Lighter Levers and Arched Step.

This shows our pattern for arched bridge pot and lighter lever for geared mills or when an elevated step is wanted. The part holding the steel on which spindle rests, is contained in a central lifting chamber, which is turned to fit the body of the arch, like a piston, thus allowing a perfect perpendicular movement without any liability to vary from its true position; the heavy set-screw at the rear end of the lever is to admit of more adjustment; the lever can be moved around at most any required angle without interfering with any part of the step. We provide means (not shown in this cut) to tram the spindle by screws placed in the central lift part of the step, when desired.
