ABSTRACT:
A guiding device for a traveling service unit for a spinning machine having guide rollers supporting the service unit on the floor and related to a rail engaging member to maintain the service unit at a predetermined spacing from a guide running along the machine. In one form of the invention, the guide rollers are pivotally mounted and are pivoted by a connecting rod of the rail engaging member to direct the guide rollers toward or away from the rail upon any deviation of the travel of the service unit so that the service unit will be guided at a proper spacing from the rail and, therefore, from the components of the spinning machine. The control rod can be maintained in proper relation to the rail by followers on the rod straddling the rail or by a spring mounted on the servicing unit and biasing a follower roller on the rod against the rail. As an alternative form, the guide rolls are skewed slightly from the longitudinal direction of the service unit to bias the service unit in the direction of the rail, maintaining a follower roller on the service unit in contact with the rail to properly position the service unit with respect to the spinning machine. The skewing can be fixed or can be spring biased. In the form of the invention where the guide rollers are movable, the control rod can be independently shifted laterally to pivot the guide rollers for selective steering of the service unit away from and independently of the rail.
