Year: 1875

page_text: LETTERS PATENT to Matthew Burnett, Engineer, and Henry Hornsby,
Viewer, both of Spennymoor, in the County of Durham, for the
Tuvention of "A NEW OR IMPROVED LUBRICATOR FOR JOHPWATO "
Scaled the 4th January 1876, and dated the 22nd July 1875.
PROVISIONAL SPECIFICATION left by the said Matthew Burnett and
Henry Hornsby at the Office the Commissioners of Patents, with
their Petition, on the 22nd July 1875
WC, MATTHEW BURNETT, Engineer, and HENRY HORNSBY, Viewer,
both of Spennymoor, in the County of Durham, do hereby declare the
nature of the said Invention for "A NEW OR IMPROVED LUBRICATOR FOR
JOURNALS," to be as follows:-
The apparatus consists of a closed vessel made wholly or partly of
glass, and as applied to coal tub journals and other carriage axle
journals, by preference made with a flange or lugs for fastening it to
the under framing of the carriage. The object of making it wholly or
partly of glass is to enable the quantity of oil or other lubricant to be
observed from the outside. The lower part of the apparatus fits over

page_text: In this
and rests on the upper part of the axle, and a passage is here formed in
it which communicates with the interior or oil chamber.
passage is placed a ball which is caused to revolve by frictional contact
with the journal; on this ball rests a ball-shaped pad caused to revolve
by frictional contact with the aforesaid ball which may be made of hard
wood, china, or other suitable material
When this apparatus is applied to the journals of ordinary shafting
the plummer block may be made with a corresponding hole for inserting
a neck on the apparatus, in which neck the aforesaid passage is formed
for the reception of the balls.
The balls fit the passage well but so as to be able to rovolve freely
therein.
Instead of balls rollers may be used, but-we-prefer the former.
The oil chamber has a hole which is closed by a screwed stopper for
foon in the lower part.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Matthew Burnett and Henry Hornsby in the
Great Seal Patent Office on the 22nd January 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, MATTHEW
BURNETT, Engineer, and HENRY HORNSBY, Viewer, both of Spennymoor,
in the County of Durham, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of July, in the year 2
of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Hor heirs and suc-
cessors, give and grant unto us, the said Matthew Burnett and Henry
Hornsby, Her special licence that we, the said Matthew Burnett and
Henry Hornsby, our executors, administrators, and assigns, or such a
others as we, the said Matthew Burnett and Henry Hornsby, our
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during

page_text: 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
"A NEW OR IMPROVED LUBRICATOR FOR JOURNALS," upon the condition
(amongst others) that we, the said Matthew Burnett and Henry
Hornsby, our executors or administrators, by an instrument in writing
under our, or their, or one of their hands and scals, should par-
ticularly 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 we, the said Matthew Burnett and Henry
Hornsby, do hereby declare the nature of our 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 accompanying Drawings, and to the letters of reference marked'
thereon, that is to say.
Apparatus constructed according to this Invention consists of a closed
vessel formed with a neck or passage leading to the shaft or other
revolving or moving part which is to be lubricated In this neck or
passage we place a ball which receives revolving motion by frictional
contact with the journal or part to be lubricated and in accordance with
the speed thereof, this ball fits the passage or interior of the neck well,
but so as to be able to revolve freely therein, the ball revolves against
a ball-shaped or other pad or cushion in the passage or interior of the
neck, the oil or other lubricant is thus transferred from the pad to the
ball, and thence to the part which is to be lubricated
The vessel may
be made wholly or partly of glass to enable the quantity of oil or other
lubricant to be observed from the outside The balls may be made of
hard wood, china, glass, metal, or other suitable material.
And in order that this our Invention may be more fully understood,
we will now proceed to describe some modes of carrying the same into
effect.

page_text: according to this Invention in the form of an axle box, and suitable for
lubricating the axle journals of coal tubs and other carts or carriages.
The apparatus is made with a flange or lugs for fastening it to the
under framing of the carriage by means of two bolts, as shown. The
front side of the chamber D containing the oil or other lubricant is
formed of thick glass, as shown The lower part of the apparatus fits
over and rests on the upper part of the axle F, and a passage C is here
formed in it which communicates with the interior of the oil chamber D.
In this passage is placed a ball A which is caused to revolve by frictional
contact with the journal, and of course in accordance with the revolving 1
speed of the axle B is a ball-shaped or otherwise formed pad which
rests on the ball A. The oil chamber D has in the lower part a hole
which is closed by a screwed stopper E and serves for filling the
apparatus.
In order to be readily applied without cutting away the under framing
of the carriage much the oil chamber D is by preference made to
overhang the journal, as shown The oil chamber may be made entirely
of metal, but we prefer to make it as shown.
Figure 4 is a sectional clevation of a lubricator suitable for shafting
in general, for connecting rods, and for such other moving parts of
machinery, whereby revolving motion can be given to the lubricating
ball in the apparatus. The oil chamber D is here made of glass, the
lower part or neck is of brass and is screwed or fitted into a corre-
sponding hole in the plummer block, connecting rod end, or other part
of machinery in case it is applied to a connecting rod end, the ball A.
revolves in contact with the crank, crank pin, or cross head pin, thus
receiving more or less revolving motion therefrom. The neck is formed
with a passage C which communicates with the oil chamber D. On the
ball A rests a pad B which may be ball-shaped or otherwise, E is a
screwed stopper wluch closes the filling holc.
Instead of one ball A two or more superposed and in frictional
contact with one another may be applied in the neck or passage C.
Instead of balls, rollers may be used, but we prefer the former.
And having thus fully described the nature of this Invention, and
modes of carrying the same into effect, we declare that we claim,―
Firstly. A ball or roller in fictional contact with the part to be

page_text: lubricated and receiving the lubricant from a pad, all arranged in or
with a closed lubricating vessel, substantially as set forth.
Secondly The application of glass to the bodies or oil vessels of
lubricators, constructed substantially as set forth.
Thirdly. The application of lubricators, constructed substantially as
set forth, to wheel axles in the form of axle boxes, substantially as set
forth.
In witness whereof, we, the said Matthew Burnett and Henry
Hornsby, have hereunto set our hands and seals, this Twentieth
day of January, in the year of our Lord One thousand eight
hundred and seventy-six.
