PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Nails.
I, ALFRED HENRY WILLIAMS, of The Green, Wishaw, in the County of
Lanark, North Britain, Ironmaster, do hereby declare the nature of this invention
to be as follows, that is to say :-
My said invention relates to nails such as are formed by being cut transversely
from steel or iron strips or bands which are of tapering thickness across their
width; and my invention consists in rolling the strips or bands with ratchet-like
grooves, so that when the nails are cut therefrom they have notched sides so as to be to
some extent barbed, which formation gives them an increased holding power. The
rolls are simply shaped so as to be counterparts of the grooves intended to be
produced.

Improvements in the Manufacture of Nails.
I, ALFRED HENRY WILLIAMS, of The Green, Wishaw, in the County of
Lanark, North Britain, Ironmaster, 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, that is to say:-
My said invention relates to nails such as are formed by being cut transversely
from metal strips or hands which are of tapering thickness across their width;
and my invention consists in rolling the strips or bands with ratchet-like grooves,
so that when nails are cut therefrom they have notched sides so as to be to
some extent barbed, which formation gives them an increased holding power. The
rolls are simply shaped so as to be counterparts of the grooves intended to be
produced.
And in order that my said invention and the manner of performing the same
may be properly understood, I hereunto append a sheet of explanatory drawings,
to be hereinafter referred to in particularly describing my improvements.
Figures, 1, and 2, of the drawings are elevations of rolls, as made according
to one modification.
Figure, 3, is a section of the bar to be rolled.
Figure, 4, is an enlarged cross section of the rolled strip, from which the nails
are to be cut.
Figure, 5, is an elevation, and Figure, 6, a transverse vertical section of rolls,
made according to a second modification.
Figure, 7, is an enlarged view of a large nail or spike made from a rod rolled in
rolls such as are shown in Figures, 5, and 6.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.

page_text: The bar, A, Figure, 3, is passed successively through the passes of the pair of
rolls, B, B1, C, C1, D, DI, E, E 1. Thereafter it is passed between finishing
rolls, J, and K, from which it issues formed with ratchet-like grooves, L, so that
when the nails are cut therefrom they may have barbed sides, this formation giving
them an increased holding power. The upper roll parts, B, C, and D, are plain
and cylindrical whilst the lower roll parts, B1, C1, and D1, are formed with
indentations or recesses of the shapes shown for gradually reducing the strip, A.
The upper and lower roll parts, E, E 1, are formed with equal shallow recesses
combining to impart the desired transversely tapering form to the metal strip.
The finishing rolls, J, and K, are formed with grooves which are counterparts of
the grooves, L, required to be produced in the strip, A; these grooves being
formed circumferentially on the rolls.
In Figure, 5, rolls are shown by which bar or rods can be rolled of round
section, but with two sides notched or barbed in a similar manner to the strip, A.
The bar is entered first through the pass, M, of the rolls, the grooves of which are
smooth, and thereafter through the pass, N, of the rolls, the grooves of which are
made with ratchet-like notches shaped to impart to the rod or bar the barbed
form desired to be produced. The rod or bar issues from the roll parts, N, notched
or barbed as shown in Figure, 7, the head being subsequently formed on each nail
or spike.
The grooves of the rolls, M, N, may be shaped to make the rod or bar of an
oval, square or polygonal form.
The invention is applicable for making nails of steel, iron, copper, or other
suitable metal.
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
1 claim is: :―
In the manufacture of nails the rolling of the metal strips, bars, or rods for
forming the nails, with ratchet-like grooves substantially as and for the purposes
hereinbefore described.
