I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, 118, New Street, Birmingham, in the County of
Warwick, & 322, High Holborn, in the County of Middlesex, Civil Engineer, lo
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 improvement in multi-cylinder power engines, such
as gas, petroleum, benzine and the like engines, which is intended to render the
same more particularly suitable for driving vehicles. In order to correspond as
fully as possible to this object, the machines must not only be of a compact formi
of construction, but they must be closed to the outside in their moving parts so
as to completely exclude the dust.
These requirements are endeavoured to be fulfilled in the present invention by
the following arrangements, which are shown in the accompanying drawings in
Figures 14, the same carrying out the object to a greater extent than any
other forms of construction hitherto known.
The multi-cylinder power machine or engine is enclosed in a casing G which is
dust-tightly closed on all sides. Each two adjacent cylinders work on a common
crank shaft a which at both sides is provided with cranks or crank discs b.
In order that the crank shaft may be carried to the outside through the casing
not as is the case with the older forms of construction by means of stuffing boxes,
the power is taken not from the crank shaft but from a subsidiary shaft located
between the cylinders which is operated or driven from the crank shaft by means
of a pair of bevel wheels gg. The subsidiary shaft is carried to the outside
through a stuffing box h and is provided with a disc i common to all the cylinders,
which disc by means of suitable levers koperates the inlet and outlet valves in the
ordinary manner so that said shaft acts both as driving shaft and valve operating
shaft. At the other end the said subsidiary or valve operating shaft carries a cog-
wheel, belt pulley or the like from which the power is taken. The arrangement
herein before described necessitates accordingly one valve operating shaft only
which simultaneously serves for delivering the power and which also allows of the
casing being only perforated at one place, and therefore it affords the various/
advantages mentioned at the commencement of this specification, namely that the
machine is of an uncommonly simple form of construction and all the movable parts
are entirely protected from the outside against the action of dust.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is:
A multi-cylinder power engine, characterised by a valve operating shaft (f)

which shaft is operated from a crank shaft receiving the power from all the
cylinders and carries outside the casing in addition to the valve operating disc,
the driving wheel from which the power is delivered, substantially as hereinbefore
described.
