IMPROVEMENTS IN OBTAINING MOTIVE POWER, AND IN THE MACHINERY OR APPARATUS EMPLOYED THEREIN.”
Year: 1873

page_text: LETTERS PATENT to Robert Stone, of Liverpool, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN OBTAINING MOTIVE
POWER, AND IN THE MACHINERY OR APPARATUS EMPLOYED THEREIN.”
PROVISIONAL SPECIFICATION left by the said Robert Stone at the
Office of the 'Commissioners of Patents, with his Petition, on the
12th August 1878.
I, ROBERT STONE, of Liverpool, in the County of Lancaster, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN ONTAINING.
MOTIVE POWER, AND. IN. THE MACHINERY. OR APPARATUS EMPLOYED, THEREIN," to be
as follows:-
This Invention relates to a novel application of leverage and pre-
ponderance of weight so as to obtain motive power therefrom.
A machine or apparatus constructed according to this Invention
consists of a spherical, cylindrical, or other suitably shaped centre.
This centre is carried on a shaft mounted in suitable bearings. The
centre is. pierced by two or more suitable glands, which glands form

page_text: bearings for vertical radial arms, which pass therethrough. These radial
arms are heavily weighted at their ends. The ends may be fitted with
antifriction rollers. The arms are divided into three portions by two
suitable stops or collars, so that the centre portion works through the
gland, and the stops provide against the arms being driven too far
through the gland. Approximate to the radial arms and centre is a rail,
cam, roller, wedge, or other suitable provision set-eccentrically with the
before-mentioned centre. This rail, cam, roller, wedge, or other suitable
provision is used for the purpose of driving the radial arms through the
glands in the centre as they rotate.
The rotation takes place in the following manner :-For example, say,
the rail, cam, roller, wedge, or other provision is situated on the right-
hand side of the apparatus, and so arranged as to throw or drive the
radial arms through the centre to the left as they rotate. The apparatus
being started by the preponderance of weight caused by the extra
leverage of the arms projecting through the centre being brought to the
left will cause the centre and carrying shaft to rotate, bringing the next
radial arm in sharp contact with the rail, cam, roller, inclined plane, or
other provision which drives or forces the radial arm through the centre,
and makes it a motor by the preponderance of weight and leverage.
Each arm in succession undergoes the same action of being driven
through the centre, and each successive preponderance of weight causes
the apparatus to rotate.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Stone in the Great Seal Patent Office
on the 10th February 1874.

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 OBTAINING MOTIVE POWER, AND
IN THE MACHINERY OR APPARATUS EMPLOYED THEREIN," upon the condition
(amongst others) that I, the said Robert Stone, my executors or
administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascer-
tain 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 Robert Stone, do hereby declare the
nature of my said Invention; and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement:-
This Invention relates to a novel application of leverage and pre-
therefrom.
ponderance of weight so as to obtain motive
power
A machine or apparatus constructed according to this Invention
consista, of, a spherical, cylindrical, or other suitably shaped centre.
This..centre.is. carried_on_a_shaft_mounted in suitable bearings. The
.centre is pierced by two or more suitable holes, which holes form
bearings for, radial arms, which pass therethrough. These radial armis
are heavily weighted at their ends. The ends may be fitted with anti-
.friction rollers. The arms are divided into three portions by two suitable
stops or collars, so that the centre portion works through the holes, and
the stops provide against the arms being driven too far through the holes.
Approximate to the radial arms and centre is a rail, cam, roller; wedge,
or other suitable provision set. eccentrically with the before-mentioned

page_text: centre. This rail, cam, roller, wedge, or other suitable provision is used
for the purpose of driving the radial arms through the holes in the centre
as they rotate.
The rotation takes place in the following manner :-For example, say,
the rail, cam, roller, wedge, or other provision is situated on the right-
hand side of the apparatus, and so arranged as to throw or drive the
radial arms through the centre to the left as they rotate. The apparatus
being started by the preponderance of weight caused by the extra
leverage of the arms projecting through the centre being brought to the
left will cause the centre and carrying shaft to rotate, bringing the next
radial arm in sharp contact with the rail, cam, roller, inclined plane, or
other provision which drives or forces the radial arm through the centre,
and makes it a motor by. the preponderance of weight and leverage.
Each arm in succession undergoes the same action of being driven
through the centre, and each successive preponderance of weight causes
the apparatus to rotate.
The apparatus may be connected' to shafting or gearing for driving or
applying motive power for any purposes for which power is required.
The apparatus may be checked or stopped by the application of any
known suitable breaks, as is well understood.
The before-going being the nature, object, and purposes of my Inven-
tion, I will now proceed, by the aid of the accompanying Drawing, to
describe how the same may be constructed and put into operation.
The apparatus may consist of a spherical, cylindrical, or other suitably
shaped centre A, mounted on a suitable shaft A³, running in bearings. 2
The centre piece A may be pierced by two or more suitable holes B, B¹,
which holes form bearings or guides for radial arms C, C³, C³, C³, which
pass therethrough. These radial arms are heavily weighted at their ends
with the weights D, the weights D being fitted with antifriction rollers E.
The centre A is provided with spring buffers F, F¹, F³, F³, to act as 3
cushions or buffers as the apparatus revolves. In connection with the
radial arms C and centre A is a rail, cam, wedge, or other suitable pro-
vision G, by preference made to oscillate, set eccentrically with the
before-mentioned centre. This rail, cam, wedge, or other suitable pro-
vision is used for the purpose of driving the radial arms through the 3
holes in the centre A as the arms rotate.

page_text: The rotation takes place in the following manner :-Say, the rail, cam,
wedge, or other suitable provision G is situated on the right-hand side of
the apparatus, and so arranged as to drive or throw the radial arms
through the centre to the left. The apparatus being started and rotated
by mechanical or manual means, the preponderance of weight by the
extra leverage of the radial arms being driven through the centre will
cause the centre and carrying shaft to rotate, and thus increased power
will be gained over the prime mover, and thus the apparatus becomes a
motor by the preponderance of weight and leverage.
Apparatus according to this Invention may be multiplied on a shaft,
and thus gain power, enabling small power engines and motors to do
increased work.
The apparatus may be fitted on to any existing shafting or machinery
with advantage, and the apparatus may be provided with four, six, eight,
3 or more radial arms, as may be deemed expedient.
Having now described and ascertained the nature, object, and
purposes of this Invention, and shown how the same may be put into
effect, what I claim as the Invention secured to me by Letters Patent
as aforesaid is, the improvements in obtaining motive power, and in the
machinery or apparatus employed therefor, as herein set forth and
described.
In witness whereof, I, the said Robert Stone, have hereunto set my
hand and seal, this Sixth day of February, in the year of our
Lord One thousand eight hundred and seventy-four.
