Abstract

Simplified gramophone, of the type in which the movement of rotation of the disc is determined by direct manual action on it, and in which the vibration amplifier is constituted by a sheet to which it is fixed, suitably projecting from its edge the corresponding reproductive needle, characterized by consisting essentially of a single die-cut piece of semi-rigid laminar material, which, by means of two corresponding rectilinear lines of bending, is divided into three flat areas, each of which is ready to be refuted with respect to the above, the first of whose zones constitutes the base of the assembly, the corresponding disc is fixed, which is free to rotate, and is related to the second zone by means of at least one elastic brace, which is locked in a corresponding pair of taped lugs, for this purpose provided in these areas, constantly pushing the second ar fight over the first one; while the third referred zone comprises the reproducing needle, which protrudes conveniently from the free edge thereof, being able to rest on the grooves of the corresponding disc; all in such a way that the whole can adopt a retracted position -of storage and transport- in which the third area referred to is refuted on the second and both on the first, the whole occupying a minimum volume and the needle and the disk being duly protected , or a working position in which the third zone is located in a plane approximately orthogonal to that of the first, the water resting on the grooves of the disc with a certain pressure, determined by the expressed elastic brace.
