Complete Specification Left, 19th July, 1895-Accepted, 24th Aug., 1895
PROVISIONAL SPECIFICATION.
An Improved Gas and Petroleum Motor.
I, THOMAS RICHARD SHILLITO of 89 Chancery Lane London, W.C., Engineer,
do hereby declare the nature of this invention, a communication to me from
abroad by The Leipziger Dampfmaschinen und Motoren Fabrik, of Leipzig-
Plagwitz in the German Empire, to be as follows:-
This invention relates to a gas or potroleum motor in which two pistons
reciprocate in a single cylinder with the combustion space between said pistous.
The movement of each piston is transmitted through a piston rod and oscillating
double lever to a crank shaft located below the cylinder, the two cranks being
connected together by a rod. The cylinder has an inlet and outlet for the gases.
The cylinder and the working parts are enclosed in a casing closeable at the two
ends by means of covers and when these are removed the cylinder and working
parts are accessible. The bottom part of the casing is supplied with a lubricant
which is so driven about by the working parts as to lubricate automatically these
parts and the cylinder whilst the escape of disagreeable smells into the surrounding
space or engine room is prevented.
Dated this 22nd day of October 1894.

COMPLETE SPECIFICATION.
An Improved Gas and Petroleum Motor.
1, THOMAS RICHARD SHILLITO of 89 Chancery Lane, London, W.C.,
Engineer, do hereby declare the nature of this invention, a communication to inǝ
from abroad by The Leipziger Dampfmaschinen und Motoren Fabrik, of Leipzig-
Plagwitz in the German Empire, 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 this invention is on the one hand to prevent the escape from gas
and petroleum motors of disagreeably smelling gases into the surrounding space or
engine room and on the other hand to enable all bearings and pistons to be
automatically lubricated by oil supplied to the bottom of the motor casing and
dashed about therein by the working parts so as to effect such lubrication.
The invention mainly consists in arranging a gas or petroleum motor, having two
pistons working in a single cylinder, in a closed casing. Such a motor is shewn
in Fig. 1 of the drawing in end elevation and in Fig. 2 in side elevation.
A is the motor casing so formed as to enclose the complete motor comprising two
pistons a working in a single cylinder B with the combustion space between said
pistons. The movement of each piston is transmitted through a piston rod d, an
oscillating double lever c and a connecting rod d to a crank shaft K located below
the cylinder and carried in bearings, one in each side of the motor casing A, which
latter is provided at both ends with openings for ready access to the working parts
of the motor, and readily closeable by covers f. i is the inlet and outlet for the
gases into and out of the cylinder. : is the cooling water space.

page_text: 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 :-
In a gas or petroleum motor in which two pistons a work in a single cylinder B
with a combustion space b between said pistons and transmission of the piston
movement through piston rods d, levers c and connecting rods d³ to a crank shaft
located below the cylinder, the motor casing A which completely encloses said
cylinder, ievers, rods and crank shaft and which is provided at both ends with
openings readily closeable by covers and allowing access to the working parts, for
the purpose. specified, substantially as described and shewn.
Dated this 19th day of July 1895.
