PROVISIONAL SPECIFICATION.
Improvements in Gas Motor Engines.
1, HUGH CAMPBELL, of Well Lane Halifax, in the County of York, Gas
Engine Manufacturer do hereby declare the nature of this invention to be as
follows:-
According to the present construction of gas engines, the explosive mixturo passes
in a stream direct from the ignition chamber to the compression chamber, and inter-
mingles with the spent gases therein, whereby the unspent gases are weakened and
the power obtained therefrom is lessened. The object of my invention is to obtain
the greatest possible force of the gases, and this "I accomplish by a more equal
distribution of the said gases.
In carrying out my invention I employ a distributing disc or plate occupying a
position between the ignition chamber and the compression chamber, so that as the
gases enter they impinge against the said disc whereby the said gases are distributed
and enter the compression chamber in a more diffused state, by which means their
strength is better maintained. The distributing disc may be perforated, or it may
be made from fine wire gauze, so as to permit the gases to pass through in a diffused
stream.

COMPLETE SPECIFICATION.
Improvements in Gas Motor Engines.
I, HUGH CAMPBELL of Well Lane, Halifax, in the County of York, Gas
Engine Manufacturer, 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 :-
-
According to the present construction of gas engines, the explosive mixture
passes in a stream direct from the ignition chamber to the compression chamber
and intermingles with the spent gases therein, whereby the unspent gases are
weakened, and the power obtained therefrom is lessened. The object of my inven-
tion is to obtain the greatest possible force of the gases, and this I accomplish by a
more equal distribution of the said gases.
In carrying out my invention I employ a distributing disc or plate, occupying a
position between the ignition chamber and the compression chamber so that as the
gases enter they impinge against the said disc, whereby the said gases are distributed
and enter the ignition chamber in a more diffused state by which means their
strength is better maintained.
In order that my invention may be more fully understood, I will now describe
the same with reference to the annexed sheet of drawings illustrative thereof,
wherein
Fig. 1 is end elevation of the ignition chamber of a gas motor engine, and
Fig. 2 is sectional plan of same, the compression chamber, which is adjoining up to
it, being removed or not shewn, as not being necessary to assist in explaining the
nature of my invention, which is shewn at A, and comprises a disc or plate of
suitable shape and material. The disc is kept in position by screws and nuts B,
made to enter into the metal part of the ignition chamber, as the drawing
indicates.

page_text: It will be observed that the disc is fixed so that the underside of it, is some
distance away or clear of the mouth or orifice C, of the ignition chamber, so that
as the stream of combustible mixture is let in and passes along the ignition
chamber, they impinge against the disc where they become diffused and spread out
on every side of the disc, and as the piston within the compression chamber
approaches the disc, for compressing the gases, they are sent back into the ignition
chamber, the disc again distributing the gases whereby they are far more diffused
than would be the case if they were not intercepted by the disc, consequently their
strength is better maintained."
The distributing disc may be perforated, or it may be made from fine wire gauze
so as to permit gases to pass therethrough in a diffused stream.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what 1
claim is :-
Firstly. In a gas motor engine, the use of a solid disc or plate for dis-
tributing the combustible mixture in manner substantially as herein shewn and
described.
Secondly. In a gas motor engine, the use of a perforated disc or plate, or wire
gauze, for distributing the combustible mixture in manner substantially as herein
shewn and described.
