ABSTRACT:
A tail stock ram drive mechanism comprising a removable end adapter member adapted to be attached to the rear end of a tail stock guide about the axis of the guide, a housing member and means for removably attaching the housing member to the adapter member. The housing and adapter members each have a bore axially aligned with each other and with the guide. The bore of the housing and adapter members slidingly accomodate a gear rack. The housing is provided with a through bore extending transversely of the housing bore which accomodates the gear rack. A pinion shaft having a pinion mounted thereon is rotatably mounted in the transverse bore with the pinion meshing with the gear rack. A hub and lever assembly are mounted on the pinion shaft for operating the pinion shaft and thereby the gear rack. Means are provided for selectively limiting the forward and backward movement of the gear rack and for holding it in a given position when performing centering work, for example. The housing member is angularly adjustable about the axis of the adapter member and carries means for locking the housing member in a desired angular position with respect to the adapter member. In a preferred embodiment, removable connector means are provided for connecting the forward end of the gear rack with tail stock rams of various sizes.
