Application filed February To all whom it may concern:

Be it known that we, PAUL KOSEGKI and HENRY A. GARLsoN, both citizens of the United States, and residents of Kenosha, in the county of Kenosha and State of Wisconsin, have invented certain new and useful. Improvements in Multiple Record Players for Phonographs; and we do hereby'declare that the following is a full, clear, and exact description thereof.

This invention relates to a multiple record phonograph construction.

Objects of this invention are to provide a phonograph construction which will automatically play, in succession, a plurality of records, which will remove the records played and position the needle correctly fer the next record, and which will stop the machine. after all the records have been played.

Further. objectsare to provide a mechanism which will remove the records in a simple and quiet manner, which will not injure the iecords, and which utilizes .the ro-' tating diskfor effecting the removal without stopping the disk,-thus permitting the immediate playing of the succeeding record.

Further objects are to provide an automatic phonograph mechanism which is adapted to receive a plurality of stacked disk records upon the rotating disk, .which will successively play the records and remove the .55 of Figure 4:;

played records from the top of the stack, and in which the disk is so constructed that it automatically adjusts itself for the decreasing height of'the stack.

Further objects are to provide a multiple record phonograph construction -which is relatively simple, which is substantially fool proof in its automatic operation, and'which is not likely to get'out of order. I

Amembodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a plan View of the apparatus. Figure 2 is a sectional view on the line 22 of Figure 1.

Figure '3 is'\an enlarged section on the line 3-3 of-Figure 2.

Figure 4 is a sectional view on the line 4.4 of Figure 5. Figure 5 is a sectional view Figure 6 is a sectional view on the line I 66 of Figure 4.

driving gear 5 in the usual manner. ,The

hub 3 is loosely splined, as indicated at 6, to the driving spindle 4, and such driving spindle carries a collar 7 spaced from the hub 3. A helical spring 8 loosely surrounds the hub and bears against a flanged portion 9 thereof, and against the colla'r.7 of the spindle, thus yieldingly supporting the disk.

2. The disk is adapted to carry a plurality of records'lO, the spring 8 yielding as records are added to thestack and maintaining theface of the uppermost record at approximately the same horizontal level irrespective of the number of records remaining in the stack. Preferably the usual governor is provided and comprises rotating weights or balls 11 connected to a movable friction disk 12 carried by the governor shaft. This fric-' tion disk is adapted to be drawn by the on the line governor into contact with the control arm 13, such control arm being regulated by thethreaded thumb screw 14 in the usual manner. A brake or stop 15 is carried by the outer end of a lever 16 and is adapted to engage the periphery of the friction disk 12 when it. is desired to stop the rotation i of the mechanism. This lever 16 is pivotally carried by a bracket 17, as shown most clearly. in Figure 5, and is provided with an outer end 18 mounted below 'a plunger 19, such plunger having its upper end positioned adjacent the periphery of the disk 2, as shown clearly in'Figure 1.

Upon referring toFigures 1 and2, it willbe seenthat the top 1 of the phonograph is provided with a downwardlyslanting portion 1- spaced from the rotating disk 2. This slanting portion carries a yieldingly supported disk 20 which is adapted to receive the discharged records. This disk is preferably provided with a hub 21 slidably carried by a pin 22 secured to a bracket 23 secured to the slanting portion 1' of the top,

as shown in Figure 2. A helical spring 24 is positioned between the bracket 23 and the flanges of the hub 21 and thus yieldingly a suitable supports the stationary disk 20. This disk is preferably provided with an ear 25 apertured to slidably receivea pin 26 fixed to.

the slanting portion 1 of the cover to prevent rotation of the disk.

Further, it will be noted from Figure 1 that the disk is cut out, as indicated at 27, to accommodate the operators fingers when removing a stack of records from the stationary plate20. A pair of angle iron clips 28 are secured to the slanting portion 1, as shown in Figure 1, to maintain the edges of the discharged records in alignment.

A pair of guides 29 and 30 are provided and are positioned on opposite sides of the disks 2 and 20, as shown most clearly in Figures 1 and 2. The track 29 is preferably provided with an inwardly directed flange 31 to receive the record while it is being discharged and the track 30 is provided with a plurality of rollers 32 upon which the oppo- *site edge of the record may freely travel.

It is to be noted that the rollers 32 eX- tend in a substantially horizontal line for a portion of their extent and, thereafter, extend downwardly along a slanting line, as most clearly shown in Figure 2, to correspond to the horizontal surface 0f the top 1 and of theslanting surface of the portion 1,

Preferabl a plurality of rollers 33 are carried by t e guide 29 beyond the flange 31,

and these rollers also slant downwardly corresponding to the slant of the portion 1.

It is to be noted that the track 29 is provided with a wedge-shaped end 34 adjacent the disk 2 and,-from reference to Figure 3, it will be seen that this tapered end is provided with a curvedvertical surface approximating the curvature'of the records 10 carried by the disk 2. This solid face 'prevents catching of the records beneath the flange 31 and permits the upward lifting of this side of the records above the flange during the discharging operation.

The mechanism for discharging the records comprises a roller 35 (see Figures 1, 3, 5 and 6). This roller is provided with a groove 36 adapted to fit the outer edge of the record, as shown in dotted lines in Figure 3, and this groove, it will be noted, forms a relatively thin lip 37 on the under side of the roller which fits below the edge of the record during removal. This roller is revolubly carried by the outer end of a short link 38 pivoted to an arm 39 (see Figures 1, 3 and 6) of a slidably mounted pin 40 (see Figure 6). The pin 40'extends through guiding sleeve downwardly through the top 1 of the phonograph. This link is urged in a counter clockwise direction, as viewed in Figure 3," by means of a leaf spring 41 and is held in contactwith the upper end of a cam-like guide 42 rigidly secured to the top 1 of the phonograph.'

When the phonograph is in operation and a record has been played the tone arm is moved laterally. by means hereinafter described, and the pin 40 is raised. This causes a lifting of the roller 35 and as the link 38 travels upwardly, it will pivot with reference to the arm 39 as it is held in sliding contact with the cam-like bracket or guide 42. This permits a gradual tiltingof the roller 35 and causes the groove 36 thereof to receive the outer peripheral edge of the uppermost record. Continued upward and rocking motion of the roller 35 lifts the record, as shown in dotted lines in Figure 3, and places that side of the uppermost record adjacent the roller upon the flange 31 of the guide 29 illustrated in Figure 1, it being noted that the member 34 is also provided with aface aligningwith the upper side of the flange 31. Rotation of the disk 2 in the direction shown in Figure 1-, causes the record to roll along the guide 29 to the left, as shown in Figure 1, as the side of the record opposite the flange 31 rests temporarily upon thevrotating disk and is thus carried to the left with reference to the parts, as illustrated in Figure .1. This motion of the record is relatively rapid and causes the record to slide along the guide rollers 32 and 33 until it slides upon the stack of records carried by the disk 20 and is completely discharged from the rotating 'disk 2.

Referring to Figures 4 to 8, it' will be seen that a gear 43 rs carried by a bracket 44 secured to the top 1 of the machine and is provided with teeth upon its face. These teeth are put in driving relation with the teeth of the gear 5 by means of the idler 45, as shown in Figure 5, and thus the gear 43 is driven in a continuous manner from the gear 5. It is to be notedthat the gear 43 is in reality a drum member and is provided with a plurality of regularly spaced radial apertures 46. A disk 47 is mounted coaxially with the gear 43 and is free to rotate independently of this gear. It is provided with a cam arm 48 for a purpose to appear later and is provided with a curved shoe 49 fitting loosely over the face of the gear 43. This shoe carries a pawl 50 whiclris pivoted thereto and provided with a tongue 51. It is to be noted that the shoe 49 is provided with an aperture through which the tongue 51 may project, as clearly shown in Figures 6 to 8. A spring 52 is carried by the shoe and .bears against the pawl urging it in a counter clockwise direction, as viewed in Figure 6. The pawl 5 is provided with an outwardly projecting control arm 52 which is normally held incontact with a horizontal slide 53, as shown in Figure 6. The slide 53 is most clearly shown in Figure 4 from which it will be seen that the slide is substantially rectangular and is carried by a bracket 54 secured to the top 1 of the machine.

It is to benoted from reference to Figure 4 that the rear end of the slide 53 is provided with a diagonal slot 55 for a purpose to appear immediately.

The bracket 54 also pivotally carries a lever 56 which projects upwardly through the top 1. This lever is integrally formed with a right angle extension or arm 57 and with an upwardly extending tongue 58. The tongue 58 fits within the slot 55 and thus when the lever 56 is rocked to the left, as shown in Figure 7, it will'retract the slide 53 and-free the arm 52 of the pawl 50, thus permitting the spring 52 to urge the tongue 51 into one of the radial apertures 46 in the gear 43 thus locking the shoe 49 temporarily to such gear. ly held in the position shown in Figure 6 by means of a leaf spring 59 provided with a depression engaging a pin carried by such lever, as shown in Figure 6. A tension spring 60 urges the lever 56 in a counterclockwise direction, as shown in Figure 6, and the lever is restrained from movement, under normal conditions, by engagement with the spring 59.

The means for moving the lever 56 comprises a small lever 6l pivotally carried by a bracket 62 secured to the upper side of the 6. This lever is provided with a segmental upper side which is provided with ratchet teeth 63 adapted to be engaged by a small pawl 64 yieldingly carried by a spring 65 secured to the tone arm 66.

Referring to Figures 1 and 5, it will be seen that the tone arm 66 is pivotally carried by the top in the usual manner and is provided with a transverse sleeve 67 within which the goose neck or movable portion 68 of the tone arm is carried; the outer end of such goose neck carrying the reproducer 69. This curved movable portion of the tone arm is provided. with a rearwardly extending lever 70 rigid therewith. This lever 70, as may be seen from Figure 5, is provided with a rigid extension 71 which projects downwardly through a suitable aperture in the top 1. It is provided at its lower end with a right angle extension 72 shown in dotted lines in Figures 4 to 8. It is to be noted further that the disk 47 (see Figure 4) is provided with an outwardly projecting pin 7 3 and that such pin, when carried by the disk 47, around its path of travel, will contact with the arm 57 of the lever 56 and will also engage the angular extension 72 of the member 71. I

The operation of the apparatus is as follows :-The records are stacked upon the disk 2 to the desired extent and the phonograph is started. When the needle 74 of the reproducer 69 (see Figures 1 and; 5) arrives -p groove, it will be at the end of the record received by the eccentric groove .75 and the The lever 56 is normal-.

1 of the machine, as shown in Figure tone arm will beflrocked back and forth. This causes the pawl 64 (see Figure 6) to engage the teeth 63 and, due to the rocking. motion of the tone arm, transmits motion to the lever 61 and forces the lever '56 in a counter clockwise direction, it being noted that when the end of the record is reached that the pawl 64 is positioned above the ratchet or segmental member 63. The tripping of the lever 56 retracts the slide 53, due to the slanting slot 55 and the tongue 58 (see Figures 4 to 8 inclusive) and permits the pawl 50 to couple the disk 47 rigidly to the gear 43. This disk is then rotated with the gear thus carryingthe elongated pin 73 2- around with it; This pin engages above the right angle extension 72 of the arm 71 and draws such arm downwardly thus rocking the lever downwardly and elevating the reproduce'r 69. Continued motion of the plate carries the arm 71 to the right in Figures 6 to 8 and thus carries the tone arm back to its initial position, as shown by the successive views Figures 7 and 8. During this movement the cam arm 48 of the disk 47 engages'the pin 40, as clearly shown in Figure 8, and thus elevates the pin and consequently the roll-er 35. The roller engages the edge of the uppermost record 10 carried by the rotatingdisk 2 and, as previously described, lifts one edge of such record-upwardly and causes 1ts discharge on to the stationary or non-rotating disli '20.

nrther motion of the disk or plated? permits the rod 71 of the lever 70 to rise and i thus gently lowers the needle 74 into contact with the next record. Rotation otthe records causes the immediate engagement of the needle in the appropriate'groove and playing of the next record then starts.

It is to be-noted that during the rotation of the plate or disk 47 that the pin .73 see Figures 4 and 7 depresses the arm 57 of the lever 56 and thus moves the lever into its initial position, as shown in Figure 6, ready for a subsequent tripping operation. This rocking of the'lever 56 in a clockwise direction back to its initial position projects the slide 53- and when the arm 52' of the pawl 50 approach'esits initial position it will en gage such slide and cause the pawl to rock and retract the locking finger 51 from the radial aperture 46 in which it had been set,

thus disconnectin the shoe 49 and arresting further motion 0 the disk or plate47.

. This action of the apparatus continues until the last record is removed from the disk 2. When this occurs, it will be noted that the needle 74 passes downwardly outside of the periphgral edge of the disk 2, as such needle had by the marginal portion of the records. This ermits the thumb screw 75 to rest upon the plunger 19 and the weight of the tone arm depresses such plunger and consequently rocks the lever 16 thus moving the brake 15 into engagement with the disk 12 of the governor and stopping the phonograph.

It will be seen that an automatic phonograph mechanism has been provided which willsuccessively play a plurality of records, which will remove the -records successively after they have been played, and which will,

in each instance, position the reproducer at its initial place ready for the playing of the next record.

n1smis so constructed that an ordinary 1ng a tone arm and a standard phonograph may be readily changed into an automatic multiple record phonograph in a simple and easy manner.

Although the invention has been described in considerable detail, it is to be understood a that the invention may be variously em bodied and is, therefore, to be limited only as claimed.
