or other suitable gearing and the wire or formed strip of metal passes between
them continuously. We make the rolls by preference of two or more pieces, in
which cast iron and steel or other metals may be combined. One form of roll
consists of 3 discs of metal bolted together on a spindle. Another form consists of
a steel ring held by cast iron or other flanges, the ring fitting on a projection on
one of the flanges.

The object of our Invention is to roll, shape, cut, and straighten wire and metal,
and it is applicable to making what is known as paragon" ribs and stretchers for
umbrellas. In order to cleanse and soften the wire previous to forming or shaping
it we propose to draw the wire through a bath of molten lead, which both
anneals and cleans the wire, leaving it in a fit state for entering the shaping rolls.
We make use of a pair of rolls or disks, by preference on vertical axes supported
in adjustable bearings in a suitable-frame; in one of these rolls we form an annular
groove of any desired form, and on the other roll is an annular flange or projection
corresponding to the groove, so that when the rolls are working there is sufficient
space between the flange and the groove for the metal to be rolled or formed to the
shape required. In front of these rolls we place a guide roll or rolls to press the
wire or metal against the grooved roll, and in some cases we also use an additional
pair of rolls with groove and flange for the preliminary bending or shaping of the
metal before it enters the main rolls. Immediately on leaving the rolls the wire
enters a guide plate, formed by preference in two parts, in one of which is a
groove; one end of the guide plate is tapered to enter the groove in the
roll. In line with and just beyond this guide is another guide or straightener,
formed also in two pieces, in one of which is a groove, and on the other
is or may be a projection corresponding to the channel in the wire or metal
being rolled. This guide or straightener is curved at one end, and one part
of it is adjustable to straighten the wire or metal being rolled. Between the
first named guide plate and the straightener we place a cutter, by which the
metal is cut off automatically to any desired length. When it is desired to cut
different (or unequal) lengths without stopping the machine we place more than
one cam on a shaft to actuate the cutter. The rolls are driven by spur wheels or
other suitable gearing, and the wire or formed strip of metal passes between them
continuously. We make the rolls by preference of two or more pieces, in which
cast iron and steel or other metal may be combined. One form of roll consists of
three disks of metal bolted together on a spindle. Another form consists of a
steel ring held by cast iron or other flanges, the ring fitting on one of the flanges.
And in order that our Invention may be fully understood and readily carried
into effect, we will describe the accompanying Sheet of Drawings, reference being
had to the figures and letters marked thereon.
Fig. 1 is a front elevation; Fig. 2 is a side elevation; and Fig. 3 is a plan of our
improved machine for rolling, cutting, and straightening wire and metal; Fig. 4 is
a. detached view of our improved construction of "roll" for rolling wire and metals.
a is the machine frame; b is a guide through which the wire or other metal to be
rolled is fed to the grooved roll c and the flanged roll d (for rolling paragon rib), or
rolls to produce other shapes may be used between which the wire is rolled; d' is
a bracket in which the spindle of the flanged roll d revolves, this bracket is
adjustable on horizontal and vertical slides; e is a guide plate formed in two parts,
and provided with a small bowl which runs in the groove in the metal being rolled.
The guide plate is mounted on a sliding bracket e¹; fitted on the upper part of the
frame a is a sliding table ƒ on which is mounted the fixed cutter g and movable
cutter g'; h is a wedge shaped steel plate on the bracket which is fixed to the
frame a; when the table is moved forward one end of the cutter g¹ slides on h and
is moved inwards by it to cut off the wire; j is a straightener formed in two parts

page_text: mounted on the table f, the straightener is provided with a small bowl similar to
that in the guide e; k is a vibrating lever connected to the sliding table f and
to the sliding lever k', in one end of which is a slot to allow it to move on the
cam shaft ; at the other end of the lever k¹ is an adjusting screw 2 to regulate
the traverse of the table f and the cut off; the table f and the cutters travel
in the same direction as the paragon rib while it is being cut. On the shaft
is a cam m working against a bowl n on the lever to actuate the table f
and the cut off; o is a second cam on the shaft which works against a bowl o¹
on the lever k¹ to give the return motion to the table. Different lengths of paragon
ribs or other sections may be cut by changing the gears 22, 23, 24, which actuate
the sliding table and cutters. A small bowl on one piece of the guide e straightens
the paragon rib as it leaves e. A similar bowl (or bowls) is used on the
straightener j. The machine is driven and geared as follows:-The driving
pulley is keyed to the shaft p¹ on which is keyed the pinion p² which gears into
and drives the spur wheel r on the shaft 21 on which is keyed the bevil wheel s
for giving motion to the shaft t, on the other end of which is a bevil wheel t¹
which drives the roll c; the roll d is driven by spur gearing from the roll c.
On the shaft is keyed the wheel 2 which drives by the carrier wheel 3 (on
a stud fixed to the quadrant arm u) and the spur wheel r, the cam shaft 7; the
arm swings on the shaft . We make the roll c (see Fig. 4) of a disk of steel
forged between two disks of iron in order to prevent "skelling or buckling in
hardening. Fig. 4 is a view of a "roll" made according to our Invention. In
this case the roll is similar to the female roll c for forming paragon ribs, and it is
made with a centre portion or plate x of steel previously united in the forge or by
other means to and between two plates of iron y and y'; this combined roll is
fixed on a spindle between two metal flanges z and z¹. The advantages accruing
from this mode of making rolls are that there is less liability to crack, fly, break,
twist or lose their form in the process of hardening. Rolls made on this principle
may be applied for all purposes in which steel rolls are required, and a number of
iron and steel disks may be combined in one roll when it is desired to roll more
than one section. Flanges of cast iron or other metal may be used to stiffen the
centre portion. The flanged roll d is composed of a disk of steel held between two
metal collars or flanges.
"
We have not shown a lead bath on the Drawing, but when we use one it is placed
between the swift or reel and the forming rolls.
Having now described and ascertained the nature of our said Invention, and in
what manner the same is or may be performed, we declare that we claim as
secured to us by the hereinbefore in part recited Letters Patent,-
1. Forming, straightening, and cutting to lengths "paragon ribs" and other
sections of metal continuously, substantially as shown and described.
2. The cutters g and g¹ mounted and actuated as and for the purpose shown and
described.
3. The "rolls" made of steel and iron combined, substantially as shown and
described.
4. The use of a bath of molten lead to anneal and clean the metal before going
through the forming rolls c and d as described.
5. The general combination and arrangement of parts forming a machine for
rolling, cutting, and straightening wire and metal, as shown and described.
In witness whereof, I, the said Henry Bernoulli Barlow, for myself and on
behalf of the said Robert Ashmore Hill, have hereunto set my hand and
seal, this Nineteenth day of May, One thousand eight hundred and eighty one.
