DEFINITION

Classification: 81/412

(under subclass 411) Tools in which the pintle has a cross-sectioned bearing portion with both a maximum and a minimum dimension, the slot has a plurality of longitudinally spaced enlarged portions substantially equal in size to said maximum cross-sectional dimension, and the enlarged portions are joined to each other by slot portions substantially equal in size to said minimum cross-sectional dimension.

(1) Note. Adjustment is effected by pivotal shift of the pintle so as to align the minimum pintle portion with the minimum slot portion and translational shift into the desired maximum slot portion.

(2) Note. It is not necessary for the enlarged portions of the slot to extend entirely through the handle.
