PROVISIONAL SPECIFICATION.
Improved Arrangement of Appliances connected with Internal
Combustion Engines.
We, JOSEPH WANE, of 2 Trigon Grove, Kennington, London, and JOHN
GEORGE HORSEY, of Corcelles, Bromley Grove, Shortlands, Kent, Engineers,.
do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved arrangement of appliances connected with
internal combustion engines.
To effect this we close the front end of the cylinder by a cover gland stuffing
box or other means, and make the piston hollow. Ports and valves are arranged
in the piston block and cylinder. The back stroke of the piston draws in a charge
of gas and air or vapour and air into the front end of the cylinder where it is
retained by a valve. The forward stroke compresses this mixture into the hollow
piston where it is retained by a valve until about one fourth of the return stroke
is completed when the charge is admitted into the back end of the cylinder by
suitable ports and valves.
The further motion of the piston compresses the charge which is suitably
exploded for forcing the piston forward in the usual manner.
Our invention is applicable to engines having either fixed or oscillating
cylinders.

We, JOSEPH WANE, of 2 Trigon Grove, Kennington, London, and JOHN
GEORGE HORSEY, of Corcelles, St. John's Road, Sidcup, Kent, Engineers, do
hereby declare the nature of this invention aud 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 arrangement of appliances connected with
internal combustion engines.
To effect this, we close the front end of the cylinder by a cover gland stuffing
box or other means, and make the piston hollow. Ports and valves are arranged
in the piston block and cylinder.

page_text: In operation the back stroke of the piston D draws in a charge of gas and air
or vapour and air into the front end of the cylinder A where it is retained by a
cock or valve L. The forward stroke compresses this mixture into the hollow
piston D where it is retained by a valve P until the forward stroke is completed or
later if desirable when the charge passes the valve Q into the back end of the
cylinder and drives the products through the exhaust valve R now open by action
of cam T and lever S.
The back motion of the piston D compresses the charge which is suitably
exploded by the igniter H for forcing the piston forward in the usual manner.
The hollow piston D has an inclined back face which the internal pressure tends
to keep the piston in contact with the cylinder on the ported side in opposition to
the pressure within the piston to prevent leakage.
Our invention is applicable to engines having either fixed or oscillating
cylinders.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The improved internal combustion engines whether of the oscillatory or of the
fixed cylinder type, as represented in the annexed drawings, the working parts being
arranged as and for the purposes described.
