IMPROVEMENTS IN STEAM ENGINE GOVERNORS
Year: 1855

page_text: LETTERS PATENT to George Taylor, of Liverpool, in the County of
Lancaster, Merchant, (of the firm of Jacot, Taylor, and Tipper, 22,
Water Street,) for the Invention of "IMPROVEMENTS IN STEAM ENGINE
GOVERNORS."A communication.
PROVISIONAL SPECIFICATION left by the said George Taylor at the
Office of the Commissioners of Patents, with his Petition, on the
9th May 1855.
I, GEORGE TAYLOR, of Liverpool, in the County of Lancaster, Merchant, (of
the firm of Jacot, Taylor, & Tipper, 22, Water Street,) do hereby declare the
nature of the Invention for "IMPROVEMENTS IN STEAM ENGINE GOVERNORS " to be
as follows:-
The object of the Invention is to obtain in a governor universal motion in
an equatorial form with the driving spindle, in whatever position relative to a
given plane the instrument may be subjected to. And the Invention consists
in the combined arrangement of one or two bars or shafts (as circumstances
may require) loaded on each of the ends with equal weight or resisting
centrifugal force and transversely fixed, oscillating upon a single centre in the
slot or crevice of a driving spindle, (which may be placed in any position to

page_text: suit convenience,) and a spring or springs so adjusted as to resist the centri-
fugal force of said loaded bar or bars. A single oscillating bar with the
resistance of a spring at the centre will be capable of universal motion,
sudden oscillating changes of position, such as the instrument would be liable
to in marine uses, which would cause the centrifugal force to revolve for a
time elliptically to the driving spindle; I therefore apply an additional bar
transversely fixed on the same centro with the first, and attached by leaders to
one sliding collar, which enforces in all circumstances of sudden changes of
position equatorial centrifugal motion with the driving spindle.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Taylor in the Great Seal Patent Office on the
27th September 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
TAYLOR, of Liverpool, in the County of Lancaster, Merchant, (of the firm of
Jacot, Taylor, and Tipper, 22, Water Street,) send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of May, in the year of our Lord
One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said George Taylor, Her special licence that I, the said George Taylor,
my executors, administrators, and assigns, or such others as I, the said
George Taylor, 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
STEAM ENGINE GOVERNORS," (a communication,) upon the condition (amongst
others) that I, the said George Taylor, 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 George Taylor, 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 thereof (that is to say):-

page_text: The nature of the Invention consists in the combined arrangement of one
or two bars or shafts (as circumstances may require), loaded on each of the
ends with equal weight or resisting centrifugal force, and transversely fixed,
oscillating upon a single centre in the slot or clevice of a driving spindle
(which may be placed in any position to suit convenience), and a spring or
springs so adjusted as to resist the centrifugal forco of said loaded bar
or bars.
The object of the Invention is to obtain in a governor universal motion in
an equatorial form with the driving spindle, in whatever position relative to a
given plane the instrument may be subjected to.
A single oscillating bar with the resistance of a spring at the centre will
be capable of universal motion, sudden oscillating changes of position, such as
the instrument would be liable to in marine uses, which would cause the
centrifugal force to revolve for a time ecliptically to the driving spindle; I
therefore apply an additional bar transversely fixed on the same centre with
the first, and attached by leaders to one sliding collar, which enforces in all
circumstances of sudden changes of position equatorial centrifugal motion
with the driving spindle.
To enable others to better understand and use the Invention I refer to the
Drawings annexed.
Figure 1 in its main features represents a front view of the instrument
when not in motion.
Figure 2 represents a separate view of the male and female bars or shafts
and centrifugal balls.
A, A, Figure 1, represents the driving spindle; b, b, b, b, Figure 1, repre-
sents two bars or shafts, passing through each other and oscillating on the
centre at L; c, c, c, c, Figure 1, represents centrifugal balls, all being of equal
weight. D, Figure 1, represents a spring attached to a collar m, which can
be removed to alter the resisting force of the spring as may be desired, the
opposite end of said spring being joined to the sliding collar n, which is
geared to the oscillating shafts by the wires g, g. E, Figure 1, represents a
sliding collar with an endless slot or groove, which is penetrated by the
fork of rock shaft h. f, f, Figure 1, represent rods or leaders which connect
the oscillating bars to the sliding collar E. I, Figure 1, represents a pully
wheel by which motion is transmitted from the engine. Imaginary lines
k, k, k, k, represent the elongated position of the oscillating bars when in full
motion.
It will be seen from the above description that when the instrument is not
in motion, that the oscillating bars are drawn by force of the spring in a line

page_text: as nearly as possible with the driving spindle, but when motion is transmitted
from the engine the balls are inclined by centrifugal force to the position of
imaginary lines k, k, k, k, which gives corresponding motion to rock shaft h,
which should be connected at p to the steam valve.
Having previously claimed as the Invention the combination of a spring
with the centre of an oscillating bar, I now claim as an improvement upon
that principle the transverse fixture on the same centre of two oscillating
loaded bars acting in resistance to a spring, as described within.
In witness whereof, I, the said George Taylor, have hereunto set my
hand and seal, this First day of August, in the year of our Lord
One thousand eight hundred and fifty-five.
GEORGE TAYLOR. (L.B.)
Witness to the signature of George Taylor,

of 27, Myrtle Street, Liverpool,
