Abstract
682,465. Punching-machines. DUNLOP RUBBER CO., Ltd. April 4, 1951. [April 21, 1950] No. 9819/50. Class 31 (ii). Apparatus for punching holes in flexible material comprises a punch 9 operatively connected to a plunger 2 associated with a solenoid 1 so as to be movable towards an anvil 11, against the action of a spring 31, when the solenoid is energized, the solenoid being arranged in a circuit comprising a main switch 38, Fig. 2, and an auxiliary switch 21, the latter switch being actuated to de-energize the solenoid, when the punch reaches a predetermined position in its movement towards the anvil, by means of a handle 16 on an extension 3 of the plunger engaging a lug 15 on a pivotally-mounted lever 12, the engagement of these parts also operating a piston and cylinder time-delay mechanism which, after a predetermined time delay, is adapted to actuate the switch 21 to re-energize the solenoid. The solenoid circuit also includes an actuating switch 24 mounted on an adjustable bracket 25 and adapted to be operated by the deflection of a hinged plate 28 when the article, eg. a rubber boot, to be punched is located on the anvil. Arranged in parallel with the switch 24 is a switch 40, Fig. 2, which when closed short circuits the switch 24 to set the machine for continuous automatic operation,
