IMPROVEMENTS IN MACHINERY OR APPARATUS FOR GOVERNING OR REGU- LATING THE SPEED OF STEAM ENGINES OR OTHER MOTIVE POWER
Year: 1861

page_text: LETTERS PATENT to Thomas Haworth, of Nut Mill, Bacup, in tho
County of Lancaster, Spinner and Manufacturer, for the Invention of
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR GOVERNING OR REGU-
LATING THE SPEED OF STEAM ENGINES OR OTHER MOTIVE POWER."
Sealed the 23rd July 1861, and dated the 24th January 1861.
PROVISIONAL SPECIFICATION left by the said Thomas Haworth at the
Office of the Commissioners of Patents, with his Petition, on the
24th January 1861.
I, THOMAS HAWORTH, of Nut Mill, Bacup, in the County of Lancaster,
Spinner and Manufacturer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR GOVERNING OR REGULA-
TING THE SPEED OF STEAK ENGINES OR OTHER MOTIVE POWER," to be as
follows:-
In addition to the ordinary pair of governor balls, which as they revolve
expand and contract, and thus regulate the opening and closing of the valve
to cause the necessary regularity of the working of the engine or other motive
power, I fix ou the same spindle an additional pair of governor balls with the
necessary levers and apparatus in connection therewith, by which I gain a
double regulating power, and secure a more certain regularity of speed than
has been hitherto obtained.

by the said Thomas Haworth in the Great Seal Patent Office on the
23rd July 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
HAWORTH, of Nut Mill, Bacup, in the County of Lancaster, Spinner and
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of January, in the year of our
Lord One thousand eight hundred and sixty-one, in the twenty-fourth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, tho said Thomas Haworth, Her special licence that I, the said
Thomas Haworth, my executors, administrators, and assigns, or such others
as I, the said Thomas Haworth, 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 Inven-
tion for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR GOVERNING OR REGU-
LATING THE SPEED OF STEAM ENGINES OR OTHER MOTIVE POWER," upon the
condition (amongst others) that I, the said Thomas Haworth, my executors
or administrators, by an instrument in writing under my, 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 per-
formed, 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 Thomas Haworth, 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 (that is to say):-
In addition to the ordinary pair of governor arms and balls, which, as they
revolve, expand and contract according to their speed, and thus regulate the
opening or closing of the valve to cause the necessary regularity of the working
of the engine or other motive power, I joint on the ordinary governor spindle
an additional pair of arms and balls, with the necessary levers and apparatus
in connection therewith, by which 1 gain a double regulating power, and
secure a more certain regularity of speed than has been hitherto obtained.

page_text: These improvements will be clearly understood by referring to the Figures
and letters on the accompanying Sheet of Drawings.
In Figs. 1 and 2, a is the ordinary governor spindle; b, the ordinary
governor arms and balls; and c, the supplementary governor balls and arms,
which, in Fig. 1, are shewn below the others, the better to shew their mode of
action. In Fig. 1, d, e, is the governor rod, in connection with the ordinary
arms and balls;, the tube attached to the supplementary arms and balls,
which tube and rod pass through the interior of the governor spindle; g is a
universal joint or socket coupling, having set screws, which coupling is for the
purpose of connecting together the lower part d of the governor rod and
the upper part e, in such manner that when the lower part turns the upper
part may move independently of the lower part; h is a balance weight acting
on the governor balls, and balancing the throttle valve and parts connected
with it; are moveable weights, of which more or less can be used as
required, in order to exert a greater or less pressure upon the supplementary
arms and balls, and adjust the speed of the engine as may be found necessary;
is the coupling-up rod to the throttle valve; is a small spur driving wheel
on the top of the tube f, and revolving with it. The upper part d of the
governor rod screws into the boss m, which can be shifted to the check nuts n,
or otherwise; the rod e bas in it n key, which slides up and down in the slot
of a loose bush, and on the bush is a flange for supporting the toothed wheel o,
and on the outside of the flange is a notch, which is acted upon by a catch and
spring on the wheel o. The wheel o gears on one side into the wheel p on
the top of the shaft q, at the bottom of which is the wheel r, and on the other
side the wheel gears into the broad pinion s, which also gears into the
wheel t on the shaft u, at the bottom of which is the wheel v. The wheels
and v are at different levels, but at such distances from the centre of the
governor spindle that they may gear with the wheel when it is raised or
lowered. There is sufficient space between the two wheels r, v, for the
driving wheel to turn without gearing with either wheel, and when it does so
the engine is working at its proper speed, but if the speed should decrease, all
the governor balls will descend, and the descent of the supplementary balls
and arms will bring down the wheel so as to gear in the wheel and turn
the shaft u and wheel t which turns the broad pinion s, the wheel o, and also
the upper rod e, and if the motion is continued the boss m will be brought
down to the check nuts n, by which means the rode will be brought down
lower than it would be by the action of the ordinary governor balls only, and
the rod and boss will become stationary, the action of the catch and spring
ว

be sufficient steam and speed to relieve it and raise the wheel out of gear
with the wheel v. When the engine is turning too quickly, the wheel / will
gear into the wheel r, which turns the wheel p gearing into the wheel o,
which is thus turned in a contrary direction, and by means of the screw raises
the boss m, and proportionately closes the throttle valve. Instead of using
spur wheels for turning the rod e, friction pulleys may be employed for the
same purpose, as shewn in Figures 8 and 4.
Having now described the nature and particulars of my said Invention,
and the manner in which the same is to be performed, I desire it to be
understood that I claim as my Invention, and which, to the best of my
knowledge and belief has not been hitherto used within the realm, the
addition to the ordinary pair of governor arms and balls of another pair of
governor arms and balls, with the necessary levers and apparatus connected
therewith, for the purpose of obtaining a double regulating power, and securing
an uniform speed of the steam engine or other motivo power, as all such
improvements are herein described and illustrated in the accompanying Sheet
of Drawings.
In witness whereof, I, the said Thomas Haworth, have hereunto set
my hand and seal, this Twenty-second day of July, in the year of our
Lord One thousand eight hundred and sixty-one.
THOMAS HAWORTH. (L.S.)

within-named Thomas Haworth,
