摘要： A motion mechanism in a type printer, wherein the axial displacement of a type drum relative to a printing hammer for setting the required type in position opposite the hammer, and the axial movement of both hammer and type drum for obtaining a new printing position on the sheet, is effected by means of a cord system which consists of a single cord, a type of endless chain. The cord runs over pulleys arranged at each end of the line to be printed, such that the cord is divided into four cord parts extending substantially parallel to the line on the sheet, one cord part supporting the hammer, and one supporting the type drum. At one side, two pulleys are arranged in spaced relationship on a plate which is mounted pivotally about an axis lying intermediate the rotational axes for the two pulleys. Furthermore the cord co-operates with a driving motor operating on that part of the cord which leads to the hammer. Setting of the hammer to a new printing position on the sheet is then effected by displacing the whole cord in its length direcion by means of the driving motor, whereby the hammer and the type drum will move equal distances. Setting of the type drum to a posion with a new type opposite the hammer is made by pivoting the mounting plate for the pulleys, whereby the type drum only is moved, while the hammer is held fixed.

摘要： A novel print head and platen configuration for a high speed printer is disclosed wherein the print head is a hollow cylindrical shape fabricated from a material which is measurably softer than the material used in the platen assembly. The print head is easily removable from its supporting structure. The hard platen has an appreciably long life and together with the print head assembly markedly improves on the print definition of the underlying printed copies.

摘要： A serial printing machine having a platen and a print carriage, head assembly having a type wheel with a plurality of lines of type, means for moving the type wheel vertically with respect to the platen to select the desired line of type and means for moving the type wheel horizontally to select the desired character; a pair of endless ribbons which are selectable so that only one of them is in printing position between the type character and the platen at any particular instant; a holding coil positioned such that when current flows in the coil, the type hammer is held out of contact with the type wheel; a pair of rails of high magnetic permeability running laterally, essentially parallel to the platen, a plurality of series connected coils wound around high magnetic permeability supports between the rails such that when current flows through the coils, a magnetic field is established which stores potential energy in the type hammer assembly; when the current in the holding coil is turned off and the potential energy is released, the type hammer moves into percussive contact with the type wheel to thereby cause the selected character to be printed.
摘要翻译：一种具有压板和打印托架的串行打印机，具有多个类型的类型轮的头组件，用于相对于压板垂直移动型轮的装置，以选择所需的类型和用于移动水平选择所需字符; 可选择的一对环形带，使得它们中的仅一个在任何特定时刻处于类型字符和压板之间的打印位置; 保持线圈定位成使得当电流在线圈中流动时，类型的锤被保持与型轮不接触; 一对高磁导率轨道，横向运行，基本上平行于压板，多个串联连接的线圈缠绕在轨道之间的高磁导率支架上，使得当电流流过线圈时，建立磁场，其存储势能在锤头组合中; 当保持线圈中的电流被关闭并且势能被释放时，类型的锤移动到与型轮的冲击接触中，从而使所选择的字符被打印。

摘要： A character supporting type shell for use with a character-bycharacter printer is disclosed. The shell is constructed of a material and has a shape that cause it to have rotational and longitudinal rigidity when rotated and longitudinally reciprocated about and along an axis, respectively. In addition, the shell has radial resilience so that it is deformable when acted upon by a force in an appropriate direction and of an appropriate magnitude. The resultant structure is one which has a weight considerably less than prior art devices and also a reduced inertia. The last-named factors contribute characteristics which permit a greater printing rate than previously available.

摘要： Selectors for a printing machine having a plurality of typecarrying wheels mounted in a printing carriage. A transversing selector selects a particular type wheel out of all the type wheels and a rotary selector selects a particular type out of all the types carried by the selected type wheel. These two selectors comprise a toothed rack, means for imparting to said rack a reciprocating movement, a plurality of pinions toothed around two opposite sectors and untoothed around two sectors interlaced with the previous sectors and engaging with said rack except when one untoothed sector is opposite the rack, a plurality of two arm levers pivotally mounted respectively on said pinions and terminated by a toothed-shaped extension at both ends of the arms thereof, a plurality of projections along the rack selectively cooperating with the lever teeth, a plurality of electromagnets respectively associated with said levers, means for selectively placing one of the teeth of the levers on to the path of the rack projections and for selectively allowing the pinions to rotate a half turn and means for converting the discrete rotation angles of the pinions of the rotary selector into a digitalized angular movement for positioning the type-carrying wheels and the discrete rotation angles of the traversing selector into a digitalized rectilinear movement for positioning the printing carriage.
