Abstract
174,441. British Thomson - Houston Co., Ltd., (General Electric Co.), Oct. 26, 1920. Stop mechanism.-A device for determining the time-interval elapsing between any two or more events such as the closure of a switch and the response of a relay thereto consists of a plurality of members 15, 15', 15" frictionallv mounted on a shaft 11 driven at a constant speed by means of a motor 12, and means for stopping the members in response to changes in electric circuits. Each member is provided with a dial graduated in hundredths of a second, and indicating pointers 25, 26, carried by the members 15, 15', indicate directly on the scale the time interval between the stopping of two members. The means shown for stopping the members comprises electromagnets 18, 19, 20 and spring controlled pawls 17 secured to the armatures thereof and adapted when the magnets are energized to engage one of the notches 16 on the members 15, 15<1>, 15<11>.
