RAIL JOINT BAR Original Filed April 25, 1950 2 Sheets-Sheet 2 June 28, 1932 GEORGE LANGFORD, OF JULIET, ILLINOIS, ASSIGNOR TO IYICKENNA PROCESS COIVIPANY OF ILLINOIS, OF JOLIET, ILLINOIS, A CGBPORATION OF ILLINOIS BAIL JOINT BAR Original application filed April 25, 1930, Serial No. 147,122, now Patent No. 1,814,835, dated July 14:, 1931.

Divided and this application filed February 24, 1931.

This invention relates to rail joint bars, and more particularly to bars specially adapted for use with worn rail ends.

This application is a division of my copending application, Serial No. 1417 ,122, filed April 25, 1930, for raii joint bar, now Patent No. 1,814,835, dated July 1 1, 193

A rail joint of ordinary construction comprises the rail ends and joint bars secured thereto at opposite sides thereof, by means of bolts passing through the bars and the rail web. These bars are straight laterally and have fishing contact with the head and the flange of the rail ends, the fishing surfaces of 5 the heads and the flanges of the bars being of uniform width. In such a joint wear occurs at the center one-third of the bar, in a short bar, or the center one-fourth of the bar, in a long bar. A short bar is approximately twenty-four inches in length and a long bar may be thirty-six inches or greater in length. This center wear of the joint is characteristic of rail joints of present construction, and the wear at the head of the joint is greater than the wear at the flange or foot of the joint.

'When the bars are initially applied in the joint there is draw space between the head and foot of the bar and the web of the rail. As Wear progresses, the bars are drawn inwardly to the rails, by bolt tension, to take up wear. Since the wear is at the center of the joint, and little or no wear occurs at the ends of the joint, the end portions of the bar resist inward movement thereof to the rail rendering it difficult, and in some cases impossible, to maintain tight fishing contact at the center of the oint. After the draw space has been. used up, or the joint becomes objectionably loose at the center portion thereof, the bars have to be removed and replaced by new or unworm bars. This raises the difficulty of obtaining tight center contact between the bars and the rail ends, due to wear which has occurred at the head and flange of the rail.

It is known to provide bars having increased fishing height at the center portion thereof, known as crowned bars, for fitting to worn rail ends. These bars have fishing surfaces of uniform width and, when applied Serial No. 517,685.

in a joint, the crowned central portion of the bar fits into the worn portions of the rail ends. in some instances, the end portions of the bar are flexed inwardly by bolt tension so that the center portion of the bar is held by spring pressure against the rail ends. In such a bar, however, the wear at the center portion is greater than at the end portions, which renders it diificult to maintain the joint tight at the center and necessitates increased crowning of the bars which may be applied to the rails after the crowned bars first applied have worn out.

It is also known to provide bars of abnormal fishing height, such bars being curved inwardly lengthwise thereof and throughout their entire section, the head, the web and he flange of the bar having the same degree of curvature. It is also known to provide bars wherein only one or two of the three members are incurved, the other one or two members being straight. Such a bar is known as a curved bar. A bar of this type with incurved head is objectionable in that the head projects outwardly beyond the rail head, at the ends of the bar, and the ends of the bar head are struck by the flanges of the wheels traveling upon the track.

I have found that the above noted obj-ections to the crowned bar and the incurved bar can be avoided by providing a bar having the upper outer corner of the head cut away at the end portions of the bar so as to narrow the head fishing surface at the end portions, thereby accelerating the rate of end portion wear as compared with center portion wear, so that the end portions of the bar will wear and be moved by bolt tension to the rails more rapidly than in the case of ordinary bars with uniform width of fishing contact from end to end. The flange fishing surface may be treated in the same manner when desired. The head portion of the bar so treated has the additional advantage, particularly in the case of a bar with incurved head, of avoiding projecting corners at the end portions of the bar which might be struck, on the inside of the track, by passing train wheels. This narrowing of the end portions of a fishing surface may also be accomplished by removal of segments at the inner corners of the head or foot of the bar adjacent a fishing surface. In all cases, the narrowing of a fishing surface of a head or foot member is accomplished, in part at least, by removal of a segment from the inner or outer corner of the member adjacent a fishing surface at the end portions of the bar. Bars with segments so removed from the outer corner form the substance of the present invention, applicable to crowned or uncrowned bars which may be longitudinally straight or curved, as a whole or having only certain members curved wholly or in part.

In order to obtain a clear understanding of the construction of the bar of my invention, it is necessary to consider the crowned bar and the incurved bar of the prior art, above referred to. The incurved bar of the prior art is shown in Figures 3, 4, and 5. This bar is of uniform fishing height and throughout its entire cross section, both the head and the flange of the bar, as well as the web thereof being curved inwardly. If this bar be considered as a flat strap, as in Figure 8, the outer line of each fishing surface would be made crowned by removing a segment from the outer portion of the bar at each end thereof, as indicated by the shaded segments 12-3.' The resulting bar would then have its outer concave curvature removed and retain an inwardly curved face. Referring to Figure 9, the fishing surfaces of the bar are inclined oppositely for contact with the fishing surfaces of the rail ends. Due to this inclination of the fishing surfaces, removal of segments from the outer fishing corners at the end portions of the bar results in lowering the ends of the outer edge of the upper fishing surface and raising the ends of the outer edge of the lower fishing surface so that this bar, when viei ed from the outer side has its outer fishing lines similar to those of a crowned bar, as in Figure 11, and when viewed from the inner side has its inner fishing lines straightor uncrowned as in the ordinary incurved bar. As one purpose of outer corner bevelling is to narrow the top fishing surface and the extreme top portion of the bar so that it will not project laterally beyond the side of the rail head, the top outer corner is bevelled outwardly and downwardly as along the surface 1--2 3 at the top of Figure 9, so that the extreme top portion of the bar, as well as the fishing surface, is narrowed. If this same corner were bevelled outwardly and upwardly or outwardly and horizontally, although the top fishing surface would be narrowed, the extreme top portion of the bar would not be narrowed, and in the case of bars with sloping top outer surface it would be widened. In the case of the bottom of the bar, the bevelling is outward and upward. As shown in Fig. 9, the bevelling off of an outer corner adjacent a fishing surface is directed outwardly and toward the hori- Zontal axis of the bar so as to increase the vertical angle of part of the outer surface of the bar adjacent the fishing surface whereby the fishing surface is made narrower at its end portions than at its center portion. At both top and bottom, the outer vertical extremities of the bar are in the planes of the respective fishing surfaces.

It is also possible to produce bars from crowned bars of ordinary type. In Figure 1" I have illustrated, in plan view, the crowned bar of Figure 2, this bar being shown as a fiat strap. The inner and outer sides of this bar are both straight lengthwise of the bar. If segments 1314.-15 be removed from the inner corner of each end portion of bar 16, the inner fishing line at top and bottom of this bar will be curved inwardly and the outer fishing line at top and bottom thereof will be straight lengthwise of the bar. The top and bottom fishing surfaces will thereby be made narrower at their end portions than at their center portions.

8 r on its outer corners adjacent the iishin g surface thereof and at each end of the bar, the

It will be understood that Figures 8 to 15, inclusive, shown as flat straps for clearness of illustration, represent angle, ii-beam, or any other type of bars providing for top in bottom fishing Contact their center s end portions. The present invention resides in bars with one or born fishing surfaces narrowed at their end portions by removal of segments from the outer corners adjacent fishing surfaces. The invention may be ap plied to crowned or uncrowned bars with or without lateral curvature considered longitudinally, or only partially curved wherein one or two of the he? i, web and foot members are curved, v er one or two i 'nbers b I n is preferably 21 1S particu a .ed to rail ends, st an d is not int-en 4. i l ly 1n the bars are welded, riv fastened iminovably to rail will be no moi em at and re the contacting iisl lVhat ll claim is:
