PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Hardening and
Tempering in Continuous or other Lengths Steel Wire Bright.
We, EDWIN ODDY, Mechanic, JOSEPH CROSSLEY, Wiredrawer's Manager,
ENOS SMITH and AI SMITH, Wire Manufacturers, all of Phoenix Works,
Cleckheaton in the County of York, do hereby declare the nature of this
invention to be as follows:-
The object of our invention is to obtain a bright wire by a simple and effective
method of hardening and tempering the same.
We run the wire or wires through an ordinary solid flame or flames to heat it,
then it is passed through a nozzle or other conductor (connected to the oil reservoir)
and charged with oil, which oil ignites at the end of the nozzle joining up to the
gas flame, so that there is no air or other space between the flame and the oil, and
so no oxidisation takes place, it is then heated by solid flame or flames for
tempering, and passes through a trough of sand or other suitable material, there
being again no space between the tempering flames and the sand, oil may again
be applied at the end of the sand trough so that the flame joins up to the tempering
flame.
The nozzle or nozzles have preferably a taper hole, larger near the reservoir and
a circulating hole preferably on its underside, to increase the circulation and
prevent clogging.

Improvements in the Method of and Apparatus for Hardening and
Tempering in Continuous or other Lengths Steel Wire Bright.
We, EDWIN ODDY, Mechanic, JOSEPH CROSSLEY, Wiredrawer's Manager,
ENOS SMITH and AI SMITH, Wire Manufacturers, all of Phoenix Works,
Cleckheaton in the County of York, 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 object of our invention is to obtain a bright wire by a simple and effective
method of hardening and tempering the same.
DESCRIPTION OF DRAWINGS.
Fig. 1. is an elevation of our improved apparatus for hardening and tempering
steel wire bright.
Fig. 2. is an enlarged detail in section of nozzle.
Fig. 3. shows view of cooling trough in which the wire passes by a tube through
the body of the oil or cooling liquid.
Fig. 4. is a modification of Fig. 1. showing apparatus at an incline Figs. 1. 2
and 3.
We run the wire or wires A through an ordinary solid flame or flames B to heat
it, then to harden it is passed through a nozzle or other conductor C (connected to
the oil or other liquid reservoir H) and charged with oil, which oil ignites at the
[Price 8d.1

page_text: end D of the nozzle C, joining up to the gas flame B, so that there is no air or
other space between the flame and the oil, and so no oxidization takes place, it is
then heated by solid flame or flames E for tempering, and passes through a trough
of sand, oil, lead or other suitable cooling material, there being again no air space
between the tempering flames and the sand, oil, lead or other cooling material, oil
may again be applied by nozzle C at the end of the said trough, so that the flame
from the nozzle joins up to the tempering flame.
The nozzle or nozzles have preferably a taper hole J larger near the reservoir,
and a circulating hole preferably on its underside K, to increase the circulation and
prevent clogging.
Fig. 4. The nozzle C in this modification is a plain nozzle, and the oil does not
run out and ignite at its end as in Fig. 1, but the gas flame is extended so as to
heat around the nozzle, and the oil or other tempering material seals the other end
of the nozzle, and excludes the air, preventing oxidization, the same with the
tempering flame and the nozzle of the cooling trough, the wire in the latter may
either pass through a nozzle with extended tube, or direct through the nozzle and
cooling liquid.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In apparatus for bardening and tempering wire bright, the prevention of
oxidization by passing the wires A, through the heating flames B, direct into the
adjoining flames from the hardening liquid H, and from the tempering flame E
direct into the adjoining flames of the cooling vessel F, substantially as shown and
described.
2. In apparatus for hardening and tempering wire bright, the prevention of
oxidization by passing the wires A through the heating flames B direct into the
hardening liquid H, and from the tempering flame E direct into the cooling vessel F
by joining the heating flames up to the nozzles C so excluding air, substantially as
shown and described.
