RAIL JOINT.

APPLICATION FILED MAR.4, 1908 GEORGE ELY, OF MONTPELIER, INDIANA.

RAIL-JOINT.

Specification of Letters Patent.

Patented July 14,1908.

Application filed March 4, 1908. Serial No. 419,072.

To all whom it may concern:

Be it known that I, GEORGE ELY, citizen of the United States, residing at Montpelier, in the county of Blackford and State of Indiana, have invented certain new and useful. Improvements in Rail-Joints, of which the following is a specification.

The present invention is designed to stiffen and strengthen the joint formed between adj acent sections or ends of rails used in the construction of railroads, so that the jolt usually experienced when passing over a joint is overcome wholly or in part, the meeting ends of the rail sections interlocking so as to'provide in effect a continuous upbearing surface for the wheels of the rolling stock.

The present invention contemplates the interposition of web blocks, or bridge pieces, between adjacent rail ends or sections, said web blocks interlocking with the rail sections both at their upper and lower ends so as to prevent possible lateral displacement and insure a continuous surface for the car wheels.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which:

Figure 1 is a perspective view of a rail joint embodying the invention. Fi 2 is a perspective view of the rail joint, the parts being separated. Fig. 3 is a perspective view of a rail section or end inverted.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The extremities of the rail ends or sections 1 are similarly formed, each being provided in its head with a mortise 2 and in its foot with a mortise 3. The mortise 2'is open at one end and at the top and is of rectangular formation. The mortise 3 is open at one end and at the bottom and is of triangular form, the apex of the mortise being uppermost when the rail is in normal position. The triangular form of mortise 3 permits the provision of an interlocking jointof maximum strength Without appreciably weakening the foot of the rail end or section. The rectangular form of mortise 2 is best adapted for the head of the rail section and permits an interlocking joint of maximum strength bemg secured without materially weakening the head.

Theweb block or bridge piece 4 corresponds in outline to a transverse section of a rail section so as to come 'fiush therewith. The web block is provided at each end with tongues or projections 5 and 6. The tongues or rojections 5 extend from the head of the we% block, whereas the tongues or projections 6 extend from the foot thereof. 1 The tongues or projections 5 are of a size to snugly fit the mortise 2. The tongues or projections 6 are of triangular form and snugly fit the mortise 3. The tongues or projections 5 overlap the joints formed between the rail sections'and the web block and support the car wheels when passing over the joint, thereby preventing any jar or jolt. The web blocks or bridge pieces are comparatively short and result in the provision of a double joint for compensating for con traction and expansion, thereby preventing the formation of a large gap, such as usually results Where a single joint only is provided between adjacent rail ends or sections.

When the parts are assembled, the joint is strengthened by means of fish plates 7 which extend along opposite sides of the web portions of the rail sections and web block and which are bolted to the rail sections in the usual manner, the web portions of the rail sections being slotted to receive the connecting bolts so as to allow for contraction and expansion.

Having thus described the invention, what is claimed as new is:

In a rail joint, the combination of rail sections, each having mortises in its head and foot, the mortises in the heads of the rail sections being of rectangular formation, and 0 en at one end and at the top, and those in t e foot portions of said rail sections being of triangular form and open at one end and at the bottom, and a web block corresponding in outline to a transverse section of a rail section and fitted between the said rail sections and having at each end upper and lower In testimony whereof I ail'lix my signature torlrguis, the upperltorgueils being of recta1n in presence of two witnesses.

u ar orm to snug t t e Inortises in tre 1 T l leads 0f the rail sl ections, and the lower GEORGE 5 tongues being of triangular form to fit the tri- Vitnesses:

angular mortises in the foot portions of said V. B. HILLYARD, rail sections. FREDERICK W. BAINES.
