ABSTRACT:
Method of making at least two different electrical interconnections with at least two wires extending from windings supported on a dynamoelectric machine core. The method includes moving the core, windings, and at least two wires toward a wire connecting device; orienting and positioning a first one of the at least two wires relative to the device; and thereby conditioning the device to establish a first one of at least two different connection configurations. A first electrical interconnection involving a first wire and having a first connection configuration is formed. A second winding lead then is oriented and positioned relative to the device, thereby to condition the device to form an interconnection having a second connection configuration, and such interconnection is made. Indicia that indicate the relative orientation of the stator assembly (or parts thereof) are utilized to condition the device to establish connections of desired different configurations. A stator holder is operatively interconnected with indicia means which may be limit switch actuating cams. Movement of the stator holder causes corresponding movement of the cams. The cams in turn establish the condition of control means that are operative to condition the apparatus so that crimped interconnections of predetermined final configurations are established. Another method involves adjusting the operational mode of a prime mover that controls the effective stroke of crimping tooling. The difference between minimum and maximum tooling movement is substantially continuously variable. In an illustrated form of apparatus, the prime mover is a pneumatic cylinder, and a rack is driven with the rod of the cylinder. The rack meshes with and rotates a drive pinion that is rotationally locked with eccentric means which support a toggle linkage. A method of scrap removal is provided which includes the steps of exhausting a pneumatic cylinder; guiding the exhausted air to a venturi chamber and thereby establishing a vacuum adjacent a crimping station thereby to collect scrap material; and directing the scrap material, along with the exhausted air, away from the crimping station.
