IMPROVEMENTS IN ENGINES FOR DRIVING, WINDING, AND PUMPING PURPOSES
Year: 1874

page_text: LETTERS PATENT to John Richardson, Engineer to the Firm of Robey
and Company, Limited, Perseverance Iron Works, Lincoln, for the
Invention of "IMPROVEMENTS IN ENGINES FOR DRIVING, WINDING, AND
PUMPING PURPOSES."
PROVISIONAL SPECIFICATION left by the said John Richardson at the
Office of the Commissioners of Patents, with his Petition, on the
12th October 1874.
•
I, JOHN RICHARDSON, Engineer to the Firm of Robey and Company,
Limited, Perseverance Iron Works, Lincoln, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN ENGINES FOR DRIVING,
WINDING, AND PUMPING PURPOSES," to be as follows:-.
This Invention relates mainly to an improved combination of parts,
whereby greater strength and solidity than is usual are obtained with
less vibration, more convenience for oiling and cleaning, the parts in
detail being fewer in number and easier got at.

page_text: The Invention is applicable to " portable," "semi-portable," and
"fixed," and is especially intended for those having the engine proper
upon the boiler and running at high speeds under a great pressure.
In carrying my Invention into effect I form the bearings, cylinder
cover, piston rod guide, exhaust pipe, and oil receiver in one casting.
The bearings partly embrace and partly rest upon the barrel of the
boiler at one end, and partly rest upon the boiler and partly against the
end of the cylinder by stepping it into the cylinder itself, where a flange
forms the attachment by bolts to the cylinder flange, the face of the
frame acting as the cover to the cylinder through which the piston rod
moves to and fro. The piston head or block moves in a guide, which is
also part of the frame of semicircular og segmental shape, the lower part
of the slide being solid to serve as an oil receiver.
The governor support projects from the side of the frame, as also that
for the pump barrel. The governor for this arrangement and others
form the second part of my Invention, and consists in mounting upon
the vertical spindle a loose fitting weight, preferably of spherical shape,
with slots in two sides for rods to be pinned in the rods projecting above
the sphere, where they are attached to the governor balls, so that as they
open out under centrifugal action they lift the weight, and thereby
control the passage of the steam to the cylinder or cylinders, the weight
having the slide or the throttle valve in connection in the usual
manner.
I purpose crossing the ball levers from opposite sides of the spindle
head, but the balls can hang from the same sides if necessary.
The exhaust pipe is formed in the frame of the engine, and terminates
in à bend leading to the chimney or uptake, a dip in the bend serving to
draw off the water from the condensed steam.
Among the advantages to be gained by my Invention is high measure
of expansion while running under great pressure, the cut-off or regu-
lation being effected by the governor, which in the form above described
is very sensitive and positive in its action.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Richardson in the Great Seal Patent Office
on the 10th April 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
RICHARDSON, Engineer to the Firm of Robey and Company, Perseverance
Iron Works, Limited, Lincoln, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of October, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Richardson, Her special licence
that I, the said John Richardson, my executors, administrators, and
assigns, or such others as I, the said John Richardson, my executors,
administrators, and assigns, should at any time agree with, and no
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
ENGINES FOR DRIVING, WINDING, AND PUMPING PURPOSES," upon the condition
(amongst others) that I, the said John Richardson, 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 be
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 John Richardson, 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, that is to say :-
This Invention relates,-

page_text: convenience for oiling and cleaning the parts in detail, being fewer in
number and easier got at.
Thirdly. To an improved form or arrangement of governor for
engines.
The Invention, as hereafter described, is applicable to "portable,"
semi-portable," and "fixed" engines, and is especially intended for
those having the engine proper upon the boiler and running at high
speeds under great pressure.
The manner of carrying my Invention into effect is as follows, and as
shown in the accompanying Drawings:-I form the bearings A, A,
cylinder cover B, piston rod guide C, exhaust pipe D, and oil receiver E
in one casting as a frame X, as in Figures 1, 2, 3, and 4, which are
respectively a side elevation and sections through the lines x, x, y, y.
The bearings A, A, partly embrace and partly rest upon the barrel F of
the boiler at one end and partly rest upon the boiler and partly against 1
the end of the cylinder G by stepping it into the cylinder itself, where a
flange H forms the attachment by bolts to the cylinder flange I. The.
face of the frame X acts as the cover to the cylinder, through which the
piston rod travels to and fro. The piston head or block J moves in the
guide C, which is also part of the frame of semicircular or segmental :
shape, the lower part of the slide being solid, as at K, to serve as an oil
receiver.
The governor support L projects from the side of the casting or frame
✗, as also that for the pump barrel N. The governor for this arrangement
and others.forms the third part of my said Invention, as before referred
to, and consists in mounting upon the vertical spindle P a loose fitting
weight Q, preferably of spherical shape, with slots a, a, in two sides for
rods b, b, to be pinned in. The rods project above the sphere Q, where
they are attached to the governor balls R, R, so that as they open out
under centrifugal action they lift the weight Q, and thereby control the a
passage of the steam to the cylinder or cylinders G, the weight having
the slide on the throttle valve in connection in the usual manner or as
shown by the lines c, c, c.
I purpose crossing the ball levers S, S, from opposite sides of the
spindle head T, but the balls can hang from the same sides if necessary.
The exhaust pipe D, which is formed in the frame of the engine,
terminates in a bend U leading to the chimney or uptake Y, a dip W in

page_text: the bend serving to draw off the water from the condensed steam by a
pipe fitted thereto.
Among the advantages to be gained by my Invention is high measure
of expansion while running under great pressure, the cut-off or regu-
lation being effected by the governor, which in the form above described
and as shown is very sensitive and positive in its action.
And having now described the nature of my said Invention and in
what manner the same is to be performed, I declare that I claim,—
Firstly. The formation of the main frames of engines used for winding,
driving, and pumping purposes in one casting of metal, as and for the
purposes set forth and substantially as shown in the accompanying Sheet
of Drawings, such main frames in all cases being upon the boilers
(portable and semi-portable) as described.
Secondly. I claim the combination of parts forming the engine proper
as described with reference to the accompanying Sheet of Drawings.
Thirdly. I claim the improved arrangement of parts forming a
governor for engines, as described.
In witness whereof, I, the said John Richardson, have hereunto set
my hand and seal, this Ninth day of April, One thousand eight
hundred and seventy-five.
