IM- PROVEMENTS IN THE MANUFACTURE OF NAILS OR SPIKES, AND IN MACHINERY CONNECTED THEREWITH
Year: 1874

page_text: LETTERS PATENT to John Summers, of the Globe Iron Works,
Stalybridge, in the County of Chester, for the Invention of "IM-
PROVEMENTS IN THE MANUFACTURE OF NAILS OR SPIKES, AND IN MACHINERY
CONNECTED THEREWITH."
"
PROVISIONAL SPECIFICATION left by the said John Summers at the
Office of the Commissioners of Patents, with his Petition, on the
21st October 1874.
I, JOHN SUMMERS, of the Globe Iron Works, Stalybridge, in the
County of Chester, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MANUFACTURE OF NAILS OR SPIKES, AND IN MACHINERY
CONNECTED THEREWITH," to be as follows:-
My Invention refers to the manufacture of what are commonly called
cut nails or spikes.
According to the usual method, as is well known, strips of metal
which are fed into the machine are turned between each successive cut.

page_text: By my Invention the said strips are fed without such turning, and the
points of the severed pieces are formed by compression between suitable
dies.
The severing dies are formed in the usual manner, but, as before
stated, the strip of metal is not turned, and as the pieces to form the
nails or spikes are successively cut off, they are rolled over so as to
present their flat sides between two discs, which squeeze the metal and
form the points. To effect this rolling over I propose to employ an
additional finger, which by rising up receives the severed piece, and by
falling, thro' the agency of a suitable cam,
effects the required rolling
over. The heading is effected in the usual manner.
In order to feed the strips of metal I propose to keep them pressed
forward on a suitable table or other guide and to cause one to be forced
forward by another, by which means each strip may be worked up close
to the end thereof.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Summers in the Great Seal Patent Office
on the 21st April 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SUMMERS, of the Globe Iron Works, Stalybridge, in the County of
Chester, send greeting.
WHEREAS Her most Gracious Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of October, in the year.
of our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Summers, Her special license,
that I, the said John Summers, my executors, administrators, and
assigns, or such others. as I, the said John Summers, my executors,
administrators, and assigns, should at any time agree with, and no,
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, usc, exercise, and
vend; within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
THE MANUFACTURE OF NAILS OR SPIKES," upon the condition, amongst

page_text: to advance towards and to retreat from the part 5, these motions being
in ordinary use, and the said finger 6 is carried by a block 16 mounted
on the shaft 14.
The method of mounting the shaft 14 upon the centres is, for the
purposes of my Invention, varied, as will be seen more clearly by
reference to the enlarged detached view, Fig. 4. By this it will be seen
that the ends of the shaft 14 instead of being formed with circular
apertures are provided with slots 17 in which the centre pins 15 are
situate, and the said shaft may therefore be moved bodily upward and
downward, while it is also free to vibrate on its centre.
Upon the shaft 1 is a cam 18 (shewn by the dotted line) which by
means of a rod 19 is capable of acting upon a lever 20 mounted on the
shaft 21, which also carries two other levers 22, their outward ends
resting upon the shaft 14, beneath which are two springs 23 which tend
to press the said shaft upward, and which therefore, through the
levers 20, 22, keep the latter in contact with the rod 19, and that rod
(supported by a suitable guide) with the cam 18, according to the
positions of the parts shown in the Drawing, the feed is about to take
place and a piece of metal to be severed. When this has been effected
the said severed portion is brought to the part 5, but in this instance
against the projection 8 thereof, and the cam 11 then allows the spring 30
to draw the rod 12 upward, and by means of the lever 13 turn the
shaft 14 upon its centre, whereby the finger 6 will be caused to press
ngainst and hold the said severed portion by means of its recessed end 9.
This having been effected, the larger radius of the cam 18 will act upon
the rod 19, whereby the lever 20 will be forced downward and with it
the two levers 22, the outward ends of which acting against the shaft 14
will force it bodily downward, such motion being allowed by the centro.
pins 15 being situate in the slots 17. This downward movement of the
shaft 14 also conveys the finger 6 downward, and as this is done while
it is pressing upon the severed metal, it rolls it over and places it with
its broadest face against the recessed portion 5* of the part 5. By the
usual motion the clamp 7 and flattener 10 now move forward, the latter
however (as before explained) being formed so as to project beyond the
former, and it therefore acts a bammer and flattens the end of the
severed metal so as to form a point, which may be flat in shape or of
other form, and while the nail is thus held the heading is effected as
usual.

page_text: The finger 6 having performed its required office is allowed to turn
back in the ordinary manner, and is again moved upward by the
springs 23 ready for another operation. A nail or spike has thus been
made, and according to the usual method the strip of metal would be
turned over for another cut, but according to my Invention it is pushed
forward without such turning, the point being formed by the hammer 10
as above

The strip of metal to be operated upon may be placed in the usual
holder and fed forward by hand or by any suitable mechanical
mcans.
Having thus described and ascertained the nature of my said In-
vention, and the manner in which the same is to be performed, I desiro
it to be understood that I claim as secured to me under the above in part
recited Letters Patent, and for the purposes above set forth,-
Firstly. The use of the upward and downward motions of the finger
for rolling over the severed portion of metal.
Secondly. The use of the part 10 acting as a hammer for forming
the point of the nail or spike.
In witness whereof, I, the said John Summer, have hereunto set
my hand and seal, this Twentieth day of April, in the year of our
Lord One thousand eight hundred and seventy-five.
