To tZ-Z whom it may concern.-

Be it known that I, ETHAN I. Donns, a citizen of the United States, residing at Pullman, in the county of Coohand State of Illinois,

have invented certain new and useful Improvements in Underframes for Cars, of which the following is a specification.

The bolsters and side sills of metallic railway-cars are the'subjects of improvement by to my present invention, which includes, instead of the usual tension-plate secured to the bolster, one or more tension or tie rods assing through perforations in the center sills and attached to the ends of the bolsters and to the side sills, partially supporting these parts. In conjunction with the center sills a spacer is employed, the tie-rods extending through holes in said spacer, which forms an additional rest or strut over which the rods pass and upon which theyre st. Each side sill comprises two longitudinal rolled members, disposed one above the'other, and for the under one I preferably employ a Z- beam and for the upper one I use an anglebar. Such a construction secures the benelits of a sin le deep sill and acts in conjunction with t 1e side stakes as a plate-girder without any plates.

In the'accompanying drawingsI have illus- 3o/tlated my invention in a preferred form, like reference characters referring to the same parts throughout.

Figure 1 is a vertical cross-section adjacent to the body-bolster of a car'embodying my invention. Fig. 2 is a section of a portion of the car shown in Fig. 1 on the lino 2 2, as viewed in the direction indicated by the ar rows. Fig. 3 is a plan of a fragment of the underframe of the car and shows in detail the 4,0. manner of securing the outer end of the bodybolster to the side sill. Fig. 4 is a cross-sets tion of the body-bolster shown in Fig. 1 on the line 4 4, and Fig. 5 is a perspective view of: the anchor or tie-plate, one of which is secured to each outer end of the body-bolster and. attached to the side sill, the tie rod or rods being fastened to the anchor.

The channel center sills 1O 10 are spaced apart and tied together by member 11,which has a central web 11 with integral outstanding flanges 11 on all four edges, the flanges projecting from both sides of the web, as is shown in Fig. 2. An additional channel- 'spacer 12 with its flanges projecting u wardly is fastened above spacer 11 to tie webs of the center sills, the center sills and the flanges of this latter spacer having perforations in aliuement for the passage of the tie-rods, as shown in Fig. 1. The bodybolster beams comprise spaced pressed-steel beams 13 with integral flanges along their upper and lower edges placed with their webs back to back, as illustrated in Fig. 4, each half of the bolster having short tie-plates 14, riveted to the upper flanges of the channelbeams 13. Angle-bars 15 secure the inner ends of the bolster-beams to the center sills, rivets passing through the center sills, the angle-bars, and the flanges 11 or spacer 11. At their outer ends the bolste rbeams have integral flanges 16, which are turned over from the webs of the pressed-steel beams and which are riveted to 2-beam side sills 17 and to the flanges of side stakes 18. A compression-plate 19 is also fastened to the owcr flanges of bolstenbeams 13, passing under the center sills. At the outer ends of the body-bolster I su ply anchors 20, each of which. has a vertical portion or flange 21, adapted to fit between and be riveted to the bolster-beams 13, a lower inclined portion or flange 22, intended to lie against and be riveted to the lower flanges of beams '13, a hori-- zontal portion or flan e 23 to bear against and be fastened to the ower flange of the Z- beam side sill, and one or more perforated bosses 24.

Instead of the usual tension-plate riveted to the bolster and extending across the center sills I employ one or more tension or tie rods 25, (in the present instance two,) which pass through the perforations of the center sills and channel-spacer 12 with their outer ends fitted in the bosses of the anchor 20, nuts 26 being screwed on their protrudin ends to properly hold them in place. It will be observed that these tension or tie rods partially support the outer ends of the bolster-beams and the side sills and are espe-' cially ell'ective for this purpose because of their long span or reach.

Above the Z-beam side sills 17 I employ longitudinal angle-bars 27 with their horizontal flanges extending inwardly, these angles also being riveted to the flanges of the side stakes 18. By this construction I se cure, in effect, dee side s'ills,which answer all the purposes of plates. lVooden stringers 28 rest upon and cured to theupper side of the body;bo sters, floor-planks 29 being nailed or otherwise fastened thereto. The upright side and end planks 30 are preferably bolted to the side stakes, as shown in' Fig. 1, and ends of the car-body. I

Minor changes in the details of construction will suggest themselves to those skilled in. the art, and hence the invention is not limited to the details as shown and described, except to the extent to which they are made the subject-matter of specific claims.

This patent is intended to embrace only so much of the disclosure made herein as is covered by the claims.
