. BAIL 0R ROLLED MEMBER.

Application filed February 5, 1926. Serial No. 86,236.

This invention relates to an elongated or logitudinally extending member which is commonly used for beams, such as an angle section, I-beam or railroad rail. Such members are usually made of steel and are. now commonly made as rolled members or sections. The general shape of such members is determined by the use to which they are put and this shape being determined, it is desirable. to dispose the metal in the member and proportion the parts so that the greatest strength is secured.

It is an object of this invention, therefore, to produce such an elongated member having ribs adjacent its sides with resulting compressed spaces between said ribs whereby the metal which would otherwise occupy such spaces may be disposed at other parts of the member.

It is more specifically an object of theinvention to provide such an elongated member having webs or flanges extending substantially at right angles and joined by a curve or fillet, said member being provided with transversely extending and projecting ribs adjacent this fillet.

It is still another object of the invention to provide a railroad rail having transversely extending and projecting spaced ribs at the curve or fillet portions, adjacent the base flange and head of the rail, said rail also preferably having spaced ribs and intervening notches adjacent the outer top edges of the base flange. I

These and other objects and advantages of the invention will be more fully set forth in the following description made in connection with the accompanying drawings, in which like reference characters refer to the same parts throughout the different views and in which:-

Fig. 1 is a vertical section through a railroad rail taken at right angles to the longitudinal center line of the rail and showing in dotted lines the fish or joint' plates clamped to the sides of the rail.

Fig. 2 is a perspective view of a portion of the rail shown in Fig. 1;

Fig. 3 is a vertical section through an I- beam, said section beingtakenat right angles to the longitudinal centerline of the beam, and

Fig. 4 is a view in side elevation of a portion of the beam shown in Fig. 3.

Referring to the drawings, in Figures 1 and 2 a railroad rail 5 of the form n'owcominvention a portion of the metal at these fillets is in one sense removed at spaced intervals so that the rail has at these fillets transversely extending and projecting ribs 5 and 5 as clearly shown in Figs. 1 and 2. As shown in Fig. 2 the ribs 5 preferably are arranged in staggered relation to the The base flange 5 also has a portion of the metal of the flange and web removed, forming spaced slots or grooves 5 at the outer edges of the flange at the top surface thereof. The rail shown in Figs. 1 and 2 can contain the same amount or weight of metal per lineal unit as the rails of the prior art and the metal which is taken from between the ribs 5 and '5 and from the grooves 5 will be disposed in other parts of the rail. While this metal may be variously disposed, as by being put in the web 5 so as to increase the height of the web, in the embodiment of the invention illustrated the extra metal is shown as being placed on top of the rail head as indicated in the closely sectioned portion 5 In Fig. 1 the sections of fish or joint plates 6 are indicated which plates are commonly used to connect the adjacent rail sections, these plates being connected by the headed and nutted bolts 7 having the spring lock washer 8 disposed under the nut 7. It will be seen that the heads 6 of the plates 6 extend under the head 5 of the rail and some distance along the surface of the ribs 5. However, the outer edge of the rail beyond the ribs 5 also contacts with the heads 6*. The bottoms of the plates 6 contact'with the top of the base flange 5 and with the top of the ribs between the grooves From the above description it is seen that applicant has provided a very much improved rail. The strength of the rail in resistance to bending at the top and bottom of the web 5 is not appreciably lessened and the strength of the rail is not substantially impaired by the grooves 5. The metal not used between the ribs 5 and 5 and saved by the grooves 5", however,

increases the total height of the rail and thus increases the moment of inertia. The I head 5 strength of the rail as a beam is thus increased appreciably. The dimensions of the rail head are increased and a stronger head is thus provided and one which will wear considerably longer than the rails of the prior art. The plates 6 are positioned the same distance from the center of the rail as in the previous rails. Ample contact is afforded between .these plates and the rail head. The ribs 5 engage plates 6 for some distance and the rail head between said ribs engages the plate well toward the center of the top of said plate. The resultant line of pressure on the plate is thus moved toward the center of the plate. This line being nearer the transverse center of the plate, the plate can be made subject to fewer and simpler stresses than if it was farther inward. The position of line 5 tangent to the fillet 5" may be varied and the distance between the point of intersection of this line with the top of ribs 5 and the side of rail would be correspondingly varied. It will be seen from Fig. 1 that the space between the ribs 5 extends above or inwardly of the undersurface of the parts 5 of the rail head. Dotted line 5 indicates how line 5* might be in a higher position. The holding and positioning effect of the plates 6 is just as eflicient as the structures of the prior art. The grooves or notches 5 also give inuch better opportunity for the attachment of anti-creeper plates which are commonly usedvon railroad railsand adapted to engage the cross ties. It will be noted that the moment of inertia of the rail will be increased whether the extra metal is placed on top of or in the head 5 or is used to give increased height to the web 5". A much more etficient .rail section is thus produced with the same amount of metal per lineal unit.

In Figs. 3 and 4 an I-beam 10 is shown of substantially standard form except that metal is taken from the portion at the inner side of flanges 10 and at the curved or fillet portions where said flanges join the web 10". This results in transversely extending ribs 10 at the inner sides of flanges 10 and these ribs 10 on the top and bottom flanges are' in staggered relation. The metal which is saved from the spaces between ribs 10 may be used to increase the height of the web 10 or may be added to increase the width of the flanges 10 as indicated at 10 It will be seen that the moment of inertia of the beam will thus be increased, while the resistance to bending of flanges 10? is substantially the same. The increased width of flanges 10 gives greater supporting surface or more bonding surface if the beam is used in concrete. A very much improved section is thus produced. It will thus be seen that applicant has provided an elongated member which may have the same weight per lineal unitas similar members of the prior art, but which is much more efiicient in form. Said member can be easily manufactured with little or no extra expense.

It will of course be understood that various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of applicants invention, which, generally stated, consists in a device capable of carrying out the objects above set forth in the novel parts and combinations of parts disclosed and defined in the appended claims.

\Vhat is claimed is:

1. An elongated metal member havin longitudinally extending portions disposed at right angles, said member having spaced ribs extending transversely of said portions at the junction of said portions, whereby metal may be omitted at said junction and used to increase a dimension of one of said portions.

2. A rolled'elongated metal member having a web, and a flange extending substantially at right angles thereto and joined by fillets, said member having ribs extending transversely of said web and flange at said fillets whereby metal may be omitted between said ribs and added to the dimensions of said web and flange.

3. A railway rail having a head and a base flange connected by a central web and having fillets joining the web to the said head and flange, said rail having transversely extending and projecting spaced ribs within said fillets whereby metal may be omitted from between said ribs and disposed to increase the height of said rail.

4. The structure set forth in claim 3, said rail also having spaced grooves formed therein at the upper'side edges of said base flange.

5. The structure set forth in claim 3, the ribs at the top and bottom of said web being arranged in staggered relation! 6. A railway rail having a head and a base flange connected by a central web and having fillets joining said web to said head,

said head having an undersurface extending inwardly and downwardly towards said web, said rail having depressions therein at the junction of said surface and web extending into and above said under surface, whereby the metal omitted from said depressions may be used to increase a dimension of said rail.

In testimony whereof I affix my signature.
