Abstract

1,265,023. Cylinder locks. WARTSILA A.B., OY. 23 May, 1969 [25 May, 1968], No. 26415/ 69. Heading E2A. In a cylinder lock mechanism of the kind in which a locking bar 13 is movable into and out of a locking position in which it is located between peripheral edges of locking discs 12 and a cylinder housing 10 and in which a key 14 for turning the discs is provided with combination surfaces determining the turning angle of the discs when the key is turned in one direction and with a returning surface for turning back the discs then the key is turned in the other direction the lock is provided with two different keys of which the combination surfaces compared with each other, and the returning surfaces compared with each other, work in opposite turning directions and the combination surfaces on the keys are made so that either one of the keys from its own starting position and its own turning direction is able to turn the locking discs to a cylinder releasing position. As shown, the discs 12 are provided with a projection 15, which when the key 14, Figs. 3 and 5, is turned through 90 degrees from the position shown, to a releasing position, moves the disc shown, in an opening 19 of the cylinder 11, through an angle b equal to 90-a degrees to align a recess 16 in that disc with the bar 13, the angle a being one fifth of a right angle and defining a combination value 1 for the disc 12. If the disc 12 occupies a position in which the projection 15 and recess 16 occupy the positions 15' and 16' respectively, the disc may be moved to the releasing position by the second key, (Figs. 4 and 6, not shown) in which the angle a defines a combination value 4. The two outermost discs of the lock are each provided with two recesses 16 by means of which the keys lift the bar 13.
