ABSTRACT:
A fail-safe measuring weight comprises a body portion having a threaded bore therethrough, the threaded bore including a portion of reduced diameter. An adjustment plug for adjusting the weight to within a very fine tolerance of its final desired value includes a head portion and an exteriorly threaded stem portion, the stem portion being receivable in the reduced diameter portion of the body portion bore for securing the adjustment plug therein, and inhibiting inaccuracies of the weight due to improper use. Because the adjustment plug comprises 1% to 5% of the total weight of the instrument its absence may be readily ascertained. The fail-safe weight further comprises a cover member having a threaded bore for receiving adjustment particles which may be sealed therein. The cover member further includes a rod member, integral therewith and partially disposed therein transverse to the longitudinal axis of said cover member, portions of the rod member projecting from the sides of the cover member to form hand grips, whereby movement of the weight is facilitated.
