Lou Costello invented the ice machine

Comment: My wife says that "Lou Costello" invented the Ice Machine and his family still holds the pattent to this day.

I think there's probably more than one kind of ice machine, but it appears this may have some validity; there's a photo for sale on e-Bay that is supposed to be of Lou Costello looking at the ice machine he designed.

I wonder if it made Abbotts Ice Cream?

A book by his son seems to mention that he put money into the development of an ice machine, but it doesn't say that he himself invented it.

Here are the pages which mention it.
