Latest Patents

One of his latest inventions is the Linespacing Apparatus. This apparatus features a slip clutch assembly driven by an electric motor. The slip clutch assembly includes a face cam that drives a linkage, which indexes a platen to linespace it effectively. The design incorporates an abutment portion that halts the motion of the linkage abruptly, while the slip clutch assembly prevents bounce or recoil, promoting smooth operation. Additionally, the linkage can be adjusted by an operator to vary the rotation of the platen during each operating stroke.

Another notable patent is the Platen Variable Apparatus. This invention allows for rotatable adjustment of a platen in step increments and fine amounts within a typewriter. The apparatus consists of a hub member that is rotatably mounted on a platen extension, featuring teeth that intermesh with a flexspline fixed on the extension. A coarse adjusting member is coupled to the platen extension, enabling positive rotation in controlled step increments. Furthermore, a rotatable fine adjusting wheel utilizes an internal wave generator surface to move the flexspline relative to the hub member, allowing for precise adjustments.
