neck and the selector 27 ,.tion, having dropped down yshaped bottom of the swings the neck up and below the caught needle, this construction permitting of the entrance of the needle from below and the expelling of the same upwardly.

To the tone arm l attach a bracket 23, the free end of which supports a needle storage box 24, the storage box having a hopper shaped bottom 25 itted with a transverse slot 26 which receives a vertically disposed needle selector 27, the selector having the ends slidably mounted in the The upper edge thereof is provided with a lengthwise extending groove 28 and the sides are vertically slotted as indicated at 29 and 30. The ends of the latter slots limit the up and down movement ot the selector. The selector is positioned such that it will take a position directly beneath the needle carried by the needle arm when the sound box is rotated, as later described. This latter positionfis shown in Figure 3.

'A lever 31 is pivotally attached to a bracket 32 carried by the tone arm and one end of the lever is Jformed into a finger 33 neck, whilst the other end thereof is pivotally attached by a pivot bolt 34 to the lower end of the needle selector. A brace bar 35 reinforces the brackets 23 and 32.

`lZVhen this device is to be used one places a number ofV needles in the storage box or compartment with the points thereof all `Assuming that one has just inished playing a record and desires to change the needle; at this time the used needle is on the record and the neck is in playing position. Gonsequentlythe finger 33 is free of the is in its lower posiunder the action of its own weight and the weight of the long In this position of the Q8 is at the bottom of the box 9A and by virtue of the hopper box the needles to occupy the position the selector. `When one and back to bring the sound box to non-playing position, he brings naturallyv roll in previously held byy the neck into contact with the linger 33 and to turn the needle arm from the position shown in dotted outlinein Fig. l to that such movement bringhas just been playing,

shown in full outline, ing the needle, which to a position directly above the new needle carried in the groove 28. Consequently, a

" y:"down movement of the oldneedle, brought about by rotating the sound box, will cause 1,498 ,cos

the new needle to force the old needle out through the clearance space 22Qand the new needle to take the position occupied by the discharged old needle. Having accomplished this, one then rotates the sound box back to bring the needle arm and needle to the position shown in dotted outline in Fig. l, in which position the ball is in the slot 17. Then, by rotating the, neck in the usual manner he can bring the new needle into playing position in contact with the record.

Obviously, the attendant has nothing to release, but simply has to manipulate the sound box and neck, in the manner disclosed, to insert the new needle. It is, ofcourse, to be understood that the spring 2O is suliiciently strong to hold thev inserted needle tightly in place for playing purposes.

What I claim as my invention is: 1 l. The combination with a rotatably mounted sound box, and the needle carrying arm carried thereby and rotatable therewith, of a needle storage box, operated means for selectively picking ia needle from the storage box and elevating the same to an exposed position in the path of the rotated needle arm, and a spring catch associated with the needle, catch being adapted toreceive and hold the needle selected from the storage box in the rotation of the sound box. y p l 2. The combination with av rotatably mounted sound box and the needle arm carried thereby and rotatable therewith, of a spring catch associated with the needlearm and adapted to receive and hold a needle, a suitably mounted needle storage box' and means for selectively picking a needle from the storage box and bringing the same into the path of travel of the rotated needle arm, whereby the selected needle will be caught Ey the catch in the rotation of the sound 3. The combination with a tone arm, a neck pivotally carried by the tone-arm, a sound box rotatably mounted on the neck mechanically said spring and the needle arm carried by and rotatable with the sound box, of carried by the tone arm, slidably mounted in the box and adapted when raised to pick up a needle and-bring the same to an exposed position in the'path ot the rotated needle arm, a pivoted lever carried by the tone arm pivotally connected to the selector and engageable with the neck and adapted, in the swinging movement of the neck, to operate the selector, vand a spring catch carried by the needlearm and adapted to catch and hold `the exposed needle in the rotation of the sound box.
