 vices, and a selector-one of which elements has a feed movement controlled by the signal-components, and means for imparting shift movement to one of said complementary elements relatively to the other for bringing different components of each group into action.

22. A receiving telegraph instrument comprising a plurality of character-indicating devices and also a translating receiver controlling said devices selectively in accordance with the combinations of receiver-influencing signals representing their respective code characters, said receiver embodying the following complementary elements, viz.-groups of differential character-selecting components which groups correspond in number to the maximum number of signal components of any of the code characters representing said character-indicating devices, and a selector-one of which elements has a step-by-step feed movement controlled by the signal components, and means for imparting a shift movement to one of said complementary elements relatively to the other for bringing different components of each group into action.

23. A receiving telegraph instrument comprising a plurality of character-indicating devices and also a translating receiver controlling said devices selectively in accordance with the combinations of receiver-influencing signals representing their respective code characters, said receiver embodying the following complementary elements, viz.:-groups of differential character-selecting components which groups correspond in number to the maximum number of signal components of any of the code characters representing said character-indicating devices and have their differential components separated by like spaces in all groups, and a selector-one of which elements has a step-by-step feed movement controlled by the signal components, and means for imparting a shift movement to one of said complementary elements for bringing different components of each group into action.

24. A receiving telegraph instrument comprising a plurality of character-indicating devices and also a translating receiver controlling said devices selectively in accordance with the combinations of receiver-influencing signals representing their respective code characters, said receiver embodying the following complementary elements, viz.-groups of which differential character-selecting components which groups correspond in number to the maximum number of signal components of any of the code characters representing said character-indicating devices and are equidistant from one another and have their components separated by like spaces, and a selector-one of which elements has a step-by-step feed movement controlled by the signal components, and means for imparting a shift movement to one of said complementary elements for bringing different components of each group into action.

25. A receiving telegraph instrument comprising a plurality of character-indicating devices and also a translating receiver controlling said devices selectively in accordance with the combinations of receiver-influencing signals representing their respective code characters, said receiver embodying the following complementary elements, viz.-groups of differential character-selecting components which groups correspond in number to the maximum number of signal components of any of the code characters representing said character-indicating devices, and a selector-one of which elements has a step-by-step feed movement controlled by the signal components, and means for shifting one of said complementary elements relatively to the other from a normal position to either of two other positions in either direction for bringing different components of each group into action.

26. A receiving telegraph instrument comprising a plurality of character-indicating devices and also a translating receiver controlling said devices selectively in accordance with the combinations of receiver-influencing signals representing their respective code characters, said receiver embodying the following complementary elements, viz.-groups of differential character-selecting components which groups correspond in number to the maximum number of signal components of any of the code characters representing said character indicating devices, and a selector-one of which elements has a step-by-step feed movement controlled by electrical signal components of different lengths, and means controlled only by the longer electrical signal components for imparting a shift movement to one of said complementary elements for bringing different components of each group into action.

27. A receiving telegraph instrument comprising a plurality of character-indicating devices and also a translating receiver controlling said devices selectively in accordance with the combinations of receiver-influencing signals representing their respective code characters, said receiver embodying the following complementary elements, viz.-groups of differential character-selecting components which groups correspond in number to the maximum number of signal components of any of the code characters representing said character-indicating devices, and a selector-one of which elements has a step-by-step feed movement controlled by closures of the circuit of different lengths,
