To all whom it may concern;

Be it known that I, THEODORE -W. Beams citizen of the United States, residing at Norristown, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Rolling Oar-Wheels; and I do hereby-desists in a mill for rolling steel car-wheels, comprising one or more pairs of rolls, one member of each pair being mounted in sliding and rocking. bearings, the shaft of each roll being provided with a gear-wheel meshing with that on .its felly.

Furthermore, the invention consists in a mill for rolling car-wheels, comprising two or more roll-heads of suitable shape to form the sides of a car-wheel, shafts upon which the roll-heads are mounted, each ofsaid shafts being provided with a gear meshing with a.

corresponding one on its felly,and one of said shafts mounted in sliding and rocking bearmgs.

Furthermore, the invention consists in a mill for rolling steel car-wheels, comprising a table'upo'n which the ingot -to be rolled is placed, one or more pairs of roll-heads, whose shafts are provided with intermeshing gears, and one of which rolls is mounted in sliding and rocking bearings.

Furthermore, the invention consists in a mill for rolling steel car-wheels, comprising one or more pairs of roll-heads of suitable shape to form the sides of a car-wheel, and mounted upon suitable shafts geared with each other, the shaftof one men'iber of each pair being mounted in sliding and rocking bearings, and a horizontal roll for shaping the trend of the wheel and journaled in stationnry bearings.

Furthermore, the invention consists in a mill for rolling steel car-wheels, consisting in a table upon which the ingot to be rolled is placed, oneor more pairs-of roll-heads of a form to give the desired shape to. the side of the wheels, the said roll-heads being mounted on shafts; which are geared together, one member of each pair of shafts being mounted in sliding and rocking bearings, and a horizontal roll mounted adjacent to the table and of a shape to give the desired form to the tread of the wheel. I

I have illustrated the invention in the accompanying drawings, in which-'- Figure 1 is a side view of a portion of a mill constructed in accordance with my invention. Fig. 2 represents afront elevatiou of the boneings of the mill with the rolls removed. Fig. 3 is a detail view of the; housing, and Fig.4is a detail view showing the bearings for the horizontal roll.

In the drawings, A and B representhousings, in whichshafts P and R, carrying roll-heads F and G, are jonrnaled. These roll-heads are so shaped as to give the desired form to t mountedat its extremeouter end in the ball- .1

boxK in the upper bearing B. The construction of these parts is snchas to allow the roll'- head on the shaft P to be raised or lowered, the bearing acting as a stationary pivot. The desired pressure on the roll-head F is given by the screw E on; the rider N. This screw provides means for separating the roll-heads sufliciently to allow the steel ingot to be placed between them on the table M. The shafts P and R, carrying the roll-heads, are provided with bevel gear-wheels I and J, which intermesh.

H represents'a horizontal roll, the periphery of which gives the desired shape to the tread of the wheel, the roll being arranged in proper position relative to the roll-heads to accomplish this.

8 and 0 represent projections on thevhousing A, in which the horizontal roll H is journaled.

In the operation of the machine power is supplied to the shaft R. -The ingot of steel, having been cast toa suitable shape and sufforrn the sides bbrear-wheet ehafts upon ficiently-he'ated,,is placed inposition on the table M between the roll-heads. The screw-E is turned ,to force the rider N against the roll F, and the steel ingot is thus pressed between it'and the lower roll. The rolls Hand G act as a die, while the upper roll gradually descends and compresses the metal, rendering it homogeneous throughout and of, the greatest tensile strength.

I do-not limit myself to two rolls for shaping the sides of the gear-wheel, as it is evident that any desired number may be geared directly together. and that any number of pairs of rolls may be utilized.

I am aware that mills for rolling iron carwheels have been patented before this invention was made; but their construction differs materially in important details, and especially in the gearing of the two shafts.

,Havingthus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is'- n t 1. A mill for rolling car-wheels, compris -ng' one or more pairs of rolls, one member of each pair being mounted in sliding and rocking hearings, the shaft of each roll being proy'ided with a gear-wheel meshing with a corresponding one on its felly. p v i I A mill for rolling car-wheels,'oomprising two or more roll-heads of suitable shape to which the roll-heads are mounted, each of the shafts being provided with a gear meshing A mill for rolling steel car wheels, comprising a table upon which the ingot to be rolled is placed, one or more pairs of rollheads, whose shafts are provided ,with inter- 4o meshing gears, one of the shafts being mounted in sliding and rocking bearings, substantially as described.
