JOHN ETHERINGTON, Consulting & Inspecting Engineer & Sole Manufacturer
& Refiner of Cylindrine lubricating Oils, 39a King William Street, London
Bridge, London EC do hereby declare the nature of my invention for IMPROVE-
MENTS IN AUTOMATIC SIGHT FEED LUBRICATOR FOR FEEDING THE LUBRICANT TO
VALVES & CYLINDERS, OF STEAM, WATER, GAS, OR ANY OTHER KIND OF ENGINE-
against any pressure or superheated steam and can be applied to any part or
portion of the Engines or Machinery, and one Lubricator will feed the lubricant
to, one or Six Engine Cylinders or valves as the case may be.
The Lubricator consists of two or more Cylindrical reservoirs & one or more
glass Cylinders, the steam is admitted by piping overhead into a reservoir or
condenser, as the case may be, and condensed then admitted into the bottom of the
Oil cylinder or reservoir, forcing the Oil & causing the same to pass down tubes,
then out at arms or connections, passing up the glass cylinders in visible drops,
thence to the Cylinders, valves or Steam pipes or main bearings.
The valves for filling are so arranged with cups and hollow spindles with port
holes & white metal seatings so that they can easily be filled when a ship is rolling,
at sea, without being taken apart, by only slacking back the valves, and a cup and
valve is provided on the top end of the condenser or reservoir under the same
construction as the former to supply the condenser or reservoir with clean water
when working under Superheated Steam to keep up the displacement or feeds of
the Oil to the working parts of the machinery, therefore running short of water for
displacement is avoided in all cases, there is also a small valve addopted at the
bottom of the Oil reservoir to draw off the water for refilling with Oil.
One double Lubricator will feed four Engine Cylinders or into main Steam pipes
by the introduction of a T piece made in the form or shape of a V, with a V shape
partition inside for dividing the lubricant equally to each Engine.

page_text: JOHN ETHERINGTON, M.I.M.E. Consulting and Inspecting Engineer 39a King
William Street London Bridge London E.C. 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 :-
My Invention relates to that class of Lubricator, known as the Double "Auto-
matic" Sight Feed Lubricator, or Lubricators this said Lubricator or Lubricators is.
especially designed for Marine or Stationary Engines, into which steam or water of
Condensation is admitted to cylindrical chamber or Oil reservoir to expel the oil
from the said chamber.
The principle object of my Invention is to furnish a means whereby the amount
of oil may be regulated, and the outflow of which may be observed and ascertained
this said Lubricator or Lubricators will feed-against any pressure or in any position,
and can be applied to any part or parts of Engines and Machinery, this said
Lubricator or Lubricators will feed the Lubricant to one or six Engines or Valves,
as may be required.
Such being the nature and object of my said Invention, I will now proceed to
describe in detail the manner in which the same is to be or may be performed, and
in order that the same may be clearly understood, I have annexed hereunto a
Sectional Drawing Illustrative thereof and have marked the same with letters of
reference corresponding with same.
A is a cylindrical chamber or Oil reservoir into which oil is admitted through D.
for which a special cup has been placed thereon. In this said cylindrical chamber
or oil reservoir A, there is a tube A² passing down centre of same, through which
the Lubricant is forced down through passages L. L. by the pressure of condensation
or by the Specific Gravity of water (before refilling this said cylindrical chamber
or oil reservoir, the water of condensation must be drawn off, and this I have
effected by means of a bib drainage outlet) and by valves G. H the manipulation of
the said Lubricator or Lubricators may be accurately regulated as the feed is one
of oil rising by Spisific Gravity through columns of water C1 C2 which being of
lighter Specific Gravity than the water floats to the top of same, and flows by
passages E and F to the steam pipe valve chest or other places where the
Lubricant may be required. I have so constructed the manipulation_of_the_said
Lubricator or Lubricators as to do away with all check valves. Referring to
Figs. 1 and 2 by having the so called check valves F. F. in the form or shape of a
sluice with a well seating of sufficient length, and at right angles to each other, so
that the pressure of steam as it passes along passages E2 F 2 when it gets to the
ends of the said passages, its own pressure checks its self against end of passages E¹
and F¹ so that the more pressure that there is in passages E2 and F2 the less back
pressure there is upon the Glass or Glasses of the said Sight Feed Lubricator or
Lubricators Refearing to Figs. a 1. b 2. c 3. and E* I have especially designed cups
for refilling same thereon working within them B. D. C. wheel valves with hollow
spindles with port holes and white metal seatings, so that they can be easily filled
when the ship is rolling, without being taken apart by only slacking back the said
valves.

page_text: J is condenser secured to the bottom of the said cylindrical chamber or oil
reservoir A. with a valve B for the manipulation of condensation. b is a valve
through which steam is admitted from steam pipe or Boiler (as the case may be) to
the said condenser of same when the valve J is opened the steam or condensation
or both are free to enter the said cylindrical chamber or oil reservoir to force the
oil out of the said chamber A. by way of oil passages L. L on the top end of
condenser or reservoir is a cup E¹ of the same construction as B. C. to supply the
said condenser or reservior with water when working under superheated steam, to
keep up the displacement of oil or feed of oil to the working parts of machinery or
Engines (as the case may be) therefore running short of water for displacement of
oil is avoided in all cases.
The said Lubricator or Lubricators are workable without the use of any
mechanical appliances whatsoever, they embrace simplicity of construction mani-
pulation and operation.
Having now particularly described and ascertained the nature and object
of my Invention, and in what manner the same is to be or may be performed,
I declare that what I claim is as follows
Firstly. In a Sight Feed Lubricator or Lubricators the combination with the
cups adapted for the purpose of refilling as specified.
Secondly. In a Sight Feed Lubricator or Lubricators the combination with cup
on condenser for supplying the same with water when working under superheated
steam as specified.
Thirdly. In a Sight-feed Lubricator or Lubricators, the valves G H for the
manipulation & regulation of the feeds as specified.
Fourthly. In a Sight feed Lubricator or Lubricators, the check valves in the
form or shape of a Sluice with a well seating as specified.
Fifthly. In a Sight feed Lubricator or Lubricators, for the construction and
manipulation of feeding from three to six feeds, as specified.
