1908 Geiser Model "ZZ" Steam Engine
The Geiser model "ZZ" double cylinder steam engine was manufactured
by the Geiser Mfg. Co. of Waynesboro, Pennsylvania. The model "ZZ"
was the largest steam engine that Geiser Mfg. Co. manufactured in
1908, designed primarily for heavy hauling or plowing. It featured
a double cylinder 8 1/2 x 10 inch steam engine, which ran at only
260 rpm and developed 35 horsepower. The entire steam engine
was 23 feet long, with a 17 foot long boiler, 6 foot diameter rear
drive wheels, and 4 1/2 foot diameter front wheels. Included for this
size steam engine was a 540 gallon water tank, and a boiler that operated
with 160 pounds per square inch of pressure. The maximum forward or
reverse speed for this steam engine was only 2.38 mph. Another feature
that was included was a Moore water pump and injector which delivered
water through a double exhaust pre-heater. Overall, Pazandak was very
pleased with the features incorporated in the Geiser steam engine
and stated that "the excellent design and quality materials
makes this steam engine a 'Cadillac' in its class."
Included in all the pictures showing the Geiser model "ZZ" steam
engine is a companion, steam actuated, Geiser "Peerless" plow. According
to Pazandak, the plow had twelve 14 inch bottoms which were raised
and lowered by two long steam cylinders. The cylinders were linked
to the steam engine, and when the operator turned a valve, steam was
forced into the cylinders. The reaction of the steam being forced
into the cylinders lifted the twelve bottom plow out of the ground.
Conversely, when the operator turned the valve the opposite way, the
steam was forced out of the cylinders and the plow was dropped to
the ground. The front of the plow was clamped to the rear of the steam
engine, and the rear wheel of the plow was turned by a cable connected
to the front axle. A point that should be emphasized is that this
plow is very unique, and represents a very early attempt by a manufacturer
to design a fluid-based implement power lift. Steam as a fluid, however,
had distinct limitations when used in a cylinder, and thus it was
replaced by hydraulic oil in all implement power lifts which are used
on plows and farm machinery today.
