Improvements in Hob Nails.
1 WILLIAM RICHARD WILCOX of the City of Pittsburgh in the County of Allegheny
and State of Pennsylvania, 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 in and by the following statement :-
My invention relates to improvements in hob nails and consists in having a supple-
mental head, separate from the nail, and provided with an aperture through said head
to receive the head of the nail, and outwardly inclined projections on the inner surface
thereof to enter and embed themselves in a shoe sole, and a flat outer wearing surface,
and a nail having a head integral therewith and corresponding in form with, to be
driven through the aperture in said supplemental head as will hereinafter appear.
To enable others to make and use my invention I will proceed to describe its
construction.
In the accompanying drawings
Fig. 1 represents the botton or sole of a boot or shoe with the hob nails driven in.
Fig. 2 is a top view of a round headed nail.
Fig. 3 is a top view of a square headed nail.
Fig. 4 is a section showing the nail inserted in the opening of the head.
Fig. 5 is a view of the nail to be driven through the opening or aperture in the
head.
In the drawings A is a supplemental head or hob of the nail and is provided with an
aperture B through which the nail passes and said aperture may be of any desired
form.
The head A may also be provided with a recess or countersink E for the reception
of an enlarged or flattened head on the nail D.
On the inner surface of the supplemental head are outwardly inclined projections or
wings C which embed themselves in the leather when the nail and the supplemental
head are driven into the sole or heel of a shoe and assist in holding the nail and
supplemental head in position on a shoe by reason of the outer inclined surface of the
projections being forced into and under the grain of the leather. D indicates the nail
proper or body portion and is provided with a head at one end integral therewith
which head corresponds in shape with the shape of the aperture B in the supple-
mental head A and when driven through said aperture into a boot or shoe sole, the
outer face or surface of the head of the nail Dis flush with the outer or wearing
surface of the supplemental head A. The body portion of the nail presents a plain
smooth surface and is slightly tapered at its driving or entering end.
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
A hob nail having a supplemental head separate from the nail, and provided with
an aperture through said head to receive the head of the nail, and outwardly inclined
projections on the inner surface thereof to enter and embed themselves in a shoe sole,
and a flat outer wearing surface, and a nail having a head integral therewith and
corresponding in form with and to be driven through the aperture in said supple-
mental head substantially as described.
