Vintage Machine:Bevel Wheel Shaping and Dividing Machine

Designed to shape the teeth under the guidance of a copy or former, four or five times the size of the desired tooth. The tool is held in a box carried by a reciprocating slide, like the slide of a shaping machine, and has a stroke of about 6 inches. The wheel or blank is mounted on a spindle, the nose of which is covered, and fitted with a steel mandrel to receive it. The spindle is carried on two bearings, of which the upper can be moved in a slide by a screw to adjust the wheel. The other bearing is a long socket, and is itself carried by a bearing on a segmental plate capable of rotation a about a point toward which the cutting edge of the tool always travels. The spindle can be moved endwise by the upper bearing to set the blank in the first instance, and can be rotated by a worm and wheel on the lower socket. Attached to this same socket is a curved radial lever, carrying at its extreme end the copy or former, which is kept in contact with a steel guide plate by means of a weight having a cord passing over guide pulleys.
