SHOE 'HEEL
Peter B. Sullivan, Randolph, Mass.
Application July 13, 1937, Serial No. 153,315
8 Claims.
This invention relates to the heel structures of
shoes and is more especially concerned with the
high heels of women’s shoes.
Heels of this type usually consist of a wood
5 heel or heel body covered with some sheet ma
terial consistent with the style and general make
up of the shoe and equipped with a leather or
rubber top lift. Since practically all of the wear
on the heel comes on this top lift, it is necessary
10 after a time to renew this member. Such re
newal is very liable to split the wood heel and
thus to ruin it. This is particularly true if the
heel is of the so-called “spike” type, since such
a heel has a very small lower end to. which the
15 top lift is secured.
The present invention deals with the problem
presented by these conditions, and it aims to de
vise a heel structure with which the renewal of
the top lift can be effected quickly, economically,
20 and with no danger of injuring the body of the
heel. While the invention is particularly useful
as applied to wood‘ heels, it can also be used
to advantage on other types of heels.
The nature of the invention will be readily
25 understood from the following description when
read in connection with the accompanying draw
ing, and the novel features will be particularly
pointed out in the appended claims.
In the drawing,
30
Figs. 1, 2 and 3 are perspective views, respec
tively, of a wood heel, a top lift securing plate,
and a top lift assembly, all embodying features
of this invention;
Fig. 4 is a vertical, sectional view through the
35 lower part of the heel shown in Fig. l, illustrat
ing the manner in which the plate preferably is
mounted;
Fig. 5 is a vertical, sectional view through the
assembly shown in Fig. 3;
40
Fig. 6 is a View, partly in side elevation and
partly in vertical section, showing the complete
heel structure;
‘
Fig. 7 is a view similar to Fig. 6 showing the in
vention applied to a different form of heel;
45
Fig. 8 is a plan view of the top lift structure
shown in Fig. 7 ; and
, Fig. 9 is a view similar to Fig. 6 illustrating a
modi?cation.
Referring ?rst to Figs. 1,. 2, 3 and 6, the con
50 struction there shown comprises a wood heel 2.
Secured to the lower face of this heel is a top
lift securing plate 3 in which are provided two
slots 4-6, one behind the other. The topv lift
5 has a metal plate 6 secured to its upper face
55 and is provided with two lugs Lil which pro
(oi. 12-147)
ject upwardly through the slots 4-4. In each
of these lugs a hole 9, Fig. 3, is drilled, and the two
holes are alined with each other and with a hole
ll drilled horizontally in the heel just above the
plate 3, this hole opening on to the breast sur 5
face of the heel. A pin 8 is pushed through
these holes and thus secures the top lift as
sembly releasably in its operative position. Pref
erably this pin is exteriorly roughened so that
it offers a substantial degree of resistance to pull
ing it out of place and thus avoids any danger of
its working out of its operative position acci
dentally. No attempt has been made to show the
covering for the heel since the nature of the cov
ering used is immaterial so far as the present
invention is concerned.
When the top lift 5 has become worn sui?cient
1y to make its renewal desirable, it is merely
necessary to purchase a new pair of top lifts,
preferably with the plates 6 secured to them,
and then to remove the worn top lift on each
shoe by withdrawing the pin 8 and simply pull
ing the top lift assembly off the heel. The new
top lift is put on the heel in place of the old
one and is secured in this position by reinsert 25
ing the pin 8.
In order to. avoid the use of metal fasteners
in securing the plate 3' to the heel 2 and thus
eliminating the necessity for weakening the heel
and possibly splitting it, I prefer to make this
plate in the form of a circular disk with rough
ened edges, somewhat bulged or convex in cross
section, and to bore a very shallow hole in the
bottom of the heel to form a seat l0 adapted to
support the margin of the disk 3. Eitherat this
time, or subsequently, the bottom of the heel
also is cut away to provide spaces above the slots
4-4 into which the lugs 1-‘! can project. Pref
erably'this is accomplished by drilling an an
nular hole or groove 12 in the heel so that the
wood in the central part of the heel will not be
removed but will be left in the form of a post or
projection Id. In securing the plate in the heel,
it is merely necessary to place it on its seat In
and then to force the central portion of this plate
upwardly into substantially the plane of the
margins of the plate. This ?attens the plate into
approximately the form shown in Fig. 6, and
during this flattening process the overall diam
eter of the disk is increased, thus forcing the
edges of the disk into the circular wall of ma
terial surrounding the seat in and embedding it
in this wall.
The degree of expansion or en
largemerr‘t of the disk need not be great in order
to Secure it in the» heel with ample ?rmness for
2
2,137,816
the purposes of this invention. This arrange
ment, however, requires a very simple assem
bling process, avoids the use of metal fasten
ings, and provides a more secure fastening means
than do nails, tacks, and the like. In addition,
the parts and the method of assembly are rela
tively inexpensive. By leaving the post M in
the central part of the cavity formed in the
face of the heel, or by providing a similar post
additionally, the range of the ?attening move
ment of the disk is limited, this post acting as
a stop against which the central part of the disk
is forced.
It will be observed that the pin 8 cooperates
15 with the wood of the heel in which it is em
bedded and the lugs of the plate 6 to hold the
top lift against the bottom face of the heel.
The plate 3, however, is essential in a heel struc
ture of this character in reinforcing the bottom
20 face of the heel, positioning the lugs ‘I so as to
center the top lift accurately and holding the
lugs in such positions against the forces tending
to displace the top lift laterally, forward, or
25
backward.
The metal plate 6 may be secured to the upper
surface of the top lift 5 by providing this plate
with metal prongs or tongues, as shown in Figs.
3 and 5, these prongs being partly cut from the
material of the plate itself and being forced into
30. the upper part of the lift.
Figs. '7 and 8 show the invention in a con
venient form for application of a leather heel
or a wooden heel of larger tread dimensions.
This construction is like that shown in Figs. 1,
2, 3 and 6, except that here the metal plate 6’,
which is secured to the upper surface of the top
lift 5’, is of smaller overall dimensions than the
top lift and is set into the top lift flush with its
upper surface. In other words, the margin l5
of the top lift is left uncovered by the plate
6'. This construction is preferred in leather
heels since the presence of the edge of the plate
at the periphery of the heel would not be de
sirable. It is usually, however, more desirable
45 to have the plate edge exposed in spike heels,
Louis heels, and other very high heels, since this
metal plate protects the margins of the heel
cover where they are turned over upon the bot
tom of the wood heel 2 and cemented to this bot
50 tom surface.
When the nature of the heel 2 is such that it
should be reinforced by a dowel, the dowel pin
may be utilized to back up the metal plate 3 in
essentially the same manner that the part I4
55 backs up this plate.
However, a more conven
ient construction is to make the dowel pin of
metal integral with the metal disk or plate 3.
Such a construction is shown in Fig. 9, the dowel
pin being indicated at l6 and the metal disk or
60 plate at 18, and these two parts being integral
with each other. The disk [8 is slotted in the
same manner as is the disk 3 to receive the lugs
1-4 of the plate 6 which is secured to the top
lift 5. This heel lift is releasably locked in its
65 operative position by a pin 8 in the same manner
as in the constructions above described.
While I have herein shown and described typi-'
cal embodiments of my invention, it will be un
derstood that the invention may be embodied in
70 other forms without departing from the spirit
or scope thereof.
Having thus described my invention, what I
