2 Claims.
My invention relates to shoes and one of the
objects is the production of a shoe that has the
good wearing qualities and flexibility of a sewed
shoe and; the smart lines and- dainty, yet sturdy,
character of a cemented shoe.
In a shoe, where the sole is cemented to the
upper from heel‘ to toe, there isa chance of
the, sole coming off the shoe, particularly around
the forepart of the shoe. - Then again, there are
10 objections to a cemented sole, because it is
claimed that it burns the feet of the wearer.
In the manufacture of a sewed shoe, when
channeling the shank of the outersole and then
sewing down the shank, the shoe becomes dis
torted and takes away from the shoe-maker the
opportunity to produce a clean cut shank, which
is desirable especially, in women’s footwear to
However, when the shank is cemented to
the shoe on the last, it insures that the shoe
will then have the same perfect lines as are put
in the arch of the last.
By sewing only the forepart of the shoe by
the McKay or lockstitch method of sewing and
cementing the shank, the operator is able to
hold the shoe ?at and thus control the original
shape of the shoe and the ?tting measurements.
In connection with the manufacture especial
ly, of ladies’ shoes, in order to help support the
arch, it has been the practice to provide a bulge

Fig. 3 is a section on the line 8-8 of Fig. '7.
The shoe is lasted in the customary manner
of making McKay shoes in which, after the in 10
nersole l is correctly positioned on the last, the
upper 2 and lining 3 are pulled tightly over the
last and fastened to the under surface of the
innersole by means of tacks 5 (or other used
methods) which penetrate the innersole and are 15
clinched against the steel bottom of the last.
After the application of a steel shank stiffener

the outersole.
The outersole ‘I is provided with the offset or 20
bulge 8 at the shank and is also channeled at
9 along the forepart of the sole only. The sole
is molded into shape as shown in Figs. 3 and 4
and is then laid on the upper and held in place
by the layer of cement Ill which has been ap
plied to the outersole, temporarily adhering the
sole to the forepart of the shoe and permanently
