Improvements in and relating to Rubber Heels for Shoes and Boots.
I, CARA SALSBURY FERGUSON, of 39 and 41, East Spring Street, in the City of
Columbus, County of Franklin, and State of Ohio, United States of America,
Manufacturer, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascertained
n and by the following statement:-
My invention relates to the improvement of rubber heels for shoes and boots,
and the objects of my invention are to provide an improved heel of this class
adapted to be attached to an ordinary boot or shoe heel; to so construct the
same as to insure the retention of a close and desirable contact of the rubber
with the surface of the leather heel, and to provide other improvements, the
details of construction and arrangement of which will be more fully pointed
out hereinafter.
These objects I accomplish in the manner illustrated in the accompanying
drawings, in which---
Figure 1 is a detail view in perspective of a shoe heel having my improved
attachment connected therewith. Fig. 2 is a detail view in perspective of the
Fig. 3 is a similar view in perspective of an inter-

mediate spring frame or washer which I employ in the manner hereinafter
described. Fig. 4 is a central horizontal section of the heel attachment, and.
Fig. 5 is a transverse section of the same.
Similar letters of reference refer to similar parts throughout the several views.
In carrying out my invention I cause to be molded or otherwise produced a
rubber heel section a, which, as indicated in the drawing is of a concavo-convex
form. The upper side of the rubber heel section or body is formed with a raised
marginal portion which is indicated at b, this raised portion being continuous

about the margin or outline of the heel section.
I enclose or embed in the body thereof a metallic spring frame or washer c,
which although smaller has somewhat the outline of the heel section a, and
which is normally curved or bent to correspond to the curvature of said heel
section.
As indicated at d I form at desirable points in the heel section a, openings
which as shown at e are continued through the internal spring frame c, these
openings being designed to receive the screws, nails, or other attaching devices
through the medium of which the heel section a is secured to the outer lift of
5 the usual leather heel f.
It is obvious that when the concavo-convex heel section is screwed tightly
against the leather heel surface, said heel section will thus be forced to assume
the straight or horizontal form of the leather heel lifts, and owing to the natural
tendency of said heel section to assume its normal curved form, it will be seer
0 that the tendency of the raised marginal portion b will be to cling closely to the
surface of the leather, thereby overcoming the usual tendency of rubber hee
attachments toward lifting up or separating from the leather at the edges. I

page_text: will be observed that the curved spring frame c which is embedded as described
in the rubber heel section, will assist in imparting the desired curvature to the
rubber and increase the tendency toward the latter retaining its concaved form.
Although I have described the rubber heel attachment as being so secured to
the leather heel surface as to bring the raised marginal portion b in contact
with the leather, it is obvious that said heel attachment might be inverted if so
desired.
From the construction shown and described, it will be observed that a
desirable form of rubber heel attachment is provided for boot and shoe heels,
which will at all times cling closely to the boot or shoe heel surface, and that
the usual tendency of rubber heel attachments to raise or separate from the
leather heel at the edges will be entirely obviated.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is
1. In a rubber heel attachment for boot and shoe heels, a heel section or
body a molded to a concavo-convex form and provided with a raised marginal
portion and openings therethrough, substantially as specified.
2. In a rubber heel attachment for boot and shoe heels, the combination with
an elastic heel section a molded to concavo-convex form; of a correspondingly
concaved spring metallic frame embedded within said heel section and provided
with openings registering with those of said heel section, substantially as
specified.
