To all whom, it mol/y 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 acertain new and useful Improvement in MetalliC-Car Construction, of which. the following is afull, clear, and exact description, such as will enable others skilled in the art to which 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 Cross-sectional view through a car constructed in accordance with my invention. Fig. 2 is a sectional view on the line 2 2 of Fig. 1. Fig. 8 is a sectional view on the line 8 8 of Fig. 1, and Fig. 4 is a per- .spective view showing the construction of the gusset.

This invention relates to metalliC Cars, and particularly to freight-cars of the type in which is employed a hopper-bottom.

The object of the invention is to provide means for'bracing the entire car-body and to do this with a car of minimum weight.

Another object is to reinforce the sides of the car, So as to stiffen them and assist in resisting the strains to which the sides Would be subjected under load, and a further object of the invention is to assist in tying in the sides to the underframe.

Other objects and adVant-ages, as well as the novel details of construction of this invention, will be more specifically referred to hereinafter, it being understood that changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit of my invention or sacrificing any of the advantages thereof.

Referring now to the drawings, 1 designates the center sill, having two members of channel form with outwardly-disposed flanges, the Cross-bearers 2 being illustrated as comprising Channels secured at their inner ends to the webs of the Center-sil] Channels by angieplates 3, and these Channels are secured to the plate-girder sides 4 by angle-plates 5. The upper edges of the plate-girder sides have integral outWardly-disposed edges comprising fianges 6. Resting on the top of these outwardly-disposed edges 6 are the webs of channels 7, which webs are riveted to the fianges 6, and the flanges of the Channels 7 depend from the webs. The plate-girder sides 4: eX- tend below the cross-bearers 2 and below the center sills and have outwardly-projecting flanges 8, which serve as the bottom Chords of the plate-girder sides, the upper Chords being the Channels 7 in combination with the outwardly-turned fianges 6.

9 designates a cross-bearer arranged interimediate the ends of the car and positionedV by angle-plates 13. The lower flanges of the Channels are shown as depending below the bottoms of the sides and rest on bracketplates 14;, ,which are secured to the sides of the Car and have their ends provided With inturned fianges 15, which are Secured to said bottom fianges.

A gusset-plate 16 is arranged at the center of the car and provided at one edge with oppositely-disposed fianges 17 and 18, which are secured to the plate-girder side. The flange 17 forms a part of the gusset, while the fiange 18 is a flange of an angle 19 riveted to the gusset and to the plate girder side. The flanges 17 and 18 extend down to the fioor, where they terminate. The gusset continues through the fioor and is secured to the web of the channel cross-bearer 2 and is interposed between the webs 10 and ll of the Crossbearer 9, so that the rivets 20 secure the Channels 10 and ll together and at the same time secure the lower portion of the gusset therebetween. a

sets 16Et extend only to the Cross-bearer or fioor-support, to which they are riveted by rivets passing through the webs of said fioorsupport. The fioor-Sheet 21 extends over the bottom of the Car and is fastened to the fioorsupports in any suitable manner, and the edges of .the fioor-Sheet at` the sidesare upturned and fastened to the plate-girder sides of the Car. A Cover-plate 22 is riveted to the top flanges of the channel Center-sill members by rivets, which pass through the fioor-sheet and through the top flanges of said channels.

At the other portions of the car the gus- V On the outside of the car are stakes or posts 28, which are of pressed shapes and have oppositely-disposed fianges 24 and 25, which are riveted to the sides of the car by rivets which secure the fianges of the gusset to the plategirder sides, and in order to additionally strengthen the car adjacent the stakes inserted plates 26 and 27 may be used, which plates are interposed between the fianges of the gussets and the car sides and between the flanges of the stakes and the car sides. The upper ends of the stakes have flat extensions 28, with outturned extremities 29, which' are riveted beneath the outwardly disposed fianges 6 of the sides, so that the whole structure will be braced against the strains to which a car of this type will be subjected.

In Fig. 4 I have illustrated a gusset 30 in most respects similar to the gusset 16a, but in this form the base of the gusset or bottom thercof is provided with an outturned fiange 31, which is riveted to the floor, and the hypotenuse of the angle of which the gusset consists is provided with a fiange 32, integral therewith so as to protect the edge of the gusset against injury from contact with the load. This fiange 32 will prevent injury to the gusset under certain conditions-as, for example, when pig-iron ingots are thrown into the car.

33 designates one end of the car, which may be secured to the underframing and plategirder sides in any preferred manner, the ends of the car being preferably provided with channel upper chords and stakes.

From the foregoing it will be seen' that a car constructed in accordance with the one just described will possess a maximum strength and will be capable of resisting all the strains to which it would ordinarily be subjected, and that by providing the gussets and securing them to the underframing the rivets which fasten the gussets to the sides will be under i tension, and thus have a tendency to resist any bulging of the sides from any cause.

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

1. In a metallic car, the combination of plate-girder sides, floor-supports connected to the center sill and sides and fiush with the tops of the center-sill members, floor-sheets connected to all of said parts, and gussets having oppositely-disposed fianges connected to the sides of the car, one fiange of which is a part of an angle and the other flange being integral with the gusset, the bottom portions of said gussets being connected to the floor-supports; substantially as described.

2. In a metallic car, the combination with a center sill, cross-bearers carried by said center sill, plate-girder sides connected to the cross-bearers, gussets connected to the crossbearers and sides, the parts of the gussets adjacent the sides having right-angularly bent edges comprising fianges secured to said sides, and angle members carried by the gussets and alining with the fianges and also secured to said sides; substantially as described.

3.
