IMPROVEMENTS IN GOVERNORS FOR MOTIVE-POWER ENGINES
Year: 1872

page_text: LETTERS PATENT to William Glover, of St. James' Road, Old Kent
Road, in the County of Surrey, and Henry Sykes, of Bankside, in
the Borough of Southwark, for the Invention of "IMPROVEMENTS IN
GOVERNORS FOR MOTIVE-POWER ENGINES.”
Sealed the 5th November 1872, and dated the 10th May 1872.
PROVISIONAL SPECIFICATION left by the said William Glover and
Henry Sykes at the Office of the Commissioners of Patents, with
their Petition, on the 10th May 1872.
We, WILLIAM GLOVER, of St. James' Road, Old Kent Road, in the
County of Surrey, and HENRY SYKES, of Bankside, in the Borough
of Southwark, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN GOVERNORS FOR MOTIVE-POWER ENGINES," to be as
follows:-
Our Invention consists of a novel construction of governor, which by
acting through the intervention of a lever or other equivalent device on
the throttle valve or other suitable valve of the engine will regulate the
speed of the engine in the same manner as ordinary steam engine
governors.

page_text: Our improved governor consists of a horizontal metal cup (with
inclined sides) mounted on a vertical shaft, which is kept in rapid
rotation by means of a driving band passed round a pulley on the shaft,
and actuated from any convenient part of the engine.
".
-
;
In the horizontal cup are placed two, three, or more iron or other 5
metal balls, which as the shaft and cup rotate at considerable speed will
be driven by centrifugal force up the inclined sides of the cup, and in so
doing will be made to lift or raise up an inverted cup or cover placed
over the rotary cup. The vertical shaft of the governor passes freely
through a cylindrical hole in the inverted cup or cover, so that the 1
latter is free to rise and fall on the vertical shaft as the speed of
the shaft varies.
:
A forked lever or other suitable mechanical device takes into a
groove made in the neck of the inverted cup or cover, and is thereby
enabled to act upon the throttle or other valve of the engine, and by 1
regulating the supply of steam will govern the speed of the engine..

SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said William Glover and Henry Sykes in the Great
Seal Patent Office on the 9th November 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM 2
GLOVER, of St. James's Road, Old Kent Road, in the County of Surrey,
and HENRY SYKES, of Bankside, in the Borough of Southwark, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of May, in the year of 2
our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said William Glover and Henry Sykes, Her
special licence that we, the said William Glover and Henry Sykes, our
executors, administrators, and assigns, or such others as we, the said 3
William Glover and Henry Sykes, our 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

page_text: Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "IMPROVEMENTS. IN GOVERNORS FOR MOTIVE-POWER
ENGINES," upon the condition (amongst others) that we, the said
William Glover' and Henry Sykes, our executors or administrators, by
3 an instrument in writing under our, or their, or one of their hands
and seals, 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 William Glover, on behalf of
myself and of the said Henry Sykes,. do hereby declare the nature of our
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) :-
.Our Invention of improvements in governors for motive-power
engines consists of a novel construction of governor, which by acting
through the intervention of a lever or other equivalent device on the
throttle valve or other suitable valve of the engine will regulate the
'speed of the engine in the same manner as ordinary steam engine
governors.
In the accompanying Drawing Fig. 1 is an external elevation of our
improved governor; Fig. 2 is a vertical section of the same; Fig. 3 is
5 a plan view of the bottom cup; and Fig. 4 is an inverted view of
the top cup.
It will be seen that our improved governor consists of a horizontal
metal cup a called the bottom cup; it is made of a dish shape with
curved or inclined sides, and is mounted and keyed on a vertical shaft 6,
which is kept in rapid rotation by means of a driving band passed round
a pulley o on the stem of the cup a. This band is driven and the moving
parts are actuated from any convenient part of the engine. In the
horizontal cup a are placed two or more metal balls d, d, which as the
shaft 6 and cup o a rotate at considerable speed will be driven by centri..
; fugal force up. the inclined sides of the cup, and in so doing will be made.
to lift or raise up an inverted cup or cover e, e, placed over the rotary
cup a.
The vertical shaft 6 of the governor passes freely through..

page_text: a cylindrical hole in the inverted cup or cover e, so that the latter is.
free to rise and fall on the vertical shaft 6 as the speed of the shaft
varies.
Radial feather guides e³, e³, are cast on the under side of the inverted
cup or cover e, and serve to keep the metal balls d, d, in their place on
the bottom cup a. The vertical flange e³, e³, of the inverted cup e os
provided with two feathers e', e³, which are placed diametrically opposite
to one another, and work freely up and down two slots made in the edge
of the bottom cup a, so that all the parts are carried round together with
the vertical shaft b.
A forked lever, or other suitable mechanical device, takes into a
groove made in the neck of the inverted cup or cover, and is thereby
enabled to act upon the throttle or other valve of the engine in the same
way as in other governors, so that by regulating the supply of steam to
the cylinder the speed of the engine will be governed..
As the proper action of this improved governor will not be materially
affected by the occasional divergence of the shaft 6 from the perpen-
dicular it will be found particularly applicable for portable engines, and
especially for marine engines in which the ordinary ball governors will
not work satisfactorily.

Having now described our Invention of "Improvements in Governors
for Motive-power Engines," and having explained the manner of carry-
ing the same into effect, we claim as the Invention secured to us by
Letters Patent as aforesaid, the combination of the upper and lower
cups e and a, and centrifugal balls d, d, with the vertical shaft b, as and 2
for the purpose herein set forth.
Yo
For the purpose merem set forth.
In witness whereof, I, the said William Glover, have hereunto set
hand and seal, the Eighth day of November, in the year of
our Lord One thousand eight hundred and seventy-two.
