Improvements in Explosion Engines or Motors.
I, SAMUEL MILLER, of 6, Hilda Road, Brixton, S.W., Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in explosion engines or motors, the
object being to so construct a motor of this description as to combine a maximum
of efficiency with a minimum size of motor, further to allow of the parts being
readily separated or removed for repairs etc., and to secure perfect alignment
of the operating pistons, and in this way to obtain a compact and efficient motor
of comparatively great power, which is particularly suitable for use in connection
with motor vehicles and motor driven boats, although it may obviously be
employed for other purposes for which it is suitable.
In carrying this invention into practical effect, I employ one cylinder only
bored throughout its length, which is closed at each end, and divided approxi-
mately at the centre by a diaphragm or partition into two chambers. Within
each chamber I arrange a double piston consisting of a cylindrical block
sufficiently turned out or recessed at each end to form an explosion chamber,
while each double piston is furnished with a pin or part projecting through
slots formed in the side of the cylinder of a length in proportion to that of the
stroke, and these two pins at or near their outer extremities are united by a
connecting bar or rod so that both pistons partake of a common simultaneous
motion, which may be communicated to a crank disc, crank axle or the equiva-
lent by a single connecting rod, so that the connecting and operating gear being
preferably arranged at the side of the cylinder.
Valve gear of any suitable form may be employed to allow of the charge being.
taken in at either side of either of the double pistons as required, and they may
be so arranged as to have the whole of the pistons in active operation at one
time or one only of them may be employed, and where the whole of them are
in active operation, impulse is given at each half revolution.
The whole of the motor is preferably constructed without a base plate, but is
supported by legs or arms designed to be bolted or clamped, in the case of
motor vehicles, to tubular members of the frame.
Packing rings of the usual form may be employed, or to enable these to be
dispensed with, the ends of the pistons may be turned or bored out to such an
extent as to reduce the sides of the pistons at these points, which form the
explosion chambers, to such a thinness, that upon compression or explosion
they will expand sufficiently to form a gas-tight joint between them and the
sides of the cylinder.

page_text: 1, SAMUEL MILLER, of 6, Hilda Road, Brixton, London, S.W., Engineer, 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:-
This invention relates to explosion engines or motors, the object being to so
construct a motor of this description as to combine a maximum of efficiency
with a minimum size of motor, further to allow of the parts being readily

pistons, and to obtain a compact and efficient motor of comparatively great power,
which is particularly suitable for use in connection with motor vehicles and
motor driven boats, although it may be employed for other purposes for which
it is suitable.
This invention consists essentially in the employment of a single cylinder
bored throughout its length which is closed at each end and divided approxi-
Within
mately at the centre by a diaphragm or partition into two chambers.
cach chamber a double piston is arranged consisting of a cylindrical block
sufficiently turned out or recessed at each end to form an explosion chamber,
while each double piston is furnished with a pin or part projecting through
slots formed in the side of the cylinder of a length in proportion to that of
the stroke, and these two pins, at or near their outer extremities, are united by a
connecting bar or rod, so that both pistons partake of a common simultaneous
motion, which may be communicated by a single connecting rod to a crank dise,
crank axle, or its equivalent.
:-
In order that my invention may be more fully understood, I will now proceed
to describe same with reference to the accompanying drawings, in which:
Fig. 1 is a sectional plan of the essential parts of an explosion engine or
motor constructed according to this invention.
Fig. 2 is a cross section taken through a cylinder such as may be employed
for use in connection with this invention.
Fig. 3 is a detailed view shewing means whereby the main driving axle may
be mounted upon the tubular members or rods of the frame of a motor vehicle.
According to this invention, a single cylinder a is employed, furnished with a
suitable water jacket b. This cylinder is bored throughout its length while it
is closed at each end c and divided by a partition or diaphragm d, arranged
approximately at the centre, into two chambers gg. Within each chamber a
double piston is arranged consisting of a cylindrical block, sufficiently turned
out or recessed at each end to form an explosion chamber e.. Each of the double
pistons is furnished with a pin f projecting through slots h formed in the side
of the cylinder a and water jacket b, and these two pins are united at or near
their outer extremities by a connecting rod or bar j, so that both pistons p P
partake of a common simultaneous motion, which may be communicated by a
single connecting rod k to a crank disc such as m mounted upon the main
driving axle n.
Valve gear of any suitable and well known form and operated in the usual
manner may be employed to allow of the charge being taken in at either side
of either of the double pistons in a proper sequence as required, so that while
explosion is taking place at one end of one of the double pistons, at the other
extremities, compression, charge taking, and exhaust, are occuring in their
proper order.

page_text: As shewn in Fig. 2, the cylinder may be sufficiently cut away at one side
so as to form a flat surface q, against which slides, carried by the rod or bar 3,
bear and slide backwards and forwards during the operation of the motor or
engine, for covering the slots h, while upon the lower part of the outer jacket
of the cylinder, clamping pieces r may be cast, or formed in any other suitable
manner, so as to allow of the said cylinder being clamped to the tubular
members or rods of the frame of the vehicle, while as shewn at Fig. 3, the
main driving axle n may be supported in suitable bearings o cast or formed with
downwardly projecting extremities, terminating in clamping ends #designed
to grip the tubular members or rods of the frame, of the vehicle, or in the case
of a motor driven boat, these downwardly projecting extremities may be
furnished with suitably shaped parts designed to be clamped or bolted to the
floor, but where it is designed to be employed as a stationary engine, it can be
arranged or formed in connection with a suitable base plate in any convenient
manner.
In connection with the pistons packing rings of any suitable and well
known kind may be employed, while the cylinder may be formed in two or
more sections designed to be united to form a complete cylinder and divided
by a partition or diaphragm into two chambers as herein before described, more-
over, the operating parts consisting of the cylinder a, pistons pp, rod or bar j
connecting rod k and crank disc m, may be duplicated where additional power is
required, in which case the second set of operating parts are preferably arranged
upon the same tubular members or rods of the frame of the vehicle as the first.
and by the side thereof and parallel thereto.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is:
1. A new or improved explosion motor or engine consisting essentially of a
single jacketted cylinder a, closed at each ende, and divided approximately
at the centre by a partition or diaphragm such as d into two chambers g g
within each of which is arranged a double piston turned out or recessed at
each end to form an explosion chamber e, each piston being further provided
with a pin f passing through slots h in the side of the cylinder and united by
a connecting rod or bar so that both pistons partake of a common simul-
taneous motion, which is communicated to a crank dise such as m, a crank axle,
or the like, by a single connecting rod k, the whole arranged in combination with
suitable valves, and valve operating and ignition mechanism of any well known
kind, substantially as herein described and shewn with reference to the accom-
panying drawings, and for the purposes specified.
2. In an explosion engine or motor such as above claimed, the employment
of a single double chambered cylinder, substantially as set forth.
3. In an explosion motor or engine, the employment of a single cylinder
such as a, divided into two chambers such as g g, in combination with two
double pistons one arranged in each chamber g g which are. turned out
or recessed at each end to form explosion chambers such as e, and united by a
connecting bar or rod such as through parts or pins such as f projecting
through slots in the side of the cylinder, so as to partake of a common simul-
taneous motion, substantially as herein described and shewn with reference to
the accompanying drawing, and for the purposes specified.
