摘要： 457,804. Roller-weighing apparatus for drawing, roving, &c. frames. KINNEAR, J. A., Redmyre, Invergowrie, Angus, and GOW, M. G., 285, Arbroath Road, and DUFF & CO., Ltd., T., Meadow House, Reform Street, both in Dundee. June 6, 1935, No. 16433. [Class 120 (ii)] The pressing - roller of drawing, roving, and like frames is pressed against the co-operating drawing rollers by a pair of levers 8 engaging the bearing- bushes of the pressing-roller 1 through a resiliently mounted bolt so as to apply pressure thereto in the position shown in Fig. 2, and adapted to be swung to the dotted line position 8 to relieve the pressure. The bolt passes freely through the lever and is engaged by a helical spring 9. The roller 1 is raised by depending hooks 11 from levers which, as shown, are the same as the levers 8, a toggle effect being produced by the hooks and the levers whereby the pressing roller is locked in the raised position. In the arrangement shown in Fig. 3, the lever 8 is weighted by a grooved weight 15 adapted to roll along a guide rod 16 when the lever is raised and so to assist the action. In the arrangement shown in Fig. 5, the lever is locked in operative position by a latch 19 and co-operating stops 21, 22 are provided to limit the backward movement.
