Emergency Stop for Electrically Driven ApparatusPatent No. 1,250,708, issued to Caswell D. Swett of Red-wood City, California, discloses a novel and apparently meri-torious emergency stop for electrically driven apparatus. Theobject of the invention is to provide an apparatus for in-stantly stopping electrically driven apparatus in the event of. accident or other emergency. The apparatus operates to re-verse the current through the motor so that it tends to rotatein the opposite direction or does rotate in the opposite direc-tion and opens the electric circuit on the initial reverse move-ment of the driven apparatus so that all movement of theapparatus is arrested. The apparatus consists of a polechanging switch in the motor circuit which is held in posi-tion to close the forward driving circuit by a latch and which is provided with^a spring for moving it to the reversedriving position when the latch is released. When the latchis tripped, the switch moves instantly into the reverse posi-tion, causing the motor to stop suddenly and reverse its di-rection, and thereby reverse the direction of rotation of thedriven element. The switch is connected to the drivenelement so that the instant that its direction of motion re-verses, the switch is moved to neutral position.
