Abstract
Abstract A starter motor having an armature shaft that is connected to the flywheel of an internal combustion engine by mechanical driving connections to drive the flywheel from the motor. However, when the motor is to be driven from the engine this mechanical drive is disabled and a fluid coupling is rendered effective to convert the motor to a generator.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
212 words
In a motor vehicle including an internal combustion engine having a flywheel with a gear thereon and a starter motor including an armature shaft, a unit providing driving connections between said shaft and flywheel comprising: a. a casing including means for mounting the casing in said vehicle, b. a first stub shaft journaled in said casing and drivably connected to said armature shaft, c. an element of an overrunning clutch within said casing and drivably mounted on said shaft, d. a first turbine element drivably mounted on said shaft within said casing, e. a second stub shaft journaled in said casing and having a pinion on its outer end in driving relation to the flywheel, f. an element of an overrunning clutch on the inner end of said second stub shaft and cooperating with clutch element on the first stub shaft, g. a second turbine element drivably mounted on said second stub shaft within the casing in confronting relation to said first turbine element, and h. a fluid medium in said casing cooperating with said turbine elements, whereby the drive from the armature shaft to the flywheel is mechanical and the drive from the flywheel to the armature shaft is through the fluid coupling provided by the turbine elements and fluid medium.

Claim 8
Dependent Claim
30 words
The unit of claim 1 in which the casing comprises two parts clamped together with each part having a tubular portion, said stub shafts being journaled in said tubular portions.
Claim 9
Dependent Claim
21 words
The unit of claim 1 in which the armature shaft is joined to the first stub shaft by a spline connection.
