The Model 'E' was made from 1911 until 1923 according to
Clifford Caron in his article in the July-August 1968 Gas Engine
Magazine. It was the second model built by the M. Rumely Company of
LaPorte, Indiana. The first was the 25-45 Model 'B', a two
cylinder 9-1/2' x 12' built first in 1909. The Model
'F' was built about the same time as the model 'E'
but was a single cylinder engine with same size piston as the model
'E' which had 10' bore and 12' stroke. The Model
'E' 30-60 and Model 'F' 15-30 are advertised in the
1916 Gas Review Magazine as the only two models being built. They
were the only two models built by Rumely from 1914 to 1917
according to Clifford Caron in his article referred to above.
There were many more models made thru the years especially when
the light-weight Rumelys were begun in about 1924. 'Rumely'
Bill Krumweide, Voltaire, North Dakota says there were about
thirty-two different models sold by the Rumely people. He has
nearly all of these models in his collection.
R. B. Gray in his Development of the Agricultural Tractor in the
United States gives the following description for the 1911 Rimely
Oil Pull 30-60 H.P., 375 r.p.m., 2 cylinder twin horizontal engine
with cylinders sloping and offset from center line of crank to
reduce angularity of connecting rod on forward stroke.
Secor-Higgins kerosene carburetor with water injection;
make-and-break ignition with Bosch magneto; automatic throttle
governor; mechanical oiler; oil-cooling circulated by centrifugal
pump and draft induced through radiator by exhaust; expanding
shoe-type clutch; and spur gear final drive. Forward speed, 1.9
m.p.h. compressed air starter.
The early Model 'E' had round spokes in the front
wheels, with the center ridge on the rim pressed out of the face of
the wheel instead of a bolted on skid rim. The first 80 inch
diameter rear wheels had 16 spokes, later had 20 spokes. The front
wheels then had 10 spokes made of flat iron. A 1915 Rumely catalog
shows tractor number 1297 says Ted Worrall, Loma, Montana.
The following is from the Nebraska test number 8 conducted April
23 to May 11, 1920; Rimely Oil Pull Model 'E' 30-60 Serial
number 11521. Maximum load test; 75.60 horsepower developed on belt
and 49.91 horsepower on drawbar test. Drawbar pounds pull 10,025.
Bore 10' stroke 12', Rated speed 375 r.p.m., 1.9 mi. per
hr. weight 26,000 lbs.
The early insulation of the 'fixed' electrode in the
ignitor was a weak spot in the low-tension ignition systems. Sheet
mica was wrapped around the electrode and soon resulted in a
'short,' which would prevent producing the necessary hot
spark at the contact points. Later this condition was improved by
using tightly held mica washers, the outside of which was ground to
a smooth finish and prevented the entrance of moisture and dirt.
