i’ve always thought this ice rink in oberstdorf, germany looked so magical to skate in, with those massive windows and the level ice, instead of being sunken down

Ever wonder about the incredibly cool “Ice Rink Resurfacing Machine” (aka Zamboni)?
We’ve got the patent! See all 124 pages in our Online Catalog (NARA ID 117724382).
Thanks to the Zamboni, the ice was smooth enough for this talented monkey! See Ice Skating Chimpanzee, 1963 (The Unwritten Record).
Excerpt from the release sheet:
SPORTS MONKEY SHINES! THIS CHIMP IS A GAY BLADE:
Usually, summer is the whacky season, but this winter things aren’t on an even keel in Germany. They’ve taught a Chimp to Skate and he’s a real swinger! After some tricks “Archibald” leads a Conga that proves he’s a real gay blade with quite a line figure-8-atively.
“Ice Rink Resurfacing Machine” Patent file excerpts:
PROBLEM: "The maintenance of a satisfactorily smooth surface on the ice is one of the major problems in connection with the operation of a skating rink… The squeegees have no effect on the hard-frozen rough ice, and the ice therefore remains rough 'until the next time that it is scraped."
BEFORE the Zamboni: "Heretofore, the usual method of cleaning off and smoothing the surface of the ice has been to send attendants out onto the ice to sweep off the cut ice with scrapers or sweeps that are pushed ahead of them; while in other instances, the ice is scraped clean by scraper blades mounted on towed sleds towed sleds or on automotive vehicles such as the small, four-wheel drive vehicles formerly used in the military services and known popularly as the jeep In either case, after the surface of the ice has 'been scraped clean, a thin film of water is spread over the ice to fill in the cracks and low spots, and surplus water is then squeegeed away, usually by a number of attendants on skates, pushing the squeegees ahead of them…
GOAL of ZAMBONI: "[An] object of the invention is to provide a self-propelled vehicle that can be operated by one man, and which functions automatically to shave the ice, convey the shaved ice to a large receptacle attached to the vehicle, and then squeegee a thin film `of water over the surface of the ice so as to provide a like-new surface when the water has frozen."
