UNIVERSAL ROLLING-TRAIN.

SPECIFICATION forming part of Letters Patent No. 399,726, dated March 19, 1889. Application filed January 7, 1889. Serial No. 295,606. (No model.)

To coZZ whom it may concern.-

Be it known that I, WILHELM BANSEN, a subject of the King of Prussia, German Emperor, and a resident of Kattowitz, Upper Silesia, in the State of Prussia, German Empire, have invented certain new and useful Improvements in Universal Rollin gTrains for Roundand Square Iron, of which the following is a full and clear description.

My invention relates to improvements in universal rolling-trains for rolling round and square iron; and it consists in placing a number of ordinary universal rolls one behind the other, so that round or square bar-iron may be rolled from the slab in one operation at a great saving as compared. with the old in ethod.

In order to make my invention more clear, I refer to the accompanying drawings, in which similar letters denote similar parts throughout the different figures.

Figure 1 is a top view of my improved universal rolling-train. Fig. 2 is a longitudinal section of the same. Fig. 3 is a vertical crosssection through the line A B, Fig. 2. Fig. 4c is a sectional view, on a larger scale, of the guides between each set of rolls. Fig. 5 is a crosssection through the line S, Fig. 4. Fig. 6 is a horizontal section. Fig. 7 is an end elevation of the driving-gear. Fig. 8 is a vertical section through the line E y, Fig. 7. Fig. 9 is a view of the different stages through which round iron passes in passing through my improved universal rolling-train. Fig. 10 is a view of the different stages through which square iron passes in passing through my improved universal rolling-train. Figs. 11 and 12 show the relative position of the vertical and horizontal rolls.

In the manufacture of small bar-iron namely, that under one and one-half inch a large number of skilled hands are required, as each bar has to be conveyed by hand from one roll to the next smaller and entered into the matrix in the smaller rolls, and held in position by the hand during the operation of reducing but in my improved universal rolls this manual labor is dispensed with, as the rod isheld in the proper position by the guides which are placed before each pair of rolls. Consequently it is clear that by this process much valuable time is saved and fewer workmen are required for the same work.

In my process the rough bar is led into the first pair of rolls by the workmen, and from this conducted to the next pairs of rolls automatically, where the complete process of rolling is gone through. In order to guide the bar from one pair of rolls to the next wlthout the aid of manual labor, there are guides fitted, through which the iron rod passes, and before every pair of rolls, with the exception of the first pair, there is a pair of vertical revolving plain rolls, which reduce the section of the bar before it enters the horizontal rolls.

The rolls A A, which have the largest grooves, are placed first in the train, Flgs. l and 2, and then the second, third, and fourth pair, in the order of the size of their grooves. Between each pair of rolls is a guide fitted, Figs. 4:, 5, and 6, which guides the rods from one roll to the next. The guide consists of the V-blocks s s, which are held firmly in their position on the face-plates The blocks 8 s are covered on the top by the hinged cover, which can be lifted by the rod which is being rolled, when the front roll dellvers more than the following roll can draw in, Flg. 4:. Just in front of the second, third, and fourth pair of horizontal rolls are placed the vertical fiatteningrolls B B B B B B These vertical flattening-rolls are so arranged that they fit into the guides and compress the bar of iron si'dewise as it passes through, Figs. 9 and 10.

The vertical rolls and the guides to w, which are placed close in front of the horizontal rolls, prevent the rod from turning, which is of great importance in rolling bar-iron.

The speed of the rolls A A A AB B, &c., is so regulated to each other according to the size of the different grooves that the following roll always takes the iron from the preceding one, and they are driven by the cogwheels Z) 19' b.

The plain vertical rolls B B B B 13 13 are driven from the cones O G G O C O. The cones C C drive the shafts c e 6 to which are fitted the conical wheels cl d d d d (1 These wheels gear into conical wheels d d d d d d on the shafts of the vertical rolls.

If each pair of horizontal grooved rolls A A A A &c., has a speed of twenty-five per cent. more than that of the foregoing pair,

tween each pair of rolls, the workman knows that the grooves in the rolls are set right and no injurious strain is brought to bear on the rod being rolled;

The vertical rolls B B to B B are set in the following manner, both when rolling round and square iron: Two screws, f f ,are fitted in the frame-work of the rolls, Fig.

7 one above and the otherbelow. The ends of the same are fitted with chain-wheels h h,

which are connected together by the chain 6. The bearings k of the vertical rolls are also guided by the guide-rod g, which runs parallel to and behind the screw f. The nuts Z Z are fitted to the top and bottom of the vertical rolls in the bearings 70 7c. The nuts Z Z are held fast on the screws ff by the locknuts m m. The bearings Zr are slotted in front at n, and can be pressed together by the screws 0 0, so as to prevent the nuts Zfrom turning in the bearings 70.

In order, for example, to move theleft-hand vertical roll,B, to the left and to' leave the right-hand one stationary, the screws 0 o of the right-nan d bearings, 7c, are loosened and those of the left-hand bearings tightened up. The lock-nuts m m of the left-hand bearings are loosened and the nuts on the left-hand side of the left-hand bearings screwed so far back as is required to move the left-hand vertical roll, B The screws f and f are now revolved till theleft-han'd bearings abut against the displaced lock-nut on the left-hand side, and the right-hand lock-nuts are tightened up, and the screws 0 0 of the right-hand bearings, 7c 7r, screwed up again.

The process of rolling round bar-iron in my improved universal rolling-train is as follows: The trains of rolls A A A, &c., are so set that the grooves are in the proper proportion. The vertical plain rolls B B B B B B die, are now set so that they press the bar sidewise as it passes through alittle smaller than the diameter of the grooves in the following horizontal rolls. When all the rolls are set and the guides at a a fastened in place, a piece of suitable iron is. fed into the first pair of horizontal grooved rolls A A, and leaves the same with a sectionsay corresponding to I, Fig. 9. It then passes through the guides a a to the vertical plain rolls B B, where it is pressed into the form II, Fig. '9, and passes on through the second pair of hori zontal grooved rolls A A, where it is rolled into a smaller diameter, III, Fig. 9. In the second pair of vertical plain rolls B B it receives the section IV, Fig. 9, and so on, passing through the different rolls, receiving the sections V VI in rotation until it passes through the last pair of horizontal rolls A A where the bar comes out finished, as in VII, Fig. 9.

Square iron is rolled in exactly the same manner; but instead of round grooves in the horizontal rolls square grooves are used. A piece of suitable iron is fed into the first pair of horizontal grooved rolls A A, and leaves the same with a sectionsay corresponding to I, Fig. 10. It then passes through the guides a 0b to the vertical plain rolls B B, where it is pressed into the form II, Fig. 10, and passes on through the second pair of horizontal grooved rolls A A, where it is rolled into a smaller diameter, III, Fig. 10. In the second pair of vertical plain rolls B B it receives the section IV, Fig. 10, and so on, passing through the different rolls, receiving the sections V VI in rotation until it passes through the last pair of horizontal rolls A A, where the bar comes out finished, as in VII, Fig. 10.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is
