The invention relates to shoe heels to which

The invention consists in means and

applied to the heel proper, and it has been sug

the same.
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
ure 2 but modified by the block shown in Figure 3.
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

nessses as required to produce the desired con
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
,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
face by photographing or by handicraft and` the
design so produced may be photographed directly

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.

I am aware also that it has been proposed here

so as to duplicate the color and surface texture
