2,549,265	Apr. 17, 1951	Reversible split-phase motor	James l. Trant	Dayton, OH	"Split phase motors are well known and comprise a field having spaced windings therein, one of which is called the running winding and the other of which is called the starting winding. The motor is started by connecting the windings in parallel with a phase shifting reactance in series with the starting winding. This sets up a rotating field which drives the rotor in one direction, and there is usually provided a rotor mounted centrifugal switch which opens at a predetermined speed of the motor and interrupts the circuit through the starting winding. "Thereafter the motor runs as a straight induction motor, with only the running winding energized... Such motors are usually unidirectional, but by making the starting and running windings identical, they can be made to operate in either direction by placing the phase shifting reactance in series with one or the other of the said windings."
2,556,573	Jun. 12, 1951	Electric motor	Steffen S. Brown	Dayton, OH	Yet another scheme to lift the brushes and short the commutator bars of a repulsion-start induction-run motor. The objects of this invention are to make the mechanism less expensive, easier to assemble, more compact, and quieter.

Brown	Dayton, OH	"In many instances where electric motors are employed, the speed of the output shaft of the electric motor is too high for the work to be done. Under these circumstances, speed reducing devices are employed, sometimes directly associated with the drive motor and quite often taking the form of speed reducing gearing. "In the particular arrangement with which the present invention is concerned, a floor polisher unit is provided having an electric drive motor and connected thereto by speed reducing gearing is a polishing brush or floor working tool..."
