IM- PROVEMENTS IN THE CONSTRUCTION OF CARRIAGE AXLE BOXES
Year: 1875

page_text: LETTERS PATENT to Honry Bernoulli Barlow, of Manchester, in
the County of Lancaster, Patent Agent, for the Invention of "IM-
PROVEMENTS IN THE CONSTRUCTION OF CARRIAGE AXLE BOXES."-A com-
munication from abroad by Marie Eutrope Adolphe Genies, of
Paris, France.
PROVISIONAL SPECIFICATION left by the said Henry Bernoulli
Barlow at the Office of the Commissioners of Patents, with his
Petition, on the 5th June 1875.
I, HENRY BERNOULLI BARLOW, of Manchester, in the County of
Lancaster, Patent Agent, do hereby declare the nature of the said In-
vention for "IMPROVEMENTS IN THE CONSTRUCTION OF CARRIAGE AXLE BOXES,"
being a communication to me from abroad by Marie Eutrope Adolphe
Genies, of Paris, France, to be as follows:-
Cast-iron axle boxes of the ordinary construction are very objectionable,
as when properly case hardened they are very liable to break, and when
only slightly case hardened they are soon worn out. Now this Inven-

page_text: tion consists in making the axle box in two parts, screwed or otherwise
connected together. The box which fits on the axle is made of drawn
hardened iron or steel or other metal, and the bush is of cast iron or
other metal.
By this improved mode of constructing axle boxes they are rendered i
more durable and work with less friction than those made in the
ordinary manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Bernoulli Barlow in the Great Seal Patent
Office on the 1st December 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BERNOULLI BARLOW, of Manchester, in the County of Lancaster, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of June, in the year of
our Lord One thousand cight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry Bernoulli Barlow, Her special
licence that I, the said Henry Bernoulli Barlow, my executors, adminis-
trators, and assigns, or such others as I, the said Henry Bernoulli
Barlow, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 THE CONSTRUCTION OF CARRIAGE AXLE BOXES," a com-
munication to me from abroad by Marie Eutrope Adolphe Genies, of
Paris, France, upon the condition (amongst others) that I, the said.
Henry Bernoulli Barlow, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and scals,
should particularly describe and ascertain the nature of the said In-
vention, 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 Henry Bernoulli Barlow, 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, that is to say :-
Cast-iron axle boxes of the ordinary construction are very objectionable,
as when properly case hardened they are very liable to break, and when
only slightly case hardened they are soon worn out. Now this Inven-
tion consists in making the axle box in two parts, screwed or otherwiso
connected together. The box which fits on the axle is made of drawn
hardened, iron or steel or other metal, and the bush is of cast iron or
other metal.
By this improved mode of constructing axle boxes they are rendered
more durable, and work with less friction than those made in the
ordinary manner.
And in order that this Invention may be fully understood and readily
carried into operation, I will proceed to describe the accompanying
Sheet of Drawings, which represents a longitudinal section of the
improved carriage axle box.
The axle box A fitting on the axle is made of drawn hardened iron or
steel or other metal, and it is screwed at x into the cast iron or other
metal bush B, or the two parts may be soldered together if preferred.
The end of the axle box is closed by a brass or other plug in the ordinary
manner. By thus constructing the axle box in two parts the part A
can be made hard without diminishing its strength, thereby reducing
friction.
Having thus stated the nature and particulars of the Invention com-
municated to me by the within named Marie Eutrope Adolphe Genies, I
declare that I claim constructing carriage axle boxes in two parts, in
the manner and for the purposes described.
In witness whereof, I, the said Henry Bernoulli Barlow, have
hereto set my hand and seal, this Twenty-sixth day of November,
One thousand eight hundred and seventy-five.
