Year: 1871

page_text: LETTERS PATENT to Alfred Vincent Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Mechanical
Draughtsman, for the Invention of "AN IMPROVED CONSTRUCTION OF
LUBRICATOR." A communication from abroad by Nicholas Seibert,
of San Francisco California Tinited States of Amenian
PROVISIONAL SPECIFICATION left by the said Alfred Vincent Newton
at the Office of the Commissioners of Patents, with his Petition,
on the 23rd March 1871.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Mechanical Draughtsman, do hereby
declare the nature of the said Invention for "AN IMPROVED CONSTRUCTION
OF LUBRICATOR," to be as follows:-
This Invention relates to an improved construction of lubricator for
supplying oil and other lubricant to steam engines and other machinery.
The reservoir for containing the oil may consist of a vertical cylinder
closed at top by a screw plug which is withdrawn in order to renew the

page_text: supply. This cylinder is connected at top and bottom by lateral pipes
with a glass tube, that stands parallel to the cylinder and serves to
indicate the amount of lubricant in the cylinder. A sliding gauge is
applied to the glass tube to indicate the amount of oil consumed. By
the side of the oil reservoir stands a water reservoir of superior elevation,
and these two reservoirs are connected at bottom by a pipe fitted with
a regulating valve which determines the rate of escape of the water from
the reservoir.
Supposing the lubricator to be applied to a steam engine it will be
conveniently mounted on the steam chest, and in this case the water
reservoir will be connected at top with the steam pipe, which pipe will
also be in connection through a lubricant pipe with the upper end of
the oil reservoir. The pipe forming this latter connection will be fitted
with a stop valve for determining the rate of discharge of the oil.
The action of the apparatus will be as follows:-The water as it leaves
its reservoir will pass to the oil reservoir and accumulating there beneath
the oil will press it upwards and cause it to discharge through the
lubricant pipe into the steam pipe. The oil will then pass with the
steam into the steam engine and lubricate the valves and cylinder. A
corresponding accumulation of water will take place in the glass tube,
the oil rising in proportion as in the oil reservoir and indicating clearly
the action in that vessel.
In order that solid lubricants may be used in this apparatus a central
steam chamber is formed in the oil reservoir and a steam pipe leading
from the steam chest supplies steam thereto for the purpose of melting
the lubricant and retaining it in a fluid state.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred Vincent Newton in the Great Scal Patent
Office on the 21st September 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED 30
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of March, in the year.

page_text: of our Lord One thousand eight hundred and seventy-one, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Alfred Vincent Newton, Her special
licence that I, the said Alfred Vincent Newton, my executors, admi-
nistrators, and assigns, or such others as I, the said Alfred Vincent
Newton, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 CONSTRUCTION OF LUBRICATOR," being a communication
to me from abroad by Nicholas Seibert, of San Francisco, California,
United States of America, upon the condition (amongst others) that
I, the said Alfred Vincent Newton, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands and
seals, 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
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Alfred Vincent Newton, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the Drawing here-
unto annexed, and to the letters and figures marked thereon (that is
to say) :-
This Invention relates to an improved construction of lubricator for
supplying oil and other lubricant to steam engines and other machinery.
The reservoir for containing the oil may consist of a vertical cylinder
closed at top by a screw plug which is withdrawn in order to renew
the supply. This cylinder is connected at top and bottom by lateral.
pipes with a glass tube that stands parallel to the cylinder, and serves to
indicate the amount of lubricant in the cylinder. A sliding gauge is
applied to the glass tube to indicate the amount of oil consumed. By
the side of the oil reservoir stands a water reservoir of superior elevation,
and these two reservoirs are connected at bottom by a pipe fitted with
a regulating valve which determines the rate of escape of the water
from its reservoir.

page_text: Supposing the lubricator to be applied to a steam engine it will be
conveniently mounted on the steam chest, and in this case the water
reservoir will be connected at top with the steam pipe, which pipe will
also be in connection through a lubricant pipe with the upper end of
the oil reservoir. The pipe forming this latter connection will be fitted
with a stop valve for determining the rate of discharge of the oil.
In the accompanying Drawing Fig. 1 represents the improved lubri-
cator in side elevation connected with a steam engine; Fig. 2 is a
vertical central section of the lubricator drawn on an enlarged scale;
and Fig. 3 is a vertical section of the oil reservoir taken at right angles
to Fig. 2. Similar letters of reference indicate corresponding parts in
all the Figures.
A is the steam cylinder and B is the steam pipe connected with the
steam chest C of the engine; D is a water reservoir supplied with water
by the condensed steam pipe D₁, and connected at its lower end with
the bottom of the oil reservoir F; E is the oil pipe connecting the
steam pipe B with the oil reservoir F; G is a stop-cock in the pipe E;
L is the feed valve for regulating the supply of water to the oil reservoir.
Connected with the oil reservoir at top and bottom by passages I, I, is a
glass tube J, and K is a sliding gauge on the glass tube to indicate the
height of the oil in the reservoir; H, Fig. 3, is a check valve past
which the oil flows as it leaves the reservoir to be discharged by the
pipe E into the steam pipe B; F¹ is a cock for emptying the reservoir F,
and F2 is a screw plug at the top of the reservoir closing the supply
opening for the lubricant.
The action of the apparatus will be as follows:-The water as it leaves
the reservoir D regulated in its flow by the valve L will pass to the
oil reservoir F, and accumulating there beneath the oil will press it
upwards and cause it to discharge through the lubricant pipe E into
the steam pipe B. The oil will then pass with the steam into the steam
engine and lubricate the valves and cylinder. A corresponding accumu-
lation of water will take place in the glass tube J, the oil rising in
proportion as in the oil reservoir and indicating clearly the action in
that vessel.
In order that solid lubricants may be used in this apparatus a central
steam chamber is formed in the oil reservoir, and a steam pipe leading
from the steam chest supplies steam thereto for the purpose of melting
the lubricant and retaining it in a fluid state.

page_text: This arrangement is also shewn at Figures 2 and 3 where M is a tube
set up in the centre of the reservoir and closed at its upper end, but
provided with lateral openings at its lower end which connect it with
the reservoir; N is a tube which communicates with the steam in the
steam chest, and is intended to discharge steam into the tube M which
thus forms a heater for the solid lubricant surrounding it; O is a valve
for regulating the supply of steam to the heater.
Having now set forth the nature of the Invention of "An Im-
proved Construction of Lubricator," as communicated to me by my
foreign correspondent, and explained the manner of carrying the same
into effect, I wish it to be understood that under the above in part
recited Letters Patent I claim, the apparatus constructed and operating
as above described for supplying a regulated quantity of lubricant to
steam engines and other machinery.
In witness whereof, I, the said Alfred Vincent Newton, have here-
unto set my hand and seal, the Twentieth day of September, in
the year of our Lord One thousand eight hundred and seventy-
one.
