Abstract

1377073 Shell moulding machine BIRMING- HAM SMALL ARMS CO Ltd 20 Aug 1972 [23 June 1971] 29388/71 Heading B3F A shell-moulding machine comprises a rotatable dump-box 1 having hinged thereto a pattern-carrying frame 4, the frame 4 being rotatable to and from a position in which it closes the dump-box 1 (as shown), by a rotary drive (not shown), that turns a disc 12. When the dump-box 1 is upright the frame 4 is coupled to the rotary drive by a clutch. The clutch comprises a disc 11 and the disc 12 which has an arcuate slot 14 for coupling with an arcuate projection 13 of the disc 11 which is fixed to a hinge spindle 5 and an arm 8 of the frame 4. Thus upon rotation of the frame 4 to a position remote from the dump-box 1, a completed mould can be removed from the frame 4 and the pattern (15, not shown), thereon can be preheated. After the frame 4 has been closed upon the dump-box 1 by the rotary drive, the dump-box 1 inverts with the arcuate projection 13 disengaging from the arcuate slot 14 so that the frame 4 remains closed on the dumpbox 1 while the pattern (15) is covered with shell-moulding mix.
