25 Claims. (Cl. 91-43)
This invention relates to nozzles for machines
for applying cement to the channels of shoe soles
after the cut-seam has been formed, thereby to
attach the channel flap to the sole. The invention
5 is herein illustrated as embodied in a. machine of
the extrusion type.
It is well understood in the manufacture of
shoes that a seam for attaching'the cutsole may
be formed at the bottom of a channel cut ‘in the
10 sole and that after
seam has been formed
the channel ?ap may be cemented to- the sole
to hide the seam. Prior to the formation of the
scam the channel flap
lifted to facilitate the
sewing operation, this usually being done while
the sole is in temper, and as a result the flap
is wrinkled transversely of its length, especially
around the toe end of the sole. When the time
comes for the application of cement to the chan
nel, speci?cally to the channel base and the in
20 side of the channel
the flap may be dry
‘wise of the channel is a cover plate or deflector,
a portion of which ‘is ‘brought into cement-tight
engagement with the end face‘ of ‘the nozzle, and
the remainder of which is spaced from the end
face by reason of a cut-‘away portion which is
illustrated as formed in the cover plate, thus pro
viding a shoulder ‘which determines the end of
10
‘each of the lateral passages.
Still another feature of the invention resides
in a ‘novel construction greatly facilitating the
even distribution of cement through the two lat
eral passageswhich ‘deliver. cement to ‘the ?ap
and the channel bed, by equalizing the frictional 15
resistance 'of‘the .out?owing cement. To this ‘end,
‘the end face of the nozzle in the illustrated con
struction is recessed, leaving marginal portions
of uniform Width adjacent to the edges ‘of the end
face.

'
and as a result quite sti? and hard. ‘ That being
When applying :cement'of the polymerized chlo
the case the under surface of the flap provides
a wrinkled surface. Obviously, the contour and
outline of the sole are both irregular. Coating
roprene type there is a tendency for the cement
to be repelled 'by the leather. This is overcome,
in accordance ‘with still another feature of the
12. shoe channels has commonly been performed by
means of a rotary brush.
With the rubber ce
ments ordinarily employed this sort of an appa
ratus is very successful. However, if "the ma“
chine is to be used with cements of the pyroxylin
30 type, or the polymerized chlcroprene type, vone
form of whichis commonly known as ‘Neoprene,
then it is essential to avoid soiling the outside of
the shoe because of the difficulty in removing such
cements from the shoe upper, for example. It is,
furthermore, even more essential that exactly
the desired quantity should be applied in order
that there may be no squeeze-out when the chan
nel ?ap is pressed into place.
Accordinglytan important object of the "inven~
tion is to provide an improved nozzle for a chan
nel cementing machine of the extrusion type by
invention, by the provision of duplicate sets of I25
lateral passages bymeans of a pair or" superposed
cover' plates, the intermediate one of which ‘is
apertured to‘pr'ovide communication between the
two sets of passages.
As a result of this con
struction the cement extruded ‘through the ?rst 30
set of passages is effective to wet the leather and
this greatly ‘facilitates the application thereon of
a coating ofcement of the desired thickness.
Other features of the invention relating to the
structure of the machine are not'clairned herein -
since they formthe subject ‘matter of a divisional
application Serial No. 111,453, ?led Nov. 18, 1936.
These and other features of the invention will
be described-fin ‘the following speci?cation taken
in connection with the accompanying drawings, 40

'
For a machine of'this type a nozzle must be
employed which is
to enter the channel
and to apply cement to the bed of the channel
and to the inner face of the channel ?ap in sub
so
through the nozzle. ‘Cooperating with this end
face to form lateral ‘passages extending height
stantially equal quantities. To this end, a'feature
of the invention resides in an improved nozzle
construction which, as illustrated, is V-shaped, is
‘tapered to form a leading edge, and has an end
face transverse to the length of the channel in ’
U1 Cal which is the outlet opening of a passage leading
