Abstract

267,033. Long, G. A. Oct. 16, 1926. Keys for locks.-A machine for cutting slots in key blanks or the like comprises a number of adjustable rotary cutters and a carrier for one or more blanks movable to bring the blank under the operation of each cutter in succession to cut a series of notches in the blank. The carrier 6, which carries two blanks clamped by means of a hand-lever 22, is mounted on a series of plates 7<1> carried by a reciprocating slide 4. The main driving-pulley 9, driven by a belt from an electric motor &c. drives through worm gearing 11 and spur gearing 14 - - 19, a shaft carrying a cam 20, which through links 21, 23, pinion 24, fixed rack 26 and an upper rack 27 secured to the blank side, reciprocates this slide to carry the blanks past a series of rotary cutters 28. The cutter-spindles are driven from the main shaft through belt gearing 44, spur gearing 39, worm gears 36 and universal shafts 31. In order to -adjust the cutters to cut notches of various depths in the blanks, the cutter-spindles are each mounted in bearings supported by a pair of connected wedge-members 46, 47. The wedges are operated by hand-levers 50 moving over quadrant plates 52, the positions of the levers being determined by spring detents 51. Each lever is pivoted at 49 to a bearing 48 and connected by pin and slot to a wedge 47. A clutch 61 operated from a handle 62 is incorporated in the driving-train of the blank-carrier.
