Improvements in Nails..
I, SAMUEL HENRY CROCKER of 31 Furnival Street, London, Engineer, do'
hereby declare the nature of this invention to be as follows:-
This invention relates to an improved construction of nail, and has for its object
to provide a nail which will be inexpensive in manufacture, and will afford a better
grip of the material into which it is driven, at the same time requiring only a small
displacement.
In carrying out my invention a blank of sheet metal is formed tapering to the
extremity, or cut to a point of the required degree of sharpness. This blank of
sheet metal is then formed into the nail by bending it longitudinally.
According to one form the blank is bent down along its centre, making the nail
of V shape in cross section. On forcing the nail into the wood or other material a
large surface is provided against which the material will bear, so that the nail will
bite firmly. Owing to the small oross sectional area of the nail a very small
amount of the material is displaced in proportion to the surface bearing against the
material or substance through which it passes, thus reducing the danger of splitting
such a substance as wood.
In another form of nail, the blank may be bent into semi-circular shape in
section, or form a larger segment of a circle. The blank may also be beut so as to
form in section three or more sides, and into any other shape which will give a
large surface with small displacement. When a head is required it may be formed
by enlarging the upper end of the blank, and bending it over at an angle. The
sides of the blank may be stamped or cut in the form of teeth to assist the Rail in
easily penetrating any substance or material into which it is driven. The enlarged
end of the blank to form the head may also be cut at one or more points and the
parts bent over. This nail is formed from sheet metal, the tools cutting the blank
and bending the same as required.

I, SAMUEL HENRY CROCKER of 31, Furnival Street, London, Engineer, 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 an improved construction of nail, and has for its object
to provide a nail which will be inexpensive in manufacture, and will afford a better
grip of the material into which it is driven, at the same time requiring only'a
small displacement.
In carrying out my invention a blank of sheet metal is formed tapering to the

page_text: extremity, or cut to a point of the required degree of sharpness. This blank of
sheet metal is then formed into the nail by bending it longitudinally.
According to one form the blank is bent down along its centre, making the nail
of shape in cross section. On forcing the nail into the wood or other material a
large surface is provided against which the material will bear, so that the nail will
bite firmly. Owing to the small cross sectional area of the nail a very small
amount of the material is displaced in proportion to the surface bearing against the
material or substance through which it passes, thus reducing the danger of splitting
such a substance as wood.
In another form of nail, the blank may be bent into semi-circular shape in
section, or form a larger segment of a circle. The blank may also be bent so as
to form in section three or more sides, and into any other shape which will give a
large surface with small displacement. When a head is required it may be formed
by enlarging the upper end of the blank, and bending it over at an angle. The
sides of the blank may be stamped or cut in the form of teeth to assist the nail in
easily penetrating any substance or material into which it is driven. The enlarged
end of the blank to form the head may also be cut at one or more points and the
parts bent over. The nail is formed from sheet metal, the tools cutting the blank
and bending the same as required.
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet of drawings, in which Fig. 1 shows a blank from which the
nail is formed, Fig. 2 is a plan of the same, Figs. 3 and 4 are similar views of the
completed nail. Figs. 5 and 6 show another form of blank, and Figs. 7 and 8 show
the nail formed from this blank. Figs. 9 and 10 are an elevation and plan of a
third form of blank bent into the nail shown in Figs. 11 and 12. Figs. 13, 14
and 15, are further modifications in the cross section, and Fig. 16 shows a blank
with serrated or toothed edges.
According to Figs. 1 to 4, the nail is formed from a plain strip A of sheet metal
tapering almost to a point at one end. This is doubled longitudinally at the centre
so as to form the two sides A' which as shown in Figs. 3 and 4 form a nail of V shape
in cross section. This form is suitable for small nails where no head is required,
the cross section giving sufficient strength and rigidity. As shown in Figs. 5 and 6
the upper end of the blank A is formed with the extension a. On doubling the
blank as shown in Figs. 7 and 8 to form two sides A' the extension a is bent down
so as to form a flange at the desired point. A head is thus made to receive the
blow. As shown in Figs. 9 and 10 a notch a' is formed at the top dividing the
nail at the centre and forming the extensious a².
As shown in Figs. 11 and 12 the head a' is formed by bending down the
extensions internally, so that there are no projections beyond the sides.
According to Figs. 13 and 14 A2 is of semicircular or curved form in cross
section. This curve or channel may extend to the top or may be bent or pressed
out from a short distance below the upper extremity, the upper end being flat. In
the cross section shown in Fig. 15 the nail is formed with the flanges A³ at the
sides. The central portion instead of being angular may be curved or channelled.
The nail instead of tapering from the top as shown may be formed with parallel
sides for a part of its length, the lower end of the nail being pointed, or any other
shaped blank may be employed, which will serve the same purpose.
According to Fig. 16, the blank A is formed with serrated edges or teeth a³ of
ratchet shape.
These teeth may be stamped on one or both sides of the blank
which is afterwards bent in the manner before described to form the nail.
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.―
(1.) A new or improved nail formed from a blank of sheet metal,, bent
longitudinally, substantially as described and for the purposes specified..:

shown in Figs. 1, to 4 of the accompanying drawings and for the purposes
specified.
(3.) An improved nail, formed from a pointed blank of sheet metal having an
extension at the top, bent longitudinally, making a V shaped cross section, the
extensions being bent over to form a head substantially as described and shown in
Figs. 5 to 12 of the drawings, and for the purposes specified.
(4.) An improved nail formed from a pointed blank of sheet metal, bent
longitudinally into a curved cross section, substantially as shown in Figs. 13 and 14
and for the purposes specified.
(5.) An improved nail, formed from a blank of sheet metal, bent longitudinally
to form three or more sides, substantially as described and for the purposes
specified.
