RAILWAY- RAIL JOINT.

SPECIFICATION forming part of Letters Patent No. 609,853, dated August 30, 1898. Application led December 27, 1897. Serial No. 663,593f (No model.)

To all whom t may concern:

Be it known that I, ALWIN VIETOR, doctor of philosophy,a subject ofthe King of Prussia,

German Emperor, residing at Wiesbaden, in

the Kingdom of Prussia, German Empire, have invented anew and useful Railway-Rail Joint, of which the following is a speeiiication.

The invention relates to railway-rail joints Io which are provided with an auxiliary rail arranged aside of the joined ends of the main rails on the outside of the track and fastened on the sleepers, as shown and described in Letters Patent No. 532,421. Such auxiliary I5 rails have a top surface which slopes toward both ends; and the invention consists in a rail having such sloping surfaces and capable of being produced at a lower price and with a higher degree of durability. Up to t0- zo day the auxiliary rails are rolled as' the ordinary railway-rails and cut in pieces of proper length. Then the upper surface of the railhead is made sloping at both ends by planing, milling, or the like. This work is very expensive and the inclined surfaces shaped in such a manner are more liablev to Wear than the intermediate horizontal part of the top surface of the rail-head, this middle part being still coated with the r0lling-skin,which 3o has, as is well known, a superior strength.

According to the present invention the sloping surfaces in question are produced by pressing down the ends of the head of the auxiliary rail either still hot from rolling or reheated, so that the web is compressed and the head of the rail Ylowered at both ends, while the foot of the rail keeps its straight shape throughout its length. lVhen applying suitable dies, the lowering of the rail-head ends may be facilitated by bending out the 4o web ends. This method is very cheap and preserves the rollin g-skin even at the ends of the rail-head.

Figure l represents an elevation of a rail-` joint with an auxiliary rail, the head of the latter being bent down at'both ends to produce inclined top surfaces. Fig. 2 is a crosssection taken along line 2 2 at Fig. 1. Fig. 2a is a similar cross-section showing doubleheaded rails supported in chairs. Figs. 3 and 5o 4 are cross-sections on lines 3 3 and 4 4 of Fig. l, respectively.

The middle part of the auxiliary rail a is of equal height to the track-rails l), while at the ends the rail-head is sloping, the web being bent out at a0 in proportion to the depression of the railhead. A double fish-plate c may be placed between both rails to stiften the joint.

What I claim as my invention, and desire 6o to secure by Letters Patent of the United States, is-

In an auxiliary rail for railway-rail joints the head pressed down at both ends and the web bent out in proportion to the depression of the head, essentially as shown and Vdescribed.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. Y

ALWIN VIETOR. Vitnesses:

RICHARD PRIEST, CHAs. H. DAY.
