To 1!-// who/1t it may concern:

be it known that l, Parse P. S'IURDEVANT, a citizen of the United States, residing at Passaic, vented a certain new and useful Improvement in 'lank-Cars. of which the following isa t'ull,

lassaic county, New Jersey, have inter sill-channels, the oppositely-disposed clear, and exact description, such as will en- T i said channels, and the parallel upwardly-expertains to make and use the same. reference able others skilled in the art to which it apbeing had to the accompanying drawings, t'orming part of this specification, in which Figure 1 is a top plan view of one end of a tank-car constructed in accordance with my invention, part of the tank-sills being removed. Fig. 2 is a side elevational view of one end of a tank-car constructed in accordance with my invention. Fig. is a cross-sectional view through a portion of one end of the car, which section is taken through the casting forming the support for the wooden head-block. Fig. i is a sectional view on the line at of Fig. 1. Fig. 5 is a vertical longitudinal view through the car. Fig. 6 is a side elevational view, partly in section, of one of the cross-bearers. Fig. T an elevational view of the bolster, partly in section. Fig. 8 is a perspective view of one of the side plates of the crosshearer: and Fig. 9 is a fragmentary view of the tank, together with the running-board and its supi ort.

This invention relates to a new and useful improvement in undert'raming for cars, but particularly to a metallic undert'rame t'or tankcars.

The object of the invention is to provide a strongydurable, and etiicient undert'ranie capable ot' etliciently withstanding strains to which the undert'rame will be subjected, owing to the vibration of the car over the road-bed, as well as the weight of the tank which it supports.

As illustrated, the invention consists in a 1 center sill comprising two channels 1, extending from one end of the car to the other. These channel members have their tlanges turned outwardly and are provided with a top cover-plate 2. The end sills ot' the car are also shown as channels it, which are connected flanges 10 resting upon the upper tlanges 0t tending flanges l l are connected to the flanged ends of the end ctwer-plates 13, which coverplates are also riveted to the (mtwardly-disposed flanges ot the end sills and the side sills. 6O

, (lasting 8 forms an abutment against which rests the transversely-arranged head-block it, which head-block is secured to the center sills by means of bolts 15, which pass through the same and through the tlanges of said center 5 i sills.

The bolsters ot' the car consist of cast or pressed steel side plates and riveted to the center sills, the ends adjacent to the side sills being secured by the plates 17. The plates 7 16 are connected by the channels 18, which "1 extend from side sill to side sill and rest upon I the top of the cover-plate ot' the center sill.

The bottom cover-plate 19 extends from side sill to side sill, but it is not connected thereto, said bottom cover-plate being riveted to the llanges ot the side plates. The center bearing 20 for the bolster is'tastened by suitable rivets, which pass through said center bearing, the bottom cover-plate for the bol- 3O ster, and the lower flanges ot' the center sills. The side plates 16 extend beyond the compression members 18, being higher than the side and center sills, the top edges being curved on a suitable arc to receive the tank- 5 sills 2i. Brackets 22, which are fastened to the respective side plates, are adapted to receive the ends 233 of the tank-bands. so that the tank will be securely held upon its seat. In order to add strength and rigidity to the 9 bolster, and particularly that part extending A.

above the side and center sills of the car and serving as a tank-support, provide the flanged tie-plates 2%, which connect said plates and are vertically disposed.

The entire end of the-ca is braced by the tie rods 25, which pass through the headblocl; and through the side plates of the bolster. The

diagonal braces

26 and 27 contribute to the bracing effect and diverge from the end toward the sides, said braces being in the form of channels and being connected to the center sill by the

plates

28 or 28 and at their opposite ends to the bolster by the

plates

29 or 29, but not to the side sills.

As heretofore pointed out, the center sillchannels have their flanges oppositely and outwardl y disposed, and these center sill-channels are braced at their lower flanges by inwardlyextending flanges of the angles 30.

The cross-bearers which are arranged intermediate the bolsters consist of top and bottom

members comprising channels

31 and 32. The top or tension members 31 are bent so as to lie flat upon the cover-plate of the center sill, the opposite ends extending above the side sills to points practically in line with the tops of the side plates of the bolsters, and these compression members 31 have their webs connected for a portion of their lengths to the webs of the tension members 32, which tension members are bent so as to extend down beneath the center sills to which they are connected, it being understood that the tension members and the compression members of the side bearers are continuous, the flanges being connected by the side plates 33, which are riveted to the channel-flanges and to the webs of the center sills.

34c designates a running board support, which is secured to the tank of the car and is provided with a continuous upstanding post 35, which supports the hand-rail 36 along said tank.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-
