CAR CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 728,800, dated May 19, 1903.

Application filed April 8, 1901.

T0 at whom it may concern.-

Be it known that I, GEORGE I. KING, a citizen of the United States, residing at the city of Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Car Construction, 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 top plan view of myimproved car, part of the floor being removed to show the underframing. Fig. 2 is a side elevational view, partly in section, the plane of the section being on line 2 2, Fig. 1. Fig. 3 is an enlarged cross-sectional view. Fig. 4 is a top plan-view of a modified form, part of the flooring being removed to show the underframing. Fig. 5 is a cross-sectional view through the same. Fig. 6 is a longitudinal sectional view through one end of the car, and Fig. 7 is a side elevational view of one end of the car.

This invention relates to a new and useful improvement in car construction, designed particularly foruse in connection with the type of car known as low-side gondola, though it is obvious that features of the invention may be used in connection with other types of cars.

The object of the present invention is to simplify the construction of railway rollingstock, the material entering into the device being, preferably, structural steel, the car as an entirety being comparatively light and extremely rigid, capable of carrying heavy loads and withstanding shocks and jars, to which devices of this character are subject.

With this object 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.

In the drawings, A indicates the end sills, which are preferably channels with their flanges presented outwardly.

B indicates the side sills, which extend from end sill to 'end sill and are attached Serial No. 54,856. No model.)

0 indicates connection-plates riveted to the inner faces of the side sills and projecting below the said side sills.

0 indicates the bolster-beams, which are preferably I-shaped in section, said beams being continuous from side sill to side sill and attached to the side sills and the connection-plates c by the use of angle connectionplates and appropriate rivets.

D indicates draft-sills which extend between the bolster-beams and the end sills. These draft-sills are deeper than the end sills, but not as deep as the bolster-beams. The end sills carry castings a.,which extend therebelow and to which the draft-sills are connected by the employment of angle connection-plates and rivets, the upper faces of the end, side, and draft sills and the bolsterbeams being substantially on the same horizontal plane. The draft-sills are arranged a sufficient distance apart to accommodate the draft rigging, the coupler shank passing through an opening in the depending portion of the casting a. Connection-plates d are employed to attach the inner ends of the draft-sills to the bolster-beams, as shown in Fig. 2, said connection-plates extending below the draft-sills, so as to be flush with the bottom flanges of the holsters. Of course these connection-plates are notched to accommodate the bottom flanges of the bolsters and, as shown in Fig. 2, have their lower edges flanged, as at d, to receive rivets by which said connection-plates are attached to the bottom cover-plates of the bolsters.

E indicates the bottom cover-plates of the bolsters, which are riveted to the lower flanges of the connection-plates d and to the bottom flanges of the bolster-beams and also to the bottom flanges of the center sills. These bottom cover-plates are preferably polygonal in shape, as shown in- Fig. 1.

F indicates the center-sills, which are preferably I-shaped in section, said center sills preferably being of a depth coincident with the depth of the body-bolsters, to which they are attached by suitable corner connectionplates, as shown in Fig. 3. These center sills extend from bolster to bolster and are spaced more widely apart than are the draft-sills, the object of said wide spacing being to divide the floor-space between the bolsters into panels of approximately equal area. By so widely spacing the center sills the necessity for intermediate longitudinal sills is dispensed with, the load between the bolsters being carried by the side and center sills. The bolsters are equipped with the usual center and side bearings, the latter not being shown in the drawings.

The floor of my improved car is preferably composed of sheets of steel, though it is obvious that the nnderframing above described can be usedin connection with a wooden floor. The floor shown in the accompanying drawings consists of end sheets 1 and 2, which are riveted to the top flanges of the end, side, and-draft sills and the top flanges of the bodybolsters, said sheets terminating a short dis tance within the body-bolsters, and side floorsheets 3 and 4, which are riveted at their outer edges to the top flanges of the side sills and-at their inner edges to the top flanges of the center sills. The ends of these side floorsheets, as well as a portion of the inner edges of the end sheets, are riveted to cover-strips preferably arranged under the floor-sheets,

said strips being indicated by dotted lines in Fig. 1, a butt-joint being thus formed, and 5 indicates the center floor-sheet, whichis riveted to the inner edges of the side floor-sheets and the top flanges of the center sills, the ends of said center floor-sheetbeing riveted to the middle portions of the end floor-sheets. Angles G may be employed at intervals to support the side and center floor-sheets, as shown in Figs. 1 and 2.

G indicates diagonally-arranged braces, preferably in the form of angles, which are riveted to the under side of the end floorsheet 1, said braces extending from the junction of the side and end sills inward toward the junction of the draft-sills and bolster.

H indicates channels arranged above the side sills, said channels forming the side walls of the car. These channels have their bottom flanges riveted to the top flanges of the side sills, the side and end floor-sheets being interposed therebetween, as shown in Fig. 3. I prefer to cut the channels H short at the end of the car, so as to leave a foot-space, as shown in Figs. 1 and 2.

The end walls of the car are in the form of channels, (indicated at 1,) which are secured to the side-wall channels by suitable corner connection-plates. Gusset'plates J may be used to brace the side channels, as shown. Corner connection-plates K may be riveted to the top flanges of the end and side walls.

From the above it will be seen that the structure is simple, the floor-frame having ample strength to sustain the weight of the car and its contained load. Repairs may be readily and easily made, and in the event of damage to the draft-sills these can be quickly replaced, as they extend only from end sill to bolster. The channel side walls, in connection with the side sills, serve substantially as plate-girders, the side floor-sheets assisting to increase the available section thereof. The manner in which theseparts are assembled permits the general use of a machine-riveter, which materially reduces the cost of construction. The continuous body-bolster in the form of a commercially-rolled I-beam is extremely simple and efficient. Being in one piece, it is strong, the cover-plates being used more as connection-plates to tie. the floorframe together than as bolster cover-plates in the sense that such cover-plates are most usually employed. It will also he observed that the sheet-steel floor being supported between tbe bolsters by two evenly-spaced center sills no additional main-floor supports are required. The cost of construction is thus cheapened and the dead weight reduced. Moreover, the continuous attachment of the side and center floor-sheets to the top flanges of the sideand center sills obviates the necessity for using diagonal members between the bolsters. The end sheets of the floor serve as the top cover-plates for the bolsters, tying the underframing, and in order to strengthen this plate against buckling, as when a pushpole is used, diagonally-arranged angles L may be riveted to the under face of this end floor-sheet, as shown in Fig. l. y

In Figs. 4, 5, 6, and 7 I have shown myimproved floor-frame having deeper side sills than are shown in the sheet of drawings just above described. By making the side sills deeper, as shown in Fig. 5, the strength of the floor-frame is increased, enabling the channels H to be dispensed with, thus producing the type known as the flat-car. In this construction the floor-sheets are similarly arranged, as heretofore described, with the exception that rivets are preferably countersunk, and instead of using a single row of rivets to secure the plates 3, t, and 5 to the center sills, the center plate overlapping the inner edges of the side plates, butt-joints are provided, the rivets passing through the flanges at'the top of the I-shaped center sills and the I-shaped bolster-beams. My improvement is thus well adapted for use as a flatcar, and by using countersunk rivets in the floor-sheets a smooth floor results.

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