PROVISIONAL SPECIFICATION.
Improvements in Governors and their Appendages.
JOHN NUTTALL, Engineer No. 10 Hope Street Oldham do hereby declare the
nature of this invention to be as follows
One part of these improvements cousists in constructing the governor arms in a
peculiar manner. These arms are suspended at some point in their length, so as to
form double ended levers. The weighted ends of the arms are placed above the
point of suspension. The other ends are placed below the point of suspension and
are constructed so as to admit of a dead weight being placed upon them. This
dead weight is by preference made in the form of a hollow ball, or globe, and is
arranged so as to enclose the before mentioned governor arms. On the inside of
the ball, or globe are projecting pins or studs, which rest upon the governor arms.
The ball, or globe therefore rises or falls according to the vibrations of the governor
arms. On the lower part of the ball, or globe is a boss this boss has a groove in it,
in which a fork is placed, that transmits the globes motion to the equilibrium
valve by means of a sliding spindle and arm.
In order to make the governors more sensitive, a lever is attached to this arm in
such a manner that whilst one end swings upon a fixed stud, the other end actuates
the equilibrium valve with increased travel or movement. When the equilibrium
valve is placed at some distance from the governors, this lewer may be placed on
one of the levers that connects the governors with the equilibrium valve.

COMPLETE SPECIFICATION.
Improvements in Governors and their Appendages.
JOHN NUTTALL, Engineer No. 10 Hope Street, Oldham Lancashire 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 :-
One part of these improvements, consists in constructing the governor arms in a
peculiar manner. These governor arms are suspended at some point in their length,
so as to form double ended levers.
By reference to the accompanying drawings, in which similar letters represent
like parts in all the figures, it will be seen, that the arms, or levers, may be
arranged in two ways.
In Figs. 1. 2. 3. and 4 the arms are shown suspended in a slot, (D), in the
governor spindle E. This arrangement I prefer for small governors. But for
large governors I prefer the (double) arrangement of arms outside the governor
spindle E Fig. 7.
The arms or levers A and A 1 are weighted at the ends a and a 1. The weighted
ends a and 1, are placed above the point of suspension B, Figs. 1. 2. 3 and 4.
The other ends of the arms A. and A 1 are placed below the point of suspension B
and are constructed with bosses b and 1 on them, Figs. 2. 3 and 4. Or they may
be made to carry rollers e and 1 on pins or studs and 1 Figs. 1 and 7 so as to
allow, or admit of a dead weight being placed upon thein.
This dead weight may be of any suitable form, but is by preference made in the
5 Price 8d1

page_text: form of a 'hollow ball or globe G Figs. 1. 2. 3 and 4, and is arranged so as to
enclose the before mentioned governor arms A. and A. 1. The ball or globe G is
made in two parts.
On the inside of the ball or globe Gare projections, which may either be cast on
the ball or globe, or be made in the form of pins or studs F and F 1, Figs. 1. 2
and 3.
These projecting pins or studs F and F 1 rest upon the governor arms A and A 1,
by means of the bosses band 1, Figs. 2, 3 and 4 or by means of the rollers cand c 1,
Fi gs. 1 and 7.
The ball or globe G therefore rises or falls according to the vibrations of the
governor arms A and A. 1.
On the lower part of the ball or globe G there is a projecting boss H, Figs. 1. 2
and 4.
The boss H has a groove S, in it Figs. 1. 2 and 4 in which a forked arm K Fig. 1
is placed that transmits the globes motion to the sliding spindle g Fig. 1. The
sliding spindle is connected to the equilibrium valve by means of the arm K and
the valve spindle v 1, Fig. 1.
In order to make the governors more sensitive a lever y, Figs. 5 and 6 may be
or is connected to the sliding spindle q by means of the projecting arm R 1 Figs. 5
and 6. The arm R 1 has a pin or stud n, on it, on which the levery swings. This
lever y also swings or vibrates on a fixed stud or pin m in the stand or link,
Figs. 5 and 6, I prefer to make this stand in the form of a flat spring, so that it
will give way to the varying positions of the pin n in its travel or moveinent.
At the point in the lever y, it has the same amount of travel, or movement as
the ball or globe G has. But at the point where the valve spindle y 1 Figs. 5 and 6
passes through the swinging lever y it moves with increased travel and speed, and
therefore opens or closes the equilibrium valve v much quicker than the first named
arrangement in Fig. 1.
When the equilibrium valve is placed at some distance from the governors the
swinging levery Figs. 5. 6. 8 and 9 may be placed on one of the levers that
connects the governors with the equilibrium valve.
In Figs. 8 and 9 the swinging levery is suspended on a stud or pin n in the
lever R 2. The lever R2 swings or vibrates on the pin W, in the fixed stand or
pillar on the valve cover Z. The other parts being the same as Figs. 5
and 6 (before described). The same description will therefore apply to both sets
of figures, excepting that the governors in Figs. 8 and 9 are connected to the
lever R 2 at the point p 1.
Fig. 7. is a plan of the governor arms when placed outside the governor spindle E.
One pair of arms A. are shown in ink lines. The other pair of arms A. 1 are shown
in dotted lines. The arms are shown in this manner so that their relative position
on the governor spindle E may be more clearly understood.
In Fig. 1 I have shown a section of the equilibrium valve v. from which it will
be seen that the valve closes upwards. I do not claim this arrangement of valve
neither do I claim the arrangements for driving the governors.
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
No. 1. The peculiar construction and arrangement of the governor arms A and A 1,
substantially as herein before described and illustrated in the accompanying
drawings.
No. 2. The arrangement of a swinging lever, in combination with a sliding rod,
arm, and fixed stud or pin, in a stand link or other equivalent, substantially as and
for the purpose herein before described, and illustrated in the accompanying
drawings.
No. 3. The arrangement of a swinging lever in combination with another lever

page_text: that swings or vibrates by the governors action or motion, substantially as and for
the purpose
herein before described and illustrated in the accompanying
drawings.
