Improvements in Oil and other like Motors.
I, THOMAS WARSOP, of Coniston, in the County of Lancashire, Engineer, do
hereby declare the nature of this invention to be as follows:-
The object of my invention is to form a simple combination of two single-acting
oil or other like motor engines; each fitted with an improved piston, so constructed
as to obviate or minimise the shocks due to the explosion of the gaseous mixture
in the cylinders from being imparted to the other parts of the motor.
For this purpose I fix the two motor cylinders in one water cooling jacket
common to both; which jacket is firmly attached to a framing provided with two
or more bearings for carrying the crank shaft of the motor.
This crank shaft may have its cranks at opposite, quarter, or any other desirable
centres one with another. This latter framing I cover with a suitable cover, so
as to enclose all the moving parts contained therein.. The exhaust, or consumed
products of combustion pass at the required times from the two cylinders, into
the outer chamber of a circular casing attached to the ends of the motor cylinders
furthest away from the crank shaft; and from thence to the atmosphere. The
action of this exhaust is controlled by an exhaust valve in each cylinder, actuated
by a suitable lever or levers and gearing from the crank shaft of the motor.
Into the inner or vaporizing chamber of this circular casing, I admit a suitable
quantity of petroleum, or other oil, or the like; which is vaporized by the heat
from the exhaust gases in the outer chamber, and also by the heat from a lamp
placed in the centre of the circular casing. This lamp is also used to heat the
ignition tubes attached to the motor cylinders for igniting the explosive charge
therein. The vaporized oil is drawn from the vaporizing chamber, and mixed
with a suitable quantity of air in passing past a self-acting valve placed in the
exploding end of each motor cylinder; this mixture being drawn into the cylinders
by the outward stroke of each piston, which compresses the mixture on its return
stroke ready for ignition on its next outward stroke.
I construct the piston of each cylinder of two or more single ended cylinders
or, trunks, one within the other; the inner one to which the connecting rod is
attached sliding freely inside the outer one, which fits the motor cylinder and is
fitted with the usual piston rings. In a space between the outer end of the trunk
and the inner end of the outer trunk-and attached to both-I have a spiral or
other spring or springs, or other suitable elastic buffer, so arranged that any
explosive force applied to the end of the trunk compresses the spring-or-springs
between the ends of the trunks, and so minimises the shock of such explosion from
being imparted to the other parts of the motor.

page_text: I may also fit the motor with the usual fly wheel, governors, driving wheels,
and other parts as is usual and necessary for employing the motor for any purpose.

I, THOMAS WARSOP, of Coniston, in the County of Lancashire, 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:
The object of my invention is to form a simple combination of two single-acting
oil or other like motor engines; each fitted with an improved piston, so constructed
as to obviate or minimise the shocks due to the explosion of the gaseous mixture
in the cylinders from being imparted to the other parts of the motor.
For this purpose I fix the two motor cylinders in one water cooling jacket
common to both; which jacket is firmly attached to a framing provided with two
or more bearings for carrying the crank shaft of the motor.
This crank shaft may have its cranks at opposite, quarter, or other desirable
centres one with another. This latter framing I cover with a suitable cover, so
as to enclose all the moving parts contained therein. The exhaust or consumed
products of combustion pass at the required times from the two cylinders, into
the outer chamber of a circular casing attached to the ends of the motor cylinders
furthest away from the crank shaft; and from thence to the atmosphere. The
action of this exhaust is controlled by an exhaust valve in each cylinder, actuated
by a suitable lever or levers and gearing from the crank shaft of the motor.
Into the inner or vaporizing chamber of this circular casing, I admit a suitable
quantity of petroleum, or other oil, or the like; which is vaporized by the heat
from the exhaust gases in the outer chamber; and also by the heat from a lamp
placed in the centre of the circular casing. This lamp is also used to heat the
ignition tubes attached to the motor cylinders for igniting the explosive charge
therein. The vaporized oil is drawn from the vaporizing chamber, and mixed
with a suitable quantity of air in passing past a self-acting valve placed in the
exploding end of each motor cylinder; this mixture being drawn into the cylinders
by the outward stroke of each piston, which compresses tlie mixture on its return
stroke ready for ignition on its next outward stroke.
I construct the piston of each cylinder of two or more single ended cylinders
-or trunks, one within the other; the inner one to which the connecting rod is
attached sliding freely inside the outer one, which fits the motor cylinder and is
fitted with the usual piston rings. In a space between the outer end of the trunk
and the inner end of the outer trunk-and attached to both-I have a spiral or
other spring or springs, or other suitable elastic buffer; so arranged that any
explosive force applied to the end of the trunk compresses the spring or springs
between the ends of the trunks, and so minimises the shock of such explosion from
being imparted to the other parts of the motor.
"
I may also fit the motor with the usual fly wheel, governors, driving wheels,
and other parts as is usual and necessary for employing the motor for any purpose.
In order that my invention may be fully understood, and more readily carried
out and into effect, I have appended hereunto two sheets of drawings whereon:--

page_text: Figure 1 represents a plan of my improved motor, with the cover. removed from
the crank shaft end.
Figure 2 represents an elevation of the same improved motor nearly all in
section.
Figure 3 represents an end view or elevation of the cylinder end of my motor,
partly in section.
Similar letters of reference indicate similar parts throughout the various figures.
In these figures C, C are the two motor cylinders fixed in the water cooling
jacket A common to both; this jacket A is secured to the framing B, which is
provided with two or more bearings D, D for carrying the crank shaft E of the
motor. This shaft has its cranks E¹ E', at opposite, or other desirable centres one
with the other. I prefer to cover the framing B with a suitable cover F, so as to
enclose the moving parts therein.
The exhaust or consumed products of combustion pass away from the cylinders,
at the required times, into the outer chamber G of the circular casing V attached to
the ends of the motor cylinders C, C; and from thence into the atmosphere. The
action of this exhaust is controlled by the exhaust valves H, H, which are actuated
by the lever I worked by gearing from the crank shaft E, or by other suitable
means.
Into the vaporizing chamber K of the circular casing V, I admit a suitable
quantity of petroleum, or other oil from a pump or tank; this oil is vaporized
by the heat from the exhaust gases passing out along the chamber G, and also
by the heat from a lamp placed in the centre L of the circular casing V. This
lamp is also used to heat the ignition tubes J, J attached to the cylinders C, C for
igniting the explosive charge therein. The vaporized oil is drawn from the
vaporizing chamber K along the pipe K¹, past the self-acting valves M, M placed
in the exploding chamber of cach cylinder C, C; this mixture is drawn into the
cylinders by the outward stroke of each piston P, which compresses the mixture
on its return stroke ready for ignition on the next outward stroke.
I construct the piston P of each cylinder of two or more trunks N and P one
within the other; the inner one N to which the connecting rods R, R are attached,
slides freely inside the outer one P which fits the cylinder, and is fitted with the
usual piston rings. In the space between the outer end of the trunk N and the
inner end of the trunk P, and attached to both, I have a spiral or other suitable
elastic buffer S; so arranged that the force of the explosion in the cylinder against
the end of the trunk P compresses the spring or springs S, and so reduces the
shock of such explosion to any parts of the motor.
In some cases I may fit to the explosion chamber of the motor cylinder, one or
more small. pressure chambers; each fitted with a piston sliding freely therein,
and having one or more springs placed between this piston and cover bolted to
the outer end of such chamber, which is in communication with the motor
cylinders. The object of this chamber or chambers being to act as a reservoir to
take part of the force of explosions in the motor cylinders, and to give off again
such force as is imparted to the pistons of this pressure chamber, to the pistons of
the motor cylinders C, C.
I fit the motor with the usual fly wheel, governors, driving pulley, and the like.
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 :-
1st. In oil and other motors the combination of one or more elastic or spring
cushioned pistons P, P and the cylinders C, C, for the purposes mentioned, and
substantially as set forth herein and shown on the drawings herewith.
2nd. In motor engines the combination of one or more pressure chambers fitted
with a spring weighted piston as described, and one or more motor cylinders for
the purposes specified and substantially as hereinbefore described and set forth
herein.

page_text: 3rd. In motor engines the arrangement and combination of parts as shown in
Figures 1 to 3 inclusive for the purposes mentioned and substantially as herein-
before described and shown on the drawings herewith.
