LOW-SIDE GONDOLA CAR.

SPECIFICATION formingpart of Letters Patent No. 727,619, dated May 12, 1903.

Application filed May 28, 1902.

T0 ctZZ whom it mar concern.-

Be it known that I, JOHN M. HANSEN, a resident of Pittsburg, in thecounty of Allegheny and State of Pennsylvania, have invented a newand usefulImprovement in Low-Side Gondola Cars and I do hereby declare the following to be a full, clear, andexact description thereof.

My invention relates to metallic. underframes for railway-cars, and more especially to underframes forcars provided with a flat bottom or floor.

The object of myinvention is to improve metallic car-underframesin details of construction, which will be hereinafter described and claimed.

In the accompanying. drawings, Figure 1 is a plan view of one-half of the car, the lower portion of said figure showing the floor-plates removed. Fig. 2, is a longitudinal section through the car on the line 2 2, Fig. 1. Fig. 3 is a transverse section through the bolster. Fig. 4 is a transverse section on the line 4 4:, Fig. l; and Fig. 5 on the right-hand portion is a transverse section on the line 5 5, Fig. 1, and on the left-hand portion is an end View of the car.

I have shown my underframe applied to a gondola car havinglow'sides; but it will be understood that the. underframe can be used with any car having a flat bottom. The car shown is of the type having center sills, but having no side sills, the sides of the carbeing formed as plate-girders, which assist in supporting the load. The center sills 1. are channel-shaped structures, preferably rolled channel-beams, as shown, and are placed with their flanges preferably projecting outwardly. These center sills project beyond the bodybolsters 2 and have connected thereto outside of the body-bolsters the draft-sills 3, which extend to the end. sills 4. The sides of the car are formed of metal plates 5,which extend, preferably, continuously from bodybolster to body-bolster, as shown, and other plates6, which extend from the body-bolsters to the ends of the car. The plates 5 and 6 lie in the same plane, and their meeting edges are united by means of the trough-shaped stakes 7, having outwardly-projecting flanges to which the plates 5 and 6 are riveted. Inside of the plates opposite the stakes are Serial No. 109,2?77; (No model.)

cover plates or welts 8, which reinforce the joint and exclude the lading from the trough of the stakes. The side plates are stifiened by means of angle- rails 9 and 10, riveted, respectively, to thetop and bottom edges of said plates. These angle-rails are shown as having their vertical flanges lying inside of the side plates and their horizontal flanges projecting "outwardly; but their vertical flanges may lie inside or outside of the side plates, andtheir horizontal flanges may project either inwardly or outwardly, as desired. The stakes 7 lie between the upper and lower flanges of these angle-rails, and the side plates are stiffened at intervals by sections of anglebars 11, riveted .to the outer face and extending between the flanges of the top and bottom angle-rails. The side plates, together with the top and bottom angle-rails and stiffeningangles 11, form, in effect, plate-girders, which assist in supporting the load. Stake-pockets 12 are secured at intervals to the side plates on the inside of the car.

The body-bolsters comprise top or tension members 15 and bottom or com pression members 16 and web-fillers 17. The top members or cover-plates, as I term them, extend throughslots 18, out in the webs of the center sills, and extend nearly, but not quite, out to the sides of the car. The bottom or compression members lflare in the form of plates and extend continuously underneath the center sills, nearly out the end of the bolster. The web-fillers 17 are composed of two channel-shaped members formed, preferably, of pressed metal,havin g flanges on their upper and lower sides and inner ends, said members being placed back to back, as shown, and united by means of the top and bottom plates 15 and 16, which are riveted :to the flanges of the members 17.' The flanges on the inner ends of these chan'nel members are riveted to the center sills. At their outer ends the channel members are somewhat offset or spread apart, as'shown' in Fig. 1, and in the space thus formed are located two of the flanges of two angle-bars 21, the other flanges of .said bars projecting outwardly at 22 and serving as a convenient means for securing the sides of the cars thereto. The inwardly-projecting flanges of the angle-bars 21 are secured between the members 17 by means of rivets, and the other flanges of said anglebars are secured to the sides of the car by the same rivets which secure the side plates to the flanges of the stakes 7. In place of the two angle-bars 21 a single T-bar may be used.

Extension-plates 23 are riveted to the lower flanges of the web-fillers beyond the ends of the compression member 16 and project outwardly beyond the end of the bolster and form brackets upon which the angle-rails rest and to which they are secured. Between the center sills, in line with the web-fillers 17, is a brace 24, preferably formed of cast metal and riveted to the center sills, as shown, this brace being provided with a boss 25, having a vertical opening for receiving the center pin. The body-bolsters are of less depth than the center sills, and sections of Z-bars 27 are secured to the bolsters, preferably by one of the rows of rivets which secures the top coverplate to the webaillers 17, these Z-bars serving as supports for the side floor-plates 28. The floor-plates have their outside edges turned upward to form flanges which are riveted to the side plates of the car, and their inner edges are riveted to the upper flanges of the center sills. Central cover or floor plates 29 overlap the side floor-plates 2S and are riveted to the center sills. The floorplates are supported at intervals by transoms or diaphragms 30, which are formed of sections of channel-bar and are secured to the center sills and side plates of the car by angle-pieces 32. between the center sills, opposite some of the diaphragms 30, are braces 33, which likewise are formed of sections of channel-bar and secured to the center sills by angle-pieces 34. At the center of the car the nnderframe is tied together by diaphragms, which comprise sections of channelbar 37, connected to the center sills and sides of the car by angle-pieces 38 and continuous transverse tie members 39, extending underneath the center sills from side to side of the car. These tie members 39 are connected to the channel members 37 by means of one or more web-plates 40, four such plates being shown on each side of the car, although a greater or lesser number may be employed, as necessary, or, if desired, a single continuous plate might extend from the center sills tothe-side of the car. The tie members 39 Zire shown as angle-bars having their horizontal flanges bearing against the bottom of the center sills and their vertical flanges having the web-plates 40 secured thereto. These angle-bars 39 project beyond the sides of the car and form brackets 41 for supporting the sides of the car. Between the center sills, opposite the diaphragms 37,are braces 42,formed of a plate sheared to shape and having a flange formed at its upper edge, which supports the floor-plates. This brace-plate is connected to the center sills by angle-pieces 43, and its lower edge projects downwardly, as at 44., below the center sills and is riveted to the vertical flange of the angle-bar 39. The knee-pieces 4 on the opposite edges of the brace 42 lie on opposite sides thereof, as shown in Fig. 1, the object of this being to permit the center sills being made exactly identical and not one the reverse of the other. One set of rivets only is necessary for uniting the anglepieces 38 and 44 to the center sills, as indicated in Fig. 1. The same construction is followed with reference to the angle-pieces and 34:, thus making a considerable saving in rivets.

The draft-sills 3 are channel-shaped sections formed, preferably, from pressed plate and have their upper flanges cut away at their inner ends, as shown at 45, and their webs lying against the inner faces of the webs of the channel center sills and riveted thereto. Their lower flanges lie underneath the center sills, as indicated in Fig. 2, and may also be riveted thereto. These draftsills have riveted thereto the draft-lugs 4:6 and are connected by transverse tie-plates 47. The outer ends of the draft-sills are connected by means of angle-pieces 49 to the end sill 50. The latter is formed of pressed metal and is of general channel shape, having the top flange lying on top of and riveted to the floor-plates, said top flange being of varying width, as shownin Fig. 1. The vertical web of the end sill is provided with an opening 52 for the shank of the draw-bar and has connected thereto the draw-bar carrier 53. The car is shown as provided with a wooden drop end 55; but this is not material.

The car-frame described is very simple and strong and is composed mostly of commercial-rolled steel,only a very fewspecial shapes being necessary.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-
