Apparatus for adjusting the relative inclination of two members

Claim 1

In an apparatus including a turret head having a spindle, said spindle having grasping means, said turret head being mounted for movement about a plurality of axes, a work table located in spaced vertical relationship with said spindle on said turret head, said apparatus having means for precisely adjusting the relative inclination between said spindle and turret head and said work table, the improvement comprising a first level indicating means including a platform having an upper surface and a lower surface a plurality of arms extending from said upper surface and converging substantially above the center of said platform, said arms being connected to a shaft, said shaft extending substantially perpendicularly with respect to said platform, said shaft being adapted to be grasped by said grasping means on said spindle, said platform including a bulls-eye level carried thereon so that when said shaft is grasped by said grasping means on said spindle, the inclination of said turret head and said worktable with respect to a reference plane will be indicated, a second level indicating means including a platform having a plurality of support legs extending therefrom, said support legs having contact ends all of which are adjustable to lie in the same plane, said platform of said second indicating means having a bullseye level located at its center so that, when said second indicating means is placed on said work table, the relative inclination between said turret head and said spindle may be determined by comparing the indications of said first and second level indicating means.
