6 Claims.
This invention relates to heels for women’s
shoes. It is an object of the invention to provide
heels which are strong, light in weight, easy to
make, and which can be made with novel design
5 effects.
The customary heel for ladies’ shoes, particu
larly heels of considerable height, usually con
tain considerable material. If such heels are
made of horizontal layers of leather or the like,
10 the heels are liablerto be excessively heavy, due
to the weight of the fastening elements which
are required to hold the layers together. Heels
of this type are usually made of wood owing to
the comparative lightness of the Wood. Such
15 heels, however, must be suitably covered and are
therefore not subject to alterations in shape to
conform to the shoe.
According to the present invention, heels may
be made of suitable materials such as leather or'
20 the like, the heels being `made with vertical l‘ami
naticns instead of horizontal laminations, so that
the layers can be held together solely by suitable
adhesives without incurring danger of failure of
the heel.

For a more complete understanding of the in
vention, reference may be had to the following
clude in their structure substantially vertical
plates, slabs or layers of material. Any suitable
material, such as leather, rubber, light metals,
or equivalents, may be employed.
By way of eX
ample, the heel illustrated in Figure 2 is made of 5
pieces or slabs of ñbrous material such as leather.
The heel seat, as shown, may consist of one or
more layers I0 of leather supported on a shank
consisting of vertical layers of leather including
transverse or breast layers I I and longitudinal 10
layers I2. Any suitable or desirable number of
layers may be employed for' each of these three
portions of the heel. As shown, two layers of
leather are used for the seat portions, two layers
II for the breast portion, and three layers I2 in 15
the rear portion, the latter being disposed in
planes extending longitudinally of the shoe. A
lift or horizontal layer I3 of leather may also be
provided at the bottom of the heel (referring to
its position when in actual use), this lift being 20
_in direct contact With the ground when the shoe
is being worn. The pieces of leather used to
make up the heel are preferably secured together
by suitable Waterproof adhesives. It is evident
that the heel, particularly if it is a high heel of 25
the Louis or spike variety, should be built' so as
description of certain embodiments thereof, and
to have considerable mechanical strength, since
to the drawing of which
otherwise the heel is liable to break in two if
transverse stresses are imposed thereon, as when
the Weight of the wearer is oiî center- or the Vheel 30
catches on the edge of a step. The arrangement
of the vertical laminae II and I2 is such as to
impart great strength to the heel in a manner
to oppose such stresses. The arrangement of
these laminae is such as to leave considerable 35

Figures 2 and 4 show two forms of heels which
in general are of conventional exterior shape but
have cut-away portions tending to reduce the
cubic content of the heel Without any material
reduction in the mechanical strength thereof.
55 Furthermore, as shown, both these heels may in
voids or cut-away areas I5 with the conven
tional heel contour defined by the shank, which
not only impart a novel and pleasing appearance
to the heel, but materially reduce the cubic con
tent, and hence the Weight, of the heel. It is 40
evident that, instead of leather, slabs of other
materials such as rubber, metal, Wood or the like
can be employed, or any desirable combination
of these or other materials, the arrangement of
the slabs in vertical planes being a feature tend- 45
ing to strengthen the heel mechanically as well
as to provide a pleasing appearance therefor.
Furthermore, heels can be made according to
the invention without the laminated structure
disclosed but having voids or cut-away portions 50
I5 to reduce the weight. Thus, for example, heels
having the general shape shown in Figure 2 can
be molded or cast of metal or any suitable plastic.
Figures 4 and 5 illustrate another variety of
heel embodying the invention. As shown in 55

these figures, the heel is of conventional general
shape and is composed of one or more layers 20
forming the seat, these layers being supported
by a shank consisting of transverse vertical breast
slabs 2| and longitudinal or front-to-rear slabs
22. Of the latter, the central slabs 25 are in
vertical planes and are flanked by outer slabs 26
and 21 which are secured to the central slabs 25
at their lower portions but which diverge from
10 the central slabs leaving voids 28. In this way
the material in the heel is reduced in volume and
the weight of the heel is correspondingly reduced.
The resulting heel further presents a novel and`
and a rear portion disposed in a vertical plane
parallel to said axis, said rear portion having a
thickness less than the Width of the breast por
tion whereby a pyramidal void is left in the
flanks of the heel on either side of said rear
portion.
2. A shoe heel comprising a seat portion con
sisting of one or more layers of leather, and a
shank portion supporting said seat portion, said
shank portion comprising a breast portion of one 10
or more vertical leather laminae in planes trans
verse to the long axis of the seat, and a rear
portion consisting of a plurality of laminae dis

3.. A shoe heel comprising a seat portion con
the transverse laminae are omitted and the body
of the heel is made up entirely of slabs: extending
in a front-to-rear direction. As shown `in Fig.
20 ure 7, the seat portion 30 is supported by vertical
slabs consisting of a. central set 31 disposed in
vertical planes. This set of slabs is ñanked by
other sets 32 and 33 secu-red to the lower portionA
of the cen-tral set but diverging upwardly froml
the central set to leave voids 35, these voidsv ex
tending through the heel in a front-to-rear di
rection. In order to form the curve of the breast
in this heel, a transverse piece 36 may be secured
beneath the forward end of the seat portion.
30 Or, if desired, the shank slabs may be cut to in
clude the curve of the breast as at 3:1y in Figurev 8.
The heel illustrated in Figures 9 and l0 is a
solid heel but employs the laminated structureA
on the same principle as that illustrated in- Fig
ure 2, the heel in. Figure 9 consisting of seat
laminae 40 supported by transverse laminae 4l
at the breast portion of the heel and longitudinal
laminae 42 at the rear portion of the heel, as
indicated iny Figure 10’.

the parts illustrated in the several figures> of the"

sisting of one or more layers of leather, and a
shan-k portion supporting said seat portion, said
shank portion comprising a breast portion of one
or more vertical leather laminae in planes trans 20
verse to the long axis of the seat, and a rear
portion consisting of a plurality of laminae dis
posed i-n substantially vertical planes and adhe
sively secured toî said breast portion, the thick
ness of said rear portion being less than the width
of the breast portion, whereby a pair of recesses
are left in the ñank of the heel.
4. A shoe heel having a seat portion and a
shank portion supporting said seat portion, said
shank portion comprising laminae arranged in 30'
substantially vertical planes, the breast portion
of said shank consisting of one or more laminae
disposed transversely with respect to the long
axis of the seat, the rear portion of the shank
consisting of a plurality of laminae parallel to
said axis.
5. A shoe heel having a seat portion and a
shank portion supporting said seat portion, said
shank portion comprising a. plurality of fibrous
slabs arranged in substantially vertical planes
parallel to the long axis of the heel seat, the outer
slabs being jointed to the lower portion of the
central slabs and iiaring away therefrom upward
ly to form front-to-rear voids in said heel.
(i. A shoe heel having a vertical height sub
stantially greater than its other dimensions, said
heel havingy a seat portion and- a shank portion
attached to and supporting said seat portion,
said shank portion consisting of a plurality of
substantially' vertical slabs secured together and 50'
materials may be employed asdesired. The in
vention is not to 'be' limited to the specific em
bodi'ments shown and described but may include
such modifications `and changes as comel within
the 'scope of the following claims.
