ELEMENT USED IN GAR CONSTRUCTION.

Specification of Letters Patent.

Patented July i912..

Application filed September 19, 1910.` Serial No, 582,634.

To all whom @'15 may concern:

Be it known that l, RALPH G. TAYLOR, a citizen of the United States, residing at Davenport, in the county of Scott and State of lowa, have invented new and useful lmprovements in Elements Used in Car Construction, of which the following is a full, clear, and exact description.

My invention relates to elements used in car-construction, and particularly to the kind now extensively used in metal underframes for center-sills, bolsters, and crossbeams.l

The object of my invention is to provide a truss-shaped or lish-bellied shape car element by reducing the ends of the vertical web of an l-beam, which can be manufactured at a low cost, will consist of but few pieces, will also be light, and of sufficient rigidity to withstand the strains to which it is subjected. rlhis l accomplish by the neans and in the manner hereinafter fully described, and as more particularly pointed out in the claims, reference being had to the accompanying` drawings forming a part of this specification, in which,

Figure l is a side elevation of my invention. Fig. 2 is a similar view on a larger scale of one end of the same. F ig. 3 is a transverse section near one end of the same. Fig. a is a transverse section taken on line 3 3, of Fig. 2. Fig. 5 is a transverse section of a modified form of my invention. Figs. 6 and 7 show, respectively, a cross section at about the same point that Fig. 3 is taken, and a crosssection at about the point where Fig. 4 is taken, of yet another modified form of my invention.

ln the drawings, A represents an l-beam, the upper flanges a of which are left intact from end to end, but the lower flanges Z of which are removed at each end and throughout the central port-ion of the beam is left intact. rlhe ends of the beam are reduced by cutting away the under edges of the same commencing at a point some ve or six feet, say, from the ends. rl`his cut away portion leaves rather abrupt shoulders c at the ends of the lower' 'flange at the points where said cutaway portions commence, and from thence the lower edge of the web of the beam inclines upward for a suitable distance and then continues substantially parallel to the upper flanges to the ends of the beam. The lower edges of these cut-away end portions of the beam are reinforced by strips C of an angleiron, or other suitable material, which are riveted thereto so that the under surfaces of their horizontal flanges will be flush with the lower edges of the web of said beam. rl'he lower end portions of these strips, how ever, are continued beyond shoulders c and are bent so as to extend horizontally above and parallel with the end portions of the lower flange Z), and these extensions are secured by rivets c to the web of the beam A, and by rivets f to the lower flange o of the said beam, and l prefer to interpose fillers E between the said lower flanges 0 and the parallel flange of the angle strips C. 'These fillers consist of tubular spools or sleeves having their lower ends disposed at a slight angle to their axes to enable them to bear flat against the upper inclined surface of the flanges o and thus secure a thorough and perfect assemblage of thereontiguous elements of this part of my invention. A set of bearing-plates G having flanges eX- tending in the direction of the length of the beam are secured by means of rivets g to lower horizontal flanges of the strips C near the ends of the beam, substantially as shown in Figs. l and 2 of the drawings, and in order to permit of the passage therethrough ofra suitable continuous l-beam bolster l-l, an T.-shaped opening is made in the web of said beam in the transverse plane of the center of the bearing-plate Gr. lf desired, a continuous needle-beam may be substituted for the bolster and may be passed transversely through a similar opening in the web of said beam A, but in either event, l prefer to reinforce the web surrounding said opening by a cast metal reinforcing plate, l, substantially rectangular in shape, and to rivet the same to the web of said I- beam. The lower port-ions of these plates are off-set slightly outward so as to lap over and permit the vertical flanges of the reinforcing strips C to pass under them, and the edges of the openings in these plates, l, through which the holsters pass, are provided with transversely projecting flanges that constitute a cored l-shaped bracket J that assists in the support of the bolsters and permit the same by means of rivets through their vert-ical portions to be sepured indirectly to the beam A and greatly strengthen the car construction at the intersection of the said beam and bolsters. It will be understood that this method of securing the beam A and bolster may, if desired, be dispensed with, and when continuous needle-beams (not shown) are employed at other points along the length of t-he beam, a similar construction of the parts including a reinforcement plate and bracket may be adopted. It will also be understood that the beam with the ends cut away and reinforced may be used in the construction vof other parts of the underframe of a car without the presence of either the bolsters or needle-beams or their bearing elements.

I prefer to construct my improvements as hereinbefore described when said angle-iron reinforcing-strips C, C, are made of rolled metal, but when they are made of pressed metal I prefer to secure the horizontal flanges of said strips directly to the lower flanges 3, 3, of the central portion of the I- beam 4l, as shown in Fig. 5 of the drawings. In this latter event, shoulders c, c, of the beam A could be dispensed With, or, if they were retained, thefinclined port-ions of the strips could be disposedat a slightly greater angle so as to bring the under surfaces of the horizontal fianges of the lower ends of said strips in contact with the upper surfaces of lower flanges 3 of the beam, and thus dispense with filler-spools E. If it is desired to still further strengthen the reinforcing-member of my improved car element I can, as shown in Figs. 6 and 7 of the drawings, reinforce the lower edges of the beam by a channel-iron supplemental reinforcing-member X. In such case I prefer to use the modified form of my improvement shown in Fig. 6 of the drawing so that the channeled upper surface of said channeliron supplemental strip will bear against the under surfaces of the end portion of the lower fianges 3 of the beam and the under surfaces of the angle-iron reinforcing-strips 2, 2, thereof.

1vVhat I claim as new is l. A car element comprising a suitable I- beam the lower edges of whose end portions are cut-away in opposite directions, and angle-iron strips the inner end port-ions of which are arranged above and parallel to the end portions of the flanged central portion of the beam, a series of filler-spools placed between the lower flanges of the beam and the horizontal flanges of the angle-iron strips, and rivets extended therethrough and securing the said flanges together.

2. A car element comprising a suitable I- beam the lower edges of whose end portions are cut-away in opposite directions, angleiron strips the inner end portions of which are arranged above and parallel to the lower flanges of the central portion of the beam, a series of Eller-spools placed between the lower flanges of the beam and the horizontal flanges of the angle-iron strips and securing said flanges together, and means for securing the vertical flange of the angle-iron to the web of the beam.

3. A car element comprising a flanged metal beam the lower edges of whose end portions are cut-away at an angle, and angular metal members for reinforcing the edges of said cut-away end portions, which members are secured to the web of the beam and are spaced away from but secured to the ends of the remaining portion of the lower flange of said beam.

In wit-ness whereof I have hereunto set my hand this 14th day of September 1910.
