COMPLETE SPECIFICATION.
Improvements in the Manufacture of Nails.
We, ARTHUR EDMUND GORSE, GEORGE AUGUSTUS PROBERT and JOHN
HENRY GREEN all of The Tower Manufacturing Company, of Bromsgrove, in
the County of Worcester, Nail Manufacturers, do hereby declare the nature of our
said invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
Our invention has for its object improvements in the manufacture of nails which
has particular reference to that class of nails such for instance as "hob nails,"
which have very large heads in proportion to the size of the shanks or points. In
the manufacture of such like nails by machinery considerable difficulty is experienced
in obtaining a sufficient amount of material to form and make large heads, but by
our invention this difficulty is overcome.
In order that our invention may be clearly understood and more easily carried
into practical effect we have appended hereunto a sheet of drawings showing how
we proceed with the said manufacture. It will be understood that most ordinary
nail machines may be adapted to the said manufacture, especially such as have a
feed motion and an after provision for forming the heads on one side after the
blanks or partly formed nails have been detached from the strips our present
invention being for the purpose of preventing waste and for heading all the nails
on one side only of the machine which we prefer, though we head from both sides
with a double headed machine.
Figure 1, shows a strip of prepared or rolled metal A such as steel of such a
section as is suitable for our purpose.
Figure 2 shows a sectional view of the said strip A with the cutting tools adapted
to the same.
Figure 3 is a similar view to Figure 2 but showing a strip A' of different section
with the cutting tools adapted thereto.
Figures 4 and 5 are cross section and side elevation of the blanks as cut from
the strip A Figures 1 and 2 previous to heading.
Figures 6 and 7 are cross section and side elevation of the blanks as cut from the
strip A as seen in section at Figure 3.
Figure 8 shows another alternative section A2 which may be used without turning
over as hereafter explained.
We roll or make such like strips as A and A' with either a flange or enlargement a³
at one edge on the upper side and a flange or enlargement a at the opposite edge
and upon the opposite side or there may be a double enlargement as shown at
Figure 3. We then place these strips in a nail machine having a set of cutters B
and E set diagonally to the line of the strip A or A' which angle may be varied to
the particular size of nails being made. When one cut has been made on the
line 22 the strip is turned over upon the undercutter or holster E so as to bring
the enlargement a³ to the same position as a now occupies when the cut 3 is
accomplished, but this cut only extends from a³ to a thus leaving an enlargement
at one end only as per several blanks Figures 4 and 5 or with a double
enlargement as per Figures 6 and 7. By thus reversing the strips at each cut the
heads are all kept to the same side of the machine which we prefer so as to fall
into position for the second or heading operation and there is absolutely no waste
of metal except from the first cut and the tail end piece. It will however be
obvious that by having a machine with a heading motion ou each or both sides that

page_text: we may avoid the necessity of turning the strips upside down by simply moving the
strip to a diagonal line from the line of the cutters on each side but in the caso of
the particular strip A shown by Figures 1 and 2 the two ribs would be placed as
shown by A Figure 8 and the cuttera 13 and E will also be modified as there
shown by Figure 8.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed declare that what we
claim is:-
1st. The improvements in the manufacture of nails of the kind specified with
large heads consisting of such like rolled strips as A and A' cut on the inclination
with the strips turned bottoin to top after each shearing operation so as to produce
such like blanks as K and K' which are afterwards headed on one side of the
machine only whother left or right and substantially as herein set forth and shown
upon the drawings.
2nd. The improvements in the manufacture of nails of the kind specified with
large heads from sections such as A' and A cut on diagonal lines by moving the
strip to the right and left without reversing it, the nails being headed by a header
on each side of the machine, substantially as herein set forth and shown.
Dated this 26th day of February 1896.
