Year: 1896

Complete Specification Left, 25th Aug., 1897-Accepted, 2nd Oct., 1897
I, JOHN POWER, of Saltram Cottages, Zion Street, Plymouth in the County of
Devon, do hereby declare the nature of this invention to be as follows:-
My invention relates to the governing of oil, gas or vapour engines especially the
class of engine in which the crank works in a closed chamber and in which an
impulse is obtained at each revolution, such engines are described in Patent
Specifications 64101, 92479, and 1551495. In these engines air is compressed in
the chamber by the piston and is then passed into the cylinder to form a portion
of the charge.
To govern such engines I apply a valve controlling an aperture or opening in the
air chamber or an air pipe connected therewith. The valve is actuated by a ball or
other governor.
This arrangement when the valve is lifted from its seat by the governor attachment
allows some of the air compressed in the air chamber and also any oil that may have
found its way into the air chamber, to escape to a suitable chamber or reservoir.
Another means for governing such oil gas and vapour engines consists in applying a
valve controlled by a governor to the passage by which the air enters the engine.
This governing is thus effected by regulating the air supply only.
Improvements in Governing Oil, Gas and Vapour Engines.
I, JOHN POWER, of Saltram Cottages, Zion Street, Plymouth, in the County of
Devon, 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 :-
My invention relates to the governing of oil, gas or vapour engines especially the
class of engine in which the crank works in a closed chamber and in which an
impulse is obtained at each revolution, such engines are described in Patent
Specifications 641091, 924791 and 15514. In these engines air is compressed in
the chamber by the piston and is then passed into the cylinder to form a portion of
the charge.
To govern such engines I apply a valve controlling an aperture or opening in the
air chamber or an air pipe connected therewith. The valve is actuated by a ball or
other governor

The drawings show the arrangement fitted to the pipe leading from air reservoir to
the cylinder.
Figure 1 is a vertical section on the line 1-1 Figure 2 and Figure 2 is a
horizontal section on the line 2-2 Figure 1.
A is a casting bolted onto the side of the engine and A' is the air pipe formed in
it having openings A' A' and A' respectively into the cylinder, the air reservoir and
the valve chest B.
V is the valve.
O the outlet to the waste reservoir (not shown).
N are regulating nuts.
L the governor lever.
S attachments from the lever to the valve.
Pa spring, and -
D the centre line of the lever when the valve is open.
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. Governing engines of the class referred to by regulating the air supply
substantially as described.
2. Mechanism for governing engines substantially as described and shown in the
drawings.
