RATION OF JERSEY.

NQ. sismo.

To @ZZ whom,l t may concern:

Be it known that I, THOMAS R. BROWN, a citizen of the United States, residing in the city, county, and State of New York; have invented a certain new and useful Improvement in Hopper-Bottom Cars, of which the following is a full, clear, and exact description', such as will enable others skilled in the art to vwhich'it appertains to. make and use the same, reference being had to the accompanying drawings, forming' part of this specification, in which* .Figure 1 is a side elevational view of approximately one-half of my improved car. Fig. 2 is a longitudinal vertical sectional view 3 is a plan View of the underframing at the end of the car. Fig. 4 is a vertical cross-sectional view in the transverse-plane'of the bolster.v Fig. 5 is a vertical cross-sectional view inthe transverse plane of the center of the car, and

Fig. 6 is a cross-ridge.

This invention relates to a new and useful improvement in cars, and particularly to that type known as hopper-bottom cars, although it-is obvious that features of the invention could be employed in cars of other types without departing from the nature and principle of the same.

My invention consists in the construction, arrangement, and combination of the several plan View showing the central parts, all as will be hereinafter described, and

afterward pointed out in the claims. l

In the drawings, 1 indicates the side walls of the car, which form plate-girders and sustain l the major partof the load. These walls are provided with top and bottom flanges, forining the compression and tension fianges, re-

spectively, of the plate-girder sides, and, as

shown, these flanges are in the nature of angles riveted to the upper and lower edges of the walls; but it is obvious that the flanges walls. To reinforce the side posts, vertical stiffeningosts 2 are employed, and said posts are pre erably ridged as shown in Fig.v 1 they being arranged on the outer faces of thfeJ side walls with their ridges presented outwardly. As an additional strengthening medium for the side walls, plates 3 are anranged on the inner faces of the side walls, through which the rivets for securing the posts 2 in position pass;-

ST. LOUIS, MISSOURI, CORPO- HOPPER-BOTTOM CAR- Patented March 27, `..906.

4 indicates the center sills, which are preferably in the form of 'channels withl their flanges presented outwardly, said center sills being shown as extending from end to end of the car, although it is obvious that .they could be interrupted and made of two or more pieces, as is well known in this art.

5 indicates the vertical web yof the bolster, (see Fig. 4,)'whic'h is recessed in its lower edge to take in the center sills, which center sills at'this point are spaced apart by a fillercasting or diaphragm 6, -preferably cored to receive lthe `kmg-bolt. The bolster-web 5 extends from side to side of the car and is strengthened by angles 7, riveted to the faces thereof, the said angles being properly disposed to resist buckling tendencies. The upper edge 5*1 of the bolster-web 5 is bent or deflected (see Fig. 2) so as to lie perpendicular to the inclined end floor-sheet 8, said bent edge being secured to said floor-sheet by means of connecting-angles or bent plates 9, preferably arran ed on each. side thereof. The lower edge o the bolster-web 5 is stiffened by angles 10, which also afford a connecting medium for the bottom cover-plate 11 of the bolster, which extends under the center sills and, together with the center late 12, is riveted thereto and to the fillerblock 6. y y

13 indicates short s'id'e. sills, preferably made in the form of channels with their flanges presented inwardly,- the top flange 13 thereof being cut away 1n the transverse plane of the bolster, as shown F 2 ,so as to accommodate the connecting-angles 14, which secure the bolster-web to the webs of the side sills and the posts in thel transverse plane of the bolster.

15 indicates the outside hopper-sheet,

whose upper edge is riveted to the side wall of the car, and 16 indicates the inside hoppersheet, Whose upper edge is bent inwardly over the center sills and riveted to straps 17, arranged between the center sills. 'lhe upper edges of the inside hopper-sheets above the straps are flanged and riveted together. Both hopper-sheets at their lower edges are preferably flanged, so as to provide means for the attachment of the inclined end floorsheets. r

18 indicates a vertical web `extending across the center of the car and above the cen- ICO i preferab y ter sills. This Web is connected by angles 19 to the center sills and by suitable connection plates or angles 20 to the side walls of the car,

this web. The upper edge of web 18 passes through the apex flanges of inclined plates 22, which form the central cross-ridge of the car. These` plates extend from side to side of the car and, may be iianged at their ends and riveted to said side walls, as shown, or connecting-angles maybe employed, as is well known. The lower edges of these plates 22 are stiiiened by angles 23, and in addition stiiicningangles 24 may be riveted to the under side of the plates. Doors 25 may be hinged to the lower edges of the cross-ridge plates, the outer or closing edges of said doors being stiffened by angles26 in a wellknown manner. o stiiien the upper or hinged edge of the door, I provide the same with a strengthening-ridge 27, which may be embossed in the plate forming the door, as shown, or a strengtheningangle may be. attached to the door at this point, so as to offer an additional securing means for the hinge.

The ulpper side edges of the web 18 are y cut away to 'accommodate the ower edges of gusset-plates 28, secured to the side walls of the car, said lower edges of saidgusset-plates being riveted to the apices of the edge iianges, as'shown in Fig. 5.

By thev above construction it will be noted that the car, whilebeing light, is amply strong, and, further, that very little presswork is required.

I am aware that minor changes in the construction, arrangement, and combination of `the several parts of my device can be made andsubstituted for those herein shown and described without departing Jfrom the nature and principle of the invention.

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