PROVISIONAL SPECIFICATION.
Improvements in the Method of Moulding Plain and Flanged
Cylinders, Cylindrical Pans, Pipes, and other Articles of similar
Form.
We, MATTHEW EDWARD GALLON of 35 Heaton Park Road in the City and
County of Newcastle-on-Tyne, Iron Moulder, and THOMAS MAXWELL of S Bloom-
field Terrace Gateshead-on-Tyne in the County of Durham, Mechanical Draughtsman
do hereby declare the nature of this invention to be as follows:-
Our invention has for its object the introduction of improvements in the method
of moulding Plain and Flanged Cylinders, Cylindrical Pans, Pipes and other
articles of similar form and is designed to facilitate the making of such articles.
This object is secured in our Invention by making the rings or binders which
are used in the construction of these moulds, in two or more segmental sections,
instead of in one complete ring as heretofore; these sections being connected and
bound together by clamps or other suitable fastenings in such a manner that the
mould, after each cast, can be stripped in sections, the walls of the said sections
remaining intact.
To re-construct the mould after each successive cast, the segmental sections are
again placed in position and bound together; the sweeping or refacing of the mould
being all that is required to restore it to its original condition.
The core we treat in a similar manner to the cope."
By our Invention the same mould can be repeatedly used and therefore the cost
of manufacture will be considerably reduced.

COMPLETE SPECIFICATION.
the Method of Moulding Plain and Flanged
Cylinders, Cylindrical Pans, Pipes, and other Articles of similar
Form.
We MATTHEW EDWARD GALLON of 35 Heaton Park Road in the City and
County of Newcastle-upon-Tyne, Iron Moulder, and THOMAS MAXWELL of 8 Bloom-
field Terrace, Gateshead in the County of Durham, Mechanical Draughtsman do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention has for its object the introduction of improvements in the method
of making and of moulding Plain and Flanged Cylinders, Cylindrical Pans, Pipes,
and other articles of similar form and is designed to facilitate the making of such
articles whereby the cost of manufacture is considerably reduced.
According to the method usually adopted in the moulding of cylindrical articles
the rings or binders used in the construction of the mould are made in complete
circles, and this form of construction necessitates the destruction of the mould before
the casting can be extricated.
Our improvement consists in making such rings or binders in two or more segments
instead of in one complete ring as heretofore, the spaces between the rings being
built up in brick and loam in the usual manner.
The sections when completed, are bound together with clamps or other suitable
fastenings in such a manner that the mould can be stripped in segments after

page_text: the cast has been made, each of the said segments remaining intact during this
operation.
In order to reconstruct the mould, the segments are again placed in position upon
the sole plate and bound together; the refacing of the mould being all that is then
required to restore it to its original condition and ready for another cast.
The core is treated in a similar manner to the cope, being composed of three or more
segments connected together by radial arms with adjustable connections, whereby the
free contraction of the casting is permitted to take place while the core itself is
perfectly free and may be easily withdrawn.
The manner in which we propose to apply our invention is shown upon the
accompanying drawing, in which Fig. 1 is a vertical section through the completed
mould Fig. 2 is a sectional plan and Fig. 3 an outside plan on the top of the mould-
In describing the operation of moulding by means of our improved mould, like letters
in the description refer to like letters upon the drawing.
The centre pin or spindle a having been removed, the connections b, b, b, eased,
and the cast made; the wedges c, c, c, which may be made of cast iron or other
suitable material, are then simultaneously withdrawn-The core sections d, d, d may
then be removed at pleasure-The cope fastenings may now be removed when the
various sections e, e, of which the mould consists may be seperated in their entirity.
To reconstruct the mould, the sections constituting the cope are again placed in
position upon the bottom ring f, fastened together, and re-faced or swept up in the
usual manner- -The completed cope being removed for drying; the core sections are
then placed in position upon the sole plate, the connections made secure, and the
surface refaced with loan-After being dried and blacked, the mould is put together
in its completed form, when the casting is made and stripped in the manner before
described.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
consider to be novel, and therefore claim to be our Invention is :-
The general arrangement and construction of moulds as hereinbefore described to
be used for the casting of Plain and Flanged Cylinders, Cylindrical Pans, Pipes, and
other articles of similar form whereby the same mould may be used repeatedly and
in this way affect a considerable reduction in the cost of manufacture as well as
a great saving in the time required for their production.
