Historical Beer Birthday: John Lofting

beer-engine
Today is as good a day as any to celebrate the birthday of John Lofting (1659–June 15, 1742). Like many people born centuries ago who weren’t royal or otherwise well-born, we don’t know the exact day he was born, but we do know that he died today. Lofting was a Dutchman who lived in London as an adult, and patented several devices, the most famous of which was the fire engine, but he may also have been responsible for the beer engine.

John-Lofting

Here’s his Wikipedia entry:

Originally Jan Loftingh, John Lofting was an engineer and entrepreneur from the Netherlands. His parents were Herman and Johanna. He moved to London, England, before 1686. He patented two inventions being the “sucking worm engine” (a fire engine) and a horse-powered thimble knurling machine. His mill was set up in Islington, where Lofting Road is named after him. However, in or about 1700, he moved his main operation to Great Marlow in Buckinghamshire to take advantage of the River Thames’ ability to turn a water wheel which improved productivity, enabling the production of over 2 million thimbles per year.

And while Joseph Bramah patented the first practical beer engine, Lofting’s design made it possible for Bramah to build on and create his. Although there’s little I could find specific about Lofting’s invention, it is mentioned in the Wikipedia entry for the beer engine:

A beer engine is a device for pumping beer from a cask in a pub’s cellar.

The beer engine was invented by John Lofting, a Dutch inventor, merchant and manufacturer who moved from Amsterdam to London in about 1688 and patented a number of inventions including a fire hose and engine for extinguishing fires and a thimble knurling machine as well as a device for pumping beer. The London Gazette of 17 March 1691 stated “the patentee hath also projected a very useful engine for starting of beers and other liquors which will deliver from 20 to 30 barrels an hour which are completely fixed with brass joints and screws at reasonable rates.”

The locksmith and hydraulic engineer Joseph Bramah developed beer pumping further in 1797.

The beer engine is normally manually operated, although electrically powered and gas powered pumps are occasionally used; when manually powered, the term handpump is often used to refer to both the pump and the associated handle.

The beer engine is normally located below the bar with the visible handle being used to draw the beer through a flexible tube to the spout, below which the glass is placed. Modern hand pumps may clamp onto the edge of the bar or be mounted on the top of the bar.

A pump clip is usually attached to the handle by a spring clip giving the name and sometimes the brewery, beer type and alcoholic strength of the beer being served through that handpump.

The handle of a handpump is often used as a symbol of cask ale. Keg beer dispensers usually feature illuminated countertop fittings behind which a handle opens a valve that allows the gas pressure in the keg to force beer to the attached spout.

Historic Beer Birthday: Joseph Bramah

handpump
Today is the birthday of Joseph Bramah (April 13, 1748-December 9, 1814). Bramah was an English engineer, and inventor, whose most famous invention was the hydraulic press. But he also made improvements and created a practical beer engine, creating his beer pump and engine inventions between 1785 and 1797.

Joseph Bramah- portrait in oils

Another summary of his achievements is quite flattering:

English engineer and inventor whose lock manufacturing shop was the cradle of the British machine-tool industry. Central in early Victorian lockmaking and manufacturing, he influenced almost every mechanical trade of the time. Like Henry Ford, his influence was probably greater for the manufacturing processes he developed, than the product itself. He took out his first patent on a safety lock (1784) and in 1795 he patented his hydraulic press, known as the Bramah press, used for heavy forging. He devised a numerical printing machine for bank notes and was one of the first to suggest the practicability of screw propellers and of hydraulic transmission. He invented milling and planing machines and other machine tools, a beer-engine (1797), and a water-closet.

As for the actual patents, there were two of them. The first was in 1785 and was for what he called a “beer pump.” Then, in 1793 he was granted Patent No. 2196 for his improved version, now referred to as a “beer engine.” It was actually a Dutchman, John Lofting, who had first invented the beer pump in 1688, but Bramah’s were more refined and practical, and more importantly, patented. Curiously, Grace’s Guide to British Industrial History lists the patent dates as 1787 and 1797, so it’s unclear which are the correct dates.

In this engraving, entitled Men of Science Living in 1807-8, Bramah is on the left side, the tenth one in the back from the left. He’s the one with the wide sash across his chest and the star-shaped badge on his jacket. Others include Joseph Banks, Henry Cavendish and James Watt.

There’s even a J.D. Wetherspoon’s pub in his home town of Bramley called The Joseph Bramah

Patent No. 517400A: Pitching Casks

patent-logo
Today in 1894, US Patent 517400 A was issued, an invention of Louis Wagner, for his “Pitching Casks.” There’s no Abstract, although in the description it includes this summary:

It is the object of my present invention to provide for heating the interior of casks, such as those used for the storage and transportation of beer, for the purpose either of applying new pitch to the same or for the purpose of melting and removing the old and impure pitch to allow of the reapplication of a fresh coating. By my improvements I provide for heating the casks interiorly in a rapid, thorough and economical manner, and at the same time enable the heat so applied to be accurately tempered in order that the heat and fuel may not be wasted or the interior of the cask or the pitch, injured. For this purpose I combine with a suitable heating chamber analogous in construction to a steam boiler and having an air inlet, a steam injecting apparatus adapted to force into the heating chamber such amount of air as will together with the steam when highly superheated produce the volume of vapor necessary for heating the cask. The steam jet forms the motive power for passing the vapor to be heated through the heating chamber and for applying it interiorly to the cask, and at the same time serves by the regulation of its amount to accurately determine the temperature of the vapor at the point where it performs its heating function. I further provide a stand of improved character to receive the Cask or keg while it is being operated upon.
