THE EXPERIENCE OF TWENTY YEARS in designing, building and
operating Steam Engines in almost all parts of the country, doing
all kinds of work, under all the different circumstances and
and perfect in the Engines and Boilers represented in this cut
The Most Perfect Portable Engine now in the
Market.
Some of the points in which it excels all others are as follows
: The Engine Cylinder is encased in (and its covering forms) the
upper part of the dome, thereby avoiding condensation in the
cylinder and steam-pipes, PREVENTING most, if not all, the
POUNDING, STRAIN & BREAKAGE OCCASIONED BY WATER IN THE
CYLINDER, which does more to destroy the Engine than all the work
it performs. The pillow blocks are connected centrally with the
cylinder by an iron frame, which receives the strain in a direct
line and is not deflected by the action of the Engine, thus tending
to keep in line, instead of getting out, as in the old style. The
heater is also encased in the base of the dome, the pipes secure
from frost; still it receives the exhaust steam in the usual way.
It has the Compound Crank and two Drive Pulleys. To clean the
Boiler it is only necessary to separate a ground joint in the dome,
and you have free access to the water surface of the Crown Sheet,
Tubes and Fire Box, and as we have left out all the bad and
retained all the good qualities of the ordinary Engines, and having
the mechanical department under the direction of the Pioneer in
Portable Engine building, feel warranted in saying that this is
SUPERIOR to any Engines built in this or any other country. These
improvements being entirely our own, and secured by Letters Patent,
can only be obtained at our Works.
