Abstract:
A lock washer comprising:a pair of components in coaxial relationship along a common axis and having opposing inner surfaces with each of said surfaces provided with a plurality of inclined smooth surfaced ramps; each of said ramps terminating at a raised linear edge end with a downwardly extending vertical locking face; said components raised linear edge ends ride in sliding relationship upon respective ones of said inclined smooth surfaced ramps of said opposing component surface ramps until said locking faces of adjacent ramps of said components engage; a plurality of rounded, non-pointed, elongated raised ridges on an exterior or outer surface of each of said components opposite to said inner surface provided with said ramps; a central opening in each of said components coaxially disposed with respect to each other for insertably receiving a threaded shank of a fastener; said components having a circular edge-marginal region coaxial with and in spaced-apart relation with said central opening and said circular edge-marginal region defined by a peripheral edge; said raised ridges disposed in fixed spaced-apart relationship and that extend radially outwardly from said central opening at an angle with respect to each other, said elongated ridges having vertically extending end faces located respectively inwardly from said peripheral edge and outwardly from said opening; and said components are circular in configuration having the same diameter and with a continuous and uninterrupted smooth peripheral face wherein said smooth peripheral face of each component is coextensive with said smooth peripheral face of the other component of said pair of components and wherein said pair of components are non-operative for effecting engagement or disengagement with respect to each other.
