21 Park Street Barkerend Road Bradford (all in the County of York) Iron
moulder An IMPROVED METHOD OF MOULDING IN DRY OR GREEN SAND OF
ALL METALS OR THEIR ALLOYS AND IN APPARATUS THEREFOR
"
The object of our said invention is to effect improvements in moulding and is
applicable to the formation of articles in cast metal which have hitherto been
rarely if ever attempted to be so made and is more especially applicable to
sectional patterns such as casement and other windows palisadoes railings gates
terminals lamps and ornamental and open metal work generally.
We effect these improvements by piecing building up or putting together the
sand in sectional blocks one two or more sides of each block being impressed or
indented with the whole or some portion of the pattern such indentation forming
a portion of the matrix into which the molten metal is to be run.
A sufficient
number of these blocks or sections are placed together to form the entire casting
the usual apertures being provided to admit the molten metal and allow air to
escape.

page_text: The sectional blocks of sand are formed from patterns usually of wood and such
patterns are carefully formed with the design or a portion thereof facing or
impinging upon the sand. These patterns are sometimes placed in guide frames
with horizontal screws to draw them together in other cases the patterns are held
together with ordinary clamps and the sand is then placed in the pattern and
rammed in the ordinary manner by hand or otherwise with lifting irons for
removing the sand blocks and which after opening out the pattern are removed to
suitable places prepared for running the metal
In some cases we so form the mould that two or more castings may be made
from one pouring of similar or somewhat similar forms or patterns.
Our invention is applicable to circular curved angular zig zag and other castings
the sectional blocks for which are arranged to form when placed together the entire
mould therefor; the angles at the junctions of the blocks being arranged to accord
with the casting required

an Order of the Lord Chancellor, filed by the said Samuel Exley Seanor,
Johnson Hill, and John Butler in the Great Seal Patent Office on the
27th December 1883.
SAMUEL EXLEY SEANOR of East Street Leeds Hackle and Gill Pin maker
JOHNSON HILL of Low Baildon near Leeds, Pattern Maker and JOHN BUTLER of
21 Park Street Barkerend Road Bradford (all in the County of York) Iron
moulder " AN IMPROVED METHOD OF MOULDING, IN DRY OR GREEN SAND, OF
ALL METALS OR THEIR ALLOYS, AND IN APPARATUS THEREFOR"
The object of our said Invention is to effect improvements in moulding, and is
applicable to the formation of articles in cast metal which have hitherto been
rarely, if ever, attempted to be so made, and is more especially applicable to
sectional patterns such as casement, and other windows, palisadoes, railings gates,
terminals, lamps and ornamental and open metal work generally.
. We effect these improvements by piercing, building up, or putting together the
sand in sectional blocks, one, two or more sides of each block being impressed or
indented with the whole or some portion of the pattern, such indentation forming
a portion of the matrix into which the molten metal is to be run-A sufficient
number of these blocks or sections are placed together to form the entire casting:
the usual apertures being provided to admit the molten metal and allow air to
escapo.
The sectional blocks of sand are formed from patterns made of wood or other
suitable materials and such patterns are carefully formed with the design or a
portion thereof facing or impinging upon the sand. These patterns are sometimes
placed in guide frames with horizontal screws to draw them together; in other
cases the patterns are held together with ordinary clamps, and the sand is then
placed in the pattern and rammed in the ordinary manner by hand or otherwise
with lifting irons for removing the said blocks and which after opening out the
pattern are removed to suitable places prepared for running the metal
In some cases we so form the mould that two or more castings may be made
from one pouring, of similar or somewhat similar forms or patterns.
Our invention is applicable to circular, curved annular, zigzag and other castings,
the sectional blocks for which are arranged to form, when placed together, the
entire mould therefor, the angles at the junctions of the blocks being arranged to
accord with the casting required.
And in order that our said invention may be clearly understood reference is
hereby made to the accompanying drawings, wherein similar letters of reference
indicate corresponding parts in the several figures, and which drawings are intended
to indicate the mode of carrying our invention out in practice with respect to the
articles illustrated, as it is obvious that the variations and adaptations of which the
invention is capable, are very numerous.
In arranging our said invention for casting windows for Ecclesiastical and other
structures in one piece, such as that shown in Fig: 7, we use a sand mould as
shewn in Figs 1 and 2-Fig: 1 being a plan view and Fig: 2 a longitudinal
section of Fig: 1.
a is a small platform or table, formed of wood or other suitable material as
shewn, the construction being readily understood from the figures. On turning
the handle b the travelling nuts c. c approach toward or recede from one another
by means of the right and left hand screws d d on one shaft or spindle, e e are the
moulding pieces, usually, but not necessarily, formed of wood) having half of the

page_text: pattern of the sash bar or any other forms required carefully formed thereon. The
sand is filled in and rammed in the usual manner, after which the bandle b. is so
turned as to release the pattern. The block of sand is then removed and placed
in position for casting, with a number of similar blocks, laid together as shewn
in Fig: 3 When a sufficient number of blocks have been pieced together
the slightly varied forms required for the triangular panes in Fig: 7 with the
outside cores all round the above mentioned blocks and triangular panes containing
on their faces a half section joining up to the blocks already placed in position
which then forms a complete mould for such a casting, the usual gates being
provided for the entrance of the metal and exit of air.
Fig: represents in section portions of two blocks of sand with the impress of
the sash bar. Fig: 5 shews our method of casting two such windows in one
pouring, the two being afterwards broken away at their junction with f
Fig 6 represents our mode of carrying out our invention in moulding a bow
window, the section of which may of course be reversed for a convex window.
In casting a lamp as shewn in Figure 8 all in one piece the various portions
forming the entire mould, are placed in suitably formed core irons, one of which
is shewn in Fig: 9-Fig: 10 is a section on the line 1. 2 of Figure 9. Figures 13
and 14 are end views of Fig: 9 shewing the tabs in position
Fig 11 is an inside view of the upper part of the box with one of the cores
placed in position
Having thus particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we claim :-
:-
1 The method means and appliances for forming portions of the matrix, where
repetition sections are required, and building up the entire mould, for the
purposes and in manner substantially as hereinbefore described and shewn on the
drawings.
2. The mode or method of arranging, making and using skeleton or open
worked core irons constructed after the manner of that shewn in Figures 9. 10.
13 and 14, whereby light castings can be made with facility and in one piece,
substantially as herein before described and shewn on the drawings
3. The improved method of moulding, in dry or green sand, of all metals or their
alloys, substantially as hereinbefore described and shewn on the drawings.
In witness whereof I the said Samuel Exley Seanor on behalf of myself and
the said Johnson Hill and John Butler have hereunto set my hand and seal this
twenty third day of December in the year of our Lord one thousand eight hundred
and eighty three.
