page_text: LETTERS PATENT to Thomas Howard Head, of Stockton-on-Tees, in the
County of Durham, Engineer, and Henry Smith, of the same Place,
Foreman, for the Invention of "IMPROVEMENTS IN MOULDING, AND IN
MACHINERY EMPLOYED THEREIN."
Sealed the 16th September 1864, and dated the 23rd March 1864.
PROVISIONAL SPECIFICATION left by the said Thomas Howard Head
and Henry Smith at the Office of the Commissioners of Patents, with.
their Petition, on the 23rd March 1864.
We, THOMAS HOWARD HEAD, of Stockton-on-Tees, in the County of
Durham, Engineer, and HENRY SMITH, of the same Place, Foreman, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MOULDING, AND IN MACHINERY EMPLOYED THEREIN," to be as follows:-
This Invention consists in moulding pipes, railway chairs, wheels, and other
castings in manner and by the machinery hereafter described.
In moulding pipes the box in which the mould is made is fixed to a hori-
zontal bed plate, mounted on a frame. The pattern is fixed in the centre of
the horizontal bed plate on axes, which are supported in bearings, a toothed_
wheel is fixed to one of the axes, and is geared into by a pinion moved by a
crank handle or wheel. The moulding box is then put on the horizontal
bed plate, and the ramming performed in the ordinary way; when rammed
the pattern is revolved or turned half round through the toothed wheel and
pinion or other suitable gear till it comes to the clearance on each side of the

page_text: pattern, which will leave the mould clear. By this means the mould is
finished before it is taken off the horizontal bed plate. The box is then taken
off, and the pattern turned back to its place; the other part of the box is
then proceeded with in the same way as the first. This apparatus is fixed on
wheels, so that it can be moved along a pipe bank, or it can be made a
fixture.
The apparatus for moulding other castings consists of a bed plate or table
fitted with a sliding frame inside, on which the patterns are fixed, and which
is made to slide up and down the table inside by means of a. screw, lever, or
otherwise. The table or bed plate is fixed on axes, which are supported on
uprights. The moulding box is fixed to the bed plate or table, and the
ramming is performed in the ordinary way. The bed plate or box, with the
patterns, is then turned over on the axes, which are fixed on one side of the
table or bed plate. On the other side of the table or bed plate a balance
weight is fixed, so that the turning over may be easily effected.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Howard Head and Henry-Smith in the Great Seal
Patent Office on the 23rd September 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
HOWARD HEAD, of Stockton-on-Tees, in the County of Durham, Engineer,
and HENRY SMITH, of the same Place, Foreman, send greeting.

Patent, bearing date the Twenty-third day of March, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Thomas Howard Head and Henry Smith, Her special licence that we,
the said Thomas Howard Head and Henry Smith, our executors, adminis-
trators, and assigns, or such others as we, the said Thomas Howard Head and
Henry Smith, our 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 MOULDING; AND IN MACHINERY EMPLOYED, THEREIN," upon the condition
(amongst others) that we, the said Thomas Howard Head and Henry Smith,
or one of us, our executors or administrators, by an instrument in writing

page_text: under our, or their, or one of our or their hands and "seals, "should par-
ticularly describe and ascertain the. nature of the said Invention, 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 month's next and immediately
after the date of the said Letters Patent.*
..I
:
NOW KNOW YE, that we, the said Thomas Howard Head and Henry
Smith, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, reference being had to the
Drawings hereunto annexed, that is to say :-
This Invention consists in moulding pipes, railway chairs, wheels, and other.
castings in manner and by the machinery hereafter described..
In moulding pipes the box in which the mould is made is fixed to a hori--
zontal bed plate mounted on a frame. The pattern is fixed in the centre of
the horizontal bed plate on axes which are supported in bearings; a toothed
wheel is fixed ito.one of the axes, and is geared into by a pinion moved by a
crank handle or wheel. The moulding box is then put on the horizontal bed
plate, and the ramming performed in the ordinary way; when rammed, the
pattern is revolved or turned half round through the toothed wheel and
pinion, or other suitable gear, till it comes to the clearance on each side of the
pattern, which will leave the mould clear. By this means the mould is
finished before it is taken off the horizontal bed plate: The box is then taken
off and the pattern turned back to its place. The other part of the box is
then proceeded with in the same way as the first. This apparatus is fixed on
wheels, so that it can be moved along a pipe bank, or it can be made a
fixture. :*
The apparatus for moulding other castings consists of a bed plate or table
fitted with.a.sliding frame inside,-on-which-the-patterns are fixed, and which.
is made to slide up and. down the table inside by means of a screw, lever, or
otherwise. The table or bed plate is fixed on axes, which are supported on
uprights. The moulding box is- fixed to the bed plate or table, and the.
ramming' is' performed in the ordinary way. The bed plate or box, with the:
patterns, is then turned over on the. axes, which are fixed on one side of:
the table or bed plate. On the other side of the table or bed plate a balance.
weight is fixed, so that the turning over may be easily effected:

elevation of a machine for. making pipe moulds.constructed according to our
Invention; Figure 3 is a section through the line A, B, of Figure 1; and
Figure 4:a section through the. line C, D,.of Figure 2. a, a, is a horizontal

page_text: bed plate, mounted on a frame b, b; c is the pattern fixed in the centre of the
bed plate a, a, on axes d, d, which are supported in bearings e, e; a toothed
wheel fis fixed to one of the axes d, and is geared into by a pinion g, moved
by a crank handle h. This toothed wheel, pinion, and crank handle are shown
detached in Figure 5. i, i, is the moulding box, which is put on the bed
plate a, a. After the ramming has been performed the pattern c is caused to
revolve or turned. half round by means of the handle h and toothed gearing
till it comes to the clearance on each side of the pattern, whereby the mould
will be left clear. The mould is thus finished before it is taken off the bed
plate a, a; the box i is then taken off, and the pattern c turned back to its
place; the other part of the box is then proceeded with in the same manner
as the first. j,j, are wheels fixed to the apparatus in order that it'
may be
moved if required.
Figure 6 is a vertical section of a machine for making moulds for railway
chairs and other castings. a is a bed plate or table, and 6 a frame fitted to
slide inside the bed plate a; c is the pattern fixed to the frame 6 by means of
screw guide rods d, d. The frame 6 is made to slide up and down the bed
plate a by means of a screw e furnished with a handle f. The bed plate a is
free to turn on axes 9, 9, (Figures 7 and 8) supported on uprights h, the
moulding box i is fixed to the bed plate a, and the ramming is performed in
the ordinary manner. The bed plate a, with the pattern c, is then turned
over on the axes g, g, by means of handles j, j, into the position shewn in plan
in Figure 7. k is a balance weight to assist in turning over the bed plate;
when turned over, the mould box i rests upon a travelling carriage'l, Figure 8,
the handlef is then turned to remove the pattern c from the mould, the box i
is unfastened from the bed plate a, and the bed plate is turned back on its
axes g, g, into its first position to receive another mould box.

making two moulds for railway chairs on the same frame, similar letters to
those in Figures 6 and 7 refer to similar parts.
Having now described and particularly ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that
we do not confine ourselves to the precise details or arrangements herein-
before described, as many variations may be made therefrom without departing
from the main features of our Invention; and that we claim,-
First, making moulds for casting pipes, substantially in manner and by the
machinery herein-before described, and illustrated in Figures 1 to 5 of the
accompanying Drawings.
Second, making moulds for casting railway chairs and other castings,.
