IMPROVEMENTS IN LUBRICATING APPARATUS
Year: 1862

page_text: LETTERS PATENT to George Henry Birkbeck, of the Firm of Tongue
& Birkbeck, of 84, Southampton Buildings, Chancery Lane, in the
County of Middlesex, Patent Agents & Engineers, for the Invention
of "IMPROVEMENTS IN LUBRICATING APPARATUS."-A communication from
abroad by M. Leon Amenc, Oil Manufacturer, of Paris, in the Empire,
of France.
Sealed the 10th October 1862, and dated the 23rd April 1862.
PROVISIONAL SPECIFICATION left by the said George Henry Birkbeck,
at the Office of the Commissioners of Patents, with his Petition, on
the 23rd April 1862.
Í, GEORGE HENRY BIRKBECK, of the Firm of Tongue & Birkbeck, of
34, Southampton Buildings, Chancery Lane, in the County of Middlesex,
Patent Agents & Engineers do hereby declare the nature of the Invention for
"IMPROVEMENTS IN LUBRICATING APPARATUS," to be as follows:-
This Invention has for its object improvements in apparatus for lubricating
or supplying oil to axles, journals, or other moving parts of machinery, and
consists in so arranging apparatus that a sufficient quantity of oil is constantly
supplied to lubricate the parts required whilst they are in motion, the supply
of oil ceasing whilst they are at rest. The apparatus is also so arranged that

page_text: any excess of oil raised thereby at once flows back into the oil vessel without
being deteriorated by coming in contact with the moving frictional surfaces.
For this purpose an oil vessel or reservoir is supported in any convenient
manner near to the axle, journal, or other moving part of a machine which
requires lubrication. Within this vessel a force pump or other suitable
apparatus capable of raising the oil from one level to another, is arranged so
as to raise a small quantity of the oil from time to time, and deliver it on
to an incline or into a trough along which it flows, and in its passage the oil
flows over an opening or orifice, the extent of which is capable of regulation
by means of an adjustable pin or plug in order to regulate the quantity of
oil which is required to pass through it. This orifice conducts the oil into a
tube or passage leading to the axle, journal, or other part of the machine
requiring lubrication. The excess of oil passing over the incline or trough
falls back again into the main chamber of the oil vessel ready to be again
raised by the force pump or other lifting apparatus; a suitable valve being
arranged between the pump cylinder and the oil chamber, when a pump and
piston are employed.
Motion is communicated to the force pump or other apparatus for lifting
or raising the oil from one compartment of the oil vessel (and delivering it
on to, the incline or trough from which the excess returns into the oil vessel)
by means of a cam or projection on the axle or other moving part of the
machine. This cam or projection in its rotation or movement acts from time
to time upon a lever arm fixed upon an axis exterior of the oil vessel. This
axis passes through and is supported in suitable bearings upon the oil vessel,
or by other convenient means. An arm on the axis interior of the oil vessel is
connected by a pin joint to the piston rod of the pump to give motion thereto.
Or an endless chain or other mechanical means may be employed for lifting
or raising the oil within the oil vessel to lubricate the moving parts as before
described.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Henry Birkbeck, in the Great Seal Patent Office, on
the 14th October 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HENRY BIRKBECK, of the Firm of Tongue and Birkbeck, of 34, Southampton
Buildings, Chancery Lane, in the County of Middlesex, Patent Agents and s
Engineers, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of April, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
George Henry Birkbeck, Her special licence, that I, the said George Henry
Birkbeck, my executors, administrators, and assigns, or such others as I, the
said George Henry Birkbeck, 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 "IMPROVEMENTS IN
LUBRICATING APPARATUS," a communication to me from abroad by M. Leon
Amenc, Oil Manufacturer, of Paris, in the Empire of France, upon the
condition (amongst others) that I, the said George Henry Birkbeck, 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 per-
formed, 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 George Henry Birkbeck, 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 thereof, that is to say :-
This Invention has for its object improvements in apparatus for lubricating
or supplying oil to axles, journals, or other moving parts of machinery, and
consists in so arranging apparatus that a sufficient quantity of oil is constantly
supplied to lubricate the parts required whilst they are in motion, the supply
of oil ceasing whilst they are at rest. The apparatus is also so arranged that
any excess of oil raised thereby at once flows back into the oil vessel without
being deteriorated by coming in contact with the moving frictional surfaces.
For this purpose an oil vessel or reservoir is supported in any convenient
manner near to the axle, journal, or other moving part of a machine which
requires lubrication. Within this vessel a force pump or other suitable
apparatus capable of raising the oil from one level to another is arranged so
as to raise a small quantity of the oil from time to time and deliver it on to
an incline or into a trough along which it flows, and in its passage the oil
flows over an opening or orifice, the extent of which is capable of regulation
by means of an adjustable pin or plug in order to regulate the quantity of

page_text: a screw plug which screws into the cross bar I2 on the trough H, the conical
point of the plug I¹ passing down into the orifice I, by which arrangement the
orifice I can be more or less closed by adjusting the position of the plug I¹, in
order to regulate the quantity of oil passing through the orifice I. When
the shaft or axis A ceases to revolve the supply of oil to the bearing also
ceases, thus avoiding any waste.
The mechanical means employed for raising the oil within the oil vessel X
so as to deliver it in regulated quantities to the conducting tube or passage
E may be greatly varied without departing from the nature of this Invention,
and the apparatus may also be suitably arranged for lubricating other moving
parts of machinery.
In witness whereof, I, the said George Henry Birkbeck, have hereunto
set my hand and seal, this Twenty-third day of September, in the year
of our Lord One thousand eight hundred and sixty-two.
G. H. BIRKBECK.
