Year: 1878

page_text: LETTERS PATENT to Alexander Melville Clark, of 53, Chancery Lane, in the
County of Middlesex, Patent Agent, for the Invention of "IMPROVED MOTIVE-
POWER APPARATUS." A communication from abroad by Casper Huebner, of
Newark, in the County of Essex, and Philip John Kohberger, of Passaic, in
the County of Passaic, both in the State of New Jersey, United States of
America.
Sealed the 1st October 1878, and dated the 23rd April 1878.
PROVISIONAL SPECIFICATION left by the said Alexander Melville Clark at
the Office of the Commissioners of Patents on the 23rd April 1878.
ALEXANDER MELVILLE CLARK, of 53, Chancery Lane, in the County of Middle-
sex, Patent Agent. "IMPROVED MOTIVE-POWER APPARATUS." [A communication
from abroad by Casper Huebner, of Newark, in the County of Essex, and Philip
John Kohberger, of Passaic, in the County of Passaic, both in the State of New
Jersey, United States of America.]
This Invention relates to that class of motors in which power is stored and after-
wards given out so as to be effective in performing work.
The Invention consists in a shaft having two oppositely arranged cranks, which
are connected with levers which carry mercury chambers and are connected with
hand levers. The shaft is provided with fly wheels and with a wheel for receiving
the power-transmitting belt.
In the following description, although the Invention is described as applied to a
hand car, it is to be understood that it is not confined to this use.
As applied to a hand car, the crank shaft would be journalled in a frame carried
on a platform mounted on running wheels, the said crauk shaft having two heavy
fly wheels at each end, and in the middle the pulley which receives a belt, which
also passes around a pulley on the axle of the wheels of the car.
A pair of weighted levers are fulcrumed at the lower portion of the frame of the
and are connected by connecting rods with the cranks, and are also connected

projecting from the upper part of the car frame. A seat is attached to the frame
between the hand levers and over the fulcrum of the weighted levers. Below the
seat there is a double or divided lever which extends back beyond the belt and
supports a tightening pulley which rests upon the belt.
Upon each of the levers connected to the cranks a box is secured, which extends
equally on both sides of the fulcrum of the lever, and in these boxes bottles, which
are partially filled with mercury, are placed.
The operation of the machine is as follows:-The person desiring to propel the
car sits in the seat and operates the hand levers until a high velocity is attained in
the fly wheels. The power thus accumulated is given out for a great length of time
and the mercury in the bottles assists in prolonging the motion.
When the machine is working to its full capacity and it is desired to stop the
car, the tightening pulley is lifted from the belt.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Alexander Melville Clark in the Great Seal Patent Office on
the 22nd October 1878.

ALEXANDER MELVILLE CLARK, of 53, Chancery Lane, in the County of Middle-
Patent Agent. IMPROVED MOTIVE-POWER APPARATUS." A communication
from abroad by Casper Huebner, of Newark, in the County of Essex, and Philip
John Kohberger, of Passaic, in the County of Passaic, both in the State of New
Jersey, United States of America.
This Invention relates to that class of motors in which power is stored and after-
wards given out so as to be effective in performing work.
The Invention consists in a shaft having two oppositely arranged cranks which
are connected with levers which carry mercury chambers and are connected with
hand levers. The shaft is provided with two heavy fly wheels and with a wheel
for receiving the power transmitting belt.
In the following description, the motor will be described as applied to a hand car,
but I do not confine myself to this use.
Figure 1 in the accompanying Drawing is a plan view of the improved motor
as applied to a hand car. Figure 2 is a vertical section taken on line x-x in
Figure 1.
Similar letters of reference indicate corresponding parts in the two Figures.
A is a small platform car mounted on wheels b, c, and carrying the frame B, in
which is journaled a shaft C having formed on it two oppositely arranged cranks
d, d', and having at each end a heavy fly wheel D, and in the middle a pulley E,
which receives a belt e, which also passes around a pulley f on the axle of the
wheels b.
Levers g, which are fulcrumed at h in the lower portion of the frame B, are con-
nected with the cranks by connecting rods i, and are connected at their free ends
by rods j with the hand levers k which are fulcrumed in standards 7 that project

page_text: from the upper part of the frame B. A seat E is attached to the frame B between
the hand levers and over the fulcrum of the levers g. Below the scat F there is a
double or divided lever m which extends beyond the belt e and supports a tightening
pulley n which rests upon the belt.
Upon each of the levers g a box o is secured which extends equally on both sides
of the fulcrum of the lever. In these boxes are placed bottles p which are partly
filled with mercury.
The operation of the machine is as follows:-The person desiring to propel the
car sits in the seat F and operates the levers k until a high velocity is attained in
the fly wheels D. The power thus accumulated is given out for a great length of
time, and the mercury in the bottles p assists in prolonging the motion.
When the machine is working to its full capacity and it is desired to stop the
car, the tightening pulley n is lifted from the belt.
Having described the nature of the Invention, and the manner of performing the
game, I declare that what I claim as the Invention to be protected by the herein-
before in part recited Letters Patent is, the combination of the shaft C having
oppositely arranged cranks d, d', and fly wheels D, the levers g having the vessels p
partly filled with mercury, and the hand levers in combination, substantially as
herein shown and described.
In witness whereof, I, the said Alexander Melville Clark, have hereunto set
my hand and seal, this Sixteenth day of October, in the year of our Lord
One thousand eight hundred and seventy-eight.
