Abstract

539,246. Motor controllers. RAMSDEN, H. K.. KETTLEWELL, H .N. W.; and METROPOLITANVICKERS ELECTRICAL CO.. Ltd. March 8, 1940. Nos. 4402 and 10110. [Class 38 (iii)] A lever 8 actuating the controller of a trolley bus is operated by a pedal 9 through a spring link 12 and is retarded by a piston 4 working in a cylinder containing oil. Until the motor current reaches normal accelerating value, a valve 26 is open and controller moves freely. After the valve 26 is closed the controller is moved slowly. When the motor current reaches an upper limit valve 19 closes and the controller then only advances very slowly, this advance allowing the motor to accelerate on hills. Quick return of the controller is permitted by the valve 24. To prevent the valve 26 closing due to heavy regenerative current, a polarizing coil 45 can be fitted thereon. To adjust the setting of the valve 19 according to field current it is controlled by a relay 37 subjected to both armature and field current.
