Year: 1855

page_text: LETTERS PATENT to William Henry Gauntlett, Engineer, of Banbury,
Oxfordshire, for the Invention of "IMPROVEMENTS IN APPARATUS FOR
Sealed the 10th September 1855, and dated the 28th March 1855.
PROVISIONAL SPECIFICATION left by the said William Henry Gauntlett
at the Office of the Commissioners of Patents, with his Petition, on the
28th March 1855.
I, WILLIAM HENRY GAUNTLETT, Engineer, of Banbury, Oxfordshire, do
hereby declare the nature of the Invention for "IMPROVEMENTS IN APPARATUS
FOR CUTTING OR PULPING TURNIPS AND OTHER ROOTS" to be as follows:-
This Invention consists of making the knives or cutters of cylindrical
machines and also of disc machines by pressing angular or bent cutters out of
the sheet steel surface of the cylinder or disc (when such cylinders or discs are
used); the front or fixed plate of the machine is grooved to correspond with
the form of the cutters so pressed out of the sheet steel.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Henry Gauntlett in the Great Seal Patent Office
on the 28th September 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY GAUNTLETT, Engineer, of Banbury, Oxfordshire, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of March, in the year of our
Lord One thousand eight hundred and fifty-five, in the eighteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Henry Gauntlett, Her special licence that I, the said
William Henry Gauntlett, my executors, administrators, and assigns, or such
others as I, the said William Henry Gauntlett, 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 CUTTING OR PULPING TURNIPS AND OTHER
Roors," upon the condition (amongst others) that I, the said William Henry
Gauntlett, by an instrument in writing under my hand and seal, 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 William Henry Gauntlett, 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 (that is to say) :—
This Invention consists of making the knives or cutters of cylindrical
machines and also of disc machines by pressing angular or bent cutters out of
the sheet steel surface of the cylinder or disc; and when such cylinders or discs
are used, the front or fixed plate of the machine is grooved to correspond with
the form of the cutters so pressed out of sheet steel.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 is a side elevation of a machine constructed according to my Inven-
tion, having a cylindrical cutter; Figure 2 is an end elevation; and Figure 3

page_text: is a plan thereof; Figure 4 is a section of the cylindrical cutter used in the
machine, but shown on a larger scale; Figure 5 is a longitudinal section;
Figure 6 is part of a horizontal section; and Figure 7 shows part of the
surface of the cylinder laid open as if on a plain. In each of these Figures
the same letters are used to indicate the same parts.
The parts in Figures 1, 2, and 3 are to a scale of one and a half inches to
the foot, and the parts in Figures 4, 5, 6, and 7 are to a scale of six inches
to a foot.
The peculiarity of the Invention, as above stated, consists of forming the
angular or bent cutters out of the sheet of metal of which the general surface
of the cylinder is formed, in place of making the cutters separate and fixing
them on to a cylinder, as heretofore practised; and although I have only
shewn a cylinder, which is the form I prefer, it is evident that similar cutters
could be formed on and out of the surface of a disc. Each cutter a, a, is
bent out from and is formed of a portion of the same metal as the periphery
of the cylinder. The arrangement and shape of the cutters a, a, shown in
Figure 7, are what I prefer, but the same may be varied. The front or
fixed plate of the machine is grooved to correspond with the projecting cutters
a, a, as shown. The general combination of the machine is very similar to
what has heretofore been used; I do not, therefore, claim the same when the
cutters used are separate instruments from the barrel or cylinder.
Having thus described the nature of my said Invention, and the manner
of performing the same, I would have it understood that what I claim is, the
manufacture of cylindrical or disc cutters, herein described, for cutting or
pulping turnips and other roots.
In witness whereof, I, the said William Henry Gauntlett, have hereunto
set my hand and seal, this Twenty-seventh day of September, in the
year of our Lord One thousand eight hundred and fifty-five.
Witness,
WILLIAM HENRY GAUNTLETT. (L.S.)
BERNHARD SAMUELSON, of Redcar,
Ironmaster.
