Application January 8, 1936, Serial No. 58,056
36 Claims.
This invention relates to shoes and the manu
facture thereof and is illustrated herein with par
ticular reference to improved bottom units for
shoes and to improvements in methods of mak-‘
5 ing shoes and shoe bottom units.
Objects of the invention are to provide an im
proved shoe bottom or outsole member adapted
for attachment as a unit to a shoe and to provide
improved methods of making shoes and shoe bot
tom units.
In accordance with one aspect the illustrated
invention provides an improved method of mak
ing shoes which comprises forming a shoe bottom
member or unit consisting of a heel and a shank
.piece, covering the heel and shank piece with
sheet material which overlaps the edges of the
attaching surfaces of the heel and the shank
piece, and thereafter applying the pre-covered
member as a unit to the bottom of a lasted shoe.
20 As herein illustrated, a conventional wood heel
is rigidly secured to a relatively in?exible shank
piece conforming substantially in shape to the
shank and heel portions of a last bottom. The
covering for the heel and shank piece may be up
(Cl. 12—142)
driven fastenings such as tacks or staples. The
?ller piece may be applied ?rst to the inner side
of the covered shank piece and the outsole mem
ber applied afterwards to the outer side of the
shank piece and to the adjacent surface of the
filler piece.
_
In accordance with another aspect of the il
lustrated method a relatively inflexible shank
piece may have a heel rigidly secured thereto and,
before a covering is applied, a ?ller piece of leath
er or similar material may be secured to the outer
side of the forward end of the shank piece.
When this method is practiced the heel and shank
piece are next covered as described with sheet
material such, for example, as kid or upper
leather of a similar quality. The portion of the
covering at the forward end of the shank piece,
which preferably extends a little beyond the
shank piece, is roughed in the usual manner and
the short outsole is attached thereto and to the
outer surface- of the ?ller piece by cement to
complete the construction of the shoe bottom
unit. In each case the portions of the ?ller and
outsole which overlap the shank piece are skived

The precovered heel and shank piece is pro
vided at its forward end with a forepart sole
member which is vsecured to the shank piece pref

As herein illustrated, the
bottom unit has a full width shank and heel
forepart sole member comprises a short relatively
portion which normally provides a rigid support
?exible outsole member of leather or similar ma
for the foot without a metal shank stiffener. It
has a flexible forepart a portion of which is
adapted to serve as a .?ller to take up the space
terial, such as arti?cial leather or ?ber, arranged
to cover only the forepart of the shoe bottom, and
a ?ller piece of thin ?exible material secured by
cement to the forward end of the shank piece and
to the ?exible outsole, thereby reinforcing the at
tachment of the latter to the shank piece. The
two forepart sole members arepréfe'rably applied
separately to the shank piece and their attach
ment thereto may, if desired, be reinforced by

24. The shank piece may be formed from a
solid piece of wood or it may be made from
mobile material such as plastic wood, ?berboard
or similar material molded into the required
shape. The shank piece is rigidly secured to the
heel -20 by screws 26 and, as illustrated in Fig.‘ 2,
attaching surfaces of the heel and the shank
piece.
‘
The invention also provides as a new article of
manufacture an improved shoe having a bottom
or sole member which is preformed and precov;
ered before it is applied to the shoe. At its rear
portion the preformed sole member is relatively
in?exible and is shaped to conform to the shank

as a unit. In forming the heel and shank por
tion of the shoe bottom member a wood heel 2|, 1 the edges of the inner surface of the shank piece
herein illustrated as a Louis heel, is provided and to cause the covering to lie smoothly over
at the forward end of its attaching surface with the outer surface of the shank piece and the
breast of the heel. Figs. 5 and 6 illustrate, re 75

spectively, how the heel and shank piece cover
ings 36, 38, are wrapped around the heel and
over the outer surface of the shank piece and
how their marginal portions are secured in the
slots 36 in the breast of the heel and are also
secured to the attaching surfaces of the heel
and the shank piece.
The covered heel and shank piece is next pro
vided at its forward end with a relatively ?exible
10 sole member 42 (Fig. 7) which conforms substan
tially in outline to the shape of the forepart of
a last bottom but is considerably smaller than a
last bottom. The ?exible sole member as herein
illustrated is secured to the inner side of the for
15 ward end of the covered shank piece by an ad
hesive, such for example, as pyroxylin cement.
If desired the attachment of the sole member to
the shank piece may be reinforced by driven fas
tenings (not shown) such as tacks or staples. As
20 shown in section in Fig. 8, the portion of the sole
member 42 which overlaps the end of the shank
piece 24 is skived to a relatively thin edge to
prevent the formation of a, shoulder or ridge in
the bottom of the shoe. The sole member 62 is
preferably formed of ?exible leather or similar
material such as arti?cial leather and is substan
tially as thick as the upper materials which are
to be used in the shoe so that it will serve as a
?ller piece to ?ll up the space between the inner
edges of the overlasted marginal portions of the
3
the shoe bottom member applied to the shoe 48
with the aidof any well;known sole-attaching
press.
Figs. 9 and 10 illustrate a somewhat different
method of forming a complete shoe bottom mem
ber adapted for attachment as a unit to a shoe.
This method comprises attaching a relatively
in?exible preformed shank piece 50 and a con
ventional Wood heel 52 together by screws 54 in
the manner already described. The combined 10
shank piece and heel are‘ then provided at the
marginal portions of the breast of the heel and
the rear portion of the shank piece with cover
receiving slots 56) as described above. A forepart
sole member or ?ller piece 58, substantially the 15
same as the member 62, is then attached to the
outer surface of the forward end of the shank
piece 50 by an adhesive, such for example, as
pyroxylin cement. As shown in Fig. 9, the mem
ber 58 is of a size and shape to ?ll in the space 20
between the overlasted edges of the upper mate
rials at the forepart of a shoe bottom and is
substantially as thick as the upper materials.
The heel 52 is then covered with sheet material
such as a thin layer of upper leather 60 and the 25
outer surface of the shank piece 50 and the
breast of the heel are covered with a separate
layer of upper material 62, the margins of the
rear portions of the material being inserteduin'
the slots 56 and secured therein by the rubber
upper at the forepart of the shoe. Except for
its thickness and ?exibility the quality of the
cement which secures the covering to the heel
material forming the sole member or ?ller piece
42 is of no consequence and accordingly pieces
of ?exible leather which would otherwise go to
waste and commonly known as “splits” or “skiv
ings” may be utilized for this purpose.
the covering 62 extends beyond the end of the
After the ?ller piece 42 has been secured to the
combined heel and shank piece in the manner
described, a short outsole member 44 conforming
in shape to the forepart of a shoe bottom is at
tached to the outer side of the forward end of
the shank piece by an adhesive such as pyroxylin
cement, as shown in Figs. 7 and 8. Prior to the
attachment of the forepart outsole member 44- to
the ~ shank piece, however, the intramarginal
portion of its inner or flesh surface 46 should
be coated with cement, preferably pyroxylin, so
that it will adhere to the outer surface of the
, ?ller piece 42 thereby strengthening the attach
ment of the outsole member to the heel and
shank piece and eliminating all danger of the out
sole member separating from the shank piece
during the wear of the shoe. As shown in Fig. 8,
the rear portion'of the outsole member 44 is also
skived to a relatively thin edge to form a neat
joint where it overlaps the covered shank piece
24 as well as to increase the ?exibility of the shoe
at the ball line portion. A heel lift 65 may be
attached to the tread surface of the heel in the
usual manner to complete the construction of the
shoe bottom member. The completed shoe bot
tom member made in accordance with the
and shank piece.
It will be noted in Fig. 10 that
'_?.ller piece 58 for a short distance and.thus serves
to strengthen the attachment of the filler piece
to the shank piece. The end of the ?ller piece
is skived to prevent the formation of a ridge on
the outer surface of the shoe bottom. ,
A forepart outsole 64 is now attached to the
forward portion of the covering material 62 which 40
covers the shank piece, preferably by pyroxylin
cement, and the outsole is also secured by ce~
ment to the adjacent surface of the filler piece 58
in the manner described to complete the con
struction of the shoe bottom member except for 4.5v
the attachment of a heel lifti68 which may be ap
plied in the usual manner. The portion of the
outsole member 64 which overlaps the forward
end of the shank piece 56 is skived to a relatively
thin edge as shown at 66 to prevent the forma 50
tion of a shoulder on the shoe bottom and to in
crease the flexibility at the ball line of the shoe.
The shoe bottom member illustrated in Fig. 10
is ready for attachment as a unit to the bottom
of a shoe. If desired, after one of the shoe bot
tom members of the present invention has been
attached to a lasted shoe such as that shown in
Fig. 11, the last may be withdrawn and the at
tachment of the‘wood heel to the heel seat por
tion of the shoe bottom, that is, to the insole 60'
and overlasted upper materials, may be strength
ened by the usual inside heel attaching nails al
