ABSTRACT:
A bar puller for a machine tool, such as a lathe. The puller is provided with a body which mounts on the tool support so that the puller can be advanced radially toward the bar and also moved axially therealong to effect pulling. The body for the puller mounts a pair of rockers which project forwardly to effectively straddle the bar. These rockers mount rollers on the free ends thereof, the latter being provided with elastomeric surfaces to effect gripping of the bar. The body preferably has an adjustable guide pin which is moved to abut the side of the bar, thereby providing a three-point support. Springs urge the rockers inwardly toward one another so that the rollers grippingly engage the bar therebetween. When so engaged, the tool support is moved axially of the machine to effect the desired pulling of the bar.
