. Be itknown that I, GUsrAvE Meuse, a. citi'ien of the yUnited States, residing at Chicago, inthe county of Cook and State o llli'nois, have invented certain new and usefnl Improvements p in Gramophones, of which .the followin is a specification.V

This invention r ates, to machines for regrph ones or the like, and particuoperating such devices, so that they may be opent .the orjtxme which is produced as many times as may be desire g The objects of rn invention are to' provide a simple and cientperatingmeehenism for gramophones means for causing said gramophone to repeat one or l phone to repeat a ortiorr of the piece being produced; means or causing it to stop alito- 'means for causing it'- to repeat :internati-Q cally; and in genera-l' to provide such' novel' featuresand improvements as win appear -1 hereinafter. Y

In' the accoriipanying drawings illustrating my invention, Figure 1 is: e side view of a gramophone embodying the' same, the side of the box or easing being' removed' and parts heilig broken away or shownda' grammatiewlly for convenience in the illiisi Eineipal operating mechanism, parts also ing omitted or shown diagrmmatleally; Fig. 3 is a plan view showing certain details of construction; Fig. 4 is an' enlarged detail! for controlling 'the eur-rent to' the magnet.; f Figs. 5 and 65ste enlarged details of the screw and nui', used #orf returning the reproduoer device to starting or other' desired" position. I

vAs illustrated in these-drawings, I have' showed my invention asspplied to a gramo- 1 phone having' a swinging* arm mounted' on aE universal joint .whic -permits the reeord' groove to move-the styles across the' face of the record, such form of instrument being' in, common and1r welll known use, h' certain features thereof may be utilized' ini-' other forms of instruments. In accorne with these drawings, 8 indicates only suitable casing' or frame work for' the various parts,

may be driven iny any-desired manner', for instance 'by means of a shaft 10', which has. a worm gea-r 11 thereon, this gear' being driven by a Worin 12 on the driving mat o! a motor 13. The swinging arm-14 lis i for receiving the disk more 1o. 'riss plamounted on 'av pivot or pin 15', having' its endsV fitting in' a groove 16 in a circular basel'Z, so as to provlde a substantially universal joint.. At the oppositeend of the swing'- ing arm 14 'is the sound reproducing defv vices.,y which for convenience will he' called the head 18. This head is arranged in proper position over the disk 10,. so that the .arm may swing,I horizontally as the head moves across the record portion of' the disk l under the influence' of the sty-lus The prin-- cipal feature of my invention as illustrated :in: this preferred form, consists in providingmeans for swinging' the arm 14 to raise the head 18, then to swing the arm horizonf tatly in order to bring the head back to the desired position for repaiucinzgf all or a 'portion ofthe record. To' this end, I pivot g a vertical shat or arm 19 .on the vloer-icons` tai pin or pivot 15, so that said arm is free to swing within certain limits in a vertical plane, but rotates with the arm 14 when said arm is' swung in. a horizontal plane.

At the upper end of the shaft 19' is a foot .orprog'ectiome 20, which is adaptedl to engage' with a lug-Q1 in the tributari' arm 14', the ar-V rangement being such that whenthe lower end of the shaft 19 is swung inwardly, the projection 2t) .will strike against .the lug `21 and mise the outer or free end' of the arm- 14 so as to raise the head 18 out o engagememt with the disk. When the. lower-.end

'.oi the shaft 19 again swings to the ri vt it will free the arm' 14 so that the styus 4may aga-in engage with the 'elissnv It will.4

also be observed that the-arm 14 may 'be swung upward'y hy hand 'Without disturb ing the shaft 1 v. This shaft however, must `alwmtys rotate with the arm 14 when arm is swinging in a horizontal plane. Ity Wild therefore, be seen that h properly manipulating'the lower Iend of 4per-doomed hy means ofthe oll'owingdevices. At the' lower of the' shaft 19 -shaft 19 the armv le may he raised to raise the head 18 away issn" 22' eivotallymounted on said shaft and guided to prevent rotationby means of a forked or slotted bearing 23. At the opposite or free end of this arm 22, is an armature 24, which is acted upon by means of an electromagnet 25, this electromagnet being supported in any convenient manner, as by means of a bracket 26 from the box or casing 8. When there is no current passing through the magnet 25, the armature 24 will be freed, which will allow the shaft 19 to swing to the right under the influence of the weight of the arm 14, thereby permitting the arm 14 to swing down until the stylus comes in contact with the disk. When a current is passed through the magnet 25, the armature 24 will be attracted which will swing the shaft 19 to the left, thereby swinging the arm 14 upwardly until the stylus is raised away from the record disk 10. j

In order to rotate the shaft 18 so as to swing the arm 14 in a horizontal plane, I provide said shaft with a second arm 27, the free end of which is adapted to engage with ,a threaded member or half-nut 28.

' This half-nut 28 is adapted to engage at times with a screw 29, while at other vtimes it is free therefrom, This screw is mounted in suitable bearings 30 from the main frame and isfconstantly driven, while the machine is in operation, by the motor 13. The motoris provided witha pulley 31 from which a belt 32 runs to a pulley 33 on the end of the worm 29. In order that the half-nut 28 may swing down out of engaffement with the worm 29, it is provided with which is pivoted on a rod 35, which extends substantially the full length of the screw 29,y

such arran ement being. clearly shown in Figs. 5 an 6. This half-nut or threaded member 28 is also provided with 'down-y wardly extending projections or fingers-36 yon either side vof the arm 27, the inner faces of these projections being arranged so that they will not bind the arm as the nut travels along the screw. This arrangement is such that, when the arm 7 is swung upwardly, which is done by the magnet 25, its o-uter end, which is in constantengagement with the threaded member 28 will raise this member into engagement with the screw 29, which screw then causes the nut to move longitudinally thereof, sliding along on the rod nections andswltches which will now be de' scribed. The shaft 19is provided with a third arm which may bevdesignated awiper arm'- 3,7 having an upwardly extending sprincontact finger 38 and alhorizontally exten ng finger 3 9. A bearing 40 from the an arm 34 main frame supports a tubular contact mem-l ber 41 arranged transversely to the arm 37. This tubular member carries an adjustable sleeve 42 having a downwardly extending contact arm 43 with which the contact finger 39 is adapted at times to make connection. An upwardly extending aim 44 from the sleeve 42 passes through a slot 45 in the top of the casing, and provides means whereby the sleeve is prevented from rotating and is also readily adjusted.

A rod 46 passes through the tube 41 and has an extension 47 atone end of substantially the same outer diameter as the tube. At the opposite end of the rod is a spi-ing 48 tending to hold the rod with its end 47 pressed against the end of theA tube 41. 'The extension 47 is provided with a projection 49 of insulating material, which projection is adapted to open a double pole switch 50 when the rod 46 is moved to the left as indicated in Fig. 4. The projection 47 is provided with a horizontal pin 51 which is,v

adapted to be engaged at times by a pin 52- -projecting at right angles from a shaft 53 Ifront thereof where it is provided with an arm 54 by means of whichl'it may be ro- 'tated. Stops 55 and 56 are provided for .the arm 54 to limit its movement. The op# eration of this. portion of m invention will be most readily understo .cont-act occurs at substantially the same time that the piece is finished. This contact closes a circuit through the'magnet 25, thereby causing the shaft 19 to be-swunA inwardly and simultaneously raising the .ree end of thewiper arm 37 This causes Ithe` contact finger 38,110 make contact with the tube 41 so as tokeep the circuit closed -through the magnet 25 whilevthe screw 29 4causes the shaft '19 to rotate, which also 'causes thel wiper arm 37-to swing to the left as'indicated in Fig. 4. When it is `desired to 'have the piece repeated, this contact arm moves to the left until the finger 38 passes beyond the end of the extension 47 Vwhen the circuit through the magnet will be broken and the arm 14 will bey permittedto swing Idown so that the stylus 'again comes in contact with the record and the piece is againr played., lIt will be noted thatA this action will keep .on indefinitely, the piece bein repeated: as many times as desiredor'unti the-machine is finally stopped. However, if

it is ldesired to cause the machine to stop after the piecehas been played, the operator 'turns the 'arm 54 up until it engages the from Fig. v4. v `When the'wiper arm`37 moves toward the right,'as it will be when it follows the nor.-`

Stop 55 which swingsthe pin '52 up against the .pin 51 and brings the pin 52 within the path of the wiper arm 37, so that the arm strikes this pin before the contact finger 38 A with the wiper arm 37.

passes off from the end of the extension 47. When the arm 37 strikes the pin 52the latter will press against the pin 51 `and thereby move the rod 46 to the left until the Aproject-ion 49 strikes the switch 50 and opens the circuit through the motor and through the magnet, thereby stopping the machine and restoring it to its normal position. This movement of the rod 46 is comparatively slight, so that a slight exibility of the pin 52 and its connections will lpermit such movement even though the arm 54 is in contact with the stop 55. The electric connections may be arranged in any convenient manner to accomplish the purpose above set forth. For instance the battery 57 is pro vided with wire 58 leading to the pole 59 of the double switch 50. Another wire 60 leads from the other terminal of this switch and is connected with the rod 46 or some of the parts in contact therewith, these parts being insulated from the remainder of the machine. Another \vire 61 leads from the battery 57 'to one of the terminals of the magnet 25, and the other terminal of this magnet is connected by means of a wire 62 This will permit the necessary circuits to be made to operate the magnet as above set forth.

The motor 13 may be driven from the same source o f electricity asused for controlling the magnet, but is preferably driven by means of acurrent from an electric light or power service system. vIn this case one wire G3 leads to one terminal of the motor while another wire (34 leads from the other terminal to one of the poles of the switch 50, the third wire G5 leading from thence to the source of electricity.

In some instances it may be desirable to stop the instrument before it completes the piece it is reproducing, and cause it to repeat the portion it has already reproduced. In order to do this, I provide a wire 66 leading from the wiper arm 37, or the terminal of the magnet which is connected with said wiper arm, to an open key 67. Another wire (S8 leads from said key to the rod 46 and its connected parts so that when this key is closed, a circuit is completed from the batteries through the magnet,-thereby causing the magnet to operate and attract the armature 24 which raises the head of the instrument and permits the screw 29 to swing the instrument back to initial position in the manner above specified, the contact linger'38 maintaining the contact so that the key 67 does not need to be held closed.

It will be observed that various changes may be made in my invention' to accommo date the same to different forms of gramophones or similar devices and, I, therefore,

do not wish to be limited to the particular form o-r arrangement of apparatus herelnbefore described, further than pointed out in 1 l varm and adapted to actuate the same, an

electro-magnetic device for swinging said shaft to raise the reproducer away from the record, means coacting Witlrsaid shaft for rotating the .same 1to suing .thel reproducer back or toward its starting position, which means is actuated when the shaft is swung by the magnetic device, a source of electricA ity for lsaid electro-magnetic device, and circuits and contacts arranged so lthat the current supplied to said device will be automatically stopped when the reproducer returns to intial position, but may be controlled or regulated by the operator after the reproducer has moved forward from its initial position. l
