Abstract: 1,261,766. Drawing. WERKZEUGMASCHINENFABRIK OERLIKON-BUHRLE A.G. 11 July, 1969 [12 July, 1968], No. 35106/69. Heading B3Q. An apparatus for drawing and calibrating a cartridge case 16 comprises a necking die 1 movable in a bushing 2, a spindle 10 for calibrating the mouth of the case 16 and an ejector 8 movable relative to the spindle 10. The cartridge case 16 is pushed by a ram 17 into the die 1 which is moved against the action of springs 7 to abut a member 6 and which tapers the mouth of the case 16. When the ram 17 is withdrawn, the die 1 is moved by the springs 7 until the drawn mouth is applied against a gauging die portion 12 of the spindle 10. The ejector 8 is then moved to cause its head 9 to force the mouth of the case 16 over the die portion 12. The rearward movement of the die 1 is limited by a collar 3 of the bushing 2. During the further forward movement of the ejector 8, pawls 14 are forced radially outwards against spring force 18 by the ejector surface 15 to cause release of the spindle 10 which can then travel together with the ejector 8.
