppositely positioned surface grooves 11 and 12 for a purpose which will be more fully described hereinafter, and has a fin 15 located intermediate the grooves 11 and 12, the fin being of sufiicient diameter to extend substantially entirely across the major axis of the channel.

Theouter end of the telescoping section 2 is provided with a filler plate 18 secured thereto by means of a pin19, the filler plate 18 being provided with branched ends. 20 shaped to fit partially about the outer sur face of the telescoping section 2 whereby'the outer ends of the telescoping sections 2. and 3 are all substantially the same size to fit snugly within the lateral recess formed in a common bracket member. The pin 19 has a sleeve or pulley 21 mountedthereon to receive' the operating cords for controlling the movement of curtain carriers.

Bracket members 22 of a similar character are provided for supporting the outer ends of the telescoping sections 2 and 3, each bracket member being provided with a base 24 for attachment to a portion of a window frame and having an outwardly projecting support 25 provided upon one side with a lateral recess 26 shaped to receive the outer end portion of one of the telescoping sections. A curtain supporting anchor plate 27 is provided with a depending portion 28 for attachment to the edge of a curtain and is secured to the projecting support 25by means of a screw threaded holder 30, whereby the outer edge of each curtain may be fixedly anchored at a point adjacent to and in substantially vertical alignment with each bracket member, and thus the outer edge of the curtain may be securely held at all times in its appropriate position relative to the edge of the window frame. The outer end of the telescoping section 2 is provided with an opening 31, and the outer end of the tele scoping section 3 is provided with a similar opening 32. l/Vhen the end of one of the telescoping sections is positioned within the recess 26 formed in the support 25 the application of the fastening screw 30 to the support not only holds the curtain supporting plate 27 in position upon the bracket but the end of the fastening screw 30 enters the opening 31 or 32 and thus serves to firmly secure the outer end of one of the telescoping sections to the bracket member.

Positioned within the channel in the cur= tain supporting member are a plurality of curtain carriers comprising master carriers 36 and 37 and intermediate carriers 38. The intermediate carriers 38 each comprise a curtain supporting plate 39 having a depending portion 40 provided with an opening 41 whereby the same may be attached to a portion of a curtain. An oflset grooved or channeled traveler block 42 is secured to the main portion of the supporting plate 39 in any suitable manner as by being riveted or otherwise firmly attached thereto, and the traveler block 42 is provided with a circumferential groove 43 adapted to receive the inbent edges 4 and 5 of the telescopingfsection whereby the traveler block will ride upon the lowermost inturned edges and be guided by the uppermost inturned edges as it is retained in position within the slot 6 by the opposed inturned edges of the supporting member. A guard plate 44 is pivotally mounted upon a portion of the traveler block 42 and located adjacent to the plate 39, which guard plate is provided with oppositely positioned inturned wings 45, so proportioned as to extend substantiallyacross the channel 6 and thus serve to maintain the adjacent carriers 38 in position of proper separation from each other and prevent them from becoming jammed.

The master carrier 36 is located inwardly of the intermediate carrier members 38 which are positioned at one end of the curtain sup porting member, and is provided with a depending plate 48 provided with an opening 50 for attachment to the innermost edge of the curtain section located upon that side of the window. The master carrier 36 is provided with an offset traveler block 51 secured to the depending plate 48 in any suitable manner as by being riveted or otherwise secured thereto, and the'traveler block 51 is provided with a circumferential groove 52 adapted to receive the inbent edges 4 and 5 of the telescoping sections 2 and 3 respectively. An enlarged guide plate 53 is formed integral with or secured to the traveler block 51 and positioned within the channel of the supporting member, the guide plate 53 havinga diameter sufiicient to extend substantially entirely across the major axis of the channel. A transverse opening 54 is formed in the traveler block 51 outwardly from the guide plate 53 to receive the cord 60 and a set screw 55 is threaded in the traveler block 51 and engages the cord to bind the carrier member 36 firmly thereto.

The master carrier member 37 is located inwardly of the intermediate carrier members 38 upon the opposite end of the curtain supporting member from the master carrier 36, and is provided with a depending plate 61 having an opening 62 formed therein for attachment to the innermost edge of the curtain section located upon that side of the window. Themaster carrier 37 is provided with an offset spindle 63 having an enlarged head 64, and a traveler block or sheave 65 is mounted on the spindle 63 and offset from the depending plate 61. The traveler block 65 is provided with a circumferential groove 66 adapted to receive the inbent edges 4 and 5 of the telescoping sections 2 and 3 respectively' The traveler block 65 is provided with an enlarged guide plate 67 which is of sufficient diameter to extend substantially entirely across the major axis of the channel. A transverse opening 68 is formed in the enlarged head 64 of the'spindle 63 to receive the cord 60, and a set screw 69 is inserted within the sleeve 63 to engage the cord 60 and bind. it firmly to the spindle 63.

It will be noted that the cord 60 is connected to the spindle 63 inwardly of the guide plate 67, while in the master carrier 36 the mounted upon the sleeve 63, but it may be non-rotatably secured to the sleeve or the depending plate 61, or the traveler blocks 42 and 52 may be rotatably mounted relative to their depending plates 39 and 48 respectively, if desired. i

The telescoping section 3 is provided with oppositely positioned openings 70 and 71 located adjacent to the pulley 10 through which the ends of the cord 60 may extend to be positioned within easy reach of the operator for adjusting the curtains.

In assembling the parts to form the curtain supporting unit, which is located between and supported by the brackets 22 when in operative position, one end of the cord 60 is passed through the opening 70 or 71 in thetelescoping section 3, dependent upon which side of the window it 1s desired that the cord ends depend for operating the curtains. The cord end passed through the opening 70 or 71 is then passed over one of the grooves 11 or 12 formed in the pulley 10, in the present instance over the groove 11 as shown in Fig. 3 of the drawings. The desired number of intermediate carrier members 33 for attachment to one of the curtain sections are then inserted in the telescoping section 3, and the cord 60 is passed through the opening 68 in the spindle 63 of the master carrier 37, and the master carrier 3'? likewise inserted in the telescoping section 3. The cord 60 is then passed into the open. end or" the telescoping section 2 and around the sleeve or pulley 21 carried by the pin 19, and the end then brought back towards tne telescoping section 3. The desired number of intermediate carrier members 38 for application to the other curtain section then inserted in the telescoping section 2, and the returning cord end passed through the opening o l in the traveler block or a master carrier 36, the master carrier 36 being then placed in the telescoping section 2 inwardly of the intermediate carrier members as shown. The end of the cord 60 is then brought back into the interior of the telescoping section 3 and passed over one of the grooves in the pulley 10.; in the present instance over the groove 12, and then out through the opening 70 or 71 with the other cord end. Theinner ends of the telescoping sections 2 and 3 are then interiitted with each other and forced together until the complete overall length of the curtain supporting members is substantially equal to the dis tance between the brackets 22. The lower ends of the depending plates 39 upon each side of the supporting member are secured to one curtain section at substantially equal intervals and each master carrier 36 and 37 has its depending plate secured to the innermost edge of one of the curtain sections. The curtain sections may then be arranged in their extended positions before the window and the set screws and 63 then threaded in against the cord to properly locate the positions of the master carriers on the cord when the curtain sections are fully extended. The opposite ends of the curtain supporting member may then be inserted in the lateral recesses 26 oi the brackets 22. the outer edge of the curtain section secured to the holding plates 27, and the screws 30 then inserted to bind the holding plate 27 and one end of the curtain supporting member 1 firmly in position within the recess 26 of the bracket memher.

The parts being thus secured in position with the opposite ends of the cord 60 depending from one endof the curtain supporting member through the opening 70 or 71, a pull member or weight 72 may be attached to each end of the cord to facilitate the operation of the parts.

lVhen the telescoping sections 2 and 3 have been interfitted together with the carrier members 36, 37 and 38 all in position within the slot 6 the structure thus formed consti- I tutes what may be termed a curtain supporting unit, wherein all of the operating parts are retained in position for use at any time Without change, merely upon the application of the unit to a pair of brackets. The tele scoping character of the curtain supporting "or from each other.

The provision oi the oppositely positioned openings 70 and 71 in the telescoping section 3 makes it possible to apply the curtain supporting unit to a window in such a manner that the ends of the operating cord may be actuated from either side of the window by merely reversing the curtain supporting'unit end for end and threading the cords so that they will pass through either one or the other of the openings 70 and 71.

By means of he pulley 10 provided with the central in 15 which extends substantially across the major transverse length of the channel and by constructing and arranging the guide members 53 and 57 so that the portions of the cord 60 to which they are attached are located substantially on opposite sides of the channel, those portions of the cord which lie within the channel are substantially separated from each other so that free movement of these portions of the cord is insured and the cord is prevented from becoming entangled with any of the operating parts during the operation of the mechanism. I

The traveler blocks 42, 52 and are all positioned within the slot 6 in such a manner that the int-urned edges eland 5 of the telescoping sections 2and 3 respectively project within the grooves formed in the traveler blocks whereby the several carrier members are all maintained in proper operative position at all times and easy operation of the curtains is secured by reason of the fact that these traveler blocks travel upon one of the inbent edges of the curtain supporting member while at the same time being guided and maintained in position at all times by the other of said inbent edges.

The provision of the anchor holding plates 27 carried by the brackets 22 insures that the outer edge of each curtain section be maintained at all times in proper position relative to the edge of the window and overcomes the tendency to form a gap between the curtain and window frame which would be present in the structure if the outeredge of the curtain was secured to one of the movable carrier members 38.

The provision of the filler plates 7 and 18 with the portion 8 offset to fit within the slot 6 and the portion 20 fitting over the outer surface of the telescoping section 2 respectively, result in rendering the end portions of the telescoping sections 2 and 3 of substantially the same size externally so that they will fit closely within the recess in either bracket member and thus permits the ready interchange of the curtain supporting member end for end whenever it is desired to change the same to permit operation of the curtains from one side or the other of the window, and at the same time the provision of the filler members serve to close the ends of the slot 6 and retain the curtain carrier members against separation from the curtain supporting member.
