Improvements in and Relating to the Manufacture of Lacing Hooks
for Shoes, and more Particularly to Providing Such with
a Protective Covering.
I, WILLIAM HENRY SMIDT, residing at Number 121, Liberty Street, in the City,
County, and State of New York, one of the United States of America, 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 invention relates to the manufacture of lacing-hooks for shoes, and it
consists in the method of protecting the hook and its shank against wear; and the
invention further consists in a lacing-hook for shoes, having its parts most exposed
to wear covered by a protective covering of a pyroxyline or cellulose compound,
or their equivalent.
Prior to my invention it has been customary either to dip the lacing-hooks for
shoes in rubber, or japan the same, but it is a well known fact that either covering
or coating is not a durable one, the rubber or japan rapidly wearing away and
leaving exposed the unsightly brass book. The object of my invention is to avoid
this by providing those parts most exposed to view with a durable covering, and to
this end I preferably use a pyroxyline or cellulose compound, as these can be applied
while in a plastic state and firmly united to the metal of the hook and afterwards
hardened and if desired polished.
Referring to the drawings A, indicates the hook proper: a, its shank; and C, the
eyelet for securing the hook to the shoe. The hook and its shank are covered with
a pyroxyline, or equivalent composition, B, which may be applied, while in a.plastic
state, in successive layers, the hook portion, A, being completely enveloped by the
composition and serves as a binder to the covering of the shank, a, which shank is
preferably covered on the outside only.
When the composition has been built up to a sufficient thickness and formed to
the shape desired, or approximately so, the covered portions are subjected to
pressure, preferably hydraulic pressure, to firmly unite the successive layers
to one another, and to the hook and its shank.
Various methods may be employed to more firmly attach the protective covering
to the hook.
According to one modification I form an eyelet, a², on the hook portion, A,
that projects vertically therefrom, as shown in Figures 14, and, 24, which show
respectively, a lacing-hook provided with the described eyelet before the covering
is applied, and such a hook in sectional elevation after the covering has been
applied.
•
The underside of the hook portion, A, is perfectly straight so as to permit of
the application of the proper tool to form the eyelet thereon in the usual manner,
so that the said eyelet or upset portion, a², will project above the hook, A, which

page_text: is then covered with the pyroxyline or cellulose composition to completely envelop
the hook, A, and eyelet, a², and then subjected to pressure, whereby the eyelet
will be upset in the composition, as shown in Figure 24, and being firmly embedded
therein form a secure anchorage of the enveloping material and binding the same
more firmly to the hook.
According to another modification, the hook may be provided with a central
opening, a³, or with peripheral notches, b, or with openings, c, within the
periphery of the hook, and said notches, b, and openings, c, may be used in
conjunction with the central opening, a³, as shown in Figures 8 to 12, inclusive, in
which―
Figure 8, shows in elevation the lacing hook with its protective covering;
Figure 9, is a vertical section thereof, and
Figures 10 to 12, are top plan views.
It will be readily comprehended that when the protective material is applied to
the hook and subjected to pressure, it will embed itself into the central
opening, as, or into said opening and the peripheral notches, b, or the openings, c,
according as either is made use of, and form a secure anchorage for the said pro-
tective material.
Other means may be adopted to bind the protective material to the metal of the
hook that will readily suggest themselves to the skilled artisan, as for instance,
tongues or prongs may be stamped out of the metal and caused to project there-
from, and when embedded in the protective material, such tongues or prongs may
be upset in the material by pressure, or peripheral teeth may be formed on the
hook, A, and bent at right angles thereto.
I wish it understood: Firstly-that I do not claim broadly a lacing-hook pro-
vided with a protective coating, as I am well aware that such has heretofore been
provided, but as herein before stated, this has simply been a thin coating produced
by japanning or rubber dipping, which speedily wears away;
Secondly that I do not wish to limit myself to any particular or specific means
for uniting the protective material with the hook and its shank, as I have clearly
shown that these means may be greatly varied.
Thirdly I would have it understood that any material may be employed for
covering a lacing-hook for the purposes stated, that is adapted to be rendered
sufficiently plastic to be united with the metal of the hook by pressure and that
will afterwards harden, or that can afterwards be hardened, and that is not readily
affected by atmospheric influences, or liable to crack or fissure and peal off.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
First The mode of covering lacing-hooks, or such hooks and their shanks,
with a protective material, such as set forth in the manner substantially as
herein before described and as shown in the accompanying drawings, Figs. 14, 2ª,
and 8 to 12.
Second: A lacing-hook having its exposed parts covered with a protective
material such as set forth, substantially as hereinbefore described and as shown in
the accompanying drawings.
Third A lacing-hook, having such exposed parts thereof as referred to, covered
or enveloped with a pyroxyline or cellulose compound, as described.
