We, SAMUEL BOSWELL, of 38 Vero Street, Salford, Engineer, and THOMAS JAMES
CARTER, of 3, Mitchell Street, Monton Green, Salford, Engineer, do hereby declare
the nature of this invention to be as follows:
This invention consists of improvements in lubricators, our objects being to
construct a convenient lubricator that shall filter the oil before it passes on to the
journal or bearing, to provide simple means whereby the amount of oil passing
through the lubricator may be readily observed and controlled, and to so arrange
the parts of the complete apparatus that they can be readily connected and
disconnected, thus facilitating the thorough cleaning of the same as frequently as
may be required.
&
In the application of our invention, we construct the body of the lubricator
preferably from two glass cylinders placed end to end, the inner or adjacent ends
being closed by a metallic division plate having an elongated sleeve or
tube both on its upper and lower sides. In this manner we divide the body
of the lubricator into two parts, which respectively form an upper and a lower
reservoir:
The bottom of the lower reservoir is closed by a metallic plate, having an
elongated projecting sleeve or tube on its inner sido or end, and a shorter
cylindrical chamber or lantern on its outer end, with side apertures for inspection
of the oil feed as hereinafter described. The top of the upper reservoir is closed by
a plate which is fitted with regulating valves or appliances.
The top and bottom plates are clamped on to the ends of the glass cylinders,
and the whole of the parts secured together preferably by means of external
bolts and nuts,. tho bolts passing, through holes or apertures formed in projecting
lugs or flangos from the top and bottom plates. Within the lantern on the outer
side of the lower plate we place a short glass tube, and secure the same by a
screwed nipple or cap with which is also made the connection to the journal or
bearing to be lubricated.
The oil is first poured into the upper reservoir and allowed to flow freely into
the lower reservoir through the aleove or tube on the lower side of the central
division plate.
This sleeve or tube has also a projection into the upper reservoir,
for the purpose of preventing any dirt or sediment settling on the upper side of
the central division plate, from passing into the lower reservoir. The sleeve or
tube on the under side of the central plate extends nearly to the bottom of the lower
reservoir, whilst the sleeve or tube on the inner side of the lower plate extends
nearly to the bottom of the reservoir. The pure oil rises to the top of the lower
reservoir, and flows down the central sleeve or tube projecting from the lower plate
through the lantern and on to the bearing, but any dirt or grit contained in the
oil sinks to the bottom of either the upper or lower reservoir, and is thus prevented
from passing on to the bearing.
The quantity of oil passing through to the bearing is regulated by means of the
valves, which we preferably fit with thumb pieces for convenience in turning, the
valve stem of the lower reservoir passing through the central sleeve on the upper
side of the central division plate. The rate of feed can be readily observed through
the side apertures, and the inner glass tube of the lantern,

page_text: We sometimes provide pointers, or other indionting contrivances on the ends of
the screwed valve stems, and also fit them with locking devices when required.
The lubricator can also be used in connection with an oil pump to give a continuous
feed from waste oil below journal to the bearing, or in connection with any
oirculating medium.
The whole of the parts of the lubricator can be readily detached for cleansing
purposes by releasing the nuts at the ends of the external connecting bolts
hereinbefore described.
We do not limit ourselves to any one particular form or type of our improved
filtering lubricator, but make such modifications in the details and arrangements of
the same as may be necessary to suit varying requirements, without departing from
the essential features of our invention.

Improvements in Lubricators.
We, SAMUEL BOSWELL, of 38, Vere Street, Salford, Engineer, and THOMAS JAMES
CARTER, of 3, Mitchell Street, Monton Green, Salford, 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 consists of improvements in lubricators, our objects being to
construct a convenient lubricator that shall filter the oil before it passes on to
the journal or bearing, to provide simple means. whereby the amount of oil
passing through the lubricator may be readily observed and controlled, and to so
arrange the parts of the complete apparatus that they can be readily connected and
disconnected, thus facilitating the thorough cleaning of the same as frequently.ag
may
be required.
In the accompanying sheet of explanatory drawings to be hereinafter referred to.-
Figure 1 is a sectional elevation, Figure 2 a plan, and Figure 3 a front
elevation of our improved lubricator. The same reference letters in the différent
views indicate the same parts.
**
In the application of our invention we construct the body of the lubricator
preferably from two glass cylinders A A' placed end to end, the inner or adjacent
end being closed by a metallic division plate B having a sleeve, tronk, or tube,
such as B on its upper side, and B2 on its lower, sido. In this manner we divide
the body of the lubricator into two parts, which respectively. form an upper and
lower reservoir.
The bottom of the lower reservoir is closed by a metallic plate such as C,
having an elongated projecting sleeve or tube C¹ on its inner side or end, and a
shorter cylindrical chamber or lantern C on its outer end, with side apertures for
inspection of the oil feed as hereinafter described. The top of the upper reservoir.
is closed by a plate D which is fitted with regulating valves E and F, and a charging
plug G.
The top and bottom plates are clamped on to the ends of the glass cylinders,
and the whole of the parts secured together preferably by means of external bolts
und nuts H, the bolts passing through holes or apertures formed in projecting lugs.
or flanges from the top and bottom plates. Within the lantern on the outer

page_text: side of the lower plate, we place a short glass tube, and secure the same by a screwed
nipple or cap J, with which is also made the connection to the journal or bearing
to be lubricated.
The oil is first poured into the upper reservoir through the aperture at G, and
allowed to flow freely into the lower reservoir through the sleeve or tube B' on the
lower side of the central division plate. This sleeve or tube bas also a projection into
the upper reservoir, for the purpose of preventing any dirt or sediment settling
on the upper side of the contral division plate, from passing into the lower_reservoir.
The portion of tho sloeve or tube 'B' on the under side of the central plate B extends
nearly to the bottom of the lower reservoir, whilst the sleeve or tube O' on the inner
side of the lower plate C extends nearly to the top of the lower reservoir. The
pure oil rises to the top of the lower reservoir, and flows down the central sleeve or
tube C, passes the seating of the valve E and through the lantern and thus on
to the bearing to be lubricated by way of the connection at J; but any dirt or grit
contained in the oil sinks to the bottom or either the upper or lower reservoir, and
is thus prevented from passing on to the bearing.
The quantity of oil passing through to the bearing is regulated by means of the
valves E and F which we preferably fit with thumb pieces for convenience in turning,
the valve stom of the lower reservoir passing through the central sleeve B' on the
upper side of the central division plate. The rate of feed can be readily observed
through the side apertures, and the inner glass tube of the lantern C³.
We sometimes provide pointers, or other indicating contrivances on the ends of
the screwed valves stems for convenience in adjusting the rate of oil feed and also
fit them with nuts such as E' and F¹ or other locking devices. We sometimes
arrange an improved lubricator for use in connection with an oil pump to give a
continuous feed from waste oil below the journal to the bearing, or in connection
with any circulating medium.
The whole of the parts of the lubricator can be readily detached for cleaning
purposes by releasing the nuts at the ends of the external connecting bolts H
heroinbefore described.
To more effectually filter the oil and arrest any solid substance contained in the
same, we sometimes employ a pad of suitable material in either or both
compartments or reservoirs, and we also sometimes construct the lubricator with three
or more reservoirs or compartments, having communicating trunks, and connected
together by bolts and nuts as herein before described or in any other convenient
manner.
We do not limit ourselves to any one particular form or type of our improved
filtering lubricator, but make such modifications in the details and arrangements of
the same as may be necessary to snit varying requirements, without departing from
the essential features of our invention.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improved method of filtering the oil passing to a journal or bearing by
means of a lubricator having separate compartments or reservoirs provided with
communicating trunks arranged substantially as described.
2. The construction of a filtering reservoir having separate compartments or
reservoirs formed by glass cylinders closed at the ends by metallic plates provided
with connecting sleeves or tubes, the whole being secured together by bolts and
nuts substantially as hereinbefore described and as illustrated in the accompanying
drawings.
3. In lubricators, tho combination and arrangement of glass cylinders with metallic
plates forming separate compartments or reservoirs, the upper plate being fitted
with regulating valves, and the lower plate with a lantern and a connecting nipple,
cominunicating sleeves or tubes being provided upon each side of the intermediate
plate or plates and upon the upper or inner side of the lower plate, substantially as

page_text: and for the purposes hereinbefore described and as illustrated in the accompanying
drawings.
4. An improved lubricator constructed and arranged substantially as and for the
purposes described:
