PROVISIONAL SPECIFICATION left by the said Edward Thomas Hughes
at the Office of the Commissioners of Patents, with his Petition,
on the 22nd September 1871.
I, EDWARD THOMAS HUGHES, of the Firm of Hughes and Son,
Patent Agents, 123, Chancery Lane, London, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN LUBRICATORS FOR STEAM
ENGINES," a communication to me from abroad by James Harper, of the

page_text: City and County of New Haven, State of Connecticut, United States of
America, to be as follows:-
This Invention relates to improvements in that class of steam
lubricators in which the lubricating material is transferred from the
lubricator by the action of the steam to the point where lubrication is
desired, and consists in the arrangement of a chamber for the lubri-
cating material, having an outside passage communicating with the
said chamber at the top and bottom, and a valve connected with the
said chamber through which the steam passes, so that the condensation
of the steam occurring at or near the valve passes freely into the said
chamber, causing the lubricating material to rise proportionately into
the said valve, or where it may communicate directly with the steam,
and there mingling with the steam' be carried by the flowing steam to
the valves or whatever it may come in contact with, as more fully
herein-after described.
In the accompanying Sheet of Drawings Fig. 1 represents a side
view, Fig. 2 a similar view of the upper portion turned one-fourth
around to the left, and Fig. 3 a vertical central section in position of
Fig. 1.
A is the lubricating material chamber, this and the other parts being
proportioned to the size of the apparatus to which this device is to be
applied; B is the upper and C the lower head; D is a tube of glass or
other suitable material, and is arranged so as to open into the top and
bottom of the chamber A by passages E, F; therefore the position or
quantity of fluid in the chamber will always be indicated in the
tube D. Above the highest part of the chamber A I arrange a filling
cup G, here represented as a continuation of the tube D; and below
this filling cup G and in the leading tube I arrange a cock H or other
suitable cut off, by which the communication from the cup G to the
chamber may be cut off above the chamber. At a convenient point
below the chamber I arrange another cock I by means of which the
contents of the chamber may be drawn off. At some convenient point
above and in connection with the chamber I arrange a valve L, which
when in the position seen in Fig. 3 allows the free passage of the steam
therethrough. The spindle I of the valve is for convenience perforated
longitudinally to allow the escape of air from the chamber when being
filled. This perforation is opened and closed by a cap P or other
suitable device.

This apparatus should be arranged so that the valve or steam
passage L be above the highest valve or point to be lubricated; arranged
in such position, run the spindle I down to close the passage T between
the steam passage L and chamber A; open or remove the cap P, open'
the cock or passage H, and pour in the lubricating material until the
chamber is perfectly filled and no air remains, and this will be when no
more oil or material will pass from the cup, then close the cock H and
cap P; now open the passage T by slightly raising the spindle I; the
condensation of the steam at or near the passage or valve I will drip
into the chamber A through the passage T, and being heavier than the
lubricating material will sink to the bottom of the chamber A, causing
the lubricating material to rise proportionately into the steam passage,
where it mingles with the steam and is taken with the steam to the
valves or whatever it is desired to lubricate or oil by contact with the
steam. The quantity of oil or lubricating material thus supplied
depends upon the extent to which the passage T is opened or the
amount of condensed steam which enters the chamber through the said
passage.
i
'
The water from condensation which falls to the bottom of the
chamber also flows into the tube D, and maintaining the same level in
both indicates at all times in the tube the amount of lubricating
material in the chamber, and consequently the rapidity with which
the material is being consumed. The consumption is regulated by
opening or closing the passage T as more or less is required..... To
replenish the chamber close the passage T, open the cock H and cap P
and cock R, and through the latter the water will pass out, and when
all out close the cock R and fill the chamber as before described.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Thomas Hughes in the Great Seal Patent
Office on the 22nd March 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
THOMAS HUGHES, of the Firm of Hughes and Son, Patent Agents,
123, Chancery Lane, London, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of September, in the.

page_text: year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Edward Thomas Hughes, Her
special licence that I, the said Edward Thomas Hughes, my executors,
administrators, and assigns, or such others as I, the said Edward Thomas
Hughes, 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 "IMPROVEMENTS IN LUBRICATORS FOR STEAM Engines,” a communication
to me from abroad by James Harper, of the City and County of New
Haven, State of Connecticut, United States of America, upon the
condition (amongst others) that I, the said Edward Thomas Hughes;
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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Edward Thomas Hughes, 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 accom-
panying Sheet of Drawings, that is to say :-
This Invention relates to improvements in that class of steam
lubricators in which the lubricating material is transferred from the
lubricator by the action of the steam to the point where lubrication
is desired, and consists in the arrangement of a chamber for the
lubricating material, having an outside passage communicating with
the said chamber at the top and bottom, and a valve connected with
the said chamber through which the steam passes, so that the conden-
sation of the steam occurring at or near the valve passes freely into
the said chamber, causing the lubricating material to rise proportionately
into the said valve, or where it may communicate directly with the
steam, and there mingling with the steam be carried by the flowing
steam to the valves or whatever it may come in contact with, as
more fully herein-after described.

page_text: In the accompanying Sheet of Drawings Fig. 1 represents a side
view, Fig. 2 a similar view of the upper portion turned one-fourth
around to the left, and Fig. 3 a vertical central section in position of
Fig. 1.
A is the lubricating material chamber, this and the other parts being
proportioned to the size of. the apparatus to which this device is to be
applied; B is the upper and C the lower head; D is a tube of glass or
other suitable material, and is arranged so as to open into the top and
bottom of the chamber A by passages E, F; therefore the position or
quantity of fluid in the chamber will always be indicated in the tube D.
Above the highest part of the chamber A I arrange a filling cup G,
here represented as a continuation of the tube D, and below this filling
cup G and in the leading tube I arrange a cock H or other suitable
cut off by which the communication from the cup G to the chamber
may be cut off above the chamber. At a convenient point below the
chamber I arrange another cock I, by means of which the contents of
the chamber may be drawn off. At some convenient point above and
in connection with the chamber I arrange a valve L, which when in
the position seen in Fig. 3 allows the free passage of the steam there-
through. The spindle I of the valve is for convenience perforated
longitudinally to allow the escape of air from the chamber when
being filled. This perforation is opened and closed by a cap P or other
suitable device.
This apparatus should be arranged so that the valve or steam
passage L be above the highest valve or point to be lubricated ;
arranged in such position run the spindle I down to close the passage T
between the steam passage L and chamber A, open or remove the
cap P, open the cock or passage H and pour in the lubricating material
until the chamber is perfectly filled and no air remains, and this will
be when no more oil or material will pass from the cup, then close the
cock H and cap P; now open the passage T´by slightly raising the
spindle I, the condensation of the steam at or near the passage or valve
I will drip into the chamber A through the passage T, and being.
heavier than the lubricating material will sink to the bottom of the
chamber A, causing the lubricating material to rise proportionately
into the steam passage, where it mingles with the steam and is taken
with the steam to the valves or whatever it is desired to lubricate or
oil by contact with the steam. The quantity of oil or lubricating

described for this modification.
This result is attained in my lubricator as first described by plugging
up one of the openings in the valve to prevent the circulation. This
done the lubricator may be applied in the same manner as I have
described for this modification.
A vent cock should be inserted at some point in the valve L to allow
the air therein to escape.
I do not wish to be understood as confining myself to the precise
construction of the parts as described, it only being requisite that
substantially the relative position specified be maintained.
I claim as the Invention communicated to me,-
First. The chamber A provided with a means for filling combined
with the steam passage L and passage T, the said passage T provided
with a valve to open or close the said passage, substantially as and for
the purpose specified.
Secondly. In combination with the subject matter of the first clause
of claim I claim the indicating tube D as and for the purpose described.
And, thirdly. In combination with the chamber A and passage T with
its valve, I claim the chamber L connecting with the said chamber A,
and provided with a single opening P to allow the steam to enter and
return by the same passage, substantially as set forth.
In witness whereof, I, the said Edward Thomas Hughes, have
hereunto set my hand and seal, this Twenty-second day of
March, in the year of our Lord One thousand eight hundred and
seventy-two.
