Year: 1859

page_text: LETTERS PATENT to Ebenezer Partridge, of Stourbridge, in the County
of Worcester, Engineer and Ironfounder, for the Invention of "AN
IMPROVEMENT IN THE MANUFACTURE OF PIPE' BOXES FOR CART AND WAGON
AXLES."
Sealed the 12th July 1859, and dated the 14th April 1859.
PROVISIONAL SPECIFICATION left by the said Ebenezer Partridge at the
Office of the Commissioners of Patents, with his Petition, on the
14th April 1859.
I, EBENEZER PARTRIDGE, of Stourbridge, in the County of Worcester,
Engineer and Ironfounder, do hereby declare the nature of the said Invention
for "AN IMPROVEMENT IN THE MANUFACTURE OF PIPE' BOXES FOR CART AND
WAGON AXLES," to be as follows:-
My Invention consists in forming conical steel bearings in the ends of
conical cast-iron boxes, by casting the iron on to two conical collars shaped
and prepared to fit the axles to which the boxes are to be fitted. After the
boxes are cast I take them hot from the mould, and plunge them in water.
The two collars take the entire bearing of the axle, and the space left
between them and the axle when in the box forms a grease or lubricating
chamber.

by the said Ebenezer Partridge in the Great Seal Patent Office on the
14th October 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EBENEZER
PARTRIDGE, of Stourbridge, in the County of Worcester, Engineer and Iron-
founder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of April, in the year of our Lord One
thousand eight hundred and fifty-nine, in the twenty-second year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Ebenezer Partridge, Her special licence that I, the said Ebenezer Partridge,
my executors, administrators, and assigns, or such others as I, the said
Ebenezer Partridge, 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 Ire-
land, the Channel Islands, and Isle of Man, an Invention for "AN IMPROVE-
MENT IN THE MANUFACTURE OF 'PIPE' BOXES FOR CART AND WAGON AXLES,"
upon the condition (amongst others) that I, the said Ebenezer Partridge,
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 Ebenezer Partridge, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the fol-
lowing statement thereof, reference being had to the Drawings hereunto
annexed, that is to say:-
My Invention consists in forming conical steel bearings in the ends of
conical cast-iron boxes by casting the iron on to two conical collars shaped
and prepared to fit the axles to which the boxes are to be fitted. After the
boxes are cast I harden them in water. The two collars take the entire
bearing of the axle, and the space left between them and the axle when in the
box forms a grease or lubricating chamber.
Figure 1 is an external elevation, and Figure 2 a section of a pipe axle
box with my improvement applied thereto. A, A, is the box; B, B, are the

page_text: conical steel collars which form the bearings for the axles; C is a lubricating
chamber. The dotted lines a, a, represent hollows formed in the collars, into
which the iron flows while being cast. The casting is performed in the
ordinary manner.
And having now described the nature of my said Invention and in what
manner the same is to be performed, I declare that I claim casting conical
pipe axle boxes on to conical steel collars which take the bearings of the axle,
as herein-before descibed.
In witness whereof, I, the said Ebenezer Partridge, have hereunto set
my hand and seal, this Sixth day of October, One thousand eight
hundred and fifty-nine.
