page_text: LETTERS PATENT to Alfred Vincent Newton, of the Office for Patents,.
66, Chancery Lane, in the County of Middlesex, Mechanical Draughts-
man, for the Invention of "IMPROVED APPARATUS FOR TRANSMITTING
MOTIVE POWER "A communication.
Sealed the 16th April 1859, and dated the 19th November 1858.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent Newton
at the Office of the Commissioners of Patents, with his Petition, on the
19th November 1858.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Mechanical Draughtsman, do hereby declare the
nature of the said Invention for "IMPROVED APPARATUS FOR TRANSMITTING
MOTIVE POWER," to be as follows:-
This Invention relates to the employment of a peculiar arrangement of
balance or fly wheel and cranks for the purpose of transmitting motion in
machinery, whereby the momentum of the fly wheel is rendered more effective
in carrying the cranks past their dead points than when a wheel is applied in
the ordinary manner in combination with cranks, and whereby, in connection
with the use of a load at one point in the periphery of the wheel, the
centrifugal force generated in the wheel is rendered available as motive
power.
On a fixed railway a carriage is mounted, which carries the fly-wheel shaft
provided at its opposite ends with a crank. One of these cranks is connected
by means of a rod with a fixed point, and the other by means of a rod to the
motive-power engine. The carriage itself is connected by a central connecting
rod with the machine to be driven, rotary motion being communicated to
the crank shaft through the reciprocating rod that connects it with the motive-

page_text: power engine the carriage is caused to move backwards and forwards on the
railway a distance equal to the throw of the cranks, and this motion is com-
municated to the machinery required to be driven, the rotation of the fly wheel,
whether weighted or not, carrying the crank smoothly over its dead points.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alfred Vincent Newton in the Great Seal Patent Office
on the 18th May 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of November, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Alfred Vincent Newton, Her special that I, the said
Alfred Vincent Newton, my executors, administrators, and assigns, or such
others as I, the said Alfred Vincent Newton, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time and
at all times thercafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVED APPARATUS FOR TRANSMITTING MOTIVE POWER," being a com-
munication from abroad, upon the condition (amongst others) that I, the said
Alfred Vincent Newton, by an instrument in writing, under my hand and scal,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Alfred Vincent Newton, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say):-
This Invention, as communicated to me by my foreign correspondent, relates
to the employment of a peculiar arrangement of balance or fly wheel and cranks
for transmitting motion in machinery, and rendering the momentum of the fly

page_text: wheel more effective in carrying the cranks past their dead points, than when a
wheel is applied in the ordinary manner in combination with cranks, whereby
in connection with the use of a load at one point in the periphery of the wheel,
the centrifugal force generated in the wheel is rendered available as motive
power.
The Invention is illustrated in the accompanying Drawing, in which Fig. 1
is a side view, and Fig. 2 a plan view of the improved apparatus. Similar
letters of reference indicate corresponding parts in both Figures.
A, A, B, B, represents a stationary frame; B, B, being parallel horizontal
rails or ways for supporting a carriage C, provided with flanged wheels
D, D, D, D, upon which the carriage traverses over the ways B, B. The
carriage C has also two rollers E connected with it by hangers F, one on each
side, which rollers are situated under the rails or ways B, B, to confine the
carriage C to the said ways. G, G, are journal boxes secured to the carriage C
to receive the journals of a horizontal shaft H, which is arranged transversely
to the ways B, B, and which carries a fly or balance wheel I loaded at one
point in its periphery with a weight J. On one end of this shaft H there is a
crank K, to whose wrist pin a is connected one end of a rod L, whose other
end is to be connected to the motor from which the power to be employed is
derived; and to the opposite end of said shaft there is secured another crank M
which is represented as being slotted to permit the adjustment of its wrist pin
6 nearer to or further from the shaft, as may be desired. To the wrist pin b
is attached one end of a connecting rod N, whose other end is connected with
a pin c, secured in a stationary standard T erected upon the stationary frame
A, A, B, B; Q is a rod, one end of which is connected by a joint pin d to the
carriage C, the other end is to be connected with the machinery to be driven.
The cranks K, M, may be set at any angle to each other, but I consider it
best to set them at an angle of ninety degrees. The weight J should be set
about from thirty degrees to forty-five degrees in advance of the crank M.
The relative lengths of the cranks K and M, that is to say, the relative
distances of their respective wrist pins from the axis of the shaft H is not of
great importance, but I prefer that the crank K should have its pin at the
greater distance from said axis. The crank pin 6 is set at a distance from the
axis equal to half the desired length of motion of the rod Q.
The operation of the above-described apparatus is as follows:-Motion
given in a longitudinal direction to the rod L causes the revolution of the
crank K, shaft H, wheel I, and crank M. The revolution of the crank M
causes the carriage C to receive a reciprocating motion on the ways B, and to
impart motion through the rod Q to the machinery to be driven, the length of

page_text: stroke of the said carriage being equal to twice the distance of the crank pin b
from the axis of the shaft. The fly or balance wheel. I carries the driving
crank K over its dead points without any jar, and with more ease than when
arranged in stationary bearings, as it is assisted by the momentum of the
carriage C; and the centrifugal force of the weight J assists in producing the
longitudinal movement of the carriage C. The length of stroke of the rod L
is only partly dependent on the length of the crank K, and is varied without
producing any variation in the stroke of the carriage C and rod Q, by turning
either crank to a different position on the shaft relatively to the other. The
rod L has the greatest length of stroke when the cranks are at an angle of
one hundred and eighty degrees or in opposite positions, and the least length
when they coincide with each other, or have the centres of their pins a and b
in the same plane radiating from the axis of the shaft.
The same combination of parts may be used to great advantage without the
weight J on the balance wheel in driving vertical reciprocating saws, pumps,
or other vertically reciprocating machines or parts of machines which require
a greater application of power in the downward than in the upward stroke;
the carriage in such case being arranged to work in line or parallel with the
saw or other mechanical device which is to receive the motion, and the two
cranks being set at right angles to each other or thereabouts. The weight of
the carriage, fly wheel, and shaft aids the descent of the saw, and also helps the
crank K past its "dead centres."
Having now set forth the nature of the Invention of "Improved Apparatus
for Transmitting Motive Power," as communicated to me from abroad, and
explained the manner of carrying the same into effect, I wish it to be under-
stood that under the above in part recited Letters Patent I claim, transmitting
motive power through a crank shaft and traversing carriage operating as
above described.
In witness whereof, I, the said Alfred Vincent Newton, have hereunto
set my hand and seal, the Eighteenth day of May, in the year of
our Lord One thousand eight hundred and fifty-nine.
