I JOHN RICHARDSON of the firm Robey & Co of Lincoln; in the county of
Lincoln, Engineers do hereby declare the nature of this invention to be as
follows
This invention is for an improvement in the construction of governors for steam
engines, which governors are used either for opening and closing a throttle valve
or for regulating the position of a die in a slot link and so controlling the action of
the cut off valve of an expansion gear.
L
For the purpose of this invention the governor is hung on a sleeve, the centres
being at a distance from a spindle which has no vertical motion.
The driving, of the governor is through a cross head of the spindle and-the
method of adjusting the tension of the spring is by means of one or more turned
nuts on the upper end of the spindle which nuts fit in and serve as guides to
the sleeve.
A governor containing some of the features of the present one has been used for
many years, viz. one in which the balls are suspended at points distant from the
centre and their centrifugal action resisted by a coiled spring within a sleeve but
in such cases the sleeve was fixed so far as its vertical motion was concerned and
it was the part driven. The governor actuated the throttle valve by giving a
vertical motion to the spindle.
In the present invention the spindle is the driver and communicates its motion
to the sleeve which carries the balls through a cross piece on which the short arms
of the ball levers rest.
.
The spindle has no vertical motion so that when the balls fly out the entire
sleeve is raised and through a collar, motion is communicated to the gear worked
by it.
In order to regulate or change the speed of the engine controlled by the governor
a round nut fits the bore of the sleeve and thus serve as a guide for the sleeve at
its upper end.

I, JOHN RICHARDSON of the firm Robey & Co, of Lincoln, in the County of
Lincoln, Engineers, 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:-
This invention is for an improvement in the construction of Governors for
Steam Engines, which Governors, are used either for opening and closing a throttle
valve, or for regulating the position of a die in a slot link, and so controlling the
action of the cut off valve of the expansion gear of a Steam Engine.
For the purpose of this invention, the Governor balls are hung on a sleeve, the
centres being at a distance from a spindle, which has no vertical motion. The
driving of the Governor is effected through a cross head of the spindle, and the
method of adjusting the tension of the spring, is by means of one, or more turned
nuts on the upper end of the spindle, which nuts fit in, and serve as a guide to
the sleeve.
A Governor containing some of the features of the present one, has been used.
for many years, viz: one in which the balls are suspended at points distant from
the centre, and their centrifugal action resisted by a coiled spring within a sleeve,
but in such cases the sleeve was fixed so far as its vertical motion was concerned,
and was the part driven; the Governor actuated the valve by giving a vertical
motion to the spindle.
The manner of carrying the present invention into effect, will be understood by
reference to the annexed drawings. A is the central spindle, which forms the
driver, and is caused to rotate through the bevil wheels B, C, by the engine.
The motion of the spindle A is communicated to the sleeve D, (which carries the
balls E, E) through a cross head, or piece F, on which the arms G, G, of the ball
levers H, H, rest. The spindle A has no vertical motion, but the sleeve D can
move up, and down, upon the said spindle A, and when the balls fly out, the
entire sleeve D is raised, and through a collar I and levers J, K, L, motion is
communicated to a die M in the link N, (said link N being suspended at P to the
supporting frame Q) and by this means to the cut off of the expansion gear.
The centrifugal action of the balls E, E, raises the sleeve, and this action is
resisted by a coiled spring R within the sleeve D. In order to regulate, or change
the speed of the engine controlled by the Governor, one, or more, round nuts S, S,
are provided and turned of such diameter, as to fit the bore of the sleeve D, and
thus serve as a guide for the sleeve D at its upper.end.
It is obvious that the collar I may be used to communicate motion to, and work
gear, of any type which can be worked by other forms of Governor.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what
I claim is:
1. The construction of a Governor, in which the balls are suspended at points
distant from the centre, upon a sleeve capable of vertical motion on a fixed driving

page_text: spindle, and their centrifugal action resisted by a coiled spring, substantially as
described and shown.
2. In a Steam Engine Governor, the employment of a cross head for com-
municating motion, for the purpose of driving the said Governor, as hereinbefore
described and shown.
3. The method of adjusting the tension of the spring by means of one, or more
turned nuts, which nuts, fit in, and serve as guides to the sleeve, as hereinbefore
described for the purpose set forth.
