RAILWAY CAR.

Application filed January 26, 1923. Serial No. 614,959.

To all whom it may concern:

Be it known that I, BYERS W. KADEL, a citizen of the United States, residing at Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Railway Cars, of

which the following is a specification.

This invention relates to car construction and has for its principal object to provide an no improved form of body bolster. A more specific object is to provide a body bolster adapted for heav capacity cars and one which may be ma e of a steel plate. A still further object is to provide a heavy capacity 16 body bolster adapted to be located within th lading space of the car. With these and other objects in view the invention consists of the formation, combination and arrangement of parts as will be herein described and claimed.

In the accompanying drawings which show a preferred form of the invention, Figure 1 is a fragmentary side elevational -view of a freight car having a body bolster constructed in accordance with the principles of the present invention. Figure 2 is a transverse vertical sectional view taken substantially on the line 2-2 'of Figure 1 and showing the body bolster extending from side to ac side of the car. Figure 3 is a longitudinal vertical section taken through the bolster, this view being taken substantially on the line 38 of Figure 2. Figure 4 is a fragmentary horizontal sectional view taken through as a portion of the bolster near the side of the car, this view being taken substantially on the line 44 of Figure 1. Figure 5 is a fragmentary vertical sectional view taken through the bolster substantially on the line as 5-5 of Figure 2. Figure 6 is a fragmentary side elevational view'of a car having a bolster of a slightly modified construction and Figure 7 is a partial transverse vertical sectional view through the same, this view beas ing taken substantially on the line 7-7 of Figure 6. Figure 8 is a flat face view of the flanged blank from which the bolster of either of the two embodiments is made. This view shows in dotted outline the approxiso mately rectangular plate from which the bolster is to be flanged. and in full lines the flanged blank, before being folded and before the rivet holes are punched in it. Figure 9 is an edge view of the blank and Figure 10 is a sectional view thereof, this view being taken on the line 10-.10 of Figure 8. Referring to these drawings the car is shown as having sides 1 and a floor 2 with the customary lower chord angles 3 which serve to frame the car sides and floor together. The car is also shown as supplied with the customary longitudinal center sill construction which consists of channels 4 and a top cover plate 5 riveted to them. The floor 2 may be disposed between the top of the cover plate 5 and the bottom'of the bolster. Extending across the interior of the car from side to side and above the center sill construction is a body bolster 6. This is provided to carry the load from the car sides inwardly to the center sill construction where it passes in turn to the customary center bearing plateor to other means for transferring the load of the car body to the truck.

The body bolster of this construction is formed of a substantially rectangular steel plate which may be of the contour indicated by the dotted outline 7 in Figure 8. The edges of the plate are turned at right angles to the general plane of the plate to form outstanding marginal flanges 8. Corrugations 9 and 10 are also pressed into the plate at the same time the marginal flanges are formed and these serve, in service, to stiffen the finished bolster at certain points of high concentration of loading. The corners of the flanged plate are provided with slightly offset portions 11, which in the finished bolster form spaces to accommodate the continuous angles 3 when the bolster is applied to the car.

After Hanging as above described, the bol- .ster plate is folded along a longitudinal bend line into U shape as shown in sectional views such as 3 and 5, thereby producing duplicat bolster halves 26 and 27. The plate is so folded as to throw the flanges 8 on the outer faces on the folded bolster and these flanges are thereby thrown into position to form means for riveting the ends of the bolster to the car side and for attaching the floor plate to the bottom of the bolster. Rivets 12 pass through these end flanges and through the sides of the car and rivets 13 may be arranged at the offset flanges 12 to' pass through these flanges and through the car sides as well as through the vertical legs of the angles 3. Rivets 14 ]pass through the bottom flanges and throng the floor plate and rivets 15 may be similarly located in the offset portions 11 to pass through these flanges and through the horizontal legs of the angles 3 and through the floor plate. Rivets 16 may pass through the bottom flange of the bolster and through the floor plate, the center sill cover plate 5 and through the top flanges of the channels 4. Intermediate rivets 17 may also pass through the bottom flan es, the floor plate and the cover late 5. he corrugations9 are so an ranged in the blank that when the bolster is completed these will extend upwardly from the bottom edges of the bolster toward the top of the bolster and will be in substantial ali nment with the center sill channels 4. Th1s is desirable because of the concentration of the load that occurs in line with the members such as the channels.

Such car construction is also ordinarily provided with side bearings as shown at 18. These may be attached to the body bolster b means of rivets 19 to pass through the si e bearings and through the floor of the car and through the bottom flanges of the bolster. The corrugations 10 are formed in a similar man- ,ner to the corrugations 9 and are located immediately above the side bearing to stiffen the bolster at these points of impact.

Cars'of this type are frequently supplied with interior wing plates 20 immediately above the bolster. In the present embodiment these are shown as formed of flanged steel lates which are attached to the car sides y means of rivets 21 with the foot of each wing plate carried down and bent around the top of the bolster and attached thereto by means of rivets 22. A tie plate 23 may also be attached to the wing plate just above the top of the bolster by means of rivets 24 and this preferably is bent down around. the other side of the bolster and attached thereto by means of rivets 25. This gives a double line of rivets to hold the foot of the wing plate to the bolster and one plate serves'to prevent the bending of the other.

In the embodiment shown in Figures 1 to 5 the flanges at the ends of the bolster continue in upright fashion around the top of the finished bolster. .In Figures 6 and 7 it is shown how this flange may be turned over to lie in flat fashion against the top of the bolster instead of standing upright therefrom. Either practice may be followed in bending the bolster alongthe longitudinal axis.

I have thus described a preferred embodiment of my invention. Other embodiments are contemplated within the scope of the appended claims without departing from the spirit thereof.

Vhat is claimed is:

1. A body bolster for railway cars formed of a steel plate having marginal flanges along its sides and along its ends, the same being folded along a longitudinal line to form spaced sides with the flanges extending outwardly from the sides.

2. A body bolster for railway cars formed of a steel plate folded along a longitudinal line to provide spaced sides integrally connected at thetop of'the bolster, and integral flanges formed along the side edges and at least a portion of the end edges of the bolster an embodying attaching means, the flanges along the end edges being continuations of the side edge flanges.

3. A body bolster for railway cars formed of a steel plate folded along a longitudinal line to provide spaced sides integrally connected at the top of the bolster and with attaching flanges at some of the edges of the bolster, and vertically arranged corrugations formed in the sides of the bolster.

4. A body bolster for railway cars formed of a steel plate folded along a longitudinal line to provide spaced sides integrally connected at the top, and having holes formed in the ends of the bolster near its top arranged for the attachment thereto of wing plates.

5. A blank for a body bolster consisting of a steel plate provided with upright marginal flanges along its sides and ends, all of said flanges being turned in the same upstanding direction.

6. A blank for a body bolster consisting of a steel plate provided with upright mar ginal flanges along its sides and ends, there being offsets in the lines of the flanges at the corners of the blank.

7. A blank for a car bolster consisting of a steel plate provided with upright marginal flanges along its sides and ends, and corrugations extending from some of the flanges inwardly toward the center of the blank.

8. A blank for a car bolster consisting of a steel plate provided with upright marginal flanges along opposite sides, and corru ations formed in the plate the same being d isposed transversely of the line of said flanges and'extending from th said flanged edges toward the center of the blank.

9. A blank for a car bolster consisting of a steel plate with upright flanges along 0pposite sides. and corrugations in the plate extending from the flange at one side t0- ward the flange at the other side of the blank.

In testimony whereof I aflix m signature.
