The machine is illustrated-with reference to
splitting an outsole 20 (Fig. 10) and a skeleton
insole 22 ‘from a sole blank 24 (Figs. 2 and 3).
The sole blank 24 is progressively forced against 55

the periphery 26 of a matrix drum 28 by a presser
member 30 (Fig. 3) as it is moved past a cutting
section 32 of the band saw 34 by a feed member
36, the forepart of the sole blank 24 being dis
torted transversely as it is moved past the cut
ting section 32 in order to form in the forepart
of the insole 22 an opening 38 which is substan
tially complemental to a central projection 40
10
of the forepart of the outsole 20.
When the outsole 20 and the insole 22 have
been incorporated in a shoe 2I (Fig. 11) the cen
tral projecting portion 40 of the outsole and the
margin or rand 23 of the insole have their upper
surfaces flush with each other to form a sub
15 stantially continuous face which serves as a com
fortable support for the foot. It will be noted
that the overlasted margin 25 of the shoe upper
is positioned between the rand 23 of the insole 22
and the margin of the forepart of the outsole
20 20 and that'if the projection 40 of the outsole
is to be ?ushw-ith the rand 23 of the insole the
thickness of the overlasted counter portion 25
of the shoe should be compensated for by form
ing an outsole 20 the thickness of the projecting
25 portion 4070f which is substantially equal to the
combined thickness of- the margin of the forepart
of the outsole 20, the overlasted portion 25 of the
shoe upper, and the rand 23 of the insole.
As
above stated, after splitting a skeleton insole and
30 an outsole from a sole blank by the use of a knife,
it has been proposed to remove material from the
upper face of the margin of the forepart of the
outsole in order to compensate for the thickness
of the overlasted margin of the shoe upper. In
35 the illustrated machine the kerf removed by the
saw is of substantially the same thickness as the
overlasted‘margin of the upper and it is therefore
unnecessary to reduce the margin of the forepart
of the outsole as above described.

The band saw 34 is mounted upon a lower pul
ley (not shown) and upon an upper pulley 42
which is rotatable upon roller bearings 44, 46
and 48 (Figs. 1 and 3.) The-pulley 42 has a
circular groove 50 of suitable shape to receive
45 the bearings 44, 46 and 48 and has a tapered por
tion 52 beyond which the cutting section 32 of
the saw 34 projects. The tapered portion 52 of
the pulley 42 forms a ?aring opening 54 which
is shaped to receive the matrix drum 28 and in.
cludes the forward'end of a tray 56 arranged to
receive the split outsole. The skeleton insoles
22 are grasped by the operator as they override
the band knife ‘34 and are stacked. The roller
bearings 46 and 48 are mounted upon threaded
55 studs 58 (Fig. 3) secured by nuts 66 to a bracket
62, the bearing 44 being mounted upon an ec
centric portion 64 of a stud 66. In order to
insure that an effective rolling fit between the
bearings 44, 46 and 48 and ‘the pulley 42, the
60 eccentric portion 64 may be swung toward an
adjacent portion of the pulley until the bearings
are forced against the bottom of the annular
groove 50, after which a nut 'I'U'is turned to
retain the eccentric‘ in its adjusted position.
The bracket 62 is formed integral with a pair
of bowed carrier frames 12 connected by an ar
cuate portion 14 which engages within arcuate
guideways 16 of a base 18 secured by bolts 80 to
a pedestal 82. The curvature of the guideway
16 is substantially coincident with the upper~
most portion of the'cutting section 32 of the
saw 34, the arrangement being such that when
a worm 84 which is in meshing engagement with
a gear 86 formed at the under side of the arcuate
plate 14 isturned, the pulley 42 is swung about
the uppermost portion of the cutting section 32
thereby properly adjusting the pulley 42 in order
to insure that the cutting edge of the saw shall
remain in a plane as it travels over the pulley.
The arcuate plate 14 is held in the guideways
16 by rolls 88 (Fig. 3) which are eccentrically
mounted upon the base 18. The carrier frame
72 is normally secured to the base 18 of the ma
chine by screws 90 which are in ‘threaded en
gagement with the carrier frame and pass 10
through elongated slots 92 formed in the base ‘I8.
The carrier frame 12 comprises a pair of
bosses 94 which support a bearing shaft 93 upon
which a pair of side plates 98 are swivelcd, the
lower ends of the side plates being in engage 15
ment with a pair of cams I06 (Figs. 1 and 3)
formed integral with a bar I62 pivotally mounted
upon the carrier frame 12. The side plates 93
are provided with laterally projecting bosses I04,
respectively, bored to receive a shaft I66 to which 20
the matrix drum 28 is keyed. The matrix drum
28 may be conveniently adjusted with relation
to the cutting section 32 of the saw 34 for locat
ing the split in the sole blank 24, by swinging
a handle I08 of the eccentric bar I02 thereby
raising or lowering the side plates 98 and there 25
fore the drum 28 with relation to the cutting
section 32. The side plates 98 are conveniently
locked to the carrier frame ‘I2 by screws IIO
(Fig. 3) which are in threaded relation with the 30
carrier frame and extended through arcuate
openings II2of the respective side plates 98.
The presser member 30 which progressively
forces the sole blank 24 fed past the saw 34
against the periphery 26 of the rotary drum 28
comprises a plurality of resilient ?ngers I I4 (Figs. 35
1 and 2) and a shank portion H6 (Figs. 2 and 3)
which is secured by screws I I8 to a sleeve I28
mounted upon a rod I22 supported by the side
plates 98.
The feed member 36 is pinned to a shaft I24 40
rotatably mounted in bosses I26, respectively, of
a pair of connected arms I28 (Figs. 2 and 3) the
rear ends of which are pivotally supported upon
the shaft 96. The left arm I28, as viewed from
the front of the machine, has a depending por
45
tion I 30, the lower end of which carries a cam
roll I 32 arranged to engage a cam I34 (Fig. 3)
secured to the matrix drum 28 by screws I36.
The sleeve I20 (Figs. 2 and 3) to which the
presser member 30 is secured comprises a pair 50
of levers I38, I39, respectively, (Fig. 2), the le
ver I38 carrying a roll I40 which is forced by
springs I42 into engagement with a ledge I44
formed upon the depending extension I30 of the.
arm I28. The upper ends of the springs I42 are 55
connected to corresponding levers I38 and the
lower ends of the springs are adjustably con—
nected to screws I45 which pass through recesses
formed in corresponding side plates 98 and are 60
in threaded relation with nuts I46. The springs
I42 cause the cam roll I 32 to be forced against
the cam I34 as well as cause the presser mem
ber 30 to force the sole against the periphery
26 of the drum 28. In order to insure that the
cam roll I 32 shall effectively follow the cam I34
the arms I28 are forced downwardly under the
action of a strong spring I48, the upper end of
which is in engagement with a yoke I50 formed
integral with the side plates 98 and the lower end 70
of which is in engagement with a cross bar I52
whichis secured to the arms I28. As illustrated
in Fig. 3 a sole blank 24 has just been positioned
in the machine, the cam I 32 being in engage
ment with the high portion I54 of the cam I34
v3
2,137,326
and being about ready to be moved into engage
mentiwith a low portion I56 of ‘the cam thereby
causing the feed member‘ 36 and the presser
member 30 to be lowered to‘ their operating
positions.
‘
When the arms I28 are in their lowered position
the axis of the shaft I24 substantially coincides
with the axis of the stub shaft I88. The shaft
I06 is driven by a pulley I91 which is operated
by a belt I99.
‘
‘.WhiIe the cam‘ roll I32 is riding on the high
portion I54 of the cam I34 the sole blank 24 is
fed into the machine until the toe end of the
sole .blank engages a bifurcated gage ‘I58 (Figs.
‘2 and 3) which when in its lowered operative
‘ position‘is located immediately ahead of the
cutting section32 of the saw 34. The bifurcated
‘gage I58 is pivotally mounted upon a rod I60
and is provided with a groove I82 (Fig. 2) in
is
which engages a screw I64 carried by a sleeve
I66 secured to the arms I28. When the arms I28

is provided with gages I98, 280 (Fig. 2) ‘Which 10
engage opposite sides of the forepart and the

stated, the sole is positioned lengthwise of the
