Definitions

  • VIBRATORY MOTOR 1 Filed Dec. 31, 1951 COIL VIBRATOR BLADE j PERMENANT MAGNET m ⁇ ⁇ m N V EN TOR.
  • This prior arrangement includes a blade-controlled current breaker, comprising at least one contact-piece rigid with the free end of the blade, a cooperating contact piece and means securing the latter to the blade, to make it execute an oscillatory movement with reference to the blade, under the action of the vibration of said blade, the second contact piece may e. g. be carried by an arm pivotally secured to the end of the blade, to rock in a plane passing through the longitudinal axis of the blade under the actual influence of the vibrations of the blade or tuning fork.
  • My present invention has for its object an improved embodiment of the movable contact piece in a current breaker of the type disclosed in my said copending specification, which embodiment cuts out in practice any objectionable friction.
  • the movable member the movement of which opens and closes the current breaker, is constituted by a simple ball made of magnetic steel. Said ball moves inside a tube and the amplitude of its movements is very small with reference to the amplitude of movement of the end of the vibrating blade.
  • the section of the tube wherein the ball moves shows the following novel features:
  • Said tube section is provided with a slot the edges of which form a raceway for the ball,
  • the cross section of the tube assumes the shape of a horse shoe magnet and the section is magnetized transversely so as to produce a magnetic field which constrains the ball to roll over the race under the action of magnetic attraction.
  • Fig. 1 is a longitudinal cross-section passing through the axis of the tube and Fig. 2 is a cross-section thereof perpendicular to the axis of the tube taken along the line 22 of Fig. 1.
  • l designates a rectilinear tube section inside which may move a ball 2 made of magnetic steel.
  • This tube section is rigidly secured to the outside of a vibratory blade V or to the arm of a tuning fork.
  • the tube section i is provided with a longitudinal slot 3 (Fig. 2) and it is constituted by an alloy of a magnetic metal so as to form a permanent magnet the magnetization of which is directed transversely with a north pole at N and a south pole at S.
  • the internal diameter of the tube I is slightly larger than that of the ball 2 which latter is urged by the magnetic field against the inner edges d and 5 of the slot 3, whereby said edges form a kind of raceway for the ball. It is thus apparent that the ball does not require a mechanical connection and moves over a predetermined path with a minimum amount of friction,
  • the ends of the tube section I are tapped so a to carry the outwardly threaded annular insulated members 6 and I that are also tapped inwardly for engagement by the actual contact pieces 8 and 9 rigid with the vibrating blade V and cooperating in alternation with the ball 2,
  • the oscillations of the ball will provide for the intermittent operation of the coil through any source of energy, such as a battery for constraining the blade to vibrate at a constant amplitude.
  • a current interrupter for said circuit comprising a permanent magnet assuming the shape of a longitudinally slotted rectilinear tube, the poles of said magnet being formed by the cooperating edges of the slot of said tube, said magnet being secured to said vibratory member with its axis lying in the general plane of vibration of the latter, electric contact pieces insulatingly carried at the ends of said tube and connected in parallel in said circuit, a
  • a current interrupter comprising a permanent magnet having the shape of a longitudinally slotted rectilinear tube, the poles of said magnet being formed by the cooperating edges of the slot of said tube, said magnet being secured to said vibratory member with its axis lying in the general plane of vibration of the latter, electric contact pieces insulatingly carried at the ends of said tube, a ball of magnetic material the diameter of which is slightly less of that of said tube positioned in said tube and being adapted to roll over the cooperating edges of the slot to reciprocate between said electric contact pieces and to alternately close the circuit between said contact pieces and said tube as the vibratory member is vibrated.
