Referring now particularly to Figs. 1 and 2 of the drawings, the invention here illustrated shows end of the element I8 is provided with a flanged portion I9. which in turn is provided with a groove or race for guiding a plurality of ball bearings 20. The ball bearings 20 rotatably support a flanged tubular shaft ZI by engaging the bottom of a flanged portion 22 thereof. The shaft 2| also is movable with the element in a Vertical plane relative to the bracket Il. The tubular portion of shaft 2| extends downwardly through and below the element I8. The shaft 2l is driven by con necting a suitable driving mechanism to the bottom thereof, not shown in the drawings.

Intermediate the ends of the shaft ZI, there is connected thereto a clutch member 2:3 as shown in Fig. 2. As is evident from Fig. 2, the connection of the clutch member 23 to the shaft 2l permits the clutch member 23 to rotate with the shaft 2| and move relative thereto longitudinally along its axis. Normally the clutch member 23 is in the position shown in Fig. 2.

Immediately above the clutch member 23, a clutch member 24 is mounted on the shaft 2I in such a manner that it does not rotate with the shaft ZI except when it is in engagement with the clutch member 23. The hub portion of the clutch 24 is provided with a Worm gear 25 and is in driving engagement with the gear 26 (Fig. 11) fixed to the shaft 27. The shaft 21 is rotatably supportedby the brackets 28 and 28A which are fixed to the bracket I'I in a suitable manner, as shown in Fig. 2.

The mechanism for moving the clutch member 23 into engagement with the clutch member 24, is best illustrated in Fig. 2 and includes a lever 29 pivotally mounted on bracket 28A (Fig. 2). The free end 2SA of the lever 29 shuts the clutch member 2.3.. Intermediate the ends of the lever 23, there is connected a core 3b having an upper nonmagnetic portion 32A and a lower magnetic portion .3U-B. The coilS l, supported on extension 28B of the bracket 28A, surrounds the core Sil, as shown in Fig. 2, and is adapted to be energized through the conductors 32 and 33 by a tripping mechanism such as that disclosed in U. S. Patent No, 2,018,881. When the coil 3I is not energized, the core 30, the lever 29 and the clutch member 23,. are in the position shown in Fig. 2. When the coil 3I is energized, it acts electromagnetically on portion 3GB whereby the core 3) is moved upwardly to move therewith the lever 29. The upward movement of the lever 29 is sufficient to move the clutch member 23 into operative engagement with the clutch member 2li.

A. turntable 34 is fixed to the flanged portion 22 at the upper end of the shaft 2|, as shown in Fig. 2, to rotate about the axis of the shaft 2l and to move longitudinally along the axis when the element I8 is moved in a corresponding direction. A stack of records 35 are supported on the turntable 34 and are maintained in a centered position on the turntable by a centering pin 3B. This pin extends downwardly through the center of the turntable and the shaft 2l and is suitably fixed in a manner, not shown in the drawings, to be maintained in the position shown in Fig. 2.

Fig.

Turntable elevating mechanism.

The mechanism for elevating the turntable 35i is best illustrated in Figs. 2, 4 and 1() and includes the element I8 which supports the shaft 2| and the turntable 35. At the lower end of the element I8 there is provided a toothed 31 which is in continual engagement with a threaded portion 38 of a worm gear 39. The worm gear 39 is fixed to one end of a shaft 42 to rotate therewith. Intermedateits ends the shaft l2 is supported by a bracket 4I to rotate relative thereto, rpreferably in the manner shown in Fig. 2. At the lower end of the shaft 42 there is afxed thereto a miter gear 43 which is adapted to be engaged and driven by a similar miter gear 4d which is fixed to a short tubular shaft 45. The shaft 45 is supported on the shaft 21 in such a manner as to maintain the miter gears d3 and 44 in continual engagement with each other. The shaft 45 normally does not rotate with the shaft 21` The shaft 55 also has affixed thereto a clutch member 59 (Fig. 2) The clutch member 49 is adapted to be engaged by a clutch member 55, which is operatively associated withthe shaft 21 to rotate therewith and slide thereon. The clutch member 55 has a groove 5i formed in the hub portion of this member.

The member 55 serves to transmit rotary mon tion to the member 59. The mechanism for mov ing the member G into driving engagement with the member A9 is best illustrated in Fig. 10. This mechanism includes a spring-biased lever 52 which is pivotally mounted at 52A on the bracket H and is biased to the position shown in Fig. l() by a spring 55 connected between post 51A in bracket 4I and extension 52B of lever 52. The lever 52 is provided with a nger 55 which is in continual engagement with the groove 5l of the clutch member 5U. The lever 52 also is provided with a pin 55 which is adapted to cooperate with a cam wheel 55 fixed to the shaft 21 to rotate therewith. In the peripheral wall of the cam wheel 55, there is provided a cam groove 51 with an enlarged area 51A. A member 58 is pivotally connected to the cam Wheel 55 in the enlarged area 51A and is provided with heel portions 58A and 58B and a toe 59. The member 58 is connected to the cam wheel 55 in such a manner that it moves only when a positive force is applied thereto. When the lever 52 is in its normal spring-biased position (Fig. 10) and the member 58 is in its dotted-line position shown in Fig. 10, the pin 56 is adapted to be guided by the cam groove 51 during a cycle of operation of the cam wheel 55. When the heel portion 58B engages the pin 55 during this cycle of operation of the cam wheel 55, the member 58 is moved from the dotted-line position to the fullline position shown in Fig. 10. During the succeeding cycle of operation of the cam wheel 55, a toe 59 of the member 58 engages the pin 55 and guides the pin 56 against the tension of the spring 53 from the groove 51 to a position where it is guided by the left wall (Fig. ofthe cam wheel 55. The pin 55 is guided by the left wall of the cam wheel 55 until the enlarged area 51A again permits it to enter the groove 51 under the tension of the spring 53. As the pin 55 is guided from the groove 51, it engages the heel 55A of the member 58 and moves the member 58 from the solidline position to the dotted-line position shown in 10. When the pin 55 is guided from the groove 51 to be guided by the left Wall (Fig. 10), the lever 52 is moved in a clockwise direction (Fig, 10) against the biasing action of the spring 53. This clockwise movement of the lever 52, by means of the finger 54, moves the clutch member 50 into operative engagement with the clutch member L15. With the clutch members 45 and 55 in operative engagement, they are adapted to drive the members L14, G3 and 39 through a cycle of operation. One cycle of operation of the gear 35 raises the member I8 and the turntable 35 a distance corresponding to the thickness of one record.

lt is evident that the mechanism for moving the members 55 and 55 into operative engagement with each other is operative only when the pin 55 is moved from the groove 51 to be guided by the left wall of the cam wheel l55. This occurs during a cycle of operation of the cam wheel 55, at the beginning of which the member 58 is in the full-line position shown in Fig. 10. During a cycle of operation of the cam wheel 55, at the beginning of which the member 58 is in the dotted-line position shown in Fig. 1G, the mechanism for moving the members 55 and 55 into operative engagement with each other does not function. The apparatus is arranged in such a manner that, at the beginning of a record-discarding cycle of operation of the cam wheel 55, the member 53 is in the full-line position shown in Fig. 10 and at the beginning of a record-reversing cycle of operation of the cam wheel 55, the member 58 is in the dotted-line position shown in Fig. 10.

After the last record on the turntable 54 has been removed and the turntable 34 is raised, then it is in its uppermost position. It is necessary to lower the turntable 34 before the phonograph apparatus is ready to play another stack of records. This is accomplished by mechanism illus trated in Figs. 2, 17, 18 and 19 and which includes a shaft 5|. One end of the shaft 6l is supported by the bracket 5I (Fig. 17) and its opposite end is supported by a bracket 62 provided on a portion of the cabinet 53. intermediate its ends the shaft 6| has provided thereon a knurled portion 51A. Near one end of the shaft 5| there is affixed a gear 5d (Figs. 2 and 17). The gear 54 is operatively associated with a gear portion 65 formed on the hub of meter gear lis (Figs. 2 and 17). One revolution of the shaft 45 moves the gear 54 and therewith the shaft 5| approximately 120. On the opposite end of the shaft 5! there is mounted a manual control knob 56 (Figs. 18 and 19). To lower the turntable 3d the knob 55 and the gear 55 must be rotated in a clockwise direction (Figs. 17 and 19). The clockwise movement (Fig. 17) of the gear 65 moves the worm gear 39 in a counterclockwise direction (Fig. 2) to lower the turntable 34. The turntable 34 may be low ered any desired distance depending upon the number of records which the operator wishes to play. The distance the turntable is lowered depends upon the distance an indicator finger 51 is moved relative to an indicator dial 5B (Fig. 18). The indicator iinger 51 has a sleeve portion 51A, the left end of which has a knurled portion 51B as shown in Fig. 19. The sleeve portion 61A is mounted on the shaft 5! preferably in the manner shown in 19 to rotate relative thereto. Each time the turntable elevating mechanism operates to elevate the turntable, as previously described. the shaft 5l and therewith the gear 54 (and knob 56 are rotated approximately 120. This radial movement of the shaft 5l is greater than the distance between two adjacent numbers on the indicator dial 58 (Fig. 18), which is approximately 30. 'The mechanism for reducing the movement of the indicator finger 61 relative to the movement of the shaft' 6I is shown in Fig, 19. This mechanism includes a shaft 1l fixed on the bracket 62 and the cabinet portion 63 preferablyv in the manner shown in Fig. 19. A member 12 with knurled portions 12A and 12B is rotatably mounted on the shaft 1I. The knurled portion 12A is in continual engagement with the knurled portion 51A and the knurled portion 12B is in continual engagement with the knurled portion @1B of the member 61A. The diameters of the knurled portions 61A, 12A and 12B and the knurled portion of the member 61A are proportioned so that when the shaft 6l is rotated 125 the finger 51 will rotate 30. Thus, it is evident that when the turntable elevating mechanism is operated when a record is discarded, the indicator El will move to the next succeeding number on the indicator dial 98 (Fig. 18). Also, when the operator manually lowers the turntable, he may turn the knob $6 sufciently to move the indicator el to the number on the dial 58 correspond to the number of records to be played, and the turntable will be lowered to the proper position t play the top record on the turntable and each succeeding record thereafter.

Pickup arm mounting and mechanism for moving the pickup arm Y The mounting of the pickup arm, and the mechanism for moving the pickup arm is illustrated in Figs. 15 and 16. A pickup arm 15 is mounted on a pedestal 16 which is xed to the base plate i at one side of the turntable 3d as shown in Figs. 1 and 15. The pickup arm i5 is mounted in such a manner that it may be moved in a horizontal or a vertical plane. At the free end of the pickup arms there is provided a reproducer or pickup 11 with a stylus 18 which is adapted to cooperate with a record on the turntable i to reproduce it. Intermediate the ends of the pickup arm 15 there is pivotally connected thereto a lever 8o in a suitable manner such as shown in Fig. 15, To one end of the lever Sil, there is aixed a downwardly extending pin 8l. A spring 82 is `connected to the pickup arm 15 at 15A and associated with the lever 88 in the manner shown in Fig. 15 to maintain the lever 8B in the fu1l-line position shown in that figure. As will be evident from the description hereafter, when the raised pickup arm 15 is moved from its outwardmost position shown in Fig. l toward the turntable 34 and the top record on the turntable is a 12-inch record, the pin 8l will exten-d in the plane of the 12-inch record on the turntable and serve to position the stylus 18 of the pickup arm 15 over the initial playing groove of that record. As the pickup arm is lowered to bring the stylus 1B into engagement with the ini tial playing groove of the top record on the turntable, the pin 8l is raised out of engagement with the top record on the turntable in a manner to be described hereinafter to permit the pickup arm to move toward the center of the turntable as the stylus 18 is tracking the playing groove of the top record.

As shown in Fig. 15, the pickup arm 15 is pivotally mounted on a pin 83 which is xed to a plate 84. The free end of the plate 84 is operatively associated with the lever 89, and the pivoted end of the plate 8f! is pivotally connected to a plate 85 by pin 83. This plate 85 is affixed to a tubular shaft 86 which is supported by the pedestal 16 and extends downwardly and below the base plate l 5. A lever 81 is fixed to the lower end of the tubular shaft 85 and, when moved in a horizontal plane, is adapted to transmit a corresponding movement to the pickup arm 15. A

l l .In

spring 88 engages the bottom of the base plate l5 at 15A and is coiled around a pin 88B in such a manner that the free end thereof normally extends in the path of the member 81. When the spring is in its normal position and the lever 81 is moved in a counterclockwise direction (Fig. 15) the lever 81 engages the spring 88 and thereafter is moved against the biasing action thereof. The spring 88 is adapted to be moved out of the path of the lever 81 in a manner to be described hereafter. A pin 89 is provided within the tubular shaft 8e and is adapted to be moved relative thereto in a vertical plane to engage and move the lever for elevating the pickup arm 15 and for moving the pin 8l of the lever 80 into the plane of the top record on the turntable 34. The means for supporting and moving the pin 89 will be described hereafter.

A shaft $28 is mounted on a bracket 9| for rotating relative thereto. A cam wheel 92 is fixed to the upper end of the shaft 99. This cam wheel is cylindrical in shape and is provided with the cam surface 93 around the periphery of its upper surface. The cam surface 93 has cam portions 93A, 98B and 93C. rlhe lower end of the pin 89 is in continual engagement with the cam surface 93 and is supported thereby. Also provided on the upper surface of the cam wheel 92 are members 9A and 95. When the cam wheel 92 is stationary, the member .98 is in engagement with the spring 88 to maintain its free end out of the path of the lever 31. This position of the member 94 in relation to the spring 88 is shown in Fig. 15. When the member 913 is moved with the cam wheel 92 from the position shown in Fig. 15, it is moved out of engagement with the spring 88 and permits the free end of spring 88 to move in the plane of movement of the lever 81. The member 95 extends upwardly from the surface of the cam wheel 92 in the plane of the lever 81 and is adapted to move the lever 81. On the peripheral wall of the cam wheel 92 there is provided a groove Ribbon members 91 are connected to the cam wheel 92 in the groove 96. The opposite ends of the ribbon members 91 are connected to cam members of record-elevating mechanisms which will be described hereafter.

To the lower end of the shaft 99, there is fixed a lever 98 to rotate therewith. The lever 98 is normally biased by a spring 99 to the position shown in mg. 16. Spring 99 is secured to bracket i8 by pin 99A and is hooked into lever 98 at 98A. A downwardly extending pin 189 is provided on the free end of the lever 98. This pin is in continual engagement with a cam surface |91 on a cam wheel H82. rihe cam surface IUI is provided with portions !8 lA-l ID. The cam wheel i112 is fixed to the shaft 21 to rotate therewith. When the cam wheel H52 is stationary, the pin lll of the lever 98 is in engagement with the cam portion IMA. When the cam wheel I 02 begins to rotate through a cycle of operation, the cam portion lilB moves into engagement with the pin 189 and moves rthe lever 98 in a counterclockwise direction (Fig. 16) against the biasing action of the spring 99. When the lever 98 is moved in a counterclockwise direction (Figs. 15 and 16), the shaft 98 and the cam wheel 92 move therewith in a corresponding direction. When the cam portion l 91C comes into engagement with the pin 188, `the lever 98 stops its counterclockwise movement and is maintained in this position until the cam portion MHD comes into engagement with the pin 188. rThe cam portion 10| D permits the spring 99 to move the pin i90 of the lever 98 into engagement with fthe cam portion I9IA during the rotation of the cam wheel |92. The movement of the pin |99 along the cam portion moves therewith the lever 98, the shaft 99 and the cam wheel 92 in a clockwise direction (Figs. 15 and 16). When the pin |99 comes into engagement with the cam portion I9IA, the lever 98, the shaft 99 and the cam wheel 92 are back in their respective normal positions and the rotation of the cam wheel |92 stops.

The counterclockwise movement (Fig. 15) of the cam wheel 92, during a cycle of operation of the cam wheel |92, performs the following functions in sequence. When the cam wheel 92 is stationary, the lowerend of the pin 89 is in engagement with the cam portion 93A of the cam surface 93. As the cam wheel 92 begins to rotate in a counterclockwise direction (Fig. 15) the cam portion 93B moves into engagement with and raises the pin 89. By the time the cam portion 93C moves into engagement with the pin 89, the pin 89 has been raised to its uppermost position. The upward movement of the pin 89 pivots the pin 8| of the lever 89 into the plane of a top record on the turntable 34 and raises the pickup arm out of engagement with the top record on the turntable. While the pin 89 is being raised, as has just been described, the member 94 moves out o-f engagement with the spring 88 to move its free end into the path of the lever 81. Thereafter, the member 95 engages the lever 81 and moves it against the biasing action of the spring 88 in a counterclockwise direction (Fig. 15) The counterclockwise movement of the lever 81 transmits corresponding movement to the pickup arm 15 to move it in a corresponding direction to its outwardmost position shown in Fig. 1. While the pickup arm 15 is being raised and moved to its outwardmost position, the ribbon members 91 are moved by the cam wheel 92 to operate the recordelevating mechanism to be described hereafter.

After the functions just described have been performed by the counterclockwise movement (Fig. 15) of the cam wheel 92, a clockwise movement (Fig. 15) is imparted to the cam wheel 92 and this clockwise movement of the cam wheel performs the following functions. First, the ribbon members 91 are moved to operate the record-elevating mechanism to be described hereafter. During this operation, the member 95 is moved out of engagement with the lever 81 and the spring 98 moves the lever 81 in a clockwise direction (Fig. 15). The clockwise movement of the lever 81 transmits a corresponding movement to the pickup arm 15 and moves the pickup arm over the initial playing groove of the top record on the turntable 34. After the pickup arm is over the initial playing groove of the top record on the turntable, the member 94 engages the spring 88 and moves it out of engagement with the lever 81. Thereafter, the cam portion 93B permits the pin 99 to move downwardly into engagement with the cam portion 93A. This downward movement of the pin `89 permits the pin 8| of the lever 89 to l move out of the plane of the top record on the turntable and permits the pickup arm 15 to be lowered into engagement with the initial playing groove of the top record on the turntable. When the cam wheel 92 finishes its clockwise movement it is in the position shown in Fig. 15.

Record-elevating apparatus The apparatus for elevating the top record from the turntable 34 comprises two identical mechanisms mounted on the base plate I5 beyond the 10 periphery of the turntable 34 and diametrically opposite relative thereto, as shown in Figs. 1 and 2. Corresponding parts of each mechanism have been given the same number for convenience of description. One of these mechanisms is shown partly in section in Fig. 2, and will be described in detail. This mechanism includes an annular cam member |94 fixed to the bottom of the base plate i5. Cam portions I94A-I94D are provided on' the bottom surface of the cam member |94. A pedestal |95 havinga tubular portion |96 is fixed to the top of the base plate I5 directly above the cam member |94. A pin |91, provided with a flanged portion |99 intermediate its ends, extends through the tubular portion |96 and the annular cam member |94 and is connected by a coil spring |99 to a suitable fixed object, preferably the cam member |94. As shown in Fig. 2, one end of the spring |99 is connected to the cam member |94 at I99A and its opposite end is connected to the iianged portion of the pin |91 at |99B. The spring |99 normally maintains the pin |91 in the position shown in Figs. 1 and 2. The spring connection of the pin |91 permits the pin |91 to be rotated about its axis and to be moved longitudinally along its axis. Both of these movements are against the biasing action of the spring |99. A head II9 is provided at the upper end of the pin |91. Intermediate the flanged portion |98 and the head II9, swivel plates III and i I2 are connected to the pin |91 to rotate therewith, Both plates have free ends extending outwardly from their connections to the pin |91 and are angularly displaced relative to each other in a horizontal plane, as shown in Fig. 1. When the pin |91 is rotated in a clockwise direction (Figs. 1 and 2), the free end of plate II2 is adapted to move over the surface o f the top record on the turntable 34 and the free end Qf the plate II I is adapted to move between the two top records on the turntable 34. A knife portion IIS is provided at the free end of the swivel plate I I I to facilitate the movement of the plate III between records. A curved portion vI I4 is provided at the end of the swivel plate I I2 which is connected to the pin |91. This curved portion I I4 separates the bottom surface of the free end of the plate II2 a distance corresponding to the thickness of one record from the upper surface of the free end of the plate I I I. The plates I I I and I I2 are maintained in engagement with each other, as shown in Fig. 2, by spring elements Il 5 and IIB. The spring IIB is placed between the flanged portion |98 and the bottom of the plate III, and the spring II5 is placed between the top of the plate II2 and the head I I 9. The spring elements I I5 and I I9 permit the plates III and I|2 to adjust themselves relative to each other in a vertical plane when they meet an obstruction such as a record of abnormal thickness.

A cam member I|8 is afiiXed to the lower end of the pin |91. This cam member is cylindrical in shape and on the periphery of its upper surface there are formed cam portions I |8A-I |8D. The spring |99 maintains these cam portions of the cam member II8 in continual engagement with the cam portions of the cam member |94. When the pin |91 is in its normal position, the cam portion I IBA is in engagement with the cam portion I94A of the cam member Fig. 2. A groove I2I is formed in the peripheral wall of the cam member I I8. The ribbon members 91 are fixed to the groove I2I as by pins IgIA and are adapted to be guided thereby.

|94, as shown in y The two record-elevating mechanisms located on diametriically opposite sides of the turntable are operated by the cam wheel 92 (Fig. 15) which is connected to them by the ribbon members 97. When the cam wheel 92 is driven in a counterelockwise direction (Fig. during a cycle of operation of the cam wheel |02, the cam members IIB, the pin |57 and the plates and ||2 are rotated in a clockwise direction (Fig. 1) against the biasing action of the springs |09. As the cam membersA ||3 are moved in a clockwise direction (Fig. 2), the cam portions ||3Aof the cam members E 8 move into engagement with the cam portions |34B of the cam members |04. This lowers the pins |97 at the same time that they are moving in a clockwise direction (Fig. 2). The continued clockwise movement of the pins itl moves the plates ||2 over the upper surface of the peripheral edge portions of the top record on the turntable (Fig. 7). While these plates are still in engagement with the top surface of the top record on the turntable, the plates move between the two top records on the turntable 34 (Fig. 7). Immediately thereafter, the plates H2 move out of engagement with the top record Yon the turntable and the cam po-rtions IiSA of the cam members IIB move into engagement with cam portions |040 of the cam member |94, as shown in Fig. 8. This permits the springs |39 to raise the pins |97 and therewith the plates iil. Since, at this time, the plates are between the two top records on the turntable, the top record is raised by these plates I as shown in Fig. 8. The plates of the record-elevating mechanisms are maintained in this position while the elevated record is gripped by a record-moving mechanism to be described hereafter and is lifted off of the plates After the recordmoving mechanism has performed its function, the cam wheel 92 begins to move in a clockwise direction (Fig. l5) back to its original position shown in Fig. 15. This clockwise movement of the cam wheel 92 permits the cam members ||8, the pins |07 land the plates and ||2 to move in a counterclockwise direction (Figs. 1 and 2) in response to the biasing action of the springs |59. As the cam members i I8 move in this counterclockwise direction (Fig. 8) the .cam portions HSA move into engagement with the cam portions |4B of the cam member |94 and move the pins |97 and the plates and ||2 downwardly during their counterclockwise movement. Continued counterclockwise movement of the cam members H8, pins |97 and plates and ||2 in response to the biasing action of the springs |99 moves the plates and Il?. beyond the peripheries of the records on the turntable. Immediately thereafter, the Icam portions HSA of the cam members H8 move out of engagement with the cam portions |0413 and into engagement with the cam portions |04A. 'I'his permits the pins |97 and the plates and ||2 to return to their normal elevation shown in Fig. 2, in response to the biasing action of the springs |09. When the cam members H8 have reached the position shown in Fig. 2, one cycle of operation of the record-elevating apparatus is completed.

Record-moving mechanism The record-moving mechanism is best illustrated in Figs. 1 6, 9 and 11-14 and includes a pair of brackets |39 fixed to and extending above the base plateV i5, as shown in Fig. 1. To each of the brackets |39 there is 'ailixed a bearing pin |3|. To each of the pins |3| there is connected a member |32 which is rotatable about the common axis of the pins |3| in a position diametrically opposite to each other. Fixed to one of the members |32, as shown in Fig. 1, is a segmental gear |34. The segmental gear |34 is adapted to rotate the members |32 around the common axis of the pins |3|. The mechanism for driving the segmental gear |34 will be described hereafter.

A housing |35 (Fig. i), provided with a groove |36, is supported by extension portions |37 provided on the members |32, as shown in Fig. 1. This connection of the housing |35 to the members |32 is such that the housing |35 may be rotated around its longitudinal axis relative to the members |32. The housing |35 is adapted to be held in two stable positions relative to the members |32. This is accomplished by a springbiased ball |38 which is adapted to engage, at different times, the notches |39 and |49, provided in the housing |35 (Fig. 5). The notches |39 and |49 are spaced 180 from each other. When the housing |35 is in the position shown in Fig. 5, the spring-biased ball |38 is in engagement with the notch |39. When the housing |35 is rotated about its longitudinal axis relative to the member |32, from its position shown in Fig. 5, the spring-biased ball |33 comes into engagement with the notch |40. At one end of the housing |35, there is afliXed thereto a short tubular shaft |42 to which is aiiixed a pinion gear |43. As will be described hereafter, the pinion gear |43 is adapted to cooperate in rotating the housing |35 about the axis of the shaft |42.

A pair of segmental gear members 44 and |45 are connected to the other end of the housing |35 by pins |46 and |47, respectively, and are adapted to be moved relative to the housing |35 in planes parallel to its longitudinal axis. The means for moving the gears |44 and |45 will be described hereafter. A pair of arms |43 and |49 are connected to the segmental gear members |44 and |45, respectively, by pins |50 and |5|. The connections of the arms |43 and |49 to the gear members |44 and |45, respectively, permit the arms to move With the gears |44 and |45 in planes parallel to the longitudinal axis of the housing |35 and permit the arms |48 and |49 to move relative to the gears |44 and 45 and to each other in a plane normal to the longitudinal axis of the housing |35. Cam portions |48B and |49B are formed, respectively, on the ends of the arms |48and |49, as shown in Figs. 1 and 5. When the gear |44 and therewith the arm |48 are moved in a clockwise direction (Fig. 1) and the gear |45 and therewith the arm |49 are moved in a yeountertlockwise direction (Fig. 1) to the pQSition shown in Fig. 6 by means to be described hereafter, the cam portions |48B and |49B are moved into engagement with each other. With the portions |48B and |49B in engagement with each other, the opposite ends of the arms |48 and |49 are in gripping engagement with the upper and lower surfaces of an elevated record, as illustrated in Fig, 9, Record-gripping portions |48A and |49A of compressible material such as rubber are provided on the record-gripping ends of the arms |43 and |49, as shown in Figs. 5 and 9. When the arms |48 and |49 are in engagement with a record, as illustrated in Fig. 9, the record-gripping portions |48A'and |49A are compressed to firmly grip the record.

The end of the housing |35, through which extend the arms |48 and |49, is provided with an opening |52 (Fig. 6). The opening includes portions |52A, |52B and |52C. When the arms |48 and |49 are in their outwardmost positions shown in Fig. 1, the arm |48 passes through the portion |52A of the opening |52, and the arm |49 passes through the portion |520 of the opening |52. When the arms |49 and |49 are in a recordengaging position, as shown in Figs. 3 and 9, the arms |48 and |49 pass through the portion 152B of the opening |52.

The segmental gears |44 and |45 are driven by a mechanism which includes a shaft |54 mounted in the housing- |35 to rotate relative thereto, as shown in Figs. 1 and 5. A gear |55 is fixed to one end of the shaft |54 to rotate therewith and is adapted to operatively engage the segmental gears |44 and |45, as shown in Fig. 5. Gears |56 and |59 are xed to the opposite end of the shaft |54 to rotate therewith, gear |58 being adapted to be driven by a segmental gear |51. The segmental gear |51, which has a gear |59 affixed to its hub, is pivotally connected to the base plate i in a suitable manner, such as that shown in Fig. 5. As shown in Fig. l, the gear |59 is adapted to be in continual engagement with a gear |68. The gear |69 is fixed to a shaft |6| which is rotatably7 supported by a pair of brackets |62 and |66 (Figs. 1 and 2) which, in turn, are supported in a suitable manner from the underside of the base plate i5. To the opposite end of the shaft |5| there is afXed a segmental gear |65, as shown in Fig. 2. On the lower end of the bracket |63 there is pivotally connected a member |66 having a gear portion |66A and an extension pin |6613. One end of a spring |61 is connected at |61A to the member |66 and the other end is connected to a suitable fixed object, preferably the pin |6113 in the bracket 28A. The spring |61 maintains the gear portion |66A in continual engagement with the gear |65 and the extension pin |66B in continual engagement with a cam surface |66 of the cam wheel |69, as shown in Fig. 2. rThe cam wheel |69 is fixed to the shaft 21 to rotate therewith, It is cylindrical in shape and, as shown in Fig. 12, the cam surface includes the cam portions |68A-|68D. When the cam wheel |69 is stationary, the spring |51 maintains the member |66 in the position shown in Fig. 2. With the member |66 in this position, the end of the extension pin |66B is in engagement with the cam portion |66C and the members |66, |65, |66, |59, |51 and |58 are maintained in their respective positions shown in Figs. 1, 2 and 5. With the gears |51 and |59 in these respective positions, the gear |51 will be in engagement with the pinion gear |58when the housing |95 and the arms 14S-and |49 are in the positions shown in Figs. l and 5. Immediately after the top record on the turntable has been elevated ,in a manner previously explained, the cam portion |5821 of the cam wheel |69 moves into engagement with the extension pin |66B and moves the member |66 in a clockwise direction (Fig. 2) against the biasing action of the spring |61. As the member |66 rotates in a clockwise direction (Fig. 2) the gea-r |65 and therewith the shaft |6| and the gear |59 are rotated in a counterclockwise direction (Fig. 2). The counterclockwise movement (Figs. 1 and 2) of the gear |69 moves the gears |59 and |51 in a clockwise direction (Figs. l and 5). When the cam surface |681) moves into engagement with the extension pin |5613, the gears |51, |58 and |55 have rotated sufliciently far to move the segmental gears |44 and |45 and the arms |46 and CFI |49 to the positions shown in Figs. 3, 6 and 9. With the arms |48 and |49 in these positions, their respective cam portions |48B and |49B are in engagement with each other and the respective record-gripping portions |48A and |49A of the arms |48 and |49 are in engagement with an elevated record, as shown in Figs. 3 vand 9. After the arms |48 and |49 are moved to and from either a record-reversing or a record-discarding position, which movements will be described hereafter, the cam portion |68B moves into the path of the extension pin |66B. This permits the spring |61 to move the member |66 in a counterclockwise direction (Fig. 2) and the members |60 and |65 in a clockwise direction (Fig. 2). Th'e clockwise movement of the gear |69 moves the segmental gear |51 into engagement with the pinion gear |58 to rotate the shaft |54 and the segmental gears |44 and |45 back to the position shown in Fig. 1 for moving the arms |48 and |49 out of the record-engaging positions shown in Figs. 3 and 9.

After the arms |48 and |49 have gripped an elevated record, they are then moved upwardly to either of two positions-a record-reversing position, as shown in dotted lines in Fig. 3, or a record-discarding position in which position the arms |48 and |49 are adjacent a magazine |15. The magazine |15 is xed to the base plate I5, as shown in Fig. 3. It includes a back plate |16 to which is affixed a pair of pins |11 and a pair of wall portions |16. The pins |11 are spaced in such a manner that when the arms |48 and |49 are moved to the record-discarding position, they move between these pins, and the lower peripheral edge of the record gripped thereby is above the top surface of the pins |11. rEhe pins |11 function to support records on their lower peripheral edges which have been released by the arms |49 and |49. There are provided rubber sleeves |11A on pins |11. The wall portions |18 are fixed to the upper end of the back plate |16 and function to guide the records released by the arms |48 and |49 as they slide on the pins |11 toward the back plate |16.

IThe mechanism for actuating the arms |68 and |49 for releasing a record gripped thereby includes ra segmental gear |19 fixed to the shaft |86 to rotate therewith. The shaft |86 is rotatably supported by the brackets |8| and |82. The bracket |8| is supported by the base plate I5 and the bracket |82 (Fig. 14) is supported by a suitably stationary object not shown in the drawings. When the housing |35 and the arms |48 and |49 yare moved to the record-discarding position, the pinion gear |56, movable therewith is moved to the dotted-line position shown in Fig. 5. In this position, the pinion |56 is adapted to be driven by the segmental gear |19. The shaft |99 also has affixed thereto, as shown in Fig. 14, a gear |83 to rotate therewith. There is provided for driving gear |89 and shaft |88 a gear train consisting of drive gear 26A fixed to shaft 21, idler gear 26B fixed to shaft |94A anddisposed to mesh with gear 26A, and pinion |84 also fixed to shaft |84A to be driven by gear 26B and to mesh with gear |83. Thus since gear 26 drives shaft 21, shaft |89 may be driven from shaft 21 in 1 to l ratio. One revolution of the gear 26 functions to move the arms |49 and |49 out of record-engaging position when these arms are in the record-discarding position. One revolution of the gear 26 in a clockwise direction, driving through gears 26A, 26B and |84, rotates the gear |89 one revolution in a countercl-ockwisel direction.

The counterolockwise movement of the gear |83 moves the segmental gear in a corresponding direction. The counterclockwise ,movement of the segmentalgear 119, when in engagement with the pinion |55, moves the pinion 5o. the shaft |54 and the pinion |55 in a counterclockwise direction, also. The lcounterclockwise movement of the 'pinion |55 moves the segmental vgears |44 and |45 for moving the arms |48 and |49 out of record-engaging positions.

The movement of the housing and the arms |43 and |49 from the full-line position shown in Fig. 3 to the record-reversing position or the record-discarding'position previously referred to is performed by a mechanism which includes the lsegmental gear |34 xed to the member '|32 (Figs. 1 and 4), which has been previously described. The segmental gear 34 is in continual operative engagement with another segmental gear |35 fixed to a shaft 189 to rotate therewith. The yshaft A09-is rotatably Ysup-ported by a bracket |81 which is fixed to the bottom of the base plate I5, as shown in Figs. 4 and 5.

The shaft |83 also has aixed thereto an arm |89, one end of which `is pivotally connected to a beam |90 at |09A (Fig. 4). Intermediate the ends of the beam |90, there is provided a pin |9|. The opposite end of the beam 90 is provided with a bifurcated portion |90A as shown in Fig. 4, which serves as a sliding connection between the beam |90 and the shaft 21. The shaft 21 has aiiixed thereto a cam wheel |92 to rotate therewith. The pin |9| is adapted to be guided by cam groove areas ISS-|91 in the face of the cam wheel 92 to move the beam 99 over two different paths during diierent cycles of rotation of the cam wheel |92. The beam |90 is moved over one of these paths when the pin |9| is guided by the cam groove areas |99, |94, |95 and |91 and it is 'moved over a different path when the pin |9| is guided by the cam groove areas |93, 94, |95 and |91.

A member |99 is pivotally connected to the face of the cam wheel |92 in the common area of grooves |94, |95 and |96. As will be described presently, themember 99 is adapted to be moved to its dotted-line position (Fig. 4) at the beginning of a cycle of operation of the cam wheel |92, shown in Fig. 4 by a mechanism to be described presently. The member |99 is provided Ywith an extension pin 200 which extends through aslot 20| provided in the cam wheel 92, as shown in Figs. 4 and 13. A pair of L-shaped levers 203 and 204 are pivotally connected intermediate their ends to an arm 205 Xed to the bracket l1 (Fig. 4). The right-'hand end of the lever 293 is adapted to be moved into the path of the pinii '(Figs. 4 and 13), Yand the right-hand end of the lever 294 is adapted to be moved into the path of the heel 58B of the member 58 shown in Fig. 10. The opposite ends of the levers 203 and 20e are swivelly connected to a lever 299 (Fig. 4). The opposite end of the lever 206 is connected to a manual control lever 291 in a suitable manner shown vin dotted lines in Fig. 1. The lever 201 extends up through a slot 208 in the base plate |5 andhas a knob 209 fixed to its free end. The lever 201 is adaptedto be moved to two positions on the base plate marked one-side and bothsides respectively. When the lever 201 is moved tothe both-sides position, it moves the levers 203 and 204 to their respective uppermost positions, shown in Fig. y4. In these respective positions, the lever 203 is out of the path of the pin 200 (Fig. 4) and the1ever204 is out of the path `of the member 58 (Fig. 10).

16 W-h-en the lever 201 vis'moved to the one-side position, the vlevers :2,03 and 204 are ymoved to their respective -lowermost positions shown in Fig. 4. When the lever 203is in its lowermost position at the beginning of a cycle of operation of the cam wheel |92 and the pivotal member |99 is in its full-line position shown in Fig. 4, the lever 203 is adapted ,toimove the pivotal member |99 to its dotted-line position. If, at the beginning of a cycle ,of operation ofthe cam wheel |92, the pivotal member |99 is 4in its dotted-line position, the lever 203 will have -no effect on the pivotal member |99. When thelever 204 is in its lowermost position (Fig. 4) at the beginning of a cycle of operation offthe'cam wheel 55 and `the member 58 is in its dotted-line position (Fig. 10), the lever 204 will-change theposition of the member 58 to its full-line position (Fig. 10). If, at'the beginning of a cycle 10i operation of the caml wheel r55, the member 58 is :in its full-line position (Fig. 1.0), the lever 204 `.will have no effect Von .the member '58. Thus, it `will be evident that, 'by moving the lever 201 to its one-side position, applicants apparatus is adjusted to operate to discard a Vrecord from 'the turntable during each cycle of operation and when the lever 20.1 is moved to lits two-side position, applicants apparatus is adjusted to ;op erate'alternately to reverse a record on ythe turntable and Vto discard a record from the turntable during successive .cycles of operation of the apparatus.

The rotation of the cam wheels |02 :and |92 is so timed that, after the top record is elevated vfrom, the turntable, the arms '|48 and '|49 are moved into engagement with the elevated record, and the `pickup arm 15 is moved rto itsoutwardmost position, the cam groove'portion |94-of Athe cam wheel |92 moves into engagement with the pin |9I. Thereafter, the continued rotation of the cam Wheel .|92 moves the beam |90 .to pivot the arm |89 and therewith the segmental gear in a counterclockwise direction (Figs. 4 and 5). The counterclockwise Vmovement of the segmental vgear |85 rotates the segmental gear |34 and the 'members |32 in a clockwise direction (Fig. 5) about the axis of the pins |3|. The clockwise movement of the members |32 moves Jtherewith the housing |35 and the arms |48 and |49to'move the elevated record off-of the plates |I|.

When the member |99 is infits full-line position shown in Fig. 4, the portion 1199A thereof comes into :engagement with the pin .|-9| Aandiguides the Vpin into the cam groove lportieri |95. When the heel portion |99B of the member |99 comes into engagement with the pin |9|, the lmember |99 is rotated to the dotted-line position shown in Fig. I'4. When the pin |9| moves from the cam `groove-portion |94 to the cam groove portion |91 by the path of the cam groove |95, the movement of the beam is limited in such a manner as to `raise the arms |48 and '|49 to the recordreversing position shown by dotted lineslin Fig. 3.

When the cam groove portion |91 comes into engagement with the pin |9|, it moves the beam |90 to pivot the arm |89 and therewith the segmental gear |85 in a vclockwise direction (Figs. 4 and 5). The clockwise movement of the segmental gear |85 moves the segmental gear |34, the members |32 and the housing |35'in acounterclockwise direction (Fig. 5) to lowerthe arms |48 and |49 back to thefull-line position shown in Fig. 3, to place the record grippedA thereby back ori-the plates Thereafter, the plates f|-`|| are 17 moved out of their respective record-supporting positions so that the top record again is supported on the turntable 34. On the next revolution of the cam wheel |92, the arms |48 and |49 are again raised when the pin |9| is guided by the cam groove portion |94. However, at the beginning of this revolution of the cam wheel |92, the member |99 is in the dotted-line position shown in Fig. 4. When the member |99 is in this position, the pin |9| is not obstructed by the portion |99A and is guided from the cam groove |94 to the cam groove |96. Since on this revolution ci the cam wheel |92 the cam portion |94 guides the pin |9| over its full length, the beam |99 is moved further to the right (Fig. 4) than it was moved during the previous revolution of the cam wheel |92 and the arms |48 and |49 are moved correspondingly farther from the turntable 34. When the pin |9| engages the portion |99C, it pivots the member |99 from the dotted-line position shown in Fig. 4 to the full-line position shown in Fig. 4. While the pin 9 is being guided by the cam groove portion |96 to the cam groove portion |91, the segmental gear |19 engages the pinion gear |56 (Fig. 5) to move the arms |48 and |49 out of gripping engagement with the record to thereby deposit the record into the magazine |15. After the record that is gripped by the arms |48 and |49 is deposited into the magazine |15, the cam portion |91 comes into engagement with the pin |9| and begins to move the beam |90 to the left (Fig. 4) and to rotate the segmental gear |85 in a clockwise direction (Figs. 4 and 5). The clockwise movement of the segmental gear |85 moves the segmental gear |34 in a counterclockwise direction to lower the arms |48 and |49 to the positions shown in Figs. 1 and 5.

If, before rotating the cam wheel |92 through another cycle of operation, the lever 203 is moved into its lowermost position shown in Figs. 4 and l 13, it is evident that during the succeeding cycles of operation of the cam wheel |92 and before the member |99 engages the pin |9|, the pin 200 will move into engagement with the lever 203 and move the member |99 from the full-line to the dotted-line position shown in Fig. 4. As is clear from the description above, by this setting of the member |99 on the cam wheel |92, the arms |48 and |49 will again be moved to their record-discarding positions.

When the housing |35 and the arms |48 and |49 are elevated torecord-reversing position previously described, they are rotated 180 about the longitudinal axis of the housing |35 by a mechanism shown in Figs. l, 3 and 5 and which includes the pinion |43. With the pinion |43 in recordreversing position shown in dotted lines in Fig.

3, it is adapted to be rotated 180 about the axis of the shaft |42 by a mechanism which includes a segmental gear 2|2 (Figs. 1 and 5) rotatably fixed to a shaft 2|3 which is mounted on the bracket |62 and a bracket 2 |4 fixed to the bottom of the base plate |5 (Figs. l and 5). The shaft 2|3 also has fixed rotatably thereto, a gear 2|5 (Figs. 1 and 5). driven by a corresponding' gear 2|8 provided on one end of a shaft 2 |1 which is rotatably mounted intermediate its ends on a bracket 2|8 fixed to the underside of the base plate I5, Fig. 5. The opposite end of the shaft 2|1 has a gear 229 which is adapted to be driven by a corresponding gear 22| rotatably fixed to the shaft |80. During a record-changing cycle, after the gear |43 assumes the dotted-line position shown in Fig. 3, the segmental gear 2|2 is moved into driving The gear 2|5 is adapted to be lil engagement with the gear |43 by the rotation of the shaft |80. The rotation of the gear |43 by the segmental gear 2|2 rotates the housing |35 and the arms |48 and |49, 180 about the longitudinal axis of the housing |35 and turns over the record gripped by the arms |48`and |49 so that when the record is again lowered onto the record-elevating plates its opposite side is exposed.

Mode of operation The general mode of operation will now be described. In' this mode of operation it will be assumed that the lever 201 is moved to the bothsides position shown in Fig. l. First a stack of records is placed in centered position on the turntable 34. The .turntable is manually lowered to the proper position by turning the knob 66 until the indicator 61 is moved to the number on the dial 68 (Fig. 18) corresponding to the number of records on the turntable 34. Thereafter the pickup arm 15 is placed in position for reproducing the top record on the turntable 34 and the apparatus is actuated into operation.

After the top record on the turntable 34 is reproduced and the stylus 18 of the pickup arm 15 (Fig. 15) moves into the tripping groove, a tripping mechanism (not shown) is actuated to initiate the rotation of the shaft 21, through a cycle of operation. The rotation of the cam wheels |92, |99 and |92 (Figs. 2 and l5) fixed to the shaft 21 is so timed during the cycle of operation that these cam wheels cooperate in carrying out a record-changing cycle. The rst operation during the record-changing cycle is the lifting of the pickup arm 15 out of engagement with the top record on the turntable 34, and moving it to its outwardmost position shown in Fig. 1. This operation is brought about by the cam wheel |92 rotating the cam wheel 92 in a manner heretofore described. Thereafterthe top record is elevated above the rest of the stack of records on the turntable. This is brought about by the cam wheel -92 (Fig. 15) moving the cam members H8, as has been previously described.

Immediately after the top record has been elevated, the cam wheel |69 (Figs. 2 and 12) functions to move the arms |48 and |49 into gripping relationship with the elevated record, as previously described. Thereafter the cam wheel |92? functions to move the members |32 and therewith the housing |35 and the arms |48 and |49 to a record-reversing position, shown indotted lines in Fig. 3. Then the shaft |80, which is driven from shaft 21 by the gears 26A, 26B, |83 and |84, rotates the housing |35 and therewith the arms |48 and |49, 180 to reverse the record gripped by the arms |48 and |49. After the reversal of the record, the cam wheel |92 moves the members |32 and therewith the housing |35 and the arms |48 and |49 from the record-reversing position to the full-line position shown in Fig. 3, to return the reversed record onto the plates (Fig. 13). Thereafter the cam wheel |09 functions to move the arms |48 and |49 out of gripping relationship with the reversed record and out to their outwardmost position shown in Fig. 1. Then the cam wheels |92 and 92 cooperate with the springs |09 and the spring 88 to move the p-lates out of engagement with the reversed record and to move the pickup arm 15 in a clockwise direction. Thereafter the cam wheel 92 functions to lower the pickup arm 15 to move the stylus 18 into engagement with the initial playing groove or" the top record on the turntable 34 after I9 which the rotation of the shaft 21 and the gear 26 stops and the reversed side of the top record on the turntable 34 is reproduced.

After the reverse side of the top record on the turntable F34 is reproduced and the stylus 18 of the pick-up arm 15 moves into the tripping groove, the tripping mechanism (not shown) is actuated again to initiate the rotation of the shaft 21 and the gear 26 through another` cycle of operation,

The iirst operation which occurs during the cycle of operation, is the lifting of the stylus 18 of the pickup arm T out of engagement with the top record on the turntable 34 and swinging the pickup arm to its outwardmost position in a manner previously described. During the outward movement of the pickup arm 15, the record-elevating plates are operated to elevate the top record on the turntable 34, above the stack of records in a manner previously described.

Next, the arms |48 and 49 are brought into gripping engagement with the elevated vrecord in a manner previously described.

Thereafter, the cam wheel |92 functions to move the arms |48 and |49 to record-discarding position after which the meter gear 44 (Figs. 2 and 12) functions with connecting mechanism to elevate the turntable 34. While the turntable is being elevated, the shaft |89, which is driven .by the gear |83 rotates the gear |19 to move the arms |48 and |49 out of gripping engagement with the record, and the record is deposited into the magazine |15 in the manner previously described.

Next, the cam Wheel |92 functions to move the arms |48 and |49 back to the full-line position shown in Figs. 1 and 3.

Thereafter the cam wheels |02 and 92 cooperate with the springs |89 and the spring 88 to move the plates ll back to their normal positions and to move the pickup arm 15 inwardly from its outwardmost position to move the stylus 18 over the initial playing groove of the top record on the turntable 34. Then the pickup arm 15 and the stylus 18 are lowered into engagement with the record.

The next and following cycles of automatic operation are initiated by an automatic tripping mechanism (not shown) which is actuated each time the stylus 18 moves into a tripping groove of a record.
