767,285. Copying-telegraphy. ADDRESSOGRAPH - MULTIGRAPH CORPORATION. April 1, 1954 [April 8, 1953], No. 11774/56- Divided out of 767,284. Drawings to Specification. Class 40 (3). The description is wholly included in Specification 767,284, but the claims relate to a facimile printing machine in which a conveyer feeds in succession data-bearing record forms to a position for scanning the data and transmitting signals to a printing position at which copy strip is continuously fed by strip-feeding means past a printing head at that position and in which means is incorporated for changing the ratio between the speeds of the conveyer and strip-feeding means so that the length occupied on the strip by the facsimile reproduction of a given length of record matter on the record form can be varied. In the arrangement described the driving sprocket for the copy strip is driven from a main shaft through two intermeshing gear-wheels which can be replaced by a pair of gear-wheels providing a different ratio. Specifications 690,164, 693,576 and 693,578 also are referred to.
