Abstract
A reference stop for use in a lathe having a movable chuck and a draw tube adjacent to the chuck. A movable backstop is provided for rectilinear movement within a sleeve. The sleeve is inserted through the chuck of the lathe and extends into the draw tube. A threaded rod is attached to the backstop and extends outwardly from the sleeve, into the draw tube, and in a direction away from the chuck. The threaded rod is turned by a wrench and driver combination, and turning of the threaded rod causes corresponding rectilinear movement of the backstop in the sleeve, thereby allowing for a workpiece reference stop which is adjustable with respect to the chuck.
Claims10
A reference stop for use in locating work stock in a lathe having a movable chuck, the reference stop comprising:
- a sleeve defining a longitudinal passage, said sleeve having a first end and a second end opposite said first end, and said first end of said sleeve being adapted for attachment to the chuck for movement therewith;
- a backstop carried for movement in said longitudinal passage;
- a threaded rod connected to said backstop and threadingly connected to said sleeve for rotation relative to said sleeve, such that rotation of said threaded rod moves said backstop substantially rectilinearly with respect to said first end of said sleeve;
- a threaded jam nut threadingly engaged with and rectilinearly movable with respect to said threaded rod carried adjacent to said second end of said sleeve for selectively fixing rotation of said threaded rod with respect to said sleeve;
- and
- said threaded rod having a first end and a second end opposite said first and, said first end being connected to said backstop, and said second end being a free end extending outwardly through said second end of said sleeve, such that said backstop may be selectively adjusted while in the lathe by rotating said second end of said threaded rod, and fixed against movement by said threaded jam nut.
