I, JOHN GEORGE PARKER, of No 11 Queen Victoria Street, in the City of
London, Civil Engineer, do hereby declare the nature of this invention, to be as
follows:-
The improvements consist in the manufacture of metal wires bars or rods of a
grooved corrugated, toothed, or stellar form in cross section, by drawing or other-
wise forming same with longitudinal wings, ribs, webs, bars, ridges grooves or
indentations, and by rolling and squeezing the central part (or solid core) thereby
extending and consolidating it and also spreading or upsetting the ribbed, webbed,
or barred portion and extending it both longitudinally and in section; the object
being to obtain from any given weight of ordinary plain round angular or square
sectioned metal wire or tube, bar or rod an extended area of surface in cross
section over the cross section of such ordinary wire or tube or rods, with or
without a denser solid core-Metal tubes may be treated with or without the
interposition of a permanent or removable solid mandrel or core.
The improvements are performed by taking, or making ordinary wrought metal
wire bar rod or tube as at present and forming by drawing, rolling, or otherwise,
straight or curved longitudinal channels or grooves on the surface of the same,
as many as desired and convenient-preferably parallel one to the other-said
channels or grooves being for the reception of sundry metal rolling and squeezing
discs, which are arranged one for each groove and to work in suitable frames and
supports with pressure adjustments at their axles-the action of these discs
compress the solid or hollow core and spread out the wings, ribs, webs, bars and so
form a wire bar, rod, bar, or tube of a star like cross section having wings ribs
or bars radiating from the centre of a solid or tubular core.
The revolving discs or rolls are arranged to run in a grooved or slotted frame
and have adjusting gear at their axles for regulating the pressure, they are also
made removable for repair-the vertical position of the discs, looking at them
edgeways and along the wire to be rolled, converges to or radiates from the centre
of a hollow die or support which holds the channelled wire & to be operated on,
this operation is performed by inserting and passing or drawing the wire between
the peripheries of the converging discs.

I, JOHN GEORGE PARKER, of No 11 Queen Victoria Street in the City of
London, Civil Engineer, do hereby declare the nature of this invention, and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
°
The improvements consist in the manufacture of metal wires bars rods or tubes
of a grooved corrugated, toothed, or stellar form in cross section, by drawing or
otherwise forming same with longitudinal wings, ribs, webs, bars, ridges, grooves
or indentations, and when desired rolling and squeezing the central part thereby
extending and consolidating it and also spreading the ribbed webbed or barred
portion and extending it both longitudinally and in section, the object being to
obtain from any given weight of ordinary plain round angular flat or square
sectioned metal wire or tube bar or rod an extended area of surface in cross section
over the cross section of such ordinary wire or tube or rods with or without a
dense or solid core. Metal tubes may be treated with or without the interposition
of a permanent or removable solid mandrel or core.
The improvements are performed by taking or making ordinary wrought metal
wire bar rod or tube as at present and preliminarily forming same by drawing them
through a die, rolling or otherwise forming straight or curved, longitudinal
channels or grooves on the surface of the same, as many as desired, and where
convenient, preferably parallel one to the other said channels or grooves being
for the reception of sundry metal rolling and squeezing discs which are arranged
one for each groove.-The action of these discs compresses the solid core and in
the case of tubes makes indentations in the same and spreads out the wings, ribs
webs bars and so forms a wire bar rod or tube of a star like cross section having
wings ribs or bars radiating from the centre of a solid core or tube.
The revolving discs or rolls are supported and arranged to turn on axles in
suitable journals in a grooved or slotted frame and have adjusting gear at their
axles for regulating the pressure they are also made removable for repair the
vertical position of the discs looking at them edgeways and along the wire to be
rolled converges to or radiates from the centre of a hollow die or support which
holds the channelled wire & to be operated on, this operation is performed by
inserting and passing or drawing the wire between the peripheries of the
converging discs.
The accompanying drawing shows a machine for making the said material but
I do not limit myself to this or any construction of apparatus.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The manufacture of metal wires bars rods or tubes of a grooved corrugated,
toothed, or stellar form in cross section, by drawing or otherwise-forming same
with longitudinal wings ribs webs bars ridges grooves or indentations and when
desired rolling and squeezing the central part thereby extending and consolidating
it and also spreading the ribbed webbed or barred portion and extending it both
longitudinally and in section.
2. The revolving discs or rolls arranged supported and made to turn on axles in
suitable journals in a grooved or slotted frame and having adjusting gear at their
axles for regulating the pressure, all substantially as described.
