Electric motors for Victrolas

[Lenoirstreetguy]

We discussed these a while back and I knew I had an ad and I finally had some time to dig so here it is from The Literary Digest of Oct 21, 1916. Better late than never I suppose. This were the devilish little devices that made the owner run the risk of unhooking the spring. Too bad. They'd have been handy otherwise. I've never seen one in the flesh. If you enlarge the graphic you'll see an interesting line at the bottom " AGENTS Write for offer . The Arnold sells on demonstration. It is not sold by phonograph dealers. Ask us why!" Probably because of the spring thing!

Their claim is true that it "(p)ositively will not harm any machine" . . . . It will actually only negatively harm any machine!

I understand how it works -- basically a friction wheel that rubs against the turntable to make it spin....

...but, if you let the motor run down and then continue to spin the turn table, manually, won't that cause the springs to disconnect

I've never dared try this, so I don't know, for sure.

It's similar to this product:

They basically do the same thing. Except this one saves the springs (maybe)

Too bad the unit on Ebay is missing the "Victrola" male threaded attachment.

No, for the crank will spin round as the springs turn.

I've never had a problem with this, and I've used one of these motors for years on an Art Case Pathé Actuelle (one of the trapezoidal Tudor models with the crank inconveniently located INSIDE the cabinet).

I dont understand. The spring will unhook from the center arbor, and how will the crank spin around if the ratchet is working?

Isn't it true that for most spring driven phonographs the platter will spin on the spindle free of the motor (just relying on a little friction)? Could these electric motor accessories be based upon this?

The crank will spin in the direction of winding. Removing the crank from the machine may help to prevent the spring unhooking.

Of course, the electric turntable drive motor that we are discussing was primarily intended for use with Victor machines, which after 1918
use a specially formed spring end which fits into a slot in the arbor, and cannot come unhooked in any circumstance.

No, because the rim drive motor attachment has no governor, and so must rely upon the motor governor for speed control.
