Returning sound-box to starting point; stopping.- A repeating-attachment for gramophones, of the kind in which a hinged radial track arm is tilted at the end of a reproduction so as to return the sound-box, is provided with means for positively lowering the track arm after the return of the sound-box. The track arm 10 hinged on an horizontal pin 10 carries at its outer end a pivoted member 14 with two fingers 14, 14 lying on opposite sides of a threaded post 13 secured to a baseplate 13, which rests on, and is driven by, the record-disk 3. The pivotal movement of the member 14 is limited, and it is held in either extreme position by a spring 14. The post 13 has right and left hand spiral threads 13, 13, the right-hand thread 13 terminating at its upper end in a projecting cam 13, and both threads terminating at their lower ends in a circular groove 13. The soundbox is moved inwards quickly at the end of a record by a spiral groove 3, which may be formed in the record or in an arm pivoted to the base 13. An arm 16 attached to the sound-box strikes a projection 14 on the member 14, thereby removing the finger 14 from the circular groove 13 and engaging the finger 14. The right-hand thread 13 then raises the track arm into an inclined position, and the sound-box is lifted about the pivot 7a by the engagement of the track arm with a roller 11 carried by a bracket 12. The roller 11 then runs down the track arm, and the sound-box is carried to the edge of the disk. When the finger 14 reaches the cam 13, the member 14 is swung back again so as to engage the opposite finger 14 in the groove 13, thereby lowering the track arm into an horizontal position. Near the hinged end of the track arm 10 is pivoted a hand-controlled lever 17 having two projecting horns 17, 17, either of which may be placed in the path of the needle of the descending sound-box 4, which is thereby arrested at a point suitable for starting another reproduction. The lever 17 is locked in position by a tongue 17 engaging notches 17 in the underside of the track arm. When the lever 17 is swung over so that its tongue 17d engages the right-hand notch, Fig. 3, the horn 17 lies beneath a brake arm 8, and in this case the effect of the tilting of the track arm 10 is to apply the brake 8 and to stop the turntable.
