UNITED STATES PATENT OFFICE.

HARVEY CUDDY AND CHARLES LEWIS, 0F WINCHESTER, KENTUCKY, ASSIGNORS', BY DIRECT AND MESNE ASSIGNMENTS, TO CUDDY-LEVJIS INTER-LOCKING RAIL JOINT CORPORATION, OF WINCHESTER, KENTUCKY, A CORPORATION OF KENTUCKY.

RAIL JOINT.

Application filed September 20, 1927. Serial No. 220,748.

This invention relates .to improvements in rail joints and has for an object the provision of a simple and efficient joint by means 'of which the meeting ends of adjacent rail sections may be connected without the use of connecting bars, and with a minimum number of bolts.

Another object of the invention is the provision of a joint wherein the meeting ends are shaped and interlocked so as to prevent relative longitudinal and pivotal movement of the rail sections, the function of the bolts being only to prevent relative lateral movement, so that the said bolts are subjected to very littlestrain.

Another object of the invention is the provision of a joint wherein the meeting ends overlap, so that the wheels of a. car will pass upon one rail section before leaving another, and pounding at the rail joint will thus be obviated.

With the above and other objects in view,

the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illus trated in the accompanying drawing and pointed out in the appended claim.

In the drawing Figure l is a side view of a rail joint constructed in accordance with the invention.

Figure 2 is a top plan View.

Figure 3 is an enlarged section on, the line 33 of Figure 2.

- Referring to the drawing in detail where in like characters of reference denote corresponding parts, the reference character R indicates adjacent rail sections, the meeting ends of which are longitudinally reduced and are adapted to overlap. The end of each section R is provided with a head 10 which is of less cross sectional area than that of the rail and is connected to the body of the rail by a neck 11. The cross sectional area. of the neck is less than that of the head, the inner walls 12 and 13 of the head an'dneok respectively being perpendicular as shown in Figure 3. The reduced neck also provides spaced parallel perpendicular shoulders 14 and 15, the shoulders 15 abutting the outer ends of the heads 10 which are also perpendicular or squared.

By reference to Figure 2 of the drawings it will be seen that the heads 10 are received within spaces provided by the necks 11, the shoulders 14 and 15 of one section engaging the shoulder' and the outer squared end of the head of the other section so that an interlocking connection is provided which will prevent relative longitudinal movement of the rail sections and also prevent pivotal movement.

The overlapped ends of the rail sections are connected by means of bolts 16,the lat ter acting to prevent relative lateral movement of the sections. By means of this connection between the rail sections, only two bolts are necessary to securely hold the sections together and these bolts are relieved of all shearing strain due to the interlocking connection between the rail sections.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.

Having described the invention what is claimed is z.

A rail. joint comprising adjacent rail sec tions each having itsmeeting end longitudinally reduced to provide a head having a squared outer end, a neck of lesser cross sectional area than the head and'joining' said head to the body of the rail section and providing vertically disposed spaced parallel shoulders extending transversel and throughout the height of the rail, whereby the headof one rail section may be received between the shoulders of another rail section with the shoulders and squared outer ends of the sections abutting to prevent relative pivotal. and longitudinal movement; and bolts extending through the rail sections to prevent relative lateral movement of said sections.

In testimony whereof we ailix our signatures.

HARVEY CUDDY.
