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 achie…
