PROVISIONAL SPECIFICATION.
Improved Means of Governing or Regulating the Speed of Steam or
other Motive Power Engines.
We, LUKE RUSHWORTH, of 218 Edge Lane, Droylsden, in the County of
Lancaster, Mechanic, and ISAAC MOORHOUSE LIVSEY, of 94 Margaret Street
North, Ashton-under-Lyne in the County of Lancaster, Engineer, do hereby
declare the nature of this invention to be as follows:-
The arrangement consists of a suitable stand and pillar, to receive the spindle
and its attachments, driven and revolving in the usual manner.
The main spindle is partly a tube, and has a fulcrum which is the point of
suspension, situated outside the centre of rotation, attached to and through
this fulcrum centre, is a tubular pendulum extending across the centre of rotation.
This tubular pendulum has a piston attached thereto, with a cylinder which
encloses the piston, and slides thereon, this moving cylinder is connected by a rod
or rods to a spring, and controlled thereby in its movement on the said piston and
pendulum and, thereby gives a variable length of pendulum as required.
This tubular pendulum at or about the centre of rotation, is connected to a
piston inside the main tubular spindle, and through this connection the motions
of the pendulum are transmitted to a slide with toothed catches attached
thereto.
This slide and its catches, are contained in another slide, which moves at
right angles and receives its motion from an inclined toothed plate which is
actuated by an eccentric or crank.
The slide with its toothed catches engaging on either side of the inclined
toothed plate is actuated thereby, and in proportion to the position or point of
contact of the catches with the inclined toothed plate, the variable position of
the slide with its catches, is transmitted and connected to the throttle valve or
cut off gear of the engine.

COMPLETE SPECIFICATION.
Improved Means of Governing or Regulating the Speed of Steam or
other Motive Power Engines.
We, LUKE RUSHWORTH, of 218 Edge Lane, Droylsden, in the County of
Lancaster, Mechanic, and ISAAC MOORHOUSE LIVSEY, of 94 Margaret Street
North, Ashton-under-Lyne, in the County of Lancaster, 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 :-
Our invention for governing or regulating the speed of steam or other motive
power engines, consists of a suitable stand and pillar, to receive the main spindle
and its various attachments or parts, which spindle is driven or caused to revolve
in the usual manner.
The manner in which our invention is to be performed or carried into practical
effect, will be readily understood on reference to the two sheets of drawings
hereunto annexed and the following explanation thereof.
Fig. 1 or Sheet 1. is an elevation and Fig. 2 on Sheet 1. is a sectional elevation
of the governor.

page_text: Fig. 3. on Sheet 2. is an elevation, and Fig. 4. on Sheet 2. is a plan of the
governor stand, with the connection to the inclined toothed plate or bar, and the
compound slide with its catches.
Referring to Figs. 1 and 2 on Sheet 1. A is the top portion of the governor
pillar.
The main spindle B is partly a tube, and has a fulcrum C which is the point of
suspension situated outside the centre of rotation, attached to and through this
fulcrum centre C is a tubular pendulum D extending across the centre of
rotation.
This tubular pendulum D has a piston attached thereto at or near its lower
extremity, with a cylinder F which encloses the piston E and slides thereon,
this moving cylinder F is connected by one or more rods G to a spiral spring H
at the top end of which is a nut and screw adjustment for regulating the movements
of the cylinder F which is filled with a liquid of the consistency required, and is
controlled thereby in the passing of the liquid from one side to the other side of
the piston E thus giving an automatically lengthening and shortening pendulum, as
the altering conditions of load on the engine may require.
The tubular pendulum D at or near the centre of rotation forms a connection by
the pivot bar I with a dash pot piston J. situated and working inside the lower end
of the main tubular spindle, B.
Through and by this connection either from the upper end K at J X of the
dash pot piston connection or from the collar and lever attachment L formed on
the lower end of the counterpoise weight M which works on the main tubular
spindle B the motions and variations of the pendulum are transmitted to a slide N
as shewn on Figs. 3 and 4 of Sheet 2. This slide N and its toothed catches O, O,
are contained and move in another slide, P which moves at right angles to the
slide N and receives its motions from the inclined toothed plate or bar Q
which is worked by the eccentric R or may be worked by a crank or other
suitable motion.
The slide N with its toothed catches O, O, engaging on either side of the
inclined toothed plate or bar Q is thereby actuated in the length of its forward
or backward motion or position, and in proportion to the positions at the
different points of contact of the catches O, O, with the inclined toothed plate
or bar Q.
The variations in its position resulting from the changes of load on the engine
are transmitted through or by the spindle or bar S to the throttle valve or cut off
gear of the engine or prime mover, and thereby giving a constant speed or good
governing.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. The tubular pendulum with a cylindrical ball, which automatically length s
and shortens, and is tuned or regulated by means of a screw adjustment in co-
bination with a rod and spring, and controlled in its movements by a liquid
contained in the cylindrical ball.
2. The connection formed between the pendulum and the combined inter al
spindle and dash pot by means of a pivot bar.
3. The compound slide with its toothed catches, and the inclined toothed plate
or bar with which the said catches engage all substantially as herein before described
and illustrated by the drawings annexed.
Dated this 27th day of August 1891.
