Improvements in Gas and Explosive Vapour Motors.
I, ALFRED ROWE BELLAMY, of Algoa Lodge, Adswood Lane, Stockport, in the
County of Chester, Engineer, do hereby declare the nature of this invention to
be as follows:-
My said invention relates to improvements in gas and similar motor engines
and has for its object, to arrange for, a more convenient and efficient disposal
of the various valves which regulate the passage of the vapour to and from the
cylinder. According to my invention the valves are so disposed as to dispense
with the usual ports leading from such valves to the cylinder.
In carrying my invention into effect the cylinder end casting is arranged to
carry the air valve, exhaust valve, and gas valve, the air valve and exhaust valve
Leing vertically disposed one opposite the other. The said air valve spindle is
carried in a plug secured to the cylinder end casting the valve itself finding its
seat against the interior of the combustion chamber of the cylinder, being held
thereto by means of a spring as is usual. The pendent exhaust valve which is
of the usual or suitable description is inserted in the cylinder end casting and
lies opposite to the air valve the outer wall of such exhaust valve being kept
cool by passing through the water jacket to the interior of the combustion
chamber. The gas inlet valve which is preferably self-contained is arranged
horizontally in the cylinder end and leads into the air valve chamber at right
angles to a line drawn down the centre of the air valve spindle.
In order to give greater water space the interior face of the cylinder end, which
constitutes one wall of the combustion chamber, may be of a curved or concave
form.
It will be understood that the various levers and parts which actuate the
various valves are so arranged as to suit the improved disposal of the said valves.
With the horizontal arrangement of gas valve, I employ a sliding wedge to act
on such gas valve spindle, the wedge being operated by the usual hit-and-miss
tappet.

I, ALFRED ROWE BELLAMY, of Fordsburg, Edgeley, Stockport, in the County
of Chester, late of Algoa, Lodge Adswood Lane Stockport, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement and accompanying drawings:-
My said invention relates to improvements in gas and similar motor engines
and has for its object to arrange for a more convenient and efficient disposal
of the various valves which regulate the passage of the vapour to and from the
cylinder. According to my invention the valves are so disposed as to dispense
with the usual ports leading from such valves to the cylinder.
To render my invention clear, I have attached hereto an illustrative sheet of
drawings, to which I will, throughout the following description, refer.
In the said drawings:-
-
Fig. 1 is a vertical section of the cylinder end casting with the valves arranged
in accordance with my invention.
Fig. 2 is a side elevation of Fig. 1 looking in the direction of arrow.
Fig. 3 represents a vertical cross section of the cylinder end taken at right
angles to Fig. 1.
Fig. 4 shows a modification of my invention the position of the valves being
inverted.
In carrying my invention into effect, the cylinder end casting A, is arranged to
carry the air valve a, exhaust valve b, and gas valve c, the air valve and exhaust
valve being vertically disposed, one opposite the other, as clearly shown in Fig. 1.
The spindle a¹ of the air valve a is carried in a plug a² secured to the cylinder
end casting A, the valve itself finding its seat against the interior of the com-
bustion chamber d of the cylinder, and being held thereto by means of a
spring, as is usual.
The pendent exhaust valve which is of the usual, or suitable description, is
inserted in the cylinder end casting and lies opposite to the air valve a, the outer
wall of such exhaust valve being kept cool by passing through the water jacket c
to the interior of the combustion chamber. The gas inlet valve c, which is pre-
ferably self contained, as shown in the drawings, is arranged horizontally in the
cylinder end, and leads into the air valve chamber at right angles to a line drawn
through the centre of the air valve spindle.
Instead of having the air and gas valves, at the top of the cylinder, these
valves may be arranged below, in the position occupied by the exhaust valve in
the arrangement indicated in Fig. 1, the exhaust valve 6 in such case being dis-
posed at the top of the cylinder.
This modification of my invention is illustrated in Fig. 4 of the drawings.
It will be understood that the various levers and parts, which actuate the
various valves, are so arranged as to suit the improved and particular disposal
of the said valves.
With the horizontal arrangement of gas valve, I may use the hit and miss
tappet or I may employ a sliding wedge to act on such gas valve spindle, the
wedge being operated by the usual hit and miss tappet.
In order to obtain greater water space on the outside of the combustion chamber,
and at the same time to reduce the surface of the combustion chamber which is
in contact with the water, the interior face f of the cylinder end A, which con-
stitutes one wall of the combustion chamber, may be of a curved or concave form,
as shown in Fig. 3.

page_text: Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare, that what
I claim is:-
In gas and explosive vapour motors, disposing the air and exhaust valves
vertically, one opposite the other, in the cylinder end casting, such air and exhaust
valves passing through the water jacket space, so as to dispense with ports, the
gas valve leading into the air valve, in the manner, and substantially as herein
described.
