PROVISIONAL SPECIFICATION.
Improvements in Lubricators for use in connection with Gas, Oil, or
other Explosion Engines, and similar purposes.
We, JONATHAN DAVID NOBLE, of Coronation Road, Bristol, Engineer, and
EDWARD BRICE, of Berkeley Road, Bishopston, Bristol, Brass-founder do hereby
declare the nature of this invention to be as follows:-
Our invention relates to an improved sight-feed lubricator, specially constructed
for use in connection with gas, oil, or other explosion engines, and for other purposes
where a uniform lubrication is required.
In lubricators used for the cylinders of steam engines, the necessary quantity of
water for conveying the oil to the top of the reservoir or container and floating it
in the required direction, is usually obtained by condensing steam from the boiler
or engine, but with gas and similar engines which have no steam for condensation,
other means have to he employed for obtaining the water supply; and the body
of the container in which the oil is placed, is usually made of metal, which
necessitates the use of gauge glasses to indicate the quantity of oil in the container;
instead of the body being made of metal, we propose, to use glass, which will
enable the attendant to observe more readily whether the container is supplied with
the necessary quantity of oil.
To carry our invention into effect, we tap the water jacket of the engine where
convenient, and insert a small tube, by means of which a supply of water is
conveyed to the lower part of the container; or if the water jacket is not available,
the tube may be connected to the circulating pipe or water cistern, and the water
flow therefrom to supply the lubricator, like condensed steam flows into the
lubricators of steam engines. In making the container or body of the lubricator,
we provide a glass cylinder of any suitable size and length, securely fitted with
metal ends, thus rendering the whole body of oil in the container visible at all.
times and from any direction, which enables the gauge glasses now used to be.
dispensed with; from the metal ends of the container, the necessary fittings project.
to carry the sight glass or tube of water, through which the lubricant flows to the
aperture leading to the cylinder or other places to be lubricated.

COMPLETE SPECIFICATION.
Improvements in Lubricators for use in connection with Gas, Oil, or
other Explosion Engines, and similar purposes.
We, JONATHAN. DAVID NOBLE, of Coronation Road, Bristol, Engineer, and
EDWARD BRICE, of Berkeley Road, Bishopston, Bristol, Brass-founder 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 :---
i
.
Our invention relates to improvements in sight feed lubricators, specially con-
structed for use in connection with gas, oil, or other explosion engines, and for.
bearings, mills, and other purposes where a uniform and continuous lubrication is
required.
The improvements in our lubricators consist principally (1) in using glass for the
oil reservoirs or containers, whereby the gauge glasses are dispensed with, and the

page_text: attendant is enabled more readily to ascertain the quantity of oil in the container;
(2) in obtaining a water supply from a cistern or any other available source, instead
of being dependent on condensed steam from a boiler; and (3) in making such
arrangements at the outlet from the container, that several feeds may be kept in
operation from one lubricator at the same time, the supply to each being regulated
according to the requirements of the engines or bearings to which the oil may be
conducted.
Our improved lubricators operate on the displacement principle, and are con-
structed in the following manner :-A. glass cylinder of any suitable size is provided,
securely fitted and packed in metal ends, in which the appliances for supplying oil
and water are also fitted, thus forming the reservoir or oil container; one or more
feed glasses are also arranged by the side of the cylinder, and connected thereto by
the usual bearings and channels, the latter terminated by regulating valves, by
which the quantity of oil to be used is allowed to pass, one globule at a time, into
the feed glasses and thence by gravitation to the engines or machinery to be
lubricated; the outlet at the bottom of the container is fitted with one, two, or
more channels through which the oil flows to the regulating valves of the feed glasses;
instead of using condensed steam for supplying the water and pressure for floating
the oil to its destination, the water may be obtained from the jacket or circulating
pipe of a gas engine, or where this is not available, from a cistern or the ordinary
water service, so that the lubricator may be fixed at any convenient distance from
the engine or machinery, and the oil conducted thereto by pipes attached to the
outlets from the feed glasses.
Our invention will be more fully understood by reference to the accompanying
drawing, which represents a lubricator, partly in elevation and partly in section,
with one feed glass on each side; but as before mentioned, it may be made with
one or any suitable number of feeds, each having its own regulating tap or
valve-
A is a glass cylinder, at each end of which a metal cap B is fitted with rubber
or other packing to make it tight; C, C, are arms or brackets attached to the
caps, forming supports for the cylinder and feed glasses; D is the filling plug to
be removed from the cup d when the oil is poured into the cylinder; E is an air
vent plug, to be open when filling the cylinder with oil or discharging the water
therefrom before refilling; F is a tube through which the water is supplied to the
cylinder and feed glasses, controlled by the tap G; H is a metal tube fixed in the
caps of the cylinder, having a hole h near the top for admitting oil, and an outlet
at the bottom through which the oil passes by means of the channels I to the feed
glasses, the quantity admitted being regulated by the valve K and a conical plug k
which engages in the bottom of the tube L, whence the oil escapes in globules
through the feed glass M and valve m to the outlet pipe N, and thence by tubing
to the engine or machinery to be lubricated; O is an outlet pipe for the water
which has accumulated in the cylinder while the oil has been distributed through
the feed glasses.
The various parts of our lubricator being provided and fitted together as
described and shown in the drawing, it is put into operation in the following
manner A suitable place being selected in which the lubricator is to be fixed, a
pipe is brought from the cistern or other source from which the water supply is to
be obtained, care being taken that the cistern is sufficiently high to give the
pressure necessary to convey the oil to any bearings or machinery that may be
above the level of the lubricator; a socket or tee piece is attached to the pipe, of
sufficient strength to receive the lubricator and maintain it in a vertical position;
the shank or water inlet is then inserted in the socket, and connections made
from the outlets N to the parts requiring lubrication the cylinder and feed
glasses are first filled with water, which is done by opening the stop cock G, setting
the pointer downwards or towards the water inlet, the water will then flow into
the cylinder A, through the tube II to the channels I, and by opening the regulating
valves K, the feel glasses M will also be filled; this being done, the valves are
:

page_text: closed and the water retained in the feeds; the pointer is then turned towards
the drip outlet O, the vent plug E opened, and the water left in the cylinder will
be discharged through the outlet; the pointer is then turned upwards, which closes
the stop cock, the plug D is removed and the oil poured through the cup d into
the cylinder, when it is filled, the plug D is restored to its place, the air vent E
closed, and the lubricator is ready; then by turning the pointer downwards, the
stop cock will be opened, and the pressure of the water will operate on the oil,
causing it to flow towards, the regulating valves, and by opening one or more of
these, the oil will pass through the tubes L, M, and N, in whatever quantities may
be required, to the parts of the engine or bearings to be lubricated.
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 construction of lubricators on the displacement principle with glass con-
tainers, whereby the quantity of oil therein can be more readily seen by the
attendant, and the gauge glasses hitherto used for this purpose may be dispensed
with.
2. The construction of lubricators with appliances whereby the water used for
displacement and floating the oil may he obtained from a cistern, from the service
mains, or from any other source yielding pressure, substantially as herein set forth
and described.
3. The combination of well known mechanical arrangements in the construction
of our improved lubricators with glass containers and independent water supply,
substantially as and for the purposes herein described and set forth in the accom-
panying drawing.
