ABSTRACT OF THE DISCLOSURE A cylinder lock whose stator has a longitudinal groove and whose rotary cylinder has a key receiving slit, two series of seat- ings and two orthogonal slits; a series of sliders pushed by springs is inserted, with mobility in two directions, into the first series of seatings of the cylinder and cooperates with a key, and each slider is provided with projections and with a member for 51 i ding engagement; a series of tumblers is slidingly inserted into the second series of seatings of the cylinder, and each tumbler is provided with recesses turned towards the sliders and with at least one recess at the opposite side; a stop bar pushed by springs is inserted into an orthogonal slit and is provided with projections turned towards the tumblers and with a continuous projection suit- able for being inserted into the groove of the stator; and a trans- lation bar pushed by springs is inserted into the other orthogonal slit of the cylinder, engages the members for sliding engagement of the sliders and is provided with a continuous projection suitable for being inserted into the groove of the stator; the parts are co- ordinated in such a manner that the stop bar immobilizes the tumb- lers until its continuous projection penetrates into the groove of the stator, and that the sliders engage the tumblers until the con- tinuous projection of the translation bar penetrates into the groo- ve of the stator, thus giving rise to a condition in which the key can be replaced by a different key.
