the Closed Crank Chambers of Quick Running Engines, and
for Indicating the Level of Liquid in such Chambers.
I PETER WILLIAM WILLANS of Thames Ditton in the County of Surrey Engineer
do hereby declare the nature of this invention to be as follows:-
In order to be able to ascertain readily the height of the lubricant in the closed
crank chambers of quick running engines I lead off a pipe from the lower part of
this chamber to a closed receiver. A pipe is made to descend down from the top
nearly to the bottom of the receiver and through it liquid can pass upwards to a
cup above it this cup may be of glass if desired so that the height of liquid can be
seen through its sides or it may simply be open at the top so that the height of
liquid can be ascertained by looking down into it.
The lubricant usually consists of oil and water and these get mixed together
being dashed about by the cranks but any oil passing from the crank chamber
with the water into the receiver above mentioned separates from the water and
floats upon its surface so that practically water only rises up from it into the
gauge cup.
At a suitable height in the cup I lead away a waste pipe so that if the water in
the crank chamber is too high it flows away leaving the oil behind it and so cold
water may be kept running into the crank chamber whilst hotter water flows off
through the waste pipe.
The pipe which enters the receiver or separator from the crank chamber enters
it at a point some distance from the top so that the part of the receiver above
where the pipe enters acts as an air vessel, and prevents violent splashing up the
central pipe.
The above, described way of forming the gauge is applicable to all engines in
which the crank shaft runs in a chamber partially filled with oil and water.

I PETER WILLIAM WILLANS of Thames Ditton in the County of Surrey Engineer
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 :-
In order to be able to ascertain readily the height of the lubricant in the closed
crank chambers of quick running engines I lead off a pipe from the lower part of
this chamber to a closed receiver. A pipe is made to descend down, from the top
nearly to the bottom of the receiver and through it liquid can pass upwards to a
cup above it, this cup may be of glass if desired so that the height of liquid can be
seen through its sides or it may simply be open at the top so that the height of
liquid can be ascertained by looking down into it.
The lubricant usually consists of oil and water and these get mixed together
being dashed about by the cranks but any oil passing from the crank chamber
with the water into the receiver above mentioned separates from the water and
floats upon its surface so that practically water only rises up from it into the
gauge cup.
:
At a suitable height in the cup I lead away a waste pipe so that if the water in
the crank chamber is too high it flows away leaving the oil behind it and so cold
water may be kept running into the crank, chamber whilst hotter water flows off
through the waste pipe..
The pipe which enters the receiver or separator from the crank chamber enters
it preferably at a point some distance from the top so that the part of the receiver
above where the pipe enters acts as an air vessel and prevents violent splashing
up the central pipe.
The above described way of forming the gauge is applicable to all engines in
which the crank shaft runs in a chamber partially filled with oil and water.
The drawing annexed shows a vertical section of the lower part of the closed
crank chamber of a quick running steam engine and of apparatus constructed in
the above described manner used in connection with it.
A is the crank chamber.. B a pipe leading from the lower part of this chamber
to a closed receiver C entering it at a point at a, distance above the bottom-and
preferably, also as above stated at a point some distance from the top so that the
upper part may act as an air vessel-but this is not essential. D is a cup above
the top of the closed receiver-E a pipe descending from the cup nearly to the
bottom of the receiver -F an overflow from the cup. G a funnel through which
oil can be supplied to the crank chamber. Water may also be allowed to flow
constantly into the funnel-it passes away by the overflow F leaving the oil in
the chamber. Any oil collected in the receiver may from time to time be drawn
off from it by unscrewing the plug.H at the bottom.

page_text: 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. Leading off a small pipe from the lower part of the crank chamber of quick
running steam ongines to a point some distance from the bottom of a closed
receiver from the lower part of which a pipe is led up to a cup in which the level
of the liquid may be seen.
2. The means substantially as herein before described and illustrated in the
drawing annexed for permitting of a stream of water being passed through the
closed crank chamber of quick running engines and for indicating the level of
liquid in such chambers.
