To all whom it may concern Be it known that I, JACOB H. Wnrsenoo, residing at St. Louis, Missouri, and being a citizen of the United States, have invented certain new and useful Improvements in Cast-Steel BodyBolsters; of which the fol lowing 1s 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 accom panying drawings, which illustrate the preview. Eig. etis an end elevational view of the cast" metal parts of the bolster comprising the presentinvention. Fig. 5 is a section'al" view, the section being taken On line.

5''5 of Fig. 2, looking inthe direction indicatedby the arrow. Fig. 6 is a similar view, the section being taken on line 6-6 of Fig. 2, looking inthe direction indicated by the arrow.

Referring to the parts, it will be noted that the major portion of the bolster, forming the subject-matter of the application, is of cast metal, comprising a central filled portion 7 and wings 8-8, with a continuous bottom flange 9 extending from end to end of the bolster and with sill pockets 10 interosed between the wings 8 and the central filler portion 7. Extending longitudinally of the car underframe, when the bolster is in position, and transversely of the bolster are vertical flanges 12, to which are attached the lower portions'of the Webs 13 of center sills, which center sills will be hereinafter more specifically described. Opposite the flanges 12 and comprising a, part of the flange outlining the wings 8, are other vertical flanges 14;, which, with the bottom flange 9, outline. said sill pockets, which pockets are open at the top for the insertion therein of center sills of a car underframe. Spanning the sill pockets 10 and lapping the bolster Wings 8 is a top cover plate 15, which is secured by vertical rivets 16 to l i Specification of Letters Patent; Application filed December 9, 1913. Serial'No. 805,558.

flanges 17 of said wings," said top cover plate 15 having a thickened portion 18, :which provides shoulder-s19 adapted to con- ;tact with the upper inner faces of said vertical walls 14, so that when a car in which the bolster is employed is lifted by means of fjacks placed. under the outer ends of said bolsters and the upper portion of the bolster :is in compression, said shoulders 19 will be incontact with said upper inner faces of the vertical walls 14, thereby relieving the rivets 16- of stresses ordinarily incident to such operation. To compensate for the increased weight due to the thickened portion 18 of v :the cover plate, channels-20 are formed in the upper face thereof, said channels preferably extending at each side past the central filler. a

In assembling the parts shown, the sills having been first provided with slots therefor, the top cover plate 15 is projected; through said slots 21 of the-sills, said slots being preferably only suiliciently large to permit ready insertion of said top cover late, after which the remaining portion of t e bolster, including the Wings 8 and central filler, is lifted to position in contact with the underside of said top cover plate, and connected thereto and to said center sills. onnected with the webs 13 of the center'- sills are top and bot-v tom rolled

sections

25 and 26, formin compression and tension chords for sai sills,

the center sills intermediate theflanges 25' the parts are assembled as hown in Fig.1,

increase the sectional area of the sills. at the bolster and occupy a position below the middle portion of said cover plate 15. The shoulders 19 of said cover plate depend be- .low the normal plane of the top middleportion of the body. of the bolster into the pockets 10, and the cover plate 15 will be supported by the wings 8 and central filler of the bolster. The bolster filler portion 7 is of less height than the body portion of the bolster wings. or extensions adjacent said pockets 10, hence the thickened or inset depending portion ofthe plate 15 with its shoulders 19 rest in horizontal alinement with the inner or middle portions of the top bolster flanges 17, that is in alinement with the body portions of the wings, thereby pro- Bum vertical inner faces of some of said walls.

2 In a cast bolster, a unitary casting.

comprising a center filler portion, extensions or wings projecting outwardly at each side of and to a greater altitude than said portion, said bolster having sill pockets at two sides of said filler portion, a top cover plate riveted to said extensions and depending shoulders formed on said cover plate adapted to contact with inner faces of some of the walls of said pockets.

3. In a bolster, a center filler portion having vertical walls, center sills riveted directly to said walls and extending to a plane higher than said walls, said bolster having wings extending transversely of said sills and to a plane higher than said centerfiller and having sill pockets intermediate said wings and center filler portion, and a top cover plate projected through the webs of said center sills and connected with said wings, said plate depending below the top plane of said wings and abutting spaced walls of said pockets.

i. In a body bolster, a unitary casting comprising a center filler portion having vertical walls. and spaced wings. extending to aplane higher than the top of said filler with sill pockets intermediate said filler portion and said wings, built up'center sills comprising vertical web plates and having flanges resting in said pockets and a bolster top cover plate passed through openingsin the webs of said center sills, a m ddle portion of said cover plate extending in alinement with body portions of said wings, and said cover plate being secured directly to said wings.

5. In a body bolster, a unitary cast ng comprising a center filler portion having vertical walls and spaced wings with sill pockets intermediate said filler portion and said wings, the wings extending to plane higher than the filler portion, built up center sills comprising vertical web plates with bottom flanges resting in said pockets and a bolster top cover plate passed through openings in the webs of said center sills, said top cover plate lapping and. being secured to said wings and having a. depending middle portion forming shoulders thereon adapted to contact with upper inner faces of said wings in the normal plane of said wings.

6. In a body bolster, a unitary casting comprising a center filler portion having vertical walls and spaced. wings extending to a higher plane than said filler portion, there being sill pockets intermediate said filler portion and said wings, center sills comprising vertical web plates and flanges resting in said pockets and a bolster top cover plate passed through openings in the webs of said center *sills, said top cover plate having end portions lapping and be ing secured to said wings and having an intermediate portion depending to a plane below the body portion of said plate, thereby forming shoulders to contact with some of the walls ofsaid pockets.

In witness whereof I have hereunto set my hand in the presence of two witnesses. JACOB H. WEISBROD. Witnesses:
