IMPROVEMENTS CONNECTED WITH PROAL
Year: 1881

page_text: LETTERS PATENT to Joseph Edlyn Outridge, of Egham, in the County of
Surrey, Engineer, for an Invention of "IMPROVEMENTS CONNECTED WITH
PROVISIONAL SPECIFICATION left by the said Joseph Edlyn Outridge at
the Office of the Commissioners of Patents on the 7th July 1881.
JOSEPH EDLYN OUTRIDGE, of Egham, in the County of Surrey, Engineer.
"IMPROVEMENTS CONNECTED WITH STEAM AND OTHER MOTIVE POWER ENGINES."
My Invention relates to an arrangement of mechanism whereby I obtain rotatory
motion from a reciprocating motion having neither connecting rod or crank as iu
ordinary engines.
The Invention consists in attaching to the piston rod of an ordinary steam or
other power cylinder a pump plunger working within another cylinder or barrel
so that a liquid or a fluid can be drawn in and ejected therefrom.
With the outflow or exit pipe of this pump I fit a casing, within which two
pistons are acted upon by the passing liquid or fluid as to cause them to rotate or
revolve therein. Each of these pistons has a series of vanes and apertures in their
peripheries to coincide with each other in the order of their rotation. The pistons
have shafts attached whose outer ends carry toothed or other gearing (coupled),
and on a pinion being thrown to gear with either of these toothed or other gearing
so will the direction of rotation of the shaft of the pinion be governed.
To the pump barrel I arrange a condenser into which the exhaust steam from
the cylinder is allowed to pass and be condensed to produce a vacuum in the
opposite portion of the double piston cylinder to that at which the liquid or fluid
enters to assist the rotation of the two rotatory pistons.
By my Invention, supposing it to be fitted in a steam yacht, the captain or
person in charge could have absolute control over the action of the screw, and be
wholly independent of the engine driver, stoker, or of any one on board, for the
propulsion, the dropping astern, or the backing of the vessel.

My Invention relates to an arrangement of mechanism whereby I obtain rotatory
motion from a reciprocating motion having neither connecting rod or crank as in
ordinary engines.
The Invention consists in attaching to the piston rod of an ordinary steam or
other power cylinder a pump plunger working within another cylinder or barrel
so that a liquid or a fluid can be drawn in and ejected therefrom. With the outflow
or exit pipe of this pump I fit a casing within which two pistons are acted upon
by the passing liquid or fluid as to cause them to rotate or revolve therein. Each
of these pistons has a series of vanes and apertures in their peripheries to coincide
with each other in the order of their rotation. The pistons have shafts attached
whose outer ends carry toothed or other gearing (coupled), and on a pinion being
thrown to gear with either of these toothed or other gearing, so will the direction
of rotation of the shaft of the pinion be governed.
To the pump barrel I arrange a condenser into which the exhaust steam from
the cylinder is allowed to pass and be condensed to produce a vacuum in the
opposite portion of the double piston cylinder to that at which the liquid or fluid
enters to assist the rotation of the two rotatory pistons.
By my Invention, supposing it to be fitted in a steam yacht, the captain or
person in charge could have absolute control over the action of the screw, and be
wholly independent of the engine driver, stoker, or of any one on board, for the
propulsion, the dropping astern, or the backing of the vessel.
My Invention will be clearly understood by the annexed Sheet of Drawings, in
which Figure 1 shows an elevation of a combined steam engine A, a pump B, and
a rotary engine C, by which the screw propeller D can be rotated to the right or
to the left under the action of the gearing E, F, and pinion G (see Figure 2) the
pinion being controlled by the hand lever H to throw it into the teeth of E or of F
when desired.
The steam engine A is of the ordinary construction, and its piston rod I has
connected to it the plunger of the pump B, so that water can be drawn into the
barrel B by the reciprocating action from a tank J, such as is shown at Figures 3
and 4, by the pipe or pipes K, K, and be forced through the pipe or pipes L, L, to
the barrel C to act upon or against the surface M of the drums N, N, and the
blades P, P, thereon (see Figure 5) to force the drums round the blades P, P, inter-
locking into the spaces Q, Q, alternately as they turn. The water follows the
motion of the drums N, N, and leaves the barrel C by the outlet R and the
exhaust pipe S to the tank J to be re-used in a similar manner. The drums N, N,
are supported in the casing C by axles T, T', as seen more particularly in Figure 3,
one of which rotates in a long sleeve U to steady it, and the other T in a stuffing
box V. This axle may be the screw-shaft, as in Figure 3, or a shaft may be
coupled or keyed to it for communicating motion therefrom. Nozzles may be
fitted in the rotator to divide and direct the entry of water.
Any other method of effecting a reversing rotative action of the screw or other
shaft T may be employed, and in some cases three-way taps may be employed for
directing the rotation of the drums N, N.
In every case I gear the two axles T, T¹, T, T¹, of each casing C to ensure the
blades P, P, engaging into the spaces Q, Q, and of the drums working together.

page_text: Figure 5 shows a modified placement or position of the barrel C to those shown
at Figures 1 and 3, but any other position to suit circumstances may be adopted.
The water may enter the barrel C at the upper part, as shown in Figure 4, or at
the side, as at Figure 3, or at the lower, as in Figure 6, in which Figure the
blades P, P, are coupled so as to move transversely in the drum N, which in this
case is single, while in Figure 5 I show two single or uncoupled drums, being acted
upon by a single column of water which becomes divided and passes off by the
pipes S, S. The spent steam from the engine A may advantageously be sent into
a condenser in connection with the pump barrel to produce a temporary vacuum on
the back of the plunger after the delivery of the water. In Figure 1 the combination
would suit a fair sized propeller vessel; Figure 5, a launch or a yacht; Figure 4
being more particularly adapted as a land engine.
Having now described the nature of my said Invention, and in what manner the
same is to be performed, I declare that I claim,-
The combination of the three engines A, B, C, working in unison for producing
or obtaining rotatory motion from a reciprocating motion without the use of con-
necting rods or cranks, and the utilization of such rotatory motion, as set forth, for
driving screw propellers or for general purposes.
In witness whereof, I, the said Joseph Edlyn Outridge, have hereunto set
my hand and seal, this Ninth day of September, in the year of our Lord
One thousand eight hundred and eighty one.
