MEANS Foa n EooRDING nnrrto cucine soumis;

were@ citizen 'of United States, residing at l lleijrfork,the county andState of New -.York, havelinvented a new and useful Means forRecording and Reproducing Sounds, of which the following is a specification.

My invention consists in the novel features hereinafter described.

and sundry parts thereof,

The objects of my improvement are.: First: V'jlo provide a means for recording ,and reproducing sounds, which may be readilyl attached to sound'flreproducing machines."

the' cabinets of standard Second.: To improveithe 'sundry/ details of said. meansV for recording and reproducing sounds.

Third' To provide a ready means Vforproducing records of sound, which may be employedpfor educational and other puri oSeS.'\VV (Fourth:- To have said means simple, du-

rable and inexpensive.

.I attain these objects by the .mechanism4 illustrated in the drawings," or by; anymechanical equivalent orcbvious modification ofthe sanie.-

' Inp the drawings Figure 1 is a sectional -.elevation 'on .thelline A4-B .of Figz2nofmy net of a: standard sound reproducing ma.

Said y travelingg; bridge 25is shown as carrying the vertical pin 27, whichv engages the slotted arm 28, which forms the extenthe bracket 30 by meansof the pin 30a and the spring clamp 35. Said' bracket 30. is to said hollow ,arm 15 by means of the straps 31 and 32,'which eX- tend on the underside of said hollow arm 15.

Each of said straps 31 and 32 is shown asv pivotally connected to vsaid bracket '30 on one side thereof and locked lthereto oiithe other side by means of the strap boltsa52, in 27 on said slotted arm 28 will cause said ollow arm v gfto swing around'its pivot 16 as an 1 axis, and that the motion of said arm Will be reduced by said Worm 43 and Wheel 44: from the rotary motion of the card 48, thereby producing an etlicient means for recording the sounds.

Thedirection of the threads of the feed A screw 24 maybe made such as to cause said arm 15 to swing toward the center of the card for recording sounds. i

Said bracket is shown in Fig. 1 as havin an extension 33, which reaches over the swivel 34 of the goose neck 36; and the inner end 4l of the goose neck 36 is shown as connected to said rider 29 by means of the link 37 and pin 38; 38 is a sleeve-or filler-ring shown in Fig. 2 as placed on said pin 38 between said rider 29 and the link 37. The sound box 39 may be connected directly to the traveling bridge 25 instead of to the swivelingfarm 15.

Many other changes could be made in the design and details of my means for recording and reproducing sounds Without departing from the main scope of my invention.

I do not therefore restrict myself to the form of the details as shown; but I intend to include also all mechanical equivalents and reasonably obvious modifications of the same.

What I claim as my invention and desire to secure by Letters Patent 1s:

, 1. A means for-recording and reproduc-4 lng sounds adapted to be detachably mountfed on the cabinet mclosing the spring motor and vertical shaft of a standard sound reproducing machine, said means comprising a sound box andstylus', a turntable adapted to be attached to said shaft and to have its upper surface extend above the end of said extending inwardly, 'a recording card hav-I ing two parallel edges adapted `to fit between sa-id Z-bar guldes and under said upper flanges, thereby beingladapte'd to be readily inserted 1n position on said turntable and to recelve a posltive motion from said Z-bar guides and a means for transabove the end of said shaft, thereby beingadapted to receive said card on said "surface, a means for transmitting positive motion from said turntable to said card, a metal plate secured to said card at the center thereof, a revolving` membervhaving fat one end thereof a coupling adapted to bemletachably connected to said plate, and a means for operatively connect-ing' `the other end of said member to said sound box.

3. In a means for recording and reproducing sounds adapted to be detachably mounted on the cabinet inclosing the 'spring motor and vertical shaft of a standard sound reproducing machine, a sound 1Jox and stylus, a recording card, a turntable adapted to be attached to the shaft of said "cabinet and to have its upper surface extend above the end of said shaft, thereby being adapted to receive said card on said surface, a means for transmitting positive motion from said turntable to said card, a .metal plate secured to said card at the center thereof, said plate having multiple openings, a revolving member., a means for operatively connecting one end of said member to said sound box, a coupling at the other end of said member. and multiple pins in said coupling adapt-ed to fit said openings, thereby dctachably connestingl said member to l,said plate.
