Abstract

1298442 Making lasts W G KLINGBEIL 2 Jan 1970 [13 Aug 1969] 175/70 Heading A3B [Also in Division G3] A shoe-last is shaped from a blank by moving the blank with respect to a fixed cutter in response to electric control signals. As shown, a model 10 of a shoe-last, formed in paraffin wax, is mounted on a rod 11 driven through gearing 13 by a drive device 12. The shape of the shoe-last is sensed by a transducer 16 mounted on a lead-screw mechanism 17, 18 driven through gearing 19 from the drive device 12. The outputs of the transducer 16 and the mechanism 17 are fed to a sensing means 21 in which they are converted to a form suitable for permanent storage in a magnetic tape, drum or punched tape memory 22. The memory is read out by a device 23 into a converter 24 wherein they are changed into a form suitable to actuate an hydraulic transducer 26. The transducer 26 provides a mechanical output to a transmission device 27 which causes a probe 28 to be moved by an hydraulic control 30 against a polished steel bar which is movable to cause a driven blank 34 to move against fixed cutters, not shown, to form a replica in wood of the shoe-last model. The cutter 28 and control 30 are traversed by a device 31 along a rod 32. It is stated that the memory 22 can be arranged to simultaneously control a plurality of probes 28 to produce a plurality of shoe lasts.
