IMPROVEMENTS IN APPARATUS FOR STONING RAISINS
Year: 1865

page_text: LETTERS PATENT to John Askew, of No. 27, Charles Street, Hampstead
Road, in the County of Middlesex, for the Invention of "IMPROVEMENTS
IN APPARATUS FOR STONING RAISINS."
Sealed the 2nd March 1866, and dated the 7th September 1865.
PROVISIONAL SPECIFICATION left by the said John Askew at the
Office of the Commissioners of Patents, with his Petition, on the 7th
September 1865.
I, JOHN.. ASKEW, of No. 27, Charles Street, Hampstead Road, in the
.County. of Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR STONING RAISINS," to be as follows:-
This Invention has, for its object improvements in apparatus for stoning
raisius. For these purposes a pair of rollers is used, one roller is of com-
paratively large and the other roller of comparatively small diameter. These
rollers are geared together, and are caused to move with a like surface speed.
The necks or axes of the rollers turn in suitable bearings, the axes of the
upper roller being pressed towards the lower roller, so as to keep the surfaces
of the two rollers constantly in contact. The surface of the smaller roller
is slightly grooved with longitudinal grooves, the larger roller is smooth. The
rollers are by preference of steel or iron. Motion is communicated to the
axis of the larger roller by a cog wheel, and the shaft on which the cog wheel
is fixed is driven by hand, or by any suitable power. In front of the pair of

page_text: rollers is a grating, the wires or bars of which are at a distance apart to admit
the stones of the raisins falling through, whilst the grating will support the
raisins as they are pressed towards the nip of the rollers. Each of the rollers
is provided with a doctor or scraper at the back. By the action of this com-
bined arrangement the flesh of the raisins will be crushed and pass through
between the rollers, but the stones will be retained, and will fall back away
from the rollers and through the grating above mentioned. The raisins are
placed on the grating, and are pressed forward thereon towards the nip_of_the
rollers by a blade or instrument, which is moved to and fro by hand, or
otherwise on the grating.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Askew in the Great Seal Patent Office on the 7th
March. 1866.
TO ALL TO WHOM THESE PRESENTS' SHALL COME, I, JOHN
ASKEW, of No. 27, Charles Street, Hampstead Road, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of September, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Askew, Her special licence that I, the said John Askew, my
executors, administrators, and assigns, or such others as I, the said John
Askew, 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 STONING RAISINS," upon the condition (amongst others) that I,
the said. John Askew, 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 John Askew, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-

page_text: formed, 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. apparatus for stoning
raisins. For these purposes a pair of rollers is used, one roller is of com-
paratively large and the other roller of comparatively small diameter. These
rollers are geared together, and are caused to move with a like surface speed.
The necks or axes of the rollers turn in suitable bearings, the axes of the
upper roller being pressed towards the lower roller; so as to keep the surfaces
of the two rollers constantly in contact. The surface of the smaller roller is
slightly grooved with longitudinal grooves; the large roller is smooth. The
rollers are by preference of steel or iron. Motion is communicated to the
axis of the larger roller by a cog wheel, and the shaft on which the cog
wheel is fixed is driven by hand, or by any suitable, power. In front of the
pair of rollers is a grating, the wires or.bars of which are at a distance apart
to admit the stones of the raisins falling through, whilst, the grating will
support the raisins as they are pressed towards the nip of the rollers. Each
of the rollers is provided with a doctor or scraper at the back. By the action
of this combined arrangement the flesh of the raisins will be crushed and
pass through between the rollers, but the stones will be retained, and will fall
back away from the rollers and through the grating above mentioned. The
raisins are placed on the grating, and are pressed forward thereon towards the
nip of the rollers by a blade or instrument, which is moved to and fro by
hand or otherwise on the grating."
Having thus stated the nature of my Invention, I will proceed more fully
to describe the manner of performing the same.

DESCRIPTION OF THE DRAWINGS.
Figures 1 and 2 show the two end elevations of the apparatus; Figure 3
shows a plan; and Figure 4 shows a transverse section. In each of these
Figures the same letters indicate the same parts.
a, a, is the framing of the apparatus; b and c are two rollers, the axes or
necks of which turn in suitable bearings. The upper and smaller roller b
rests on the lower and larger roller c: These rollers receive motion from a
cog wheel on the nave or centre of the fly wheel d, which turns on a fixed or
stud axis e, and motion is communicated to the fly wheel by the handle f.
The axes of the two rollers are geared together by the wheels h and i on the
respective axes. At the back of each roller is a doctor or scraper. The
doctor or scraper ; to the upper roller is fixed across the upper part of
the apparatus by keys, which pass through slots in the projecting studs k, k,

page_text: which pass through holes in the ends of the scraper or doctor j. The upper
edge of the shoot I serves as a doctor or scraper to the larger or bottom
roller. There is a ratchet wheel on one end of the axis of the larger roller,
..by which; and a catch or stop m, the rollers are prevented being. turned in the
wrong direction;'n is a grating, on to which the raisins are placed, and they
are pressed up towards the nip of the rollers by hand, or by a blade or
instrument, such as a paper cutter. By the revolution of the rollers the flesh
of the raisins is drawn through, whilst the stones fall back. and descend
through the grating..
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that what I claim is, the
combined arrangement of apparatus herein described.
In witness whereof, I, the said John Askew, have hereunto set my hand
and seal, this Seventh day of March, in the year: of our Lord. One
...thousand-eight. hundred and sixty-six.
