WHEREAS we are in possession of an Invention for "IMPROVEMENTS IN
MECHANISM FOR TRANSMITTING POWER AND INCREASING THE EFFECTIVENESS OF THE
Same,” and have petitioned Her Majesty to grant unto us, our executors,
administrators, and assigns, Her Royal Letters Patent for the same, and

page_text: NOW KNOW YE, that we, the said Richard Bruno Hamel and James
Brower Holden, do hereby declare that the following Complete Specifi-
cation, under our hands and seals, fully describes and ascertains the
nature of the said Invention, and in what manner the same is to be
performed, in and by the following statement, reference being had to the
accompanying Drawings forming a part of this Specification, and to the
letters and figures marked thereon :--
This Invention relates to improvements in mechanism for transmitting
power and increasing the effects of the same, whereby a smaller amount
of driving power is required to accomplish a greater quantity of work,
and by the application of which to machinery driven by any of the well-
known powers the effectiveness of the same is increased and the driving
power applied thereto made to perform much greater results. It is more
especially designed to be applied as a hoisting apparatus and to presses
of various kinds, as well as to machinery driven by steam or other
power. When used as a separate machine it forms a most effective
hoisting apparatus, and also a most effective machine for driving presses
of various kinds; and when attached or applied to other machinery as
an auxiliary it will greatly increase the effectiveness of the power
employed, and add greatly to the results of the same in the amount of
work performed.
For these purposes we use or employ an independent intermediate
wheel, weighted or loaded to a proper and suitable extent, in connection
with a pinion wheel and an outer annular wheel. The said pinion wheel
is fixed and secured on a shaft that rotates and has bearings within the
hollow shaft of the outer wheel, and gears with the intermediate wheel.
The intermediate wheel is boxed or flanged, and its flanges work in
contact with the inner surface of the rim of the outer wheel, upon which
it is supported, and drive the outer wheel by friction. This intermediate
wheel is weighted or loaded proportionately to the amount of driving
power applied and the resistance to be overcome, and to such an extent
that while in operation it will retain a position nearly perpendicular to
or nearly directly under the pinion, and supported, as before stated, upon
the inner side of the rim of the outer wheel. The driving power being
applied to the shaft upon which the pinion is secured, motion is trans-
mitted through the medium of the said pinion to the loaded intermediate
wheel, and through the medium of this intermediate wheel to the outer
annular wheel, which in turn conveys it, through the medium of any

page_text: suitable mechanical devices, to any machinery to which our mechanism
may be attached. When the pinion wheel is put in motion it acts upon
the periphery of the intermediate wheel in such a manner as to move it
from its position directly underneath the pinion, and to roll it a short
distance upward on the rim of the outer wheel, which is thus put in
motion, as by this means the weight of the intermediate wheel, loaded as
before mentioned, is brought to bear upon the rim of the outer wheel,
and the amount of power expended in bringing it into this position is
only so much as may be requisite to impart a rolling motion to the
weighted or loaded intermediate wheel. If, for instance, the diameter
of the intermediate wheel is thirty-three inches, that of the pinion
twenty-two inches, and the inner diameter of the outer wheel is eighty-
eight inches, and the intermediate wheel is loaded to the extent of, say,
two thousand pounds, it is obvious that the amount of power necessary
to be applied to the pinion in order to give a rolling motion to the
intermediate wheel and cause it to move a short distance up the rim of
the outer wheel is small in proportion to and compared with the amount
of power exerted on the rim of the outer wheel by the weight of the
intermediate wheel. The proportions and sizes just mentioned of the
several wheels and amount of loading given to the intermediate wheel
are adapted for a driving power equal to six or seven horse power, but
the proportions may be varied, and the sizes of the several wheels and
amount of loading given to the intermediate wheel may be increased or
diminished when used in connection with a larger or smaller amount of
driving power than that above mentioned.
The essential and peculiar features of this Invention arc, that the
comparatively small amount of power requisite to impart a rolling
motion to the loaded intermediate wheel places the latter in a position in
which its weight acts on the rim of the outer annular wheel and drives
the same, and in consequence of this the power imparted by the said
outer wheel to machinery to which it may be attached is greater than
the power applied to the pinion.
In order that the said Invention may be fully understood we shall
now proceed more particularly to describe the same, and for that purpose
we shall refer to the several Figures on the Sheet of Drawings hereunto
annexed, in which similar letters of reference indicate corresponding
parts throughout all the Figures.
Fig. 1 of the Drawings represents a side elevation of our improved

page_text: mechanism; Fig. 2 is a transverse vertical section of the same; and
Fig. 3 is a corresponding longitudinal vertical section..
The
A is the outer annular wheel; B is the independent intermediate
wheel; and C is the pinion wheel. The outer wheel A is made of such
dimensions and strength as may be most suitable for the amount of
power to be applied thereto, and is provided with any convenient number
of arms a, a, a, a, one end of each of these arms being bolted or other-
wise secured to the rim b, and the other end secured in like manner to
one of the hubs c, c, which carry the hollow shafts D, D', of this wheel.
These shafts D, D³, have suitable bearings in the pillow blocks H, H,
secured to and-supported by any suitable-frame E. The shafts D, D¹,
are made hollow or cylindrical for the purpose of receiving the shaft F
of the pinion, which has bearings and runs within the same. The
independent intermediate wheel B is made in the form of a boxed or
flanged gear wheel, and it is supported on the inner surface of the rim b
of the outer wheel, its flanges d, d, being in contact with the plain inner
surface of the rim b and causing friction thereon, by means of which it
drives the outer wheel A. This intermediate wheel B gears with the
pinion C, and is weighted or loaded, as already stated, proportionately to
the driving power applied and the resistance to be overcome.
loading may be secured to the wheel B in any convenient and suitable
manner, and should be of sufficient weight or amount to keep the
intermediate wheel nearly perpendicular to or nearly directly under the
pinion C, and prevent the same being carried too far upward on the
rim b. i, i, are guides or rods secured to the inner side of the rim b for
the purpose of guiding the wheel B and keeping it in position. The
driving power is applied to the shaft F of the pinion C, which being set
in motion imparts a rolling motion to the intermediate wheel B by
means of the gearing already mentioned, and causes it to move a short
distance upward on the rim b of the outer wheel, which is thus put in
motion as the weight of the intermediate wheel is brought to bear
thereon. If the intermediate wheel B is loaded to any considerable
extent it will, when brought into the position just mentioned, exert a
greater amount of power upon the rim of the outer wheel than that
expended in giving it this rolling motion and placing it in the position
in which its power is exerted, and consequently the power given off or
imparted from the shaft D' will be greater than that received by the

page_text: The mechanism herein-before described has been practically tested by
attaching the same to the machinery of a saw mill driven by steam
power, when it was found that by its use the engine could more easily
accomplish the work with forty pounds pressure of steam than it had
previously done with eighty pounds pressure of steam. In this instance
the weight of the intermediate wheel was about twenty-four hundred
pounds, the diameter of the pinion was twenty-two inches, that of the
intermediate wheel was thirty-three inches, and the minor diameter of
the outer wheel eighty-eight inches.
The wheel A may if desired be provided with teeth on the inner side
of its rim b, so as to gear with the intermediate wheel B, in which case
the flanges d, d, would be left off, but we consider the construction
above described as being preferable.
Having now described and particularly ascertained the nature of the
said Invention, and the manner in which the same is or may be carried
into effect, we would observe that we do not confine ourselves to the
precise details or arrangements herein-before described or referred to so
far as regards the proportionate dimensions of the several wheels, the
amount of loading on the intermediate wheel, and the modes of applying
or attaching our improved mechanism to other machinery, as these may
be varied without deviating from the principles or main features of the
said Invention; but what we claim as our Invention is, the arrangement
of the loaded or weighted independent intermediate wheel with the outer
annular wheel and pinion wheel, substantially as herein described, the
same to be used either as a machine for hoisting, pressing, and other
purposes, or to be attached as an auxiliary to other machinery for the
purpose of transmitting power and increasing the effect of the same.
In witness whereof, we, the said Richard Bruno Hamel and James
Brower Holden, have hereunto set our hands and seals, the
Eighth day of April, One thousand eight hundred and seventy.
