Specification of Letters Patent.

Application filed July 8, 1907. Serial 1N0. 382,773.

To all whom it may concern:

Be it known that I, Jor-IANNEs EBERDING, of Hanover, in the Province of Hanover, Kingdom of Prussia, German Empire, having invented certain new and useful Improvements in Rail-Joints, do hereby declare that the following is a full, clear, and exact description of the same.

This invention refers to a rail joint, the distinguishing feature of novelty of which consists in the combination of a splice bar, extends over the top -of the web of the rail, the head of the rail having been removed bottom plate which rests on the sleeper and supports about centrally, the ends of the two rails, in such manner, that the splice bar and the bottom late form a body consisting of one piece. aforesaid elements into one splice .bar the result is obtained that the rail ends laid in such a splice "bar transmit all'th-e vertical movethe Wheel pressure directly to the splice bar, and such movements are vice versa transmitted directly from the.

splice barto the rail ends; any material bending of the supportin plate. even after the lapse of a lon time y reason of its resting on the adjoining sleepers below the joint is thus avoided. The

joint formed according to this invention furthermore ofl'ers the advantage of giving a heretofore not attained perfect removal of the load from the rail ends, while the similar rail joints heretofore known only gave a one sided and therefore im erfect removal of the load.

' constructional example of my invention is illustrated in the annexed which Figure 1 is a vertical cross section of a rail joint according to my invention on line .A of Fig. 2. Fig. 2 is a plan, Fig. 3 shows a cross section on line BB of Fig. 4.

Fig. 4 shows in a plan view-a modification of a rail jointaccording to my invention. Fig. 5 is a perspective view of the splice bar according to my invention.

In order to laybare the webs i i of the two rail ends I) 6 two outs only are made through the head and web of each rail and according to the construction shown on the drawing, that is to say a vertical cut in the direction of the line 1-1, and a horizontal cut in the direction of the line 22. Thecut 1'1 is shown slanting on the drawing, but it may in this place, and ay the combination of these'two.

drawings, in

also without departing from the invention in question be made in any other straight or curved form as for instance at right angles to the longitudinal axis of the rail, in which case the remaining rail ends abut against the head part e of the splice bar a and a space has to be provided between the rail head end and the head part e, in order to give the rail the possibility of an unhindered change in length contingent on changes of temperature. The parts of the rail laid bare are now filled by the head part e of the splice bar a, which at the same time is provided with a supporting bottom plate (1 which at the same time supports the rail ends 0 0 according to the drawing in itsfull Width and rests on the ad joining sleepers below the joint.

The support of the rail ends by the bottom plate 01 is of course not required to the extent of the full width of the rail ends, but it sufficeswhen the same are supported es ecially in its middle part by the supporting hottom plate (1, in order to. prevent a one-sided suport or removal of the load on the rail ends. lhe supporting plate (1 may be provided with flanges h whereby the splice bar a can be fixed to the sleepers at the joint without the use of special fixing or hook lates. In order to enable the splice bar to he made of rolled steel, the flanges h and ribs 9 may also be entirely omitted, as will be seen in the cross section Fig. 8, and plan view Fig. 4, in which case the rail ends and splice bar'may suitably in usual manner be held to the sleeper m and kept from moving by means of hoo plates is (Fig. 3 and right side of Fig. 4), or else without hook plates by means of lur'n s n (left side of Fig. 4) or fixed directly on tlie sleeper by wood screws.

The splice bar a may for thepu ose of attaininggreater stiffness be provi ed on the outer side with ribs 9 and if required also on the inner side with a strengthening partas for instance of awidthf shown inFig. 5, at which lace the thickness of the part of the splice ar between the head part 6 and the supporting bottom plate d should'be about equal to the thickness of the rail webs i 73 plus the thickness of the lateral part of the splice bar a. By. such a stiffening of the splice bar by means of the ribs f and g the free head part e is at the same time secured still more against a possible bending or yielding in course of time, and also against a diminution of the distance between the lower object sought part of the head the supporting ottom strain at the upper side of the bared webs i i by the load rolling over the head part of the splice bar is also permanently prevented so that thus no wear whatever on the rail webs at this place can take place.

The object of this invention is to prevent in the most perfect manner possible any load coming upon the rail ends, for which pur ose the splice bar a with the head part e anr the supporting plate cl form one single strong body whereby the space, intended for reception of the rail ends, between the head part e and thesupporting bottom plate (1 is of unchangeable height, so that the rail ends thereln, provided they are fitted exactly, are in fact without any loa-d coming on them, as the head part, because of its rigid connection with the supporting bottom plate (1, transmits the blow coming on it to said plate di rectly. At the same time by the exact fit of the two rail ends between the head part e and the supporting bottom plate (1 of the s lice bar the result is obtained that the re ling load must pass over the splice bar without blows.

If in the laying of the rail joint the height of one or other of the webs 'i"i"should happen to be greater than the distance between the under side of the head part 6 of the splice bar and the supporting bottom plate (1 it may be easily reduced by a few strokes of a file. But if the height of the web 'i or 'ishould be smaller than the said distance, so that there would be play between the surface 7' and the under side of the head part e, then this may at once be remedied by lacing there thin steel strips or blades, the urability of which would be lasting in view of I the circumstance that this place is not exposed to blows. Or the exact fitting of the webs i 'i in thes lice bar a may in the latter case also be attained by making the pipper surface of the sup orting bottom plate s oping and by adjusta ly fitting between the same and the under side of the rail ends a wedge shaped plate which is inclined on its under side in the same manner as the supporting bottom late 11, in such manner that a erfect fit o the webs i, '5 in the splice bar and a secure bearing of the rail ends upon the wedge plate are obtained, thus always erfectly fulfilling the by t e present invention ends.

Claims.
