Abstract:

The object of this invention is to improve and further extend the electric motor driven change speed device shown, described and claimed in an application for patent filed by me October 15, 1921, Serial No. 50,784(patent #1,527,247).

In said prior application I disclosed an improvement in a change speed device which consisted in combining an electric switch controlling the motor with the operating connections or handle of said device, so that when said connections were operated to change the speed, the switch would be operated to cut out or slow down the motor and so that when the change was effected the switch would return to normal position and the motor to full speed.

In this present application, I have further improved or extended this idea by arranging the mechanism so that it can be used in combination with a motor connected to drive such change speed gearing, which motor is controlled by a magnetic starter and a starting and stopping push button station.
