Year: 1859

page_text: LETTERS PATENT to Samuel Corbett, of Wellington, in the County of
Salop, Agricultural Implement Manufacturer, for the Invention of
"AN IMPROVEMENT OR IMPROVEMENTS IN PULPERS FOR PULPING FOOD FOR
TITLE
Sealed the 17th May 1860, and dated the 19th November 1859.
PROVISIONAL SPECIFICATION left by the said Samuel Corbett at the
Office of the Commissioners of Patents, with his Petition, on the
19th November 1859.
1.
I, SAMUEL CORBETT, of Wellington, in the County of Salop, Agricultural
Implement Manufacturer, do hereby declare the nature of the said Invention
for. "AN IMPROVEMENT OR IMPROVEMENTS IN PULPERS FOR PULPING FOOD FOR
CATTLE," to be as follows:-
My said Invention consists of the improvement or improvements in pulpers
for pulping turnips, mangold wurzel, and other kinds of food for cattle, herein-
after described: I fix upon a spindle two rings, upon which are placed cast
plates so as to form a cylinder or drum, the said plates being connected to the
said rings by screwing or otherwise. The said plates are cast with diamond or
cutting points on their convex or outer faces, and are furnished with apertures
opposite the points for the purpose. of admitting the cut or pulped food into
the interior of the cylinder or drum. The food is thus pulped without bruising

page_text: or mashing the root or article pulped, and the juice is neither injured nor lost.
The ends of the cylinder or drum are open, and the pulped food is discharged
at the said open ends. The cast plates can be readily removed and exchanged
by a farm labourer in the field without removing the cylinder, and the machine
be made suitable for actuating by horse or steam power instead of manual
power. Pulpers made according to my Invention are simple in construction
and economical in use. They are very durable but may be easily repaired
when necessary.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Corbett in the Great Seal Patent Office on the
19th May 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
CORBETT, of Wellington, in the County of Salop, Agricultural Implement
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of November, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-third year
of
Her, reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Samuel Corbett, Her special licence that I, the said Samuel
Corbett, my executors, administrators, and assigns, or such others as I, the
said Samuel Corbett, 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
"AN IMPROVEMENT OR IMPROVEMENTS IN PULPERS FOR PULPING FOOD FOR CATTLE,"
upon the condition (amongst others) that I, the said Samuel Corbett, 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 Samuel Corbett, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following

page_text: statement thereof, reference being had to the accompanying Drawings, and to
the figures and letters marked thereon, that is to say:-
My said Invention consists of the improvement or improvements in pulpers
for pulping turnips, mangold wurzel, and other kinds of food for cattle, herein-
after described. I fix upon a spindle two rings, upon which are placed cast-
iron plates in segments, so as to form a cylinder or drum, the said plates being
connected to the said rings by screwing or otherwise. The said plates are
cast with diamond or cutting points on their convex or outer faces, and are
furnished with apertures opposite the points for the purpose of admitting the
cut or pulped food into the interior of the cylinder or drum. The food is thus
pulped without bruising or mashing the root or article pulped, and the juice is
neither injured nor lost. The ends of the cylinder or drum are open, the
pulped food being discharged therefrom; and to further assist the discharge of
the food a heavy scraper is suspended loosely on the spindle passing through
the barrel, so as to maintain a vertical position therein, and prevent the food
being carried round. The cast plates can be readily removed and exchanged
by a farm labourer in the field without removing the cylinder, and the machine
be made suitable for actuating by horse or steam power instead of manuel
power. Pulpers made according to my Invention are simple in construction
and economical in use. They are very durable but may be easily repaired
when necessary.
In order that my said Invention may be fully understood, I shall now
proceed to describe the same, and for that purpose shall refer to the several
Figures on the Sheet of Drawings hereunto annexed, the same letters of
reference indicating corresponding parts throughout all the Figures.
DESCRIPTION OF THE DRAWINGS.
Figure 1 of the Drawings is a side elevation of my improved pulper ;
Figure 2 is a front view of the same; Figure 3 a cross section; and Figure 4
a longitudinal section. The details of my improvements will be better under-
stood by reference to the following Figures:-Figure 5 is a longitudinal
section of the barrel or cylinder and hopper, showing the manner of fixing the
cast plates to the ring; Figure 6 is a side view of the barrel; Figure 7 is an
end view of Figure 6; and Figure 8 an end view of one of the segments or
cast plates forming the barrel.
A is the hopper, and B a grating in its interior; C, the cylinder or barrel ;
D, the cutters; and E, the openings to admit the pulped food to the interior
of the barrel; F, the shaft or spindle on which the barrel is keyed; G is the
scraper or weight for clearing the inside of the barrel; H a grate round the

page_text: under side of the barrel to prevent the falling of large pieces of root; J, the
rings, to the interiors of which the cast plates are secured; K, the arms which
support the barrel; L, a platform to receive the pulped food; M, arches
enclosing the ends of barrel; N, a slide covering an opening in the side
thereof; and P is the fly wheel.
Having thus described the nature of my said Invention, and the manner
of carrying the same into practical effect, I would have it understood that
what I claim is, the constructing agricultural implements called pulpers with
the cylinder or barrel made of cast-iron plates, having diamond or cutting
points screwed, cast on, or otherwise fastened to its convex or outer side, in
the manner herein set forth aud described.
In witness whereof, I, the said Samuel Corbett, have hereunto set
my hand and seal, this Sixteenth day of May, in the year of our
Lord One thousand eight hundred and sixty.
SAMUEL CORBETT. (L.S.)
