RAILWAY-RAIL JOINT.

Application filed November 2, 1921. Serial No. 512,342.

1921), of which the following is a specification.

. This invention has relation to the joinlng or splicing of railway rails.

The invention, which is applicable to bullheaded or flat bottomed rails, has for its object the provision of splice bars which shall prevent creeping of the rails and sinking of the joint or splice.

The invention also has for object to provide improvements by means of which other advantages shall be obtained.

. Referring to the accompanying draw- 1ngs:

Figs. 1 and 2 are elevational views of the outer and inner sides of the rail splice.

Fig, 3 is a cross sectional View on the line AB of Fig. 1.

1, 2 are two rails to be spliced together. 3, 1 are splice bars that are secured to the inner and outer sides, respectively, of the rails. The splice bars 3, 4 are flanged along the upper and lower portions of the web,

the upper flange 5 being shaped to corre spond with the underside of the rail head 6 so that it may seat thereon, and the lower flange 7 being, at the end of the splice bars,

horizontal as at 7, and, atthe central portion, more or less vertical as at 7", the horizontal portions 7 and the more or less vertical portions 7, being united by a sloping portion 7, spaced and arranged as" shown.

9 is a cross tie having a sole plate 10 on its upper face: the cross tie extends across the track and two are employed, one on each side of the lines or surfaces of contact of the rails 1, 2. The splice bars 3, 4 are of such length that they bridge and extend at each end beyond the cross ties 9. The splice bars 3, 1 are bolted to the rails 1, 2 on each side of the line or surfaces of contact thereof, one splice bolt 8 (with nut) being passed through the splice bars and a rail between the cross tie 9 and the ends of the splice bars and one or more (two are shown) splice bolts and nuts 8 being employed between the cross tie 9 and a. rail end. The splice bar 3 has a small ridge 3 below the flange 5 :the head of the splice bolt 8 contacts with this ridge and is thereby prevented from turning when the nut is being screwed on or off the bolt. 11' is a tension or tie member, which is,preferably, of angle section,

,plain'or bulb, and connects the cross ties at a splice together. The splice bars 3, a are bolted to the cross ties 9 at the opposite sides of the line or surfaces of contact of the rails 1, 2, a splice bar 3 being secured to the cross tie 9 by coach screws 12 which are inclined to the vertical so that their heads may seat squarely on the upper and sloping faces of the parts 7 of the flange 7 and a splice bar a being secured to the cross tie 9 by bolts 18 passing through the part 7 of the flange 7,

the soleplate 10, the cross tie 9 and the member 11. The bolts 13 are arranged vertically, the portionv of the part 7 of the flange with which the nut 13 contacts being shaped to provide a horizontal seating therefor. The splice ba-rA: has an upward extension 14 above the flange 5: this upward extension 14 extends the full length of the splice bar and has a lateral flange 15, the upper surface of which is about level with the uppersurfaces of the rail heads 6. The ends of the flange 15 have their outside corners turned down as at 16. The lower flanges 7 and the top flanges 5, 15 increase the moment of inertia of the splice bars 3,411; the tie or tension member 11 through their attachment through the splice bars to the rails prevent creeping; and the complete arrangement of parts provides for a more rigid splice than is ordinarily obtained, thereby preventing hammering and undue wear of rail ends.

What I claim is:

Means for joining rails of bull-headed or flat bottomed section together comprising, in combination, fish plates each comprising a web portion having flanges along its top and lower portions, the upper flange being shaped to seat on the underside of the rail head and the lower flange being horizontal at its end portions and merging into a more or less vertical member, a sleeper on each side of the joint, and tie or tension members connecting the sleepers together at each joint, the fishplates, sleepers and tie or tension members being all bolted together.
