Abstract

462,271. Gramophones. ZAN, T. June 29, 1936, No. 18047. [Class 40 (ii)] Automatic repeating-mechanism comprises a lifting arm 5 pivoted at one end 5a and having the other end engaging the tone-arm 3, the lifting arm being slotted to engage a crank-pin 7 adjustably fixed to an inclined disc 6, so that when the disc is rotated at the end of the playing of a record the arm 5 is moved both vertically and laterally, raising the tone-arm, returning it to the starting-point of the record and depositing the sound-box thereon. The disc 6 is connected by gearing to a roller 24 pivotally mounted at 23 on a three-armed lever 25, 26, 27, the roller being normally out of contact with the turntable 1, while a pin 31 on one of the arms of the lever lies in a notch 32 in the disc 6. When the sound-box reaches the end of the record, the tone-arm strikes an adjustable extension 33 of the member 26, thereby causing the roller 24 to engage the turntable and moving the pin 31 out of the notch 32. The disc 6 is thereupon rotated and the disc and crank-pin effect the raising, swinging, and lowering movements of the tone-arm. A light spring may be provided to push the needle into the sound-groove when it has been lowered on to the margin of the record.
