Year: 1857

page_text: LETTERS PATENT to Abel Stokes, of Birmingham, in the County of
Warwick, Manufacturer, for the Invention of "NEW OR IMPROVED
MACHINERY TO BE USED IN THE MANUFACTURE OF NAILS, PINS, SCREWS,
AND OTHER SIMILAR ARTICLES."
:
Sealed.the 4th August 1857, and dated the 10th February 1857:
PROVISIONAL SPECIFICATION left by the said Abel Stokes at the Office
of the Commissioners of Patents, with his Petition, on the 10th February
1857.
-I, ABEL STOKES, of Birmingham, in the County of Warwick, Manufacturer,.
do hereby declare the nature of the said Invention for "NEW OR IMPROVED
MACHINERY TO BE USED IN THE MANUFACTURE OF NAILS, PINS, SCREWS, AND OTHER
SIMILAR ARTICLES," to be as follows:-.
My Invention consists of machinery, herein-after described, for holding.
pins, spikes, and similar articles, and protecting the points of the same during
the operation of forming heads on the said pins or spikes.
The spike to be operated upon is held in a pair of dies, that part of the
spike on which the head is to be formed projecting from the said dies. In
order that the spike may project to the proper distance from the dies, Iiplace a
spring bottom in one of the dies, on which said spring bottom the point of the
spike rests, the said spring bottom holding up or supporting the spike at the
required height, and preventing injury to the point when the spike is dropped:

page_text: into the dies. The heads are cast upon the spikes, pins, or screws, in the ordi-
nary way; they are then stamped and turned or finished in any other con-
venient manner. The said spring bottom consists of a plate pressed upwards
by a helical or coiled spring.
By the use of my Invention the heads are better secured than by the ordinary
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Abel Stokes in the Great Seal Patent Office on the 4th
August 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ABEL
STOKES, of Birmingham, in the County of Warwick, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of February, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Abel Stokes, Her special licence that I, the said Abel Stokes, my execu
tors, administrators, and assigns, or such others as I, the said Abel Stokes,
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 "NEW OR IMPROVED MACHINERY TO BE USED IN THE
MANUFACTURE OF NAILS, PINS, SCREWS, AND OTHER SIMILAR ARTICLES," upon the
condition (amongst others) that I, the said Abel Stokes, my executors or
administrators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
.
NOW KNOW YE, that I, the said Abel Stokes, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof, that is to say:
My Invention consist of the machinery, herein-after described, and illus-
trated in the accompanying Drawing, for holding pins, spikes, and other
"

page_text: similar articles, and protecting the points of the same during the operation of
forming heads on the said pins and other articles.
Figure 1 of the accompanying Drawing represents.in perspective a tool or
pair of dies used for holding pins, spikes, or rods on which heads are to be
formed; Figure 2 represents in elevation the two dies of which the tool
Figure 1 is constructed; Figure 3 represents a vertical section taken through
the line a, Figure 1; and Figure 4 represents a plan of the under side of the
dlies or tool.
The dies or tool represented in the Drawing is constructed according to my
Invention. The same letters indicate the same parts in the several Figures.
b, c, are two dies, connected together by the spring d. The spike or rod to be
operated upon is held between the said dies b, c, the said dies being closed
upon the said spike or rod, and made to grip it by the contracted parts b¹, c¹,
as shown in Figure 3. The top of the spike e projects above the dies b, c, and
the projecting part of the said spike e is formed into a head by the ordinary
method. The point at the bottom of the spike or rod rests upon a spring
bottom constructed in the following manner:-f is a plug, working in the
cylindrical cavity g; h is a helical or coiled spring, on which the plug f rests.
The said spring his supported by the plate i, attached to the die b. The plug
and spring bottom f hold up or support the spike e at the required height,
and prevent injury to the point when the spike is dropped into the dies and
during the formation of the head. While the spike e is held in the dies b, c,
a head is formed on the top of the said spike e; the pins or spikes when so
formed are used for making brass-headed nails in particular, but by forming
various kinds of tops upon the said spikes or pins they are applicable to other
purposes.
Figure 5 represents a spike without a head, and also other spikes made into
nails by variously formed heads being made thereon, the nails k and l having
solid heads made thereon, and the nail m having a solid head suitable for
having a brass bead cast thereon. After the brass heads have been cast on,
they can be finished by steam power or otherwise. The spring bottom ƒ may
either be made hollow as shown in Figure 3, or it may consist of a solid
cylinder. The said spring bottom f and cavity 9 are made of various lengths
to suit the various spikes to be held in the dies.
By the use of my Invention the heads of nails and other similar articles
are made more regular in form, and better secured than when made by the
ordinary method.
Having now described the nature of my said Invention, and the manner of
carrying the same into effect, I wish it to be understood that I do not limit

page_text: myself.to.the precise details herein described and represented, as the same:
may be varied without departing from the nature, of my Invention; but I
claim as my Invention the new or improved machinery to be used.in: the
manufacture of rails, pins, screws, and other similar. articles herein-before
described, and illustrated in the accompanying Drawing; that is to say,. dies.
or tools for holding spikes or pins and other articles while heads, are formed
thereon, the said dies or tools having a yielding or spring bottom.

In witness whereof, I, the said Abel Stokes, have hereunto set my hand
and seal, this Third day of August, in the year of our Lord One
thousand eight hundred and-fifty-seven
