Today in 1963, US Patent 3076484 A was issued, an invention of Edward E. Tennant, assigned to Schlitz Brewing Co., for his “Beer Dispenser.” There’s no Abstract, but the application describes it, saying the “dispenser of the present invention is adapted for use with beer kegs or the like, such as are frequently used for party, picnic and other related applications where no regular beer dispensing equipment is available. The present device is of the general type utilizing gravity flow of the contained beverage which type of dispenser is highly desirable inasmuch as no hand pump or other pressure device is required to force the beer from the keg. The dispenser of the invention constitutes an improvement over gravity feed devices previously employed for dispensing beer.”
