Robert Ingersoll & Bros., New York – 1910

Index typewriter with double switching for lower case, upper case and characters.
The pointer handle is set to the desired character, which causes you to rotate the type wheel located at the bottom of the index head. By pressing down the entire index head, the sign is printed on the paper and the cart is pushed one Position further.
The Switch takes place by raising the pointer and twisting the middle part, the pointer latches into one of the three positions between the nickel-plated pins. The Darling writes a total of 78 characters through this double switch, contrary to other literature references.

In addition to this normal version mounted on a base plate, there is also a mysterious specimen of the Darling, which has neither carriage nor base plate. It is referred to by the owner as a "Pocket model".
