6 HP Root & Vandervoort gasoline engine

My pride and joy is a 15 HP SPANG built in Butler, PA. It is a 2
cycle oil well engine which I restored (in ten months) and built a
trailer for. The picture was taken at the Portersville Show. Jake

This is a piece of equipment you don’t see very often. It is
a rock crusher. The nametag says ‘Joshua Hendy Machine Works
S.F. Cal.’ To the right and just below the name are the large
raised numbers 6 x 7 in the casting. That is the size of the
crushing jaws. It is powered by a 5 HP Fairbanks Morse gasoline
engine now converted to propane. I have completely restored the
crusher and the engine and painted them (battleship gray).

Back in the 20’s and before, these little crushers were used
extensively by prospectors looking for precious metals. They could
be hauled to the mine site with a few teams of mules. This one was
found by my friend while he was hunting for deer high in the
Siskijou Mountains about 20 miles north of the California border. I
will be taking it to the various shows in the summers, crushing
rock-to show it off! Courtesy of Lloyd Linderson, 2907 93rd Avenue,

‘This 4 HP Maynard engine is very unusual here on the West
Coast. They were built by the Jacobson Machine Co. of Warren, Pa.,
and sold by the Charles Williams Stores of New York City,’
writes Lloyd Linderson of 2907-93rd Ave., S.W., Olympia, Washington

‘This one had worked in a gold and silver mine in Northern
California during the 1930’s. I got it from the widow of a man
who had taken it in in lieu of wages for work at the mine.’

Linderson continues, ‘The engine is #M-10023-it is unique in
as much as the governor is built onto the side of the large timing
gear. It also has that obvious family resemblance to the Bullseye
engine. Took me about 2 years to restore it.’ Linderson adds
that he would like to hear from others who have Jacobson built
Maynard engines.

Harvey Wahl of Rt. 1, Box 61, Dundee, Minnesota 56126 sent this
picture of his 6 HP Root & Vandervoort gasoline engine, which
he bought in the Fall of 1979. The engine is now fully restored and
is shown annually at the Butterfield Thresherman’s Show in
Butterfield, Minnesota.

The engine was bought new in 1905 by Albert Larson, Westbrook,
Minnesota from the Farmers Elevator Company. It was used by Mr.
Larson in the barn on his farm to run a feed grinder. The engine
remained inside his barn from 1905 until it was removed by Wahl in
