-My invention-has to do with improvements in rail c'rossing. -structures.

Asa train moves along a section oh-track it. sets up. in. the m a vemcar up-and-down waveor floating motion of the rails. =In prior crossing constructions this motion has resulted inlooseninghthe hold down nieansandfiin excessive wear on the bracing, ties andballast.

the wedge 26 is driven into position between brace member 25 and the stop member M. A series of holes 36 are provided at the narrow end of the wedge member 26 in the projection 21 to receive the cotter pin '28 to hold the wedge in position. The grave member 25 is shaped so that it engages the top of the outer base flange of the guard rail at 3| and beneath the head of the guard rail at 32.

The rail assemblies comprise interchangeable inner assemblies 33, 34, 35 and 36 as shown in Fig. 1. These inner assemblies are first slid in place on the base plate ID in the assembling process. The hold down guides I2 and I3 have portions 31 (Fig. 3) spaced from the base plate so as toreceive with slight clearance the outer base flanges of the rails l8 and I9 when the assemblies are slid onto the base plate in a direction along their longitudinal axes. The inner assemblies are positioned so that their ends are spaced from the gauge lines, which coincide with the inner edge of the top of the running rails i1. This spacing is the width provided for the flangeway, as shown in Fig. 3.

Rail assemblies 38 and 39 are provided at each corner which include short sections l8a, l9a, 26a, Zla of the false flange riser rail, the guard rail and the two filler members, respectively, and a somewhat longer section Ila of the running rail. The guard rail section |9a may be cut away at 4| to assure proper clearance for the wheel flange. These assemblies are slid into position on the base plate in the same relationship to the hold down guides as the four inner assemblies. The

view in Fig. shows a rail assembly 39 in proper" position while the adjacent rail assemblies 34, 36 and 38 have been moved away from the point end structure of the respective rail assemblies.

When in position these corner assemblies are in abutting relation with each other and with the inner assemblies at their point of intersection. This relationship is such as to provide clearance through the intersection for the flange-way. After the corner assemblies 38 and 39 have been slid into position they are locked in place against longitudinal movement on the base plate. Stop members 46 are welded in place on the base and prevent movement of these assemblies in a direction of their longitudinal axes except for the running rail Ila. The running rail Ila, being somewhat longer abuts the running rail of the main line and thus is prevented from moving longitudinally. The positioning of the corner as- J semblies locks the inner assemblies in proper position and prevents them from moving in the direction of their longitudinal axes. All the rail assemblies are then secured against transverse movement by the proper positioning of the brace members I5 as shown in Fig. 1.

The brace members l5 are placed opposite each other and restrain movement of the assemblies in a transverse direction. The construction of these brace members is such that a limited vertical movement of the rail assemblies is permitted. In this manner the rail wave motion which is inherent in train movement is not eliminated but is controlled. The motion is permitted to a lim- 4. ited degree. This construction does not involve any bolts or welding or other securing means between the brace members and the rail assemblies.

In order to cushion the movement of both the base plate and the rail assemblies, resilient means are provided between the rail assemblies and the base plate and beneath the base plate. As shown in Fig. 3, a resilient coated fabric 42 is provided beneath the base flanges of the rail assembly members. A resilient cushion member 43 of rubber or the like is provided beneath the base plate I0.

While the illustrated embodiment of my invention is shown applied to a right angle crossing it will be apparent that my invention is applicable to a crossing at an oblique angle.

The specific abutting relationship of the rail assemblies at the points of intersection which is illustrated is preferred in order to obtainthe maximum of interchangeability of the assemblies and their component parts, but it is contemplated that the relationship may be modified for reasons of fabrication of parts or the like or because of special conditions at the point of crossing and the specific relationship is to be taken as illustrative only.

The stop members 40 may be welded to the base plate ID or otherwise provided thereon when the hold down guides l2, l3 and stop members [4, l6 are provided on the base plate, that is, prior to placing the respective rail assemblies on the base plate. When the respective assemblies are then placed on the base plate l0 the component parts of the assemblies may be slid into place, separately, with the running rail sections inserted last. This arrangement eliminates all welding at the time when the crossing is installed.

Modification of the structure and changes in the materials within the scope of my invention will be apparent to those skilled in the art.
