Abstract
In a turret mill of the kind in which a doughnut 20 moves with the tool head along a threaded vertical rod 1, a tube 4 is slidably mounted on the rod 1 between end plates 5 and 6 which support a turret 7. The turret 7 can be rotated to bring a series of axially adjustable stop elements 9 into position for contact with the doughnut 20, allowing downward movement of the tool head to be stopped in various quickly selectable positions. Such contact with a stop 9 causes the lower plate 6 to act on a head 3 secured to rod 1, which in turn operates a cutout 17 via a lever 16 to stop vertical feed of the tool head. Upward movement of the doughnut 20 engages the upper plate 5, which acts on the rod 1 via a plunger 25 and lever 26, causing the rod to move downwards. This again operates the cutout 17 to stop the tool head.
