ALBERT EDWARD COTTOM, OF EAST BRUNSXVICK, NEAR MELBOURNE, VICTORIA, AUSTRALIA.
. MEANS FOR MANUFACTURING GASTINGS FOR SHAPING AND DRYING HOSIERY.
Application filed April as,
To all whom it may concern:
Be it known that ALBERT EDWARD Corrora, a citizen of the Commonwealth of Australia, and resident of 21 Lydia Street, East Brunswick, near Melbourne, in the State of Victoria, Commonwealth of, Australia, has invented a certain new and useful Means for Manufacturing Castings for Shaping and Dryin Hosiery, of which the following is a speci cation.
This invention relates to an improved means for manufacturing castings for shaping and drying stockings, socks and the like and has been specially devised in order to overcome the defects in the method and castings at present employed.
In the method and means at present em ployed, no means have been provided to counteract the effect and pressure of the steam as it is blown through the steam passage of the casting during the shaping and drying of the articles and in practice it has been found that even with only a thirty pound head of steam, the latter forces through eruptions of the casting and blowing therethrough causes blisters on the articles being shaped or dried with a consequential loss of material as well as rendering the casting valueless until the holes are plugged.
The invention has been devised in order to obviate existing defects in the drying and shaping of articles and to provide means whereby such defects are overcome in a cheap, simple and effective manner and whereby the cost of upkeep, material and labour is reduced to an absolute minimum.
The salient feature embodied in this invention consists in the formation of a steam passage or lining in the casting which will withstand a maximum pressure of steam and which will prevent the contact of the steam with the outer material forming the body of the casting by means of a metal tube so fashioned and disposed within the casting that the steam circulates through the tube, so heating the casting in an even and efiective manner.
A further essential feature embodied in the invention consists in the method of shaping the steam tube or pipe; and in the method of mounting the. same in the mould so as to prevent blowing blistering and any eruption in the casting.
A further essential feature consists in the Specification of Letters Patent.

combination with a casting of metal or other suitable material for the purpose specified of a metal pipe or tube with a steam inlet and a steam outlet, the pipe being so disposed as to effectively impart the heat to the casting or body for drying and shaping the articles carried thereby.
In order that the invention may be more readily understood it will now be described with reference to the accompanying drawings in which Figure 1 is a View in plan of the improved steam pipe or tube mounted in position on one half of a mould preparatory to casting the mould shape.
Figure 2 is a View in plan of a die plate and the pipe or tube bent to shape.
Figures 3 and 4c are side and plan views respectively illustrating the finished casting with the steam pipe indicated by dotted lines.
Figure 5 is a view illustrating an essential detail.
According to this invention, core boxes are dispensed with and a metal tube or pipe 64 of suitable length is annealed to soften and after annealing the tube is filled with sand, wax or other filling and the ends are plugged to prevent creasing or bending when shaping. The pipe or tube a is then bent to the shape indicated in Figure 2 on a die plate 7).
The filling and plugs are then taken out and the pipe at is flattened more or less to suit the thickness of metal in the casting.
Preparatory to fitting into the bottom half of the mould c the tube a is again filled with sand 7' to allow of the heating of the tube a by a heater, the heat imparted being such that it is retained during the casting operation to prevent blowing, blistering or any eruption that mi ht otherwise take place in the casting if the tube a remained cold.
The shaped tube a is then inserted in position in the mould portion 0 which is filled 'with sand and has one half of the pattern to be cast formed therein as at d.
The pipe a rests upon chaplets c buried in the sand in the bottom half of the mould c and also in the top half to prevent the pipe at from rising and falling under the action of the molten metal. Suitable means i are provided in the mould near the top thereof to efiect a pathway transverse to the ends of the pipe. A suitable gate or kit f is provided in the mould to allow of the ingress of the molten metal.
Afterrnoulding the casting g to the shape required, according to the pattern employed as atml the casting after cooling is dressed body g may not-beof metal but may be of other suitable material which may be of earthenware, fire clay or the like, moulded, cast or impressed to the shape required and having the pipe a mounted therein.
What I claim as my invention anddesire to secure by Letters Patent is- A mould for the purposes specified hav ing a steam passage formed by shapedpiping therein; means at: the top of the mould providing a pathway transverse to the ends of the pipe, the ends of the: pipebeing' also at the top of the mould and leading into the pathway substantially as described Signed: at Melbourne, victoriagrvAustralia, this 24th day ofMarch,192l.
