    Abstract: A selection mechanism is disclosed which employs a controlled steerable follower for selecting and following a cam groove in a barrel cam to cause relative translation between the barrel cam and the cam follower. The motion of the barrel cam while translating is converted into rotary motion to rotate a single element on a single element printer to accurately position a selected row of characters adjacent the print point. A similar follower is used to cause translational movement of the tilt cam and a bell crank and link arrangement is used to translate the lateral movement of the tilt cam to the type element. The control of the rotate cam follower is electro-mechanical wherein a signal is converted by a linear motor into a mechanical movement at a desired time within a cycle and thus dictates the selection to be made, when combined with an electrical signal to a solenoid for selecting the direction of rotation to which the cam translatory movement is to be converted. Means are disclosed which allows absorbing within the mechanism, of inertia shocks, such that the parts of the device may be made smaller and still withstand the forces required for selection.

    Abstract: A type element, which is mounted for movement along a writing line and has a plurality of types arranged thereon, is rotated through a differential mechanism to position a selected type at the printing position. The differential mechanism includes a first gear connected to the type element through a rotatably supported shaft. A sector gear meshes with the first gear to rotate the first gear in one direction in accordance with inputs to an arm on which the sector gear is mounted. The arm is pivotally connected by a pin to a link, which is pivotally mounted about the axis of the first gear, so that movements of the link change the position of the pin, which is the axis of rotation of the sector gear and is intermediate the sector gear and the input end of the arm, to rotate the first gear in the opposite direction. The inputs to the link and the arm are supplied through separate lever arrangements, which may be actuated by a single driving means or by separate pneumatically controlled means.

    Abstract: A plurality of ancillary nonprint typewriter functions such as word space, tabulation, backspace and carrier return are at least partially performed by operating members carried by a movingtype-element carrier. The overall mechanism of the typewriter is significantly simplified by enabling selection of individual functions through use of presently existing character selection mechanism in combination with a special nonprint mode selection control.

    Abstract: A rotary-to-linear motion conversion device comprises a rotatable shaft (32) and an annular cam surface member (36) encircling the shaft (32) and pivotally mounted on a bracket (44) secured to the shaft (32). The member (36) is engaged by an arm (27) of a pivoted cam follower (26) biased towards the member (36). The portion of the member (36) diametrally opposite the pivot (40) engages a slider (48) rotatable with the shaft (32). The slider (48) engages a flange (56) and a collar (60). Between the collar (60) and a fixed stop (64) are four selectively withdrawable interposers (70, 72, 74 and 76) of increasing incremental widths. Two such devices are included in a typewriter character selection system to control tilt and rotation of a typehead. The tilt and rotate cam members are mounted so that they pivot to vary the cam rise. The rise of the cam is controlled by the interposers under the influence of the keyboard.
