HENDEY MOTOR-DRIVEN LATHE
In the 1922 model 14-inch lathe of the Hendey Machine Co., Torrington, Conn., the motor has been placed beneath the oil-pan and the drive is through a speed-box in the left-hand pedestal and thence through a belt to the headstock spindle. By means of this driving arrangement, the lathe retains all the desirable features of the cone type and secures most of the advantages of the geared-head type. Eighteen spindle speeds are obtainable, nine through the speed-box in the pedestal and nine through the customary back-gears in the headstock. Reducing gears are located in the drive between the motor and the speed-box. The latter is oil-tight.
All driving parts of the lathe are enclosed, with the exception of the lead-screw and the faceplate, so as to protect the operator and the machine from injury. The interior of the headstock and speed- and quick-change gear-boxes may be conveniently exposed by the removal of a manhole or cover-plate. The headstock is equipped with a taper spindle and bearings, and is provided with means for taking up end play of the spindle. The single pulley and pinion run on a sleeve readily supplied with oil. An intermediate sliding feed-gear is operated through a conveniently located lever. The back-gear quill may be oiled while in motion. The carriage and compound rest are of improved design, and the tailstock has a graduated sleeve and effective clamping means.
The motor is controlled by push-buttons. An interlocking mechanism between the shifting levers and the starting panel enables the speed of an alternating or direct-current motor to be reduced automatically while gears are being shifted. Supplementary control of the spindle is obtained through a treadle running the full length of the bed. Pressure on this treadle instantly causes the spindle to stop rotating, and permits quick examination or calipering of work. The tension on the driving belt may be altered by means of a single-screw adjustment. |
