METALLIC BEAM SPLICE.

Application filed February 9, 1923.

T iiZZ whom it may concern c it known that I, JOHN MAYOT'IE, a citizen of the United States, and resident of (.ldanah, in the county of Ashland and State of lVisconsin, have invented certain new and useful Improvements in Metallic Beam Splices; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to metallic beam splices, and is particularly directed to a splice applicable to building beam or building structure joints, to rail connections for tracks and for similar purposes.

Objects of this invention are to provide a metallic beam splice which has a double lock joint which will continue to hold the beam or rails from relative turning motion, although the bolts and fish-plates may have become detached.

Further objects are to provide a metallic beam splice which is so constructed that one beam end may not be lifted directly upwardly from the other, although the attaching bolts may have become removed, which will prevent spreading of rails, and which is still, self sup-porting and strong.

Although the invention is applicable to several diiierent uses, it has been illustrated in the accompanying drawings as applied to a rail joint, and in such drawings- Figure 1 is a side elevation of the joint.

Figure 2 is a plan view of the structure shown in Figure 1.

Figure 3 is a section on the line 33 of Figure 2.

Figure 4 is a plan view of one of the rail ends.

Figure 5 is a ing rail end.

Referring more particularly to the drawings, it will be seen that a pair of rail ends have been illustrated, such rails comprising a web 1, a base or flange 2, and a head 3. For convenience of description, the corresponding portions of the right hand rail in Figure 1, have been indicated 1, 2 and 3, respectively. These rails are arranged with their ends juxtaposed, and are cut away, as indicated in Figures d and 5. One of the rails, for instance the left hand, has its web 1 cut out, and the one side of the head 3 cut away, thereby leaving a projecting tongue 41. The flange 2, is similarly plan view of the cooperat- Serial No. 617,961.

The corresponding end of the has its web 1 left intact. However, a portion of the head is cut away thereby leaving a projecting portion 6 integrally joined to the web and extending only to one side thereof. The flange is similarly cut away on the opposite side of the web,

thereby leaving a projecting portion 7 integrally joined to the web and extending therefrom in an opposite direction of the portion 6, a

In assembling the rails,

It is, therefore, to be understood that al- 7 though one form of the invention has been described in considerable detail, the invention may take other forms and is to be limited only as defined in the appended claims It is further to be understood that the. term beam, as used in these claims, is to be understood as covering the usual beam construction, railway rails, and other similar articles.

I claim:

1. In a beam splice, the combination of a pair of juxtaposed beam ends having interlocking tongues positioned upon opposite sides of a central web, a pair of fishplates bolted through such web, one of said ends having the web wholly cut away adj acent s ch end and the other end having a web adapted to fit within the cut away portion.

2. In a metallic beam splice, the combination of a pair of juxtaposed beam ends each having a head, a web, and a lower flange, each of said ends having a tongue forming a continuation of said head and flange respectively, and said head and flange being cut out adjacent said tongues to receive the corresponding tongues of the other beam end, one of said rail ends havingthe web cut away adjacent the tongue, and the other 01 said ends having the web in position adjacent its tongue and integrally joined therer to, whereby said ends may be interlocked to form a substantially continuous head and flange adjacent said tongues, and a pair of fish plates bolted through the webs of the adjacent rail ends.

In testimony that I claim the foregoing I have hereunto set my hand at Odanah, in the county of Ashland and State of Wisconsin. 7

JOHN MAYOTTE.
