Application filed February 21, 1916.

To all whom t may concern:

Be it known that I, MELvILLn CLARK, a citizen of the United States, residing at Chicago, in the county of Cook and Stater of Illinois, have invented new and useful Improvements in Drive Mechanism for CombinedwPhonographs and Player-Pianos, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention is to combine in a single casing a phonograph mechanism and a` player piano mechanism, and-to arrange for driving the phonograph from the same motor which drives the take-up roll of the player mechanism. The invention consists in the features and elements of construction contributing to this result and their combinations described and shown in the drawings as indicated by the claims.

Fig. 14 is a detail view of the speed-controlling cam for actuating the brake and the reversing train.

It may be understood that this combined phonograph and player piano is designed primarily for rendering vocal or instrumental selections by means of the phonograph with piano accompaniment controlled by the. usual form of perforated note sheet, shown at 1, in Fig. l; the rotary recordcarrving table of the phonograph is arranged to be driven at a uniform speed from the same motor shown at 2, as is regularly provided for driving the take-up roll, 3, of the player mechanism. In order, however, that either the player piano or the phono,- graph may be operated independently when desired, it is necessary to make they driving conneetionssuchthat either mechanism can be driven alone from-the motor, 2.

This motor, 2, may beV of any convenient type fitted with a speed-regulatingv governor and speed-varying.means ;-it isshown in the drawings as a spring motor of substantial construction, and to render its relation to the other partssufliciently clear it musty be described somewhat in detail.V Referring to Figs. 11, 12, 13 and-14:, it will be noted that the motor is mounted just beyond the casing carrying the take-up` roll, 3. Its spring drum, 2, is geared to a small pinion, 2b, on

the shaft, 2C, carrying a gear, 2d, meshing with a pinion, 2e, on the shaft, 2f. From this shaft motion is transmitted through spiral gear.- ing to the so-called fly-ball or centrifugal governor whose mode of operation is well understood and Iwhose friction disk, 2g, is engaged by a brake, 2, whose adjustments serve to'eontrol the speed-,of the motor. The shaft, 2f,-also carries a gear, 21, meshing with a gear, 2k, which is carried-on an arm, 21, mounted to swing about the axis of the shaft, 2f, connecting the gear, 2, either with the gear, 2m, on the take-up roll shaft or with the gear, 2, for driving the pinion, 2, on the rewindv shaft. The brake, 2h, is carried by one arm offa bell crank lever,2q, whose other arm engages a cam slot, 2r, in a slidable control bar, 2S. whose movement ina direction parallel'to the axis of the take-up roll, 3, effects the-,adjustment offthebrake, 2h, for. varying the speed of the mOtor, 21, andv even for holding it at rest. A second cam slot, 2t, inthe bar, 2s, controls a bell crank,y 2, connected byfalink, 2U to the Patented Nov. 13,1917.

swinging arm, 21, which carries the gear, 2k, so that after the cam bar, 2S, has been moved from its Zero speed position to its maximum speed position by means of a hand lever, 2W, a further movement of the lever in the same direction shifts the gear, 2k, through its neutral position and inte mesh with the gear, 2, for rewinding the note sheet with the motor running at maximum speed.

Now referring to Fig. 2, the record-carrying table of the phonograph will be found indicated by a dotted circle at, 4, and the spindle of this table is shown in section at 5, carrying a friction pulley or wheel, 6, whose periphery contacts with the face of the friction plate, 7, secured to the end of a shaft, 8, at whose opposite end a spur pinion, 9, mounted near the adjustable journal, 10, of the shaft, 8, sta-nds'in position to mesh with the gear, 2d, on the motor, 2. As above indicated, this gear is normally connected in the train which draws the takeup roll, 3, but since the phonograph table, s'-, must be operated at a constant speed to avoid varying the pitch of the music produced, and since it may be necessary from time to time to slightly vary the speed of the take-up roll, 3, for synchronizing the phonograph music with the player accompaniment, it is no longer feasible to drive the take-up roll directly from the motor 2, when both mechanisms are to be operated by said motor, and motion is, therefore, transmitted to the take-up roll, 3, through a pinion, 11, on the shaft, 8, meshing` with a gear, 12, whose face, 12a, constitutes a friction plate in driving engagement with a friction wheel, 13, rotatively carried on a shaft, 14k, but slidable longitudinally thereof for varying its position on the face of the gear, 12, and thus varying the speed transmitted. The shaft, 14, carries a bevel gear, 15, meshing with a similar bevel gear, 16, on a horizontal shaft, 17, provided with a disengageable clutch, 13, connecting with the take-up roll, 3.` A yoke, 19, engaging the grooved hub of the friction wheel, 13, and carried on a slidably mounted stem, 19a, is arranged to be shifted through a bell crank, 20, and links, 21, by means of a handle, 22, which is accessible just below the take-up roll in the central open panel of the piano casing.

As to the operation, it may be understood that the governor brake, 2h, of the motor, 2, is first utilized for varying the speed of the phonograph table, it, to insure that the phonograph record will be rendered in correct tune with the `piano. Then by pressing the knob, 23, on the rod, 23, the latch member, 24, is depressed to release the lower end of the bell crank, 25, permitting its upper and horizontal arm, 25a, to swing downwardly and lower the stylus, 26, onto the phonograph record indicated at 27, in Fig. 3.

With the record standing at rest the stylus, 26, is placed approximately at the point at which the actual music begins, and the arm, 2.3, of the bell crank, 25, is then raised to lift the stylus, 26, just off the record, 27, i

the bell crank, 25, being retained in its position by the latch member, 2i, which automatically resumes the engagement illustrated in Fig. 3 under the tension of its spring, 2S. A small motor pneumatic, 29, connected to the lower end of the rod, 23, and thereby linked to the latch member, 211'-, is adapted to release the latch, 211, when collapsed, thus permitting the sound box, 30, and its stylus, 26, to be lowered by gravity onto the record, 27. Fig. (i illustrates diagrammatically the motor pneumatic, 29, connected with its primary pneumatic,'31, which is connected to a duco2. in the tracker board, 33, so that if. the perforated note sheet which is to control the playing of the piano accompaniment to the phonograph music be provided with a perforation positioned to uncover the duct, 32, at the proper point in the accon'ipaniment for the beginning of the phonograph music, the note sheet will serve to automatically bring the phonograph into action by thus actuating the motor pneumatic, 29, which releases the latch member, 21, and permits the stylus, 26, to engagethe record, 27. After ascertaining the correct speed for proper timing of the phonograph music and finding the proper initial position for the stylus, 26, the motor, 2, is first started at the ascertained speed and begins to revolve the table, 1l, and also the take-up roll, 3, driven through the medium of the friction wheel 13, engaging the face of the gear, 12; the note sheet, 1, being advanced by the rotation of the take-up roll, 3, and having an aperture register-iu g with the duct, 32, then automatically starts the phonograph music, and the operator can almost .immediately note whether the accompaniment should go slower or faster to be properly synchronized with the phonograph solo. Such synchronization is easily effected by shifting the friction wheel, 13, by means of the handle 22.

nlthough the perforated note sheet is especially cut to serve for controlling an accompaniment to a particular phonograph record, being preferably made by the automatic recording of the hand-played accompaniment of a competent artist, the lengthening or shortening of the paper note sheet, due 'to changes of hinnidity, may require that occasional adjustment of the speedcontrolling handle be made during the rendition of the piece to keep the accompaniment strictly synchronized. In addition to such changes of speed it may be desirable to arrange for temporarily varying the ratio of speed between the note Sheet, 1, and

the phonograph record, 27, and this may be effected automatically by means of a familiar' step-by-step device, shown in detail in my Patent No. 1,013,862, dated Jan. 9, 1912, and indicated in Fig. 3 at 34. This device includes a rack, connected by a` link', 36, to the bell crank lever, 20; a gear, 37, meshing with the rack, 35, is arranged to be fed step-by-step in one direction by a motor pneumatic, 38, and similarly in the opposite direction by the pneumatic, 39, said pneumatics being controlled, respectively, by ducts, 40 and 41, as indicated in Fig. 6.

Since the note sheet controlling the accompaniment is especially made to fit the particular phonograph record, 27, there will be a particular point in the note sheet corresponding quite accurately to the last note of the phonograph music, and immediately following this point the note sheet may be perforated at a position to register with a duct, 42, controlling the primary pneumatic, 43, corresponding to a motor pneumatic, 44, which is connected by a link, 45, to the lower end of the bell crank, 25, so that collapse of motor pneumatic, 44, will draw the lever, 25, back into the notch of the latch member, 24, in which position it will be retained, and in moving to which position it will raise the stylus, 26, out of contact with the record disk, 27, and thus throw the phonograph out of action.

Now if it is desired to operate the player piano mechanism without the phonograph, the phonograph mechanism is disconnected from the motor, 2, by slightly springing the shaft, 8, out of line far enough to disengage the teeth of the pinion, 9, from the teeth of the gear, 2d. This is done by shifting a cam lever, 46, mounted on the side wall, 2X, of the motor casing to a position in which its notch, 46a, enga-ges the pin, 47, of the slidably mounted journal bearing, 10, for the shaft, 8, and the notch, 46, being at the high point of the cam, it will be evident that this movement serves to separate the pinion, 9, from the gear, 2d. The notch, 46a, is only a slight depression in the face of the cam, but sufficient to retain the parts in this adjusted position.

The shaft, 8, being thus thrown out of service, the take-up roll, 3, can no longer be driven through the clutch, 18. The slidable member of the clutch, 18, is connected through a shifter rod, 49, with the slidable member of a clutch, 50, on the shaft of the motor gear, 2, so that as the clutch, 18, is disengaged the clutch, 50, serves to couple the shaft directly to the take-up roll, 3, and the movement of the shifter rod, 49, is effected by a slidable cam block, 51, connected directly to the cam lever, 46, as shown in Fig. 4. A follower roller, 52, on the end 0f the shifter rod, 49, engages the cam face of the block, 51, as indicated in Fig. 5, and is maintained in such engagement by a spring, conveniently disposed near the opposite end of the rod, 49, to react against the one wall, 53, ofthe tracker housing, 53. A link, 54, connected at one end to the cam lever, 46, and carrying at its opposite end a handle, 55, projecting through a slot in the wall, 53h, of the tracker housing, provides the manually engageable adjusting means for the cam lever, 46, and sliding cam, 51. It will be clear from Figs. 4 and 5 that when the lever, 46, is moved to the middle position of its range, that is, with the pin, 47, engaged in the notch, 46, the follower roller, 52, will ride on the highest part, 51, of the cam, 51, thus effecting crowding engagement of the clutch, 50.

dien the player piano is operated without the phonograph, it may be desired to use upon it such perforated note sheets as are provided for automatic control of the tempo by means of perforations positioned to register with the ducts, 40 and 41. Such perforations would effect actuation of the stepby-step device, 34, as fully described in my said Patent No. 1,013,862 and to render this operative for controlling the tempo there is provided a hook, 56, designed to engage an eye. 57, for connecting the link, 21, directly to the motor governor whose controlling lever is rigidly associated with the movable tempo index, 58, on which the eye, 57, issecured. This detail is shown in Fig. 7,

though the connection between the index,

58, and the governing devices of the moto'i, 2, are illustrated in detail in Figs. 11, 12, 13 and 14. But since the movement. of the link, 21., necessarily involves movement of the bell crank, 20, and with it a shifting of the friction wheel, 13, across the face, 12a, of the gear, 12, it is desirable to separate the frictionally engaged surfaces of the wheel, 13, and gear, 12, and this is automatically effected by a cam roller, 59, carried by the cam lever, 46, in position to encounter one end of a tubular thrust link, 60, slidably mounted on the shaft, 8, and connected by a lever, 61, with a push rod, 62, arranged to act against the center of the face of the gear, 12, to push said gear axially out of engagement with the friction wheel, 13, by slightly compressing its follower spring, 63. Since the push rod, 62, only comes into play when the shaft is disconnected from the motor, 2, the gear, 12, stands idle and is in no way embarrassed by the action of the push rod, 62, and the friction wheel, 13, is left free for sliding movement following the movement of the link 21.

Then it is desired to operate the phonograph alone and independently of the piano, the handle, 55, is moved through the entire range bringing the pin, 47, into engagement with the notch, 46", of the cam lever, 46. This vpermits thegear, 9, to move back into mesh with the gear, 2d, for operatively connecting the motor, 2, With the phonograph table, et. Simultaneously the cam member, 51, is shifted to bring its surface, 51h, into contact With the follower roller, 52, on the shifter rod, a9, and since this surface, 51h, is in a plane intermediate the planes of the surfaces, 51 and 51, respectively, it puts the shifter, 4H), into a position in which both the clutches, 1S and 50, are disengaged from the take-up roll, 3, so that the motor, 2, causes no movement of the take-up roll, 3. From this position of the cam lever, 46, the cam roller, 59, is carried below the shaft, 8, and beyond the end of the tube, 60, thereon allowing the latter to stand in its normal position With the thrust rod, 62, exerting no pressure on the face of the gear, 12.

vWhen the motor, is a spring motor it is normally kept Wound by automatic Winding devices, not shoivn, and connected with the pumping mechanism of the player piano, but when the phonograph is used for any considerable length of time Without the player mechanism of the piano the spring motor will of course run dovvn and must be reivound. Since the Winding shaft, (5f-it, extends to the end of the piano casing at 65, for convenient connection of the Winding clutches, 66, With the pumping mechanism in the loiver part of the piano case, it is a simple matter to provide reduction gears, 67, 68' and 69, connecting the Winding shaft, G4, with a short shaft, 70, and a emovable Winding crank, 71, just outside the end panel, 65, of the piano case.

As indicated in Fig. 3, the sound box, 30, of the phonograph connects through its tone arm, 72, With an amplifier, 73, opening directly into the back of the frame ivhich carries the take-up roll and note sheet spool. The sound-discharging opening, 7a, is arranged to be varied as to its size for controlling the volume of sound discharged therefrom by provision of a curtain, 75, shoivn mounted on a roller, 76, and carrying in its free end a Weighted rod, 77 Whose ends are guided in guideivays, 78, While the roller, 76, is arranged to be rotated through a train of gears indicated on Fig. 3 at 7 9, and manually operable through a hnurled knob, 80, conveniently located near the front of the frame and in the opening into which the note sheet spool is to be mounted.
