Abstract
345,533. Making clocks. SCHWAAR, R., 66, Quai du Bas, Bienne, Switzerland. April 22, 1930, No. 12374. [Classes 83 (ii) and 83 (iii).] Lathes; cutters.- Apparatus for finishing the converging edges of the notch of the pallet fork 5 comprises a cylindrical cutter 6 which is moved along the notch edges to give the latter a curved cross section. The pallet is fixed by an adjustable clamp 4 to a baseplate 3 and the tool 6, having a serrated cutting edge, is mounted on the end of a spindle 9 carrying a driving pulley 10 and mounted in bearings 7, 8. This spindle is retracted, until pulley 10 meets bearing 8, by a spring 13 and terminates in a handle 12 with lugs 11. The plate 14 carrying the spindle 9 &c. is pivoted on a baseplate 15 which has adjustable stops 16, 17. The handle 12 is swung against the two stops in succession, to position tool 6 correctly for cutting the two edges of the notch, before this tool is moved forward to the pallet.
