Rockably mounted on the plate 60 by means of a pivot
pin 75 is a socket member 76 into which is threaded one
end of the connecting rod 77, the other end of the con

head 135 forwardly. However, the springs 137 permit
crank 82, which crank is also mounted on a crankshaft
83.
The crankshaft 83 is supported in spaced aligned
bearings 84, 85 mounted on an angle member 86 which
extends between the posts 4, 5 downwardly of the top
angle member 9. Mounted on the other end of the
crankshaft 83 is a sprocket 87 around which is trained
a drive chain 88, and the drive chain 88 is also trained
the head 135 to be shifted rearwardly of the end of the
bar 134 a limited amount. At its other end the delivery
bar 134 is formed with a longitudinal slot 138 which
receives a clamping screw 139, the latter being adapted
to be rigidly clamped along the slot 138 in any one of
a number of selected positions.

As seen
latter being rigidly secured to a shaft 95. Journalling
the shaft 95 in downwardly spaced relation to the shaft
90 are bearings 96, 97 which are mounted on a pair of
angle members 98, 99 extending transversely of the base
2 at the upper end thereof. A roller chain 99' is trained
around the sprockets 93, 94.
Also rigidly mounted on the shaft 95 adjacent the
bearing 97 is a worm wheel 100, which meshes with a
worm 101 mounted on a worm shaft 102 as best seen
in FIGS. 7 and 14. The worm shaft 102 is journalled
in the bearings 103, 104, which are rigidly secured to
spaced parallel cross beams 105, 106 extending between
the bars 22, 23. A pulley 107 is rigidly mounted on the
worm shaft 102, and trained around the pulley 107 is a
plurality of drive belts 108 which extend downwardly
through the base 2 and are trained around a pulley 109‘
which is mounted on the shaft of a conventional electric
motor 110. The motor 110 is adjustably bolted to a
pair of transverse channels 111, 112 which are welded
or otherwise rigidly secured to the bottom angle mem
bers 11, 13.
Referring more particularly to FIGS. 7 and 16, it will
be seen that the end of the worm shaft 102 is provided
with a bevel gear 113 which meshes with a beveled pin
ion 114 mounted on a hand Wheel shaft 115, the latter
projecting through the bar 22, and being provided on
its outer end with a hand wheel 116. The shaft 115 is
also journalled in a bearing 117 depending from a trans
verse member 118, and also mounted on a shaft 115 is
a collar 119. A spring 120 encircles the shaft 115 and
to ‘a long follower rod 145.
The follower rod 145
reciprocates in spaced pillow blocks 146, 147, and at
1ts forward end the follower rod 145 is provided with a
small roller 148 which serves as a follower for a cam
149, the latter being mounted on the shaft 90.
Mounted at one end on the pillow block 147 is a pair
of return springs 150, 151, the other ends of which are
secured to a pin 152, the latter in turn being secured
to the follower rod 145. The return springs 150, 151
bias the follower rod 145 towards the cam 149 and holds
the roller 148 thereagainst. Rotation of the cam 149
drives the follower rod 145 causing the delivery bar 134
to move horizontally back and forth across the face of
the plate 27.
Secured to the journal plates 28, 29 in downwardly
spaced relation to the connecting plate 30 is another hori
zontal journal plate 153 which is supported on spaced
parallel supports 154, 155. Mounted on the journal
plate 153 and connecting plate 30 are bearings 156, 157,
158, 159 which journal spaced, parallel, vertical drum
shafts .160, 161, and rigidly mounted on the drum shafts
‘160, 161 are drums 162, 163. The drums 162, 163 are
provided on their outer peripheries with cutting dies
164, 165 which extend parallel to the axis of rotation of
the shafts 160, 161 and are preferably rounded off at
their ends. The cutting dies 164, 165 mesh, and inter
posed alternately of the cutting dies 164, 165 are U-shaped
rubber strips 166, 167. Consequently as the drums 164,
165 rotate the cutting dies on one drum will press against
‘the rubber strips 166, .167 of the other drum. The bear
ings 158, 159 are eccentrically mounted in a conventional

so that the drum 164 can be adjusted toward and away
from the drum 165. Mounted on the lower end of the
drum shaft 160 is a bevel gear 170 which meshes with a
bevel gear 171 on the shaft 90 so that upon rotation of
the shaft 90 power will be delivered to the drum shafts
160, 161 causing the drums 162, 163 to rotate in the
opposite directions.
cessively mesh with each other, and also mounted on the
shaft 227 adjacent the gear 236 is a sprocket 238. Trained
around the sprocket 238 is a roller chain 239 which is
also trained around a large diameter sprocket 240, the
latter being rigidly mounted on the drum shaft 160.
Mounted on the cross beams 261, 202 laterally outwardly
of the arms 217, 218, 219, 220, 221, 222, 223, 224 are
blocks 240, 241, 242, 243 which receive springs 244, 245,
the bearing 156 is a gear 172 which meshes with an idler
246, 247 for resiliently biasing the rollers 229, 230, 231,

FIG. 9.
The idler shaft 174 is journalled in a ?ange
plate 175 which extends rearwardly from the connecting
247 may be varied by means of bolts 248, 249, 250, 251
which are threaded into the blocks 240, 241, 242, 243.
As best seen by reference to FIG. 10 the rollers 229, 230,
231, 232 ‘terminate in closely spaced relation to the ele
plate 30. Rigidly mounted on the forward end of the
plate 27 are vertically spaced bearings 176, 177 which
rotatably support a feed roller shaft 178, the latter being 15 ments 210, 211 and triangulated member 212 so that the
provided with a gear 179 meshing with the idler 173.
Also mounted on the feed roller shaft 178 is a rubber
feed roller 180, a portion of which projects through an
opening 181 forming in a plate 27. Mounted on vertically
spaced bearing blocks 182, 183 and on the other side of
the plate 27 is a rock shaft 184 having rigidly clamped
thereon an outwardly extending arm 185, and rotatably
mounted on the arm 185 by means of the journal pin 186
is a shiftable rubber feed roller 187.
The arm 185 is
provided at the end opposite the roller 187 with a stop
‘188 which is adapted to bear against the plate 27 between
the feed rollers ‘180, 187 and drums 162, 163. Mounted
on one face of the arm 185 is a leaf spring .189 which also
bears against the plate 27 adjacent the stop 188. A fol
lower arm 190 is also mounted on the rock shaft 184 and
the follower arm 190 is provided on its outer end with a
roller 191, the latter being adapted to periodically contact
a cam 192.
line of contact between the rollers 229, 230 is located
just outside the passageway 215 while the line of contact
between the rollers 231, 232 is similarly located just out
side the passagcway 216. The springs 244, 245, 246, 247
permit the rollers 229, 230, 231, 232 to separate a limited
amount while at the same time allowing the gears 234,
235, 236, 237 to remain in mesh so that all four shafts
and associated rollers 229, 230, 231, 232 will be power
driven through the roller chain 239.
Secured to the base 2 forwardly thereof is an out-rigger
frame 252 comprising a rear upright 253, a somewhat
smaller front upright 254, and an intermediate upright
255. The outrigger frame 252 also includes longitudinal
frame members 256, 257, 258 a transverse angle member
259 at one end, and a short transverse supporting strut
260 at the other end. The rearwardmost frame member

the result that the drums 162, 163 are in a precisely pre

the comb-shaped elements and only a small portion need
be trimmed oif of one of the elements thus formed. As
the blanks are fed between the drums 162, 163, the rub»
