Specification of Letters Patent. I

Patented Nov. 7, 1 916.

Application filed september 25, 1907, Serial No. 394,584. Renewed Mai-ch30, 1916. Serial No. 87,875.

To all whom itmay concern:

Be it known that I, EDWIN WALKER, a citizen of the United States, residing in Erie, in the county of Erie and State of Pennsylvania, have invented a certain new and useful Phonograph, of which the following is a specification.

This invention is a phonograph the carrier for. the record of which is simultaneously rotated and given a traveling movement with respect to a relatively stationary reproducer.

According to one embodiment of this invention, the record-carrier is mounted on a traveling carriage, and with said carriage and 1 the record-carrier are combined devices forsimultaneously rotating the recordcarrier. and for feeding the carriage at a proper rate of speed, the movement of'the carri ge being a slow one as compared with the speed of the record carrier.

The carriage, its operating devices, and the driving means for the record carrier are simple and durable in construction, and operate with very little friction, wear and perceptible noise.

A broadly new feature of the'instrument consists of means for simultaneously adjusting the reproducer and controlling the motor which operates the record-carrier, whereby records may be removed and replaced without scratching or multilating them by the stylus of the reproducer, the latter being 1 supported firmly in position and out of the Way during such interchange of the records.

The reproducer which it is preferred to emplo is of the character disclosed in my prior atents No. 805,544 and No. 805,600,

- as well as in a copending application Serial -No 394,586, filed on even date herewith.

For the purpose of conveniently 'carrylng the reproducer and the entire machine, it' is preferred to provide a portable case in ,which the motor and working parts of the machine are installed'permanently, said case being provided with compartments for the reception of the reproducer as well as of a number of records, etc. A 7

As disclosed in the aforesaid Patents and I application, the reproducer is provided with a plurality of styli, and it is adjustable lengthwise for. bringing either stylus into engagement with a record. 9

A According to the present invention, the reproducer is,. preferably, equipped with means for supporting. it firml in either of several adjusted positions. aid support- 1ng means restrains the reproducer from sldewise movement in a horizontal plane,

but permits free movement in a vertical plane. One element of theaforesaid supporting means is foldableinto compact relationwith the reproducer when the latter is dismounted and packed in-the aforesaid portable case, whereby the reproducer may be easily removed or replaced, as desired.

In the accompanying drawings, I have illustrated one practical embodiment of the invention, but the construction shown thereinis toflbe understood as illustrative only,

1and not as defining the limits of the invenion.

Figure 1 is a side elevation showing the portable case in an open position and the parts of the phonograph adjusted in position ready for use, the combined horn and reproducer being supported in a raised position with respect to the record carrier or mandrel, in order that a cylindrical record may be placed readily'on said carrier or .80 -mandrel. Fig. 2 is a vertlcal cross section through the ,portable casing, showing certam parts of the'machine in longitudinal sectlon and side elevation, the combined horn and reproducer being-illustrated in end elevation. Fig. 3 is a plan view of the port able casin and the phonograph, the horn and repro ucer being removed. Fig. 4 is a vertical section on an. enlarged. scale and in the plane indicated by the dotted line 44 of Fig. 1 looking in the direction of the arrow, the reproducer and horn being omitted. Fig. 5 is a vertical section taken on the line 5-5 of Fig. 4 looking in the direction of the arrow. Fig. 6 is a detailcross section through a part of the carriage, showing the feed shaft and the feed-lever ortraveler which cooperates with said shaft, the plane of the section being indicated by the dotted line 6-6 of Fig. 2. Figs. 7 and 8 are views in side and end elevation illustrating another embodiment of the invention. K For convenience in transporting the machine and. the records, I have shown a porpartments, B, B, B The compartment, B, is adapted to receive the Combined horn and reproducer, C, when the latter is dismounted from operative relation to a record. The

' 5 compartments, B,-B provide forthe storage of a number of records, and between said compartments is a motor casing, D, which contains the operating parts of the motor whereby the record is rotated on its axis and moved endwise with re'spect to thecombined horn and reproducer. v I Y Within'the compartment, B is mounted 01; secured a baselplate, E, the same extending crosswise of the portable'casing, A, at one end thereof. This base plate is provided with longitudinal parallel rods, 6, e, which form a track for a' slidable carriage, Fl

' Said carriage is shou .1 as consisting of the members, 7", 7, each of which is cast in a single piece of metal, substantially in the form-represented in Fig. 6. The members of the carriage are joined rigidly together by appropriate longitudinal tie-rods, f, and said members are provided with the arched or curved upper end, P, each being formed with a depending perforated lug, 7, see Fig. 6. At the respective sides of the carriage are grooved rollers or'wheels, e, 6 the rollers, e, beingadapted to ride upon the rods,

1 e,of the track, while: the rollers, 0 ride 'against the underside of said rods, whereby the carriageis limited to sliding movement \on the track, and the'vibration of said car 'riage is minimized by the engagement of the rollers with said track. The carriage supports a record carrier, G, herein shown as a tapering mandrel for the reception of cylindrical records. Said mandrel is provided with a shaft, G, which extends lengthwise of the carriage and is journaled in the apertured lugs, F, of the members, 7, composing said carriage. The shaft, G, is mounted I for rotation freely within its bearings of the carriage and it is moved endwise with said carriage, whereby the mandrel, G, is adapted for both rotary and 'endwise movement.' The mandrel, G, is mounted on a shaft, G, and this shaft is provided with a longitudinal groove or key-way, g, in w hich 5.0) works a spline or feather indicated by dottedlines at g in Fig. 2, said spline or feather serving to operatively connect a driving pu1-' ley, G with the mandrel shaft. This ulley is held from sliding with said shaft, fitting it loosely between a pair of upstand- I ing posts, 71., which are made'fast with the" bed plate, E. It will be understood that the pulley, G is driven by the motor for the purpose of rotating the shaft, G, and the mandrel thereombut as said shaft and mandrel are moved endwise by a feed mechanism, to bepresently described, the pulley, G, is restrained by the posts, it, from sliding with said shaft, whereby the pulley which imparts rotary motion to the mandrel has recent? a fixed or, predetermined relation to the motor. r I

I designates a feed shaft which is journaled in appropriate bearings, e of the bed "plate, E, said shaft being preferably below the .mandrel shaft, G, parallel thereto and extending looselythrough the members, ,7, of the traveling carriage. It is preferred to provide a coarse male thread, 23,011 this-feed shaft, and with said :male thread engages a 'feed lever or traveler, I. Said] traveler is pivoted at one end, as ate" to the'carriage, see Fig. .6, and the leveris notched at a point intermediate of its ends, as at i where- I noted that the carriage, while actuated by the spring, is ,controlledby-the feed shaft, and this shaft is'loperatedbvthe motor, the func- "tions of said motorbeing, mainly, to rotate the mandrel and, the feed shaft.

It is evident, that the' lever, to which the spring is attached, may be lifted by hand from engagement with the screw shaft,-for the purpose ofv moving the carriage without hindrance from the'shaft in. one direction or the other, thus permitting the carriage and the record to be easily and quickly returned to a starting position.

The feed shaft, 1, is provided with a pulley, P, which is adjacent to and below the pulley, G on the mandrel shaft. Said pulleys, G I, are drivenby belts, G 1 see Fig. 3, said belts being operated by pulleys G I, of the motor, see Fig. 4.

p The combined horn and reproducer, C, is

of the shape more particularly shown in Figs. 1 and 2, said horn and reproducer being constructed as disclosed in my prior patu ents and in a copending application filed on even date herewith, Serial No. 394586. The element, C, (is provided with a plurality of styli, c, which are fixed'to the base of the reproducer, near the closed rear .part thereof, and said reproducer-is mounted for adjustment longitudinally of the casing, whereby either of the styli, 0, may be brought into gigagement with a record on the mandrel,

he reproducer is provided at its front 5 portion with a supporting bracket, J, the upper part of which is connected pivotally at, j to a plate, j, the latter being fixed to a rib, c, at the mouth portion of the'reproducer. This supporting bracket is foldable chine, and is adapted to'be stored-within the compartment, B, of the portable case; The supporting bracket is adapted togbe'fitted adjustably on the portable case, '-A,' .byf .ny

suitable means, butit is preferred-to'c on-I struct said su'pportin hold the reproducer,

bracket in a'; wayto ducer, while permittin' it"to Vibrate on the "horizontal axis afi'orde by the piyot,'j. As

I are attached or made-integral with a plate,

shown in Fig. 1, the supportingbracket, J, is provided. with .a longitudinal socket, 1' in which 'is adapted to be" fitted eitherof the supporting pins or sterjns,.J'. 'SaidstemS J ,'and thelsteins arejspaced on; said plate at intervals corresponding to the intervals between thestyli, 0-. The plate, J is fastened to the casing,A,in a suitable way, and the upper: edge of said plate projects above the corresponding edge of the casing. The bracket, J, is providedwith an angular foot- -piece, J which is forked as'at 7' so as to embrace the projecting top edge of the plate,

J When the reproducer is mounted for the bracket, J, to fit on the first stem}, J,

the forked foot, J engages with-the plate,-

J and the first stylus, c,is adapted to rest ,on the record of the mandrel, G. To bring the second stylus into position for operation,

the bracket, J, and .the reproducer are lifted so as to withdraw said bracket from the first stem, after which the bracket may be slipped over the second stem, J and locked into position for the foot to again engage with the plate, whereupon the secondflstylus is in position for coiiperation with the record. This adjusment of the reproducer and its supporting bracket may be performed to bring the third stylus into cooperative relation with the record, but it is to be noted that in either of the several positions of the reproducer the foot, J of the bracket is adapted to engage with the plate, J for holding the reproducer against sidewise movement. if j h In F igs: 4 and-5 of the drawings, 1 have shown one form .of motor which has been found to give good results in practice, but it is to be understood that I' do notintend to restrict myself to the use of any particular form of .motor, f r the reason that said motor may be modifi d wide limits. As shown, the driving spring,

. K, is anchored at oneend with-in thecasing,

D, but the other end of this springds'made fast with a disk or drum, is, or said, end. of the spring may be-secured rigidly .to th main drivmg'shafhL; Said shaft'isinoun I .ed in suitablebearings-withinthe casing, D, a and inone' -sideof the -c 'asing,D., or-the port ablecase, A, is an opening, Z,.which is'infrom vibration side- I wise, and at the same time, secure the ne'ces I i sary' longitudinal adjustment; ofthe repro--, rigidly secured the driving pulley, I wh1chwoperates'the feed shaft, I, at the required the belt, (i for rotating the mandrel is car-.

ried by the shaft, N, and the. shafts, L, N,

and changed within alinement with the end portion of the. main shaft, L, whereby a key or crank maybe inft'roduce'd through said opening and engage f'with anend portion of the shaft, L, for the purpose of turning the latter in order to place the driving spring, K, under tension. As is usual in the art, a detent mechanism,

'{such-as apawl and ratchet (not shown) :is employed for vhOIding'rthe driving spring 1 against unwinding. on this shaft, L, is"

speedg Said'shaft, L, is provided with a geangp, which meshes with a pinion, m, on I a counter shaft, M, and this counter-shaft is'provided with' a gear,- n, which meshes with: a pinion,' n,, onashaft, N. g'aidshaft is provided w1th agear,- o',.-- hav'mg intermeshincr engagement with a plnion, 0', on a.,"'

short shaft operating the centrifugal fgovernor mechanism, 0, the latter being jof'any suitable orpreferred construction. Said governor operates a brake disk, p, with which is adapted to engage a suitable form of. regulator for cbntrolling the speed of the motor, and consequently the speed of the pulleys which operate to impart the sliding and "rotary movement to the mandrel, G.

The driving are so arranged for operation that the carriage, F, will be moved endwise at the required speed and the mandrel, G, will be operated at a different speed, whereby'the record is moved endwise androtated simultaneously to operate the reproducer.

One of the important features of my new machineis a combined reproducer support I U i and stop mechanism for .themotor, said device operating to lift the r'eproducer from the record simultaneously with thestoppage' of the motor, and vice versa, said mechanism operates to start the'motor simultaneously with the adjustment of the reproduce'r into ous devices may be employed for performing this function, but in Figsi and 5of thedrawings, I haveshown a simple and efl'ecf I tive means for this purpose. A brake lever, P, is arranged-within themotor'ca'smg, 1D, and said lever is fulcru'med at p on a a depending arm, 9, which carries the'brake ward to the top portion, (i ofthe motor casing, and said end,{ of the lever is conpulley, G, which operates coiiperative relation with the record. Varit I fixed 1 bracketlarm, p; ;The lever is provided with nected'b'y a. screw, r, 'witha slide, R, elatif ter resting;upon the top, d, of said motor casing. i, Said-,slide' isiprovidedon its nnder-" side ,withs jafri b, 13f arranged to work-in a s1dt,.. r bf the motor casing, a d the slide is equipped with a bent arm, S, which extends upwardly" from the slide, and is preferably porting said reproducer in a raised. position '15:

curved to forma seat on which is adapted to rest the underside of the reproducer C. The slide is movable in the slot, 2, of he motor casin and the range ofadju'stment'of the slide 1s regulated by a stop, 8, which is fitted in the slot, 1*, and is adaptedto be fixed at ,difierent points therein by a screw, 8, said stop being in the path of the slide, R. The

slide, B, may, be moved in the slot, 1' for the purpose of adjusting theseat, S, below the reproducer, C, for thepurpose of supwherein the styli are above thepath of the record, substantially as shown in 1, "said reproducer turning on the pivot, j, when the rest, S, is thrust beneath it. Said inward movementof the slide and seat turns the lever, P, on its fulcrum, p, and moves a the brake shoe, q, into engagement with the g brake disk, 3),- whereby the inward movementjof the slide,,R, simultaneouslybrings theseat,.S, intoengagement withthe reprogovernor, O, and the motor. The reproducer is adapted to be supported by the seat, S, in a position whereln the styli, 0, are above'the record, and as the mandrel, G, is

at rest, a record may be withdrawn from said mandrel and a new record placed thereon, such interchange of the records being effected without danger of scratching or inutilating the records.

The mandrel, G, and the reproducer, C, are at right angles to each other, said reproducer extending lengthwise of the portable case, A, and'said mandrel being moved end- -wise in a path at right angles to the reproducer. Such arrangement and operation of the parts is quite desirable when the entire 7 machine is to be-carried or packed in a portable case, but it is to be understood that the invention is not confined to the employment of a record mandrelrnovable in a path at right angles tothe axis of a reproducer. In Figs. 7 and 8 of the drawings, I have shown a phonograph wherein the cylindrical end- -wise movable mandrel is arranged in a parallel relation to the reproducer, the said mandrel being movable lengthwise in a path i' parallel to the longitudinal axis of said re-' godu'cer. The mandrel is carried by a shaft,.

which is mounted in a carriage, F, and

' said carriage is moved endwis'e by a-feed shaft while the mandrel is. rotated from the 1 motor by a pulley, all as heretofore de-' 60 scribed. The reproducer, C, may be equipped witha single stylus, c, or with a plurality of styli, and said stylus of the reproducer is adaptedt'o rest onthe record, Z, at a point located to one side of the vertical plane of the mandrel shaft, see Fig[ 8. This relation. of the reproducer to themandrel prevents ducer and. applies the brake shoe, 9', against the disk, p, for. the purpose of arresting the the stylus from'sliding in one'dire'ction ofl the record, but the movement of the reproducer in the other direction is limited by a suitable anchor herein shown as an arm, T,

one end of which is pivotally connected as at t to the reproducer, while the other end is pivoted at t to afixture, T, adapted to be fastened to the motor casing, D.

The apparatus shown in Figs. 7 and 8 is operated in practically the same way, and by the same means, as the structure shown in the other figures of the drawings, except that the record is moved endwise in a path substantially parallel to the longitudinal axis of the reproducer and horn. In this connection attention is called to the fact that the record mandrel is mounted on the carriage, F, for movement below and length-' wise of the reproducer and horn, and in connection with the last named element, I em ploy the combined support and brake. The support, S, of Fig. 8 is adapted for engagement with the arm, T, for; the purposeeof lifting the arm and the reproducer when the brake is applied to arrest the motor, but areverse operation takes place, as heretofore,

described, when the support-and brake are adjusted,-whereby the support lowers the reproducer on the record simultaneously with the opera'tionof releasing the brake.
