Abstract: 7424. Sothen, R. von. April 7. Typewriters.- Relates to means for facilitating the writing of tables or forms and also to the filling-in of bills, invoices, &c. when a second sheet called the booking-sheet has to be written upon at the same time. A cylindrical pattern, cooperating with an index on the frame, is mounted to rotate with the platen and is provided with all the indications necessary to fill in the form &c. The platen a is mounted in a carriage b running on rails on the machine frame and having a scale f co-operating with a fixed index g. To the axle of the platen is secured a pattern roller k over which is placed a cylindrical pattern m. The pattern is held in position by a pin n on the flange of the roller k and by two pins p<1>, p<2> on a spring-pressed lever p. An index s is mounted on an arm r projecting from the carriage frame. When a form such as that shown in Fig. 9 is to be filled in, a pattern bearing the same wording or a part thereof is used, being provided with numbers 65, 14, &c. to indicate the scale divisions at which the entries are to be made. Other numbers, which may be written in a different colour, indicate the tabulator stops which are to be used. A set mark t on the pattern enables the form to be brought to a position corresponding with that of the pattern. The pattern roller may be solid and may be placed inside the carriage frame, and, in the case of a long platen, on the platen itself. Two or more patterns may be used, and for writing long forms a spiral pattern is employed. The pattern may be engraved or written upon the roller, or may be provided on a strip of paper which isattached to the platen or to the pattern roller. A cover of glass, celluloid, &c. may be used. The pattern roller may be geared to the platen so that the platen makes several revolutions for each revolution of the pattern or vice versa. Figs. 11 and 12 show a device suitable for filling-in booking-sheets together with the forms. The pattern is provided with the words "bill" and " booking.sheet and carbon " paper " to indicate the points at which these are to be inserted. After a bill is finished, the pattern is rotated backwards independently of the platen until the point marked " backward " on the pattern comes opposite the index. The pattern 1 is carried by a roller 2 fixed to a disk 6 having a sleeve 7, which turns on a fixed axle 8. A pinion 10 on the sleeve 7. is connected by gearing 19, 18, 13 with the shaft of the platen. The wheels 19, 18 are removable and can be replaced by others to vary the velocity ratio. To enable the pattern roller to be thrown out of gear, the wheels 19, 18 are journaled in a plate 21 which can be rotated round a pivot 22. The disk 6 is provided with teeth which engage with teeth on a second disk 9, which is mounted loosely on the sleeve 7. A spring 36 presses the disks 6, 9 into engagement, and a stop 37 on the disk 9 is adapted to engage with a stop 26 on the plate 21. The disk 6 is provided with a casing 31 to which is attached one end of a spring 33, the otber end of which enters one of a number of recesses 35 in the axle 8. After each bill has been written, the pattern is brought back by rocking the plate 21 and throwing the pattern roller out of gear. The roller is then rotated by the spring 33 until the stop 37 meets the stop 26. By means of the disk 9, the stop 37 can be adjusted with regard to the mark " backward" on the pattern. To enable'the pattern to be adjusted by hand instead of automatically, the disk '9 may be provided with a toothed boss which is engaged by springs on the disk 6, the spring 33 being dispensed with. In a modification, the pattern is placed on the face of a disk which co-operates with a fixed pointer.
