We, CHARLES BOTTOM, of Howard Road, Steel Bank, Sheffield,
Mechanic, and JOSEPH HALLAM, and SAMUEL WESLEY HALLAM, both of
Attercliffe Road, Sheffield, Merchants and Manufacturers, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY
OR APPARATUS FOR FORMING, HARDENING, TEMPERING, STRAIGHTENING, AND CUTTING
PARAGON OR OTHER WIRES TO BE USED FOR RIBS AND STRETCHERS OF UMBRELLAS OR
OTHER USEFUL PURPOSES," to be as follows:-
نا
This Invention relates to certain improvements in the arrangement
and combination of machinery or apparatus for the purpose of forming
or shaping, hardening, tempering, and cleaning, straightening, and
cutting off in any desired lengths paragon or other sections of wire used
for the ribs and stretchers of umbrellas and other useful purposes, the
object of the Invention being to perform all these operations by a
continuous process or series by self-acting machinery, whereas heretofore

page_text: such operations have been performed separately. The wire to be treated
is first wound in coils around a suitable cylinder or drum, which is set
in bearings in a frame or standards, near which the shaping rolls are
supported in the ordinary manner; they are provided with the requisite.
grooves and projecting surfaces in and around their peripheries for
receiving and shaping the wire, as, for example, in the event of a paragon
stretcher being required the lower roll would be cut with the proper
section and size of outer grooves for the flat band or wire to be
shaped, the upper roll being made with corresponding projecting
surfaces to-form-the-internal-grooves of the paragon stretcher. The wire
or wires thus formed or shaped are then conducted by travellers or
bearing rollers or other equivalent means to a furnace, where they are
heated to a suitable degree and thence passed through a cistern or tank
of oil or water in order to harden them, after which they are drawn
through heated plates in order to effect the straightening, tempering,
and cleaning, and finally they are cut off to the lengths required by
shears or cutters.
In order to regulate the motion and speed of the various portions of
the machinery toothed gearing is applied, whereby great accuracy and
power is given to the operation of the shaping rolls, and the process of
the wire throughout the series of operations is regulated; clutch motions
may also be applied to detach or arrest the action of one process whilo
another is being performed; the cutters can in like manner be caused to
act at definite intervals so as to detach uniform lengths of wire, such

lengths being changed when required by means of the gear.
being communicated from a steam engine to the driving wheel or band
pulley of the machine all the motions are effected in a continuous series.
By the same machinery the shaping rolls being changed, other sections
or patterns of wire may be similarly treated applicable to a variety of
useful purposes of wire or metal work.
