INVENTOR REGINALD T. FRIEBUS ATTORNEY Patented Sept. 13, 1932 UNITED STATES PATENT OFFICE REGINALD .l'. FBIEBUS, OF MONTCL AIB, NEW JERSEY, ASSIGNOB '.l.0 COLUMBIA PHONC- GRAPE COMPANY, INC., OF BRIDGEPOB'I, CONNECTICUT, A CORPORATION OF NEW YORK IEANS AND METHOD OF BEPRODUCING PICTURES 0B SCENES FROM RECORDED IMPULSE Application filed September 25, 1929. sena no. 394,999.
This invention relates to new and useful improvements in means and methods of recording a series of impulses and to means and methods of reconstructing sound or a visible picture from said recorded series of im ulses.
eretofore, the types of electric pick-ups in use have been too heavy to attempt to pick up as much as fifteen thousand vibrations er second, this bein required in television. In my application erial Number 364,897 Filed May '21, 1929, I have disclosed what I choose to call alight ray pick-up. The means and method disclosed in this application and in other applications'about tobe filed are capable of handling frequencies of the order of fifteen thousand vibrations per second and therefore make possible the reproduction or reconstruction of a scene or picture recorded in a spiral groove on a disc record.
It is therefore, an object of the present invention to apply the light ray pick-up principle to the reconstructing or reproducmg on a projection screen of a scene or picture recorded by a series of impulses.
A co-extensive object of the invention is to apply this principle of light ray pick-up to the recording of a picture or scene in the form of a series of impulses.
A further object is to provide a means and method whereby through the use of the principle of the light ray pick-up scenes or pictures may be recorded on and reproduced from a disc recorded in such a manner as to present them in colors when reproduced.
An additional object is to provide a means and method whereby through the employment of the principle of the light ray pick-up scenes or pictures may be recorded on and reconstructed from a record in black and.
white accompanied by sound or in colors, ac-
- companied by sound.
hmited to the embodiments shown. Many changes ma be made within the scope of the appended c aims and reference must there fore 'be hadto them for a definition of the limitations of the invention.
In-the drawings F 1g. 1 1s a more or less diagrammatic viewshowing-the invention used in reproducing a picture or scene in black and white Fig. 2 is a somewhat diagrammatic view showing the arrangement forrecording a scene or picture in black and white Fig. 3 is a similar view but showing the arrangement of the invention for recordingblack and white together with a. soundfrecording I a Fig. 8 a similar view showing a' record on which a scene is recorded in color thjer with a sound record.
Referring in detail to the draw' particularly to Fig. 1, at 10 is shown asuitable turntable mounted on a turntable shaft or spindle 11 driven by any means (not shown). On the turntable 10 is disposed a disc record-12 having a scene recorded thereon in the form of a series of impulses in a spiral groove.
Mounted so as to be disposed above the record 12 is a light ray ick-up device 13 the detailed construction 0 which is given in a co-pending application Ser. No. 394,998 filed Sept. 25, 1929. Briefiy,this pick-up 13 includesa supporting arm 14 mounted for pivotal movement both horizontally and vertically as indicated at 14 and 15, and carrying at its forward end a head portion 16 within which is mounted a light sensitive cell as for example. the photo-electric cell 17 The head 16 also includesa depending portion 18 in which is fitted a lens system comprising lenses 1811. To the forward side of the ick-up and maintain the housing 19 rests on the pin operates in a record follows :-Light, from a suitab e source 22,
through the is cast onto t e record and owing to the formation of the groove in the recording opera: tion, light and dark spots of various shades are formed in the groove and light reflected upwardly from the groove is passed through the lens system and onto the cell 17. Wires or conductors 23 connect the cell 17 with an amplifier indicated at 24 which in turn is connected by wires25 to a neon lamp 26. Between the neon lamp 26 and a projection screen 27 a scanning wheel 28 is interposed,
vthe scanning wheel being driven by a synchronous motor 29. It will be apparent that the picture or scene recorded on the disc 12 is reconstructed on the screen 27.
The recording of a disc such as 12 involves a rearran ement of parts and is shown in Fig. 2. ere, the object 31 to be recorded has interposed between it and an illuminating lamp 32 a scanning wheel 33 driven by synchronous motor 34. Light, reflected from the object is caught by the photo-electric cell 35 connected with an amplifier 36 as by conductors 37, the amplifier in turn being connected b wires 38 with an electric recorder 39. 'I his recorder, which is of any known construction, operates to engrave the record groove in a wax master 40 from which by proper method duplicate copies may be produced. From the foregoing it will be seen that there is but a slight c ange in the arrangement of parts when they are used for recording and reproducing.
In Figs. 3 and 4 is more or less dia ammatically illustrated the arrangement or re cording a scene or picture in color. The object 41 is, of course properlypositioned relative to the apparatus. As shown, the apparatus includes a light source 42 arranged to direct light rays against a scanning wheel 43 driven by s chronous motor 44. Difier ent portions 0 the object are illuminatedby these light re s and the reflected rays passing filter screens A, B, and C engage the,respective photo-electric cells A, B, and G. i
v Fig. 3 shows the employment of three sets of color screens and'three sets of photo-elec-' tric cells, the cells of the various sets being hooked into their respective circuits and electrically; connected to the amplifiers A2, B2,
and C2. Each amplifier is in turn connected with an electrical recorder of any desired construction. It will be understood that there is a color screen-in each set for each of the primary colors. Further it is to be understood that each recording instrument A3, B3,
and C3 records in a separate groove on a wax master 45. It will be obvious that different paratus of Fig. 5 is used. For this purpose three light ray pick- up devices 46, 47 and 48 as disclosed in my application Ser. No. 394,998 above referred to are employed. These picku s are the same as that shown at 13 in Fig. 1.
ach of the pick- ups 46, 47, and 48 is connected with a suitable amplifier, the amplifiers bein indicated at 49, 50, and 51.
From t e amplifiers through suitable connections 52, 53, and 54, the electrical impulses are carried to neon lamps 55, 56, and 57. From the foregoing it will be apparent that for each groove on the record there is a corresponding pick-up apparatus. Each of the neon lamps 56, and 57 is arranged forwardly of a scanning wheel 58 driven by synchronous motor 59, and at the opposite side of the scanning wheel 58 is disposed a projection screen 60.- Disposed etween the respective neon lamps 55, 56, and 57 are color screens 61, 62, and 63 corresponding respectively to the color screens A, B, and C. of Figs. 3 and 4. It will now be apparent that the features of various colors in the object are recorded in the respective grooves and that the various colored features are independently reproduced and a composite picture formed on the screen 60.
In Fig. 6 is shown an arrangement for re-.
I provided. The sound or speech reproducing system includes a light ray pick-up 13 operatin through an amplifier 64 to a loud spea er 65. The scene or picture reproducing system includes a light ray pick-up 13 operating through an amplifier 66 connected with a neon lamp 67. The neon lamp 67 is positioned relative to a scanning wheel 68 driven by synchronous motor 69 and in therear of which is positioned the projection screen 70. This picture or scene pick-up mechanism is the same as that shown in Fig. 1.
In Fig. 7 is shown in plan view a portion of the record on which a scene is recorded in the groove 71, sound being recorded in the groove 72. These grooves as shown are in the form of parallel spiral lines and the record is such as to be used in connection with the apparatus of Fig. 6.
In ig. 8 is shown a similar view ofa portion of a record on which a scenehas been recorded in color in combination with sound. The scene grooves are indicated at 71, 72,and 73, and the sound groove is indicated at 74. These grooves, it will be noted, are in the form of four parallel spiral lines.
