Abstract
548,973. Channelling shoe soles. BRITISH UNITED SHOE MACHINERY CO., Ltd., RICKS, F., and PRATT, J. W. April 29, 1941, No. 5528. Addition to 525,408. [Class 31 (i)] Modifications are made to the power-driven cam for shifting the edge gauge, described in the parent Specification, and its actuating mechanism. The cam is readily removable so that it may be changed, and is reversible for the other shoe of a pair. The cam actuates devices to de-clutch its own drive at the end of a cycle and at one or more predetermined times in the cycle. Removal of the work engages the clutch to bring the cam to starting point if it is not already there. The clutch is closed by mechanism operated by hand, and is opened automatically when it is required to stop the cam rotating.. The cam 25 is carried by a block 29 driven by reducing gearing 47, 49, 53, 55 from a clutch 67 adapted to be driven by a pulley 75. The cam is positioned by a spring plunger 31 and is held in place by a collar 43 secured to the block by a bayonet coupling. The clutch is urged to closed position by a spring 99 and is freed by a push-rod 95 actuated by a lever 105 linked to a lever 121 carrying a wearplate 125 co-operating with a similar plate 133 on an arm 127 pivoted to a lever 131. The arm 127 is actuated by a latch 153 when a hand lever 149 is depressed to start rotation of the cam. The lever 131 is swung counter-clockwise to free the clutch when a pin 141 engages a wedge 139 on the lever at the end of the cycle. The clutch is also freed when any one of five pins 161 slidable in the block reach the wedge 139 unless the cam has an opening in line with a pin. If the particular cam in use has not completed one rotation at the end of the machine's cycle, the depression of the work support at the end of the cycle engages the clutch by mechanism connected to a slide rod 169. Specifications 25730/06 and 13052/08, [both in Class 31], also are referred to.
