Improvements in Apparatus for Applying Lubricators and
Conducting Lubricants to Bearing Surfaces.
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 has for its object improvements in our Patent No. 6913 1892
whereby certain arrangements of mechanism or parts are rendered more efficient
in working or simple of application for small machinery & other lubrication.
For the purpose of assisting the description of our invention we refer to drawings
on Sheet 1. of the aforesaid Patent 6913 by the hereinafter mentioned reference
letters.
And in carrying our invention into practice we combine or form a lubricator
with the oscillating chamber, E, preferably at the trunnions on which it oscillates,
such lubricator operating automatically by being provided with a screw cover or
piston having a number of ratchet teeth preferably around its periphery in two
circles (hereinafter called the first and second circles) the pitch lines or points of
the teeth of the second circle are arranged so as to stand between the pitch lines
or points of the teeth of the first circle so that two pawls (hereinafter called the
first and second pawls) may be alternately acting on them, the said pawls being
arranged so as to have two movements the radial enabling them to slip over the
ratchet teeth and the lateral movement of each of the pins on which they radiate,
which pin obtains such movement by being attached to a sliding bar working in a
suitable bearing so as to be controlled or acted on by a suitable spring which may
be adjustable as also the bar may be by means of a screw and nut. The object of
such spring pressure on the pawl being to offer such an elastic resistance to the
ratchet teeth, when oscillating with the cylinder as to cause the screw piston to
traverse its screw and thereby force the lubricant on which it acts into the bearing
feed pipes, and when one tooth has so altered its position as not to be appreciably
acted on by the spring on the pawl, a tooth in the second circle of teeth owing to
its intermediate position between the teeth of the first is being acted on by the
spring of the second pawl, which in its turn again moves and advances the screw
piston, so as to bring another tooth of the first circle under the action of the first
pawl, so that a tooth of each circle is alternately submitted to the spring action of
each pawl the screw piston is continually thrust round and consequently forward so
as to feed the lubricant to the bearings each pawl may be carried on a radiating
lever or levers acted on by a suitable arrangement of spring pressure so as to
impart the second motion to it instead of by the aforesaid arrangement of
sliding bar.
The said chamber or cylinder, E, may be combined with the lubricator at any
other part of its surface instead of at the trunnions and such lubricator may be
operated by the spring pressure of the herein before mentioned pawls arranged for
operation as may be found convenient or instead of a screw piston a plain piston
or cap may be employed and the lubricant forced or fed from the lubricator by
weight or spring pressure applied to such piston or cap.
The said spring pawls may be operated by a reciprocating motion if found
desirable for some conditions of working.
In another part of our invention instead of connecting the pipe D to the moving
bearing by a joint arranged as shown at G in which the lubricant intended for the
bearing surfaces of the machinery to which it is applied comes in contact with

page_text: the bearing surfaces of the plug or pin formed with the passages, C, (hereinafter
called the pin) and socket forming the joint (connected to and carrying the
pipe, D,) in such a manner that it can work through such surfaces and so
escape, we arrange the said socket on the pin so that it forms no part for
retaining the lubricant but is used as a connection for carrying and operating
the pipe, D, which pipe is formed with a branch pipe so arranged as to be
connected by a union (as hereinafter mentioned) to the pin so as to be free to
move or oscillate with the pipe, D, a longitudinal passage for conducting the
lubricant is formed through the said pin so as to correspond with the bore of
the branch inlet pipe and the exit pipe leading to the bearings with which the said
pin is connected.
By the aforesaid arrangement of parts the escape of the lubricant is prevented
by arranging the aforesaid union with a suitable stuffing box and nut working on a
screw cut on the pin for setting up the packing so as to form a suitable gland.
The socket may be lubricated from the pipe, D, by arranging it with an aperture
leading from it into the pipe so as to form a passage for the admission of a small
quantity of lubricant to the bearing surfaces of the said socket and pin such admission
being regulated by suitable cock or regulating screw. When it is desirable to
conduct the lubricant to moving or other bearings by means of a pipe or conduit
arranged so as to be flexible by means of an intermediate joint (or joints) in order
to avoid the escape of the lubricant through the bearing surfaces of such joint as
aforesaid we arrange or form one pipe or part of the pipe or conduit with a pin
as aforesaid (which may vary in form according to the conditions of working)
having a passage through it leading into and corresponding with the bore of the
pipe with which it is formed such pin working in combination with a socket
connecting it to the other pipe or part from which the lubricant is conducted by a
branch pipe extending from it and connected with the pin by a gland formed union
as herein before described. Instead of branching a pipe from the pipe connected
with the parts and bearing surfaces forming the joints as aforesaid the lubricant
may be conducted by a separate pipe extending from one joint to the other, being
connected with such joints by the aforesaid gland formed unions while the pipe
herein before mentioned as connected with the parts and bearing surfaces forming
the joints acts only as a carriage for supporting the said separate pipe from one
joint to another or from a fixed to a moving joint.
In another part of our invention the pipe, D, is connected with the moving
bearing by means of a cap formed nut (hereinafter called the cap) provided with a
nipple or boss to which the said pipe is connected, the cap is arranged so as to work
on a screw attached to the moving bearing or part the said screw being formed
with an aperture through it for conducting the lubricant from the pipe to the
lubricating channel of the bearing surfaces the said screw is surrounded with a
socket or ring which forms a bearing for the outer surface of the cap and so
relieve the screw from the strain of carrying or working the pipe at the same
time forming a space for containing packing on which the open end surface of the
cap may thrust or which packing may be arranged around the outer surface of the
cap and set up with a suitable gland nut as a provision against the escape of
the lubricant, the threads of the screw on which the cap works are preferably cut
flat or square on one side and bevel on the other and the inner surface of the top
end of the cap may be so formed as to be of a larger diameter than the bore and
present such an increased surface to the pressure of the lubricant as will multiply
the said pressure to an extent that will force the side or flat surfaces of the threads
of the cap and screw together so as to assist in preventing the passage of the
lubricant through or past them. The screw may be extended in the form of a
stud fitting and working into a bearing extended from the top end of the cap, as
an additional support for the relief of the work from the screw. This arrangement
and combination of screw, cap, and parts may be employed as an intermediate
connection for pipe or part working from fixed or moving parts, and as it is
important to insure the proper circulation or distribution of the lubricant more

page_text: especially soft grease or that of a solid or semi solid nature requiring mechanical
force to circulate it through the feed pipes or lubricating channels we arrange,
combine or form the aforesaid joints, unions, connections, or parts, employed for
conducting the lubricant, with an aperture or apertures sealed with a screw or
movable plug or plugs, which admit of the said aperture or apertures being
temporally opened for testing or indicating if the lubricant is in proper circulation
by its outward flow from such apertures, instead of disconnecting parts of the
conducting system for such observation, for the same purpose (as may be required)
we also combine or form the aforesaid aperture and screw or movable plug with
the regulating cocks or valves employed in combination with the parts aforesaid
for regulating the passage and distribution of the lubricant through the conducting
system.

Improvements in Apparatus for Applying Lubricators and
Conducting Lubricants to Bearing Surfaces.
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 has for its object improvements in our Patent No. 6913, 1892
whereby certain arrangements of mechanism or parts are rendered more efficient in
working or simple of application for small machinery and other lubrication.
For the purpose of assisting the description of our invention we refer to drawings
on Sheet 1 of the aforesaid Patent 6913 by the hereinafter mentioned reference
letters.
And in carrying our invention into practice we combine or form a lubricator
with the oscillating chamber, E, preferably at the trunnions on which it oscillates
such lubricator operating automatically by being provided with a screw cover or
piston having a number of ratchet teeth preferably around its periphery in two
circles (hereinafter called the first and second circles) the pitch lines or points of
the teeth of the second circle are arranged so as to stand between the pitch lines or
points of the teeth of the first circle so that two pawls (hereinafter called the first
and second pawls) may be alternately acting on them, the said pawls being
arranged so as to have two movements the radial enabling them to slip over the
ratchet teeth and the lateral movement of each of the pins on which they radiate,
which pin obtains such movement by being attached to a sliding bar working in a
suitable bearing so as to be controlled or acted on by a suitable spring which may
be adjustable as also the bar may be by means of a screw and nut. The object of
such spring pressure on the pawl being to offer such an elastic resistance to the
ratchet teeth when oscillating with the cylinder as to cause the screw piston to
traverse its screw and thereby force the lubricant on which it acts into the bearing
feed pipes, and when one tooth has so altered its position as not to be appreciably
acted on by the spring on the pawl, a tooth in the second circle of teeth owing to
its intermediate position between the teeth of the first is being acted on by the
spring of the second pawl, which in its turn again moves and advances the screw
piston, so as to bring another tooth of the first circle under the action of the first
pawl, so that a tooth of each circle is alternately submitted to the spring action of
each pawl the screw piston is continually thrust round and consequently forward so
as to feed the lubricant to the bearings each pawl may be carried on a radiating
lever or levers acted on by a suitable arrangement of spring pressure so as to

page_text: impart the second motion to it instead of by the aforesaid arrangement of
sliding bar.
The said chamber or cylinder E may be combined with the lubricator at any
other part of its surface instead of at the trunnions and such lubricator may be
operated by the spring pressure of the hereinbefore mentioned pawls arranged for
operation as may be found convenient or instead of a screw piston a plain piston or
cap may be employed and the lubricant forced or fed from the lubricator by weight
or spring pressure applied to such piston or cap.
The said spring pawls may be operated by a reciprocating motion if found
desirable for some conditions of working.
In another part of our invention instead of connecting the pipe D to the moving
bearing by a joint arranged as shown at Patent 6913 aforesaid, in which the
lubricant for the bearing surfaces of the machinery to which it is applied comes in
contact with the bearing surfaces of the plug stud or pin formed with the passage (c)
(hereinafter called the hollow pin) and socket or bearing forming the joint
(connected to and carrying the pipe D) in such a manner that the lubricant can
work through such surfaces (especially when they become worn) and so escape, we
arrange the said socket on the hollow pin so that it forms no part for retaining the
lubricant but is used as a connection for carrying and operating the pipe D which
pipe is formed or connected with a branch pipe so arranged as to be connected by
a union (as hereinafter mentioned) to the hollow pin so as to be free to move or
oscillate with the pipe D the said pin is formed hollow with a longitudinal passage
for conducting the lubricant through it such passage being dimensioned so as to
correspond with the bore or diameter of the branch inlet pipe and the exit pipe
leading to the bearings or bearing surfaces with which the said hollow pin is
connected.
By the aforesaid arrangement of parts the escape of lubricant is prevented by a
union aforesaid arranged by forming the hollow pin with a suitable stuffing box
provided with a gland or gland nut (hereinafter called the gland) working on or
in a screw cut on or in the pin for setting up the packing so as to form a suitable
gland and packing tight connection-The socket may be lubricated from the
pipe D by arranging it with an aperture leading from it into the pipe so as to form
a passage for the diversion or admission of small quantity of lubricant to the
bearing surfaces of the said socket and hollow pin such admission being regulated
by a suitable regulating screw or cock-When it is desirable to conduct the
lubricant to moving or other bearings by means of a pipe or conduit arranged so as
to be flexible by means of an intermediate joint (or joints) in order to avoid the
escape of the lubricant as aforesaid through the bearing surfaces of such inter-
mediate joints we arrange or form one pipe or part of the flexible pipe or conduit
with a hollow pin as aforesaid (which may vary in form and or arrangement
according to the conditions of working) having a passage through it leading into
and corresponding with the bore of the pipe or part with which it is formed such
pin working in combination with a socket (sockets or bearings) formed with or
connected to the other part of the pipe or conduit (hereinafter called pipe) or
part D which is formed or connected with a branch pipe (or pipes) extending from
it to the hollow pin and connected with it by a stuffing box, packing and gland (as
hereinbefore mentioned). This combination of branch pipe hollow pin and parts
forming an intermediate joint connecting the two pipes or parts by their ends so
that the lubricant may be conducted from one pipe or part to the other pipe or
part by means of their connection with the hollow pin branch pipe and pipe or
part D the other end of which is connected to the moving bearing to be lubricated
by a joint arranged in the same manner as the first herein mentioned pipe D while
the other pipe or part has its end extending from the intermediate joint connected
with a similar joint to that connecting with moving bearing on which similar
joint it is carried and radiates on as a fixed point the said joint being carried by a
bracket fixed to the framing or stationary part of the machinery to be lubricated-
the hollow pin of this last mentioned joint admits of its being connected with the

page_text: feed pipe leading from the lubricator or source of supply so that the lubricant
passing from the feed pipe continues its passage through the hollow pins branch
pipes and other pipes or parts connected with each joint until it is conductel to the
moving bearing or bearing surfaces by the said combination or flexible pipe or
conduit operating with or following them in their action.
The pipe or part radiating on the fixed point instead of being formed with the
hollow pin (as aforesaid) may be formed or connected with a fork arranged with
sockets or bearings so that the joint may be formed by passing the hollow pin
through such sockets or bearings and the socket connected with the intermediate
joint end of pipe, D, when they are arranged in proper relation to one another, and
in order to conduct the lubricant to the hollow pin a branch pipe is formed or
connected with the aforesaid radiating pipe or part and extended to and connected
with hollow pin by a stuffing box packing and gland as provided at its other end
for connection with the branch pipe leading from it to pipe D other modification or
arrangement of hollow pin, sockets or bearings and parts may be made so as to
adapt them to various working conditions. Instead of branching a pipe from the
pipe or part D and other pipe or part forming the flexible pipe or conduit as
aforesaid the lubricant may be conducted by a separate pipe extending from one
joint to another being connected with such joints by the aforesaid hollow pin,
stuffing box packing and gland while the pipe or part D and other part radiating
on fixed point act as a carriage (to which the separate pipes may be held by clips)
for supporting, holding, or operating the said separate pipes while they are
conducting the lubricant from one joint to another or from a fixed to a moving
joint. This arrangement of separate pipes in substitution for the branch pipes is
more simple and facilitates their removal as conduits-rendering their more
accessible and allows more spring for giving to the joints in the event of undue
wear from neglect or necessity.
In another part of our invention the pipe, D, is connected with the moving or
movable bearing (or bearings) by means of a cap formed part (hereinafter called
the cap) arranged and formed in various ways and with special surfaces and
connections for preventing leakage or waste of the lubricant while it is conducting
it to the bearing surfaces with which it is connected such connection being effected
by a hollow pin formed at one end with a flange or screw by which it is attached
to the said bearing from which it extends to receive the cap such extension being
formed by a screw with threads of form or section (as hereinafter described)
similar threads being formed on the internal surface of the said cap so that it may
be screwed on or traverse a sufficient number of threads on the said hollow pin
to ensure its resting on adequate bearing surface supporting and retaining it in
position when working with the moving bearing or pipe or tube, D, and when
found necessary to relieve the screw of the strain of wholly supporting and
working the pipe D a socket or ring is extended on the screw from a flange or
boss on the hollow pin which surrounds and forms a bearing for the outer surface
of the cap at the same time providing a space for containing packing on which
the open end surface of the cap may work or thrust, or the aforesaid socket or
ring may be formed with a space for containing packing so that it may surround
the outer surface of the cap and be set up or compressed on such surface with a
gland provided for the purpose, thus offering additional security against the escape
of the lubricant which is one of the objects of the aforesaid screw cut or formed on
the surface of the cap and hollow pin the threads of such screw being flat or
square on one side and bevelled on the other so as to form a series of flat rings
surfaces which surfaces in contact collectively present a considerable surface for
resisting the escape of the lubricant, the said cap may be so formed as to be of a
larger diameter than the bore and present such an increased surface to the pressure
of the lubricant as will multiply the said pressure to an extent that will force the
side or flat surfaces of the threads of the cap and screw together so as to assist in
preventing the passage of the lubricant through or past them. The screw may be
extended in the form of a stud fitting and working into a bearing extended from

page_text: Sheet 1 Fig. 1 is a side elevation showing in section spring mechanism acting on
pawls. Fig. 2. end view. Fig. 3. sectional plan. Fig. 4. plan showing lubricator
and mechanism in combination with cylinder E.
A is the screw cover or piston arranged with two circles of ratchet teeth B
and C around its periphery so arranged that the teeth of the second circle Care
arranged or pitched so as to stand between the pitch lines or points of the first
circle B-so that two pawls the first F and the second G may be alternately
acting on them, the said pawls having two movements the radial enables them to
slip over the ratchet teeth and the lateral movement of each of the pins H and I
on which they radiate, which pins each obtain such lateral movement by being
connected with the sliding bars J and K working in the slides or bearings L and M
so as to be each controlled or acted on by a spring as at N Fig. 1, so as to offer
such elastic resistance through the medium of the pawls to the ratchet teeth when
oscillating with the cylinder as to cause the screw cap or piston to turn and traverse
the screw and by such action press on or force the grease or lubricant contained
in the space P. (formed in the cap for its reception) through the aperture (a) into
the channel Q and cylinder, E, from which it continues its passage to the bearing
feed pipes in the manner described in the herein before mentioned Specification
No. 6913, the pressure on the lubricant being kept up by the alternate action of
the ratchet teeth on the pawls when one tooth in the circles B. has so altered its
position (by thrusting on the pawl, F) as not to be appreciably acted on by the
spring of the said pawl, a tooth in the second circle, C, owing to its intermediate
position between the teeth of the circle, B, is being acted on by the spring of the
second pawl, G, which in its turn moves or advances the screw cap or cover, A, so
as to bring another tooth of the circle, B, again under the action of the first pawl, F,
so that a tooth of each of the circles B. and C. is alternately submitted to the
spring pressure of each pawl and the screw cap or cover, A, thereby continually
thrust round and forwarded on the screw O so forcing the grease out of the space P.
(as hereinbefore mentioned). Any number of fixed bearings may be connected
with the pipe, R, for lubrication according to the capacity, screw cap and parts
forming the lubricator the said pipe is connected to the cylinder, E, by a gland
union so as to allow for the motion of the cylinder and to prevent leakage around
the pipe.
Sheet 2. Figs. 1. 2. 3. 4 & 5 show arrangements of parts for forming flexible
pipes or conduits by various adaptations or modification of the joint formed by
combination of the branch pipe B with pipe D. and other moving or movable
conducting pipes, hollow pin, and parts, herein before described.

page_text: Fig. 1. shows a plan of pipe D and cylinder E with part of the pipe, and th>
joint in section. A. is a casting forming socket, (a.) and connection at 6 and c
with pipe D and branch pipe B which branch pipe is also connected with the hollow
pin C by means of the gland (d) stuffing box (e) and packing (f) which holds and
surround the branch pipe so as to practically prevent leakage of the lubricant and
admit of its free passage or conduction from the pipe D through branch pipe B
into the passage g. through hollow pin at the same time admitting of the free
movement or radiation of the said branch pipe with the pipe D while it is moving
with the bearing or machinery with which the hollow pin may be connected by
the screw or flange at its end (4) where its passage or outlet (g) is also connected
with the feed pipes, conduits or other passages arranged for conducting the
lubricant from it to the bearing surface of the machinery to be so lubricated.
Fig. 2. shows the part forming the aforesaid joint modified or adapted as an
intermediate joint (or joints) where it may be necessary or desirable to employ a
flexible pipe or conduit for conducting the lubricant to moving or movable bearing
or bearings, the part forming the socket, a, and connections b and c are arranged at
both ends of the pipe D and for the purpose of obtaining a more suitable
distribution of the bearing surface the socket, a, is divided into two bearings, a. a.
formed with a fork the hollow pin is formed or arranged on the other part of the
conduit identified as pipe D¹ so as to work or radiate with it and is provided with
gland d stuffing box, e, and packing, f, for connecting it (the said pin) with the
branch B leading from the pipe D to which it is connected by a connection or
union c the pipe F is connected with the lubricator or source of supply, and the
lubricant intended for conduction to the moving or movable bearings passing
from F makes its passage through the hollow pin (on which the pipe D₁ radiates,
which pin forms part of a joint hereinafter called the stationary joint) to the
branch pipe B by which the lubricant is conducted to the pipe D¹ to which the
said branch pipe is connected by the connection or union c forming also its
connection with the hollow pin by the gland stuffing box and packing as described
at Fig. 1, the lubricant continuing its course through pipe D¹ makes its passage
through the hollow pin C (forming part of the intermediate joint through which
it passes) to the branch pipe B of the aforesaid joint by which it is connected to
the pipe D and through it to the hollow pin C which conducts it to the pipes or
conduits leading to the bearing surface of the moving or movable bearing with
which the said pin is connected.
The aforesaid arrangement and combination of parts with the arrangement of
intermediate joint between the two connections with the machinery (one connection
being stationary hereinbefore called the stationary joint, and the other connection
to moving bearing) form a flexible pipe or conduit working with the hereinbefore
mentioned advantages while following the movements of the said bearings and
conducting lubricant to their bearing surfaces while in operation-any number of
intermediate joints may be arranged between the two connections with the
machinery as aforesaid according to the design of the machinery or the location
or movement of the bearings to be lubricated.
The aperture or passage i and j. the regulating screw for admitting and regulating
the diversion of a small quantity of the lubricant to the bearing surface of the
socket, a, and pin C may be similarly arranged for the same purpose with the
sockets or bearing surfaces of similar joints showing in Figs. 1. 3. 4. and 5.
Fig. 3 and 4 differ in arrangement from Fig. 2, inasmuch as the pipes
marked B instead of branching from the pipes or parts of the conduit D and D¹
extend from joint to joint forming a separate and independent conduit between the
said joints as identified by the arrows between the reference letters B B for
indentifying the said pipe which are hereinafter called the separate pipes-the
pipes or parts D and D₁ simply form part of the mechanism carrying and operating
the separate pipes while they are conducting the lubricant from joint to joint for
conduction to the moving or movable bearing surfaces and for this arrangement
the said pipes D and D' might be substituted by solid rods excepting their

page_text: lightness makes them preferable connections for the joints with which the separate
pipes are connected by the hollow formed pins with stuffing boxes, packing and
glands for the purpose of such connection which is similar to that described for
branches B at Fig. 2.
In the intermediate joint the hollow pin is not formed on the pipe or part D' as
in Fig. 2, but instead D' is arranged at this part with a fork formed with two
sockets or bearings, a a, connected with socket a arranged on pipe D with which it
is connected by the hollow pin C passing through both in such a manner that the
said pin is free to move in them so as to be subject to more uniform wear than
when formed with D' as in Fig. 2, the end of the pipe or part D' extending from
the intermediate joint is arranged with a socket for connection by hollow pin C
with two bearings formed or carried by the bracket G by which it is bolted to or
connected with the framing or stationary part of the engine (or machinery for
which it may be required) so that the said hollow pin forms the fixed point on
which D radiates carring the intermediate joint and pipe or part D while they
are operating with and following the moving bearing.
In some cases the design or location the moving or movable bearing or bearings
to be lubricated may require to be connected with two separate conducting pipes
this is provided for by the modification shown at Fig. 5, in which the hollow pin C
is formed on pipe or part D' and arranged with stuffing box, gland and packing at
each end so that the two separate pipes B B may be connected with the said pin
(as herein before mentioned) the passage through which pin conducts the lubricant
to them from the pipe or part D¹ for conduction to the moving or movable bearing
or bearings with which they may be connected to or operating with the bracket G,
bearings, hollow pin, socket and part represent the stationary joint referred to at
Fig. 2, which holding the hollow pin as a fixed point admits of its connection with
the stationary supply pipe F as aforesaid.
Sheet. 3. Fig. 1. shows in sectional plan the arrangement of a flexible conduit
with pipe or parts, connected with cap joints as herein before described.
Fig. 2 is a sectional view of cap joint connected with pipe, D, showing bearing
extended from its closed end for extension formed on the hollow pin or screw.
Fig. 3 shows the modification or adaption of Fig. 2. as an intermediate joint
connecting two pipes or parts D and D' of a flexible conduit. Fig. 4 shows an
example of application of Figures 2. and 4 Sheet 2 to some of the moving bearings
of an engine.
In Fig. 1. A represents joint for connection to the crosshead of an engine or
other moving bearing, B. the intermediate joint, C. the stationary joint or joint
connected with the framing or stationary part of the engine or machinery forms or
forming the fixed point on which pipe D₁ radiates operating with and carrying the
end of pipe connected with A, in which a. represents the cap flat sided screw threads
(as hereinbefore mentioned) by which it is connected with an indentical screw b,
formed on the hollow pin c. d. is a socket or ring surrounding part of the outer
surface of the cap so as to form an additional bearing for the relief of the hollow
pin and screw with space containing packing, e, to be compressed by the contact or
thrust of the open end surface so forming an additional provision against the
leakage of the lubricant 9. is the passage through the hollow pin to which the
lubricant is conducted by it to the bearing surfaces or lubricating conduits of such
surface when connected to them by the screw or flange, h. The aforesaid reference
letters indicate the same parts in B and C except g and h, g being modified in B
in the adaptation of the parts as an intermediate joint and h. not required in the
modification of both B. and C in B. g is continued as a passage conducting the
lubricant round to the nipple or union i formed on the aforesaid socket for connection
of the joint with the pipe D into which the passage g. opens and which conducts
the lubricant to it from the cap, a, as it enters it from the pipe D' through the
passage g¹ which is a modification with nipple or union, j, provided for connection
with pipe which is arranged with a bracket, n, working in conjunction with a stud, o,
in the end of joint so as to equalize the bearing or support the joint when adapted

page_text: and acting as an intermediate joint-The pipe D₁ is connected with the cap
stationary joint C. by a similar modification a nipple or union k and passage g³
leading into the cap and conducting to pipe 'D', the lubricant entering it
through the passage from the conducting or supply pipe 1, connected with
and leading to the lubricator or source of supply from which it will be
seen the lubricant is conducted through C pipe or part D' B. pipe or part D
to A by which it is conducted to the before said moving bearing surfaces
while they are in motion, the flexible pipe or conduit formed by A. B. C
working with the said moving bearing and following it in its action while the
pressure of the lubricant (when forced under pressure) acts on the enlarged
surface m. of the cap so as to be utilized as a medium for keeping the
series of flat circular surfaces (formed by the screw thread) in contact with a
force according to the pressure of the lubricant multiplied by the extent of the
increased area of the enlarged surface m.
Fig. 2. is this modification the references of A Fig. 1. are applicable in
differing only in the absence of the enlarged surface and in the extension of a
bearing, n, from the cap to receive the extension, o, of the hollow pin or screw the
pipe D. being connected to the extension of the cap by the nipple or union for
connection (as shown) with pipe D. Fig. 3. is a modification of Fig. 2. forming it
as an intermediate joint for connecting the pipe or parts of a flexible conduit as
aforesaid and differing from Fig. 2 by the socket or ring d. being formed so as to
contain packing, 1, encircling the outer surface of the cap on which the said
packing is set up or adjusted by the gland, g, so forming an external provision
around outer surface of the cap against leakage also the passage, y, differs
from Fig. 2. by being branched round to the union r. for connection with the
pipe D' such branch with a bracket bearing, s, carrying the extension of the cap
for the better equalization of the working strain with exception of those
modifications the reference letters of Fig. 2. are applicable to this figure which is
employed as a substitute for B. in Fig. 1. as may Fig. 2 for A. if desirable.
Fig. 4. Sheet 3. shows an example of Fig. 3. Sheet 2 applied to the crosshead
bearing of an engine at, A in connection with conducting pipe leading to the
crank pin so that the lubricant being forced from the lubricator passes through
hollow pin C. into separate pipe leading to hollow pin at B. by which it is
conducted to the separate pipe e. connected with the hollow pin at A. whereby its
connection with the conducting pipe leading to the crank pin admits of its passage
to and through the said pipe so as to lubricate the crank pin bearings surface while
in motion, the eccentric is being at the same time similarly lubricated by the
lubricant passing from the lubricator and conducted by Fig. 2 Sheet 2.
Sheet 4. Fig. 1 & 2 shows an example of the arrangement of test cocks in
combination with the bearings and lubricant conducting pipes leading from the
