RAILWAY CARS FOR TRANSPORTING CYLINDRICAL OBJECTS Filed Sept. 11, 1962 5 Sheets-Sheet 5 in mm FIG. 4 Mia ZMQZF ammw ATTORNEY5 United States Patent 3,186,357 RAILWAY CARS FOR TRANSPORTING CYLINDRICAL OBJECTS Stanley H. Fillion, Scarsdale, N.Y., assignor to Waugh Equipment Company, Salisbury, Md., a corporation of Maryland Filed Sept. 11, 1962, Ser. No. 222,914 8 Claims. (Cl. 105-367) This invention relates to railway cars and is concerned more particularly with a novel railway car, on which heavy objects of cylindrical shape may be transported without damage and without the use of expensive blocking material. The new car may be profitably used in the carriage of tanks, coils of metal strip, and other objects of similar shape, and, since all the advantages of the car are realized in its use for transporting coils of metal strip, a form of the car primarily for such use will be illustrated and described in detail for purposes of illustration.

Coils of wide steel strip, such as are used in the manufacture of automobile bodies, are of great weight and their transporation without damage has heretofore presented difiicult problems. In some instances, they have been mounted on skids of the pallet type and shipped in insulated box cars, in which the skids are anchored in place by means of expensive blocking material. Powerful lift trucks are then required to load the skids in the cars and remove them. As an alternative, the coils have been placed in cradles attached to skids and the skids have been loaded on cars of the gondola type, provided with resilient end butters intended to cushion the movement of the skids. While this arrangement avoids the necessity of providing costly blocking, the weight. of the loaded skids is so great that the springs of the buffers are frequently damaged by movement of the skids on the car floor.

The present invention is, accordingly, directed to the provision of a railway car for the carriage of coils of metal strip and like heavy cylindrical objects, which transports the coils without damage and in a position facilitating their loading and unloading and does not require the use of expensive blocking material. The new car is provided with an underframe which includes a hollow longitudinal center sill, bolsters, and major side sills resting on the bolsters inward from their ends and extending above the level of the top of the center sill. The coils are carried in a cradle, which rests upon the center sill and is supported by members attached to the side and center sills. A movable draft and butting column is mounted Within the center sill and its movements relative to the center sill are resisted by a long travel cushioning mechanism. With the construction described, the coils are carried in a cradle, which is an integral part of the car structure, and shocks in buff and draft applied to the couplers are absorbed by the cushioning mechanism. As a result, the coils are transported without damage and only light cross-bars are used on the cradle to separate the coils.

For a better understanding of the invention, reference may be made to the accompanying drawings, in which FIGS. 1a, 112, and 10 form a fragmentary longitudinal vertical sectional view of a car embodying the invention;

FIG. 2 is a transverse sectional view on the line 2--2 of FIG. la;

FIGS. 3 and 4 are transverse sectional views on lines 33 and 44 of FIG. 10; and

FIG. 5 is a transverse sectional view on the line 55 of FIG. la.

The railway car shown in the drawings has an underframe which includes a hollow longitudinal center sill formed of a pair of Z-bars 11 disposed with their upper flanges opposed and spaced and a cover plate 12 closing the space between the edges of the flanges. Near the ends of the car and overlying the trucks are bolsters 13 comprising the usual box sections 14 extending outwardly from the center sill, the sections having a common cover plate 15, which extends across the sill between spaced sections of the cover plate 12. The sections 14 of each bolster are connected by a center casting 16 which extends across the open bottom of the center sill and, at intervals between the bolsters, I-beams 17, which are parts of crossbearers, extend across the bottom of the center sill and are attached to pads 18 secured to the lower flanges of the center sill. A major side sill 19 of l-beam form is mounted on and secured to the tops of the bolsters 13 inward from their ends at each side of the center sill. The major side sills extend substantially from one end of the car to the other and their top flanges 2t) lie in a common plane lying substantially above the level of the top of the center sill 10. The sills 19 have relatively narrow end sections 21 overlying the bolsters and, inward from the end sections, each sill has connecting sections 22 increasing in width to a middle section 23, the lower flange 24 of which rests upon and is secured to the tops of the beams 17. An angle bar 25 is attached to the top of each major side sill along its inner edge with one flange of the bar extending vertically and the other horizontally outward to overlie the sill. Minor side sills 26 extend outwardly from the ends of the bolsters to the ends of the car and are connected by an end sill 27.

A draft and bufiing column 28, which is formed of a pair of Z-bars 28:: having their top flanges opposed and secured together, extends through the center sill from end to end and is supported on the center castings 16 and the beams 17. At its ends, the column is provided with key slots having reinforcements 29 and a key 30 in each slot connects the shank of a coupler to the column. Inward from each key slot, the column encloses a cushioning unit made up of a plurality of rubber springs 31 lying between follower plates 32, 33. The front followe-r plate 32 is engaged by the shank of the adjacent coupler and the rear follower plate 33 abuts a pair of draft lugs 34 secured within the column to the opposed vertical surfaces thereof.

The endwise movements of the column relative to the center sill are resisted by a long travel cushioning mechanism which may be of various types and has a travel of at least 10" and, preferably, of about 20". The mechanism shown is of the construction disclosed in MacCurdy Patent 2,911,113, issued November 3, 1959, and it includes a stack of movable friction plates 35 extending lengthwise of the column and having enlarged ends 35a with lateral extensions engaged on their inner sides by stop lugs 36 secured in pairs at opposite ends of the stack of plates to the inner opposed surfaces of the column. Stationary friction plates 37 extending transversely are interleaved with the plates 35 and are secured within a yoke forming part of a friction box 38. The top 39 of the yoke extends through an opening in the top of the column and is attached to a plate 40 secured to the top flanges of the center sill. The bottom plate of the stack of movable plates 35 rests upon a pair of aligned plates 41, 42 having oppositely inclined plane bottom surfaces 41a, 42a, respectively. The plates are mounted between stop bars 43, 44 secured to the opposed inner faces of the column and the surfaces 41a, 42a of the inclined plane plates engage the top of a piston 45, which extends into a dashpot cylinder 46 attached to the friction box 38. Upon movement of the colurnn relative to the sill in either direction from the central position of the column, one or the other of the inclined plane plates 41, 42 causes a downward movement of the piston into the cylinder and, at the same time, the friction plates are squeezed or compressed together.

The cushioning mechanism includes a restoring spring 47 enclosing a link 48 attached at one end by a pin 49 to a projection 50 on one of the center castings lid. The link passes through follower plates 51a, 51b at the ends of the spring and engaging stop plates 52a, 2b on the opposed faces of the column and has a collar 53 fast thereon and bearing against the outer face of the follower plate 51b. With this arrangement, the movement of the column relative to the sill in either direction causes compression of the spring 4-3 and the spring acts to restore the column to its central position after release of the force which caused the column movement.

' A cradle of trough shape is formed as an integral part of the car structure and the cradle includes a pair or" downwardly convergent floor sections 54 extending lengthwise of the car and each usually including a number of planks 55 lying in a plane and having tongue and groove connections. The floor sections extend from the tops of respective major side sills to the top flanges of the bars 11 of the center sill id and the cover plates 15 of the bolsters. The sections are supported by supporting members disposed at intervals lengthwise of the car with some of the members lying above the bolsters, others forming parts of crossbearers, and the remainder out of vertical alignment with both the bolsters and crossbearers.

At the bolsters, the supporting members for the floor sections are diaphragm plates 56 which are secured by Welding to the top and bottom flanges and the webs of the major side sills 19, the angle vertical flanges of the bars 25, and the cover plates 15 of the bolsters. The diaphragm plates have inclined top edges with lateral flanges oz: serving as parts of the respective floor sections. By securing the plates 56 rigidly to the sills 19, the angle bars 25, and the bolsters, the plates not only support the floor sections 54 but also provide rigid connections between the center and side sills.

The floor section supporting members forming parts of crossbearers include angle bars 57 resting on and rigidly secured to the top flanges of the Z-bars ll of the center sill 1t and in contact with and rigidly secured to the vertical flanges of the angle bars 25 and the inner edges of the top flanges 20 of the major side sills 19. One flange 57a of each angle bar 57 serves as part of a floor section 54 and the other flange 57b is vertical and overlaps and is secured to an upper diaphragm plate 58 having a lateral bottom flange 58a resting upon the top flange of the adjacent Z-bar of the center sill. The edges of the plate 58 are in contact with and secured by welding to the web and top flange oi the adjacent major side sill 19. The supporting member is completed by a diaphragm plate 59 which overlaps the lower edge of the plate 53 and is secured thereto by welding. The plate 59 is also welded along its edges to the webs of the adjacent Z-bar 11 and major side sill 19 and to the top of an I-beam 17. The supporting members at the ends of the middle sections 23 of the major side sills preferably include two angle bars 57 placed with their vertical flanges parallel and the diaphragm plate 58 lying between them. The rigid assembly of one or two pairs of angle bars 57, a pair of upper diaphragm plates 58, a pair of lower diaphragm plates 5?, and an l-beam R7, together with the adjacent parts of the center sill bars 11, acts as a crossbearer extending between the major side sills and supporting the movable column 28 and also acts as a supporting member for a floor section 54. By securing the

diaphragm plates

53, 59 to the center and major side sills an unusually strong construction is provided.

The floor sections 54 are further supported between the bolsters and crossbearers and between adjacent crossbearers by supporting members which comprise angle bars 6t) resting on and secured to the top flanges of the Z-bars 11 and in contact with and secured to the angle bars 25 attached to the top flanges of the adjacent major side sills. The angle bars 60 have lateral flanges serving as parts of respective floor sections and vertical flanges secured by welding to diaphragm plates d1. Each diaphragm plate 61 rests upon the top flange of a Z-bar ll and has a vertical edge secured to the web of the adjacent major side si-ll 19. Each plate 61 is provided with a horizontal flange 61a to give it additional strength. The combination of an angle bar 6%? and a diaphragm plate 61 secured rigidly together and to a Z-bar of the center sill and to the adjacent major side sill not only performs the function of a support for a floor section 54 but also acts as a cross tie.

The ends of the cradle are closed by end walls, each of which includes a plate 62 having a horizontal bottom flange resting on and secured to the topflanges of the Z-bars 11 of the center sill. The upper edge of the plate overlaps and is secured to one flange of an inverted channel member 63, which extends between the vertical flanges of the angle bars 25. A fabricated H-beam 6 5, on the inner face of which is mounted a plank 65, is mounted on top of the channel member and lies be tween the floor sections 54. A pair of angle bars 66 are attached to the channel member and extend down and are secured tothe outer faces of the webs of the Z-bars 11 and to the lower flanges thereof. The wall is further strengthened by angle bars 67 secured to the outer faces of the plates 62 and to the outer faces of the webs of the bars 11.

In the use of the car in transporting coils C, the coils are placed in the cradle with their axes extending lengthwise of the trough and they are held in place by transverse blocking bars which rest upon the top flanges of the angle bars 2 5 and are secured in place by pins passing through the blocking bars and into openings in the flanges. The bars required for the purpose are relatively light in weight and they may be easily placed in position and removed. Heavy coils are preferably placed in the trough over the bolsters and it will be noted that the spac ing of the members supporting the floor sections of the cradle is smaller near the bolsters than in the middle of the car. After the car is loaded, the'coils are protected by a cover of inverted trough form which is placed over them and rests on the top flanges 2th of the major side sills 19. The horizontal flanges of the angle bars 25 act as anchoring means to prevent lateral shifting of the cover and it is secured in place by any suitable means. With the cradle formed as an integral part of the car structure and the coils securely anchored in the cradle, the long travel cushioning mechanism affords good protection to the car and lading. The loading of the coils into the open top cradle and their removal are simple operations which can be easily performed by equipment available for the purpose.
