IMPROVEMENTS IN APPARATUS USED WHEN CASTING IRON OR OTHER METAL
Year: 1862

page_text: LETTERS PATENT to Henry Smith, of the Teesdale Iron Works, Stockton-
on-Tees, in the County of Durham, for the Invention of "IMPROVEMENTS
IN APPARATUS USED WHEN CASTING IRON OR OTHER METAL."
Sealed the 5th September 1862, and dated the 1st April 1862.
PROVISIONAL SPECIFICATION left by the said Henry Smith at the Office
of the Commissioners of Patents, with his Petition, on the 1st April
1862.
I, HENRY SMITH, of the Teesdale Iron Works, Stockton-on-Tees, in the
County of Durham, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN APPARATUS USED WHEN CASTING IRON OR OTHER METAL," to be
as follows:-
This Invention has for its object improvements in apparatus used when
casting iron or other metal. For this purpose a carriage or truck is used
with upright end frames suitable for receiving a ladle between them. At the
upper part of these end frames there are bearings for an axis, on which axis
there is fixed a barrel, on which is wound a chain to which the ladle is
suspended. The axis is arranged nearer to one side of the carriage than the
other by preference, but it can be placed in the centre if required, and the end
framings are strongly braced or connected together. On the axis is fixed a

page_text: screw or worm wheel, which receives motion from a screw or worm on a
suitable axis, on which is fixed a handle or hand wheel, by which motion is
given to the axis of the screw or worm, and consequently to the barrel, in
order to raise or lower the ladle, or it may be raised or lowered by gearing or
ratchet wheel and lever. To facilitate the tilting of the ladle the tilting bar
is received into hooks or bearings at the two ends of the arched frame or bar
which is suspended by the chain on the barrel. The four wheels of the truck,
or carriage are suitable for running on a rail or tramway laid down between
the cupola or other melting furnace and the place where the moulds are
situated.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Smith in the Great Seal Patent Office on the 30th
September 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
SMITH, of the Teesdale Iron Works, Stockton-on-Tees, in the County of
Durham, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of April, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Henry Smith, Her special licence that I, the said Henry Smith, my
executors, administrators, and assigns, or such others as I, the said Henry
Smith, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
APPARATUS USED WHEN CASTING IRON OR OTHER METAL," upon the condition
(amongst others) that I, the said Henry Smith, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Smith, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,

page_text: to be particularly described and ascertained in and by the following statement
thereof, that is to say:-
This Invention has for its object improvements in apparatus used when
casting iron or other metal. For this purpose à carriage or truck is used
with upright end frames, suitable for receiving a ladle between them. At the
upper part of these end frames there are bearings for an axis, on which axis
there is fixed a barrel, on which is wound a chain, to which the ladle is
suspended. The axis is arranged nearer to one side of the carriage than the
other by preference, but it can be placed in the centre if required, and the end
framings are strongly braced or connected together. On the axis is fixed a
screw or worm wheel which receives motion from a screw or worm on a
suitable axis, on which is fixed a handle or hand wheel, by which motion is
given to the axis of the screw or worm, and consequently to the barrel, in
order to raise or lower the ladle, or it may be raised or lowered by gearing or
ratchet wheel and lever. To facilitate the tilting of the ladle the tilting bar
is received into hooks or bearings at the two ends of the arched frame or bar,
which is suspended by the chain on the barrel. The four wheels of the truck
or carriage are suitable for running on a rail or tramway laid down between
the cupola or other melting furnace and the place where the moulds are
situated.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a side elevation of a truck or carriage and apparatus con-
structed and combined therewith according to my Invention; Figure 2 shows
an end view; and Figure 3 shews a plan of the saine.
A, A, are two end frames, which are connected to and carried by the axles
C, C, which are connected and framed together by the parts B, B, or by any
convenient arrangement for retaining the end frames securely in position. On
the top of the side frames A are bearings for the axis D, on which axis is a
screw or worm wheel E, which receives motion from a screw or worm E', the
axis of which receives motion by means of the crank handle E', which is
retained from movement when desired' by the chain and hook E³. On the
axis D is fixed a barrel E, on which is wound the chain by which the ladle is
suspended from the barrel. It should be stated that although I believe that a
screw or worm combined with a screw or worm wheel is the most convenient
method of giving motion to the axis D, other gearing or apparatus may be
used for this purpose. F is an arched frame or bar, in the ends of which the

page_text: tilting bar G is received in hooks or other suitable bearings. At the upper
part of the arched bar F is a swivel hook or eye, to which the end of the
chain is attached; M is a folding stop or catch, which is forked, so as to pass
on both sides of the arched bar; M₁ is another guard or stop, which prevents
the ladle swinging when the carriage or truck is being moved along a tram or
railway between the furnace and the moulds; H is the ladle; L, L, are the
wheels on which the carriage or truck is moved on a tram or railway to and
from the furnace and the moulds.
Having thus described the nature of my Invention and the manner of per-
forming the same, I would have it understood that I make no claim to any of
the mechanical parts separately, but what I claim is the combination herein
described.
In witness whereof, I, the said Henry Smith, have hereunto set my
hand and seal, this 31st day of July, in the year of our Lord One
thousand eight hundred and sixty-two.
HENRY SMITH. (L.S.)
