rollers i, separate the edges h of the knives H,
so that they pass on opposite sides of the stone
of the fruit, and when the fruit has passed
farther down the said grooves close the knife-
5 edges h over the top of the stone, so that the
stone is detached and can fall through the open-
ing A' in the base-plate below the knives H.
The handle is then depressed, raising the guide-
plate and cap c, so that a second fruit can be
Io placed under the cap and upon the knives to
be operated upon as described. After the
stone has been dislodged, the edges h of the
knives H remain closed and cut through the
fruit above the stone with the edges g of the
15 blades G, so that the peach is divided in half
and stoned simultaneously. In such fruits as
apples the core is removed in the same man-
ner.
Having described my invention, what I
20 claim, and desire to secure by Letters Patent,
is-
1. In a fruit-cutter, the combination of the
pivoted knives having laterally-concaved fac-
ing sides and curved inward to the edges at
25 their upper ends, the arms extending from one
side of said knives near their lower end, and
the vertically-moving guide-plate provided
with the longitudinal guide-grooves parallel
at their upper and lower portions and curving
30 inward to meet at their centers, into which
grooves the ends of said arms enter for the pur-
pose of opening and closing said knives, sub-
stantially as and for the purpose specified.
2. In a fruit-cutter, the combination, with
35 the vertically-reciprocating follower-cap, of
the vertical flat knives having cutting-edges
at their upper ends, the concave knives H,
rounded inward at their upper ends to their
edges h, pivoted through their perforated earsupon pins standing inward from said vertical 40
knives, and one of which is provided with
transverse cutting-edges h", the arms I, stand-
ing from said knives, the anti-friction rollers
i on the ends of said arms, and the guide-plate
D, having its shank attached to arms standing 45
from the follower-cap, passing into the guide-
opening d in the base-plate of the machine,
and provided with the guide-grooves E, into
which the anti-friction rollers i enter, substan-
tially as specified. 50
3. The herein-described fruit-cutting ma-
chine, comprising the base-plate A, provided
with the aperture A' and guide-opening d, the
standard B, the sleeve b, uniting arms stand-
ing horizontally from the top of the standard, 55
the vertical rack-bar, the follower-cap on the
lower end of said rack-bar, the segmental rack
F, having the handle and meshing with the
rack-bar, the guide-plate D, having its shank
adjustably attached to arms extending from 60
the follower-cap by means of a pin and a series
of adj usting-openings, and provided in its outer
face with the guide-grooves E, the vertical flat
knives G, secured to the base-plate and hav-
ing rounded cutting-edges g at their upper 65
ends, the concave knives H, pivoted through
perforated ears to pins standing from the in-
ner edges of the vertical flat knives, the arms
I, standing from the concave knives, and the
anti friction rollers i on the ends of said arms o
entering the guide-grooves E, substantially as
specified.
In testimony whereof I affix my signature in
presence of two witnesses.
