UNITED STATES PATENT OFFICE.
ROBERT W. MITCHELL, OF SPRINGFIELD TOWNSHIP, HIGHLAND COUNTY,
OHIO. MACHINE FOR PARING, CORING, AND DIVIDING APPLES.
Specification of Letters Patent No. 686, dated April 13, 1838.
To all whom it may concern:
Be it known that I, Egbert W. Mitchell, of Springfield township,
Highland county, State of Ohio, have invented a Machine for
Paring, Coring, and Quartering Apples, which is described as
follows, reference being had to the annexed drawings of the same,
making part of this specification.
The nature of my invention consists in placing the apple on a
fork inserted into the end of a shaft, which shaft is turned by a
crank by hand while the operator holds with his other hand a
paring knife to the surface of the apple, said knife being turned
and accommodated to the shape of the apple as it is advanced by
the crank shaft, and when pared forcing it between knives which
core and quarter it, the center one for taking out the core being
circular and the others which quarter it being straight and
radiating from the surface of the circular knife, and when
quartered the pieces of apple falling upon an inclined board by
which they are conducted to a receiver while the core is driven
out at the end of the machine.
A, Fig. 1, represents a bench of suitable length, breadth, and
height to support the several parts of the machine. B, B
represent two upright pieces of timber mortised and tenoned into
the bench in a vertical position about 3 inches apart, between
which, near the top, is placed a hub, or round piece of wood c
perforated through the center with a circular aperture, through
which the shaft D passes. The shaft D is made a little less in
diameter than the aperture in the hub through which it passes,
except at the end where the handle is inserted, where it is
E represents the crank handle for turning the shaft. F, the fork
in the smaller end of the shaft upon which the apple is stuck.
The knife G, for paring the apple is made something like the
coopen's draw-knife and is fastened on the end of a stick H,
which is attached to the edge of the bench by a universal joint
to allow of its being turned about in any direction required.
About six inches from the upright B, B, is a vertical piece of
timber L mortised and tenoned into the bench, in which, near the
top of the same is made a round aperture M larger than the apple
to be pared and which passes through said aperture. To this piece
of timber and around the aperture inside is fastened a circular
curb. Around the curb is placed a circular ring O through which
pass screws P for securing and setting the knives. At the end of
the bench is a post I through which passes the center circular
cutter or tube K for cutting out the core, made funnel shaped,
and projecting horizontally from said post to the face of the
vertical piece of timber L the larger or discharging end being
next to the post. In the surface of the circular cutter or tube
at the smaller end are small cavities or depressions to admit
small projections or points at the ends of the knives Q, by which
they are held securely, the other ends of said knives containing
cavities to admit the ends of the thumb screws P passing through
the ring O for securing and regulating the knives. For quartering
the apples the four knives Q described are all that will be
necessary but should it be required to cut the apples in smaller
pieces more knives and screws will be required.
The knives are made in the manner represented at Fig. 2 having
ribs or points T for entering the cavities in ' the surface of
the circular cutter or tube before described. The other end
containing a cavity or depression for the point of the thumb
screw P used for securing and setting the knife. The knives
radiate from the outer surface of the circular knife or tube K to
the inner surface of the curb at equal distances apart.
Between the vertical piece of timber L and post I is a curved
casing E to catch the pieces of apple and conduct them to an
inclined spout S below which conducts them to a receiver.
Operation: Put the apple on the fork, take the stick containing
the paring knife in the left hand, the crank handle in the right.
The shaft being drawn back apply the knife to the end of the
apple near the core, turn the crank and the shaft and apple. At
the same time manage the knife so as to conform to the shape of
the apple until it is pared from one end to the other in a
continuous paring. The apple is then pushed against the cutters
and divided into parts which fall upon the inclined board and are
conducted to the receiver. The core is forced through the tube or
Fig. 3 represents the paring knife detached from the bench.
What I claim as my invention and which I desire to secure by
Letters Patent consists in—
The combination of the before described machine for paring with
the knife for dividing, and coring apples.
