RAILROAD RAIL.

CARL M. OLSON AND FRANK O. HELLSTRQ 1H, 03 G-BOVE, NORTH DAKOTA, ASSIGNORS TO FRANK O. HELLSTEDM, OF GROVE, "NORTH DAKOTA.

RAILROAD-RAIL.

To all whom, it may concern Be it known that we, CARL M. OLsoN and 1 1mm: 0. l-lnLLs'rnoM, citizens of the United tdtates, residing at Grove, in the county of Burleigh, State of North Dakota, have invented a new and useful Railroad-Rail, of which the following is a specification.

This invention relates to the improvement of railroad rails.

.he invention has for its object to provide for the longevity of the use of rails, the same being reversible, and also provides a factor of safety in that the .rail is constructed of two separate component parts of metal permitting the combination and use of metal of different degrees of temper and hardness, the same being joined together by means of bolts or rivets, being so constructed as to form a continuous rail and wit-h that general I end in view.

A further object is to so-construct or devise the individual parts of the rail structure as to obtain certain advantages which shall be conducive to the aforesaid general end.

A. still further object is to carry out these ends in a simple, effective and expeditious manner.

The invention consists of certain instrumentalities and features substantially as hereinafter fully disclosed and defined by the appended claim.

In the accompanying drawing is illustrated the preferred embodiment of the invention.

It will be understood that various changes and modifications can be made as to the detailed. construction and arrangement of the parts, within the scope of what is claimed without departing from the spirit of the invention.

Figure 1 is a sectional perspective view of the invention. Fig. 2 is an end elevation of the same. Figs. 3 and 4 are separate views in elevation of the primary members of the rail structure.

In carrying out the invention, there is formed a rail-member proper 1 of approxi mately Z-format-ion, the web-forming member 2 thereof, however, being perpendicular to the duplicate tread forming members 3 and 4, which latter are adapted to be reversed or inverted for use either as the tread, or as the base when wear and tear make Specification of Letters Patent.

Application filed July 1, 1912. Serial No. 707,049.

Patented Apr. 1, 1913.

this reversal necessary. Thus, the life of the rail is lengthened.

The duplicate treads 3 and 1 are formed each with a flat surface adapted to constitute a base as well as the tread. The tread-portions 3 and l extend in the opposite directions beyond the web 2 to afford additional stability and also to provide for the ready engagement therewith of the securing spikes. The duplicate tread members 3 and 4 also have their inner edge-portions formed in ogee configuration, as seen at 5, the purpose of which will presently appear. The ogee curve 5 defines a rib 6, whereby the tread is thickened and reinforced and, further, the web-portion 7 of the cooperating angle mem here 8 may be shortened, by reason of which construction certain other advantages follow, as will later be described.

An angle member 8, which is employed for aiding in retaining the rail-member 1, is formed with a knee 9 which rests upon a lateral flange 9 of the tread member a, or upon acorresponding part 9 of the tread member 3, when the rail 1 is inverted. The upper edge of the angle member 8 engages with the upper tread-member in the resultant seat of the ogee-curve 5, whereby the vertical arm 7 of the angle-member 8 is thus centralized. with respect to the railtread, to aid in reinforcing that member, where the greatest stress occurs. The angle member 8 has, it will be noted, a laterally extended lower flange 10 constituting a sup-= porting base, whereby said angle member may be utilized to compensate for less or reduced thickness of web of the steel rail, as well as to allow of lowering or rendering lighter such steel-rail member, as is thought apparent.

The an le member 8 is connected to the web 2 of the rail-member 1 by bolts 11 passing through openings 12 in the member 8 and through elongated openings 14: in the web 2.

What is claimed is A railwayrail of approximately Z-shaped outline, having duplicate tread-members said tread-members having their inner-edge portions of ogee-like formation, an angle member having its upper end received within a resultant seat of the ogee-like formation, said angle-member having a knee adapted to fit upon the base of said railmember, and means for securing said angleas our own, We have hereto affixed our sigmember to sald rall, 111 such a manner as natures 1n the presence of two Witnesses.

to lit and interlock with the inner flange of said reversible approximately Z-shaped rail, gfigg bo g ggs w 5 and said angle-member and Z-shaped rail being united together and supported c0n- Witnesses:
