This invention relates to phonographs and particularly to means for changing the records so as to play a plurality of records in series. y en object of the invention is to provide a machine of 5 this character in which both sides of the records may be played.

A further object is to provide means for changing the record which will lessen the danger of breaking records during the changing and inverting of the records to play both sides.

Further objects and advantages will become apparent as the description proceeds."

In the drawings reference characters 10 and i1 indicate the supporting structure of the machine slit in which the record playing table and its operating mechanism'are supported and 12 and 13 indicate frame mechanism in which the stack of records is supported. The record playing table .may be driven in any suitable way as by a conventional motor 15 supported on a bracket 16 depending from a part of the frame 11. Atone arm 17 of any suitable sort is mounted and operated to be moved into and out of playing position by .any well-known mechanism. This mechanism, since it forms no part of the invention, will not be described in detail as any well known tone arm and operating mechanism therefor may be used with our machine.

- The mechanism for changing the records consists of a double fulcrumed transfer frame 19 which is pivotally attached to toggle links 20 and 40, the latter being pivoted at 21 to a part of the frame in which the stack of records is supported.

The transfer frame 19 has transverse shafts22.

19. When this frame is tilted to move the records beneath the stack of records on therecord support or to move the records into playing Position on the record table, the record frame 19 is tilted in the following manner: A motor 28 drives a pulley 29 by meansof a belt 30. The pulley 29 is mounted on a shaft on which is a worm 31 which meshes with a worm wheel 32 A pinion 33 on the same shaft which supports the worm wheel 32 meshes with a larger gear 34 mounted on shaft 35. Upon the outer end of this shaft are crankarms 36 having crank. pins 37 at their outer ends to which are connected links 38. The links 38 at their other ends are pivoted at 39 to the links 20 and 40. As will be seen from the mechanism-just described operation of the motor 28 will rotate the chains of gears just described to rotate the arm 36 and through the toggle mechanism just described will raise and lower the end of the frame '19.

A record base plate 86 is siidahly mounted on the top of the frame 19 and forms a supporting plate for the record after it has slid down the frame. A spring 87 is attached at one end to a lug on the underside of the plate 86 and at its other end to the shaft 39. The purpose of the spring 87 is to hold the plate 86 snugly on the top of the frame 19.

The record supporting frame 12 has brackets 41 positioned so as to extend within the frame and support astack 42 of records thereon. The brackets 41, as shown in Figure 3, are spring pressed inwardly and may be moved outwardly to permit a record to be moved upwardly and positioned beneath the stack of records. Pivoted to the frame 12 near the top of the record support is a record ejecting mechanism 43 which consists of a lever slotted at 44 and having a pin 45 extending through the slot. A tension spring 46 is secured to a lug 47 on the lever atone end and is secured to the pin 45 at the other, the spring normally tending to hold the lever 44 in a position to keep the upper end of the slot in engagement with the pin 45. The lower end of the slotted member is provided with a shoe 48 on one side of which is a small lug 49 for engaging the edge of a record to push the topmost record off the stack of records on the record support.

A bar 50 is secured to the front side of the posts 12 and has its ends turned up to provide brackets 51 in which is journaled a rod 52. The outer end of this rod has a lever 53 secured to it and a weight 54 is secured on the upper end of the lever and to the lower end is connected a tension spring 55, the spring being connected at its lower end to an arm 56 on a pin 5'7. The pin 57 is secured to the side of the frame 19. A rod 58, bent in the form of an inverted U, is rigidly secured at its upper portion to the rod 52. The lower ends of the legs of the U are bent up to provide hooks 59 for catching and holding a record in the position shown in Fig. 1. One of the brackets 51 is provided with

stop pins

60 and 61 to limit movement of the lever 53. To the rear side of the bar 50 is attached a plate 62, the purpose of the plate being to hold the stack of records within the frame as they are moved upward by the transferring frame. Plate 62 is cut away at 63 to provide slots for receiving the ends 64 of a plate 65 which plate is secured upon the shaft 22 upon which the frame 19 pivots-whenit is riding in the saddle 24. A tongue on the plate 62 is slightly bent forward so as to avoid having the edge of the record strike the edge of the plate and prevent their moving upward. The plate 62 is preferably secured upon the bar 50 by means of bolts 6'7 passing through slots 68 in the plate 62, the slots 68 providing for a slight.

vertical adjustment of the plate 62 so that the machine may operate with a different number of records in the stack or to take care of slightly different thicknesses in the records which are to be played. The plate 65 just described has the ends 64 bent up to provide hooks 69.

Means for stopping the records in playing posiv tion are shown in detail in Figure 9, this consists of a rod 71 which has its ends 72 bent out and journaled inthe frame 19 at 73. Stop brackets '74 are secured on the bar and provide means for engaging the edge of the record as it slides down the incline when the table 19 is in the position in which it is shown in Figure 2. A weighted arm 75 is secured on one end of the bent out portions '12. When the record frame 19 is moved to its horizontal position the weight 75 strikes against a stop 76 and swings the record stop brackets below the level of the frame 19. When, however, the record changing frame is tilted either into the position shown in full lines in Figure 1 or that shown in Fig. 2, the stop brackets '74 are rotated to the elevated position so as to engage .the edge of a record and limit its outward movement on the frame 19. A stop 80 limits upward movement of the rod '71. A bracket '77 is pivoted at 78 to the .frame of the machine and is'bent into U-shape to provide an upper ledge v'19 upon which the tone arm 17 rests. When the bracket '77 is raised therefore it lifts the tone arm to lift the record playing needle ofl the record. The bracket 77 is lifted by means of a pin 81 which extends through a side of the frame 19 and engages beneath a plate 82 on the bracket .77. When the frame 19 begins to tilt into the position shown in Figure 1 the pin 81firstbeneaththeplate82toliftthe engaging against the edge of the record forces the lever 43 into the position shown in Figure 2. As

69 passing up in the slots 63. As the arms64 tone arm oif the record. fie tone arm swings by gravity then to the position shown in Figure 3. A pin 84 in the tone arm strikes a lateral pin 85 on the bracket '78 so that the tone arm is limited in its outward movement and stopped in position to begin playing a record. In order to balance the weight of records and enable the machine to operate more smoothly a weight 83 is secured in the end of the frame 19.

Operation The operation of the machine is as follows: When a record has played, mechanism, not shown. starts operation of the record changing motor 26. This swings the frame 19 to the position shown in full lines in Figure 1 by means of the

gearing

31, 32, 33 and 34 and

link toggle mechanism

20, 38, and 46. When the frame 19 is tilted toward the left the record slides down over the rollers 26 to the end of the frame, being limited in its downward movement by the frame 12. The record changing motor continuing to rotate begins to straighten out the toggle and lifts the frame 19 to position the record beneath the stack of records 42 and to lift the stack of records to the position shown in Figure 2, the edges of the records sliding upward along the inner side of the plate 62. As soon as the topmost record reaches the shoe 48 it begins to compress the spring 46 and the lug 49 soon as the topmost record passes above the top of the plate 62 the spring 46 urging the lever 43 forward slides the topmost record over the top of the plate 62 until the record is caught in the hooks 59. It should be noted that as the frame 19 moves up the weight 54 is allowed to swing the hooks 59 in the position shown in Figure 2 so that the hooks are raised to the position in which they may catch the-.record as it is slid off the top of the record stack. 'I'he'record changing motor continuing to operate restores the frame 19 to the horizontal position and the hook 59 assumes the position shown in Figure 1 having the record heldin the hooks. As the frame 19 was raised to its elevated position the plate 65 on the frame 19 was moved' up so that the arms 64 engaged beneath a record in the record hooks 59 and lifted this record out of the hooks to position it on the frame 19, the hooks move up, the hooks 69 engage beneath the edge of the record to liftthe record out of the hooks,

and by the time the frame has assumed the position shown-in Figure 2 the record in'the hooks will have beenlifted out, inverted and rices on the frame in position to slide down to record playing position. As the record slides down to the position in which it is shown in Figure 2 its edge strikes the record stop brackets '74 so as to stop the record in exact position to be lowered upon the record table in exact playing position.

When the transfer frame 19 is in the inclined position shown in Figure 2, the portion 79 of the bracket 7'7 will support the tonearm in raised position so that the record may readily slide under the playing needle. -When the frame 19 is restored to its horizontal position therefore the record will be placed in playing position and the needle on the bent arm will likewise be just above its playing position. As the frame 19 reaches its final level the bracket 7'! will be lowered to position the needle on the record in position to play, and the playing will at once begin since the record I table is allowed to rotate continuously during the record changing operation. When the frame 19 1,920,986 has resumed its playingposition, mechanism, not

shown, stops rotation of the record changing motor. Such. mechanism being well known in machines for playing a multiplicity of recordsin succession it is deemed not necessary to describev it here as it forms no part of the invention in this case.

It should be noted that when the changing frame 19 is in record playing position, that is, when it is inthe horizontal position the stops '74 are below the top of the record playing table. If therefore the, operator wishes to play a' larger record than those in the stack 42 he may place a record on the table and play it without interference from any mechanism on the frame 19. This record, of course, must be manually placed on the table and played and removed without the use of the record changing mechanism.

It will be obvious to those skilled in the art that various changes may be made in our device without departing from the spirit of the invention and therefore we do not limit ourselves to what is shown in the drawings and described in the speciflcation, but onlyas indicated in the appended claims.
