Abstract: There is shown an inking apparatus for stamping on a localized area, and with a speedy application, a selected reproduction to a travelling or advanced product. This inking roller is free-turning with a light brake to prevent free wheeling. A four-bar linkage is used with two eccentrics. One eccentric is preferably rotated with at least twice the revolutions of the other eccentric. The four-bar linkage carries on an extending end of a first bar the stamp which is moved into peripheral engagement of the inking roller and then to the surface of the product. The movement of the stamp is in a path prescribed by the eccentrics and the four-bar linkage. The stamp in its peripheral engagement with the inking roller causes said roller to be inched forward rotationally to present a fresh surface to the stamp when next brought to the inking roller.

Abstract: A multipoint recorder has a multicolor ink cartridge arranged to be selectively aligned with a recording head having a plurality of selectively energizable recording elements whereby a color from the multicolor ink cartridge is selected for printing by the recording elements. A fixed color operation of the recorder enables a recording to be made in a single color by maintaining a preselected alignment of the recording head and a desired color in the multicolor ink cartridge. Alternatively, the color of the recording can be selectively altered at any time to produce a multicolor recording by selecting a corresponding color from the multicolor ink cartridge for each recording.

Abstract: This invention is concerned with a mosaic printer, for example, of the needle print head type which comprises a stationary print head and means for feeding an article, for example a web of paper to be printed, in a direction orthogonal to a row of print devices of the head and in synchronism with operation of the print devices so that, by selective operation of the print devices, the article is provided by the print devices with a pattern which constitutes visual data.

Abstract: The disposable printing head assembly includes a printing head frame structure fitted with a plurality of printing tips or pens. The printing head frame structure includes a plurality of separate store chambers including store material for containing the color printing material. The color store material may be the same or of different colors from one chamber to the other. At least one printing tip is disposed in each color store chamber. The printing tips are formed with different printing symbols such as a point, cross, star or circle.

Abstract: A simplified and compact typing machine to be incorporated in an electronic calculator has a type wheel for presenting different numerals upon rotation. The type wheel is moved along a line of digits, i.e., laterally and in the generally horizontal direction, for typing successive numerals and the typing is performed when a hammer head is swung, or the type wheel is rotated, by the movement in one direction of an acting rod of an electromagnetic relay. The same relay acting rod also laterally moves the type wheel in the direction of the line of digits, on its return motion, by a distance corresponding to the space of one digit.

Abstract: A serial disk printer which includes an ink roll is disclosed. During printing, the print disk is continuously rotated at a constant speed as it moves across the print line. The motion of the carrier across the print line does not begin until rotation of the print disk has been brought up to speed. In order to avoid unnecessary delay, the rotation of the print disk is not immediately stopped at the end of each line of printing. Instead, after each line of printing the carrier is returned to a home position and the disk is rotated for several seconds so that in the event printing of another line is required shortly after the completion of a line of printing the disk is still rotating and there will not be any delay before printing can begin. Ink is applied to the print disk by an ink roll which is in contact with the print disk. A mechanism is provided to lift the ink roll from the print disk while the disk is idling in home position. Thus, there is no wear on the ink roll while it is in home position.
