A multiple orientation drive device (22) for use with a beverage brewing apparatus (20). The beverage brewing apparatus is a type having a brew chamber (24) which includes a top and bottom assembly (26, 28) and an elongated brewing component (36) extending into the brew chamber. The elongated brewing component is associated with the drive device such that it is linearly and rotatably shiftable in the brew chamber. The linear and rotatable shifting are independently achieved by the actions of an independent linear drive assembly 50 and an independent rotary drive assembly 52. The linear drive assembly is associated with the brewing component for linearly driving the brewing component in the brew chamber and the rotary drive assembly is associated with the brewing component for rotating the component independently of the linear drive assembly. The present invention also includes synchronizing the linear drive assembly and rotary drive assembly to simultaneously linearly shift and rotatably shift the brewing component in the brew chamber. A sensor assembly 48 is associated with the drive device to indicate the position of the brewing component in the brew chamber. The sensor assembly is coupled to a control device 94 which in turn is attached to the linear and rotary drive assemblies. The control device selectively energizes and deenergizes the linear and rotary drive assemblies in response to predetermined conditions defined by the control signal from the sensor assembly.
