lpplication filed June 10, 1901. Serial No. 63,904. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE 1, KING, a citizen of the United States, residing at the city of Detroit, count y of WVayne, State of Michigan, 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 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 partial top plan view of my improved hopper-bottom car. Fig. 2 is a sideelevational view of one end of the car. Fig. 3 is a top plan view of the underframing for one end of the car. Fig. 4 is a vertical sectional view through one end of the car. Fig. 5 is an enlarged detail view on line 5 5, Fig. 4. Fig. 6 is an enlarged detail sectional view on line 6 6, Fig. 4. Fig. 7 is an enlarged detail sectional view on line 7 7, Fig. 4.

This invention relates to a new and useful improvement in hopper-bottom cars designed especially for use in hauling loose loads or material in granular form, the object being to provide a car with a bottom made up of inclined sheets to accelerate the discharge of the load, the exit-openings for the load being con trolled by suitable doors.

Another object is to construct a car of the character described of structural or pressed steel, and in order to obtain maximum strength and rigidity with the least amount of dead-weight with respect to the carrying capacity of the car I utilize the side walls as plate-girders, which plate-girders also help form what might be termed the top chords of side trusses, the bottom chords of said trusses being preferably in the form of horizontally-arranged latticed girders supported at their ends by the body-bolsters of the car.

Another object is to take advantage of the arrangement and disposition of the hopperfioor sheets by utilizing said sheets to add strength and rigidity to the structure.

"With these objects in view the invention consists in the construction, arrangement, and combination of the several parts, all as will hereinafter be described, and afterward pointed out in the claims. i

In the drawings, 1 indicates the end sills of the car, and 2 the draft-sills, which draftsills preferably extend only to the body-bolsters.

3 indicates the body-bolsters, which are preferably continuous from side sill to side sill and I-shaped in section.

4 indicates the side sills, which are preferably in the form of channels with their flanges presented inwardly, said channels being riveted to the ends of the body-bolsters.

5 and 6 are top and bottom cover-plates the body-bolsters.

7 indicates connection-plates secured to the bottom flanges of the side sills, and under the outer edges of these connection-plates is arranged a transversely-disposed angle 8.

9 indicates angles preferably parallel to each other and to the side sills, which angles are arranged under the inner edges of the plates 7, and consequently these angles are on a lower plane than the bottom flanges of the side sills. These angles 9 carry connection-plates 10, and'the side sills carry connection-plates 11, said connection-plates being diagonally arranged with respect to each other for the attachment of lattice-bars 12.

13 indicates plates extending from the end sills back to and under the plates 7. These plates 13 are riveted throughout their length to the bottom flanges of the side sills. By preference the angle 8 is arranged under the plate 13, filling-pieces being employed where required. Plates 13 are preferably bent up at the edges of the plates 7, so as to lie against the bottom flanges of the side sills.

As shown in Fig-5, the web of the bodybolster is cut away to enable this plate to extend continuously without interruption from the end sill to the connection-plate 7. To secure the lower portion of the body-bolfor ster to the plate and the bottom flange of the side sill, I arrange an angle 3 thereunder, whose vertical leg is riveted to the web of the body-bolster. The side sill is secured to the end of the body-bolster by a corner connectionplate, the bottom flange of the side sill being received in the opening formed in the web of the body-bolster. The above construction is necessary where the body-bolster is deeper than the side sills. Of course where the bolster and side sills are of the same depth the plates 13 would be secured to the bottom flanges of each.

The center-plate and side bearings are preferably castings riveted to the bottom coverplate of the bolster, and as it is desirable to preserve the continuity of the bolster, especially at the central portion thereof, I do not remove any part of the bottom flanges or web for the reception of the king-pin, but make the center-bearing deep enough to enable the king-pin to.be introduced therein from the bottom and a cross-key inserted, which crosskey serves to hold the king-pin in its designed position. This cross-key passes through openings in the center bearings and a registering opening in the upper end of the king-pin, being headed at one end, and a cotter or split ring being introduced through the other to prevent its getting out of position.

14 indicates a transversely-arranged plate riveted to the side and draft sills in proximity to the end sills. 15 indicates plates riveted to the top flanges of the side sills and to the ends of the plates which they intersect, said plates 15 being preferably bent so as to pass over the transverse plate 14 and the top cover-plate of the bolster and to lie close against the top flange of the side sill, it" required. These plates 15 are provided with upwardly-extending marginal flanges practically throughout their entire length for the purpose of adding strength thereto. These marginal flanges at the inner ends of the plates 15 are preferably turned downwardly and riveted to the floor-sheet of the car-body.

The structure above described forms a very strong but light underframing of such character'that the inner truck-wheels may project upwardly into the space between the body-bolster and the angles 8 without detracting from the rigidity of the frame. The type of car to which this underframing is peculiarly adapted is that wherein the body of the car is low set. Consequently the underframing must be correspondingly positioned, and it is necessary in doing this to accommodate the trucks without sacrificing the strength of the underframe. The car shown in the accompanying drawings is designed to meet conditions of service and standards at present extant in Queensland, and therefore the standard draft-rigging in vogue on Queensland railways is here shown.

The side sills 4E, angles 9, and lattice-bars 12, before referred to, form horizontally-arranged latticed girders which, in addition to resisting buffing and pulling stresses, are also placed in tension by forming the bottom chords of the side truss-frames.

16 indicates the side walls of the car in the form of plate-girders which are supported over the body-bolsters by inclined stiffeningbraces 17. The lower edges of the side sheets are above the side sills, as shown, and said side sheets have angles 18 riveted thereto, which angles are oppositely inclined or arranged zigzag between the inclined stiffeningbraces 17. These angles and inclined stiffening-braces form a series of triangles or A- frames connected together at their upper ends by the side sheets and at their lower ends by the side sill member of the horizontal girders. This structure possesses great strength besides being extremely light. It has the elements of a trussed framing in that part of the top chord or compression member is in the form of a deep vertical web, which also forms the side wall of the car. The latticed girder acts as thebottom chord and under load is placed in tension, while the inclined braces 18 take the place of the usual vertical posts and diagonals commonly found in trussed frames.

Referring to Fig. 2, it will be noticed that the two inclined braces 18 nearest the bodybolster are connected to the side sill approximately in the transverse plane of the angle 8, and, further, that the angle 8 referred to serves as a transverse floor-beam by supporting the lower end of the inclined end floorsheets.

In the design shown in the accompanying drawings there are six angles 18 on each side of the car between the inclined stiffeningbraces 17, and the middle two of this set of angles are connected practically to a common point at their lower ends to the side sill. To brace the center of the car, I arrange an angle l9 exteriorly the side sheet, as shown in Fig. 2, and secure between the side Walls, in the plane of the angles 19, a tie-bar 20 in the form of two oppositely-arranged angles.

21 indicates angles riveted to the inner face of the side sheets and extending downwardly from a point opposite the angles 19 inwardly to the apex of the cross-ridge.

22 indicates a tie-plate riveted to the top flange of the side sill and extending inwardly to the side floor-sheet, to which it is also riveted. This tie-plate 22 is preferably opposite the central cross-ridge. 23 indicates a similar tie-plate for tying the top flange of the side sill and the side floor-sheet at a point intermediate the center of the car and the connection between the end of the side floor-sheet and the top flange of the side sill through the instrumentality of the inner end of the plate 15.

24-indicates the sloping end floor-sheet, which is provided with downturned flanges at the sides of its upper portion, which are riveted to the lower inclined edges of the side floor-sheets.

25 indicates the end sheet of the car.

Corner-posts 26 connect the side and end sheets and the side and end sills. The floor of the car-body adjacent the corner-posts is ICC partially supported by a frame 27, composed of members so arranged as, in addition to partially supporting the floor of the car, to resist lateral swaying of what might be termed the overhanging body portion.

28 indicates a floor-support extending transversely the underframe to which it is secured, the ends of said floor-support projecting outwardly beyond the car-body and being secured to the inclined stiffening-braces. As shown, I prefer to form this floor-support of a sheet of metal appropriately bent or flanged, the bottom flange being riveted to the top coverplate of the bolster, while the upper flange thereof is riveted to the floor-sheet.

29 indicates the sloping side floor-sheet, sometimes designated as the side hoppersheet. This sheet 29 has its upper edge riveted to the lower edge of the side sheet 16 and extends inwardly and downwardly over the angle 9, to whose vertical leg it is riveted. The vertical portion of this sheet 29 forms a vertical wall of the exit-opening for the load, it being further strengthened by an angle 30. The lower inner end of the end floor-sheet is flanged downwardly and reinforced by an angle 31. To the angles 30 are secured the guides for the horizontally-movable doors 32, said doors being provided with racks on their under sides, with which engage pinions secured to an operatingshaft, which shaft is provided with a crank-handle at its extremity or extremities.

33 indicates transversely-extending angles secured to the lower edges of the vertical portions of the side floorsheets 29.

34 indicates a ridge-sheet which is flanged over the ngle 33 and riveted thereto, said ridge-sheet between the vertical portions of the side sheets 29 being flanged downwardly and riveted thereto through the medium of such flanges, while above the vertical portions or throughout the inclined portions of the sheets 29, traversed by the ridge-sheet, said ridge-sheet is flanged upwardly, and through the medium of such flange is riveted to the inclined portions of the sheet 29. The upper edge of the ridge-sheet is flanged vertically, through which flange it is riveted to its companion.

35 indicates a partition-plate extending across the car in the transverse plane of the apex of the cross-ridge. This partition-plate is secured in position by being introduced between the vertical flanges at the upper edges of the cross-ridge between the angles 21 and between the angles or tie-rods 20. It is obvious that this partition can be extended up above the top of the side walls of the car for the purpose of enabling the car to carry a mixed load, keeping said mixed load separated, whereby the contents of one end of the car may be discharged through the hopperopening without affecting the load at the other end of the car. Constructed as shown in the drawings this partition-sheet not only adds strength to the side walls, but ties said side walls together, preventing lateral bulging thereof, and combined with the ridge-sheets forms an effective and rigid support therefor and for the center of the car.
