Remember a laundramat in Cocoa Beach,Fla that had the coin operated Bock spinner-The laundramat attendant showed us how to use the spinner-Remembered a mat like thing you put on top of the load in the basket before closing the lid and starting it.One woman didn't put the mat in the unit on her load-and it jammed the spinner and she was histerical running about the shop threatening to sue them for the loss of her things-For other patrons the Whirl-dry was out of service!Indeed the Bock saved time in the dryers.Also liked the sound of it-was thrilling to me as a kid-just liked running it.The fun part of the laundramat!Of course they don't have the Bock extractors no more.
