IMPROVEMENTS IN LUBRICATORS
Year: 1885

page_text: I, GEORGE AUGUSTUS MOWER, of 21 Cross Street, Finsbury, in the County of
Middlesex, Mechanical Engineer, do hereby declare the nature of my invention for
"IMPROVEMENTS IN LUBRICATORS" to be as follows:-
My invention relates to lubricators of that class wherein a valve or plug is
arranged to be so adjusted that the oil will drop from the reservoir at longer or
shorter intervals; and my said invention is designed to improve the construction
and increase the efficiency of such lubricators.
2
An important feature of my said invention is the employment, in combination
with the valve or plug, of a spring which tends to close the same, and means
whereby the said valve can be adjusted to regulate the quantity of oil discharged
from the lubricator in a given time, and whereby the said valve can be readily
closed and opened without necessitating its re-adjustment.
•
My said invention, moreover comprises various improvements hereinafter set
forth.
My invention is conveniently and advantageously carried into practice as
follows, viz:-I provide a socket having a screw-threaded extension whereby the
lubricator may be secured in place. A glass reservoir is firmly secured to the upper
part of this socket by means of a metal tube, one end of which is screw-threaded
externally and is passed through a hole in the bottom of the reservoir and screwed
into the top of the said socket which is correspondingly screw-threaded internally.
The said tube is provided with a collar or flange which, when the parts are property
fitted, bears against the interior surface of the reservoir. In the lower part of the
said tube, a conical seating is formed to receive the valve or plug, which is of
conical shape. One or more holes is or are bored transversely in the said tube
above the said seating and above the aforesaid collar or flange to permit the dis-
charge of oil from the reservoir when the valve is open. The said socket is
preferably open on two opposite sides so that the oil can be seen as it drops from
the end of the tube.
The valve or plug is provided with a spindle which is inserted in, and extends
through, a hollow screw-bolt whereby the lid or cover is held or secured upon the
reservoir. This bolt is passed through a hole in the cover and is screwed into the
upper end of the aforesaid tube, thereby firmly securing the said cover in place.

page_text: A spiral spring is placed upon the valve-spindle. One end of this spring bears
against a shoulder on the valve-spindle, and the other end thereof fits into a recess
or cavity in the said screw-bolt.
An adjusting screw is fitted in the upper end of the said screw-bolt, and is
provided with a lock-nut. The valve-spindle extends through this adjusting
screw, and a cam or cam-lever is connected with the said spindle by a hinge-joint
above the said screw. The said cam or lever is held by the aforesaid spring,
against the top of the adjusting screw, and is so formed that it can be turned on
its hinge or pivot and when it is in line with the said spindle it will act as a cam
to compress the said spring and lift the valve, and, when turned into a position
at right angles to the axis of the spindle, it will permit the spring to expand and
depress the valve.
The discharge of oil from the lubricator is regulated by turning the said
adjusting screw in one direction or the other and thereby increasing or diminishing
the extent of opening of the valve. When the valve is properly adjusted and the
cam-lever is in its vertical position, the said valve can be closed, if necessary or
desirable, by turning the said cam-lever into a horizontal position, and can be
again opened by turning it back into the vertical position, without affecting the
adjustment of the valve by the aforesaid screw. The said cam-lever, moreover,
serves as a signal or indicator to show whether the valve is open or closed. If it
is desired that a considerable quantity of oil should be rapidly discharged from the
lubricator (for example, when a bearing becomes hot), the valve can be opened to
its full extent by pulling the cam-lever and valve-spindle upward and thereby
compressing the spring and lifting the valve.
The lid or cover of my lubricator is made of a shape resembling that of a saucer,
that is to say, it has a raised or turned up edge or rim, and an aperture is formed
in it through which oil may be poured into the reservoir. The said lid or cover,
by reason of its peculiar shape, prevents waste of oil in case of its being poured on
the cover at one side of the said aperture as it will then flow towards, and through,
the said aperture and into the reservoir.
I sometimes fit upon the aforesaid screw-bolt a plate, which, when properly
adjusted, will close the said aperture in the lid or cover. This plate is formed
with two shoulders or projections at an angle of ninety degrees to each other, or
nearly so, and is secured to, or held down upon, the cover by a screw inserted
therein, which screw also serves, in combination with the shoulders on the said
plate, to limit the movement of the latter in either direction.

page_text: I, GEORGE AUGUSTUS MOWER, of 21. Cross Street, Finsbury, in the County of
Middlesex, Mechanical 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 :-
My invention relates to lubricators of that class wherein a plug or valve is
arranged in combination with an oil reservoir and is designed to be so adjusted
that the oil will drop from the said reservoir at longer or shorter intervals; and
the object of my said invention is to improve the construction and increase the
efficiency of such lubricators.
An important feature of my said invention is the employment, in combination
with the valve, of means whereby the same can be readily opened and closed at
any time without altering or affecting the adjustment thereof, or necessitating its
re-adjustment, with respect to the regulation of the flow or discharge of oil from
the lubricator when opened.

My said invention, moreover, comprises various improvements hereinafter set
forth.
In the accompanying drawing, I have shewn how my said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a vertical central section.
Figure 2 a side elevation, and
Figure 3 a plan, of a lubricator constructed according to my said invention.
Like letters indicate corresponding parts throughout the drawing.
a is a reservoir of glass or other suitable material, for containing the oil. This
reservoir is fitted into a socket b¹ at the upper end of a hollow stem or standard b,
a leather ring or washer 62 or other suitable packing being placed between the said
reservoir and the socket 6. The said reservoir is secured to the stem or standard b
by means of a metal tube c, the lower end of which is screw-threaded and is passed
through a hole in the bottom of the reservoir a and screwed into the top of the
stem or standard b. The said stem or standard is provided with a screw-threaded
extension 63, whereby the lubricator may be secured in place on the bearing or
other part to be lubricated. The tube c is provided with a collar or flange c' which
bears against the inner surface of the reservoir a. In the lower part of the said
tube, a conical seating c² is formed for, the taper plug or valve d. One or more
holes ca are bored transversely through the said tube above the seating c² and
above the collar or flange c, to permit the flow or discharge of oil from the reservoir
when the valve is open. The stem or standard b is preferably formed with openings b
on opposite sides thereof, as shewn, so that the oil can be seen as it drops from the
end of the tube a

page_text: The plug or valve d is provided with a spindle d, which extends through a
hollow screw-bolt e whereby the lid or cover f is held or secured upon the
reservoir a. This bolt is passed through a hole f¹ in the cover f, and is provided
with a stud or projection e¹ which fits into a notch f¹ in the cover f and thus
prevents rotation of the said bolt. The upper end of the tube c is screwed like
a nut upon the end of the screw-bolt e, thereby firmly securing the cover f in
place.
A spiral spring g is placed upon the valve-spindle d' and within a recess or
cavity e² in the screw-bolte. One end of this spring bears against a shoulder d³
on the said spindle, the other end thereof bears against the end of the said recess
or cavity in the screw-bolt.
A hollow or tubular adjusting screw h is fitted in the head or upper end of the
screw-bolt e, and is provided with a lock-nut h¹. The valve-spindle d extends
through this adjusting screw, and a cam or cam-lever i is pivotted at ¹ to the said
spindle above the head h² of the screw h. The cam or lever i is so formed that the
turning of the same on its hinge or pivot from the position shewn by dotted lines
in Figure 2 into the position shewn by full lines in this figure, will cause the
compression of the spring g and the opening of the valved to a greater or less
extent according to the adjustment of the said valve by the screw h. The flow or
discharge of oil from the lubricator can, therefore, be regulated by turning the said
screw / in one or the other direction and thereby increasing or diminishing the
extent of opening of the valve. The said screw can be securely held or locked,
in any position to which it may be adjusted, by screwing up the nut h¹ against the
head of the screw-bolt e.
When the valve is properly adjusted and the cam-lever i is in its vertical
position, the valve can be closed, if necessary or desirable, by simply turning the
said lever into the position shewn in dotted lines in Figure 2, and can be again
opened by turning the said lever back into its vertical position, and the opening
and closing of the valve can be thus effected without altering the adjustment of
the valve by the screw h, or Decessitating its readjustment. The extent of this
adjustment should be limited so that the valve cannot be kept open by the
adjusting screw h when the lever i is in its horizontal position. The lever i serves
as a signal or indicator to show whether the valve is open or closed. If it is
desired that a considerable quantity of oil should be discharged from the lubricator
in a short space of time (for example when a bearing becomes hot), the valve can
be opened to its full extent by pulling the cam-lever i and valve-spindle d' upward
and thereby compressing the spring and lifting the valve.
The lid or cover f of my lubricator is made of a shape resembling that of a
saucer, that is to say, its upper side is more or less concave and it has a raised or
turned up edge or rim f³. An aperture f4 is formed in the said cover, through
which oil may be poured into the reservoir. The said lid or cover, by reason of its
peculiar shape, prevents waste of oil in case of its being poured on the cover at one
side of the said aperture, as it will then flow towards and through the said aperture
and into the reservoir,
I sometimes fit upon the screw-bolt e a plate k which, when properly adjusted,
will close the said aperture in the lid or cover. This plate is held in place by a
shoulder es on the said bolt and is formed with two shoulders or projections /¹,
which act, in combination with a screw or stud / fixed in the cover f, to limit
the movement of the said plate. This plate serves as a sliding cover to close the
aperture ft.
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
Tn

purpose, specified.
Second. The cap or cover concave at its upper side and provided with an
aperture closed by a pivotted plate, substantially as, and for the purpose, set
forth.
Third. The improved lubricator consisting of the parts constructed and combined
substantially as described with reference to the accompanying drawing for the
purpose specified.
