First Claim
Patent Images
1. In a microtome of the type having a first member pivotally movable with respect to a second member on a pair of main pivot balls captured between fixed sockets provided on one of the members and a fixed and a movable socket provided on the other of the members, the improvement which comprises:
- a misalignment pivot system for permitting movement without the generation of a restoring force of the movable socket in the direction of an axis (Q-Q'"'"') connecting the centerlines of the balls to match the exact separation between the main pivot balls,the misalignment pivot system itself comprising a socket and a groove formed on either the movable socket or on one of the members and a pair of fixed sockets confrontationally provided on the other of the movable socket or the one of the members, a first misalignment pivot ball captured between a pair of fixed sockets and a second misalignment pivot ball captured between the fixed socket and the groove, the axis (W-W'"'"') between the centers of the misalignment pivot balls being substantially perpendicular to the axis (Q-Q'"'"') connecting the centerlines of the main pivot balls.

Abstract
A misalignment pivot system for permitting pivotal movement of a main pivot socket in a direction along an axis Q-Q'"'"' connecting a pair of main pivot balls includes a pair of misalignment pivot balls one of which is captured between a fixed socket and a V-groove. The misalignment pivot system permits pivotal movement of the main pivot socket without the imposition of a restoring force.
