This invention relates to nut branding ma
chines of the general type disclosed in applica
tion Serial No. 117,232 filed December 22, 1936,
by William P. Bullard and Oswell L. Williams
5 now issued as Patent No. 2,101,775, dated Decem
ber '7, 1937, and more particularly thefinvention
aims to provide an improvement in the marking
mechanism for such machines.
An important feature of the invention is to
l0 provide in a nut branding machine a self-ad
justable rocker trough designed to compensate

for lack of regularity in the shapes of the nuts
as they are rolled over the printing die by the
feed Wheel. In its preferred form the trough

one end larger than the other, is rolled along the
trough, the trough will tilt about a longitudinal
20 axis as well as yield downwardly to allow the nut
to be evenly pressed into engagement with the
printing die which projects into the open slot.
'I‘he invention has as another object to pro
vide in a nut branding machine a rotary print
ing member carrying a plurality of printing dies
adapted to be actuated to successively bring dif
ferent dies into printing position beneath the
rocker trough and an inking roller operatively
connected to and driven by the rotary printing
-member. In the preferred construction of our
invention a transfer spool is interposed between
the rotary printing member and the inking roller
for transferring ink from the inking roller to the
printing dies.
Another object of our invention is to provide
in a. nut branding machine of the above character
one or more cleaning cylinders positively driven
end view;

Figure 6 is a longitudinal cross~sectional View
of the punched perforations upon the inking’i'oll
er for feeding ink to the pad wrapped upon its
circumference; and
Figure 8 is a cross-sectional view of a protec
tive cup telescoped over the inking roller after
the latter has been removed from the machine.
Referring to Fig. 1, the nut branding machine,
generally stated, comprises an open framework 25
l supporting in elevated position a hopper 2 for
receiving nuts in bulk, from which they are dis
charged into a downwardly-inclined, recipro
cable conveyor chute 3. The upper end of 30
the conveyor chute extends into the bottom of the
hopper and the nuts discharge from the hopper
into the conveyor through an opening controlled
by a vertically slidable,.gravity-operated gatef4
mounted upon anti-friction bearings in a guide
way
5.
'
_
Y
The lower end of vthe chutey is slidably sup
ported in a box-like housing 6, and also mounted f
from the rotary printing member to wipe vthe
superñuous film of ink from the printing dies within. this housing adjacent the lower end of
40 between their successive printing operations.
' the chute is an adjustable throat 'l (Fig. 3) for
A further object of the invention is to provide receiving the nuts individually from the chute.
A stop plate 8 supported upon a yieldable rubber
a fountain type of inking roller which is of rela
pad Sa closes an end of the throat 'l and serves
tively simple ancl improved construction for pre
_ venting slippage of the inking pad which is wound
" thereon and for insuring an elîicient feed of the
ink to the pad; This inking roller is adapted to
be readily removed from the machine and nested
within a cup to seal the same against the at
mosphere or for convenience in shipping.
Other objects and advantages will be apparent
from the following detailed description of a pre
ferred form of the invention, reference being had
to the annexed drawings in which:
Figure 1 is a view in side elevation of a nut
as a stop for the nuts moving down the conveyor
into the throat. The stop plate is slidably dis
posed between the two interned flanges 9a of a
pair of angle irons 9 supported by and extending
5
upwardly from a cross plate IB arranged cross
wise of the machine frame.
The rubber pad
which is adhesively secured to the bottom of the u
stop plate rests upon the upper edge of the cross
plate lli and the stop plate is maintained in up
right position by a plate Ii’ extending'betweenV
and attached to the inner faces _of the flanges Sa
of the upright angle irons 9 and a second plate 55
2
2,109,380
I2 fastened to the outer faces of these flanges,
the arrangement being such that the stop plate
projects a short distance above the plates Il
and I2.
y
Vertically slidable within the throat is an ele
vating bar I3 having its upper end formed with
a concaved bevel I3a approximating the rounded
outer surface of a nut and having its lower end
engaging the periphery of a spiral cam disk I4.
10 The cam disk is keyed upon a shaft 28 rotatable
in the machine frame. This elevating bar is
gradually raised by the rotating cam disk with
a slight jarring action by reason of the notches
I4a upon the periphery of the cam disk so as to
and upon this pin is rotatably supported a final
cleaning cylinder 21 provided with a circumfer
ential pad 21a of absorbent material which bears
upon the printing dies just before they are ad
vanced to printing position. The function of this
final cleaning cylinder is to distribute the ink
which has previously been applied to the dies in
a thin film upon the dies. By thus removing the
residual ink from the dies just after the printing
step and in wiping away any excess of newly lO
supplied ink from the surfaces of the dies just
prior to printing, uniform and distinct impres
sions upon the individual nuts are obtained free
from the blurring and smearing effect which re
properly position the nut in the adjustable- throat, - sults from accumulations of ink upon the print
after which the elevating bar is quickly lowered ing dies.
For furnishing ink to the printing dies, there
as the “drop” portion I4b of the cam rides under
its lower end.
When a nut is projected upwardly by the ele
20 vating bar, a continuously rotated feed wheel I5
having a tread Iäa of sponge rubber resiliently
engages the nut (several of which are indicated
Y in dotted lines in Fig. 3) and rolls it across the
printing die Ilia, of a rotary printing member IS.
The mechanism for actuating the marking
25
mechanism, as best indicated in Figs. 4 and 5,
comprises a continuous shaft I1 supported in
suitable bearings I1a in a direction transversely
of the machine frame. Mounted upon this shaft
30 adjacent its midportion are two opposed bevel
gears I8 and I9, the bevel gear I8 being keyed
to the shaft while bevel gear i9 is loosely rotat
able thereon. The bevel gear I8 is interrupted
by untoothed blank spaces I8a at quarter in
35 tervals while the bevel gear I9 is full toothed.
The rotary printing member Iâ is of cylindrical
form and is circumferentially provided with four
equidistantly spaced printing dies Ilia each com
posed of a block of resilient rubber bearing upon
40 its outer printing face the indicia to be applied
to the nuts.
The rotary member revolves upon a
shaft 20 extending horizontally outward from the
plate I2 which is fastened to the pair of upright
angle irons 9.
Upon the outwardly disposed end face of the
45
rotary member I6 is affixed a bevel gear 2l mesh
ing with both of the bevel gears I8 and I9 on
shaft I1. Bevel gear 2I has its teeth filed down
at intervals as indicated at 2| a corresponding to
50 the blanks Illa on bevel gear I8 so that when a
blank upon the latter gear rides into a comple
mentary stripped area 2Ia upon bevel gear 2l,
is provided an inking roller 3% rotatable'upon Va
pin 3l extending horizontally outward from an
arm 32. The arm 32 is fastened at its end to ~
cross plate IU by means of a screw 32a. This
inking roller is located a spaced distance below
the rotary printing member I6, and intermediate
the inking roller and the rotary printing member
is a transfer spool 33 having a circumference of v
polished metal adapted to bear against the inking
roller and against the dies Iíia as the latter are
periodically advanced toward printing position.
The transfer spool is similarly supported for ro
tation upon a pin 34 extending outwardly from an ‘
arm 35 which latter is fastened at one end to the
cross plate IB by the same screw 22m which fas
tens the bracket 22 to the cross plate. By loosen
ing the screws 32o. and 22a, the arms may be
swung down to permit convenient removal of the ;
inking roller and transfer spool lengthwise from
their pins 3| and 34 upon which they are retained
respectively by nuts 3 la and 34a.
In order to obtain a positive drive of the clean
ing cylinders, the inking roller and the transfer
spool so» that they will better perform their func
tions, the rotary printing member I5 is provided
with a p'mion 36 secured to its end face which is
disposed adjacent the plate l2. This pinion
meshes with a pinion 31 fixed upon the end face
of preliminary cleaning roller 25 and also with'a
pinion 38 secured to the end face of final cleaning
roller 21. Similarly the transfer spool 33 is pro
vided upon its inwardly disposed end face with a
pinion 39 meshing with the pinion 36 on the ro
tary printing member and also with apinion 46
fastened upon the end face of the printing roller
3Q. Thus during rotation of the rotary printingv
member the two cleaning rollers, the transfer
rolled by the feed wheel I5 over the printing die Y spool and the printing roller are all stepped si
IBa which at the time happens to be located in multaneously a fraction of a revolution to bring
printing position. Freely rotatable bevel gear I9 different portions of their circumferences into
the gears will be momentarily locked. During
thismomentary period of dwell, a nut will be

from theY rotary printing Ymember. Extending
within the frame and upon one end of this shaft
is mounted a sprocket 44 having a driving chain
45 which leads around a larger companion
horizontally outward adjacent the upper end cf
the bracket 22 is a pin 24 upon which is rotat
ably mounted a preliminary cleaning cylinder 25
having a circumferential pad 25a of absorbent
70 material, such asV felt, wrapped thereon. This
preliminary cleaning cylinder bears upon and is
adapted to wipe- the adhering coating of ink from
theprinting dies just after they have moved from
pinion 4l meshing with a large spur gear 42.
The large spur gear 42 is keyed to a shaft 43
disposed crosswise of and suitably j‘ournaled
sprocket 46 fixed upon shaft'28. _Shaft 28 is
rotatably mounted in the machine frame parallel
to shaft 43 and is provided upon its ends with
sprockets 41 and 4B. A transmission chain 49
extends between sprocket 41 and a companion
sprocket 59 mounted upon the end of the shaft I1
for driving `the latter shaft carrying the bevel
printing position.V Y Similarly a pin 26 is fastened
' gears I8 and I9.
75. to and projects from the upper end of bracket 23
A shaft 5I is supported for
75 z i
2,109,380
rotation in a pair of. standards 52 extending up
wardly from opposite sides of the frame, and a
chain 53 extends between sprocket 48 on shaft
28 and a companion sprocket 54 fixed to an end
of shaft 5I for driving the latter shaft. Feed
wheel I5 is keyed to a stub shaft 55 rotatably sup
ported upon the end of an arm 56, the opposite
end of which arm loosely embraces the shaft 5I.
The feed wheel is thus ñoatingly supported so as
to press the nuts ejected from the throat 'I' into
engagement with the printing dies Iâa of. the
rotary printing member I 6. The feed wheel is
positively driven in the direction indicated by
the arrow in Fig. l by a transmission chain 5l
extending between sprockets 58 and 59 on shafts
5I and 55 respectively. A roller 6G carried upon
the end of a, pivotally adjustable bracket 6I
fastened to arm 56 bears upon the chain and
takes up slack.
Reciprocating motion is imparted to the con
veyor chute 3 by means of the linkage (see Fig. l)
comprising a lever 63 pivotally connected at one
end to the bottom of the chute and at its other
end to one arm of a bell crank 64, and a second
link 55 extending from the other arm of the bell
crank to a box-shaped frame 66. The box frame
has a lip 6'! designed to ride upon the periphery
of the spiral cam disk I4. This box frame is
fastened to one end of. a rocker arm 68 which at
its other end 68a loosely encircles the shaft 43
without partaking of the motion of that shaft.
As will be apparent, the box frame 66 will be
gradually raised by the spiral cam disk I4 to
move the feed chute 3 downwardly with a vibra
tory motion, because of the notches I4a upon the
periphery of the cam, but when the cut-away
“drop” portion I4b of the cam arrives below the
lip 61 the box frame will drop, quickly shifting
the feed chute upwardly. Thus the nuts will be
fed from the hopper 2 to the marking mecha
nism with a combined vibratory and reciproca
tory motion. In a similar manner the elevating
bar I3, the lower end of which rides upon the
periphery of the cam I4, will gradually raise a
nut from the throat 'I with a jarring motion
into engagement with the resilient tread I5a of
the feed wheel l5.
The feed wheel will then roll
the nut across the face of a printing die lâa
so as to cause the nut to receive a printed im
pression from the die. When the “drop” p0r
tion I4b of the cam disk I4 rotates into a posi
tion below the lower end of the elevating bar,
the latter will fall, retracting its upper end into
the bottom of the throat l ready to receive an
other nut from the feed chute.
In order to maintain the nuts against lateral
displacement and to allow nuts of different

and slightly above a printing die I6a located in
printing position. The cradle is thus resiliently
supported at one end by the coil spring 'I4 and
at its other end by the stop plate 8 which is sup
ported upon the yieldable rubber pad 8a. Like
wise the cradle is free to rock a limited distance
about a, longitudinal axis by reason of the pivotal
mounting of the forward end of the cradle upon
the pivot pin 'l2 and because of the loose recep
tion of the pin l5 within its socket 16.
10V
In the operation of the machine just de
scribed, when a nut, such for example as a pecan,
is rolled along the rocker trough by the feed
wheel i5 the cradle is >adapted to yield vertically _
so as to allow the nut to be forced into engage 15
ment with the printing die I6a which is exposed
through the slightly oversize slot 'I8 in the cradle.
If the nut is misshapen, as for example if one of
its ends is larger than the other, then the cradle
will tilt about a longitudinal axis to compensate 20
for the lack of uniformity of the nut and the
face of the printing die Ita will bear quite evenly
upon the circumference of the nut.
f
It will be appreciated that only in rare cases
will a nut correspond in shape to the cross-sec 25
tional contour of the cradle and that ordinarily
the ends only of the nut will bear against the
concave sides of the cradle. In any event the
pressure exerted by the feed wheel I5 upon the
nuts will be resisted by the cradle and, especially 30.
in the case of the larger sizes of nuts, the rubber
printing dies will not be subjected to excessive
pressures which tend to shorten the useful life
of the dies as well as to c-ause blurredimpressions
to be imparted to the nuts. At the same time the 35A
printing dies being composed of rubber are capa
b-le of flexing to conform to differences and ir
regularities in the shapes of the nuts as such>
nuts are pressed into engagement with their
printing surfaces. It will also be apparent that
since the nuts are rolled across the printing dies, 40
the latter may, if desired, be elongated in the di
rection of travel of the nuts so as to apply an im- ‘
pression throughout a very large part of the cir
cumference of the shell. 'I‘his is a distinct ad
vantage over those types of nut branding ma
chines in which the nut must be momentarily
brought to rest while receiving the impression,
under which conditions the impression can be
applied only to a circumscribed area ofthe shell.
As has previously been explained, shaft I'I is 50
rotated by means of chain 49 which winds over
the sprocket 50 upon an end of this shaft. Bevel
gear I8 located upon this shaft adjacent its mid
portion engages the interrupted bevel gear 2| of
the rotary printing memberA I 6 and imp-arts inter
mittent motion thereto. During the period that
shapes to be uniformly pressed into engagement » the blanks' 18a upon the gear I8 engage the com
with the printing die as they are rolled there
over by the feed wheel I5, a rocker trough 'Hl is
provided as more clearly shown in Figs. 3, 4 and 5.
This rocker trough comprises a cradle 'II of con-_
cave trough form fastened at its forward or nut
receiving end by means of a pivot pin 'I2 threaded
- into the upper end of the depressible stop plate 3
and extending loosely through an opening in an
ear 'i3 bent down from the end of the cradle.
The rear or nut-discharging end of the cradle is
yieldably supported upon a coil spring 'i4 sur
rounding a pin 'I5 extending vertically downward
from the cradle into a slightly oversize socket 'I6
formed in a post TI supported upon the shaft il.
The bottom of the cradle intermediate its length
is provided with a slot 'i8 extending lengthwise
75 thereof and this slot is disposed in registry with
plementary stripped areas 2m upon the gear 2|,
there will be a period of dwell during which time
the rotary printing member Iii will be held sta 60
tionary by the interlocked gears. The elevating
bar i3 will then rise to press a nut into engage
ment with the feed wheel I 5 which rolls the
nut over the appropriately positioned printing
die Iôa. The other' three printing dies |6121,` of
the rotary printing member will at such time
be disposed, as illustrated in Fig. 5, with their
printing faces in Contact with the two cleaning
cylinders 25 and 2l and the transfer spool 33,
it being understood that the direction of rotation
of the rotary printing member will be as indicated '
by the arrow in Fig. 5.
The pads 25a and 21a
upon the círcumferences o_f the cleaning cylin
ders, while ordinarily composed of felt or; other
75
4
2,109,380
fibrous material, may, if desired, be composed of
superimposed layers of sponge rubber, felt and
blotting paper. By reason of the geared correc
tion of the cleaning cylinders, transfer spool and
inking roller to the rotary printing member, dur
ing each quarter of a turn of the rotary printing
member the preliminary cleaning cylinder 25 will
Wipe the adhering coating of ink from the print
ing die which is moved away from printing posi
10 tion, the transfer spool 33 will apply a fresh coat
ing of ink to another of the printing dies While
a new supply of ink is being added tothe polished
metal face of the spool by the inking roller 3U,
p and the ñnal cleaning cylinder 21 will remove the
15 superfluous coating of ink from the freshly inked
ñgure. Thus the inking roller may be effectively
sealed against dust and dirt and the ink >retarded
from drying out or from hardening or caking.
While the nut branding machine just described
is especially suitable for the marking of pecans or
similar types of nuts of generally oval contour, it
is also capable of employment with nuts of gen
erally spherical shape, such as walnuts, or with
fruit, such as oranges, which is adapted to be
rolled upon its circumference. It will be apparent 10
that various other changes in construction, ar
rangement and design in the nut branding mech
anism described above, representing a preferred
embodiment of the invention, m-ay be made with
out departing from the spirit of the invention.
What is claimed is:
l. In a nut branding machine, a printing die,
The inking roller 30, as best illustrated in the a resilient feed wheel located above the printing
cross-sectional View of Fig. 6, comprises a pair die and in spaced relation thereto, means for
introducing nuts into the space between the feed 20
20 of spaced disks 80 and 8| integrally connected by Wheel and the printing die, and a rocker trough
a tubular sleeve 82 adapted to slidingly receive
the pin 3! upon which this roller rotates. The disposed intermediate the feed wheel and the
disks 80 and 8l upon their opposed faces are printing die for guiding the nuts as they are
marginally reduced to provide annular hubs 89a rolled across the printing die by the feed wheel,
said rocker trough comprising a trough-shaped ‘
25 and 81a and telescoping over and extending be
cradle having an opening in its bottom immedi
tween these hubs is a sheet metal drum 83 hav
ing its ends soldered or welded to the hubs and g ately above the printing die and means yieldingly
being suitably provided with a multiplicity of supporting the cradle above the printing die but
perforations 83a. Upon the inner end face of permitting depression of the cradle to allow the
nuts to be pressed into engagement with the 30
30 disk 8l, is affixed, by screws 84A, the pinion 40.
`
'I'he disk 8l and pinion 4d are provided with printing die.
2. In a nut branding macln‘ne, a printing die,
aligned tapped openings, closed by a stud 85,
through which openings ink may be introduced, a resilient feed wheel located above the printing
die and in spaced relation thereto, means for in
by means of an eye dropper, into the interior
printing die which is about to move into print
ing position.
35 .of the drum which serves as an ink reservoir.
The perforations 83a are initially punched in a
flat metal sheet which is afterwards rolled into
tubular shape around the hubs. These punch
ings are so produced as to form burrs upon the
40
circumference of the drum.
As best shown in
the exaggerated detail view of Fig. ’7, the punch
ings define outwardly constricted tapered open
troducing nuts into the space between the feed ‘
wheel and the printing die, _and a rocker trough
disposed intermediate the feed wheel and the
printing die for guiding the nuts as they are
rolled across the printing die by the feed wheel,Y
Said rocker trough comprising al concave trough 40
shaped cradle having an opening in its bottom
immediately above the printing die and means
ings 83b extending from the interior of the drum
to its exterior which promote the ñow of the
ink from the interior to the exterior of the drum.
45 As will also be observed, these perforations are
punched at an angle in order to dispose the burrs
upon the drum in the direction of rotation of
the inking roller. Upon the circumference of the
drum 83 is Wrapped an inking pad 30a for apply
yieldingly supporting the cradle above the print
ing die but permitting the depression and tilting
ing a ñlm of ink to the surface of the transfer
spool. This pad comprises a layer, or a plurality
of layers, of felt which absorbs the ink passing
out of the drum through the perforations. The
troducing nuts into the space between the feed
wheel and the printing die, and a rocker trough
burrs surrounding the perforation, when thepfelt
is wrapped upon the drum, will penetrate the ma
terial and retain it from slipping. Furthermore,
due to the forward inclination of the burrs,
of the cradle upon a longitudinal axis to allow
nuts of various shapes to be evenly pressed into
engagement with the printing die.
3. In a nut branding machine, a printing die,

plate supporting the forward end of the cradle
tend to cause the burrs to biteV deeper into the
and a spring yieldingly supporting the rear end 60
60 pad and prevent slipping of the felt upon the
drum.
In order to protect the felt pad from exposure to
the atmosphere and also to afford a convenient
shipping container for the inking roller, a cup
86 (Fig. 8) is provided. The disk 8i of the print
ing roller is of slightly larger diameter than the
disk 80 and is circumferentially screw-threaded
as indicated at 86a. The cup 86 is interiorly
screw-threaded as at 81 adjacent its open end
and is provided upon its interior with cushion 88
at its closed end, the arrangement being such that
the cup is adapœd to telescope over the inking
roller and to screw onto the threaded circum
ference of the disk 8l in the manner shown in this
of the cradle to permit depression of the cradle
to allow the nuts to be pressed into engagement
with the printing die.

a resilient feed wheel located above the printing
die and in spaced relation thereto, means for
introducing nuts into the space between the
feed wheel and the printing die, and a rocker
trough disposed intermediate the feed Wheel and
the printing die for guiding the nuts as they are ,
