Improvements in Cherry Stoners.
I, JOHN WILSON BROWN Junior of Frank Street near Green Street Germantown
in the County of Philadelphia State of Pennsylvania one of the United States of
America Mechanical Engineer do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The object of my invention is to so construct a cherry stoner that it can be cheaply
manufactured and can be readily operated and cleaned without being dismantled.
This object I attain in the following manner, reference being had to the accompanying
drawing; in which :-
Figure 1, is a perspective view of my improved cherry stoner;
Figure 2 is a section on the line 1-2 Figure 1.
Figure 3, is a section on the line 3-4 Figure 1 and
Figure 4 is a perspective view of the plunger.
A is the standard which is clamped to a table by the screw clamp a the said
standard being so curved that it will overhang a dish or other receptacle placed
under it.
Formed in the standard is the chute a¹ for the stones that are removed from the
cherries and above the chute is a plate a² to which is attached the hopper section B.
A plate of this hopper section is adapted to fit over the plate a², and, this
The plate is
plate has an opening for the passage of the cherry stones.
dished towards this opening, as shewn in the drawings, forming a pocket for
the cherry to be stoned, and clamped between the two plates is a washer c of rubber
or other flexible material, this washer is suitably cut so that with pressure the
stones will pass through the washer into the chute a¹ and be delivered into a
suitable vessel. The washer, however, is stiff enough to prevent the cherry itself
from passing through the washer.
The cherry is discharged to one side of the machine by an arm d on a disc D
carried by a shaft D' mounted in a bearing A' on the standard A, and this shaft is
provided with a handle d' by which it is turned, so that at each rotation of the
shaft a cherry will be stoned and will be thrown into a suitable receptacle at the
side by the arm.
Adapted to slide in an upright B¹ projecting from the hopper portion B is a
plunger E having a rib e adapted to a groove in the upright B'. A transverse slot e¹
is formed in this plunger, and adapted to the slot is a pin d² on the disc D, so that
as the disc is rotated the plunger reciprocates in a vertical plane. The lower
portion of the plunger is cruciform in shape and the outer edges of the ribs
terminate in points forming a pocket for the stone.
The mouth of the hopper B is so formed that one cherry at a time will be fed
to the pocket, and the parts are so timed that the plunger passes through the
cherry and forces the stone through the washer into the chute a¹ while the arm d
is elevated, the arm passing across the surface of the plate 6 when the plunger is
elevated, and as soon as the arm removes the stoned cherry another cherry takes its
place in the pocket under the plunger.
It will be noticed that the standard A and the bearing A' are made in a single
casting in the present instance, and the hopper B is made in two parts, the
division line being through the centre of the hopper and the centre of the plate b
and the two parts of the hopper are secured together by rivets or screws i and the
hopper section is secured to the standard by screws i¹.

page_text: The plunger is held in position between the disc D and the upright B', thus it
will be seen that the parts can be readily made without using elaborate moulds, and
can be put together with very little finishing.
The moving parts are all exposed so that the machine does not have to be taken
apart to be cleaned.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination in a cherry stoner, of the standard, the hopper section secured
thereto, a flexible washer, between the standard and the hopper section, a vertical
reciprocating ejecting plunger mounted above the washer, and adapted to pass
"therethrough, the said plunger being adapted to guides in the hopper section, a
shaft mounted in the standard and connected to the plunger so as to give it the
vertical reciprocating motion required and a discharging arm carried by the shaft,
substantially as hereinbefore described.
2. The combination of the standard, hopper section mounted thereon, a plate b
forming part of the hopper section having an opening, a yielding support,under the
said opening, a vertically reciprocating plunger mounted in the hopper section, a
shaft mounted in the standard, a disc on the said shaft connected to the plunger,
and an arm on the said disc for removing the stoned cherry from the machine
substantially as hereinbefore described.
3. The combination of the standard having a discharge chute therein, and a
supporting plate, a hopper section having an extension or plate secured to the
plate of the standard a flexible support for the cherry to be stoned, a vertical
reciprocating plunger having its lower portion cruciform in shape, and having a rib
adapted to a slot in the hopper portion and a transverse slot, a shaft mounted in
the standard, a disc mounted on the said shaft, a pin on the said disc adapted to the:
transverse slot, and through which the vertical reciprocating motion is imparted to
the plunger, an arm fixed to said disc and adapted to remove the stoned cherry
from the machine as the shaft is rotated substantially as herein before described.
4. The arrangement and combination of parts constituting the cherry stoner
substantially as hereinbefore described and illustrated by the accompanying drawings.
.Dated this 5th day of June 1894.
