RAIL.

- Specification of Letters Patent.

Patented May 18, 1920.

- Application filed July 5, 19.18. Serial No. 24332152.

To all whom itmag concern:

Be it known that I, WALTER McCLuNArIAN, a citizen of the United States, residing at the city and county oi-San Francisco and State of California, have invented new and useful Improvements: in Balls, of which the following is a specification.

This invention relates to. a rail, and particularly to a reinforced concrete metal covered rail.

One of the objects of the present invention is. to provide a reinforced concrete rail for ordinary train service and the; like, the weight of which inay be considerably reduced when compared with "the standard steel rail, while the cross sectional, strength is materially increased.

Anotherobject of, the, invention is to provide a concrete rail, which is inclosedby a steel shell to provide a durable; wearing surface, and to protect the concrete, and furthermore to provide a reinforced rail of the character described a in which the actual amount of steel employedis small when com-.

pared with an ordinary steel rail.

Further objects will hereinafter appear.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings in which--- Figure 1 is a perspective view of the rail.

Fig. 2 is a cross section on line 2-2, Fig. l.

- Fig. 3 is a cross section on line 33, Fig 1, showing the modified form of filler within the rail.

Fig. 4 is. a cross section on line 4-4, Fig. 1. V

Fig. 5 is a longitudinaland vertical section on line 5-5, Fig. 1.

Referring to the drawings in detail, A in dicates in general the rail forming the subject matter of the present invention. The rail consists of a steel-shell having a cross section substantially such as shown. This shell may be formed by rolling the steel, or in any other suitable manner, and it consists of a head member 2, a pair of side webs 3 and inturned bottom flanges i. The rail is furthermore provided with end blocks 5, which serve the purpose of strengthening the rails at the ends, and also of securing the concrete against endwise removal. The blocks 5 are also constructed of steel, and are preferably secured within the metal shell by being electrically welded,,or by any other suitable means. The rail. thus constructed may be filled with any suitable filler, but preferably concrete such as shown at 6, which is reinforced by longitudinally extending rods or like means such as shown at 7. The rail thus constructed may be supported upon concrete ties or wooden ties. In either instance it is, however, necessary to secure the rail by means of bracket plates 8 placed on opposite sides of the rail. These brackets may be secured in any suitable manner, but preferably by bolts 9 extending through the side webs 3 of the rail, the base portion of each bracket being provided with openings 10 for the reception of bolts ifconcrete ties are employed, or to. permit the driving of spikes if wooden ties are em-. ployed. by means of fish plates 11 constructedsubstantially as shown in Figs. 1 and l, that is, the fish plates are rigidly bolted to the rails by means of side flanges 11 and are reinforced and strengthened by bottom, flanges 12 extending under. the metal housing or flanges l of the rail.

The spacing between the brackets 8 by which the rails are secured to the; ties may be such as local conditions may require.

By referring to the several figures it will be seen that shoulder 16 is formed 011 each side of the head member 2. This shoulder extends from end toend of the rail and engages the upper end of the brackets 8. The head is in this manner partly supported by said brackets, and is, therefore, not only reinforced, but the cross sectional strength of the rail is materially increased.

I similarly wish it understood that the materials and finish of the several parts forming the rail and the brackets may be such as the experience and the judgment or the manufacturer may dictate.

By referring to Fig. 8 it will be seen that a fiber or wooden fillerl is placed in the head of the rail, while reinforced concrete is employed in the base. This type of filler may be of considerable importance where tl e rail is subjected to heavy traliic, as. the

constant vibration and pounding on the head of the rail might have a detrimental effect on the rail if concrete were solely mployed.

A rail constructed as shown in the seve figures is very much lighter than an ordinary steel rail of the same size, due to the met that the quantity of steel employed is The rails are otherwise connected very small. The cross sectional strength of the rail is, however, comparatively greater; the actual cost of the rail is therefore very much less, and freighting and labor charges are correspondingly reduced. The steel blocks 5 placed at the ends of the rails are of considerable importance, first, because they eliminate the necessity of placing end blocks against the rails when the concrete is being poured, and, secondly, because they strengthen the rails at their weakest points, that is, as a perfect joint between rails is practically impossible to maintain, the car wheels when passing over the rail joints, therefore, have a tendency to hammer the rail ends; these may, therefore, be termed the weak points of the rails. They are, however, in this instance enormously strengthened by end blocks, which may extend inwardly any distance desired, thereby relieving the concrete of the heaviest pounding to which the rails are subjected.

While concrete and a wood filler have here been described, I wish it understood that any other suitable filler may be employed without departing from the spirit of the present invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A rail comprising a hollow head, a pair of web members, said webs supporting the head and formed integral therewith, and also forming a base for the rail, a non-metallic filler for the rail and transverse closures at the ends of each rail section.

2. A rail comprising a hollow head, a pair of web members formed integral therewith and also forming a base for the rail, a concrete filler for said webs and head, and bracket plates fitting the web sides and having their upper edges engaging and supporting the shoulders on the rail head.

3. A rail comprising a hollow metal shell forming a head and a pair of web members,

a concrete filler for the hollow shell, and a resilient filler interposed between the concrete filler and the head of the rail.

4:. A reinforced concrete rail, a metal covering for said rail extending from end to end thereof, and a metal end piece secured in each end of the metal covering.

5. A rail comprising a hollow head, a pair of web members, said webs supporting the head and formed integral therewith and also forming a base for the rail. reinforcing rods positioned between the webs and extending from end to end of the rail, and a concrete filler for the rail filling the space between the webs and the interior of the hollow head.

6. A reinforced concrete rail, a metallic covering for said rail extending from end to end thereof, a metal end piece secured in each end of the metal covering, and a resilient filler between the head of the rail and the concrete.

7. A rail comprising a hollow steel shell having a non-metallic filler for the shell, and a metallic block fitting each end of the rail and secured therein.

8. A rail comprising a hollow steel shell having a reinforced concrete filler for the shell, and metallic blocks fitting the interior of the steel shell, one block being secured at each end of the rail.

9. A rail comprising a steel shell consisting of a head member and a pair of outwardly flaring web members, a metallic block secured in each end of the rail and fitting the interior thereof reinforcing rods within the steel shell extending substantially from end to end thereof, and a concrete filler for the rail.

10. A rail comprising a steel shell consisting of a head member and a pair of outwardly flaring web members,'a metallic block secured in each end of the rail and fitting the interior thereof, reinforcing rods within the steel shell extending substantially from end to end thereof, a concrete filler for the rail, and a plurality of bracket members secured on each side of the rail, said bracket members being secured by bolts passing through the brackets and the side webs of the rail.

11. A rail comprising a steel shell consisting of a head member and a pair of outwardly flaring web members, a metallic block secured in each end of the rail and fitting the interior thereof, reinforcing rods within the steel shell extending substantially from end to end thereof, a concrete filler for the rail, a plurality of bracket members secured by bolts passing through the brackets and the side webs of the rail, and a shoulder formed on each side of the rail under the head member extending from end to end of the rail, said shoulder engaging the upper ends of the securing brackets.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

W. W. HEALEY, M. E. EWING.
