Retrofitting electric wall clocks for batteries  

I've retrofitted a retro...
I've retrofitted a retro electric wall clock with a battery mechanism. I'd say if its doable, no, you can't do it without completely removing the electrical parts inside (which is what I did). Else they will get in the way of the battery module, which has to be glued to the inside centre of the casing.

Isn't it funny, but
because I collect original Nelson clocks, if it's electric with a cord, I prefer to leave the cord showing. If I buy an electric clock that malfunctioned, I would replace the motor with a battery type, but the cord doesn't bother me.
I like keeping things original, whenever possible.

Great Clock
Brent Great clock! I have one like yours, in addition to a copper one. I too considered retro fitting, haven't gotten around to it. Seems tricky with this model as the motor is ecased in a metal housing with screws. If the battery can be externally placed...it's a doer. Also consider how this clock runs...one of the smoothest clocks around. Converting to battery might affect it.
btw...do you know this is a Henry Dreyfuss design?

I'm going to do it...
Thanks, Woof. These Ingraham clocks, as you know, have a little room inside the housing where one or two small batteries might fit. I also wonder how that would affect the operation of the clock. I own other clocks in this series that aren't wafers, so I'll experiment with one of them and post the results.
I do know that the clock was designed by Drefuss, or at least that's what I've read online. I bought mine several years ago and it was one of those pieces that awoke my love of mid-century design.
I have another Ingraham clock that's nearly identical--silver case, red second hand--except without the inner radiating circles. Do you know if that's also a Dreyfuss design?

I'm going to do it...Thanks...
Look forward to your results. Your right, batteries could be inside the case. However consider the nuisance of removing and reattaching the case. I've considered making a graceful cut out hole, as found on Vitras & Howard Millers. Even a cut out hole on the side/bottom. If successful, I may convert myself.
Haven't seen the clock you just described w/o the center radiating circles. Sadly, there's limited info on his clock designs outside the "Big Ben" series. You can see another wall clock design in his monograph "The Man In The Brown Suit". A really neat one for Ingraham, but I believe a concept or one off. The more I look at this clock, the more I love it!
