Improvements in Water Cooling and Circulating Apparatus for
Explosion Engines, specially suitable for Use on Motor Cars.
I, ERNEST ESTCOURT, of 23, Compayne Gardens, South Hampstead in the.
County of London, no occupation, do hereby declare the nature of this invention
to be as follows:-
This invention relates to water cooling apparatus for explosion engines of
the type having a jacketed cylinder which is kept cool by water circulating there-
through. In such engines as heretofore arranged the water is usually pumped
through the circulation pipes, and jacket, and the object of this invention is
to arrange a system of circulating pipes in connection with the cylinder in such
a way as to produce a more effective circulation and cooling of the water without
the aid of pumping machinery and to arrange cooling pipes in such a manner
that the water is effectively cooled by the atmosphere.

According to this invention the engine is fitted with a number of water pipes
above and below the cylinder opening into upright conduits at each end.
of these conduits is blocked at about its centre, and the upper part is provided
with a funnel shaped pipe leading into the lower part of the upright conduit.
It is also provided with an upper transverse conduit which is connected on one
side by a pipe from one of the upright conduits and on the other side by a pipe
opening into the funnel shaped pipe so as to separate the water that is taken
up by the steam and to pass into the lower part of the other conduit below the
block through the said funnel shaped pipe.
A small pipe opens into the interior of the upper part of the upper transverse
conduit to allow of the overflow of water or the escape of steam into the atmos-
phere.
Three pipes connect the system into the lowest part of the cylinder jacket;
one leading from the lowest part of the system into the lowest part of the
cylinder jacket, the second from the top of cylinder into the upper part of the
blocked upright conduit, and the third from the opposite side of the top of the
cylinder into a lower horizontal conduit closed at one end and opening into the
upper part of the blocked conduit at the other end.

_
This invention relates to water cooling apparatus for explosion engines of
the type having a jacketed cylinder which is kept cool by water circulating there-
through. In such engines as heretofore arranged the water is usually pumped
through the circulation pipes and jacket, and the object of this invention is
to arrange a system of circulating pipes in connection with the cylinder in such
a way as to produce a more effective circulation and cooling of the water without
the aid of pumping machinery and to arrange the cooling pipes in such a manner
that the water is effectively cooled by the atmosphere.
In the accompanying drawings Fig. 1 is a sectional elevation showing my
invention as applied to an explosion engine of the "Daimler" type, and Figs. 2
and 3 are respectively perspective view and sectional side elevation of a motor
carriage showing applied thereto, and on a reduced scale, the engine and con-
nections shown in Fig. 1. Fig. 4 is an enlarged section taken on the line 44
of Fig. 1.
According to this invention the engine is fitted with a number of water cir-
culating pipes A above and below the cylinder B and opening into upright
conduits CD at each end. One of these conduits, in the drawings the conduit C,
is blocked at about its centre by a partition C. In the upper part of this
blocked conduit C is a funnel shaped pipe E the lower end of which opens in
the lower part of the blocked conduit just below the partition C', the upper end
being connected to the underside of an upper transverse conduit F, the other
end of which conduit Fis, by means of a short pipe G, in open communication
with the other upright conduit D. By this arrangement any water carried
through the system by the steam generated therein, will be trapped in the upper
transverse conduit F and carried by the funnel E to, and deposited below the
partition C in the upright conduit C. The steam will meanwhile be collected
in the central enlargement or dome of the conduit F, into the upper part of
which opens one end of a pipe H, whose lower end discharges outside the
apparatus, thus allowing of the overflow of water or the escape of steam into the
atmosphere.
In the lower part of the upright conduit D is a weighted plunger D¹ loosely
fitting the interior of the conduit D and supported on a spiral or other spring d¹
so as to be always above the level of the uppermost a of the lower series of water
circulating pipes A (see Fig. 4). d is a flange or projection on the interior of
the conduit D to form a seat to receive the weighted plunger D' in the event of
the supporting spring breaking or compressing, so that in no case can the
plunger block up the openings of the adjacent ends of the pipes A.
plunger 1 is made conical or tapering at its upper part D2 and has a way or
ways therethrough for the passage of water and is fitted with a valve d² opening
downwards.
This
The plunger is fitted fairly loosely in the interior of the conduit D and is free
to move up and down therein by the vibration set up either by the working
parts of the motor, or by the jolting of the vehicle, if fitted to one, when travel-
ling over rough roads. As the plunger moves upwards the water above it will
be displaced with little friction by the conical or tapering top D2 and the valve d³
will open downwards allowing the displaced water to pass to the underside of
the plunger ₁. As the plunger moves downwards the valve will close and the
plunger will then act on the surface of the water forcing it downwards to the
open ends of the pipes A. In this way I utilize the vibration inherent in every
explosion engine to assist in promoting the circulation of water in the pipes.
Three pipes, J, K. and L, connect the system with the cylinder jacket M.
pipe J, leads from the lowest part of the system into the lowest part of the
cylinder jacket M; the second pipe K, leads from the top of the cylinder jacket
into the upper part of the blocked upright conduit C; and the third pipe, L,

page_text: leads from the opposite side of the top of the cylinder jacket into a lower hori-
zontal conduit N the ends of which pass through the sides of the upright con-
duits C and D the end n inside the conduit Ď being closed, while the other
end n' is open.
The circulation of the water in the apparatus will now be understood. The
water becoming heated will flow through the pipes K and L into the conduit C
above the partition C¹, thence through the upper series of water pipes A to the
upright conduit D and down through the latter to the lower series of water
pipes A, thence into the lower part of upright conduit C, and through the pipe J
back to the cylinder jacket M.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
(1) Water circulating apparatus for explosion engines, comprising a series
of water circulating pipes above and below the cylinder jacket opening into
upright conduits one of which is blocked, a transverse conduit connecting the
upper ends of said upright conduits and having a funnel tube on one end passing
into the lower part of the blocked upright conduit, with means for allowing
the escape of surplus water and generated steam and for trapping the water
carried by the steam, and pipes connecting the cylinder jacket to the water
circulating system, all arranged substantially in the manner and for the pur-
pose herein before described and illustrated in the accompanying drawings.
(2) The arrangement of a series of water circulating pipes exposed to the
atmosphere and connected to the interior of the cylinder jacket of an explosion
engine substantially in the manner and for the purpose hereinbefore described
and illustrated in the accompanying drawings.
