IMPROVEMENTS IN APPARATUS FOR LUBRICATING LOCOMOTIVE AND OTHER AXLES."
Year: 1862

page_text: LETTERS PATENT to Bewicke Blackburn, of York Buildings, Adelphi,
in the County of Middlesex, for the Invention of "IMPROVEMENTS IN
APPARATUS FOR LUBRICATING LOCOMOTIVE AND OTHER AXLES."
PROVISIONAL SPECIFICATION left by the said Bewicke Blackburn at the
Office of the Commissioners of Patents, with his Petition, on the
2nd April 1862.
I, BEWICKE BLACKBURN, of York Buildings, Adelphi, in the County of
Middlesex, do hereby declare the nature of the Invention for "IMPROVEMENTS
IN APPARATUS FOR LUBRICATING LOCOMOTIVE AND OTHER AXLES," to be as
follows:-
These improvements have reference to a previous Patent granted to me
and dated 13th June 1861 (No. 1524) and are as follows:-
First, instead of placing the packing or stuffing used for spreading the oil
on the journal below the journal, it is fixed above the centre of the journal
and in contact with it, and in such a position that the packing and the brass
bearing shall wear away simultaneously together, and thus the packing remain
always in contact with the upper part of the journal as long as the brass
bearing lasts.
Secondly, in so varying the construction of the vessel which holds the oil
that while the lower part of it is made oil-proof as before, the upper part is

page_text: formed of porous material, so that when the carriage is in motion and the
oil thereby splashed up to the porous material at the upper part of the vessel
the oil percolates through it and flows down to the journal beneath.
Thirdly, one end of a pipe made of flexible material is fitted to an aperture
in the upper compartment of the axle box, or in the vessel introduced into
the compartment. A float is attached to this pipe which buoys it up above
the surface of the oil. The motion of the carriage splashes the oil up to the
mouth, whence it flows through the pipe down to the journal beneath.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Bewicke Blackburn in the Great Seal Patent Office on the
1st October 1862.
. TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BEWICKE
BLACKBURN, of York Buildings, Adelphi, in the County of Middlesex, send
greeting.
WHEREAS, Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second 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 Bewicke Blackburn, Her special licence that I, the said Bewicke
Blackburn, my executors, administrators, and assigns, or such others as I, the
said Bewicke Blackburn, 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
"IMPROVEMENTS IN APPARATUS FOR LUBRICATING LOCOMOTIVE AND OTHER AXLES,"
upon the condition (amongst others) that 1, the said Bewicke Blackburn,
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.
NOW KNOW YE, that I, the said Bewicke Blackburn, do hereby declare
the nature of the said Invention, and in what manner the same is to be;

page_text: performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
These improvements have reference to a previous Patent granted to me
and dated 13th June 1861 (No. 1524) and are as follows:-
Instead of placing the packing or stuffing used for spreading the oil on
the journal below the journal it is fixed above the centre of the journal and
in contact with it, and in such a position that the packing and the brass
bearing shall wear away simultaneously together, and thus the packing
remains always in contact with the upper part of the journal as long as the
bearing lasts.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a longitudinal section; and Figure 2 a transverse section of
apparatus applied to an axle according to my Invention.
Instead of placing the packing or stuffing used for the purpose of spreading
the oil in a position below the centre of the journal, woollen or other capillary
fillets W, W, Figure 2, are fixed to the brass bearing B by the hooks K, K,
or by other ordinary means in a position above the centre of the journal J
and in contact with it. Thus they are in such a position that they can only
wear away as the brass itself wears away, and they therefore remain in
contact with the journal, and do not require renewing as long as the brass
bearing lasts.
In witness whereof, I, the said Bewicke Blackburn, have hereunto
set my hand and seal, this Twenty-fourth day of September, in the
year of our Lord One thousand eight hundred and sixty-two.
BEWICKE BLACKBURN. (L.S.)
