Improved Oil or Gas Engine.
We, FREDERICK WILLIAM EAMES, 91, Tredegar Road, Bow, E., Confectioner,
and WILLIAM THOMAS SPEAIGHT, 54, Pitchford Street, Stratford, E., in the
County of Essex, Builder, do hereby declare the nature of this invention to be
as follows:
The princible of this oil or gas engine is, that the explosion takes place in
the center of two or three or four or more pistons, driveing them in opposite
directions, each piston is connected by a connecting rod to a crank, each crank
turning a pionion, each pionion turning one spur wheel aranged in the center
of two three four or more said pionions, the said engine is sutible for the
motor cars.

We, FREDERICK WILLIAM EAMES, of 91, Tredegar Road, Bow, E., Confectioner,
and WILLIAM THOMAS SPEAIGHT, 54, Pitchford Street, Stratford, E., in the
County of Essex, Builder, 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 an improved oil or gas engine the principle involved
in its construction and combination being that the explosion takes place in an
explosion chamber common to and between two, three, four or more pistons to
effect their propulsion in opposite directions. The piston cylinders are arranged
around the explosion chamber and the piston rods are linked or connected each
to a crank or eccentric-crank-pin upon a pinion wheel each pinion being
mounted in and upon a common bearing and gearing with a spur wheel arranged
and working together with the said pinions and common to the same, so as to
suppress vibration and to distribute evenly the effect of the combustion upon
each ignition taking place in the combustion chamber.
In order that the said invention may be well understood there is annexed
hereto drawings which will be referred to in the following more particular

page_text: description, by figures and letters of reference, like letters referring to similar
parts throughout the drawings.
Fig. 1, is a side elevational view with part of the cover plate broken away
to show details of the fitting of an engine made with four cylinders.
Fig. 2, is a central vertical transverse section of Fig. 1.
Fig. 3, shows in side elevational view an engine of similar construction but,
without water jacket and adapted for use as a light motor device.
Fig. 4, is a partial central transverse section through cylinders of Fig. 3, but
with the pistons and details not shown.
Referring now more particularly to Figs. 1, and 2, the engine is contained
in a casing consisting of back plate G, through a centre boss whereof passes and
is carried the main transmission shaft J, said shaft J, having keyed thereon the
spur wheel F, gearing with and driven from the pinions A. Upon the other
side of said spur wheel F, and constituting a portion of the casing is the plate G¹,
which is extended to carry the bodies of the cylinders wherein are located and
work the pistons B, the rods whereof are jointed at their outer ends to the
cranks C, of the pistons A.
The plate G, of the casing is extended to correspond with the extensions of
the plate G, to serve as bearings for the cross shafts A', carrying the pinions A;
G³, is a cover plate bolted on at G³, to the engine casing.
This cover plate is made with water spaces g, to correspond with water space g,
of the plate G¹, (see Fig. 2), and communicating through the spaces g, (see Fig. 1)
between the walls of the cylinders, so providing a water jacket. Extending
from the casing plate G³, is the inlet pipe D, for the explosive mixture, fitted
with valve D, of ordinary kind required therefor, such as is indicated and
leading to the combustion chamber H, common to the whole of the cylinders.
E, represents the exhaust pipe controlled by valve E', in like manner for that
purpose. d, indicates an electrical ignition means for the explosive mixture
received into the combustion chamber H.
The operating of the inlet and exhaust valves may be made in substantially
known manner, but there is indicated on the inner periphery or it may be on
the side face of the spur wheel F, as at M, cams to act on rollers, such as m,
(Fig. 3,) carried upon an arm centred at m¹³, and carrying a tappet n, to operate
the opening of the valves as the cycle of operation proceeds.
In Fig. 3, this is shown as applied to the inlet valve, and in Fig. 1, the tappet
is indicated as in connection with the exhaust.
In Figs. 1 and 2, there is shown at N, a balance or fly wheel carried on an
extension of one of the cross shafts A¹ of one of the driving pinions.
This engine may be arranged to work in a horizontal position if required
instead of vertically as shown.
In Figs. 3 and 4, the cylinders are shown with radiating ribs thereon instead
of being fitted with the water jacket provision.
The combustion chamber is shown with a tubular isolation centre way or
sleeve P, around the shaft J.
For the small motor engines as shown in Figs. 3 and 4, a fly wheel will not
necessarily be required, as the spur wheel F, may be sufficient to balance the
working.
The framing or foundations in or upon which the engine is mounted are not
shown, as the same will vary in many instances.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
-
First. The improved oil or gas engine, as herein specified, constructed, com-
bined and operating as and for the purpose herein described in reference to and
shown by the respective figures of the drawings.
Secondly. In motive power engines, as herein specified, the combination of

page_text: two or more cylinders and pistons having a common combustion chamber, said
pistons being connected with the cranks C, pinions A, spur wheel F, on the
main motion shaft J, and having the inlet and exhaust valves operated and con-
trolled by cams of the spur wheel F, as and for the purpose set forth.
