AN IMPROVED SIGHT FEED LUBRICATOR
Year: 1884

page_text: I ROBERT MONTGOMERY 9 Stanners Street Greenock in the County of
Renfreshire Brassfounder do hereby declare the nature of my invention for
AN IMPROVED SIGHT FEED LUBRICATOR to be as follows:-
This Lubricator is for the Lubrication of Steam Engine Cylinders, Casings or
steam pipes The Glass on side of cup is packed by a new arrangement by the top
side The Oil passes up through the glass then gos down through center of cup.
doing away with pipes now generaly used in this class of Lubricator it can be
fixed direct on Cylinder &c as well as on starting platform There is a drain
cock or valve on side of cup so that when the cup is being drained it is shut
to condensed water pipe by the simplicity of this Lubricator it can be made
cheaply.
With refrence to drawing
The Oil is contained in a cylindrical vessell A with gauge glass brackets on side
The gauge bracket C has a recess turned out to receive I. R. washer O & the top
bracket B has a metal washer F which carries I. R. washer O the plug 9 on top has
a projection on center which coms down & presses washer F with I. R. washer
thereon & makes a tight joint on end of glass The cock L on the side of cup is
for draining out water from cup when it is to be refilled with Oil & prevents the
condensed water in tube from being drained The top valve P is for filling the cup
The bottom valve H which carries the cup is screwed on bottom so that it can be
fixed direct on casing steam pipe &c or if its to be fixed on starting platform the
plug S is replaced with coupling to fix pipe to be carried to casing steam pipe &c
There is a ferrel T screwed into bottom of cup A which secures tube coming from
gauge bracket B There is also a tube M screwed into bottom bracket C which runs
to near top of cup.
The action is as follows
The cup is filled with water by valve P untill it rises to top Glass then drain the
cup by cock L but the water will remain in glass Shut the cock L & fill with Oil
Shut valve P & open cock L to condensed water tube & by opening the valve R
by the head of water in pipe it will force the Oil down the tube M untill it reaches
to nozel of lower gauge bracket C then it floats, up through the water in glass
tube then.gos down tube N through center of cup to casing steam pipe &c.

I ROBERT MONTGOMERY 9 Stanners Street Greenock in the County of
Renfreshire Brassfounder 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:
With refrence to Drawings the Oil is contained in a cylindrical vessell A with
glass brackets mounted on side the bottom gauge bracket C has a recess turned out
to receive India Rubber washer & the top bracket B has a metal washer F which
also carries I. R. washer The plug g on top of B has a projection on center which
comes down & presses washers F with I. R. washer on end of glass thus makes a
tight joint of glass tube The cock L on side of cup is for draining water from cup
when it is to be refilled with oil & prevents the water from being drained from
condensed water tube ; The top valve P is for filling the cup. The bottom
valve H which carries the cup is screwed on bottom so as to go into casing steam
pipe or if on starting platform the plug S is replaced with coupling to fix pipe
runing to casing or steam pipe. There is a ferrel T screwed into bottom of cup A
which secures tube comming from gauge bracket B ther is another tube screwed
into bottom bracket which runs to near the top of cup A there is a valve R on
bottom piece for regulating the supply of Oil
The action of the cup is as follows
The cup being fixed on Steam pipe or casing of the engine & the condensed
water pipe the one end is fixed on steam pipe & carried up above the cup (or casing
in cases when the cup is fixed on starting platform) thus to secure a head of water
The cup
is filled with water through the valve P untill it reaches to the top of
glass Then the cup is drained by the cock L but the water remains in glass then
fill the cup with oil shut the valve P & open cock L to condensed water pipe j & by
opening valve R the head of water will force the oil down through tube N untill it
reaches the bottom of glass in C then it will float up through the water in glass
in drops according to ammount of opening in valve R then it passes down through
tube M in center of cup to the steam pipe casing &c.
Having now particularly described and acertained the nature of said invention
and in what manner the same is to be performed I declare that what I claim is
1st The peculiar construction and arrangement for actuating the same sub-
stantially as and for the purpose hereinbefore described.
2nd The Combination of the pipes inside to simplify the construction of same as
described and illustrated by the accompany Drawings.
3rd The gauge glass of a Lubricator packed as herebefore described.
4th The general arrangement and combination of parts constituting a Lubricator
substantially as hereinbefore described and illustrated by the accompany Drawings.
Dated this 31st March 1885.
