Today in 2010, US Patent 7757908 B1 was issued, an invention of Thomas R. Buhl, Jr., for his “Portable Container and Dispenser For Kegged Beer.” Here’s the Abstract:

A combination beer container and dispenser includes an outer container having a top section provided with an opening centrally formed therein. The top section includes a removable lid selectively positional in the opening. The outer container further has front and rear sections and includes a plurality of flange portions extending inwardly and orthogonally from the front and rear sections. An inner container having a cylindrical shape defines a cavity therein. A mechanism for dispensing beer from the keg and a mechanism for securing the keg within the inner container are also included. An axle having opposed end portions is positioned in a bore. A drain cock is directly conjoined to the rear and is manually adaptable between open and closed positions. A plurality of wheels are conjoined to the end portions of the axle. Such wheels include coextensive and juxtaposed ridges for providing traction.

So I’m not sure what to make of these. For nearly two years, I’ve been searching through Google’s patent search and blogging beer-related patents as I find them. And there are a lot of them: some historic, some by people I know (or knew), some surprising and some truly weird ones. Today, I found two separate patents, from two different years — 1948 and 1965 — but both issued on the same day — July 20 — and both of them assigned to the Firestone Tire & Rubber Co. even though each one of them is beer-related — kegs, really — and as far as I know, they had nothing to do with beer during those time periods. So let’s go through each of them.

Patent No. 2445730A: Reinforced Sectional Barrel

Today in 1948, US Patent 2445730 A was issued, an invention of Max O. Kuhn, assigned to the Firestone Tire & Rubber Co., for his “Reinforced Sectional Barrel.” There’s no Abstract, although in the description it includes these claims:

This application relates to containers, and more especially to single walled metallic containers.

An object of the invention is to provide an improved container comprising corrosive and noncorrosive metal, said corrosive metal being protected not only from liquid contents within the barrel, but also from direct contact with the atmosphere.

Patent No. 3195760A: Single Walled Double Compartment Container

Today in 1965, US Patent 3195760 A was issued, an invention of William Bulgrin Walter, assigned to the Firestone Tire & Rubber Co., for his ” Single Walled Double Compartment Container.” There’s no Abstract, although in the description it includes these claims:

The present invention relates to containers and in particular to single walled metal beer containers with double compartments.

When beer is initially placed in containers for subsequent dispensing it contains a certain amount of natural carbon dioxide gas which serves to maintain the condition of the beer and keep the flavor lively so long as the container remains sealed. When the container is tapped and as the beer is withdrawn the evacuated space must be filled with a pressure balancing medium of some kind.

If the evacuated space is permitted to be filled with impure air any microorganisms carried in this air will tend to contaminate and impair the flavor of the beer and shorten considerably the useful life of the beer. Also unless the replacement medium enters the container quickly, enough of the natural carbon dioxide gas will be thrown off by the beer itself to fill this evacuated space thus causing a loss of condition of the beer and resulting in a flat taste.

In order to dispense the beer from the container it is necessary to use certain auxiliary equipment, such as pumps, valves and possibly long or involved piping, which equipment often may be a common source of contamination.

To avoid permitting impure air from entering and filling the evacuated space as the beer is Withdrawn, it is often considered preferable to use a separate source of carbon dioxide which involves a certain amount of additional equipment such as the gas cylinders themselves in order to dispense the beer under pressure. The use of carbon dioxide gas would be preferable to pump systems requiring facilities for sterilizing the air which is permitted to enter the evacuated space. A further reason for the use of carbon dioxide is that it serves to prevent the natural carbon dioxide in the beer itself from being thrown off inside the container, thereby ensuring that the flavor is kept lively for a longer period of time.

Accordingly, one of the objects of the invention is to provide a single walled metal container having a separate compartment for the storage of carbon dioxide gas.

Another object of the invention is to provide a single walled metal container having double compartments, one for the storage of a suitable gas and the other for the storage of a beverage, the container being readily adaptable for establishing communication between the two compartments when tapped through a conventional and simple equipment.

It is still another object of the invention to provide a method of fabricating single walled double compartment metal containers of various dual volume capacities from a single standard size container type.

I know that Japan’s Bridgestone Tires bought Firestone Tires in 1988, but I’m unclear as to when the Firestone family was no longer in control, or had sold the business. This is at least 32 years before Adam Firestone and David Walker started the Firestone Walker Brewing Co., and even for the more recent patent, Adam would have been just a kid. So why would Firestone Tires be patenting kegs, or improvements to kegs? Rubber seals, perhaps? Or just some weird quirk of business, who knows?

Today in 1965, US Patent 3195779 A was issued, an invention of William J. Ruff, for his “Beverage Dispenser.” There’s no Abstract, although in the description it includes these claims:

This invention relates to a beverage dispenser which is particularly useful for dispensing beer and other carbonated beverages.

One object of the present invention is to provide a new and improved device for dispensing carbonated beverages from cans or similar containers of relatively small capacity, such as one gallon, for example.

Another object is to provide a new and improved beverage dispenser in which the beverage is supplied in cans having openings which are sealed initially with closure plugs made of rubber or rubberlike material.

A further object is to provide a beverage dispenser in which the beverage to be dispensed is withdrawn from the cans by means of tapping pipes which are adapted to penetrate the rubber plugs mounted in the openings in the cans.

A further object is to provide a beverage dispenser in which each can is provided with two openings closed with rubber plugs, one plug being adapted to receive a tapping pipe for withdrawing the beverage while the other plug is adapted to receive a tapping pipe through which carbon dioxide (CO) under pressure is introduced into the can to provide pressure for dispensing the beverage.

Another object is to provide new and improved beverage cans having rubber closure plugs, each of which is formed with an imperforate diaphragm, together with means forming a recess for receiving the remnant of the diaphragm after the diaphragm has been punctured by a tapping pipe. It is a further object to provide a new and improved rubber or rubberlike closure plug of the foregoing character which is constructed and arranged to prevent any leakage between the tapping pipe and the plug, and also to prevent the tapping pipe from being pushed outwardly through the plug by the force produced by the CO pressure in the can.

A further object is to provide such a new and improved rubber plug which is formed with a lower sleeve portion having a bore therein which is initially of a substantially smaller diameter than the tapping pipe, so that the sleeve portion will be stretched substantially by the insertion of the tapping pipe, the sleeve portion being adapted to grip the tapping pipe tightly, due to the stretching of the sleeve and also due to the pressure of the CO on the sleeve.

Another object is to provide a new and improved beverage dispenser adapted to dispense carbonated beverages from sealed can of small size so that the dispensed beverage will always be fresh and will be prevented from going hat or stale.
