WILLIAM MORGAN-BROWN, of the Firm of Brandon and Morgan-Brown, Engineers
and Patent Agents, of 38, Southampton Buildings, London, and 1, Rue Laffitte,
Paris. "IMPROVEMENTS IN THE MEANS OF EXERTING AND TRANSMITTING POWER
AND MOTION." [A communication from abroad by Robert Farley, junior, of New
York, United States of America, Gentleman.]
This Invention of improvements in the means of exerting and transmitting
power and motion relates to a means of exerting and transmitting power and
motion by the expenditure of a small amount of force; and the Invention consists
in the employment of four conical or funnel-shaped chambers containing liquid, such
as oil, water, or glycerine, and connected at their larger ends with a casing or
cylinder containing a sliding block fitted with double eccentrics upon a shaft, to
which motion is imparted by any suitable power.
The smaller ends of the funnel-shaped chambers are extended and form cylinders,
in which are arranged pistons, to the outer ends of the rods of which are attached
cross heads, connected to each other by rods or bais, so as to impart a mutually
reciprocating motion to the pistons.
The eccentrics on the central shaft actuate plungers or pistons arranged within
the larger ends of the liquid chambers which are cylindrical.
The Invention is designed to be applied to any machine or apparatus which
requires motive power, such as presses, and also to the propulsion of cars, vessels,
and other things requiring to be worked by power.

shaft is formed with double cranks set at right angles to each other, so as to avoid
centres, and so as to actuate alternately the two sets of pistons and plungers.
Upon the upper portion of each cylinder is a feed inlet provided with a slide
valve. The slide valves of each connecting cylinder are connected to a rod, and are
so arranged that as one inlet is open the other will be closed.
On the rod are projections, and on the upper rods are adjustable blocks or dogs,
which, as the rods move backward and forward with the pistons, strike against the
projections and move the slide valves, so as to alternately open and close the inlet
passages.
The slide valves are provided with chests, and are connected by pipes with a
reservoir of oil or other liquid, conveniently located and at a proper height to give
the requisite pressure for the feed.
The valve of each cylinder is designed to be opened at the limit of the outward
throw of the pistons, so as to supply any deficiency of oil. The valves serve also to
relieve the cylinders of any surplus oil, and act both as a feed and relief to the
cylinders, which is essential to ensure uniform motion.
For the purpose of aiding the plungers in passing centres a recess is made in the
head of the plunger, in which is fitted a stout spiral spring which bears against the
interior piston, to which is bolted a cup provided with suitable leather packing.
The main cup or head of the plunger is provided with leather packing. The
main cup is secured to the body of the plunger by means of screw bolts.
Holes through the main cup admit of the passage of the oil from the cylinder to
the interior piston. Power is to be applied to the shaft to move the pistons by
steara or other suitable means.
In operation, the shaft and eccentrics being put in motion, the plungers are
reciprocated. The amount of liquid displaced by the plungers moving through a
small space in the larger portion of the cylinders is sufficient to fill the sinaller
portions to the extent of forcing out the pistons to give them the requisite length
of stroke.
In some cases one cylinder alone may be used, as in an application to a jack. In
other cases two cylinders may be required.
In applying the machine to moving cars four cylinders may be used.

WILLIAM MORGAN-BROWN, of the Firm of Brandon and Morgan-Brown, Engineers
and Patent Agents, of 38, Southampton Buildings, London, and 1 Rue Laffitte,
Paris. IMPROVEMENTS IN THE MEANS OF EXERTING AND TRANSMITTING POWER
AND MOTION." A communication from abroad by Robert Farley, junior, of New
York, United States of America, Gentleman.
This Invention of improvements in the means of exerting and transmitting
power and motion relates to a new means of exerting and transmitting power and
motion by the expenditure of a small amount of force; and the Invention consists
in the employment of four conical or funnel-shaped chambers containing liquid,
such as oil, water, or glycerine, and connected at their larger ends with a casing or
cylinder containing a sliding block fitted with double eccentrics upon a shaft, to
which motion is imparted by any suitable power.
The smaller ends of the funnel-shaped chambers are extended and form cylinders,
in which are arranged pistons, to the outer ends of the rods of which are attached
cross heads, connected to each other by rods or bars, so as to impart a mutually
reciprocating motion to the pistons.
The eccentrics on the central shaft actuate plungers or pistons arranged within
the larger ends of the liquid chambers, which are cylindrical.
The Invention is designed to be applied to any machine or apparatus which
requires motive power, such as presses, and also to the propulsion of cars,
vessels, &c.
Referring to the Drawings,-
Figure 1 represents a sectional side view of a machine embodying my Invention;
Figure 2 is a sectional plan view of the same.
And Figure 3 is an enlarged view in section of the elastic piston.
A, A, A, A, represent the cylinders which contain the fluid, and in which the
pistons play.
The cylinders consist each of an enlarged cylindrical portion a, a tapering por-
tion b, and a smaller cylindrical portion c. In the enlarged portion a are fitted
the pistons or plungers B, B; and in the smaller portions c, c, are fitted the pistons
F, F. The liquid used is contained between the two pistons in each cylinder.
Supported centrally between the double cylinders A, A, is a shaft S, upon
which, and forming a part of the same, are two eccentrics C, C, arranged on opposite
sides of the shaft, as shewn in Figure 2. These eccentrics bear against sliding
blocks, which move the large pistons or plungers B, B, each one alternately in
opposite directions.
To the outer ends of each piston rod F are attached the cross heads I, I, which
are connected by the rods K, K. The cross heads are connected to the crank
shaft by the arms H. The shaft G is formed with double cranks set at right
angles to each other, so as to avoid centres, and so as to actuate alternately the two
set of pistons and plungers.
Upon the upper portion of each cylinder A is a feed inlet O provided with a
slide valve M. The slide valves of each connecting cylinder are connected to a
rod N, and are so arranged, that as one inlet is open the other will be closed.
On the rod N are projections 1, 7; and on the upper rods K are adjustable blocks
or dogs L, which, as the rods K move backward and forward with the pistons,
strike against the projections 1, 1, and move the slide valves, so as to alternately
open and close the inlet passages 0, 0.
The slide valves are provided with chests and are connected by pipes, with a
reservoir of oil or other liquid conveniently located, and at a proper height to give
the requisite pressure for the feed.

page_text: The valve of each cylinder is designed to be opened at the limit of the outward
throw of the pistons, so as to supply any deficiancy of oil. The valves serve also
to relieve the cylinders of any surplus oil, and act both as a feed and relief to the
cylinder, which is essential to ensure uniform motion.
For the purpose of aiding the plungers in passing centres I construct them as
shewn in Figure 3. A recess is made in the head of the plunger B, in which is
fitted a stout spiral spring V, which bears against the interior piston O, to which
is bolted the cup Y provided with suitable leather packing. P is the main cup
or head of the plunger, and is provided with the leather packing R. The main
cup is secured to the body of the plunger B by means of screw bolts p, p.
T, T, represent holes through the main cup P to admit of the passage of the oil
from the cylinder to the interior piston. Power is applied to the shaft S to move
the pistons by steam or other suitable means.
In operation, the shaft and eccentrics being put in motion, the plungers B, B, are
reciprocated. The amount of liquid displaced by the plunger B moving through
a small space in the larger portion a of the cylinders is sufficient to fill the smaller
portion c to the extent of forcing out the pistons to give them the requisite length
of stroke.
In some cases one cylinder alone may be used, as in an application to a jack. In
other cases two cylinders may be required.
In applying the machine to moving cars I design to use four cylinders, as shown
in the Drawings.
Having now described and particularly set forth the nature of the said Invention,
and the manner of carrying the same into effect, I would have it understood that
what I claim is,―
First. The combination of the conical end chambers, their cylindrical extensions,
the small pistons, the intermediate piston cylinder, and its large reciprocating
plunger, all arranged so that motion imparted to the plunger will be communicated
to the pistons by intermediate bodies of liquid, substantially as set forth.
Second. The combination of the cylindrical chamber, the plunger, the operating
block (or its equivalent), and the eccentric, as described.
Third. The combination of the end liquid chambers, the cross heads, and the
connecting rods, as specified.
Fourth. The combination of the liquid chambers and of the central plunger with
the eccentric and the driving shaft, substantially as and for the purpose set forth.
Fifth. The combination with cylinders A of the inlet passages O and the slide
valves M, connected together and operated by the dogs L on the rod K, as and for
the purpose specified.
Sixth. The combination with a cylinder A of a piston having an elastic centre,
constructed and operating substantially as and for the purpose set forth.
In witness whereof, I, the said William Morgan-Brown, have hereunto set my
hand and seal, this Fifteenth day of June, in the year of our Lord One
thousand eight hundred and seventy-eight.
