PROVISIONAL SPECIFICATION left by the said Richard Waygood at
the Office of the Commissioners of Patents, with his Petition, on
the 4th May 1872.
I, RICHARD WAYGOOD, of the Newington Iron Works, Falmouth
Road, in the County of Surrey, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE CONSTRUCTION AND ARRANGEMENT
OF STEAM AND OTHER ENGINE GOVERNORS, AND IN VALVES TO BE USED IN CONNECTION
THEREWITH," to be as follows:—
This Invention relates to the construction and arrangement of steam
and other engine govenors, and consists mainly in fitting one or two

page_text: flat plate springs (singly or built up of several plates) to clips, lugs,
or joints at both ends to give freedom of action. The springs have
semi-spherical or other shaped balls or weights attached rigidly at or
near the centres of the plates, which the speed forces outwards to draw.
one of the clips, lugs, or joints attached to the valve spindle closer to. 5
the other clip, lug, or joint, and thus to shut off the steam or other
fluid to the required degree.
The valves I propose to uso in connection with the govenors before
mentioned are of cylindrical form and work in a chamber open at each
.end, so that the steam or other fluid acts upon both ends of it. The 10
chamber has a port on one side or on opposite sides, through which the
steam is free to pass to the engine, the ports being opened and closed
more or less under the action of the governor.
The chamber is formed in a casting of cylindrical or spherical shape,
and the passages are so shaped in the casing that the steam gets divided 1
in its transit through the casing and then unites to enter the steam
tube or the engine as the case may be.
It is not essential in.all cases to divide the steam, as one passage only
· SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said Richard Waygood in the Great Seal Patent Office
on the 4th November 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
WAYGOOD, of the Newington Iron Works, Falmouth, Road, in the
-County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of May, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Richard Waygood, Her special licence;
that I, the said Richard Waygood, my executors, administrators, and
assigns, or such others as I, the said Richard Waygood, my executors,
administrators, and assigns, should at any time agree with, and no

page_text: others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN THE CONSTRUCTION AND ARRANGEĶENT OF STEAM AND OTHER ENGINE GOVERNORS,
AND IN VALVES TO BE USED IN CONNECTION THEREWITH," upon the condition'
(amongst others) that I, the said Richard Waygood, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to
bo performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Richard Waygood, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof, reference being had to the Drawings here-
unto annexed, that is to say:-
This Invention relates to the construction and arrangement of steam
and other engine governors, and consists mainly in fitting one or two
flat plate springs (singly or built up of several plates), to clips, lugs, or
joints at both ends to give freedom of action. The springs have semi-
spherical or other shaped balls or weights attached rigidly at or near
the centres of the plates, which the speed forces outwards to draw one of
the clips, lugs, or joints attached to the valve spindle closer to the other
clip, lug, or joint, and thus to shut off the steam or other fluid to the
required degree.
The valves I propose to use in connection with the governors before
mentioned are of cylindrical form and work in a chamber open at each
end, so that the steam or other fluid acts upon both ends of it. The
chamber has a port on one side or on opposite sides, through which
the steam is free to pass to the engine, the ports being opened and
closed more or less under the action of the governor.
The chamber is formed in a casting of cylindrical or spherical shape,
and the passages are so shaped in the casing that the steam gets divided
in its transit through the casing and then unites to enter the steam
tube or the engine as the case may be.

page_text: It is not essential in all cases to divide the steam, as one passage only
need be formed if desired.
The Invention will be well understood by the accompanying, Sheet
of Drawings, in which Figure 1 is a sectional elevation of the governor
and the parts connected therewith..
a, a, are two springs of flat steel with a spherical weight at or
about the centre; the upper ends of the springs are attached by joints
to lugs c, c, on the top of the valve rod d, their lower, ends being
similarly jointed to lugs e, e, which move round only upon the cap f.
The lower end of the rod d passes through the cap and the top flange ]
or gland g of the valve chamber; where it has a valve 6 attached for
determining the extent of opening through which the steam shall pass
to the engine. The portion of the chamber in which the valve moves
is formed with openings i, i, opposite each other to divide the steam
and produce an uniformity of action upon the valve. The steam 1
passes down the openings, or passages j, j, and reunites at % on its
way to the cylinder or cylinders. The steam entry is furnished with
a stop-cock 2, shown clearly in the transverse section Figure 2, it being
moved to and fro by a hand wheel or a lever in the usual manner.
The flat steel springs a, a, shown in Figures 1 and 3 are composed 2
each of two plates, one being shorter than the other; this is for the
purpose of obtaining greater rigidity at the centre; any number of..
these plates can be added or one plate only may be used. The valve b.
is perforated so that a portion of steam can pass through and act abové
and thereby equilibrate it and make it more sensitive than if left plain 2
for the steam to act upon its lower side only. I prefer to perforate it.
with five holes, as shown in Figure 4, but the holes may be lesser or
greater in number.
It will be seen that the valve rod d passes up through the socket
or bridle m and is connected to the top lug c by a nut n, so that on an 3
excess of speed being obtained by the engine the whorl p is caused to
run the faster and communicate its motion through the bevil wheels q, q,
´to the tuber to which the bottom lug is secured. Thus the weights
are driven outwards by centrifugal action, and the top lug c brought
down and also the rod d with the valve 6 which closes the openings i, i, 3
to the required degree and shuts off the supply of steam in proportion.

page_text: The employment of cylindrical valves as governor valves and against
which the steam can act upon both sides is an important feature in my
Invention, and I claim them in combination with a governor composed
of flat spring plates upon which weights are arranged in the manner.
and for the purposes set forth.
In witness whereof; I, the said Richard Waygood, have hereunto set
my hand and seal, this Fourth day of November One thousand
eight hundred and seventy-two.
