- a read-write assembly disposed adjacent to said cylinder and the sheet of paper carried thereby,
- said assembly including two manually operable levers, one for positioning said assembly with respect to said cylinder and one for setting said assembly in its read or write operating mode.
- 2. The machine defined in claim 1 and including a belt mounted on said housing to reciprocate back and forth, said assembly being secured to said belt whereby it is carried back and forth along said cylinder.
- 3. A facsimile machine comprising
- a housing,
- a cylinder, in said housing adapted to carry a sheet of paper on which a message is to be written or which carries a message to be read,
- a drive belt, and
- a read-write assembly disposed adjacent to said cylinder and the sheet of paper carried thereby,
- said assembly comprising
- an insulating block,
- a light chamber in said block aligned with a portion of said cylinder,
- a first lever pivotally mounted on said block and including a portion adapted to engage said belt, and
- a second lever pivotally mounted on said block and including a portion positioned to operate a light switch, and a second portion adapted to operate means for blocking and unblocking said light chamber in said block.
- 4. A facsimile machine comprising
- a housing,
- a cylinder, in said housing adapted to carry a sheet of paper on which a message is to be written or which carries a message to be read,
- a drive belt, and
- a read-write assembly disposed adjacent to said cylinder and the sheet of paper carried thereby,
- said assembly comprising
- an insulating block,
- a light chamber in said block aligned with a portion of said cylinder,
- a plate pivotally mounted on said block and adapted to block or unblock said light chamber,
- a first lever pivotally mounted on said block and including a portion adapted to engage said belt, and
- a second lever pivotally mounted in said block and including a portion positioned to operate a light switch, and a second portion adapted to operate said plate for blocking and unblocking said light chamber in said block, depending on whether a read or write operation is to be performed.
- 5. A stylus assembly for a facsimile machine comprising
- a rotatable shutter having a portion for blocking a light-receiving chamber in one position of said shutter, said shutter having a front surface and a rear surface,
- a pin projecting from said rear surface of said shutter,
- a rotatable bracket having, at its rear, a laterally projecting arm seated on said pin, and, at its front, a vertical wall,
- a two-position rotatable lever carrying a projecting post which engages said vertical wall of said rotatable bracket for rotating said bracket and thus said shutter to open or obstruct said light-receiving chamber, when in one or the other of its two positions,
- a second rotatable lever and a third rotatable lever mounted for rotation on a common shaft, said second lever carrying a post which engages said vertical wall of said bracket and which also can engage said third lever at a maximum rotation of said second lever, said third lever engaging a belt for transporting said assembly along a path of travel.
- 6. A facsimile machine comprising
- a housing,
- a cylinder, in said housing adapted to carry a sheet of paper on which a message is to be written or which carries a message to be read,
- a drive belt, and
- a read-write assembly disposed adjacent to said cylinder and the sheet of paper carried thereby and movable with said belt,
- said assembly including two manually operable levers, one for positioning said assembly with respect to said cylinder and one for setting said assembly in its read or write operating mode.
- 7. A facsimile machine comprising
- a housing,
- a cylinder, in said housing adapted to carry a sheet of paper on which a message is to be written or which carries a message to be read,
- an endless belt, and
- a read-write assembly disposed adjacent to said cylinder and the sheet of paper carried thereby,
- said assembly including two manually operable levers rotatably mounted thereon, one lever being rotatable to grip and release said belt to permit moving and positioning said assembly with respect to said cylinder, the other lever being rotatable for setting said assembly in its read or write operating mode.
- 8. A facsimile machine comprising
- a housing,
- a cylinder, in said housing adapted to carry a sheet of paper on which a message is to be written or which carries a message to be read,
- an endless belt, and
- a read-write assembly disposed adjacent to said cylinder and the sheet of paper carried thereby,
- said assembly including a stylus assembly for applying electrical charges to said sheet of paper when a message is being received, and a source of light for scanning a message carried by said sheet of paper when the message is being transmitted,
- said assembly also including two manually operable levers rotatably mounted thereon, one lever being rotatable to grip and release said belt to permit moving and positioning said assembly with respect to said cylinder, the other lever being rotatable for setting said assembly in its read or write operating mode,
- said other lever also moving said stylus out of contact with said sheet of paper when said assembly is moved manually with respect thereto, said other lever also operating to expose or block said light source.
- 9. A facsimile machine comprising
- a housing,
- a cylinder, in said housing adapted to carry a sheet of paper on which a message is to be written or which carries a message to be read,
- an endless belt, and
- a read-write assembly disposed adjacent to said cylinder and the sheet of paper carried thereby,
- said assembly including (1) a stylus assembly for applying electrical charges to said sheet of paper when a message is being received, (2) a source of light for scanning a message carried by said sheet of paper when the message is being transmitted, and (3) a rotatably mounted shutter plate for exposing or blocking said source of light, said shutter plate also being operable to push said stylus assembly out of contact with said paper at the same time that it exposes said source of light to said paper,
- said assembly also including two manually operable levers rotatably mounted thereon, one lever being rotatable to grip and release said belt to permit moving and positioning said assembly with respect to said cylinder, the other lever being rotatable for setting said assembly in its read or write operating mode,
- said other lever also moving said stylus out of contact with said sheet of paper when said assembly is moved manually with respect thereto, said other lever also operating said shutter plate to expose or block said light source.
- 10. The machine defined in claim 9 and including
- an auxiliary rotatable bracket coupled between one of said levers and said rotatable shutter plate.
