Application filed June l?, 1922. Serial No. 569,178.

To all whom t may concern: y

Be it known that Lllnrn E. SALsIor-I, a citizen of the United States, residing at Bethlehem, Lehigh County, Pennsylvania, have invented certain new and useful Improvements in Rail Joints, of which the following' is a specification.

This invention relates to rail joints and particularly to rail joints in which the abutting rail ends are secured together by vsplice plates welded thereto or secured in position by bolts and by welding.

The heat generated in welding splice plates to rails is intense and frequently is injurious to the rails, when operations are carried out in accordance with the practice now commonly followed. The base flanges of the rail ends are especially susceptible to injury in this manner, the lower welds being made along the lower outer edges of the splice plates which usually lie where the metal of the rail base is thin and easily heated through. As a result of such heating the metal is weakened and the outer margins of the rail bases have frequently broken off under shock and vibration result-V ing from traffic, so that the entire joint greatly weakened.

` llt desirable to have the splice plates of the self centering type, that is, to have them so designed and constructed that theyT arrange themselveswith their webs substan.l

tially parallel to the webs of the rails when the plates are initially drawn into position by the tightening bolts. In order to fulfill this requirement the plates are formed with top and bottom bearing surfaces for abutment against the lower and upper surfaces of the heads and bases of the rails respec tively, these slxrfaces constituting gi'iide surfaces for the purpose mentioned.

ln accordance with the present invention the splice plates are formed with the desired bearing or guide surfaces so that they may be quickly and accurately assembled with the rails and at the same time, are so designed that their outer lower longitudinal edges which are adapted to be wel-ded to the rail bases, are displaced inwardly relatively to the bearing surfaces so as to be as close as possible to the webs of the rails to the end that the lower weld may be formed where the metal of the rail base is comparatively thick and not liable to be inj ured by the heat incident to the welding operation. t will be understood, of course,

that the bases of the rails with which the plates are to be used decrease in thickness in each direction from the webs toward the outer edges.

ln the accompanying drawings one form of splice plate is illustrated which fulfills the requirements above mentioned, and in the following description the construction of the plate will be described in detail. lt will be understood., however, that the exact form of theplate may be changed when the same is intended for different forms of rails and that various minor modifications are contemplated.

I. In the drawings: F ig. 1 is a side elevation of the abutting ends of two girder rails showing the plate in position; and

Fig. 2 is a section on line 2-2 ot' vlllg. l. a portion of one plate being broken away. l

The rails R are of the girder typeeach having the lower surfaces of the head 13 and 14 being downwardly and inwardly inclined and the upper surfaces 15 and 16 of the base l2 being upwardly and inwardly inclined.

a head 10, a web 11 and a base 12,

The splice plates are indicated at S and although of different heights are formed in the same manner. Each splice plate comprises a web 17 having transverse flanges 1S atits ends. The upper and lower edge surfaces of the web converge inwardly to fit closely against the corresponding inwardly converging surfaces of the head and base and the same is true of the end flanges 1S, the upper and lower surfaces of these lianges being so inclined. as to fit closely against the inwardly converging and op4 positely facing surfaces of the rail. head and base.

ln applying-'the plates to the rail ends. bolts B are passed through registering apertures in the plates and webs 11 of the rails and are 'gradually tightened to draw the plates toward the webs of the rails so that their inclined upper 'amd lower surfaces bear tightly against the corresponding surfaces of the heads and bases of the rails. WV hen the plates have been drawn into position in this manner welding material is applied as at 19 along the lower edge of the plates and as at 2O along their upper edges so that the plates are rigidly secured in po-` sition. l

lt will be seen that by the use of the end (hinges 18 the plates are provided with upthat those edges of the fed'ges of the rails. K j y p theoretical requirements "are realized 'and 1t will'be Iseen that' toy Lfabi'icate.
