RAILROAD-"RAH...

Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed May 8, 1905. Serial No. 259,364

To all whom, it may concern.-

Be it known that I, CONRAD F. GRAIT, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented a new and useful Improvement in Railroad- Rails, of which the following is a specification.

This invention relates to a rail in which a base and a tread section are employed, the two overlapping.

The object of the invention is a rail in which the tread-section when worn or broken can be readily replaced without replacing the complete rail, the new tread being set in po section upon the old base.

Another object is a rail in whic the u e of nuts and the usual form of iisl1-plates is avoided.

The invention consists in the novel features of construction hereinafter described, shown in the accompanying drawings, and pointed out in the claims.

In the drawings, Figure 1 is a perspective view of my rail, one base section being broken off. Fig. 2 is a perspectiveview of an end portion of a base-section. Fig. 3 is an inverted perspective view of a portion of a tread-section, showing a tie-block in place and also inverted. Fig. 4 is a perspective view of the tie-plates used in connection with block. Fig. 5 is a perspective view of a In the drawings, A represents the base-section of the complete rail, and B the treadsection. Hereinafter these parts will be referred to simply as the base and tread. The base is grooved along its upper face, as shown at A. At each end the base is cut away, as shown at A and recesses are formed in the sides adjacent the ends, as at A". Perforations A are formed in the sides of the base above the bottom of the groove A for the passage of bolts C.

The tread B has a central depending web B, perforated for passage of the bolts C, as shown at B and the tread A also carries on each side depending flanges B, which fit over the sides of the base A, the web B fitting in the grooves A of the bases, as it will be understood that in assembling the rail the tread and base break joints. A block D is bifurcated to straddle the web B of the tread and is reduced. in. thickness adjacent its longituninal center by being cut away on the sides,

as shown at D. The blocks D rest on the base A adjacent each end of the base and in the cut-out portions A the cut-away portions D of the blocks alining with the recesses A of the base. plates, fit in the cut-away portions of the blocks and in the recesses A of the base, one end of each plate resting in a recess A of one base and the other end. of the block in a similar recess in the adjacent base. One plate E of each pair carries on its inner face an integral pin E, which passes through a suitable perforation in the block D and through an alining perforation in the other or opposing plate of t 1e pair and is locked in position by a cotter- )in E The bolts C after being placed in posltion have one end angled or bent, as shown at C in Fig. 5. 7

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A rail comprising overlapping tread and base sections, the base-sections being cut out at the ends and recessed on the sides, a block fitting said cut-out portions and recessed on the sides, plates fitting said recesses, each plate overlapping the block, and means for locking the plates in position.

2. A rail comprising a tread having a depending web, a base longitudinally grooved to receive the web, said base being recessed on each side adjacent the ends, a block adapted to fit between two base-sections, and recessed on the sides, said block being bifurcated to straddle the web, and tie-plates fitting in the recesses of the bases and block.

3. A rail of the kind described comprising a tread portion having a depending web and depending side flanges, a base cut away at each end and grooved to receive theweb, said base and tread having alining perforations, a bolt adapted to pass through said perforations, a block adapted to fit in the cut-out portions of adjoining bases, said block and bases having alining recesses, a tie-plate adapted to fit said recesses and having an integral pin adapted to pass through the block, an opposing tie-plate perforated for the passage of the pin, and means for locking the pin in place.
