ABSTRACT:
A bar stock feed mechanism includes a filler tube having provision for coaxial alignment with an attachment to the rotatable work receiver of a lathe, for example, and is adapted to coaxially receive a section of bar stock for incremental feeding to the chuck of the lathe. The tube, at its end portion axially remote from the chuck contains a piston adapted to abut the proximate end of the bar stock, and the piston is pressurized for advancing the stock. Filler tubes are provided in several diameters for accommodating several sizes of bar stock. In the event of bar stock of substantial length, the filler tube is surrounded by a concentric extension tube which rotates with the tube and chuck or equivalent work receiver of the machine or lathe.
