Today in 1904, both US Patent 767960 A and US Patent 767961 A were issued, and both are related inventions of William J. Ruff, under the same name: “Pasteurizer.” There’s no Abstract, although in the description it includes these claims for the first one:

My present invention relates to an apparatus for pasteurizing. beer, one of the principal objects of my invention being to simplify the construction and cheapen the cost of the apparatus, as well as improving its efficiency, by dispensing with a tank through which the bottles of beer are carried to expose them to the different temperatures to wit, in first at temperating the beer, then heating it to the maximum temperature, and finally cooling it to approximately atmospheric temperature.

And here’s a description of the claims for the second patent:

The object of my present invention .is to produce a pasteurizer wherein the bottles of beer are submerged in a water-bath during the time that they are subjected to the maximum temperature, while the preliminary heating and final cooling of the beer is effected without having the bottles submerged in the bath, the result being that a comparatively small amount of waterY is necessary to accomplish the work of pasteurization.
