Application 'tiled October 10, 1917. Sel-iai No. 195.697.

To all whom. it may concern:

Be it known that I. JoEL G. LEMMEm a citizen of the United States, residing at Philadelphia, in the State of Pennsylvania, have invented a certain new und useful Improvement in Tahiin Machines, whereof the followingy is a specification. reference be ingr had to the accompanying drawings.

My invention relates to sound recording and reproducing machines, including gramo4 phones. and xrraphophones; and particul-.trly feed mechanism for sound boxes of such machines adjustable to autoin-.itically repeat their cooperation with a given sound record,:

at the will of the operator.

As hereinafter described. my invention is specifically adapted for such machines Aarranged to cooperate with fiat disk records, and haring sound conducting tubular arms or horns which move with the sound boxes, and are so constructed and ar'anged that repetition of the cooperation oi' the sound box with any given record is consequent` upon such movement, to an adjustably predetermined extent.

In each of the embodiments of my invention chosen for illustration herein, the op eration of the feed mechanism aforesaid is initiated b v electr-'lealiy actuated means.

I find it convenient to illustrate and de scribe my invention herein in connection with a graphophone of the type known commercially as The New Edison Diamond Amberola, and also in connection with a `n'annnihone of the type known commercially as a Victor Talking Machine." However, it is to be understood that I do not desire to" limit myself to such specilic embodiments of my invention, which includes the various novel features of construction and arrangement.hereinafter morev definitely specified.

It may be observed that although the two embodiments of my invention chosen for illustration herein are specifically diierent in their details of construction;v they each include means to variably piedetermme the initial and terminal positions of the respectiyc sound boxes with reference to' g1ven sound records, in combination with a single rotary cam constructed and arranged to antomatically litt the sound box from cooper ativc relation with the record when it reaches a varia-hiv predetermined terminal position and to t )cn return the sound box to its initial position and again lower it .into cooperative relation with the record; said cam havingthe'y capacity to shift said sound box, throughout thc maximum rangfxfof its` movement, by frictional engagement with a cam late arried with the sound box. but itse ectivc capacity is adjustablv variable in accordance with variations in tie extent oi diii'ercnt sound records.

In the drawings: Figure I is a plan vieu of the Edison graphoplmnc aforesaid, having .a convenient embodiment of my inven tion in connection therewith.

Fi l. XIII is a fragmentary plan view of the eed cam and the mechanism, shown at the right hand side .of Figs. I, II and III, whereby said cam is .tctuateii.

' Referring to the form of my invention l ing inclosing a graphophone including the tory diaphragm and carries the stylus 7,y

indicated in Fig. I1, arranged to traverse a' groove in a record 9 on said turn table and automatically shift said boxtoward the axis of said table. The amplifying horn 10 is rigidly connected witlrsaid tone arm i and with the vertical shaft 12 which forms a pivot upon which said box 5, arm (l and horn 1.0 oscillate together.

As it is the purpose of my invention to shift said sound box from its terminal position upon any record to its proper initial position with respect to such record; it is important to note that there is considerable variation in the radial position of the initial and terminal portions of sound record grooves in records of the same nominal size, and, therefore, 1 Jrovide stop mechanism which is adjustably variable to predeterinine the initial and terminal positions of the sound box 5 with reference to any given rec-ord. y

The adjustable initial stop lever 13, indicated in Fig. I, is arranged to limit the initial position of saidbox 5 in coperation with said record 9 at the outer limit of its movement with respect to the axis of said table 2, by the curved portion 14 thereof provided with the padded inner face 15 vto encounter the vertically extending of said horn 10 as indicated in Said initial stop lever 13 is fulcrumed at 17 in connection with said table plate 4 and is flexible so that its free en d may be vertically shifted to and from en the toothed rackv 18 which is rigidly corinected with said casing 1. VOf course, said stop lever may be thus manuallyjad'usted` to any position corresponding wit\ the greatest radial extent of the record-Fgioove 1n said record 9; or it may be adjustd in correspondence with the radial position of any other point in said record groove at which it is desired to initiate or resume the coperation of said stylus 7 with said record groove.

As said sound box 5 is carried across the record 9 in cooperative relation therewith and toward the ax'is of said table 2, said horn 10 is swung in the direction of the arrows indicated in Figs. I and-III; its

terminal position being indicated in dotted lines in Fig. III, correspondin A with the terminal position oflsaidv sound x 5 with reference to said record 9.; and the ad,

instable terminal stop lever 20 is arranged to variably limit the terminal position of portion ig. I.

gement' with said box 5 by variationlin the radial extent of the stop arm 21 of said lever 2C which, as indicated in Fig. II, is upturned to encounter theedge of said sound box 5. Said stop arm 21 has the gear racli 22 mounted to slide transversely in the hood 23 on said lever 2() and is adjusted by rotation of the gear 25 by the knob 26, both of which are fixed-on the shaft 27 journaled ,in said lever 20. Said leverhas the fulcrum shaft 28, indicated in, dotted lines in Fig. II, rigidly connected therewith but'mounted to turn in the base bearing 29 which is fixed on said casin 1 by the screws 3Q indicated in Fig. I. i aid stop level' 2O is normally held in operative position by its springl which extends from said base 29 in engage` ment with a notch 32 in said lever as indicated in Fig. II. However, when it is dcsired to render said lever 20 inoperative; it may be manually turned in the direction of the arrow marked thereon Iin Fig. I; such movement automatically disengaging said spring 31 from said notch 32 and permitting it to engage the notch 34 to hold said lever in inoperative position until manuall returned.

though it is not essential; I prefer to provide said stop arm 21 of said lever 20 with the pointed index 36, shown in Fig. I, for convenient registration with the particularpoint in the record roove at which it is desired to terminate t ecoperative relation of the stylus and record and shift the sound box to repeat the operation. Therefore, itis to-be understood that the construction and arrangement of said terminal stop mechanism is such that it may be precisely aldjusted in accordance with the radial position of any selected terminal point of the sound groove in anyfrecord 'caypable of cooperation with the mechanism above contemplated so that whenfsaid sound \box and h orn reach such-'terminal point,

The automatic feed mechanism which is arran ed to raise said h orn 10, tone arm 6 and t e box 5 from their terminal position, shift saidvbox away from the axis of said table 2 and lower them to their initial p'osition, includes the cam 42 shown in Figs. II, III and IV, which is rigidly7 connected with the cam shaft 43, mounte to revolve on a horizontal axis and axially reciprocates in the frame 45.- During its operation,

frictionally v en-4 said cam 42 is'arranged to gage the under surface of the cam plate 48, which is rigidly connected with said shaft 12 in the position shown in Figs. II and III.

However, Said cam l2 normally remains atationary during the cooperation of tl e sound box with the record; that is to eay, while the sound box is traverainiir the record from ita initial to its terminal position with respect thereto; said cani plate merely slides upon the Hat portion of acid cani lll (best shown in Fig. lvl. then presented, horizontally,y at the top thereof.

In the form of my invententl ehowu in Figs. II, III and lV; said cani halt i3 is part of driving mechanism which may he automatically connected and disconnected with respect to said motor 3, as hereinafter described. lhen operatively connected, Said calais turned in the direction of the arrow marked thereon in Fig. IV, hut is `prevented from turning, when disconnected,

by the frame member .50 which engages the recess 51 in the disk 52 which is rigidly connected with said shaft lil, which shaft is arranged to axially reciprocate in said traine 45. Said shaft carries, rigidlyv connected therewith, the clutch gear which bev eled and arranged to mesh with the driving gear 55 on the counter shaft 56, which is journaled in the bearingr 57 (rigidly connected with said casing il, and has at its opposite end the bevel gear 5S) which is. continually engaged with the bevel gear 60 on the Shaft (il of said motor 3 so that said 'counter shaft 5G is continuously revolved during the operation of said motor. How ever, said cani shaft 43 is intermittently connected with that driving mechanism hy means of the clutch lever G2 `which is fulcrumed at Gil on said frame l5 and has its free end engaged -in the grooved collar tl?) which is rigidly connected with laaid shaft. Said clutch lever is shifted alternately in either direction, to axially,Y recipro 'ate said shaft 43 and thus connect and (lh-:connect said clutch gear 54 with respect to haiti driv-4 ing;r gea r 55, by means including the slide bar 66 which is mounted to reciprocate in said frame l5 and has the tappcl block 67 rigidly connected with it. Said tappet and its Slide bar are operatively connected with Sa id clutch lever by the clutch springr G9 which is attached to said tappet 'block (37 at one end and to Said lever G2 at the other end.` the frame 45 being notched beneath said lever (l2, as indicated in dotted linee iii Fig. ll l, to ermit said lever to Swing to the right wit tout contact between said traine and Said spring 69 which. when free to collapse,

'shifts said slide har 6b' and Said tappet block 67 toward said clutch lever (iz and also Shiite the latter to engage the gear 5l with the gear 55. by axial movemeiit of Said shaft til, loward the right. Suqh movement la eil'ected solely by the tension ot' said spring' llt), he cause it is then effective to more the, tappeti block G7 and lever 62 closer together and, because said lever is held stationair? at the.

axis of ita` ulernin (Sil, Iich tension 1`. translated into movement ot the opposite end oi' aid lever toward the right in Fig. lll; but, in the position of the parte shown in lnig. lll. said fprintf 39 is ati-etched so as to stress said clutch lever 132 toward the left to disconnect said chitch. gear :El from ,said driving gear 55 when said (liek 52 is turned far enough to living; its released portion 51 into ry with said frame projection 50. Said clutch :spring G9 held in that position by the detent- 70 which is fulcrnmed at Tl and provided with the detent spring' 72 so that it snaps into engagement with and normally detains said tappet ti? in the position shown in Fig. lll. AS above stated; said gierig 59 operates to shift the clutch gea-i r 5l in holi directions, solely by tension of said erbringt and in lioth instances. elects a change in the angula r relation ot' the lever 62 with reference to the plane which is common to the axes ol Said shaft lil and said slide bar (it. Vihen said spring; has its left hand end held stationary, by engagement of the tappet block G7 with the detent Tlf?. as shown in Fig. lll said spring tends to increase the angle. between the lett hand edge ol' said lever 32 and said plane, thu, tending to shift the :draft l' and its` agipurtenanees to the left. However, when the left` hand end of said au'ing (3) ie. tree to more.. hy relcaec oi' Said detcnt 7() from Said failliet idool; GT. aa indicated in Fig. Xlll, said :airing tend to decreaecf the angle aforesaid by drawing; :said tappet block ($7 and said lever (l2 closer together and` because said lever (i2 is anchored lo the traine 45. ai its fulcrurn (lil, the tension of said fipring effects movement of :said Shaft tothe right. Said dctcut 70 forms the armature ot' the electromagnet 73 which is capable of releasing;r it from said tappet 37, against the Stresa of said detent spring T2, when energirad by closure of the circuit lcon necting said magnet,- with a `source 'il ot' electric energy and including: the conductora` T5 and 76. The means arranged to-makc and hreak Said circuit. by movement of said box S, include the electric. contact terminal TH carried by said box. and the electric contact terminal 79 carried hyaaid arm '2l ot" the terminal stop lever '20.

ln the drawings; thc initial :stop lever lll i supposed to he :xdjnated in Corresp:unlcuco with the initial convolution H0 oi thc l noovc in aid reet-fnl fl; and thcjterminal stop lever :1U is supplanted to he, adjilstcd in corra-'spondence with the terminal convolution Hl of -aid groove` so that wlafu said st vlua 7 reaches wald tcrniinal convolution Si, the electric circuit ia completed by Contact of the terminal 'IS on said hex 5 with the terminal 7%); eo that fel-.lid dctent 7G is thcn drawn out of engagement with said tappct G7 hy said electroniaejnct 73; thus permit`r ting' .Caid clutch spring (it) to snap said Shaft 43 toward the right in the drawings to engage the clutch gear 5l with said driving gear The continued revolution of said driving gear 55 then turns said cam shaft 43, and the cam 4:2 carriedhthereon, in the direction of the arrow shown in Fig. IV with the effect that` said horn 10, arm (i and sound box are upliftcd from Cooperative relation with said record 9 and then turned, by frictional engagunent of said cam 42 with said cam plate 48, on said shaft 12, until said tone arm (l encounters the padded inner face 15 of the initial stop lever 13 as indicated in Fig. l. Further turning movement of said cam 4'2 merely lowers said horn, arm and box 5 to their initial position in cooperative relation with said record. During that operation. said clutch spring G9 reset to the position shown in Fig. 111 (i. e., with the tappet block (S7 shifted to the left and there engaged b v said detent 70) by means of the crown cam 83, shown in Figs. H and IV, which turns with said shaft 43 andis conveniently mounted upon said clutch gear 54 so to thrust said. slide bei;

(l0 t0 the left, in Figs. Il and IH. Fig. IV shows the parts nearing the completion of the operation of the box feed mechanism; and as above noted` when the recess 51 registers with the projecting frame member 50 (which, until then. holds the clutch gear 5l in engagement with the driving gear 55). said clutch spring (39 snaps said shaft l-l to the left in the drawings. thus disengaging said clutch and locking the feed mechanism against accidental rotation from its inoperative position b v engagement of said disk 52 with said projection 50. lvhereupon, the cooperation of said st'vlus 5 and record 9 is resumed and repeated; onlyY a few seconds inlermissionbeing required for the automatic return of the sound box 5 from its terminal to its initial position as above contemplated. f

Referring to the forni of my invention shown in Figs. V to X inclusive; 85 is a casing inclosing a gramophone including the record turn table 86 arranged to be turned by the motor 87 which is onliv indicated in dotted lines in Fig. Vl but is mounted upon the underside oi' the easing top 88 which is detachably rigidly secured on said casing The sound box 89. which is carried by the tubular tone arm 90. includes a vilnatoriT diaphragm and carries the stylus 91. indicated in Fig. VI, arranged to traverse a groove in a record 93. on sa id turn table 86, and automatically shift said box toward the axis of said table. The amplifying horn 94 is rigidly connected with said casing S5 but is pivotally connected with saidy tone arm 90 at 95. f

The collar 96. which is detachably secured upon said horn 94 by the setscrevv 97, carries the adjustable initial stop lever 98,

which is arranged to be manually secured in adjusted position by the set screw 99 shown in Figs. V and Vll. Said lever 98 rests upon the flange 100 ot' said collar 9G, which is convenienti).v graduated as indicated at 10:2 in Fig. YH so as to be traversed by the index lug 103 on said lever 98; whereby the position of said lever may be accurately determined so as to limit the initial position of said box 89 in cooperation with ,said record 93 at the outer limit of its movement with respect to the axis of said table As said sound box S9 is car'ied across said record 93 in cooperative relation therewith and toward the axis ot' said table 8G, said tone arnrf() is swung in the direction ot' the arrow indicated in Fig. V: 'its terminal position being indicated by the dash lines in that ligure corresponding with the terminal position of said sound box 89 with reference to said record 93, and the adjust able terminal stop lever 106 is arranged to variably limit the terminal position of said box 89 by adjustment of said lever 106 circurnferentially with respect to its fulcrum upon theY screw 19T which has the milled head 1.08 whereby it ma).Y be manually turned to clamp said lever 106 in adjusted position. As hereinafter described, the free end of said lever 106 is an electric contact terminal of a circuit. controlling the operation of the sound box feed mechanism shown in Figs. V to inclusive. i i

.ks indicated in Fig. Vl; said motor .S7 has theA shaft 110 provided with the bevel gear 11.1 continually engaging the bevel gear 112` on the counter shaft 113 which carries the driving gear 114. so that the lat- `ter is continuously revolved during the opevition of said grainophone. The automatic feed mechanism for said sound box 89 includes the clutch gear 115 is alten nately operativel)1 connected and disconnected with respect to said driving gear 114, as follows:

As best shown in Figs. Vil and VIII; said clutch gear 115 is carried b v the sleeve 11i'1 which is journaled, for rotation and axial reciprocation. upon the stationary stud sha'l't 11.8 (which rigidly connected with said collar 9(5) and is shifted to and from engagement with said driving gear 114 b v the clutch lever 120 which fnl crumed at 121 uponthe frame plate. 12,2. Said clutch lever 120. has its free end ex tending between said clutch gear 115 and the flange 123 on said sleeve 117. and is provided with the clutch spring 125 which is constructed and arranged to snap said lever and said clutch gear 115 both to .der longitudinal tension and transverse flexion. between said levers 120 and 126.

Said spring is set to snap said lever 120` tio to im inoperative position shown in Fi fill land to retain it in that position` until raleabed), by the lever 121i which is fulrrnnied on the screw 12T rigidly connected with said plate Said lever 126 has its tappet arm 129 engaged by the detent lever 1110 (best ehown in Fig. VIII) which is fivoted on the screw 131 which is in rigid irlaiion with said plate 122. .Said detent 130 is preased into the position shown in iiig. .'IH by the epi-ing 13:2 which is also rigid@ connected, at one end, with said plate Said detent 1.30 may be. ninnuellj: released by movement in the directif. :it the arrow marked on the right hand eno .hermit in Fig. VIII; Such movement heim; En onnosition to the pressure of said ng 11152. llmvever. l provide electrically Controlled ineana for effecting such release and thus; initiating the operation of the auto matie hoi: feed mechanism, inohuling the :slwtroniagnet 11i-1 haring the armature 135y piroed at 136. in eonneetion with Said baSe plate 1:32, and having its free end resting upon the right hand end of said detent lever W as 'iliown in V11 and V111. lt is in be luide-retinal that when Said electro-magnet 134 in energized, Said armature 135 is .arctaneonsly drawn down to release said ring lever 126 and permit the Spring 125` to rollaiiae andnhift saidelutchlever 120 in the direction ofthe arrow marked thereon in Fig. V11 (by the longitudinal Collapse Iind horizontal exnre ot' said spring 125, which iii-nds to straighten itself; supplemented bv the eoaeequent momentum of said lever 12(1) in engage Said clutch gear 1.15 with said driving gear 111. Said eleetroinagnet ia 'nini` energized by closure of the electric eirfait inrlnding the conductors 138 and 139, indieated in Fig. V, which are respectively vnnnveted with said terminal Stop lever 1,06 :ind with the metallie parte in electrical eonnerlion with said tone arm 9U. As `ehown in Fig. Y Said conductor 139 includes` the nii of said electro-magnet 134 and has iin: end elamped upon the `basse plate 122 by the liraeliet carrying the fuleruni of the 130. Said base plate is in eleetrn i irruit with the tone arm 90 hy the inf-faille parte `shown engaging each other in Figs. and Tl. Aa the sound box 89 normally ironia-illy insulated 'from said tone arm 90 3' the mit rubber flange 111 which i5 part or' the ordinary \'irtor machine Structure; ,i gorie-r in r-lertrieally eonnect Said box 89 with aid tone arm. and than with said conlnror 1i .1, h v means ot' the conductor 1-12 indiraied in dotted lineal in Fig. V, bridging lal'ing flange 111; .@:o that said ciri nii and 139 including said electromagni lill and the generator 113, is cloned when smid .wand box 8f) touches the termii d 'iwi nl' 4aid adjustable terminal lever :Clit Ef. ii; to he understood that said lever is So adjusted that said on'euit 'is thu@ closed when Said stylus 91 reaches the terminal vonvolntion 115 on said record 93.

AS shown in Fig. X, said flange 123 on said Clutch sleeve 11T has the recess 147 to -reeei-ve the Stud 148 whieh is rigidly 00nneeied with said base plate` 122; so that when said clutch gear 115 is in the inoperative position shown in Fig. VII it is thus prevented from` accidentally turning. However, when said elutC-h gear is thrust into its operative position, as above de- Scribe-.d` said flange 1:23 is shifted. with the elnteh sleeve 117, to' the right of its position shown in Fig. VU, far enough to rlear said stud 148, and, as said sleeve is ii'nmediately turned by the engagement of said gears 114 and 115, Said stnd 1,18 prevents the accidental disengagement of said gears until thv ear 115 has made a complete revolution, again presienting its` recess 11i' in registry with said @tud 148. During that revolution of the Sleeve 117 the spring 12T is reset to the position Shown in Fig. VII by the, crown earn 150, a'liirh is also rigidly ronneeted with said Sleeve 117. and then encounters the Stud 151 whieh is rigidly ror-v ni-eted with Said Spring lever 19t?. lt is to be understood that during Said revolution said lever 12F is gradually pressed in the opposite direction to that indirated by the arrow thereon in Fig. V11. until its end 12.() again anaps into engagement with the detent lever 130, in the position shown in Figs. VII and VIH. Therefore. when said single revolution of the Sleeve 117 is vomi pleted, said spring 125 has been so set. in extended position, that when said recefis 117 in the, flange 123 is presented in registry with the Stud 148, as shown in Fig. X. said sleeve 11T inetantlyT snapped toward the left in Fig. VH to disengage the clutch gear 115 from the driving` gear 114.

Daring that single revolution of the. `aleeve 117 of the box feed n'iechanism, said box 89 is raised from the record 93 rind. with its tone arm 90, returned to its initial pont-ion, in'the direction opposite to the arrow shown in. Fig. V, h v means of the `eingle earn 152, best Shown in Fig. IX` whieh registers with the arenal arrn 153 on the lever 154, shown in Figs. V and V1, whieh is fulcrumed on the stud 155 rigidly eonneeted with said tone arm 90. W'hen said cam 152 reaehes its normal position shown in Fig. 1X, said lever 139 has been returned to its normal position shown in Figs. V and VI, by the weight of the sound box 89 which gravitates to operative position with reepeet to the sound record 89 as. the arenal end 1321 of Said lever 139 is iowered `h v said rain 152: the automatic feedingmovement deserihed having been efieet- `ed in a few seconds hy the single revolntion of said sleeve 117.

In both of the embodiments of my invention above described, the closure of the electric circuit which initiates the operation of the box feed mechanism is eiectecl by contact of two electric terminals, one of which is carried bythe sound box and the other of whichA is stationary except` when nian-` nelly adjusted as described. However, my invention may be embodied in a sound producing machine which does not require any manual adjustment of the electric terminals at which closure of the circuit is eli'ected. For instance. in the form of my invention shown in Figs. XI and XII, which includes a graphoplione sound box 156, (which it is to be understood is associated With the other essential elements of a graphophone of the general character shown in Figs. I to IV inclusiveg)V the closure of the electric circuit is effected by contact of the terminals 157 and 158, both of which are carried by, or in connection with. said sound box 156. As indicated iii Fig. XII. said terminal 15T is a wire loop, pendcnt from said sound box 15G but having the right hand portion thereot' insulated as indicated by the black portion 159 thereof. Saidterniinal 158, which extends freely through said loop terminal 15T. is carried by the st vlus lever 160 which is mechanically connected with said sound box 156, as indicated in Fig. XI, but is electrically insulated therefrom by the insulation 161. rTherefore. it is to be understood that the electric conductors 16:2 and 163, shown in Fig. Xl. are opposite.

sides of a circuit including a source of elec-` tric energy and an electroniagnct. such as above described. constructed and arranged to initiate the 4operation ot an automaticfeed mechanism for sound boxcsf lVlien in operative relation with tliesound record. said sound box 156 is moved in the direction otV the arrow marked thereon in Fig. XII and, during such movement, said terminal 158 `is free from the terminal 157 `and prevent operation of the. automatic feed mechanism for thelsound box; it may be observed that my invention includes certain features of mechanical construction and arrangement to which the specific construction and a1'- `rangement of the electric controlling means is not essential.

Therefore, I donot desire to linut myself to the precise details of construction and ai" rangement of my invention herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features thereof as defined in the appended claims.

I claim:
