UNITED STATES PATENT OEErCE.
WILHELM VON PITTLER, OELEIPSIC, GERMANY.
SPECIFICATION' forming part of Letters Patent No. 485,773, dated November 8, 1892.
Application filed April 16, 1890. Serial No. 348,227. (No model.)
To all whom it may concern:
Be it known that I, WILHELM voN PITTLER, a subject of the German Emperor, residing at Gohlis, Leipsic, in the Kingdom of Saxony and German Empire, have invented certain new and useful Improvements in or Relating toTurning-Lathes and Similar Tools, of which the following' is a speciiication.
This invention relates to improvements in lathes adapted for turning, drilPling, mining, dac., and Which are adapted for small shops, locksmiths, grinders, tool-makers, Watch-makers, dre.
The object of my invention is to provide a machine of this kind in which the direction of motion can readily be reversed and the speed easily changed, as may be desired.
In the accompanying drawings, Figure l is an end view of my improved metal-working machine, showing the mechanism for changing motion and speed, parts being broken out and others being in section. Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is a longitudinal elevation of the entire machine, and Fig. 4 is an end View of the same.
Similar letters of reference indicate correspending parts.
A box-shaped casing D2 is mounted to turn on the end piece A3 of the bed-rail A2 and on the end of the screw-spindleQpassing through said end piece A3. In the casing D2 a vertical shaft a3 is arranged, which carries at its upper end a removable Worm-Wheel d4, adapted to engage a worm e3, formed on the end of the shaft L', which shaft is mounted in the bracket B2 of the head-stock frame B. A sleeve b5 is mounted to slide on the shaft a3, and is rotated from the saine by a spline c3. On one end of said sleeve b5 a bevel cog-wheel h3 is fixed and on the other end a cog-wheel b4 is fixed, both of which bevel cog-wheels b3 and b4 are adapted to en gage a bevelcog-Wheel g3, fixed on the end f3 of the screw-spindle C. A cam or concentric t is adapted to work in a circumferential groove formed in the sleeve h5, and said cam or concentric can be turned or actuated by a lever h', fixed to the stem of said cam or concentric t' and arranged outside of the casing D2. The direction of rotation of the spindle C can readily be reversed less diameter.
by shifting the lever 7L so as to disengage one of the bevel cog-Wheels b3 or b4 from the Wheel g3 on the spindle C and to engage the other bevel cog-wheel b3 or h4 with the bevel cogwheel g3 on the spindle at the same time. The speed of the screW- spindle can readily be changed by removing the Worm-wheel d4 and replacing it by a Worm-Wheel of greater or plished, as the entire easing D2, carrying the shaft a3, can be turned on the end part of the spindle and the end part of the bed-rail to have the requisite inclination according to the diameter of the Worm-Wheel, which inclination increases with the diameter of said Worm-Wheel.
Having thus described my invention, I claim as newr and desire to secure by Letters Patentl. In a metal-Working machine, the combination, with abcd-rail and a screw-spindle in the same, of a casing mounted to turn on the end of the bed-rail and on an extension of the spindle, a shaft in said casing, a sliding sleeve This can readily be accorn- 6o on said shaft, bevel cog-Wheels on the end of the sliding sleeve, a bevel cog-wheel on the end of the spindle, adapted to engage either of the bevel cog-Wheels on the sleeve, and a driving-Wheel on the upper end of the shaft in the casing, substantially as set forth.
2. in a metal-Working machine, the combination, with a bed-rail, of a screw-spindle in the same, a casing mounted to turn on the end of said bed-rail and on an extension of the spindle, a shaft in said casing, a sliding sleeve on said shaft., bevel cog-wheels on the ends of said sleeve, a bevel cog-Wheel Xed on one end of the spindle and adapted to e11- gage either one of the bevel cog-Wheels on the sleeve, an eccentric or cam arranged between collars on the sleeve, a lever on the stem of said eccentric or cam, and a driving-Wheel on the upper end of the shaft in said casing, substantially as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
WILHELM VON PITTLER.
