Abstract: A device for controlling in sequence or at the same time the feed of metal bars into a suitable guide equipment for supplying the bars to an automatic multi-spindle lathe is described.In order to connect the main control or drive to the bar feeding apparatus, the device includes a clutch, the coupling and decoupling of the clutch being caused by the rotation of the guide equipment. The portion of the clutch which is connected to the drive can rock around the axis of its support on the fixed frame during the coupling operation, and a return spring is provided to return rockable portion back to its starting position ready for the next coupling operation.

Abstract: A device is described which is meant to control the opening and closing of the metal bar sliding guides in a multiple-spindle lathe feeding equipment.Each sliding guide consists of two parts, a fixed one and a mobile one, and the device to open and close them is mainly made up of a locking pin integral with the fixed guide part, the releasing of which allows a mobile element to control the turning of a shaft with which the mobile guide part is integral.
