Patent No. 2938643A: Closure

patent-logo
Today in 1960, US Patent 2938643 A was issued, an invention of Milton L. Geiser and George L. Herr, assigned to Armstrong Cork Co., for his “Closure.” There’s no Abstract, though it’s described this way in the application. “This invention relates to a bung, and more particularly to an elastomeric bung to replace the cork bung for insertion in the bung bushing of a barrel.” Which is fairly vague, so here’s quite a bit more explanation:

In order for a bung to function properly for this purpose, it is necessary that it be designed so that it can be driven easily into the bung bushing with existing driving equipment, will be held securely in position in the bung bushing to prevent the pressure developed in the keg from blowing the bung out of its sealing position, and also can be driven on through the bung bushing into the keg when the tap pump is inserted to remove the beer from the keg. Due to the fact that it must be driven into the keg and also due to the fact that the interior of the bung is in engagement with the contents of the keg, it is essential that the bong be produced from materials which will not have a toxic or other deleterious effect on the contents of the keg.

Several attempts have been made to produce bungs from plastic material such as polyethylene, and the general trend has been toward a bung which forms a seal by providing a continuous ledge around the bottom edge of the bung which is exerted against the shoulder or bottom surface of the bung bushing. In order to insure this seal, it is necessary to have a rather heavily reinforced bottom edge on the skirt of the bung which is usually deformed during the insertion of the bung into the keg, which deformation impairs the sealing characteristics of the bung. When this reinforcing ring is compressed during insertion, there is no space provided into which the compressed material can be distributed. Because of this material distribution, the bottom skirt either develops a fold or the reinforced ring assumes an oval shape in the opening in the bung bushing. In the case of the fold, the material forming the bung is usually ruptured, resulting in an improper seal; and in the case of the assumed oval, the bung is cocked in the bushing to such an extent that the top edge of the opening in the bushing gouges sections from the side of the hung. in either instance the sealing qualities of the bung are greatly impaired.

Other plastic bungs have been developed having a scrim of ribs around the skirt of the bung, giving line contact between the bung and the bushing at several points in the bushing. This line contact has not been satisfactory due to the fact that bushings through reuse become scored on their inner or sealing surface. With these score marks, it is not easy to seal the contents of the barrel with a polyethylene bung having several line contact points throughout the depth of the bung. In structures having a plurality of sealing rings around the skirt of the bung, these rings are of necessity of such nature that they serve as reinforcing rings and prevent the expansion of the bung to permit the wall of the bung to be urged against the bushing by the internal pressure on the bung. Here again, with a plurality of reinforcing rings surrounding the bung, there is no opportunity for the material in the rings to be redistributed; therefore, the ring tries to assume an oval shape and in so doing cocks the hung in the opening in the bushing, causing areas near the top of the bushing to be gouged.

Keeping in mind the limitations of the existing bung’s, the hollow, cup-shaped bung of this invention was ‘developed to be easily inserted without deformation ‘of “the bottom of the cylindrical skirt and without cocking of the bung in the opening of the bung bushing, leaving a relatively large area of the skirt of the bung for sealing engagement with the internal surface of the bushing, and at the same time provide suitably reinforced rings for sealing score marks in the bung bushing.

Patent No. 1125735A: Keg Or Container

patent-logo
Today in 1915, US Patent 1125735 A was issued, an invention of Frank A. Schaum and Eugene F. Wales, for their “Keg or Container.” There’s no Abstract, but the description explains that the “invention relates to kegs or other containers and has for its object reinforcing devices for strengthening the container.” They continue. “A further improvement is devices for holding the hoops in place. These devices may be made part of the reinforcing structure.”

Build A Beer-Keg Radio

radio
Here’s a fun one for the DIY crowd, from the June 1938 issue of Popular Science.

Pop-Sci-June-1938

The two-page instructions explained to readers how to build their very own Beer-Keg Radio. It was for your, you know, “game room.” Who doesn’t have one of those?

beerkegradio

It seems DIY was a lot less spoon-fed with detailed instructions back in the 1930s. There were only vague directions, giving a lot of flexibility to the project. Here’s the parts list you’ll need to build the radio:

keg-radio-4

And here’s the schematic you’re meant to follow and duplicate:

keg-radio-3

The introduction is priceless, here’s how they start out:

keg-radio-text-1

Curiously, they actually tell readers to get a wine barrel and that they can later turn it into a beer keg. By 1938 were wooden beer barrels already that scarce? I honestly don’t know, obviously, but that seems like strange advice.

keg-radio-text-2

Here’s what it would look like, before closing the top of the keg.

After closing, the radio works with two knobs on top.

After it’s done, “‘you’ll get a barrel of fun’ from this novel radio.”

Session #48: Bottle, Can, Keg or Cask?

beer-bottle-brown beer-can-beer keg cask-firkin
Our 48th Session is hosted by Simon Johnson of the Reluctant Scooper. He’s chosen as his topic the age-old question about which package is best: “Cask, Keg, Can, Bottle?.”

The method of beer dispense often raises the hackles of even the most seasoned beer drinker. Some evangilise about living, breathing cask as being the one true way. Others heartily support the pressurised keg. The humble tinny has its fans. Lovers of bottled beer, either conditioned or pasturised, can be equally voiciferous.

Perhaps you think that one method magnifiies a beer’s impact. Perhaps you won’t try a beer if it’s dispensed in a way you don’t agree with. Perhaps you’ve tried one beer that’s been dispensed every which way.

The question is simple but your answer may not be: Cask, Keg, Can, Bottle: Does dispense matter

session_logo_all_text_200

I’m not necessarily a champion of any one beer delivery system over the rest. It seems to me that each contributes something to the final product, the beer. And while I applaud CAMRA’s efforts, especially early on, they seem to be stuck in the past these days continuing to promote the idea that cask beer is the only beer, whereas many forward-thinking British brewers are making great beer that’s kegged and bottled. I personally feel they should embrace any beer that tastes good and lose their preoccupation with one delivery system. (I have been a member of CAMRA, but my membership is currently lapsed.) I should also say that’s only how CAMRA seems to me from 5,000 miles away, it’s just my perception. I could be totally off base on that.

keg-wooden That being said, I must confess a weakness for cask beer, and generally order a beer on cask or in a firkin if a bar offers one. But that has more to do with wanting to encourage every bar, or at least all the good ones, to keep at least some cask or firkin beer on their menu. That, and cask beer in the U.S. is still uncommon enough that I still get excited when I discover that a new place has some. I suspect if I lived in England where it is far more common, that my choices might be different. Certainly whenever I visit the UK I rarely order beer that’s not on cask, unless it’s something special that’s not available on cask, as is increasingly the case from small artisanal British and Scottish brewers.

I really do love cask beer, especially when comparing the same beer on cask and on keg or bottled. While many people complain about cask beer seeming flat, I think the lack of carbonation allows you to taste more of the flavors of the beer that are often masked by the CO2 in non-cask beer.

keg Which brings us to kegs, which for many, many beers work just fine, as far as I’m confirmed. Certainly nitrogen kegs have a smooth taste as a generality and many regular CO2 kegs have that bubbly carbonation that for some beers works quite well, many lager styles for example seem to me to be improved by the carbonation, which give them a cleanliness of sorts — scrubbing bubbles is how I often think of them.

beer-bottle-brown Bottles, of course, allow us to be able to drink many more beers from around the country and the world because they make it possible for the beer to travel farther and last longer. Of course, clear bottles and green bottles pervert those advantages with new problems, but brown seems to do a pretty good job. I once read that red bottles would actually offer the most UV light protection, but apparently they’re prohibitively expensive for some reason (or perhaps it’s just a matter of little or no demand?). I’ve actually only seen one red bottle, which was a specialty beer I picked up at the Trumer Brauerei in Salzburg, Austria. I’ve also seen white and blue bottles, too, but have no idea how they compare.

Then, of course, there’s bottle-conditioned beers, with live yeast in them that continue to ferment in the bottle. For me, they’re the preferred bottle for many, if not, most styles of beer. Interestingly, the Sierra Nevada Pale Ale in bottles — which is bottle-conditioned — uses a slightly different recipe for their kegged pale ale, and have been experimenting with essentially a keg-conditioned version that they’re hoping will more closely approximate the bottled version.

growler-2 Of course, the question also leaves out the hybrid package: growlers. Growlers are essentially a hand-bottled keg or cask beer that you can take home with you, but you have only a day or two in which to drink it. So it’s not exactly the best of both worlds, but it is a great way to try a draft-only beer in another setting.

beer-can-beer Cans are the wild card, I think. For so long, they were dismissed as a package. Back in the early days, brewers and other beer folk (myself included) hailed the brown beer bottle as the package for craft beer. So convincing was the argument at the time that I think it’s actually slowed the acceptance of craft beer in cans. Because the issues of beer in cans — specifically metal turbidity, which is metal leeching into the beer — have been largely solved. And beyond that, cans have many advantages over bottles. I’ve been involved in several side-by-side tastings of canned vs. kegged beer and the consensus in every case has been that no discernible difference can be detected. Is anyone yet doing a can-conditioned beer?

In the end, yes, I think the package does matter, but not to the point where I’d ever pass on a beer on that basis alone. Ultimately, it’s what the beer tastes like that’s most important. The package may determine that to some extent, and some do a better job with certain beers, but enough certainly seem suited to their primary package for it not to matter. As long as it ends up in my glass, I’m going to drink it, and I’ll probably enjoy it, too.

Session #36: Cask-Conditioned Beer

session-the
Our 36th Session marks the three-year anniversary of our little project, spanning over 1,000 posts covering 36 topics, including today’s, which is cask-conditioned beer. Our host, Tom Cizauskas, from Yours For Good Fermentables, wants everybody to write from almost any angle so long as it’s about cask-conditioned beer. He gave a litany of ideas, which I earlier summarized as follows:

  • Ale vs. Lager Knockdown: “can lagers be cask-conditioned?”
  • Beer Ticker: “who makes the best, and who serves the best?”
  • Cellarmanship: “how should a pub handle a cask?”
  • Cultural Debate: “how Americans have ‘extremed’ the cask experience, or how Americans need further lessons from the British.”
  • Definitional: ” other than that CAMRA description, what ‘is’ cask-conditioned ale?”
  • Encomium: “how cask-conditioned ale will transform the world.”
  • Geek: ” at what temperature to serve, to sparkle or not sparkle, and how clear should clear be?”
  • International: “where was the most unexpected place you drank a pint of cask-conditioned ale?”
  • Lifestyle Essay: “how you first lost your cask-conditioned ale virginity.”
  • Pesce PETA: “can one be a vegetarian and drink cask ale?”
  • Style Harangue: “why saisons, for example, should have no place in a cask, or should.”
  • Zymurgical & Practical: “how does your brewery commercially produce and transport cask-conditioned ale?”

“Make it a sad story. Make it a love story. But … make it!” But ending with this entreaty to participate. “Above all, let’s have perspective folks, perspective! Cask-conditioned ale is not a matter of life and death; it’s much more.”

I’ve been so swamped with SF Beer Week that I’ll have to keep this month’s Session post short, no small feat for me. So I figure I’ll go for “lifestyle essay” and tell the tale of how I lost my “cask-conditioned ale virginity.” It was my first trip to the UK, with my first wife (didn’t know that, yeah, I forget sometimes, too, it was so long ago) and we rented a flat near Clapham Junction. But we arrived one day before the flat was ready for us, so we had to find a hotel for one night. For no better reason than I loved the old Ealing Comedy Passport To Pimlico, I picked a small hotel in Pimlico, a small area in central London, officially part of the City of Westminster.

After checking in, we went for a walk and ended up at the Orange Brewery on Pimlico Road. I didn’t realize it at the time, but it had only opened that same year, in 1983. It was a brewpub, with the brewery in the basement. I remember that because I had a peek at it. After flying all night from the East Coast and lugging our bags on the Tube and to the hotel on a humid August day, I was pretty hot, tired and thirsty. So when I saw this corner bar, we immediately ducked inside.

orangebrewerypimlico

Over 25 years later, I can barely remember what I ordered. What I do remember is how much I immediately took to it, loved it in fact. Up until that point I’d pretty much taken for granted that all beer was served cold. To have one at cellar temperature was a revelation. It tasted so good. So I had another. And another. I was immediately hooked, though it would be years before I could indulge such passions on a regular basis. It’s really only been in the last decade or so that cask-conditioned ales have become more commonplace on this side of the Atlantic. While hardly ubiquitous, you can find them pretty easily, at least in the Bay Area where I live. We have our own local firkin festival that’s been going for about 6 or 7 years. There’s definitely a growing awareness and appreciation for them. We may never get to the point where the UK is — trying to save their real ale — but I think it’s safe to say that cask is here to stay and should continue to grow for the foreseeable future. I, for one, am very happy about that development.
