Abstract
A pocket calculating machine, characterized by being formed by a closed rectangular box of minimum thickness, which has an operative board in the central part of each of its faces. One of these boards corresponds to the additive operations and the other to the subtractive ones. Such boards are in turn formed by equal series, in magnitude and number, of grooves parallel to each other, all of which, except the respective first ones of the left, present in their upper part a curve, in the manner of a crook towards the left. Above these grooves, on the right hand, being placed in the extension of the spaces between slots, there is a series of holes or windows where the partial figures of the results obtained in the operations carried out through the corresponding slots appear. To this end, the latter, in their elongated and main part coincide with the left teeth of the cursors that support the numbers that appear through the holes of the results. The elbow and upper crook of each slot, serve to move the stylet, without lifting it, to another toothed located to the right of the cursor immediately before; and therefore act on this when the operation carried out implies a change of one unit in the immediate superior figure of the results.
