PATENT OFFICE.

The present invention is a device on embossing presses, which an untimely Moving out of two opposite work tables, which alternate under the press should be brought to prevent.

In such embossing presses, the back and forth movement of the two work tables caused by an intermediate piece with which the work tables are coupled and then can alternately be retracted into the press, but each of the both tables are made independent of the movement of the intermediate piece by disengaging them so that the finished goods are removed from the table and new ones are applied can.

The switching on or coupling of the tables with the intermediate piece has so far been done by means a handle when the table is in the outermost position on the exit. If the triggering of the table is missed at this point, then it drives in again the press one and it just depends on the attention and speed of the worker when accidents are avoided. But it requires a special skill of the worker because at the moment when he has to use both hands to work, he is with him somebody has to get the disengagement.

"These inconveniences are to be eliminated by arranging an adjustable stop on which, when engaged, the table's uncoupling device opens after the exit has been completed and disengages automatically. The adjustable one The stop can therefore be made at any time, even before the table is moved out is to be indented.

Fig. Ι gives the basic pattern of a double table with the adjustable stops in an embodiment,

Fig. 2 is a Aufrifs the press with another embodiment of the adjustable stop.

The reciprocating intermediate piece b can be connected to the two tables a ¹ and a ' ² by the rails c ¹ and c ² , depending on whether the coupling device is used on one side or on the other. In the illustrated embodiment, a locking rail d ¹ , which is arranged on the table a ^l , is used for coupling. By shifting this locking rail, driver lugs on the same are ^{engaged in the corresponding recesses in the rails c 1} and c ² and the table a ^{l is} coupled to the intermediate piece b. A handle g ¹ is used to engage this locking rail d ^l . It is now behind this handle on a special transverse ^{rail e 1 of} the machine frame, the stop f ^{l to be} adjustably attached so that it can be brought into the position shown or in the dotted position. When the stop f is in the dotted position, the handle g ¹ is also in the outermost extreme

When the table is in the driven position, do not touch the stop and the table a ¹ does not decouple. If, however, the uncoupling is to take place with the completed exit, the sliding stop f ^{l is first brought} into the position shown, the handle g ^l runs onto the stop and the table a ¹ is uncoupled by the locking rail d ¹ assuming the position shown.

In the 'embodiment of FIG. 2, the intermediate piece, which makes the reciprocating movement and has to take the tables a ¹ and a ² with it, is also denoted by b. The coupling of the tables with this intermediate piece should be done in a known manner by a pair of pawls h ¹ and h ² , which are pivoted on the side of the tables a ¹ and a ² and whose hook-shaped end with corresponding lugs z ¹ respectively. i ^{2 of} the intermediate piece b can be brought into engagement.

As adjustable stops on which the free ends of the pawls / 7 ¹ respectively. / z ² should accrue for the purpose of decoupling, a thumb k ^l respectively serves in the present embodiment. A: ² , which is on a wave I ¹ respectively. I ^{2 is} attached, which is stored below the tables on the machine frame. On this shaft is a two-armed lever m ¹ BEZW at the same time. m ² attached, which at its protruding from the machine free end by hand or by the foot lever means of the pull rod o ¹ respectively. o ² , which attacks at its other end, can be actuated.

In its closing position, this lever is held by the spring q ^l respectively. q ² , as well as by the counterweights on the foot lever n ¹ respectively. n ² . In this position of the double-armed lever m ^l respectively. m ² are the thumbs k ^l respectively. k ² in the position in which they respectively the disengagement of the pawls h ^l. h ² and thus the tables a ¹ respectively. a ² effect as soon as the exit of the tables is complete.

In the illustrated embodiment, the Schlufsstellung by a locking pin r ¹ respectively. r ² secured, which jumps under the action of a spring into a grain-like depression on the table gesture. This lock can be released automatically by pulling the lever vigorously.

If the automatic release device is to be put into operation, the lever m ^{1 is turned} either on the handle or by using the foot lever until the thumb k ² assumes the position shown by the thumb k ² ; then an automatic decoupling of the table would not occur.

To determine the lever ιη ^λ respectively. m ² and thus also of the thumb A " ¹ or k ² , a support lever s ¹ or s' ^{2 is arranged} under the handle of the lever m ¹ or m ² , which is inserted into such a handle by a handle t ¹ or t ² Position can be brought, as shown in s ² .

The process is now. as follows: As soon as the table a ^{1 has come} to the position shown on the left, the end of the ratchet lever h ^{1 runs} onto the thumb k ^l when the lever in ^{1 is} in its final position, as shown. The table a ¹ is thereby released from the intermediate piece b and remains in the position shown. The intermediate piece b then continues its movement with the other table.

But if the table is to work again, i.e. to be coupled with the intermediate piece b , it is only necessary to remove the handle end of the lever m ¹ or m ^{2 to} lift or on the foot lever w ¹ · respectively. n ² to step before the intermediate piece b has reached the table. As a result, the thumb k ¹ respectively. k ² depressed, the ratchet lever swings by its own weight into a horizontal position and automatically coupled with the nose ζ ¹ respectively. i ^{2 of} the intermediate piece b. If the handle end of the lever m ^{l is released} again, the lever returns to its original position under the action of the spring q ¹ and the table disengages itself automatically on its next exit.

If be to be produced with der.Maschine work in which a triggering of the tables is not necessary, and the same back for a while without interruption and can be brought here, so must, ensure the lever m ^l BEZW DAF. m ² respectively by support lever s ^1. s ² up and thus the thumb k ¹ respectively. k ^{2 is held} down, as shown on the right-hand side of the figure. With the lever in this position, the table will no longer be able to be automatically disengaged. If the table is then to be automatically triggered again, the handle t ^l respectively. if ^{2 of} the support lever is thrown and the automatic release comes into effect again.
