WOLF BASCH and MAX BASCH in BERLIN. Rack lock for safes.

Patented in the German Empire on July 3, 1894.

The present invention forms a rack lock for safes, which one is intended to cause the safe to be locked in such a way that it prevents any unauthorized intervention Hand resists. While in the earlier constructions the safe was without Difficulty could be forced apart by means of screws on the side of the door, this is at the new invention made impossible. The row lock consists of several hooks and Bars which, when the cabinet door are closed, are placed on top of one another so that they lock Breaking open the door cannot take place. The lock can be through a lock, z. B. a specially prepared collective locker can be closed and opened.

The accompanying drawings give an illustration of such a locking device, and indeed gives:

Fig. Ι the view of the safe door,

Fig. Ι a the view of a hook Z ₈ ,

Fig. 2 shows the outline of the door along the line IH-IV of Fig. 1,

Fig. 3 shows the section along the line I-II of Fig. I.

The door of the safe is inserted into the front frame α and fastened in the capitals ft. A frame f is attached to the front frame and is provided with holes on all four sides through which the hooks i and Z ₁ attached to the door pass when the door is closed.

The inner box e also has holes on the two side walls of the upper and lower wall through which the bolts attached to the door

The hooks Z ₈ differ from the hooks z \

The bolt Z is rotated by a lever m rotatable on the pin M ₁ when the door is closed by one of the bolt heads Ar ₈ and takes the bolt Z with it through the projection Z _{1, the bolt heads Z 8} in the above-mentioned manner between the Insert hook z ₈ and bar f ₁ .

Allow bolt heads. The movement
Nufs η is exceeded by a mandrel on a handle H provided on the outside of the door (Fig. 2):

The mode of operation of the locking device is as follows:

If the lock S is opened, the bolt heads q can enter their slots. If you now turn the handle H, the bolts will come out of the corresponding hooks and holes due to the effect of the lever transmission described above and thus allow the door to be opened.

If you want to close the cabinet, you turn the handle H in the opposite direction, whereby the bolt heads qq come out of their slots and the bolts k enter the hooks i , thus opening the door is impossible.

As mentioned in the introduction, the arrangement of the bolts and hooks is special The purpose is that the frame can be blown up by means of a screw device, such as that used by burglars usually applied becomes impossible. The hooks provided on the door hold the frame of the door together, so. that bending apart cannot take place.

Claims (1)

Patent claim: Bolt lock for safes, characterized by hooks attached to the door opposite the bolt heads (i _s i _e ij, which pass through holes in the door frame when the door is closed and pick up the heads of the same when the bolt is pushed forward (k _s k _& k ₇ ), so that a piece of frame or a rod ff J connected to it is enclosed by the door, the hook and the bolt, while on the hinge side of the door the bolt heads / ₈ on the bolt / 8 are between the hooks z ₈ and the bar J ₁ to prevent the frame from unscrewing sideways as well as unscrewing the door forwards. 1 sheet of drawings.
