BODY-BOLSTER.

ooneea.

To all whom it may concern:

Be it known that we, ROBERT E. FRAME and JOHN M. ROHLFING, residing at St. Louis, Missouri, and being citizens of the United States, have invented certain new and useful Improvements in Body-Bolsters, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the eXact details of construction shown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art.

In said drawings: Figure 1 is a plan view of improved bolster. Fig. 2 is an elevational View thereof. Fig. 3 is a transverse sectional view, the section being taken central of the center bearing on line 3-3 of Fig. 1. Fig. 4 is an end elevational view. Fig. 5 is a vertical sectional view, the section being taken on line 5-5 of Fig. 2. Fig. 6 is a diagrammatic elevational view showing the girder from which the bolster is constructed in full and dotted lines indicating its original shape and the lines along which it is cut through its web portion.

The object of the invention is to provide a simple, strong and durable body bolster formed of a single l-l section of rolled metal, which is of less depth near its end portions than near the middle and is reinforced in such a manner as to best serve the purposes for which it is intended.

Referring to the parts, 1 is the upper flange which is continuous from end to end and is connected throughout its length with the web 2. 3 indicates the part of the lower flanges which is left integral with said web 2.

4-4 indicate the end portions of the lower flanges which are severed from the web 2 and from the portions 5 of said web which are cut out and removed from the girder.

6 indicates a Vertical opening extending from top to bottom through the girder, as shown in dottedlines in Fig. 6.

After the portions 5 of the web are out out, leaving the two flanges 4 at each end severed from said portions 5, the said flanges 4 are bentupwardly to the position shown 5 in Fig. 2 and as indicated in section in Fig.

- Specification of Letters Patent.

Application filed June 15, 1909.

Patented Aug. 29, 1911.

Serial No. 502,367.

5. The bottom flange 4, may be bifurcated longitudinally in alinement with the web 2, so that when the flanges 4, are bent upwardly as shown in Fig. 2, they will rest at each side of the web as in Fig. 5, if desired, although the portion 5, may be cut out without bifurcating the bottom flange 4. The pin socket members 7, which may be either pressings or castings, are placed in position and riveted to the top flanges 1 and to the web portions 2, as best shown in Fig. 2. Said pin socket members are preferably castings which are provided with reinforcing ribs 8 extending downwardly approximately the depth of said member 7 and said socket members 7 rest upon the upper edges of longitudinally disposed angles 9, which extend at each side of the web 2 substantially the length of the bolster and are riveted to said web and to the lower flanges 3-4 throughout their length, some of the rivets connecting these angles 9 with said lower flanges 3 extending through the laterally projecting flanges 10 of the center bearing 11, thereby securing said center bearing in position, as best shown in Fig. 2.

For convenience of manipulation the ver tical legs 9 of the angles 9 are cut away slightly at their ends to provide suflicient clearance between said angles and the horizontally extending flanges 1 of the bolster. Side bearings 12 are provided for well understood purposes.

.What we claim is:

1. In a bolster a rolled member provided with integral top flange and bifurcated lower flange.

2. A bolster comprising a rolled member provided with a continuous top flange and a bifurcated bottom flange.

3. In a bolster, the combination comprising a rolled member having integral upper flanges and web portion, a bottom flange bifurcated at its end portions and continuous angles connected with said bottom flange and the web portion.

4. In a bolster, the combination comprising a flanged girder member of rolled metal, parts of the flanges of which are cut from its 1web and subsequently connected therewit 1.

5. In a bolster, the combination comprising a flanged girder member of rolled metal with bifurcated flange and means connecting said bifurcated portion with the web.

6. In a bolster, the combination comprising a flanged girder member of rolled metal having one of its flanges bifurcated from the ends inwardly, in combination w th reinforcing means connecting said bifurcated flange to the web.

7. In a bolster, the combination comprising a flanged girder member of rolled metal having one of its flanges bifurcated from the ends inwardly, in combination with a reinforcing member extending longitudinally of and connected with said bifurcated flange,

8. In a bolster, the combination comprising a flanged girder member of rolled metal having one of its flanges bifurcated from the ends inwardly, in combination with angles connected with the web and said bifurcated flange.

9. In a bolster, the combination comprising a flanged girder member of rolled metal having one of its flanges bifurcated from the ends inwardly, in combination with longitudinally extending angles above said bifurcated flange forming a pin seat.

10. In a bolster, the combination comprising a flanged girder member of rolled metal having one of its flanges bifurcated from the ends inwardly, in combination with longitudinally disposed strengthening means connecting said bifurcated flange with the web, and a center bearing secured to a flange of said girder and to said angles.

11. In a bolster, the combination with a rolled and flanged girder member, parts of whose lower flanges are cut from the web thereof, of means for attaching said flanges to the web and a center bearing connected with the uncut portion of said flanges.

12. In a bolster, the combination with a rolled and flanged girder member having integral upper flanges, a depending web and integral lower flanges near its middle portion, of flanges severed from said web and rejoined near its end portions.

13. In a bolster, the combination with a rolled and flanged girder member having integral upper flanges, a depending web and integral lower flanges near its middle portion, of flanges severed from said web and rejoined near its end portions and a center bearing member connected with the integral lower flanges.

14. In a bolster, the combination with a rolled and flanged girder member having integral upper flanges, a depending web and integral lower flanges near its middle portion, of rejoined flanges near its end portions and vertically disposed central stiifening means.
