PATENT OFFICE.

In most steelworks, especially the Bessemer plants set up for large-scale production, if the need arises, besides the existing Giefs device, the usual one in a hydraulic crane carrying the ladle, there is still a second to be put in place, First, to be able to set up more coquilling and casting molds, and second, the casting site to remove more from the converters.

For this purpose, the ladle filled by emptying a converter must be removed from the hydraulic crane to be placed on another transport device, through which the same can be moved floating over the coquilles or molds, which, in rows orderly, stand in a pit, trench or on the bottom of a hut. This is used up to now mostly an iron wagon, on the top of which the ladle is placed with the bottom is that the foundry hole in it, standing in a recess in the plate, remains free at the bottom. 1. In order to be able to bring the wagon into the area of the gief crane, the track has to be led into the area covered by this and so it goes part of it is lost for the setting up of coquilles, and the track is also for them Movement of the crane obstructive; 2. after placing the pan on the trolley is the same can no longer be rotated in the pin and can therefore be returned to the crane when the need to tilt occurs.

To i. The problem referred to under 1. is avoided by the central overhead traveling crane shown in FIGS. 1, 2 and 3. Its pivot point is at A, while the load is supported on rail B by means of wheels C and D and the associated bearing E. The ladle carriage F rolls on the lower, inner flanges of the I-beams G and is moved either by a hydraulic device H or a manual winch to bring the Giefsloch over the middle of the Coquillen K standing in several rows in the Giefsgraben.

To move the overhead crane in an arc-shaped direction, either a hydraulically moved rack, which engages a gear segment attached to the sleeve A , or a hand winch with a crank and gear transmission, as shown at L , through which one of the running wheels C or D rotates will.

To 2. To eliminate the second disadvantage of the previous facilities, the Giefspfanne A, Fig. 4, 5 and 6, is stored on a carriage B , on which a complete tilting device with worm gear C, countershaft and handwheel, as well as a winch D for Moving the carriage is attached. While a converter is being emptied into the ladle, this stands on the arms E of the central crane and is placed on those F of the gief crane for casting the steel into the coquilles, which is otherwise shown as in Fig. 1, 2 and 3 or with a hydraulic lifting device, as known, is set up.

So there are the arms of the central crane and then those of the gief crane as a track serve and lowering the car from one to the other by lowering it

of the former or lifting of the latter takes place, the wheels G receive double the running width, and the two different track widths formed thereby correspond to the distances between the arms of the central crane respectively. of the gief crane. The same could also be achieved by adding two sets of wheels with different gauges, but this would not be so simple.

In the same way, the (Gief) ladle car can be set down on a stationary one Tracks are made.

Claims (2)

Patent-to sayings: 1. The overhead crane rotatable about the vertical axis A , Fig. Ι to 3, with support rollers CD and in connection with the device H for moving the ladle carriage. 2. The ladle car shown in Fig. 4 to 6 with wheels, which two gauges form, together with a device for setting it down from one track width to the other. For this purpose I sheet drawings.
