PROVISIONAL SPECIFICATION.
Improvements in Marine Engine Governors for Preventing the
Racing of Marine Engines when Propeller is out of the Water.
HENRY ORRELL VAUGHAN,. Crown Chambers, Side, Newcastle-on-Tyne,
Engine Fitter, do hereby declare the nature of this invention to be as follows:-
:-
This invention comprises a cylinder, piston, piston-rod, two valve chambers and
valves, pipes leading from valve chambers to each end of cylinder, pipe connecting
both valve chambers with condenser of main engines, levers for working valves,
and a frame of iron or other metal, within which a ball of iron or other metal is
allowed to roll in a direction fore or aft of the ship.
I arrange these different parts so that when the ball is caused to move forward
or aft by the pitching of a steam ship, it depresses one of the levers, which in turn,
BO arranges one of the valves, that the interior of the cylinder is affected by the
vacuum in the condenser, and the position of the piston of the governor, is altered
accordingly.
As one end of the governor piston-rod is connected with the throttle or other
valve in the steam pipe, leading from the ship's boilers to the engines, and, as
such valve is opened or closed according to the position of the piston-rod
of the governor, it will be seen that the action of the ball cuts off the supply of
steam to the ship's engines when the stern is raised out of the water, and allows
access of steam when the stern falls again.
I adjust the apparatus, including the ball, by an adjusting bracket so that I
obtain the desired result.

COMPLETE SPECIFICATION.
Improvements in Marine Engine Governors for Preventing the
Racing of Marine Engines when Propeller is out of the Water.
HENRY ORRELL VAUGHAN Crown Chambers, Side Newcastle-on-Tyne Engine
Fitter, 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 comprises a cylinder piston, piston-rod, two valve chambers and
valves, pipes leading from valve chambers to each end of cylinder, pipe connecting
both va.ve chambers with condenser of main engines, levers for working valves and
a frame of iron or other metal within which a ball of iron or other metal is allowed
to roll in a direction fore and aft of the ship.
I arrange these different parts so that when the ball is caused to move fore or
aft, by the pitching of a steamship, it depresses one of the levers, which in turn so
arranges one of the valves that the interior of the cylinder is affected by the
vacuum in the condenser and the position of the piston is altered accordingly.
As one end of the governor piston-rod is connected with the throttle or other
valve in the steam pipe leading from the ship's boilers to the engines, and as such
valve is opened or closed according to the position of the piston-rod of the

page_text: governor, it will be seen that the action of the ball cuts off the supply of steam
to the ship's engines as the stern rises, and allows access of steam as the stern
falls again.
I adjust the apparatus including the ball by an adjusting bracket, so that I
obtain the desired result.
I construct my apparatus in accordance with the 4 sheets of drawings accom-
panying this Specification and marked 1. 2. 3 and 4. and to which drawings the
following explanations refer.
A ball marked A in the drawing is enclosed within four equidistant bars B fixed
in a direction fore and aft of the ship in which direction also the ball is free to
move within the bars to the extent of the metal plates to which the bars are
secured.
The ball being thus free to travel by the force of gravitation is weight is, as the
ship's stern rises, brought to bear upon and depress the lever C and as the ship's
stern falls again the weight of the ball is brought to bear upon and depress the
lever I.
The bars are fixed at a slight incline from the horizontal in such a way that
ordinarily the ball rests at the stern end and pressing upon the lever I and thus.
generally keeps the throttle valve open and engines supplied with steam.
As the ball moves from one end to the other of the bars, one or other of valves.E
will be opened, the other valve being kept shut by the force of the coiled spring O
shewn in the drawing.
The chambers of the valves are connected by a pipe P with the condenser of the
main engines, and the action of the valves opens or closes (as the case may be) a
communication with the cylinder G through the pipes F forming a vacuum ou one
side or the other of the piston H (as the case may be) in accordance with the
position of the ball, whether it is depressing the forward lever or the after one.
Thus as the stern of the ship rises the ball gravitates forward and depresses the
levers C and D, the lever D'operating on and opening the forward relief valve K
and admitting the atmosphere to the forward side of the piston, simultaneously, the
after valve E is opened by the raising of the other end of the lever C attached
to the valve spindle E forming a vacuum on the after side of the piston and thus
the piston with its rod is moved to the after end of the cylinder.
It will be seen that when the ball impinges against either of the levers C or I it
does this by pressure in a downward direction thus avoiding the loss by friction
which would be caused if the levers were so arranged that the ball pressed against
them in a more or less horizontal direction.
On the forward end of the piston-rod is a double joint to connect with suitable
rods or levers or other connections with the throttle valve in the steam pipe of the
engines to be governed.
As the stern of the ship falls the ball gravitates aft and depresses the
levers. I and J thus admitting the atmosphere to the after side of the piston and
forming a vacuum on the forward side of the piston, thus the piston is moved to
the forward end of the cylinder by which means the throttle valve is opened for
admission of steam to the engines.
In order to obviate any concussion between the piston and cylinder covers I fit
on the inner side of the covers or on the piston as I. find advisable spiral or other
springs, india rubber discs, as L or any suitable arrangement of buffers to effect
this purpose.
In order to allow the apparatus to work in accordance with the trim of the
vessel I secure it to a plate one end of which is moveable by joints, at the other
end of which I place a screw M for the purpose of elevation or depression.
The joints and screw M are in turn secured to a suitable bracket to be fixed in' n
convenient place fore and aft of the ship.
On the screw M are two nuts for the purpose of setting the apparatus and firml
securing it when its most advantageous position has been ascertained.

page_text: 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. The arrangement of a moving ball.
2. Cylinder, piston piston-rod two valve chambers and valves, pipes leading from
valve chambers to each end of cylinder.
3. Pipe connecting both valve chambers with condenser of main engines.
4. Levers for working valves.
5. A metal frame within which a ball of iron or other metal is allowed to roll in
a direction fore and aft of the ship, all working and constructed substantially as
shewn in this Specification and the accompanying drawings and for the purpose of
preventing or controlling the racing of marine engines when the propeller is
partially or wholly out of the water.
