AN IMPROVED LUBRICATOR FOR STEAM-CYLINDERS, SLIDES AND THE LIKE
Year: 1885

page_text: I, GUSTAV CORRELL of Heckfield Villa, Crescent Road, in the liberty of Erleigh
in the County of Berks, Commercial Clerk, do hereby declare the nature of the
said invention for AN IMPROVED LUBRICATOR FOR STEAM-CYLINDERS, SLIDES
AND THE LIKE to be as follows:-
1
(The description will be well understood on reference to the accompanying
drawing.)
The lubricator is screw'd down on the Cylinder by the bolt A and consists of the
container B closed by the lid C. The container is drilled through its entire length,
forming on the upper part the tube E, which is enclosed by another tube D in
connection with the lid C. The tube D is loosely fitted over the tube E, allowing
the oil to rise from the container B (by capillarity) to the top of the tube E which
it enters. There is on the lower end of the tube E a little block or valve F resting
on the top of the regulating screw G. This valve allows the oil to flow down all
its circumference and to enter the screw through small groves on the bottom of it
and it thus allows the oil to enter the cylinder as long as there is no steam in it;
as soon as steam enters, it lifts up the valve F, shutting up the supply tube E
entirely. The lubricator consequently only oils the cylinder when there is no
steam in it; exactly what it is required to do, steam being itself a lubricant.

GUSTAV CORRELL, Heckfield Villa, Crescent Road in the liberty of Erleigh near
Reading, Berks, Commercial Clerk do hereby declare the nature of my invention
for AN IMPROVED LUBRICATOR FOR STEAM CYLINDERS SLIDES AND THE LIKE
a communication from H. Correll and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
This Lubricator consists of the Oil container B, closed by the lid C.-The lid
has two small holes drilled into it to keep up communication with the atmospheric
air and to allow the container B to be filled with oil without unscrewing the
lid C. The container is drilled through its entire length, forming on the upper
part the tube E which is enclosed by another tube D in connection with the lid C
and sieve I. The tube D is loosely fitted over the tube E to allow the oil to rise
between. In the centre of the lid C is the regulating screw H by which the flow
of oil can be regulated at the entrance of tube E. There is at the lower end of
the tube E the little block or valve F, resting on the screw G in the bolt A.-This
valve F allows the oil to run down in grooves all its sides. Round the bolt A
a thread is to be cut by means of which the lubricator is to be screwed unto the
cylinder or Slide box. On those Locomotive Engines however where the position
of the cylinders does not allow of the lubricator being fixed on the cylinder or
slide-box, it should be fixed to the engine as near to the cylinder as convenient
and the outlet screw G should be brought into communication with the cylinder
by means of a tube of small opening. On stationary engines without condenser
where the Lubricator is intended to oil the cylinder while the engine is working,
it should be fixed to one extreme end of the cylinder, so as to profit by the partial
vacuum behind the piston on the return stroke.
Whenever there is a vacuum or partial vacuum in the cylinder-and this is the
case in nearly all steam cylinders while working, but this vacuum is especially
noticeable in the cylinders of a locomotive running down hill or while approaching
a station with the steam shut off-the vacuum or partial vacuum causes the oil to
rise between the two tubes D and E by suction, assisted by capilarity, to flow down
the tube E, passed the valve F and to enter the cylinder through the hole in the
screw G.
As soon as steam enters the cylinder it lifts up the valve F and is thereby
hindered and prevented from escaping by the tube E.-In order to prevent the
flow of oil to be continuous and without suction a very small hole is pierced into
tube D near the lid C and consequently lubrication ceases when engine stops. This
lubricator is especially intended for Locomotive engines where it supplies a long
felt want, but it can also be applied with advantage on stationary Engines. The
reference letters A to I have reference to the drawing filed with the provisional
Specification.

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. That with this lubricator a slight partial vacuum will secure lubrication.
2. That it lubricates only when engine is going.
3. That on locomotive engines it lubricates at a time when such lubricating is
most important, namely when engine is going with the steam shut off.
4. That this lubricator as a whole is novel, being simple, sure and economical in
its action.
