The Rogge Engine

HERE IS A CREATION OF DELBERT WOLFE, 1616 E. CLINTON STREET,
FRANKFORT, INDIANA. WE THINK IT AN EXCELLENT JOB AND WE LET DELBERT
GIVE YOU THE FACTS. Ed.

I am taking the liberty of enclosing photograph of a steam
working model which I have just completed, of a Gaar-Scott 25
horsepower general purpose farm tractor which I hope you will see
fit to publish in your magazine.

This is a two-inch scale model and over-all length is 43 inches,
height, ground to top of stack, 24 inches; rear wheels 13 inches in
diameter; front wheels 7 inches in diameter, and flywheel 7 inches
in diameter.

It has 185/8 inch flues, 16? inches long
made of copper tubing. Size of grate 4 and seven eight inches by 7
inches. Has two cylinders size each, 13/8
inches diameter by 13/4 inch stroke. It is
equipped with safety valve, steam gauge, whistle and boiler feed
pump operated from the crank shaft. Boiler is 6? inches in diameter
and 28 inches long. working steam pressure 100 to 120 pounds. Has
reverse, governors, lubricator and friction clutch for road
movement. Total weight of engine ready to run is 210 pounds. It
fires on coal or wood. For your information I had this engine at
the Indiana State Fair belted to a Viking elevator for
demonstration and received many complimentary remarks.

E. J. Roggeman, 4430 Newton Ave., North, Minneapolis, Minn.,
sends us this picture of the steam engine he is building. Mr.
Roggeman says ‘I call it ‘The Rogge Engine’. It is
complete, reverse gear, cylinder pump, lubricator and controls,
ready to be mounted on a 14′ diameter horizontal boiler.
Cylinder size is 4′ x4’crank disc is 8′ diameter,
whereas the Belt Wheel is 17′ in diameter.

‘The engine is ready to run if I can find some steam supply.
Am now working on building the boiler and when it is finished I
hope to have more pictures for the ALBUM and possibly a story as to
my experience in building same and work with other
engines.’
