RAILROAD-RAIL.

SPECIFICATION forming part of Letters Patent No. 763,992, dated July 5, 1904.

Application filed July 2, 1903. Serial No. 163,991. (No model.)

To all whom it may concern:

Be it known that I, J AMES MANDER, a-citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Railroad-Rails, of which the following is a specification.

My invention relates to a new and useful improvement in railroad-rails, and has for its object to so construct a railroad-rail that the track will be practically continuous without any joint extending entirely laterally across the rail and doing away with fish-plates.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referringto theaccompanying drawings,forming a part of this specification, in which Figure 1 is a perspective view of my improved railroad-rail, showing the manner in which the joints are made; Fig. 2, a crosssection through my improved railroad-rail, showing the webs compressed; Fig. 3, a side elevation of the same.

My improvement consists in providing railroad-rails made in halves, the rail being divided longitudinally and vertically. The two halves of the rail, as represented by A, are placed together, so that the ends of two sections upon one side will come together at a point intermediate of a section upon the other side. Thus the rail will not be divided laterally entirely across at any one point. The halves of the rail are secured together by bolts B passing through the webs, and the holes C, formed through the webs, are oblong in a longitudinal direction, so as to allow for expansion and contraction of the rails. The inside faces of the halves of the rail are slightly concaved, as represented at D, so that the two halves of the rail only meet at the top and bottom. Thus as the rails wear the two halves can be brought together by the bolts and always make a good contact upon the tread of the rails, and the two halves of the rail are separated slightly at the center, which will allow for a spring in the rail, which is beneficial.

The advantage of my improved rail is that the rail can be rolled easily the same as the ordinary railroad-rail and can be laid much more quickly, on account of the absence of fish-plates, and if any section of the rail becomes damaged it can be easily and quickly removed and a new one substituted, and on account of the absence of joints entirely across the rail the trains running upon the rails will run smooth and not be jarred at each joint, as in ordinary rails.

Of course I do not wish to be limited to the exact construction here shown, as slight modifications could be made without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is In a rail-joint, the combination with the meeting ends of a rail, each of said rails having their overlapping surfaces concaved from the top of the heads to the bottom of the base, the webs and flanges being. in such relation that when the webs are compressed, the baseflanges will lie on a horizontal plane.

In testimony whereof I have hereunto affixed my signature in the presence of two witnesses.

JAMES MANDER.
