Year: 1856

page_text: LETTERS PATENT to David H. Whittemore, of Worcester, Massachusetts,
in the United States of America, for the Invention of "AN IMPROVED
MACHINE FOR PARING. SLICING. AND CORING FRUIT OR VEGETABLES."
Sealed the 21st April 1857, and dated the 29th October 1856.
PROVISIONAL SPECIFICATION left by the said David H. Whittemore at
the Office of the Commissioners of Patents, with his Petition, on the
29th October 1856.
I, DAVID H. WHITTEMORE, of Worcester, Massachusetts, in the United
States of America, do hereby declare the nature of the said Invention for
"AN IMPROVED MACHINE FOR PARING, SLICING, AND CORING FRUIT OR VEGETABLES,"
to be as follows:-
It consists in the mode of paring, slicing, and coring, by means of knives
suitable for each purpose, so arranged & operated that the paring precedes
the slicing process, and the slicing and coring knives are acting upon the
pared portion simultaneously with the paring knife on the remainder. By
removing the slicing and coring knife, which may be considered as one knife,
the paring only is effected.
The effect is produced by attaching upon a stand, sliding upon a rod on
bearings on the main stand, the paring knife and the slicing & coring knife,

page_text: and connecting this sliding stand by a guide to the spirally-grooved shaft, to
which the fork and the crank are attached. The end of the guide working in
the spiral groove is drawn towards the crank end of the shaft, and draws with
it the sliding stand and the knives attached thereto, as far as required. The
paring knife is supported on each side in a wedged-shaped holder, that ter-
minates in a rod. This holder is so adjusted in a socket that it may partly turn,
& by a spring shall also receive a certain pressure, so directed, that the knife
in contact with the apple may turn to accommodate itself to the surface
thereof as it proceeds. This socket, by suitable means, is pressed towards the
fork with sufficient force to keep the knife in proper position to pare the
apple, and by means of an arm coming in contact with a guide rod is pre-
vented being pressed too far, so that the knife would come in contact with the
fork. The slicing knife is a thin blade, that attached to the sliding stand
follows the same movement as the paring knife & cuts the matter into spiral
circles, which the coring knife on the end of the latter detaches from the
apple when cutting out the core.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by tho said David H. Whittemore in the Great Seal Patent Office on the
29th April 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
II. WHITTENORE, of Worcester, Massachusetts, in the United States of
America, send grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of October, in the year of our Lord
One thousand eight hundred and fifty-six, in the nineteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
David H. Whittemore, Her special licence that I, the said David II. Whitte-
more, my executors, administrators, and assigns, or such others as I, the said
David H. Whittemore, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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 IN-
PROVED MACHINE FOR PARING, SLICING, AND CORING FRUIT OR VEGETABLES," upon
the condition (amongst others) that I, the said David II. Whittemore, or my
executors or administrators, by an instrument in writing under my, or their,

page_text: 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 David H. Whittemore, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying Drawings, in which
Figure 1 represent a side elevation; Figure 2 gives a vertical, and Figure 3
an end view. Like parts are indicated by the same letters.
The Invention consists in the mode herein described and claimed, by which
the process of paring, slicing, and coring is effected in one successive operation
by knives suitable for each purpose.
The machine may be described as follows:-A is the main stand; B, B, are
the uprights on which it is supported in bearings the shaft C with its fork E
and crank F; D represents the spiral groove; and G, the guard, to confine
the end of the traveller II, attached to the sliding stand K. Through the
ears M, M, of this stand passes the rod J, supported at I and B, B, on which
the stand moves. O is a socket, supported on bearings N, N, as pivots; P is
spiral spring, giving pressure on the socket in a direction towards the fork;
R, an arm connected with the socket, and when resting upon the elevator S
prevents the socket from further turning, and the knife L from coming in
contact with the fork; T is the knifeholder, bifurcated at the upper end and
terminating in a rod at the other. The forks V, V, are grooved to receive the
knife, which is inserted diagonally and secured by a screw, with its edge
slightly projecting beyond the body of the holder leaving a throat below
through which the paring is to pass. The socket is constructed to receive the
end of the knifeholder and a spiral spring U. In the rod T is put a small
pin W, which holds it in the socket, and on which the spring U acts to
present the edge of the knife to the apple on commencing, the rod having a
circular or turning motion in the socket, so as to turn half round, or a little
more. X is the slicing knife with its lip, or the coring knife Y, attached by a
screw at N, and so adjusted as to clear the fork. The lip Y is at right angles
with X, and the lower edge of the first and the inner edge of X are sharpened
and form the cutting edges.
When the apple is placed on the fork, the end of the traveller is placed in
the spiral groove D, and there confined by the guard during the operation;
when the crank is turned, the stand K, to which the traveller is attached, is

page_text: drawn towards the fork, and the paring knife set, as represented, and pressed
by the spring P towards the apple, comes in contact with it, and begins to
pare near the centre. As it proceeds, the form of the apple causes the spring P
to yield, that the sockets may turn and swing the knife off so as to pass round
the apple. The spring U at the same time allows the rod T to turn, so as to
present the edge of the knife to the surface all the way round, the action of
the two springs accommodating the edge of the knife to the conformation
of the surface. The slicing knife following cuts the apple into a spiral slice
corresponding to the groove D, and the lip or coring knife cuts the same from
the core as fast as it is sliced. The operation being thus effected, the traveller
having passed beyond the control of the guard is taken out of the groove,
and with the stand K is turned and slid back on the rod J outside of the
guard to its first position. If paring is the only object the knife X is
removed.
Having thus described the nature of my Invention, and in what manner the
same is to be performed, what I claim under the above in part recited Letters
Patent is as follows:-
I claim the arrangement of the groove, slide, and paring knife, as above
described, or any other arrangement substantially the same.
I claim the knife X and its lip Y to cut the apple into a continuous spiral
slice from the core.
I claim paring, slicing, and coring simultaneously, substantially as
described.
In witness whereof, I have hereunto set my hand and seal, this Thirtieth
of January A.D. Eighteen hundred & fifty-seven.
Attest.
