Today in 1974, US Patent 3843172 A was issued, an invention of Frederick F. Stevens, assigned to Hoff Stevens, for his “Keg Tapping Device Having Improved Sealing Means.” Here’s the Abstract:

A tapping device for beer kegs or the like includes a keg unit permanently or semi-permanently mounted on a keg and having a pair of passageways therethrough for receiving a pair of tubular probes associated with a tavern unit which is connected to the keg unit at a tavern or restaurant where beer is dispensed. The device includes a unitary elastomeric seal member carried by the tavern unit and surrounding the probes thereon. The seal member provides a gas and liquid tight seal between the tavern and the keg units when the two units are assembled in connected relation. Means is provided to limit compressive force applied to the seal member by connection of the units so that it retains its sealing integrity even after prolonged usage involving repeated connection ,and disconnection.

By

patent-logo
Today in 1969, US Patent 3473556 A was issued, an invention of Edward G. Akers, Keith M. Johnson, and Robert P. Marine, for their “Beer Keg Tapping Device and Seal.” There’s no Abstract, although in the description it includes this summary:

The disclosure herein describes a novel seal and more particularly a new beer keg tapping device. The beer keg tapping device described herein includes a tapping valve and an outer fitting with the tapping valve having a beer passageway extending therethrough. The passageway has an outwardly flared portion adjacent the outlet thereof. The tapping valve is releasably secured to the beer keg and a valve element is movable axially within the beer passageway to selectively open and close the beer passageway. The outer fitting includes an elongated probe receivable within the outwardly flared portion of the passageway and engageable with the valve element to move the valve element to open the beer passageway. The probe has a beer passageway therein and a skirt-type seal adjacent the inner end of the probe. The seal is engageable with the outwardly flared portion of the beer passageway of the tapping valve and as the probe is moved axially, the skirt seal is cammed radially inwardly to form a very tight probe-to-tapping valve seal before the beer passageway is Opened. The tapping valve is secured to the beer keg by cooperating lug members on both of the keg and the outer fitting and by a pair of tabs driven through apertures in the tapping valve and engageable with projections or ribs on the keg.

Today in 1998, US Patent 5823222 A was issued, an invention of James Edward Minshull and Robert G. Lawrence, assigned to Labatt Brewing Company Limited, for their “Sanitary Sampling Device and Method for Using Same.” Here’s the Abstract:

A sanitary coupling device and a method for its use are described. The sanitary coupling device taps a vessel, such as a brewery tank, without exposing the fluid to the atmosphere. The device can include a coupler that prevents the collected fluid from exposure to the atmosphere. The method for tapping a vessel can include engaging a nipple with a coupler. Then, collecting a sample and disengaging the coupler from the nipple is performed. The invention is desirable for a brewery tank sampling with a clean-in-place connection system.

Today in 1959, US Patent 2909044 A was issued, an invention of John F. Wilcox, assigned to Superior Products Mfg Company, for his “Spout Cooling Apparatus.” There’s no Abstract, although in the description it includes this summary:

This invention relates to liquid coolers and dispensers and more specifically relates to apparatus for cooling liquid dispensing spouts or faucets.

This one’s interesting and worth the long read. It’s essentially adjunct brewing, but incorporating soybeans in the process, too. The fact that Archer Daniels Midland owns the rights to the patent is also a bit curious.

Patent No. 4355047A: Method Of Preparing A Low Calorie Beer

By

patent-logo
Today in 1982, US Patent 4355047 A was issued, an invention of William F. Line, Vinod K. Chaudhary, Etzer Chicoye, and Robert J. Mizerak, assigned to Miller Brewing Company, for his “Method of Preparing a Low Calorie Beer.” Here’s the Abstract:

Low calorie beer is prepared by introducing into the brewing process a debranching enzyme (pullulanase) obtained from rice, a traditional brewing material. The debranching enzyme reduces the real extract of the beer by cleaving alpha 1,6 linkages of unfermentable limit dextrins to form alpha 1,4 dextrins which can be converted by alpha 1,4 carbohydrates to sugars that can be fermented by brewer’s yeast. The enzyme may be introduced into the brewing process by adding rice or the enzyme extracted from rice to the mash or to the wort before or during fermentation. The debranching enzyme may be obtained from polished dry milled rice by extraction with an aqueous buffer solution. When malted rice is used as the enzyme source a particularly useful mixture of the debranching enzyme and alpha 1,4 carbohydrates is obtained.
