摘要

Automatic phonograph perfected for the selective reproduction of recordings of two entrances, characterized in that it is equipped with a counterweight that joins it eccentrically by means of a vertical axis, around which its movement is feasible along a hypothetical horizontal arc determined by two conveniently located stops; whose counterweight is fixed below one of the ends of a rod located in a straight guide made to the effect below the needle-holder arm and along which it is possible to move, always within the horizontal plane in which it is located, in virtue of the existence of a stop shaped above said guide to prevent the rod from leaving it; the opposite end of whose rod is elbowed upper and vertically, said elbow being located previously to the initial limit position of the needle-holder arm determined by the convenient fixed stop, in which the picking needle impinges on the groove corresponding to one of the two recordings that the disc is equipped, which will be reproduced when the device is started up, keeping it in a horizontal position; while the change to the vertical position will lead to the movement of the counterweight and, therefore, to that of the rod, whose elbow will drag the arm to a second position in which the needle will strike with the groove corresponding to the second of the recordings of that the disc is gifted.
