PROVISIONAL SPECIFICATION
An Improved Nail, suitable for Boots and other Purposes.
I, JOHN BLAKEY, of Lady Lane, Leeds, Yorkshire, Boot and Shoe Manufacturer,
do hereby declare the nature of this invention to be as follows:-
The object of my invention in nails is to prevent them working loose and falling
away from their place.
In making a nail according to my invention, I form one or more indents,
serrations, or shoulders on the stem of the said nail, so that after it has been driven
into position, the shoulder or shoulders absolutely prevent the nail from working loose
and falling away from its position.
I also form the outer surface of the nail head in a convex form, so that when the
nail is driven into the leather, the convex-headed nails are in a line with the curvature
of the boot sole, which is not the case where the faces of the nails are flat.
The convex headed nails can also be driven level with the leather.

COMPLETE SPECIFICATION.
An Improved Nail, suitable for Boots and other Purposes.
I, JOHN BLAKEY, of Lady Lane, Leeds, Yorkshire, Boot and Shoe 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:-
The object of my invention in nails is to prevent them working loose and falling
away from their place.
In making a nail according to my invention, I form one or more indents,
serrations, or shoulders on the stein of the said nail, so that after it has been driven
into position, the shoulder or shoulders absolutely prevent the nail from working
loose and falling away from its position.
I also form the outer surface of the nail head in a convex form, so that when the
nail is driven into the leather, the convex headed nails are in a line with the
curvature of the boot sole, which is not the case when the faces of the nails are flat.
The convex headed nails can also be driven level with the leather.
Such being the nature and object of my invention, I will now proceed to describe
the same more fully, and for that purpose make reference to the accompanying
sheet of drawings illustrative thereof, wherein Fig. 1 is an enlarged geometrical
elevation and Fig. 2 side view of my improved form of nail having on each side
thereof a projection a and a curved surface, on the outer side of the nail head, so
that when inserted into the sole of a boot, as shewn in Fig. 3, the serrations a
prevent the nail from falling away whilst the curved surface of the nail head is in a
line with the boot sole as shewn at b, and if the nail is driven "home" or flush
with the sole as shewn at c, the surface of the head is level with the leather. This
form of nail can be made by punching and stamping, or they may be moulded in
sand and cast with metal. Figs. 4 and 5 shew modified shapes of the projection a.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
Firstly. The construction of nail for boots and other purposes having indents,

page_text: serrations, or shoulders on the stem, as shewn in the drawings and for purposes
specified.
Secondly. The construction of a nail for boots and other purposes having a
convex shape of head in manner shewn and for purposes described.
Thirdly. The construction of a nail for boots and other purposes, having indents,
serrations, or shoulders on the stem, in combination with a convex form of head.
