Abstract: A crimper in which jaws are swung into crimping engagement with a bottle cap in response to downward movement of a plunger. Downward movement of the plunger is effected by a lever which is located below a handle joined to the body of the crimper. When the handle and the lever are squeezed, the lever is pulled upwardly toward the handle to actuate the crimper and, at the same time, the handle and the body are pressed downwardly to keep the crimper stable on the bottle. The length of the stroke of the lever may be changed by varying the setting of an adjusting screw which is carried by the lever.

Abstract: A hand-held tool for crimping a cap on a bottle includes a handle with a lever member pivotally connected to one end thereof to move a plunger between advanced and retracted positions within a housing depending from the handle. Within the housing are a plurality of die segments for gripping around the neck of the bottle to crimp the lower edge of the cap beneath the lip of the bottle when the plunger is moved into its advanced position. Telescoped on the upper end portion of the plunger is a coil spring whose upper end urges against an annular shoulder formed around the upper end portion of the plunger and whose lower end engages a circular disk and urges the disk downwardly on the plunger. An annular skirt depends from the disk and includes an inner, generally frustoconical wall surface mating with a similarly shaped outer surface formed on the upper end portions of the die segments.
