EAILVIAY-RAIL JOINT BAR.

Application filed August 20, 1928.

particularly effective tor-lifting the rail joint up and for holding the meeting ends of railway rails in lasting; positions a'lter they are laid down, and which will not work loose and give a rebound or reflex action at the joint as the wheel loads pass over the "ails. I v I In this instant invention the joint bar is made up oi two separable members lilting together as hereinafter descr bed, one o pieces being shorter than the other. shorter piece fashioned to lit against the web ot a rail in contact with the under side or ball part of the ma, and upon the top of the rail base. The longer member is made to project beyond the ends of the shorter member and to be placed upon the outer surface oi the shorter member, and torest on top (it the base of the rail. shorter members are arranged upon oppo- Silo sides oi the meeting ends of the rails, and they are secured by ludts passing th roi 4gb the members and through the rails.

it is an object of this invention toitorm the shorter n'lember to {it the side 0'! the rail from the ball to the base or il'hmge, and to Follow the curve oi the side of the web of the rail which thinnest at its middle longitudinal line and gradually thickens towards the ball and base. The shorter mem her is substantially o'li wedge-shape as illustrated and described herein, and the pound- .iu oi? the wheel loads passing over the joint ot the rails drives the rail ends and the wedge-like shorter. member downwardly with the eii'ect of tightening; the grip o t the belts.

It is also an obiect of this invention to make the longer member of this invention oil spring steel in order that it may po, less considerable elasticity when bent fiatwise or edgewise. When the ends of the longer member which extend beyond the ends of theshorter member are drawn towards each tithe the bolts for tiltnigh the rails Such longer and Serial No. 300,808.

the whole joint fastening is under constant tension and all parts are held. firmly yet in a degree yieldingly up to level and in a straight track line.

e A nun'iber of modifications of this invention are shown in the aeconipaning drawings, and it will be understood that these partieular conformations are in no wise intended to represent all the configurations that may be given the members of this invention but are merely illustrative of advantageous constructions. This invention is not limited to any sol-cited size or shape of the members or to the innnber of bolts or the positions thereo'l, as various changes of such adjuncts will readily suggest themselves to those familiar with railway appurtenances and track construction.

Of the drawings Figure 1 represents a ver tical section through a railway rail equipped with this invention.

Figure 2 is a vertical section similar to that set out in Figure 1, showing a modification of the contacting surfaces of the inner ant. shorter and outer and longer members.

Figure 3 is aside View of the meeting of two railway rails having this invention in position to s cure the joint, and showing one location of the bolt holes.

Figure 5 represents a section of an arrangement ol? the parts of this invention as illustrated. in Figure 1, and shows a modil ed and recessed term of the contacting sur lives of the compounded members.

Figure 6 sets forth a vertical cross section of a railywith a modified form of this 'inven tion ai uilied thereto and secured by a. bolt, loclc washer and nut 0t custoi'uary nature. In this figure the contacting surfaces of the two l'nenjlbers are curved, but the wedged-own character of the inner and shorter member is preserved.

Figure 7 is a similar view to Figure (3 with the inner or wedge member omitted.

Figure 8 represents a longitudinal s1. ,tion of the web of a rail joint showing the joint bar plate members constructed in accordance with. invention. in section length-w The positions of the bolt holes are exhilited in this figure with conically enlai o'ed or expanded mouths provided for certain of the bolt holes.

Figure 9 is a face view of the outer side of one of the longer members.

Figure 10 is an inside surface view of a longer member.

Figure 11 is an outer face view of a shorter member.

Throughout the drawings and description, the sai e number is used to refer to the same part. i

Considering the drav-iings, Figures 1 and 3, it will be noted that the rail Slim '11 for the purposes of this explanation has the head or ball designated by numeral 1, the web or vertical part 2, and the base 3, having upper outw rdly and downwar-(lb .nting surfaces marked 4- and 5. it vii be observed that the web 2 is thinnest in the i-iiddle an ex' ands or thickens gradually upwa dly o the head 1 and downwardly to the base 3, and

that the member (3 of this invention 1 r anged as con ,in contact with the web 2 fits the web, the lower partof the bal and the portion of the upper surf base of the rail next to the web. thcr be seen that the outer face or surf e of the member 6 is not vertical, but inclines inwardly and downwardly, which gives to the member 6 a distinct wedge shape. In contact with the member 6 is disposed the outer member 8, the top of which is slightly below the ball of the rail, ant, its inner face or surface 9 corresponds in slantand lies in contact with the outer face 7 of the member 6. The lower endof the member 8, marked 10 has the same inclination and rests upon the surface at of the base of the r il.

In Figure 3 two railway rails 11 and 12 meet, and this invention applied thereto.

t is now shown that the outer member 8 is the longer and that it or ends at the ends beyond the ends of the inner member 6 which is the shorter member. It is held within the purview of this invention to locate three

bolt holes

13, 14 and 15 as illustrated in Figure 3, the middle hole 14 being slightly higher from the rail base and passing between the ends of the meeting rails. The invention, however, is not limited to that disposition of the bolt holes.

A great variety of shapes may be readily devised for this invention, but the wedgelike form of the shorterplate or member and its wedge action under the wheel loads is retained.

As set forth in Figure 2, the modified form of this invention comprises the rail 16, the inner member 1? fitting the web, ball and base of the rail as before, and arranged in contact with an outer and keeper member 18 as explained. But the contactinp' surfaces of the inner and shorter member 17 and the outer On! it will f andlon g'er member 18, ignated 19, 20, 21, 22 and 23 for the shorter member, have corresponding inclines for the contacting surface of the outer member 18. Nevertheless, the wedge-formed shape or" the inner member 17 is preserved. The same is true of the modi fied constructions set forth in the Figures 4 and 5. In Figure 4 the rail has immediately against it the inner member 25 fashioned with-a serrated outer surface 26, and the outer member 27 has a like surface co .taicting with th rail 28 the inner member. In a c i ad base the inner the inner member 33 is thicket -l that its wedgedike cross sectioi s preserved. A bolt 87, provided with the usual spring washer 38 and nut 39 is shown passing through the members and web of the rail in Figure 6.

Figure 7 illustrates the same parts as set out in Pi nic 6 with the inner member 8-3 omitted, to show the wedge-like seat or space which the inner member occupies. This figure may also be tall .n to represent ZtSCUtldl vertically through the ends of the longer member Jeyond the ends of the shorter member, and this figure will be again referred to.

Figure 8 is a section longitiidinally through the webs of meeting rail ends l0 and 41, showingthe shorter member a2 and longer member $3 on one side of the rail oint, and the shorter member and longer menr ber on the other side. The locations of the bol holes and i? are also set out, and these holes may have expanding mouths, or, as illustrated in Figures 9 and 10 the bolt holes a? of the longer member a3 may have mouths of elliptic. l shage. i his invention in no way limi ed 0 the 'orms or locations of the bolts and bolt roles, d the bolts may or may not have err-,amled portions near their heads to engage the expanded bolt holes shown.

Figure 11 shows an outer face of a orter member 48 made in accordance with ii A, invention. I

Either the longer or the shorter members of this invention as illustrated and described iray l e rolled from and in one piece by suite et-up of rolls, and then cut into proper 1s. 'ar ling the operation of 1 modified forms as well as sidered in connection with Figure 1. Suppose the bolt 37 in Figure 7 has its counterpart in Figure 1 drawing the ends of the outer members towards each other beyond the ends of the shorter members. It is believed to be clear that the lower face or surface 10 of the longer member 8 will tend to slide upwardly towards the web of the rail as the bolts are. tightened. In other words, the tighter the bolts, the greater will be the lifting eli'eet upon the shorter and inner plate and upon the under sideol the balls of the rails at their meeting line. The ell'ect of the wheel loads is to exert tension upon the bolts, and the greater that tension may be the greater will be the lifting el'l'ect or resistance oi the rail joint constructed in accordance with this invention.

The two piece rail joint bar constructed in accordance with this invention can be made oi any length, thicknessor width, and the outer member may be of good grade of steel in order that it may possess as fully as may be t esired elastic capacity both sidewise and edgmvise. Bars as described herein can be applied to and used on any rails, whether those rails be carried on ties of wood, metal or concrete, and upon any form 01 tie plate, but most advantageously upon the ties and tie plate constructions devised by this applicant.
