    摘要： The invention relates to a change spindle for use in an automatic record changer, and more particularly to a spindle having a hollow cylindrical body and a central operating rod which is axially movable in the cylindrical body and co-operates with elements for supporting the records. The elements are retractable into the cylindrical body and support the records in spaced relation.

    摘要： A simplified phonograph record changer mechanism is provided wherein after the last record has been played, a shut-off stud on the cycling gear contacts a shut-off lever. This imparts a movement to the shut-off lever and causes it to coact with other parts of the changer mechanism effective to move the changer motor power switch to its OFF position. The shut-off lever is positioned to interfere with the shut-off stud''s path of travel only after the last record has been played which is determined by the position of the stabilizer arm stab shaft. At all other times, the shut-off lever is positioned so that the shut-off stud will not contact the lever.

    摘要： A selector cam varies according to its setting position, the distance of the pivot of a stop lever having a stop face at end, from a pickup-positioning pin on a pickup plate pivotally movable with the pickup spindle for any given position of the pickup arm. The stop lever is lost-motion coupled to a drive lever transmitting the movement of a cam-follower to the pickup arm control lever so as to move the stop lever clear of the path of the positioning pin during the outward movement of the pickup arm and producing, before the stop face of the stop lever is withdrawn from this path to permit playing of a record, a wiping movement of this face, this face being cam-shaped to first ensure engagement of the pickup-positioning pin with the record groove and then gradually release any resilient forces built up during this initial period. Friction drive for the pickup plate during the positioning movement is effected by a return arm which is friction-pivoted to the pickup arm control plate and which, at the beginning of the inward movement, clasps a pin of the pickup plate in pincer fashion.

    摘要： In an automatic record changer in which the pickup-arm movements are controlled by a cam groove and the record release mechanism is operated by a circumferential cam, the engagement of the camtrip pawl at the beginning of automatic play, the transfer of the hand-control lever from an AUTO position to a MANUAL position during the first revolution of the cams, and the retention of the pickup arm in the rest position and eventual switching off of the motor at the end of a revolution in which no record is available on the shoulder of the record spindle, is effected with the help of a cycle-control lever capable of pivotal movement about and longitudinal movement relative to a fulcrum pin, this lever having an edge formed with a sawtooth whose face causes the cycle-control lever to follow the longitudinal movement of a catch lever linked to the switch lever as the latter is moved by a hand lever from OFF position to a manual or auto position and retained there by steps in an aperture of the mounting plate, movement of the cycle-control lever to the latter position producing, via a resilient cam member, engagement of the trip pawl for a revolution of the cam wheel, whereafter engagement of a pin of the cam wheel with a cam acting on the cycle-control lever lifts lug 24 clear of auto step 29 causing the lug to return resiliently to the manual step. A release lever connected to the record-release pawl, after release of the last record, beyond its position of rest, engaging the cycle control lever to lift its sawtooth off the pawl of the catch lever, thereby tilting the catch lever to move the cam into the path of the camwheel pin which, near the end of the revolution of the cam wheel, causes return pivotal movement of the cycle-control lever, lifting the lug of the catch lever off the manual step, thus allowing resilient return of the switch lever and hand-control lever to their STOP positions.

    摘要： THE INVENTION RELATES TO A PLASTIC SPINDLE FOR A RECORD TURNTABLE. SPECIFICALLY, THE INVENTION RELATES TO A SPINDLE FORMED EITHER BY INJECTION MOLDING OR OTHERWISE MOLDING TO SPINDLE SHAPE OF HIGH-STRENGTH PLASTIC WHILE STILL ALLOWING THE SPINDLE TO FUNCTION IN EXACTLY THE SAME MANNER IT HAS HERETOFORE. THE ROUND PORTION OF THE INTERIOR IS TAPERED, AND A RING OF THE SAME MATERIAL AS THE INTERIOR, PREFERABLY MOLDED IN THE SAME DIE, IS PUSHED INTO THE OPEN END TO HANDLE THE NECESSARY TAPERED HOLE, YET ASSURES FULL SUPPORT. THE BLADES OF THE SPINDLE ARE TO BE LEFT AS STAMPINGS, SINCE THE WEIGHT IS ADVANTAGEOUS IN THE OPERATION OF THE SPINDLE. A TEFLON TUBE HEAT SHRUNK OVER MOLDED RINGS FORMS THE BASE SPINDLE BEARING. THE PLASTIC VALUE IN FILTRATION OF NOISE IS WELL KNOWN.
