Abstract

246,931. Smith, A., and Shackleton, G. W. Nov. 11; 1924. Letting-off warps.-In a friction brake device for a warp-beam, the movable weight 7, Fig. 2, is shifted along the balanced lever 8 by an equalarmed bell-crank 2, 5 so that the distance of the point of snspension d of the weight 7 from the spindle 9 of the lever 8 always equals the radius of the warp on the beam. The arm 2 of the bell-crank is held in contact with the warp by a spring 30. An arm 11 on the spindle 9 engages over a lever 12, which is supported at its centre on a rod 20 connected to an adjustable brak,echain 22 and is pivoted at its other end to a bellcrank 13 linked to a two-part bell-crank 16, 18. The bell-crank 16, 18 is connected to an adjustable brake-chain 23 at a point such that the pull on the chains 22, 23 is equal. The members of the bell-crank 16, 18 may be disconnected at 19 to put the brake-bands out of action.
