In the drawings, the letters a to m represent the vertical rolls which are journaled in the housings 3 and 4 and are connected with the driving spindles 5 by the wabblers 6. Keyed to the lo'werend of the spindles 5 are the bevel-wheels 7, which gear with bevelwheels 8 on the shaft 9, so that each roll is driven by power directly from the power-shaft. In the face of the rolls 2 are grooves 10, which form the flanges of the beam, and these grooves, as well as the space between the rolls, diminish in size with each pass of the series from a to m, so as to reduce the thickness of both the flanges and the web of the beam with each pass. On each side of therolls 2 are the feed-tables a tow, having feed-rollers 11, which are driven by suitable mechanism in the direction of the arrows marked on the drawings. The rolls a to m are so constructed that they may be adjusted in-relation to each other by suitable mechanism, not shown in the drawings,so as to increase or diminish the space between the rolls on any or all of the different passes.

The operation is as follows: The I-beams or channel-beams as they come from the cogging mill are delivered withtheir webs in a vertical position to the feed-table 'a', and are assed between the rollsa b to the feed-table By suitable transfer mechanism, not shown in the drawings, the shape is then transferred to the feed-table c and passed between the rolls 5 and c, and so on until the finished beam is delivered on the table w.

will be ap- 'I he rolls are much cheaper, being smaller in length than the horizontal rolls now in general use and hence are easier to replace in case of breakage or change from one shape to another. As one roll is used in two passes a minimum number of rolls is required. They are also much stronger owingto the short distance between their bearings, and, being on the same level, can be easier adjusted than if arranged three-high, as now mostly used. As the rolling is all done on one and the same horizontal plane and the feed-rollers turn in the proper direction, the use of tilting as well as transfer tables is avoided, and a continuous rolling of the shape is accomplished, making it less expensive to roll and increasing the output or tonnage over that of the present method. Each roll is also driven independently by power derived directly from the tions, wabblers, and rolls are greatly reduced from those existing in the present mills, hence causing less breakage.

Although I have shown rolls adapted to roll I-beams, I do not desire tolimit myself thereto, nor do I desire to limit my invention to-the use of the particular devices shown and described; it being understood that for channel-beams which are not symmetrical about their vertical-axis, suitable means must be provided for turning this shape, so as to set it in proper position for entering the consecu tive passes.

I am aware that vertical rolls used singly or in connection with horizontal rolls are not new.

I am also aware that vertical rolls have been used in rolling tubes, and I do not desire to claim the same broadly.

Having thus described my I claim, and desire to secure out, is-
