IMPROVEMENTS IN APPARATUS FOR DECORTICATING PEPPER
Year: 1884

page_text: I RUSSELL CRAMPTON of 5 Wellington Road Charlton in the County of Kent
Spice Grinder and Decorticator do hereby declare the nature of my invention for
"IMPROVEMENTS IN APPARATUS FOR DECORTICATING PEPPER" to be as follows:-
This Invention has for its object improvements in apparatus for decorticating
pepper.
The apparatus most commonly employed for decorticating consists of a cylindrical
stone or emery wheel mounted on an horizontal axis and contained in a cylindrical
casing of wire gauze to which also a rotary motion is imparted.
When such an apparatus is employed in the decortication of pepper a certain
proportion of the berries become separated into two parts each approximately
semi-globular. In order to allow these divided berries to escape through the
perforations of the outer casing as promptly as possible I make these perforations
considerably longer than they are broad indeed of a length greater than the
diameter of the pepper berry and of a width equal to half that length so that
although the perforation will retain the whole berries after decortication the
half berries may pass freely away in place of being retained and converted into
dust as at present.
These elongated holes also let through any long fragments of husk or of the
berry itself more freely than at present and this is advantageous.
I also provide ribs or projections within the cylindrical casing and these as the
casing revolve carry forward the berries and cause them to be operated on more
uniformly than when the interior surface of the perforated casing is without such
projections,

I RUSSELL CRAMPTON of 5 Wellington Road, Charlton in the County of Kent
Spice Grinder and Decorticator do hereby declare the nature of my invention for
"IMPROVEMENTS IN APPARATUS FOR DECORTICATING PEPPER " and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement :-

The apparatus most commonly employed for decorticating consists of a cylindrical
stone or emery wheel mounted on an horizontal axis and contained in a cylindrical
casing of wire gauze to which also a rotary motion is imparted.
When such an apparatus is employed in the decortication of pepper a certain
proportion of the berries become separated into two parts each approximately
semi-globular. In order to allow these divided berries to escape through the
perforations of the outer casing as promptly as possible I make these perforationa
considerably longer than they are broad indeed of a length greater than the
diameter of the pepper berry and of a width equal to half that length so that
although the perforation will retain the whole berries after decortication the half
berries may pass freely away in place of being retained and converted into dust
as at present.
These elongated holes also let through any long fragments of husk or of the
berry itself more freely than at present and this is advantageous.
I also provide ribs or projections within the cylindrical casing and these as the
casing revolves carry forward the berries and cause them to be operated on more
uniformly than when the interior surface of the perforated casing is without suc
projections.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
First. Forming the casing surrounding the stone or emery wheel and by which
the pepper is retained under treatment with oblong perforations in one direction
larger than the diameter of the-pepper berry and in the other direction less than
this measurement so that whilst whole berries are retained half berries may fall
through freely.
Second. Providing the said casing which also as well as the stone or emery
wheel is caused to revolve with ribs or projections substantially as described.
Dated this 19th day of June 1885.
