61 Claims.

This invention relates to automatic phonographs and has for its principal object to provide an improved phonograph which is adapted to operate automatically for the playing of one or a plurality of records.

One of the objects of the invention is to provide an automatic phonograph which is relatively small and compact and which is, nevertheless, adapted for the playing of any selected number of a large number of records.

*tfurther object of the invention is to provide an automatic phonograph of this type which is adapted to play either or .both sides of any desired number of records.

A further object of the invention is to provide an improved automatic phonograph which is adapted to playing a predetermined number of recordings desired, and to play recordings which have been selected, and to play a sequence of recordings in the event that no selection has been made.

Referring to the drawings, the reference numeral 30 designates a cabinet which encloses the phonograph mechanism with the exception of the selector buttons 3| and bars 32 which carry these buttons, the bars extending through a front wall 33 of the cabinet. The bars 32 extend rearwardly and their inner ends are received in slots 34 formed in a bar 35 which forms part of the base 35 of the machine. The carrying frame is provided with a pair of transverse railp ayin formations 31, upon which ride rollers 33 of the magazine 33. The base 34 is provided with a rearward extension 43 which terminates in a bracket 4| which supports the motor 42 in an oblique position as best seen in Fig. 2. A main frame member 43 extends upwardly from the base portion as best seen in Fig. 2, this frame member being preferably in the form of a substantial plate which serves as a support for practically all mechanisms of the phonograph with the exception of the selector mechanism. the magazine and the elements associated therewith.

The magazine 33 comprises a lower channel member 44 to which are secured two end plates 45 of concave formation (Fig. 2). The upper and outer extremities of the two end plates 45 are connected by bars 43. These bars extend through openings in spacer plates 41 which are of generally trianglar form as best seen in Fig. 2. The spacer plates are maintained in vertical parallel space relation by means of spacer collars 43 through which pass the rods 43. As best seen in Fig. 3 the spacer collars 43 and the plates 41 are arranged in alternate order on the rods 46, so that the plates 41 provide magazine pockets for the records. when the records are lo-v cated in these pockets they stand vertically, each being supported by a pair of the spacer collars 43. The plates 41. a pair of which is located one upon each side of each record, serves to maintain the records in vertical position and in uniformly spaced relation. In the embodiment of the invention illustrated twenty records, of the same diameter, for example. ten-inch records, are mounted in the magazine. It will be understood, however, that the magazine can be readily adapted for agreater or lesser number of records.

The magazine 39 is adapted for transverse movement to an extent at least equal to the distance between the two extreme records in the magazine. This movement enables each record of the magazine to be brought to a substantially central position defined by two turn table elements 43 and 50, so that each record of the magazine may be brought into position to be delivered between the two turn table elements as is best seen in Fig. 1. The buttons 3| and the stop bars 32 are provided in number double that of the record spaces in the magazine, so that in the embodiment of the invention illustrated forty buttons 3| and bars 32 are. provided.- The twenty buttons 3| on the left-hand side of the machine constitute a group which corresponds to the recordings on the righthand sides of the records twenty buttons 3| on the right-hand side constitute a group which correspond to the recordings on the left-hand sides of the records in the magazine. Suitable indicia (not shown) may be associated with eachbutton so as to in the magazine. The

identify the recording with hich it is associated. i

As has previously been indicated, the magazine is supported by the rollers 33 which are mounted on a channel member 44. The channel member 44 carries on its under side a pair of rollers 5| which ride in a transverse slot 52 provided in the base member 36. The cradle member 44 also carries, adjacent its center, a depending member 53 which extends through the slot 52 and carries a nut 54. The nut 54 receives a screw 55 which is rotatably mounted in bearings 56 which depend from the under side of the base 36. The screw 55 is driven in one direction or the otherby means of a pulley 51. over which passes a belt 58 driven in manner hereinafter to be described. A portion of the screw 55 extends beyond one of the bearings 66 is mounted a nut 59 whichlis held against.

rotation by suitable .means, for example, by means of a rod 66 which extends into a slot 6| in the nut. The nutv 59 is provided with two projections 62 which are located in alignment with the arm 63 of a switch 64. It will readily be understood that when the screw 55 is rotated so as tocause the nut 54 to move in one direc-' tion, for example, upwardly as viewed in Fig. 15, the nut 59 will also move upwardly but at. a much lower speed. 1

When the nut 54 has reached the end of its travel, the lower projection 62 will have engaged the arm 63 of the switch 64 and swung it upwardly'to such an extent that the switch is bar 46. A bail 68 comprising a main, straight portion and two small end portions is pivotally mounted on the bar 61 by means of openings in the end portions. As best seen in Fig. 9, these end portions are located adjacent the walls 45 of the magazine 39, being separated therefrom by meansof washers 69. -Upon the bar 61 on the inner sides at, theends of the ball 68 are freely mounted two sleeves. 'l0. At their adjacent ends the sleeves 16 are provided with flanges II which are separated by a spacing sleeve 12, which. like the'sleeves I0, is slidable longitudinally upon the bar 61. As best seen in Fig. 9, the lengths of the sleeves I0 andthe sleeve "are such that together they are somewhat shorter than the distance between the ends of the ball 68, the difference being atleast equal to the width of one of the bars 32. Adjacent their outermostends the sleeves l0 rigidly carry arms 13 which extend downwardly and are-bent outwardly slightly with respect to their bosses whereby they are mounted snapped, the handle being then in the dotted line position shown in Fig. 15. The switch 64 is connected to the motor in such a way that this actuation of the switch causes reversal of the motor with the result that the nut 54 moves in opposite direction, that is, downwardly as is viewed in Fig. 15, and the nut 59 moves in similar direction, its other projection 62 becoming operative to swing the switch arm 63 back towards its full line position, whereupon the switch snaps over and again reverses the direction of the motor. The position of the nut 54 at which reversal of the motor occurs can be adjusted by means of contact screws 65 which are mounted in the projection 62. This adjustment should be such that every one of the records in the magazine 39'must be located oppo-' site the record playing position defined by the turntable elements 49 and 50 during each continuous movement of the magazine.

It may here be noted that the switch 64 is a double pole double throw switch of the toggle type and that it controls two circuits which insure the operation of the motor 42 in opposite directions. Thus the motor 42 may he a shaded on sleeves 10. A coil spring 14 is mounted around the sleeve 12 and is adapted to bear against the adjacent end flanges of the sleeves Ill. When, however, one of these sleeves is arrested,,.the magazine being in' movement, which arrestment is effected in the manner hereinafter described, the spring 14 is compressed and the two .,end flanges of the sleeves 16 bear against the sleeve 12. Upon each sleeve 10 is rotatably mounted a sleeve 15 which is held against longitudinal-movement by the inner end flange on the sleeve ill and the boss of the arm 13 at the other end of the sleeve 10. Each sleeve 15 has rigidly mounted thereon a forwardly extending pin 16 which normally rests upon the upper edge of a bar ll which extends along the whole length of the series outer sleeve 15 carries a clevis 8| on which is pivpoie motor having two shading windings, one of which is adapted to be closed by the switch 64 in one position, and the other of which is adapted to be closed by the switch 64 in its other position. Of course, any known type of reversing motor may be employed if desired. Thus, as shown in Fig. 30, a reversible motor 42 of the capacitor type may be employed, the capacitor associated with the motor being designated by the reference numeral 42. When the arm 63 of the switch is snapped into the position shown in the full lines of Fig. 15, the motor drives the turntable elements in counter-clockwise direction as viewed in Fig. 2. .As a result of this motion the nut 59 will move towards the dotted line position as shown in Fig. 15, and as this motion brings the nut 59 slightly above its position as shown in Fig. 15, the switch 64 snaps to reverse the withincertain limits in either direction, the outmotor and cause rotation of the turn table eletends a round bar 67 which is located in the forward part of the magazine 39, the bar 61 being located below and slightly rearwardly of the front otally mounted a dog 82. Each dog 82 extends outwardly in the longitudinal direction and its outer end is provided with a flat detent face 83 which is adapted to engage the bars 32 in the manner hereinafter more particularly described with reference to Figs. 10, 11, 12 and 13.

Each inner sleeve 16 carries a rearwardly projecting radial rod 84, the outer end of which is .slotted at 85 as best seenin Figs. 10, 11, 12, 13 and 13a. These slots 85 receivethe bar 68 and are so arranged that the sleeves l8 and 15 may move to a limited extent on the bar 61 without disturbing the location of the bar 68 within the slots 85. The rod 84 extends through an arcuate slot 86 in the outer sleeve 15. This slot has a certain limited length so that when the bar 68 is moved er sleeves l5 and the elements mounted thereon remain stationary. When, however, the bar 68 is subjected to a greater movement the pins 84 .will engage the ends of the slots 86 and cause sleeves 15 to rotate with the sleeves 16. The bar 68, the pins 84 and the inner sleeves ID are biased tothe position shown in Figs. 10, "12 and 13a by means of springs 9i which may be anchored to the bar 66 and to any suitable part of the -magazine framework. The outer sleeve 15, to-

gether with the rod 16 and the dog 82 are resiliently biased in the clockwise direction as viewed in Figs. 10, 11, 12 and 13, for example, by means of a spring 93 which is secured to the outer sleeve 15 and to a stationary part of the magazine the upper side as viewed in Fig. 8, the dog 82 on the left-hand sleeve 18 engages a detent 81 on the next bar 82. The arrestment of the left-hand sleeve 18 will result in compression of the spring 14 until further relative approaching movement of the two sleeves 18 isprevented by the inter- 10. The effective dog a: does not attain this position, however, since it engages the forward side of the projection 81, being thus left free for cooperation with the next bar 32,.when translation of themasazine is resumed.

The shaft 84 of the motor 42 extend upwardly and forwardly in oblique direction on the right- Fig. 2), this shaft being supported on suitable mediate sleeve 12. It will be noticed with reference to Fig. 9 that the left-hand arm '13 is now located in alignment with the bar-32 which arrested the magazine, whereas, the right-hand arm 13, which is in alignment with the righthand end of the right-hand dog 82, is out of alignment with all the bars 32.

It may here be noted that after a record is played and is returned to the magazine a contact 88 on a swinging arm 88 engages the bar 88, thus rotating the dog 82 away from the detent 81 and into alignment with a recess 88 formed in the upper side of the bar 32 as shown in Fig. 11. Consequently the dog 82, together with the associated sleeves 18 and 18, are moved to the left, that is, in the upward direction as viewed in Fig.

9. The dog 82 is no longer held by the bar 32 which arrested it. It will be noted that during the movement of the pin 84 from its position in Fig. 10 to its position in Fig. 11, the arm 13 is brought into close propinquity to or contact with the bar 32 which arrested the magazine. Since this bar was not displaced from its normal position it is not actuated by the arm 18.

When one or more of the bars 32 are pressed inwardly the bar 11 is elevated to the position shown in Fig. 12. The resulting elevation of the pins 18 brings both the dog 82 into the position shown in Fig. 11 or 12. Consequently these dogs will miss the bars 32 which have not been displaced inwardly, as will be understood from Fig. 11. Consequently movement of the magazine will take place, to the left, for example, until the left-handdog 82 strikes a portion 82 of the first displaced bar 32 which it meets. Of course,

it will be understood that when the magazine ismoving to the left the right-hand dog 82 will merely slip over in bars 32 with which it comes into contact. During reverse movement, that is movement to the right, the night-hand dog 82 is effective in arresting the magazine and the lefthand dog 82 is inoperative. After the record corresponding to the rod 32 which has been displaced inwardly, as shown in Fig. 12,'has been played, the contact member 88 of the arm 88 engages the bar 88 in the manner shown in Fig. 13 and the inside sleeve 18 is consequently rotated in the counter-clockwise direction and the arm 13 is likewise rotated. This arm engages the inner end of the inwardly displaced bar 32 and returns it to normal position. The outer sleeve 15 is unaffected in'this operation and when the bar 32 moved backwardly the dog 82, the face 83 of which was hearing against the portion 82 of the arresting bar 32, moves slightly, bringing the efiective end of the dog 82 into the recess 88 of the arresting bar 32. If more than one bar 32 has been displaced inwardly the bar 11 remains in elevated position and the dogs. 82 remain in the radial direction they occupy in Figs. 12 and 13. If the last displaced bar 32 has been returned to its initial position, as shown in Fig. 13, the bar 11 drops downwardly and the dogs 82 tend to move towards the position shown in Fig.

hand side of the main; frame member 43 (see bearings (not shown) At its upper end the shaft 84 is provided with a worm 88 which meshes with a worm gear 88. Theworm gear is hollow, comprising two complementary portions, one of which has a bearing portion 81, which provides a relatively long bearing surface which'is supported ina stationary bearing 88, as shown'best in Figs. 18 and 19. The stationary bearing plate 88 is mounted in a plate 88 which is supported from the frame member 43 with the aid of projections I88 which maintains the plate 88 in parallel spaced relation to the frame member 43. Upon the outer side of the plate 88 aremounted hollow polished contact members-l8l.

A tubular member I82 extends freely through the bearing portion 81 of the pinion 88 and through an opening I83 in the wall of the pinion opposite the bearing member 81. A rod I84 extends through the hollow pinion 88. This rod passes through an eye I88 of a spring member I 88 (Fig. 22) located within the pinion 88. The spring member comprises two convolutions I81 which extend substantially completely around the-sleeve I 82. The extremities I88 of the spring member I88 are turned radially inwardly and are located in openings I88 in the sleeve I82. Thus, while the sleeve" I82 may move axially within pinion 88 to a limited extent, these two elements are operatively kept together so that the sleeve I82 may be rotated in either direction by'the pinion 88 through the resilient connection I88. Flexibility is. however, provided between the pinion 88 and the sleeve I82, so that any vibration or irregular torsional'movements are not transmitted except through the resilient connection. The face of the pinion 88 opposite the bearing member 81 bears against a thrust bearing II8 mounted'in the plate 43. A pinion III is rotatably mounted within this hearing and one of its faces is pressed towards the side of the pinion 88 by means of a spring II2. This spring abuts a ring II 3 carried by the sleeve I82.

The turntable member 49 is mounted on the right-hand side of the sleeve I82 and when the sleeve I82 is free to move to the left under the influence of the spring I I2, the turntable member 48 is retracted from its operating position as shown in Fig. 18 to the position shown in Fig. 19, in which the member 48 is drawn to the lefthand side, beyond the record contact members I8I. In alignment with the turntable element 48 is the outer turntable element 88, which comprises a central stem portion II4 which is rotatably mounted in a bushing H5 in which it is held by suitable means, for example, by means of an expanded'split ring H8.

The bearing H5 is rigidly mounted in an arm II1 which extends in substantial horizontal direction towards the rear of the machine (see Fig. 1). This arm is of sufficient length to provide clearance of the records II8 when moved into playing. position and the turntable element 58 thereon defines the record playing position.

' The rearward end of the arm H1 is turned inturntable element 49 upon the turntable element 50, during record playing, is communicated by the stemportion II4 of the turntable element 50 to a ball II9 which bears against a hardened plate I20 in the bottom of the bearing member II5.

A pin I2I, which is the centering pin adapted to extend through the central opening of a record, is slidably mounted within the sleeve I02. This pin carries at its left-hand end a cup member I22. A helical spring I23 abuts against the left-hand end of the sleeve I02 and against the interior of the cup member I22. The cup I22 is engaged by a lever I24 which will be hereinafter more particularly described. It is suflicient here to say that when the lever I24 is retracted as shown in Fig. 19, the springs H2 and I23 are extended. The turn table member 49 is thus retracted away from the turn table member 50 and the pin I2I is also retracted so that its pointed end I25 is drawn into the sleeve I02. The spring I23 is much weaker than the spring II2. Consequently, when the lever I24 is moved towards the turn table members 49 and 50 the spring I23 is first compressed and the pointed end I25 of the pin I 24 is projected towards the turn table member 50 and its apex enters into the cavity I26 in the turn table member 50.

As the lever I24 is further actuated, that is, as it moves in the upper direction as viewed in Figs. 18 and 19, the stronger spring H2 is also compressed and the turn table member 49 is carried towards the turn table member 50 to such an extent that any record located between the turn table members is firmly gripped thereby as shown in Fig. 18.

The left-hand portion of the pinion III which is located on the left-hand side of the frame member 43 meshes with the pinion I21 (see Figs. 5, 16, and 17). The pinion III is splined or keyed to the sleeve I02 so that these two elements rotate together while axial movement of the sleeve is permitted as has just been described. The pinion I2! is mounted on a rod I28 carried by the frame member 43. The pinion I2! is integral with a small pinion I29. The pinion I29 meshes with the pinion I30 which is integrally mounted on a hub member I3I (Fig. 16), which in turn is mounted for free rotation on a shaft I32 carried by the frame member 43. The hub member I 3I rigidly carries a notched wheel I33. The notched wheel I33 consequently rotates continuously when the motor 42 is operating.

The pinion I30 also meshes with a pinion I34 which is provided with a relatively large hub I35 whereby it is rotatably mounted on a sleeve I36 rigidly carried by the main frame member 43. A hub I3! is mounted on the shaft I32 alongside the hub I 3I (see Fig. 16). Rigidly mounted on the hub I31 are a disc I38. a cam I39 and a further cam I40. The disc I38 is cut away as indicated at I4l (see Figs. 2 and Adjacent the flattened part Hi the disc I39 has pivoted thereto a dog I 42 which is located on the righthand s de of the disc I30 and is biased inwardly, so that its detent I43 engages the notched wheel I33. When this occurs the disc I38 is positively driven by the motor and consequently the cams I39 and I40 are rotated simultaneously with the disc I38.

8 The hub I35 of the pinion I34 is provided on opposite sides with recesses I44 which are flared in the outward direction. Also mounted on the sleeve I36 is a collar I45 which has camlike projections I46 complementary to the recesses I44. 75

The collar I45 is provided with a radially projecting pin I41. The collar I45 is normally biased towards the hub I35 of the pinion I34 by a coil spring I48 which extends around the free end of the sleeve I36 and is received in a recess I49 in a pulley I50. This pulley is rigidly mounted on the end of the shaft I5I. which is free. to rotate and slide endwise in the sleeve I36. The pulley I50 is maintained in position by means of an arm I53 which bears against a ball I54 located in a central recess in the end of the shaft I5I. The belt 58 previously referred toextends over the pulley I 50. g

The pulley I50 is provided with one or more pins I55 which are directed towards the collar I45 and are so located that when the pulley I50 is forced inwardly by the arm I53, the pin I41 engages one of the pins I55 and drives the pulley I50. When the pulley I50 is prevented from rotation and the collar I45 is likewise held against rotation, then continued operation of the pinion I34 has the effect of moving the collar I45 to the right as viewed in Fig. 16, owing to the cooperation between the sloping sides of the recesses I44 and the corresponding projections I46. It may here be noted that the pulley I 50 and the sleeve I45 become held against rotation when the magazine is arrested by the engagement of one of the dogs 82 with one of the bars 32. k

The result of the outward movement of the collar I45, that is the movement to the right as viewed in Fig. 16, is that the arm I53. is moved outwardly with results which will hereinafter become more fully understood in the light of the description of the operation of the machine which is hereinafter set forth. The arm I53 is one arm of a bell crank lever I56 which is pivotally mounted on base 40 by means of a screw I51. A spring I 58 (see particularly Figs. 5 and 6) tends to move the arm I53 inwardly as viewed in Fig. 16. The other arm I53 of the bell crank lever I56 en ges the lower arm of a lever I 59 pivoted at I60 on the frame member 43. The upper end of the lever I59 is pressed by the spring I58 against the periphery of the disc I38.

When the flattened portion I 4| of the disc I38 arrives in contact with the upper end of the lever I59, that upper end engages the tail of the dog I 42 and withdraws its detent I43 out of contact with the notched wheel I33. When that occurs the rotation of the cams I39 and I 40 is discon- I tinued. The movement of the upper end of the lever I59 to the left as viewed in Fig. 2 rotates the bell crank lever I56 in the clockwise direction as viewed in plan Fig. 5. The resulting inward movement of the arm I53 moves the pulley I50 to the left as viewed in Fig. 16, bringing the pin I4'I into engagement with one of the pins I55. Consequently the belt 58 is driven and the magazine translates until it is arrested in the manner 4 described above. When that occurs the projection I46 effects the movement of the arm I53 to the right as viewed in Fig. 16, and this, as has just been described, results in clockwise rotation of the lever I59. This movement of the lever I59 releases the tail of the dog I42 and the detent of this dog engages the notched wheel I33 so that rotation of the cams I39 and I 40 is begun, As will hereinafter be more fully explained. these 0 cams rotate for approximately one-half revolution and they are arrested, in the position in which they are shown in Fig. 2, during the playing of a recording.

The lever I24 is pivotallymounted on a bracket I carried by the main frame member 43 (see Figs. 2, 5, and 6). The lever I24 carrles'a. projectingarm I62 which is engaged by a spring I63 so as to compress the springs I23 and H2 and force the turn table spindle I2I and the turn table member 49 into record engaging position. The upper side of the arm I62 is engaged by an arm I64 of a three-armed member I65 which is pivotally mounted on a shaft I66. Another arm I61 of the three-armed member I65 bears against the underside of a projecting shoulder I68 of an arm I69. This arm is pivotally mounted on a bracket I10 on the frame member 43 and it is biased against the arml61 by a spring I". The third arm I12 of the three-armed member I65 carries a roller I13 which is adapted to cooperate with the cam I40.

It is to be noted that the roller I13 and the cam have the relation shown in Fig. 2 during a record playing and the relation shown in Fig. 6 when the record is returned to the magazine. It will be noted that in both cases the roller I13 is substantially symmetrical with respect to the cam I40. The result of this relation is that the threearmed member I65 is subjected to substantially the same movement during any consecutive half revolution of the cam, irrespective of the direction in which the cam is turning. It is to be noted that the same fact obtains between the roller I14 of the arm I15, which cooperates with the cam I 39 (see also Figs. 2, 5, and 6).

The arm I15 is integral with the arm I16, both being pivotally mounted by means of a pin I11 on the main frame member 43. The arm I16 is provided adjacent its end with a slot I18. This slot receives a pin I19 carried by an arm I80 which is rigidly secured to a shaft I8I which extends through the main frame member 43 and is carried by a bearing I82 on the right side thereof (see Figs. 1 and 3). 0n the shaft III is mounted the record removing arm 89 and a record returning arm I83. These arms are in longitudinal alignment and operate in the record playing position which is defined by the turntable elements 49 and 50.

The shaft I 8I is biased by a. spring I84 so that the roller I14 tends always to remain in contact with the cam I39. When the roller I14 rolls down the fall on the cam I39, the spring I84 is sufficiently strong to rotate the record retuming arm I 83 in the clockwise direction as viewed in Fig. 2 and return the played record to the magazine. The arm 89 normally, that is at the end of playing and the return of the record to the magazine, occupies the position shown in dotted lines in Fig. 2. For this purpose the arm 89 extends into a position immediately above the frame member 44 and immediately below the records H8 in the magazine, that is the portion of the arm 89 adjacent the magazine enters this magazine between the rear rod 46 and the rear edge of thechannel 44, andhas sumcient space between these elements to move from the dotted to full line position shown in Fig. 2.

When the arm 89 is in the dotted line position shown in Fig. 2, the arm I83 extends in close propinquity to the rear curve of the aligned reccord in the magazine (see also Fig. 6). As the cam I39 makes a one-half revolution, the roller I14 moves outwardly thereon to a position similar to that shown in Fig. 2. Consequently, the arm 89 swings from its dotted line position in Fig. 2 to its full line position in that figure. Adjacent the free end the arm 89 is provided with a record-gripping formation. The record rolls over the rear rod 46, or rather over one of the spacer time sufllcient to allow the record to rotate freely without contacting any part of the arm I83. or of the magazine. When the record is played the centering pin I2I and the turn table element 49 are retracted into their positions shown in Fig. 19. Consequently, the record which was held between the tum table elements 49 and 50 drops I slightly coming into contact with one of the spacing elements 48 of the magazine and the arm I83.

Thereafter the arms I 83 and 89 rotate in the clockwise direction as viewed in Fig. 6, returning the played record to the magazine. It is to be noted that after the record is returned the contact member 88 on the arm 89 engages the bar 68 in the manner and with the results hereinbe fore described.

The player arm, or tone arm I85 is supported in a horizontal bearing I86 (see particularly Figs. 1, 20, and 21). This bearing may be in the form of a sleeve including anti-friction ball bearings I81 which provide for the very ready movement of the sleeve I 88. The sleeve I 88 is held against removal from the bearing I86 by means of a flange I89 at one end and a removable thrust bearing element I90 which is rigidly secured to the other end by means of a nut I99.

The sleeve I 88 rigidly carries a horseshoe bracket I9I. A shaft I92 extends through the sleeve I88 and through a bevel gear, I93 which is located at the side of .the bracket I9I remote from the bearing I86. The shaft I92 is keyed to the bevel gear I93 so that relative sliding movement is permitted between these elements, while the shaft I92 is enabled to drive the bevel gear I93. Between the bevel gear I 93 and the side of the bracket I9I adjacent the bearing I86, the shaft I92 rigidly carries a cam member I94 in the form of a tapering collar rigidly mounted to the shaft -I92 with the aid of a set screw. Beyond the collar I90 the shaft I92-is keyed to a pinion I95. This pinion is maintained against the left-hand end of the sleeve I88 by means of a spring I96 which abuts against the pinion I and against a collar I91 mounted onthe shaft I82. The pinion I95 meshes with a sector I98 which is also pivotally mounted on the shaft I66. 6

The bevel gear I93 meshes with a bevel gear 200 which is integral with the sleeve 20I. sleeve is rotatably mounted in a sleeve 202 which is rigidly carried by the horseshoe bracket I9I with its axis at right angles to the shaft I92. Rotatably mounted on the exterior ofthe sleeve 202 is a sleeve 203, fromwhich extends a pair of arms 204 which support the pivot I 86 of the player arm I85. The bracket I9I carries a counterpoise weight I 85 onthe side of the shaft I 92 removed from the player arm I85. The counterpoise I85 is of such mass that it balances the.

This

arm about the axis provided by the sleeve 202 Is limited to 180, the pin 205 engaging the sleeve 202 at the ends of the slot 208 so as to direct the needle 201 of the pickup 208 towards one side of the record I I8 in playing position between the turntable elements 49 and 50, or towards the other side of the record. I v

A pin 209 is slidably located within the sleeve I. The player arm I85 rigidly carries a short arm 2I0 which extends inwardly-over the'outer end of the pin 209. A spring 2I0'a biases the arm 2I0 towards the pin 209 and consequently causes the pickup needle to bear against the record being played with a certain constant pressure.

The inner end of the pin 209 is adapted to be engaged by the cam member I94 when the shaft I92 is displaced in the upward direction as viewed in Fig. 20. It will readily be understood that when the shaft is thus displaced the pin 209 is moved to the right as viewed in that figure and the arm 2I0 is moved in similar direction, as shown in Fig. 21. Consequently, the player arm I85 is moved away from the record and this occurs irrespective of the side of the record with which the needle 20! is engaging.

Adjacent the bearing I88 the frame member 43 carries an enlargement 2 which is provided with a bore 2I2 which is parallel to the shaft I92. The bore 2I2 is provided with a shoulder 2I3 at its end adjacent the horseshoe bracket I9I. A coil spring 2I4 bears against the shoulder 2I3 and against the shoulder formed on a plug 2I5 which is slidably mounted within the bore 2I2. The plug 2I5 is provided with a stepped bore 2I8 for the reception of a pin 2" which has a sharp point normally projecting from one end of the plug 2I5. The pin 2I'I has a head 2I8 which is located in the larger part of the bore 2I6 and normally is pressed against a shoulder in the bore by means of a spring 2I9. The spring 2I9 is held compressed by a rod 220 which is secured into the larger end of the bore 2I6.

It may here be noted that the shaft I92 and the plug 2I5 are displaced from their normal positions shown in Fig. 20 into the positions shown in Fig. 21 by means of the arm I89; It will be noted that when that displacement occurs the player arm I85 is moved away from the record. At the same time the pin 2I1 is brought into contact with the horseshoe bracket I 9|. It may be here noted that the bracket I9I is relatively broad and it is adapted to overlie the pin 2I'I in all its operative positions.

The engagement of the point of the pin 2I I with the bracket I9I causes only a slight frictional force upon the bracket I9I. It may here be noted that the bracket I9I is moved by the sector I98 before the playing of a record.

If the recording on the left-hand side of a moord is played and a recording on the left-hand side of a record is to be played again, the movement of the sector I98 is such that the player arm.

is merely returned to initial playing position, that The sector I 98 is moved when the arm I88 is in the relation shown in Fig. 21. Consequently, the sector movement occurs when the player arm I is raised from the record and when the pin 2II is forced against the bracket I9I. When the sector is-moved the friction between the gears I93 and 200 is such that the player arm assembly moves as a whole and no rotation of the player arm relative to the sleeve 202 occurs. When, however, the pin 2I"I enters the recess 22I on the bracket I9I, there'is considerable resistance to the free movement of the player arm assembly and this resistance is sufficient to hold the assembly in definite position determined by the location of the recess 22I until the bevel gear I93 has driven the bevel gear 200 and effected the which is necessary for changing from playing left-hand recordings to right-hand recordings or vice versa.

The recess 22I is located on the bracket I9I, so that the arrestment of the player arm and the arcuate movement of the player arm occurs when the player arm is approximately at its highest position. It may also be noted that the arcuate path of the pickup is in the upward direction around the record playing position so that the movements of the record and the tuming of the player arm may be effected simultaneously,

Referring more particularly to Figs. 21, 5, 6, and

7, it may be seen that sector I98 carries two integral arms 222 and 223 which are adapted to be engaged by a head 224, located between these arms, which head is carried at one end of a bell crank lever 225 which is pivotally mounted on a rod 228 carried by the frame member 43 by means of apost 221.

The end of the lever 225 remote from the head 224 is adapted to be engaged by one or the other of twopins 228 and 229 (Fig. 7) which are carried by the disc I 38. The portion of the lever 225 remote from the head 224 is normally maintained substantially radial with respect to the axis of the cams I39 and I40. This result may suitably be attainedby means of a spring 225 which is securedto a lug integral with the lever 225 and also secured to the frame member 43.

When the disc I38 rotates in the counter- I clockwise direction, as viewed in Fig. '7, the pin is moving in the reverse direction, to its course during the previous playing. If right-hand recording is followed by another right-hand recording, the same result is attained, the movement being, of course, in the opposite direction, as is necessary from the fact that the player arm is located on the opposite side'of the record. When, however, a leftehand recording follows a right-hand recording, or a right-hand recording follows a left-hand recording, it is necessary for the player arm to rotate on the sleeve 202 through 180.

228 engages the lever 225 so as to swing it in clockwisedirection. Consequently, the head 224 engages the arm 222 and swings the sector I98 downwardly, thus carrying the player arm downwardly into position for playing the right-hand side of the record. When, however, the disc I 38 rotates in the clockwise direction, as viewed in Fig. 7, the pin 229 engages the lever 225 and swings the sector I98 upwardly. This upward movement carries the player arm upwardly. It is to be noted that the pins 228 and 229 are normally clear of the lever 225, and consequently during playing of a record the player arm and the sector I98 move freely and together.

It is advisable that the initial playing position of the player arm should be capable of adjustment with considerable accuracy, The player arm is arrested at initial playing position by the engagement of a pin 230, carried by the frame member 43 with one or another of two stops 23I' which are pivotally mounted on the horseshoe bracket I9I as shown in Fig. 14. The stops 23I are pivotally mounted on this bracket (see Figs. 20 and 21) so that portions ,thereof project beyond the bracket into alignment with the pin 230. The stops 23! abut against set position playing position., If'the player arm is carried past initial playing position, it is returned to the correct position by the pin 230 engaging one of the stops 23I which are biased against the screws 232 by the springs 23I. Thus the player arm is returned to the correct initial playing position by the action of the springs 23I' after the bell crank lever 225 has been returned to its neutral position by the spring 225, leaving the sector I98 free.

Also mounted on the shaft I66 are two levers 233 and 234. The levers 233 and 234 are oppositely directed. At adjacent ends they are provided with detent formations: 235 and 236 which are directed towards each other and which are located in cooperative relation with the periphery of the bearing element I90 which is rigidly secured to the sleeve I98, so that the bearing element I90 moves progressively with the player arm I85 as the latter is moved around the axis provided by the bearing I86.

The detents 235 and 236 are held against the periphery of the element I90 by means of a spring 231 which extends between the two levers 233 and 234, and holds both detents at all times in contact with the element I90. The element I90 is rigidly secured to the sleeve I88 so that it always rotates with the player arm I85 as that arm moves over the face of a' record in playing position. The element I90 is provided with a peripheral recess 238 in alignment with the detents 235 and 236. The detents 235 and 236 are raised out of the recess on to the periphery of the member I90 on mere rotation of the element I90. When'the player arm I85 is in the position shown in full lines in Fig. 5, that is, the initial position for playing the left-hand side of a record, then the detent 235 is located within the recess 238 and the detent 235 is riding on the periph ery of the element I90. I

During playing the player arm I85 moves downwardly over the record and when it reaches a position corresponding to the dotted line position in Fig. 5, that is, after the record has been played, the member I90 has rotated in the clockwise direction, as viewed in Fig. 5, suillciently to permit the detent 236 to drop into the recess 238 as shown in Figs. 6, '7 and 8. When the righthand side of a record is being played, for example, as shown in Fig. 2, the detent 236 is located in the recess 238 and the detent 235 is riding on the periphery of the element I90. As the record is played, the element I90 rotates in counterclockwise direction, as viewed in Fig. 2, until, at a point where the record has been played, the detent 235 also drops into the recess 238.

When the detent 236 is riding on ,the periphery of the member I90, the opposite end of the lever 234 is in alignment with the end 239 of a hook member 240 which is suspended from the rod 226 of the detents are located in the recess 239 and the hook 240 is free to swing to the left, as viewed in Figs. ,6, '7 and 8.

It may be noted that the hook 240 is located to the right of the disc I38, and is free to hang downwardly behind this disc as shown in Figs. 8, 7 and 8. The hoolg 240 is, however, in alignment with the dog I42 carried by the disc I38. When the cam shaft rotates into the position shown in Figs. 2 and 5, the hook 240 engages the dog I42 and raises the detent I43 thereof away tends to hold its detent I43 in contact with Consequently, the operations of returning the V record, moving the magazine to another position, etc., are resumed.

It will be noted that the phonograph will operate automatically and continuously as long as the motor 42 is driven. If any of the bars 32 are pressed inwardly, the corresponding recordings will be played and the corresponding bars will be returned to normal position. If none of the bars 32 are pressed inwardly, or after all the.

bars have been returned outwardly, the machine functions to play the recordings one after another automatically until the motor 42 is stopped.

The machine is particularly well adapted for coin operation, the coin control mechanism merely controlling the operation of the motor.

The coin control mechanism may suitably be mounted on the right-hand side of the frame member 43, being located inwardly of the record playing position. This mechanism is best shown in Fig. 4 and may comprise a coin chute 2, which extends from an upper part of the cabinet and terminates in a suitable cash box (not shown). The coin chute 24I is provided at a suitable point with a slot 242, through which extends a pin 243. The pin 243 is carried by a lever 244 which is pivotally mounted at 245 on the frame member 43. The pin 243 is located in the path of a coin 246 passing down the coin chute 24I. The lever 244 is adapted to cooperate with one leaf m of a leaf switch m bring it into contact with the other leaf 249 when the pin 243 is hit by a falling coin.

as best seen in Fig. 5. When, however, the detent 252 which is pivotally mounted on the frame member 43. A spring 253 connected to the lever 252 normally moves the armature 25I out-. wardly with respect to the solenoid 250. This outward movement is limited by a stop 254. Upon one end of the lever 252 is pivotally mounted a dog 255. This dog is normally held in its full line position, shown in Fig. 4. by means 01' a spring 288 and abutments 256' on the dog 2 and on the lever 252. Consequently, the dog is free for limited movement in the counterclockwise direction as viewed in Fig. ,4, but is definitely held against movement in the opposite direction. The dog 258 is adapted to cooperate with the tooth on a ratchet wheel 25! which is rotatably mounted on the frame member 48.

The ratchet wheel 25! is biased-for movement in the counter-clockwise direction as viewed in Fig. 4 by means or the spring 258. By rotation of the ratchet wheel 25! in this direction is normally prevented by means of the detent 258 of an escapement member 2. This escapement member has a second detent 2" so arranged that when the escapement member 268 is oscillated from its full line position under the influence of the spring 262, the ratchet wheel 251 will rotate one tooth in the counter-clockwise direction.

The ratchet wheel 251 carries a projecting pin 253 which is adapted to cooperate With the arm 2 of the micrometer switch 285. When the pin 263 moves upwardly from its position shown infulllinesinFig.4toitspositionshownin dotted lines it raises the arm 26c from the stop 266 and efiects the opening of the switch 265. This switch controls the supply of current to the motor 42 and consequently this movement of the arm 26d terminates the operation of the machine.

The escapement member 266 has pivotally mounted thereon a dog 25? which is held against an abutment 268 on the escapement member 260 by means of a tension spring 269 carried by the dog 26?. The dog 26! is adapted to be actuated by a short arm 210 which is rigidly mounted on the shaft lBi upon which are rigidly mounted the record moving arms 89 and I83.

' When these arms are moved in the clockwise direction, as viewed in Fig. 4, in order to remove a record from the magazine to the turn table elements for playing. the arm 278 merely displaces the dog 26? relative to the escapement member 280 without actuating the escapement 45 member.

When, however, the arms 89 and I83 have reached the final stage of returning the played record to the magazine, the arm 2'"! rotates the dog 28] in the clockwise direction, as viewed in Fig. 4. This movement carries the escapement member 260 with it owing to the engagement of the dog 28! with the abutment 268.- Consequently, the detent 259 is withdrawn from the ratchet wheel 25?, but the detent 26! is first interposed in the bath of one of the teeth of the ratchet wheel. Consequently, the ratchetwheel is able to rotate in counter-clockwise direction onb part of one tooth space. The continued movement of the arms 88 and I83 moves the arm wardly from the rotating the ratchet wheel 25! one tooth in clock. wise direction. The ratchet wheel 25! is held in that position, which is the position shown in Fig. 4, by the detent 258 on the escapement member 260. If a plurality of coins is inserted in the chute 2H, the'ratchet wheel 251 isdisplaced; by a corresponding number of teeth. When the first coin is inserted the pin 263 moves away from the switch arm 284 and the switch 265 is closed. Consequently, the motor 42 starts operating. This motor operates in one direction or in the reverse direction, depending upon the position of the reversing switch 84. If this switch is snapped in the position shown in full lines in Fig. 15, the motordrives the turn table element 48 in the counter-clockwise direction as viewed in Fig. 2, and consequently the machine will operateto play the right-hand side of a record, as viewed from the front of the machine, that is the side which carries the selector buttons 3|. This is the left-hand side of the-record as viewed from the rear, as in Fig. 3. It may here be interposed that if the switch 66 were snapped in the opposite direction, the direction of rota= tion of the turn table member as would also be reversed.

When the machine ceases playing the lever IE9 is located in the recess wt of the disc I38 and returns the dog M2 out ofengagement with the notched wheel I33. Consequently, the bell crank lever I56 is swung by the spring H53 in such manner that it pushes the pulley I50 inposition shown in 16. In that inward position the pins I55 of the pulley are adapted to be operatively engaged by the pin it! ofthe sleeve M5, and the pulley I50 is driven in the clockwise direction as viewed in Fig. 2. The screw 55 is therefore driven in counterclockwise direction, as viewed in Fig. 2, with the result that the magazine moves to the left. During this movement the left-hand dog 82 is operative and the right-hand dog 82 is inoperative, slipping over any of the bars 32 which it may engage. r

If any of the bars 32 have been pushed inwardly the rail I1 is elevated as shown in Figs. 12 and 13. Consequen the dogs 82 are swung round from their position shown in Fig. 10 to their position shown in Figs. 12 and 13. In this relation the dogs 82 avoid contact with the bars 32 which have not been pushed inwardly, but will engage the first bar of the left half series of rods 32 which have been pushed in, as best seen in Figs. 12. and 13.

55 In 1 the magazine is shown arrested by 210 so that the escapement member 280 may resume its full line position as shown in Fig. 4.

Whenthisoccursthelastpartoftheone tooth movement of the ratchet wheel 25! is completed. In the event that the pin 263 was in the position shown in full lines in Fig. 4, this last partial movement of the ratchet wheel 25'! brings the pin 263 into the dotted line position shown in this figure and effects the opening of the switch 265.

The operation of the phonograph will now be briefly described. A coin 245 is passed down the chute 2, closing the switch 288 and energizing the solenoid 259. Consequently, the-dog .255 is moved into its dotted line position in Fig. 4,

engagement of the operative dog 82, that is the left-hand dog, with the inner first rod of the left-hand series, which rod has been pushed inwardly. When the left-hand dog 82 1 engages this bar 32, the left-hand assembly which includes the left-hand dog 82 and associated sleeves l5 and I0, is arrested and the magazine continues to move until the sleeve 72 abuts against its sleeve 10. The relative movement thus provided between .theleft and right-hand dogs 82 insures that the left-hand rod return arm I3 is in alignment with the arresting bar 32, whereas, the right-hand return arm 13 is out of alignment with all the bars 32.

It may here be noted that if none of the rods was pushed inwardly, the rail T! would be in the position shown in Figs. 10 and 11, and the lefthand dog 82 would have engaged the next adiacent bar 32,'bringing the magazine to a stop in the manner previously described.

' the drive of the pulley I it is overloaded. Con- -sequently, the wedge shaped formation I44 of the hub of the pinion I34 forces the collar I48 and the ball I54 outwardly, thus swinging the bell crank lever I" in counter-clockwise direction as viewed in plan. This movement withdraws the lever I59 from the dog I42; so that the latter engages the notched wheel Ill and the cams I32 and I 40 start to rotatein the counter-clockwise direction, as viewed in Fig.2. This rotation removes the notch I4I away from the lever I50, and the latter, owing to its engagement with the periphery of the disc Ill, holds the arm I53 in an outward position against the action of the spring I58. Consequently, the sleeve I45 moves to the left when the recess I44 is again presented to its wedge-shaped projection I46, the pins II! of the pulley I50 being kept away from the pin I" by the spring I48. This relation persists until the recess I is again brought into cooperative relation with the lever I59, after the record has been played and returned to the magazine. When the recess I does arrive at its position, shown in Figs. 6 and 7, the pulley I50 moves inwardly movement of the bracket is resisted by the pin 2" in the recess 22I, the downward movement of the sector rotates the. gear .Ilt in clockwise -di: rection asviewed in Fig. and the gear!" is rotated in counter-clockwise direction, as viewed from the left in Fig. 20. Consequently,.'the player arm is rotated around the axis-provided by the sleeve 242 from'the left-hand side of the record playing position tothe right-handside thereof, as shown in- Figs. and 21.

When the pin 204 reaches 2" in the vsleeve 2",. further rotation of-the gears I and 2III-is rendered impossible. Thereupon, the force supplied by the sector I von the pinion I" rotates the bracket IOI so as to move thepin 2Il out of the recess 22I and bring the player arm to .initial playing position for the right-hand side of the record, a shown inFig. 2.

When about to play. a recording on the leftzo hand side of a record after playing a recording on again, ready to resume the translation of the magazine.

If the machine last played the right-hand side of a record, the player arm will be left in initial position for the playing of the right-hand side of a record, as is shown in Fig. 2. The reason for this is that two pins 228 and 229 are provided for locating the player arm. Two such pins are provided because the disc carrying these pins may start moving in one direction or the other direction. The result is that the player arm may be thrust to initial position by -one pin during the first half rotation of the cam shaft, and is returned to the same initial position during the second half rotation of the cam-shaft. For the same reason, the player arm will be located at initial playing position for a left-hand recording, if a left-hand recording was last played.

The cams I39 and I4! are initially in the positions shown in Figs. 6. and '7. When they start moving in counter-clockwise direction, the pin 228 engages the lower end of the lever 225, throwing it clockwise. The lever 225 engages the arm 222 of the sector I98 and throws the sector counter-clockwise, thus rotatingthe pinion 238 clockwise, as viewed in Fig. '7.

' The shaft I92 on which the pinion I95 is mounted and also the bevel gear splined to the shaft rotate in similar direction. If the player arm is merely being moved back to initial playing on the same side it played before, the sector I does not need to be displaced very much, and in this case the gears I93 and 200 are not moved relative to the bracket ISI and the player arm assembly generally.

When, however, theplayer arm I85 is changing over to play the right-hand side of a record when it last played a left-hand side record, then the player arm has to be transported from its position in Fig. 5 to its position in Fig. 2 and it must be rotated about .the axis provided by the sleeve 202. For this purpose the sector is thrown through a very wide angle, that is, from its position shown in Fig. 5 to its position shown in Fig. 2. In the initial part of this movement the point of the pin 2II enters the recess 22I in the surface of the bracket Hi, this movement occurring when the arm I69 is in the position shownin Fig. 21.

the right-hand side of a record, the procedure is exactly opposite. In both cases, however, the player arm turns in the same are which extends upwardlyaround the position occupied by the upper edge of a record on the turntable. It is to be noted that the levers 233 and 234 operate automatically. Thus,-when the player arm I" is in the full line position shown in Fig. 5, the detent 235 is in the recess 23!, while the detent 238 is riding on the periphery of the member I.

When, however, the player arm moves into the dotted line position shown in Fig. 5, which corresponds to the end of the playing of a recording on the left-hand side of a record, the detent. drops into the recess 23! with the results, previously described, of starting movement of the cams I39 and I40 from their position show? in Fig. 5, to their position shown in Fig. 6.

When the player arm is reversed from its position as shown in Fig. 5 and is carried downwardly, in the manner previously described, the detent 2" remains in the recess 2" and likewise does the detent 235 until the position of the end of playing of a right-hand recording is reached. Thereupon the detent 225 rises out of the recess 23! and below that point this detent rides on the surface of the member m.

It merely remains to draw attention to the coordination of the cam actuated members which effect the movements of the record from and to the magazine, the means for controlling the movable turntable element and its centering pin and the means for moving the needle away from the record.

The cams I39 and I40 are initially in the position shown in Fig. 6. It is to be noted that these cams are symmetrical with respect to the elements which engage them. Consequently it does not matter, as far as the mechanisms just mentioned are concerned, whether the cams ro- When the sector I98 is moved downwardly, the 76 tate in one direction or the other. It is to be noted'that the three-armed member I64, I61, and I12 is rotated to its greatest extent in the clockwise direction. Consequently, thetumtable element 49 and its centering pin I2I are retracted in the manner shown in Fig. 19 and consequently the needle is raised away from the record position and this is true irrespective of the position of the needle on one side or on the other side of the record playing position.

The lever I1! is on the lowest point of the cam I3! and-consequently the levers 89 and Ill have the positions shownin Fig. 6 When the cams I39 and I40 start moving from the posia. emi'cr the slot tion shown in Fig. 6, the arms 89 and I83 start Swinging to the left as viewed in that figure.

The swinging of the player arm I85, by the pin 228 or 229, if that is necessary, is effected as drops on to the arm I83, the roller I13 of the arm I12 moves over a fall on the cam I49, so that the three arms are permitted to rotate in counterclockwise direction as viewed in Fig. 2. Consequently, the arm I24 moves inwardly, first projecting the pointed end I25 of the center pin I2I' through the central opening in the record, thereby raising the record from the bar 46 and from the bar I83, and thus moving the turn table member 49 inwardly so as to clutch the record between the turn table members 49 and 59. At the same time the downward'movement of the arm I61 allows the arm I69 to move outwardly away from the shaft I92. Consequently, the spring I96 moves the shaft I92 from the position shown in Fig. 21 to the position shown in 20. When that movement is effected, thespring 2I9a moves the player arm towards the record so as to apply the needle thereto with suflicient resilience to enable it to properly cooperate with the sound groove on the record.

When these movements have been completed the cams I39 and I40 are in the position shown in Figs. 5 and 2. At this time one of the levers 233 or 234 is located opposite the end 239 of the hook member 249. This hook member is engaged by the tail of the dog I42 and is swung against said lever which serves as an abutment for the hook 249 which acts to elevate the detent I43 out of engagement with the spur wheel I33. The cams I39 and I49 are now arrested and they remain in that condition until the recording has been played.

When the playing of the record is completed the lever 233 or 234, as the case may be, clears the end 239 of the hook member 249. The dog I42 is released and the cams begin rotation and return to the position shown in Figs. 6 and 7. During this semi-rotation the reverse movements occur, that is, the shaft I92 moves inwardly and raises the needle from the record. The turntable element 49 is retracted, likewise the centering pin I2I, and the played record is allowed to descend on to the arm I83. The arm I83 then returns the played record 'to the magazine.

When the arm 89 approaches its initial position, that is, its position shown in dotted lines Fig. 2, the projection 88 at the end thereof engages the bar 68 and allows the eiiective dog 82 to move to some extent past the bar 32 which arrested it, thus enabling the magazine to resume its movement during the next cycle. Also at the end of the operation of returning the played record to the magazine, the escapement member 260 is oscillated in the manner previously described. If the pin 263 occupied the position shown in Fig. 4 during the playing of the record, this pin is now moved to its dotted line position in Fig. 4, and the switch 265 is opened and the motor 42 stops. r

If, however, a. plurality of coins had been originally inserted, the pin 263 will occupy a position displaced from its full line position in Fig. 4 in .the clockwise direction. If this is the case, then the ratchet'wheel 251. will merely rotate the distance of one tooth without affecting the switch 265. Consequently, the motor 42 will keep rum .azine by means of washers 69.

ning and the cycle will be repeated with successive records until eventually the pin 263 is moved to its dotted line, position in Fig. 4 and the switch 266 is opened. It will readily be'understood from the earlier description that the successive records thus played are thus corresponding to the bars 32 which have been pressed inwardly, if any. If none of the bars 32 has been pressed inwardly, the machine will play the same sides of successive records in the manner hereinbefore indicated.

The selector mechanism illustrated in Figs. 23 to 29, inclusive, may be used insted of that described in connection with Figs. 9 to 13, inclusive. The two selectors comprise many similar elements which are designated by the same reference numerals as have been employed in the previously described embodiment.

The magazine 39 carries a shaft 61 upon which is pivota-llymounteda bail 68 which is normally maintained in the position shown in Fig. 24 by means of springs 9I. 'The ends of the bail 68 are separated from the end walls 45 of the mag- On the inner side of each end of the ball 68 and slidably mounted on the shaft 61 is a sleeve 19. These sleeves are pressed away from each other by means of a spring 14 so that their remote ends always tend to abut against the ends of the bail 68. The sleeves 19 may be caused to approach each other to a slight extent, the degree of approach being controlled by the spacing sleeve 12, around which the spring 14 is mounted. Adjacent its outermost ends, each sleeve 19 rigidlyjcarries an arm spring 31I which is connected to the magazine and which tends to rotate the sleeve 19 in the clockwise direction, as viewed in Fig. 24. The arm 13 is provided with a shoulder 312 which is adapted to be engaged by the bail 68, when that ball is thrown by the projection 88-on the lever .89 in the counter-clockwise direction, as shown in Fig. 25. This occurs when a record has been returned to the magazine. The arm 13 also carries a shoulder 313 which is adapted to engage one of the detents 314, which will be more fully described. It may, however, be noted that this engagement effects the movement of the detent 314 from its position shown in Fig. 24 into its position shown in Fig. 25.

The sleeve 19 carries a lateral extension 315 on which is rigidly carried a dog 316. Also mounted on this lateral extension is a pivoted dog 311. The dogs 316 and 311 are suitably located together and the latter is pressed downwardly by means of a spring 318 so that it tends 1 to occupy a lower position than does the dog 316.

The-lateral extension 315 is also provided with an abutment 16 which may suitably be an extension of the pivot 01 the dog 311. The abutment 16 is adapted to cooperate with a bar 11. This bar is pivotally mounted by means of end members 19 upon brackets 90 carried on. the frame 36. Through these brackets extends a shaft 19. The shaft 19 has mounted thereon a series of discs 319 corresponding in number to the number of selections or recordings for which the machine is intended. That number is, of course, double the number of the records for which the magazine is intended. Each disc 319 is rotatably mounted on a spacing washer 389 which is supported on the shaft 19. Between adjacent discs 319 and spacing washer's 380 are located discs 38I which effectively space the discs 319, corresponding to the spacing of the records in the magazine. The spacing washers 389 are 13 to which is connected 2..
