ABSTRACT:
A cable guide comprises a support defining a pair of intersecting pivot axes which are inclined to the horizontal. A pair of wheels are each rotatable on the support about a respective one of the axes and each has an inside face turned toward the inside face of the other wheel and formed by an outer frustoconical region and an inner planar region. These inside faces approach each other most closely at a location above the intersection of the axes and the frustoconical outer regions are parallel to this location. An elastomeric disk is secured to the inner region of each inside face by means of a plate and is of a thickness such that the two elastomeric disks are pressed tightly together at the location at the top of the guide so as to form a groove adapted to receive and guide a cable.
