there is the advantage that with simple Mitfein 30 Dei main frame 10, which, as already mentioned. a robust, but safe and accurate working the inner recess 12, contains the adjustment device is created, which not only arranged outer wall parts that of these allows that a seat or support surface 36 for the adjustment desired next in an easy and simple manner Processing position on the device 1 arises on the work table. This setting template by means of the optical visor support surface 36 is detected and seen inside the same by the device, but a shoulder 34 is attached in such a way that the contact also ensures that a displacement of the setting device 1 with the cover plate 152 of the setting device with the help of a is limited to its outer walls.

As can be seen in particular from FIGS. 3 and 4, the lowering mechanism 50 has two identical arrangements, the adjusting device 1 contains a lifting device and a lowering device 50 and a viewing device 10 which are attached to opposite sides of the frame. These same arrangements are device 100. The adjustment device 1 is also operatively connected to one another. They are connected to common locking device 150 . This is actuated in sam by a shaft 74, the two Anciner cover plate 152 attached, which is commonly assigned 55 orders and which is designed in such a way that it is equipped with actuating handles 76 at the working table 152 'of the in the figure is not shown.

Troughs 14 generally have an identical lobe. A leg-like formed part 58 is on

running essentially perpendicular to these, firmly attached. The leg-like parts 58 are provided with feet 6 for the purpose of easier movement of the dark device 1, which reveal a ball roller, a roller or similar elements. By means of these foot parts 60, the Hinslell device 1 moves over the surface of the cover plate 152 on the work table 152 'with a relatively large amount. ^! .i | ', move with little effort.

It can also be seen from the drawings that the overlapping z.ungenaitigcn parts 52, 1 and 54/1 are semicircular on their outside and that they are held together by a common pivot pin 62. The pivot pin 62 enables a relative rotational movement between the main support parts 52 and 54. The triple pin 62 is rotatably mounted in a clamping strip 64 and protrudes into the tongue-like parts 52, 1 and 54Λ through slots which cannot be seen in the figures. From the kind according to which the main styles 52 and 54 pivot in opposite directions. it can be seen that the slot in the tongue-like parts 52 A and 54/1 must be slightly larger than the diameter of the pivot pin 62. The terminal strip 64 is used to hold a lind of a / ngkabel (xler band 68 The pulling cable or band 68 is preferably made of steel or some other material with considerable strength. Its other end is fastened to a lifting drum 72 by means of 3-1 screws 70. This lifting drum 72 is \ on the shaft 74. which, as already mentioned, rises outwards from the frame 10 at opposite points and is provided with locking grips 76. So that the pulling cable or hand 68 is now on the lapping tongue-like parts of the main support parts 52 and 54 exert an upwardly directed lifting force which runs essentially perpendicularly with respect to the work table 152 ', a guide wood 78 is attached in the frame 10.

If you want to move the adjustment device 1. all the operator has to do is turn the actuation handles 76. This exerts a force on the inferior portions of the main support members 52 and 54 of the raising and lowering mechanism 50 which move them counterclockwise or clockwise as shown in FIG. 3 can be seen, pivot and exercise a Huhw'rkung.

As already mentioned, if the operator wants to change the position of the adjustment device 1, he can look at the template 24 through the adjustment window 18 and via the reflective surfaces 101 and 104. As can be seen in particular from FIG. 4, the reflective pool 102 is firmly attached to a holding shaft 106 pivotably mounted in the frame 10. This Hallcrungswcllc 106 protrudes outward from the frame 10. There it is provided with an actuating handle 107, as can be seen from FIG. 1. By adjusting the operating grille 107 by the operator, the reflective surface 102 is pivoted and adjusted in such a way that different lines of sight !! fall from the observer across the observation window 18 and onto the reflective surface 102. The reflective surface 104 is arranged in such a fixed and rotatable manner that the line of sight is reflected from the reflective surface 102 downwards directly onto the template 24 Guide over the Fin setting template 24 and so that it can ablastcn. The reflective surface 104 is firmly attached to an I.agerhloek 108 by means of fastening screws 110 or the like. The bearing block 108 contains two bore holes that are directed to rotate it, one of which is attached in such a way that it receives a mounting shaft 112, while the Another bore receives a find of an actuating rod 113, which protrudes outward through the frame 10 and carries cincji OtilTIM on the outer find. The actuating rod 11.1 is against a relative movement to the bearing block 108 by means of a locking screw 114 od. Ii. secured. In order to enable the reflective surface KU to be adjusted horizontally, the bearing block 108 is slidably mounted on the support shaft 112. Rotational movement is desired, the reflective surface 104 Lelai. · To the llalterungsschafl 112, w-.i *> this preferably has a square or rectangular förmigc Oue'rschnittsfläche.
