TALKING-MACHINE.

Specification of Letters Patent.

1 Application filed December 13, 1919. Serial No. 344,622.

To all whom it may concern Be it known that I, MAX KRAUSS, a subject of the Kin of Bavaria, having residedv in the United tates for two years last past and having declared .my intentions of becoming a citizen thereof, residing in the city and county of Philadelphia, State'of Pennsylvania, have invented a new and useful Talkin -Machine, of which the following is a speci cation. 1 My invention relates to the general class of talking or sound-reproducing machines which play records in the form oflfiat disks,

both single and double faced, and it ems.

bodies certain improvements upon a talking machine invented by and patented to me under date of September 26th, 1916,- as No.

1,199,192, and further relates to another invention of mine in talking machines patented to me under date of January 14th, 1919, as No. 1,291,027, and's'till further relates to another talking machine invented by me and patented tome under date of ferred to, namely No. 1,291,027, the features of invention have special relation to means "ticularly to special means for moving and for applying and removing the records, while in the last of my patents, No. 1,291,556, the invention relates more parcontrolling the tone arm and its soundbox with relation to any one of the plurality of records which the machine is adapted to play.

My present invention while embracing the salient features of my former invention referred to, has special relation, first, to a novel means of controlling and operatlng the tone arm and sound box relatively to any selected record, and, second, to a means for independently operating a selected record without at the same time operating anyof the other records of the plurality of which the selected record constitutes but one. 4

This last feature is one which my present invention especially relates to, because it is my princlpal. object to simplify the construction and utilize less motive power by making it possible to revolve but one record at a time.

Patented June 1, 1920.

With the foregoing and other objects in view, my present invention comprehends not only such a means as the foregoing of operating one record at a time, but also special constructions of the devices by which not only such operatlng of but one record is effected, but also such control of the tone armand soundbox is afi'ordedas makes the operationboth accurate and eflicient.

Special devices embraced in the construction of both the connective mechanism between the motor or source of power and of the controlling devices of the tone arm and sound box, are included in my invention and hereinafter described, a typical'embodiment of a good construction being disclosed in the accompanying drawings, which illustrate an embodiment adding to the efficiency of certain of the features which the inventions of myformer patents include.

For aclearer understanding and differentiation of the features of importance which my present invention embodies, reference is to' be made to my prior patents, the present application representing only so much of a talki standing of the novelfeatures.

My present machine, like those,previously patented to me, is adapted for'use with any form of soundbox the stylus of which can operate either upon the up-and-down tone groove of the type of the Edson, or the inand out groove of the type of the 'Victor, machines, only one sound box beng machine as is necessary to an undering necessary to enable the operator to-at will select and play-any one of any desired number of records which have been set up in my machine.

The machine, moreover, is capable of being operated by any preferred type of motor, whether mechanical or electrical.

Referring to the drawings 1 designates a cabinet or casing of any preferred character, material and dimensions, which bymeans of a horizontal partition 2 is divided into two hollow interior compartments, the upperof which I designate 3'and the lower 4.

5 designates the front face of the casing through slots in which the operating handle .being applied to the body portion of said tone arm or that portion which extends between the outer end to which the soundbox I0 is applied and the inner end where a jointed or swiveled connection hereinafter described is made between the tone arm and an elbow member 13 extending above and being a part of a horn carrier 14, from the lower end of which a horn 15, see Fig. 8, extends. This elbow member is connected with and supported and carried by a traveling, carrying plate 16 which travels upon the rods 19 extending longitudinally of the partition in the casing and in parallelism with the axis of the hubs which carry the records.

17 designates a slot in the partition 2 through which the horn carrier extends reference to it, embodies elemental features included in my'patents referred to.

The'tom arm operating mechanism.

Inasmuch as in the operation of my machine it is necessary to impart both an upand-down or a lifting and dropping movement to'the tone arm to raise the soundbox clear of all the records and to'move it down into place between anytwo of the plurality of records so that it's stylus will play upon one of them, I have found it convenient in downwardly into the lower compartment 4 of the casing; So far as already described, my machine, as .will be "best understood by two parts by a compound joint of the following construction Referring to Flg. 5 ,-21 designates a crossbar secured by pivot pins 22 to the free outer end of the elbow member, as shown in '4,e\;and pivotally connecting the inner open end ofthe tonearm with a right-angular cross bar 23, preferably integral with the crossbar 21 and at its outer ends carrying pivots 24 which passthrough pivot apertures 25 in the tone arm. This construction,

which is best illustrated in Figs. 4 and 5,

. t permits, as is obvious, of an up-a nd down movement of the tone arm upon the cross bar 21 as an axis, and a side-for-side or swinging movement of said tone arm upon the crossbar 23 as an axis. e

Inasmuch as sound could escape through this compound joint unless it were prevented, I encompass both the inner end ofthe tone arm and the outer end of the elbow member of the horn carrier with an envelop 26 of cylindric form and composed of sheep skin or other preferred pliable and soundproof material, which I rigidly secure to the tone arm conveniently by a collar 27 and by a clamping nut28 internally threaded to embrace the externally threaded outer --end of the elbow member so as to fasten the en op, as will be understood by reference to Fig 4. v I v I The handle mechanism. 29 designates what I term the operating handle, the same being a lever having bifurcated ends 30 which ennompass the elbow member 13 and are pivoted to it-at 31, see

5 fectthe sidefor-side swing of the Fig. 6. The extremities of' the bifurcated ends 30 of the operating handle are connected by a cross link 32 from which depends a connecting link 33,-for a purpose hereinafter explained. A spring 34 connects an outer end of the operating handle with the traveling carrying plate 16 so as to tend normally to maintain the operating handle in its upper position, as shown in 's will be observed from Fig.- 6, the outwardly extending'handle end of the operating handle 29-,'or that which as shown in .-Fig'. ..8 ;extends through slots'in the front facei5 -.of-'-the casing, is a bent bar, the side plates ofwhich, to which the numeral 29 is also applied, are. spaced apart a snfiicient distance to leave between them a longitudinal'slot 35 within which is entered thefulcrum end 36 of what I term the swing lever 37, the function of which lever, througluits connections now to be explained, is to 'eftone arm, whereas the movement of the operating handle through connections later o'n'..explained effects the up-and-down movement of said tone arm. v

This swing lever ispivoted at 38 to the side plates 29 of the operating handle, as

' seen in Fig. 3, so that t e lever upon these pivots as a fulcrum, can be depressed by .toe in turn makes contact with the ball shaped bottom end of a lifting bar 43 pivoted at 44 to the outer end of a rocking frame .45, see Figs. 3 and 4, which is bent to encompass the elbow member 13 of the horn carrier and locked by the squared end 46 of pm; of the pivot pins 22 of the cross bar 21 by a clamping screw 47, see Fig. 4, which passes througha squared socket 48 on the inner end of a carrying plate 49 to the outer end of which is pivotally jointed upon a vertical rod 50 the inner end of a swing bar 51, the outer end of which is fastened at 52 to the tone arm.

Apart from any other movement, it will be understood that wh'enthe swing lever 37 is depressed and its lifting toe held in contact with the enlarged lower end of the lifting bar 43, and that when, the swing lever being held in such position, the operating handle ,29 is depressed,the tone arm will be elevatedthrough the rocking frame 45, the carrying plate 49 and the swing bar 51. g It will be further understood that when the operating handle and swing lever are released, the tone arm will be free to be again raised into operative starting position. 4 v

The balancing of the tone arm in given positions I effect by. the employment of Q; counterbalance weight 53, preferably stayed v for vertical movement by being bored as at I under bend'59, through which tlgapivot 57 passes, and is bent away from he handle 'to form a contact lug 60 held normally against the side of the operating handle by as ring61.

xtending inwardly through a slot 62 in the side of" the handle is an angular cam pin 63 againstwhich the shoulder 41 of the of sai swing lever, to bear, and. to be forced outward so as to force the contact lug 60 away from the operating handle.

When the swing lever 37 is in its elevated swin lever 37 is adapted," the deflection position, the swinging side plate 68 and its outwardly extending contact lug 6O occupy the positions shown in full lines in Fig. 6,

.and when the swinging lever is dep ssed occupythe position? indicated in dotted lines in said figure The object of forcing out the contact lug 60 in the manner described, is to cause it by bearing against the inner end plate 65 of a connecting lever 64 to turn said lever upon a vertical pivot 66 passing through a lug 67 fast upon or connected with the elbow' member 13, see Figs. 3 and 15. The outer end of this connecting lever is formed with a slot 68 through which passes what I call a twisting pin 69 formed on the lower end of a vertical rod 50 by which the swing bar- 51 is connected with the carrying plate 49,see Fig. 3.

The twisting pin 69 is locked fast to the lower end of this vertical rod 50, and to the upper end of the rod is locked the inner end of the swing bar 51, so as to fasten said bar upon the carrying plate 49 and at the same time permit of the movement of said bar with the twisting pin 69 when the latter is turned or twisted by the throw of the connecting lever 64 as already explained.

The return of the twisting pin 69 and the swing bar 51 is effected by a spring 7 O coiled about the vertical rod 50 to one end of which said spring is connected while its other end is fastened to the carrying plate 49.

The inner end of the ,swing bar 51 is formed with a notched shoulder 71, see Fig. 4, which bears against a stop pin 7 2 on the upper face of the carrying plate 49, the office of which is to prevent the uncontrolled throw of the tone arm, and in consequence of the stylus, against a'record.

The'swing lever 37, controls the side-forside or lateral movement of the tone arm in the manner already described, and the operative effect of the coiled spring 70 acting through the twisting pin 69 upon the connecting lever 64, is to balance or oppose such movement, by a reverse action upon the swing'lever 37 through the swinging side plate 58, the contact lug 60 and said connecting lever 64.

The slot and notch control.

Through the front face 5 of the casing 1 extends, as stated, a longitudinal slot- 73 throu' h which extends as best shown in Fig. 8, both the outer end of; the operating handle and the thumb knob end of the swing lever.

. stepped at its side, 1

course, other notches for records of and the strips 80, see

diameter than ten inch or greater diameter than twelve inch may be formed in the vertical slots. 1

Intervening' each vertical notch and formed as a part of the front face and in a sense together forming the upper line or boundaryof the longitudinal slot 73, are a series of what I term stop blocks 77 against which in its longitudinal movement the operating handle may be brought to bear so as to" hold it down for thestopping of the rotation of the records.

These vertical notched slots are disclosed in my Patent No. 1,291,556, as operative in connection with the selector'arm and lever latch of themachine of that patent and'are not involved with my present invention except in so far as they serve in connection with the stoppage of the record motive mechanism.

The record motive mechanism. 4 As already explained, my present invention provides means for operating each of the records independently of every other record of the series or groups. My object in this particular is to relieve the motor of'the duty of rotating all of the records simultaneousl which necessarily adds to the expense 0 operating the talking machine because of the additional power required. To the foregoing end, each record is directly connected. with an independent motive mechanism of the following preferred character 78 designates shaft carrying bars assembled and supported by and between a longitudinally extending connecting rod 79 Figs. 1, 8, 12 and 13, between recordslots 7 in the record-carrying plate 6.

These shaft carrying bars 78, one of" which is used in connection with each pair of record-clamping devices hereinafter described, are each provided with an upper housing 81', see Fig. 9, for. the driven gearing of the"recordj-carrying plates 82, and with a lower housing 83, see "Fig. 10, for

the driving gearing connective of what I term the recorddriving shafts 84 with the transmission mechanism hereinafter described. v

Asa reference to Figs. 9, 10, and 13 Wlll bestillustrate, within the upper housing 81" of each shaft-carrying bar 78 is housed in suitable bearings 85 a separate record-carrying shaft 86, which carries a driven bevel spur wheel 87 engaging with a driving bevel pinion 88 on the upper end of the driving shaft 84.

Upon this shaft series is a duplicate of every other I 'will describe only one,is fastened the plate 82, which is the fixed member of the recordclamping device, and is of a diameter pref- 86,-and as each of the erably not exceeding that of the smallest records to be played and conveniently in the form of an apertured. disk, which, as is obvious, rotates with the shaft 86 under the actuation of the bevel gearing 8 7, 88.

This record shaft 86, see Fig. 9, projects beyond its housing 81 in both directions, so that upon the left-hand it forms a stub end directly designated by the number 86, and upon the other or right-hand end is formed with a circular groove =89, into which is adapted toenter the angularly faced, semicircular aw 90 of a spring-controlled thumb latch 91, pivotally connected at 92 to the hub 93, see Fig. 9, of a tubular outwardly extending collar 94, which is adapted to slipover the grooved ri ht-hand end of the shaft 86 and be clampe thereto by the action of the jaw 90 when entered within the oove 89. 2 r

This hub 93 is formed or connected with a plurality of radially extending clamping spring plates 95, see Fig. 11, which in the movement of the parts are adapted to press against the face of the record opposite to that which lies against the, clamping plate 82, Fto retain the record fixedly for rotation upon and with theshaft 86.

The movement of the latch 91 referably to its pivot 92 is controlled by the spring 96 and the stop 97, as shown in Fig. 11.

It is evident that by manually moving the latch 91 endwise to theright in Fig. 9, the hub 93, collar 94, and spring plates 95, which together constitute the moving member of the record-clamping mechanism, can be moved to the right, the collar 94 slipping over the left-hand end of the right-hand adjoining shaft 86' t0 the position shown in dotted lines in Fig. 9, so as to afford a clearance for the introduction of the record upon the left-hand adjoining .shaft 86, and its fastening against the clamping plate 82,-

when thehub, collar and spring plates are moved to the left, as shown in full lines in Fig. 9, and so as to permit of the clamping of the jaw 90 into the groove 89 on said shaft 86.

The rotation-\of the selected shaft 86 to rotate its record, is induced through the bevel gearing 87, 88, by the rotation of the driving shaft- 84, which extends downwardly through a bearing 98 in the lower housing 83 and is rotated through the driven b vel pinion 99, which is in mesh with the riving bevel spur wheel 100 fixed upon a stub shaft 101 suitably mounted in bearings 102, see Fig. 10,:in the lower housing 83.

Upon the stub shaft 101 is mounted a driven spur wheel 103, which, when rotated, will obviously impart rotation through the stub shaft 101 and the bevel gearing 100 and 99 to the selected record-driving shaft 84.

This entire last named assemblage of driving elements is best illustrated in Fig. ii 10, an ,inasmuch as there is, as stated, connected with each shaft-carrying bar 78,-ofand for each record a similar organization,

it will be understood that means for rotating the driven spur wheel 103 in each 8f the lower housings 83 will occasion the rotation of the selected record intended to be operated, through the rotation of said spur wheel 103 and ail'of its connected record driving mechanism, and will not occasion the rotation'of any other record of the as sembled group of records.

The transmission mechanism. Referring now more particularly to Figs. Y 8, 12, 13 and 14,-104 designates a traveling frame for supporting and carrying a novel and special gearing which,-at the will of the operative, transmits power from the motor to any selected driven spur wheel, 103,, to

drive any selected record.

' 1 24 upon the'upturned bracket ends 1108 of v s a carrying bedplate 109 fixedly secured, 106 was convenience .of manufacture .may dictate,

within said lower compartment of the easing and preferably in vertical planar aline ment below the axis of the record shafts 86.

The traveling frame 104,.which; as stated, rests upon the rails 105, 106, bears against said rails by frame blocks 110, see Fig. 13,- depending from its base.

111 designates side frames parallelly and vertically disposed with relation to the base of the frame 104 and serving as supports for suitable bearings of a front stud shaft 112, upon which are fixedlymounted both a spur wheel 113,'see Figs. 12 and 13, and

a worm wheel 114 engaged with a worm 115 115 of a wormshaft'116, upon which shaft is mounted a typical governor 117 hereinafter more particularly referred to.

The spur wheel 113 engages with a spur pinion 118, Figf13, feathered upon a driving shaft 119 which extends longitudinally of the casing between the end standards 107 I of the frame 104, in bearings 120 in which standards said shaft is mounted; and -carries, feathered also upon it, a driving spur wheel 121,.preferably in hubbed connection 7 I with the spur pinion 118.

Assuming rotation impartedto the driving shaft 119, it is obvious that through. the

spur pinion :118,'rotatio'n will be imparted n to the spur wheel 113, see Fig. 12, and that the speed of rotation of said spur wheel will be governed by. the dimensions of the teeth of the spur wheel 103 and those of the pinion 99, and the adjunctive gears.

Assuming, further, the desired rotation imparted to the driving shaft 119 and the driving spur Wheel 121 feathered upon said *sh'aft and rotating with it,if,- then, as is evident, said drivingspur wheel 121 be engaged with any one of the driven spur wheels 1.03 on the stub shaft 101 in a lower housing of a record driving shaft 84, that V shaft and in consequence its record will be rotated and driven.

The operation of the transmission mechm Inasmuch as it is desired through the preferred transmitting mechanism under description, to be able to engage and drive any selected one of the driven spur wheels 103, it is obvious that it will be necessary to be able not only to move the traveling frame 104 which carries the above described transmitting mechanism endwise upon its rails,

but also beable to throw or tilt the drivr 0f the side frames 111 of the traveling frame 104. Obviously, when by means of the operating handle 29, the horn carrier 14 is moved longitudinally of the casing through the fixed connection of this frame-moving bar 122 extending from it to-the traveling frame 104, the last-mentioned frame with its contained adjuncts will be moved-longitudinally of the casing upon .the rails 105, 106,. so as tobring the drivingspur wheel 121 into line in front of any one of the driven spur wheels 103.

In order to insurea contact between the driving. spur wheel 121 and any one of the driven spur wheels 103 without risk to the teeth of said wheels, I find it advisableto be able to tilt the entire traveling frame, together, of course, with the rails 11 on which it travels and the end standards 10: to which said rails are connected, with reference to the pivots 124on the upturned bracket ends 108 of the carrying bed plate 109, and this I conveniently accomplish by the following means r 126 designates what term a tilting arm, ,which is almost parallel with the framemoving bar 122, as best seen in Fig. 8, and

whichv at its lower end is connected by a 140 on the driving shaft 119.

boxing 123, see Fig. 13, mounted on the drivingshaft 119 and at its upper end is connected by. a pivot 127 to the lower arm of a bell crank lever 128 pivoted at 129 to a bracket 130 extending from'the horn carrier14,-the bell crank lever 128 being at its upper end slotted at 131 to a connection at the lower end of a depending link 33', the upper end of which is connected at 32 to the inner end of the operating handle 29, 'see Figs. 3 and'6.

Obviously, the depressionof the operating handle 29 will, through the link 33, occasion the lifting or upward pulling through the bell crank lever 128 of the tilting arm .126, and, consequently, through its connection by the boxing 123 with the driving shaft 119, the tilt of the traveling frame and all of its connective adjuncts with relation to the pivots 124 between the end standards 107, and the upturned bracket ends 108.

The connective mechanism from the motor.-

In order toactuate the driving shaft 119 to effect through the connections already described in the traveling frame 104 the spur' a motor shaft, suitably housed in standards 133 connected with, or preferably components of, the bed plate 109, see Figs. 12 and 14, which through a belt or chain connection 134, see Fig. 8, from a sprocket or pulley a 135, see Fig. 13, connects directly with a mo tor or prime mover of any character, not shown, but serving to impart rotation to said motor shaft 132.

Upon the motor shaft is mounted a driving spur wheel 136, which is in engagement with the driven spur wheel 137 on a stud shaft 138, upon which stud shaft is also mounted another driving spur wheel 139 in engagement with anotherdriven spur wheel Obviously, through this" connective gearing which is typical merely of a good form of gearing, the motion derived from the motor will be transmitted through the motor shaft. 132 to the driving shaft 119, to the end of operating the transmission mecha:

"nism in the traveling frame.

The stopping mechanism. When for the time being it is desired to stop the rotation of the driving shaft 119 in order to permit of the longitudinal move-- ment of the traveling frame 104 and its -aldjuncts from 'one record driving mechanism to' 'ahojther, I find it convenient to utilize in connection with the governor 117 the following contrivance illustrated in Figs. 8, 13 and 16,- namely I The disk head 141 of the governor, which is mounted to rotate with the worm shaft 116, see Fig. 13, isalso adapted to have an end-forend or transverse movement upon said wormshaft, and it is obvious that if frictional pressure be exerted against the face of said disk head it will cause a stoppage of its rotation and consequently a stoppage of the operation of the worm and the train of gearing which imparts the desired rotation to any one of the driven spur Wheels 103.

This stoppage should, of course, be'effected at the time when the traveling frame-104 is tilted soas tounmesh or disconnect the teeth of a given driven spur Wheel 103 and those of the driving spur wheel 121.

As already explained, this tilting is effected through the operating handle and its connections pulling upwardly on the tilting arm 126, and the effect of the tilting is to cause the front edge of one of the side frames 111 to bear against the upturned end 142 of what I term a stop-crank-lever 143,. which is pivoted at 144 conveniently to a lug.

145 connected with the frame moving bar 122, as shown in Fig. '16.

The end of the. crank'lever opposite to its upturned end 142 is formed or provided with a friction stop 146 of leather or kindred substance, which, in the assemblage of the parts, normally stands at a distance from the disk 'head 141 of the governor, but in the tilting of the traveling frame is caused" to contact with said disk head so as to stop its rotary movement, which, as already explained, isdue to the transmission gearing operated from the motor through thecon neotive gearing upon its worm. When, then, the entire transmission gearing is thus stopped it is obvious that it will be easy to shift the traveling frame and its adjuncts in either direction longitudinally of the rails 105 and 106-and the driving shaft 119, and ,then' .by a further release movement. upon the operating handle, to make first the desired shift and then the desiredre-tilting of the traveling frame 104 tomake the desired new contact between the teeth of the driving spur wheel 121 and those of the driven spur wheel 103 of the driving mechanism of the selected record.

'Having now described aconstruction con-" veniently embodying my invention, the op-, eration of the elements-as,lsuccessively ,de-

scribed, ,will have been understood, and it will, therefore, be unnecessary to repeat how the entire organization may be operated to play any particular reccrd.

In other words, it is sufiicient to"add that when the selected plurality of records,de-.

ords are double faced, in order to pending of course upon the dimensions of the machine as an entirety, has been put in place and the motor started to occasion through the connective mechanism the rotation of the driving shaft and through it and the transmission mechanism the operation of the; record motive mechanism of a selected record,the operator having through the operating handle 29, the swinging lever 37 and their adjuncts, placed the transmittingmechanism in position to operate the desired record motive-mechanism and then looked" the operating handle in proper position in the .slot in the front of the casing,the rotation of the selected record will occasion its playing until the record has been played and stopped itself, or at the will of'the operative, the stopping devices have been thrown into action, or, if

.desired, the motor of the machine by any itation to be played, while all of the other records of the group are standing still.

This is of course also true when the assemblage of records has been turned by the half turn of the circular record-c'arrying plate 6, as may be done when the recone face and then the other. Thenovel and useful construction, which I have illustrated and explained is well 'adapted to carry out the'objects of my invention, but whlle'the embodiment referred to is both desirable, inexpensive and satisfactory, it isto be understood that it is suswithout departing from thespirit or scope of the invention or sacrificing any, of its advantages. Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1.In a sound-reproducing. machine of the character described,- a group of independently operative revoluble records dis.- posed in adjacent parallel planes upon a common axis of rotation,--a motive mechanism for operating any one of the" records of the group independently of all of the I other records, and a manual lever control extending externally of the casing for operating said motive mechanism. 2.
