Abstract

1,076,840. Telephone dials. SOCIETA' ITALIANA TELECOMUNICAZIONI SIEMENS S.p.A. Dec. 28, 1964, No. 52581/64. Heading H4K. In a telephone dialling mechanism in which numbered holes are spaced equally around the whole circumference of the dial plate due to its reduced diameter, the stop member is allowed limited movement so as to provide the rotation of the dial normally provided for by the free space on the dial. The stop member 20 is located underneath the dial plate 10 and is rotated about the spindle towards a stop position upon rotation of the dial by a depressed one of the pins 19, each one of which is associated with a numbered hole. The stop member is returned to its initial position upon release of the dial.
