BAR PLATE OR RAII-JOINT BAR.

;Application filed May 18,

This invention relates to bar plates or rail joint bars, sometimes termed fishplates, applied to the side of railway track rals for the purpose of holding the rails end to end where they meet and maintaining then on a level and in line. v

An object of this invcntion is the production of a bar plate ot' the nature and for the purpose stated having parts specially forrned and arranged whereby it is believed the rail joints ina serve a longer' time and be better supports on the level and in alignnent than by any devices for like uses With which this applcant is familiar.

As exen'plifyingthe objects of this invention, it may be stated here that bar plates constructed and arranged in accordance with this invention have been applied to main line track rails of a Class 1 railroad, where nore than fitty trains daily have 'passed over the bars during the past five months. This trafiic reached a total of more than six thousand trains and an estinated wheel load aggregating five million tons. It is an object ot' this invention to provide bar platcs that will successfully withstand such actual service as those e nployed as stated have been found to do.

It is also an object of this invention to uake a bar of special metal having such form and structure that it will be when placed in position. at all times under tension vertically and horizontally.

-Another object` of this invention is the Construction of a bar plate that upon the approach of the wheel loads will re-act and hold the joint up thus carrying the wheel across the open line between the rails with a resilient and ficxible rebound.` I

Another object of this invention is the fashioning of a bar plate that when in position is always under tension, so that an outward pressure is constantly exerted against the nut and the bolt head and shank which prevents theni from working loose, 'and at the same time equally holds the bar against displacenent in an direction; i

To deterinine t e preferred form bars made in accordance with this invention were subjected to three hundred tons pressure 1928. Serial No. 278,766.

released the bar jumped upwardly a foot or nore on the press thus proving its spring quality vertically. Bars made in accorda'nce with this invention were then tested by laying the bar down on its fiat side, the part that bugs .the web, on the table and a steel block three-fourths ot' an inch thick was placed under the end of the bar. Like pressure of three hundred tons was applied, and

when released the bar re-acted springing froni the table.

It is also an object of this invention to pernit bars to be n'ianu'factured cheaply in accordance therewith of any size usable with railway rails of any size or weight.

So far as the knowledge of this appiicant extends, bars of present day or ordinary type are rolled froni hot billets and fit under a -snall outer part of the rail head or throat the rail head hearing .o1"`resting down on a part of the bar plate on its top edge throughout its length and leaving a space between the bar and the web. The wave motion in the rails causes a lever action by such bars as they are now applied to`the joints which wears the rails under the heads at the joints and on the top edge of the bar at the joints at the same time. This wave or lever action wears the underside of bolt heads and causes the head to wear into the side of the' bar plate or 'this lever action in the rail causes these bolts tothrough andareone thickness and width from one'end to the other and when applied to the rail they have a dead, paralyzed or a slu gish action in contact with the rail and the wear on them as above described nakes it impossible for it to have tension both Vertical and horizontal which is -very a edgewise, the bar being set up in its regular\ -View of two rails meeting end to end and and intended position. As the press ure was having .this invention applied thereto.

Figura 15, is a longitudinal sectional View showing all the parts assembled, when the ends are drawn inward to an extreme final osition against the web 'of the rail the ars at all times having tension and bolts likewise as shown.

Figure 16, showsa half :full size Vertical or cross section onpthe broken line 16-1G of Figure 1, llustrating the position of the bolt when first applied and slightly tightened andbefore drawing the ends of the bars inward to the railweb. The bolt hole 15 is' one of the oval holes, and to clear the In this figure( the bolt is shown top side of the body of the bolt so that when the bolt is tightened and the bars are pulled inward and upward at their ends` the bolt will have clearance in order that the joint or bar ends can be raised.

Throughout the drawings and description the same number is employed to refer to the same part.

Considering the drawings, Figure l shows the rails 1 and 2 with the bar plate 3, in :iccordance with this invention, placed across the meeting` line of the rails and upon the flanges ot' me rails. In this Figure 1 is shown also the thickened middle portion l of the bar, with the added reinforce 5 increasing downwardly in length and thickness. The ends of the bar are desiguatcd (3 and 7, and their upper edges 8 and 9 are dropped somewhat below the under surface of the heads of the rails. The bar has the end flanges 10 and 11 resting upon the flanges of the rails, and these fianges may have Vertical strengthening ribs 12 and 13. Bolt holes 14 and 15 pass`through the bar. The two middle holes are slightly higher than the'two end holes and it will be observedthat the hole 15 is oval or oblong and wider at their mouth tapering inwards` towards the rail.

In Figure 2 the side of the bar next to the rail is shown, and its middle thick portion is longest at the tap.

In Figure 3 the middle thickeued and reinfo'eed portions are shown together with the end portions or wings which before being clamped to the rail are. spaced from the web of the rail at a gradually increasing distance from the terminations of the thickened middle portions.

Figure 4 illustrates the lower portions of 'the middle and end portions of the bar, be-

'fore being clamped to the web .of the rail.

Figure 5 shows the tops of the middle thickened portions of the bar arranged against the web of the rail.

Figure 6 shows two meeting rails and the arrangement of bolt holes that n ay be made to engage the bars of this invention. Some of the holes are of oval form. This inven- .tion i's in no way limited toithe nunber or form of the bolt holes.

Figures 7, 8, 9, and 10 show vertical sec- 'tions of the positions of diflerent parts of the bar plate with respect to the-;head and web and flange of the rail, before the bolts are inserted and made tight. The form of thethickened middle portion and of its reinforceadded portionis shown in the Figure 10.

In Figure lLthere are shown two meeting rails 16 and 17 with a modified bar 18 arranged against the sides of the. rails. The bar has three bolt holes 19, 20 and 21. It

will be noted that the 'hole 20 is slightly higher thanthe other holzs, and that the llO added reinforce part of the thickened middle portion 22 is now omitted to allow for the bolt head and nut. But, the rib 23 remains as before across' the lower middle por-' tion of the bar to assist in taking care `of the blows and weight and to add to the` large bolts for st-rength.

As shown in Figures 13 and 14, it is advantageous to use a bolt 27 with anenlargement or throat 28 near the head of the bolt. It will be noted that the bolt hole in the bar :is tapered correspondingly with the -enlargement 28, and this construction insures a perfectly tight' joint what-soever the hurry may be on the part of the track layers. It is to be understood, however, that this invention is in no way limited to any particular shape v of the bolts or bolt holes.

In Figure where .the ends of-the bars have been forced into their extreme or final position against the rail web, and the bolts and bolt heads, as well as the bars themselves, are under constant tension as will be noted by the space clearing the web between the thickened middle portion and the extreme end portio'ns of the bar plate. Wheel loads passing in any number can not shake the` bolts loose, and the bars re-act Upwardly having a tendency to lift the load or throw the force from the joint in the same direction as the wheels of the car approaching the meeting.- line of the two rails or when it passes over the' joint to throw it beyond in the direction the wheel is moving.

In F igure 16 the rail 2 is shown in section, with the bar plates 3 clearing the sides. The bolt 29 has been tightened, or this sectional figure may be taken as a section through the bar plates near their ends and the rail after the ends of the bars have been or tightened to its extreme, or under 'a heavy` wheel load, or the rails bending` down over the'bolt hole would clear the bolt and throw the pressure or weight to the' joint at the thick middle portionof the bar where it is intended, and as heroin before described.

The bar will fully recover its first shape after the loadhas passed and the bolts can not work loose.

It will be unde'stood thatthe bar herein specified has a cambered effEJ't both on its top edge and hack side, fitting; the rail, so upon the approach of the load, and When on the joint, the rail heads and ends immediately function by the springy action or tension qualities of the bar, the direction thereof being both vertical and horizontal thereby counteracting the load or Stress trial location.

It is believed that the drawings so fully I illustrate this invention, taken with the fore- 'going description, that an explanation of the operation in detail is not necessary. A joint or bar plate fashioned and constructed in accordance with this invention has the effect that when the wheel load is directly over the middle of the bar or at the meeting line of the two rails, the weight is always equally distributed and taken lip by the bar through out its entire length, width and thickness, and the wheel load does not throw a strain oh any particular part of the bar or -on any individual bolt as is now frequently the result with ordinary fishplates. When a wheel approaches a joint equipped with this invention, the ends of the rails are always supported and held up and carry j the wheel across the joint. The ends of the rails do not dip or butter 'as the action ofthe bar plates under the approaching wheels is to throw the joint up in a reflex action and the rail' ends are brought solidly together and hold themselves in a straight line.
