I, JOHN HENRY DEWHURST, of 68, Attercliffe Road, Sheffield, in the County of
York, Mechanical Engineer, do hereby declare the nature of my said invention
to be as follows;―
Although my invention is applicable to ladles and ladle carriages which may
be employed for a variety of purposes, it is more particularly applicable where
they are employed for the removal of molten slag from blast furnaces, such as
are used for smelting iron ore or the like metallurgical processes.
The objects of my invention are, first, to construct such a ladle in cast metal
which shall be so built up in segments that worn or broken parts can be readily
removed and replaced by others, and secondly, to provide the means for tipping
or turning the ladle by power supplied from the locomotive or other engine em-
ployed for hauling or shunting the same.
I carry out my invention in the following manner.
I form the portion of the ladle to which the trunnions are affixed, separately
from the portions above and below it, thus, what may be called the waist or
hoop of the ladle with its trunnions, I form in one or more pieces of cast metal,
and provide with flanges on its upper and lower faces. To the lower flange I bolt
or otherwise secure the flange or flanges of the bottom or bowl of the ladle, which
may be made either in one piece of cast metal or in segments, and in like manner
to the top flange of the said waist or hoop I secure by bolts or otherwise the upper
part of the ladle either in one piece of cast metal or in segments.
On to one trunnion of the said ladle I fix a worm wheel and on the framework
of the carriage I provide pedestals or brackets for supporting a worm shaft pro-
vided with a worm to actuate the last named worm wheel. On the worm shaft
I likewise provide two chain drums or barrels one on each side of the worm and
I likewise provide at each end of the worm shaft two hand wheels by which the
ladle can be turned by hand when necessary. To each of the chain barrels pre-
viously mentioned I attach a chain, the chain, on the one barrel being wound up,
whilst that attached to the other barrel is allowed to lay slack in a locker pro-
vided for the purpose under or near to each barrel.
The action of the turning apparatus is as follows.
When the ladle carriage has been hauled or shunted to the place where
it has to be tipped, the chain from the barrel which is wound up is at-
tached to the locomotive, and the wheels of the carriage are blocked or
skidded, the locomotive is then detached from the carriage and allowed to run a
short distance away from it, thereby pulling and unwinding the chain from the
barrel, at the same time causing the barrel to revolve with the worm shaft, worm
and worm wheel, until the ladle is sufficiently tilted for its contents to be emptied.
The engine is then run back and attached to the other chain which by the process
last described has been wound on to its barrel. The locomotive, is again run away
from the carriage a short distance as before, when the motion is communicated to
the turning gear as already described, but in the reverse direction, and the ladle

process is again ready for use.
Improvements in Ladles and Ladle Carriages.
I, JOHN HENRY DEWHURST, of 68, Attercliffe Road, Sheffield, in the County of
York, Mechanical Engineer, do hereby declare the nature of my said invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:--
Although my invention is applicable to ladles and ladle carriages which may
be employed for a variety of purposes, it is more particularly applicable where
they are employed for the removal of molten slag from blast furnaces, such as
are used for smelting iron ore or the like metallurgical processes.
The objects of my invention are, first, to construct, such a ladle in cast metal
which shall be so built up in segments that worn or broken parts can be readily
removed and replaced by others. and secondly, to provide the means for tipping
or turning the ladle by power supplied from the locomotive or other engine em-
ployed for hauling or shunting the same.
My invention will be better understood on reference to the accompanying
4 sheets of drawings, in which,
Fig. 1, Sheet 1, is the side elevation of one of my improved cast metal ladles
built up in segments.
Fig. 2 is an end view of the same, and
Fig. 3 is a plan.
Fig. 4, Sheet 2, is a side elevation of one of my improved ladle carriages shew-
ing an ordinary wrot iron ladle mounted therein.
Fig. 5, Sheet 3, is an end view of the same, and
Fig. 6, Sheet 4, is a plan of the same.
The same letters refer to similar parts throughout the several views.
I carry out the first part of my invention in the following manner.
secure
I form the portion of the ladle to which the trunnions are affixed, separately
from the portions above and below it, thus, what may be called the waist or
hoop, A of the ladle with its trunnions B, I form in one or more pieces of cast
metal, and provide with flanges C, C', on its upper and lower faces. To the
lower flange I bolt or otherwise secure the flange or flanges of the bottom or
bowl, E, of the ladle, which may be made either in one piece of cast metal or in
segments, and in like manner to the top flange of the said waist or hoop
by bolts or otherwise the upper part of the ladle, F, either in one piece of cast
metal or in segments. The second part of my invention is applicable to ladles
constructed in cast metal, such as I have last described and illustrated in Figs. 1,
2 & 3, of Sheet 1, of the accompanying drawings, or it may be employed with
ladles constructed in wrot metal such as are commonly in use and such as are
illustrated in Figs. 4, 5, & 6, of the 2nd 3rd and 4th Sheets of the accompanying 4
drawings.
I carry out the second part of my invention in the following manner.
On to one trunnion of the said ladle I fix a worm wheel G, and on the frame-
work of the carriage, H, I provide pedestals or brackets, I, for supporting a worm
shaft, J, provided with a worm, K, to actuate the last named worm wheel. On 5

page_text: the worm shaft I likewise provide two chain drums or barrels, LL', one on each
side of the worm, K, and I likewise provide at each end of the worm shaft two
hand wheels, M, M', by which the ladle can be turned by hand when necessary.
To each of the chain barrels previously mentioned, I attach a chain, N, N¹, the
chain on the one barrel being wound up whilst that attached to the other barrel
is allowed to lay slack in a locker, o, provided for the purpose under or near to
each barrel.
The action of the turning apparatus is as follows.
When the ladle carriage has been hauled or shunted to the place where
it has to be tipped, the chain from the barrel which is wound up is at-
tached to the locomotive, and the wheels of the carriage are blocked or
skidded, the locomotive is then detached from the carriage and allowed to run a
short distance away from it, thereby pulling and unwinding the chain from the
barrel, at the same time causing the barrel to revolve with the worm shaft, worm
and worm wheel, until the ladle is sufficiently tilted for its contents to be emptied.
The engine is then run back and attached to the other chain which by the process
last described has been wound on to its barrel. The locomotive is again run away
from the carriage a short distance as before, when the motion is communicated to
the turning gear as already described, but in the reverse direction, and the ladle
is turned up or righted. The first chain which has become unwound in the
process is again ready for use.
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:
1. In a cast metal ladle employed for the removal of molten slag, molten metal,
or the like material from blast or other metallurgical furnaces the arrangement
and combination of parts and appliances by means of which such a ladle with its
trunnions may be built up in segments so that worn or broken parts,can be
removed and replaced by others in the manner and for the purposes substan-
tially as herein described and illustrated in Figs. 1, 2, and 3, of the first sheet of
the accompanying drawings.
2. In a ladle carriage employed for the removal of molten slag, molten metal, or
the like material from blast or other metallurgical furnaces, the arrangement and
combination of parts and appliances by means of which the tipping or turning
and righting of the ladle may be effected by power supplied from a locomotive or
other engine employed for hauling or shunting the same, in the manner and for
the purposes substantially as herein described and illustrated in Figs. 4, 5, and (
of the 2nd 3rd and 4th Sheets of the accompanying drawings.
3. In a ladle and ladle carriage employed for the removal of molten slag, molten
metal, or the like material from blast or other metallurgical furnaces, the arrange
ment and combination of parts and appliances by which the worm, worm wheel
and trunnions, for tipping or turning and righting the ladle are actuated, com-
prising the two chain drums or barrels, L, L', fixed on the worm shaft, J, one
on each side of the worm, K, the chains, N, N1, attached, one, to each of the last
named barrels so that the said chains may be pulled alternately by the loco-
motive or other engine employed for hauling or shunting the carriage, in the
manner and for the purposes substantially as herein described and illustrated in
Figs. 4, 5, and 6, of the 2nd, 3rd, and 4th Sheet of the accompanying drawings.
Dated this 27th day of September 1898.
