Cool Me holding a piston ring for the 1913 485 hp Cooper engine

In addition to working on cub cadets, I like old iron and help out at Rough & Tumble in Kinzers Pa at the working museum. www.roughandtumble.org The piston ring I'm holding is out of a 1913 vintage 485 hp Cooper engine that developed 21,000 ft lbs of torque. It was originally run on natural gas and was a pump for moving natural gas thru the pipelines. This engine plus an additional six others were in Medina Ohio.

Here's me with the piston ring


The single flywheel is 14' in diameter and weighs 22,000 lbs. It has a 21-1/2" bore and a 36" stroke and is a "Tandem Double Acting" each pair of pistons has it's own cylinder casting and cooled in the center.

View from the front ( click for bigger pics)




A couple pics of the compressor




Here's how you bring an engine that weighs 150,000 lbs to TDC so you can start it. It's started with compressed air , 165 psi fed thru 2" steel pipe. The guy pumping is priming the oiling system.

Here's it's running on propane. Both ends and the center are saddle mounted to support the weights of the piston assembles. The large eccentrics run the intake valves on the top and the exhaust on the bottom

Here's a view of the ignition system and the smaller eccentrics for the oiling.

Here's one I took two weeks ago from the flywheel side. If you listen closely, you can hear when the air is switched off and it starts running on propane ( just a few seconds after the video starts)

Holy ****! That is huge! Don't think you'll be holding up the piston for us to see.

It would smash it like a bug. The engine weighs 150,000 lbs ( 75 tons)

There are a lot of good folks who help out. One of the guys is an engineer and designed a hydrogen system so they could run the 1868 Otto Langen engine. It is the first design of a combustion engine and is what got things moving as far as moving away from steam and into fuel fired engines.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
