This is a catalog illustration of Scheidler Machine Works about
1900. The machine work and engine assembly was done in the two
story building on the left. Boilers were built in the boiler shop
on the right. A completed Scheidler portable steam engine sits in
the yard between the buildings as does a boiler which has just been
built.

In the 1850s Reinhardt Scheidler was employed as a mechanic for
the Newark Machine Works in Newark, Ohio. By 1864 this company was
sold. Scheidler, along with Patrick McNamar, formed a partnership
company to build portable steam engines, boilers and sawmills.

After twenty years of operation in 1880, Scheidler had sold his
interest in the Scheidler-McNamar partnership and built a new plant
on South Third Street in Newark. The partnership was dissolved
because of Reinhardt’s differences with Patrick McNamar, who
replaced his father in 1868. Some of the differences were that
McNamar refused to build a traction steam engine until he had
finished building a spur gear differential, as he did not trust the
bevel gear differential. Another problem was that McNamar insisted
that all engine valve gear was double-ported balanced slide valve
type.

Scheidler went into the steam engine building business by
himself, and in his new factory could now build steam engines the
way he wanted to build them. In 1882 he built a traction engine
which sold for $1,000. This was a unique engine, as Scheidler had
not yet designed a differential gear, so this engine did not have a
differential but had two long levers which threw the bull pinion
out of gear on the side of the engine which the operator wished to
turn. This system was very unsatisfactory, as the gears were prone
to break and as Scheidler sold the engine with a warranty; the
engine was later fitted with a bevel gear differential.

Scheidler engines were built many different ways; the engine
could be purchased with a balanced ‘D’ valve or
Scheidler’s piston valve design. Other options were with or
without a clutch and with or without a super heater at the base of
the stack. The main drawback of the engines was Scheidler did not
use staybolts to fasten the crown sheet to the boiler but used a
crown sheet support that he patented. Scheidler’s design used
crown bars hot riveted lengthwise to the crown sheet. Each pair of
crown bars was spaced so that the head of a 5/8′ machine bolt
would be held in the slots of the crown bars. These bolts could be
spaced as desired during final assembly. The inside of the boiler
wagon top also had crown bars riveted to it, which supported
5/8‘ machine bolts. Nuts were fastened to
the 5/8‘ machine bolts which were
tightened to the desired tension.
