1': Claims. (01. 214-10) This invention relates to improvements in automatic phonographs, and one of the main objects of the invention is to provide a simplified mechanism which is positively interconnected for 5 perfect coordination between concurrently and consecutively related moving parts, so that the functioning of various elements is inherently in correctly timed relation to the functioning of the other elements.

10 Such machines are very frequently installed in public places, and therefore subjected to misuse as well as to a great deal of deliberate abuse. Accordingly further objects of the invention are to provide a construction which is not likely to get 16 out of order, which does not require frequent and accurate adjustment and servicing, and in which replacements which might become necessary are easily made.

Another object is to provide for plural selec- 20 tivity of records from a single coin chute to eliminate duplication of complicated coin detecting mechanism.

Also this invention includes the provision of means for playing records at diiferent speeds.

3 Some standard records are to be played at a normal operating speed, and others at a slower speed, and therefore means are provided for predetermlning the speeds at which the turntable will be operated according to the position in which the .0 records are storedin the magazine.

Also improvements have been made in the gripping means so that the discs are more securely gripped by the transfer mechanism when lifting the records into and out of the magazine, and

placing them on or removing them from the turntable. The record discs are gripped across their diameters, the outer gripping member being mounted on a resilient arcuate arm which encircles the periphery of the discs. Thus very little 0 pressure is needed, variations in the thickness of the discs has no eifect, breakage of the records is eliminated, and the discs may be stored closely in the magaflne.

Another object is to provide an independent 5 motor for the selector and transfer, and to provide means for stopping the operation of the transfer motor while arecord is being played to eliminate noise and vibration.

Another object is to provide a simple, positiveiy acting mechanism for operating the stylus arm, a flanged drum cam being employed to support the arm when oil therecord, to raise and lower the arm, and also to swing the am over the turntable. I

u A further object is to provide an electrical means for initiating the operation of the restoring operations at the completion of the playing of a record so that the arm only has to make an electrical contact, and consequently no power is required from the arm. This is of advantage since construction which is quick and positive in operation and suitable for "self stopping, the main clutch parts being mounted on the power shafts and actuated by a part being positioned in the i5 path of one of the clutch elements to trip, the final power for the disengagement being supplied by the drive shafts.

Other objects and advantages. will become apparent in the following description, taken with 20 reference to the accompanying drawings, in which an illustrative embodiment of the invention is shown.

Fig. 21 is a section of the magazine, taken on the transverse line Il-Ii of Fig. 2.

Fig. 22 is a diagram showing the electrical connections.

The mechanism comprises a skeletonized cast base 25, which is substantially rectangular in plan with one end brought to a point. The record discs 20 are 'placed edgewise in evenly spaced vertical pockets or slots provided by pairs of stamped plates 21 which are mounted in grooves cut in a casting 2|, which forms the base of the magaline 2!, see Fig. 21.

The magazine is transversely sildably mounted on parallel rods 3| and II, which extend through the ears of the assembled plates 21 and notches provided in the front and rear margins of the base casting 28, as shown in Fig. 2.

The rods are fixedly mounted in four upstanding lugs I! provided on the side rails of the rear portion of the base 25. In the drawings the magazine is shown in substantially mid-position, and as containing ten discs with a record on each side thereof, or twenty records. The sixth disc is in position to be removed at the next operation of the machine, unless a record on some other disc is selected, whereupon the magazine will be moved in one direction or the other to bring the selected disc into position. as will be described hereinafter.

On the longitudinal axis of the base and near one end of the same, the right end as viewed in Fig. l, is fixedly mounted a standardized multiple ratio transmission imit comprising a housing ll, having a horizontal driving shaft 34, to which-a turntable motor 35, bolted to the base, is connected; and, projecting from the center of the top of the housing, is a vertical shaft 38 on which the turntable 31 is removably mounted to rotate with the shaft.

On the front of the housing is rotatably mounted a ratio controlling lever ll, Fig. 2, which is held against a stop 39, for normal speed, by a spring ill; and, as will be understood, when the lever 38 is rotated clockwise, as viewed in Fig. 2, to other positions, the speed reduction ratio of the transmission will be changed, so that the turntable will be rotated at a different speed,

A stylus comprising a long arm 4| having a tracing needle 42, see Fig. 1 and Fig. 3, is pivotallymounted on a shaft 43, which projects upwardly from a post ll provided on the rear side of the base 25. The stylus is pivoted for vertical movement on a pair of transversely disposed trunnions I! which are secured to a sleeve It, which is slldably supported on the shaft 43, and

the stylus is partially balanced by means of a weight 41 secured to the rear end thereof so that, when over the turntable, it rests lightly on the surface of a record disc, placed on the table, for tracing the spiral record groove, which causes the end of the stylus to move in toward the center of the table in the usual manner.

On the base at the rear of the turntable transmission housing 33 is bolted a transfer driving motor ll, which is connected by a belt ll to a transversely disposed drive shaft ",which is rotatably mounted in spaced bearing posts Ii and 52, Fig. 8, which project upwardly from the base 25. The inner end of the shaft I has, keyed thereto, see Fig. 8 and Fig. 2, a worm I, on either side of which are bearing posts, or pedestals, l4

and I arranged on the longitudinal axis of the base; and between the post 55 and the magazine are provided a pair of transfer shaft bearing posts I and 51, which are transversely aligned and symmetrically disposed on either side of said axis. At the rear of the base is provided an outboard bearing post It in alignment with the posts it and 51; and in front of the said posts is moimted a selector mechanism frame comprising spaced vertical end plates 58 and it between 1 which is rotatably supported a horizontally disposed selector drum 6i having a shaft 62, the ends of which project through said plates and thus support the drum.

As best shown on the longitudinal section of 1 'Fig. 14, three parallel shafts are mounted in the posts II and 54, a slidable clutch shifter shaft '3; a rotatable shaft 64, immediately above and at right angles to the worm 53 and shaft iii; and a selector and magazine drive jack shaft 65, im- 1 mediately below the worm it, which is positively geared to the shaft 64, to rotate slower, by spiral gears ii and 61, pinned to the respective shafts.

The shaft I is connected for driving the magazine by a line shaft GI which is connected to the 1 gear N by a universal coupling 89; and is connected for driving the drum Si in synchronism with the magazine, as best shown in Fig. 8, through a spiral gear 'lli keyed to a vertical Jack shaft Ii having a worm 12 which meshes with a i worm gear I! fixedly mounted on the medial position of the drum ii. The jack shaft II is rotatabiy mounted in a step bearing 14, formed on the base, and an upper bearing bracket 15 mounted on the post 56; and the gear 18 meshes with the same gear 66 to which the magazine line shaft GI is connected so that perfect synchronism between the movement of the drum and magazine is assured.

As best shown in Fig. 2 and Fig. 21, the left 4 end of the line shaft 68 has a pinion 16 formed thereon which meshes with an endless rack il, fixedly secured to the under side of the magazine base The end portion of the shaft 68 is guided for vertical movement between a pair of i lugs ll, formed integrally on the machine base 25; and the pinion I6 is maintained in mesh with the rack 11, on the upper and lower sides and aroundthe ends thereof, by means of a projection 19, formed on the extreme end of the shaft 4 I, which travels in contact with an endless flange OI, which surrounds the rack 11. Thus as the selector drum ii is rotated, the magazine is moved back and forth, or reciprocated on the rods ll and". The arrangement is such that the 1 magazine has one complete reciprocation for each revolution of the drum.

The drive shaft 50 is normally connected to the magazine and to the selector drum, for driving the same, by a clutch 8i which is similar to 4 the clutch shown in Fig. 'l, and comprises a flanged member 82 positively connected to the driving member, in this instance the shaft ill. The flange I4 is integrally formed on the hub of a worm gear a, which is rotatably mounted on 1 the shaft I4, and is constantly in mesh with the worm i3. Adjacent the flange 84, a collar Ila having a tooth l5, is pinned to the shaft 64. The tooth I5 is engageable by an offset hook lever 88, which is pivotally mounted on the face of the flange ll. In the clutch Ii the lever 86 is normally in engagement with the collar a to connect the worm wheel to the shaft 64.

The lever 88 is yieidably retained in rotative positions by means of a spring plate 88, which is 1 compresed under the head of the pin I. on which the lever It is mounted in the manner shown in Fig. 5. The pin it extends through the flange I4, and the spring plate is positioned on the opposite side of the flange. The hooked portion 0. of the lever I. has an offset cam surface II, and the opposite oifset portion has a cam surface 9!, so that the lever may be rotated to engage or disengage with the toothedcollar a, as the lever is being carried around on the flange .4, by striking one or the other of said oifset cam surfaces ll or 02.

In the clutch Ii, this is accomplished by shifting a sleeve II, which has a projecting flange collar '4 into the path of one or the other relatively oifset portions of the hooked clutch lever. Referring to Fig. 18, the sleeve II is slidably mounted on the shaft 03, and on the sleeve is plwotably mounted a latch lever I, which is normally hooked over a collar II, which is pinned to the shaft I. as best shown in Fig. 16. In normal position, the shaft I is pressed to the left by means of a cam II. which is flxcdly mounted on a transfer drive shaft II. This shaft II is parallel with the motor driven shaft II, and is rotatably mounted in the bearing posts or pedestals 5Q, 51 and Nasbestshown In Fig. 11.

Referring again to Fig. 14 and the subsequent figures on the same sheet, the shaft 8 is normally shifted to the right to compress the spring SI. seated in the bearing post 5|, so that the flange I4 is positioned in the path of engaging cam surface ll of the clutch lever 96, and the worm gear ll is thereby connected to the shaft II and thence to the magazine and selector drum.

The magazine and selector movement is stopped by a lever Ill striking against the end of the latch ii to release the clutch as will be described hereinafter. This permits a light I spring ill, compressed between the sleeve 9! and the collar ll, to expand and move the sleeve 93 over against the bearing post .and position the collar N in the path of the offset unlocking cam surface 91 of the lever I to rotate and disengage the clutch lever from the collar II.

when this occurs. the shaft SI is started into counterclockwise rotation, in a manner which will be described more fully hereinafter, to remove a record from the magazine and place the same on the turntable. This moves the. cam 91 away from the end of the shaft 88. and allows the shaft I to be moved to the left under the action of the heavy spring I, which compresses the lighter spring ill until the latch I again engages behind the collar 90, as shown in Fig. 1B. 'lhe latch is urged into engagement with the collar 90 by a small spring it! which is seated in the reduced portion III of the sleeve 9!. and is comprmed under the left end of the latch 95.

As will be more fully described'hereinafter the shaft 98 is rotated counterclockwise slightly less than a complete revolution to place a record on the turntable. and the cam 91 then stands in the position indicated in broken lines in Fig. 14 until the playing is completed.

When the pllyl is flnished the shaft 08 is rotated back, clockwise, to the normal position shown in full lines in Fig. 14, and thereupon strikes and restores the shaft 81 to normal position with the flange 94 again standing in the path of the engaging cam surface 9i to restore and connect the clutch Ii in readiness for driving the magazine and selector at the next operation of the machine.

The clutches are always disconnected or disengaged when the shaft 33 completes its partial rotation in either direction, by means of lugs H3 and I23, Fig. 11, which are mounted in offset relation on the opposite sides of the driven gear II5. A horizontally disposed lever III is pivotaliy mounted on the upper end of the bearing pedestal II2, Fig. 4, and is provided with a downwardly projecting pin I22 which is engaged in the groove H3 and connects the lever to the The opposite end of the lever I2I is bifurcated and has arms I23 and I24, shown in section in Fig. 11, loosely embracing the edge of the gear H3 in contacting relation with the lugs H3 and I23.

Therefore, referring particularly to Fig. 11, when the restoring movement of the shaft 33 is being completed, with the lever I2I and the rod I34 shifted to reverse the movement of the shaft in the last restoring movement of the preceding cycle of operations, the arm I24 had been against the side of the gear II until the lug I23 moved down into contact with the arm I24 and forced it away from the gear and thus moved the lever I2I into the normal neutral position, which of course stopped the rotation of the gear, leaving the parts standing as shown.

Then when the rod is next thrown into forward position in the cycle of operations, to the right from neutral, the finger I23 is moved over towards the adjacent side of the gear and the lugs move up away from the fingers and around with the gear and until the lug II3 comes up from below and contacts the finger I23 to move it back to the right and restore the lever I2I and rod I34 to neutral position and stop the f w r movement of the shaft 33 until the rod I34 is shifted into reverse position to effect the reverse andrestoring movement.

The construction of the transfer mechanism which will now be described, is particularly shown in Fig. 2, Fig. 11, Fig. 14 and Fig. 15, and the rear elevation of Fig. 19.

In alignment with and immediately above the shaft 33 and in the bearing pedestals 53 and 31 is rotatably mounted a barrel I23, shown in section in Figs. 11, 14 and 15, which has an axial bore I23 extending through its plntles I21 and I23, and has a transverse bore I23 in the portion between the bearings.

In the transverse bore I23 are slidably mounted gripper support members comprising a sleeve I33 and the stem I3I of a button or disc member I32. The sleeve I33 is formed integral with a rectangular, outer finger supporting block I33 which is guided between the cheeks of the bearing pedestals 53 and 51 to support the arm I34 upright in the normal position of the transfe the arm I34 being fixedly secured to the block I33. The cheeks of the bearings are cut away at I35 to allow the block to rotate in the forward positions of the transfer in which the arin is rotated selectively ninety degrees to the right or to the left to lay the discs fiat on the turntable.

A small rod I330 extends centrally through the sleeve I33 and rigidly connects the button member I32 to an arcuate grooved inner record gripping block I33. A sleeve I31, pinned to the rod I330 and gripper block I33, is provided, which extends slidably into the bore of the sleeve I33 and is splined thereto by a key I33, seated in the sleeve I31, for preventing relative rotation between the inner gripper I33 and the outer gripper I33, which is fixedly mounted on the outer end of the arm I34, Fig. 2.

Normally the outer gripper is supported by a bar I33a, rising from the base 23; and in playing position the block I33 rests (I! an upstanding bar I33b which is bolted to the mosite end of thebaseattherightofthenrrntshle.

The gripper blocks I33 and I33 are drawn together to grip a record disc by aspring I43 which is compressed between the inner and of the sleeve I33 and the bottom of the bore in the sleeve I33; and normally the grippers are separatedbymeans of a wedge plunger Ill. The plunger is slidably disposed in the axial bore I23 and has a bifurcated and reducedend portion I42 which embraces the rod I330 and extends between the inner ends of the sleeve I33 and the stem "I, so that, when the plunger is forced inwardly, the wedging surfaces I43 separate said inner ends and open the grippers to release the record.

In Fig. 14 the above parts are shown in normal condition, with the gripper open: and in Fig. 15, the plunger I4I has been withdrawn to allow the gripper to close, under the actiim of the spring I43, and engage the periphery of a record disc. The arcuate arm I34, Hg. 2, is parallel with and encircles the discs in the magazine. This permits close spacing of the discs; and the grooved gripper blocks are in the form of segmental arcs so that very little pressure is required across the discs to hold them very securely.

As clearly shown in Fig. 2 and Fig. 11, the transfer drive shaft 33 has, fixedly secured thereto, a face cam I45 for the operating of the plunger Hi to close the grippers in the initial movement of the shaft 33 in either direction by moving the plunger MI, and to open the grippers at the ends of either movement, so that when the transfer is at rest with the arm I34, either over the magazine or in the forward position encircling the turntable, the grippers are open, but before the transfer barrel I25 starts to rotate in either direction the grippers are closed to grasp the disc.

This is accomplished by means of a bell crank lever I43 which is pivotally mounted in a bracket I4I, securedto the pedestal 51. The lever I43 has a bifurcated end I43 whichengages in a groove I43 provided in the outer end of the plunger MI, and has a ball portion I53 which is engaged in the groove I5I of the cam I45. As shown in Fig. 13, normally the ball I53 is in the radially remote portion of the cam groove and posiflons the bell crank lever I43 for moving the plunger in, to separate the grippers. Then in about the first ninety degrees of the forward rotation of the shaft 93, counterclockwise, the ball is moved into the one hundred and eighty degree dwell portion of the cam groove which is closer the axis of the shaft 33. This rotates the bell crank I43 clockwise and withdraws the plunger III for gripp ng the discs until the last portion of tin shaft movement in which the ball I53 travels back to the remote portion of the cam groove and reopens the grippers to release the disc. In the reverse movement of the shaft in which the disc is lifted from the turntable and returned to the magazine, the plunger operation is automaticalLv reversed to grip the disc before it is lifted, and to release the disc when it is back in position in the magazine.

The transfer barrel I25 is rotated, after the grippers are closed, by means of a mutilated gear I52, Fig. 2, keyed to the end ofthe shaft 33 which projects forwardly the bearing pedestal 53; and this gear meshes with amaflng mutilated gear I33, pinned to the outer end of the barrel pintle I23. The gears I32 and I33 are provided with lntermeshing gear teeth on substantially a little less than one-half their circumferences so that in the first quarter of the movement of the shaft ll time is allowed for the grippers to close and grip the adjacent disc in the magazine. During the next half of the movement the gear teeth engage and the barrel is rotated to lift the disc out of the magazine and swing the disc onto the turntable; and during the last quarter of the movement the cam ill' opens the grippers to release the-disc and leave it on the turntable until the playing is finished. By reversing the movement of the shaft ll, these operations are auto-'- matically performed in reverse order to restore the disc to the magazine.

During the turning movement of the barrel and transfer parts, and while the block I" is out of engagement with the checks of the bearing pedestals II and 51, the button II! is eccentrically engaged by one or the other of a pair of selectively projected plungers ill and ill, slidably mounted in a plate ill fixedly secured to said pedestals. to turn the gripped record disc into the horizontal plane of the turntable, or back into the vertical position for insertion in the pockets of the magazine.

The spherical face of the button I32 is provided with angular grooves ill and I" which extend parallel to an axial line between them and inward from the margin, and then at right angles again outwardly, Fig. 5. 7 Then as the button swings past the plunger-s in the forward movement of the transfer, the projecting plunger enters one side of its groove, strikes the angle and rotates the button, and transfer arm, laterally ninety degrees and then passes out the other tangentia] portion of the groove. During the return movement, the plunger t. through the groove in the opposite direction and turns the arm back to the vertical position.

The plungers Ill and III are slidably sup-' ported, Figs. 14 and 20, in the upturned end portion ill of the plate. Ill, and the lower ends of the plungers are pivotally connected to oppositev sides of a rocker plate I. which is centrally pivoted to the supporting plate I". The lower edge of the rocker plate I is centrally recessed to accommodate the angular end of an operating lever I6 I, medially pivoted on the plate I", below the rocker plate, and said angular upper end is formed so that the rocker plate is locked in either position in which it is moved by moving the lower end of the lever Ill.

Thus, as best shown in Fig. 20, one of the plungers ill or I" is projected into the path of the button II! and the other withdrawn, according to the position of the lever Ill. The final movement of these parts in either direction is affected by means of a spring I62 which is extended between a lug I", formed on the upper portion of the plate I", and a pin Ina secured in the lower portion of the lever ill to give the parts a "snap over" action as the spring passes over the line intersecting the pivotal axes of the rock plate and lever.

At the ends of the movements of the magazine, in either direction, the lower end of the lever III is contacted by lugs I or I" provided on the sides of the magazine base. see Fig. l and Fig. 2. andthe relative positions of the plungers is thereby reversed. Therefore, during one directional movement of the magazine the records on one side of each side of the discs will be selected by turning the corresponding faces of the discs up on the turntable; and in the opposite movement of the magazine, the records on the opposite sides of the discs will be selected.

The stylus 42 is also permanently connected for operation to the shaft so that its movements are positively coordinated with the movements of the transfer to swing the arm over and lower it onto the outer portion of the record when a disc is placed on the turntable. and to raise and swing the arm away from the turntable before the disc is removed.

The base I" of the stylus arm Ii has a forwardly projecting arm portion I", Fig. 3, which rides on the-flange III of a cam I" which is fixedly mounted on the rear portion of the shaft SI, particularly shown in Figs. 3, 4 and 11. The flange I" normally lifts the stylus clear of the turntable. but has a flattened portion I10, Fig. 3. which lowers the arm in the extreme forward rotation position of the shaft II. clockwise in Fig. 3, and the arm is swung over the. table by means of a downwardly projecting pin lli, secured in the arm I", which pin is engaged in a gaove I12 formed in the The groove has a circumferential portion near the outer end of the cam for holding the stylus in normal position away from the turntable, as best shown in Fig. 1. The groove then extends helically on the surface of the cam to swing the arm over the table, and terminates in a widened portion ill, which leaves the pin free to move as the stylus moves toward the center of the disc in playing a record. As is manifest, during the return-or reverse movement of the shaft II, the stylus is first lifted. and then swung back out from over the turntable.

' The selecting operations, mentioned above, are controlled as follows, particular reference being made to from Fig. 5 through to Fig. 12. As described, the selector drum Ii is rotatably mounted between end plates 50 and III, which are fixedly secured to the base, and the drum is positively connected for rotation with the movement of the magazine carriage to make one complete revolution with each complete reciprocation of the magazine.

The surface of the drum is provided with a helically arranged row of regularly spaced projecting selector lugs ill, extending the length of the drum, and two relatively reversed semicircumferential helical rows of playing speed control buttons I", which are spaced between the adjacent lugs, as particularly shown in Fig. 10.

Between the selector frame plates 69 and 60 are fixedly mounted a slotted selector lever support bar I18, Fig. 8 or 11, a slotted selector latch support bar I": and a selector lever spacing comb ill, in which is suitably supported a series of selector units corresponding to the twenty sides of the ten discs.

Each selector unit comprises: a selector lever ill which projects through a corresponding slot in the comb I", and has its lower end pivotally connected to a lever I", which is pivotally mounted in the bar III; a depending latch lever IBI, which is pivotally mounted in the bar Ill: and a solenoid ill, the solenoids being arranged in two rows to save space laterally.

The selector levers i1! have projecting arm portions I 83 for engagement in notches ill provided in the latches ill; and the corresponding levers and latches are connected by springs I85. so that, in normal position. as shown in Fig. 8. the selector levers are drawn upwardly and P riphery of the cam lockedawayfromthedrumandoutofengaging relation with their correspondinglugs I'll.

Whenasolenoidisenergiaed,theeorrespondlng latch is attracted and selector lever. A pin Ill. secured in the lever.

contactswith the under side of the comb IIl'so into the path of the corresponding lug I'll, as

enters the notch Ill and strikes the upper end of the notch when the lever is free from the lug and pulled upwardly by the spring. This restores the selector parts to the normal locked position.

Rotatably mounted in and extending between the frame plates are provided a starting switch operating shaft Ill, in front of the row of selector levers, and a clutch operating shaft Ill. The shafts are provided with lateral vanes Illa and Illa, which project into cooperative relation with the levers so that, when any of the selector levers are first released, the switch shaft III is rotated slightly clockwise; and when a lever is pressed downwardly, as shown in Fig. 9, the vane Illa of the shaft Ill is contacted by the lower end of the lever, Fig. 9, and the shaft Ill is rotated counterclockwise.

On the outer face of the frame plate ll, Fig. 5. is rotatably mounted a mercoid motor starting switch Ill which is normally held open, but is urged to close by means of a spring I" which is connected to the switch arm Ill and anchored to a pin Ill, fixed in the plate ll. The switch is held open against the action of the sprrlng by the detent plunger lllb, Pig. 8. which yieldably holds the clutch shifter rod Ill in normal, or shifted positions.

The connection to theshifter rod Ill is made as follows: An upwardly extending curved lever Ill is pinned to the outer end of the shaft Ill, and ahorisontally disposed lever Ill, having a tooth I", is pivotally connected to the upper end of the lever Ill. A vertical clutch shifter lever Ill, Fig. 5, is pivotally mounted on the base II, and has a pin Ill in the upper end thereof, which is engaged in the medial groove Ill of the shifter rod Ill; and the lower end of the lever Ill is pivotally connected to the lever Ill by a shifter bar Ill, so that the shaft Ill and parts connected thereto, such as the lever Ill and vane Illa move with the shifter rod Ill, and are thereby also yieldahly held in neutral, forward, or reverse positions by the detent lllb. Accordingly, In the normal neutral position, the switch is held open, against the action of the spring "I, by the tooth ll! of lever Ill, which is engaged with a tooth Ill, provided on the upper portion of the switch arm Ill, as shown in Fig. 5.

when a selector lever is first released and the shaft Ill thereby rotated clockwise, the lever Ill is lifted out of holding engagement with the switch III by aplate III which is slidably mounted on the frame end plate ll and pivotally connectedtoacrankarm Ill whichispinnedto the outer end of'the mm m, the parts being then moved into the positions shown In Fig. 6.

From this, it will be seen that the starting switch is not affected when the shifter parts are moved into forward position 1', nor when the parts first return to neutral position K; but, when the parts shift from neutral to reverse R, the lever Ill is moved to the right and is then in position to again engage with the switch lever tooth Illl when the parts return to neutral, providing all of the selector levers have been restored and the slide III has been allowed to drop back down into normal position, shown in Fig. 5, but if one or more of the selector levers are still in released condition and not restored, the final restoring movement from reverse to neutral will not reopen the starting switch Ill, and the cycle of operations will be repeated.

An auxiliary switch Ill, normally closed, is provided for cutting out the transfer motor ll during the playing of a record. This switch is carried by an arm Ill, which is pivotally mounted on the outer face of the left side selector frame plate ll, and is urged into closed position by a spring Ill, anchored to the plate ll. This is particularly shown in Figs. ll, 12, and, looking from the opposite direction, in Fig. 19.

A crank arm I" is fixedly secured to the outer end of shaft Ill, and a horizontally disposed latch lever Ill is pivotally connected to the upper end of the crank arm. The lower edge of the outer portion of lever Ill is notched to provide an angular surface Ill and a tooth Ill for engagement with a cooperative tooth III provided in the upper end of the switch lever or arm Ill. The normal position is shown in Fig. 11; the position when the clutchoperating parts are shifted to forward is shown in full lines in Fig. 12; and the playing position is indicated in Fig. 19, the clutch parts having been moved from forward back to neutral positions.

Thus in normal condition, the latch Ill is disengaged from the switch lever, the outer end of the latch being at that time supported by a plate III which is fixedly mounted on theedge of the frame ll. When the clutch shifter parts, including shaft Ill, are moved to forward position, which is to place a disc on the turntable, the latch Ill is moved to the left, Fig. 12, and the tooth Ill is hooked over the tooth I I I, the switch Ill being still held closed by the spring Ill. Next the clutch parts are moved back to neutral, and the switch is thereby opened, as shown in broken lines in Fig. 12 and in full lines in Fig. 19. This stops the transfer operating motor during the play When the playing is stopped, in a manner which will be described hereinafter, the shaft Ill is moved from neutral, N, to reverse, R. This moves the latch Ill to the extreme right, Fig. 12, and the end of the latch is cammed upwardly by the angular surface Ill riding on the edge of the support plate I ll, and the latch is disengaged from the switch lever, which, of course, allows the spring Ill to rotate the switch back to closed position. This restarts the transfer motor to return the disc to the magazine. In the final clearing movements, the shaft and latch Ill, is moved back to the normal, neutral position.

As mentioned above, some discs carry records which are to be played at slower speeds, and for providing a machine in which both kinds of records may be used, a plurality of manually operable set levers Ill are provided. In a machine for playing twenty records inscribed on the op- 15 controlled by the set levers 2 I ii in l lg. 1. Hg. 2, Fig. 8, and Fig. 11. is attached to the speed control arm variable speed on ll. Fig. is preferably connected to the lever extent across the'inner side of the trans- Inechaninn frame and adjacent the outer of the mutilated transfer drive gears in I. left end of the bar is guided and slidahly supported in a slot 2" provided in a downwardly bent nation 2" of a horizontally dhpund frame plate 2", Fig. 8, which is fixedly moun on the selector frame members 59 and the bar is provided with a tooth projcction 2 I which. when the end of the bar is raised,ispositionedinthepathof apln 22f ted in the face of the gear I. Accordingly when the gear Ii! is rotated clockwise, Pig. 2. to transfer a disc to the turntable. pin 22l normally mises the tooth 22., and arm 28 remains in normal position. but, when lever 22. b raised," the pin 22l in the final movemmt of the transfer will engage and move the bar 2i6 to the left the arm I in a position for oba flower or different speed ratio. Then, the tramfer moves reversely. the bar 2| is and the spring I returns the arm II a more usual meed.

'lhe levers 2| extend through slots provided surface 224 at a greater radial distance from the shaft. Said surfaces of each lever are in cooperative contacting relation with an irregularly formed floating plate 225 for lifting the bar 2". Each of said plates is also in cooperative relation with a corresponding pair of the buttons "I, mounted on the drum, so that a button moves into cooperative relation with each lever as the corresponding discs are opposite the transfer.

A rod 22. is rigidly supported by ears 221. depending from the plate 2", and this rod extends through slots 22' for loosely supporting the inner portions of the cam plates 225, which are provided with fingers 229. which project under the bar 2'6. The outer ends of the plates 225 are urged upwardly by springs 23! to maintain the plates in contact with the cam surfaces of the levers 2|.

Thus when the levers are moved forward. as shown in Fig. 11,. the corresponding plates are in contact with the lower earn surfaces 222. and the plats are held upwardly so that their lower areuate surfaces 23l are out of contactual relation with the corresponding button lugs I15. And when the levers set in the other position, shown in broken lines in Fig. 11. the higher cam surfaces 22! are brought into contact with the plates. This lowers the rear ends of the plates and provides a fulcrum so that the lugs lI5,- in the rotation of the selector drum it. will strike the arcuate lower edge surfaces 23l and raise the innet ends of the plates to lift the bar 2l6 to place its tooth 22. in the path of the gear pin 22 so that the discs corresponding to the levers 2l5 wbidi have been set in the broken line position willbeplsyedataslowerspecmtberatio oitbe turntable ward movement of v For canceling selections which have been made but not yet played. a solenoid 232 is provided which is fixedly mounted on the bearing post It, see Fig. 5, which functions to move a clearing bar 282 to the left in said flillre. and return the selectively released levers "I back to normal position in which they are again latched by the latch levers ill, the clearing bar contacting with fingers 224,-provided on the upper ends of the levers I'll, see Figs. 8 and 11.

The bar 282 has crank arms 2" which extend upwardly and through the selector frame plates II and II. to. p votally support the bar, and the arm Ill adjacent the plate OI has an upwardly projecting lever portion 2" to which is pivotally connected a horizontally disposed bar 231. bar 281 projects over the solenoid 232. and extends through a slot 2 formed in the upper end of an oscillating lever 22!. The lower end of the lever 28! is pivotally supported by the post ll. Fig. 14, and the lever is urged into contact with an eccentric cam "I by a spring 2", Fig. 5. The com III is keyed on the outer end of the shaft I, so that when the shaft is rotated during the operation of the transfer the lever 23! is continually moved back and forth.

The bar 221 has a notch 2" in the portion which extends through the slot 28., in the upper end of the oscillating lever 22., so that when the solenoid 222 is energized to attract and pull the free end of the bar 231 downwardly. the lever 230 is engaged in the notch 242 and the bar2l'l moved to the right to swing the universal bar 233 against the selector levers and restore the same. The free end of the bar 221 is urged upwardly and normally into contact with the upper portion of the lever notch 23' by a spring 2", extended between the bar and the arm 23', and a spring 2 which is stretched between said arm 2" and a plate 2" which is fixedly mounted on the outer edge of the frame plate Bl.

The plate 2" also serves to guide and limit the upward movement of I96 which projects through an elongated slot in the plate. The spring 2 urges the arm 2" into contact with an abutment plate 2 which is fixedly mounted on the frame bar I".

As best shown in Fig. 14, the lever ill, for tripping the clutch II and stopping the operation of the selector drum and magazine. is pivotally mounted on the bearing post It. and the lower end of the lever has a slotted pivotal connection with the medial portion of the operating bar 2 of the clutch shifter train. Accordingly. when a selector lever is pressed downwardly, and the shaft I rotated counterclockwise, moving the bar 2" to the left. the selector clutch ll is disconnected and the forward transfer clutch I" is connected to start the transfer mechanism into operation to place a disc in playing position.

After the shift for forward movement of the transfer the bar 2 is next moved back to the right, to neutral position. by the contact of the lug Ill with the underside of the horizontal lever HI. and the forward transfer movement is stopped by the disengagement of the clutch I05. At the completion of the playing. the bar 2" is moved to the right, reverse position R. by means of a solenoid 2". The solenoid 241 is fixedly mounted in a lug 2". projecting upwardly from the base 28, and has an armature 249 which is The pivotally mounted in a bracket III which is fixed 7 tion, to tberlahtttoconnectthe operatim the tramfer reversely to restorethereemddhetotbe Atthe compleflonoltheredoringtthebarfll connectedtheretoare lead III of a 110 opposite supply lead 2" to oneterminal of the II.

Thus when the switch Ill iseimedbothmotorsareputintooperation; frmn will! line. wire II! to both motors, from motil- 35, wire I, switch Ill, wire I". back to the my line ill: and from motor 48, wire Ill, switdi Ill, wire "I, switch ltl, and returnwirelll' mwhentheswitch Illis opened, with the switch III closed, the transfer motor is and when the switch m is opened. both motors are disconnected.

A step-down tramfonner ill is connected across the supply lealb Ill and iii, and supplies a low voltage current to control circuit lead wires 2" and 2".

A coin operated switch It! initiates the operation, and seleetlons'of records are made by a manually operated cmnmutator 283, one side of the coin switch 2'2 being connected to the lead "I, and the oppmite side of the switch 202 being connected to the commutator arm "I by wire I.

The commutator as is provided with a plurality ts 2 with the records stored in the and each segment isconnectediuawire ltttothe liveterminals of the correlated selector solenoids I. The grounded tu'milmls of the solenoids II! are connected by wire ill to the opposite control circuit lead wire 2.

Thus when a coin is manually inserted in the coin chute Ill, and the wheel 28! which has peripheral pockets to receive the coils is manually operated to came the coin to close the switch III, the positim of the commutator arm will determine the record which will be selected, by energizing the selector solenoid ill and releasing the lever I" which is related with said record. This circuit comm-ices supply wire ltl, switch 262, wire I, commutator arm I, the contacted segment 265, its wire 2, its solenoid III, and the common return wire 2" to the opposite supply lead 2.

The 2!! may be operated remotely by a push button 21!; and a push button branch I, switch 3", wire 2, to "I.

I" is provided for alternate operation of the transfer reversing solenoid 241. A terminal of each of the solenoids 232 and 2" is permanently connected, by interconnecting wire Ill and wire 2", to the lead I; and the opposite terminal of 8 the solenoid ll! is connected by wire "I to the push button switch I'll, and thence to line It! by wire ill. The opposite side of the reversing or playing stop solenoid 241 is connected by a wire III to one terminal of the push button switch I", and by branch wire I to one side of the stylus switch ill. The opposite side of the push button switch as is connected by wire III to the opposite line ill, to which the opposite side of the switch III is also connected by wire 2. Thus the stylus arm switch 30. and the push button switch III are in parallel relation for energizing the solenoid I"; from solenoid wire Ill, switch 219,.wire It! to line 2"; and from wire I,

To review the operation, the commutator It! is manually rotated and .set to select a desired record. Then a coin is inserted in the chute and the wheel it! operated to close the coin operated switch 202. This energizes the selector solenoid connected to the contacted commutator s 8 ent.

It will be observed that several selections may be made at one time; and the selected records will be played in the order in which the corresponding fingers I'll make contact with the released selector levers, since the motor switch III remains closed as long as one selector lever stands released.

When any one of the selector magnets II! is energized, it attracts its latch itl and releases its selector lever I'll. Thereupon the spring it! rotates the lever clockwise to the inner end of its slot in the comb ill, and towards the drum. This presses the vane Illa to the right and rotates the shaft III to raise the slide III and disengage the latch lever llt from the switch Ill so that the spring lfl'will move the switch to its closed position and thus start the two motors into operation. Accordingly releasing a selector lever starts the two motors and initiates the cycle of operations.

At the-beginning of the cycle, the transfer clutches II! and I" have been disengaged, and the selector clutch II is in engagement. Then the operation of the transfer motor, in rotating the shaft Bl, starts the selector drum and magazine into coordinated operatiomthe worm It, on shalt I, being in mesh with the worm gear ll, which is connected to the shaft '4 by the engagement of the clutch ll. The shaft 84 is rotatively connected to the gear wheel 00, which is positively connected, through the line shaft", for driving the magazine, and through gear ll, meshing with the gear wheel 68, through worm l2 and worm 13 for rotating the selector'drum, see Fig. 8 and Fig. 14.

The movements of the drum and magazine continue until the finger I'll corresponding to the released lever contacts with point It! and forces the lever downwardly to a position where the angular surface below the point forces the lever out of engagement with the finger.

In the downward movement the lower end of the lever I19 contacts the vane I891: and rotates the shaft I to move the clutch levers and mechanism connected to the shaft into. forward position where these parts are held by the detent lltb. This moves the lever III to unlatch the lever 85 and releas the selector clutch ll,

is i

and shifts the latch lever 200 to theleft in position to engage with the switch 204;.and moves the shifter rod I04 to the right to position the flange H1 in the path of the offset'portion of the hook lever of the clutch I05. When said portion strikes the flange II1, the clutch I is en- Based to connect the bevel pinion I01 to the shaft 50 and start the transfer shaft 00 into operation, clockwise, as viewed from the front of the machine on which the selector mechanism is mounted.

The energization of the selector solenoid is only momentary and the lower end of the latch lever "I is immediately moved back into engag ing relation with the lever I by the spring I05, so that when the lever becomes disengaged from the drum finger I14 and is drawn upwardly it is rotated back into the locked position and thereby restored to normal. This restoring movement permits the vane I000 to move back to the left and allows the slide 202 to move down and lower the bar I06 into engaging relation with the motor switch IOI, unless other selector magnets have been energized by the insertion of coins and corresponding selector levers are standing in released position awaiting contact with the drum fingers.

However, upon the restoring of one selector lever, the cam 01 on the transfer shaft 00 is moved out of contact with the end of rod 0;. and the shifter mechanism for operating the clutch 0i is conditioned for resetting the latch lever 05 being reengaged with the collar 06.

v The lugs I14 are arranged so that the switch II is openedandthe drum and magazine stopped when the disc having the record which corresponds to each lug is opposite the transfer mechanism and positioned between the gripper segments I00 and I05. Making the selection between the records on the opposite sides of the discs is determined by the direction in which the magazine is being moved by the contactsof the magazine lugs I04 or I05 with the trip lever IOI.

Thus when the magazine is being moved to the right, as viewed in Fig. 5, the lower end of the.

lever IOI had been moved to the left and the lug, I55, projected into the path of the grooved hand side of the records in the magazine, and

lugs eleven to twenty-one represent the records on the right hand side. Space is provided between the tenth and eleventh lugs and after the twentieth lug to allow for the rotation of the drum while the pinion is working around the nds ofthe rack- 1i. I

Before the teeth of the mutilated gears I50 and I53 mesh to start the rotation of the selector barrel I to lift the arm I34, the gripper cam I45 rotates the bell crank lever I clockwise, Fig. 5, to withdraw the plunger HI and allow the segments I00 and I0! to be drawn together by spring I40, see Fig. 15, and grip the periphery of the record disc.

Next the intermeshing teeth engage and the gear I50 rotates the gear I53, Fig. 2, clockwise to place the record on the turntable, with the outer gripper segment "0b resting on the support I30. As the teeth pass out of engagement the cam I rotates the bell crank lever counterclockwise, and forces the plunger back in to wedge the supporting members apart and separate the gripper segments to leave the record disc resting on the table.

In the forward rotation of the transfer shaft 00, the stylus arm pin "I is first in the circumferential portion of the groove in the cam I which is fixedly mounted on the shaft. the disc is placed on the table, the helical portion of the groove engages the pin and the arm is swung over the edge of the disc and lowered, by the fiat surface I10 of the cam flange I00 moving into cooperative relation with the stylus base projection I01.

This movement of the stylus of course occurs during the period in which the gripper is being opened; and when the stylus is lowered the pin I1I is free to travel in the widened portion I13 of the cam groove. At the completion of the forward rotation of the shaft 00 the lug II9, on the gear wheel II5, moves up into contact with finger I23 of the clutch lever I2I and returns the lever, the shifter rod I04, and the remainder of the transfer clutch operating levers to the neutral intermediate condition. In the neutral position both collars H1 and I I0 are placed in the path of the ofiset portions of the hook levers of the clutches I05 and I00. Accordingly the lever of clutch I05, rotating with the shaft 50,

When

strikes the flange collar H1 and the clutch is thereby disengaged and the rotation of the transfer jack shaft is stopped.

In this return from forward to neutral positions, the latch bar 200 is moved to the right, and having been hooked to the switch carrying lever 205 in the forward position, the transfer motor switch bulb 204, seeFig, 12, is rotated clockwise into open position. Thus the transfer motor is stopped, leaving the turntable motor, running for playing,- the record. This stops the operation of all of the transfer machinery during the playing and eliminates the noise and vibration and prevents distortion and interference with the reproduction of the sounds recorded on the disc.

When the needle moves into the spiral grooves I of the inner portion of the record, the stylus arm moves over the contact plate 30Ia of the switch 300. This closes the control circuit, wire 200, playing-stop solenoid 241, wire 203, branch 204, "switch 000, and wire 200 back to the supply line. The solenoid 241 then attracts its armature 240 which is connected to the bar 200, and the train of connected shifter bars and levers is moved from neutral to reverse position. This closes the transfer motor switch 204 and causes the engagement of the reverse clutch I00, thus starting the transfer jack shaft 00 into rotation to reverse the operations described above of the parts which are operatively connected thereto, lifting and swinging the stylus away from the turntable and jack to normal position, at the same time gripping the disc; lifting the record off from the turntable and rotating it back into the vertical plane, replacing the disc in the magazine and releasing the same. Also this reverse movement of the shaft 00 restores and causes the reengagement of the clutch 0|, and the shaft is stopped when it again reaches its normal position by the forward lug II! on the transfer jack shaft gear moving bringing the machine to rest, unless, as mentioned above, some of the selections remain unplayed. In that case the final movement of the latch bar III to the left will be prevented from 8 8 8 the switch IOI by the slide being held in elevated position by the released selector lever,

B and the cycles of operation will be repeated until all the selector levers are restored.

' In this manner a simple and rugged mechanism is provided for performing the manifold operations required. The selecting movements are 10 controlled by one clutch and the different parts are maintained in perfect timing relation by being positively geared to the clutch.

Positively connecting the stylus arm, the gripper and the transfer to one shaft and providll ing a reversing clutch means for turning the shaft one way to present a record, and then turning the shaft hack to restore the record simplifies the mechanism and ensures perfect coordination of these parts, which is not affected by wear.

' The speed'setting permits the use of fast and slow speed. records in the same machine: and selections may be canceled before they are played;

Since electrical phonograph "pick ups are used. the stopping of the transfer mechanism and I motor tends to clarify the reproduction.
