WILLIAM H. GRAHAM, OF PITTSBURG, PENNSYLVANIA.

MACHINE FOR'SEVERING THE. FLAN'GES FROM I-BEAMS.

SPECIFICATION forming part of Letters Patent No. 352,184, dated November 9, 1886.

Application filed December 22, 1885. Serial No. 186,490. (No model.)

.To all whom it ma concern;

Be it known that I, WILLIAM H. GRAHAM, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Machines for Severing the Flanges from Beams; and I do hereby declare the following to bea full, clear, and exact description thereof.

My invention relates to an improvement in machines for severing the flanges of beams from the web; and it consists in securing upon the shafts of rolls a series of rings and cutters, as will hereinafter more fully and at large appear.

To enable others skilled in the art with which my invention is most nearly connected to make and use it, I will proceed todescribe its constrnction and operation.

Figure 1 is a front elevation of myimprovement. Fig. 2 is a longitudinalsection of the same.

In order to utilize old steel beams, it is necessary to cut them up and remeltthem, and then rework them into the product desired. This mode is both tedious and expensive. By the use of my improved method the beam is heated and passed through the rolls and the flanges separated from the web at one heat and one operation. I

Inthe drawings, A is the shafts of the rolls, upon which are secured rings B C and cutters D. In the rings-B are grooves F for the reception of the flanges of the beam. The rings and cutters may be secured upon the shaft in any manner desired, so that they can be ad- The rings 0 are made in two sections, so that they" can be readily removed from the shafts A, and

said rings are held permanently in the shafts The beam to be cut is heated to the desired heat and passed into and through the groove E, the flanges of saidbeam entering the groove F. The cutting-edges of the cutters D will sever the flanges from the web of the beam. The web and flanges can then be worked into merchantable iron or steel of different forms. Where beams of different sizes are to be cut, the rings 0 are removed and the cutters D placed closer together or farther apart, as may be required to suit sizes to be cut.

Having thus described my improvement, what I claim is- 1. In a mill for cutting the flanges from the web of beams, the adjustable cutters D, the

outer rings, B, having annular grooves F, to

receive the flanges of said beams, the removable inner rings, 0, and the shafts A, having rolls A between said collars O, substantially as set forth.

2 In combination with shafts A, rolls A, and cutters D, the collars 0, made in sections for convenience of removal and dovetailed into cutters D, for the'purpose set forth.

In testimony whereof I have hereunto set my hand this 8th day of September, A. D. 1885.
