IMPROVEMENTS IN MACHINERY FOR CUTTING CAROMEL AND SUCH LIKE SUBSTANCES
Year: 1873

page_text: LETTERS PATENT to Thomas Black Callard, of 1, Queen's Terrace,
Saint John's Wood, in the County of Middlesex, for the Invention
of "IMPROVEMENTS IN MACHINERY FOR CUTTING CAROMEL AND SUCH LIKE
SUBSTANCES."
Sealed the 2nd April 1874, and dated the 7th October 1873.
PROVISIONAL SPECIFICATION left by the said Thomas Black Callard
at the Office of the Commissioners of Patents, with liis Petition,
on the 7th October 1873.
I, THOMAS BLACK CALLARD, of 1, Queen's Terrace, Saint John's
Wood, in the County of Middlesex, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN MACHINERY FOR CUTTING CAROMEL
AND SUCH LIKE SUBSTANCES," to be as follows:-
This Invention has for its object improvements in machinery for
cutting caromel and such like substances.
In order to form caromel and such like substances into the oblong
pieces required for the market, it is first when in a melted state, poured

page_text: .
upon a slab in the usual manner, this slab is then placed upon a
reciprocating frame having toothed racks upon it, one on either side;
this frame is supported in suitable guides on a fixed frame which
carries an horizontal axis at right angles to the racks. The axis has two
pinions upon it which gear with the racks, and between the pinions and
fixed on the axis are a series of circular knives arranged at distances
apart corresponding to the size of the pieces it is desired to cut. When
by turning the axis by hand or by power the slab is caused to pass
beneath it the knives come close to but not into absolute contact with
its surfaco and they divide the caromel or such like substance which the :
slab supports into a number of parallel strips.
After having passed beneath the cutters the slab with the material
upon it is pushed on along guide rails, whilst the reciprocating frame
returns to receive another slab with material to be cut, the cut strips
still resting on the slab are conveyed along the guide rails to another
reciprocating frame which is moved by racks and pinions, and so carried
under another axis having also circular knives upon it by means of
which the strips of caromel or other such like substance are divided
into pieces of any length desired. The slabs with the material upon
them are slidden off from the second reciprocating frame into a rack
having a number of compartments in it to receive a series of slabs one
over the other.
At the commencement of the operation when the rack is empty, it is
suspended in its highest position, and it receives the first slab into its
lowest compartment; then it is caused to descend to bring the next E
compartment into position to receive a slab, and so each compartment is
filled in turn, the rack being made to descend step by step until it is full,
and then it is conveyed away.
The caromel or such like material is afterwards removed from the
slabs and packed in boxes or otherwise.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
BLACK CALLARD, of 1, Queen's Terrace, Saint John's Wood, in the
County of Middlesex, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Hor
Letters Patent, bearing date the Seventh day of October, in the
year of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Thomas Black Callard, Her
special license that I, the said Thomas Black Callard, my executors,
administrators, and assigns, or such others as I, the said Thomas
Black Callard, 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 MACHINERY FOR CUTTING CAROMEL AND
SUCH LIKE SUBSTANCES," upon the condition (amongst others), that I, the
said Thomas Black Callard, 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 Thomas Black Callard, 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 has for its object improvements in machinery for
cutting caromel and such like substances.
In order to form caromel and such like substances into the oblong
pieces required for the market, it is first when in a melted state, poured
upon a slab in the usual manner; this slab is then placed upon a table

page_text: having upon it the caromel or such like substance requiring to be cut.
It is first placed on to the table or frame between the two racks which
gear with the toothed wheels on the axis b, and the pawls g carried at
the ends of these racks drop down behind the slab. When the axis b
is turned by the crank handle upon it the pawls at the ends of the
racks carry the slab along with them and pass it below the axis 6,
whereby the knives upon this axis are caused to cut the caromel or such
like substance into strips, and the slab is brought into position upon the
table a for the two racks which gear with the toothed wheels on the
axis c to come one on either side of it. When these two racks have
been moved along, the sides of the slabs and the pawls g. at their end
have dropped down behind the end of the slab; the slab is carried under
the axis c by turning the crank handle upon it, and thereby the strips
of caromel or such like substance upon the slab are divided into pieces
of the size desired. The slab with the material upon them may then be
taken away or slid into a rack as above described.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I claim, the
combined arrangement of machinery substantially as herein described,
for cutting caromel and such like substances.
In witness whereof, I, the said Thomas Black Callard; have
hereunto set my hand and seal, this Seventh day of April,
in the year of our Lord One thousand eight hundred and
seventy-four.
