page_text: LETTERS PATENT to Theodore Bourne, of the City, County, and State
of New York, in the United States of America, at present residing at
34, Woburn Place, London, in the County of Middlesex, for the Inven-
tion of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR TRANSMITTING
MOTION," A communication from abroad by Mathaus Kaefer, of
Factoryville, in the County of Richmond and State of New York,
in the United States of America.
Sealed the 3rd January 1865, and dated the 19th July 1864.
PROVISIONAL SPECIFICATION left by the said Theodore Bourne at the
Office of the Commissioners of Patents, with his Petition, on the
19th July 1861.
I, THEODORE BOURNE, of the City, County, and State of New York, in the
United States of America, at present residing at 34, Woburn Place, London,
in the County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR TRANSMITTING
MOTION," (a communication from abroad by Mathaus Kaefer, of Factoryville,
in the County of Richmond and State of New York, in the United States
of America,") to be as follows:-
This Invention consists in supporting the fly-wheel shaft in the ends of two
radial arms, which swing on a rock shaft in such a manner that the fly-wheel
shaft with its appendages oscillates in an arc described around the centre of
the said rock shaft, and that all the friction created by the oscillating or
Price 8d.1

page_text: reciprocating motion of the fly wheel and fly-wheel shaft is thrown upon the
journals of the rock shaft. The loss by friction is very small, and the driving
pulley, which is secured to the fly-wheel shaft, remains always at the same
distance from the driven pulley, which runs on the rock shaft, so that the
driving belt retains an uniform tension. The shaft to which the fly wheel and
driving pulley are attached bears on its ends two discs, and it is supported by
means of hinged guide rods that are secured to eccentric wrist pins, which
are fastened in the faces of the discs. The fly-wheel shaft has its bearings in
radial arms, which are rigidly secured to an arbor that rocks in stationary
standards or hangers, and when the fly wheel shaft is rotated it is caused by
the action of the guide rods and eccentric wrist pins to assume an oscillating
motion in an arc described from the centre of the arbor or rock shaft. The
rotary motion of the fly-wheel shaft is transmitted by means of a belt which
runs on the driving pulley to a pulley that is placed loosely on the rock shaft,
and the width of which is such that it affords room for another belt for the
purpose of communicating the motion to the desired working machines.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Theodore Bourne in the Great Seal Patent Office
on the 16th January 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THEODORE
BOURNE, of the City, County, and State of New York, in the United States
of America, at present residing at 34, Woburn Place, London, in the County
of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of July, in the year of our Lord One
thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,the
said Theodore Bourne, Her special license that I, the said Theodore Bourne,
myexecutors,administrators, and assigns, or such others as I, thesaid 'Theodore
Bourne, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter 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 "IMPROVEMENTS IN MACHINERY OR
APPARATUS POR TRANSMITTING MOTION," a communication to me from abroad by
Mathaus Kaefer, of Factoryville, in the County of Richmond and State of New

page_text: York, in the United States of America upon the condition (amongst others)
that I,the said Theodore Bourne, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seal, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Theodore Bourne, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):
This Invention consists in supporting the fly-wheel shaft in the ends of two
radial arms, which swing on a rock shaft in such a manner that the fly-wheel
shaft with its appendages oscillate in an arc described around the centre of
the said rock shaft, and that all the friction created by the oscillating or
reciprocating motion of the fly wheel and fly-weel shaft is thrown upon the
journals of the rock shaft. The loss by friction is very small, and the driving
pulley, which is secured to the fly-wheel shaft, remains always at the same
distance from the driven pulley, which runs on the rock shaft, so that
the driving belt retains an uniform tension. The shaft to which the fly
wheel and driving pulley are attached bears on its ends two disks, and it is
supported by means of hinged guide rods that are secured to eccentric wrist
pins, which are fastened in the faces of the disks. The fly-wheel shaft has its
bearings in radial arms, which are rigidly secured to an arbor that rocks in
stationary standards or hangers; and when the fly-wheel shaft is rotated it is
caused by the action of the guide rods and eccentric wrist pius to assume
an oscillating motion in an arc described from the centre of the arbor or
rock shaft. The rotary motion of the fly-wheel shaft is transmitted by means
of a belt which runs on the driving pulley to a pulley that is placed loosely
on the rock shaft, and the width of which is such that it affords room for
another belt for the purpose of communicating the motion to the desired
working machines.
And in order that the Invention may be fully understood and readily
carried into operation, I will proceed to describe the accompanying Sheet of
Drawings, reference being had to the figures and letters marked thereon.
Fig. 1 is an elevation, and Fig. 2 a plan of the improved machinery or
apparatus for transmitting motion.
The shaft A, to which the fly wheel B and driving pulley C are attached,
bears on its ends two disks D, and it is supported by means of hinged guide

page_text: '
rods E that are secured to eccentric wrist pins a, which are fastened in the
faces of the disks D. The fly-wheel shaft A has its bearings in the radial
which are secured to an arbor b that rocks in stationary standards or
hangers G, and when the fly-wheel shaft is rotated it is caused by the action
of the guide rods E and eccentric wrist pins a to assume an oscillating motion
in an are described from the centre of the arbor or rock shaft b. The motion of
the rock shaft is necessarily very limited, and the friction of its journals in
the standards G is therefore quite small and of little account.
The rotary
motion of the fly-wheel shaft A is transmitted by means of a belt H which
runs on the driving pulley C to a pulley I that is placed loosely on the rock
shaft b, and the width of which is such that it affords room for another belt
for the purpose of communicating the motion to the desired working
machines. The pulley C in oscillating with the fly-wheel shaft A turns in an
arc described from the centre of the rock shaft b, and the tension of the
belt H is not interfered with by the oscillating motion of the pulley C.
Having thus fully described the Invention, as communicated to me by the
within-named Mathaus Kaefer, I declare that what I claim as new and desire
to secure by Letters Patent is, the combination and arrangement of the shaft
A, guide rods E, E, and fly wheel B, with the arms F, F, and rock shaft b, in
the manner and for the purposes herein shewn and described.
In witness whereof, I, the said Theodore Bourne, have hereto set
my hand and seal, this Eleventh day of January, One thousand eight
hundred and sixty-five.
THEODORE BOURNE. L.S.)
