DEFINITION

Classification: 72/459

With work-complementing tool face adjacent to work-gripping clamp:

(under subclass 458) Implement provided with a work-engaging deforming surface closely proximate the work-holding means,

which surface, as disclosed, conforms to at least a part of the work.

(1) Note. The device disclosed in this and the preceding subclass is sometimes known in the plumbing trade as a "pipe hickey". In use, a hook on the device is applied to the work and force is applied to the lever in a direction tending to partially wrap the work around the tool-face defined, which tool face then mates with the inner curve of the work deformed thereby.
