IMPROVEMENTS IN TEIR METHOD OF IND PROVISIONAL SPECIFICATION
Year: 1882

page_text: LETTERS PATENT to Sam Wood, Matthew Wood and Arthur Wood of the
firm of John Wood and Sons of Brighouse in the County of York, Wire
Manufacturers for an Invention of "IMPROVEMENTS IN TEIR METHOD OF IND
PROVISIONAL SPECIFICATION left by the said Sam Wood, Matthew
Wood, and Arthur Wood at the Office of the Commissioners of Patents on
the 10th August 1882.
SAM WOOD, MATTHEW WOOD and ARTHUR WOOD, of the firm of John Wood
and Sons of Brighouse in the County of York, Wire Manufacturers IMPROVE
"
MENTS IN THE METHOD OF AND APPARATUS FOR HARDENING AND TEMPERING
STEEL WIRE
"
The object of our Invention is to harden and temper steel wire for card making
purposes; and this we accomplish by passing wire through the flame of a furnace
by which the wire is softened previous to hardening and tempering At the outlet
of the furnace we place a cistern containing oil through which the wire passes to be
cooled and consequently hardened, the wire thence passes through a lead bath
which tempers and finishes it ready to be wound upon "winders " or creels.
The furnace is composed of a solid bed of brick-work having a fire underneath,
and for the purpose of distributing the flame one or more jets of steam and air is
blown under the grate bars; we also employ one or more jets of gas (by preference)
coal gas at the entrance end of the furnace which also distributes the flame and
helps to heat the furnace.
Between the oil cistern and lead bath the wire passes through a piece of India
rubber or other suitable substance, which wipes off the oil previous to the wire
entering the lead bath.
The oil cistern is placed in a larger cistern which catches the oil as it escapes out
of the openings through which the wire enters, the oil being pumped back again
into the smaller cistern so that it always remains full.

In order that our Invention may be better understood we herein give reference
to the accompanying Sheet of Drawings where Fig. 1 is elevation of a furnace
and parts connected therewith constructed and arranged according to our Invention
and Fig 2 is end view shewing entrance for wire.
A is the furnace which is composed of a solid bed of brickwork having a fire B
underneath and for the purpose of distributing and spreading the flame, one or
more jets of steam and air is introduced underneath the grate bars of the furnace.
The said steam passes through the pipe C the said pipe extending down and through
the larger pipe D which supplys air, both of such pipes entering the brickwork at
E and into a rectangular box W shewn in details Figs 4, 5 and 6 the air and
steam escaping therefrom through openings X to the grate bars.

softened, which takes place whilst it passes through the heated chamber G, which
in addition to heat generated by the furnace receives additional heat by coal gas
supplied at the entrance of the chamber by pipes H as shewn in elevation and
sectional plan Fig. 3.
After the wire has been heated and softened, it must be hardened, and this takes
place by passing it through the cistern I which contains oil. The wire passes
through slits made in the upper edge at each side of the cistern, which is placed
in a larger cistern J for catching the overflow as it escapes through the slits, the
said overflow being pumped back again into the smaller cistern by a pump K so
that the said cistern is always full. The pump K is operated by pulley and
strap L.
After the wire has been hardened, it must be tempered, and this is effected by
passing the wire through a cistern M containing molton lead heated by a furnace N,
and in order that the wire may be properly immersed it passes under a bar or
pulley O in the bath passing out at P and after traversing around pulleys R is
wound on to "winders" S in a finished state.
Between the oil cistern and lead bath the wire passes through a piece of india-
rubber or other suitable material T which wipes off the oil previous to the wire
entering the lead bath.
Having now shewn and described our Invention, and the manner in which the
same may be performed, we would have it understood, that we do not confine
ourselves to the exact details herein shewn, and described, as they may be varied
without departing from the main features thereof but what we consider to be
new and therefore claim as our Invention is,
Firstly. The chamber G heated by means of a furnace and gas, in manner and
for the purpose substantially as described.

page_text: Secondly. The introduction of air and steam into the furnace in manner and for
the purpose substantially as herein shewn and described.
Thirdly. The use and employment of the pump K for the purpose substantially
as shewn and described.
In witness whereof we the said Sam Wood, Matthew Wood, and Arthur
Wood have hereunto set our hands, and seals this First day of February,
in the year, One thousand, eight hundred and eighty three.
