  • Feed apparatus for automatic lathe
    Patent number: 3945506
    Abstract: A bar stock feeding apparatus for an automatic lathe, comprising a tube for guiding the bar stock. A piston is situated in the tube behind the bar stock for pushing it towards the headstock of the lathe, the piston itself being urged towards the headstock by means of oil pressure while part of the oil overtakes the piston by flowing through a clearance left between the piston and the inner wall of the tube and through an inner channel through the piston having an adjustable cross-section. Regulating means and non-return valve means are provided in the inner channel for rendering the piston retractable responsive to oil underpressure applied instead of the oil pressure.
