Improvements in Lubricators.
I DAVID NOWELL, of 20, Charles Street, Bradford, in the County of York,
Consulting Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to novel and useful improvements in lubricators for rotary,
reciprocatory and analogous bearings, such as loose pulleys, connecting rods, or other
bearings subject to rotation, agitation or vibration; and its object is economy in the
use of lubricants, by employing a lubricator of improved construction adapted to
uniformly feed or distribute the lubricant to such bearings without waste, the amount
distributed being capable of adjustment.
The improved lubricator consists of a shell or casing of suitable form, attached to
the bearing by means of a tube or perforated projection on the base. The said tube
or projection is screwed, or otherwise adapted for securing the lubricator to the
bearing, which means of attachment may be supplemented by passing small screws
through lugs on the shell into the bearing, or by twisting wire round the bearing
engaging with the said lugs. A valve or deflector is hinged inside the shell over the
orifice of the said tube or perforation, the edges of such valve or deflector being
arranged to overhang or project round such orifice. A set screw preferably passing
through the cap closing the inlet nozzle of the lubricator bears upon the deflector, or
valve, and limits the extent to which it is opened when the lubricator is rotated or
agitated by the motion of the bearing. The inner form of the shell is such, that
when the lubricator is thus rotated or agitated its contents impinge against the
overhanging edges of the valve or deflector, thereby enabling a more or less minute
quantity of the lubricant to pass into the orifice of the tube or perforation, com-
municating with the bearing, according to the extent such deflector or valve is opened,
or the motion thereof limited by the said set-screw.
The shell or case of the improved lubricator is formed of brass, glass or other
suitable substance separate or in combination.

I DAVID NOWELL, of 20, Charles Street, Bradford, in the County, of York,
Consulting 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 :-
This invention relates to novel and useful improvements in lubricators for rotary,
reciprocatory and analogous bearings, such as loose pulleys, connecting rods, or other
bearings subject to rotation, oscillation, or reciprocation; and its object is economy
and convenience in the use of lubricants, effected by employing a lubricator of
improved construction adapted to uniformly feed or distribute the lubricant to such
bearings without waste, the quantity distributed being capable of adjustment.
The said improvements consist in providing a lubricator with means whereby the
centrifugal action, or the reciprocating motion, of the bearing or piece of mechanism
to which such lubricator is attached is utalised to direct the lubricant to the ducts
leading to the journal or axle thereof.
Reference is to be had to the accompanying forming a part of this specification in
which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a perspective view of the lubricator. Figure 2 is a plan of the
same.
Figure 3 is a section of the lubricator through the line 1, 2 in the former figure
showing the application and method of attachment to the boss of a loose pulley also
in section. Figure 4 represents a similar section of a lubricator applied to the end of
a connecting rod.
Referring to Figures 1, 2, and 3, A represents a journal or shaft, and B represents
the boss of a loose pulley rotating thereon. The said boss is provided with a radial
hole adapted to receive the outer end of the tube D forming the oil discharging
duct or passage of the lubricator E leading to the surface of the journal A, so that the
oil from the lubricator is directed to the said journal. Packing F is introduced, of
wood, cork or other suitable material, at the junction of the tube D with the boss B
to form the joint; and the lubricator is secured by the wire G passing round the
boss B, the ends of such wire being bent over to engage with the lugs H on the
lubricator case.
The lubricator E consists of a casing or box provided with an inlet or supply
nozzle J, and the discharge duct D above referred to. The bottom K of the oasing is
bent upwardly in inverted V shape, so that the tube D joins the rise of the bottom at
the centre thereof.
Within the casing is a deflector L, which consists of a plate hinged or pivotted at
one end of the bottom or sides of the casing and located above or overhanging the top
of the tube D, so as to open and close the same. The deflector is adjusted by a
screw M represented in Figure 1, fitted in the cap of the supply nozzle J, and in

page_text: Figures 2, and 3 it screws through the top of the casing, such screw is fixed by a jam
or set nut N.
It will be seen that when the pulley rotates in the direction of the arrow the oil in
the chamber of the casing on the left side thereof is directed by a centrifugal action
action up the inclined portion of the bottom of the casing and impringes against the
free end of the deflector L thus lifting the same and opening the top of the tube D,
so that the oil is directed into the said tube, and passed through the hole C to the
journal to be lubricated. The screw M. enables the feed of the oil to be adjusted with
great nicety as it limits the extent to which the deflector is opened and thus regulates
the passage of the oil.
Figure 4 represents a somewhat similar lubricator applied to the end of a
connecting rod, in which case the reciprocatory motion causes the oil to impringe
against the deflector and so pass into the duct D. The end of the said duct is
preferably screwed for the purpose of attaching the lubricator.
It is obvious that these improved lubricators may be applied to various other
bearings or pieces of mechanism the motion of which is sufficient to cause the oil to
impringe against the deflector and thus pass into the duct leading to the journal.
Having now particularly described and ascertained the nature of this said invention
and in what manner the same is to be performed I declare what I claim is :-
1. A lubricator consisting of a casing having a deflector within the same whereby,
by centrifugal action or oscillating or reciprocatory motion, the oil therein is directed
by the deflector to the discharge duct or outlet of the casing and thus to the journal
or shaft to be lubricated, substantially as and for the purpose set forth.
and
2. A lubricator having a casing which is formed with a bottom bent upwardly,
provided with a discharge duct communicating with the said casing at the upper end
of said bottom, substantially as herein shown and described and for the purpose
set forth.
3. A lubricator having a casing provided with a discharge duct and a deflector
within the casing overhanging the said duct, substantially as and for the purpose
set forth.
4. A lubricator having a discharge duct, a movable deflector within the same, and
an adjusting screw for said deflector, substantially as and for the purpose set forth.
5. In a lubricator, a casing having a discharge duct, a deflector over the entrance
end of said duct, an adjusting screw for said deflector, and a jam nut for said screw
substantially as and for the purpose set forth.
