T all whom itmay com-em:

Be it known that I, HADWEN SWAIN, a citizen of the United States, residing at San Francisco, in the county of San Francisco, State of California, have invented certain new and useful Improvements in Automatic Phonographs, of which the following is a specification.

This invention relates to an automatic phonograph.

It is the principal object of this invention to provide a phonograph adapted to be actuated to consecutively or selectively play a series of phonograph records.

The invention contemplates the use of a disk magazine which operates in conjunction with a mechanism for selectively removing the disks from the magazine and placing them in playing relation to a reproducing mechanism for consecutive or continuous playing, thereafter restoring the disk to the magazine after the playing operation and discontinuing the operation of the motor by which the entire apparatus is driven. said mechanism also embodying means for automatically adjusting the tone arm to records of varying diameters.

The invention is illustrated by way of example in the accompanying drawings,'in which Fig. 1 is a view in plan disclosing the phonograph case within which is positioned the disk magazine, the reproducer mechanism and the timing apparatus connecting the magazine and said mechanism.

Referring more particularly to the drawings, 10 indicates a case, here shown as rectangular in plan, and within which a phonograph mechanism is positioned. Thls 'case has a bottom wall 11, an intermediate horizontal wall 12 and a cover 13. The major portion of the present mechanism is mounted upon. or suspended from, the intermediate floor 12. Upon this floor is positioned a disk magazine 14, shown in Fig. 1 as describing a sector of a circle and in Fig. 20 as describing a complete circle. This ma azine is formed with a series of spaced gui e fingers 15. having radial faces concentric with the pivot 16.

In register with these fingers are rack slots 17 and 18 which are intended to accommodate records of different diameters. In the resent instance, the slots 17 are provided or ten-inch records and the slots 18 for twelve-inch records. The magazine 14 as ivoted upon the pin 16 mag swing over the fioor 12 and is sup orte thereupon by means of casters 19. he magazine is also formed with a floor 20 upon which. the record disks rest when in register with the fingers 15 and the res ective slots 17 and 18. The forward edge 0 this floor is formed with a vertically extending ledge 21 which is arcuate in plan and forms a barrier for the records 22 when they are carried by the magazine. The pivot pin 16 is articularly shown in Fig. 2 as mounted wit per end of a standard 23. This member is fixed upon the floor 12 and also carries a bearing 24 rotatably supportin the spindle 25 of a turn-table 26, this tab e posed to rotate in a vertical plane. 3

The outer face'of the turn-table is in the same vertical plane with the rotating axis of the magazine and is further in a corres onding relation to an upper disk runway 27 and a lower disk runway 28, as particularly shown in Figs. 11 and 12 of the drawings. The upper runwa is channel-shaped having spaced vertical si es forming a groove along which the disks may ass and b which they are guided. The orward en s of these side plates are cut away to provide clearance for the larger records of the megazine as they swing in relation thereto. he lower runway is also channel-shaped and terminates near the edge of the ledge 21, it being cut away to clear the circumference of the smaller disks and disposed in proper relation to receive either SIZE" of disk as they roll over the ledge 21 and toward the turntable.

The disks are ejected from the magazine and directed along the runways by means of an ejector finger 29, which is arcuate in shape and is fixed to the end of an arm extending from a pivot pin 30. This pin is mounted in suitable brackets in front of the magazine andthus permits the ejector finger 29 to swing verticall and in swingin to engage the rear side 0 the disk involve to lift the disk over the ledge 21, at the same time imparting rotating motion to the same.

This liftin action is produced by a weight 31 suspendec upon a forwardly extending lever arm 32 which is formed integral with the arm of the ejector finger 29 and upon the opposite side of its pivotal center, thereby normally tending to swing the finger upwardly. The action of the weight 31 is resisted by a lifting finger 33 pivoted at 34 and which is formed integralwith a downwardly extending shifting lever 33'. This lever projects through an opening in the floor 12 and is engaged by shifting mechain the up-.

being disnism which will [be hereinafter described, said mechanism acting to'swin the lever and to move the fin r 33 a war ly'beneath the arm 32. An a ditiona .lock finger 35 is disposed alon' ide ofthe ejector finger 29 and is mounted y means of anextension arm 36 to swing around the pivot pin 30. This member has a forward extension which carries a reciprocating lock pin 37 by which the lever arm 32and the entire lever structure 36 may -'be. locked to ether when desired. The lock finger 35 is o shorter length than the ejectorfinger '29 and, as shown in Fig. 2, is striking against a lock bar 38.

' The sha e of the bar 38 is particularly shown in i 1, where it will be seen to posse'ss a straig t shankat the end of-which is an arcuate extension adapted to swing across the path of travel of the finger 35 and to obstruct its movement, when desired. The member 38 is pivoted to a vertical in 38' which extends upwardly along the f rward side of the cabinet 10 and is housed within suitable bearings 40 at its upper and lower ends. This pin carries a shifting fork 41 adapted to engage the shank 42 of a lock pin 43. and to rest between a shoulder upon this pin and a small stop pin extending through the shank 42. In this manner it will be seen that forward or rearward movement of the lock pin 43 will act to rotate the pin 38' and swing the lock bar 38 into or out of its obstructin position.

The s ank 42 of the pin 43 is adapted to register with perforations 44 formed in the outer shell 45 of the magazine, by which action the magazine is locked during the playing operation. Movement of the lock pin 43 is here shown as effected by the co-operative action of a push button 46 and a suitable coin. As shown in Fig. 3 the push button and lock pin are reciprocally mounted within a control case 47 and have complementary slotted portions along their adjacent sides into which a coin may, be placed through the slot 48. When this coin is in position the push button and lock pin will. be temporarily connected and pressure upon the button will force the pin inwardly and cause its shank to pass through the perforation in the shell, at the same time rotating the pin 38'. thus acting to release the finger 35 and to permit the ejector finger 29 to swing upwardly. It is assumed that the pin 37 is locking the two

fingers

29 and 35 to move together when this action takes place. In the event that the pin 37 does not lock these two members the lock bar 38 will have no effect upon the ejector 29 and will cause it to return the record to the turn-table from the magazine after having been played, thus making the device adapted for the continuous playing of dance music. It will be understood that any suitable slot or receptacle may be made a part of the casing 47 to receive the coins.

55, the lower end being pivoted Fixed to the under side of the floor 12 is a hanger 49 which carries a. pivot pin 50 at its lower end. Mounted upon this pivot pin is a record returning arm 51 which extends u wardly through a slot in the

floor

12 and 13 formed with an outer arcuate end adapted to conform to the contour of the record upon the turn table 26. The pivotpin 50 is disused in such position that the arm 51 may have a sweep across the turntable when swinging and will thus engage the record thereon and roll it up the runways which are both inclined downwardly from the magazine and cause it to pass over the ledge 21 to assume its ori inal seated position within the magazine. 'I his swinging action is roduced by an eccentric cam 52, whic is mounted upon a horizontally extending timing shaft 53 driven in a manner which will be hereinafter set forth. The cam 52 is adapted to engage a roller pin 54 which constantly bears upon its outer surface and is disposed above the eccentric. This pin is mounted at the upper end of a pitman rod to a rocker arm 56. The arm 56 is integrally united with the record returning arm 51 and will thus cause this arm to swing as the cam 52 raises the pin 54. This mechanism will restore the record to its original position within the magazine.

The timin shaft 53 carries a splined gear 57 by which it may be rotated. This gear is brought into mesh with a gear 58 fixed upon the turn-table spindle 25 and adapted to rotate therewith. Motion is imparted to the turn-table and its spindle by means of a friction wheel 59 held 'therebeneath and adapted to float as supported u on a. small friction roller 60. The axis of t e roller 59 is carried by swinging arms 61 pivoted at their rear ends to a bracket 62' dependent from the floor 12. The axle of the roller 60 is carried upon a vertically swinging link 62 pivoted to the main floor of the cabinet. This last-named axle also carries a large friction disk 63 in engagement with a driving disk 64 fixed upon the main shaft of a motor 65. Through the medium of this motor and various disks the entire mechanism of the phonograph is actuated and this therefore constitutes the source of power and its transmission mechanism.

The switch circuit controlling the motor is indicated at 66 and is shown as having sliding blades 67 adapted to be reciprocaterl between fingers upon an arm 68. This arm swings substantially vertically and is pivoted to the lower end of a switch control arm 69. The switch control arm extends upwardly through an opening in the floor 12 and is there pivotally supported upon a pin 70 carried in a suitable bracket upon the floor. The upper end of the control 69 supports a stop carrier 71. Fixed by means of apin 72 to the end of the arm 69 is a disk stop 73. This member consists of a shank throu h which the pin extends and at the outer on s of which are two arcuate disk engaging members 74 and 75. These memrs are offset horizontally and stand in concentric relation to the axis of the turn table spindle to coincide with the outer circumferences of the ten and twelve-inch re:- ords, thus causin them to be disposed on arcs of substantia ly five and six-inch radii respectively. The stop carrier 71 is pivoted for vertical swinging movement upon the floor 12 by means of a pin 76, as in Fig. i, which extends through bosses upon the carrier. The arm 69 is pivoted at 70 so that it can swing toward and away from the turntable, theloose joint at 72 permitting this movement. This member allows the entire stop mechanism to swing transversely and to bring the parts 74 and 75 into register with the records of corresponding sizes. Normally the stop is set for 10-inch records and when the lower track 28 is lowered by the action of a 12-inch record the member 74 will move away from,the turn-table, as will be presently described. This swinging action is effected by downward movement of an extension 77 formed as a part of the lower runway 28, it being understood that thisrunway is pivoted at its forward end upon the pivot pin 28'. The extension portion 77 which is forked and engages an inclined shank 78 upon the lower end of the carriage, as particularly shown in Fig. 4, and thereby produces the transverse swinging movement. The depression of the runway 28 and this extension is, of course, effected by the disk passing therealong and is permitted by the release of a mechanism actuated by the larger size records and which will be presently described. It will be noted that the striking of the record against its respective stop shoulder 74. 75 Will swing the arm 69 and will causethc switch contacts to be united, thereby starting the motor.

'A notch 69 is formed in the rear face of the controlling arm 69 and normally supports

levers

79 and 80. These levers stand transversely of the arm 69 and are pivoted upon a shaft 81, the lever 79 being fastened to its shaft, as particularly shown in Fig. 14, while the lever 80 is fixed upon a sleeve 82 carried u on the shaft. The shaft 81 fitted with a s ifting arm 83 at its outer end. This arm is adapted to engage shoulders upon a centering pin 84, as particularly indlcated in Fig. 13, and which reciprocates within a bearing 84'. The centering pin is formed at its forward end with a conical point adapted to enter the opening in the center of 'the record disk, it being understood that this pin reciprocates horizontally toward and away from the turn-table 26 This lever 80 is rovide'd to allow move- 'ment of the repro ucer arm 88. This arm and its mounting are particularly shown in Fi s. 15 and 16 of the drawings where it will be seen to possess a horizontal extension 89 passing to a horn 90. This extension is rotatably supported within a sleeve 91. which allows t etone arm to swing over the face of the turn-table. The extension and the main body of the arm are articulately connected by a pin 92 which allows the vertical arm to swing toward and away from the turn-table. -A weight 93 is mounted upon the arm and oil center from the pin 92 so that the arm may normally swing toward the face of the turn-table. The action of this weight is normally prevented by the locking of the lever 80 within the notch upon the member 69, and when this is released is partially resisted by the escape of air from the cylinder 87 as the piston 86 is forced downwardly. A side view of the weight 93 is more artic ilarly shown in Fig. 15, where it will e seen to be arcuate and concentric with the horizontal axis of the extension 89. This arcuate portion extends rearwardly and may be engaged by a finger 77' upon the extension 77 of the lower runway to swing the tone arm into a position for accommodating the larger size records used in the machine. This weight also counterbalances the tone arm and allows it to traverse the face of the rec- A 0rd disk in a desirable manner, the weight being so distributed so as to give the needle a slight lead toward the center of the record.

In order to normall hold the tone arm in initial playing position for both size records a. stop rack 94 is provided having two notches on its face. A V-shaped projection 68 is mounted upon the tone arm and is adapted to register with either of these notches. The stop arm extends parallel to the face of the turn table and may be relieved from supporting the upper part of the tone arm by the downward swinging of the lever 80 as it rotates the sleeve 82 and efiects rotation of a rock shaft 95 upon which the rack 94 is. mounted, this shaft being provided with a fixed crank arm 96 connected with a crank arm 97 upon the sleeve by a link 98, the rack 94 also acting as a lifter for the tone arm when the playing of the record is complete.

From the description thus far it will berecognized that movement of the ejector finger 29 to deliver a record to the turntable will start the operation of the machine, and by engagement of the record with nausea:

the proper stop 74 or 75 will swing the control arm 69 and start the motor, at the same time releasing the

lever arms

79 and 80 to allow the tone arm to swing toward the face of the record and the centering pin to engage the opening in the center of the record disk and hold it during the playing operation.- It is to be noted that the runwa 28 is so arranged as to allow the center 0 the record to fall below the center of the turntable and to stop after having passed its center, the action of the centering pin thereafter shifting the record to its proper position and thus eliminating the necessity of exact register of the records with the axis of the turn-table.

Referring to Figs. 17 and 18, it will be seen that the record is there shown as provided with arcuate protrusions 99 which are arranged concentrically with the axis of the recor and upon the playin face thereof. These members are preferab y made of various materials and may be either formed as a part of the record or applied thereto by an adhesive substance.

In Fig. 18 it will be noted that the members are mounted upon guide strips 100 which are arcuate and which will permit them to be set in proper relation to the last of the tone grooves u on the. record, after which the strips may e torn away. These protrusions are adapted to be engaged by a contact member 101. which is carried by an arm 102 fixed to the reproducer arm 88. The end of this member 101 is adapted to normally lie close to the face of the record disk without touching the same and to be moved rearwardly when encountering the protrusions. This action will bring switch

fingers

103 and 104 into contact with each other and thus close a circuit through electro-magnets 105 and a source of electric supply 106 which are shown in Fig. 15 as bein wired in series.

T e magnet 105 is mounted above the floor 12 and is adapted to influence an armature 107 normally dependent therebeneath, as particularly shown in Fig. 5. hen this magnet is actuated it will swing an arm 108 toward the axis of the turn table at the rear of which it is disposed and into the path of travel of a face cam 109 protruding from the rear of the turn-table. The pivot of the integrally formed

members

107 and 108 is carried upon a bearing 110 which is fixed to a rock shaft 111 and which allows swing the arm 108 toward the rear face of the turn-table. In order to hold the memher 108 in the path of travel of the protrusion 109 after the magnet 105 has been deenergized, a triangular-shaped lock plate 114 is provided. This plate is pivoted to a shaft 115 extending transversel of the shaft 111 and therebeneath, the p ate being disposed with its center of gravity ofl' center from its axis, thus exerting a downwardly swinging force. The plate is normally held upwardly as it strikes the side of a finger 116 extending outwardly from the side of the armature 107. As this armature is raised upwardly the plate will fall down and beneath the finger, thus holding the armature against downward movement.

Fixed to the opposite end of the shaft 115 is a second look plate 117, particularl shown in Fig. 7. This plate is formed wit a shoulder 118 normally supporting the weight lever 112 and is further provided with a pin 119 adapted to be engaged by a fixed arm 120 carried upon the shaft 115. The lock plate 117 is free to rotate upon the shaft 115, and when the magnet lifts the weight lever 112 will fall with its shoulder 118 beneath the lever and support the same. This action will lock the lever 108 in its rearmost position.

The upper end of the arm 108 is fitted with a connecting link 120 which extends away from the turn-table and engages a crank arm 121 mounted upon a shifting shaft 122. This shaft is rotatably held in bearings upon the top of the floor 12 and carries a shifting yoke 123 at its outer end. The fork of this yoke is adapted to engage an annular groove in the hub of the sliding gear 57. As particularly shown in Fig. 1, this gear is splined upon the shaft 53 and will thus be shifted by the yoke into mesh with the driving pinion 58 carried upon the spindle 25 of the turn-table. The shaft 53 carries the disk return cam 52, the centering pin and tone arm restoring cam 124 and the magazine operated cam 125. The cam 124 is provided with a connecting rod 126 which extends downwardly and unites at its lower end with a crank arm 127. This arm is carried upon a shaft 128 extending horizontally and fitted with a second crank am 129 which extends across the machine and be neath the

levers

79 and 80. This lever is fitted at its extreme end with a link 130 which connects with the lever 79 and intermediate its outer end and its axis with a link 131 connecting it with the lever 80. A weight 132 is dependent from the outer end of the lever and exerts a force to swing the

levers

79 and 80 downwardly.

The cam 52, as previously Stated, .acts through the connecting link 55 to swing the record returning arm forwardly. This arm is adapted to engage pins extending outwardly from a shifting bar 133 which is dependent from the floor 12 and ma swing in either direction horizontally. Pins in the forward end of this bar are engaged b the shank 33' of the lifting member 33, w ich,

by encounterin the lug 33 upon the weight non-pla ing position when the bar 133 is.

swung orwardly, as will be the case during the movement of the record return arm to carry a record to the magazine.

Pivoted upon the pin 135, as clearly shown in Fig. 5, is a vertically swinging lever 136 which extends toward the timing shaft 53 and is ada ted to be encountered by a lug 137 carrie upon the gear 57. Below the pivotal point of this lug a switch arm 138 is formed as a continuation of the lever 136 and is pivotally connected by a link 139 to the switch member 140, as shown in Fig. 19, the opposite end of this member 140 being connected with the member 69 by the link 68, thus providing mechanism which, when this arm 136 encounters the lug 137, will swing to break the electrical contact in the switch 66 and cause the stop mechanism supported upon the arm 69 to be restored to its original position irrespective of whether the record played was a small or large one. The cam 125 is particularly shown in Fig. 6, where it will be seen to be engaged by a roller 141 which is carried on the upwardly extending end of an operating link 142. This link extends along the floor 12 and engages a ratchet lever 144 carrying a ratchet pawl 145 at its outer end. This pawl is adapted to engage perforations 146 in the side of the magazine shell 45 and to move the magazine the distance of one record. The pawl is spring-pressed and its action is supplemented by a lock pawl 147 which engage the same holes 146 in the shell 45, these two pawls operating together to advance and lock the mechanism in any desired position, the formation of the members being clearly shown in Figs. 23 and 24. -While there has already been shown a method of operating the machine by means of coin operative push-buttons, this. however, plays a certain selected record. If it is desired to play one record after the other without manual operation it becomes necessary to silence the push button 46 and to throw the pawl 145 and the pawl 147 into operation. It will be understood that if the push button is holding the rack, the awl could not move, and in order that both of these devices may not be accidentally placed in operation, there is provided the locking plate, as indicated at 149 in Figure 22. This plate is pivoted and is so disposed that when the top portion covers the push button Q, it will allow the ratchet pawl and lock to come into action and if it is moved in the 'o posite direction, to be interposed between t e pawls and the rack will permit the push button 42 to be operated while looking the pawl 145 and the lock pawl 147. To use the pawl 145 for continuous playing, it is necessary to disconnect the starting arm 29 from the member 35 b removing the pin 37.

A mec anismis provided for adapting the entire structure to automatically accommodate large or small records. As the machine normally stands, small records may be carried to the turn-table and removed therefrom without modification in the operating device. Large records, however, are provided to encounter a retarding finger 150 which is pivoted upon a pin 151 carried upon the upper runway 27. This finger is arcua-te and extends downwardly through an opening in the runway to be engaged by the large records and swung out of their path of travel. A crank am 152 is adapted to move with the fin r and to force downwardly upon a 153. This rod extends through the floor 12 and engages a counterweighted lever 154 beneath the floor. As shown in Fig. 2, this lever is pivoted to swing in a vertical plane and has an upper extension normally disposed beneath a ug 155 upon the extension 77 of the lower run way 28. When the lever 154 is moved downwardly it will be relieved from the support of the lug 155 and will cause the runway to fall a distance predetermined to correspond to half the increase in diameter of the record over the normal small size records. This action will automatically cause the finger 7 7' to encounter the rear end of the weight 93 on the reproducer arm and swing it rearwardly a corresponding distance.

In operation, a coin or slug is placed in the slot 48 of the control case, after which the push button 46 is depressed. The coin will have locked the member 47 with the pin 43 and will simultaneously force it inwardly toward the'shell 45 of the magazine. The shank 42'will -register with the perforation 44 in the magazine and thus lock the magazine against rotation, at the same time causing the yoke 40 to swing the vertical shaft 38' and thereby swing the obstructing member 38 out of the path of travel of the finger 35, it being assumed that the fingers .35 and 29 are locked together by the pin 37. The release of the

fingers

35 and 29 will cause them to swing upwardly, due to the weight exerted upon the member 31 and the finger 29 will therefore engage the under side. of the record with which it is in register and lift it over the ledge 21, thereafter permitting it to roll down the runway 28 as guided by the upper runway 27. When the returning arm is placing the, 12-inch record. back into the rack, a roller 51 on return arm 51 strikes a ainst the lower face of the track 28 and t us. returns the track to its normal position. While doing this the forked extension 77 of the lower track moves upwardly along the curved portion of the stop support 71 as indicated in Figure 4 and causes the stop 74 to swing horizontally and return to its original position close to the face of the turntable and in condition to accommodate the smaller sized records. As the disk reaches the opposite end of this runway, it will encounter the proper stop 74 or 75; it being assumed in the presentinstanoe that the disk is of the smaller size, it will therefore strike the stop' 74. The impact of the record with the stop will cause the stop and the arm 69, upon which it is mounted, to swin toward the back of the case, at the same time oscillating the switch member 140 connected with its lower end by the link 68. This will cause the blades 67 to become engaged and establish the motor circuit.

Simultaneous with this movement the lever 69 will swin from beneath the members 79. and and will thereby set the centering pin and reproducer arm support in motion in the manner previously described. The reproducer arm will be lowered a ainst the record as resisted by the air cushion in the cylinder 87, while the centering pin will be moved horizontally within its housing 84' to bring the record to a centered position upon the turn-table. While this is being accomplished the motor is overcoming the inertia of the driving mechanism and the turntable, and is driving it at its normal rate of speed. The needle will thereafter iminge against the face of the record and will carried therealong as guided by the sound grooves thereupon and the unbalanced weight 93.

As the tone arm nears the end of its playing stroke the switch member 101 will encounter the protrusions 99 upon the face of the disk and bring the

contact members

103 and 104 into register, thus completing the circuit through the magnet105 and source of electricalsupply 106. The magnet 105 will operate as previously described to throw the arm 108 into the path of travel of the cam lug'109, after which the gears 57 and 58 will be brou ht to mesh to operate the time shaft and t e mechanism carried thereby. The operation of the various cams will act as previously described to restore the centering pin and tone arm to their original positions and to feed the magazine after the record has been returned.

Experience has proven that it is desirable to entirely isolate the motor 65 from the phonograph mechanism in order to eliminate all mechanical vibrations and thus insure. a smooth and even tone to the phonograph. In the present instance, the motor 1s s own as restlng upon a V-shaped rib 65 WhlCll registers wlth a groove in the bottom of the motor case, said groove being ofi' center and allowing the motor to swing toward the various friction rollers of its transmission mechanism.

It will thus be seen that the mechanism here disclosed will operate to successively play phonograph records, removing them from and replacing them within a magazine that it may be actuated to repeat the same record, or by selectively disposing the records in proper register with the runways, may be caused to pla any record desired, the entire mechanis eing automatic in its actlon.
