DEFINITION
Classification: 269/133
(under subclass 86) Device including at least two coacting jaws* and their supports with a work underlying portion(s) that (A) is attached to or integral with either a jaw(s) or a jaw supporting structure(s), and (B) is so interconnected with one or more jaws that the force of gravity on the workpiece, upon contact with the underlying portion(s),
actuates* the coacting jaws.
(1) Note. The most common panel or workpiece present, in the patent disclosures placed in this subclass, is a door or window supported during planing, weatherstripping, etc.

157+, for patents to a holder including claimed means to urge jaws away from the work.
217, for patents to a holder including means to resist further movement of the work once it is gripped. 218+, for patents to a holder including a single means to actuate coacting jaws.
237+, for patents to a holder with pivoted jaws.
