TALKING-MACHINE.

Patented Dec. 31, 1912.

To all whom it may concern:

Be it known that I, FRANK L. DYER, acitizien of the-United States, and a resident of Montclair, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Talking- Machines, of which the following is a description.

My invention relates to talking machines, and my object is to produce an improved device for feeding the reproducer and stylus carried thereby across a rotatable sound record of the disk type. I mount the sound conveying tube upon which the reproducer is carried by means of a ball and socket joint upon a fixed tube forming part of or Connecting with the amplifying horn. By this ball and socket joint construction, the reproducer is free to be moved across the face of the record to give the feed, and also is free to be moved toward and away from The movable hollow arm or tube carries a geared sector-or other desired engaging means, which, upon the lowering of the reproducer to cause the stylus to engage a record, moves into mesh with a gear or other driving device connected with the motor. Thus, the feedmay be engaged or disengaged at any point in the reproduction of a record by merely lowering the reproducing stylus into'tracking position upon a record or raising it therefrom.

My invention also'comprises an ir'nproved construction of a talking machine inclosed within a cabinet in which the sound amplifying horn is carried by the hinged cover of the cabinet. l l

. Other objects of my invention comprise the-construction of parts and combinations of elementshereinafter more fully described and set forth in the'appended claims.

In order that a clearer understanding' of my invention may be had, attention is hereby directed to the accompanying drawings forming part of this specification,` in which-K l i A Figure 1 represents a plan viewof a reproducing talking machine embodying my invention. Fig. 2 represents a horizontal cross sectiontaken on line 2--2 of Fig. 3. Fig. 3 represents a central vertical cross section through the talking machine shown in Fig. 1, certain parts being-shown in side elevation.` Fig. 4 is an'enlarged detail perspctiveview of certain parts shown in Figs. 2 and3. Fig. 5 is a vertical cross section of a talking machine similar to that shown in Fig. 3, pro-vided with a hinged cover carrying the amplifying horn, certain parts being shown in side elevation. Fig. 6 is a front view of the machine and cabinet shown in Fig. 5. Fig. 7 is a plan view of the same, and Fig. 8 is a side elevation, the cover being shown in raised position.

Referring to the drawings, the yreproducer 1is provided with stylus 2 mounted in any suitable way, and connected with the diaphragm o-f the reproducer as by lever 3l pivoted at 4 to reproducer 1, stylus 2 being adapted to track'a sound record 5 of the disk type mounted upon turn-table 6 supported by vertical :spindle 7 which is rotatably mounted in horizontal member 8 and is adapted to be rotated by motor 9 mounted upon shaft 10, as is common. Reproducer 1 is mounted upon the end of sound conveying tube 11 which extends horizontally across record 5 rearwardly from reproducer 1 and thence bends downwardly, as shown at 12, extending through an opening in horizontal member 8. The downwardly directed portion 12 of tube 11 is provided toward its lower end with a swelling 13 approximately spherical in shape. The tube 14 extends upwardly within the lower end ofdownwardly directed portion 12 of tube 11 andis formed at its upper end with an approximately spherical swelling 15 upon its exterior, which is adapted toit within the interior surface of spherical portion 13 of tube 12 to form a ball and socket joint. The lower .18 which is shown as 'a spur pinion mounted upon horizontal shaft '19. Motor shaft 10.-

which is su ported by bracket 2O from horil zontal member 8, has a large worm wheel 21. This meshes with a worm 22 mounted vertically which in turn meshes with a wormv wheel'. 23 mounted upon shaft 24 supported Tube 14 may be seby bracket 25. Shaft 24 has a worm 26 .part of the record, reproducer 1 is simply raised, the tube 11 swinging backwardly as ,surface 13 thereof slides over swelling 15 of tube 111, causing sector 28 to move out oi engagement with gear 18. When the stylus is moved back into operative position, the 'sector engages gear 18, whereupon, if the motor 9 is running, the stylus will be fed positively across the record. It desired, means may be employed to prevent lateral oscillation of hollow arm 11 about its ball and socket joint in a direction at rightangles to the plane of Fig. 3 of the drawings.

I have shown one such means in the drawings, in which a ring 30 is mounted. within fthe opening in member 8 through which tube 12 descends, surrounding spherical portion 13 of tube 12 but out of contact with the same, sutlicient space being left between swelling 13 and ring 30 to permit thenecessary movement of stylus 2 toward and away from record 5. A pair of pins axially in` line with each other, of which one isshown in Fig. 3 at 31, are secured in ring 30 and extend through swelling 13 ofl tube 12 to the inner surface thereof, tube 12 being rotatably mounted upon the inner ends of pins Ring 30 is slidablewithin a recess pro- K. .vided therefor in its seat in the lug 32. de-

pending from member 8, so that when stylus 2 is fed across the record, ring 30 turns in its seat and when the stylus is raised out of contact with the record, tube 12 pivots about pins 31, surface 13 sliding over'surface 15.

Tube 16 may b e integral with or connected to the horn or sound amplifier in any desired manner. As shown in the drawings, tube 16 bends upwardly as shown at 32 and joins the vertically rising portion 33 of the horn, which has a forwardly extending elbow 34. The machine is preferably mounted in a cabinet 35, to which cover 36 is hinged on the top thereof, as shown at 37. Sound amplifying horn 38 is secured within cover 36, having its exit end situated in the front side 39 of the cover, which isA rovided with an opening 40 within which the exit end of horn 38 fits. Elbow-34 of sound conveying tube 33 abuts against the'end4l of horn 38 when the cover is closed, as shown in Fig. 5, to form one continuous` horn. i

It is obvious that my invention is not limited to the particular details of construcinit-),215
