    摘要: Impression control mechanism for regulating the impact velocity of a single element type carrier against a platen. The support for the type carrier is driven about a pivot by a cam to effect printing. The cam acts through one end of a control lever which end in turn supports and acts directly on a pin located on and spaced from the type carrier support pivot. The control lever is pivoted at its opposite end to an adjusting lever which is itself pivoted to move the control lever pivot and through its end acting on the pin to shift the type carrier support about its pivot establishing the rest position of the type carrier relative to the platen thereby determining the impact velocity of the type carrier.

    摘要: In connection with an escapement which comprises a flying dog which for causing each escapement step of the carriage reaches out counter to the letter feed direction, there is provided a device which incidental to carriage return motion is operated by friction drag influence to block first said dog against outreaching movement and then to disengage said dog, the device being effective by a short advance movement of the carriage following the return movement to reapply the dog. The device is also operated by the tabulation control mechanism for durations of tabulating runs but not resultant to friction drag influence.

    摘要: A typing rate control for type bar typewriters to permit the realization of optimum overall typing rates wherein the code identification of a selected type bar, coded according to its position in a type basket, is held stored and is operative to call and cause the type bar it represents to print. The relative type bar position of the next to be called type bar and that of the type bar position in storage is ascertained by high speed counting logic circuitry and used to delay the call of the next type bar only over that time interval necessary to assure that the previously called type bar is out of the way.

    摘要: A type head having circular rows of types forming curved columns, is rotated by a transmission about a first axis at the centers of the circular rows of types, and angularly displaced about a second axis for selecting a type of a curved column. The transmission includes a driving gear and a driven gear having curved meshing teeth located at a point of the second axis, so that the gears remain in meshing engagement when the type head with the driven gear is angularly displaced.

    摘要: A typewriter ribbon arrangement has upper and lower portions which are supported on a carriage for movement with a single element printer. The upper portion contains the supply of ribbon and is removably attachable to the lower portion which is fixedly mounted on the carriage and has separate drive mechanisms for use with an upper portion having a cloth ribbon or an upper portion having a carbon ribbon. Each upper portion carries a pivotally supported ribbon lifter so they may be interchangeably attached to the lower portion without further threading. The upper portion for a cloth ribbon has spool-supporting spindles which are drivingly coupled to an indexing ratchet wheel drive mounted in the lower portion, and the upper portion additionally carries a pair of drag levers for keeping the ribbon taut and a pair of tension arms for sensing the tautness of the ribbon to operate a ribbon reversing means mounted in the lower portion when a spool carried by a spindle becomes fully wound.

    摘要: A type action of a power driven single element typewriter is provided with a storage arrangement enabling type characters to be successively printed in response to the successive operation of corresponding type keys even though the type keys are operated prior to the completion of a previously initiated printing cycle. The orienting movement of the printing element is determined by pawls moved to an operating position by the operation of a type action for engagement with a moving member undergoing a predetermined stroke. The orienting pawls are operably engagable with the moving member only at the beginning of an orienting movement of the single print element, and orienting pawls which are moved to the operating position after the beginning of an orienting movement are resiliently maintained at the operating position for operable engagement with the moving member upon completion of the previous orienting movement.

    摘要: Type characters arranged in columns on a rotatably driven print drum of a high speed printer are selectively impacted by print hammers which are pivotally supported for striking the print drum. Each column of type characters defines a print position along a print line, and the number of print hammers is only a fraction of the number of print positions along the print line. To enable type characters to be printed at each print position, the print hammers are disposed for movement in slots provided in a guide member which is movable parallel to the print line to flex the print hammers sideways to impact type characters of adjacent columns on the print drum.
