HEEL AND METHOD OF COVERING THE

'This‘invention relates to the manufacture of
shoes and is-illustrated as embodied in a novel
heel and with reference 'to improvements in
covering the same.
01
Inv covering wood heels of the Louis type, it is
common practice to coat the edge portions of
the heel with pyroxylin cement and then to ap
ply a Celluloid cover, which has been activated
by~a suitable solvent, to the rear and side faces
10 of the heel, the forward projectingmargins of
the cover being inturned on and secured to the
\lateral margins of the heel breast. In view of
the fact that the leather heel-breast-covering
flap of the shoe to which the heel is attached
cannot be effectively secured to the inturned mar
gins of the Celluloid cover on the heel breast
through the use of rubber cement, which is bet
ter adapted for this purpose than pyroxylin
cemenhand in order to‘ prevent the formation
20v of ridges in. the heel breast of the finished shoe
where the heel-breast-covering ?ap overlies the
edges of’ the inturned margins of the Celluloid
cover, it is common practice totrim the inturned
margins of the cover ?ush with corresponding
25 breast edges of the heel after the’ cover has ‘dried
portions of the inturned margins‘of the cover
secured in therecesses. The inturned margins
of the cover which are secured Within the recesses
serve to counteract the above-mentioned tend
ency of the cover to pull away from the forward
The'various features of the invention will be
understood and appreciated from the following
detailed description, read in connection with the
accompanying drawing.

In the drawing,
Fig. 1 is a perspective view of an uncovered
wood heel of the Louis type having in the lateral
margins of its breast a plurality of spaced recesses
intersecting corresponding sides of the heel, the
margin of the attaching face of the heel being
provided with a plurality of recesses which termi
nate at the rim of said attaching face;

heel;
After the heel has been attached to the
shoe, the heel-breast-covering flap is secured ‘to
the breast of the heel by the use of rubber cement.
When heels are covered as above described, it
hasfbeen found that the Celluloid cover of the
?nished shoe frequently breaks away from the
sides of. the'heel along its breast edges. Such
defect maybe the result of the wearer sliding
35 ' the breast edges of the heel of the shoe along
rungs of chairs or other objects, or may be caused
by the failure of the operator properly to coat the
entire edge portions of the heel with pyroxylin
cement before attaching the Celluloid cover to
40 the heel.'
In order to overcome the above-mentioned de
feet in Celluloid-covered heels, I have provided
a heel having in each lateral margin of its breast
a plurality of shallow cover-receiving recesses
which are spaced from each other and intersect a
corresponding side of the heel. In order to
secure the activated Celluloid cover to the heel,
the operator applies a ?lm of pyroxylin cement
to the edge portions of the heel and, after apply
ing the cover to the rear and side faces of the
heel and forcing the forward projecting margins
of the cover against the lateral margins of the‘
heel breast and into the recesses formed in the‘
breast, trims the inturned margins of the cover
flush with the breast edges/of the heel, leaving
5
margins of the sides of the heel.
Fig. 4 is a section on the line IV--IV of Fig. 3,
and
Fig. 5 is a plan view showing the attaching 30
face of the heel after the top inturned margin
of the cover has been trimmed, leaving portions
of said margin secured in the recesses formed
in the margin of the attaching face.
The invention is illustrated with reference to a 35
wood heel 20 of the Louis type to which a Cellu
loid cover 22 (Fig. 4) is to be applied. The lateral
margins of the breast 24 of the heel are provided
with recesses 26, each of which intersects a cor
responding side of the heel and has a depth 40
not greater than the thickness of the cover 22.
The margin of the attaching face of the heel
is provided with a plurality of spaced recesses 28,
the outer ends of which terminate at the rim 30
45
of the attaching face 32 of the heel.
reparatory to attaching the cover 22 to the
heel, the marginal portions of the heel which are
located adjacent to the breast edges 34 and
the rim of the attaching face 32, including the
recesses 26 and 28, are

After the top margin 38 of the, cover 22 has

By providing the tabs 42, it is possible to trim
the inturned top margin'38 of the cover just,

exposing substantially the entire attaching face
of the original wood heel for heel-attaching pur
poses.

The recesses 26 and 28 are preferably cut to
