Abstract
663,477. Machinery safety devices. LOTUS, Ltd., and WHITWORTH, W. Aug. 4, 1950 [May 18, 1949], No. 13195/49. Class 80 (iv) [Also in Group VIII] A clicking press (see Group VIII) is provided with two press button electric switches 161, 231 which are operated concurrently and so positioned as to ensure that both hands of the operator must be employed before the press can be actuated. In a modification, Fig. 5 (not shown), one of the switches is replaced by an arm which tends to maintain an obstructing position relatively to the other switch and which can only be moved by the band of the operator other than that used to manipulate the switch.
