Definitions

  • a cassette music box comprises a base housing a [30] Forelgn Apphc auon Pnomy Dam motor with a gear train, and a comb-like plate with June 15, 1973 Switzerland 8692/73 tuned teeth
  • a cassette removably fittable in a recess of the base includes a pin roller and a driving wheel U-S. Clrespectivel g g Said teeth and the g 51 I Cl G10f 1/06 y [3L train when the cassette is fitted.
  • the tune may be changed by changing the roller by an axial sliding movement.
  • the comb-like plates are complicated and expensive to manufacture.
  • An object of the invention is to provide a cassette music box which avoids these drawbacks.
  • This cassette music box comprises a case or base including a motor, a gear-train operatively connected to the motor, and a comb-like plate with a plurality of tuned teeth.
  • a recess is provided in the case to receive a cassette having a hollow body of corresponding shape.
  • a roller member carrying a plurality of selectively disposed asperities is rotatably mounted in the cassette body, with said asperities and a wheel fixed for rotation with the roller memher being accessible through an opening in the cassette body.
  • Means are provided for releasably holding said cassette in said recess in a position in which (a) said gear train is in driving engagement with said wheel and (b) said asperities are disposed to operatively cooperate with said teeth upon rotation of said member.
  • roller member designates both a roller carrying asperities, and a roller about which an endless belt carrying the asperities passes.
  • FIGURE is a partly cut-away view of a music box and cassette according to the invention.
  • the music box shown comprises a hollow case or base 2 in which a substantially constant speed clockwork or battery-operated electric motor 1 is mounted.
  • Motor 2 drives a gear train including a toothed wheel 3 which is adapted, in use, to drive a toothed wheel4 fixed to a pin roller 5.
  • Case 2 also houses a comb-like steel plate including a plurality of tuned teeth 6.
  • Two pin rollers 5 and wheels 4 are mounted in a removable cassette with a body of rectangular parallelepipedic shape having two major faces and four minor edges. T-shaped openings provided in facing edges of the cassette body enable the wheels 4 to be accessiblefor meshing with wheel 3 and the asperities 5 accessible for operative cooperation with teeth 6.
  • the other edges of the cassette body are each provided with an elongate groove 8 terminating with an enlarged end 13.
  • These grooves 8 are so disposed that by cooperation with a rail-forming protuberance in the recess of body 2 adapted to receive cassette 7, the cassette 7 can be introduced in said recess with a sliding movement in a direction perpendicular to the face of an opening 15, but only for a given orientation of the cassette in which wheel 4 will come to mesh with wheel 3.
  • a manually releasable detent 10 which engages in an end 13 of groove 8.
  • the music box also comprises a device 12 for locking the gear train and hence stoppingmotor 1.
  • Device 12 is associated with a control member 11 which is spring biased to a locking position in which it protrudes in the cassette-receiving recess.
  • the cassette body moves the control member to and holds it in an unlocking position in which the motor 1 is freed, whereby wheel 3 drives wheel 4 and roller 5.
  • the music box also includes means for protecting the comb-like plate, formed by a magnetized plate 14 disposed lengthwise of the comb-like plate and having a slot through which teeth 6 pass. Should a tooth 6 be accidentally broken, the broken-off tooth will be magnetically held on plate 14, so that the risk of jamming'the motor 1 will be reduced.
  • the case or base 1 could have different shapes and the cassettes could be inserted in recesses with a different disposition.
  • a cassette music box comprising, in combination: a case including a motor, a gear train operatively connected to the motor, a comb-like plate with a plurality of tuned teeth, and means defining a recess in the case for receiving a cassette; and at least one cassette, said cassette including hollow cassette body adapted to fit in said recess of the case, at least one roller-like member rotatably mounted in said body, a plurality of asperities selectively disposed on said member, a wheel fixed for rotation with said member, and means for defining at least one opening in said body through which said asperities and said wheel are accessible; said combination further comprising means for releasably holding said cassette in said recess in a position in which (a) said gear train is in driving engagement with said wheel and (b) said asperities are disposed to operatively cooperate with said teeth upon rotation of said member.
  • a cassette music box in which said cassette body is of generally rectangular parallelepipedic shape comprising two major faces and four minor edges, said at least one opening being provided in a first one of said minor edges, the roller-like member being pivotally mounted in opposite second and third of said minor edges adjacent said first minor edge, said recess and said cassette body including complementary means defining a rail for guiding said cassette body into and out of said recess with a sliding movement in a direction perpendicular to said first face.
  • a cassette music box according to claim 2, com prising means for defining at least one further opening in the fourth edge of said cassette body, a second rollerlike member provided with a wheel and carrying selectively disposed asperities being pivotally mounted in said second and third edges adjacent to said fourth edge, and said guiding means including a protuberance in said recess and means defining an elongate groove along each of the second and third edges of said houslocking position, said cassette body being adapted to hold said member in the unlocking position when the cassette is fixed in said recess in said position.
  • a cassette music box in which said comb-like plate is in steel and said case includes means for protecting said comb-like plate, said protecting means including a magnet extending lengthwise of said comb-like member.
