The Lathe Headstock is the well known Hendey Tie Bar Pattern

Spindle is made from high carbon hammered steel forging, furnished under scleroscope hardness specifications, to insure ample rigidity and minimum wear in bearings after years of service.

Spindle Journals are both taper. The rear journal is in the form of a splined sleeve which permits independent adjustment in bearings. This allows for ordinary contraction or expansion of spindle without disturbing the running adjustment.

Bearings are Annular (one piece), and are automatically oiled with ring oilers from large reservoirs in housings. A constant stream of oil is supplied to bearings while spindle is running, and ample provision is made for collecting and returning the oil drip to reservoirs.

Keved to but sliding on the spindle is a long sleeve, Fig. 6. On this sleeve revolves the cone driving pulley. Oil is fed to the pulley bearings through oil hole in flange of sleeve. (See Fig. 7.) The pulley engages with face gear through locking pin in the usual way and so imparts direct drive to the spindle. The head has also the customary back gear.

End Thrust. All end thrust is taken on face of front bearing through a hardened and ground steel collar interposed between face of bearing and spindle collar. This thrust collar is carefully sized so that spindle will not wedge in its taper bearing under heavy end thrust, neither will it shake when running free.

End Adjustment of Spindle is obtained by means of collar and check nuts (S-1, S-2) indicated on spindle in front of rear bearing. The nuts push forward the long sleeve feathered to the spindle and abutting against the hub of the face gear which

is in turn pushed against the front bearing thereby drawing the spindle into the bearing.

To Remove the Spindle from Headstock, take off collar of front bearing (A), the guard over end of spindle, the collar (11), then by turning back the collars (S-1, S-2), and at the same time driving the spindle forward with a soft hammer, it may be removed.

If Necessary to Remove a Bearing. After taking out the spindle and the sleeve forming the rear journal, the oiling ring must then be raised up in its slot. Then the bearing may be driven out by using a block of wood which should be nearly the diameter of the bearing.
