I RA IL-JOilYE EQ To all whom it may concern-.- 1 Be it known that I, W L ocK V; Zs nnn KEE, a citizen of the United States, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain-new and useful Improvements in Rail-Joints, of which the, following is a specification, reference being had to the accompanying drawlngs. I

- This invention relates to certain improve ments in'rail joints and has relation more particularly to a. device of thisgeneral character wherein is included a treadbridge piece and it is an object-o-ftheinventionto provide a novel and improved rail joint wherein pounding is substantially "en'- tirely eliminated as the rolling stock passes thereover; V a 5 I It is also an object of the invention-"to provide a novel and, improved rail. joint whereina tread bridge piece 'co-acts with' the meeting ends of therailsand partially straddles the web portions thereof together as willxbe hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood I will now proceed to de scribe the same with reference to the accompanying drawings wherein:

Figure 1 is a View in top pianillustrating a rail joint constructed in accordance with an embodiment of my invention;

Fig. 2 is a view in side elevation'of my improved joint with one of the fishplates or splice bars removed and the co-acting bolts shown in section;

Fig. 3 is a sectional view taken substan tially on the line 3-3 of Fig. 1;

Fig. 4 is a View in perspective of one of the fishplates or splice bars as herein employed;

Fig. 5 is a view in perspective of the tread piece as herein embodied; and

'g- 6 a'v ew i p rspecti e of the meet- 'spe mc'aaoaof Letter s latentl Patenwdflflili; Application filed"October-8,1917. se'rfar'mies'gsea ing end s of the rails as comprised in improved oint.

As herein disclosed thera'ils R aire 'ofa ny o'rdinary or suitable construction and'for'a short distance ba'cli -fromfea'ch-end the tread of each of the rails isi cut-awayas indicated a t-1 said cut 'portioa extending slightly with in the upper portion-of the web of therail'. 'lhe cut through tread of each of the rails is' preferably diagonal as-intl icated at 3;

The-'trea'dbridge piece'l compris s a tread is l of the same configurationwi'n cross section as the treads of theI-rails R- d is fo f a length substa ti lly equal to; combined length of the cutaway portions: 1 at -the' meeting ends of the railsa Asis illustrated particularly in Fig: 3 the tread bri'dgepi'ece T'- is initially, of a length slightly less than the combined length of the cut awayflpoi tis'ons 1 iii-order tocoanpensate for expansion. The opposite ends 50f the tread bridge piece Tare also: cut diagonally to. correspond with the cuts. 3'in the treads of the rails 'B so that when the tread. T is in applied or. assembled position-a continuous tread is afforded notwithstanding .the space" allowed for expansion, as V will be readily understood Depending from the tread bridge piece T are ithe transversely spaced flanges 6i e-X'-' tending the entire length of the tread bridge piece 10: and which area'd'apted to overlie'the opposite faces of the web's 2 oftherai'l's'R. The flanges 6 are each: of. ai width less than the width or height of the webs 2 of the rails as is particularlyillustrated in Figs.

2- and 3 of the accompanying drawings. Each of the flanges 6 adjacent its opposite ends is provided with the openings 7 adapted to register with the openings 8 produced in the webs 2 of the rails below the cut away portions 1 thereof.

Co-acting with he meeting ends of the rails and arranged at each sidethereof is a flshplate or splice bar B. The splice bar B includes a web portion 9 provided along its upper marginal portions .and at its opposite ends with the inwardly directed flanges 10.

The inner ends of the flanges 10 are spaced apart, as at 11 a distance substantiallyequal t0 the length of the tread bridge piece T so that the adjacent flange 6 of the bridge piece T will afford no obstruction to the application of the fishplate or splice bar B into applied position. The upper edge of the web 9 and the flanges 10 preferably engage the u der faces of the'tread T of the meeting ends of the rail while the lower marginal portion of the bar B is provided with an Each of the fishplates or splice bars B below the space 11 afl'orded between the flanges 10 is provided with the openings 17 adapt-- ed to register with the openings 7 and'8 hereinbefore referred to and insertible through each set of registering openings 7, 8 and 17 is thebolt 18 having co-acting therewith a clamping nut 19. As is particularly illustrated'in Fig. 1 it is preferred that the bolts 18 be oppositely directed.

The fishplates or splice bars B when in applied position and engaged with the bridge tread piece T as hereinbefore disclosed through the medium of the bolts 18 and coacting nuts 19'serve to effectively maintain the bridge tread piece '1 in applied position although it has been found of advantage to provide the outer end portions of each of'the fishplates or splice bars B with the openings 20 adapted to register with the openings 21 disposed through the web portions 2 of the rails'inwardly of the cut away portions 1.

Directed through the registering openings 20 and 21 are the bolts 22 havingco-acting therewith the clamping nuts 23. It is also preferred that the bolts 22 be reversely directed and also reversely directed relative to the adjacent bolts 18.

- From the foregoing description, it is thought to be obvious that a rail joint con structed in accordance with my invention is Games of? this patent may be obtained for particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated and it will also be obvious that my invention is susceptible of some change and modification without materially departing from the principles and spirit thereof and for this reason Idonot wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim: o V In a rail, joint, the combination of meeting ends of rails having their tread portions cut away, a tread bridgepiece fitting within the cut away portions of the treads, said bridge piece being provided with transversely spaced flanges overlying the opposite faces of the webs of the meeting ends of the rails, splice bars co-acting with the opposite sides of the webs of the rails and overlying the depending flanges of the tread piece, and

fastening members disposed through the splice bars, the flanges of the tread bridge piece and the webs of the rails, said splice bars contacting with the base flanges of the rails and the under facesof the treads of the rails, the upper marginal portions of the splice bars. being provided at their opposite end portions with longitudinally spaced and inwardly directed flanges, the space between said flanges being substantially equal to the length of the tread bridge piece,"the flanges E of the tread bridge piece being arranged within said spaces. r

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
