Year: 1875

page_text: LETTERS PATENT to Robert Hudson, of Gildersome, near Leeds, in
the County of York, for the Invention of "IMPROVEMENTS IN THE
CONSTRUCTION OF WAGONS AND CORVES' FOR [CARRYING COALS, CLAY, Sand,
ORES, OR OTHER MATERIALS"
PROVISIONAL SPECIFICATION left by the said Robert Hudson at the
Office of the Commissioners of Patents, with his Petition, on the
28th July 1875.
I, ROBERT HUDSON, of Gildersome, near Leeds, in the County of
York, do hereby declare the nature of the said Invention for "IMPROVE-
HENTS IN THE CONSTRUCTION OF WAGONS AND CORVES' FOR CARRYING COALS,
CLAY, SAND, ORES, OR OTHER MATERIALS," to be as follows
"
-
This Invention relates to improvements in the construction of wagons
and corves for carrying coals, clay, sand, ores, or other materials,
and consists in forming the body of the wagon or "corf" of one or more
sheets of steel, iron, zinc, or other suitable material, bent round and

page_text: rivetted to pieces of angle or bar iron of a semicircular, oval, or other
required shape the end plates are then attached, and the shell is ready
for the buffers, wheels, axles, and other parts.

When preferred the angle iron may be dispensed with by flanging
the plates and then rivetting the plates together after being bent to 5
the required form. These "corves' or wagons may be also made
wholly or partly of steel, iron, wood, or zinc, used either in combination
or separately.

Another part of my Invention consists in the "draw bar being
made to pass under the body of "corf or wagon and then up each end 1
to the top hoop. By this arrangement any strain on the end plates is
transmitted to the "draw bar."
My Invention further consists in allowing one wheel on each axle to
be loose and the other fast, so that one wheel can revolve and the other
be stationary at the same time, thus giving greater facility for turning 1
the wagons or corves or running them round curves.

"
Another part of my Invention consists in applying a cap (under the
centre of each axles) to the body of the wagon or "corf" instead of
one at each "neck, thus leaving the "necks" free and exposed for
lubrication.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Hudson in the Great Seal Patent Office
on the 28th January 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
HUDSON, of Gildersome, near Leeds, in the County of York, send a
greeting
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of July, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Robert Hudson, Her special
licence, that I, the said Robert Hudson, my executors, administrators,

page_text: and
assigns, or such others as I,' the said Robert Hudson, 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 "IMPROVE-
MENTS IN THE CONSTRUCTION OF WAGONS AND 'CORVES' FOR CARRYING COALS,
CLAY, SAND, ORES, OR OTHER MATERIALS," upon the condition (amongst
others) that I, the said Robert Hudson, my executors or admini-
strators, 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 Robert Hudson, 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 following statement, reference being had to the accom-
panying Drawings and to the letters of reference marked thereon,
that is to say
--
}
This Invention relates to improvements in the construction of wagons
and " corves for carrying coals, clay, sand, ores, or other materials,
and consists in forming the body of the wagon or "corf" of one or more
sheets of steel, non, zinc, or other suitable material, bent round and
rivetted to pieces of angle or bar iron of a semicircular, oval, or other
required shape, the end plates are then attached, and the shell is ready
for the buffers, wheels, axles, and other parts.
When preferred the angle iron may be dispensed with by flanging
the plates, and then vetting the plates together after being bent to the
required form. These "corves" or wagons may be also made wholly
or partly of steel, iron, wood, or zinc, used either in combination or
separately
Another part of my Invention consists in the diaw bar being mado
to pass under the body of "corf 'or wagon and then up each end to
the top hoop By this arrangement any strain on the end plates is
transmitted to the draw bar."

page_text: Another part of the improvement consists in forming the corves
wholly or partly of wood and metal, as shown on Drawings, Figures 3, 4,
and 5; the body of the corf is formed of wood lags L, shouldered down
to fit against the wood ends M, as shewn, the lags are kept in their
places by curved bars E running round the outside, and through
which the lags are rivetted, bolted, or screwed, the draw bar is then
put on similarly to that shewn on Figures 1 and 2, and the corf is ready
to receive the wheels, buffers, top hoop, and other parts necessary to
complete it.
Another part of the improvements consists in having one wheel fast
and the other loose on the same axle, so that one can revolve indepen-
dently of the other, thus giving greater facility for running round curves
and preventing wear at the same time, as when running on a straight
road both wheel and axles go round together.
Another part of the improvement consists in casting the wheels with
a countersink of a hexagon shape on one side, as shown at G, Figure 6,
into which the ends of the axle are rivetted, thus preventing the wheel
from turning round without the axle.
I wish it to be understood that I do not confine myself to the preciso
shape of the angle bars H, as shewn at Figures 1 and 2, as they may be
bent wholly or partly of an oval or semicircular form if desired.
Having now described the nature of my Invention, and the manner
in which the same may be performed, I would remark in conclusion
that I do not limit myself to the exact details and configuration of parts
I have explained and shewn, as the same may of course be varied or
modified without in any way departing from the nature of my Inven-
tion, but what I do claim and desire to be secured to me by Letters
Patent is,―
Firstly. The arrangement, construction, and combination of the
various parts forming the corves, substantially as and for purposes
herein set forth.
Secondly. The construction of the draw bar as applied to corves and
other wagons as set forth

page_text: Fourthly Forming one wheel loose on cach axle of corves and other
wagons constructed substantially as set forth.
In witness whereof, I, the said Robert Hudson, have hercunto set
my hand and seal, this Twenty-seventh day of January, in the
year of our Lord One thousand eight hundred and seventy-
SIX.
