709 aA7 / 1086

Lid BI is equipped, which in turn freely into the opening of the container B can be used (see. Fig. 3). The lid Bi is loaded by springs B2, which in turn ση a traverse C3 are attached, the ends of which are equipped with claws B4, which can come into engagement with toothed clay B5, which in turn are spring-loaded and pivotable to the side walls of the cooking container B, diametrically opposite each other, are hinged. With this arrangement it is possible to apply a suitable mechanical pressure to the ham to be cooked, which can be appropriately adjusted by the engagement of the claws B4 in the toothed engagement of the racks B5.

The stand A consists essentially of a support structure 10, which is equipped with feet 12 at the bottom, on which adjusting screws 14 are provided for specifying the height and / or the inclination of the stand A.

The pillars 16 of the supporting structure 10 have cantilever arms 18 between which a loading table 22 is held pivotably about a horizontal axis in pivot bearings 20, the inclination of which by means of locking elements 24, which can be displaced in arcuate slots in the cantilever arm 18, is adjustable, as can be seen in detail from the perspective view of FIG. evident.

The pillars 16 also carry a frame 26 which is arranged above the loading table 22. The two opposite side parts 28 of the frame 26 are on the side pillars 16 of the stand A. attached in their center. The transverse side parts 32 of the frame 26 are by means of guide elements 30 horizontally opposite the Pillars 16 can be moved.

709847/1086

Screw spindle arrangements 34, which via a flexible transmission 35 are coupled to each other, are with the two opposite longitudinal side parts 32 of the frame 26, which of the Guide elements 30 are slidably supported, in engagement to this Side parts 32 to be adjusted symmetrically with respect to the central part of the transverse side parts 28.

A screw spindle of the screw spindle arrangements 34 is used for this purpose provided with a handwheel 36, by means of which the mutual distance between the two longitudinal side parts 32 to the bottom is still increasing can be set for explanatory purposes.

These longitudinal side parts 32 of the frame 26 hold by means Pivot pin 33 clamping jaws 40, the shape of which is such that they can come into engagement with opposing outer walls of the cooking vessel B, which is held in the inverted position to free oscillation of the racks B5, which are hinged to this container B, to enable hen. In addition, these jaws 40 are such arranged and designed so that their engagement against the container B (regardless of the size of the currently inserted container B) is coaxial Alignment with respect to the axis of the support structure 10 ensures, at the same time it is ensured that the opening of the clamped container B is free and is oriented towards the loading table 22.

The upper cross member 42 of the supporting structure 10 has a piston-cylinder arrangement 44, the punch 46 of which is attached to a yoke 48, the in turn runs parallel to the plane of the frame 26. The movement this yoke 48 is guided by guide rods 50, which in turn on

709847/1086

upper cross member 42 of the support structure 10 are attached.

The middle part of the yoke 4o, d. H. the one opposite to the punch 46 Part, is attached to a threaded hole bracket 52, which is connected to a push rod that ends in a pusher 54, which in turn freely through an opening Bo in the bottom of the container B can enter, as can be seen in detail from FIGS. 2 to 4.

Furthermore, the yoke 48 carries two sliders 56 with downward facing Arms 60 and clamping screws 58.

The lower ends of these arms 60 are equipped with wedge jaws 62, which come into engagement with the racks B5 of the container B and can cause them to vibrate.

For this purpose, the arms 60 are fastened to the sliding pieces 56 by means of joints, which for example consist of pivot pins 64, and are subjected to a spring load (not shown in the drawing). The effect of this spring loading is stronger than the corresponding effect of the associated one of the racks B5 to the arms 60 to keep vertically and to allow them along zv slide outside of the cooking vessel B, on the other hand at the same time the pivotal movement and deflection movement of the respective rack B5 in the opposite direction.

The piston-cylinder arrangement 44 is in the of the respective user specific sequence fed or controlled, in particular with regard to the use of the device described in the course of a series of cooking

709847/1086

Ham cooking devices within a production line.

In order to prevent any operating errors, the control of the Piston-cylinder arrangement 44 are preferably made via two separate isolating switches, which must be operated by the operator with both hands at the same time, to avoid accidents or other operational errors.

The mode of operation and functioning of the one shown in the drawing Device results from the above description. The operator thus first sets the distance between the clamping jaws 40 with regard to the cooking container B to be handled. The container B itself is reversed, i.e. with the bottom up, on the frame 26 so that the clamping jaws 40 rest against the outer walls of the container B in the region of the container opening or in the vicinity thereof can.

The operator then controls the piston-cylinder arrangement 44 to move the jo ~ h 4Π and with it the structural parts connected to it downward, and this downward movement takes place in this way long until the wedge jaws 62 of the arms 60 come into engagement with the racks B5 of the cooking container B.

In this way, the racks B5 are moved outwardly to disengage from the claws B4 and release the lid Bi which, due to its weight, falls onto the loading table 22 where it is remains filed.

The downward movement of the yoke 48 continues, so that then the

7098A7 / 1086

Pusher 54 against the cooked ham C, which is arranged inside the cooking container B, and pushes it out of the container B. pushes out, whereupon he over the level of the loading table 22 is discharged in order to treat it otherwise, for example to wrap.

With further downward movement of the yoke 48, there are no disturbances do not expect, in particular, any collisions with the container B, since during this further downward movement the arms 60 can move apart freely spreading against the spring load.

When the limit of the downward movement is reached, the yoke 43 is together returned to the starting position with the structural parts attached to it, while the operator removes the emptied cooking container B from frame 26 and the above-described operation can be repeated.

When compared to the exemplary embodiment according to FIGS. 1 to 4 modified The exemplary embodiment according to FIG. 5 and FIG. 6 is based on the same construction principle; it is only the mechanical punch 46 by a replaced pneumatically operated arrangement, as can be seen in detail from the sectional view of FIG. 6 for a correspondingly modified one Printer 54a results.

In this modification, the cooking container B has in the center of its bottom at least one small opening B6 through which compressed air enters the container B can be introduced as detailed below.
