PROVISIONAL SPECIFICATION.
Combined Pig-Iron Carrier and Breaker.
1 REGINALD BURSLEM SPARROW Greenscoe House Askam-in-Furness Ironmaster
do hereby declare the nature of this invention to be as follows:-
:―
This invention consists of one or more endless bands (which may be made of iron or
steel wire, or links, sheets, or other material) and will be trained on rollers fixed along
the pig bed, and driven at any desired speed, on which can be placed the pig iron, the
bands will deliver the same to an upright gaff, on which will be working one or more
endless chains, links, or bands, to which will be attached suitable hooks, these will
pick the pig up off the horizontal travelling bands and carry it to any desired beight,
when it will deliver it over the top roller or rollers, it will then fall down on the other
side on to a breaker (which may be of the usual diamond shape, or other design and
made of either steel or iron). The pieces may then fall on to the ground, delivered
into shoots, or on to a revolving table, and so carried round to any desired
position for a man to examine the fracture and dispose of them in the ordinary
way.
The whole will be actuated by steam or other power and the horizontal & vertical
bands geared to any desired speed, and in the case of more than one being at work,
friction or other clutches will be fixed, so that any one may be stopped independant
of the other when not wanted to be in use.

COMPLETE SPECIFICATION.
Combined Pig-Iron Carrier and Breaker.
I REGINALD BURSLEM SPARROW Ironmaster, Greenscoe House Askam in Furness
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:
This invention relates to apparatus for conveying pig iron horizontally to a con-
venient point at which it may be elevated to an altitude sufficient for ensuring the
breaking of "pigs" when released from the elevator and allowed to fall across
a Vee shaped hardened steel bed or anvil firmly secured at the base of the
elevator.
For this purpose I provide an endless band preferably in the form of two endless
chains carried and guided in their travel by any convenient number of grooved pulleys
arranged in pairs at a suitable distance apart to agree with the length of the
"pigs to be dealt with. The pair of such pulleys the furthest removed from the
elevator are mounted upon their axle which is free to rotate in bearings fitted in
guides upon a suitable bed so that they may be moved by means of a screw nut with
winch handles in order to provide for straining the band or chains in a manner to
afford a sufficiently rigid support for the superincumbent weight of the " pigs" to
be transported thereon. This band or chains may be driven at any required speed
to deliver the pigs" regularly to an upright gaff on which endless chains, links
or hands are put in motion so as to receive from the horizontal endless band or
chains the "pigs" to be elevated by means of suitable hooks to the upper extremity
of the gaff in which position they are carried horizontally over rollers around which
the elevator band or chains and hooks pass and then releasing the "pigs" at this
altitude allow them to fall alternately upon a breaker which may be of the usual
".

page_text: The broken pieces may then fall on to the ground or be conveyed into suitable shoots
for delivering the broken pieces at one fixed point or tlicy may fall by way of a
shoot on to a revolving table and so be carried round to any desired position in
which they may safely be examined as to the nature of the fracture and then be
disposed of in the ordinary way.
Both the horizontal conveyor and the inclined vertical elevator may be set in
motion by means of geared wheels suitably speeded for conveying the motion from
any ordinary source of power and may be set in motion or be stopped by the
employment of a clutching device ordinarily employed for stopping and starting
heavy machinery.
DESCRIPTION OF THE DRAWINGS.
In the accompanying drawings the same reference letter indicates the same part in
all the figures.
Figure 1 is a side elevation of the complete apparatus partly in section. Figure 2
is a plan of the gaft or clevator with part of the horizontal conveyor extending there-
from and Figure 3 is a sectional view of the "breaker" or anvil taken at the line a y
in Figure 1. A is the screw fitted with winch handles by means of which the screw B may
be operated so as to put the required tension upon the endless chains C of the horizontal
conveyor which are supported upon any convenient number of grooved pulleys D one
pair of which may be driven by the geared wheel E and pinion F controlled by an
ordinary clutch arrangement for driving or stopping as desired from the shaft G
which may be driven from any source of motive power.
Upon the countershaft H to which are keyed the two grooved pulleys D giving
motion to the horizontal conveyor there are also keyed two pulleys J having "flats
thereon corresponding with similar "flats" formed upon a pair of similar pulleys K
upon which rest successively the endless links L of which the elevator is formed each
link L being fitted with a projecting hook M constructed to fold in one direction so as
to avoid injury thereto during the fall of the "pigs" from the upper part of the elevator
on to the breaker or anvil N beneath.
From this position the fragments pass by way of a shoot P to any required point
or they may fall by way of this shoot on to a horizontal table set in continuous
motion about a vertical axis and so be carried round to any desired position in
which they may safely be examined as to the nature of the fracture and then be
disposed of in the ordinary way.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The combination of a horizontal conveyor with a vertically inclined elevator for
the purpose of conveying, elevating, releasing, breaking and distributing the fractured
portions of pig iron substantially as described and illustrated by the accompanying
drawings.
