Abstract: A bar stock supporting and feeding apparatus which includes first and second series of bar stock support members centered about a longitudinal axis and movable with respect to the axis to rotatably engage a length of bar stock. An adjustable stop mechanism is provided to quickly adjust the apparatus to rotatably support bar stock of different diameter. A loading and unloading mechanism is provided which does not require that an operator's hands be placed dangerously close to the apparatus. A bar stock feeding apparatus is provided with a similar gear system for engaging the bar stock and feeding it into an adjacent machine tool. A fail-safe mechanism prevents disengagement of the support apparatus in the event of a loss of fluid pressure in the system.
