Image Description:
Hendey Lathes. — Lathes built by the Hendey Machine Company embody several characteristic and interesting features, which will be described in some detail. It is claimed that these lathes were the first to have a commercially successful equipment of mounted quick-change gearing, the details of which are covered by the Norton patents; but the lathes embody other important features, several of which are well illustrated in the general view of the belt-driven machine (fig. 14). This particular illustration shows the design in which the spindle is driven by means of a cone pulley through back gearing in the ordinary manner; but the same type of lathe is also fitted with an all - geared head, in which case the variations of speed are obtained entirely by means of gearing, and not partially by shifting the belt from one step of the cone to another.

The Bed. — A general end view of the geared -head type of machine is shown in fig. 15; and from this illustration it will be seen that the guiding surfaces of the bed are of the typical American inverted V form, and not of the English flat-surface type adopted in the two examples previously described. For the guidance of the saddle there are provided two inverted V guides, one at the front of the bed and the other at the extreme back. Between the outer V guides there are provided an inverted V and a plane surface for the guidance of the tailstock. This arrangement of separate guides permits of a long saddle being used without curtailing the travel, since the extended portions of the saddle can pass on either side of the tailstock and also of the fast headstock, and the cutting tool can operate on the whole length of the work between the centres.

From the illustration it will be seen that the bed is of ample proportions, and the rigidity is sufficient for the heaviest work the lathe may have to do. The bed is supported at either end upon simple feet and not upon cabinet legs, but in the case of the heavier machines the supporting area of the legs is extended, and an additional small support is placed under the middle of the bed to overcome any sagging tendency.
