(under subclass 365) Subject matter wherein a power-driven typewriter is provided with means for freeing a blockage caused by two movable parts of the typewriter tending to occupy the same space at the same time.
(1) Note. The most frequent occurrence of a jam results from two type-face* elements, each on its respective type-bar*, that arrive at the print-point* at the same time. Since a print-point accommodates only one type-face element, a jam will occur if two such elements tend to occupy the
print-point simultaneously. The mechanism of this subclass inhibits the actuation of one of the type-bars to prevent such an occurrence. In a typewriter that is not provided with such preventing means, or in a typewriter in which such a jam occurs despite said means, the mechanism effects the release of such a jammed condition.
