page_text: LETTERS PATENT to William Burnett, of San Francisco, California,
United States of America, now of No. 8, Southampton Buildings,
London, for the Invention of "AN IMPROVED METHOD OF AND APPA-
Sealed the 24th June 1873, and dated the 24th April 1873.
PROVISIONAL SPECIFICATION left by the said William Burnett at the
Office of the Commissioners of Patents, with his Petition, on the
24th April 1873.
I, WILLIAM BURNETT, of San Francisco, California, United States of
America, now of No. 8, Southampton Buildings, London, do hereby
declare the nature of the said Invention for "AN IMPROVED METHOD OF
AND APPARATUS FOR SUPPLYING OIL FOR LUBRICATION," to be as follows :—
My Invention relates to a novel method of lubrication, and to appa-
ratus for carrying the same into effect, whereby oil is supplied from
a reservoir through water contained in a glass or other transparent
vessel, wherein the delivery or transmission can be at all times observed,

page_text: and therefore the supply of oil can be regulated as may be desirable or
necessary.
To carry my said Invention into effect I prefer to use an apparatus
which has the said glass vessel or water chamber placed over the oil
reservoir. The latter is preferably a cylindrical vessel of brass or other
suitable metal of any desired capacity, and provided at each end with a
cap or cover made fast on it by screwing or otherwise. The cover at the
lower end is provided with a waste cock or valve. The upper cap or
cover is made in the form of a dish or basin, and is supported upon a
bracket or table through which the oil cylinder depends. This dish or
basin serves for filling the oil reservoir, and also for the reception of the
drip or leakage from the cocks or valves above it. The said dish is
provided with a cock for drawing off its contents. In the centre of this
dish or basin I secure a vertical stand which supports the aforesaid
water chamber or vessel. This vessel is preferably a tube or cylinder of
glass; it is made of any required size or capacity, its upper end being
closed by a metal cap provided with a filling plug. The said tube is
made tight at both ends by india-rubber or other suitable packing, and
is firmly secured upon the stand of the oil reservoir by bolts which are
screwed into the said stand, and extend through the cap of the said glass
vessel above which they are provided with screw nuts.
The said oil reservoir and water chamber communicate directly with
cach other by a small central opening through the aforesaid vertical.
stand. The said dish or basin is also provided with a screw plug or a
cock or a valve, whereby the oil reservoir is filled.
.
Inside the water chamber I place a small tube which is made fast in
the said stand, and extends nearly to the top of the said water chamber.
Through the side of the stand I form a passage which communicates
with this tube, and which is controlled by a cock or valve at the side of
the stand. This valve or cock is connected to a pipe or tube leading to
the parts to be lubricated. The said stand also has a cock or valve con-
nected with a passage extending down into the oil reservoir, and also
connected with a pipe supplied with water under either elastic or hydro-
static pressure. The said central stand is also fitted with a waste cock
or valve for drawing off the contents of the water chamber, and with a
cock or valve for permitting the entrance of air into the oil reservoir, or
permitting its escape therefrom when the said reservoir is being filled or
emptied.

page_text: The oil reservoir having been filled through the plug opening in the
dish or basin the plug is replaced, the water chamber is, then filled, or
nearly filled, with water, and the delivery cock or valve opened; then
if the induction cock or valve is slightly opened water will enter the
oil reservoir, and will sink through the oil to the bottom of the chamber,
the oil displaced being forced into the glass chamber, ascending in drops
or globules through the water contained therein to the top of the said
chamber, from which it passes away through the delivery cock and pipe.
Each drop of oil withdrawn from the top of the water chamber is replaced
by a drop or globule of oil ascending as above described from the oil
reservoir.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Burnett in the Great. Seal Patent Office on
the 21st October 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BURNETT, of San Francisco, California, United States of America, now
of No. 8, Southampton Buildings, London, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of April, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-.
sixth year of Her reign, did, for Herself,- Her heirs and successors, give
and grant unto me, the said William Burnett, Her special licence that I,
the said William Burnett, my executors, administrators, and assigns, or
such others as I, the said William Burnett, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the.
United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "AN IMPROVED METHOD OF AND APPARATUS.
FOR SUPPLYING OIL FOR LUBRICATION," upon the condition (amongst others)
that I, the said William Burnett, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and.
scals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six.

section of the upper part of the same; Figure 3 is a horizontal section on
the line x, x, Figure 1. Like letters indicate the same parts throughout a
the Drawing.
a is the water chamber, and 6 is the oil reservoir.
It will be seen that this apparatus has the said glass vessel or water
chamber a placed over the oil reservoir b, but it may be otherwise
arranged if desired. The said oil vessel is preferably a cylinder of brass
or other suitable metal of any desired capacity, and is provided at each
end with a cap or cover made fast on it by screwing or otherwise. The
cover c at the lower end is provided with a waste cock or valve c¹. The
upper cap or cover d is made in the form of a dish or basin, as shewn in
Figure 2, and is supported upon a bracket e, through which the oil
cylinder extends downward. This dish or basin serves as a funnel for
filling the oil reservoir 6, and also for the reception of the drip or
leakage from the cocks or valves above it.
The said dish is provided
with a cock d for drawing off its contents. In the centre of this dish or
basin I secure a vertical stand or pillar which supports the aforesaid

page_text: water chamber or vessel a. This vessel is preferably a tube or cylinder.
of glass, made of any required size or capacity, its upper end being closed
by a metal cap provided with a filling plug g¹. It is made tight at
both ends by india-rubber discs h or other suitable packing, and it is
firmly secured upon the stand f of the oil reservoir 6 by bolts i which
are screwed into the stand f, and extend through the cap g of the said
glass vessel, above which they are provided with screw nuts 2, as
shewn.
The oil reservoir 6 and water chamber a communicate directly with:
cach other by a small central passage j through the aforesaid vertical
stand f. The dish or basin d is provided with a screw plug d², or with.
a cock or valve, whereby the oil reservoir is filled.
"
The said stand'
extending down
Inside the water chamber a is a small tube k which is made fast in
the stand, and extends nearly to the top of the said water chamber, ns‍
shewn in Figure 2. Through the side of the stand f I form a passage k¹
which communicates with the tube %, and is controlled by a cock or
valve at the side of the stand. This valve or cock is connected to a
pipe or tube extending to the parts to be lubricated.
also has a cock or valve connected with a passage
into the oil reservoir b, and the said cock or valve is also connected with a
pipe supplied with water under either elastic or hydrostatic pressure. The
said central stand is also fitted with a waste cock or valve m for drawing
off the contents of the water chamber, and with a cock or valve n for
permitting the entrance of air into the oil reservoir b, or permitting its
escape therefrom when the said reservoir is being emptied or filled.
The oil reservoir & having been filled through the plug opening in the
dish or basin d, the said opening is closed by the plug d². The water
chamber a is then filled, or nearly filled with water, and the delivery
cock or valve k is opened; then, if the induction cock or valve / is
partially opened, water will enter the oil reservoir band will sink through
the oil therein to the bottom of the said reservoir. The oil displaced is
forced into the glass chamber a, ascending in drops or globules through
the water therein to the top of the said chamber, from which it passes
away through the delivery cock and pipe. Each drop of oil withdrawn
from the top of the water chamber a is replaced by a drop or globule of
oil ascending, as above described, from the reservoir b, and this action
being plainly visible through the transparent sides of the water chamber

page_text: the rate of feed or delivery may be determined at all times, and the
quantity of oil transmitted regulated with the greatest exactitude.
Having thus fully described my said Invention, and the manner of
performing the same, I wish it understood that I do not confine myself
to the precise arrangement of parts shewn in the Drawing, as any other 5
arrangement which will serve to carry into effect the method herein
described of supplying oil for lubrication by causing the same to ascend
through water contained in a transparent vessel may be adopted, and I
claim,―
First. In a lubricating apparatus transmitting the oil to the parts to 1
be lubricated through water or other suitable liquid in a transparent
chamber, for the purpose specified.
Second. In combination with the oil and water chambers of the said
lubricating apparatus the dish or basin, arranged as herein set forth for
the purposes specified.
Third. The vertical pipe arranged within the water chamber, and
connected with the delivery passage and cock, as herein described for
the purposes specified.
Fourth. A lubricating apparatus consisting of the oil and water
chambers and other parts, constructed and combined substantially as
herein described and as shewn in the accompanying Drawing.
In witness whereof, I, the said William Burnett, have hereunto set
my hand and seal, this Eighteenth day of October, in the year of
"our Lord One thousand eight hundred and seventy-three.
