Abstract

654,019. Copying by turning. DEHN, S. G. (Vulcan Corporation). Oct. 15, 1948, No. 26895. [Class 83(iii)] A lathe for turning shoe lasts comprises a substantially vertical frame 26 carrying a model last 24 and workpieces 25, rotated from a reversible electric motor 72, and pivotally supported on a base frame 10 by means of spaced links 37, 38 so as to be reciprocable horizontally, an inclined table 55 carrying a copying disc 60 and work cutters 59 and movable vertically by means of feed screws 66 driven from the motor 72 in timed relationship with the rotation of the model last and workpieces, the frame 26 being urged towards the disc 60 and cutters 59 by means of springs 56, 57 encircling rods 43, 45 secured to the base frame. Pivoted on the rods 43, 45 are pairs of bell-crank levers 41, 42 which serve to maintain the frame 26 in a vertical position, the horizontal arms of each pair of bell-crank levers being connected by a link 47 and the vertical arms being connected to the frame 26 by means of links 48, 50. The frame 26 is moved to and from the operative position by means of a lever 52. The upper and lower limits of motion of the table 55 are determined by electric switches 82, 83 connected to the motor 72. The cutters 59 are rotated by electric motors 58. Two of the workpieces are rotated in one direction and the other two in the opposite direction. Reproducing to different scale.-The lathe is provided with a length grading device comprising a copying disc platform 89, Fig. 5, mounted on the table 55 for independent vertical movement and having downwardlyspaced grooved guide arms 90, which receive a guide member 92 having an inclined slot 93 to receive the table 55 to which the member 92 is fixed, the platform 89 and member 92 being connected differentially by means of a lever pivoted to the guide arms 90 and having a groove therein to receive slidably an adjustable block which is pivotally connected to a link which in turn is pivotally secured to the member 92. The outer end of the lever is adjustably connected to an arm which is secured to the base frame. The lathe is also provided with a width grading device comprising a block 96 horizontally slidable on the platform 89 and having slidably secured thereto a follower 107 which engages a follow board 108 pivotally connected to the base frame, the follow board having extending from the upper end thereof a width-grading lever which is adjustably pivoted to a link pivoted to the frame 26.
