Year: 1885

page_text: I JOHN THOMAS HAILWOOD of No 186 Ramsey Street Rochdale in the County
of Lancaster Commission Agent do hereby declare the nature of my said invention
for "AN IMPROVED SIGHT FEED LUBRICATOR" to be as follows:-
My Invention relates to improvements in lubricators known as sight feed.
lubricators and has for its object the lubrication of steam engine cylinders or other.
parts I employ an ordinary lubricator cup its lower part being preferably hollow
upwards through which passes in a vertical direction a tube or pipe for the
admission of steam or if desirable may be fixed on the exterior of the cup which
tube or pipe is attached to the steam pipe communicating between the boiler and
the cylinder of the engine at the upper extremity of the tube I provide a convenient
pipe its position being horizontal to the vertical tube the one extremity of the
latter being of curved or syphon form extending downwards into the oil cup and
terminating at or near its lower part its other extremity terminating suitably into
and being connected with a glass tube termed the sight tube the lower part of the
glass tube being in connection with a three way branched tube affording free
passages from the glass tube and the oil cup terminating into the tube or lower
part of the oil cup which forms the passage for the lubricant extending to the part
to be lubricated the passages in the three branched pipe being opened and closed
by operating a suitable tap or cock the upper part of the cup being conveniently
provided with a suitable tube or opening terminating in the glass tube which is for
the passage of the oil its extremity being at or near the tube admitting steam into
the sight tube the upper part of the vertical tube is provided with a valve, at the
connection with the horizontal tube which valve opens and, closes the passages or
thoroughfare in the horizontal tube the steam is thus admitted to the cup and the
sight tube the operation of the lubricator is as follows-When steam is admitted
into the vertical tube the valve is caused to open by the action of the steam which
passes into the cup.and the glass tube the steam condensing in the oil cup thus
elevates the lubricant contained therein and forces the same through the aperture
or tube at its upper part through a nozzle thence into the glass tube the lubricant
being in contact with the steam is forced thereby and when the three way cock is
suitably opened into the lower part of the oil cup thus to the part to be lubricated
the flow of oil being regulated as required by operating a suitable tap when the

page_text: oil is discharged from the cup the thoroughfare in the three branch pipe is opened
the water being admitted into the tube or lower part of the cup thus providing for
an escape of water when not in use if desirable I employ a coil of any suitable
material through which the steam is caused to pass and for the purpose of the
more effectually condensing the steam which is effected by conveniently connecting
the one extremity of the coil to the steam tube its other extremity terminating at
or near the bottom of the oil cup.
I JOHN THOMAS HAILWOOD of no. 186, Ramsey Street Rochdale in the County
of Lancaster commission agent, do hereby declare the nature of my invention for
AN IMPROVED SIGHT FEED LUBRICATOR and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
My invention relates to improvements is sight-feed lubricators which are used
for the purpose of lubricating steam-engine cylinders or other parts of machinery.
In order that my invention may be understood, I refer to the accompaning
sheet of drawings in which like letters of reference throughout the drawings
indicate like parts.
Fig. 1 represents a sectional elevation of my invention.
Fig. 2 is a sectional elevation shewing another method of carrying my invention
into effect.
Fig. 3 is a sectional elevation of another arrangement with condenser.
Fig. 4 is a front elevation of Fig. 3.
Fig. 5 is a plan thereof.
Fig. 6 is a view shewing another mode by which lubricating matter may be
passed in the sight-tube to the parts to be lubricated. I employ an ordinary
lubricator cup A Fig. 1 its lower parts being preferably hollow upwards through
which at any convenient part passes a steam or inlet tube B being connected at its
one extremity conveniently to a steam pipe or passage terminating in a suitable
chamber C. arranged conveniently above a glass sight-tube D. a passage or communi-
cation E. being provided hereinafter to be referred to at the upper part of the
cup A. is a passage or thoroughfare F. its other extremity terminating in the
chamber C. at any convenient part of the pipe or tube B. I fix a branch or
connection G provided with a valve H when steam is admitted in the steam pipe
or tube B. consequently steam is admitted into the oil cup A through the valve H
v

page_text: and 18 caused to condense therein at the upper part of the cup is an opening I
through which oil or water may be passed into the cup as may be desired steam
also is admitted into the chamber C at the other extremity of the pipe or tube B
as the steam is caused to condense in the oil cup the oil as shewn in black in the
drawings is elevated to the upper part of the cup and forced through the passage F
into the chamber C being regulated at its outlet in such chamber by a suitable
valve J the accumalated steam in the chamber is caused to surround; the delivery
tube or opening F the same extending more or less in the chamber G. as may be
desired thus the lubricant which may be of a heavy bodied nature is maintained or
kept in a liquid state at that part the lubricant being admitted into the chamber
by operating the valve J is thence forced by the steam from the tube B. through
the passage E through the nozzle K into the glass tube D as shewn in Fig. 1 thence
into the passage or thoroughfares L into the delivery or lubricating tube M. which
is connected to the steam cylinder or 'other part of the machinery desired to be
lubricated or if necessary I may vary the demensions and form of the passage AI
see Fig. 6 for the purpose of forcing the lubricant through the sight tube in small
jets or particles and so arrange the steam passage C around the oil passage A' as
required for the purpose of maintaining the lubricant in a liquid state thus to
facilitate the discharge in the sight-tube at the lower part of the cup is a passage
or thoroughfare N which is for the purpose of drawing off water from the cup
when the oil is discharged therefrom at any suitable part is fixed a suitable three-
way cock or other suitable valve which controls the thoroughfares L. M and N
accordingly as it is desired to admit the lubricant into the delivery tube M or as it
is desired to admit the condensed water through the passage N obviously the
water is drawn off or discharged from the cup through the lubricating tube thus
obviating any waste of lubricating matter as is the case with many lubricators
now in use and which I claim to be the chief feature of my invention.
Fig. 2 shews another arrangement of carrying out my invention the steam or
inlet tube B passes vertically into the cup being provided at its upper part with
a horizontal tube O, its extremities terminating at or near the lower part of the
cup A and into a chamber C respectively at the upper part of the cup is a
thoroughfare P which is for the admittance of the lubricant into the chamber C
steam being admitted in steam pipe B by operating a suitable valve as is well
understood passes into the cup and the chamber C. at the extremities of the tube O
the steam condensing in the cup as before stated elevates the oil forcing the same
through the passage P into the chamber C. its flow being regulated by suitably
operating the valve J the oil being forced through the passage E. through the
nozzle K into the sight-tube D. thence through the passage or thoroughfare L
which thoroughfare terminates at or near the part or parts of the machine to be
lubricated at the lower part of the cup is a thoroughfare N through which the
water is discharged into the thoroughfare or lubricating tube L by suitably
operating the threeway cock R.
My arrangement as shewn in Fig. 3 consists in the application of. a spiral coil S
of copper or other suitable material which coil acts as a condenser the steam passes
upwards in the tube B, into the coil at its upper part terminating at the extremity
of the tube B into the oil cup the condensed steam elevating the lubricant in the
cup and forcing the same down the tube. or thoroughfare T see Figs. 3 & 5
terminating at the nozzle U. in the sight tube D. thence through the passage UI.
into the steam pipe B. the flow of oil being regulated by a suitable valve or cock Y
which also admits steam into the coil S. from the steam pipe B. I provide a cover
or shield W. which may contain water for the purpose of cooling the coil S during
the passage of steam from the same into the oil cup thus the better effecting
condensation of the steam in the coil at the lower part of the cup is a thorough-
fare N. for the purpose of discharging water from the cup into the steam pipe
when the oil is discharged from the cup the opening and closing of the thoroughfare
being effected by operating a suitable valve V.
