STRUCTURAL Application filed June 3,

This invention relates; to a steel construction and particularly to a structural steel beam capable of use for structural work for metal ties and other purposes.

The OlJjCCJ of the invention is to provide an improved structural beam wherein a strong, rigid structure is provided capable of acting eiliciently in structural work with certain parts so formed as to be bent to act as shoulders when the beam is being used for a metal tie.

A further obj ct, more specifically, is to provide a structural beam which may be used in any length for structural purposes or may be cut into short lengths and used as an open ended metal tie or used as a closed end metal tic after having the ends stamped or pressed in such a manner as to closethe ends without all ecting the remaining part of the structure. I

In. the accompanying drawings Figure 1 is a perspective view showing a short section of a beam disclosing an embodiment oi the invention.

Figure 2 is a perspective view of a metal tie termed from a beam similar to that shown in Figure l, the same being pressed, at the ends so as to present a closed tie body.

Figure 3 is a fragmentary perspective view showing the beam formed into a tie body similar to Figure 2, except that the ends are shown open.

Figure t is a view similar to Figure 3 but showing a different form of clip rec iving notch.

Figure 5 is a plan view showing the beam with certain of its flanges partly bent over as the same is being formed into a tie structure.

Figure 6 is a sectional view through the beam as it is being rolled into shape, the central part being shown completely formed.

Figure 7 is a view similar to Figure 6 but showing the beam in a further completed form.

Figure 8 is a fragmentary view showing how certain of the flanges may be bent over in a preliminary manner.

Figure 9 is a view similar to Figure 8 but showing the central flanges completely bent over for presenting overhanging shoulders as illustrated in Figures 2, 3 and 4.

When constructing the beam, the same may be rolled in different waysbut, preferably, is rolled from fiat sheet metal and in METAL BEAM.

the rolling, the desired strip of metal is passed between the

various rollers

1, 2, 3, a

10 11, 12 and 13 whereby the sides of the beam are formed with the feet or bottom flanges. After this has been done, the structure is a finished beam as illustrated in Figure 1 capable of use in structural work of ditlerent kinds.

Where the beam is to be used for a railroad tie, the same is cut off into the desired lengths and it so desired, is left open at the ends as shown in Figures 3 and 4, though preferably, the ends are pressed or bulldosed down as shown in Figure 2 so that the tie body 14 will be closed at the ends which will prevent any longitudinal movement when in use. When the parts are turned down as shown in Figure 9 so that the beam may be used as a railroad tie, the

flanges

8 and 9 form overhanging shoulders overhanging the groove 7 whereby the same may interlock with the head of a bolt used in clamping a rail in position on the tie as illustrated in my Patent 1,550,925, granted August 25, 1925.

As indicated particularly in Figure 2, a pair of notches 15 are arranged adjacent each end of the tie body 14, said notches being adapted to receive the turned down portion of a tie clip illustrated in my patent above mentioned, whereby a bolt with its head in the groove 7 and interlocking with the shoulders or

flanges

8 and 9 will firmly clamp the clip in place which in turn will hold the rail in place. When the ends 16 are stamped or pressed down so as to close the same, the

flanges

8 and 9 will naturally be turned down therewith and, consequently. the head of the bolt could not be inserted very readily into the groove 7 so that comparatively

large notches

17 and 18 are arranged near each end of the tie body whereby the head of the bolt may be inserted downwardly into the groove 7 and then moved longitudinally of the groove with the body of the bolt extending through the slot 19. Where the tie body 14 is open at the ends, the

notches

17 and 18 are not necessary but the notches 15 are usually necessary. If desired, instead of torming a single pair of o an) structure at the center, said body extending I laterally in opposite directions from the vertical center of each leg of the U-shaped structure.

2. A metal beam, comprising a portion- U-shaped in cross section, members extendmg laterally in opposite dlrections from the center of the legs of the U-shaped structure, and side members extending from the edges of the laterally extending members.

'3. A metal tie, comprising a tie body formed With a longitudinally positioned groove, and a pair of flanges overlapping said groove but spaced apart for present ing a slot therebetween, said flanges presenting overhanging shouldergeach of said flanges being formed with a (lip receiving notch and a notch for permitting the head of a bolt to be inserted into said groove.

4. The method of forming a metal tie, comprising rolling a substantially U-shaped structure with depending portion in the upper surface, forcing part of the upper surface over the depending portion for forming overhanging flanges, and closing the ends of the tie by forcing the same.

5. The method of forming aunetal tie, comprising rolling a tie body substantially U-shap'ed in cross section with a depending portion in the upper surface and pair of flanges extending upwardly from said 'up per surface on each side of the depending portion, rolling said flanges until they overhang said depending portion and forming clip receiving notches in said flanges, and finally forcing the ends of the tie body closed.

6. A structural metal beam, comprising a body formed with a substantially U-shaped structure at the center, said body extending laterally in opposite directions from substantially the opposite sides of each leg of said U-shaped structure.

7. A metal tie, comprising a substantially inverted trough-shaped body bent down and closed at each end, said body being formed with agroove extending for the full length thereof in the upper surface, said groove extending to the bottom of said bent down ends, said body being formed \vithintegral flanges overhanging said groove for presenting shoulders for receiving clamping bolts, said flanges being also formed with clip receiving notches having notches for permitting the heads of clamping bolts to be inserted into said groove.

8. The method of forming a metal tie, consisting in rolling a substantially U- sh'aped structure with a depending portion in the upper surface, and then forcing part of the upper surface over the depending portion for forming overhanging flanges.

9. The method of forming a metal tie, consisting in roller a tie body substantially U-shaped in cross section with a depend ing portion in the upper surface, and a pair of flanges extending upwardly from the upper surface on each side of the depend ing portion, rolling said flanges until they overhang said depending portion, and tinally forming clip receiving notches in said flanges.
