CERTAIN IMPROVE- MENTS IN APPARATUS FOR LUBRICATING FRICTIONAL SURFACES, AND IN THE LUDDIGAN TO BE EXPLOYED THEREWITH
Year: 1865

page_text: LETTERS PATENT to Joseph Wilson Lowther, of Manchester, in the
County of Lancaster, Agent, for the Invention of "CERTAIN IMPROVE-
MENTS IN APPARATUS FOR LUBRICATING FRICTIONAL SURFACES, AND IN THE
LUDDIGAN TO BE EXPLOYED THEREWITH
Sealed the 10th October 1865, and dated the 27th April 1865.
PROVISIONAL SPECIFICATION left by the said Joseph Wilson Lowther
at the Office of the Commissioners of Patents, with his Petition, on
the 27th April 1865.
I, JOSEPR WILSON LOWTHER, of Manchester, in the County of Lancaster,
Agent, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN APPARATUS FOR LUBRICATING FRICTIONAL SURFACES, AND IN
THE LUBRICANT TO BE EMPLOYED THEREWITH," to be as follows:-
My Invention relates to the lubrication of rotating or horizontally sliding
frictional surfaces by means of a certain description of lubricant in combination
with an improved apparatus, whereby the heat produced by the friction causes
the liquifaction and flow of the lubricant, so that the absence or presence of
friction and heat withholds or supplies the lubricant, which is the chief feature
of the Invention. The apparatus consists in a chamber to contain the lubri-
cant, from the bottom of which a tube projects, which surrounds another tube
containing three or more smaller tubes, all being vertical; this inner tube,

page_text: with its enclosed small tubes, projects below the outer tube and is in contact
with the frictional surface, so that the lubricant may become heated by the
friction and pass down the inner tubes from the chamber to the frictional parts.
The upper portion of the enclosed tube is prevented from falling through the
outer tube by a bracket or ledge thereon resting against the interior of the
chamber, and may be removed by a pin or rod attached for the purpose; the
fall or supply of the lubricant is also assisted by the constant tremulant move-
ment of the enclosed tube from being in contact with the frictional surface.
The lubricant consists of cocoa-nut oil, tallow, or equivalent grease and water,
combined and mixed together in such proportions as to render the compound
of a semi-solid consistency when not heated.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed.
by the said Joseph Wilson Lowther, in the Great Seal Patent Office on
the 26th October 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPHI
WILSON LOWTHER, of Manchester, in the County of Lancaster, Agent, send
greeting.
WHEREAS Her Most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of April, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did for Herself, Her heirs and successors, give and grant unto me, the
said Joseph Wilson Lowther, Her special license that I, the said Joseph
Wilson Lowther, my executors, administrators, and assigns, or such others as
I, the said Joseph Wilson Lowther, 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 " CERTAIN
IMPROVEMENTS IN APPARATUS FOR LUBRICATING FRICTIONAL SURFACES, AND IN THE
LUBRICANT TO BE EMPLOYED THEREWITH," upon the condition (amongst others)
that I, the said Joseph Wilson Lowther, 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.

page_text: NOW KNOW YE, that I, the said Joseph Wilson Lowther, 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 and accompanying Drawings (that is to say) :-
My Invention relates to the lubrication of rotating or horizontally sliding
frictional surfaces by means of an improved apparatus in combination with a
certain description of lubricant, whereby a tremulant motion which is given to
the same by its' frictional contact with the shaft, axle, or surface to which the
apparatus is applied, causes the lubricant to flow and gradually supply the
parts requiring lubrication, that is, during the time such parts, are in motion.
The apparatus consists of a chamber to contain the lubricant, from the bottom
of which a tube projects, which surrounds a circular plunger containing three
or more smaller tubes; this plunger may also if desired be formed of two or
more radial metal plates, the section of which would form a cross. To the
upper portion of this plunger, contained within the lubricant chamber or cup,
a bracket or ledge is secured, which rests upon the inner surface of such
chamber, thereby keeping the plunger in its proper position, and preventing it
protruding too far from the tube forming a portion of the lubricant chamber.
The bracket or ledge fixed to the plunger is perforated with any number of
holes required, according to the quantity of lubricant to be discharged. The
tremulant movement given to the plunger when in frictional contact with a
revolving shaft or other surface in motion, causes the lubricant to flow
regularly from the chamber or cup containing the same through the perfora-
tion of the bracket or ledge down the tubes to the frictional surfaces with
which such tubes are in contact. The plunger may be removed from the
chamber or cup by means of a pin or rod which is attached thereto. The
lubricant consists of cocoa-nut oil, tallow, or equivalent grease and water
combined and mixed together in such proportions as to render the compound
of a semi-solid consistency when not heated.
In order that the Invention may be better understood and explained in
detail I have hereunto attached a Sheet of Drawings, made about the full
size, similar letters of reference being marked upon corresponding parts of the
apparatus.
Fig. 1 represents the lubricator as it appears when attached or applied to a
pedestal or other bearing; this view also shews the plunger projecting from
the duct or pipe and bearing upon the surface of the revolving shaft. Fig. 2 is
a sectional elevation of the lubricant chamber or cup shewing the arrangement
and position of the plunger inside.

page_text: In Figs. 1 and 2 a, a, is the chamber or cup, from the bottom of which
projects the tube or pipe b, which forms the stem by which the lubricator is
attached to the bracket or bush c, and also the duct down which the lubricant
flows; d is the plunger, formed of tubes, which are supported or held in
position by the bracket or ledge e; the lubricant is contained in the cup above
this bracket, and perculates through the perforations thereof during the
tremulant action of the plunger, which is caused by its contact with the
revolving frictional surface f; the pin or rod g is attached to the plunger d,
in order that it can be removed when desired.
In witness, I, tho said Joseph Wilson Lowther, have hereunto set my
hand and seal, this Twenty-fourth day of October, in the year of our
Lord One thousand eight hundred and sixty-five.
JOSEPH WILSON LOWTHER. (L.S.)
