Improvements in Apparatus for Applying Lubricators and
Conducting Lubricants to Bearing Surfaces.
WILLIAM HENRY THOMPSON ROBERT THOMPSON Engineers 155 Fenchurch
Street London, do hereby declare the nature of this invention to be as follows :-
Our invention has for its object improved methods of applying lubricators or con-
ducting lubricators to the reciprocating rotating and other moving bearing or
bearings surfaces of steam engines and other motors or machinery.
In carrying our invention into practice we employ a tube reciprocating in an
oscillating cylinder or chamber which may be sealed at both ends by suitable
glands the part of the tube working within the cylinder is provided with an
aperture or apertures through which the lubricant passes on its way to the bearing
which aperture or apertures may be of the same length as the whole or any part of
the stroke or traverse of the tube. When the tube is working in a smoothly
bored cylinder or a sealed chamber charged with the lubricant which passes from
the lubricator into the said cylinder through an aperture formed in the bearing on
which the cylinder or chamber oscillates one end of the tube is stopped and the other
end is connected to the slide block or moving bearing to be lubricated which bearing
it follows in its reciprocating motion. The operation is as follows the lubricator is
connected with the bearing or bearing surface on which the aforesaid cylinder or
chamber oscillates and delivers the lubricant through the hereinbefore mentioned
apertures into the tube by which it is conducted to the bearing surfaces with which -
the tube is connected, the tube being provided with suitable aperture or apertures
leading into or corresponding with the oil ways, pipes or chamber leading to slide
block connecting rod bearing or other moving bearings to be lubricated from the
said tube.
In another part of our invention for conducting the lubricant from a stationary
lubricator to the bearing surfaces of loose pulleys or other revolving bearings we
turn a part of the outer surface of the boss of the pulley true with the centre of
its rotation and form around such surface a groove of semicircular or other suitable
section and we arranged and fit the surface so prepared with a circular ring having
a groove in its interior surface corresponding with that formed on the aforesaid
boss on the pulley the two parts when so arranged form a channel (hereinafter
called the circular channel) for retaining or conducting the lubricant to the bearing
surface. The ring is provided with an inlet passage or passages leading into the
aforesaid circular channel which is also provided with outlet passages leading
through to the bearing surface. The operation is as follows the lubricator being
connected to the inlet passage of the ring by a pipe or other suitable connection by
which the ring is held stationary while the aforesaid boss revolves inside it the
lubricant delivered from the lubricator through the aforesaid pipe or other con-
nection passes into the inlet thereby charging the circular channel from which it
passes into the bearing surface of the pulley while it is revolving. The aforesaid
arrangement may be similarly combined with or adapted to other forms of revolving
bearings a ring or plug may be substituted for the boss and connected to a
revolving bearing so that while they are revolving inside the stationary ring con-
nected to the lubricator they are conducting the lubricant to the bearing surface
with which they are combined. In some instances we reverse the order of working
and revolve the outer ring (hereinafter called the stationary ring) delivering the
lubricant from it, instead of to it for example we adapt this arrangement for con-
ducting the lubricant to crank pins of engines and other similar bearings by

page_text: grooving and preparing the projected surface or end of the brasses of the bearing
nearest to the crank for receiving the outer ring and so forming a circular channel
(as aforesaid) with the inlet passage formed in the groove in the brasses or
stationary parts, the lubricant is conducted away from the revolving ring by means
of a conduit or tube connecting the outlet passage of the ring with the inlet
passage or oil way of the crank or connecting rod bearing so that while the said
ring is revolving with the crank it is conducting the lubricant to the bearing
surfaces a ring or plug as hereinbefore mentioned may be arranged with the
revolving ring such ring or plug being stationary and connected with the lubricator
so as to receive delivery of the lubricant, the surfaces of the parts may be of such
form as may be found best to retain the lubricant in the channel and acted upon by
pressure of a suitable nut and screw or spring intercepted by leather or other
suitable packing that may be essential for preventing leakage from the moving or
contact surfaces of the parts. The aforesaid arrangement and combination of parts
representing our invention may be modified as necessitated by the design or location
of the bearing surfaces for which it may be required.

Improvements in Apparatus for Applying Lubricators and
Conducting Lubricants to Bearing Surfaces.
WILLIAM HENRY THOMPSON and ROBERT THOMPSON Engineers 155
Fenchurch Street London E.C. 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 :-
Our invention has for its object improved methods of applying lubricators or
conducting lubricants to the reciprocating rotating and other moving bearing
or bearing surfaces of steam engines and other motors or machinery.
In carrying our invention into practice we employ a tube reciprocating in an
oscillating cylinder or chamber which may be scaled at both ends by suitable
glands the part of the tube working within the cylinder is provided with an aperture
or apertures through which the lubricant passes on its way to the bearing which
aperture or apertures may be of the same length as the whole or any part of the
stroke or traverse of the tube when the tube is working in a smoothly bored
cylinder or a sealed chamber charged with the lubricant which passes from the
lubricator into the said cylinder through an aperture or passage formed in the
bearing on which the cylinder or chamber oscillates, one end of the tube is stopped
and the other end is connected to the block or moving bearing to be lubricated
which bearing it follows in its reciprocating motion. The operation is as follows
the lubricator is connected with the bearing or bearing surface on which the
aforesaid cylinder or chamber oscillates and delivers the lubricant through the
bereinbefore mentioned apertures into the tube by which it is conducted to
the bearing surfaces with which the tube is connected, the tube being provided with
suitable aperture or apertures leading into or corresponding with the oil ways,
pipes, or chamber leading to slide block, connecting rod other bearings or other
moving bearing to be lubricated from the said tube.
The tube or part reciprocating in a smooth bored cylinder may be provided with
discs or rings so arranged on it as to form a piston at a suitable distance from each
side or end of the aforesaid aperture formed in this part of the said tube for the
inlet of the lubricant the pistons forming a bearing for the tube at the same time
sealing the grease and preventing its escaping from the cylinder except through
aperture.

page_text: The operation or arrangement of the cylinder or chamber and tube may vary
according to the varying conditions of working or the design or location of the
bearing to which they may be connected to or working in conjunction with.
In another part of our invention for conducting the lubricant from a stationary
lubricator to the bearing surfaces of loose pulleys or other revolving bearings we
turn a part of the outer surface of the boss of the pulley true with the centre of its
rotation and form around such surface a groove of semicircular or other suitable
section and we arrange and fit the surface so prepared with a circular ring having
a groove in its interior surface to correspond with that formed on the aforesaid boss
on the pulley the two parts when so arranged form a channel (hereinafter called
the circular channel) for retaining or conducting the lubricant to the bearing
surface.
The ring is provided with an inlet passage or passages leading into the aforesaid
circular channel which is also provided with outlet passages leading through to the
bearing surface. The operation is as follows the lubricator being connected to
the inlet passage of the ring by a pipe or other suitable connection by which the
ring is held stationary while the aforesaid boss revolves inside it, the lubricant
delivered from the lubricator through the aforesaid pipe or other connection passes.
into the inlet thereby charging the circular channel from which it passes into the
bearing surface of the pulley while it is revolving. The aforesaid arrangement
may be similarly combined with or adapted to other forms of revolving bearings a
ring or plug may be substituted for the boss and connected to a revolving bearing
so that while they are revolving inside the stationary ring connected to the
lubricator they are conducting the lubricant to the bearing surface with which they
are combined. In some instances we reverse the order of working and revolve the
outer ring hereinafter called the stationary ring delivering the lubricant from it
instead of to it for example, we adopt this arrangement for conducting the lubricant
to crank pins of engines and other similar bearings by grooving and preparing the
projected surfaces or end of the brasses of the bearing nearest to the crank for
receiving the outer ring and so forming a circular channel (as aforesaid) with the
inlet passage formed in the groove in the brasses or stationary parts, the lubricant
is conducted away from the revolving ring by means of a conduit or tube con-
necting the outlet passage of the ring with the inlet passage or oil way of the crank
or connecting rod bearing so that while the said ring is revolving with the crank it
is conducting the lubricant to .the bearing surfaces a ring or plug as hereinbefore
mentioned may be arranged with the revolving ring such ring or plug being
stationary and connected with the lubricator so as to receive delivery of the
lubricant the surfaces of the parts may be of such form as may be found best to
retain the lubricant in the channel and acted upon by pressure of a suitable nut and
screw or spring intercepted by leather or other suitable packing that may be
essential for preventing leakage from the moving or contact surfaces of the parts.
The aforesaid arrangement and combination of parts representing our invention
may be modified as necessitated by the design or location of the bearing surfaces
for which it may be required also any number of the aforesaid circular channels
may be combined with one bearing or bearing surface if found desirable.
DESCRIPTION OF DRAWINGS.
Sheet 1.-Fig. 1. shews a sectional elevation of the oscillating chamber with
tubes and connections.
Fig. 2. shews an enlarged sectional view of the joint for connecting the tube to
the moving bearing.
Fig. 3. shews a plan partly in section A. the feed pipe leading from the lubricator
and entering the passage formed in the bearing B. which is provided with the
gland (a) for sealing round the pipe and forming a properly sealed moving joint
the direction of the passage being shown by the arrows in Fig. 3. which arrows

page_text: also shew the direction followed by the lubricant when being fed to or passing
through the aperture C. formed in the tube D. reciprocating in the chamber or
cylinder E. from which the tube receives the lubricant through the aperture at
any part of its reciprocation or stroke which lubricant it conducts to the moving
bearing F. by means of its connection with such bearings by the joint G. to which
it is connected by the union nipple (b) the lubricant leaving the tube D. passes
through the nipple into and from the passages (cc) in joint and into the lubricant
passages (d) of the moving bearing from which (d) feeds any passages leading to
the bearing surfaces. B B. are the bearings or trunnions formed on the chamber;
by which the chamber is carried and arranged so as to oscillate in or on the
bracket bearing (e e) formed with the bracket H by which the cylinder is connected
and held in working position to any suitable part of the machinery or its framing,
(g) is a clamp for holding the pipe in proper relation to the gland (a) and (ƒ) is a
cap sealing the end of the tube D.
Sheet 2, Fig. 4. shows as an example application of the apparatus (shown and
described on Sheet 1.) to the moving bearings of a steam engine in which the
lubricant passing from the joint G. continue its course through the lubricant
passages of the top end bearings of the connecting rod the quantity of feed being
sufficiently in excess of that required for lubricating such bearings it passes on to
the bottom end or crank pin to which it is conducted by the pipe (h) while another
pipe (i) is extended from the lubricator I. to a second apparatus connected with
the eccentric to the bearing surface of which the lubricant is conducted and fed
through the passage (j) as herein before described.
The automatic lubricator I. is operated by the oscillation of the cylinder E. by
means of a cord and spring as shown so as to keep a constant feed of lubricant to
the bearing surfaces.
Sheet 3. Fig. 5. shows an end elevation of a standard with bearing shaft and
loose pulley and arranged with an automatic lubricator driven by rotary motion
from a grooved pulley fitted to the end of the shaft driving a cord working on and
imparting rotary motion to a similar pulley connected with the movements of the
lubricator.
Fig. 6. shows a front elevation partly in section shewing the arrangements for
conducting the lubricant to the bearing surfaces of the loose pulley A. from the
stationary lubricator I., the boss of the loose pulley is turned to provide a surface
for the ring B, such surface being formed with a semicircular groove corresponding
with a groove of the same section cut in the interior surface of the ring B. which
is arranged on the boss so that these two grooves form a circular lubricant
conducting chamber, the lubricating channels or conducting passages extending
from the bearing surface of the pulley and opening into the groove D. which
groove revolves with the pulley while the groove C. remains stationary with the
ring B. which is provided with an aperture tor the inlet of the grease to which
inlet the lubricator is connected by the feed pipe E.
Fig. 7 is an enlarged view of the arrangement shewn in Fig. 6.
The operation is as follows, the lubricator being worked from the shaft by a
cord as herein before mentioned forces the grease through the inlet into the
circular grease channel or chamber C and D, froin which it is forced through the
channel (a) which are thus kept charged with the quantity of lubricant required for
lubricating the bearing surface of the pulley while it revolves.
The stationary ring B. is set up in working position against the shoulder (b) by
the nut, c, the leather washers (d d) being intercepted to prevent escape of the
lubricant.
It will be obvious that the operation in the aforesaid arrangement can be
reversed where it may be found convenient for other forms of bearing by providing D.
with an inlet channel or feed pipe from the lubricator and making stationary while
the ring (b) revolves on it and is provided with a conducting pipe or passage
connected with such a bearing as it may be adapted to and revolved with
