Abstract

811,385. Machinery safety devices. UDAL Ltd., J. P. Aug. 20, 1957 [Aug. 23, 1956]. No. 25746/56. Class 80 (4). A safety device for a machine comprises a platform 4 arranged adjacent the danger area of the machine which when depressed by the weight of a person renders the machine inoperative. The platform is pivoted at one end on a spindle 5 whilst at the other it is supported by springs 6 to maintain a contact 8 clear of a switch mechanism 7 in the clutch and brake circuit of, for example, a power press. When the platform is depressed the switch 7 is actuated to render the machine inoperative. More than one platform may be provided, each of which controls a switch in the control circuit of the machine.
