Year: 1847

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
JOHNSON, of Bradley, in the Parish of Bilston, in the County of Stafford, Iron
Founder and Boiler Maker, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twelfth day of June,
One thousand eight hundred and forty-seven, in the tenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
James Johnson, my exors, adiňors, and assigns, Her especial licence, full
power, sole privilege and authority, that I, the said James Johnson, my
exors, adiñors, and assigns, and such others as I, the said James Johnson,
my exors, admors, or assigns, should at any time agree with, and no others,
from time to time and at all times during the term of years therein expressed,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "IMPROVE-
MENTS IN MACHINERY FOR THE MANUFACTURE OF RIVETS, RAILWAY OR OTHER
PINS, BOLTS, NUTS, AND SPIKES;" in which said Letters Patent is contained a
proviso, that I, the said James Johnson, should cause a particular description
of the nature of my said Invention, and in what manner the same is to be
performed, by an instrument in writing under my hand and seal, to be

page_text: more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
James Johnson, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are fully described
and ascertained in and by the following statement thereof, reference being
had to the Drawings hereunto annexed, and to the figures and letters marked
thereon, that is to say :-
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a side elevation of a machine constructed according to the
first part of my Invention; Figure 2 is a plan thereof; and Figure 3 shows
a front view. a is a lever moving on an axis at 6; this lever carries the
heading die c, as shewn. The lever a is worked by means of power applied
to the axis d, on which is fixed the pinion e, which gives motion to the cog
wheelf on the axis g, on which is fixed the wheel h, in which studs or pins i,
with friction rollers, are placed in such succession as to move the lever as
often as may be desired at each revolution of the axis. 9 and j is a screw to
adjust the distance through which the punch or heading die shall be moved,
all which is similar to what has already been done in machinery for like pur-
poses. is what I call the horizontal bar or bed for carrying the dies, in
which the pieces of metal for making the rivets, pins, bolts, nuts, or spikes are
placed, and which dies are similar to those heretofore used. And thus far the
combination of machinery is not of my invention, excepting so far as the bar
or bed k is capable of carrying several dies, and of being moved step by step
under the punch or heading die at each movement of the lever a.
The bed or
bar constituting the horizontal moving bed or bar moves in a dovetail fixed
block as shewn, and it has a toothed rack formed or fixed on its under side, by
which means the cog wheel k¹ on the axis l, gives motion to the bed or bar
carrying the dies.
m, m, are a series of dies placed in recesses in the bed or
bar, which I believe is the best arrangement; but the dies may be fixed or
form part of the bed or bar if preferred, the object being that a bar or bed
carrying a series of dies may be moved under the punch in proper order, so as
to have the metal which is placed in the series of dies acted on by the punch
or upper die in succession. On the axis is a ratchet wheel ', which is driven
by the clawker n, worked by the lever a, and there should be a click or clicks

page_text: to prevent the ratchet wheel moving back when not desired to do so, as is well
understood. The dies are to be placed in the bar or bed, and pieces of metal
are to be placed in the dies, when the working of the machinery will cause
each of the pieces of metal in the dies to be acted on by the punch, and when
the same have been operated on the dies will be removed and replaced by
others, and the bed or bar run back by the other bar being brought into action
on the other ratchet wheel and clawker n².
I will now describe another part of my Invention which has for its object
a more correct cutting of the lengths of the rods used in making rivets, pins,
bolts, and spikes, by means of saws. Figure 4 shows a plan, and Figure 5 a
front view, and Fig. 6 a side view of a machine for this purpose. o is a
sliding plate having a tube p fixed thereto. 9 is an axis carrying two circular
saws, such as are usually employed for cutting iron; r is a handle by which
the slide o is moved; the rod of iron is forced through the tube from the end
(1) to the end (2), where it is stopped by any suitable stop; the slide is then
moved towards the saws and two lengths are cut off; the slide is then brought
back, and the rod, in being pressed through the tube for the next operation,
pushes out the previously cut lengths, and the slide is again moved into the
saws and fresh cuts are made. By this arrangement very accurately cut
lengths will be obtained, which is very important where the process of forging
the heads is done by machinery. It will be evident that the saws and the cuts
in the tube must be set at such distances apart as are required for the lengths
to be cut off.
Having thus described the nature of my Invention, and the manner of per-
forming the same, I would wish it to be understood that I do not claim the
use of several dies carried by other means than a bar or bed as herein des-
cribed, nor do I confine myself to the details herein shewn and described so
long as the peculiar character of either part of my Invention be retained; but
what I claim is, first, the mode of arranging a carrying bar or bed with dies,
and causing the same to move step by step to the upper die or punch; and,
secondly, I claim the mode of arranging apparatus for cutting lengths of rods
for making rivets, pins, bolts, and spikes.
In witness whereof, I, the said James Johnson, have hereunto set my
hand and seal, this Eleventh day of December, in the year of our Lord
One thousand eight hundred and forty-seven.
