FINISHING-ROLLS FOR THE MANUFACTURE or-uiow RAILWAY-SLEEPERS.
SPECIFICATION forming part of Letters Patent No. 377,948. dated February 14, 1888.
Application filed December1,1887. Serial No. 256,681. (No model.) Patented in England May 30, 1884, No. 8,428; in Belgium June 8, 1884, No. 65,362; in Luxemburg June 4, 1884, No. 408, and in France September 20, 1884, No. 164,401.
To all whom it may concern:
Be it known that I, ADOLF MliRKLIN, a subject of the King of Prussia, and residing at Hoerde, Kingdom of Prussia, have invented new and useful Improvements in. Finishing- Rolls for the Manufacture of Iron Railway- Sleepers, (for which Letters Patent have been granted in Great Britain, May 30, 1884, No. 8,428; in Belgium, June 3, 1884, No. 65,362;
m in Luxemburg, June 4, 1884, No. 408, and in France, September 20, 1884, No. 164,401,) whereof the following is a specification.
My invention relates to rolling-mills for the manufacture of iron or steel railway-sleepers r 5 having the shape of an inverted flanged gutter; and the object of -the same is to form upon these sleepers, by thelast pass through the mill, inclined projections, such as are required at the bearing-points of the rails, in view of caus- 2o ing the rails to lean toward each other.
The improvement by which this object is attained consists in the combination together of two cooperating rolls having the requisite profile for finishing the said sleepers, and one of which is provided on its periphery with recesses, while the other one is either circular or made with corresponding elevations, the said recesses, or both the recesses and elevations, having such shape and being so arranged that in the rolling operation the desired proj ections will be formed thereby.
On the annexed sheet of drawings, Figures land 2 are two views of a pair of rolls, A B, having recesses and also elevations. Fig. 3 is 5 a longitudinal section of a sleeper produced by the said rolls, while Figs. 4 and 5 are transverse sections of the same on the respective lines 1 l and 2 2. v
The roll Ahas the cylindrical parts a a, and
c the roll B the like parts I) b, co-operating with the former to form the flanges of the sleeper,
whereas, by means of the groove a of the roll A and the projecting part b of the roll B, the gutter-like portion of the sleeper is produced.
In the bottom surface of the groove a there If the projecting part b of the roll B is made without the elevations d-that is to say, if it is circular-the sleeper will be rolled with the inclined projections e f on its outer top surface, while its inner surface becomes straight, the projecting portions, increasing in thick- 6 ness from c to the highest point and then diminishing again.
I claim as my invention 1. In a rolling-mill, the combination together of the roll A, having the cylindrical parts a a and the groove a, with recesses c c, and the roll B, having the cylindrical parts I) b and the projecting part 12, substantially as and for the purpose described. A 2. In a rolling-mill, the combination to- 7 gether of the roll A, having the cylindrical arts a a and the roove a with recesses c c g 7 a and the roll B, having the cylindrical parts I) b and the projecting-part b, with the elevations d d, corresponding to the recesses c c,
substantially as and for the purpose specified. In testimony whereof I have hereuntoset my hand in the presence of two subscribing witnesses.
, ADOLF MARKL'IN.
