COMPLETE SPECIFICATION (AMENDED).
Improvements in Raisin-seeders.
I, WILLIAM JOHNSON, of Hull, in the County of Plymouth, State of Massa-
chusetts, United States of America, Carpenter, 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:-
My invention relates especially to a device for extracting the seeds from raisins
and the like; and it consists in certain novel features hereinafter fully set forth
and claimed, the object being to produce a simple, cheap and effective device of
this character.
In the accompanying drawing forming part of this Specification,
Figure 1 is a side elevation of my improved raisin-seeder;
Figure 2 a rear elevation of the same partly broken away;
Figure 3 a transverse section on the line, a, a, Figure 1; and
Figure 4 an underside plan view showing the scraper.
Like letters and figures of reference indicate corresponding parts in the different
figures of the drawing.
The nature and operation of the improvements will be readily understood by all
conversant with such matters from the following explanation.
A represents the body of the raisin-seeder which comprises a standard provided
with an angle-clamping arm b through which passes a thumb-screw d to secure it
in position on a support B.
A stub-shaft is journalled in the top of the standard and is actuated by a
crank-handle The end of the shaft is threaded and a nut h for taking up wear
is screwed thereon.
On the said shaft is a perforating wheel D, which comprises a series of
peripherally toothed discs separated by washers i as best shown in Figures 3 and 4.
Opening over the top of the wheel and secured to the standard is a hopper H.
The standard has a curved segmental guard; formed integrally therewith and
covering the rear portion of the wheel 1) and to the lower end of said guard a
comb kis secured. This comb has a series of teeth m formed of spring metal
which enter between the discs forming the wheel D) and have their free ends
engaging with the washers i thus forming a scraper for the wheel.
At the side of the wheel opposite the guard ; is a chute p secured to the
standard. The standard is slotted horizontally at q, and in the said slot is held a
shaft r which is adjustable laterally therein. On this shaft is journalled a rubber
presser-wheel engaging with the teeth of the perforating wheel D.
In the use of my improved device, the raisins to be seeded are thrown into the
hopper H and the crank 7 rotated.
The wheel D moves in the direction of the arrow t in Figure 1. and carries the

page_text: raisins against the presser-wheel t which is moved in the opposite direction by
friction.
The raisins are thereby forced aginst the teeth which penetrate and cut them
in such a manner that the presser-wheel will force the meat and skin of the raisins
in between the discs forming the wheel D), the stones or seeds being carried along
by the teeth on the outside thereof.
The chute p has its upper edge at z scraping the periphery of the wheel and the
stones or seeds are thereby removed and carried down the chute. The meat and
skin of the raisins are extracted by the curved teeth m of the comb k and are
dropped onto the support B or any suitable receptacle.
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:-
:-
1st. In a raisin-seeder, a perforating-wheel constructed of a series of toothed
discs, in combination with a flexible presser-wheel engaging with the periphery of
the perforating-wheel.
2nd. In a raisin-seeder, the rotary perforating wheel I mounted on a standard,
in combination with the hopper and the adjustable rubber presser-wheel t on the
said standard, constructed, arranged and operating substantially as described.
3rd. In a raisin-seeder, the combination of the standard with the perforating
wheel I mounted thereon, the flexible presser-wheel engaging with the periphery
of the said wheel, the scraping-chute and the comb k, having teeth projecting into
the periphery of the said perforating wheel, substantially as described.
Dated this 12th day of March 1895.
