489,851. Elevated railways. SMART, L., ROBINSON, D., and PARKINSON, W. Jan. 28, 1937, No. 2511. [Class 104 (ii)] [Also in Group XIV] A railway for supporting curtains whereby bends or bays may be negotiated, comprises lengths of straight tubing 1 slotted at 2 on the underside, bent slotted tube sections 1a shaped at the ends 1b for ready connection to the straight tubes, rollers 14 arranged within the tubes and U-shaped brackets 3 for supporting the tubes both at the ends and intermediately. The tubing is provided with a strengthening rib 1c and the arcuate lengths 1a are expanded at 1b to take over the ends of the tubes 1, channels being provided to take the ribs 1c, The runners 14 comprise a pair of semicircular rollers one having a sleeve and the other a pin passing into the sleeve, which forms a bearing for a hanger 17 which may comprise a metal strip as shown or, for heavier curtains, a depending pin carrying a loose vertical roller or sleeve which bears on the edges of the slot to minimize friction. The end brackets comprise metal strips cranked at 6 to take a valance bracket 8 and bent at 11 to embrace the rod. A lug 13 bent downwards from the part 11 is apertured for a tape or cord attached to the curtain. The ends of the tube length 1 may be bent to slide into the end of an arcuate length 1a. Fig. 7 shows a switch whereby curtains may be slid selectively along two branches of slotted tubing connected by arcuate lengths 19, 20, e.g. for partitioning off hairdressers' establishments, comprising a pivoted bar 22 operated by a knob 23 to close one branch slot 20a and open the other. Selection of the branches 19, 20 when the curtain is being moved in the direction of the arrow A is effected by a pointed arm 21 operated by a lug 25 on the bar 22 engaging a notch 26 in the arm. Reference has been directed by the Comptroller to Specification 18743/12, [Class 104 (ii)].
