CLASS 68: Locksmith.

The movement of the lock mechanism happens as follows:

When the door is not closed, the arm e sitting on the Nufs f moves between the two pins s and t and pulls the hook lever c , which is rotatably attached to it in d, and which engages with its hook on the latch shaft a ¹ and so the latch α emotional. The hook lever c retains its horizontal position when the trigger is moved through the wire rod h, which makes it impossible for the hook lever to slide off the latch shaft. For the unhindered movement of the latch head, which is thicker on both sides by the thickness of the lock plate, the lock plates are correspondingly bulged at this point. The trap is so constrained that it can be pulled out by removing the screw b and turned around in order to use the lock as a left, possibly right, one. When the lock is closed, the tumblers m ¹ m ² m ³ , which can be rotated in η, are lifted by the key, whereby the bolt k, which can be rotated in I, is released by evading the tumbler arms n> at χ .

When the bolt k is moved further, the lever q , which can be rotated in ν , locks the trap by means of the wire rod ρ. At the same time, by turning the bolt k, the hook lever c is lifted by means of the wire rod h , whereby free movement is established for the pusher mechanism, u is a pin to support the cover plate and i is a screw to hold it in place.

Claims (2)

Patent claims: At a Thürschlof: 1. The arrangement of the trap serving as a bolt , which is determined by the lever q and at the same time pressed into the bolt hole. 2. The arrangement of the hook lever c, which can be rotated about d , by lifting it from the latch shaft a ^l, the handle is allowed to move freely when the door is closed, and to prevent damage to the lock when attempting to open it by unauthorized hands.
