delivered at all speeds
Throughout the entire speed range of 75 to 1300 r.p.m., the Sargent Cone Drive delivers full motor power, is vibrationless and silent, and assures con stancy of any selected speed. It is, therefore, as efficient for such applications as the rotation of electrodes and calorimeter paddles at speeds of about 200 r.p.m. or less, as it is for general stirring operations at higher speeds. Fine adjustment of speed is made by means of an adjusting nut which changes the effective diameter of the cone in con tact with the friction ring. Because the motor is a brushless, induction type not containing centrifugal switches, it is recommended as safe for use in the presence of inflammable vapor. The simple right angle clamp permits rapid adjustment of the mo tor to any desired position in horizontal and ver tical planes. S-76445 Sargent Cone Drive Stirring Motor. (Patent No. 1,973,576.)
