Improvements in Divided Heels for Boots and Shoes, and in
Fastening Devices for Use therewith.
I, CARL LUDWIG SCHRADER, of Brunnenstrasse No. 33, Hamburg, Germany,
Gentleman, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
The divided heels for boots and shoes hitherto employed consisting of an upper
section permanently forming a portion of the boot or shoe and of a removable lower
section inserted therein, possess the disadvantage that the means, such as screws,
pins, and nails employed for the purpose of preventing the accidental separation of
the two sections are liable to become so worn that the separation of the two sections
when desired is generally impossible.
Now this invention has reference to a fastening device adapted to act automatically
for securing together the two sections of the heel when the lower section is pushed
into position on the upper section, the said device affording absolute security against
accidental unfastening but nevertheless allowing of the easy and quick separation
of the sections when required.
In the accompanying drawings,
Fig. 1 is an underside view showing the upper section of a boot heel with one
portion of the improved fastening device applied to it.
Fig. 2 is a plan or top view of the lower section of the heel with the other
portion of the fastening device applied to it.
Figs. 3 and 4 are front elevations of the upper and the lower sections respectively
of the heel with fastening device.
Figs. 5 and 6 are sections on the lines A B and C D respectively of Fig. 1, the
lower section of the heel being partially inserted.
My improved fastening device comprises a metallic spring and a metallic plate.
The spring is bent to correspond to the form of the heel and is secured on the
lower surface of the upper section a of the heel by any suitable means. The inner
edge of the curved portion of this spring is bent downwardly to a small extent (see
Fig. 6) and the straight front part of the spring is bent downwardly at right
angles or thereabouts to form a spring-nose c. The metallic plate f is fastened on
the upper side of the lower section d of the heel and has its outer edge bent
upwardly (see Fig. 4). The arrangement is such that in order to fasten the two
sections a and d together, the upwardly bent edge of the plate is placed between
the section a and the downwardly bent edge of the spring and the section d is then
pushed home, i.e. until the straight front edge of the section d passes behind and is
Secured by, the nose c.
In order that it may be possible to separate the two sections a and d, small
notches g and are made in the nose c and the plate respectively in order that the
section d can, by means of a hooked instrument, be moved to clear the nose c after
which it can be easily drawn out.
The improved fastening is absolutely secure, since the lateral displacement of the
part d is prevented by the spring b and the plate f, which are compressed by the
weight of the person standing thereon and act as a feather and groove, whilst
longitudinal displacement of the section d is prevented by the spring-nose c.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is :
1. In a divided heel for a boot or shoe comprising two sections connected by
means of a feather and groove or equivalent contrivance a spring-nose e located at
the front of the upper section a and adapted to retain the lower section d in position
when the same has been pushed home as set forth.
2. The improved fastening device described and shown for connecting together
the sections of a divided beel in the manner set forth.
