Improvements in or relating to Raisin or Fruit Seeders and the like.
A communication from FRANK HOWARD CHASE, of 51, South Jefferson Street, in
the City of Chicago, in the County of Cook, and State of Illinois, United
States of America, Machinist.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
The present invention relates in part to the means for feeding material, to be
subsequently acted upon, at a regulated rate; as, for instance, for feeding raisins to
a seeding device, in part to the construction of a receiver, by which the material
to be treated is acted upon or broken up, in part to the means for ejecting the
material from the receiver, and in part to the general construction and arrangement
of the several parts of the machine.
The invention will be described as applied to a raisin or fruit seeder.
According to this invention the base or main portion of the frame of the
machine consists of a centrally disposed web below which are downwardly diverg-
ing webs, which in vertical section present the form of an inverted V, these webs
being bound by flanges surrounded by a rectangular frame. Upon this base are
mounted journal boxes in which is journalled the shaft of the pulp receiver. This
pulp receiver takes the form of a cylinder armed with numerous radial pins dis-
posed at such distance apart that the seeds of the fruit cannot enter between them.
The pulp receiver is preferably constructed of a backing which may take the form
of a cylinder or brass or other suitable material, having a number of grooves dis-
posed radially and longitudinally, a toothed strip fitting in each of the grooves
and a number of sector shaped plates secured to the ends of the cylinder and having
ribs which engage in corresponding notches in the ends of the strips the ends of
the cylinder being also notched between the grooves to receive the ribs. The
toothed strips are made of sheet metal and the teeth are bevelled on one side so
that when the several strips are assembled and secured in place, the front faces
of the teeth will have a backward rake or pitch, to facilitate ejecting the pulp.
In the space between each row of pins and the next is disposed a pulp ejector
which preferably consists of a piece of metal one end of which is curved to
conform to the pulp receiver cylinder which it straddles and the other end of which
is curved to conform to a shaft which it straddles and which is supported by a
pair of hangers mounted upon the pulp receiver shaft. The working surfaces of
the ejectors are curved and preferably each of the ejectors has two working sur-
faces so that should one become disabled or broken the ejector may be reversed and

page_text: the other used. In order to maintain the pulp ejectors in proper position, the
hangers are provided with shoulders which engage a portion of the frame.
The impaling device preferably consists of an elastic roller mounted upon a
shaft which is journalled in boxes slidably mounted upon the frame, set screws
being provided for adjusting the position of the impaling roll with relation to the
pulp receiver, and locking screws for securing the boxes in place when adjusted.
For the purpose of dislodging the seeds from the surface of the pulp receiver a
blade or scraper is secured to an extension of the central web of the main portion
of the frame and this blade is adjustable by means of set screws occupying
threaded openings in lugs on the frame, clamping bolts and nuts being provided
for locking the scraper in place when once adjusted.
The hopper into which the fruit to be seeded is dumped may be provided with a
false bottom consisting of two flexible sheets or plates which are preferably made
of sheet metal. At their lower margins these flexible plates rest upon a pair of
feed rolls one of which is journalled eccentrically and to its shaft is secured a
pinion meshing with a larger pinion mounted upon the pulp-receiver shaft. Upon
the shaft of this feed roll is secured also a pinion which meshes with the corre-
sponding pinion secured to the shaft of the other feed roll.
By this means the shaft of the second feed roll derives its movement from the
shaft of the pulp receiver, and the shaft of the first feed roll. The feed rolls are
rotated in such direction that their adjusting faces always move upward. Both
of the feed rolls are journalled eccentrically and they are so disposed with relation
to their respective axes of motion that the longest (or any other given) radii of
both project in the same direction from their respective axes of motion. As a
result of this disposition of the feed rolls the distance apart of their adjacent
faces remain constant throughout their operation, but the position of the space
between them is being constantly shifted in a horizontal direction. The flexible
sheets forming the false bottom of the hopper partake of the movement of the
eccentrically mounted feed rolls and as a result of this the fruit is considerably
agitated. Actual practice has demonstrated that the liability of choking is entirely
overcome and the feeding of the fruit to the seeding devices is quite as uniform
as it need be.
In order to adjust and regulate the width of the space between the feed rolls,
for the purpose of handling material of different sizes one of the feed rolls may be
made adjustable relatively to the other. This may be accomplished by journalling
the shaft of the adjustable roll in boxes which are sildably supported by guides
and by providing an adjusting screw which projects through a web on the hopper
and receives upon opposite sides of the web, respectively a pair of lock nuts.
In order that access may be had to the seeding devices for the purpose of
removing them or repairing them or cleaning them, the hopper and the feeding
devices may be supported by a frame section hinged to the main frame so that
the entire frame section and the devices carried by it may be swung or moved
from their position over the feeding devices leaving the latter exposed. When so
exposed either the impaling roll or the pulp receiver may be removed.
In the foregoing description I have particularly described the invention as relat-
ing to improvements in raisin seeders, but manifestly they may be embodied in
machines to be used for seeding fruit other than raisins, and in other machines of
similar nature, in which the operations of feeding, crushing and separation of parts
are involved.

the City of Chicago, in the County of Cook, and State of Illinois, United
States of America, Machinist.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The present invention relates in part to the means for feeding material, to be
subsequently acted upon, at a regulated rate; as, for instance, for feeding raisins to
a seeding device, in part to the construction of a receiver by which the material
to be treated is acted upon or broken up, in part to the means for ejecting the
pulp from the pulp receiver, and in part to the general construction and arrange-
ment of the several parts of the machine.

In the accompanying drawings
Figure 1 is a side elevation of a raisin seeder embodying the invention.
Figure 2 is a vertical section thereof on the line 2-2, Figure 1.
Figure 3 is an end elevation, on a larger scale, of the pulp receiver, with a
portion broken away.
Figure 4 is a section thereof on the line 44, Figure 3.
Figure 5 is an end view, on a still larger scale, of one of the toothed strips of
the pulp receiver.
Figure 6 is a side elevation of a fragment thereof.
A represents the base or main portion of the frame of the machine. It con-
sists of a centrally disposed web a, below which are downwardly diverging webs a¹,
which in vertical section present the form of an inverted V, these webs being
bound by flanges all, and the latter being surrounded by a rectangular frame a².
Upon this base are mounted journal boxes B in which is journalled the shaft C
of the pulp receiver D. This pulp receiver takes the form of a cylinder armed
with numerous radial pins disposed at such distance apart that the seeds of the
fruit cannot enter between them. As shown more clearly in Figures 3 to 6,
inclusive, the pulp receiver is constructed of a backing A', which preferably takes
the form of a cylinder of brass or other suitable material, having a number of
grooves disposed radially and longitudinally, a toothed strip B₁ fitting in each of
the grooves, and a number of sector shaped plates C2 secured to the ends of the
cylinder and having ribs c which engage corresponding notches in the ends of the
strips, the ends of the cylinder being also notched, between the grooves, to receive
the ribs. The toothed strips are made of sheet metal and the teeth are bevelled
on one side, so that when the several strips are assembled and secured in place, the
front faces of the teeth will have a backward rake, or pitch, to facilitate ejecting
the pulp. These strips arranged parallel with each other, have teeth of sufficient
length to leave, between them, when the strips are assembled, interstices of suffi-
cient depth to receive the pulp, while, at the same time, they are insufficient in
width to admit seeds.
In the space between each row of pins and the next is disposed a pulp ejector E,
which preferably consists of a piece of metal one end of which is curved to con-
form to the cylinder which it straddles and the other end of which is curved to

page_text: conform to a shaft F which it straddles and which is supported by a pair of
hangers G mounted upon the shaft C. The working surfaces of the ejectors are
curved as shown at o, and preferably each of the ejectors has two working sur-
faces, so that should one become disabled or broken the ejector may be reversed
and the other used.
H is the impaling device. Preferably, it consists of an elastic roller mounted
upon a shaft which is journalled in boxes I, slidably mounted upon the frame,
set screws J being provided for adjusting the position of the impaling-roll with
relation to the pulp receiver, and locking screws being provided for securing the
boxes in place when adjusted. As indicated in Figure 2 these locking screws pass
through slots in the boxes and are tapped into the frame of the machine..
For the purpose of dislodging the seeds from the surface of the pulp receiver
a blade or scraper L is secured to an extension of the web a, and this blade is
adjustable by means of set screws 7 occupying the threaded openings in lugs on
the frame, clamping bolts and nuts being provided for locking the scraper in
place when once adjusted.
The
M represents the hopper into which the fruit to be seeded is dumped.
hopper is provided with a false bottom consisting of two flexible sheets or plates m,
which are preferably made of sheet metal. At their lower margins these flexible
plates rest upon a pair of feed rolls, NN1, respectively. The feed roll N is
journalled eccentrically and to its shaft is secured a pinion n meshing with a
larger pinion C₁ which latter is mounted upon the shaft C. Upon the shaft of this
feed roll is secured also a pinion n¹ which meshes with the corresponding pinion n¹¹
secured to the shaft of the feed roll N¹. By this means the shaft of the feed
roll N¹ derives its movement from the shaft of the pulp receiver, and the shaft
of the feed roll N. The feed rolls are rotated in such direction that their adjust-
ing faces always move upward. Both of the feed rolls are journalled eccentrically
and they are so disposed with relation to their respective axes of motion that the
longest (or any other given) radii of both project in the same direction from their
respective axes of motion. As a result of this disposition of the feed rolls the dis-
tance apart of their adjacent faces remains constant throughout their operation,
but the position of the space between them is being constantly shifted in a
horizontal direction.
The flexible sheets m, forming the false bottom of the hopper partake of the
movement of the eccentrically mounted feed rolls and as a result of this the fruit
is considerably agitated. Actual practice has demonstrated that the liability of
choking is entirely overcome and the feeding of the fruit to the sceding devices
is quite as uniform as it need be.
In order to adjust and regulate the width of the space between the feed rolls,
for the purpose of handling material of different sizes one of the feed rolls is
made adjustable relatively to the other. This is accomplished by journalling the
shaft of the adjustable roll in boxes which are slidably supported by guides o
and by providing an adjusting screw P which projects through a web on the hopper
and receives upon opposite sides of the web, respectively, a pair of lock nuts
P.
In order that access may be had to the seeding devices for the purpose of
removing them or repairing them or cleaning them, the hopper and the feeding
devices are supported by a frame section Q which is hinged to the main frame A
at
so that the entire frame section and the devices carried by it may be swung
or moved from their position over the feeding devices leaving the latter exposed.
When so exposed either the impaling roll H or the pulp receiver D may be
removed. By reason of the fact that the ejectors E are supported by the shaft F
which in turn is supported by the hangers G mounted upon the shaft of the pulp
receiver, when the pulp receiver is removed all of the pulp ejectors are removed
with it. In order to maintain the pulp ejectors in proper positions, i.e. the posi-
tions shown in the drawing, the hangers Fare provided with shoulders f which
engage the portion a² of the frame.

page_text: In the foregoing description the invention is particularly described as relating
to improvements in raisin seeders, but manifestly they may be embodied in
machines to be used for seeding fruit other than. raisins, and in other machines
of similar nature, in which the operations of feeding, crushing and separation of
parts are indicated.
Having now particularly described and ascertained the nature of the said
invention as communicated to me by my foreign correspondent and in what
manner the same is to be performed, I declare that what I claim is;-
-
1. A fruit seeding machine having a pulp receiver made up of a revoluble sup-
port, a number of straight toothed strips of metal, means for removably attaching
the toothed strips to the support, side by side, and parallel with the axis of
rotation so that the teeth of the several strips shall fall in circumferential rows,
the teeth being of sufficient length to provide between them interstices of sufficient
depth to receive the pulp, said interstices being insufficient to admit the seeds,
in combination with an elastic device for impaling the fruit upon the teeth of the
pulp receiver, and ejectors occupying the spaces between the circumferential rows
of teeth, substantially as set forth.
2. In a raisin seeder, the combination of a cylinder provided with grooves dis-
posed longitudinally, metallic strips occupying the grooves and having teeth pre-
sented outward, means for confining the strips in the grooves so that the teeth
fall in circumferential rows, said teeth being of sufficient length to provide between
them interstices of sufficient depth to receive the pulp, said interstices being
insufficient to admit the seeds, means for impaling the pulp upon the teeth, and
means occupying the spaces between the circumferential rows of teeth for ejecting
the pulp, substantially as set forth.
3. In a feeding device for raisin seeders and similar machines, the combination
of a pair of eccentrically journalled feed rolls disposed side by side but out of
contact with each other, means for revolving the rolls so that their adjacent faces
move upward, and means for preventing the material from passing outside of the
rolls, substantially as set forth.
4. In a feeding device for raisin seeders and similar machines, the combination
of a pair of eccentrically journalled feed rolls disposed side by side but out of
contact with each other, means for revolving them so that their meeting faces
move upward, and a hopper having a bottom formed in movable sections bearing
upon the feed rolls so as to partake of their movement, substantially as set forth.
5. In a feeding device for raisin seeders and similar machines, the combination
of a pair of eccentrically journalled feed rolls disposed side by side but out of
contact with each other, and with their longest radii in similar positions with
respect to the respective axes of rotation, means for revolving them so that their
meeting faces move upward, and a hopper having a bottom formed of sheets of
flexible material resting upon the feed rolls so as to partake of their movement
and prevent the material from passing outside of them substantially as set forth.
6. In a raisin seeder, the combination with a pulp receiver consisting of a
cylinder provided with circumferential rows of teeth, and means for impaling the
pulp thereon, of ejector blades occupying the spaces between the circumferential
rows of teeth, and means for supporting the ejector blades, each of the ejector
blades being notched or cut away at one end to straddle the cylinder at the bottom
of the groove and notched at the other end to straddle its support, substantially
as set forth.
7. In a raisin seeder, the combination with a pulp receiver consisting of a
cylinder having circumferential grooves, of pulp ejectors occupying the grooves, a
shaft by which the pulp ejectors are supported, said ejectors being notched at one
end to straddle the shaft, and at the other end to straddle the cylinder and hangers
supporting the shaft and in turn supported by the shaft of the cylinder, substan--
tially as set forth.
