2 Claims. (Ci. 233-230) The invention 'relates to improvements in rail joints as described in the present specication and illustrated in the accompanying drawing that forms a part of same.

The invention consists essentially in the shape and arrangement of the rail ends forming the joint as pointed out broadly and specically in the claims for novelty following a description containing an explanation in detail of an acceptable form of the invention.

The objects of the invention are to devise a means whereby perfect arrangement for the expension and contraction of the rail joints will be assured; to facilitate the laying and maintenance of rail tracks and save time and labour in the joining of the rail ends to one another; to construct a rail joint capable of withstanding heavy pressure and so formed and joined and secured together that it will minimize danger of any displacement of the rail ends and consequently avoid the possibility of accidents to the railway cars using such tracks; and generally to provide a rail joint that will be comparatively inexpensive to manufacture and applicable to various types of rails and emcient :for its purpose.

In the drawing, Figure i is a fragmentary plan view of the rail joint.

Figure 2 is a fragmentary side elevation of the rail joint having the fish plate removed.

Figure 3 is a vertical sectional view as taken on the lines 3--3 in Figure 2.

Figure 4 is a fragmentary side elevation of the rail joint.

Figure 5 is a vertical sectional view as taken on the lines 5-5 in Figure 4.

Figure 5 is-an enlarged fragmentary perspective view o f one of the rail ends forming the female member.

Figure-7 is an enlarged fragmentary perspective view of one of the rail ends forming the male member.

e and illustrates a conventional flat bottom type j Figure 8 is a vertical sectional view as taken on the lines 8-8 in Figure 2.

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawing, the railway rails as indicated by the numerals it and ii may be formed in the usual conventional type; that is to say the rails may be provided with the rail heads li and i3 and the flat bottom rail bases Ill and i5, or may be in the form of plate rails, ledge rails, bridge rails, double headed rails or bull.

tion. and the accompanying drawing describes 55l of rail.

These railswhich are hereinafter called rail sections are each provided at their outer ends with specially constructed rail ends to enable the proper joint when the sections abut one another lfor fastening them together.

Each rail section may be provided at one end with a female member and at the other end with a male member, these members of course being integral with the sections, in other words, the rail ends are cut out and shaped to form the members and in the assembly of the rails one section will have the male member abutting and se cured to the female member of the adjacent rail section.

The female member i6 is formed with an upper longitudinal recessed portion il and this recessed portion extends inwardly for a predetermined length and forms a supporting surface it and an abutting surface i9, the latter surface being vertical and merging with the rail head i2, the latter being diagonally cutout to expose the recessed portion from above and forming projecting lips 2li and 2i which extend outwardly for a predetermined distance and at a diagonal position with respect to the side edge of the recessed porm tion. In the formation of the projecting lips a fiat ledge 22 is formed and the purposeior which will be hereinafter more particularly described..

The male member 23 is provided with a lower longitudinal recessed portion 21% which is formed by cutting off the portion of the rail base lli and the lower portion of the rail section i0 and in that way a projection portion 25 is constructed and is located beneath and merges with the rail head i3 which is diagonally cut to form tapering walls 26 and 2l merging with the vertical outer surfaces 28 of the rail head and forming projecting

lips

29 and 30 and a at horizontal ledge 3i.

The rail ends of the rail sections are provided with

elongated slots

32 and 33 for the introduction of the fastening members 3e that are utilized for securing the iish plates 35 and 3S.

In the actual joining of these various rail sections to one another to form the trackway one rail section is secured to the road bed in the usual `manner and the other rail section which is to be joined with the aforementioned section is simply slid into position by having the male member engage with the female member in such a way that the recessed portion of the members, the projecting lips and the horizontal ledges will co-operate with one another to complete the joint. The sh plates are then applied for securing the rail ends together and-fastening members hold the rail ends and ish plates together and this completes the rail joint. l

What I claim is: s l

1. In a rail joint. a pair of rails each having a basea web, and a head, said head being cut vertically and diagonally from edge to edge for a portion of its thickness, the entire remaining thickness at one side of said web being undercut to form a recessed lip, and the entire remaining thickness at the other side of said web being projected to form a projecting lip, said lips having surfaces parallel to the diagonal cut and at opposite sides thereof, said heads being shaped reversely or compiementarily .of each other, whereby the projecting lip of each head abuts the recessed lip of the other head.

2. In a rail joint, a pair of rails each having a base, a web, and a head, each head being out vertically and diagonally from edge to edge and from its upper surface for a portion of its thickness, the entire remaining thickness at one side of said web being undercut to form a recessed lip, and the entire remaining thickness at the other side of said web being projected to form a projecting lip, said lips having surfaces parallel to the diagonal cut and at opposite sides thereof, one of said webs being notched adjacent to its base and the other adjacent to its head to form a staggered joint, said heads being shaped reversely or complementarily of each other, whereby the projecting lip of each head abuts the recessed lip of the other head.
