The object of the present invention is to provide an arrangement adapted to guide camping machines in front oftheftap hole;

to be stopped. The operation of guiding 5 tamping machinesinfront of the tap hole of furnaces is at the present timeusually done by. hand. In this casethe machine 1's susended from arotatably swinging arm. It

7 1S; evident that this work is not without danger 10 to the operator who must guide the machine until it is in position in'front of the tapping 7 groove,f and then bring it into the necessary gradient andin this position press it securely I against'the tap hole until the machine is se- ,curely held in front of the said tap hole by the V actuation of two holding-claws. Taking into consideration the extent of thedanger connected with'this work itis evident that-during its execution, the outflow of molten metal '01; moltenslag from the furnace cannot'be interrupted, anclxa-lso the difficulty experienced owing to the weight of the machine and the heat emitted by the molten metal or molten slag one cannot always succeed in 'bringing the machine intothe required posi overcome these disadvantages and also to pro-' vlde a machine which does not have to be guided in front of the tap hole by hand, and also to ensure the correct positioning of the machine in front of the tap hole. v i

lelogram is formed as follows :-The central point of the transversemember a is situated I most advantageously as if inthe rotating axis of the swinging arm and said' member is rigidly fixed so that its direction runs pref! erably parallel to'the tappingfgroove. Its direction can, howeverbe altered, for example, by a hand operated feed screw 10. Thetwo side members b and Q extend approximately to the endof the roekingshaft 2 and are linked to'or pivotally mounted at the ends The, opposite ends ofthe side members I) and 0 are also pivotally connected or linked to the tranverse member; d which is provided o with two symmetrically arranged guide slots.v

'lhe suspension arrangement of the tamping machine is suchthat, with the tamping machine itself as a fourth side forms a paral l elogram. 'One side of this parallelog gram is the transverse'member e, which is provided with a long central hole or slot and is pushed upon the one endof the rockingshaft by means of a bolt fastened to this, for example in the manner of a Gardan link or universal joint. The othertwo vertical members 7 and '9 extending from the ends of the transverse lmember e of the parallelogram pass perpen-,

dicularly through the guide slot of the transverse member d of the parallelogram. The tamping machine itself is suspended from the endsof the vertical members f and g.

i s members linked together to form a. parallelostrain of a parallel motion, a supporting struc- In Figures 2 and 3 the machine is shown in operative position by dotted lines.

The operation of the machine is as follows:The post 1 is swung about its axis 5 by an air operated cylinder 9. The transverse member (5 of the guide parallelogram 8 is moved parallel to the side a. By this means the transverse member cl of the guide parallelogram co-operates with the vertical memm bers 7" andg passing through its slots and carrying the tamping machine. The transverse member 6 by means of the slot or hole provided therein is pushed along the rocking shaft 2 and thus is able to rock and adapt itself to the required lateral displacement owing to the transverse member (Z changing its position. The gradient or dip of the tamping machine to the tap hole is attained, during the execution of these movements, by

means of the crank handle 5 moving in the "inclmed or curved guide slot 6 in the metal plate 7. The inclination of the guide slot is adjustable; that is, its gradient is depend ent upon the intended gradient of the tamp- When the swinging arm and with it the shaft 2, swings round, the crank handle5 of the crank shaft follows the course of the guide slot 6 in the plate 7, thus the rocking shaft 2 is rotated go according to the gradient of the slot and with it also the transverse member 6 and consequently the tamping machine linked to or pivoted at the lower end of the vertical rods f and .g dips.
