ABSTRACT:
Rotation and linear movement of a main gear is provided by a pinion gear rotatably mounted on a crank arm and in meshing engagement with the main gear. A connecting arm between the gear centers keeps the gears in meshing engagement. The pinion gear may have a diameter one half the diameter of the main gear to provide rotation of the main gear 180 degrees after one revolution of the pinion gear. The crank arm may be rotated in opposite directions to provide oscillating movement of the main gear. In a tire building machine, the main gear may be mounted in a linear guide of an upright plate member for vertical movement. The main gear is connected to a shaft for rotating and tilting a hub member having two spaced apart tire building drums mounted with axes at an angle of 90 degrees and in the same plane as the axes of the tire building drums so that they can be oscillated between two fabricating positions.
