[Phono-L] Columbia Grafonola Electiric motor shutoff question

[Daniel Melvin]

Does anyone have any information on the rather complicated
geared switch mechinism on an electric Columbia motor? I have a machine
where that mechinism seems to have frozen up which was keeping the motor
from running. I took it apart and stared at it quite a lot and cannot even
figure out how it works. It has a bunch of gears and a cam that turns the
motor off and on.

To get the machine working I disconnected the gear attached to the tonearm
and rigged a manual switch for the motor. It works great, but I would really
like to restore the original switch mechinism if anyone has suggestions or
information on it. I have all the original parts, but the switch lost me in
the dust.

And, I thought Edison made complicated machines! This switch is amazing.

Thanks

Dan
