Abstract
An electromagnetic gripper assembly formed of a housing having an electromagnetic coil and armature reciprocally mounted thereon. A pair of gripper members are pivotally connected to the armature which is normally spring biased. The respective gripper members have a finger portion and a connected rocker lever portion, the latter having overlapping end portions by which they are pivotally connected to the armature to be actuated thereby as the electromagnetic coil is energized.
Claims7
An electromagnetic gripper assembly comprising:
- means defining a housing,
- an electromagnetic coil disposed within said housing,
- an armature extending within the field of said coil,
- a pair of gripping jaw members.
- means for pivotally connecting each of said jaw members to said housing means.
- and means for connecting the respective jaw members to said armature whereby the actuation of said armature by energizing said coil effects the pivoting of said jaw members between operative and inoperative positions.
- and spring means for normally biasing said armature and connected jaw members toward an inoperative position.

An electromagnetic gripper assembly comprising:
- a housing having a chamber formed in one end thereof,
- a bore disposed in alignment with said chamber and extending to the other end of said housing,
- said housing having a transversely extending groove disposed in communication with said bore.
- an electromagnetic coil disposed in said chamber.
- means for securing said coil in said chamber,
- an armature reciprocally mounted in said bore and said coil,
- said armature having a bifurcated end portion disposed within said groove,
- a pair of gripper members,
- each of said gripper members including a projecting finger portion and an angularly disposed rocker lever portion,
- said rocker lever portion of said gripper members being disposed in said groove,
- said respective rocker lever portions having their respective free ends disposed in overlapping relationship.
- a slot formed in the free ends of each of said rocker lever portions,
- said slot end being disposed in alignment.
- and said slotted free ends of said lever portions being reserved in the bifurcated end portion of said armature,
- a pin for connecting the respective free ends of said lever portions to said armature,
- a pivot pin for pivotally connecting each of said gripper members within said groove, whereby said finger portions of said gripper are pivoted between operative and inoperative position by the actuation of said armature, and
- a spring means for normally biasing said armature.
