MORTISE JOINT.

Application filed January 25, 1927; Serial No. 163,343.

Our invention relates to improvements in rail joints and it consists in the combinations, constructions, and arrangements hereinafter described and claimed.

An object of our invention is to provide a rail joint in which the adjacent rail sections are cut on a bias or are mitered and in which the thin portions of the cut rail section are re-inforced by portions which also extend beneath the head of the adjacent rail section for supporting the latter.

A further object of our invention is to provide a device of the type described in which the supporting projection cooperates with the angle bar on the opposite side of the ra l for preventing a lateral movement of one rail section with respect to another railsection.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

Our invention is illustrated inthe accompanying drawing forming a part of this application in which,

Figure 1 is a perspective view of the device and Figure 2 is a horizontal section through the device.

In carrying out our invention we provide rail sections A and B each having a head 1, a web 2, and a flange 8. Since each rail section A and B is identical with the other, a description of one will suffice for both.

It will be noted that the rail section B has an inclined cut 4, a shoulder 5 and stub end 6. The portion of the rail adjacent to the end 6 is built up as at 7 for providing a support for the head 1. It will further be noted from Figure 1 that the portion 7 projects a short distance beneath the headl of the adjacent rail section. In this way the part indicated at 8 is prevented from being bent downwardly by the car wheels as would be the case if it were not for the portion 7. The portion 7 cooperates with the angle bar 9 in supporting the rail head 1 and in securing the two rail sections together. The drawing clearly shows how the angle bar 9 abuts the edge 10 of the portion 7, and bears against the underside of the rail head 1.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The rail sections are prevented from lateral movement with respect to each other by the portions 7, and

each bears against the underside of the rail head 1.

It will be noted from Figure 2 that the portions 7 have openings therein for receiving bolts 11, these bolts being also secured each to one of the angle-bars 9. In this way the portions 7 and the angle bars 9 act as a brace or a clamp at the point X. The angle bars are provided with openings 12 for receiving bolts 13. The openings 14 in the rail sections are large enough to permit a slight play between the rail sections thus allowing for expansion and contraction of the sections 8 due to changes in temperature.

It will be seen from the construction as described, that the mitere'd' joints between the rail sections will prevent the usual clicking of the wheels as they pass over the section.

At the same time,however, the rail sections are not weakened by such a construction due to the special arrangement of the portions 7 and the angle bars 9.

We claim:

1. A device of the type described, comprising two rail sections having mitered ends, reinforcing means for the rail heads disposed at the ends of said sections and being integral withsaid sections, angle bars cooperating with said reinforcing portions for preventing latoral movement of said rail sections with respect to each other, said angle bars also aiding in reinforcing the heads of said sections.

2. A device of the type described, comprising two rail sections having mitered ends, said sections having integral portions at the ends thereof for supporting the rail heads, said portions extending beneath the rail heads of adjacent sections for reinforcing the latter, and angle bars cooperating withsaid portions for preventing lateral movement of said rail sectionswith respect to each other and for reinforcing the rail heads.

3. A device of the type described comprising two rail sections, each section having a head, a web, and a base portion, said sections 10 having mitered ends; a reinforcing block formed on the web of each section at the end thereof and extending below the head of the adjacent section, the outside face of said block being at a level with the side of the head 1 angle bars cooperating with said reinforcing blocks for preventing lateral movement of said sections with respect to each other.

4:. A device of the type described comprising two rail sections, each section having a I disposed adjacent to said block, said blocks and said angle bars having apertures therein so disposed as to allow the connection of the 7 block of one sect-ion with the angle bar of the 10 other section.

In testimony whereof We afiix our signatures;

CHARLES E. SKAGGS.
