Today in 1968, US Patent D210566 S was issued, an invention of Frederic C. Jay, for his “Keg Cradle.” There’s no Abstract, and in the description there isn’t much beyond the self-evident claim that it’s a keg cradle.

FIG. 1 is a perspective view of the keg cradle embodying my new design, the keg being indicated in broken lines for illustrative purposes only.
