EDWIN E. SLICK, OF WESTIVIONT, PENNSYLVANIA.

COM'EOUN'D RAIL.

Application filed, November 12, 1913.

T0 all whom 'it may concern.

Be it known that I, EDWIN E. SLIGK, a citizen of the United States, residing in the borough of Westmont, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improve- .ments in Compound Rails; and I do hereby 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 appertains to make and use the same.

My invention relates to railroad rails with special reference to a rail made of two portions, the wearing portion being provided with two heads, so that when one is worn out it may be turned over and the other one used. I also prefer to make the wearing portion of my compound rail of very hard steel which is well adapted to withstand the service to which it is put, while I also prefer to make the base portion of structural or medium steel, which, on account of its toughness and ease of working, is well adapted for its particular portion of the service.

In order that the two parts of my compound rail may be produced by the process of rolling and at the same time be such as to fit tightly together, I provide the web of my base portion with a projection which has an inclination at its lower side and a head portion of greater width which is also inclined. The projection on the web of the base member is adapted to contact with a correspondingly inclined projection on the wearing member, and the inclined top of the head of the base member is adapted to support the correspondingly inclined portion of the `head of the wearing member. The two parts being incontact as described, they are secured firmly together by large bolts or rivets which pass through the web portions of. each member at frequent inter- On account of the inclined surfaces just described, the action ofthe bolts 4or rivets drawing the two parts together. has a wedging and tightening eiect, so that the head portion of the "wearing member is pressed `very firmly against theV correspondingly inclined head vportion offthe base memberand-as clearances are provided .between the webs of the two members,'the two portions can be drawn together more tightly from time to time, if required. I also prefer to stagger the joints in the ,two portions of my compound rail in Vorder that the ac- Speeicaton of Letters Patent.

tion and strength of the same may be substantially continuous in eect and where the base members are joined, I prefer to provide an angle splice bar fitting on the outer side of the track.

Having thus given a general description of my invention, I will now, in order to make the matter more clear, refer t0 the accompanying sheet of drawings which forms part of this specification and in which like characters indicate like parts:

Figure l is a side elevation of my compound rail, this view being taken on the outside of the track and showing the ties and ballast on which the rails are supported. Fig. 2 is a cross sectional elevation on an enlarged scale taken on the line II-II of Fig. l, looking in the direction of the arrows.

Referring now to the numbers of reference on the drawings :-1 represents the base portion in general, 2-2 the base flange thereof, 3 the web, l the head, 5 the inclined upper surface of the head, and 6 a projection or locking strip on the web provided with an inclined lower face as shown. The locking strip 6 may have its lower surface substantially at right angles to the web 3 but I prefer to make it inclined as shown, as it thus coperates with the upper inclined surface 5 of the head t to maintain the wearing portion in proper relative position.

7 is a projection on the upper portion of the base member. vSlight clearances 8 and 9 are originally provided between the projecting portions of the base member and the adjacent portions of the wearing member. The heads of the wearing member are indicated as 10 and are provided with inclined surfaces 11---11A as shown, and the lower sides of the head l0 are also provided with inclined surfaces 12, either of which is adapted to t closely to the upper inclined Vsurface 5 of the base member. V y

At and near the junctions of the two base members I'provide an angle splice bar which is generally represented as 13 provided with a base member 15 adapted to fit the lower flange of saidbase member, a web 14 and a head portion 16 adapted to fit under 4the head portion of said base member. The two portions of my compound rail are held firmly together by means of the bolts 17 provided with the nuts 18, Vor these may be otherwise secured by rivets or similar means. lVIy outside splice bar 13 is secured to the rails by means of the bolts 19 and nuts 20 as shown. The space between the abutting ends of my base members is indicated as 21 and the space between the abiitting ends of my wearing member is indicated as 22.

In practice the rails are assembled. together in positions shown and when, after reasonable use, the upper head 10 isy Worn tothe allowed limit, the boltsor rivets securing ythe portions together are withdrawn, the wearing memberis turned upsidedown and the other head l() thereof, which is not worn, is placed in the upper position ready for USQ- u Iprefer to design my compound rail 1n such a manner that the base member issubrstaitially as strong as the present standard *ails and the `wearing member ltherefore adds strength to the combination, besides which the `wear of said wearing'member does not reduce they strength of the compound rail as low 'as that of the present standard rails. I s

It should also be noted that my wearing memberfis of'substantial depth with a com parati'vely 'thin web and large heads, thus providing a section with a large moment of inertia, 'thus/adapting itto withstand heavy stresses, j

Itushould [be particularly noted that the projection ll ,on the wearing member is adapted 4to `contact with a corresponding projection on the web 'ofthebasemember and at the same time the inclined surface ll2 of the :head port-ion of the wearing member is adapted to cont-act with the upper and similarly inclined surface of the head portion l ofthe base 'inembe The parts being in this position, the Atightening of the bolt 17 tends to draw the two parts of the rail together with great firmness and asno rolled sections can be made mathematically perfectth is method of construction insures a tight lit of the parts at all times so that they `will act in, perfect unison. y 4 Although I have shown and described my improvements in considerable detail, I do not wish to be limited .to the'exact and speciiic details shown and described, but may use such substitutes, 'modifications or equivalents thereof, `as are embraced `within the scope of my invention, or as pointed out in the claims. y
