Abstract: A mechanism for machining an object, such as a key blank, to a desired shape at a plurality of successive positions in an axial direction of the object, includes a holder for the object. The holder is axially movable by means of a transfer mechanism with a rotatable shaft. There is a feeder member connected to the rotatable shaft and cooperating with a clutch device axially stationary relatively to the holder. Cooperating guiding surfaces are arranged to transmit to the holder an axial movement during a limited turning of the rotatable shaft. This turning is only a small portion of a full turn of the rotatable shaft. The machining of the object takes place as a continuous guided operation during such a turning of the rotatable shaft which is separate from the turning thereof causing the holder to move axially.

Abstract: A disc cylinder lock comprising a turnable cylinder enclosing a plurality of locking discs, turnable by the key of the lock, and between adjacent locking discs, intermediate discs. The intermediate discs are radially larger than the locking discs and are provided on one side with an axially extending edge portion defining a cup-formed space on one side of the intermediate disc, the opposite side of the disc being its bottom side. In the lock, the axially extending edge portion contacts the bottom side of an adjacent intermediate disc, so that the last mentioned bottom side forms a cover on the cup-formed space, thereby providing a substantially closed space for each locking disc, located between two adjacent intermediate discs. In this space the locking disc can move without being subject to axial load.
