COMPLETE SPECIFICATION,
Improvements in Gas and Oil Engines and the like.
We, JAMES FREDERICK BENNETI, of 18, Violet Bank Road, Nothe Edge,
Sheffield, Engineer, HEDLEY STANLEY MOORWOOD, and THOMAS PARKIN MOORWOOD,
both of the Harleston Works, Sheffield, Engineers and Ironfounders, all of the
County of York, do hereby declare the nature of our said invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement
1
The objects of our invention are two-fold, IZ
1 To improve the construction of the cylinder and water jacket so that there
may be no water joints between the jacket, the combustion chamber or the work-
ing barrel of the cylinder
2. An improved arrangement of valve box on the said cylinder, by means of
which the valve box or cover with the valves and the valve arms or levers which
actuate the same, may be taken off the cylinder for examination or repairs with-
out interfering with the gas and exhaust pipes or their connections With the
exception of these improvements we construct our engine in a manner smilar to
that employed in other types of gas or oil engines.
Our invention will be better understood on 1eference to the accompanying
sheet of drawings, in which,
Fig. 1 represents a side elevation of the cylinder and valve box of one of our
improved gas engines.
Fig 2 is an end elevation of the same
Fig 3 18 a plan
Fig 4 18 a side elevation of the cylinder, the valve box being removed.
Fig. 5 is a longitudinal section taken through the centre of the cylinder jacket
and piston
Fig. 6 is a transverse section of the same taken on the line A B.
The same letters refer to similar parts throughout the several views
We carry out our invention in the following mannei
Firstly, we construct our improved cylinder and water jacket in two parts, the
working barrel, F, of the cylinder we form so as to carry the back portion of the
water jacket, G¹, and likewise the gas inlet, H, and exhaust outlet, H, in one
casting, the forward or main portion of the water jacket, G, is formed as part of
the body casting of the engine, concentrically with the forward portion of this
water jacket we bore a hole for the reception of the forward end of the working
barrel, F, of the cylinder and on the rear end of the forward portion of the water
Jacket, G, which is attached to the body of the engine, we form a flange, I, and
we likewise form a corresponding flange, J, on the rear portion of the water
Jacket, G¹, which 18 connected to the working barrel F, of the cylinder, and by
means of which the two parts are bolted together The forward end of the work-
ng barrel of the cylinder and the hole for its reception are accurately tuined and
bored so as to allow of a water tight joint being made by forcing the same into
position by hydraulic power or otherwise It will be seen that by this mode of

jacket and working barrel or combustion chainber of the evlinder
Secondly, by our improved arrangement of valve box, the valve box, K, which
canes the gas and exhaust valves, L, M, and likewise the brachet, N, which
canes the actuating aim 01 levels with then appui tenant fittings, is secured
u the after portion of the cylinder by bolts or studs P, Q, R, S, so that by remov-
ing the nuts the several parts just enumerated may be litted off and removed for
examination, adjustment, cleaning, or repans, as the case may be, when s0
removed, a port T, is uncovered so that access may be had to the working banel
and combustion chamber of the cylinder for examination or cleaning, and in like
manner the gas and exhaust ports, H, H', are likewise exposed by the removal of
the said valve box so that they can likewise be examined and cleaned and all this
can be effected without disturbing any of the pipe connections or motive parts of
the engine
Having now particularly described and ascertained the nature of our said inven-
tion, we declare that what we claim is
-
1 In a gas or oil or the like engine, the improved construction of the cylinder
and water jacket so that there may be no water joints between the jacket, the
combustion chamber, or the working barrel of the cylinder, substantially as
herein described and illustrated in the several figuies on the accompanying sheet
of drawings.
2 In a gas or oil on the like engine, an improved arrangement of valve box
by means of which the valve box or cover with the valves, the valve aims or lever
which actuate them, and then appui tenant fittings may be taken off the cylindeı
for examination or repairs without interfering with the gas and exhaust pipes or
their connections or any other motive parts of the engine, substantially as herein
described and illustrated
3 In a gas or oil or the like engine, the arrangement and combination of parts
and appliances embodied in the improvements set forth in the respective Claims 1
and 2, in the manner and for the purposes substantially as herein described and
illustrated.
