PROVISIONAL SPECIFICATION.
Improvements in the Arrangement, Construction, Actuation, and
Application 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 on Patent No. 11,996 dated 21st Sept.
1886 and granted to William Henry Thompson one of the parties hereto. The
object of such improvements being arrangements for the more convenient or
effective adjustment and indication of the position of the movements, train of
wheels or mechanism employed for controlling or regulating the passage of the
lubricant and for indicating the quantity discharged from the lubricator or fed
to the bearing surfaces, also for signalling the position of the piston and working
it independently of the aforesaid movements in order to facilitate the flushing of
the bearing surfaces and for packing the piston and other parts when subjected
to high pressures further for operating the lubricator and conducting the lubricant
to certain bearings or bearing surfaces.
In carrying our invention into practice instead of adjusting setting or locking
the movements or train of wheels for regulating the passage of the lubricant by
means of a lever and index segment or plate as shown and described in the
Specification of the herein before mentioned Patent No. 11,996.---1886 we effect
the said adjustment and setting by means of an index wheel arranged outside the
lubricator and having a spindle which extends through the end or end plate or
cover of the lubricator into the interior so as to be fitted with a spur wheel or
pinion so arranged as to gear into a number of teeth cut on the periphery of the
wheel plate or frame carrying the train of wheels so that by turning the index
wheel any required wheel of the said train may be moved round into gear with
the ratchet wheel pinions which actuate them. The proper adjustinent of the
movements is effected by the index wheel having a number of interstices on its
periphery each arranged and numbered or marked so as to correspond with or
represent one of the wheels in the movable train and any one of such wheels
that may be selected for the adjustment or regulation of the passage of the
lubricant is set or locked in working position, by a spring bolt or catch falling
or fitting into the corresponding interstice on the index wheel.
Instead of the teeth being cut on the periphery of the wheel plate they may be
arranged on any other part of the plate or frame that may be found convenient.
A straight index may be substituted for the index wheel by lengthening or
extending the spindle of the said wheel a sufficient distance beyond its bearing to
admit of such extension being formed with a screw and arranged with a nut
carrying a spring catch or bolt acting as an index hand which when the spindle is
turned traverses an index plate formed with a number of interstices numbered and
marked so as to correspond with or represent the various wheels in the movable
train and so substituting the index wheel by forming an index by which the wheels
of the said train may be adjusted or brought into working position and set or
locked by the said spring or catch falling or fitting into such of the interstices as
may be selected for regulating the passage of the lubricant in this arrangement a
plain wheel takes the place of the index wheel for turning the spindle and spur
wheel gearing into and working the wheel plate or frame.
The arrangement of the index, and the form of the index hand may vary
according to the requirements.
The aforesaid movable train of wheels may be moved round and adjusted into

page_text: working position by the wheel plate or frame being directly connected to or formed
with an index wheel or segment working outside the lubricator and arranged with
suitable interstices and numbers or marks for indicating the position of any of the
wheels in the train by working in conjunction with a suitably arranged index hand,
spring, bolt, or catch, which falls or fits into any of the interstices selected for the
adjustment so as to set or lock the said index wheel and its connections in working
position the said wheel or segment may be provided with a suitable number of
teeth and worked by a wheel and pinion similar to the hereinbefore mentioned
arrangement for working the wheel plate.
Worm or other suitable gear may be employed to form the working connection
between the herein before mentioned index wheel or plain wheel and the wheel
plate or frame.
When it may be found convenient to continue the use of the hereinbefore
mentioned lever for adjusting or operating the wheel plate or frame in order to
avoid jerking and obtain a more uniform movement of the said lever when moving
any one of the train of wheels into working position we arrange the lever with a
wheel fitted with a pinion which gears into a suitable number of teeth arranged on
the index segment or plate, the spindle which connects the pinion to the aforesaid,
wheel by which it is operated is formed so as to admit of a spring bolt or catch
working in and through it and falling or fitting into the interstices in the index
segment or plate so as to set or lock the lever and its connections in working
position.
When the lubricator is employed for testing lubricants it is essential to indicate
the weight or quantity of lubricant displaced by the advance of the piston which is
arranged with a hollow rod working through a gland in the end of the cylinder of
the lubricator the said rod is formed hollow for the purpose of providing a space
for the screw by which the piston is actuated as described and shown in the
aforesaid Patent No. 11,996-1886-The said piston rod extending through the
end of the cylinder is provided with a suitable number of index hands which move
with it and traverse a suitable number of index plates arranged to extend beyond
the end of the cylinder.
The number of index or indicating plates employed will vary according to the
indications required one may be marked to indicate the number of ounces and units,
another the cubic inches and units displaced by the advance of the piston, another
the number of revolutions or movements made by the engine or machinery
operating the lubricator. Two or more of these indications may be combined
on one plate, the formation of the index hand may be varied to admit of the
indicating plates being arranged on other parts of the lubricator.
We obtain an indicator of less dimensions which in some instances may be more
convenient by arranging the piston screw at its exposed end with a minor screw
having the same number of threads as the piston screw but of a finer pitch and
provided with a nut carrying a suitable number of index hands and traversing them
over the required number of index plates arranged in proper relation to the said
screw and nut, the said index plates may be marked as herein before mentioned.
In order that the piston may be quickly advanced, independently of the
movements or train of wheels so that in the event of any of the bearing surfaces
with which the lubricator is connected becoming heated such surfaces may be
flushed or supplied quickly with a larger quantity of lubricant than the slow motion
of the movements would permit. We arrange the piston screw with a handle which
forms the connection between the said screw and the movements or train of wheels,
in such a manner that the screw may be worked by the handle and advance or
traverse the piston without disconnecting or effecting the movements or wheel train.
In this arrangement the boss of the main wheel of the movements or train of
wheels extends through and projects beyond the end of the lubricator such
extension being formed as or arranged with a ratchet wheel, the neck or shank
of the piston screw passes through and takes its bearing in the said boss beyond
which it extends a sufficient length to admit of its being fitted with a handle by
1

page_text: which the screw is turned which handle is formed so as to cover or partly cover
the ratchet wheel and carry a pawl engaging in its teeth and so forming such a
connection or contact with the handle as to force it and the screw round together
when the movements of the lubricator are in action at the same time admitting of
the handle and screw being turned independently by hand in the direction for
advancing the piston, the pawl moving with the handle and passing over the teeth of
the ratchet wheel which again works the screw by contact with the pawl and handle
when it is releived from the hand pressure. The pawl is arranged with a suitable
spring or catch so that it may be disengaged from and retained clear of the ratchet
wheel so that the handle and screw may be turned by hand in the direction for
returning the piston when the lubricator requires recharging which is effected by
the suction of the returning piston drawing the lubricant from a filling tube into
the lubricator or cylinder which tube may be sealed with a suitable plug when the
lubricator is charged or may be removed and the aperture to which it was con-
nected sealed, in order to prevent the said suction from drawing the grease or
lubricant out of the conducting pipes instead of the filling tube we arrange the
lubricator or conducting pipes with suitable check valves that the lubricant may
pass only in one direction.
A
The herein before mentioned handle for working the piston screw may also be
set in and out of gear with the main wheel by means of a suitable clutch or it may
be fitted on the screw so as to slide in and out of gear with teeth cut both on the
end of the boss of the main wheel and the handle that will interlock or pass each
other in one direction the handle being held into gear by a suitable spring or nut
and screw, and prevented from turning on the neck of the piston screw by a suitable
key, or by another arrangement the said handle may be set up to the main wheel
by traversing a screw on the neck of the said piston screw with threads inclining in
an opposite direction to those working or traversing the piston so that on turning
the handle in the direction for drawing the piston back for recharging the
lubricator, the handle releases itself from the main wheel and works back against
a shoulder or collar provided with a suitable catch by which it is retained so that
it may be turned in both directions and advance or return the piston and when
again released on turning it in the direction for advancing the piston it traverses
the screw and jams the main wheel between it and a shoulder on the piston screw
so connecting it with the movements or mechanism by which it is actuated.
hand wheel working under similar conditions may be substituted for the aforesaid
handle. When the lubricator is working under conditions that it may be desirable
to signal the arrival of the piston at any given point of its travel or to signal that
it has reached a position when the lubricator should be recharged we arrange an
electric bell in such relation to the piston rod that on its progress it comes into
contact with and presses the press button or contact or other device for completing
the circuit and setting the bell in action when the piston has reached the position
the said press button has been set or adjusted to signal. The press button or part
of its connections are arranged so as to admit of the necessary adjustment into
proper relation with the piston rod and either the said rod or the button may be
arranged with a suitable spring for the purpose of providing an elastic connection
that will give to the advancing piston rod and continue the pressure on the button
so keeping the bell in action until the piston is drawn back by the attendant. In
order that the piston may adjust itself so as to be sufficiently tight when forcing
the lubricant against high pressures we arrange a nut in the form of a boss at the
centre of a disc or plate which substitutes the ring hitherto employed for setting
up the packing from the back of the piston or that part nearest to the movements
the front or that part of the piston combined with the hollow piston rod is
arranged with a hole bored through it into the rod so as to receive and form a
bearing for the aforesaid nut and disc which is provided with a number of holes
arranged around its centre through which holes a series of screws are passed and
screwed into the front part of the piston so as to connect the two parts and hold the

page_text: packing in position, the piston screw actuates the piston by working in and through
the aforesaid nut and disc which is connected with the other part of the piston in
such a manner that the pressure against which it is forcing the lubricant acts on
and sets up the piston packing against the cylinder tightening the piston with a
force according to the pressure opposed to it. When pressure is admitted at the
back of the piston for equalizing the strain upon it and the movements by which
it is actuated, we provide the neck of the piston screw with a gland forming part
of a case or plate arranged for encasing or seperating the movements or train of
wheels from the interior of the cylinder and so retain the air or fluid under pressure
acting as the equalizing medium the said gland is provided with packing
surrounding the neck of the piston screw and a suitably formed ring or plug for
setting up the said packing by the equalizing fluid pressure or by the working
pressure of a collar or shoulder on the piston screw acting on its end surface or we
retain and prevent the air or fluid from escaping through or between the working
surfaces of the neck of the piston screw and its connections where they pass
through the end plate or end of the cylinder by providing this part with a suitable
gland so arranged as to surround and pack the boss of the handle employed for
actuating the piston screw by hand, the spindles of the index wheel and also that
of the ratchet wheel are provided with suitable glands for retaining the aforesaid
air or fluid under pressure. When the lubricator is actuated from a rotary motion
we substitute for the ratchet wheel and lever a cone pulley the grooves or steps of
which are graded or dimensioned and numbered so as to bear such relation to the
train of wheels as to be employed as a medium for subdividing each of the various
speeds they impart to the piston by their different changes so becoming part of the
system for regulating the displacement of the lubricant or movement of the piston
the ratchet wheel and lever may be arranged or combined with the said cone pulley
so as to adopt the lubricator either to a rotary or rectilinear motion, for high speed
it may be preferable to revolve the ratchet spindle by fitting it with a worm wheel
having a number of teeth in proper ratio to the other movements and worked by
a worm connected with a cone pulley as aforesaid. In another arrangement we
form the ratchet lever with a suitable slot or guide arranged to receive a pin set on
a crank plate so as to impart to the lever motion by working in the slot or guide
the crank plate is formed as a pulley for carrying a cord or band by which it is
operated and so arranged on the lubricator in such relation to the ratchet lever and
the movable plate or cover by which it is carried that the motion of the lever may
be regulated for the pawl to pass over a given number of teeth by moving round
the said plate or cover and setting it when the adjustment is effected or instead of
working the crank pin in a slot as aforesaid the ratchet lever may be made in two
parts the end extending from the pawl arranged with a boss provided with a hole
fitting the crank pin these two parts are connected near the pawl by a connection
that may be converted into a working joint in such a manner that the part one with
the boss or crank pin hole may be adjusted so as to form a connecting rod
connecting the crank pin by means of the said hole to the part carrying and working
the pawl in such a manner that the rotation of the crank plate and pin imparts the
necessary motion to the pawl for actuating the ratchet wheel, the pawl may be
regulated to work over the required number of teeth by altering the position of the
crank pin on the plate so as to shorten or lengthen the stroke as may be required.
The lubricator may under many conditions be advantagously actuated from a
revolving shaft by a cord attached to the ratchet lever at one end and to some fixed
point at the other for such an arrangement it is important to have some ready
device for lifting or imparting the necessary movement to the cord we effect this by
providing a cresent formed spring clip combined with an adjustable grooved
pulley or roller arranged so that it may be adjusted to extend beyond the clip
sufficient distance to impart the necessary action to the cord the said clip is attached
to the shaft from which the lubricator is actuated by forcing the two points of its
cresent over the centre line of the shaft which they grip sufficiently tight to carry

page_text: the grooved pulley round with the shaft so that it operates the cord when so
arranged that the pulley can properly contact with it at each end at each revolution
the eye, link, or part by which the cord is connected to the ratchet lever is
arranged or combined with a suitable spring or adjustable grip for facilitating the
adjustment of and setting of the cord. When arranged on a crank pin bearing of
a connecting rod the lubricator is actuated by a cam or projection arranged on the
crank pin or crank in such a manner that the ratchet lever can be set into contact
with it and so receive its motion from the rotation of the crank, or the ratchet
lever may be worked by means of an adjustable rod connecting it with a suitably
arranged fixed stud or pillar on the crosshead or slide block of the piston rod,
instead of being fixed on the crank pin bearing, the lubricator may be arranged on
the connecting rod near the crosshead or slide block bearings and connected to them
by pipes arranged in the form of a spring or coil so as to be elastic and give to the
motion of the connecting rod at the same time conducting the lubricant to the
bearings, a pipe may also be led from the lubricator to the crank pin bearing so
that all these moving bearings may be lubricated from the one lubricator, in this
arrangement of the lubricator the ratchet lever may also be worked by a rod
connecting it to fixed stud or pillar on the crosshead as aforesaid.
The lubricator may be arranged with the same effect on the crosshead and
connected to the connecting rod bearing by means of spring pipes in the manner
aforesaid and the ratchet lever actuated by a stud or pillar fixed on the connecting
rod. The aforesaid arrangement and application of the lubricator may be
employed for lubricating the moving bearings of engines and machinery that is
stopped at short intervals which admit of the adjustment and recharging of the
lubricator, but for marine and other engines that are constantly working for
comparatively long periods it is essential to have the lubricator fixed in an
accessible position and actuated from any convenient motion of the machinery,
under such conditions we arrange the lubricator with a suitable main preferably
run along the back of the engines if vertical and connected to the crosshead or
slide block or blocks of each engine by a pipe part of which is arranged preferably
around the said main pipe in the form of a coil or spiral so as to spring and give to
or follow the movement of the crosshead or moving bearing to which it connected
by a ball or other suitable joint, the coil or spring pipe is set or arranged so as to
act with spring force on the said ball joint or other connection and follow the
movement of the crosshead instead of being pulled after it. The arrangement of
pipes and oil or grease ways continued from the spring pipe and joint or connection
is such as to conduct the lubricant to and admit of its being forced into all the
herein before mentioned moving bearings, branch pipes may also be led from the
main pipe to the main or other bearings of the engines lubricating them also from
the same lubricator, the said pipes may be made in the form of a long spiral
extending from the lubricator or main pipes to the ball joint or other connection
on the crosshead or moving bearings. In another arrangement the main pipe is
intercepted or arranged with a cross joint or rocking piece to which the spring pipe
is connected and from which it extends in a straight line (except where it is
intercepted by and united with two coils forming the spring and arranged so as to
balance each other) to the joint or connection on the crosshead or movable bearing
and so admitting of its radiating from the joint at the main pipe while it is following
and springing to the motion of the crosshead to which it is conducting the
lubricant, the aforesaid joint or rocking piece at the main pipe is provided with
suitable glands for making a proper working joint. The spring pipe may be
strengthened or supported by the addition of guides or springs and the arrangement
and number of such pipes and mains may be varied according to the position of, or
the numbers of bearings to be lubricated and other working conditions. Any of
the herein before mentioned regulating wheels or indexes may be adapted or
combined with any modification of the movements employed for regulating the
travel of the piston or passage of the lubricant.
When the lubricator is employed for testing lubricant the electric bell
may
be

Improvements in the Arrangement, Construction, Actuation, and
Application of Lubricators.
WILLIAM HENRY THOMPSON and ROBERT THOMPSON Engineers 155 Fen-
church Street London 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 on Patent No. 11996 dated 21st Sept.
1886 and granted to William Henry Thompson one of the parties hereto the
object of such improvements being the arrangements for more convenient or
effective adjustment and indication of the position of the movements, train of
wheels or mechanism employed for controlling or regulating the passage of the
lubricant and for indicating the quantity discharged from the lubricator or fed to
the bearing surfaces, also for signalling the position of the piston and working it
independently of the aforesaid movements in order to facilitate the flushing of
the bearing surfaces and for packing the piston and other parts when subjected to
high pressures further for operating the lubricator and conducting the lubricant to
certain bearings or bearing surfaces.
In carrying our invention into practice instead of adjusting setting or locking
the movements or train of wheels for regulating the passage of the lubricant by
means of a lever and index segment or plate as shown and described in the
Specification of the herein before mentioned Patent No. 11,996, 1886, we effect
the said adjustment and setting by means of an index wheel arranged outside the
lubricator and having a spindle which extends through the end or end plate or
cover of the lubricator into the interior so as to be fitted with a spur wheel or
pinion so arranged as to gear into a number of teeth forming a segmental rack ou
the periphery of the wheel plate or frame (hereinafter called the wheel carriage)
carrying the train of wheels so that by turning the index wheel, any required
wheel of the said train may be moved round into gear with the ratchet wheel pinions
which actuate them. The proper adjustment of the movements is effected by the
index wheel having a number of interstices on its periphery each arranged and
numbered or marked so as to correspond with or represent one of the wheels in
the movable train and any one such wheels that may be selected for the adjustment
or regulation of the passage of the lubricant is set or locked in working position
by a spring bolt or catch falling or fitting into the corresponding interstice on the
index wheel.
Instead of the teeth being cut on the periphery of the wheel plate they
may be arranged on any other parts of the wheel carriage that may be found
convenient. A straight index may be substituted for the index wheel by lengthening
or extending the spindle of the said wheel a sufficient distance beyond its bearing
to admit of such extension being formed with a screw and arranged with a nut
carrying a spring catch or bolt acting as an index hand which when the spindle is
turned traverses an index plate formed with a number of interstices numbered and
marked so as to correspond with or represent the various wheels in the movable
train and so substituting the index wheel by forming an index by which the wheels
of the said train may be adjusted or brought into working position and set or
locked by the said spring or catch falling or fitting into such of the interstices as
may be selected for regulating the passage of the lubricant, in this arrangement a

page_text: plain wheel takes the place of the index wheel for turning the spindle and spur
wheel gearing into and working the wheel ccarriage.
The arrangement of the index, and the form of the index hand may vary
according to the requirements.
The aforesaid movable train of wheels may be moved round and adjusted into
working position by the wheel carriage being directly connected to or formed with
an index wheel or segment working outside the lubricator and arranged with
suitable interstices and numbers or marks for indicating the position of any of the
wheels in the train by working in conjunction with a suitably arranged index hand
spring bolt or catch which falls or fits into any of the interstices selected for the
adjustment so as to set or lock the said index wheel and its connections in working
position the said wheel or segment may be provided with a suitable number of
teeth and worked by a wheel and pinion similar to the herein before mentioned
arrangement for working the wheel plate.
Worm or other suitable gear may be employed to form the working connection
between the herein before mentioned index wheel or plain wheel and the wheel
carriage.
When it may be found convenient to continue the use of the hereinbefore
mentioned lever for adjusting or operating the wheel carriage in order to avoid
jerking and obtain a more uniform movement of the said lever when moving any
one of the train of wheels into working position we arrange the lever with a
wheel fitted with a pinion which gears into a suitable number of teeth forming a
segmental rack on the index segment or plate, the spindle which connects the pinion
to the aforesaid wheel by which it is operated is formed so as to admit of a spring,
bolt or catch working in and through it and falling or fitting into the interstices in
the index segment or plate so as to set or lock the lever and its connections in
working position.
When the lubricator is employed for testing lubricants it is essential to indicate
the weight or quantity of lubricant displaced by the advance of the piston which
is arranged with a hollow rod working through a gland in the end of the
cylinder of the lubricator the said rod is formed hollow for the purpose of
providing a space for the screw by which the piston is actuated as described and
shown in the aforesaid Patent No. 11,996,-1886. The said piston rod extending
through the end of the cylinder is provided with a suitable number of index hands
which move with it and traverse a suitable number of index plates arranged to
extend beyond the end of the cylinder. The number of index or indicating plates
employed will vary according to the indications required one may be marked to
indicate the number of ounces and units another the cubic inches and units displaced
by the advance of the piston, another the number of revolutions or movements
made by the engine or machinery operating the lubricator. Two or more of
these indications may be combined on one plate, the formation of the index hand
may be varied to admit of the indicating plates being arranged on other parts of
the lubricator.
We obtain an indicator of less demensions which in some instances may be more
convenient by arranging the piston screw at its exposed end with a minor screw
having the same number of threads as the piston screw but of a finer pitch and
provided with a nut carrying a suitable number of index hands and traversing
them over the required number of index plates arranged in proper relation to the
said screw and nut, the said index plate may be marked as hereinbefore mentioned.
In order that the piston may be quickly advanced independently of the
movement or train of wheels so that in the event of any of the bearing surfaces
with which the lubricator is connected becoming heated such surfaces may be
flushed or supplied quickly with a larger quantity of lubricant than the slow
motion of the movement would permit. We arrange the piston screw with a
handle which forms the connection between the said screw and the movement or
train of wheels, in such a manner that the screw may be worked by the handle and
advance or traverse the piston without disconnecting or effecting the movements or

page_text: wheel train. In this arrangement the boss of the main wheel of the movements
or train of wheels extends through and projects beyond the end of the lubricator,
such extension being formed as, or arranged with a ratchet wheel, the neck or
shank of the piston screw passes through and takes its bearing in the said boss
beyond which it extends a sufficient length to admit of its being fitted with a
handle by which the screw is turned which handle is formed so as to cover or
partly cover the ratchet wheel and carry a pawl engaging in its teeth and so
forming such a connection or contact with the handle as to force it and the screw
round together when the movements of the lubricator are in action at the same
time admitting of the handle and screw being turned independently by hand in the
direction for advancing the piston the pawl moving with the handle and passing
over the teeth of the ratchet wheel which again works the screw by contact with
the pawl and handle when it is relieved from the hand pressure. The pawl is
arranged with a suitable spring or catch so that it may be disengaged from and
retained clear of the ratchet wheel so that the handle and screw may be turned by
hand in the direction for returning the piston when the lubricator requires
recharging which is effected by the suction of the returning piston drawing the
lubricant from a filling tube into the lubricator or cylinder which tube may be
sealed with a suitable plug when the lubricator is charged or may be removed and
the aperture to which it was connected sealed, in order to prevent the said suction
from drawing the grease or lubricant out of the conducting pipes instead of
the filling tube we arrange the lubricator or conducting pipes with suitable
check valves that the lubricant may pass in only one direction.
The hereinbefore mentioned handle for working the piston screw may also be set
in and out of gear with the main wheel, by means of a suitable clutch or it may be
fitted on the screw so as to slide in and out of gear with teeth cut both on the end of
the boss of the main wheel and the handle that will interlock or pass each other in one
direction, the handle being held into gear by a suitable spring or nut and screw,
and prevented from turning on the neck of the piston screw by a suitable key or by
another arrangement, the said handle may be set up to the main wheel by traversing
a screw with threads inclining in an opposite direction to those working or
traversing the piston so that on turning the handle in the direction for drawing the
piston back for recharging the lubricator, the handle releases itself from the main
wheel and works back against a shoulder or collar provided with a suitable catch
by which it is retained so that it may be turned in both directions and advance or
return the piston and when again released on turning it in the direction for
advancing the piston it traverses the screw and jams the main wheel between it and
a shoulder on the piston screw so connecting it with the movements or mechanism
by which it is actuated, a hand wheel working under similar conditions may be
substituted for the aforesaid handle.
When the lubricator is working under conditions that it may be desirable to signal
the arrival of the piston at any given point of its travel or to signal that it has reached
a position when the lubricator should be recharge we arrange an electric bell in
such relation to the piston rod that in its progress it comes into contact with an
presses the press button or contact or other device for completing the circuit and
setting the bell in action, when the piston has reached the position the said press
button has been set or adjusted to signal. The press button or part of its
connection are arranged so as to admit of the necessary adjustment into proper
relation with the piston rod and either the said rod or the button may be arranged
with a suitable spring for the purpose of providing an elastic contact that will give
to the advancing piston rod and continue the pressure on the button so keeping the
bell in action until the piston drawn back by the attendant. In order that the
piston may adjust itself so as to be sufficiently tight when forcing the lubricant
against high pressure we arrange a nut in the form of a boss at the centre of a
disc or plate which substitutes the ring hitherto employed for setting up the packing
from the back of the piston or that part nearest to the movements the front of that
part of the piston combined with the hollow piston rod is arranged with a hole

page_text: bored through it into the rod so as to receive and form a bearing for the aforesaid
nut and disc, which is provided with a number of holes arranged around its centre
through which holes a series of screws are passed and screwed into the front part
of the piston so as to connect the two parts and hold the packing in position the
piston screw actuates the piston by working in and through the aforesaid nut and
disc which is connected with the other part of the piston in such a manner that the
pressure against which it is forcing the lubricant acts on and sets up the piston
packing against the cylinder, tightening the piston with a force according to the
pressure opposed to it. When pressure is admitted at the back of the piston for
equalizing the strain upon it and the movements by which it is actuated, we
provide the neck of the piston screw with a gland forming part of a case or plate
arranged for encasing or separating the movements or train of wheels from the
interior, of the cylinder and so retain the air or fluid under pressure acting
as the equalizing medium. The said gland is provided with packing surrounding
the neck of the piston screw and a suitably formed ring or plug for setting up
the said packing by the equalizing fluid pressure or by the working pressure
of a collar or shoulder on the piston screw acting on its end surface, or
we retain and prevent the air cr fluid from escaping through or between the
working surfaces of the neck of the piston screw and its connections where
they pass through the end plate or end of the cylinder by providing this
part with a gland so arranged as to surround and pack the boss of the handle
employed for actuating the piston screw by hand the spindles of the index wheel
and also that of the ratchet wheel are provided with suitable glands for retaining
the aforesaid air or fluid under pressure.
When the lubricator is actuated from a rotary motion we substitute for the
ratchet wheel and lever, a cone pulley the grooves or steps of which are graded,
dimensioned and numbered so as to bear such relation to the train of wheels as to
be employed as a medium for subdividing each of the various speeds they impart to
the piston by their different changes, so, becoming part of the system for regulating
the displacement of the lubricant or movement of the piston, the ratchet wheel and
lever may be arranged or combined with the said cone pulley so as to adapt the
lubricator either to a rotary or rectilinear motion for high speed it may be pre-
ferable to revolve the ratchet spindle by fitting it with a worm wheel having a
number of teeth in proper-ratio to the other movements and worked by a worm
connected with a cone pulley as aforesaid.
In another arrangement we form the ratchet lever with a suitable slot or guide
arranged to receive a pin set on a crank plate so as to impart to the lever motion
by working in the slot or guide, the crank plate is formed as a pulley for carrying
a cord or band by which it is operated and so arranged on the lubricator in such
relation to the ratchet lever and the movable plate or cover by which it is carried
that the motion of the lever may be regulated for the pawl to pass over a given
number of teeth by moving round the said plate or cover and setting it when the
adjustment is effected or instead of working the crank pin in a slot as aforesaid the
ratchet lever may be made in two parts the end extending from the pawl arranged
with a boss provided with a hole fitting the crank pin these two parts are connected
near the pawl by a connection that may be converted into a working joint in such
a manner that the one with the boss or crank pin hole may be adjusted so as to
form a connecting rod connecting the crank pin by means of the said hole to the
part carrying and working the pawl in such a manner that the rotation of the
crank plate pulley or crank plate and pin imparts the necessary motion to the pawl
for actuating the ratchet wheel, the pawl may be regulated to work over the
required number of teeth by altering the position of the crank pin on the plate so
as to shorten or lengthen the stroke as may be required.
In order to conduct the lubricant to the moving bearing of steam engines and
other machinery we arrange a coiled or spring pipe connected to and working
with joints provided with grease ways or passages that admit of the lubricant
passing into and from the said pipe one of such joints working on a fixed point
B

page_text: connected with the lubricator and the other joint being connected to the slide-
block or other moving bearing so as to admit of the coil or spring pipe giving to
or following the movements of such bearing at the same time conducting the
lubricant to the bearing surfaces of its connections, although we preferably employ
a pipe coiled in the form of a flat spiral, the pipe may be in the form of a long
spiral connecting to and extending from the joint at the fixed point to the joint on
the moving bearing or the form of coil may vary according to the requirements of
the moving bearing it has to be applied to.
When the lubricator is employed for testing lubricants, the electric signal bell
may be arranged to act in conjunction, with any of the indexes so as to signal the
displacement of any given quantity or weight of lubricant.
The hereinbefore mentioned segmental rack and spur wheel or pinion with
index wheel and spring bolt or catch or plain wheel, and indexes and spring bolt
or catch may be adapted to or combined with any modified form or arrangement
of the wheel carriage, wheels, movements or parts, working with or carried by it.

A, is the body of the lubricator B, B are the two parts forming the piston, C, is
the space occupied by the lubricant, D, is the hollow piston rod, containing the
piston screw E, for traversing the piston by working within the internal thread F
cut in the boss, formed in the back part of the piston B: G is a shoulder formed on the
piston screw for taking the thrust of the piston which is utilized for making a tight
joint, around the neck of the piston screw by acting on the ring or plug H and
thereby compressing the packing contained in the stuffing box, so as to prevent
the escape of the fluid under pressure acting on the back of the piston as a
counterbalance.
The neck of the piston screw passing through the stuffing box and extending
beyond the plate I is fitted with the main wheel J which gears with the first wheel
of the train of wheels, numbered, 1. 2. 3. 4. 5. (Figs. 5. 6. 7. 8. 9. 10) which regulate
the feed of the lubricant by regulating the travel of the piston, being so carried
on the plate K K' (which with the pillars a, a, a, form the combination of parts
hereinafter called wheel carriage) that each wheel of the train may be alternately
moved into gear with the ratchet motion pinions, d, d¹, each wheel being pro-
portioned so as to cause the piston to travel four times faster or slower than the
other according to the direction from which they are brought into gear with the
said pinions d, d¹, as indicated by the words "FAST" and "SLOW" marked on
the index wheel M which wheel revolves or operates the wheel carriage by its con-
nection with the wheel L, gearing into the segmental rack formed on the plate K.
The part of the boss of the main wheel extending through and beyond the operating
end plate, l, is formed in the manner of a ratchet wheel with teeth b, the neck of
piston screw passing through and taking its bearings in the boss of the main wheel
beyond which it extends a sufficient length to be fitted with the handle N (by a
screw and pin as shewn at e.) by which the screw is turned, which handle covers
the ratchet teeth and is combined with the pawl e engaging in the teeth b, so that
the main wheel J forces it and the piston screw round together when the movements
or mechanism are in action, at the same time admitting of the handle and screw
being turned independently in the direction for advancing the piston, the pawl
moving with the handle, and passing over the teeth 6 which again works the screw

page_text: by contact with the pawl when the handle is relieved from the hand pressure; the
pawl is arranged that it may be disengaged from the teeth and retained clear of
them by the spring, f, so that the handle N and piston screw E, may be turned by
hand in the direction for returning the piston B, B₁ when the lubricator requires
recharging which is effected by the suction of the returning piston drawing the
lubricant from a filling tube T into the cylinder or space C (as shewn by the dotted
lines Fig. 4.) which tube is again removed, the cylinder being charged, the plug U
replaced leaving the lubricator in action. The check or ball valves P. P. P. are
provided in order to prevent the aforesaid suction of the returning piston from
drawing the lubricant out of the delivery or conducting pipes leading from the
lubricator to the several bearings with which it may be connected, thus insuring
the passage of the lubricant in an outward direction only. The movement or train
of wheels 1. 2. 3. 4. 5. the main wheel J, the piston screw and piston are operated
by the pinions d, d, and the ratchet motion O, O'. The gland D' is provided for
the purpose of sealing the aperture through which the hollow piston D passes.
The
pressure employed for counterbalancing the piston is brought from any avail-
able source by means of a pipe, being connected to the aperture V. as, for example,
if the lubricator is employed for lubricating the cylinders of pumping engines such
pipe would be connected to the pump delivery pipe so as to charge the cylinder
at the back of the piston with water at about the same pressure as that opposing
the advance of the piston, which water is drawn off when returning the piston for
recharging the lubricator by providing a suitable cock or cocks for shutting off the
water under pressure and allowing that in the cylinder to flow away.
The adjustment or travel of the piston is regulated by the index wheel operating
the wheel carriage through the medium of the wheel L. and segmental rack so as
to bring every other wheel of the train alternately into gear with the pinions d. d¹
increasing or diminishing the speed or travel of the piston according to the
direction in which the wheel carriage is turned as indicated by the words "FAST"
and "SLOW" on the index wheel.
Each one of the wheels of the train are held into gear with the pinions d. d'
and represented by the figures or interstices on the said index wheel and the
object of having the two pinions d. d' is that the motion imparted to the main
wheel may be in one direction which is effected by gearing No. 1 wheel with the
pinion d, No. 2 with d¹, No. 3 with d, No. 4 with , No. 5 with d, these wheels as
aforesaid being proportioned at a ratio of 4 to 1 larger than their pinions, the
effect of each wheel to wheel adjustment is to cause the piston to travel four times
faster or slower, for example, in the several figures shewn in drawings, the
No. I wheel is in gear as indicated by the index wheel if the index wheel is turned
round so as to bring No. 2 interstice into such position that the spring catch M
engages into and locks it: No. 2 wheel will be set into gear with the pinion d' and
the travel of the piston will be 4 times slower engaging the spring catch into
No. 3, will have the effect of bringing No. 3 wheel into gear with pinion d,
causing the travel of the piston to be four times slower than when set at No. 2
and so on with the other numbers shewn on the index wheel of course turning
the index wheel in the opposite direction the speed of the piston is increased in the
same ratio.
The ratchet lever is operated by connecting it with any suitable motion of the
machinery near which the lubricator is located, the connection may be by a cord
attached to one of the holes marked, y, at one end and the aforesaid motion at the
other end the said holes are arrangened so that by attaching the cord or connection
at a hole nearer to the centre from which the lever radiates, so shortening the
leverage that the pawl may engage in two or three teeth for the purpose of dividing
the wheel to wheel adjustment indicated by the index wheel for instance if the paw!
is working on one tooth of the ratchet wheel and the index wheel shows that
No. 1. wheel of the train is in action and feeding the lubricant in excess of what is
necessary the attendant will set the index wheel at No. 2 which being as herein-
before mentioned 4 times slower may be feeding a less quantity than is required the

page_text: difference between the wheel to wheel adjustment may be proportionally increased
by engaging the pawl with two or three teeth of the ratchet wheel which arrange-
ment applies to each wheel to wheel adjustment made by the index wheel. It is
necessary under some conditions such as when the lubricator is employed for testing
lubricants to indicate the quantity of lubricant the piston has displaced the index
plate (S) is provided for this purpose, and marked off into spaces representing
measurement and weight for example ounces and cubic inches the number of which
displaced by the piston is shown by the index hands h. for the measurement, and i.
for the weight, which index hands move with the piston B. B' by being connected
with the hollow piston rod D. by the forked arm R. and the adjustment rod j. also
it may be necessary or desirable to know by what number of revolutions such
quantity and weight of lubricant is displaced and for such purpose the index
plate S is provided which is connected to the forked arm R. and operated in the
same manner as S. and marked for example into divisions of 3 of an inch which
(with a piston screw having 10 threads per inch) is the travel or displacement of
the piston per 100 revolutions when the index wheel is set at No. 1 and the pawl
working or engaging in one tooth of the ratchet wheel O, by the word revolution
is meant the movements of the motion by which the lubricator or ratchet motion
is operated for instance if it were operated by the valve gear of an engine each
movement of such gear would represent a revolution of the crank shaft.
Taking No. 1. on the index wheel as the standard giving 3 of an inch travel or
displacement of the piston per 100 revolutions or movements as each of the wheels
in the train are 4 to 1 as hereinbefore mentioned when an adjustment is made to
No. 2 of the index wheel the same indication viz. 3 would represent, 400 revolu-
tions, and so on each of the adjustments the number of revolutions would have to
be calculated according to the adjustment represented by the index wheel and the
number of teeth engaged by the pawl of the ratchet motion, of course in actual
operation these calculations would be tabulated in a simple form.
W. is the nut by which the end plate l. and its connections are secured to the
body of the lubricator.
Fig. 13. shows a modification in which in the absence of the counterbalancing
pressure, the partition plate I. may be dispensed with and the thrust of the pressure
of the piston on the screw taken by the end plate 7. and the main wheel J. coming
into direct contact with the piston screw shoulder G. this part of our improvement
consists in so arranging the wheel carriage that it may be free to turn on the main
wheel and not be held by the pressure or thrust of the screw which is effected by
the wheel carriage plate, K. taking its bearing and working partly on a boss or
shoulder on the end plate l. and partly on a shoulder on the main wheel and held
in position so as to move freely between the faces of both, while the other part of
the wheel carriage is supported by the plate K' taking its bearing on a shoulder
formed on that end of the main wheel in contact with the screw shoulder G. the
wheel carriage being so arranged that it may be freely turned for bringing the
wheels of the wheel train into working position.
Figs. 14. 15. 16. shews a modification of the index wheel in which instead of
the indexing insterstices being cut on the wheel M. they are cut on the index plate
or stationary index m. and the indications shewn by the spring bolt o. traversing
the index as the wheel M is being turned to operate the wheel carriage by the
pinion L. as hereinbefore described and more particularly shown by Figs. 5. 6. 7. 8.
9. 10 the spindle carrying the pinion L. and wheel M is formed with a screw_n.
working in a nut combined with the spring bolt o. in such a manner that when the
wheel M. is turned the nut travels along the screw carrying the spring bolt so that
it indicates the working of the wheel carriage and the position of the wheels in the
train each of which are represented by the number 1. 2. 3. 4. 5. the spring bolt
being set into any one of the interstices so numbered, sets the wheel of the train
represented by the number of such interstices into gear with the ratchet pinion and
locks the wheel carriage in position for its working.
Fig. 17. represents a modification the object of which is principally to adapt the

page_text: | lubricator to such high speeds as are to rapid for the efficient operation of the ratchet
by substituting the grooved wheel p. and worm and worm wheel q. which are driven
from a convenient rotary motion by a suitable cord working as may be required in
either of the grooves marked 1. 2. 3 each being proportioned so as to divide the
difference of 4 to 1. in the wheels of the wheel train and bear the same relation to
these wheel as is obtained by engaging the pawl of the ratchet motion in one, two,
or three teeth of the ratchet wheel hereinbefore mentioned.
Fig. 18. is a modification adapting the ratchet motion to conditions where it is
more convenient to work it by a rotary than by a rectilienear motion. The combi-
nation consist of combining the crank plate r. with the lubricator and employing it
for operating the ratchet motion and utilizing the movement of the end plate for
regulating the ratchet motion so as to engage the pawl in one, two, or three teeth
by turning and setting the plate to the index 1. 2. 3. so as to increase or diminish
the leverage of the ratchet lever to or from the crank pin working in the slot
formed in the lever as shown, the plate l. is turned or adjusted by slacking the
nut W. so as to free it from the body of the
and it is set or held at the
required position or number shown by the index 1. 2. 3. setting up the nut W. to
its normal position.
Fig. 19. is a modification of Fig. 18. arranging the ratchet motion so that it can
be worked either by a rectilinear or rotary motion which is effected by dividing the.
ratchet lever as shown at s. and s¹ where it is held together by two screws so as to
form a straight lever, when employed for a rectilinear motion and when required to
be operated by a rotary motion the two screws are drawn and s. set back to s¹ and
united by one screw so as to form a joint and convert this part of the lever into
a connecting rod, the other end of which is connected to the pin of the crank
plate r. so as to be operated by it. The adjustment for engaging the pawl in,
one, two or three teeth of the ratchet wheel is the same as Fig. 18.
Figs. 20. 21. shows a modification of the piston screw handle N. in which it is
made in the form of a clutch by the teeth being cut on the end of the boss of the
main wheel J. and counterpart teeth cut on the end of the handle N. which teeth
engage into each other and are held into position by the pressure of the coil
spring 1. which allows the teeth of the handle to slip over those on the main
wheel when the handle is turned in the direction necessary to force the piston
forward for flushing the bearing surfaces and when the piston has to be run back
for recharging the lubricator, as herein before described, the handle N. is drawn
back until the spring catch 2. falls over the collar 3. and locks the handle clear of
the main wheel teeth while it is being turned in the direction for running back the
piston. When the lubricator is charged the spring is released and the screw handle
is again set into gear with the main wheel by the pressure of the coil spring.
The key 4 is provided to prevent the handle from turning on the neck of the
piston screw and the keyway made sufficiently long to allow the handle to slide
over the key.
Figs. 22 & 23 shews a modification in which the segmental rack is formed in the
stationary end plate l. instead of the wheel carriage plate K. which plate is
connected to and carries the wheel M and pinion L. so that when the wheel M is
turned the wheel carriage is operated by the pinion L. gearing into and travelling
over the segmental rack carrying with it the index plate m. which is arranged with
interstices and numbers representing each of the wheels of the wheel train any of
which wheels are indicated and locked into working position by means of the spring
catch M' as herein before mentioned. Fig. 4 on Sheet 1. shows the arrangement
of the press button contact and connecting wires of the electric signal bell in
conjuction with the hollow piston rod D. a. is the press button which is forced
against the spring contact piece b. by the advancing piston rod D. so as to
complete the circuit and set the bell in action by the medium of the positive (c)
and negative (d) wires which are connected with the bell and battery in the
usual manner. The spring e. is so arranged as to provide an elastic pressure
keeping the press button a. and contact piece b. together after the piston rod

page_text: has forced them into contact and giving to the movement of the advancing
piston rod so as to keep the bell in action for a prolonged period.
Fig. 11. Sheet 2. shows the arrangement or modification by which the index
wheel M. is connected directly to the wheel carriage K. K' by fixing the
plate K. to the boss (d) of the said index wheel in such a manner that the
carriage moves with it when it is operated in conjunction with the spring catch M¹
for the purpose of moving round or adjusting and setting the wheel carriage and
train of wheels as herein before mentioned. Fig. 11. further shows a modification
by which the wheel O. is substituted for the screw handle N. the said wheel working
on the screw e. formed on the shank of the piston screw in such a manner that when
turned so as to traverse the screw towards the main wheel J. it jambs the said main
wheel between itself and the shoulder G. so connecting the piston screw main wheel
and automatic mechanism by which it is operated as heretofore described, the piston
screw is freed so as to be worked by hand independently of the automatic mechanism
by turning the wheel O. in the direction that will cause it to relinquish its grip on
the main wheel and advance along the screw to the collar a. against which it jambs
so as to cause the piston screw to move with it in the direction it may be turned for
traversing the piston by hand as heretofore described. Fig. 11. also shows the
arrangement for indicating the displacement of the lubricant or number of revolu-
tions as heretofore mentioned by means of a reduced index plate, C is an index.
hand formed with a nut working in the screw fformed on an extension of the shank
of the piston screw the threads of which are pitched so much finer than the piston
screw that while it is traversing the piston along it from 1. to 6 the index hand C
shows the displacement on a reduced scale from 1 to 6 on the index plate b. Fig. 12
is an end view showing arrangement of index wheel M. and spring catch M'.
Fig. 24, 25 Sheet 4 shews the hereinbefore described arrangement of coiled or
spring pipes connected with the lubricator, crosshead connecting rod bearings
and eccentric Fig. 25 being an enlarged view of the joint A A A A by which
the spring coiled pipes are connected with the stationary lubricator B. and the
bearing surfaces c. c. c. the said joints are connected by means of the screw a.
