ABSTRACT:
Apparatus for feeding elongated bars into the work spindles of an automatic multiple-spindle bar machine has a turret which is mounted behind and is indexible with the carrier for work spindles, elongated tubular guides mounted in the turret and each registering with a work spindle, pushers reciprocably mounted in the guides and having projections extending laterally outwardly through longitudinally extending slots of the corresponding guides, and discrete drives for the pushers. Each drive is a chain drive mounted on the turret and having a chain a stretch of which extends in parallelism with the corresponding guide and is connected with the projection of the respective pusher. The rear sprocket wheels for the chains can be driven by discrete bevel gears through the medium of friction clutches, and these bevel gears are in mesh with a further bevel gear which is coaxial with the turret and is driven by a reversible motor by way of a worm drive and an endless belt or chain. The motor is automatically reversed when a projection actuates a limit switch which is mounted in the machine frame adjacent to the path of movement of the respective projection and is adjustable lengthwise of the respective guide.
