IMPROVEMENTS IN MEANS OR APPARATUS FOR EFFECTING THE CHOPPING OR SEPARATION OF ANIMAL AND VEGETABLE SUBSTANCES
Year: 1863

page_text: LETTERS PATENT to William Francis Dearlove, of 263, Goswell Road, in
the County of Middlesex, for the Invention of "IMPROVEMENTS IN MEANS
OR APPARATUS FOR EFFECTING THE CHOPPING OR SEPARATION OF ANIMAL AND
VEGETABLE SUBSTANCES."
Sealed the 3rd May 1864, and dated the 13th November 1863.
PROVISIONAL SPECIFICATION left by the said William Francis Dearlove
at the Office of the Commissioners of Patents, with his Petition, on the
13th November 1863.
I, WILLIAM FRANCIS DEARLOVE, of 263, Goswell Road, in the County of
Middlesex, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MEANS OR APPARATUS FOR EFFECTING THE CHOPPING OR SEPARATION OF
ANIMAL AND VEGETABLE SUBSTANCES," to be as follows:-
To a base plate or board I apply an axis, from which extend, somewhat
radially, a pair of bars supporting at their outer ends a segmental plate which
is capable of moving with the axis concentrically upon a stationary plate
standing up from the base plate or board. The cutting blade is applied with
its cutting edge towards the base plate or board, and so as to be capable of
motion between the pair of bars referred to, one end of such blade turning
upon a pin carried by the axis from the board or plate, whilst the other end
thereof is formed with a handle to give motion to it. By these means the
blade has a compound motion with its edge to and from the base plate or

page_text: board, as well as radially on the axis carried by such plate or board, to chop
or separate any matters placed on the plate or board. The pair of bars
between which the blade moves act as clearers, whilst the concentric plates
serve to prevent the matters under operation from escaping in that direction.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Francis Dearlove in the Great Seal Patent
Office on the 13th May 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
FRANCIS DEARLOVE, of 263, Goswell Road, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of November, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Francis Dearlove, Her special licence that I, the said
William Francis Dearlove, my executors, administrators, and assigns, or such
others as 1, the said William Francis Dearlove, 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 MEANS OR APPARATUS FOR EFFECTING THE CHOP-
PING OR SEPARATION OF AMIMAL AND VEGETABLE SUBSTANCES," upon the condition
(amongst others) that I, the said William Francis Dearlove, 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 William Francis Dearlove, 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: -
To a base plate or board I apply an axis, from which extend, somewhat
radially, a pair of bars supporting at their outer ends a segmental plate which
is capable of moving with the axis concentrically upon a stationary plate

page_text: standing up from the base plate or board. The cutting blade is applied with
its cutting edge towards the base plate or board, and so as to be capable of
motion between the pair of bars referred to, one end of such blade turning
upon a pin carried by the axis from the board or plate, whilst the other end
thereof is formed with a handle to give motion to it. By these means the
blade has a compound motion with its edge to and from the base plate or
board, as well as radially on the axis carried by such plate or board, to chop
or separate any matters placed on the plate or board. The pair of bars
between which the blade moves act as clearers, whilst the concentric plates
serve to prevent the matters under operation from escaping in that direction.
But that my Invention may be better understood, I will, by the aid of the
accompanying Drawing, proceed more fully to describe the same.

But that my Invention may be better understood, I will, by the aid of the
accompanying Drawing, proceed more fully to describe the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shows a plan view, and Figure 2 an edge view, of apparatus
according to my improvements; Figure 3 is a section through the same; and
Figures 4, 5, 6, and 7, show parts separately.
a is the base plate or board upon which the substances to be chopped or
separated are placed. To this board or plate a is applied the socket 6 which
receives the axis c from which extends radially the pair of bars d, d, to which
is affixed the segmental plate e, which is thereby capable of moving with the
axis c in the socket b. To the board a is also affixed a stationary segmental
plate f, upon which the plate e moves. g is the cutter, and g¹ is the cutting
edge thereof; one end of this blade g is formed with a handle g, and the other
to pass into an opening formed for it in the axis c, where it is retained by the
ping, so that by raising and depressing the blade g by its handle g' it will
turn upon the pin g³; and in order that the blade 9, when it is pressed on to
chop or separate the matters under operation, may be capable of slight hori-
zontal motion towards the axis c, the opening in the end of the blade 9 for the
ping is elongated, and the end of the blade is acted upon by the spring h.
In operating to chop or cut animal or vegetable substances the operator will,
in addition to the up-and-down motion to the blade g, also cause that blade to
traverse over the surface of the table a round the axis c, so as to progressively
chop or cut all the matters placed thereon. The bars d, d, serve to clear the
blade g, each time of its being raised, of any matters adhering thereto. a' is
a ledge which serves to prevent the substances being chopped or separated
from falling off the board at that part.
Having thus described my said Invention, and means which I adopt in
carrying the same into effect, I would have it understood that I do not confine

page_text: myself to the precise details shown and described, as these may be varied;.
but what I do claim is the adaptation or combination of means or apparatus
for chopping or separating animal and vegetable substances, substantially as
described. .
In witness whereof, I, the said William Francis Dearlove, have hereunto:
set my hand, and seal, this Twelfth day of May, in the year of our
Lord One thousand eight hundred and sixty-four.
WILLIAM FRANCIS DEARLOVE. (L.S.)
