IMPROVEMENTS IN MACHINERY FOR MAKING ORNAMENTAL METALLIC STRIPS, RODS, AND TUBES
Year: 1876

page_text: LETTERS PATENT to William Nokes, of Aston, near Birmingham, in the
County of Warwick, Manufacturer, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR MAKING ORNAMENTAL METALLIC STRIPS, RODS, AND TUBES."
Sealed the 6th April 1877, and dated the 24th October 1876.
PROVISIONAL SPECIFICATION left by the said William Nokes at the Office
of the Commissioners of Patents on the 24th October 1876.
WILLIAM NOKES, of Aston, near Birmingham, in the County of Warwick, Manu-
facturer. "IMPROVEMENTS IN MACHINERY FOR MAKING ORNAMENTAL METALLIC
STRIPS, RODS, AND TUBES."
In ornamental strips, rods, or tubes there is a plain space or bar between the dies
or rolls which make the ornament, the plain edges of these rolls always leaving a
plain bar.
My Invention consists in cutting or indenting the edges of these rolls, and in
machinery for so fixing and working them that the now plain bar will by its
indented edges make an ornamental bar of any desired pattern. This is illustrated
in the accompanying Drawings, in which,―
(A) Fig. 1 shews the present plain bar, and (A) Fig. 2, the ornamental one
produced by the peculiar edge formation of the embossing rollers used for orna-
menting the spaces of the tube between the bars.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Nokes in the Great Seal Patent Office on the 19th April
1877.

STRIPS, RODS, AND TUBES,"

page_text: This Invention consists in improvements in the manufacture of fancy strips, rods,
and tubes. I use the ordinary kind of rolls or revolving dies working on a spindle
or axle, and also the ordinary kind of frame to hold these dies.
With the addition of certain appliances to suit my Invention, the pattern
produced in the manufacture of ornamental strips, rods, or tubes is always cut or a
engraved on the revolving rolls or dies. The pattern sometimes breaks through the
edge of the roll, and thus unites itself with the bar (a) seen in Figure 1. This
breaking into the edges of the bar is to complete the pattern, not to increase the
amount of ornamentation, for the plain straight line of the pattern, as well as the
plain straight line of the bar, are apparent through the whole length of the strip,
rod, or tube. These roller dies are 3, 4, 6, or 8 in number. As the strip, or rod, or
tube is drawn through, the dies revolve and the impression sunk on them is
produced on the tube, rod, or strip. But the object hitherto sought for has been to
obtain on the metal the pattern cut on the face of the roller die, and not to produce
any ornamentation by its edges.
My Invention consists in making indentations in the edges of the roller dies by
cutting away a part of the groundwork sunk on them. Rolls so cut or indented not
only make a pattern by their impression on the surface of the metal, but they
greatly increase the ornamentation by raising on each side of this pattern a fancy or
ornamental edge, as seen in Figure 2, instead of a plain straight edge, as in Figure 3.
I make these indentations by cutting away the face of the roll, or by cutting away
its sides to the face, both ways producing the same results, an indented edge.
With an indented edge corresponding with the pattern sunk in the rolls instead of
a plain straight edge, the pattern stands out with more effect, and new results are
obtained. There is an ornamental edge corresponding in form with the pattern
sunk in the roller dies, as seen in Figure 4.
In working these revolving dies or rolls, to produce an exact pattern on the bar
they must all be of one diameter; the pattern must be cut in each with great
exactness, and they must all begin to revolve together. To produce this last result
I cut away on its side a portion of the roll as seen at (b) Figures 5 and 6. This
cutting straight into the body of the roll, and of sufficient depth at one end, tapers
out or softens off on to the flat of the roll at the other end. In the frame, Figures 7
and 8, in which this roll works I put a peg (c) with a spring (d) on the top of it. As
this spring peg (c) works on that part (b) of the roll when the cutting is made, the
roll can work one way without any obstruction, but cannot work the other. As it
revolves the right way the spring peg (c) falls into the deep end (e), Figure 6, of the
slot, and it is lifted by the action of the roll up the gradual slope of the cutting on
to the flat side of the roll until a revolution has been made, when the peg (c) falls
into the deep part (e) of the slot and works out again as before. The freedom of
the action of the roll is not therefore interfered with while it works one way. But
it can only make one revolution in the opposite way, for the spring peg (c) then
works down the slot and stops the roll when it reaches its deep straight cut end.
Before the tube is put into the roller dies, the workman with his finger, or with a
tool made for that purpose, turns each of the roller dies back until they stop against
the shoulder at the deep end of the slot. Every one of the dies will then be in its
exact position to produce the required design or ornament on the bar of the tube as
seen in Figure 4.
There are other methods of fixing and starting these roller dies at any desired
place so that an ornamental bar may be produced, but these are only other ways of
obtaining the same results, namely, an ornamental bar, thereby producing an increase
of ornamentation on fancy tubes, rods, and strips.
Having thus described the nature of my said Invention and the manner in which
the same is to be performed, I claim, without limiting myself to these precise details,
the improvements in machinery for making ornamental metallic strips, rods, and
tubes by which both sides of the pattern cut in the die are enclosed with an indented
or ornamental edge instead of a plain straight edge, and I also claim fixing and

page_text: working the roller dies cut as above in such manner that the hitherto plain straight
bar shall become a fancy or ornamental bar with a definite pattern on it, as herein
more fully set forth and specified.
In witness whereof, I, the said William Nokes, have hereunto set my hand and
seal, this Seventeenth day of April, in the year of our Lord One thousand
eight hundred and seventy-seven.
WILLIAM NOKES. (L.S.)
