Another use for gas cartridges was in for aerating food products. Two inventors who

were working on these products in the 1930s were Marshall Reinecke and Henry

Snelling. Both assigned their patents to Food Devices, Inc., New York City. On June 14,

1935 Reinecke filed for his patent on a "Device for producing aerated expanded food

products." Among the products mentioned by Reinecke were whipped cream, ice cream

batters of all kinds, custards, and cheeses of the cottage cheese type. For aeration of

foods, gas cylinders were usually filled with nitrous oxide (N2O). Snelling applied for his

patent on September 11, 1937 and he points out that nitrous oxide is preferred but

"…any relatively stable gas having a high oxygen content and an ability to mix properly

with whatever food product is under aeration" is suitable. The design of his head took

on an appearance similar to Ward's soda siphon head.
