Definitions

  • ABSTRACT A record player cyclic mechanism having a driving gear centered under a record rotary plate coupled with a bigger gear provided with a perimetral toothless section which causes the stopping of the bigger gear after a full turn, this determining the cycle of opera tional movement and including a control device mounted on the bigger gear adjacent to the perimetral toothless section comprising a plate placed in the upper face of the bigger gear in a plane parallel thereto and freely pivoting on the face through a pin.
  • the plate is provided with a vertical nail oriented upwardly and in a negative angle with relation to the turn of the driving gear on which it can rest.
  • the plate also is provided with a quadrangular notch in which enters from its lower part a plane spindle projecting through a window provided in the bigger gear.
  • the spindle is fixed perpendicularly to a plane cam, parallelly horizontal to the plate, the cam being pivotable under the bigger gear independently of the plate
  • the pin is common to the cam and the plate.
  • the cyclic mechanism initiates the start up of the automatic record players and the successive change of records. in combination with other position elements such as the record-press arm.
  • This gear is provided with a channel that. as a cam, displaces a mechanism acting in the start-up and in the change of records.
  • the gear must perform a complete turn for the start up and the change of each record.
  • the best known structure of this type of mechanism is that in which the gear, provided with a toothless perimetral section combines with another smaller driving gear.
  • the driving gear is placed in the center of the plate which, in turn. clutches through its external edge with the motor pulley.
  • a further object of this invention is to provide two parts acting in reciprocal combination without appealing to mutual frictions or other non-accurate mechanisms.
  • FIG. 2 shows a perspective view of the device in its operative position free from the gear which is slightly outlined in order to compare it as a whole;
  • FIG. 2A is a diagrammatic plan view showing the re lationship of the flange and drive gear of the present invention
  • FIG. 3 shows a side elevational view of the device mounted
  • FIG. 4 shows a perspective view of the device, from a side opposite to that appearing in FIGS. 1, 2 and 3.
  • the device 100 is mounted on gear 1, common to many types of automatic record changers, adjacent to the perimetral sector I where a toothless flat section is provided.
  • the device is formed by a plate 2 placed over the upper face of the gear within the periphery thereof in a plane parallel to the plane of the gear.
  • the plate pivots freely on a pin 9 and is held there by a security spring 3.
  • the plate 2 has a vertical nail 4 oriented upwardly and in negative angle in relation with the turn of a smaller driving gear 5.
  • the plate 2 has a notch 6 in its edge 2', where a rectangular spindle 7 projecting from the cam 8 is inserted, crossing the window I provided in the bigger gear 1.
  • Cam 8 is in a horizontal plane parallel to plate 2 and is positioned under the lower face of the gear 1, and pivots about pin 9. It is an indispensable condition that the plate and the cam turn independently.
  • FIG. 2 plate 2 and cam 8, independent of gear 1, the entrance of spindle 7 into notch 6, the curve 8' shaped in the back of cam 8 and the subsequent position in negative angle of vertical nail 4. in relation with smaller gears 5 feed.
  • FIG. 3 In FIG. 3 is shown record rotatory plate 10 connected to smaller gear 5 which in its flat upper projection or neck has a tooth ll placed at a height coinciding with vertical nail 4 of plate 2.
  • FIG. 4 shows the interrelation of the ensemble of parts allowing the movements initiating each operative cycle of gear 1.
  • gear 5 which is a driving gear will turn.
  • a record player cyclic mechanism having a driving gear centered under a record rotatory plate coupled with a bigger gear provided with a perimetral toothless section which causes the stopping of the bigger gear after a full turn, thus determining the cycle of operational movement and including a control device mounted on said bigger gear adjacent to the perimetral toothless section comprising a plate placed in the upper face of said gear in a plane parallel thereto and freely pivoting on said face through a pin, said plate being provided with a vertical nail oriented upwardly and in negative angle with relation to the turn of the driving gear on which it can rest, said plate also being provided with a quadrangular notch in which enters from its lower part a plane spindle projecting through a window provided in said bigger gear, said spindle is fixed perpendicularly to a plane cam, parallelly horizontal to record placed under said driving gear.
