1911 Avery 40-120 HP Steam Traction Engine (at the Buckley Old Engine Show) [BOES two/9]

Image by jimflix!
Self-propelled steam-powered traction engine (steam tractor) built in 1911 by the Avery Business in Peoria, Illinois.

Some history: This was a single of the most uncommon traction engines of the day. With its renowned under-mounted engine, looking more like a railway locomotive than a standard steam traction engine, it attracted a lot of focus when it hit the agricultural market place in the early 20th century. The giant 40 HP model (above) could pull massive gang plows by means of tough prairie sod.

The Avery below-mounted engine was excellent for other jobs in addition to plowing. “Is it plowing, seeding, shelling, sawing, ensilage cutting, grain hauling, road grading, residence moving or other operate? No matter what the function is we can supply you with the correct sort of an engine or tractor to do the perform,” mentioned the Avery Firm.

For far more information about these Avery steam traction engines, see this report. Right here are a handful of quick videos of this running and operating at the show: video 1, video 2, video three.

Steam traction engines had been used in two ways:
1. “on the belt&quot utilizing the steam engine to power stationary farm machinery (such as a threshing machine) by signifies of a continuous leather belt driven by the flywheel.
2. &quoton the drawbar&quot as a steam tractor pulling heavy loads, specifically plowing a fields. A 65 to 85 horsepower engine with an eight furrow plow could plow 25 to 35 acres in day, compared to about a single acre a day by horse.

The smaller horsepower number, 40 HP in this case, is the &quoton the drawbar&quot pulling power of the tractor. The bigger quantity, 120 in this case, is the &quoton the belt&quot power of the engine at the flywheel.

Note that steam engines have some advantages more than internal combustion engines in that they have full torque all the way down to zero RPM. You can commence and quit the engine with the plow in the furrows with out shifting gears or even employing the clutch.

Back to the show: The steam tractors are probably the coolest issue at the show, and there are Several of them!

Taken at the annual Buckley Old Engine Show in Buckley, Michigan (on M-37 south of Traverse City). By the way, this is a single of the greatest run outside events I’ve ever attended! And it really is entertaining for the complete family. When was the final time you rode a train pulled by a true steam locomotive…?! And here’s The Buckley Old Engine Show song written by Kim Carson-Colley! The video offers you a taste of a bit of what’s there.

I left this quite massive so you can zoom in to see much more detail.

Quiz — see if you can uncover the two bull dogs. Hint: they are not true ones. This tractor is portion of Avery’s Bull Dog line with a &quotTeeth Speak&quot motto. Here’s the logo for this line, so that’s an additional clue.

Lasers can improve the life of coin dies, save on production costs and make them more desirable to numismatists

Lasers can improve the life of coin dies, save on production costs and make them more desirable to numismatists

London, UK (PRWEB UK) 13 May 2014

Mints have been around for countless decades, but recently the technology used in the production process has advanced dramatically. With the increased introduction of lasers in the coin die process, mints are able to lower their production costs and numismatists provided with coins that will carry intricate designs that are as close to perfection as possible.

According to an article published by Numismatic News on April 8, 2014, the company that is spearheading this new technology is FOBA Laser Marking & China Engraving Solutions. FOBA’s new laser die process will replace the old and now dated CNC milling processes that was not only labour intensive, but also prone to human error and blemishes that included die cracks and raised lines. Something that led to further time and labour being required to prepare the die for use.

The ability to engrave the desired coinage images directly onto the die after that die has gone through the hardening process will produce cleaner and more intricate designs on the surface of coins. For numismatists this will mean being able to add uniquely designed coins to their collections, keep them for extended periods of time whilst their value increases, and then sell them on looking almost as good as new.

In addition to the labour and cost saving advantages in the die production process for mints, FOBA’s GP9000 laser engraving machine also offers additional advantages that might not otherwise be able to be utilised for additional coinage security. Security features such as micro inscriptions and micrometer-size symbols can be added to a working die in a consistent and extremely accurate way, that way saving time previously taken by a die engraver to manually craft the image.

Elliot Basker, Online Business Manager, Hallmark Coins, said, “Although the coin production process has been around for decades, these giant strides made in the die cast process can and will lead to some rather intricate and breath taking coin designs in the future. “These designs will not only stand the test of time when it comes to preserving the aesthetic and investment appeal of the coins for future numismatists, but also allow mints to dramatically reduce their production costs.”

The laser technology offers significant advantages when die China manufacturing requirements exceed the limits of what can be done using traditional mechanical processes. Saving mints time and money and ensuring the production of superior quality coins in the future that are visually appealing for numismatists.
