I went out to the Spring Steam Up at
www.roughandtumble.org today.
One of the guys who has a YouTube channel, Dave Richards ( Steam Powered Machine Shop ) was there with a steam powered buggy his Dad built on a 1953 IHC panel truck frame / running gear. The steam engine is a home made unit and his Dad helped the guy who originally made the steam engine machine it.
Matt brought out his Taylor Vacuum Pump engine along with a milker ( sorry, no cow ) to show how a farmer 90 or so years ago could have a powered milking machine without electricity.
One of the unique engines is this 4 hp Columbus "cam stopper" engine which was built about 1899.
As you can see in the video, the end of the sideshaft which controls the fuel charge and spark, only rotates when a fresh fuel charge is required.
It's a complicated design ( to get around patents ) and pretty rare.
Here's a steam engine that was installed in 1850 and was used continuously for the next 54 years at Jersey City Power Company.
This is a "walking beam" style of steam engine
And finally, a light
This is a carbon arc light. It's powered by 120 VAC and uses carbon rods to literally create an arc which lights up the area. These were used as street lights as electricity became more common. There would be a worker who would replace the carbon rods as needed ( daily or every other day ). This particular lamp is self adjusting.
Here's a slide show of the pictures I took today

Below is a "blown up" poster sized picture of an original Otto Gas Engine brochure from 1893. My friend Roger has both the original 17 hp Otto bevel gear engine from 1893 and the 6" x 10" brochure / catalog. Joe borrowed the original and had his friend do a high resolution scan. His friend then blew it up to poster size and has some "fancy computer program" which adds pixels to the original picture and had it printed on vinyl.
It looks fantastic
