Patent Images
1. A feeler device for forming a measurement value when sensing a workpiece, said feeler device comprising:
- a housing;
means at one end of said housing for securing said housing to an actuating mechanism;
a measuring element mounted inside said housing;
annular mounting means fixed adjacent the opposite end of said housing for supporting a ball element within said housing for swivelling movement relatively thereto;
a carrying member axially fixed to said ball element;
at least one feeler pin fixed to said carrying member and projecting outside said housing;
means for yieldingly pressing said ball element against said mounting means;
means for activating said measuring element according to movement of said ball element from a neutral position thereof;
a guide element fixed to and extending along said housing in the vicinity of said ball element; and
a securing element extending out of said ball element to engage said guide element to prevent said feeler pin from turning said ball element at least in said neutral position thereof, said securing element comprising a cylindrical pin whose axis extends at a right angle to an axis of said carrying member through a center point of said ball element.

Abstract
The feeler device has a housing in which a deflectable member is mounted by means of a ball element which can be pressed against a mounting means under a spring bias. A securing element is arranged either fixedly or displaceably in the ball element, the securing element engaging into a guide element at least in the neutral starting position. The guide element preferably comprises two parallel pins.
