Definitions

  • the present invention relates to copying lathes for manufacturing articles of various kinds such as for instance shoe-lasts, gun-stocks, pipe bowls and other irregular bodies of suitable material (for instance wood, metal, horn etc.)
  • Such lathes are used for copying models or a model of smaller or larger size than the copy which it is desired to produce.
  • Copying lathes for the manufacture of shoelasts are known in which movably mounted models and work pieces are pressed by springs against the tools (copying disc or copying roller or cutter heads). Usually copying discs and cutter heads of about 300 mm. diameter are employed. The work produced by such devices lacks neatness and precision, because the weight of the vibrating masses or" the model and work pieces is too great. Furthermore copying discs of such large diameters cannot penetrate into the lateral cavities of the last model. In consequence, no corresponding cavities being formed in the work pieces, they had to be made by hand subsequently.
  • a copying lathe provided with a copying roller or copying disc and cutter heads may be swung around different axes and in which the diameter of the cutter heads is such that any cavity may be produced.
  • the driving motors of the cutter heads are stationary on the axis of oscillation.
  • Copying disc and cutter heads are mounted one behind the other on a parallelogram of links it SHGE-LASTS AND Linn .lller, Germany 932, Serial No. 597,682,
  • FIG. 1 and 2 are side and end elevations, respectively.
  • a is the model of a shoe-last.
  • b are work pieces, the lasts for the left and the right foot being made simultaneously in the known manner.
  • 0 is the copying disc and d are the cutter heads having the same diameter as the copying disc. This diameter is such that a cavity of any size may be worked with these cutters.
  • the model a and the work pieces b are each fixed in the known manner between spindle e and sliding puppet f, the bearings g or" which are 7 mounted on the slide h. The latter is advanced in the known manner by spindle z in the direction of the arrow (Fig. 2).
  • the copying disc 0 is rotatably supported by an arm 7c and the cutter heads are rotatably supported by arms Z.
  • the .9 arms is and Z swing round the axles m, which are resting in the same plane on the base of the lathe.
  • the arms 70 and Z are joined together by the arms 12 to form a parallelogram of links which is operated by a spring 0.
  • the latter pulls the 5 tools (copying disc c) and cutter heads at towards the model a and the work pieces b respectively;
  • p is a handle fastened to arm 76 and having a notch q.
  • the tools may be drawn away from the work pieces and the parallelogram 99 of links Zcl-n may be fixed by placing the notch (1 on the saddle r.
  • s are the electromotors for driving the cutter heads. These motors are mounted on the base of the lathe independent from the rocking axles m of the arms Z. How- 9 ever (see Fig. 1) the axes of the motors coincide with the axes of the rocking axles m of the arms Z.
  • t are belts for transmitting the power and motion of the motors to the cutter heads.
  • the driving of the spindles of the lathe is effected in the known .19 manner by a main drive not represented (which also drives the feed spindle i) by means of the gearing I, II, III, IV shown in dotted lines in Fig. 1.
  • the copying disc 0 is pulled by 1 9 spring 0 towards the rotating and continuously advancing model a.
  • the work pieces I) are similarly rotated by means of the gearing I, II, III,
  • a copying lathe for shoe lasts, means for rotatably supporting a model and work pieces, a copying wheel and cutter heads of less than 300 mm. diameter, means for swingably mounting said wheel and cutter heads on separate parallel axles, a base for said lathe, means, including a plurality of shafts mounted near the base, for
