ABSTRACT:
An improved toy phonograph in which a phonograph record is mountable on a rotating turntable with sound being picked up from the record by a pivoted pickup arm which is direct contact with a speaker cone assembly which presses the pickup arm into playing engagement with the phonograph record. The pickup arm is automatically reset to the periphery of the record upon completion of play of the record by engagement of a protrusion on the pickup arm with a protrusion on the floating cam at the end of the play of the record. The floating cam is biased into nesting engagement with a congruent cam fixedly mounted on the turntable for rotation therewith with both cams being a triangularly sloped peripheral engageable cam surface for substantially 180.degree. of the peripheral circumference of the cams. The stopping of the floating cam during rotation of the turntable causes the floating cam peripheral cam surface to ride up the sloped surface of the other cam thereby driving it out of nesting engagement therewith raising the floating cam a sufficient amount to contact the speaker cone assembly and lift it out of biasing engagement with the pickup arm whereby the pickup arm, which is normally spring biased towards the periphery of the record, automatically returns to the periphery of the record thereby disengaging the protrusion on the pickup arm from the protrusion on the floating cam and, after reset of the pickup arm, thereby enabling return of the speaker cone assembly to biasing contact with the pickup arm pressing it into engagement with the phonograph record for enabling replay thereof.
