We JOHN THORNTON Machine Maker and HENRY ELLISON Chemical Manufacturer
both of Cleckheaton in the county of York, do hereby declare the nature of my
Invention for "IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR HARDENING
AND TEMPERING STEEL BANDS IN LENGTHS OR CONTINUOUS BANDS," to be as
follows:-
This invention relates to further improvements on application N° 8618 dated
June 5th 1884.
i
In hardening and tempering steel bands either plain or serrated, for springs or
other purposes, the bands are passed through a furnace, heated by gas, or other
means, and they are then tempered by a blast of air, in an air chamber or box, by
which the temper can be regulated to any nicety.

COMPLETE SPECIFICATION.
We JOHN THORNTON of Northgate Cleckheaton Card Setting Machine Maker,
and HENRY ELLISON of Cleckheaton Chemical Manufacturer in the County of York,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
METHOD OF AND APPARATUS FOR HARDENING AND TEMPERING STEEL BANDS IN
LENGTHS, OR CONTINUOUS BANDS," and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
Our invention relates to further improvements on Patent N° 8618.
The object of our invention is by a simple, easy, and inexpensive method
to evenly and efficiently harden and temper (long or continuous lengths of flat,

DESCRIPTION OF DRAWINGS.
Fig. 1 shews an elevation partly in section of apparatus for carrying out our
improved process of hardening and tempering flat steel wire or banda,
Fig. 2 is a section of heating chamber.
Fig. 3, is a section of hardening and tempering chamber or box.
A is the gantry or frame of apparatus supported by legs B, C is a burner on the
bunsen principle, that is, burning part gas and part air, for heating the wire D, as
it passes from wincel E to wincel F, a coke or coal furnace, or other means may be
used for heating the bands; the bands pass through a tube or chamber H, (of
metal, fireclay, plumbago, asbestos, or other suitable material to protect the bands).
to the hardening and tempering box J, which may be made to hinge and open
when required, when passing through this box or vessel, it is subjected to a blast
or current of air, brought from a receiver by pipe K, and produced by a fan, blower,
or other suitable means, the hardeness or temper of the bands partly regulated by
the ordinary valve of the fan, blast, or blower; to further reduce, tone down, or
soften the temper of the bands, it passes over the small pan M, of boiling or heated
lead to the wincel F, the lead pan being heated by gas or other means, one, two,
three, or other numbers of bands may be passing through the apparatus and be
hardened and tempered at the same time.
Having now particularly described and ascertained; the nature of our said
invention, and in what manner the same is to be performed, we do not limit
ourselves to any particular construction of arrangement of oven, hardening box, or
pan, nor to any particular means of heating the same, but we declare that what
we claim is
The use and employment of a blast of air in hardening and tempering long or
continuous lengths of flat, corrugated, or steel bands, or wire.
