PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Removing Molten Slag, Scoria, and
other similar Materials from Furnaces.
I, WILLIAM HAWDON, of the Newport Iron Works, Middlesbrough-on-Tees, in
the County of York, Engineer, do hereby declare the nature of this invention to bo
as follows:-
This invention relates to improvements in apparatus for removing molten slag,
scoria and other similar materials from the furnace after the same have been with-
drawn, and depositing them into trucks or other receptacles, by means of which the
desired object is effected in an economical, speedy and convenient manner.
The apparatus, to the construction and arrangement of which this invention relates,
consists of an endless band or belt of wire rope, iron or steel links, or other suitable
contrivances, which band or belt passes, or works, over two or more series of wheels
or druns, to one of which series a rotary motion is given by means of an engine or
other prime mover. Attached to the outer face of the said band or belt is a continuous
succession of moulds, shapes or flat plates with upstanding edges, for the reception of
the molten material. The said moulds, shapes or plates are made of any suitable
material, preferably cast iron, and to prevent injury from expansion or contraction
they are made in parts or sections fitted together, as will be well understood. The
band is so arranged that the upper half thereof will, after the moulds, shapes, or
plates, have received the molten material, dip into a reservoir of water taking with it
the said moulds, shapes or plates whereby the same are cooled on their journey to the
end series of wheels or drums.
The action of the apparatus is as follows:-
The molten slag, scoria or other similar material flows from the furnace down a
channel or runner into the moulds or shapes or on to the plates, as the same are

page_text: carried past the lower end of the channel or runner by the before mentioned
travelling band or belt, the moulds, shapes or plates and their contents are then
dipped, as they travel along with the band or belt, into water and cooled, as herein-
before described, and as the band or belt turns round the end series of wheels or
drums, the moulds shapes or plates are tilted and turned over, and the contents thereof
are deposited into trucks or other receptacles arranged to receive them.
In some cases, instead of employing only one endless band or belt, I use two or
more such bands or belts the same being constructed and arranged, and furnished,
with moulds, shapes or plates in the manner hereinbefore described.

I, WILLIAM HAWDON,. of the Newlands, Middlesbrough-on-Tees, in the County of
York, Engineer, 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 :-
My said invention relates to improvements in apparatus for removing molten slag,
scoria and other similar materials from furnaces, after the same have been withdrawn,
cooling them and depositing them into trucks or other receptacles, by means of which
the desired object is effected in an economical, speedy and convenient manner.
The apparatus, to the construction and arrangement of which this invention relates,
consists of one or more endless bands or belts of wire rope, iron or steel links, or
other suitable contrivances which bands or belts pass, or work, over two or more
series of wheels or drums, to one of which series a rotary motion is given by means
of an engine or other prime mover. Attached to the outer face of the said bands or
belts, is a continuous succession of moulds, shapes or flat plates with upstanding
edges, for the reception of the molten material. The said moulds, shapes or platos
are made of any suitable material, preferably cast iron, and, to prevent injury from
expansion or contraction, they are made in parts or sections fitted together, as will
be well understood. The before mentioned endless bands or belts are so arranged
that the upper portion thereof will, after the moulds, shapes or plates have received
the molten material, dip into a reservoir of water taking with it the said moulds,
shapes or plates, whereby the latter and their contents are ecoled on their journey to
the end series of wheels or drums. The said reservoir is supplied with a continuous
flow of water, and this is, by preference, obtained from a perforated pipe, arranged
above, from which the water flows in a series of jets on to the upper faces of the
moulds, shapes or plates and the contents thereof, and thence into the reservoir, suitablo
channels being provided for the escape of the overflow.
I will now proceed to refer to the accompanying drawings from which the nature
of my said invention will be more clearly understood. The same letters of reference
indicate like parts in all the Figures. Figure 1. is a longitudinal view of an
apparatus constructed and arranged in accordance with this invention. A. A. are the.
endless bands or belts, C. is a series of wheels or drums over which one bend or loop
of each endless band or belt passes, and the shaft of the said series of wheels or
drums is driven through the medium of the primary driving shaft B; E. is a series.
of wheels or drums over which the other bend or loop of each endless band or belt
passes; D. is a water reservoir, which is shown in section; F. is a channel or runner
through which the molten slag, scoria or other materials flow and thence fall into the
moulds or shapes I. which are fixed on the endless bands or belts A; F' is receptacle
into which the cooled material is discharged from the said moulds or shapes as the

page_text: bands or belts travel round the series of wheels E; G. are rollers or pulleys serving
as guides and carriers for the lower portion of the bands or belts. H. are perforated
pipes from which water issues to assist in cooling the material, and one of which
provides a continuous supply to the reservoir D. The bearings of the shaft of the
series of wheels or drums E. are connected to one end of the rod or links N. the
outer end of which is attached to the screw M, and, into a worm wheel L. attached
to a scrow nut on the latter, gears a worm on the shaft J, the said screw nut and
worm wheel L. are arranged on the screw M. fixed on a bracket bearing through
which the end of the same screw M. passes. By turning the shaft J. the axle of the
shaft of the wheels or drums E. is caused to slide one way or the other in suitable
bearings and thereby the distance between the two series of wheels or drums C.
and E. is lengthened or shortened as required, this admits of the easy adjustment of
the hands or belts. Figure 2. is a transverse section of one form of mould or shape
which is suitable for the purpose of this invention, Figures 3. and 4. are respectively
longitudinal section and top view of three moulds or shapes secured in position on
the bands or belts, which are here shown composed of links. Figures 5. and 6. are
detached top views of a mould or shape made up of sections or parts as shown, and
Figures 7. and 8. are respectively longitudinal section and plan of several moulds
or shapes which are of another form and are also composed of sections or parts as
shown.
The action of the apparatus is as follows:-
The endless bands or belts A. are caused to travel in the direction indicated by the
arrow a, and at a portion of their journey they are arranged to dip, with the moulds
or shapes, which have been filled or partially filled with the molten slag, scoria or
other material flowing from the channel or runner F, into the reservoir 1). whereby
the said moulds or shapes and the contents thereof are cooled, as the bands or belts
pass over the series of wheels or drums E. the moulds or shapes are tilted and turned
over and the contents thereof discharged into the receptacle I".
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The construction and arrangement of the apparatus consisting of a series of moulds
or shapes or plates carried by an endless band or belt for removing molten slag,
scoria and other materials from furnaces and discharging them into receptacles
arranged at a distance, such materials being cooled during transit, substantially as
herein before described.
