Abstract

A drive mechanism for automatic paint stirring equipment of the type having a housing and a plurality of spaced apart and parallel shafts rotatably mounted to the housing. Each shaft is adapted for detachable driving connection with a stirring assembly associated with a lid on a paint can supported on the housing. The drive mechanism includes a gear wheel secured to an upper end of each of the shafts and an elongated rigid gear rack which meshingly engages a plurality of the gear wheels on the shafts. The gear rack is reciprocally longitudinally driven through a wheel and link assembly to simultaneously reciprocally drive the shafts in alternating rotational directions. This alternating rotational movement is, in turn, transferred to the stirring assembly associated with the paint can for each of the drive shafts.

Claims6

Dependent claims

For use in conjunction with automatic paint stirring equipment of the type having a housing with a plurality of spaced apart and parallel shafts rotatably mounted to the housing, each shaft adapted for detachable driving connection with a stirring assembly associated with a paint can, a drive mechanism for reciprocally simultaneously driving a plurality of said shafts comprising:

a driven member secured to each of said shafts,
an elongated rigid drive member, said drive member having means for drivingly engaging a plurality of said driven members so that longitudinal movement of said drive member simultaneously rotatably drives said driven members,
means for longitudinally reciprocally driving said drive member
wherein said longitudinal reciprocal driving means comprises:
a motor which drives an output shaft,
an elongated link,
means for pivotally connecting one end of said link to one end of said drive member, and
means for pivotally connecting the other end of said link to said output shaft at a position radially spaced from an axis of rotation of said output shaft.
