Abstract
As turret 12 rotates on vertical axle 20, probe assemblies 14 are raised and lowered by cam track 29. Drive belt 76 engages the drive sheave 42 of the probes as the probes pass around the back of the machine, causing the probes to rotate about their longitudinal axes 46. Ring cam 48 urges cam sheaves 58 radially outwardly into engagement with the belt 76 to disengage the belt from the probe drive sheaves 42, so that the probes 34 rotate only during part of their revolution about the turret 12. Probe head 35 includes a stem 88 of parallelopiped cross section, with helical teeth 90 and 91 which extend at a radius from the acute angle into overlying relationship with respect to the obtuse angle of the stem.
