PROVISIONAL SPECIFICATION.
Improvements in Steam, Compressed Air, or other Fluid Engines for
Torpedoes or other Centrifugal or Rotary Purposes.
WILLIAM TURNER LORD Architect &c. Stamford Brook Villa Hammersmith
London, do hereby declare the nature of this invention to be as follows :—
The formation of single or multiple cylindered engines for use in torpedoes &c.
with the axes of the cylinders parallel to the line of centre of revolving shaft.
One arrangement for effecting this purpose is as follows. I form an engine with
three cylinders the plan of which would form a trefoil, in these cylinders are trunk
pistons having tubular extensions thereon (either one or more) and either with a
single passage or divided into passages for steam or other fluid (or else a form of
spindle valve) these passing through steam tight ways in cylinder covers, into one
or more chambers; for the conveyance of steam. In the trunk pistons I place
oscillating or other valves connected with the piston rods, and at other ends, to
crank pins on side of bevel wheels which work on a bevel wheel centred to main
shaft of machine or I use any other method of toothing or friction gear &c. to
change the reciprocating motion into rotary, at right angles, and 1 also arrange to
compound my engines.

COMPLETE SPECIFICATION.
Improvements in Steam, Compressed Air, or other Fluid Engines for
Torpedoes or other Centrifugal or Rotary Purposes.
WILLIAM TURNER LORD Architect &c. Stamford Brook Villa, Hammersmith
London do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
I will first describe a three cylindered engine specially arranged for propelling a
torpedo.
Fig. 1. is a vertical section, and Fig. 6 is a plan of the cylinders, valve boxes &c.,
and Fig. 7, a plan of the bevel geared wheels, with crank pins attached by which
it will be seen that the axes of cylinders are parallel with propeller shafts F & G,
the inner one in this case being used as an exhaust passage, is hollow: but in somo
cases may be solid.
The action of the engine is as follows, the pressure fluid which I will term steam,
enters at M and through the valve H and passage I belonging to its respective
cylinder A, and acting upon the piston P with its connecting rod N, gives motion
to the geared bevel wheel C which has the crank pin B upon its back.
The wheels CCC rotate in opposite directions the wheels D D, which are
connected to the shafts F & G, and in this case are arranged to contra drive two
propellers which can be fixed upon the shafts F & G.
The pressure of steam on top of piston valve H keeps it in contact with the
shaped ridge on top of D, marked E the varying height of which moves the valve
Successively into positions for steam supply & exhaust, the latter taking place when
shoulder of H is raised above passage I, through K or other convenient outlet, but
if desirable eccentric or other valve gearing may be substituted for E in which
case the position of the valve chamber, in relation to cylinder; may be changed to
suit, and reversing gear may be adopted in the case of a capstan or steering
engine &c. O is a convenient form of framework into which are fixed the centres
upon which CCC revolve.

page_text: In Fig. 2, instead of the piston valves, a rotary valve L, is shewn, placed on top
or cover of cylinders, having a steam inlet M and an exhaust passage K; this
valve may be balanced or otherwise and also combined with a reversing valve, one
form of which is indicated by R. which can be actuated by means of the rod which
passes through the gland. These rotary valves can be moved by the rod S being
connected to the wheel D. N.B. similar parts are marked with the same letters in
all the figures. Where contra driven shafts are not required, one of the wheels D
may be omitted.
I provide for the use of the trefoil or triangular plan of cylinders in combination
with engines for which Patents Nos. 6044, 7105, 10488 all 1890, have been granted
me, also for a modified form shewn in Fig. 3 by which the oscillating valve T,
actuated by the rod N, alternately opens and closes supply and exhaust to cylinder,
and the elongated trunk piston cuts off supply and exhaust, for expansion and
compression; the cover of cylinder is shaped to upper side of piston.
The use of two or more of any of these cylinders &c. successively increasing in
size, can be used for compounding.
Other methods of compounding are shown in Figs. 4 & 5 in each of which,
A represents the high pressure cylinder U the intermediate receiver and V the low
pressure cylinder.
In Fig. 4 the high press piston P is carried by the tubular extension of piston Q,
and is used, partly as the intermediate receiver, and to convey steam from U to V
through the ports in the oscillating valve T. which is connected to the rod N, and
which, on the up stroke, through the rod N being moved to the opposite angle by
the throw of the crank thereby closes these ports. The piston valve H admits
steam from M by ports X & passage Y to A. when down, as shewn in Fig. 4; and
when up, steam passes from A to U through passage Y, space in valve Y and
passage Y, the exhaust from V is through passage W to K when valve is raised :
but it may also be arranged to exhaust by means of the oscillating valve T, as in
Patent 6044-90 granted to me.
In Fig. 5, the valve H is arranged, so that when down, steam passes from the
supply M through ports X and passage Y to A, and at the same time steam passes
from U to V through Z. Z and W. When the valve is up, as in drawing; steam
passes from A to U by Y. Y² & Y₁; and exhausts from V to K by passage W.
The valves H H may have balance cylinders &c. at top if desired. The rods
connecting the two pistons move in any convenient steam tight ways or packing and
when suitable, ordinary cranks may be used.
In some cases, when the pressure fluid contains heat, as in the case of high
pressure steam, or any system of exploded, or chemically generated gases (as for
example one proposed by M. Nobel) and it is desirable to expand more than twice,
a further cylinder and valve may be added: Also in the event of condensation
being required, this can be done by means of an equilibrium valve allowing steam
to pass to underside of low pressure piston on the return stroke, and then opening
to condenser on next down stroke, in which case the rod of low press piston must
work in a steam tight way: or the exhaust of any of the forms of engine described
may if required be connected to condenser apparatus.
In some cases it may be found convenient to invert the arrangement of cylinders
in these single acting engines.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1. The combinations herein described for single or multiple cylindered engines.
2 The arrangement of cylinders as herein described.
