RAIL.

SPECIFICATION forming part of Letters Patent No. 624,471, dated May 9, 1899.-

Application led October 25, 1898. Serial No. 694,553. (N modem T0 all whom, t 71cm/ concern.:

Be it known that I, JACOB FINK, a subject 'of the King of Prussia, German Emperor, and

a resident of Paderborn, Prussia, Germany, have invented certain new and useful Improvements in Rails, of which the followingr is a full, clear, and exact specification.

The present invention concerns a two-part? rail for railroads, serving both as a rail and The two parts of the rail are of symmetrical shape and can be easily separated and reversed in i position.

The rail is composed of two angle-irons with reinforced flanges at the outer edges, both The outer faces of the angles are slightly concaved centrally in order to procure tighter compression of the heads of the rails and a more uniform distribution of pressure on foot of the rail. l

The new rail offers the advantage that it can be laid on the sleeper-plates of the crosstie, and the sleeper-plates may, if found de'- sirable, be slightly bulged. In this manner the two rail-halves will lie close to each other, with their vertical surfaces in contact, so that only the ordinary bolts are required.

In the accompanying drawings, Figure l shows the rail in cross-section, and Fig. 2 in ground plan on a reduced scale.

The rail consists of two symmetrical parts A and A' of the make shown in Fig. l. The outer plane sides b b2 and b3 b4 are dished or concaved at 2 3 3, respectively, while the outer edges of the angle-plates have .flanges a' CL2 a3 a4 of greater thickness than the intermediate portions. YVhen two such angleplates are laid together, as shown in Fig. l, the parts h2 b3 form the web, While the anges a2 a3 form the head of the rail, and the corresponding parts form the base or rail-foot, as at b b4 ct a4.

The straight surfaces of the angle-irons A and A are .in close contact above and below the concaved portions 2 3. The two angleirons are brought into correct position upon a sleeper-plate C, which is slightly concaved or dished on its upper side between the points 5 5. The round-headed screws d serve for the fastening, said screws reaching through the'sleeper-plate into the cross-tie.

When laying the rail, a strip e of wood or other similar material is rst pushed under the adjacent corners of the two angle-irons. Then the two angle-irons are fastened to the base by means of the screws d and to each other by means of the screws c. Thereafter the strip c is removed, and the screws are tightened until the lower surfaces of the rail parts and the upper surface of the sleeper-plate touch. In this manner the head and web partsvof the rail are irmly pressed to each other. The joints of the two rail-halves are in such a position toward each other that the face-joints of the one rail-half are situated in the middle of the opposite half of the rail.

By the present invention witha thoroughly reliableI seat and coupling of the two-part rail the result is that the two angle-irons can be reciprocally interchanged. As soon as the head parts a2 and a3 are Worn out the parts are reversed and the head parts a and a4 can be used as a rail-head, and the legs, which have worn bulging, can be employed as the base or rail foot.

I claimn A two-part railroad-rail consisting of two symmetrical and reversible angle irons, slightly dished or concaved centrally on their level faces, combined with a slightly dished or concaved sleeperplate C and securing means, substantially as described.

In witness whereof I have hereunto set my hand in presence of two Witnesses.
