hinged pressure rails are moved.

Addendum to patent 219349.

Patented in the German Empire on November 12, 1913. Longest duration: December 16, 1923.

The invention relates to a special arrangement of the moving members for the punching knife on devices for punching out porcelain tableware according to additional patent 219349. According to this patent, the punching knives lying next to one another are individually or also two of them set in motion by pressure rails, all of which are hinged to a sliding sleeve and attack them in one plane.

In the case of very small devices with a large number of punching knives, the rails can still be easily connected to the knives, but the sliding sleeve allows the connection the relatively many pressure rails in the previous way not to, because you start with the training of the sliding sleeve a small diameter is bound to allow proper movement the punching knife to ensure the required inclined position of the rails.

In order to eliminate this disadvantage, pressure rails are now according to the invention of different lengths hinged to the punching knives lying next to one another and in one on top of the other Levels connected to the sliding sleeve.

On the one hand, this ensures a convenient connection for a large number of pressure rails to the sliding sleeve and 35

on the other hand, the advantage achieved that the rails articulated at higher points the associated punching knives with a certain lead over the lower hinged ones Move punching knives, which has a beneficial effect on the operation of the device is divided as the force required for punching.

The subject of the invention is shown in the drawing in

Fig. Ι in side view with partial section and in

Fig. 2 is shown partially in a bottom view in an exemplary embodiment.

According to this embodiment, the punching knives α provided with guide pieces -p are guided on the one hand in the lower disk c and on the other hand in the cup-like part b covered by the hood e .

The knives are connected by pressure rails f, f ¹ to a sliding sleeve d which carries the pressure rods h, h ^1.

The pressure rails f, f ¹ have different lengths and accordingly engage two superimposed rims g, g ^{1 of} the sliding sleeve d , in such a way that between two rails of the same length acting on the lower rim there is a rail of a different length which is attached to the upper wreath is hinged.

It goes without saying that the rails can also be dimensioned in such a way that their connections to the sliding sleeve are more or less staggered.

Claims (2)

Patent Claims: i. Device for punching out openings in porcelain tableware or the like, in which the knives according to the additional patent 219349 are moved by pressure rails articulated to a sliding sleeve, characterized in that the pressure rails articulated to the adjacent punching knives (a) are of different lengths and are one above the other Attack planes on the sliding sleeve moved by a printing unit. 2. Apparatus according to claim i, characterized by the use of two rows of pressure rails (/ ", f ¹ ) of different lengths, which act on two superposed rings (g, g ¹ ) of the sliding sleeve (d) , wherein they are mounted in such a way that In each case between two rails (f) of the same length engaging the lower rim (g) there is a rail (f ¹ ) of greater length which is hinged to the upper rim (g ¹ ). 1 sheet of drawings.
