PROVISIONAL SPECIFICATION.
Improvements in Mechanism or Arrangements for Governing the
Speed of Steam or other Motive Engines..
I JOSEPH HIGGINSON Junior of 90 Henry Street, Ancoats in the City of Manchester
in the County of Lancaster, Mill Manager, do hereby declare the nature of the said
invention, to be as follows:-
My invention has the same object as that described in the specification recorded
by me with application for a Patent Numbered 2986 A.D. 1888, and relates to a
modification or to modifications of the invention described in the said specification
wherein two vessels are described carried on opposite ends of a beam lever, partly
filled with any suitable weighting fluid, (mercury being preferred) which fluid in
the vessels being oscillated by connection with the centrifugal governor will pass from
one vessel to the other and increase or decrease the load upon it, as required, and thus
make the governor isochronous, as explained in my said specification.
My present invention consists in the application of two vessels each to be partly
filled with a suitable weighting fluid but only one lever is used which carries one
vessel at its extreme end and the other vessel is placed at or near the fulcrum of the
said arm or lever and is either attached to the arm at the fulcrum or to a part from
the fulcrum, or this vessel is stationary at or near the fulcrum (by preference) of the
arm or lever carrying the other vessel.
The two vessels are made to communicate by a tube or passago so that the fluid will
flow from one vessel to the other as the arm or lever is oscillated by the movements of
the governor.
When the arm or lever is in the level position the two vessels viz. that on the arm
or lever at or near its end and that at or near its fulcrum are equally filled with the
weighting fluid, but when the vessel on the end of the arm ascends the fluid flows
from it to the vessel near its fulcrum, and when the arm or lever descends below the
level position, the fluid flows from the vessel near the fulcrum of the arm to the vessel
at or near the end of the arm or lever.
When both vessels are attached to the arm or lever, one being near the fulcrum,
and both on the same side of the fulcrum of the arm or lever, they are or may be
connected by a rigid tube having a cock or valve to regulate the flow of the weighting
fluid from one vessel to the other, and when one vessel is stationary the two vessels
are or may be connected by a flexible tube or syphon arrangement or a swivel
jointed pipe.
Filling in pieces are or may be used to adjust the capacity of the vessels to the
requirements of each governor to make it isochronous.

Improvements in Mechanism or Arrangements for Governing the
Speed of Steam or other Motive Engines.
I, JOSEPH HIGGINSON Junior, late of 90 Henry Street, now of, 20 Canal Street,
Ancoats, in the City of Manchester, in the County of Lancaster, late Mill Manager
now Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention has the same object as that described in the. Complete Specification

page_text: of a Patent Numbered 2986 A.D. 1888 and relates to a modification or to modifica
tions of the invention described in the said specification wherein two vessels, are
described, carried on opposite ends of a beam lever, partly filled with any suitable
weighting fluid, (mercury being preferred) which fluid in the vessels being oscillated
by connection with the centrifugal governor, will pass from one vessel to the other
and increase or decrease the load upon it as required, and thus make the governor
isochronous, as explained in my said specification.
My present invention is applicable in some cases where my former invention cannot
be so conveniently used and consists in the application of two vessels, each to be
partly filled with a suitable weighting fluid but only one lever is used which carries
ono vessel at its extreme end and the other vessel is placed at or near the fulcrum of
the said arm or lever and is either attached to the arm at the fulcrum or to a part
attached to and near the fulcrum, or this vessel is stationary, at or near the
fulcrum by preference, of the arm or lever carrying the other vessel.
The two vessels are made to communicate by a tube or passago so that the fluid
will flow from one vessel to the other as the arin or lover is oscillated by the move-
ments of the governor.
When the arm or lever is in the level position the two vossels viz., that on the arm
or lever at or near its end and that at or near its fulcrum are equally filled with the
weighting fluid, but when the vessel on the end of the arm ascends, the fluid flows
from it to the vessel near its fulcrum, and when the arm or lever descends below the
level position, the fluid flows from the vessel near the fulcrum of the arm to the
vessel at or near the end of the arm or lever.
•
When both vessels are attached to the arm or lever, one being near the fulcrum,
and both on the same side of the fulcrum of the arm or lever, tliey are or may be
connected by a rigid tube having a cock or valve to regulate the flow of the weighting
fluid from one vessel to the other, and when one vessel is stationary the two vessels
are or may be connected by a flexible tube or syphon arrangement' or a swivel
jointed pipe.
a
Filling in pieces are or may be used to adjust the capacity of the vessels to the
requirements of each governor to make it isochronous.
Figs. 1' and 2 are sectional elevations illustrating two modifications of any invention
in which only one arm or lever i is used 'and which carries one vessel (j) to contain
the weighting fluid on or near its end, another vessel (') being used to receive the
weighting fluid from and return it to the vessel j, on the arm or lever 'accordingly as
the latter oscillates up or down.
The vessel, is by preference carried on the fulcrum or shaft: g, for the lever or
arm i, but may be carried on the arm or lever near its fulcrum g.
In the modifications shown by figs. 1 and 2' the vessels, and j; are of larger
capacity than when two vessels are used each on an arm on opposite sides of the
fulcrum or shaft g, as described in my aforesaid specification.
In fig. 1, g, is the fulcrum or shaft oscillated by the governor'; 1, is a part secured
to it to which the vessel j¹, is screwed. i, is an arm screwed into the part';
which has another part, secured to it.by, a. set screw to which the vessel j, is
screwed.
Each part, and, forms a plug to close the upper end of each vessel j', and j, and
in each plug there is a small hole, for air to enter and leave the vessels.
1
The lower ends of the two vessels, and, are connected by a tube m, having a
tap., by which the flow of the weighting liquid from one vessel to the other is
regulated.
Each vessel is filled about half full' of the weighting fluid,. (mercury by
preference).
Parallel or taper pieces of wood. k; may be used as explained' in my aforesaid'
specification for adjusting the capacity of the vessels to the governor.

The modification shown by. fig. 2 is similar to that shown by fig. 1, except that both 5
vessels, and, are closed by plugs, air tight; the air holes ; (shown in fig. 1)
being dispensed with, and two tubes m, and, are used, one tube m, connecting, the

page_text: lower, and the other. tube i*, the upper parts of the two vessels ;, and j'.-The
tap 1, being used to regulate the flow of air, and thus the weighting fluid from.one
vessel to the other...
The screws m³, screw into holes in bosses upon the vessel j, to press a collar on
the end of each pipe i*, and m, against the bottom of the hole in the boss, thus
making the pipes fluid tight, and securing the vessels j, to the ends of the tubes i*,
and m, but any other mode of. attachment may be employed.
g, is the axis oscillated by the governor which enters a hole in a. boss. formed on
one side of the vessel j¹, being secured thereto by a set screw.
Figs. 3, 4 and 5 illustrate other modifications of my invention, in which the vessel'',
is not mounted. on the fulcrum of the shaft g, but is stationary and is secured say by
a bolt at a, to any suitable and convenient stationary part or carrier.
This vessel j', in fig. 3 is placed by preference to come opposite the end of the
shaft 9, which is oscillated by the governor.
This shaft g,,has a boss part i¹, secured to it by a set screw, in which one end of an
arm i, is screwed the other end being screwed into a boss formed on the vessel j, which
consequently oscillates with the governor..
The upper and lower ends of the vessels j, and, are connected as described in
reference to fig. 2 except that in this case indin rubber tubes ix, and m, are used, the
ends of which pass over and are bound by wire, to short metal tubes projecting
from the bosses on the vessels j, and j¹.
In the middle or level position of the vessel j, the india rubber tubes are shown
extended to their greatest length and as the vessel j, rises above or falls below the
middle or level position, the india rubber tubes bend a little.
In fig. 4, the vessel j, is mounted on an arm i, from the boss ¹, on the end of the
shaft g, as described in reference to fig. 3, and the vessel j³, is also placed and carried
as described in reference to fig. 3, and the two vessels are connected by swivel
jointed pipes m, as shown, these jointed pipes allowing the vessel ;, to move up and
down while the vessel j¹, remains stationary.
1, is the regulating tap.
Fig. 5 illustrates another modification similar to fig. 4, except that a syphon pipe
is used to connect the two vessels.
One leg of this syphon pipe n, is inserted through the plug i, at the upper end of
the vessel, which has a small hole ³, for air.
The syphon pipe n, has also a tap 1, to regulate the flow of weighting fluid from
one vessel to the other-That leg of the syphon pipe n, in the fixed vessel j¹, oscillates
in it with the movements of the vessel j.
The vessels, and j', may be partly filled with the weighting fluid part of which
may be drawn into the syphon pipe n, to fill it, through a short branch n¹³, having a
small lifting valve fitted into it opening outwards.
On this branch n', the mouth of an india rubber bag p, is placed, then the bag is
compressed to expel the air from it, and then it is allowed to expand when the
weighting fluid will fill the syphon pipe and a little may pass through the lifting
valve which will close against its return, and into the india rubber bag, which may
then be removed, the surplus liquid being caught in a cup or other vessel.
Then a cap n³, may be screwed upon the branch n¹, to keep the small lifting valve
closed.
Taper or parallel adjusting pieces k, may be used if desired in the modifications
shown by figs. 1, 2, 3 and 4.
In carrying out my invention I prefer to use the modifications illustrated by figs. 1'
and 2, as the most, simple and least expensive.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
claim is.
1. The combination of two vessels partly filled with a suitable fluid, mercury by
preference, one vessel at or near one end of a lever oscillated by connection with a

page_text: centrifugal governor the other vessel at or near the fulcrum of the lever either
mounted or carried upon the fulcrum of the lever or carried on a suitable support
near the fulcrum of the lever, the two vessels communicating with each other by a
suitable pipe or passage or pipes or passages to allow the fluid to flow from one vessel
to the other substantially as and for the purpose herein before described and illustrated
by figs. 1 and 2 of the drawings.
2. The combination of two vessels (; and j³) arranged and acting substantially as
and for the purpose herein before described and illustrated by figs. 1 and 2 and
figs. 3, 4 and 5.
3. Adjusting the sectional areas of both vessels (j, and j¹) or the one carried at or
near the end of the arm substantially as hereinbefore referred to and as illustrated by
figs. 1 and 2 of the drawings.
Dated this Ninth day of July 1889.
