TALKING-MACHINE.

Specification of Letters Patent.

Application filed October 27, 1913. Serial No. 797,588.

To all whom it may concern Be it known that 1, CHARLES RUPPEL, a citizen ofthe United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Talking-Machines, of which the followingisg a specification. 1

My invention relates to improvements in talking machines, and more particularly to. amachine of this type which'dispen'ses with the horn and in lieu thereof directs the sound downwardly through an open dome.

A further'object is to provide an improved talking machine with improved means for driving the turn table and having improved means for regulating the speed thereof. I

A further object is to provide a talking machine with a sound box having rotary mounting, and which is provided with a weight adapted to hold the needle or stylus in proper engagement with the record,and which weight may be utilized as a handle to turn. the-soundbox and lift the needle or; stylus from the record. p 3 A further object'is to provide an improved construction-of cabinet which may be uti-' lized as a storage for records and a housing. for the motor as well as presenting an orna-- mental and attractive appearance.-

With these and other objects in view, theinvention consists in certain novel features i of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a viewin side elevation illustrating my improvements. Fig. 2 is aview in cross section on an enlarged scale on the line 2-2 of'Fig. 1 Fig. 3 is a fragmentary view in elevation showing the rear of the cabinet: with the-doors open to illustratethe gearing within the cabinet. Fig.4 is a View in'vertical section on the line 4-4: of Fig. 3; Fig. 5 is a fragmentary sectional detailview illustrating the manner of pivotally' sup-- porting the soundboxarm. Fig. 6 is a diagonal sectional view through the dome of the cabinet, and Fig. 7 is a View in eleva-:

weight partly in section. I

1 represents my improved cabinet which= tion of the sound box showing-its attached V tan ular portion 7 of the cabinet is provide at a 1 four sides with hinged doors-'3,;so that.

King gear 0 access may be readily had to the interior thereof.

A space inclosed by the doors 3 houses my -,1mproved weight motor, and is also divided :by vertical and horizontal partitions 4 and -5 soas to provide a chamber 6 in which records are stored.

.Ontop of the lower rectangular portion 7, four hollow standards 8 are located and sup- ;port at their upper ends, an ornamental :frame 64 above which is located a dome 9. A turn table compartment 10 is formed on ;the top of the lower rectangular portion 7, :and is provided atall four sides with hinged ldoors 11 so that access may be readily had to the compartment.

In the turn table compartment 10, a circular turn table 12 is located and is secured upon zthe upper end of a vertical shaft 13 which extends through :the rectangular portion 7,

and is provided at its lower end with a gov -.ernor 14 toregulate the speed of the turn table. This governor. 14 is adjusted by means of a vertical screw-threaded rod 15 which has a milled head 16 onits upper end which may be manually turned to adjust the rod vertically. The rod 15 has a knob 17 on its lower end which is engaged by a disk 18 on the governor as the arms 19 of the latter swing outwardly so as to limit the speed'of :the shaft.

crown gear 21 on a short shaft 22, the latter shavin .a'pinio'n 23 thereon to mesh with a large firivin gear 24: constituting the drivmy improved weight motor lwhich will now be described. The gear 24 is loose ona horizontal shaft 25, but is provided with-a spring-pressed pawl 26 in engagement with a ratchet wheel 27' on the shaft 25, so that said shaft 25 when turned in one direction will impart motion to the gear 24: y On the shaft 25, three drums. 28 are secured, and three cords or other flexible connectingdevices 29 are secured to and wound A pinion 20 on shaft 13 is driven'by a.

.upon the respective drums. In three of the hollow standards 8, weights 36 are adapted to move vertically, and in the upper portions of these standards, pulleys 31 are provided over which the respective cords 29 pass. These cords 29 pass over idle pulleys 32 in the lower portions of the standards and {thence around idle pulleys 33 on a shaft '35 is interposed between one of the pulleys 34, and one of the pulleys 32, to properly direct the cord to one of the standards as seen most clearly in Fig. 2. In other words, the pulleys are so arranged that the downward movement of the weights compels all of the cords to. unwind from the drums, impar. a rotary motion to the shaft 25. c The cords 2) are wound upon the drums 28, and the weights elevated when my improved winding mechanism now to be. described is operated. The shaft 25 is provided with a ratchet wheel 36 which is engaged by a springp'ressed pawl 37 on a disk 38 loose upon said shaft 25, but fixed to turn with a gear 39. This gear 39 is connected by a train of gearing 40 with a winding shaft 41, and the latter is provided with a key 42 to connect a crank arm 43 to the shaft, so that when the latter is turned, the train of gearing will be operated to turn the drums and wind the cords thereon, elevating the several weights. During this winding operation of the drums, the ratchet and pawl 26 and 27 permit the shaft 25 to be turned without transmitting motion to the driving gear 24. As above stated, three of the standards 8 are occupied by the weights 10. The

- fourth of these standards is occupied by a sound tube 44 which at its upper end extends into the dome 9, and is slightly enlarged as shown at 45. The enlarged end of the tube 44 has an upwardly projecting pin 63 on which the dome 9 is supported and'the latards 8 are occupied by the weights 30. The dome serves to amplify the sound and throw the sound waves downwardly and outwardly, softening the tones and distributing the sound uniformly in all directions.

The sound box arm 46 is pivotally supported at the lower end of the sound tube 44 by means of a journal 47 which bears against the lower face of the arm 46, and is adjustable in a bracket 48 by means of a set screw 49. It will be noted that the arm 46 has an upwardly projecting elbow 50 which extends into the sound tube 44, so that the arm 46 swings freely, the journal 47 and the extension 50 within tube 44 operating a a rotary mount for the arm. When it is desired to disconnect the arm, it is simply necessary to lower the journal 47 when the elbow 50 can be dropped down out of the tube 44.

On the free end of the arm46; my improved sound 51 is located. This sound box 51 is provided with a tube 52 having rotary mounting in the box as seen most clearly in Fig. 7. The tube 52 has an intern gral disk 53 anda removable disk ffl flocated within the'sound box. One wall 55 of the sound box is located between these disks 53 and 54, so that while the parts are firmly held togethe the tube 52 acts as a journal to allow the ound box rotary movement thereon. The tabs .52 is connected to the arm 46, and as said arm has no upward pivotal movement, the rotary mounting of the box allows the needle or stylus to be raised and lowered relatively to the record (not shown) on the turn table 12.

The sound box is provided with any approved stylus bar 56, having a set screw 59 therein to hold the stylus or needle in place.

On one side of the box 51, I locate a weight 60 which operates to hold the needle or stylus in proper engagement With the record. This weight 60 may-constitute a hollow ball which may be filled with shot 61 to give it the proper weight. A screw 62 serves the double function of closing the 30 opening in the ball and also connecting the ball with the sound box. The ball 60 therefore gives the proper weight to hold the needle'on the record and also serves as a handle to permit the sound box to be revolved to lift the needle ofii the record.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
