When, however, the roller 33 has reached vthe position shown in Fig. 5, the cam plate 25 then takes up the work and the right hand side of its periphery, as viewed in Fig. 5, acts upon the roller'ss to thereafter return the actuating lever 31 in a clockwise direction to its ’normal position. The actuating lever 31 is then held in its rest position by means of a coil spring 35 which surrounds a toggle member 31 slotted at its ends.

As soon, however, as the lever 3| begins its initial counter-clock~ wise rotation under the in?uence of means here inafter described, the pin 61 engages the cam edge 49a and rotates the cable lever 49 in a coun ter-clockwise direction rather rapidly. This ?rst causes the lever 49 to take up the tension in the spring 53 and the slack in the cable 55, and then to exert a pull on the pickup arm 6| to quickly raise the pickup 63 above the played record. By this i time, the actuating lever 3| has reached a posi tion such that the are 59 is concentric with the pivot post 29. Hence, no further counter-clock wise movement of the cable lever 49 takes place as long as the pin 6'! passes over the arced portion (ii) 59 of the cam edge 49a, the pick-up-arm 9| being held in raised position all this time. The pickup arm 6| is pivotally mounted on a supporting post 59 rotatably mounted in a bush ing 'II on the plate I I and extending through the “ bushing 'II below the plate II, the bushing 'II that, when the detent lever 95 is in the position shown in Fig. 3, the left-hand edge of the notch I93 (as viewed) is spaced from the parallel edge of a toe 81c on the lever 81 a ~distance su?icient to accommodate a downwardly extending pin III’! on the plate ‘I9. Normally, that is, during playing of a record, the arm 3Ic of the actuating lever 3| is in engagement with a pin I99 on the detent lever 95 to hold the detent lever in the position shown in Fig. 1. After the needle 95 has entered the record terminal groove and the ac tuating lever 3| begins its counter-clockwise movement, the arm 3Ic gradually recedes from the pin I99 and the spring 9'! pulls the detent lever into the position shown in Fig. 3, at which time the pin IilI stops further clockwise move; ment of the ‘detent lever 95 with respect to the lever 81. Upon continued movementof the ac tuating lever 3| in a counter-clockwise direc tion, the arm v3Id continues ‘to rotate the plate ‘I9 counter-clockwise causing the pin I91 to en gage the cam edge I95 to cam the lever 95 back a little until the pin I97 passes the cam edge I95, whereupon the spring 91 pulls the detent lever 95 back to its extreme clockwise position, thereby trapping the pin I91 in the notch I93 between the left-hand side thereof and the edge and the post 69 being inclined from the Vertical about three degrees toward the turntable i3.

The pickup arm @I then be comes free to move over the. record to reproduce the same, and the above described cycle is re . onto the turntable, the pickup 63 will be properly . located thereon. vJust immediately prior to the release of the next succeeding record, the pin E35 strikes the lower end of the extension IZ'I ' on the lever i235 as the lever 8'.’ moves in a coun ter-clockwise direction.

Thereafter, upon ‘clockwise ,' movement of the lever 3?,the lever‘B-‘I moves in; this direction until the pin' I35 engages the step ' H9, whereupon further clockwise movement of the lever 8‘? is prevented. 'Since, at this time, the pin It] is locked between the left-handedge 60 of the U-notch I93 and the toe >810, it is obvious that the, pickup arm 6| will not move further in toward the spindle 9, and when it is subsequently lowered onto the record, it willland at the start receive hubs It? to which are secured. record separators I49 displaced from the shelves M5 both circumferentially and axially with respect to the . posts I3? and each being formed with a knife edge M5911. terminating approximatelyiadjacem the left-hand edge of the shelf I45, as-viewed in Fig.v 13..

The supporting shelf M5 is position shown in Fig. 11 as the record drops past it. The mechanism is sotimed that the record 70 formed'with an opening I46 through which’ ex- " tends an adjustable, ball-tipped '_ ' screw 459 ' is not released from the stack until after the ‘lever extension 81b has reached-the position threaded into the lever I 5!,‘the extent of‘pr‘oj'ec‘e tion of the ball tip-ofthe screw I59:throughthe ‘ , shown in Fig. 11, where it is clear of the lever‘ opening I136 being determined by a set ‘screw I61 I25 and its extension I2l'I.

When the separators I 49 are caused to rotate relative to the shelves I45, it is obvious that their hubs I41 will ride up on the pins I53 by virtue of the circular openings I51 therein, and thus the separators I49 will be raised slightly with re spect to the supporting shelves I45. Also, by the supporting shelves I45 that 10” records do not rest thereon. However, 12" records, which are usually thicker than 10" records, are of large enough diameter to engage the ball heads of the depressing the screws I59, the levers I5I will be moved in a clockwise direction, as viewed in Fig. screws I59 and depress them. This causes the lovers 15I to move in a clockwise direction, as The screws I59 are so located with respect to 14, thereby also effecting an elevation of the 10 viewed in Fig. 14, to thereby raise the separators I49 and thereby automatically compensate for separators I49 with respect to the shelves I45. the greater thickness of the 12” record next to The oppositely extending arms 3Ie and 3If of v be released. It will be noted, however, that the the main actuating lever 3'I carry pins I63 ad tops of the openings I51 in the hubs I41 still rest jacent to their ends which are received in elon~ gated slots I65 of a pair of slide bars I61.

During initial counter-clockwise movement of previously set forth. the main actuating lever 3I, and while the pick- up is being raised from the record in the manner from the turntable. To make this possible, it is previously described, the pins I63 move in the slots I65 to take up the play afforded thereby and without any effect upon the slide bars I61. By the time the pickup has been raised from the played record and at approximately the time when the lever arm 3Id engages‘ the pin 83, the pins I53 have reached the opposite ends of the slots I35 and the record supporting posts begin to rotate. As the posts rotate, the record sup porting shelves I45 begin to slide under the lowermost record of the stack and the record sep arators I49 move toward the record stack, the knife edges I49a thereof seeking to enter be tween the lowermost record and the next upper one. The separators I49 are so adjusted with respect to the shelves I45 that the knife edges 149a thereof will engage the edge of the lower most record. When this happens, further rota tion of the separators I49 is temporarily pre vented,'but since the pins I53 continue to rotate with the hubs I43 and the posts I31, the pins I53 will cam the separators I49 upwardly until the knife edges I49a are in a position to enter between the lowermost record of the stack and the next upper record, whereupon the separators 349 will slide in between the two lowermost rec ords. Shortly thereafter, the trailing edges of the supporting shelves I45 (for example, the left ‘ After the entire repertoire has been played, it is necessary to remove the accumulated records necessary to remove the supporting shelves I45 from their normal, record stack supporting posi tion. To do this, it is merely necessary to raise the posts I31 until their pins I19 clear the slots I11 in the bushings I13 and turn the posts through an angle such that the shelves I45 will clear the 12" records, thereby permitting re moval of the accumulated records. Before next operating the machine, it is, of course, necessary 40 to reset the posts to the position shown in Fig. 12 with'their pins I19 back in the slots I11.‘ ' The weight of each of the hubs I41 and the separators I49 is normally su?icient to insure engagement of the upper portion of the opening I51 with the pin I53 so that the action previously described will be insured. However, to further insure that this action will take place properly, a coil spring 18I may be placed around the upper end of the hub I41 and a C-washer or the like I83 secured to the upper end of the post I31. The spring I8I will then exert a force upon the hub I41 and thus press the latter against the pin I53. A cover I80, frictionally ?tted onto the upper end of the hub I41, conceals the spring I8I and associated parts from view. ' To effect the automatic cycle of operations heretofore described, there is provided a fric tion ?nger I95 ?xed to a hub carried on the post 8|. A spring member I81 which comprises a hand edge of the shelf I45 in Fig. 13) will clear the lowermost record, thereby freeing it to be pair of substantially parallel armsembraoing the hub of the friction ?nger I35 to frictionally grip dropped down along the spindle 9 which extends through the entire stack, and onto the previously force applied by the clutch spring I81 to the hub‘ of the friction ?nger being adjustable by means played record on the turntable. If, as previously described, the released record is a 10" record,. it will not strike the locating post III and the pickup will- subsequently automatically come to rest at the starting position thereof. Eventually, when the main actuating lever 3| begins its clock wise rotation, its pins I53 will push the slide bars I61 back to the position shown in Fig. 1 and thereby return the posts I31 to their normal posi tion, the separators I49 sliding away from under the then lowermost record so that the entire the same is secured to the plate 19, ‘the frictional of a screw I39 (Fig. 12), so that the friction ?nger I95 and the plate 19 may assume various angular positions with respect to each other. As the pickup arm 6! moves over the record and the plate 19 is moved in a counter-clockwise direc tion, it carries with it the friction ?nger I85, also in a counter-clockwise direction, until the free end of the ?nger I85 engages a pin I9I which extends through a cycle initiating pawl I93 piv oted to the underside of the plate II and re strained against free movement by a suitable ' 2,412,441 , ll 7.12 arm 31d of they actuating lever.

Cooperating with the pawl I93 is a tripping member ZOI pivoted on the upper face of the gear‘ in a-counter-clockwise direction to bring the edge 2|‘! thereof against a pin 2 I9. on the friction fin ger I 85. The friction ?nger I85 thus. becomes locked against movement in either direction. When the plate ‘I9is later returned in a counter clockwise‘ direction, its pin 2! 5, acting in the slot 293, rotates the regulating plate 2!! ma clock I-‘I eccentrically thereto and constantly urged in a clockwise direction by a spring 293.

"Thereupon, the friction ?nger 135 moves withv the plate ‘I9, having been preset to the required relation ‘therewith. Continued movement‘ of the pickup arm over the record subsequently brings the friction ?nger into en-r gagement with the pin I9I of the pawl I93 and the previously described action takes place.
