摘要

Improvements related to the alphabetical selection in the register and archive accounting machines and which specifically concern those machines that automatically select certain folder or similar tab among those contained in a deposit or file through the successive introduction of the tongues of electromagnets and whose tabs they act on the tabs or projections that in a variable number and/or situation have each of the objects to be selected, characterized essentially because each of the keys of the typewriter or the alphabetical keyboard of said machines have an extension that when the key is operated, it acts on a device designed to act on certain and different electrical contacts between different circuits as well as on a variable number of these circuits.
