Abstract
Perfeccionamientos introducidos en un dispositivo para el mando semiautomático del movimiento del carro o del porta-tipos de una máquina de escribir, para el centrado de grupos de signos en una línea, caracterizados porque está previsto un interruptor de funciones que en una primera posición de mando activa medios que evitan la impresión de los tipos pertinente al pulsar teclas de signos y en cambio, hacen que, al pulsar teclas, el carro o el porta-tipos retroceda con media velocidad, realizando sólo a cada segundo accionamiento de cualquier tecla de signo o de la tecla en vació un paso o espacio de escritura hacia atrás, y cuyo interruptor de funciones hace posible, en una segunda posición e mando, el accionamiento normal de la máquina de escribir.
