Today in 1937, US Patent 2086832 A was issued, an invention of Charles Candee Green, for his “Dispensing and Storage Cabinet for Effervescent Beverages.” There’s no Abstract, although in the description it includes these claims:

I claim:

1. The combination in a beverage dispensing cabinet having an open front, a center-post at the front of the cabinet, and anelevated horizontal support rigid with the post and cabinet,

with a pair of oppositely opening hinged doors, of a tray extending substantially the combined width of the two doors and hinged to the cabinet above the doors, a prop pivoted on the cabinet adapted to rest on the support for holding the tray in open position, a stop-rib mounted on the under face of the tray, and rabbets on the upper edges of said doors for frictional engagement with the stop-rib when the tray and doors are closed.

2. The combination with an open-front cabinet having a center-post, and a pair of oppositely-opening hinged-doors, of a tray extending substantially the combined Width of the two doors and hinged to the cabinet above the doors, a stop-rib mounted on the under face of the tray to form a front edge-groove, and rabbets forming a complementary groove at the upper edges of the doors, whereby frictional engagement of the rabbets against the stop-rib holds the tray against opening movement when the tray and ‘doors are in closed position.
