I, ROBERT PURDY TICKLE, of 57 Achilles Road, West Hampstead, Middlesex,
Traveller do hereby declare the nature of my said Invention to be as follows :-
The object of this Invention is to cast material, other than metal, in a casting
box in which the fluid or plastic material under operation can be inserted on or
from one side of a partition, and as the mould or matrix becomes charged, the air
from the mould escapes from the other side of the partition. The consequence is, a
casting free from air or blow holes, no venting being necessary as with the ordinary
method.
The moulding box may be of any shape, and any number of articles can be
simultaneously or successively cast, the fluid or plastic body being poured into a
channel or groove common to all the moulds or matrices.
I purpose making my casting box of metal and to make the moulds as shells so that
water can be made to flow in chambers around or alongside of the mould or moulds
for rapidly cooling the articles within, or the casting box may be dipped into water
for the purpose.
The mould or matrix may be plain or provided with devices so that the article when
cast has a reverse of the device, the moulds themselves being stamped up and secured
in the mould box.

1, ROBERT PURDY TICKLE, of 57 Achilles Road, West Hampstead, Traveller,
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:-
--
The object of this invention is to cast material, other than metal, in a casting box 5
in which the fluid or plastic material under operation can be inserted on or from
one side of a partition and as the mould or matrix becomes charged, the air from
the mould escapes from the other side of the partition, the consequence. is. a.
casting free-from air or blow holes,-no-venting-being-necessary as with the ordinary
method.
The moulding box may be of any shape and any number of articles can be
simultaneously, or successively cast the fluid or plastic body being poured into a
channel or groove common to all the moulds or matrices.
The mould or matrix may be plain or provided with devices, so that the article when.
cast lias a reverse of the device, the moulds themselves being stamped up and secured 1
in the mould box.
My invention will be understood by the annexed drawings :
Figure 1 is a side elevation of a long moulding box.
Figure 2 a plan of same.
Figure 3 a perspective elevation with part of the partition removed.
Figure 4 a section through lines a, a, Figure 2.
The moulds in the box shown are of globular formation but they may be of any
shape corresponding to the desired shape of the articles to be cast.
A, A, are two half boxes having half spherical chambers B, B, in them. These half.
boxes have sockets and pins C, C, as guides to "register" and end bolts D, D,
with-
fly nuts E, E, to lock the two half boxes closely in contact, the inner faces being
smooth to prevent the fluid material escaping.
:
Each "shape" in the moulding box has a neck G to enable the material to flow
into the "shapes" from the trough or hopper, H when poured in on one side of the
partition plate I, the lower edge of which only partially closes the necks, so that as the
material Bows in, the air escapes through the necks from the opposite side of the
partition and prevents the formation of blow holes and obviates faults in the cast
articles.
The shells in which the actual casting is effected, are of exceedingly thin metal, so
that they become rapidly cooled after the casting of the material and to expedite the
cooling, cold air, or cold water may be caused to impinge or flow against the outside
of the shells, or the moulds may be dipped into cold water for the purpose.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:―
1. The construction of moulding boxes substantially as shown on the annexed
drawings having a fixable partition for the escape of air during the pouring in of the
material other than metal from which articles have to be cast.
2. The employment of a partition in a casting mould or box when said partition
occupies a position for dividing the neck passage of the mould for the clear entry or
flow of the material into the moulds from one side and a simultaneously free escape
for air from the opposite side of the partition as and for the purpose described.
