Definitions

  • My invention relates to the transmission of pictures, and has for its principal object the provision of an improved apparatus and method of operation whereby a picture hearing sheet of any desired length or Width may be readily transmitted from one point to an-- other.
  • Figs. 1 and 2 respectively illustrate a picture transmitting device and a picture receiving device constructed in accordance with my invention, and Figs. 3, 4 and illustrate diflerent ways in which the transmitting and receiving sheetsmay be fed through these devices.
  • Fig. 1 illustrates a continuous facsimile transmitting apparatus including a pair of stationary cylindrical supports 1 and 2 between which the picture bearing sheet 3 is fed by any suitable means. Light from a source 4 is applied to the sheet 3 either through a lens 5 or through a lens 7. The repicture transmitting ap t 1928. SeriaI'No. 204,714.
  • flected light is transmitted from the sheet 3 to a light responsive cell 8 through a chopper 9 driven by a motor 10, a hollow shaft 11 coupled to a motor 12 by means of gears 13 and 14, and either a prism 15 and a lens 16, or a prism 17 and a lens 18.
  • the lenses 5 and 7, he lenses 16 and 18 and the prisms 15 and 17 are mounted on the hollow shaft 11.
  • the sheet 3 and the lenses 16 and 18 are moved with respect to one another in such a way that the light reflected from the elemental portions of the sheet 3 is transmitted throu h the shaft 11 first to the chopper 9 which Freaks it up into successive impulses and then to the light responsive cell 8 which is utilized to modulate the impulses transmitted by a radio transmitter 19 of any suitable type.
  • the support members 1 and 2 may be omitted ifthe paper is moved in some other suitable way as shown in Figs. 4 and 5 for example.
  • the carrier wave thus modulated in accordance with the light reflected from the elemental portions of the sheet 3 and radiated by the transmitter 19 is received through a radio receiving apparatus 20 (see Fig. 2) and is utilized by a to produce a light which is modulated in accordance with the shade of the sheet 3.
  • a receiving sheet 22 is supported between the members 23 and 34 and this modulated light is transmitted to it through a hollow shaft and either a prism 26 and a lens 27 or a prism 29 and a lens 30.
  • a motor 31 similar to the motor 12 of the transmitting device is coupled to the hollow shaft through gears 32 and 33. Any suitable means may be provided for moving the sheet.
  • Fig. 3 shows one suitable apparatus for feeding the receiving sheet 22 between the supports 23 and 34 past the slot 28.
  • This apparatus includes a pulley 35 which is geared to a driving motor 36 and is arranged to cooperate with pulleys 37, 38 and 39 to move a pair of friction belts 40 and 41, in contact with opposite sides of the receiving sheet.
  • a similar receiving sheet 43 may be fed between the opposite halves of the cylindrical concentrated light source 21 supports 23 and 34 in exactly the same manon said sheets in a plurality of difierent dinor as the receiving sheet 22. Under these rections.
  • Fig. 4 shows a movable support member which is provided with a T-shaped member 51 arranged to be moved to and fro in a stationary member 52 by any suitable means such as a rack and pinion.
  • the sources of light which are circular in form are shown at 53 and 54 and current is transmitted to these sources from a battery 55 through slip rings 56.
  • Fig. 5 shpws a further modification in the means for supporting and moving the receiving sheet 22.
  • the sheet is mounted within a cabinet 57 located in a 7 dark room and is fed through a semicircular slot in the bottom of the cabinet by means of pulleys 58 and 59 and rolls 60 and 61 which are coupled to a driving motor 62 through gears 63 to 66.
  • This modification is similar in other respects to those previously described.
  • An apparatus including means for continuousl moving a light sensitive paper, a source 0 light, and a system including a plurality of lenses arranged to be simultaneously rotated about an axis parallel with the movement of said paper for projecting light from said source upon said paper, said lenses bemg so arranged that only one of said lenses projects light upon said paper at any given instant.
  • An apparatus including means for continuously moving a plurality of light sensitive members, a stationary source of light, and a system of lenses arranged to be rotated for projecting light from said source upon said members whereby a plurality of records are produced.
  • Receiving apparatus for simultaneously producing a plurality of records including means for movlng axially a plurality of concentrically curved light sensitive sheets, a source of light, and rotatable optical means including a plurality of similar lenses arranged to direct the light from said source
  • rotatable optical means including a plurality of similar lenses arranged to direct the light from said source
