Specification of lie tters ratent.

To all whom it may concem:

' Be it known that I, Winner) CLEVE- LAND, a citiien of the United, States, and a resident of F all River; in; the county of Bristol and State ot Massachusetts, have invented a new and Improved .ltepeating Device" for Phon'ogra hs of which the followzt 1111, clear, and exact description;

he invention relates to" phonographs of the net record t pe, and as (mee is a)- provide a new and improved, repeating device Whichis very simple and durable in coiiisth'u'etion, easily set for various sized disks and arranged to automatically swing the to ne arm upward at the 't-ime-the stylus- {namesake end of the sound groove to lift theazyl s out oi the said groove, to then svil'i ng the. tone arm outwardly and then dotvnyvardinto active position relatively tothe record to engage the stylus with the nini of the sound groove.

fi e "'r to produce the desired result useis made of a normally inactive eam'le- 've'r mounted to swing up, and down and sidewise the cam end "of the said lever hemg adapted to engage the tone arm, actuatingmeans control-led by the tone arm to swing the cam end and with it the tone arm upfw'ard, and the other end of'thelever ownward at the time the stylus reaches the end of the sound groove; and continually driven means adapted'to engage the lowered other end of thesaid cam lever to impart a awingi g motion to the" same to swing the, raised, tone armolitward; v

A practical, embodiment of the invention iiifiepresehted iii-the accompanying drawfoi'ining a. part of this specification,

On the'frane 10 of .a phonograph of the disk record type is held a bearing l'l'for the base 12 0'? thetone arm 13 to swing on, and the said tone arm'13 carries'the usual .sound box It provided with a stylus 15 'adapted to en gage therecord 16 held on top ei the revolul llB platform 17. The platform 17 is mountel on a shaft 18 formlng part of a motor 19 of any approved construction preferably aspring motor mounted on the frame 10.

Iward end 24 of the lever 20 is adapted to be engaged ty either of two friction rollers 25 mounted on the to of an arm '26 se-" ,c' ired on a shaft 27 orming part of the motor 19, hi it rotating at a slower speed than the sha1't 18 .carryingthe platform 17. Normally the outer end 240i the cam lever 20extends abovethe friction rollers 25 so that the latter doInot efiectthe' cam lever until a. swinging motion is given to the said cam leverto move the end 24 into the path of the roller; 25. .VVhen this takes place a swinging nation is given to the cam lever 2'0 toswing the letter from the normal inactive position shown sition shown in Fig. 2.

-The rear end of the cam lever s provided on its top with a, cam having a step-like portion 31 at theright-hand slde, that is, toward the tone arm 13.' The cam 30 is adapted to engage with its step 31 v one arm 32 of the bell crank lever 33 hav I out of the. end of the sound ing a hub 34 mounted eccentrically on a pivot 35 attached to the base 12 of the tone arm 13, as plainly illustratedinthe drawings: The other arm- 36 of the'bell crank lever 33 is adapted to-engage the under side of a pin 37 projecting from the'base 12 of the tone arm 13. Normally the arm 36 1s a distance below the pin 37 but when a swinging movementis given to the bell crank lever 26 in the direction tone arm 13' upward on further movement of the hell crank lever 20 in the direction of the arrow we thattlie stylus 15 is lifted groove of the record 16 and-further movement of the lever 20' in the direction of the arrow :0 causes edeof the tone arm n 13 to swing outward to start in position,

The hub-34 rides on the upper a segmental plate 38 held vertically ad ustable on the bearingll by screws 39 extending through {vertical slots '-40 in the plate 38, the screws 39 screwing in the hear ing 11, B the arrangement described the ever 33 always returns toprop'er ever 20 have returned to normal position;

The underside of'the-cam end of the cam lever '20 is engaged by a pin mounted to slide up and down in the frame 10 resting on the freeend of an armature lever 51 of a pair of electromagnets 52'connected with .a battery or other source of electrical energy purpose use is made ;tone arm 13 adapted to -53. Normally the electromagnets 152 are deenergized and-the armature lever 51 is in the position shown in Fig. 3-, but when the electromagnets'52 are energized then"the armature lever 51 is attracted'an 50.

the pin 50 is .raised whereby an upward swinging movcmentiis given to the -reaiend of the cam lever 20 so that the forward end 24 moves into the'path of the rollers 25', as previously explained. The electromagnets 52 are controlled i 'rom'the tonefajrm 13 and for this arranged as folloits:

The circuit wires 54 and 55 for the circuit of screw 67 screwing screw 67 1S coiled which bears on the the electromagnets 52 connect with the bearing 11 and consequently with the base 12 of the tone arm 13 and with the pin 67 to close the electric circuit whenever the arm 61 engages the spring contact 62. When the tone arm 13 shown in Fi 2, then the contact arm .61 is a distance rom the contact spring 62 but when the stylus reaches t'he inner end of the sound groove on therecord 16 the arm 61 moves in engage ment with the'contact spring 62thus closing the circuit for the electromagnets 52 to energize the latter. slide 63 can be adjusted to move the contact spring 62 nearer to or farther from the contact arm 61 thus allowing adjustment for records of different sizes, it being understood that in using the repeating device the user engages the stylus with the end of the sound slide 63 so that the spring 62-is in contact with the arm 61.

When the stylus reaches the end of the soundgroove with the spring, contact 62 to close the circuit with a view to energize the electroinugnets 5" The out.- ward swinging movcuwnt of, 13 is preferably limited by a 6;1'70 at the end of a slide 71 mounted to slide in hearings 72 attached to the frame 10; The slide 1 is provided with a slot 72 through which coiled a spring" 5 bearing-on the slide 7l so latter in adjusted position.

When this takes place the cum lever 20 is returned immediately to its normal position by the prior to the the free end 24 of the cam lever the spring 23 bears down on the rear end. of

the cam lever 20 so as to hold the latter normolly in inactive position, as shown in Figs;

The operation is as-follows': Y the record 16 has been placed in P0- sitgenonthe platform'17 then the operator:

c tone arm us-tohold the It will benoticed that the 1 The tone arm 13 is then swung outward and the stylus 15 engaged the cam lever 20 is secured a plate 8O,

It is understood. that Figl l and remain so until'the stylus reaches a the inner end of thesou'ndgroove, and when swings the tone arm 13 inward: until the stylus 15 is at the inner end or the sound groove of the record 16. The operator now adjusts theslide 63 so as to engage the contact spring62 with the contact arm-61. The tone arm 13 isetheu swungoutward by the operator until the stylus is at the beginning end of'the soundoove, and the operator now adjusts the'slide 711so that the stop 60 is'in engagement with the-contact arm% 61; The several v arts of the repeatin device are now in. t e inactive position's'lown' in this takes place the contact. arm 61. makes contact with the contact spring 62 to close the circuit for the electromagnets 52; The

armature-5L is :now attracted thus rais'irig'the pin 50 and with it the rear end of the cam lever 20 to swing the front end 24' thereof intof'the path of'the-next oncoming friction roll'er25. This friction roller 25in engaging: the end24 imparts a; swinging; motion to the cam lever 20 in the direction of the arrow m so that the step. 31 of the cam 30 engages the arm 32 of the bell crank lever 33and" imparts a short swinging motion to the same-until the arm 36" engages the: pin

after which thetone arm-13 is swung.- upward by the further movement" of the camleve'r 20in the direotion of the arrow Thus'the stylus. is lifted. out" of the sound groove and further movement of the cam lever 20 in the dire'ction of the-arrow w .causes' thebelhcrank lever to bodily swing the tonearm 13 outward'until the arm 61 abutsa'gainstthe stop '70; It is'und'er'st'ood that when the tone arm 13 begins-to swing outwardthe contaet between the a'rm 61- and theuspring 62 is broken thus breakin'g'the electric circuit" for the electromagnets 52" for the latter toarelease the-armature lever 51'. The pin 50 now returns to" lowermost positionand the bell crank lever"20 is returned to itsn'ormal positionby the action of its spring: 23- as soon as the acting: friction mum- 25 leaves-the end 4m ns; bell'orarik,
