extend over the cord when it is engaging the pulley.

Each plate is formed with one or more pressed out projections 53 for engagement with the tubular part l1 to space the master runners at their lower edges.

Each master runner is provided with a lug 54 at each side of the rollers 24, these lugs being bent to extend across ythe edge of the rollers at the leading and trailing edge ofthe master runner to prevent the rollers of the master lrunner fouling with the rollers of the ordinary runners.

The lugs-54 engage the ordinary runners, when the curtains are drawn apart, `to vlimit the extent to which the master runners can be moved towards the ordinary runners. If desired balls or rollers could be provided in place ofthe projections 53. p. v

In operation, one curtain is attached to the master runner mounted on the track at oneside of the rail and to a number of ordinary runners engaging both tracks, whilst the other curtain is attached to the master runner engaging the track at the other side of the rail and upon a suitable number of ordinary runners engaging both tracks.

d One master runner is 'secured to the upper run of cord by means or" a c ord clip, and the other master runner is secured tothe lower run of cord.

If required there may be two or moremaster runners vfor each curtain., the "number of such runners for each curtain controlling the amount of overlap, since the master runners'can pass one another as they engage the track at only one side of the rail and the curtains can be overlapped by a corresponding amount.

Operation of the cords in one or other direction moves the curtairi'towards orv away from one another, depending upon the direction in which the cords are moved.

The cord clip illustrated in Figure 5 .is formed 'from sheet metal pressed to form the tubular part 29, the neck and the head 28. A retaining' screw is mounted in a screw threadeddhole `39 in at opposite sides of the rail and along the upper edge of the lower tubular part 11.

runners engage both tracks so that they cannot pass one another and the curtains cannot be overlapped.

In a further modification illustrated' in Figure.

L8, the rail is constructed of a cross sectional shape which provides nearly the same resistance to bending on either side of the vertical plane passing through the web, so that the rail can be `bent as required without serious distortion.v

Tubular parts 44 and 45 are provided oneon either side of the vertical web 46, the tubular part 45 being at the lower edge of the web whilst the tubular part 44 is at the centre of the height of the web including the portion 47 for engagement Vwith the kattachment brackets. y v

In this construction the yrunners with a track constituted by a single horizontal flange 48 at theupper edgeiof the tubular; part 45, and each roller, is .mounted` upona hanger are each provided, with la single cylindricall roller engaging Ain a similar manner with the exception that the 'arm extending at the back of the web is projected upwardly as shown at 52 and is shaped to engage a cord clip secured to the cord in the tubular part '44. Such master runner would of course not be l Jcured one to-each of the leading edges of the two curtains, and whilst the curtains can be drawn together or moved apart by operation of the cords, thecurtains cannot bev overlapped, but the leadingv edges can only be drawn into abutting relationship. d l

In the modification illustrated in Figure 9, the rail is constructed'of section corresponding with that adopted in the construction illustrated in Figures 1 to 3,v except that the integral attachment flange 15'is' omitted, and the rail is provided on'the'ilpper' tubular 'part 12 with two integral ribs or beads 5'7 which extend longitudinallyl of the rail and are formed integrally therewith.

The rail is adapted to be mounted in position by means of brackets each of which is provided at its projecting end with a seat portion formed d upper tubular part 12 and the lower tubular part 11 are slotted on the same side of the rail instead of on opposite sides as in the previously described constructions.

In the slight modiiication illustrated in Figure `10, the rail is constructed with flanges 13 and 14 and longitudinal ribs 57 as described with Vreference to Figure 9, but Vthe tubular parts 12 Upon these tracks are mounted cylindrical rollers in place of the grooved rollers 24 in the con` struction illustrated in Figures 1-3. The master and 11 are slotted on opposite sides of therail.

In Figure 11 is illustrated diagrammatically the manner in which a number' of curtains can be moved into overlapping relationship, and it will be appreciated that two curtains 58 and 59 can be overlapped at their meeting edges by as large an amount as desired by providing two or moreA master runners at the leading edge of each curtain', these being mounted of course upon a rail of a form described with reference to Figures 1 lto 3 or Figures 9 and 10, enabling the desired overlap of curtains.A

The two edges of the curtain 58 may be moved in oppositeA directions so that, for example, the centre of the curtain located substantially` op- 'posite tofth'elwindow post 60 canv be anchored to the-rail, and each` edge of the curtain would then be drawn towards this post and to the centre or anchored position of the curtain.

In order to locate or anchor the centre of the curtainwith respect to a definite position on the rail', and to limit or stop the movement of the runners up to this position',v an anchoring stop of the form illustrated in Figure 12 may be-secured to the railas shown in Figure 13.V

Thisistop is formed from a strip of metal bent upon itself to form a double portion 61, and a pair of attachment arms 62, 63 disposed in spaced relationship for engagement with the flanges 13 and 14 at one side of the rail.

- The end of eacharm 62, 63 ris bent outwardly to form a retaining ange 64, and the stop is mounted in position as shown in Figure 13 by engaging these anges 64 behind the iianges 13 and 14. The stop is then locked in position by means of a stud 65 engaging in ascrew threaded hole in a pressed up boss 66 in the lower arm 63, the end of the stud engaging the underside of the arm 62 so that by suitable adjustment of the stud the arms 62 and 63 can be separated and` clamped upon the flanges 13 and 14 of the rail.

The stop may be secured to the rail at a po-v sition opposite'to the vertical post as illustrated diagrammatically at 60 in Figure 11, and the centre part of the curtain can be anchored to this stop which is apertured atv 67.

Thus, the curtain can be located with the stop which also projects across the flanges 13 and 14 and consequently forms a stop for *the runners upon Y,which the remainder of the curtain is mounted.

With a construction according to this invention a single rail can operate six `light curtains or a smaller number of heavier curtains, and move them simultaneously in any desired direction, some vfor example being moved in one direction, and others in the opposite direction, whilst if 4desired the two ends of the same curtain cany be `moved in opposite directions towards and away from one another. All such adjustments can be made with a single cord, and the master runners can readily be clamped tothe cord in any desired position by tightening the clamping screws 32 carried by the master runners.

The operating cords enclosed Within the tubular parts of the rail consequently cannot .get entangled with the supporting hooks Vor other portions of the apparatus, whilstY the appearance of the structure is substantially improved by the Vreduction in number of guide brackets necessary in the apparatus.

The rail can be bent without local distortion of the tubular parts for Ahousing the cords, and consequently the operation of the apparatus is facilitated since the tubular parts do Vnot become closed or opened at the bends and consequently the cords can be moved freely'around f the bends without tendency for the cords to move out of position.

A single length of rail may accommodate any number of pairs of curtains and permit some being moved simultaneously in an opposite direction to the other, it being understood that there will be at least one master runner and one cord clip for each curtain.
