Abstract

Improvements in the construction of locks, characterized by the fact that the lock comprises a body containing two revolving cylindrical cylinders aligned in opposition and separated by a similarly rotating ring, obtained in sintered iron, provided with a driving tooth for driving of the latch of the lock, being coupled in the back of each bowler, in longitudinal grooves to the effect, a slide obtained in die-cut sheet, suitable for its penetration into the said ring on the corresponding side, for which that presents the appropriate lace, one of whose slides is pushed by means of springs that tend to separate it from the cylinder to insert it in the ring, determining the coupling between the cylinder and the ring in the stable position of the assembly, so that the opening of the lock is achieved by simple turn of the key applied by the bowler in question, while, when said key is applied by the other cylinder, it needs to press a certain pressure so that the corresponding slide pushes the remaining one to dislodge it from the ring and penetrate itself in it, in which circumstance the turning of the key for operation is feasible of the driving tooth, after which the initial position is automatically restored when the key is retracted under the reaction of the springs of the opposing slide.
