Improvements in Metallic Staples for Boots and Shoes, and the
Method of Making the same
I PITER AMABLE COLI AI, of No 102 South Street, in the City of Boston,
in the County of Siffolk and State of Massachusetts, 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
-
This invention relates to staples employed for securing together the parts of a
boot or shoe bottom, and particularly to staples which are made from a continuous
wire and driven by an organized sole-fastening machine
The object of the invention is, first, to enable a staple of this class to be driven
into the boot or shoe bottom without liability of glancing on deviating from its
proper course while being driven, and secondly, to prevent the arms or prongs of
the staple from working their way inwardly into the interior of the boot or shoe in
case the neck of the staple connecting said prongs becomes worn away so that the
prongs are disconnected
lo these ends the invention consists in the improved staple and the improved
method of making the same which I will now proceed to describe and claim
Of the accompanying drawings forming a part of this Specification,-
Figure 1 represents a plan view of a piece of wire showing the improved method
of cutting the same into staple lengths
Figure 2 represents a perspective view of a completed staple embodying the
improvement
Figure 3 represents a view of a piece of wire showing the ordinary method of
cutting the saine into staple blanks
Ihe same letters of reference indicate the same parts in all the figures
In the drawings—
a represents a piece of wire from which a sole-fastening staple b may be made
I he wire is supplied in coils to a machine organized to cut the wire into lengths
or blanks, bend said blanks into staple form, and drive the staples into the work
A suitable machine for this purpose is shown in Letters Patent of the United
States No 493,910, dated March 21, 1893
In said machine, cutters are employed which sever the wire diagonally on the
hne a a (Figure 3) and thus form a blank sharply pointed at its end> A stiple
made from said blank is objectionable, first, because the sharp points of the prongs
are liable to catch on the sides of the holes pricl ed for their reception in the stock
and thus cause the prongs to be bent or deflected from the proper course when
being diven and secondly, because the gradually tapered sides of the prongs do
not offer sufficient resistance to prevent the piongs from working then way
inwardly into the interior of the boot or shoe in case the neck or head of the
staple becomes worn through so that the prongs are disconnected
I overcome these objections by cutting the wire as indicated in Figure 1, so as
to form a neck or head portion and blunt faces e e on the ends of blanks and
shoulders e¹ e¹ on the sides thereof, as shown in Figure 2
The blunt ends cannot engage the sides of the holes in the stock, and therefore
prevent liability of the deflection of the prongs when they are being duiven
The shoulders e¹ el give the prongs sufficient resistance or bearing on the stock
into which the prongs are driven to prevent liability of the prongs working inward
in case of the weaning away of the head or neck of the staple

page_text: In forming the staple, the blank is first cut from the wie, said blank having
the shoulders e e¹ and the blunt points ee The blank is next bent at a point
between the shoulders to form the staple, then preferably one of the prongs is bent,
so that both prongs shall occupy the same plane (see Figure 2)
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 18
1 A staple fastener for boots and shoes comprising in its construction a neck or
head, prongs arranged to lie in the same plane and provided with tapering
extremities and blunt ends, and shoulders upon said prongs between the head and
ends and at a distance from the ends approximately equal to the length of the
taper, substantially as and for the purpose described
2 1 he described improvement in the method of making staples, the same con-
sisting in so cutting the wire from which the staples are made as to form blunt
faces at the ends of the blank and shoulders on the sides thereof, the cut which
forms a blunt face forming a shoulder on the contiguous staple, bending the wire
at a point between the shoulders to form the staple, and then bonding one prong to
make it occupy the same plane as the other prong, substantially as and for the
purpose described
