Improvements in and relating to Machines for Making Lace and other Fabrics.
3146. Hickton, C. Feb. 9. Lace machines. - Mechanically-operated time and output recording-apparatus for use in connexion with lace and other textile machinery, as described in Specification 3145/09, is controlled by a series of three ratchet-wheels driven by a suitable part of the machine. The pin 7 of the second wheel i raises at each revolution the flexible arm z of a bell-crank, which, when returned by a spring, forces a pencil against a travelling chart and thus records each rack completed. The same chart records the running time, an horizontal bell-crank 12 being operated by a cam 8 moving with the first wheel a and causing a zigzag line to be drawn while the machine is running; a straight line is drawn while the machine is stopped.
