Year: 1875

page_text: LETTERS PATENT to Matthew Smith and Michael Holroyd Smith, both
of Halifax, in the County of York, Wic Manufacturers, for the
Invention of "IMPROVEMENTS IN APPARATUS TO BE EMPLOYED FOR ANNEALING
WIRE AND CONTINUOUS STRIPS OF METAL, AND FOR HEATING FOR THE PURPOSE
OF HARDENING AND TEMPERING THE SAME.
PROVISIONAL SPECIFICATION left by the said Matthew Smith and
Michael Holroyd Smith at the Office of the Commissioners of
Patents, with their Petition, on the 15th July 1875.
WC, MATTHEW SMITи and MICHAEL HOLROYD SMIт¤, both of Halifax,
in the County of York, Wire Manufacturers, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN APPARATUS TO BE EMPLOYED
FOR ANNEALING WIRE AND CONTINUOUS STRIPS OF METAL, AND FOR HEATING FOR
THE PURPOSE OF HARDENING AND TEMPERING THE SAME," to be as follows..
Heretofore wire has been annealed in cast-iron cylinders known as

--

page_text: "annealing pans," or by being passed through metal tubes supported in
a furnace by an arch of brickwork, or in what are termed anncaling
ovens.
According to this our Invention we construct a furnace containing a
series of longitudinally perforated fire-bricks or blocks having "butt
and socket" joints, the latter being further and securely closed by means
of cement or fire-clay
The wire to be anncaled or heated for hardening and tempering is
drawn through and along the perforations by means of a drum and crecl
or other like contrivance, and the necessary baths being provided, the
wire or strips may be cleaned or hardened, or tempered as required
during its progress from the furnace to the winding drum or drums.
Ax
SPECIFICATION filed in pursuance of the conditions of the Letters J
Patent, and by an Order of the Lord Chancellor, by the said Matthew
Smith and Michael Holroyd Smith in the Great Seal Patent Office
on the 14th February 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, MATTHEW
SMITII and MICHAEL HOLROYD SMITH, both of Halifax, in the County ?
of York, Wire Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of July, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Matthew Smith and Michacl
Holroyd Smith, Пer special licence, that we, the said Matthew Smith
and Michael Holroyd Smith, our executors, administrators, and assigns,
or such others as we, the said Matthew Smith and Michael Holroyd
Smith, our exccutors, administrators, and assigns, should at any time a
agree with and no others, from time to timo and at all times there-

page_text: application, we have annexed a Sheet of Drawings, and have marked
the several views with figures and letters of reference, the same letter
referring to the same part in each Figure.
Fig. 1 is a side elevation partly in section of a furnace or apparatus
for purposes aforesaid, having our improvements applied, Fig. 2 is an
end view.
Figs. 3 and 4 are details, enlarged scale (about one-fourth full size) of
our improved apparatus.
A is the furnace, within which are a series of fire-bricks or blocks B
built so as to form an arch having under and over flues C, D, for the
passage of the heated gases as indicated by arrows. The bricks or blocks
are perforated longitudinally for the passage of the wire or strip of
metal E to be operated upon, and which is drawn through or along the
perforations by means of a drum or crecl, and cach brick or block is
provided with butt and socket joints, the butt F being received within
the socket F, which not only serves to secure the whole together and
exclude the fire, but insures the longitudinal perforations at all times
being "true" or linable with each other, as it will be understood that
without the means herein described, in the event of any one brick or
block being displaced, the passing of a wire or strip of metal through
or along the perforations could not be effected.
By the use of the aforesaid means of connecting and securing the
bricks or blocks, we are enabled to construct fire-clay passages for
purposes aforesaid of any required length, which heretofore has not been
practical.
Having thus fully described the nature and particulars of this our
said Invention, together with the manner in which the same is to be or
may be performed or carried into practical effect, we would have it
understood that we lay no claim to the furnace nor to the arrangement
of its flucs, but what we do claim is, the construction and use of per-
forated bricks or blocks having butt" and socket" joints, as herein
described and shown by Drawings, when the bricks or blocks so made are

page_text: employed for the purpose of annealing wire and continuous strips of
metal, and for heating for the purpose of tempering the same.
In witness whereof, I, the said Michael Holroyd Smith, havo
for and on behalf of myself and the said Matthew Smith, here-
unto set my hand and scal, this Tenth day of February, in the
year of our Lord One thousand eight hundred and seventy-six.
Witness,
WALTER BRIERLEY,
Patent Agent,
Halifax & Blackburn.
