Chris found this pic of a N&W loco i read that a lot of the early electric locos used this arrangement for the motor mounting

Thanks for that picture Jim,,, where do you find them???
Yes the BIG electrics as you commented had big wheel arrangments and connectors, so did some european `s
The had the best pulling power (Traction)

Here is a drawing of a Swiss counterpart I found. When they built the first electric locos, power transmission with connecting rods was easier to construct than direct wheel drives. (With rods it was the well known technique of the steamers.)

BTW: The pipes along the side were an oil cooler for the transformators.

Cool looking art work. Is that the motor batween the driving wheels?
Thank you for sharing.

Bud,

between the two driving wheels is a so called 'blind axle' . On both ends is a large cogwheel (the gray disks) with the pin for the connecting rods to the wheels.

The cogwheel itself is driven by two motors each. You can see the two rounded covers of the pinion gears, in the upper part of the oddly shaped grey boxes between the driving wheels.

Those boxes surrounding the big cogwheel are oil containers for the lubrication of the gears. The oil level was at the same height as the lowest teeth of the cogwheel, so that they just touched the surface of the oil sump. A somewhat messy, but very easy and reliable lubrication system.
