RAILWAY-RAIL.

SPECIFICATION forming part of Letters Patent No. 794,719, dated July 18, 1905.

Application filed August 15, 1904. Serial No. 220,702.

To all whom it may concern:

Be it known that I, EMIL F. KRELL, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Railway-Rails; and I declare the following to be a full, clear, and exact description-of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in railway-rails, shown in the drawings, and more particularly set forth in the following specification and claims.

In the drawings, Figure 1 is a plan View showing a portion of the rail embedded in the street-pavement, also the rail, partly in section, with the paving-blocks removed. Fig. 2 is a cross-sectional view through the track and concrete foundation with parts broken away. Fig. 3 is a plan view showing a variation in the form of the bracket-braces employed. Fig. 4: is a perspective view of the form shown in Fig. 8. Fig. 5 is a perspective view of the spreaders or tie-plates. Fig. 6 is a perspective view of the shoe employed to receive the webs of the abutting rails. Fig. 7 is a, cross-sectional view through the rail and supporting-shoe of the form shown in Figs. 4 and 6. Fig. 8 is a cross-sectional view of a variation. Figs. 9, 10, 11 are similar cross-sectional views of other variations. Fig. 12 is asection and elevation of the nuts engaging the anchorbolts. Fig. 13 is a cross-sectional view of the rail, showing another modification.

The object of my invention is to construct a rail for street-railway purposes having a relatively wide web projecting down ward into the concrete foundation and provided with relatively broad projecting flanges secured to the web of the rail and adapted to rest on the surface of the foundation, whereby the load will be brought directly upon the same, dispensing with the usual cross-ties.

Another object of my invention is to dispense with all projecting flanges or parts which ordinarily engage under the concrete foundation, making it necessary to remove the overlying concrete before the track can be raised or removed for repairs by providing the rail with a broad depending web, which may taper, but is preferably of a uniform thickness, adapted to enter the foundation to a sufficient depth to give strength to the rail and afford the necessary resistance against the bedded in the foundation.

It will be seen by this construction that if necessary to level up the track it may be raised to the required altitude and suflicient concrete forced under the flanges to level it with the contiguous road-bed without disturbing the foundation. It will also be seen that while concrete of suflicient depth should be laid under the rails to support and receive the depending web and to support the load there is no necessity of carrying it the same depth from rail to rail, as there are no supportingties to be embedded, thereby eflecting a great saving in the cost of construction.

By my construction the fish-plates ordinarily employed are dispensed with, as the loadsupporting flanges secured to the web are arranged to overlap the abutting rail on one side, through which the end of the abutting rail is secured by the usual bolts, doing away with the usual fish-plates.

Other advantages and improvements will be apparent on a further reference to the speciflcation.

Referring to the letters of reference shown in the drawings, A is a rail, provided with a depending web A, projecting downward and embedded in the concrete foundation B.

C represents flanges, which may be formed integral with the web A of the rail or they may be bolted or otherwise secured thereto. These flanges are relatively broad and when resting on the foundation are of suflicient strength to carry the load.

D represents brackets bolted to the flangesand to the web of the rail and are designed to stiffen and brace both the flange and the rail. These brackets may be formed, as shown in Fig. 1, with an outside web or may be pressed spreading or shifting of the rails when e'ni--- or cast with a middle brace in the form shown foundation, the upper ends engaging the flanges C.

6 represents closed nuts shown in Fig. 12, engaging the ends of the anchor-bolts and are of suflicient length to admit of any probable adjustment and to retain a suitable lubricant to prevent the nuts and heads of bolts from rusting.

F represents spreaders or tie-plates preferably formed of channel-iron and bolted or otherwise secured to the flanges (3. These spreaders are placed at suitable intervals to line up and hold the track in position while the concrete is being filled in around the web of the rails and to,assist in supporting the load carried by the rails.

Gr represents brick or other surface material to level the roadway with the tread of the rai 4 a H represents shoes bolted to the flanges G and having channels to receive the web of the abutting rails.

It will be seen by reference to Figs. 1 and 3 that one of the flanges C is made to overlap the web of the abutting rail, the opposite flange of the abutting rail occupying the same position to thatjust mentioned. By this arrangement the ordinary fish-plate is dispensed with, as the flanges overlap the joint in the rails and serve the purpose of fish-plates.

By my construction when it becomes necessary to repair the track the rails may be raised slightly, if desired, without disturbing anything but the surface brick or material, as there is no projecting web or flange to engage the foundation, and additional concrete may be easily forced under the flanges to level the rail with the adjacent track and road.

lNhile I have shown a number of modifications of supporting-flanges, which in each case are designed to rest upon the foundation, I do not wish it to be understood thatIin any way limit myself to any or to the different forms suggested, as the point and manner of engaging the flanges and their exact locations on the web are entirely immaterial, except as they serve to support the rail by resting on the foundation.

In Fig. 13 is shown a modification in which a shoulder a is formed beneath the tread of the rail against which the edge of the flanges abut to receive the load.

to rest upon a suitable foundation, a depende ing web of substantially uniform thickness projecting below said flanges to be embedded in the foundation and suitable bracket-braces secured to the web of the rail and to the projecting flanges to stiffen the parts, substantially as described.

2. In a track for street-railways, a railwayrail having projecting flanges to rest upon a suitable foundation, and also provided with a depending web projecting downward from beneath said flanges to be embedded in the foundation, the foundation, and anchor-bolts embedded in the foundation and engaging the flanges of the rails, substantially as described.

3. A railway-rail having a depending web of substantially uniform thickness, for embedding in a suitable foundation, in combination with projecting flanges secured to each side of the web of the rail, the flange on one side of the web projecting beyond the end of the rail and the flange on the opposite side of the web terminating a corresponding distance from the end of the rail, both the projecting flange and the web adjacent to its end being provided with apertures by which it is engaged with abutting rails, substantially as described.

4:. A railway-rail having a depending web of substantially uniform thickness to be embedded in a suitable foundation in combination with projecting flanges secured to each side of the web of the rail, the flange on one side of the web projecting beyond the end of the rail and the flange on the opposite side of the web terminating a corresponding distance from the end of the rail, both the projecting flange and the web adjacent to its end being provided with apertures by which it 'is engaged with the abutting rails, and a shoe secured to the flange, forming a channel to receive the ends of the depending webs of the abutting rails, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.

EMIL F. KRELL.
