PROVISIONAL SPECIFICATION.
Improvements in or connected with Explosion Engines.
We, GEOFFREY HOWARD and EDWARD TENNEY BOUSFIELD, both of
Bedford, in the County of Bedford, Engineers, do hereby declare the nature of
this invention to be as follows:-
Our invention relates to explosion engines and has for its object to provide
improved means for rendering them portable.
In carrying out our invention we dispense with the usual heavy foundation or
base and we mount the cylinder and the working parts in connection upon a
channelled steel frame carried by road travelling wheels and fitted with the
ordinary shafts for moving the engine.
The channelled bars of the frame are suitably spaced to take the engine
working parts, and in the space between the channel bars two tanks are fixed
one of which for the oil is under the cylinder (an oil force pump if desired being
fixed upon the said tank) whilst the other, which is for water, is of special
construction, that part above the axle of the fore travelling wheels being made
deeper than the other portion. With this arrangement the travelling wheels when
being locked for turning will clear the deeper part of the tank and pass under the
shallow part, whereby we obtain large tank capacity and facility for moving the
engine about on its travelling wheels.
The apparatus for maintaining the working cylinder at the proper temperature
consists of a cooling vessel having an open bottom and supported over the water
tank, in which cooling vessel boards are arranged in tiers crossing each other.
A space is left between the top of the water tank and the cooler to allow the free
ingress of the air current. The heated water from the cylinder jacket is lifted to
the top of the cooler by a force pump or other suitable means and is sprinkled on
the top tier of boards whence it trickles down over the several tiers into the

understood that the water in its descent through the cooler meets the ascending
current of air which is preferably induced by the exhaust gases from the
cylinder being ejected from a nozzle into a chimney or funnel fixed on the top of
the cooler.

Improvements in or connected with Explosion Engines.
We, GEOFFREY HOWARD and EDWARD TENNEY BOUSFIELD, both of
Bedford, in the County of Bedford, Engineers, 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 explosion engines and has for its object to provide
improved means for rendering them portable.

In carrying out our invention we dispense with the usual heavy foundation or
base and we mount the cylinder and the working parts in connection upon a
channelled steel frame carried by road travelling wheels and fitted with the
ordinary shafts for moving the engine.
The channelled bars of the frame are suitably spaced to take the engine working
parts, and in the space between the channel bars two tanks are fixed one of which
for the oil is under the cylinder (an oil force pump if desired being fixed upon the
said tank) whilst the other, which is for water, is of special construction, that part
above the axle of the fore travelling wheels being made deeper than the other
portion.
The apparatus for maintaining the working cylinder at the proper temperature
consists of a cooling vessel having an open bottom and supported over the water
tank, in which cooling vessel boards are arranged in tiers crossing each other.
A space is left between the top of the water tank and the cooler to allow the free
ingress of the air current.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawings, in which :-
:-
Figure 1 is a side elevation shewing an engine mounted upon a transporting
carriage and provided with tanks and a water cooler in accordance with our
invention :
.
Figure 2 is a front elevation of the same:
Figure 3 is a sectional elevation drawn to an enlarged scale of the water cooler;
and,
Figure 4 is a longitudinal vertical section through the tanks.
a, a are the channelled bars of the frame, which bars have bolted or rivetted to
them brackets b, 6 the former of which has fixed to it the axle c carrying the
rear travelling wheels d, d whilst the latter rests upon the fifth wheel or turn-
table e of a fore-carriage having suitable fittings for the connection thereto of horse
shafts or other draught appliances. The wheels of the fore carriage are of such
diameter that they will pass under the frame.
The two bars a, a of the frame are held at the proper distance apart by means of
cross-bars, which, as shewn, are formed of angle iron.
9 is the oil tank which is placed between the bars a, a of the frame under the
engine, and is the water tank which is also placed between the said bars of the
frame and at that portion adjacent to the fore carriage is deepened, as will be
. clearly understood by reference to the drawings, so as to extend into the space
within the circle described by the wheels of the fore carriage when being locked,
so that the said deeper part of the tank shall not prevent the fore carriage wheels
from passing under the shallow part of the said tank. With this construction a
large tank capacity is obtained whilst the facility with which the engine can be
moved is not interfered with. These tanks g and h are supported upon the cross-
bars ff of the framing.
i is the cooling vessel or cooler which is mounted upon the framing over an
opening formed in the top of the tank h, the said cooling vessel having an open
bottem as shewn in Figure 3 and being supported at such height above the said
tank that air can pass between the bottom of the said cooling vessel and the tank
as indicated by the arrows. Within the said cooling vessel are supported several
tiers of boards i¹ edgewise, the boards of one tier being arranged crosswise of the
boards of the adjacent tier or tiers so as to break up or divide the water flowing
downwards through the cooling vessel as much as possible. The heated water
from the cylinder is lifted to the top of the cooler through a pipe k by means of a
force pump or the like and is delivered into a funnel whence the water flows
through a series of radiating arms m forming a tourniquet and is distributed over
the top tier of boards whence it trickles down over the several tiers into the
water tank to be again circulated through the cylinder jacket. It will be
understood that the water in its descent through the cooler meets an ascending
current of air which is preferably induced by the exhaust gases from the cylinder

page_text: being ejected from a nozzle n into a chimney or funnel o fixed on the top of the
cooler.
It will be noticed, by reference to Figure 3, that the open bottom of the cooler
is inclined downwardly and that the portion of the tank around the opening j is
somewhat depressed so as to form a kind of funnel to direct the cold water into the
tank. It will be understood that instead of arranging the cooler directly over the
opening j, it may be arranged in any other suitable position on the framing and
the water from the cooler directed to the water tank by means of a suitable
directing plate or channel.
p is a seat provided with a foot-board q arranged on the front of the framing for
the driver.
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 :-
1. The combination with an explosion engine mounted upon a travelling frame
or carriage, of a water carrying tank arranged between side bars of the same and
having that part immediately above and adjacent to the fore carriage deeper than
the other part thereof, substantially as described.
2. A carriage or mounting for an explosion engine comprising a framing
composed of channelled bars united by suitable cross-bars and supported upon
travelling wheels, an oil tank supported upon the said cross-bars of the frame
between the side bars, and a water tank also supported between the side bars and
having one portion thereof made deeper than the other, substantially as, and for
the purpose, described.
3. The combination with an explosion engine mounted upon a carriage provided
with tanks in the manner referred to in the preceding claiming clause, of a cooler
open at the bottom and placed so that the cooled water therefrom falls or is
directed into the water tank, a space being left beneath the bottom of the cooler
for the admission of an air current for cooling the water flowing down through the
said cooler, substantially as described.
4. The combination and arrangement of parts for rendering an oil engine
portable, substantially as herein before described and illustrated in the accom-
panying drawings.
