Abstract

Mechanical doll, characterized in that it is provided with a device, housed between the constituent parts of its thoracic cage, and constituted by two crankshaft arrangements directed horizontally and vertically in a respective way and joined together properly to allow their simultaneous rotation; the extreme axes of the first of which emerge to the outside by the sides of the thorax, and are conveniently layered, constituting the internal structure of the upper extremities of the doll; while the end axes of the vertically directed crankshaft arrangement are extended to join, respectively, to their heads and abdomen, the last of which is constituted by an independent piece not attached to the thorax, being the horizontal crankshaft of a gear wheel that engages with a screw with which it constitutes a conventional reduction system; whose worm is fixed to the underside of the disk-holder plate of a suitable conventional phonograph, whose plate is connected in the form of a pulley by means of the tension cable corresponding to the output shaft of an electric micromotor fed by the pertinent batteries, and whose support part of the amplifying membrane, is attached to the structure of the device by one of its ends by means of a recovery spring and by the other, by any suitable means that allows its movement in relation to the hypothetical axis or non-union, being provided with a lower protruding stem that is intermittently attacked by a cam integral and eccentrically attached to the central bar of the horizontal crankshaft constituents in the rotation movement thereof, which gives rise to the tilting movement of said support piece, which will press on the pickup arm to result in the reproduction of the recording of the perti disc, until the lifting of said piece results in the release of said arm, which will also be raised, and therefore being kept separate disc and reproductive needle, by virtue of its attachment to the structure of the device by means of a second spring of recovery, until again the support part of the amplifying membrane descends to press again on said arm; with all that, by knocking the doll on a surface and supporting his back on it and start the device by operating a conventional switch, will get the movements of the doll's head and abdomen, to both sides, describing separate arcs approximately semicircular, and the rotation of its arms around a horizontal axis, while the intermittent operation of the phonographic device and therefore, alternate periods of reproduction of the recording of the disc with others of silence.
