Referring to the drawings, the phonograph comprises a motor board H) on the under side The bracket ll provides a suitable support for a turntable spindle I2 which projects upwardly through the the motor board l0. On the upper side of the motor board the spindle l2 has mounted thereon a turntable IS. The spindle I2 is connected to the turntable l3 so that they both rotate together.

The lower portion of the spindle l2 has rigidly mounted thereon a pinion H which is adapted to mesh with the peripheral teeth on a mutilated gear is. The mutilated gear is mounted for free rotation upon a shaft I 6 carried between the bracket II and the motor board Ill.

Below its teeth, the pinion I4 carries a plurality of large teeth II which project outwardly in the radial direction. As will hereinafter be explained, the gear I5 is given two movements constituting one complete revolution between the playing of records. During the playing of a record, a gap I8 in the peripheral teeth of the gear I5 is opposite thepinion l4 so that the gear I5 is at rest during the playing of a record. At this time a detent I9 is forced by a spring 20 into a small recess 2| on a flange of the gear 15 above its teeth so that the gear is held against displacement due to vibration or other accidental causes.

. The phonograph is actuated by means of an electric motor 22 which has a small driving wheel 23 located on the upper side of the motor board In. An idler 24 is adapted to engage the driving wheel 23 and the inner side of the flange 25 of the turntable l3. The idler 24 is mounted on an arm 26 ,pivotally mounted on the motor board at 21. A spring 28connected to the arm 26 and to the motor board l0 biasses the idler 24 towards engagement with the driving wheel 23 and th flange 25.

The idler 24 is preferably provided with a tire and flange so that t ere is no possibility of fiat surfaces being produced on the tire 29.

The arm 26 rigidly carries an extension 30 which is connected by a tension rod 3I to one end of a lever 32 pivotally mounted on the upper side of the motor board on stud 33. This end of the lever 32 has a surface '34 adapted to be engaged by a tooth 35 of a pawl 36. The pawl 36 is pivotally mounted on the upper surface of the motor board II) by means of a stud 31.

The pawl 36 rigidly carries an arm 38 having a braking member 39 which is adapted to engage the inner side of the flange 25 of the turntable I3. The arm 38 is preferably adjustably mounted on the pawl 36 so that correct adjustment of the braking member may readily be made.

The aforesaid end of the lever 32 and the pawl 36 are biassed towards each other by means of a spring 40. This spring biasses the pawl 36 so that the braking member 39 tends to engage the turntable, and the spring also biasses the rod 3I towards the idler 24 so that the idler may be engaged with the wheel 23 and the flange 25 by the spring 28.

When the tooth 35 is in engagement with the surface 34, the braking member 39 is in engagement with the flange 25 and the idler 24 is held away from the wheel 23 and flange 25, as shown in Fig. 7. When, however, the pawl 36 is swung in clockwise direction as viewed from above, the tooth 35 is swung away from the surface 34 and the combined action of the springs 40 and 28 effects engagement of the idler 24 with the wheel 23 and flange 25, as shown in Fig. 9.

When the phonograph is not operating, the braking member 39 is forced against the flange 25 of the turntable by the spring 46, as shown in Fig. 7, and the lever 32 has its surface 34 bearing against the tooth 35 of the pawl 36 in a substantially radial direction by the same spring 40. In this position of the lever 32, the rod 3| holds the idler 29 clear of both the flange 25 and the driving wheel 23. instead of the common spring 40, two separate springs may be provided for the pawl 36 and the lever 32 so as to bias them in the same efiective directions as does the spring 46.

The player arm 43 is connected by a horizontal pivot 44 adjacent its rear end to an arm 45 whichv is rigidly mounted on the upper end of a vertical sleeve 46. The sleeve 46 is pivotally mounted on a pedestal 41 so as to provide for the free translational movement of the player arm over the record.

A rod 48 is located in the sleeve 46 for free vertical movement. The upper end of the rod 48 is adapted to engage the under side of the player arm 43 at a position slightly forward of the pivot 44. It will readily be understood that when the rod 46 is moved upwardly, the player arm 43 is elevated from its normal substantially horizontal position.

The lower end of the rod 48 rides on a cam 49 formed on the upper side of the gear l5. The cam 49 is provided with a cam rise 53 which raises the pin 48 immediately after the playing of a record, and a cam fall 56 which permits the pin 48 to move downwardly again at the proper time to bring the player arm needle into engagement with the record.

On the lower end of the sleeve 46 is rigidly mounted a horizontal arm 5I which carries at its outer end a pin 52 which projects both upwardly and downwardly from the arm 5 I. The lower end of the pin 52 rides in a cam track 53 formed in It will of course be understood that the upper surface of the cam wheel I5. During the playing, the pin 52 is clear of the inner cam member 54 which defines one side of the track 53 so that the player arm is free to move inwardly during playing of the record, as shown in'Fig. 8.

After the playing of the record, the cam wheel I5 starts to rotate in the counter-clockwise direction as viewed from above, from its position in Fig. 8, and the pin 52 is engaged by a cam rise 55 on the inner cam member 54 so that the pin 52 is moved outwardly and consequently the player arm is thrown outwardly clear of the record. The player arm remains in its outward position during the time that the pin 52 is located in the cam track 53.

When the pin 52 is thus thrown out, its upper end engages an arm 56 which is pivotally mounted by means of a stud 51 on the under side of the motor board I0 so that this arm is likewise thrown out into its position in Fig. 6 against the tension of a spring 58 connected to thearm 56 and to the under side of the motor board.

It may here be noted that the motor is stopped when the pin 52 is still in the cam track 53 as shown in Fig. 6. When the motor is again started, the gear I5 resumes its motion in the coun-,

ter-clockwise direction a viewed from above, and the pin 52 rides inwardly against a cam fall 53 on the cam formation'54 and consequently the spring 58 swings the arm 56 inwardly, carrying with it the pin 52 and the player arm 43. This inward movement is suflicient to bring the player arm into a position above its initial playing posireadily be understood that the arrestment of the When the pin 52 rides inwardly over the cam I fall 59, the pin moves the arcuate arm 64 inwardly against the tension of its spring 65, the spring 58 being much stronger than the spring 65. The spring 65 is, however, sufliciently' strong to hold the spring 63 compressed after the arm 56 is arrested by the projection 60. While the pin 52 is still' engaged by the arcuate arm 64 the player arm moves downwardly so as to bring the needle into engagement with the record; I When the arm 64 clears the pin 52, the spring 63 moves the pin 52 inwardly to a very slight extent, so as to bring the needle into the first groove of the record. Thereafter, the'gear I5 is arrested,

leaving the pin-52 free to move inwardly with the otally mounted-in a radial slot 61 which slot is located adjacent the' gapjil. The upwardly extending arm of the lever 68 is normally, that is, during playing of a record, engaged by a latch member 68 so that the horizontal arm of the lever 66 is held at a position above the large teeth i1 1 on the pinion 14. v

When the latch member 88 is moved away from the vertical arm of the lever 48, the lever 66 swings downwardly, bringin the outer end of its major portion into. alignment with the teeth 11. Engagement of the end of the lever 66 by the teeth l1 moves the gear 16 around sufliciently to bring the peripheral teeth of the gear in mesh with the pinion l4.

The latch 69 is pivotally mounted on the upper side of the gear l5 and is biased towards latching position by a spring 10. Means are provided for relatchlng the bell crank lever 86 during the single rotation of the gear i5. This means may suitably comprise an oblique flange 1| on the under side of the horizontal arm 5|. It will be understood that during each revolution of the gear IS, the upwardly directedarm of the lever 661s engaged by the flange 1| and is moved inwardly, thereby bringing the lever 66 into normal position in which it is again latched by the latch 69. The latch 69 is released automatically by the player arm 43 at the end of the playing of a record. The arm 5| has a serrated edge 12 which is adapted, near the end of the playing of a record, to engage a dog 13 pivotally mounted on the latch member 69. The serrated. edge 12- is adapted to slip past the dog 13 which is biassed I into a definite position by a spring 14.

When, however, a reverse movement is applied to the player arm 43, for example as the result of an eccentric end groove on the record, the serrated edge 12 cents the dog 13 and displaces the latch member 69 so that the lever 66 is released and the drive of the gear I5 is initiated.

The arm 5| also carries an abutment member 15 which is adapted to engage an abutment member 16 on the lever 69 and effect swinging movement of the latch member 69 as the result of the player arm moving inwardly to a sumcient extent upon the record. Thus, all moderntypes of records will control the trip mechanism and initiate the drive of the wheel I5.

The embodiment of the invention illustrated is provided with a single manual control and in its operation it is necessary merely to apply a rec- 0rd to the turntable and actuate this single manual control. The player arm then moves inwardly automatically, engages the record, and plays it, and after the playing of the record, the player arm rises and moves out clear of the record, whereupon the single control member is returned to initial position and the mechanism stops. It is then necessary to replace the record and again actuate the single control member.

In the present embodiment of the invention, the single control member is a button 11 which is located on the upper side of the motor board and is mounted through a slot" upon a bar 19 slidably mounted by means of studs and washers oil"' and is in its intermediate position. a pin 83 is located within the apex of the V formation formed by the two cam members 82. This pin 83 is rigidly mounted upon the pawl 36 and projects downwardly through a suitable opening in the motor board into cooperative relation with the cam members 82.

It will readily be understood that when the bar 19 is displaced by the button 11 from its normal or intermediate position, the pin 83 is moved inwardly, that is, towards the center of the turn.- table from its position in Fig. '7. Consequently, the pawl 36 is moved inwardly to withdraw the braking member 39 from the flange 26 of the turntable i3. Continued movement of the bar 19 moves tooth 35 of the pawl 36 away from the surface 34, and the spring 40, or the individual spring of the lever 32, swings this lever in the counter-clockwise direction as viewed from above, about its pivot 33, thus permitting the spring 28 to move the idler 24 into contact with the driving wheel 23 and the flange 26 of the turntable l3. When the button 11 is displaced from its normal position to full extent, the pin 83 is locatedon flat surfaces 84 at the extremities of the cam members 82.

The bar 19 is biassed towards its intermediate or ofi position by means of a suitable spring. This spring may, for example, be a leaf spring 85, which may, if desired, be associated with a switch assembly 86. The spring 85 is adapted to cooperate with two adjacent pins 81 carried by the bar 19. It will be understood that when the bar 19 is displaced from its normal position in either direction, the spring 85 bearing against one of the pins 81, tends to return the bar to its normal position. It will of course 'be understood that any other desired type of spring may be employed for this purpose.

When the bar 19 is displaced to its full extent in either direction, it is held in such displaced position by means of a pin 88 which is adapted to enter one or other of the two recesses 83 located in one side of thebar 18. The pin 88 is mounted on a bell crank lever 90 which is pivotally mounted at 9| upon the under side of the motor board ID. This bell crank lever is biassed by a spring 92 so that the pin 88 bears against the bar 19 and is adapted to enter the recess 88 which is presented to it by movement of the bar 19 in one direction or in the opposite direction. The recesses 89 are so conformed that the bar I! is effectively held thereby until the pin 88 is again automatically withdrawn from the recess.

One end of the bell crank lever 90 carries a pin 93 which projects upwardly through a slot 94 in the motor board iii. The other end of the bell crank lever carries an oblique flange which projects downwardly into operative relation with a peripheral cam formation Won the gear IS.

The flange 95 is engaged, by the cam formation 96 duringthe rotation ofthe gear IS with the result that the pin 88 is withdrawn from the recess 89 'in which it is located, thus freeing the bar 19 so that it is returned to its normal position by the spring 85. The movement of this bar actuates the switch assembly 86 inthe manner which will hereinafter be described so that the motor stops. p

The return of the bar 1.8 to normal position, permits the pin 83 to return to its positionin the V formation between the cam members 82 under the influence of the spring 40 so that the brake oi the spring 48.

is applied to the turn-table. The actuation of the flange 85 by the cam formation 88 also throws the pin 83 towards the lever 32 so that this lever is positively swung so as to pull on the rod 3| and remove the idler 24 from the flange 25 and the driving wheel 23.

The cam formation 96 is suillclently short to enable it to clear the flange 86 before the movement of the gear I5 is stopped. Consequently, the pin 83 is retracted from the lever 32 and this lever 32 tends to rotate in counter-clockwise direction as viewed from above, under the influence This movement, however, brings the surface 34 of the lever 32 into engagement with the tooth 35 of the pawl 36 and the idler 24 is held clear of the wheel 23 and the flange 25, as shown in Fig. 'l.

The switch structure 86 comprises two switches 31 connected in parallel in the circuit of the motor. Both switches are normally open. When, however, the bar 19 is displaced in one direction, one switch is closed, and when it is displaced in the other direction, the other switch is closed. It will, of course, be understood that any equivalent switch mechanism controlled by the bar 19, or an associated element, may be employed, if desired. In the switch illustrated, both switches 91 are constituted by leaves. The spring 35 is assembled between these switches and is adapted to actuate adjacent leaves by means of blocks 98 of suitable insulating material. It will readily be understood that when the spring 85 returns the bar 19 to its normal position, both switches 19 are opened.

The switches 19 are both arranged for late closing; that is, the switches 19 do not close until the pin as is almost on the point of dropping into one or other of the-recesses 89. Consequently, when the bar 19 displaced-from normal position. the pawl 36 is moved'outwardly to remove the braking member 39 out of contact with the flange and the idler 24 engages the driving wheel 23 and the flange 25 before the pin 88 enters one of the recesses 89 and before the corresponding switch '|9 becomes closed. This condition, which is illustrated in Fig. 10, prevents the idler 24 from bein moved into contact with the driving wheel 23 hen the latter is being driven at a high speed.

The operation is as follows:

When the phonograph is out of operation, the brake 39 is hearing against the flange 25, the idler 24 is clear of the flange 25iand the driving wheel 23, the player arm 43 is clear of the tumtable and is elevated, the pin 48 resting upon the elevated portion of the cam 49,-the cam formation 96 is clear of the flange 95 so that the pin 93 is clear of the lever 32, and the button 11 and bar 19 are at the intermediate or off" position, both switches 19 being open.

To put the machine into operation, it is necessary to place a record upon the turntable. The button I1 is then moved to its operating position corresponding to the record to be played. If the .record is a ten-inch record, the button 11 is 83 and swings the pawl 36 inwardly towards the center of the turntable, removing the brake 39 from the turntable and removing the tooth out 'of contact with the face 34 of the lever ,32.

The spring 48 moves the lever 32 in counterclockwise direction as viewed from above, and moves the rod 3| towards the idler 24. The idler is caused to contact the wheel 23 and the flange 25 of the turntable. The pin 38 becomes located on one of the surfaces 84 and the bar I8 is locked in its displaced position by the entry of the pin 88 into one or other of the recesses 89, depending upon the direction in which the bar 18 was moved. The flnal part of the movement of the bar 18 closes the corresponding switch 91.

The operation of the motor through the wheel 23 and idler 24 drives the-turntable. The gear I5 is initially in its position of Figs. 4 and 6 and is in mesh with the pinion H which is driven by the turntable and consequently the gear I5 is driven immediately the motor is put into operation. The arm 56 is in its outermost position since the pin 52 is in the cam track 53. The rotation of the gear I5 brings the fall 59 of the cam 54 past the pin 52 so that the spring 40 moves the player arm inwardly.

During its inward movement, the pin 52 engages the arcuate arm 64 but the strong spring 58 moves the arm 64 inwardly until its surface 6| or surface 62 engages the projection 66, thus locating the player arm in elevated condition above the initial playing position for the size of record on the turntable. The fall 58' of the cam 49 now passes below the pin 48, with the result that the player arm is caused to drop downwardly to bring its needle into engagement with the record. Thereafter the arcuate arm 64 clears the pin 52 and the spring 63 gently moves the player arm inwardly to a slight extent so as to cause the needle to enter the first groove of the record.

During the rotation of the gear IS, the upwardly directed arm of the lever 66 has been the pinion H, the drive of the cam I5 is terminated. At this time the detent l9 enters the recess 2| in the gear l5 so that the gear is held immovable until the drive of the gear is again initiated.

The record is now played, the player arm mov ing in gradually over the surface of the record. At the end of the playing, the latch 69 is released by the action of the serrated member I2 and the dog I3 or by the action of the abutment member 15 and the abutment member 16. The horizontal portion of the lever 66 now drops into the path of the large teeth I1, with the result that the gear I5 is moved to a slight extent and is brought into mesh with the pinion l4.

The rise 50 of the cam 49 now passes below the pin 48 so that the player arm 43 is elevated. The pin 52 is then engaged by rise 55 of the cam 54 and swung outwardly, carrying the player arm outwardly, clear of the record, and carrying the arm 56 outwardly against the tension of the spring 58. The cam formation 96 now rides over the flange 95 on the bell crank lever 90, swinging this lever against the action of the spring 92.

The movement of the lever 98 carries the pin 93 into engagement with the lever 32 so that the idler 24 is pulled by the rod 3| away from flange 25 and driving wheel 23. The movement of the lever 20 withdraws the pin 88 from the recess 89 in which it was located, so that the spring moves the bar 18 into its intermediate position.

assays opening that switch I! which was closed, and terminating the drive 01' the motor. a

The return 01' the bar I! to its intermediate position, enables the spring to retum the braking element 3! into contact with the flange 25. At this time the cam formation Si clears the flange 85 so that the lever 9! is swung by the spring 92 until the pin 88 engages the side of the bar 19 between the two recesses 89. The movement of the pin 93 away from the lever 3! enables the spring III to move this lever to bring the surface 34 into engagement with the tooth 35 of the pawl 36, as shown in Fig. 7. This relation maintains the idler 2| clear of the driving wheel 23 and flange 25 of the turntable. This movement of the lever 9| bringsthe pin 93 clear of the lever 32, as shown in Fig. 7, so that this lever is free to move under the influence oi the spring 40 just as soon as the bar I9 is moved sumciently in one direction or the other to swing the pawl 36 away from surface 34 of the lever 82. After the motor and the turntable have stopped and the bar 18 has returned to its intermediate or off position, the machine is again in the position described at the beginning of this description of the operation.
