PHON'OGRAPH ATTACHMENT.

Original application filed December 8, 1919, Serial No. 343,303. Divided and this application filed August '26, 1920. Serial No. 406,083.

This application is a division of application filed by me December 8, 1919, Serial No. 343,303, for phonograph attachments.- This invention relates to a phonograph attachment or mechanism for successively placing a number of phonograph or talking machine records on a talking machine platen or turn-table and performing automatically operations of parts of a talking machine. By the invention a number of select-ions or records may be played in succession without requiring any manipulation or effort on the part of the person using the machine.

The invention moreover provides a device wherein the sound box and stylus are automatically lifted from the record and the arm carrying the sound box shifted to one side of the turn-table to an out of the way position so that the face of the turn-table is free to receive a record, or another record, said lifting of the sound-box and shifting of the arm taking place afterthe completion of the playing of a record. The invention preferably provides means fol-automatically su plying or placing another record on the turn-table, after the sound-box has been lifted and the arm shifted and also preferably provides means for returning the arm to playing position and releasing or dropping the sound-box to bring the stylus again into contact with a groove in the record.

The invention further provides means for stopping the turn-table after the last record, or a desired number of records, has been played, and also means for locking and re leasing the turn-table stopping means by the takingofi' and putting on of sound records upon the turn-table. The invention also provides certain adjunctive means for carrying outwith greater perfection the operation of ,the foregoing parts, such as. means for braking or retarding the turn-table during a part of the time the stylus is removed from therecord, means for impositirely locking the reproducer arm in its out-swung position, and'means for assuring the replacing of the stylus at the pro er position on the record. he invention further provides :a means 6 of the character described which may be arranged or adjusted for different size records.

suitable construction, having a stylus orneedle 3, and carried by any suitable arm 4, convemently'a combined arm and sound conveyer. As here shown. the arm 4 swings on a vertical axis 6 in a suitable swivel-coupling or support 7 and the sound-box is conveniently connected to the arm through a gooseneck tube 8 swiveled around a horizontal axis and permitting of the lifting of the soundbox to and from the sound record, designated The arm 4 is normally adapted to move on its axis 6 to a position at one side of the turn-table when the stylus is out of engagement with a groove in the sound record. Numeral 11' designates a centering pin on the turn-table for centering the records placed thereon.

Record support or magazine.In starting to operate the machine, a sound record 1s placed over the pin 11 onto the turn-table 1.

Means are provided for holdinga number of records in position to drop successively one another, onto the turn-table after the first and succeeding records have been played. These means preferably comprise a pair of uprights 13, 14, having ledges or supports 16, 17, somewhat above the upper face of the turn-table for a stack of sound records X. The centering pin 11 is preferably long enough to extend through one or more of the sound records in the stack resting on the uprights 13, 14, and springs 19 are conveniently provided at the sides of the pin 11 for retarding the descent'of the record, when released from the stack, onto the turn-table. The uprights 13, 14, are conveniently mounted in slides 21, 22, in which they may be moved in and out from the axis of the turn-table to provide for records of different diameters, fastening screws 23 being provided for holding the said upright fast on the slides. The ledge 17 is formed upon an arm or lever 25 pivoted to the upright 14, and is adapted to be withdrawn from beneath the stack, as hereinafter explained, to release the lowermost record, said upright 14' also having thereon a pivoted-arm 27 which is adapted to be moved under the next to the lowermost record, at the same time, or somewhat previous to thetime the ledge 17 is moved from beneath the stack,'the remaining records in the stack being supported during the time theledge 17 is withdrawn, by the ledge 16 and the arm 27. -The ledge 16 is preferably made slightl yieldable as by means of the spring -29,' w ereby the ledges are kept in closer contact with the edges of the record. -A connection 31 is provided between the pivoted arms 25 and 27, the arrangement being such. that when the upper end of the arm 27 moves inward, the upper end of the arm 25 moves outward and vice versa.. f

.The arm 27 may be rocked in any suitable manner to release a record from the stack.

For this purpose, a longitudinally" slidable rod 33 may be provided, said rod being provided with a two-face cam 34, the end of the arm 27 projecting into the'groove between the two faces of said cam, as shown in Figures 1, 3 and 7. The rod 33 may be moved back and forth by hand, if desired, or as is preferred, automatically by means carried by the reproducerarm 4. These means may comprise a lever 43 having a weight 47 on one end thereof, explained more fully hereinafter, carried by the said arm 4 which weight strikes within a spring fork 36 on the end of the rod 33, and pushes the rod 33 so as to rock the lever 27 to release a record, the said rod 33 being pulled in the opposite direction by the arm 4 when it is moved inward toward the turn-table, the spring arm 36 grasping the weight 47 until the rod 33 reaches the end of its movement. The weight separates from the spring fork 36, whereupon the arm 4 moves free of the rod 33. This latter movement of the rod swings the lever 27, to bringthe parts in position to release another record.

80mm boa: lifting mec lzanism.Attached to the arm 4 is a bracket 40, Figures 6 and 12. Pivoted in the bracket 40 as indicated at 42 is a lever 43 one arm 44 of which extendsunder the sound box 2, and the other- 'normally held up by a supporting piece 49 moving to and fro beneath the lever- 42 on a vertical pivot 50. For moving the supporting piece 49 from beneath the lever 42, there is provided a trigger mechanism 51 pivotally connected to the piece 49 asindicated at 52 and turning around the vertical pivot 50 of the supporting piece 49. The trigger 51 has ahooked end 55 passing up under one side of the supporting piece 49, and at its opposite end a lateral projection 53 adapted to strike against the centering pin 11 when the stylus nears the end of the record. Continued rotation of the record causes thetrigger to turn on its pivot 50, finally withdrawing the supporting piece from beneath the lever 43, whereupon the weight 47 causes the end 45 to drop, thereby. elevating the end 42, and lifting-the sound box, together with the stylus carried thereby,

from the sound record, thereby allowing the 01120 reco-rd. huneral 7 O designates a lever,

pivoted at 72, having a cam or inclined plane 74 at one end, (Figures 4,6) and having an arm 76 extending inward under the turntable 1, (Figure 8). Fixed upon the undersideof the turn-table are cams 78, 79 and 80 (Figures 1, 3 and 8). )Vhen the reproducer arm 4 is over the record and the parts are in playing position, the lever 704s in the position shown inFigure 1, the arm 76 being out of reach of the cams 79 and 80. lVhen trigger 51 operates to release the lever 43 and thereby to lift the sound-box 2, and allow the reprodueer arm 4 to swing outward to the side of the turn-table (position Figure 3), a projection 85 (Figures 1 and 12) on the lever 43 strikes against a shoe 87 on a leg 88 of a three legged lever 90, pivoted on vertical and horizontal axes, as indicated at 92, (see Figs. 1 and 8) when the said lever 43 falls under the actions of the weight 47, thereby turning the lever 90 on its horizontal axis and lifting its arms 95 and 96, the arm 95'having a projection or roller 98 which when lifted is brought into the path of the cam 7 8 on the underside of the turntable. shown in greater detail in Fig. 17, in which it will be-seen that the lever 90 is mounted for oscillation about a horizontal pivot 292, and for oscillation about a vertical pivot 492, provided on the member 92 and extending into the member 392. \Vhen the cam 78 strikes against the grooved roller 98, the lever 90 is turned on its vertical pivot, bringing the arm 96 against the lever (or a shoe 100 on the lever 70, Figures 1 and 8 thereby moving the lever around its pivot 72 to the position shown in Figure 8). The lever 7 0 has the lower end portion ofthe cam or inclined plane 74 provided with an up standing finger 74' (see Figures 1, 3, 4 and 6). lVhen the lever 43 has been released by the trigger 51, as previously described, it falls behind the finger 74' and in 'the path of movement thereof, as shown in Figures 3 and 4. Now when the 'lever 90 is turned the finger 74' engages the side of the lever 43 thus swinging the'arm 4 carrying the stylus and sound box to its'outer position. A spring latch (Figure 2) 99 serves to impositively lock the lever 70 in the position The mounting of the lever 90 is shown in Figure 8, to which it has been moved by the arm 96. The projection remains on the shoe long enough for the cam to effect the turning of the lever on its vertical pivot and the movement of the end 74- of the lever 70 'outwardQ After the projection 85 moves off of theshoe 87 and after the cam has disengaged the project-ion on the leg the latter falls down out of the way of the cam 78. The lever 90 is returned to initial position (i. e. the position shown in Figure 1) by any suitable means, as for example by the lever 70 when its end 74 is swung inward, as hereinafter explained.

The turning movement of the lever 70 brings its end 76 first'into contact with the cam 79, and after a short intervening interval, into contact with the cam 80. The cam 79' moves the lever 70 around its pivot 72, causing the inclined plane 74 on its opposite end to contact with the lever 43 carried on the reproducer arm 4 (the arm 4 having swung to its outer position beyond the turntable by this time, and a record having meanwhile dropped from the magazine on to the turn-table) and swing the reproducer arm inward to a position where the stylus is over the beginning of the sound-groove of the record. A pin or project-ion 103 (Figures 1, 12, 13, 14, 15) on the lever 43 fitting in a slot or groove 105 in a guide 107 alongside the swivel coupling 7 of the reproducer. I

arm, prevents the lever 43 from being turned on its pivot 42 (see position A, Figure 15'). Consequently the weighted end of the lever remains lowered, and its opposite end remains elevated, the sound box being thereby prevented from lowering and the stylus kept out of contact with the record during the inward swinging movement of the reproducer arm 4. 'When the projection 103 reaches the end of the groove (corresponding to the position of the stylus over the beginning of the record groove)lft;he pin 103 has entered a groove in a ivoted forkedpiece 109, which forked piece, when turned to the position shown in Figure 14, prevents further movement of the projection 103 (and consequently of the reproducer arm 4) around the axis 6. but permits upward movement of the projection 103. (See position B, Figure 14.) The upward movement of the projection 103, with the consequent turning of the lever 43 on its pivot 42 and lowering of the sound-box and contacting of the stylus with the record, occurs when the cam -80 comes into contact with the end T76 of the lever 70, causing the lever 70 to resume its turning movement around the pivot 72, and the inclined plane 74 to lift the end of the lever 43 carrying the pm 103.

Playing of the sound record thereupon begins.

When the weighted end of the lever 43 is lifted by the inclined plane (4, the trigger piece 51 is allowed to turn under the influence of spring 60,'and thereby bring the sup porting piece 49 beneath the lever 43, the weighted end of the lever 43 being thereby prevented from turning the lever 43 on its pivotv 42 when the reproducer arm is swung or fed inward by the engagement of the stylus in the spiral groove of the record.

Moreover when the lever 43 is lifted by the inclined plane 74, the pin 103 is lifted out of the forks of the forked piece 109, into line with a tappet 111 ona pivoted latch 113, position C, Figure 14. The forked piece 109 has a tail-piece 115 which is caught and held by the latch 113 when the forked-piece is lifted to upright position. The forked piece is weighted as indicated "at 117 and bears against a resilient stop 119 as shown in F igure 15, so as to normally hold the mouth of the fork on a level with the groove 105. )Vhen the pin 103 on the lever 43 comes into contact with the tappet 111 (as the reproducer arm moves over the record during playing) the tailpiece 115 of the forked piece 109 is released. The resilient stop 119 yields in order to permit the pin 103 to pass the forked piece 109 in entering the groove 10:7. see the dotted line position, Figure 15.

Means for retarding zfurn-zabZe while reproaacer arm is being swam-g to side of turntabZe.-During the time the reproducer arm is moving to a position at the side of the turn-table, the stylus being lifted from the record, it is desirable to apply a retarding force on the turntable 1 to prevent the turn table from speeding owing to the lessened resistance to its rotation To this end, the lever 70 may be provided with a resilient arm 121 carrying a brake 123 (Figures 1, 3 and 8) adapted to bear on the periphery of the turntable '1. The resiliency of the spring-arm 121 determines the braking force of the brake, and is not so great as to stop the rotation of the turn-table. After the-reproducer arm is swung to the position at the side of the turn-table, it is desirable to re lease the turn-table from the brake 123, in

order that the full force of the motor may be effective in returning the reproducer arm to playing position (the motor acting through the cams 79 and 80, lever 70 and inclined plane 74). For this purpose there may be provided an arm 130, pivoted at 131.

and having an upstandingpart 133 adapted to contact with the reproducer arm 4 as it moves outward (conveniently through a resilient arm 135 on the lever 43) and bring a boss 137 on said arm 130 against a tailpiece 139 attached to the brake 123, and thereby remove the brake 123 from the turntable, as shown in Figure 3.

Mechanism for stopping turn-table.-

I 'When all of the records have been played,

it is desirable to stop the turn-table. The.

means for this purpose may comprise a to be engaged by a stepped pawl 160 having 1 a number of steps or notches 161 corresponding to the number of notches on the lever 150. The stepped pawl 160 ispivotally connected to the lever and a spring 163 may be provided for holding it down. When the .lever 90 is turned around its vertical pivot 92 (by the cam 78 as hereinbefore explained) the stepped pawl 160 is pressed forward into contact with the tail 158 of the pawl 156,

thereby turning the pawl 156 on its pivot, the amount of movement imparted to the pawl 156 being sufficient to cause it to move from one notch in the lever 150 to another. Upon the return movement of the lever 90, the stepped pawl 160 is carried back toits initial position the next forward notch 161 thereof dropping behind the tail 158 during the return movement. A beveled face 163 on the pawl 160 striking against a projection 165 lifts the pawl 160 at each oscillation so that when the pawl drops off of the projection 165, any one of the notches on steps 161 has been lifted high enough to fall upon the tail 158 of the pawl 156. At each oscillation of the lever 90 the pawl 156 moves'forward one step or notch on the lever 152, and, after the last record has been played, it moves off the end of the notched arm 152 of the lever 150, allowing the spring 154 to pull the brake shoe 151 against the turntable and stop it.

Mechanism for looking turn-table stopping means in stoppingp0siti0n. Means may be provided for automatically locking the stopping means in stopping position. These means may comprise a rock-shaft 17 0 extending under the turn-table and having an arm 171 pressed upwardly by a" spring 172, and an arm 174 with a rounded part 175. (Figure 5.) The arm 171 is normally held against the upward pressure of the spring 172 by means of a spring pressed latch 177. After the pawl 156 passes off of the notched arm 152 it strikes the latch 177 and moves out of engagement with the arm 171 which arm 171 is pressed upwardly by the spring 172 rocking the shaft 170 and allowingthe arm 174 beneath theturn-table to rise. The turn-table is preferably provided with a slot 180 (Figures 1 and 3) into and through which the arm 174 may rise when all the records have been removedfrom the turnfrom being turned to release the turn-table while no record is on the turn-table. The placing of a record onthe turn-table depresses the arm 174, rocking the shaft 170 and carrying the arm 171 below the arm 152, whereupon the lever 152 may be turned with its .pivot to release thev turn-table, the pawl 156 moving back to its initial position in the first notch in the arm 152, under the pressure of its spring and the latch moving forward over the arm 171, thereby resetting the stop actuating and stop looking mechanism. A stop 181 may be providedfor limit ing the HP-POSltlOIl of the arms 171 and 174.

Mechanism for adjusting. the device for cZ-ifl'erent diameter recortZa-Jn order that the stylus may be dropped into the beginning part of records of different diameter, as for example records of 10 and 12 inch diameter the guide 107 is carried by a slidable part or plate 190 (Figures 13, 14, 15, 16). A clamp-screw-l91 serves for holding the plate 190 in its different positions. An indicator 192 may serve for indicating the position of the guide 107 and plate 190 for various size records. \Vhen the guide 107 is set-for 12 inch records, for example, the pin 103 on the lever 43 will reach the end of the slot 105 in the guide 107 at a greater angular distance from the centering pin 11 than for 10 inch records. As the inclined plane 74 rocks the lever 43 at the point where the pin 103 leaves the slot 105 (as,

hereinbefore explained) lowering its end 44, the sound-box 2 will be lowered at a point which will be more radially distant from the centering pin 11 than for 10 inch records, as is required.

General description of operation.lVhen a record is placed on the turntable the arm 174 is depressed moving the arm-171 from behind the bell lever 150 and allowing this lever to be turned to release its brake-shoe 151 from the turn-table, when it is desired to start the talking machine. A plurality of records are placed on the ledges 16,17 above the turn-table.

lVhenthe turn-table is released from the By adjusting the plate 190 carrying the guide 107 the lever 43 may be made to lower the sound-box at difierent distances from the center-pin 11 in accordance with the diameter of the record. The uprights 13,

. 14 are also adjusted for the difi'erent size After the stylus 3 reaches the end part of ducer arm 4 to be swung to one side by its swinging mechanism;

When the weight 47 rocks the lever 43, a

projection 85 thereon strikes the shoe 87 on a' lever 90, raising theends 95 and 97 of said lever around the horizontal pivot and bringing a roller 98 thereon into engagement with a cam 7 8 on the turn-table which moves the lever 90 on its vertical axis, causing it to turn the lever to the position shown in Figures 3 and 8.

A brake shoe 123 carried by the lever 70 bears on the turn-table to retard its movement during the time the reproducer arm is moving outward.

In the final part of its outward movement, the reproducer arm 4 strikes a lever 130 moving it to release the brake 123 and the weight 47 pushes the rod 33 causing the cam 34 thereon to rock the levers 27 and 25 to release a sound-record from the underside of the stack above the turn-table, the released record falling onto the turn-table during the time the reproducer arm 4 is to one side of the turn-table (position Figure The cams 79 and then successively come in contact with the end 76 of the lever 70 turning it around its pivot and moving the reproducer arm inward toward the turntable.

When the pin 103 on the lever 43 reaches the end of the slot 105 in the guide 107 the inclined plane 74 on the lever 70 raises the end 45 of the'lever 43 and lowers the soundbox 2 to bring the stylus into contact with the sound record, whereupon the playing of the new record begins and a new cycle of operations begins.

When the reproducer arm 4 begins its nward movement the rod 33 is returned to its original position through the action of the spring-arms 36 engaging the weight 47.

In returning to such position the two-face cam 34 effects the resetting of the levers 25 and 27,.

The inward movement of the. end74 of the lever'70 returns the lever. to initial posltion. 1

Each time-the lever 90 is oscillated astepped pawl 160 carried thereby advances a pawl 156 one notch on the notched arm 150. When all of the records have been played and the pawl 156 moved beyond the end of the arm 152 of the lever 150, the lever 150 is released, and moved into contact with the turn-table, stopping it.

The removal of the records from the turntable allows the arm 174 to rise through a slot 180 in the turn-table, thereby turning the rock-shaft 170 and lifting an arm 171 behind the lever 150 and preventing it from being turned to release the turn-table until a record is again placed on the turn-table.
