IMPROVEMENTS IN AND APPLICABLE TO PUDDLING FURNACES
Year: 1877

page_text: LETTERS PATENT to Thomas Gidlow, of Hollywood, Heaton, in the County of
Lancaster, Iron Master, and James Abbott, of Ince, in the said County of
Lancaster, Manager of Works, for the Invention of "IMPROVEMENTS IN AND
APPLICABLE TO PUDDLING FURNACES."
Sealed the 28th May 1878, and dated the 8th December 1877.
PROVISIONAL SPECIFICATION left by the said Thomas Gidlow and James
Abbott at the Office of the Commissioners of Patents on the 8th December
1877.
THOMAS GIDLOW, of Hollywood, Heaton, in the County of Lancaster, Iron Master,
and JAMES ABBOTT, of Ince, in the said County of Lancaster, Manager of Works.
"IMPROVEMENTS IN AND APPLICABLE TO PUDDLING FURNACES."
This Invention relates more especially to improvements on the vibrating, rocking,
or oscillating puddling furnace, for which we obtained Her Majesty's British Letters
Patent, No. 2018, of the year 1877, and has for its object to facilitate the pro-
duction of puddled iron or steel in large quantities, and to increase the durability
of certain parts of the furnace. For the above purposes we proceed as follows:-
First. We construct the vibrating, rocking, or oscillating furnace, with an opening
or openings through which a combustible gas or combustible gases and air may be
admitted together or separately into the said furnace and ignited. The burning
gases act directly on the iron or steel to be treated, and no fire-grate is
required.
Second. We connect the pipes or tubes conveying the combustible gas or com-
bustible gases and air, to the vibrating, rocking, or oscillating furnace, by means of
sliding or rocking or other joints, so as to allow the way or passage for the gas or
gases and air to be kept tight whilst the furnace is in motion.
.
Third. We construct vibrating, rocking, or oscillating furnaces, whether heated
by solid or liquid or gaseous fuel, when of large size, with two or more movable or
flexible necks leading to the chimney or flue, or one neck divided into two or more
divisions internally.

page_text: Fourth. We construct or fit the neck or necks of a rocking, vibrating, or oscil-
lating furnace with a damper or dampers, so that the passage of the heated gases
and products of combustion, through the furnace to the chimney or flue, may be
under controul.
Fifth. We construct the bridge of the rocking, vibrating, or oscillating furnace
between the fire-grate and the hearth, or the ends of the hearth, against which the
molten metal is thrown by the motion of the furnace, hollow, so as to allow of the
circulation of air or other cooling medium therethrough.
Sixth. We construct furnace bridges and other parts of furnaces exposed to very
high temperatures in the following novel manner:-The bridge is constructed or
formed of a hollow metal casing surrounded with brickwork. A pipe perforated on
its upper surface is led into or through such hollow metal casing, and jets of water
are caused to pass out through the openings of the said pipe, and impinge against
the internal top and sides of the bridge. The steam produced by the action of the
heat on the said jets of water is allowed to pass through openings leading into the
furnace, and there mingle with the products of combustion. Any water not con-
verted into steam finds its way through openings leading to the ash pit.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Thomas Gidlow and James Abbott in the Great Seal Patent
Office on the 6th June 1878.
