It is an object of the invention to provide a
method whereby a sole pressed against a shoe
may be fastened thereto by cement, and the ce
ment'or adhesive material quickly dried so as to
‘ reduce the, operation to a minimum of time.
‘Another object of the invention is the provision
of a method whereby the adhesive material may
be heated without injuring the leather or ma
terial from which the sole is made.
Another object of the invention is the provi
15 sion of a method whereby the heat may be ap
plied to the area of the sole, and the sole main
tained in a ventilated condition while being
. Other objects will appear hereinafter.
The invention will be best understood by a
reference to the accompanying drawing which
forms a part of this speci?cation, and in which,

The machine illustrated for carrying out my
method is designed to press a sole on a shoe 1
which is positioned on a suitable support 8 and
a heel engaging member 9. The shoe support 8
is provided with perforations, grooves or vents
35 8’ to serve as ventilators for ventilating the sole
of the shoe 1 so as to- permit escape of the vapors
as the adhesive material is drying.
The press consists of a trough shaped shell l0
projecting outwardly from one edge of which is
40 an eyelet l l which is adapted for slidable mount
ing on a supporting standard l2. A set screw l3
serves to ?x this trough shaped shell in position
on the standard l2. Secured to each of the edges
of the trough shaped shell is a plate M projecting
45 inwardly from the inner surface of the shell and
serving as a means-of attachment for one end of
the coil springs l5, the opposite ends of which
are attached to a ?exible woven presser member.
This presser member is formed from strips l6 of
50 resilient metal such as spring steel. It will be
noted that these strips it are extended longi
tudinally and transversely and that the strips
are spaced from each other to provide openings
in a sort of net-work structure. These openings
55 are provided for the purposes of ventilating the
pores of the leather sole, whereas were the presser Or
member to be solid, the drying could take place
only at the edges of the sole. This ventilated
presser-member permits of a quick drying and
aifords a more durable bond. Consequently, the
ventilation openings in the presser member coop- 10
erate‘with the ventilating openings in the shoe
As shown in Fig. 1, the presser member is free
of the trough at the outer end thereof, which is
that portion engageable with the shank of the
shoe with which used.
Swingably mounted on the shell by means of
studs l6 and H are yoke arms “3 and I9 project
ing upwardly from which is the yoke tree or lever
29. Swingably mounted on the yoke tree or lever
20 is the latch dog 2! held by the spring 22 nor
mally in engagement with the tooth segment 23
which is mounted on the outer surface of the
trough shaped shell Ill. The lower end of the
yoke arms 18 and I9 are ?xedly connected to and
preferably formed integral with the presser bars
24 and 25 which engage in the cut away portion or
recess 26 formed in the forward end of the trough
shaped shell l0. Secured to each of these presser
bars I4 is a plate 21 which projects inwardly of
the edge of the trough shaped shell and lies in
alignment with the corresponding plate [4, these
plates 21 serving to provide attachment means for
the forwardly positioned springs l5.
Projecting inwardly from the shell I!) at the 3 CA
rear end are bosses 28 and 29, which, together
with the forwardly positioned boss 3!], serve as
a means for attaching by means of the bolts 3|,
32 and 33, an electric heating element 34 in
position, this heating element being provided 40
with a terminal 35 which may be connected by
the cables 36 to a suitable source of electrical
energy. The construction is such that when the
standard I2 is moved downwardly against the
compression of the spring 31 by mechanism 45
which is not shown, the presser member con
sisting of the woven strips of metal 16 will en
gage the sole and press the same against the
shoe 1. By rocking the swingable yoke, the for
ward end of the presser member may be ?exed 50
to conform with the contour of the shoe so that
the sole may be engaged throughout its area and
?rmly pressed into engagement with the shoe.
At the same time, the current may be turned on
to provide through the heating element 34, the 55
necessary heat to quickly dry and set the glue
or other adhesive affixing means used to secure
to the leather inner sole of a shoe, comprising
interposing a layer of adhesive material between
the sole to the shoe.
two such soles to cover their entire meeting faces,
In this way, the use of the presser for press
ing a sole onto a shoe is reduced to a minimum
pressing their meeting faces together to force
amount of time, thus increasing the capacity of
the apparatus and making it possible to press a
leather and simultaneously with the application
greater munber of soles within a speci?ed time.
It will also be noted that the heat element is
10 in spaced relation to the sole so that the heat
is radiant heat which radiates through the at
mosphere for a distance before reaching the
sole. Experience has shown that by directing the
heat against the sole in this manner, more ef
1: ?cient results are obtained.
While I have described the method in its pre
ferred form, I do not wish to limit myself spe
ci?cally to the details herein set out but desire
to avail myself of such variations and modi?ca
tionsas will come within the scope of the ap
pended claims.
Having thus described my invention, what I
claim as new and desire to secure by Letters Pat
