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 
circular cutter.

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.
