Improvements in and relating to Oil, Gas, and Vapour Engines.
We, HERBERT TUBB, of 40 Cranbury Avenue, Cabinet Maker, and ALBERT
EDGAR MONDEY, of 106 High Street, Cabinet Maker, both of Southampton, in
the County of Hants, 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:-
Our invention relates to engines, more especially to the fly wheel and cranks of
oil, gas, and vapour engines, used for marine work, that is for the propulsion of
vessels, but it is obvious our improvements may be applied to engines used for
other purposes.
For a marine engine it has been generally found necessary hitherto-for various
reasons to fit a vertical fly wheel on the horizontal shaft of considerable diameter,
which has proved objectional by reason of the consequent raising of the shaft to
allow of the free revolutions of the fly wheel clear of the bottom of the vessel.
Our invention has for its main object the doing away with the necessity for
fitting a vertical fly wheel by substituting for same a horizontal fly wheel on the
top of the engine, thus enabling the propeller shafting to be fitted low down in the
vessel.
In the accompanying drawings we have shewn what we consider to be the best
way of carrying out our invention, illustrating for the purpose part of a horizontal'
single cylinder oil, gas, or vapour engine, in which :-
Fig. 1. is a horizontal elevation of a part of an engine constructed according to
our invention.
Fig. 2. a plan on top of Fig. 1.
Fig. 3. an enlarged sectional elevation of details hereinafter described.
A, is the cylinder, B, the connecting rod, C, the crank, D, part of the frame
work of the engine.
Like letters indicate corresponding parts throughout the drawings.
According to one form or modification of our invention we mount the fly wheel E,
at the top of the engine on the vertical shaft F, to which it is keyed, and provide
for the weight of the fly wheel E, to be taken by the balls G, G, which run in
grooves formed at the underside of the fly wheel, and in a moveable plate n, which
when in place bears fairly on the flange of the bush H. But we may, or may not,
as found convenient also fit balls J, J, in similar manner at the underside of the
crank C, or we may only fit balls J, J, under the crank as shewn instead of fitting
them under the fly wheel as shewn, and it is obvious that if the balls are fitted
under the crank the weight of the fly wheel and crank will be taken by them.
We have shewn bevel wheel gearing K, K, arranged for driving the propeller
shafting L, and clutch gear b, for putting same in and out of gear when stopping,
starting, and reversing the propeller; but we do not limit ourselves to the use of
such gear but may use worm wheel or any gear found suitable for the object
in view.
By arranging for the weight of the fly wheel to be taken by balls directly or
indirectly, as herein before described, a considerable advantage with reference to
the rotary movement of the fly wheel must necessarily follow and consequently in
the speed and general efficiency of the engine.
A possible further advantage in the same direction would be secured by also

page_text: fitting balls J, J, as shewn under the crank, as well as the balls G, G, directly
under the fly wheel.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1st. The improvements in engines consisting of the parts constructed and
arranged substantially as herein before described with reference to the accompanying
drawings, and operating as, and for the purpose specified.
2nd. An engine wherein the fly wheel is fitted and arranged so as to revolve
horizontally upon balls-directly or indirectly-the latter being carried by the
framework of the engine as, and for the purpose set forth.
3rd. An engine wherein the vertical weight of fly wheel, crank, and vertical
shaft is carried or taken by balls running in suitable bearings substantially as
described.
4th. The combination with an engine of the above mentioned type of a horizontal
fly wheel arranged to revolve on balls, in suitable bearings, supported on the frame-
work of the engine snbstantially as described with reference to the accompanying
drawings for the purpose specified.
Dated this 29th day of April 1806.
