Ferdinand Weinlein in Mannheim. Security lock for cash registers and other containers.

Addendum to patent 344982.

Patented in the German Empire on June 23, 1920. Longest duration: August 8, 1934.

The invention relates to a security lock for cash registers or other containers according to the type of patent 344982 and thus represents a further training or improvement this clasp represents as now

an even greater security against unauthorized opening of the closure is achieved. While in the closures of the main patent rotatably seated on the lid Thumbs, which are under a firm neck 4es

Can grab the container, are brought into the locked position by direct action on them and out of this, in which positions they are secured by a locking disk that can be locked itself, the [locking thumbs according to the present invention are only indirectly through the action of a thumb -; menscheibe on them from the blocking position out \ rotatable. The thumb disc is turning! ίο bar and adjustable in height and can only have a rotating effect on the noses of the thumbs when it is in a raised position. The thumb disk can only be raised after turning a bolt aside, which in turn requires the corresponding setting of a rotatable disk that locks it, which in turn is held in the locked position by another bolt that must be released beforehand. In this way, a threefold security of the locking thumb and thus a complete security against opening of the lock by unauthorized persons is achieved.

The subject matter of the invention is illustrated in the drawing, for example.

Fig. Ι shows a vertical section through a cash register with the new safety lock! when it is closed; j

Fig. 2 is a section on line AB of Fig. 1;

Fig. 3 shows the lid seen from above; j Fig. 4 shows the same section as in [Fig. i, but the lock in the open position; i Fig. 5 is the corresponding horizontal section to Fig. 4; ^:

Fig. 6 to 10 are special representations. ! The cash register or other container a 'has, in turn, above a ring ^encircling: b and c border a liftable lid with a lug b C ₁ within the margin: engaging the container and so is secure. : Outside on the lid, on the inside! side are rotatably arranged thumb d , and <their axis of rotation is mounted so that it can not be determined from the outside of the lid. The thumb under the action of a suitable spring attached d _lr which tends always the same to rotate in the locking position. In the open position (Fig. 4 and 5), the same can be accessed by the outside with a button 0 .. provided locking pin ο (Fig. S and 6) \ keep overall which is guided from the top outside to the inside and under the action Helical spring O ₁ is standing, which always tries to move it outwards into the position shown in Fig. 6 ^a. The locking pin can engage the associated 0 Sperrdaumens d and so this in \ the rotated-back position to hold in a recess o ". Here, j becomes 0 !

and corresponding design of the wall of the recess o _{2 of} the bolt 0 held against the action of the spring O ₁ in the blocking position.

On each thumb there is a nose p on the side facing away from the actual locking end. With these noses, the thumbs Q _{1 of} a central thumb disk q can come into action. This disc q has two such thumbs q _± , which can act simultaneously on two opposing locking thumbs d . The disk q sits on a bolt q ₂ , which is guided through a hole in the cover and has a handle q _s at the outer end. The bolt q " has play in its bearing so that the disk q can be adjusted in the vertical direction, to the extent that it is out of engagement in its depth position (Fig. 1 and 7) with the lugs p of the locking thumb d.

The thumb disk q can be held in its depth position by a disk-shaped bolt r, which can be rotated from the outside using a button r _x (Fig. 7); the disk r stands above the inner surface of the thumb disk q. The locking disk r has a cutout r _{2 which} , after appropriate rotation, is adjacent to a circular part q "of the disk q (Fig. 9), so that the disk q can then be moved upwards, and then the thumbs (k with the noses p the bolt thumb d can work together (Fig. 4). The bolt r has concentrically with it and firmly connected to it a second, somewhat smaller disc r _s , which has a circular shape and a cutout r _{4 on one side} Concentric disk arranged with the central axis. This is seated on a bushing S ₁ , which surrounds the central bolt q ₂ , guided to the outside of the cover, provided there with a collar S ₂ and can be rotated around the bolt q ₂ by means of this Disk also has a section S ₃ , the radius of which corresponds to the radius of the disk r _3.

Finally, a bolt i belongs to the disk s , which grips through the cover with a pin and can be turned from the outside by means of a button t _t. The bolt t has a recess i ″, the radius of which corresponds to that of the disk s. Rotation of the bolt t is only possible ^T w hen the recess s _s j of the disc in its area is made.

The safety lock according to the invention is used in the following way: the thumbs d must be in their inner position in order to be able to put the cover on, ie they must be turned inward and fixed by the spring bolts 0.

After putting on the cover one only has to _{pull out these bolts on the buttons O 3} in the position of Fig. 6 ^a , so that they release the claws and these are rotated under the action of their tension spring outwards into the blocking position in which they are reach under the edge b of the container. After this has been done, you have to press down the thumb disk q on button q _3,

ίο turn the bolt r so that it rests on this disc (fig. 7) and prevents it from moving back; The bolt must be adjusted so that its cutout ^ comes to lie next to the disk s , which is possible because the cutout S _{3 of} the disk s is brought into the area of this bolt while the bolt r is turned (Fig. 10 ), so that the round part r _{s of} the locking disc r can rotate _{in the cutout J 3.} If this is done, the discs is rotated until its cut-s _a in the region of the opposite bolt t is (Fig. 8), and this is then, in turn, is rotated so that its circular part is engaged j in the segment of the disc and this thus establishes, so prevents further rotation. As a result, the entire locking system is triple locked. An opening can only take place by reversely starting with the reverse rotation of the bolt t and finally releasing the thumb disk q so that it can be moved into the area of the locking thumb noses p and the locking thumb d can be turned through it into the open position. For this purpose, the bolt t must be rotated in reverse order so that its section t ₂ meets the section s _{s of} the disk j. This releases this disk so that it can be rotated from the outside _{on its collar J 2.} The rotation takes place until the section J ₃ comes together with the section r _{4 of} the locking disk r ₃ , so that this is now also released and can be rotated. Its rotation takes place until its section j ' ₂ comes to lie opposite the circular part q _{2 of} the thumb disk q, which was previously blocked by the disk r , so that finally the thumb disk q is released in an intended manner and on the handle ^ ₈ can be pulled up in the manner shown in Fig. 1 and 4, so that it can act with its noses ^ ₁ on the noses p of the locking thumb d . For this purpose, one turns the thumb wheel q something on the handle q _a, whereby by means of both thumbs q _x same time the two opposite locking thumb rotated and moved from its locking position in the open position 6n. At the same moment you press the locking pins o on their buttons O ₃ , which hold the claws d in the open position after the thumb disk q has passed. Proceed in the same way with the other two locking thumbs d. The lid is then released and can be removed.

Of course, the buttons on the outside and the collar J _{2 of} the pane j must have appropriate signs or marks (Fig. 3), which allow the initiated to open the lock according to certain principles, but completely prevent it from being opened by unauthorized persons. As Fig. 3 shows, only the buttons can be seen on the top of the lid, and there is no indication of how and in which order they must be handled. So there is an absolute security with this closure.

Claims (1)

Patent claim: Safety closure for cash registers and other containers according to Patent 344 982 characterized in that the can be rotated from the locking position Greifensee below a neck of the container g ₀ the locking thumb (d) only through the intermediary of a rotatable and height-adjustable position thumb disk (q), which thumb washer only works in its raised position on the lugs (p) of the locking thumb and in which position it can only be brought after turning a bolt ir) , which in turn requires the corresponding setting of a rotatable, locking disk (j), which in turn for is usually held in the blocked position by a further bolt (t).
