COMPLETE SPECIFICATION.
Improvements in Nails for Boots, Shoes, and the like.
We, ALEXANDER FEARN MUNRO, of No. 64 High Street, Boston, in the County
of Suffolk, and WALDO SHERMAN COLE, of Maple Street, Kingston, in the
County of Plymouth, both in the State of Massachusetts, United States of
America, Tack Manufacturers, do hereby declare the nature of this invention and
in what mauner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
Our invention relates more particularly to that class of shoe nails that are used
for nailing heels, and is adapted for "blind nailing." The invention consists in
the peculiar formation of the nail which will be best understood by reference to
the Specification and drawings.
The objects being to so form the head that it will firmly secure the top lift, and
to so form the point that it will readily penetrate and form a broad, well anchored
clinch.
These objects we attain by the construction shown in the accompanying drawings
in which
Figures 1 and 2 are elevations of the nail complete.
Figure 3 is a cross section taken on line - of Figure 2.
Figure 4 is a cross section taken on line y-y of Figure 2.
Figure 5 shows in section a heel and one of our nails.
Figure 6 is a section of a portion of a heel showing the head and a part of one
of our nails.
Our nail is shown complete in Figures 1 and 2. The head of which is made with
a fillet or collar B, formed in the usual manner; immediately above this fillet B, the
body is nicked as shown at bb, (Figure 2); above the nicks b, b, the part is flattened
so as to form a comparatively broad, dove-tail head H, which formation together
with the nicks b, b will constitute a reliable "hold," for the top lift.
The point P of our nail is formed with a comparatively Hat, inclined side D',
(Figures 1 and 2); the other side D, of the point P having an ovato-oblong
surface as indicated at K (Figure 2) and also by the cross-section, Figures 3
and 4.
The object of swaging the point as described and shown, is to obtain a broad
flat surface near the extreme point as illustrated at t, t (Figure 1), and also to
have that part strong so that when the clinch is formed as shown in Figure 5, a
broad flat surface is presented to the leather as a buttress and a firm anchorage is
secured, the clinched part of the nail being in itself a large cross section insteal of
a mere thin, easily bent strip.
A peculiar feature of our nail, is, that its penetrating edge is wedge-shaped,
the point of the wedge being in the central longitudinal plane of the body of the
nail so that the point would have no tendency to turn and clinch were it not that
the two sides of the point are different as shown in the drawings, that is, one side
consists of a plain surface, while the other is like the back of a spoon.
Ilaving now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. As an improved article of manufacture, a nail having a point bevelled or
incliued on one side and formed with a broad, rounded extremity which terminates

page_text: in the axis of the nail, and the opposite side of the point rounded or spoon backed,
substantially as described.
2. As an improved article of manufacture, a nail having a point bevelled or
inclined on one side and formed with a broad, rounded extremity which terminates
in the axis of the nail, the opposite side of the point being rounded or spoon backed
and a head of dove-tail form of less thickness than the diameter of the nail and
with nicks below the head, substantially as described.
3. As an improved article of manufacture, a nail having a point bevelled or
inclined on one side and formed with a broad, rounded extremity which terminates
in the axis of the nail, the opposite side of the point being rounded or spoon backed
and a head of dove-tail form with nicks below the head and a collar below the
nicks, substantially as described.
