Patent No. 3637117A: Keg Tapping Device

patent-logo
Today in 1972, US Patent 3637117 A was issued, an invention of Mack S. Johnston, assigned to Republic Corp., for his “Keg Tapping Device.” Here’s the Abstract:

The device comprises a keg adapter mounted about a keg opening and a dispenser coupler releasably coupled to the keg adapter having gas inlet and beer dispensing outlet passages terminating in two side-by-side probes depending from the coupler. The liquid probe is movably mounted in the coupler and biased in one direction. An inverted J-shaped tube is carried by the coupler in communication with the liquid probe and displacement of the tube moves the liquid probe in the opposite direction to open the beer valve in the keg adapter. The gas passage is in communication with a hand operated portable plunger-type pump whereby gas is provided through the keg adapter into the keg.

Patent No. 3636888A: Pallet

patent-logo
Today in 1972, US Patent 172687 A was issued, an invention of John A. Angelbeck Jr., assigned to Pack Rite Packaging & Crating, for his “Pallet.” There’s no Abstract, but it’s described as a “pallet used for the storage and transporting of containers such as beer kegs and the like.” It’s essentially a plastic pallet, and while I’ve seen a few of them, I don’t think they’ve replaced the wooden pallet the way the inventor hoped.

Patent No. 172687A: Improvement In Beer-Coolers

patent-logo
Today in 1876, US Patent 172687 A was issued, an invention of Louis Baeppler, for his “Improvement in Beer-Coolers.” There’s no Abstract, but the description includes this:

My invention relates to an apparatus which maybe readily applied to a keg or barrel of any description, so as to cool the beer after it leaves the barrel.

The invention consists of an ice-chamber, provided with an opening at the bottom for the insertion of a cock to be attached to the lower end of the cooling-coil, and an opentopped slot at the top for the insertion and removal of the upper end of the coil, and a cover for closing said chamber, as hereinafter described and shown.

Patent No. 2028283A: Foam Controlling Beer Faucet

patent-logo
Today in 1936, US Patent 2028283 A was issued, an invention of Jules Howard and Sanford E. Richeson, for their “Foam Controlling Beer Faucet.” There’s no Abstract, but the description explains that the “invention relates to beer and like taps or valves for drawing off foamy liquid from a cooler or other container.” It was designed “to prevent loss of the liquid incident to foaming in the glass after standing for some time in the cooler or container, and at the same time to regulate the depth of the head or cap of foam at the top of the glass.”

Patent No. 3933282A: Universal Tavern Unit For Keg Tapping Device

patent-logo
Today in 1976, US Patent 3933282 A was issued, an invention of Frederick F. Stevens, Jr., and assigned to Hoff-Stevens, Inc., for his “Universal Tavern Unit for Keg Tapping Device.” Here’s the Abstract:

A universal tavern unit for a keg tapping device comprises a basic tavern unit for connection to a keg unit permanently or semi-permanently connected to a keg. The basic tavern unit is adapted to cooperate with the keg unit to provide inlet and outlet passageways which communicate with the interior of the keg for the introduction of gas under pressure into the keg and the discharge of beer or other liquid therefrom. The universal tavern unit further includes a pressure relief check valve adaptor assembly for connection to the basic tavern unit to adapt it to the requirements of an associated beer or liquid distribution system.

Patent No. 1125735A: Keg Or Container

patent-logo
Today in 1915, US Patent 1125735 A was issued, an invention of Frank A. Schaum and Eugene F. Wales, for their “Keg or Container.” There’s no Abstract, but the description explains that the “invention relates to kegs or other containers and has for its object reinforcing devices for strengthening the container.” They continue. “A further improvement is devices for holding the hoops in place. These devices may be made part of the reinforcing structure.”

Patent No. 4720076A: For A Carbon Dioxide Gas Pressure Dispense System For Beer

patent-logo
Today in 1988, US Patent 4720076 A was issued, an invention of Roger J. Hyde, for his “Carbon Dioxide Gas Pressure Dispense System for Beer.” Here’s the Abstract:

A dispense tape (10) to control the flow of carbonated beers is configured to minimize pressure drop and turbulence in beer flow to an outlet nozzle (14) when open, the tap having flow restrictor means (52) operatively connected as a downstream extension of the tap valve (30), located in the path of beer flowing from the valve, arranged only to affect beer flow when the tap is nearly closed and configured to substantially restrict beer flow to maximize pressure drop and turbulence; choice of nozzle length/bore ratio enabling either a creamy flow or a squib of beer to be dispensed.

Patent No. US 2731027A: Beer Dispensing Apparatus

patent-logo
Today in 1956, US Patent 2731027 A was issued, an invention of Carl L. Daun, for his “Beer Dispensing Apparatus.” There’s no Abstract, but in the description, he describes as an “invention relat[ing] to [an] apparatus for dispensing carbonated beverages without there by changing the gas content of the beverage while eliminating the losses customarily encountered in dispensing such beverages. He continues:

This apparatus is particularly useful in dispensing beer from barrels but is, as will be apparent, suitable for all liquids. According to present practice barrel beer is dispensed from a faucet connected to a tap rod projecting to the bottom of the barrel through a tap which serves to provide a fluid tight seal at the tapping hole. Beer is forced up the tap rod to the faucet by the gas pressure in the barrel. A pressure regulated gas (air or carbon dioxide) source is connected to the interior of the barrel through a gas check valve in the tap. Theoretically such a system will maintain the carbon dioxide gas content of the beer constant and the drawing should be uniform. In practice, however, various losses attributable to variations in the gas content caused by temperature and pressure deviations from the ideal are encountered to a greater or lesser extent.
