Today in 1958, US Patent 2842293 A was issued, an invention of Robert S. Knapp and Richard B. Nebinger, for their “Dispensing Apparatus.” There’s no Abstract, although in the description it includes this summary:

The present invention relates generally to a dispensing device, and more particularly to an apparatus for pressurizing a liquid container and regulating eduction flow therefrom.

The sale of beer and similar ebullient liquids in relatively large containers, particularly gallon size, for home use necessitates the provision of a simple, efficient and reliable dispensing means for providing a constant pressure on the beer within the container and for regulating eduction flow therefrom. It is desirable to provide dispensing means of this type wherein carbon dioxide pressurization by means of a sparklet bulb may be employed. Several difficult problems arise, however, in attempting to adapt an efficiently operating apparatus to the use of sparklet bulb pressurization. In particular, it is necessary to maintain a constant pressure on the beer throughout the dispensing life of the container, so that the last volume of beer Withdrawn will be received at substantially the same flow rate and pressure as the first volume. It is of further importance to prevent foaming of the beer as a result of agitating and mixing by the pressurizing gas. In addition, the use of carbon dioxide as the pressurizing gas also presents the problem of parts freezing within the bulb mechanism.

it is a primary object of this invention, therefore, to provide a dispensing device of the type described having novel pressure regulator means for providing a constant dispensing pressure.

It is another object to provide a dispensing device of the type described, wherein the pressurizing gas is released above the top. surface of the liquid Within the container in a manner which eliminates the possibility of agitation and consequent foaming of the liquid.

It is a further object to provide a dispensing device of the carbon dioxide type having novel means for preventing freezing within the carbon dioxide release mechanism.

It is still another object to provide a dispensing device of the type described having a self-closing, manually actuated push button type of valve for regulating dispensing flow through a spigot.

It is still a further object to provide a dispensing device of the type described having safety relief valve means to prevent excessive internal container pressure in the event of accidental malfunction of the pressure regulating or dispensing valve means.

Today in 1937, US Patent 2085848 A was issued, an invention of Richard T. Cornelius, for his “Beer Dispensing Device.” There’s no Abstract, although in the description it includes this summary:

My invention relates to beer dispensing devices and has for an object to provide a device by means of which beer may be drawn in a manner to procure the desired amount of foam or collar on the beer when discharged into any type of drinking vessel.

Another object of the invention resides in providing a device in which the amount of foam produced can be varied.

An object of the invention resides in providing a dispensing device including a flow regulating device and a faucet and in which the rate of flow can be adjusted independently of the operation of the faucet.

Today in 1899, US Patent 628084 A was issued, an invention of John D. Freese, for his “Beer Dispensing and Pipe Cleaning Apparatus.” There’s no Abstract, although in the description it includes this summary:

The main object of my invention is to provide convenient means for cleaning the pipes in a beer dispensing system so arranged that an operator may clean the pipes by turning on the water at the dispensing end, the water passing into the beer-pipe near the storage end and thence discharging through the beer faucet.

Today in 1934, US Patent 1964836 A was issued, an invention of Abram W. Wheaton, for his beer “Faucet.” There’s no Abstract, although in the description it includes this summary:

This invention relates, generally, to faucets and the invention has reference, more particularly, to an improved faucet, which while adapted for general purposes, is especially intended for use as a beer faucet.

The principal object of the present invention is to provide an improved faucet having a novel construction of gas separating bafile incorporated therein, said bafile serving to liberate a considerable portion of the carbon dioxide and other gas content of the beer as the same flows through the faucet, thereby greatly reducing the amount of foam ordinarily produced when drawing beer and preventing considerable waste which usually occurs when using ordinary beer faucets.

Another object of the present invention lies in the provision of an improved faucet having a novel sheet metal gas separating baffle of simple, rugged construction, the said baflle being so constructed as to enable the same to be readily inserted into or removed from the faucet and having means to insure its proper installation in the faucet.

Today in 1935, US Patent 2006940 A was issued, an invention of Henry H. Brockmeyer, for his “Bung and a Method of Making Bungs.” There’s no Abstract, although in the description it includes this summary:

The invention relates to means particularly adapted to prevent seepage of liquids through bung and in many instances, especially for the reason that presently bungs usually are constructed from wood derived from relatively small trees, the grain does not extend parallel with the inner and outer surfaces of the bung but curves inwardly or outwardly whereby the liquid, particularly beer, which is under relatively heavy pressure within the container, is adapted to seep through the pores in the wood of the bung, or through the channels adjacent the grain. Moreover, the pressure of air or gases within the container is reduced as by escape of such air or gases through the pores or channels, in the bung, adjacent the grain, simultaneously when the liquid within the container seeps therethrough. Since it is advantageous to retain the air or gas pressure within the container, as well as prevent seepage of the liquid from within said container outwardly through the bung, any leakage of air or seepage of liquid is undesirable.

Therefore, an important object of the invention is to provide simple, efficient, practical and economical means to prevent passage of air or gases through a bung and to prevent seepage of liquid through said bung.

Other objects of the invention are to provide dependable means adapted to render the inner surface of a bung impervious to liquids, such as beer, whiskey, and the like; and to provide means which is unlikely to interfere or retard natural expansion of said bung, when contacted by said liquid, for the purpose of sealing the bung hole in which said bung is positioned.
