PROVISIONAL SPECIFICATION.
Improvements in or connected with the Governors of Steam and
other Motive Power Engines.
I, JOSEPH JONES, of Tame Side Mills, Dukinfield, in the County of Chester,
Assistant Manager, do hereby declare the nature of this invention to be as
follows:-
The invention is designed with the object of providing a connection or an
appliance whereby the action of the governor gear as ordinarily used in steam
engines, and other motive power engines is supplemented and a quicker change
effected.
In carrying out the invention I apply a supplementary governor or auxiliary
appliance in the form of a movable balance weight supported on a vertical rod
whereby the movement of change of the governor gear is assisted and facilitated.
A vertical or connecting rod or spindle is keyed or attached to a rocking shaft
which receives and imparts a movement corresponding to that of the rise and fall
of the governor itself.
On the upper end of the vertical rod is fixed a bracket with a specially prepared
surface to receive and provide a path for a bowl or ball to move on. At present I
prefer one bowl or ball but if found desirable two or more may be used either
rolling separately or connected together.
The prepared surface of the bracket upon which the ball or bowl moves is
preferably a curved path. The bowl path or surface is so arranged as to allow it
to move a little in advance of the centre line of the vertical rod thereby adding
weight to that side and consequently assisting the governor in its change of motion
or direction. The action takes place first in one direction and then in the other
at each time the governor is reversed or movement takes place in an opposite
direction.
Instead of the rolling arrangement of the bowl or ball a dead weight may be used
in addition to that sufficient to balance the gearing or a vessel of liquid or other
freely moving body may be employed.
An arrangement can also be applied to bring the vertical rod perpendicular in
case any great alteration in the working load is required.
The several parts are connected together by suitable connections so as to work
together as required.
As a result I gain a steady and more uniform working of the engine it not being
affected by change in steam pressure or other causes of irregular running.

COMPLETE SPECIFICATION.
Improvements in or connected with the Governors of Steam and
other Motive Power Engines.
JOSEPH JONES of Tameside Mills Dukinfield in the County of Chester,
Assistant Manager, do hereby declare the nature of my invention for REGULATING
THE SPEED OF MOTIVE POWER ENGINES, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:—
The invention is designed with the object of providing a connection or appliance
whereby the action of the governor gear as ordinarily used in steam engines and

page_text: those of other motive power, is supplemented and a quicker change effected. Io
carrying out my invention I apply a supplementary governor or auxiliary appliance
in the form of a movable balance weight, supported on a vertical rod whereby the
movement of change of the governor gear is assisted and facilitated. A vertical or
connecting rod or spindle is keyed or attached to a rocking shaft which receives
and imparts an oscillating movement corresponding to that of the rise and fall of
the governor itself.
On the upper end of the vertical rod is fixed a bracket or slipper with a specially
prepared surface to receive and provide a path for, a bowl or ball to move on.
At present I prefer one bowl or ball, but if found necessary two or more may be
used either rolling separately or counected together.
The prepared surface upon which the bowl or ball moves is preferably a curved
path. The bowl path or surface is so arranged as to allow it to move a little in
advance of the centre line of the vertical rod thereby adding (through torsion set
up in the supporting shaft) weight to that side and consequently assisting the
governor in its change of motion or direction. The action takes place first in one
direction and then in the other at each time the governor is reversed or movement
takes place in an opposite direction.
A second rod or pendulum is introduced, hanging loose upon the rocking shaft,
having near its lower extremity a balance weight. The function of this arrange-
ment is to regulate the range of movement of the upper rod.
The several parts are suitably connected so that they will work together as
required.
The invention will be fully described by the aid of the accompanying drawings,
which show sufficient of the engine to make clear and illustrate the invention.
Figure 1. is a front elevation.
Figure 2. is a side elevation.
Figure 3. is a plan.
The rocking shaft or spindle A is connected to the governor by a rod or as
shown in Figs. 2 and 3 by the forked lever K, or other means so that any movement
in the governor is followed by an oscillation of A.
Fastened on the shaft A is a bracket J, the upper portion of this bracket carries
a screw I with millheaded hand wheels H; on the screw is a combined nut and
filboe M, one part of which is bored at right angles to the nut to allow the rod B
to pass through either these parts or their equivalents may be used to support the
rod B to hold it in the desired position on A. The object being to facilitate the
setting of the apparatus as required.
Fixed on the rod B at its upper end is a curved trough or slipper C, in which a
loose roller (or rollers) D is sustained. In speaking of the upper end of the rod D
it will be henceforth understood to mean at a point shown cut by the line X, being
the level of that part of D which is in contact with C, and is the lowest point in
the curve portion of the latter, spoken of as a specially prepared surface, when B is
perpendicular.
The end of the rod B describes with A as its centre the arc Z, this represents
the path C will follow bodily; if D were also permitted to follow this path, it is
clear that on B leaving the vertical position the torsion 'imparted to A would assist
the governor, but on the reverse movement taking place there would follow a
retarding influence. To overcome this I arrange the roller D so that it maintains
a horizontal position and travels along the path of X. To effect this the arc Y of
the slipper C is formed to a corresponding arc of an opposing circle to that
described already as Z.
Thus this arrangement permits a rapid and easy transition of free weight from
one position to another D being that weight, which on receiving a tilt arising
from an oscillating movement in A, runs in advance of the vertical centre line of B,
and thereby gives additional torsion in the direction. of movement, and, until the
true position is again found on the governor coming to rest in its new position to
suit the varying load.

page_text: It must be understood that the vertical position is the true one of B, when the
plane of the governor balls in revolution correspond with that of the normal speed
of the engine.
In effect my invention when in action suitably moves the centre weight or
counterpoise of the governor, by this means a uniform rate of engine speed is.
secured. Such work is usually performed by an increase or decrease in the speed
of engine, altering proportionally the rotation of the plane of the governor balls
as required for either a greater or less admission of steam to the cylinders.
In order to balance the weight of the rod B and its attachments, and prevent
"hunting," that is running extremes either fast or slow, I apply a second rod E.
with a balance weight W at its lower end.
This rod or pendulum hangs loose upon the shaft A, and is slotted at N, Fig. 1.
It is also provided with two set screws Ġ pointing into the slot N.
The boss of the rod B has on its lower part a projecting tail piece and stud F,
which latter moves freely in the slot N formed in E. The order of this arrange-.
ment may be reversed; the slot formed in B and stud in E if prefered, either
above or below the shaft A in either case.
The range of movement of B permitted is regulated by the adjusting screws G,
which latter can be set as desired. Thus the pendulum E being loose upon the
shaft A is not brought into contact with the screws G, nor does it exert any
influence on the rod B until a certain range of movement of B has taken place,.
after which the whole apparatus is practically in a state of equilibrium, during the
period of such conditions.
For illustration, the dotted lines B' and B' in Fig. 1, show an assumed position
or range of movement B may be allowed before the lower rod E be moved from its
natural position; which only occurs after contact is made between F and G.
Fig. 3 shows clearly how the invention may be applied to a steam engine of
ordinary build, the dies L, work in a groove or socket or other equivalent of the
governor gear used to give effect to the steam valve compensating for any
irregularity taking place.
I do not illustrate any portion of the arrangement beyond the dies or their
equivalents, such being well known and not necessary for my purpose. The
dies L, L are held in place by a forked lever K or other means, and keyed or
otherwise suitably fastened to the rocking or other such shaft as A, to which
usually are attached the levers or other mechanism employed to operate the valve
or valves.
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 I
claim is.
1. In connection with governors or other devices for regulating the speed of
steam or other motive power engines: means substantially as hereinbefore
described, whereby the speed of the engine is more uniformly governed.
2. In combination with a governor or regulating device and a valve or valves
operated thereby of a free or rolling weight (or weights) or its equivalent supported
at the end of a rod, attached in such a position that it exercises with every rise
and fall of the governor, a torsional influence substantially as hereinbefore
described.
3. In combination with above parts or other regulating device, a weighted
pendulum used for such purposes substantially as hereinbefore described.
4. The arrangements hereinbefore described and shown in Figs. 1. 2. 3 of the
accompanying drawings.
