,This inventionrelates railway rail supits oo ectsto 1n- The ordinary railway rails;are usually united end to, end. by clamping devieesavhich lap over the confronting portions of the, rails at opposite sides and bear beneath the ball iointre'a-duiul against the opposite sides of heiveb at some LilStiZlKQ jliTUHI the ends of the rails.

The clamp devicesithus constructed bear substantially the entire length againstthe under face of the, ball tend upon the upper tace of the tie flange.

:Experinient and ohservation have, shown that when trains pass .over the rails ithe pounding of the Wheels of thevtrain, especiallythe very heavy locomotives now in use, has a 'tendency t0 deflect the confronting ends or the, rails and if the rail endsare se-' cured by; clamp plates of theaordinaryeconstruction in contact, i their Whole lengths, against :both the. ball and the tie; flanges, -and rigidly connected to the-Webs of the rail by a plurality of relatively heavy clamp bOltfS, this deflection occurs,;and the outer portions of the clamp plates are correspondingly huinped up or elevated, and While this,depression and elevation inay not :be evident to th e' eyezoif an obse1'ver,-1it is sufiicient-to cause a veryperceptible unevenness of motion to the train.

The clamp plates as ordinarily constructed are of uniform thickness and, widththroughout, and when depressedorbent down .013- posite the rail ends, they remain in bent ClOWIliPOSllElOll, especially if the depression is sufficient; to, destroy the elasticity of the metal;

WVhena train approaches a joint distorted as above described, the first hump, or elevation in the rail causes a slightmphill movement and thengdoivn hill toward the meeting ends of the rails and then; uphill again and over the second hump or elevation,. and 'this operation: being repeated by'eaeh WlTLGQlAlIl passing aggravates the abnormal condition,

and requires constant care and readjustment,

and the replacing otflthe impaired vplates, wh ch is a source of relatively heavy ejX- pense. i

The plates in coininon use are relatively heavy, but the Weight is not properly "distributed to secure the best results, andj one of the objects of the present inventionis to so construct the clanip plates asto properly distribute the Inateria'l by increasing the eight and thickness Where the gi eatesft strains occur and Without materially inereasing theiveight as awhole. y,

An he bjec th n-venftionj is (to r gidly support. the rails at thefln confronting ends and resist [the gtendeme (to gglei lection bythe poundingjor hammering of the rolling stock, and to effectually suppose the plates from deflection at the ends, and thus prod ce-an arching Q truss i e o fig r tion and prevent, the torniationof [humps or elevations abovej'the ends of the plates.

Figure 11 is .a vertical section through the terminal portions of the plates and through the rail as the parts are shown in Figure 8.

Figure 12 is aside elevation of the confronting ends of a pair of rails, illustrating the change necessary to'adapt the form of plates shown in Figures 8, 9 and 10 to the rails.

The improved device may be applied to rails of various sizes, but for the purpose of illustration is shown applied to the confronting ends of standardforms of rails including heads or treads 10, webs 11, and tie flanges 12.

The improved plateis formed of a body portion 13 increased in thickness intermediate the ends as shown at 14 and with a laterally directed-enlargement 15 arranged to bridge over the confronting ends of the rails, as shown.

It will be noted in the sectional Figure 3 that the body or middle portion of the plate comprising the enlargement 15 has its outer surface sloping downwardly and outwardly from its contact with the balls of the rails. It will be observed further that the inner side of the plate as illustrated has a recess formed therein and a portion below the recess is arranged against the webs of the rails. The construction described is found in practice to greatly strengthen the plate bythe addition of a minimum of metal and weight thereto, and to materially aid the permanent grip of the plate upon the rails.

Reinforcing ribs 16 are preferably formed on the outer face of the body portion 13 and merge at the ends into the body and also into the thickened portion 14 and the enlargement 15.

Near their ends the body portions 13 are formed with lateral projections 17 which bear upon the upper faces of the tie flanges 12, as shown more clearly in Figure 5.

The body portion 13 is reduced in vertical width toward the ends, as shown in Figures 1 and 8.

By this arrangement, it will be noted, the

plates bear by their thickened and reinoblique to the longitudinal axis of the plates,

and thus coact with the medial enlargement to accentuate the truss-like form of the plate.

Clamp bolts 18 extend through the plates with the enlargement 15 of one of the plates formed with an upwardly directed extension or lip 20 to bear against the sides of the heads 10 of the rails at each side of the confronting ends, the lip being on the plate which engages the outer side of the rail only to avoid interfering with wheel flanges.

A clamp bolt 21 extends through the enlargements 1a, the ends of the webs of the rails being formed with cut out portions to receive the bolt. This central bolt 21 is employed in addition to the other clamp bolts.

The clamp bolts 18 near the ends of the plates are disposed at a lower point than the other bolts, with the centre lines of the bolts in alignment with the centre lines of the adjacent bolts and the upper ends of the enlargements 14, to complete the trussing arrangement.

In the modified construction the adjacent portions of the heads of the rails are cut away in any suitable manner with the cut out portions inclined inwardly and upwardly and the adj acentportions of the enlargements 15 correspondingly inclined, as shown in Figures 10 and 12, so that the downward pressure imparted to the rails by the rolling stock will draw the plates inwardly, and thus materially assist in binding the parts together and preventing them from being forced away from the rails. The clamp bolt 21 supplements the binding action of the inclined portions 22 and materially increases the grip between the parts.

This is an important feature and materially increases the utility and efficiency of the invention.

By the construction shown the main bearing is disposed directly beneath the rail headsat their meeting points and the plates with their enlargements meet in pyramidal outline, and bear up under the load and hold up the rail, and being enlarged laterally the greatest resistance is disposed where most needed.
