Improvements in Raisin Seeding Machines.
I, FRANK HOWARD CHASE, of 51 South Jefferson Street Chicago in the
County of Cook and State of Illinois, United States of America, Machinist, 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 present invention relates to that class of seeders which have a circumferen-
tially grooved cylinder upon which the pulp is impaled by some suitable device,
such as a soft roller, and strippers for stripping the pulp from the cylinder after
the seeds have been disposed of, and it consists in certain novel features in the
construction of the strippers, hereinafter described.
Heretofore the pulp-strippers have been constructed of a comb-like piece of
sheet metal secured to the frame so that its teeth project into the grooves of the
cylinder, and the object of the present invention is to provide strippers that
possess advantages that strippers thus constructed do not.
In order that the invention may be fully understood I will describe the same
with reference to the accompanying drawing, in which—
Figure 1 is a side elevation of a raisin seeder embodying the invention, a portion
of the cylinder being broken away and,
Figure 2 is a section thereof on the line 2-2, looking in the direction of the
arrow.
A represents the frame which may be of any suitable construction and is
preferably provided with means for clamping it to a table and surmounted by a
hopper B. Beneath this hopper the frame is provided with a tubular extension a
which affords a bearing for the crank-shaft C. A portion cof, this shaft is of
reduced diameter to form a shoulder c¹ and on this reduced portion fit a number of
discs D and washers E alternating with each other, a nut F being fitted to the end
of the shaft for clamping the discs and washers against each other and against the
shoulder of the shaft, with such firmness that they will not be moved independently
of each other by any strain that they will be subjected to in use.
The discs and
washers thus become, in effect and to all intents and purposes, a cylinder having
circumferential grooves, against which the raisins are pressed by the soft roller G,
which is mounted to turn freely upon a shaft H suitably secured to the frame.
When the cylinder is turned in the direction of the arrow, raisins fed into the
hopper will be carried between the cylinder and roller. The latter is sufficiently
soft to yield to the pressure of the seeds and at the same time sufficiently firm to
impale the pulp upon the cylinder, forcing much of it into the grooves. Below the
soft roller is located the seed stripper I, and beyond this in the direction of
rotation, are located the pulp strippers which preferably consist of a number of
plates located in the grooves and suspended from the axis of the cylinder.
These strippers are of less thickness than the washers E, and each is provided with
a perforation for receiving one of said washers. It is sufficiently long to project
beyond the periphery of the cylinder and bear against a stop A¹, by which it is
prevented from turning with the cylinder. As the pulp comes against the edges of
these strippers they are carried to the positions shown in the drawing, coming
against the stop, and when in this position they will strip the pulp from the
cylinder and permit it to fall. Strippers thus constructed are simple, easily made,
can not possibly be broken by any strain that can be put upon them by ordinary
usage, and enable the parts to be cleaned with great facility.

page_text: 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. In a raisin seeder, the combination with a suitable frame, a pulp cylinder
having portions of reduced diameter, means for impaling the pulp upon the
cylinder and means for turning the cylinder, of a number of strippers suspended
from the reduced portions of the cylinder and projecting beyond the periphery of
the cylinder, substantially as set forth.
2. In a raisin seeder the combination with a frame a pulp-cylinder having a
number of circumferential grooves, and means for turning the cylinder, of a number
of strippers suspended in the grooves, from the axis of the cylinder, and projecting
beyond the periphery of the cylinder, and means for preventing the strippers from
turning with the cylinder, substantially as set forth.
3. In a raisin seeder, the combination with a frame and a shaft of a number of
discs carried by the shaft, a number of washers alternating with the disks, a number
of strippers loosely suspended from the washers and projecting beyond the peripheries
of the disks, and a stop for preventing the strippers from turning with the disks,
substantially as set forth.
4. In a raisin seeder, the combination of a frame, a shaft journalled therein, and
having a shoulder, a number of disks and washers arranged on the shaft alternately,
so as to form a circumferentially grooved cylinder, a nut turned on to the shaft and
clamping the disks and washers against each other and against the shoulder of the
shaft, a number of strippers perforated to fit loosely over the washers and projecting
beyond the periphery of the cylinder, and a stop for preventing the strippers from
turning with the cylinder, substantially as set forth.
