An Improved Apparatus or Elevator for use in Charging Furnaces.
We, HENRY TOMKINS, Contractor; CHARLES JOHN BAGLEY, General Manager;
LLEWELYN ROBERTS, Works Manager; and the MooR STEEL AND IRON COMPANY
LIMITED, all of the Moor Steel and Iron Works, Stockton-on-Tees, in the County
of Durham, do hereby declare the nature of this invention. to be as follows:-
This invention relates to an apparatus of the endless band or belt type for use
as an elevator of pig-iron and the like material to be charged into an open hearth
furnace.
As will be seen from the following description the apparatus is adapted for
use generally as an elevator of pig-iron and the usual furnace charging material
but the object more especially in view in designing the apparatus in question is
to provide a continuous elevation of such material from one level say the ground
or floor line level on which the furnace is built to a higher level from which the
said material can be dropped into a shoot for charging an open hearth furnace
by gravity in the manner described in the Specification of our invention of
Improvements in means and appliances for charging open hearth furnaces
No. 13754 of 1897 so that the full advantage and economy of using a shoot as
therein described for charging the furnace by gravity may be available in cases
in which the material must be first elevated to the higher level and position from
which it is to fall.
"'
"
The apparatus consists of an endless band or belt made up of a continuous
system of segmental plates connected together by hinged joints and adapted to
pass over flat sided drums such as hexagonal drums driven by power as from
an engine shaft. On each such segmental plate is mounted a bucket or trough
which is carried round the drums, as the belt travels the apparatus is set to a
suitable incline so that the buckets are in a position to hold the furnace charging
material when travelling along the ascending side of the apparatus and are in-
verted as soon as the top drum is surmounted. A foot plate is placed near the
lower end or bight of the belt and is so set and inclined to the elevator that the
material to be conveyed up to the elevator is charged onto it and then slides down
into bucket after bucket as the belt travels past the edge thereof.
Provision is made to prevent the belt running back unless lowered under the
control of the engine or motor by which it is driven.

by the following statement:-
·
This invention relates to an apparatus of the endless band or belt type for use
as an elevator of pig iron scrap and the like material to be charged into an open
hearth furnace.
As will be seen from the following description the apparatus is adapted for
use generally as an elevator of pig iron and the usual furnace charging material
but the object more especially in view in designing the apparatus in question is
to provide a continuous elevation of such material from one level say the ground
or floor line level on which the furnace is built to a higher level from which the
said material can be dropped into a shoot for charging an open-hearth furnace
by gravity in the manner described in the Specification of our invention of
"Improvements in means and appliances for charging open-hearth furnaces."
No. 13754 of 1897; so that the full advantage and economy of using a shoot as
therein described for charging the furnace by gravity may be available in cases
in which the material must be first elevated to a higher level and position from
which it is to fall.
We will in describing the invention refer to the annexed drawing in which
the duct or shoot is shown in position for charging the furnace together with the
elevator for conveying the charging materials to the requisite elevation for drop-
ping them into the shoot.
a is the chamber or hearth of the furnace and b the charging door; c is the
charging shoot into which pig iron and scrap are thrown to be carried down the
shoot by gravity and discharged into the furnace a. The elevator d consists
of an endless band or belt made up of a continuous system of segmental plates e
connected together by hinged joints and adapted to pass over flat sided drums f f¹
such as hexagonal drums driven by power as from an overhead driving shaft g.
On each such segmental plate e is mounted a bucket or trough h which is carried
round the drums f f as the belt travels. The apparatus is set to a suitable incline
as shown so that the buckets h are in a position to hold the furnace charging
material when travelling along the ascending side of the apparatus, and are
inverted as soon as the top drum f is surmounted. A foot plate is placed near
the lower end or bight of the belt and is so set and inclined to the elevator that
the material to be conveyed up the elevator is charged on to it, and then slides
down into bucket after bucket as the belt travels past the edge thereof. The
elevator d is made to travel from door to door of the furnace so as to change the
line or fall of material charged into the shoot c, the shoot travelling from door
to door of the furnace in like manner to the elevator. Where the structural
arrangement of the works admits of it, the shoot and elevator may travel from
furnace to furnace. For this purpose the elevator is mounted at its lower end
on a bogie winch j, and at its upper end on an overhead travelling bogie j¹, the
whole being operated by the hand levers & through suitable gearing. is a paul,
and a ratchet wheel to prevent the belt running back unless lowered under the
control of the engine or motor by which it is driven.

page_text: Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is: -
1. In an apparatus or appliance for charging open-hearth steel melting fur-
naces, the combination with a duct or shoot such as c, which by its shape and
position is adapted to charge the materials into the furnace by the momentum
derived from gravity, of an endless belt elevator such as d furnished with a series
of buckets h, which discharge their contents one by one into the shoot c, whether
as a fixture or with the shoot travelling from door to door of the furnace and the
elevator travelling in like manner to the shoot, substantially as hereinbefore
described with reference to the accompanying drawing.
2. An endless band elevator such as d furnished with a series of buckets h which
discharge their contents one by one in a manner adapted for charging a shoot such
as c and in combination therewith a foot plate i for continuously charging the
said buckets, the said elevator being either a fixture or mounted on a bogie winch
to be used and operated substantially as hercinbefore described and illustrated in
the accompanying drawing.
