ABSTRACT:
A linear motion device particularly usable for providing a lateral movement stroke with vertical lifting and dropping performed at the extreme limits of movement of the lateral stroke which includes a base, two vertical shafts fixedly secured to the base and extending upwardly therefrom, a yoke movably secured to the vertical shafts to be vertically movable with respect thereto. The yoke member including a yoke pin extending outwardly therefrom into a lift cam which is circular and rotatably driven by being fixedly secured to a drive shaft, the lift cam achieving selective vertical movement of the yoke member responsive to the profile of the cam therein. The device further including a crank being reciprocally movable and secured to the drive shaft wherein the crank includes a pin at the outward section thereof which is radially movable toward and away from the axis of the drive shaft, the pin selectively rotatable within the channel of a plate cam at one end and in the channel of a vertical orientation device at the other end, the vertical orientation device secured to horizontally extending members which themselves provide the X and Y stroke of the movement, lateral movement achieved by the movement of the crank pin within the plate cam channel and vertical movement of the horizontal members achieved by the rotation of the plate cam with the yoke pin extending into the channel thereof.
