} TALKING-MACHINE.

v Appl ication filed July 10,

Be it known that I, GEORGE H. ISLEYI, a

citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, haveinvented a new and useful Improvement in Talking-Machines, of which the following, together with the accompanying drawings, is a specification.

The present invention relates to improvements in talking machines, and more particularly to such machines as are adapted.

for playing a plurality of records successively, an object of the invention being the provision of automatically operated means for causing the successive reproduction of a plurality of records without the necessity of any attention by an operator.

-The machine of the present invention also contemplates the automatic reproduction,- when desired, of any given record among a plurality of different records carried there-. by. The above and other objects are attained by the introduction of a novel .principle of operation in devices of this class, whereby a construction ofi extreme simplicity is possible, and whereby the expen sive and, complicated mechanisms heretofore employed for accomplishing the above purposes. are eliminated.

The invention is fully set forth in the following description, reference. being had in this connection to the accompanying drawings which illustrate, by way of example merely, one embodiment thereof; it will be clear, however, that'n'umerous modifications of the mechanism there disclosed may be resorted to without departingfrom the spirit of the invention and the novel principles underlying the same, as recited in the annexed claims. In said drawings,

Figure 1 is a plan-view of the mechanism, with certain portions thereof broken away and shown in section, to illustrate more. clearly the construction of other parts.

Fi 2 is a plan view ofa cam carrying mem er forming part of the mechanism shown in Fig. 1. I I

Fig. 3 is a fragmentary view, in elevation, of the member shown in. Fig. 2. V

Fig. 4 is a sectional view, showing a form of rotatable record support, as .used in the mechanism shown in Fig. 1.

Like reference characters refer to like parts in the different figures;

Referring to Fig. 1, the mechanism here Specification of Letters Patent.

shown for purposes of illustration is of a horizontal type, and adapted for operation on the so-called disk records; It is to be understood, however, that the principles of my invention are clearly applicable to other types of talking machines than the horizontal type here illustrated as well as to other kinds of records. The mechanism in. the present instance may be suitably supported and disposed within a casing C, and said mechanism comprises essentially a rotatably mounted wheel or spider 1. The rim of wheel 1 serves for the support of a plurality of record tables 2, the latter being carried on hollow shafts 3 which are journaled at eipal distances around the rim of wheel 1. ach shaft 3 has secured to' its lower end a friction wheel, by which the shaft with its attached recordtable 2 is rotated, ina manner hereinafter described, for the playing of a record disposed on said table. A record is suitably positioned on each. 'table 2 by means of a centering spindle 5,

which projects above the supporting face of table 2 and is slidable through the bore of shaft 3, being heldyieldingly in position by means of a spring 6 encircling and attached to its lower end and also attached to the associated friction Wheel 4.

The record tables 2 are thus arranged in annular or circular form about the center of the revoluble member 1, and preferably, as shown, the shafts 3 are obliquely journaled, so that the tables 2 are slightly inclined, in order that the records, when placed there- ,on, will progressively overlie each other and yet all be approximately in the same general plane. Under these conditions, with recordsof the same size, the peripheral portions of all the records will be at equal distances from the central ortions of adjacent records, and thus the s iftin of the tone arm and reproducing needle om one we 0rd to another, in the manner hereinafter described, will be greatly facilitated.

Concentric to the member 1, and revoluble in unison therewith is a cam supporting member 7, whose rim is adapted to carry the ment, in any desired position to the rim of the member 7. Said cams are arran ed in pairs on said member, the number o pairs 1 corresponding to the numberof disk records carried by the member 1, and obviously said cams are capable of adjustment to any desired position on the member 7, and are also capable of a continuous arrangement, with a single ga Fig. 2, in the event that it is onl desire toplay the particular record wit which the gap is associated, as hereinafter described. Said cams are designed for action upon a swiveled tone arm 10, to raise the same away from the record which has been played and to lower it into operative position with respect to the next record desired to be played, in the manner hereinafter described. Said tone arm 10 is swiveled to a pivoted tubular member 17 in the manner common to devices of this class, the member 17 being in communication with the horn tube of the mechanism, not shown. The tone arm 10 and pivoted tubular member 17 are completely insulated from the members 1 and 7 by means of a suitable insulating ring 11.

For rotating the members 1 and 7 about the common center thereof, a friction wheel 12 is provided, with its periphery in contact with the rim of member 1. The shaft of wheel 12 is suitably Sgeared, as shown, to a prime mover, such as amotor 13, one terminal of which is connected to a brush or wiper 14 by means of a conductor 15. The brush 14 is in constant contact with the rim of member 1, and thus an electrical connection is established between all of the cams 8, 9 and 8, 9' and the motor 13, through the members 7 and 1, brush 14 and conductor 15. When a contact 16 on tone arm 10 engages any one of the cams 8, 9 or 8, 9, the motor circuit is completed, through tone arm 10, pivoted tubular member 17, conductor 18, battery or source of electrical supply 19 and conductor 20, the latter being effective upon the closure of a switch 21. Therefore, only when the switch 21 is closed, and when the contact 16 is in engagement with one of the cams on member 7, will the motor 13 operate to rotate the members 1 and 7 and the devices carried thereby; as soon as the contact 16 is moved away from the cam, the rotation of motor 13 ceases, and the members 1 and 7 become stationary.

For driving the tables 2, an endless belt.

22 is here shown in position for frictional engagement with the friction wheels 4, as the latter are successively moved by the rotation of member 1 into contact with said belt. The belt 22 passes around pulleys 23 and 24, the shaft of the latter being driven by suitable gearin from a prime mover such as a motor 25. T e motor 25 is connected to the source of electrical supply 19 by conductors 26 and 27, the latter having interposed therein a switch 28, which is adapted to be openedautomatically, when desired, by the rotation of member 1, as hereinafter described.

The operation of my improved mechanism, as thus far described, is as follows When the motor 25 is started by closure of switch 28, the belt 22, in the position of the parts shown in Fig. 1, will rotate a record 29 which is in position on the particular table 2 which at that time has been moved into operative relation to said belt. Under these conditions, the tonearm 10, as shown, is between adjacent pairs of cams 8, 9 and 8, 9', and is therefore depressed, so that its needle 30 travels continuously in the groove of the record 29, and gradually approaches the center of said record, in the manner ordinarily characterizing the play of disk records. During the play of record 29, the contact 16 is out of engagement with any cams on the member 7, and consequently the member 1 is stationary. The tone arm 10 and needle 30 swing slowly toward the center of record 29, by virtue of the pivotal support of tubular member 17, as is usual in devices of this class, and finally, approximately coincident with the arrival of needle 30 at the inner end of the record groove, the contact 16 is carried into engagment with the cam 9', which has previously been set in the proper position. This contact between the tone arm 10 and the cam 9 completes the electrical circuit for motor 13, which starts the rotation of member 1 in the direction of arrow A. The member 7 rotates in unison therewith, so that the entire structure, including the tone arm 10, is moved as a single member to carry the record 29 out of operative engagement with the belt 22 and to move the friction wheel 4 of record 31 toward said belt.

During this movement the tone arm 10, which lies in contact with the edge of cam 9', is pushed by said edge toward a stationary stop 36; when the tone arm strikes said stop, as shown in Fig. 1, the continued rotation of member 7 causes said tone arm to ride up the inclined edge of cam 9' and thereby to withdraw the needle 30 from the surface of record 29. With the tone arm 10 I 13, so as to stop the rotation of member 1 just as the record 31 is brought into operative relation to the belt 22, so as to be rotated, for playing thereby. Simultaneously, the tone arm 10 is allowed to drop into playing position, with the needle 30.thereof in the outer convolution of the groove in record 31. After the playing of record 31, the above action is automatically repeated for the playing of the next successive record, as will be readily understood. 4

It will be seen that an outstanding feature of the above mechanism is embodied in the automatic movement of the records into and out of playing position with respect to the tone arm. The tone arm, immediately upon the completion of a record, moves with said record as the latter is carried automatically out of playing position, the previous movement 0 the tone arm, while playing, having inaugurated this shifting movement. T herefore, this shifting movement is effective in raising the tone arm from the record which 'has been completed, and in holding said tone arm raised until the next succeeding record has been moved into playing position beneath the tone arm, whereupon the latter is lowered into operative position, simultaneously with the cessation of the shifting movement. It will be understood, further, that with the mechanism above described, the series of records arranged on the tables 2 may be played over and over in succession, or, if desired, the operation of the mechanism may be discontinued automatically after any given record has been played, by providing stops 32 or 32 in position on the member 1, to open the switch 28, thereby stopping the motor 25. Furthermore, the cams 8, 9 and 8', 9 on member 7 may be so arranged as to enable any record onthe tables 2 to be omitted, or said cams may be placed in the positions indicated in Fig. 2, whereby one record on the tables 2 will be played over and over, all the other records being omitted or skipped because the tone arm is held in elevated position while they are passing beneath the same.

It is to be understood that the drawings herein are illustrative merely of one way of carrying out the novel principles of my invention, and that my invention is not confined to the particular arrangement of apparatus therein shown. The arrangement of the driving devices for. rotating and for shifting the records may obviously be varied,

it being clear that variations in the manner of presenting successive records to the play- 4 ing devices, as well as changes in. the types of records used, are within the contemplation of the invention as defined in the appended claims.
