Abstract:
A feeder system for metal casting comprising a feeder sleeve mounted on a tubular body. The feeder sleeve has a first end and a second end and a longitudinal axis extending generally between said first and second ends. The feeder sleeve comprises a continuous sidewall that extends generally around the longitudinal axis that defines a cavity for receiving liquid metal during casting and the sidewall has a base at the first end of the feeder sleeve. The tubular body defines an open bore therethrough for connecting the cavity to the casting in use. The feeder sleeve comprises at least one cut-out that extends into the sidewall from the base to a first depth and the tubular body projects into the cut-out to a second depth, the tubular body having at least one abrading region in contact with a surface of the feeder sleeve within the cut-out. The second depth is equal to or less than the first depth so that upon application of a force in use the abrading region abrades the surface of the feeder sleeve with which it is in contact such that the tubular body is pushed towards the second end. The invention also resides in a feeder sleeve for use in the system and a process for preparing a casting mould employing the system.

Claim (Index 4):
The system of  claim 3 , wherein the groove is inwardly tapered towards the second end of the feeder sleeve.
