They look a lot like Cissel dryers.

A local coin-op had them. A neighbor with a Maytag washer, and no basement like our house, did not like dryers, but during our winter monsoons when she could not hang out, she would wash up everything and drive up there to dry everything but the lares and penates. Of course she would set the temperature to the highest setting to dry fastest and cheapest. Unfortunately, the residual Tide not rinsed out by the Maytag yellowed the whites in the high temperature and we would have to hear about it on the next ride to school.
