Patent No. 4927335A: Pump For Transferring Liquids, In Particular Beer Or Carbonated Beverages

patent-logo
Today in 1990, US Patent 4927335 A was issued, an invention of Carlo M. Pensa, for his “Pump For Transferring Liquids, in Particular Beer or Carbonated Beverages.” Here’s the Abstract:

The present invention relates to a pump for transferring liquids, in particular for beer or carbonated beverages, characterized in that it is constituted by two mutually opposite and integral pistons sliding inside two cylinders which generate, with their reciprocating motion, four variable-volume chambers inside two of which the fluid, through suitable valves, is alternatively intaken and delivered by a gas whose pressure is modulated by a suitable pressure regulator, in which it is the pressure of the same delivered liquid to counteract the calibration force, with said gas alternatively going to act, by means of suitable control means, inside the chamber behind the delivery chamber, so that the delivery pressure of the same liquid remains constant and predetermined, wherein said delivery pressure is obtained as the sum of the thrust of the liquid intaken from the opposite chamber, plus the modulated gas pressure, which acts on the rear face of the delivery piston.

Patent No. 2792692A: Keg Cooler And Dispensing Bar Unit

patent-logo
Today in 1957, US Patent 2792692 A was issued, an invention of Reed A. Bryan, for his “Keg Cooler And Dispensing Bar Unit.” There’s no Abstract, though it’s described this way in the application:

The primary object of the invention is to provide a combined keg cooling enclosure simulating a large beer barrel, dispensing bar and faucet, and auxiliary pressurizing equipment in a single unit for use at picnics, beach and boat parties, club outings and the like events.

More specifically, it is intended now to provide a keg enclosure in the form of a relatively large open-top barre]. A bar-top removably fitted over the top of the barrel so that a keg may be set down within the barrel and packed with ice, and tapping and dispensing equipment including a faucet mounted on the bar-top and a carbon dioxide cylinder mounted exteriorly of the barrel with gas connections to the top. By this arrangement there is to be provided a complete unit which may be set up iced by a distributor or dealer and delivered to the consumers in readiness for tapping and utilization without further ado.

Patent No. 4665940A: Container Fitting

patent-logo
Today in 1987, US Patent 4665940 A was issued, an invention of Charles S. Jacobson, for his “Container Fitting.” Here’s the Abstract:

A fitting for a container of draft beer or the like includes a first valve for permitting pressurized gas to be injected into the container and a second valve for permitting beer to be dispensed from the container. Both valves are urged to their closed positions by inexpensive elastomeric springs which also serve to hold certain components of the fitting in assembled relation. A coupler attaches the fitting to the container and enables the container to be used with Sankey-type taps.

Patent No. 3251386A: Filler Valve Assembly

patent-logo
Today in 1966, US Patent 3251386 A was issued, an invention of Frank A. Bellato, for his “Filler Valve Assembly.” There’s no Abstract, but in the description it states that the “invention relates to container filling apparatus, and particularly to what is known as a racker assembly used to fill beer kegs and the like.” But it’s primarily this.

The major object of the invention is to provide a racker assembly by means of whicha beer keg may be quickly and easily filled with a free unobstructed flow, while at the same time a supply of a gas under pressure (such as CO is being introduced into the keg to minimize turbulence and foaming of the beer as delivered into the keg.

Patent No. 2001040A: Beer Dispensing Equipment

patent-logo
Today in 1935, US Patent 2001040 A was issued, an invention of David Sweeney, for his “Beer Dispensing Equipment.” There’s no Abstract, but it’s described as an “invention relat[ing] to beer dispensing equipment, and more particularly to equipment for handling, cooling, and dispensing, beer or other liquids.” And this appears to be the main feature.

One feature of my invention is that it is adapted for easy handling of quantities of liquid up to ten gallons or more. Another feature of my invention is the provision of means for expelling liquid, for example, beer, from a container without exposing the liquid remaining in the container to air. This is especially useful in dispensing beer where one container may be more or less infrequently used. In the ordinary case, for example, if a beer container is partially emptied, and air allowed to enter the container to fill up the space previously occupied by the liquid drawn off, the liquid remaining in the container is likely to become spoiled by contact with the air, especially if not used rather promptly. All these objections are overcome by my inventions I apply an inert gas, for example, carbon dioxide gas, (or some gas which will not spoil the beer or other liquid in the container) to the top of the container under suitable pressure. This gas then serves not only to expel the liquid from the container as it is used, but also fills up the space in the container occupied by the liquid drawn off, so that no spoilage results to the liquid remaining in the container. Still another feature of my invention is the elimination of cooling coils with their tendency to spoil beer standing in them.
