Abstract
27,083. British Thomson-Houston Co., [General Electric Co.]. Dec. 12. Motors, controlling.-Relates to means for maintaining shunt-wound motors at constant speed irrespective of the load. A resistance is cut in or out of the armature circuit according as the load is decreased or increased. Figs. 2, 3, and 6 show the arrangement applied to a motor driving two machines or two parts of a machine, such as a linotype machine, in which it is important that a constant speed shall be maintained. On the shaft 2 of the motor 1 is mounted a pulley 3 driving one machine, and a second pulley 6 is carried by a sleeve 5 and adapted to drive the second machine. A. clutch 9 is adapted to be moved by a stud 16 to clutch the pulley 6 to the shaft. The arm 13 carrying the handle 16 is also connected to a switch arm 20 controlling a resistance 22. When the clutch is operative, the switch is closed and the resistance short-circuited, but, when the clutch is drawn out, the switch is opened. In controlling multiple machines separate clutches may be employed, each controlling a resistance.
