Показать описание
Here is a 1917, 600 Horsepower Snow gas compressing engine running at the Coolspring Engine and Tractor show. This engine was manufactured by the Snow-Holly Works in Buffalo, NY. The rated output of the engine is 600 HP at 100 RPM, which yields a torque value of 31,500 ft-lbf. The natural gas compressing cylinder at the front of the engine was also manufactured by Snow and features an 18 inch bore and a 48 inch stroke. The compressor accepted gas at approximately 50 psi and raised it to 450 psi. Upon peak compression, the gas in the cylinder exerted a force of about 114,300 pounds on the piston. The engine is 75 feet long with a 18 ton, 18 ft diameter flywheel. The overall weight of the engine is estimated to be about 140 tons! The engine was owned and operated by National Fuel Gas Corporation of Titusville, PA and was donated in 1992.

I love how these old engines each have their own distinct rhythm. It's mesmerizing.

It's impressive seeing that much steel moving at that speed. The amount of momentum there is incredible.

It's amazing how that little brass arm can push that big piston back and forth so quickly.

People wonder why I admire and like old stuff a lot more. Stuff like this engine. Made over 100 years ago and look at it. The craftsmanship is amazing.

Great to see an old engine being ran at its proper speed and also not powered by compressed air. The changes in direction of the connected mass is incredible. The forces behind that movement must be impressive.

And to think that was machined and assembled in the days long before CNC and Laser Alignment. Beautiful.

Man, this thing was playing a tune. Very cool piece of engineering.

I have so much respect for Worthington devices. As a young man very long ago, it was my job to start the 3 big Worthington air compressors for the entire multi building facility. Each compressor had a 120 hp electric motor, cooling tower on the roof and was about 25 feet long. The starter windings were manually accessed by a large floor mounted lever and when they were up to speed you'd throw the lever the opposite way and slip it around a latch hook. Then fill all the drip cup oilers right away, then go to the next machine. When they were loaded down, and through chance were in close to in sync with each other, I was unable to run my surface grinder for finishing several hundred feet away. Sounded so cool though. They were cut up for scrap and replaced by a screw drive Ingersoll Rand, which broke down regularly. My babies NEVER missed a day, ever.

Nearly ten years (and over one century!) later and still runs like a top. Thank you, CSPM, for keeping the old girl in immaculate condition :)

The torque produced by that engine is amazing. I love the sound of it!

And no stupid music, thank you....great video

For me This is why I love old equipment. I'm more of an antique farm and construction equipment guy but it all fascinates me to no end. Designed by human brains with a slide rule and protractor, cast and machined without computers, assembled with precision and sweat & raw strength to do work in a place most will never even know it exists, and for the most part forgotten about after newer technology took it's place. If I could have a wish it would be to have the insane intelligence to comprehend such an undertaking and to have learned from those that wielded machines like this to life from scratch without modern assistance from computers. Purely amazing.

This is amazing. This engine will literally last forever with proper maintenance.
They literally do not make engines like this any more.
Made by hand. A work of mechanical art.

I worked for a midsized natural gas company in the Midwest, in Lakin, Kansas they had 3 of these units side by side, I so enjoyed watching them run, the facility was 40 years old back then and the oilers would walk by and wipe any dust or oil up right away, these engines looked like they were placed there yesterday.

Dang I love the full throttle sound. It's like a music. Who agrees?

Imagine how many millions of cycles this engines piston has traveled since 1917. The gigantic roller cam is a trip.

I worked at a coal mine in UK in the 1970s where we had two massive steam engines for winding men, materials and coal. They were amazing to watch in action. In the 1971 National Strike, as middle management, I took on the role of keeping alight 4 of the 8 boilers to keep the winders working. On the last day of the strike the coal feed conveyor broke and I worked through the night to fix it so normal production could start the next day.

Very impressive. This must be one of the largest surviving horizontal gas engines. Its amazing to think that the largest double acting horizontal gas engines had 60 inch bores and only slightly longer strokes and produced much more power. They must have been something really worth seeing. The biggest reciprocating engines were steam powered back then and were just enormous with some reaching 15, 000hp and weighing 1800 tons. There is a 1000hp vertical triple expansion steam engine in the UK near London that still runs and is just over 60 feet tall and that was medium sized !

I Remember casting wheels, bearing housings and other parts just like those in the video. I was working at McNally Pittsburg Foundry 1979.
I created tons of iron from pig, steel and returns in 2 4, 000 lb capacity electric furnaces there were 2 12, 000 furnaces also.I charged by hand . Every pound.
I adjusted the silicon and carbon content and poured at 2, 800* into ladles ranging from 300 lb to 10, 000 lb capacity.
I was involved in the heavy mold assembly and heavy cleaning and pouring also.

It's a little known fact, but this is the engine that actually powers the rotation of planet Earth.
