Abstract

1,218,827. Window balancing devices. D. J. DINSMORE CO. 14 March, 1968 [17 July, 1967], No. 12528/68. Heading E1J In a spring balancing assembly for a sliding window a double pulley block 24 forms a floating anchor for one end 22 of the extension-compression spring 21 the other end 20 of which is secured through strip 15 and end plug 12 to a sash, as by screws through holes 14, the block 24 comprising a frame in two similar parts 40, 41 each carrying a shaft 42, 43, which shafts when the parts are placed together and held by a frame 50, 51, 52, Fig. 5 are at equal acute angles with opposite sides of the frame and are thus oriented transversely with respect to each other and staggered vertically of the frame, the floating anchor being connected by cable 33 to a fixed anchor formed by a second pulley block 25 having a housing 53, 54, 55, 56, Fig. 4, in which a single shaft 32 is transversely disposed and carries two pulleys 30, 31, held in place by a wire axle hanger bracket 58 engaging in grooves 57 on the axle 32 and engaging with its hooked ends 59, 60 in notches 61 in the fixed anchor 25, the walls 54, 55 having scalloped edges to cooperate with the flanges of the pulleys 30, 31 in retaining cable 33 from becoming disengaged from the pulleys and the wall 56 being likewise cut away to allow the pulleys to be mounted on the shaft 32. Cable 33 at one end is secured to the frame 50 and passes downwardly and secured around the pulleys of both blocks 24, 25 and after passing through channel 62 and a bore in the shaft 32 is secured at its other end to a bolt member 35. The U-shaped channel 11 has depressions therein to eliminate lateral movement of the coil 21 but allows twist of the coil and rotation of the floating anchor 24.
