"In Figures 1 to 3, A¹ indicates a condensing chamber connected with the
steain pipe S which at the branch St connects with the steam boiler. A* indicates
an oil and water chamber which connects with the upper condensing chamber A'
by means of the connecting pipes d¹ and do, there being arranged between these
pipes the valve V. B indicates an opening and plug in the chamber A³ for
supplying oil to the same, and P indicates a small cock for drawing off the
water from this chamber A³. With this latter chamber at its top is connected 5
the oil pipe O' on which is placed the valve Vs, and at Os this pipe leads down-
wardly into a glass tube G the latter being placed within the pipe P' which has
constructed on opposite sides sight openings n through which the descending oil
may be seen. The oil pipe Os terminates in a pendant nozzle having a button
on the pipe also upon the pendant discharge end. Within the chamber A' there 5
is a steam pipe Ss opening into this chamber, so as to receive steam under

<
pressure therefrom.
This steam pipe S³ passes downwardly through the
condensing chamber A¹ into the cored arm pipe P₁ at St where it connects with
"the annular chamber a formed in the said pipe, and from which the steam under
pressure is forced through the glass tube G, being deflected to the sides of the
"latter by the flat ring on the oil pipe Os, above the discharge pendant nozzle end
"of the latter. From this point the dropping oil and the steam pass downwardly
"and around the three-sided stem of the poppet valve n within the oil conduit
pipe O, and from thence into the annular space S7 in the horizontal pipe P',
"from which it passes into and through the conduit pipe 06, which connects with
"the steam cylinder.
"
"
"
"To protect the glass tubes of the lubricators through which the oil and steam
passes, I surround them with the protecting pipe P2, which has oppositely
arranged sight openings no, no and combine with the latter a clamp constructed
"with the stopper plugs no n³ and the screw and thumb piece W so that in case
"the glass tube becomes broken the lubricator may be temporarily used without
"the tube until the latter is replaced. To prevent any unusual back pressure from
"the steam cylinders and the consequent churning up of the oil and water so as
"to interfere with the uniform flow and delivery of the oil from the lubricator
vessel, I arrange within the oil delivery pipe O, the poppet valve n, the stem of
"which is three sided so as to allow a passage along the stem, and between it and
"the sides of the pipe supplying the oil to the conduit pipe leading to the steam
cylinder. The button of the valven seating to close the pipe O', in the rounded
top n, of the annular chamber S7, which forms the outlet of the latter pipe,
"when any unusual pressure from the cylinder causes the valve to rise and thus
"close.
"
"

"
«
"
"When steam is shut off from the steam cylinders of a locomotive as is the case
"when the latter is descending an incline, the vacuum tendency produced in the
"steam cylinders draws the oil from the lubricating vessels so as to sometimes
empty them. To avoid this difficulty I connect the oil conduit pipe leading to
the steam cylinders directly with the boiler, by which this tendency is relieved.
This auxiliary pipe e² at its upper end connects with the steam pipe S¹, and its
"lower end e opens into the oil conduit pipe 0; part of the arm P being cored
"out to form a continuation of the pipe c². While I have shown this improved
"feature of an auxiliary steam pipe connecting the oil conduit pipe that leads to
"the cylinder, as applied to a duplicated lubricator each of which two connects
separately with one of the steain cylinders, it may be applied in the same manner
" and so as to perform the same useful office to each of the branch cylinder connec-
"tions made with a single lubricator.
"
"The condensing chamber A¹ serves to collect water and receive pressure from
the steam boiler by means of the pipe S2, and the received pressure and accu-
"mulated condensation it transmits to the lower chamber A2 through the pipes d¹
"and do, the amount of water delivered and steam pressure transmitted to the
"lower chamber A being regulated by the intermediately placed valve VI
"
"The position of the water in the upper and lower cylinders being indicated at
"a³, and that of the oil in the lower chamber at O, it is obvious that the oil would
"flow from the lower chamber under the steam pressure communicated from the
"chamber A¹ were there no water in the latter, and the function of the water in
"the lower chamber A would be merely to float the oil so as to have it overflow
through the delivery pipe 0³, hence the steam pressure upon the upper chamber
"is an important factor, and the water in the upper chamber, except as a source of
supply through the regulating valve to float the oil, a secondary one so far as
hydrostatic pressure is concerned from above and independently of the steam
pressure exerted upon it. By thus constructing the lubricating device, so as to
"take steam from the interior of the chamber A' through the pipe S3 with which
"to force the delivery of the oil towards the point of its use, and thus connecting
this chamber A' with the chamber A² to utilize this same steam pressure to
"
(t

page_text: "
supply water to and to force the overflow of oil from the chamber A³, a single steam
"connection with the lubricator is made to perform several important uses within
"the lubricator, in a manner and by a means of construction which ensures
uniformity of pressure within the lubricator and a regular delivery of oil
".
"therefrom.
"The two lubricating vessels X and X, X have a branch connection S² which
"connects them at S¹ with the boiler, and each of them is a duplicate of the other
" and has a conduit pipe to connect it separately with one of the steam cylinders.
"This branch connection for supplying the interior of each lubricator with steam
" for the purpose hereinbefore named and described, is also branched to supply an
auxiliary steam pipe connection with the conduit pipes of each lubricator, so that
"a single tube connection made at S' operates both of them.
"

"
«
"
Referring to Figures 4 to 9 of the drawing A indicates a glass cup or reservoir
"formed with a neck A¹ and adapted to contain a suitable quantity of lubricant,
" as usual.
B indicates an externally screw threaded collar which is fitted upon
"the neck of the cup and adapted to couple with a nozzle designed to be detachably
" connected with the said threaded collar, in order that it may be removed when
" it becomes necessary to introduce a fresh supply of lubricant into the cup. In
"the present instance the nozzle C comprises an externally screw threaded
nipple C', having at its upper end an internally screw threaded cap C², provided
" with a suitable packing ring D, the cap being adapted to be screwed up on
"the collar that is fitted to the neck of the cup, and the screw threaded nipple
being adapted for attachment to engines or other mechanism to be lubricated.
"In turning either the cup or the nozzle for the purpose of detachment, the
glass neck will turn in the collar that is fitted thereon, or the collar will be
" turned upon the said neck unless means other than the merc frictional contact
"between the neck and the collar are provided. Also the same difficulty will be
experienced in screwing up the screw-threaded cap of the nozzle, since an attempt
" to rotate the cap will cause the collar to turn upon the neck. In order therefore
"to render the collar rigid upon the glass neck and thereby prevent the cup and
"the collar from turning independently of each other, I form the glass cup with
a groove E, which extends around the said cup from end to end, and has its
"terminals in the neck at or near the edge of the same, and into the said groove
"I fit the retaining wire F which is connected at its ends with the ring or collar B.
"This retaining wire, which is thus applied along two sides and across the solid
"end of the cup, is drawn down snugly into the groove so as to bind firmly upon
" the cup, and is secured to the inner face of the ring or collar by solder, rivets,
" or analogous means. In addition to the grooves in the neck which receive
"the ends of the wire, the collar might be correspondingly grooved or notched
" in its inner face, so that a portion of the said wire will also be received in the
grooves or notches of the collar which arrangement would serve as an auxiliary
"to the collar or rivets employed.
"
"
"
"
"The rod G illustrated in several of the figures is the same as one heretofore
employed in this class of oil cups and is designed to fit loosely within the nozzle
and project both between and above the same, so as to enter the oil cup and
"rest upon the journal over which the cup is placed, in order to automatically
"cause the flow of oil during the operation of the machine or engine to which the
" oil cup is attached.
"
"It will be evident that it will not be necessary to make the groove continuous
" around the glass cup from one side of its neck to the opposite side of the same,
since, for example, the groove could be discontinued at that end of the cup which
" is opposite to the one provided with the neck. Again in lieu of the groove in
"the body of the cup the latter might be formed with two lines of lugs or
projections, between which the wire could be placed and held. Also more than
"one retaining wire may be employed if preferred.
"
Having thus fully described the said invention as communicated to me by

page_text: my foreign Correspondent and the manner of performing the same, I wish it
understood that I claim :-
“First. In a lubricating device connected with a steam-boiler so as to receive
pressure therefrom, the internally arranged pipe S³ open at its upper end, and its
horizontal connection S* formed with the annular space a in the pipe P¹, as, and
for the purposes, herein described.
"Second. The combination, with the glass tube of a lubricating device, of an
externally placed protecting pipe, constructed with oppositely arranged openings
through which to observe the flow of oil through the pipes, a clamp constructed
with oppositely arranged plugs, and a thumb screw for securing the said plugs
within the sight openings of the external protecting pipe, substantially as shown
and described, and for the purpose specified.
"Third. In a lubricating device, the combination of the poppet-valve n, the oil
"exit pipe O, and the valve seat n formed in the chamber S', substantially as
"shown and described, and for the purpose specified.
Fourth, The combination, with the glass oil-cup, of the externally screw-
"threaded collar fitted upon a grooved neck of the cup, the retaining wire held
upon the cup having its ends received on the grooved portions of the neck and

"collar thus secured, substantially as described, and for the purpose specified."
In witness whereof I the said William Robert Lake, have hereunto set my
hand and seal this Fifteenth day of June in the year of our Lord One
thousand eight hundred and eighty three.

LETTERS PATENT to William Robert Lake, of the firm of Haseltine, Lake,
& Co, Patent Agents, Southampton Buildings, London, for an Invention of
IMPROVEMENTS IN LUBRICATING APPARATUS FOR STEAM ENGINE CYLINDERS
AND OTHER PARTS OF MACHINERY Communicated to him from abroad
by Timothy Holland, of Troy, New York, United States of America,

"
PROVISIONAL SPECIFICATION left by the said William Robert Lake at the
Office of the Commissioners of Patents on the 15th August 1882.
FOR STEAM ENGINE CYLINDERS
WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake and Co., Patent Agents,
Southampton Buildings, London, "IMPROVEMENTS IN LUBRICATING APPARATUS
"
AND OTHER PARTS OF MACHINERY [A com-
munication to him from abroad by Timothy Holland, of Troy, New York; United
States of America, Manufacturer.]
The first part of this Invention relates to that class of devices termed lubricators
which are used to contain and supply material for lubricating the working parts of
machinery; and the object of my improvements are to better adapt such devices
for use upon locomotive engines.
The second part of the said Invention relates to that class of lubricators which
comprise a glass or other transparent cup or reservoir for containing the oil or
other lubricating material, having a detachable nozzle adapted to be secured in a
suitable socket provided in or on a journal-box, or other part of machinery.
The first part of the said Invention consists partly in a lubricating vessel
containing an oil and water chamber connected with a steam boiler so as to receive
steam pressure therefrom, and constructed to deliver oil to a conduit pipe, and a
conduit pipe to connect said lubricator with one of the steam cylinders of a
locomotive, and a steam-pipe connecting said conduit pipe with the steam boiler..
The first part of the said Invention also consists partly in a steam-pipe connecting
with a glass or other transparent tube to force the descending drops of lubricant
through the latter, and a conduit-pipe, and a steam-pipe connecting the conduit-pipe
with the boiler

page_text: The first part of the said Invention further consists partly of an upper chamber
connected with the steam-boiler, a lower oil and water chamber connected with
the upper chamber by a pipe and provided with an oil overflow outlet near its top
having a pendant discharge-nozzle and an intermediate valve on the pipe con-
necting the two chambers to regulate the steam pressure upon the oil and water in
the lower chamber and the flow of condensation from the upper chamber thereto.
The first part of the said Invention further consists partly in combining with the
glass tube, a lubricating device, and exterior protecting pipe constructed or provided
with oppositely arranged sight-openings through which to observe the flow of oil
through the pipes, and a clamp having oppositely arranged plugs, and a screw to
secure the plugs within the sight-openings of the protecting pipe.
The first part of the said Invention embraces other features which will be
hereinafter described.
The second part of the said Invention consists partly in an oil cup or reservoir
provided with a neck and an externally threaded collar for engaging a detachable
nozzle, the collar being secured against rotation upon the neck by a retaining wire
which is passed around the cup.
The second part of the said Invention further consists partly in an oil cup or
reservoir provided with a neck and having an externally threaded collar for
engaging a detachable nozzle, said collar being rigidly held upon the neck by a wire
which passes around the cup and is secured at its ends to the collar.
The second part of the said Invention further consists partly in an oil-cup
formed with a projecting neck, and upon its opposite sides with a groove extending
along the said neck and terminating at, or near, the edge thereof, said grooves being
adapted to receive a retaining wire for attaching a metal collar upon the neck and
preventing its rotation.
The second part of the said Invention embraces other features which will be
hereinafter described.
In carrying the first part of the said Invention into practice I provide two
lubricating devices which are constructed alike and connected. Each one is
constructed as hereinafter described, that is to say, I provide a condensing chamber
which is connected with a steam pipe which, at a branch, connects with the steam-
boiler. There is an oil and water chamber, hereinafter called the lower chamber,
which connects with an upper condensing chamber by means of connecting pipes;
there being arranged between these pipes a valve. An opening and plug are
provided in the lower chamber for supplying oil to the same and there is a
small cock for drawing off the water from this chamber. From this latter
chamber, at its top, is connected the oil pipe on which is placed a valve, and this
pipe leads downwardly into a glass tube the latter being placed within a pipe
which has constructed on opposite sides sight openings through which the
descending oil may be seen. The oil-pipe terminates in a pendant nozzle having
a button upon the pipe also the pendant discharge end. Within the upper chamber
there is a steam-pipe opening into this chamber so as to receive steam under
pressure therefrom. This steam pipe passes dowbwardly through the condensing
chamber into a cored arm pipe where it connects with an annular chamber formed
in said pipe and from which the steam, under pressure, is forced through the glass
tube, being deflected to the sides of the latter by a flat deflecting ring on the oil-
pipe above the discharge pendant nozzle end of the latter. From this point the
dropping oil and the steam pass downwardly and around the three sided stem of a
poppet valve within an oil-conduit-pipe, and from thence into an annular space in a
horizontal pipe from which it passes into, and through, a conduit-pipe which
connects with the steam-cylinder.
To protect the glass tubes of the lubricators through which the oil and steam
move, I surround them with the protecting pipe which has oppositely arranged
sight openings, and combine with the latter a clamp constructed with stopper plugs
and screw and thumb piece so that in case the glass tube becomes broken the
lubricator may be temporarily used without the tube until the latter is replaced.

page_text: To prevent any unusual back pressure from the steam-cylinders and the consequent
churning up of the oil and water so as to interfere with the uniform flow and
delivery of the oil from the lubricator vessel, I construct, within the oil delivery
pipe, the poppet valve the stem of which is three sided so as to allow a passage
along the stem and between it and the sides of the pipe of the oil being supplied to
the conduit pipe leading to the steam cylinder. The button of this valve seating
to close the pipe in the rounded top of the annular chamber which forms the outlet
of the latter pipe, when any unusual pressure from the cylinder causes the valve to
rise and thus close.
When steam is shut off from the steam-cylinders of a locomotive, as is the case
when the latter is descending an incline, the vacuum tendency produced in the
steam-cylinders draws the oil out from the lubricating vessels so as to sometimes
empty them. To avoid this difficulty I connect the oil-conduit-pipe leading to the
steam-cylinders directly with the boiler by which this tendency is relieved. This
auxiliary pipe, at its upper end, connects with the steam-pipe and its lower end
opens into the oil-conduit-pipe; part of an arm being cored out to form a
continuation of the said pipe.
While I have described this improved feature of an auxiliary steam pipe con-
necting the oil conduit pipe that leads to the cylinder, as applied to a duplicated
lubricator, each of which two connects separately with one of the steam-cylinders,
it may be applied in the same manner, and so as to perform the same useful office,
to each of the branch cylinder connections made with a single lubricator.
The condensing chamber serves to collect water and receive pressure from the
steam-boiler by means of a pipe, and the received pressure and accumulated con-
densation it transmits to the lower chamber or cylinder through pipes, the amount
of water delivered and steam pressure transmitted to the lower chamber being
regulated by the intermediately placed valve.
The oil would flow from the lower chamber under the steam pressure communi-
cated from the upper chamber were there no water in the latter and the function
of the water in the lower chamber would be merely to float the oil so as to have it
overflow through the delivery pipe; hence the steam pressure upon the upper
chamber is an important factor and the water in the upper chamber, except as a
source of supply through the regulating valve to float the oil, a secondary one so
far as hydrostatic pressure is concerned from above and independently of the steam-
pressure exerted upon it.
By thus constructing the lubricating device so as to take steam from the interior
of the steam-supplied chamber through a pipe with which to force the delivery of
the oil towards the point of its use and thus connecting this chamber with the
lower chamber to utilize this same steam pressure to supply water to, and to force
the overflow of oil from the lower chamber, a single steam connection with the
lubricator is made to perform several important uses within the lubricator in a
manner and by a means of construction that ensures uniformity of pressure within
the lubricator and a regular delivery of oil therefrom.
The two lubricating vessels have a branch connection which connects them with
the boiler and each of them is a duplicate of the other and has a conduit pipe to
connect it separately with one of the steam cylinders. This branch connection to
supply the interior of each lubricator with steam for the purpose hereinbefore
nained and described is also branched to supply an auxiliary steam-pipe connection
with the conduit-pipes of each lubricator, so that a single tube connection operates
both of them.
I will now proceed to describe the second part of my said Invention. The glass
cup or reservoir is formed with a neck and adapted to contain a suitable quantity
of lubricant, as usual. I provide an externally screw-threaded collar which is fitted
upon the neck of the cup and adapted to couple with a nozzle that is designed to
be detachably connected with the threaded collar in order that it may be removed
when it becomes necessary to introduce a fresh supply of lubricant into the cup.
In the present instance the nozzle comprises an externally screw-threaded nipple,

page_text: having at its upper end an internally screw-threaded cap, provided with a suitable
packing ring, the cap being adapted to be screwed up on the collar that is fitted to
the neck of the cup, and the screw threaded nipple being adapted for attachment
to the engines or other mechanism to be lubricated.
In turning either the cup or the nozzle for the purpose of detachment, the glass
neck will turn in the collar that is fitted thereon, or the collar will be turned upon
the said neck unless means other than the mere frictional contact between the
neck and the collar are provided. Also the same difficulty will be experienced in
screwing up the screw-threaded cap of the nozzle since an attempt to rotate the
cap will cause the collar to turn upon the neck. In order therefore to render the
collar rigid upon the glass neck and thereby prevent the cup and the collar from
turning independently of each other, I form the glass cup with a score or groove
which extends around the cup from end to end, and has its terminals in the neck
at, or near, the edge of the same, and in the said score or groove I fit a retaining
wire which is connected at its ends with the ring or collar. This retaining wire
which is thus applied along two sides and across the solid end of the cup, is drawn
down snugly into the groove so as to bind firmly upon the cup and is secured to
the inner face of the ring or collar by solder, rivets, or analogous means.
addition to the grooves in the neck which receive the ends of the wire, the collar
might be correspondingly grooved or notched in its inner face so that a portion of
the wire will also be received in the grooves or notches of the collar, which
arrangement would serve as an auxiliary to the collar or rivets employed.
In
I provide a rod designed to fit loosely within the nozzle and project both below
and above the same, so as to enter the oil-cup and rest upon the journal over which
the cup is placed, in order to automatically cause the flow of oil during the
operation of the machine or engine to which the oil-cup is attached.
It will be evident that it will not be necessary to make the groove continuous
around the glass cup from one side of its neck to the opposite side of the same,
since, for example, the groove could be discontinued at that end of the cup which
is opposite to the one provided with the neck. Again, in lieu of the groove in the
body of the cup, the latter might be formed with two lines of lugs or projections,
between which the wire could be placed and held. Also more than one retaining
wire might be employed, if preferred.

tube G the latter being placed within the pipe P which has constructed on
opposite sides sight openings N6, through which the descending oil may be seen.
The oil pipe O³ terminates in a pendant nozzle having a button upon the pipe also
upon the pendant discharge end. Within the chamber A¹ there is a steam pipe S³
opening into this chamber, so as to receive steam under pressure therefroin. This
steam pipe S³ passes downwardly through the condensing chamber A' into the
cored arm pipe P¹ at S where it connects with the annular chamber a formed in
the said pipe, and from which the steam under pressure is forced through the glass
tube G, being deflected to the sides of the latter by the flat ring on the oil pipe 0³,
above the discharge pendant nozzle end of the latter. From this point the
dropping oil and the steam pass downwardly and around the three-sided stem of
the poppet valve n within the oil conduit pipe O, and from thence into the annular
space S' in the horizontal pipe P, from which it passes into and through the conduit
pipe O, which connects with the steam cylinder.
To protect the glass tubes of the lubricators through which the oil and steam
passes, I surround them with the protecting pipe P2, which has oppositely arranged
sight openings no, no and combine with the latter a clamp constructed with the
stopper plugs n³, no and the screw and thumb piece W so that in case the glass
tube becomes broken the lubricator may be temporarily used without the tube
until the latter is replaced. To prevent any unusual back pressure from the steam
cylinders and the consequent churning up of the oil and water so as to interfere
with the uniform flow and delivery of the oil from the lubricator vessel, I
construct within the oil delivery pipe 04, the poppet valve n, the stem of which is
three sided so as to allow a passage along the stem, and between it and the sides
of the pipe supplying the oil to the conduit pipe leading to the steam cylinder. The
button of the valve n seating to close the pipe O, in the rounded top n7, of the
annular chamber S7, which forms the outlet of the latter pipe, when any unusual
pressure from the cylinder causes the valve to rise and thus close.
When steam is shut off from the steam cylinders of a locomotive as is the case
when the latter is descending an incline, the vacuum tendency produced in the
steam cylinders draws the oil from the lubricating vessels so as to sometimes
empty them. To avoid this difficulty I connect the oil conduit pipe leading to
the steam cylinders, directly with the boiler, by which this tendency is relieved.

page_text: This auxiliary pipe e at its upper end connects with the steam pipe S', and its
lower end e opens into the oil conduit pipe O*; part of the arm P being cored out
to form a continuation of the pipe es. While I have shown this improved feature
of an auxiliary steam pipe connecting the oil conduit pipe that leads to the
cylinder, as applied to a duplicated lubricator each of which two connects
separately with one of the steam cylinders, it may be applied in the same manner
and so as to perform the same useful office to each of the branch cylinder connections
made with a single lubricator.
The condensing chamber A¹ serves to collect water and receive pressure from the
steam boiler by means of the pipe S, and the received pressure and accumulated
condensation it transmits to the lower chamber A³ through the pipes and do, the
amount of water delivered and steam pressure transmitted to the lower chamber A'
being regulated by the intermediately placed valve V¹,
The position of the water in the upper and lower cylinders being indicated at a³,
and that of the oil in the lower chamber at O, it is obvious that the oil would
flow from the lower chamber under the steam pressure communicated from the
chamber A' were there no water in the latter, and the function of the water in the
lower chamber A² would be merely to float the oil so as to have it overflow through
the delivery pipe 02, hence the steam pressure upon the upper chamber is an
important factor, and the water in the upper chamber, except as a source of supply
through the regulating valve to float the oil, a secondary one so far as hydrostatic
pressure is concerned from above and independently of the steam pressure exerted
upon it. By thus constructing the lubricating device, so as to take steam from the
interior of the chamber A¹ through the pipe S³ with which to force the delivery of
the oil towards the point of its use, and thus connecting this chamber A' with the
chamber A' to utilize this same steam pressure to supply water to and to force the
overflow of oil from the chamber A, a single steam connection with the lubricator
is made to perform several important uses within the lubricator, in a manner
and by a means of construction which ensures uniformity of pressure within the
lubricator and a regular delivery of oil therefrom
The two lubricating vessels X and X, X have a branch connection S2 which
connects them at S' with the boiler, and each of them is a duplicate of the other
and has a conduit pipe to connect it separately with one of the steam cylinders.
This branch connection for supplying the interior of each lubricator with steam
for the purpose herein before named and described, is also branched to supply an
auxiliary steam pipe connection with the conduit pipes of each lubricator, so that a
single tube connection made at S' operates both of them
Referring to figures 4 to 9 of the drawing A indicates a glass cup or reservoir
formed with a neck A' and adapted to contain a suitable quantity of lubricant, as
usual. B indicates an externally screw threaded collar which is fitted upon the
neck of the cup and adapted to couple with a nozzle designed to be detachably
connected with the said threaded collar, in order that it may be removed when it
becomes necessary to introduce a fresh supply of lubricant into the cup. In the
present instance the nozzle C comprises an externally screw threaded nipple C¹,
having at its upper end an internally screw threaded cap C³, provided with a
suitable packing ring D, the cap being adapted to be screwed up on the collar that
is fitted to the neck of the cup, and the screw threaded nipple being adapted for
attachment to engines or other mechanism to be lubricated
In turning either the cup or the nozzle for the purpose of detachment, the glass
neck will turn in the collar that is fitted thereon, or the collar will be turned upon
the said neck unless means other than the mere frictional contact between the
neck and the collar are provided. Also the same difficulty will be experienced in
screwing up the screw-threaded cap of the nozzle, since an attempt to rotate the
cap will cause the collar to turn upon the neck. In order therefore to render the
collar rigid upon the glass neck and thereby prevent the cup and the collar from
turning independently of each other, I form the glass cup with a groove E, which
extends around the said cup from end to end, and has its terminals in the neck at

page_text: or near the edge of the same, and into the said groove I fit the retaining wire F
which is connected at its ends with the ring or collar B. This retaining wire,
which is thus applied along two sides and across the solid end of the cup, is
drawn down snugly into the groove so as to bind firmly upon the cup, and is
secured to the inner face of the ring or collar by solder rivets, or analogous means.
In addition to the grooves in the neck which receive the ends of the wire, the
collar might be correspondingly grooved or notched in its inner face, so that a
portion of the said wire will also be received in the grooves or notches of the collar
which arrangement would serve as an auxiliary to the collar or rivets employed.
The rod G illustrated in several of the figures is the same as one heretofore
employed in this class of oil cups and is designed to fit loosely within the nozzle
and project both between and above the same, so as to enter the oil cup and rest
upon the journal over which the cup is placed, in order to automatically cause the
flow of oil during the operation of the machine or engine to which the oil cup is
attached.
It will be evident that it will not be necessary to make the groove continuous
around the glass cup from one side of its neck to the opposite side of the same,
since, for example, the groove could be discontinued at that end of the cup which
is opposite to the one provided with the neck. Again in lieu of the groove in the
body of the cup the latter might be formed with two lines of lugs or projections,
between which the wire could be placed and held. Also more than one retaining
wire may be employed if preferred.
Having thus fully described the said invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
