ANDREW PERNULA, OF ONEIDA, WASHINGTON.

RAIL-JOINT.

1 JAGAAA.

Application filed. January 21, 1915.

To all whom it may concern Be it known that 1, ANDREW PERNULA, a citizen of the Grand Duchy of Finland, residing at Oneida, in the county of Wahkiakum and State of Washington, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specification.

This invention relates to rail joints, and more particularly to that class of rail joints in which the meeting ends of the rails are provided with tongues and slots respectively, the tongues of one rail adapted to enter the slots of the other rail and be secured therein to provide a smooth joint.

An object of the invention resides in the provision of a rail joint of this character, the meeting ends of the rails being prevented from relatively vertical movement, thus etfectuallv preventing pounding of the wheels of the rolling stock which passes thereover.

Another object is to provide a joint which is simple in construction, thoroughly reliable and eificient in its operation, and cheap and easy to manufacture.

With these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, and claimed.

In the drawings :Figure 1 is a side elevation; Fig. 2 is a top plan view; Fig. 3 is a perspective view showing the respective rails separated; and Fig. A is a plan view showing the formation of the respective ends of a rail.

Referring to the drawings by numerals, 1 designates the base, 2 the web and 3 the head of the rails. One end of the rail has its end thickened and cut away to provide an offset extension A, and a recess 5, the recess extending into the head of the rail and base flange as shown at 6 and 7 respectively. The recess 5 terminates adjacent the end of the rail, and formed on the web 2 and overlying the recess, is a web 8, the tongue 9, which is Specification of Letters Patent.

Serial No. 3,568.

formed on the other rail end being adapted to enter the recess with its end resting within the portion of the recess overhung by the web 8.

In order to provide a smooth joint between the heads of the rails, the ends of the head may be cut away or made diagonal as shown clearly in Fig. 2 of the drawings.

Upon reference to Fig. A of the drawings it will be noted that one end of each of the rails is formed with the extension and recess, while the opposite end has the head and base flange terminating short of the end of the web, thus providing the extension 9 for engagement with the recess of the next rail. After the rails have been moved together a bolt 10 is passed through openings in the extension A and web of the co-acting rail in order to prevent accidental disengagement of one rail from the other.

From the foregoing description taken in connection with the accompanying drawings it is thought that the construction and operation of the device will be clearly understood and while I have herein shown and described one specific form of my invention 1 do not wish to be limited thereto, except for such limitations as the claim may import.

What is claimed is The combination with a rail having its web thickened and cut away to provide an extension, and a recess, the end of the head being cut away on a diagonal line, said recess extending into the head and base of the rail, said web being provided with an off-set portion extending from the upper extremity thereof and at right angles thereto, a second rail having a tongue formed thereon for engagement with said recess, said oifset portion engaging said tongue during the insertion thereof, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ANDRE? PERNULA.
