Specification of Letters Patent.

Patented Sept. 10,1907:

' To all whom it may concern:

Be it known that I, HENRY KOCH, a citizen of the United States, and a resident of Rahway, county of Union, and State of New Jersey, have invented certain new and useful Improvements in Talking-Machine Attachments, of which the following isa specification. My invention relates to the class of machines commonly knownas talking machines and has for its ob- 'ject to provide machines of this description with a 10' stylus pended claims.

Reference is to be had to the accompanying drawings in which Figure 1 is a side view of as much of a talking machine as is necessary to illustrate my invention and Fig. 2 is a sectional view thereof on an enlarged scale taken. on the line 22 of Fig 1.

A represents the sound conducting tube which carries at its free end the usual reproducer or sound box 137 The other end ofsaid tube A is journaled in a bracket 0 which is secured in any Convenient manner to the talking machine proper. This bracket C also carries the customary amplifying horn D which is in communication with the sound conducting tube A. The sound box B may be of any ordinary construction and is provided with the usual stylus arm ll secured to the diaphragm B and carrying the stylus holder 11 E represents a portion of the talking machine to which is secured in any convenient manner a guiding member F provided with a slot l". A plunger G is arranged to slide in saidguiding member F and is provided with an operating handle G which extends through the slot F of the member l This slide or plunger G is maintained in its lower position by a spring H one end of which abuts against the guiding member 1" and the other end of which engages a washer I carried by the plunger G. The plunger G is provided with a receptacle or recess J of a'tapering shape, so as to accommodate and hold the stylus K.

L is a holding catch pivoted at M to the stylus holder B and adapted to lock the stylus K in the holder H The catch L is provided with a finger piece I/ and is held in its locking position by a spring N.

O is a positioning fork attached at a convenlent-point to the talking machine E and adapted to engage the 1 sound-conducting tube A. The fork 0 maybe made separate from or integral with the guiding member F as desired. l

In operation to insert the stylus K in position in the stylus holder B, the said stylus K is lirst placed in the receptacle .l of the plunger G with its point down. The tube A is swung on its pivot in the bracket C and then raised and placed in the fork 0, it being understood thatthe tube A is so constructed as to be capableof swinging in a vertical as well as a horizontal plane. It is to be further understood that the fork O is arranged in a plane substantially at right angles,

that when the tube A is placed therein the stylus holder B will be directly over the receptacle .l in the with the plane of the sound-box and is so located plunger G. In other words when the tubeA in the fork 0 one of the members of said fork will engage the tube A at the rear thereof and the other member of said fork will engage the tube at the front thereof and the stylus holder will register with the stylus K in the plunger G. The plunger G is then pressed upward through the medium of the handle G and the stylus K inserted into the holder B where it is hold by the holding catch L. The holding catch is beveled at its lower portion so that the stylus on being pressed upward will be guided into proper position. It is to be understood that the receptacle .l of the plunger G is so proportioned that the stylus K will extend just far enough therefrom for correct positioning in the stylus holder. To aid in this the slot Ff is also in correct proportion. After the selection has been played on the machine and a new stylus is desired the finger piece I/ of the catch L, is pressed toward the sound box thus releasing the stylus just used and the above operation is repeated.

With my device a new stylus may be quickly insorted in the stylus holder and the danger of pricking the fingers is done away with. It is to be understood that instead of the positioning fork 0 an ordinary stop may be used, the only requirement being that the sound conductor or tube A be stopped at a point where the stylus holder is registry with the receptacle in the plunger G. I

Various modifications may be made without departing from the nature of my invention as defined in the claims. I I- claim and desire to secure by Letters Patent:

l. in a talking machine, the combination of a movable sounil-conducting tube, the sound box carried thereby and the stylus-holder on the sound box, with a support in permanent engagement with said soumbconducting tube, another support adapted for temporary engagement with said soulid-conducting lube and a stylus-inserting device which registers with the st \'lus-holder:when the sound.
