Cl. 164301 7 Claims ABSTRACT OF HIE DKSCLOSURE Mould support carriage for a centrifugal casting machine which employs two pouring troughs alternately, the carriage carrying on each side a longitudinally extending assembly of aligned channel-sectioned supports for receiving and supporting the corresponding trough while the other trough is being used for casting.
The present invention relates to machines for centrifugally casting iron pipes having a socket in accordance with the de Lavaud method, as described, for example, in US. Patent No. 1,329,295. The invention more particularly relates to the mould support carriage of machines of this type having a high output and equipped with parallel pouring troughs.
It is known that the pouring troughs or channels have great length and a small section and are subjected to high flexion due to their weight. For the purpose of avoiding an excessive sagging of the end of each trough, and in particular the end of the trough which is inoperative and at rest while the other trough is operative (since the end of the operative trough can rest on the inner wall of the centrifugal casting mould), the invention aims at providing very simple guide and support means.
The object of the invention is to provide a mould support carriage for a centrifugal casting machine wherein the liquid metal is supplied by way of one or the other of two parallel pouring troughs, said carriage carrying on each side, namely on the right and left side thereof, a longitudinally extending assembly of aligned supports f r receiving the corresponding right or left trough when inoperative and at rest, said support assemblies being spaced apart transversely of the carriage a distance equal to twice the distance between the two pouring troughs.
