PROVISIONAL SPECIFICATION.
Improvements in the Arrangement and Construction of Lubricators.
WILLIAM HENRY THOMPSON and ROBERT THOMPSON Engineers 155, Fen-
church Street, London, E.C. do hereby declare the nature of this invention to be
as follows:-
Our invention relates to improvements in Patent No. 2044 A.D. 1892. The
object of improvement being to minimize the effect of the action of heat on the
grease or lubricant when steam pressure is utilized for counterbalancing the force
opposing the exit of such grease from the lubricator whilst lubricating against high
pressure, also for the better arrangement and operation of the mechanism of parts,
containing or operating and indicating the passage of the lubricant against pressure.
In carrying our invention into practice when the lubricator is employed for
lubricating steam engine cylinder and other machinery resisting the introduction of
the lubricant in order to more effectually utilize steam pressure for counter-
balancing the pressure or forces opposing the introduction, or feed of the lubricant
we arrange a cylinder with two pistons arranged one on each end, or connected to
a piston rod, stem, or other suitable connection, so as to be set apart and form a
suitable space between the part of the cylinder arranged to contain the lubricant,
and the part charged with steam, and for further intercepting and opposing the
conduct of heat to the lubricant, we fill or compress into the said space asbestos,
cork or other suitably formed non conducting inaterial or fluid: also that part or
surface of the piston or pistons presented to the action of the steam or lubricant
may be faced with a suitable thickness of asbestos or other non conducting material
aforesaid when the piston rod stem or part is connected to the two pistons, such
connections may be combined with or intercepted by asbestos or other non conducting
material or such rod stem or part may be wholly or partially composed of non con-
ducting material. The cylinder may be divided into two or more separate parts so
arranged as to more effectually oppose the transmission of heat or such parts may
be connected or united by connections intercepted or combined with non conducting
material.
A hole is formed through either or both of the pistons and the rod or stem to
which they are connected such hole being screwed or arranged with a nut so that
it may receive the piston screw operating or travassing the piston or pistons, by its
connection with and operation of the adjustable train of wheels, ratchet or rotorary
motion, screw handle regulating index wheel and other mechanism and arrangements
for retaining, regulating, indicating and forcing or feeding the lubricant described
in Patent No. 2041 A.D. 1892 and herein after called the "combination of
mechanism." To avoid the chance of the mechanism or parts of the lubricator
being damaged from over pressure, or a greater strain on the piston than such
mechanism is calculated or dimensioned to work against, we provide a relief valve
combined with or operating in connection with the cylinder, or that part of the
lubricator in which the lubricant is contained, and in order to protect the parts of
such valve, from becoming clogged with dirt, and otherwise injured or effected, in
its operation from exposure when the lubricator is located in grinding mills or
industries where much dirt and matter is deposited, on the machinery, we arrange
such valve so that its spring or other pressure counterbalancing mechanism, is
presented to the lubricant or located in or towards the interior of the lubricant
containing cylinder, or other part to which it may be connected, whilst the plug or
that part of the valve stopping the outlet or resting on the seating being exposed
is extended beyond the said seating (preferably in globular form) so as to protect
its edges or exposed parts.
We further extend the utility of the plug sealing the aperture through which the

page_text: lubricant is charged by arranging it with a suitable outlet, globular plug, spring or
pressure counterbalancing mechanism arranged as aforesaid, so as to combine the
sealing plug and relief valve which arrangement we prefer as it admits of ready
removal of the valve for adjustment and other purposes.
In order that the piston may be adjusted from the exterior of the lubricator
without disturbing the cylinder ends or other parts, when the piston rod is made
to traverse through and extend beyond the end of the cylinder, we provide the said
rod with a moveable or sliding sleeve which is free to move or slide along the
piston rod, whilst it is traversing with it through a gland in the end of the cylinder:
one part of the said piston is preferably in the form of a loose disc for acting on
and compressing the piston packing between it and the discs, connected to the inner
end of the rod, which compression is effected from the exterior by the setting up of
a nut worked on a screw, cut on the outer end of the rod, and acting on the sleeve
travassing it on the rod and so thrusting it on the loose disc as to draw the two
discs together, tightening the packing in the surface of the cylinder: when two
such pistons are employed, they may be so adjusted, by the parts between the
sleeve and disc fixed on the inner end of the piston being loose so that they may
be thrust together as aforesaid.
In another arrangement of our invention we form the rod or part connecting the
two pistons with a screw, provided with a nut, with which is combined a bevil
wheel gearing into another bevil wheel connected to and worked on a spindle,
which spindle is substituted for the piston screw and operated in the same manner
by the herein before mentioned "combination of mechanism which combination is
arranged in a box or aperture formed in or on the side or other suitable position on
the cylinder or body of the lubricator and so that it may be worked either in a
vertical or horizontal position, worm or other suitable gearing may be substituted
for the said bevil wheels or a rack may be substituted for the screw, and operated
by a pinion arranged on the aforesaid spindle.
The cylinder, or part of the cylinder containing the steam is arranged with a
pipe or steam outlet passages with which is connected a whistle or similar alarm so
arranged that when the steam piston, in following the grease piston, has, in course
of its travel reached a point at which the lubricator should have been charged, it
contacts with a lever or other part of the whistle so as to open the whistle valve
or cock setting it in action and so sounding an alarm for the lubricator to be
recharged the motion of the grease piston or other moving part may be similarly
utilized for setting the whistle in action the position of the piston or the quantity
of the lubricant discharged may also be indicated by arranging a suitably figured
index plate or rod between the two pistons to which it may be connected and be of
sufficient strength to work in a guide so as to be utilized for preventing any
tendency of the piston to turn in the cylinder; in order that the indications on the
said plate may be observed and protected a suitable aperture is formed in the
cylinder at that part travassed by the index plate, the said aperture being closed
by a suitable glass plate marked with an index pointer for the index-the index
pointer may be arranged to travel with the piston and the index be marked on the
glass closing the aperture, or a suitable slot or aperture may be made through the
cylinder, through which aperture the index pointer travelling with the piston may
indicate on an index plate, on the outside of the cylinder-the operation may be
reversed and the pointer made stationary, while the index is carried by the piston
so as to work and indicate outside the cylinder-when found desirable to indicate
on a smaller or more convenient space than the distance traversed by the pistons,
an index hand or pointer or index is arranged with a nut working on a screw which
screw is combined with a bevil wheel gearing into one of the aforesaid bevil wheels
employed for working the pistons the travel of the index pointer or index, is
regulated by the number of threads forming the screw-when a circular dial is
employed for indicating for the same purpose the index pointer or hand is arranged
on a spindle connected with a pinion gearing into a rack arranged between the said
pistons so as to travel with them, and so cause the spindle to revolve the pointer or

page_text: hand round the dial which dial may be let in an aperture formed in the cylinder or
so arranged on its outer surface the dial may be attached to the spindle and
indicate with a stationary pointer or hand. This last mentioned rack may travel in or
between guides so as to be utilized to obviate any tendency of the pistons to turn
in the cylinder.
When the pressure at which the lubricant is discharged has to be indicated we
form a suitable box or aperture on the cylinder to receive the mechanism and parts
of a pressure gauge, or by passing and working the last mentioned spindle
(carrying the index pointer or hand through a hollow spindle or tube carrying the
pressure gauge hand, the pressure and discharge of the lubricant may be indicated
on one dial, thus combining the two indications.
"
The lubricator is charged by suction through an aperture in the top or end of
the cylinder when the grease is sufficiently soft, but, the arrangement of the
combination of mechanism in a box or aperture on the side, or longitudinal
surface of the cylinder, admits of a moveable cover forming its top or end, so that
a grease of a greater density may be charged into the cylinder with a "spatula,"
the said cover being screwed down by a screw arranged with a suitable bar
extending across it.
The grease cylinder may be provided with another cylinder surrounding it
forming a water or fluid reservoir for cooling the lubricant, or retaining a water
supply when a pump is employed for forcing fluid behind the piston.
When a rutorary motion is not available in order to obtain a continuous discharge
from a ratchet motion, we employ two ratchet levers and pawls working on, and
operating the ratchet wheel, the said levers being operated in opposite directions
preferably by an arrangement of toggle levers and springs so that the pawls of
each lever may be alternately in action on the ratchet wheel.
When the piston screw, stem or rod is arranged to extend and work through the
top or end of the cylinder and it is desirable to avoid the employment of glands we
provide the said top or end with a suitably sealed passage or case of such dimensions
to admit the said rod or stem to its fullest extent.
The lubricant may be arranged to pass through transparent water charged tube
or tubes connected with the lubricator for observing its passage.

COMPLETE SPECIFICATION.
Improvements in the Arrangement and Construction of Lubricators.
WILLIAM HENRY THOMPSON and ROBERT THOMPSON Engineers 155 Fen-
church 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 relates to improvements in Patent No. 2044 A.D. 1892. The
object of improvement being to minimize the effect of the action of heat on the
grease or lubricant when steam pressure is utilized for counterbalancing the force
opposing the exit of such grease from the lubricator while lubricating against high
pressures also for the better arrangement and operation of the mechanism of parts
containing or operating and indicating the passage of the lubricant against
pressure.
In carrying our invention into practices when the lubricator is employed for
lubricating steam engine cylinders and other machinery resisting the introduction
of the lubricant in order to more effectually utilize the steam pressure for counter-
balancing the pressure or forces opposing the introduction or feed of the lubricant
we arrange a cylinder with two pistons arranged one on each end of or connected
to a piston rod, stem, or other suitable connection, so as to be set apart and form a

page_text: suitable space between the part of the cylinder arranged to contain the lubricant
and the part charged with steam, and for further intercepting and opposing the
conduct of heat to the lubricant we fill or compress into the said space, asbestos,
cork or other suitably formed non-conducting material or fluid, also that part or
surface of the piston or pistons presented to the action of the steam or lubricant
may be faced with a suitable thickness of asbestos or other nonconducting material
aforesaid when the piston rod stem or part is connected to the two pistons, such
connections may be combined with or intercepted by asbestos or other nonconducting
material or such rod stem or part may be wholly or partially composed of non-
conducting material. The cylinder may be divided into two or more separate parts
so arranged as to more effectually oppose the transmission of heat or such parts
may be connected or united by connections intercepted or combined with
nonconducting material. A hole is formed through either or both of the pistons
and the rod or stem to which they are connected such hole being screwed or
arranged with a nut so that it may receive the piston screw operating or traversing
the piston or pistons, by its connection with and operation of the adjustable train.
of wheels, ratchet or rotary motion, screw handle regulating index wheel and other
mechanism and arrangements for retaining, regulating, indicating and forcing or
feeding the lubricant described in Patent No. 2044 A.D. 1892 (and herein after
called the combination of mechanism). To avoid the chance of the mechanism or
parts of the lubricator being damaged from over pressure, or a greater strain on
the piston than such mechanism is calculated or dimensioned to work against, we
provide a relief valve combined with or operating in connection with the cylinder,
or that part of the lubricator in which the lubricant is contained, and in order to
protect the parts of such valve from becoming clogged with dirt and otherwise
injured or effected, in its operation from exposure when the lubricator is located in
grinding mills or industries where much dirt and matter is deposited on the
machinery, we arrange such valve so that its spring or other pressure counter-
balancing mechanism, is presented to the lubricant or located in or towards the
interior of the lubricant containing cylinder, or other part to which it may be
connected, whilst the plug or that part of the valve stopping the outlet or resting
on the seating being exposed is extended beyond the said seating (preferably in
globular form) so as to protect its edges or exposed parts.
.
We further extend the utility of the plug sealing the aperature through which
the lubricant is charged by arranging it with a suitable outlet, globular plug,
spring or pressure counterbalancing mechanism arranged as aforesaid, so as to
combine the sealing plug and relief valve which arrangement we prefer as it admits
of ready removal of the valve for adjustment and other purposes. In order that
the piston may be adjusted from the exterior of the lubricator without disturbing
the cylinder ends or other parts, when the piston rod is made to traverse through
and extend beyond the end of the cylinder, we provide the said rod with a moveable
or sliding sleeve which is free to move or slide along the piston rod, whilst it is
traversing with it through a gland in the end of the cylinder: one part of the said
piston is preferably in the form of a loose disc for acting on and compressing the
piston packing between it and the discs, connected to the inner end of the rod,
which compression is effected from the exterior by the setting up of a nut worked
on a screw, cut on the outer end of the rod, and acting on the sleeve traversing it
on the rod and so thrusting it on the loose disc as to draw the two discs together
tightening the packing in the surface of the cylinder. When two such pistons are
employed, they may be so adjusted, by the parts between the sleeve and disc fixed
on the inner end of the piston being loose so that they may be thrust together as
aforesaid.
In another arrangement of our invention we form the rod or part connecting the
two pistons with a screw provided with a nut, with which is combined a bevil wheel
gearing into another bevil wheel connected to and worked on a spindle which
spindle is substituted for the piston screw and operated in the same manner by the
herein before mentioned combination of mechanism which combination is arranged

page_text: in a box or aperture formed in or on the side or other suitable position on the cylinder
or body of the lubricator and so that it may be worked either in a vertical or
horizontal position worm or other suitable gearing may be substituted for. the said
bevil wheels or a rack may be substituted for the screw, and operated by a pinion
arranged on the aforesaid spindle.
The cylinder, or part of the cylinder containing the steam is arranged with a pipe
or steam outlet passages with which is connected a whistle or similar alarm so
arranged that when the steam piston, in following the grease piston, has, in course
of its travel reached a point at which the lubricator should have been charged, it
contacts with a lever or other part of the whistle so as to open the whistle valve or
cock setting it in action and so sounding an alarm for the lubricator to be recharged
the motion of the grease piston or other moving part may be similarly utilized for
setting the whistle in action the position of the piston or the quantity of the
lubricant discharged may also be indicated by arranging a suitably figured index
plate or rod between the two pistons to which it may be connected and be of
sufficient strength to work in a guide so as to be utilized for preventing any
tendency of the piston to turn in the cylinder in order that the indications on the
said plate may be observed and protected a suitable aperture is formed in the
cylinder at that part traversed by the index plate, the said aperture being closed
by a suitable glass plate marked with an index pointer for the index the index
pointer may be arranged to travel with the piston and the index be marked on the
glass closing the aperture, or a suitable slot or aperture may be made through the
cylinder, through which aperture the index pointer travelling with the piston may
indicate on an index plate, on the outside of the cylinder. The operation may be
reversed and the pointer made stationary while the index is carried by the piston
so as to work and indicate outside the cylinder-when found desirable to indicate
on a smaller & more convenient space than the distance traversed by the pistons,
index hand or pointer or index is arranged with a nut working on a screw which
screw is combined with a bevil wheel gearing into one of the aforesaid bevil wheels
employed for working the pistons the travel of the index pointer or index, is
regulated by the number of threads forming the screw when a circular dial is
employed for indicating for the same purpose the index pointer or hand is arranged
on a spindle connected with a pinion gearing into a rack arranged between the said
pistons so as to travel with them, and so cause the spindle to revolve the pointer or
hand round the dial which dial may be let in an aperture formed in the cylinder or
so arranged on its outer surface, the dial may be attached to the spindie and
indicate with a stationary pointer or hand, this last mentioned rack may travel in
or between guides so as to be utilized to obviate any tendency of the pistons to
turn in the cylinder. When the pressure at which the lubricant is discharged has to
be indicated we form a suitable box or aperture on the cylinder to receive the
mechanism and parts of a pressure gauge, or by passing and working the last mentione.l
spindle (carrying the index pointer or hand) through a hollow spindle or tube
carrying the pressure gauge hand, the pressure and discharge of the lubricant may
be indicated on one dial, thus combining the two indications.
The lubricator is charged by suction through an aperture in the top or end of the
cylinder when the grease is sufficiently soft, but, the arrangement of the combination
of mechanism in a box or aperture on the side, or longitudinal surface of the
cylinder, admits of a movable cover forming its top or end, so that a grease of a
greater density may be charged into the cylinder with a spatula," the said cover
being screwed down by a screw arranged with a suitable bar extending across it.
The grease cylinder may be provided with another cylinder surrounding it forming
a water or Huid reservoir for cooling the lubricant or retaining a water supply,
when a pump is employed for forcing fluid behind the piston, when a rotary motion
is not available in order to obtain a continuous discharge from a ratchet motion.
we employ two ratchet levers, and pawls working on, and operating the ratchet
wheel the said levers being operated in opposite directions preferably by an
arrangement of toggle levers and springs so that the pawls of each lever may

page_text: alternately in action on the ratchet wheel. When the piston screw, stem or rod is
arranged to extend and work through the top or end of the cylinder and it is
desirable to avoid the employment of glands we provide the said top or end with a
suitably sealed passage, or case of such dimensions to admit the said rod or stem to
its fullest extent.
The lubricant may be arranged to pass through transparent water charged tube
or tubes connected with the lubricator for observing its passage.
DESCRIPTION OF DRAWINGS.
Fig. 1. Sheet 1. A represents the cylinder or part in which the lubricant is
coutained, B the piston acting on such lubricant, C. the stem connecting B to the
piston D, which piston is acted on by the counterbalancing steam pressure in the
cylinder E. The operation is as follow assuming the cylinder A to be charged
with the lubricant through the aperture opened by the removal of the screw
plug a. or the cover b. and the charged cylinder is again scaled by replacing such
plug or cover, and the feed pipes c. c. c. c. are connected to the steam pipe or pipes
(of the engine or engines to be lubricated) where the lubricant passing from A.
into and through such feed pipe meets with a resistance according to the pressure of
the steam in the said engine steam pipe which resistance is counterbalanced by the
connection of the steam pipe d. also with the said engine steam pipe from which
the steam pressure passes through d. into the cylinder E. and acts on the piston D.
which being of the same area as B. equalizing the pressure and balances the
pistons such balance being disturbed by the operation of the combination of
mechanism F. F. F. F. which causes the rotation of the bevel wheel G gearing
into and revolving the wheel H. in the bearing I. to which it is held by the
collar J. the bore of the wheel H. is cut with a thread so as to form a nut fitting
on the screw cut in the required direction on the stem C. the rotation of the
wheels G and H. by the operation of the combination of mechanism (described in
aforesaid Specification No. 2044) causes the screw to be worked and advance or
traverse the pistons so that the piston B. advances on the lubricant and forces it
from the cylinder through the aforesaid feed pipes into the steam lubricating as
it passes into the engine until the lubricant contained in the cylinder is discharged
when the cylinder is again recharged by the removal of the plug a. or cover b. and
working the piston back by operating the combination of mechanism as described
for the purpose in the aforesaid Specification, a cock not shown is arranged at the
bottom of the steam cylinder to be opened for blowing out steam or condensed
water when the piston is run back for recharging, when the steam pipe leading to
the cylinder is closed by another cock which cocks are reversed again when starting
the lubricator. In order to better insure recharging at the proper time the whistle
or alarm K is connected with a steam passage or pipe leading from the steam
cylinder so that the pressure of steam in the said cylinder may sound the whistle
when the piston D. is nearing the termination of its travel at which position it will
have passed the steam passage leaving it open for the admission of the steam to
sound the whistle until the piston cuts off the steam by being run back for
recharging. Compressed air, water, or other fluid under pressure may be employed
to act the counterbalancing power on the piston D. This arrangement of the
mechanism and parts admits of the end of the cylinder being formed as a removable
cover and the utilization of the space between the two pistons for location of the
operating mechanism and convenient arrangement of such mechanism when a
vertical lubricator is employed by necessity or preference also dispensing with
piston rod gland, L. M. and N. are discs of asbestos or other nonconducting
material and show the application of such material between the connection or
parts and on the piston surface for intercepting the conduct of heat from the
counterbalancing steam pressure in the steam cylinder.
