Improvements in or relating to the Arrangement of the Air and
Exhaust Valves of Internal Combustion Engines.
I, JAMES BAZELEY PETTER of The Nautilus Works, Yeovil, in the County of
Somerset, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the arrangement of the air and exhaust valves of gas
or petroleum or other internal combustion motors and is as follows:-
The air valve (which may be of any suitable construction and operated in any
suitable manner) is arranged and mounted diametrically or immediately opposite
the exhaust valve (which latter may also be of any suitable construction and
operated in any suitable manner) advantageously the air valve arranged vertically
over the exhaust valve or vice versa in such manner that after removal of one of
the said valves (for the purpose of cleaning etc.) the other valve can also be-
removed (for cleaning etc.) through the opening occupied by the former for instance
the exhaust valve can be removed through the space occupied by the air valve
after the latter has been removed thus facilitating the cleaning of the valves etc.

Improvements in or relating to the Arrangement of the Air and
Exhaust Valves of Internal Combustion Engines.
I, JAMES BAZELEY PETTER, of The Nautilus Works, Yeovil, in the County
of Somerset, 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 :-
This invention relates to the air or feed and exhaust valves of gas or petroleum
or other internal combustion motors and is as follows:-
The air valve-which may be of any suitable construction or type (in the case
of an oil motor advantageously a combined air and oil feed valve of any suitable
type) operated and operating in any suitable manner-is arranged and mounted.
diametrically or immediately opposite the exhaust valve (which latter may also be
of any suitable construction and operated and operating in any suitable manner)
advantageously this feed valve arranged vertically over the exhaust valve (or vice
tersa) in such manner that after removal of one of the said valves (for the purpose
of cleaning etc.) the other valve can also be removed (for cleaning etc.) through
the opening occupied by the former for instance the exhaust valve can be removed.

page_text: through the space occupied by the air valve after the latter with its casting or
casing has been removed the port or opening through the wall or side of the
vapourising chamber or compression space or back end of the cylinder or leading
from the valve into said cylinder or compression space being of a size sufficiently
large to permit the withdrawal of the said exhaust valve therethrough thus
facilitating the cleaning of the valves, etc..
In the accompanying drawings-
Fig. 1 illustrates an oil motor having my present improvements applied
thereto, and
Fig. 2 is a vertical longitudinal sectional view-on a greatly enlarged scale-of
the back portion thereof showing the arrangement of the valves etc.
A is the vapourising chamber or compression space.
F is the air inlet and D the oil inlet; air and oil being admitted through the
inverted mushroom valve E.
P is the exhaust valve.
The casting R containing the inlet valve is bolted (or otherwise suitably removably
secured) to the vapouriser or body of the engine and when this casting is removed
not only can the valve E be readily withdrawn from said casting but the exhaust
valve P can be withdrawn through the opening A* for cleaning etc.
I is igniting device.
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 :-
1. In internal combustion engines-the arrangement of the inlet valve in a
casting or casing mounted immediately over or opposite to the exhaust valve in
suchwise that the latter can be withdrawn through the aperture left when the
said inlet valve and its casting or casing are removed from the engine substantially
in the manner and for the purposes hereinbefore described.
2. The arrangement of the valves of internal combustion engines substantially
in the manner and for the purposes herein before described and illustrated in the
drawings hereunto annexed.
