To all whom t may concern: l

` Be it known that l, WILLIAM H. LESH, a

haveinvented a new and useful Rail Joint and Chair, of which the following is a specification.

The object of this invention is to -provide an improved construction for railway rail joints.

A further object of this invention is to provide improved means for supporting abuttingl end portions of railway rails.

A furtherobject of this .invention is to provideA improved means for connecting abutting end portions of railway rails so as to permit expansion and contraction` of said rails in any direction without damageto the connecting means.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claimsand illustrated by the accompanying drawing,'in which- Figure 1 is a plan of portions of abutting railway rails embodying my 'improvements. Fig. 2 is a sidefelevation .of the same. F ig. 3 is an opposite side elevation of the same. Fig. 4 is a vertical oross-secf tion on the indicated line 4`4of Fig. 1. F ig. 5 is aside elevation of a shoulder bolt employed in my construction and Fig. 6 is an elevation at right angles to Fig. 5. Figs.l

r 5 andv 6 are on a scale enlarged relative to the other views.

In the construction of the device as shown t-he numerals 10, 11 designate abutting end portions of railway rails. The ball or tread,

. web and central portion of the 'base of each rail 10, 11 is cut on an angle of 45 degrees as at 12 and the remaining portion of the base on each side is cut perpendicular to the longitudinaltrend of the rail as at 13.

The ends of the rails 10, 11 normally v.are

breaking or sagging thereof and sagging of the joint of the rails 10, 11. Angle fish* plates or splice bars 18, 19 are mounted on opposite sides of the rails 10, 11 and overlie thefjoint thereof. The splice bars 18, l19 are -spaced from the webs and base flanges of the rails to permit of expansion and contraction of the rails in any direction under the influence of changes of temperature independent of `the splice bars. Thesplice bars-18, 19 are secured to the rails 10, 11 by means of-spaced bolts 20 passingthrough their-verticalvlanges and through the webs of the rails and secured by nuts 21 ontheir threaded end portions. The bolts 20 are formed with-shoulders 22 (see Figs. 5 and 6) throughout a considerable portion of their lengthsand said shoulders are of elliptical formin cross-section, or are lat tened and formed with rounded edges'. In one dimension the shoulders 22 are of approximately the same thickness as the body of the-bolt as shown in Fig. 6, and in the other transverse dimension said shoulders are considerably thicker than said body. The shoulder .of each bolt 2() is received within and lits snugly to an elliptical hole inthe upright flange of the splice bar 18 and passes loosely through a slot 23 in the web of the rail 10 or .11. The.shoulder 22 projects slightly beyond the farther side of the web of the rail and the body of the bolt 20 vis received within andjlits snugly to a circular hole in the upright flange-of the splice bar 19 and the inner face of said splice barrests againstfthe end of the shoulder 22 -and is held thereby in spaced relations to the web of the rail. Thus -when the nut- 21 is tightened on the bolt 20 force will'be-applied to. draw the splice bars .18, 19 together so far as permitted by theshoulder .22, but no force will be applied ou, the web of either rail by the bolt or by either splice bar. The splice bars 1S, 19 also are secured to the rails 10, 11 by -means of spaced vertical `bolts 24 passing through their base ianges and through the base flanges of the rails on each side.

The bolts 24 are similar in construction to the bolts 20 above described and the shoulders thereof are received Awithin and fit snugly to elliptical holes in the chair 14 and pass loosely through longitudinal slots v25 in the'base flanges of the rails. The base flanges of the splice bars 18,19 resten the fao ends of the shouldersof the bolts 24, which shoulders project slightly above the upper surfaces of the'base flanges 'of vthe rails, thus supporting the splice bars -in spaced relations to said rails. The body' portions of the bolts 24' pass through and are fitted ,to circular holes in the base ianges lofthe splice bars 18, 19 and said splice bars are preferably formed with plateaus or bosses 26 surrounding said holesand formed with level upper faces against Which the nuts 27 are adapted to be screwed on the bolts. r1`hus when the nuts 27 are tightened on the bolts 24 force will be applied to `draw the base flanges of the splice bars 18, 19 toward the chair 14 so far 'as permitted by the'shoulders` of the bolts; but'no force will be applied-to the base anges of either rail by the 'bolt or by said splice bars. l

In practical use the trussed chair 14 provides a firm support for the rail jointl and prevents sagging thereof under the Weight of the rolling-stock. The diagonal cutting of the ends of therails 10,-- 11 causes them t-o form conjunctively a continuous tread ysurface and prevents undue Wearing of the endsvof the rails. The spacing apart of the ends of the rails and the formation foflon.- gitudin'al slots in the Webs and 4base iianges thereof to receive loosely the connecting bolts 20, 24 permits of longitudinal eXpansion'and contraction of the rails and the the nuts thereof b movement ofthe rails,

asis common in t e ordinary construction of rail joints.l

I prefer to make the chair 14 with outstanding apertured earsi 28, 29 on opposite' sides. of its respective ends, and to secure said chair to the ties 15, 16 by means of bolts 30, 31 passing through said apertured ears and through the ties. This lends solid- .ity to the joint and prevents creeping of the rails.

I claim as my ILnventlonw 1. A rail joint, comprising, 1n combination, abutting ends of rails, a trussed chair adaptedrto be supported at its ends and supporting abutting end portions of the rails, angle splice bars on opposite sides of and overlapping the joint between said rails, bolts connecting middle portions of said splice bars through the Webs of said rails,` said bolts formed with shoulders adapted to hold the splice bars in spaced relations to the rails, said rails formed with longitudinal lslots loosely receiving said bolts. and bolts connecting marginal portions of said splice bars to the chair and passing loosely through the base flanges of the rails.

2. A rail joint, comprising, incombination, abutting ends of rails, a suitable sup* port therefor, fish-plates on opposite sides of and overlapping the joint between said rails, and bolts fitting snugly in holes in said fish-plates and passing through longitudina-l slots in the webs of the rails, said bolts formed with Shoulders adapted to limit movement of said fish-plates toivard the Webs of the rails, whereby saidv rails may expand or contract in any direction Without damage to ,said connecting bolts.

A rail joint, comprising, in combination, abutting ends of rails, a' trussed chair .supporting end portions of said rails, angle ysplice bars mounted on opposite sldes of and overlapping the joint between said rails, bolts connecting said splice bars through the webs of the rails, said Webs formed with slots adapted loosely to receive 'said bolts, and bolts connecting said splice bars to said chair through the base flanges ofthe rails, said base flanges formed With slots loosely receiving said bolts, said splice bars being spaced by said bolts laterally and vertically from said rails.

Signed by me at Des Moines, Iowa, this 22d day of April, 1911.
