Abstract

1,063,266. Machine tool details. BROWN & WARD (TOOLS) Ltd. June 22, 1964 [March 23, 1963], No. 11608/63. Headings B3B and B3T. A bar stock feed comprises a bar guide, formed in members (10) (12), a feed device (15), and a steady (41) coaxial with the guide, the steady having jaws (46) biased towards the bar (61). Members (10) and (12) have semicircular grooves 11, 13 therein to form the bar guide, and feed device (15) comprises a rod (17) movable in the guide by a member which passes through a gap (16) between members (10) and (12). Sprockets (24) reciprocate device (15) through a chain (23) having a pin (25) located in a slot (26) in the device, and limit switches (27) and (27a) are provided to cause a slow approach feed and a fast retraction. Device (15) has an abutment (29) which coacts with ears (30), (31) on a lever (32) pivoted to a rod (33), the latter also being pivoted to arms (34) which in turn are pivoted to levers. Arms (34) are connected to members (12) so that an abutment (29) coacts with ear (30), rod (33) moves to withdraw the means and allow a bar (19) to drop into groove (11). Simultaneously the cam levers move holding means (35) to prevent the remaining bars (19) from dropping. A rotary tube (37) is arranged coaxial with the bar guide and is supported in a bracket (38), so that its end (39) is spaced from the lathe spindle (40) a steady (41) is secured to the tube and comprises a sleeve (43), secured to the tube at (44) and jaws (46) guided in slots in a flange (45) provided on the sleeve. Each jaw has a semicircular rib (47) which is held in a similar groove (48) in the sleeve by screws (61), and the jaws are biased towards the bar by a helical spring ring (49), and springs (56). A number of steadies may be positioned along the bar guide.
