Year: 1861

page_text: LETTERS PATENT to Thomas Taylorson Jopling, of Sunderland, for the
Invention of "IMPROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF
BOLTS, SPIKES, SCREW BLANKS, AND RIVETS."
Sealed the 13th December 1861, and dated the 18th June 1861.
PROVISIONAL SPECIFICATION left by the said Thomas Taylorson Jopling
at the Office of the Commissioners of Patents, with his Petition, on the
18th June 1861.
I, THOMAS TAYLORSON JOPLING, of Sunderland, do hereby declare the
nature of the Invention for "IMPROVEMENTS IN MACHINERY FOR THE MANU-
FACTURE OF BOLTS, SPIKES, SCREW BLANKS, AND RIVETS," to be as follows:-
This Invention has for its object improvements in machinery for the manu-
facture of bolts, spikes, screw blanks, and rivets. For these purposes, the
dies are received into the face of a disc, which is mounted on a fixed axis.
The disc receives a step-by-step movement at intervals, as hereafter explained,
a distance equal to that between the centres of two dies. On the periphery
of the disc is formed ratchet teeth, one for each die, carried by the disc. On
the axis on which the disc is carried is an arm which moves freely on such
axis, and in front of the disc. This arm carries a driver which, when the arm

page_text: is moved, takes into the ratchet teeth, and gives motion to the disc, and such
arm also carries a cutting edge, which, together with a stationary cutter,
causes the bar or rod, when its end has been introduced into a die in the disc,
to be cut. The fixed cutter consists of a bar fixed to one side of the machine,
so as to admit of its being adjusted in position. At the end of this bar is a
hole of a suitable size for the passage of the end of the rod or bar through it
into one of the dies carried by the disc, so that when the disc and the arm
carrying the other cutter are moved one step the end of the bar will be cut
off at the point where it comes through the hole or passage in the fixed cutter.
The arm which moves the disc and carries a cutting edge receives motion by
means of a connecting rod attached to a crank pin on a disc on the end of a
shaft which receives motion from the main shaft by bevil-toothed wheels; it
will consequently be seen that by simply moving the arm which carries one of
the cutters, the disc carrying the dies will be moved one step, or a distance
equal to that between the centres of two dies, and by such movement a
portion of metal will be cut off from a bar or rod, and remain in one of the
dies.
The main or driving shaft receives motion from a steam engine or other
power, and by means of a cam formed or fixed thereon it gives motion to the
heading die, which is carried by a cross head which is in front of the face of
the disc, and such cross head is mounted on the ends of two sliding bars or
rods. The cam acts on a roller carried by a strong block of wood, which is
fixed to the two sliding bars or rods above mentioned, by which the cross head
and heading die are moved towards one of the dies in the face of the disc and
thus forms a head on the length of the bar or rod contained in the die; this
cam also moves the cross head away from the disc. Another cam on the
main shaft gives motion to a rod which forces the article out of the die, if it
be a short one, and partly out if it be a long one, and the cam gives motion
to another rod with a hook which takes hold of the head and removes the
article. It is preferred that the disc should be arranged to carry six dies, and
that the heading should be performed after a length of metal has been cut
off, and has been moved a second step with the disc to bring it into a position
to be formed with a head, and the cam for forcing out the article from the
dies acts after the disc has made one step or movement after the heading
punch has acted. When working with hot metal streams of water are caused
to flow through the dies after the article has been forced out, and water is also
supplied to the heading die.

by the said Thomas Taylorson Jopling in the Great Seal Patent Office
on the 18th December 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
TAYLORSON JOPLING, of Sunderland, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of June, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Thomas Taylorson Jopling, Her special licence that I, the said Thomas
Taylorson Jopling, my executors, administrators, and assigns, or such others
as I, the said Thomas Taylorson Jopling, 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 MACHINERY FOR THE MANUFACTURE OF BOLTS, SPIKES, SCREW
BLANKS, AND RIVETS," upon the condition (amongst others) that I, the said
Thomas Taylorson Jopling, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should par-
ticularly 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 immie-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Thomas Taylorson Jopling, 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:―
This Invention has for its object improvements in machinery for the manu-
facture of bolts, spikes, screw blanks, and rivets. For these purposes, the
dies are received into the face of a disc, which is mounted on a fixed axis.
The disc receives a step-by-step movement at intervals, as hereafter explained,
a distance equal to that between the centres of two dies. On the periphery of
the disc is formed ratchet teeth, one for each die, carried by the disc. On the
axis on which the disc is carried is an arm which moves freely on such axis,
and in front of the disc; this arm carries a driver which, when the arm is
moved, takes into the ratchet teeth, and gives motion to the disc, and such
arm also carries a cutting edge, which together with a stationary cutter, causes

page_text: the bar or rod when its end has been introduced into a die in the disc to be
cut. The fixed cutter consists of a bar fixed to one side of the machine, so as
to admit of its being adjusted in position. At the end of this bar is a hole of a
suitable size for the passage of the end of the rod or bar through it into one
of the dies carried by the disc, so that when the disc and the arm carrying
the other cutter are moved one step, the end of the bar will be cut off at the
point where it comes through the hole or passage in the fixed cutter. The
arm which moves the disc and carries a cutting edge receives motion by means
of a connecting rod attached to a crank pin on a disc on the end of a shaft,
which receives motion from the main shaft by bevilled toothed wheels; it
will consequently be seen that by simply moving the arm which carries one of
the cutters, the disc carrying the dies will be moved one step or a distance
equal to that between the centres of two dies, and by such movement a
portion of metal will be cut off from a bar or rod, and remain in one of the
dies.
The main or driving shaft receives motion from a steam engine or other
power, and by means of a cam formed or fixed thereon it gives motion to
the heading die, which is carried by a cross head which is in front of the
face of the disc, and such cross head is mounted on the ends of two sliding
bars or rods. The cam acts on a roller carried by a strong block of wood,
which is fixed to the two sliding bars or rods above mentioned, by which the
eross head and heading die are moved towards one of the dies in the face of the
disc and thus forms a head on the length of the bar or rod contained in the
die; this cam also moves the cross head away from the disc. Another cam
on the main shaft gives motion to a rod which forces the article out of the
lie, if it be a short one, and partly out if it be a long one, and the cam gives
motion to another rod with a hook which takes hold of the head, and removes
the article. It is preferred that the disc should be arranged to carry six dies,
and that the heading should be performed after a length of metal has been
cut off, and has been moved a second step with the disc to bring it into a
position to be formed with a head, and the cam for forcing out the article from
the dies acts after the disc has made one step or movement after the heading
punch has acted. When working with hot metal streams of water are caused
to flow through the dies after the article has been forced out, and water is also
supplied to the heading die.
And in order that my Invention may be most fully understood and readily
carried into effect, I will proceed to describe the Drawings hereunto

page_text: DESCRIPTION OF THE DRAWINGS.,
Figure 1 is a side view, Figure 2, a plan, and Figure 3, a front view, of a.
machine constructed according to my Invention; Figure 4 is a section of the
same taken through the line A, B, Figure 3.
A is the framing of the machine; this frame carries the driving shaft B, on-
which are the fast and loose pullies C. On the shaft. B is also a fly-wheel D
and pinion E, which takes into the toothed wheel F on the shaft G; this
shaft carries a bevil wheel G³, which gears into another similar wheel on the
shaft. H. On the end of this shaft is a disc I, on which is a stud J, which by
a connecting rod J', gives: a to-and-fro motion; to the lever K, which turns.
upon the same axis as the disc N that carries the dies. On the lever K is a
cutter L for cutting the rod of metal L³ into suitable lengths; the lever K
also carries a pawl M for giving a step-by-step motion to the disc N, so that
the disc N moves one step for each forward movement of the lever. The
disc N is shown in the Drawings to have six dies O, fitted into it, but it may
be fitted with any other suitable number, the disc always having as many
teeth formed on it for the pawl M to-take into as there are dies fitted to the-
disc. The rod of metal to be made into bolts or other articles is fed in suc-
cession, as the disc revolves into the dies O through the tube P, a fresh die
coming opposite the tube at each step of the disc, and the rod of metal being
pushed forward each time into the dies. After the rod has been pushed
forward into a die, the cutter L, carried by the lever K, is by the movement
of the lever moved across the end of the tube P, which is nearest the disc N,
and a length of the rod is thus cut off. The tube P is held in position by the
arm or bracket Q, Figures 3 and 4, the tube P sliding through a hole in its
end. The tube P is also connected by the arm S to the rod R, on which is
fixed the hand wheel R', and by turning this hand wheel, as will be seen at
Figure 5, the tube P and lever K can be moved to or from the disc N, and
the length of the cut-off piece of rod which is left projecting from the mouth
of the die thereby regulated, thus regulating the size of the head. The
length of the bolt or other article is regulated by the length of the loose
pins O' at the bottom of the dies. The heading die T is carried by the cross
head U, which is bolted to the ends of the rods V', V, which slide through
holes in the two ends of the frame A. Motion is communicated to the heading
5 die from a cam G¹ on the shaft G; on each side of this cam is a friction roller
W, W. Each friction roller is carried by a cross head X; these cross heads
rest against blocks of wood X', X', which are interposed between the cross
heads and the nuts X2, X². These blocks of wood are for the purpose of

page_text: giving spring to the heading die. The cross head Z on the opposite ends of
the rods V, V, to those to which the cross head U is bolted carries a swage Z',
which works in conjunction with another swage Z³ for pointing nails, spikes,
&c., to any required form. G' is a cam on the shaft G; this cam gives
motion to an arm Y³; this arm gives motion to a rod Y', the end of this rod
pushes the bolt or other article after it has been headed out of the die. 'The
arm Y³ also gives motion to another rod Ys, which slides through the frame
below the disc; this bar is used to remove articles from the dies that are
longer than the bar Y¹ will discharge, it being formed with a hook at its end,
as shown at Figure 3. This hook catches the article already partly pushed
out by the rod Y behind its head, and completes its discharge at the next
step movement of the disc.
In witness whereof, Thomas Taylorson Jopling, have hereunto set my
hand and seal, this Sixteenth day of December, in the year of our
Lord One thousand eight hundred and sixty-one.
