Juice Bar: 1928

Juice Bar: 1928

Takoma Park, Maryland, circa 1928. "Hendrick Motor Co. garage -- Battery Service." Another aspect of the establishment last seen here. 8x10 inch glass negative. View full size.



Above on the wall, obscuring the "R" in "SERVICE", appears to be a gas-fired distiller for (I presume) a source of pure water for the batteries. Also, peeking out behind the battery charging racks on the left, one spies the motor-generator that supplies the charging current.

Tar Pot

Thanks to Dbell for clearing that up, I thought it was a just a seriously hard core Coffee maker.

That appears to be a Dynamotor tucked in the corner of the bench, it's an AC motor turning a DC generator, probably the only way to rectify large amounts of current back then.

That tank

Needs a chain.

Fully equipped!

Lots to see here in this battery service shop, from the fire bucket (just in case), to the batteries stacked on the wooden steps - NOT on the shop floor (still believed to ruin a lead-acid battery.)

Sulfuric acid dispenser on one end of the bench, with a tar pot and (acetylene?) cylinder for heating it at the other.

And a really serious charging rack! With what appears to be a rotary converter to provide the 6+ volts for charging from the shop AC line.

And for your convenience --

In case of fire, use the handy bucket of water to toss onto the batteries.
