page_text: LETTERS PATENT to John Summers, of the Globe Iron Works,
Stalybridge, in the County of Chester, for the Invention of "Iμ-
PROVEMENTS IN THE MANUFACTURE OF NAILS OR SPIKES
PROVEMENTS IN THE ManufacTURE OF NAILS OR SPIKES
PROVISIONAL SPECIFICATION left by the said John Summers at the
Office of the Commissioners of Patents, with his Petition, on the
13th April 1875.
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," to be as
follows:-
My Invention refers to what are commonly called cut nails or spikes,
and consists in an arrangement whereby I am enabled to produce an
article of superior shape to that now manufactured in cut nail
machines.
I still propose to produce the articles from strips of metal, which may
be turned once between cach cut, as now practised, but while the

page_text: severed portion is held in the dies I cause a punch or hammer to
advance and act upon the end thereof, whereby a flattened or other
shaped point is produced. The gauge of metal I use is such that the
section of the severed portion is greatest in a vertical direction, and the
width of the siad sovered portion is regulated accordingly. The heading
is performed in the usual manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Summers in the Great Seal Patent Office on
the 13th October 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 Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of April, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Ier reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Summers, Ier 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, use, 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 others) that I, the said
John Summers, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said In-
vention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Scal Patent Office within six
calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said John Summers, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and

page_text: by the following statement and accompanying Drawings, that is to
say
-
My Invention refers to what are commonly called out nails or spikes,
and consists in an arrangement whereby I am enabled to produce an
article of superior shape to that now ordinarily manufactured in cut nail
machines.
Under a Patent granted to me dated Twenty-first October One thou-
sand cight hundred and seventy-four, No. 3630, I described a method of
making nails or spikes in cut nail machines, according to which the
strip of metal fed to the machine was not turned over between each cut,
and the point was formed by a hammer which flattened the end of tho
severod portion.
According to my present Invention I still use the aforesaid hammer,
but I do not roll the severed portion of metal over as described in the
Specification of my Patent aforesaid, but obtain the same result by
using a gauge of metal, or such a feed as will cause the section of the
said severed portion to be greatest in a vertical direction; whereas,
according to my former Invention, aforesaid, and according to the
ordinary method of making cut nails the section of the severed portion
of metal is the greatest in a horizontal direction; but in the Specifi-
cation of my former Patent, aforesaid, I described the use of a finger for
rolling over the severed metal so as to present its flat side to the action
of the hammer.
In order fully to explain the principle of my Invention I refer to the
diagrams, Fig. 1 and 2, the former being a top view of a strip of metal
as it is fed to the machine, and the latter a section thereof. It 18
obvious that if this strip of metal be severed at the dotted line a, a, the
greatest thickness will be presented to the holding dies in a horizontal
direction, because the distance from a, a, to 6 is greater than the
sectional thickness represented at Fig. 2; but if the severance take
place as at the dotted line c, c, then the severed portion will present its
smaller thickness to the holding dies and its greater sectional area will
extend vertically. This may be accomplished in two ways; the gauge
of metal used may be such that with a given extent of feed the desired
result will be attained, or with a given gauge of metal the extent of
feed may be increased or diminished.
In carrying out my Invention I use the machine as described in my

page_text: former Specification, aforesaid, excepting that the cam 18 thereof and
the levers and other parts upon which it operates for rolling over the
severed metal are dispensed with, as is also the notch 9 on the finger 6,
and the cut metal is therefore held by the said finger in the ordinary
manner. The hammer 10, which is reproduced from my former Specifi-
cation at Fig. 3 of the accompanying Drawing, now advances and forms
the point upon the flat side of the metal. Before another cut is made
the strip of metal is turned over as in the ordinary process of making
nails, and thus the operation continues, the heading being performed as
usual.
Having thus described and ascertained the nature of my said In-
vention and the manner in which the same is to be performed, I desire
it to be understood that I claim as secured to me under the above in
part recited Letters Patent, the production of cut nails or spikes by
causing the metal to be severed so that the section of the severed
portion is greatest in a vertical direction.
$
In witness whereof, I, the said John Summers, have hereunto set
my hand and seal, this Twelfth day of October, in the year of
our Lord One thousand eight hundred and seventy-five.
