IMPROVEMENTS IN APPARATUS FOR PROVISIONAL
Year: 1868

page_text: LETTERS PATENT to Arthur Elliott, of Failsworth, near the City of
Manchester, Practical Mechanic, and John Barker, of Park Street
Iron Works, Oldham, in the County of Lancaster, Millwright and
Engineer, for the Invention of "IMPROVEMENTS IN APPARATUS FOR
PROVISIONAL SPECIFICATION left by the said Arthur Elliott and
John Barker at the Office of the Commissioners of Patents, with
their Petition, on the 25th March 1868.
We, ARTHUR ELLIOTT, of Failsworth, near the City of Manchester,
Practical Mechanic, and JoHN BARKER, of Park Street Iron Works,
Oldham, in the County of Lancaster, Millwright and Engineer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUS FOR LUBRICATING AXLES AND BEARINGS AND OTHER FRICTIONAL
SURFACES," to be as follows:-
Our Invention consists in applying the oil or other lubricating
material to the under surface of the axle or other article to be lubri-

page_text: cated; the oil is contained in a vessel formed in the hanger or pedestal,
and upon it floats a roller of cork or other substance, the upper surface
of which is held in contact with the article to be lubricated; as the axle
revolves the roller rotates and takes up a portion of oil which it deposits
on the axle, the oil is distributed along the bearing by making a recess
in the edge of the step. The floating roller is guided in slots made in
a frame which fits in a recess in the hanger or pedestal.
When our Invention is applied to lubricate the axles of railway
carriages we apply a filter or filters in the vessel containing the oil;
these filters collect the oil scraped off the axle by suitable scrapers and
filter it before it falls again into the cistern.
Our Invention may be
applied to lubricate the slides of planing
machines and other slides; the vessels with the oil and floating roller
are placed under the slide to be lubricated, and the roller applies the oil
to the slide as it passes to and fro.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Arthur Elliott and John Barker in the Great Seal
Patent Office on the 24th September 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ARTHUR
ELLIOTT, of Failsworth, near the City of Manchester, Practical Mechanic,
and JOHN BARKER, of Park Strect Iron Works, Oldham, in the County
of Lancaster, Millwright and Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of March, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Arthur Elliott and John Barker, Her
special license that we, the said Arthur Elliott and John Barker, our
executors, administrators, and assigns, or such others as we, the said
Arthur Elliott and John Barker, our 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

page_text: Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS FOR LUBRICATING
AXLES AND BEARINGS AND OTHER FRICTIONAL SURFACES," upon the condition
(amongst others) that we, the said Arthur Elliott and John Barker, our
executors or administrators, by an instrument in writing, under our or
their, or one of our or 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 we, the said Arthur Elliott and John Barker,
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 (that is to say) :-
:-
Our Invention consists in applying the oil or other lubricating
material to the under surface of the axle or other shaft to be lubri
cated; the oil is contained in a vessel formed in the hanger or pedestal,
and upon it floats a roller of cork or other substance, the upper surface
of which is held in contact with the shaft to be lubricated by the
buoyancy of the cork float, which is supported by the oil or other
lubricating material; as the axle revolves the cork roller rotates and
takes up a portion of oil which it deposits on the axle; the oil is
distributed along the bearing by making a recess in the edge of the
step. The floating roller is guided in slots made in a frame which fits
in a recess in the hanger or pedestal.
When the Invention is applied to lubricate the axles of railway
carriages we apply a filter or filters in the vessel containing the oil;
these filters catch the oil scraped off the axle by suitable scrapers, and
filter it before it falls again into the cistern.
Our Invention may be applied to lubricate the slides of planing
machines and other slides; the vessel with the oil and floating roller
is placed under the slide to be lubricated, and the roller applies the oil
to the slide as it passes to and fro.
And in order that our Invention may be fully understood and readily
carried into operation we will proceed to describe the accompanying
Sheet of Drawings, reference being had to the figures and letters marked
thereon.

page_text: Figure 1 is an elevation, Figure 2 is a longitudinal section, and
Figure 3 is a plan of a pedestal to which our improved apparatus for
lubricating axles and bearings is applied.
g.
a is the pedestal; b, the cap; c, the lower brass step; d, the upper
brass step; and e, the axle to be lubricated. The pedestal is made with
a cavity to contain the oil or other lubricant, and in this cavity is placed
the frame f, in which are slots for the axle of the cork or other roller
The lower step c is made with a slot through its lower surface to admit
the roller which floats upon the oil and bears against the under surface
of the axle e, consequently as the axle revolves the roller g rotates and
takes up a portion of the oil which it deposits on the axle. The oil is
distributed along the bearing by making a recess in the edge of the
steps, as shewn in Figure 2, and the oil that escapes from the ends of
the steps falls into the cavity in the pedestal, from which it is again
supplied to the under side of the axle by the roller g, as above described.
The set screw h is taken out when the cavity containing the oil requires
to be cleaned.
By means of this improved lubricating apparatus a great saving is
effected in the lubricating material, as it is applied over and over again
to the axle to be lubricated, and in labor as the cavity only requires to
be filled occasionally. The parts are also easy of access, and the frame f
with the roller g in its place can be taken out with facility for cleaning
or repairs without stopping the shaft.
Figures 4 and 5 are two views of a hanger to which our improved
lubricating apparatus is applied, the parts being very similar to those
above described are marked with corresponding letters of reference.
When our Invention is applied to lubricate the axles of railway
carriages we apply a filter or filters to the vessel or cavity containing
the oil or other lubricant; these filters catch the oil scraped off the axle
by suitable scrapers hinged to the filters or to the cistern, and filter
the oil before it falls again into the cistern.
Our Invention may be applied to lubricate the slides of planing
machines, horizontal engines, and other slides; the vessel with the oil
and floating roller is placed under the slide to be lubricated, and the
roller applies the oil to the slide as it passes to and fro.
Having thus stated the nature of our Invention, and described the
manner of performing the same, we declare that we claim,-

page_text: First. The improved arrangement of apparatus for lubricating axles
and bearings and other frictional surfaces, as shewn and described.
Secondly. The frame f for guiding the roller by which the oil or other
lubricant is supplied to the axle or other surface to be lubricated, as
shewn and described.
Thirdly. The application of a filter or filters to the axle box of railway
carriages, as described.
And, lastly. The application of scrapers to convey the oil or other
lubricant from the axle to the filters of railway axle boxes, as described.
In witness whereof, we, the said Arthur Elliott and John Barker,
have hereto set our hands and seals, this Twenty-second day of
September, One thousand eight hundred and sixty-eight.
