PATENT OFFICE

CLASS 68: Locksmith.

The present innovation is intended to be protected by patent claim 2 of the main patent Improve the device so that it opens for all doors - right or left, protruding more or less in front of the disguise - without changing individual parts used and can therefore be posted without the help of a locksmith. Simultaneously it should also be able to serve as a simple safety bar.

The parts described in Patent No. 41574 and occur in the description below, are denoted by the same letters.

The pintle H ° of the locking lever h receives prismatic shape in the bearing H and the bearing recess H ¹ incisions so DAF's account can be taken accordingly, by blofses pre- or resetting of the bolt in such and determining, by a screw of the cladding depth.

In order to lock the door without its actual lock, the locking lever has an eyelet h ² or a shoulder at its lower end, and accordingly the cladding or the second door leaf has a screw with a wing nut or a sash lock ³ . If h ^{B is placed} across, the movement of the locking lever upwards and therefore the opening of the door is impossible.

So that the bolt r can also be moved independently of the lever e , its shaft end facing the latter is drilled out and its foot r ² rotatably connected to e is arranged displaceably in the same by means of a pin r ^{3 (Fig. 2).}

When the door lock is opened with the lever e , the lock bolt is therefore withdrawn and the bolt r pressed into the locking lever by the foot r ^2. However, if you have bars r, z. B. to use it as a simple insurance bar, move and want to determine by means of its pin i in the notches P , this can be independent of the lever e respectively. the actual lock happen, which was only possible with the device specified in the main patent by unhooking the chain.

The lever e receives a number of holes e ¹ . Since these correspond to the pin of the rotary bolt e °, such, that e can be inserted with each of the holes on e °, the spiral spring ensures the rotation of e in a vertical plane, it is possible by addition of e, by connecting the chain or of the rear bolt head r ² can easily be adjusted accordingly for each special case with a suitable hole in the lever e.

The holes 1, 2 of the fastening ^{plate of e ° can be used to fasten a pin z 2} , so that e touches it when it is withdrawn and its movement is thereby limited.
