Office of the Commissioners of Patents, with his Petition, on the
.
8th December 1874.-A communication from abroad by Aaron R.
Klein, of New Jersey, in the United States of America.
I, ISAAC COWLES COLTON, of Queen Victoria Street, in the City of
London, do hereby declare the nature of the said Invention for “Iì-
PROVEMENTS IN THE CONSTRUCTION OF GOVERNORS OR REGULATORS FOR STEAM AND
OTHER MOTIVE-POWER ENGINES,” a communication from abroad by Aaron
R. Klein, of New Jersey, in the United States of America, to be as
follows: :—
"
This Invention consists in constructing governors or regulators for
steam and other motive-power engines in such a way that the speed of
the said engines may be regulated more accurately than heretofore.
The Sheet of Drawing accompanying this Specification shows two
views of a governor constructed according to this Invention.
DESCRIPTION OF THE DRAWING.

Figure 1 is a voutioal soation from front to rear, and Figure 2 is a

page_text: ';
On the said Drawings, a represents a spindle having near its upper
end the arms b, b', branching outwards and upwards at an angle of
about 45 degrees, and at the uppermost end of the said spindle a is a
thread upon which is screwed a cap c of peculiar shape, it having an
indentation or groove c' completely encircling its lower part. At the
outer ends of the arms b, b¹, are pivoted the ball rods d, d³, the said ball
rods having at their lower ends the centrifugal balls e, e', and at their
upper ends rounded or cylindrical shaped slides f,f, which fit into the
grooves c¹ formed around and into the cap c, the said groove c¹ being
deep enough to allow the slides f,f¹, to enter to a greater or less distance
as the cap c is turned further downwards or upwards upon the threaded
end of the spindle a.
The spindle a passes through a plate g and rests
in a socket a' on the base plate h of the governor, shown in this instance
as fastened immediately upon the top of the throttle valve. The plate g
is supported at its proper heighth by two columns i, i¹; the said columns
are connected to the plate h, resting thereon. The columns i, ', are
grooved lengthwise on their inside surface, into which works the slide j
of a sleeve, the side edges of the slide j fitting into the grooves of the
columns so that the said slide may be moved up or down as desired.
At the top edge of the said slide j is attached a rod k extending upwards
therefrom and through the plate g before mentioned, threaded at its upper
end with a nut, thumb screw, or lever cap k¹, so that by turning the
said cap k¹ the sleeve j¹ may be raised or lowered as desired. Inside the
sleeve ¹ is a spindle or shaft lying horizontally, and having at its
interior end a disc l, and at the back of the disc a cog wheel m; the face
of the disc opposite to the shaft is dished, with rim bevelled inwards,
and corresponding thereto is a sleeve o upon the spindle a fastened
thereto permanently, and so arranged that when the spindle a is raised
an upper bevel o¹ is brought in contact with the bevel of the disc Pat
that point, and when the spindle a is dropped downwards a lower bevel o'
of the sleeve o comes in contact with the lower edge of the disc / fitting
to its bevel so that the said disc may be revolved cither by motion
applied to its top edge or below, as may be desired. At n is shown a
yoke (one side n¹ being toothless) which gears with the cog wheel m, so
that according to the direction in which the said cog wheel is turning
the yoke n will be raised or lowered. The yoke n is astride the cog
wheel m, but only in contact when in gear. Below the yoke n arms p
are brought together connecting it with the valve rod q, which rod runs
downwards through the plate h into the valve chamber connecting

page_text: the cap c at the top of the spindle a when the engine is at rest, or by
means of the lever cap k¹ when the engine is in motion.
In order to adapt the governor to engines moving in opposite
directions the rack n¹ need only be reversed on the pinion, causing the
cogs to gear on the opposite side.
