IMPROVEMENTS IN CASTING RAILWAY CHAIRS, AND IN THE MANUFACTURE OF OTHER CASTINGS
Year: 1857

page_text: LETTERS PATENT to Thomas Howard Head and Joseph Wright, of the
Teesdale Iron Works, Stockton-on-Tees, Engineers and Ironfounders, for
the Invention of "IMPROVEMENTS IN CASTING RAILWAY CHAIRS, AND IN THE
MANUFACTURE OF OTHER CASTINGS."
Sealed the 11th September 1857, and dated the 21st March 1857.
PROVISIONAL SPECIFICATION left by the said Thomas Howard Head
and Joseph Wright, at the Office of the Commissioners of Patents,
with their Petition, on the 21st March 1857.
We, THOMAS HOWARD HEAD and JOSEPH WRIGHT, of the Teesdale Iron
Works, Stockton-on-Tees, Engineers and Ironfounders, do hereby declare the
nature of the Invention for "IMPROVEMENTS IN CASTING RAILWAY CHAIRS, AND IN
THE MANUFACTURE OF OTHER CASTINGS," to be as follows:-
In the method of moulding chairs and other castings in ordinary use two
difficulties arise, one being the labour required in moving the boxes from one
operation to the other, and another the labour required in turning them over.
Various methods are employed to obviate these difficulties.
By our Invention we effect the first object by means of a moveable welb,
working on rollers at each end, and consisting of small bars of iron fixed on a
chain at a few inches apart, the ends of these pieces working in a guide card
on the table at which the men work. On the ramming-up plate is cast or
fitted a small pin, which, when the ramming-up plate is upon the table,

it is required. When it is required to be stopped, a small lever is risen above
the level of the table, worked by an excentric shaft and forming an inclined
plane, up which the welb pulls the plate till the pin clears the welb (which is
always moving), and by lowering the handles the pin is again connected with
the welb, and moves with the box and the patterns to the next operator.
There are two trunnions cast upon the box, which passes between the
wheels, the ramming-up board being fastened to it by means of hasps. On
these wheels are two pockets, which take hold of the trunnions on the boxes,
lifting the box and bottom board together; and on arriving at the greatest
height, the box is tipped by means of a piece projecting from the standards,
and lowered again by the wheels on to the table, where it is again connected
by the means before described on to the moveable welb.
This form of arrangement is capable of variation; it might be in the form
of a circular moveable surface or turntable, or any other method for taking
the boxes away without the expenditure of manual labour.
Variations inay
also be adopted for lifting the boxes by the trunnion and turning them over.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Howard Head and Joseph Wright in the Great
Seal Patent Office on the 21st September 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
HOWARD HEAD and JOSEPH WRIGHT, of the Teesdale Iron Works, Stockton-
on-Tees, Engineers and Ironfounders, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of March, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Thomas Howard Head and Joseph Wright, Her special licence that
we, the said Thomas Howard Head and Joseph Wright, our executors,
administrators, and assigns, or such others as we, the said Thomas Howard
Head and Joseph Wright, our executors, administratore, 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 "Im-
PROVEMENTS IN CASTING RAILWAY CHAIRS, AND IN THE MANUFACTURE OF OTHER

page_text: CASTINGS," upon the condition (amongst others) that we, the said Thomas
Howard Head and Joseph Wright, our executors or administrators, by an
instrument in writing under our or their hands and seals, or under the hand
and seal of one of us or them, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, 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 Thomas Howard Head, on behalf of
myself and the said Joseph Wright, do hereby declare the nature of the said
Invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement thereof, that is
to say -
In the method of moulding chairs and other castings in ordinary use two
difficulties arise, one being the labour required in moving the boxes from one
operation to the other, and another the labour required in turning them over.
Various methods are employed to obviate these difficulties. By our Inventien
we effect the first object by means of a moveable webb, working on rollers at
each end, and consisting of small bars of iron fixed on a chain at a few inches
apart, the ends of these pieces working in a guide cast on the table at which
the men work. On the ramming-up plate is cast or fitted a small pin, which,
when the ramining-up plate is upon the table, catches in the moveable webb,
and draws it from its present position to where it is required. When it
is required to be stopped, a small lever is risen above the level of the table,
worked by an eccentric shaft and forming an inclined plane,up which the welb
pulls the plate till the pin clears the webb (which is always moving), and by
lowering the handles the pin is again connected with the webb,and moves with
the box and the patterns to the next operator. There are two trunnions cast
upon the box, which passes between the wheels, the ramming-upboard being
fastened to it by means of hasps. On these wheels are two pockets, which take
hold of the trunnions on the boxes, lifting the box and bottom board together;
and on arriving at the greatest height the box is tipped by means of a piece
projecting from the standards, and lowered again bythewheels on to the table,
where it is again connected by the means before described on to the moveable
webb.
This form of arrangement is capable of variation; it might be in the form of
a circular moveable surface or turntable, or any other method for taking the
boxes away without the expenditure of manual labour. Variations may also
be adopted for lifting the boxes by the trunnions and turning them over.

page_text: And in order that our said Invention may be most fully understood and
readily carried into effect, we will describe the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
A is the moveable webb, working on rollers B at each end. Details of the
webbare shewn half size; C being the pins to work in guide cast on table,

webb; F, levers and slides connecting or disconnecting the box or plate with
the webb at the will of the opperator; G,self-acting slide for throwing box out
gear H, eccentric for working levers F; I, trunnions cast on box K;

In witness whereof, I, the said Thomas Howard Head, have hereunto
set my hand and seal, this Nineteenth day of September, in the year
of our Lord One thousand eight hundred and fifty-seven.
