The art is acquainted with attempts to simu
tations corresponding generally to leather grain
or embodying other designs, and colors have
20 been applied to ‘such sheets.
All such heels made heretofore, so far as I
am aware, have a slick glazedv artificial appear
ance which detracts from the simulation in
tended and renders the heel less desirable from
25 an -appearance standpoint than a heel composed
of leather lifts.
Also the finish is susceptible to deterioration
due to the removal of the color material applied
to the face of the Celluloid by scratching, abras
30 ions, the weather, or combinations of these fac
tors. As is well known in the trade, it is almost
printed thereon a light and shade or color re
Figure 3 is an isometric view of a die or block
of metal which has in bas-relief thereon a fac

leather heel shown in Figure 1 which gives the 20
leather its characteristic texture.
Figure 4 indicates a transverse section through
the sheet of material shown in Figure 2.
Figure 5 shows a heel of Wood or like material
having applied thereto the cover shown in Fig

The all leather heel l which forms the basis
for the design of the finished product illus
trated consists of a plurality of individual lifts

leather and having different widths and thick

of leather lifts and possessing suillcient strength
to be serviceable. Furthermore, any style .heel
made of leather lifts, and particularly the
cheaper heels formed by compressing leather
scraps, are subject to early deterioration due to
checking and the separation of the leather ele
tour of the heel. 'I'he successive lifts have indi
vidual coloring and graining which is inherent
in the leather and is directly responsible for the 35
pleasing variegated’eft'ect characteristic of such
material. For example, some of the lifts will
be much darker than others and some may have
variation in the degree of light and shade from
one side to the other. Some of the lifts will have
fairly smooth surfaces where the cut has been
. ments when wet.

Figure 1 illustrates a heel made of leather Ul
lifts each comprising a sheet of solid leather and
each presenting a different shade and texture to
the eye depending upon the color of the piece of
leather from which the lift was formed and upon
the quality of the grain and the direction of the 10
'I'he m-ain object of the present invention is
to produce a heel of wood or similar strong con
struction with a cover applied thereto which
will simulate a high-grade leather lift heel and be
free of the above mentioned objections to leather
_-, heels or to covered heels as heretofore manu
factured.
l
,Another object of the invention is to obtain
novel color effects on covered heels in a manner
which will avoid the early deterioration of the
0 heel’s appearance due to removal of particles of
the coloring material.
A preferred embodiment of the invention is il
lustrated in the accompanying drawing, which
is to be understood as largely diagrammatical

made lengthwise of the grain and others will
have pebbled or pocked surfaces most noticeable
where the cut has been made transversely of the
grain. 0n some lifts the relatively smooth sur- 45
face may extend throughout the perimeter of
the heel and may be of a. constant shade of
color while in other lifts there will be substan
tial variation both in texture and coloring as
the eye follows the lift around the heel.
- Having selected an attractive leather heel as a
model, the same may be reproduced on a ñat sur

2. A method of finishing a cover for a shoe
heel body of wood or similar construction so as 20
to simulate a heel made of leather lifts which
comprises photographing the light and shade of
the leather lift heel onto the surface of a sensi
tized Celluloid sheet, softening the Celluloid sheet
in a chemical solution, reproducing the surface 25
texture of the same leather lift heel in bas-relief
on said softened sheet with the elements repro

3. A method of producing a shoe heel cover 30
simulating a model heel made of leather lifts
which includes photographing a leather lift heel
surface on a sensitized face of a photographic
sheet of translucent material, softening the sheet
in a suitable chemical solution, embossing said 35
sheet to reproduce the surface texture of said

Preferably the photographic reproductions
which are responsible for the variation in color
indicated in Figure 2 and the variations in sur
face indicated in Figure 3 are made from the
same subject and to the same scale and, as a re
50 sult, the relation between the variations in color
and variations in surface on the finished product
will correspond to the relations on the original
model.
I am aware that it has been proposed hereto
55 fore to groove a wooden heel in simulation of the
lines between successive leather lifts and to cover
the grooved heel with a sheet or material pressed
into the grooves, but such steps produce a finished
crevice which is unduly large and lacking in the
pressed reproductions being in register with each
other to duplicate the appearance produced by
the layers of separately formed lifts in the origi
nal heel.
5. A covering for a shoe heel comprising a
sheet of flexible material bearing a photographic
reproduction of the coloring and marking of a
given leather lift heel, and having separately im
pressed therein, while softened from its normal
condition of hardness, a bas-relief design repro

I am aware also that it has been proposed here

an al1-over relief design in solid color. Heels of

so as to duplicate the color and surface texture
relation of said leather lift heel.
