Abstract

433,498. Window blinds. KINSEY, D. S., Corner House, Commissioner Street, Johannesburg, South Africa. July 24, 1934, No. 21644. [Class 52 (v)] A window screen of resilient sheet material is attached to a rotatable roller and slides in slots in frame side members, and has means for maintaining a restraining force on the unrolled end of the sheet in all positions thereof. A metal frame 2, 3 carries a roller 4, 5 on brackets 6, a rectangular sheet of wire gauze 7 being wound on the roller. The free end of the sheet 7 is stiffened by a bar 9 and the edges of the sheet slide in slots 10 in the side members 3 of the frame. The roller has conical end portions 5, 5<1> round which are passed flexible cords 12 secured to the rollers and to bar 9 at 14, and the cords which pass round pulleys 17 maintain the sheet under a constant tension when it is raised or lowered by the handle 16. In a modification, not shown, the roller has cylindrical end portions and a cord is secured to each end portion and wound thereon in opposite directions and passed over pulleys, the bar 9 maintaining a tension on the sheet by its gravitational pull and frictional engagement at the sides.
