Year: 1869

page_text: LETTERS PATENT to John Daglish, of Done House, Seaham Harbour,
in the County of Durham, for the Invention of "IMPROVED APPARATUS
FOR LUBRICATING THE AXLES OF COAL TUBS AND OTHER WAGONS RUNNING ON
BAILS OR TRAMWAYS."
Scaled the 25th June 1869, and dated the 8th January 1869.
PROVISIONAL SPECIFICATION left by the said John Daglish at the
Office of the Commissioners of Patents, with his Petition, on the
8th January 1869.
I, JOHN DAGLISH, of Dene House, Seaham Harbour, in the County
of Durham, do hereby declare the nature of the said Invention for
"IMPROVED APPARATUS FOR LUBRICATING THE AXLES OF COAL TUBS AND OTHER
WAGONS RUNNING ON RAILS OR TRAKWAYS," to be as follows:-
This Invention consists in the application of circular brushes to
grease the axles of wheels of coal tubs or other wagons whilst moving
over the rails.
The oil, grease, or other lubricating matter is deposited in a box
below the shaft on which the brushes revolve in such a manner as to

page_text: allow part of the brushes to be constantly immersed in the lubricating
matter. The necessary motion to bring the lubricating matter up to the
axles is obtained by having a ring or disc of india-rubber or other suitable
material attached to one or two wheels or discs on the circular brush
shaft or on an auxiliary shaft, the ring or disc being of a sufficient
diameter to allow it to come in contact with the axle of the tub or
wagon, whereby a partial revolution of both discs and brushes is effected;
this movement brings the part of brushes immersed in the lubricating
matter up against the bearings of the axles, thereby causing them to be
uniformly and regularly lubricated. The india-rubber disc may be
attached either to the circulating brush shaft or to a second shaft which
gives motion to the brush shaft by means of spur gear or friction wheels
of india-rubber or other material, or by other suitable known means of
transmitting motion, so as to cause the brush shaft to revolve at a
greater or less rate than the india-rubber disc according as it may be
wanted, and in an opposite or in the same direction as required.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Daglish in the Great Seal Patent Office on
the 7th July 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
DAGLISH, of Dene House, Seaham Harbour, in the County of Durham,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of January, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Daglish, Her special licence
that I, the said John Daglish, my executors, administrators, and
assigns, or such others as I, the said John Daglish, 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 "IMPROVED APPARATUS FOR
LUBRICATING THE AXIES OF COAL TUBS AND OTHER WAGONS RUNNING ON RAILS OR

page_text: TRAMWAYS," upon the condition (amongst others) that I, the said John,
Daglish, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and scals, 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 I, the said John Daglish, 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, reference being had to the accompanying
Shoot of Drawings, and to the figures and letters marked thereon, that is
to say:
This Invention consists in the application of circular brushes of
bristles or equivalent materials to grease the axles of wheels of coal
tubs or other wagons whilst moving over the rails.
The oil, grease, or other lubricating matter is deposited in a box below
the shaft on which the brushes revolve in such a manner as to allow part
of the brushes to be constantly immersed in the lubricating matter.
The necessary motion to bring the lubricating matter up to the axles is
obtained by having a ring or disc of india-rubber or other suitable
material attached to one or two wheels or discs on the circular brush
shaft or on an auxilliary shaft, the ring or disc being of a sufficient
diameter to allow it to come in contact with the axle of the tub or
wagon, whereby a partial revolution of both discs and brushes is effected.
This movement brings the part of the brushes immersed, in, the
lubricating matter up against the bearing of the axles, thereby causing.
them to be uniformly and regularly lubricated. The india-rubber disc
may be attached either to the circular brush shaft or to a second shaft
which gives motion to the brush shaft by means of spur gear or, friction;
wheels of india-rubber or other material or by other, suitable known
means of transmitting motion, so as to cause the brush, shaft to revolve,
at a greater or less rate than the india-rubber disc, according as it may
be wanted, and in an opposite or in the same direction as required.
On the accompanying Sheet of Drawings is shown the arrangement of
my before-described improved apparatus which I prefer to employ.
Figure 1 shews a side elevation of the same with a coal tub in position

page_text: for being lubricated; Figure 2 shews a plan, and Figure 3 shews a
transverso section. Similar letters of reference indicate similar parts in
each of the Figures.
Between the line of rails A, A, and below the level of the same is
arranged a box B containing on each side a trough C, O, containing
oil, grease, or other lubricating matter, in which dip two circular
brushes D, D, carried by a shaft H, the brushes being of such a diameter
and in such positions that on a coal tub E passing over the box the
brushes will come in contact with and apply lubricating material to the
bearings of the axles F of the coal tub. In order to cause the brushes
to revolve so as to bring successively freshly lubricated portions thereof
uppermost, a disc G having an india-rubber rim may be fixed either
upon the shaft H of the brushes, as shewn at Figure 3, or upon a
separate shaft I, as shown at Figures 1 and 2, which disc in coming in
contact with the axles F as these pass over it is caused thereby to
revolve partially. If desired the bearings of the shafts H and I may be
supported on springs, as indicated in dotted lines in Figure 1, to allow of
their boing depressed in case the axles of the tubs are of varying heights
or bent. In the first before mentioned case the disc imparts such motion
(lirectly to the shaft H of the brushes, and in the second case it imparts
its motion to another disc K in contact therewith and fixed on the
shaft H. By the latter arrangement the brushes may be made to revolve
cach time to a greater extent than the disc G, according to the
proportion between the relative diameter of G and K.
Having thus described the nature of my Invention, and in what
manner the same is to be performed, I wish it to be understood that I do
not limit myself to the details of the arrangement thereof shewn on the
accompanying Drawings, as these may be variously modified without
departing from the nature of my Invention; thus it will be evident that
in place of an ordinary brush surface of bristles any suitable porous
clastic material capable of taking up the lubricating substance, such as a
sponge of india-rubber or other material, may be used. Also I am aware
that a non-porous surface of india-rubber has been employed for lubri-
cating the axles of coal tubs, and I do therefore not claim the use of
such material; but what I claim is, the construction and use of
apparatus for lubricating the axles of coal tubs and other wagons
wherein circular brushes of bristles or equivalent materials arranged

page_text: between the rails on which the coal tubs run are partially immersed in
lubricating matter contained in troughs or other receptacles, and pro
caused to convey such lubricating matter on to the bearings of the
axles of the coal tubs, substantially in manner herein-before set forth.
In witness whereof, I, the said John Daglish, have hereunto set
my hand and seal, this Sixth day of July, in the year of our
Lord One thousand cight hundred and sixty-nine.
