SPECIFICATION forming part of Letters Patent No. 609,268, dated August 16, 1898. Application filed December 15, 1890. Serial No. 374,759. (No model.)
To ctZZ whom it may concern:
Be it known that I, THOMAS A. EDISON, a citizen of the United States, residing at Llewellyn Park, in the county of Essex and State of New Jersey, have invented a certain new and useful Improvement in Phonographs, (Case No. 883,) of which the following is a specification.
The present invention relates to phonographs in which disk phonogram-blanks 0r recordingsurfaces are used and in which the record is formed in a spiral line on one face of the disk.
The invention consists in means for sup porting the blank and connecting it to the shaft by means of which the blank is rotated.
The invention also consists in means for moving the recorder, reproducer, and turning-off tool across the blank, whereby the op crating-point is caused to follow a spiral track; and the invention consists in the several features and combinations hereinafter set forth. In the accompanying drawings,which ill nstrate the improvement, Figure 1 is a plan View of the phonograph. Fig. 2 is an enlarged View, partly in section, of a part of the same;
Fig. 3 is a sectional view of the phonogramand Fig. 5 shows means for adjusting the re,
corder and reprodncer.
The phonograph-shaft 1 is rotated at the proper speed by any suitable means. (Not shown.) At the upper end of the shaft is a holder or mandrel 2 for the phonogram-blank 8, preferably made entirely of recording ma; terial, as shown in Figs. 3 and 4. The holder, which is rigidly connected to the shaft, con; sists of a disk with a tapering extension 4:, as shown in Fig. 3, or of a disk with inclined sides, as shown in Fig. 4. The blank is formed with a corresponding tapering recess or opening, so that it may be readily placed and centered on the holder and held in position wholly by its frictional contact with the mandrel or holder.
5 is an arm carrying the recorder and re producer supporting ringfi and the turningoff tool 7. The recorder and reproducer are carried by a single diaphragm, as shown in Fig. 5, and as in my application Serial N 0.
330,789, filed November 18, 1889. hen the diaphragm is turned to change the points, the arm carrying said points may be tilted slightly to raise one point away from the blank. The arm 5 is pivoted at 8 to a vertical axis and at 9 to a horizontal axis, so that the arm may be moved across the blank or may be moved toward or away from the blank.
10 is a feed screw driven by a suitable motor (not shown) which may be connected to the screw by means of a worm-gear 11 or otherwise.
12 is a nut carried by arm 5 and cooperating with the screw. This nut has a shank in the end of which is a pin 13, which rests in and moves in the slot 14E in the cam-shaped rod 15. Rod 15 is held in a block 16, which can slide back and forth in the slot 17 in arm 5.
18 is a pin or handle by means of which 15 may be turned in its socket.
19 is a determining device pivoted to arm 5 and having an adjustable head, as shown and as heretofore described by me.
20 is a speaking or hearing tube, and 21 is a spring or brush which rubs lightly over the surface as the blank rotates and removes the shavings and dust therefrom. A chnte 22 may be carried by the turning-off tool to convey the shavings away from the blank.
' The above-described apparatus is used as' follows: The recorder and reproducer are adjusted away from the face of the blank and the turning-off tool is carried to the edge of the blank by moving arm 5 on its vertical pivot. The feed-screw isthen rotated and moves the turning-0E tool across the face of the blank and shaves oi the rough surface thereof. When the tool reaches the center of the blank, arm 5 is raised and the recorder adjusted into operative position, so that it extends below the cutting edge of -7. The recorder is then carried to the center of the blank, and 12 is placed in contact with the screw, and the recorder forms a spiral record in the well-known manner. By turning the screw in the opposite direction the recorder may make its record-from the edge of the blank toward its center. As arm 5 is moved by the screw the block 16 moves along in the slot 17 in view of the varying distance between the pivot and the screw and the nut 12 is allowed to turn slightly, so that the working face of the nut shall always rest properly on the thread of the screw. When it is desired to again shave off the surface of the blank, the rod 15 is loosened freely up and down in its support, so that it can move, and ,the arm 5 is moved toward the blank until the determining device 19, which has been previously put in the proper position relative to the knife 7, bears on the surface of the blank. Thenut then rests on the screw, and the camshaped rod 15 is turned slightly, causing it to bind in its socket and to be held in place. The determining device does not interfere with the working of the knife, since as the blank revolves the device is swung to one side.
What I claim isv 1. A phonogram-blank for phonographs made in the form of a thick disk adapted to be shaved off a number of times to receive new records, and provided with a central hole or depression formed perpendicular to and tapering toward the working surface, said hole or depression being adapted to fit a tapering support, whereby the blank will be centered and held in position wholly by friction, substantially as set forth.
2. A phonogram -blank for phonographs made entirely of recording material in the form of a thick disk adapted to be shaved off a number of times to receive new records and provided with a central hole or depression formed perpendicular to and tapering toward the working surface, said hole or depression being adapted to fit a tapering support,whereby the blank will be centered and held in position wholly by friction, substantially as set forth.
3. In a phonograph, the combination of a disk phonogram-blank or phonogram having a tapering opening, a tapering rotating mandrel for supporting and rotating said blank, a recording or reproducing device, support for said recording or reproducing device, pivoted soas to be capable of movement toward and away from the blank, and means for moving said arm across the face of the blank, substantially as set forth.
4:. In a phonograph, the combination of a fiat phonogram-blank or phonogram, a recording or reproducing device, an arm carryin g said device and movable toward and away from the phonogram-blank or phonogram, and a determining device for determining the adjustment of the arm relative to the phonogram-blank or phonogram, substantially as set forth.
5. In a phonograph, the combination of a fiat phonogram-blank or phonogram, a re cording or reproducing device, an arm carrying said device and movable toward and away from the phonogram-blank or phonogram and across its face, and a determining device for determining the adjustment of the arm rela* tive to the phonogram-blank or phonogram,
substantially as set forth.

8. In a phonograph, the combination of a disk phonogram-blank, a recorder or reproducer, a support for said recorder or reproducer, pivoted so as to be capable of movement toward and away from the blank and across the face of the blank, a feed-screw, and a nut-section carried by said arm and adapted to engage said feed-screw and whereby the recording or reproducing device is caused to move across the face of the blank, substantially as set forth.
9. In a phonograph, the combination of a pivoted arm having two prongs, a recording or reproducing device carried by one prong, a turning-off tool carried by the other prong, and means for moving said arm relative to the phonogram -blank or phonogram, substantially as set forth.
