Abstract

Combined toy ratchet mechanism of the type comprising a micromotor related to a reducing device and a pneumatic turbine, characterized in that the secondary shaft corresponding to the reducer has a pinion of sufficient amplitude, in which two wheels of constant rotation are constantly engaged. Equal diameter and different number of teeth, in such a way that one rotates more slowly than the other, being both mounted on a third axis, one of whose wheels is fixed on said axis and has two arched slots of different amplitude, while the second has the possibility of axial displacement on the same axis, being requested a. Take contact with the first by virtue of a spring wound on the shaft; said second wheel presenting an axial tab capable of being inserted into the slots of the first to determine; in the lowest position interfere, by means of the tongue, in the field of position of a lever, perpendicular to the axis of the wheels, to which it forces an intermittent tilting movement by, which its flexible free end hits on a bell, being recoverable by the action of a spring; in the intermediate position, caused by the partial penetration of the tongue in the small groove, which produces an intermittent axial movement in the displaceable wheel, acts on an angular lever, raising or lowering it by the action of a spring, whose upper end opens or closes, respectively, an air outlet hole of the pneumatic turbine, producing an intermittent whistle; finally, in the highest position, in which the tongue slides on the surface of the lower wheel, the gear of the upper wheel is produced with a pinion which is integral with a plate equipped with cams acting on another angular lever that strikes intermittently on the chassis of the mechanism, simulating a rattle.
