Definitions

  • the present invention relates to mechanical or electronic focusing for initial adjustments according to technical instructions and relates to an adjustment screwdriver intended to allow this adjustment, cf. for example US-A-2 800 281.
  • the object of the invention is, for example, to note the adjustment of a screw very precisely before dismantling and to reposition said screw exactly during reassembly.
  • a tachometer adjustment screwdriver provided with a blade crimped in a handle, characterized in that on the tail of the blade is movably mounted a tubular part capable of moving in a recess in the handle receiving the tail of the blade, the handle being graduated on its periphery at the entrance to the recess and the moving part carrying a double graduation over at least part of its length, each graduation extending in opposite direction to each other.
  • a tachometer adjustment screwdriver produced in accordance with the invention comprises, in addition to the blade 1 and the handle 2, in which the shank 1 ′ of the blade 1 in 3 is crimped, a tubular piece 4 movably mounted on the blade 1 and inserted at least partially into the enlarged front part 5 'of the recess 5 provided in the handle 2 for the shank 1' of the blade 1.
  • the movable part 4 is internally threaded in order to be able to move on the tail also threaded 1 'of the blade 1 and it is provided longitudinally with a double graduation 6, 6', each graduation going in opposite direction with respect to the other.
  • the handle 2 For its part, the handle 2 carries on its periphery at the entrance to the recess 5 'a graduation 7 dividing said periphery into thirty two equal parts, the indications 1/4, 1/2, 3/4 appearing taking into account of the two possible directions of rotation.
  • Each 1/4 indication corresponds to a 3/4 indication and vice versa of different colors, the directions of rotation being represented by arrows 8, 8 ′ of corresponding color.
  • the blade 1 is provided with a sliding end stop 9 for the movable part 4 opposite the handle 2.
  • This stop 9 can be moved on the blade 1 having a flat, on which a locking screw is tightened of the stopper to maintain it at the chosen location.
  • the bottom of the enlarged part 5 ′ of the recess 5 serves as a limit stop for the moving part 4 in its movement opposite the blade 1.
  • a tachometer adjusting screwdriver is simple, quick and effective. During each operation requiring either the tightening or the loosening of an adjustment screw, it is important to unscrew and screw the graduated moving part 4 fully, respectively, ensuring that the instrument is set to zero. - ie to ensure that the reference line 10 on the moving part 4 is opposite the indication 0 of the handle 2, when said part 4 is at full travel, to the left or to the right according to the drawing.
  • the graduated moving part 4 is screwed in fully then unscrewed by the number of turns and possibly by a fraction of turns corresponding to the requested adjustment and the sliding stop 9 is moved to come into contact with said part 4.
  • a tachometer adjusting screwdriver according to the invention can be produced in various dimensions and with various graduations.
