MACHINE FOR ROLLING CAR-WHEELS SPECIFICATION forming part of Letters Patent No. 361,479, dated April 19, 1887.

:Application filed April 26, 1886. Serial No. 200,237.` (No model.)

To all whom it may concern.-

Beit known that I, THEoDoRE W. BEAN, a citizen of thc United States, residing at Norristown, in the county of Montgomery and State of Pennsylvania, have invented cert-ain new and useful Improvements in Rolling-Mills used in the Manufacture of Steel Car-Wheels, of which the following is a specification.

The purpose of my invention is to produce car-wheels of rolled and compressed steel, and I attain this object by means ofrolls, as shown in the accompanying drawings, forming part of this application, and in Which similar let; ters of reference indicate like parts.

Figure l shows a side View ofthe rolls and bearing.

F and G are two roll-heads, so shaped as t0 give the desired form to the steel ingot which is to be compressed by them into the eXactsize required.

H is another roll,whose periphery givesthe shape to the tread of the wheel. It will be readily noticed that it moves b y friction with F is given by means of the screw E on the rider N and allows the roll-heads to be separated sudiciently while the steel ingot is being placed between them on the table M.

S and C are suitable projections on the housing A, in which the horizontal roll H is journaled.

Fig. 2 shows a front view of the housings Vwithout the rolls F and Gr. Fig. 3 shows the housings B; Fig. 4, the arm C and` the bearings S for the roll H.. n

Power is applied to the shaft It. The ingot of steel having been cast to a suitable shape and sufficintly heated isplaced in position on the tubeM between the roll-heads. The screw E forces the rider N onto the roll F, and the steel ingot is pressed between it and the lower roll. The rolls I-I and G act as a die, while the upper roll gradually descends and compresses the metal, rendering it homogeneous throughout and of greater tensile strength.

I do not limit myself to two rolls for shaping the sides of the car-wheel, as it is evident thatthree or more may be geared directly together.

I am aware that mills for rolling iron carwheels have been patented before this application was made; but their construction differs materially in important details, and especially in the gearing of the two shafts. rlhe bal1bear ing allowing of the rocking ofthe shaft carrying one of the rolls is, as far as I am aware, also novel.

Having now fully described my said invention, what I claixn,and desire to protect by Letters Patent, is-

1. In a mill for rolling steel car-wheels, the combination, with a sliding bearing and aball or rocking bearing, of the shaft of one of the rollsjournaledfin said bearings and carrying a 'beveled gear-wheel placed between said bearings and engaging directly with the gearing on the shaft of the other roll, substantially as described. Y

2. In a mill for rolling car-wheels, the combination, with two or more roll-heads of suitable shape to form the sides of the car-wheel, of their shafts carrying beveled gear-wheels directly engaging one another and situated between sliding and rocking bearings, substantially as described.

3. Ina mill for rolling car-wheels, the combination,with a horizontal roll for shaping the face of the wheel journaled in stationary bearings, of two or more roll-heads of suitable shape to form the sides of the` car-wheel, and their shafts, each carrying a beveled gear engaging the other gear directly, each journaled on one side of the said gear in sliding bearings situated near the roll-heads controlled by 9 set-screws, and on the other in rocking bearings, substantially as described.
