Abstract

Improvements in the construction of revolving cylinder locks, characterized in that a lock is made up of a rotating cylinder fitted inside a fixed cylinder, covered, in turn, by a cylindrical envelope, so that the rotating cylinder has a notch longitudinal, diametrically, flanked on both sides by a series of housings suitable to contain initially identical locking pins and provided with a rib with pivot on the side of the notch, while the fixed cylinder has a series of holes as a continuation , on both sides, of the housings of the rotating cylinder, all this in such a way that on the corresponding key, there are on each side discretional path grooves such that, once the key is inserted in the notch of the rotating cylinder, they are applied to them , at different heights, according to the sinuosities of the grooves, the pivots d e the pins, whereby the ends of the latter emerge from the periphery of the rotating cylinder according to lengths of different magnitude, said ends being then cut off at the level of said periphery, which corresponds to the opening position of the lock once when the key is withdrawn, the pins descend by gravity until their pivots, acting as a stop, reach the bottom of the notch, with which the pins themselves introduce their lower end in the holes of the fixed cylinder, impeding the mobility of the rotating cylinder, giving rise to the closing position of the lock.
