IMPROVEMENTS IN LUBRICATORS
Year: 1884

page_text: I, JONATHAN DAVID NOBLE, of the City and County of Bristol, Engineer do
hereby declare the nature of the said invention for " IMPROVEMENTS IN LUBRICATORS"
to be as follows:-
::
This Invention which relates to improvements in lubricators, consists in applying
what is known as a "sight feed "to that class of lubricators known heretofore as
close top lubricators. The same being specially applicable to "Clements Patent
.Economic Lubricator" for the purpose of enabling the operator to see the exact
quantity of suet, oil, tallow or other lubricant being used at any time, and for
adjusting or regulating the quantity thereof.
In carrying out these improvements, as represented partly in elevation and
partly in section on the accompanying drawing, an opening a, is made in the lower
part of the side of the body or reservoir b, of the lubricator, leading into an annular
space c, formed in a vertical branch piece d.-This branch piece d, is provided at
its upper part with a screw-down or other adjustable valve e, the seating of which
is immediately over a hollow conical nozzle f, whose largest diameter is uppermost.
Around this conical nozzle f, is provided a glass tube g, suitably fitted into the
tunderside of the branch piece d, and the lower end of which is fitted into a
horizontal branch pipe h, leading into the vertical tube i, at the lower part of the
lubricator. This vertical tube i, is provided with the valve j, by means of which,
the oil or tallow or other lubricant contained in the lubricatór, is allowed to pass
into the cylinder or valve chest or other part of a steam engine or its connections
to which the said lubricator is attached.
In operation, the supply of oil, or tallow or other lubricant passing out of the
reservoir, is regulated by means of the screw-down or other adjustable valve e,
above the inverted conical nozzle f, herein-before mentioned. It then passes from
the said conical nozzle f, into the branch pipe h, connected with the apparatus: to
be lubricated, and it may be seen when passing from the said conical nozzle f
through the glass tube g, surrounding the same.

page_text: I, JONATHAN DAVID NOBLE of the City and County of Bristol, Engineer do
hereby declare the nature of my said invention for IMPROVEMENTS IN LUBRICATORS
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My Invention, which relates to improvements in lubricators, consists in applying a
a "sight feed" to that class of, lubricators known heretofore as close top lubricators,
the same being specially applicable to." Clement's Patent Economic Lubricator."
for the purpose of enabling the operator to see the exact quantity of suet oil, tallow
or other lubricant being used at any time, and for adjusting or regulating the
quantity thereof.
In carrying out these improvements, an opening is made in the side of the body
or reservoir of the lubricator, leading into a vertical branch piece. This branch
piece is provided at its upper part with a screw-down or other adjustable valve,
the seating of, which is immediately over a hollow conical nozzle whose largest
diameter is uppermost. Around this conical nozzle is provided a glass tube suitably
fitted into the underside of the branch piece, the lower end of which tube is
similarly fitted into the upper side of another branch piece leading into the vertical
branch at the lower part of the lubricator.
This last named vertical branch is provided with a valve by means of which, the
oil, tallow or other lubricant contained in the lubricator, is allowed to pass into the
cylinder or valve chest or other part of a steam engine or its connections or other
apparatus to which the said lubricator is attached.
In operation, the supply of oil, or tallow or other lubricant passing out of the
reservoir, is regulated by means of the screw-down or other adjustable valve above
the inverted conical nozzle herein before mentioned. It then passes from the said
conical nozzle into the branch pipe connected with the apparatus to be lubricated,
and it may be seen when passing from the said conical nozzle, through. the glass
tube surrounding the same.
In order that my said invention may be most fully understood and readily
carried into effect, I will proceed to describe the drawings hereunto annexed..
The annexed Figure of Drawing represents partly in side elevation and partly in
vertical section a lubricator constructed according to my present Invention.
In carrying my present Improvements into practice, I form the opening a,
through the side of the body or reservoir b. To the inner surface of the reservoir b,
at the opening a, I provide the horizontal tube c, into the inner end of which the
vertical tube d, is secured. To the outer surface of the reservoir b, at the opening a,
I provide the space formed in the vertical branch piece e. This branch piece e, is
fitted at its upper part with the screw-down or otherwise adjustable valve f, the
seating of which is immediately over the hollow conical nozzle g, the largest
diameter of which is uppermost. Around the conical nozzle g, I provide the glass
tube h, which is suitably fitted by the glands i, the upper end, into the under side
of the branch piece e, and the lower end into the horizontal branch j.-The branch j,
is connected with the vertical branch k, by which the lubricator communicates
:

page_text: with the cylinder or valve chest or other part of a steam engine or other apparatus
to which the said lubricator is attached. The vertical branch k, is provided with
the valve, by means of which, the oil, tallow or other lubricant contained in the
lubricator is allowed to pass into the portion of apparatus to which it is attached.
In operation, the supply of lubricating material which is initially charged into
the reservoir b, through the opening m, left clear by the removal of the screwed
plug n, passes out through the opening a, and down through the hollow conical
nozzle g. The dropping of the lubricating material may then be seen through the
glass tube h, as represented upon the annexed drawing, and after falling into the
branch j, the said material passes down the vertical branch k, direct to the parts to
be lubricated. The quantity of lubricant dropping through the nozzle g, is regulated
by the position of the valve f,'relatively with its seat.
The portions of the apparatus shewn upon the annexed drawing and not herein-
before described, being well known, need not be herein further referred to.
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
"
Improvements in Lubricators consisting of the branch piece e, valve f, hollow
conical nozzle g, glass tube h, and branch pipe j, all constituting the "sight feed
herein before described and operating substantially as hereinbefore set forth with
reference to the annexed drawing.
