18 Claims. (Cl. 10S- 367) The present invention relates to railway cars and more particularly to an improved car of `the type adapted for transporting coils of steel and similar freight and in which covers are provided for protecting the freight from the weather, and which may be opened for loading and unloading.A t

It is an object of the present invention to provide an improved railway car of the above mentioned type which is simple in design, durable of construction, reliable and eicient in operation and economical to manufacture.

n More specifically, it is an object of the present invention toprovide an improved railway car of the above mentioned type employing cover halves mounted for movement between closed positions in which the freight is fully covered and open positions in which the car may be loaded and unloaded, and to provide improved means for mounting the cover halves for movement between these positions and to provide improved means for effecting such movement. A Another object of the present invention is to provide a railroad car of the above mentioned type in which the means for -mounting the cover halves and moving them between their closed and open positions includes spring means loaded in both the closed and open positions and effective to assist in movement of the cover halves from both positions. l

It is a further object of the present invention to provide a railway car of the above mentioned type including cross members for bracing the coiled steel or other freight received in the car and in which the cover halves co-operate with the attachment means for securing the ends of the Icross members in place so that this attachment means cannot be detached when the cover halves are in closed position.

It is also an object of the invention to provide improved means for mounting the cover halves so thatthe car body may deflect as when it is loaded or unloaded, or as an incident to normal movement over the rails or switching, without deilecting or distorting the cover halves.

While only two specific embodiments of the invention are illustrated herein, and such embodiments are especially designed for use in the transporting of coiled steel, it will be appreciated that the improvements of the present invention may be embodied in railway cars designed for the shipment of other freight.

YIn the preferred embodiment illustrated, the railway car 10 comprises tnicks 12 at the opposite ends thereof upon which the car body 14 maybe supported in conventional manner. In the preferredembodiment illustrated the railway car body 14 includes a pair of heavy side sill members in the form of spaced parallel I-

beams

16 and 18 disposed in spaced parallel relation at opposite sides of the body 14 and comprising a rigid part thereof. Between the I-beams is mounted a bed generally indicated at 20 which, in the preferred embodiment illustrated is adapted to support coils of sheet steel disposed with their axes extending horizontally and along the length of the car, such a coil being illustrated in broken lines in FIG- URE 2 at 22. Cover halves 24 and 26 are mounted on the

beams

16 and 18 for pivotal movement between the closed positions illustrated in the drawings and open positions in which the coils of steel or other freight may be loaded onto and unloaded` from thebed 20. In the preferred embodiment illustrated each cover half moves through an angle of about degrees in moving between its closed and open positions. The cover halves 24 and 26 are fabricated of sheet metal or other suitable material and includes arcuately shaped wall portions 28 and 30 cooperating to deline a generally semi-cylindrical cover portion, the height of which above the bed 20 is increased by virtue of the straight wall sections 32 and 34 of the cover halves. At their opposite ends the cover halves are provided with walls 36 and 38 which, in the preferred embodiment illustrated, include pivotally mountedend

wall portions

40 and 42 which swing relative to their

respective end walls

37 and 38 above the

pivots

44 and 46 when the cover halves are moved to their open position to increase the opening at the end walls of the cover halves in the manner illustrated and described in greater detail in Patent No. 3,009,426, granted November 2l, 1961, to the assignee of the present application, and on application of S. M. Nampa.

As is readily seen in FIGURE l, the cover halves 24 and 26 extend substantially through the entire length of the car 10. and in the preferred embodiment illustrated are formed as five separate sections 52, 54, 56 and 58,

@the adjacent ones of which are provided With co-operat- 3 ported on the

beams

16 and 18 through a plurality of hinge arms 48 which are secured to the lower part of the straight sections 32 and 34 by brackets 50. The hinge arms 48 extend generally arcuately downwardly and are Vwelded to a tubular operating shaft 64 which is supported on its associated I-

beam

16 or 18 through brackets 66 spaced along and welded to a channel 68 which is secured to the outer surface of the associated I-

beam

16 or 18 by bolts 70. The brackets 66 are provided with rollers 72 rotatably supporting the tubular operating shaft 64 which is held in place in the bra-ckets 66 against the roller 72 by straps 74 secured to the brackets 66 by bolts 76. It will be noted that the hinge arms y48 are spaced along the cover halves as illustrated in FIGURE 1 so that the force applied through these arms in opening and closing the cover halves is spread throughout the length of each cover half. Also, it will be noted that the cover sections are provided with'external reinforcing channels 53 disposed at, and to which, the hinge arms 48 are connected.

The force for moving each of the cover halves between its open and closed positions is applied to itsassociated tubular operating shaft 64 substantially at its midpoint through an inner shaft 78, the inner end of which carries a drive fitting 80 telescopically received in the end of the inner shaft 78 and welded thereto as indicated at 82 (see FIGURE 6). This drive fitting 80 closely fits the inner bore of the tubular operating shaft 64 and is connected thereto for rotation therewith by the drive pin 84 extending through the drive tting 80 and the tubular shaft 64 and headed over at its opposite ends as illustrated at 86. The inner tubular shaft 78 extends outwardly of the left-hand end of the tubular operating shaft 64 as illustrated in FIGURE 1 and carries at its outer end a drive crank 88. The drive crank 88 for each cover half is provided at its outer end with a nut 90 and each of these nuts is threadedly received on a screw shaft 92, the outer end of which has a nut portion 94 adapted to be engaged by a power tool, such as an air wrench, for driving the screw shaft 92. The screw shafts 92 have their inner ends connected as best illustrated in FIG- URES 3 and 4 to the outer ends of tubular shafts 96, the inner ends of which are connected by the universal coupling illustrated in FIGURE 4. This coupling includes a connecting shaft 98 journalled in bearing blocks 100 and the axial movement of which is limited by collars 102 welded to the shaft 98. Outwardly of the bearing blocks 100 in whichV it is journalled, the connecting shaft 98 has a pin and slot connection indicated at 104 to each of the tubular shafts 96. It will now be appreciated that the universal connection afforded by the coupling illustrated in FIGURE 4 permits the raising and lowering of the outer ends of the screw shafts 92 which is required because of the pivotal movement of the crank arms 88 during the rotation of the screw shafts 92 to effect movement of the cover halves between their open and closed positions.

It is also contemplated that, if desired, rather than using a power tool to drive one of the screw shafts 92 through engagement with a nut portion 94 thereof, the motive power may be supplied by a suitable motor such as an air motor permanently installed on the ycar and operatively connected, for example, to the shaft 98 for effecting desired rotation of the latter.

To facilitate movement of the cover halves between their open and closed positions, a plurality ofleaf spring elements 106 are cantilever mounted on the

beams

16 and 18 as best illustrated in FIGURE 5 by brackets 108 and the free upper ends of the springs 106 are received between abutments 110 and 112 fixed on the tubular operating shaft 64 and defining a slot 114 therebetween. The abutments 110 and 112 are so positioned that with the cover in the closed position, as illustrated in the drawings, each spring 106 is deflected in one direction from its unloaded condition by the abutment 112 `and when the cover is in the open position the spring elements 106 are deflected in the opposite direction from their unloaded condition by the abutments 110. It will thus be appreicated that the spring elements 106 assist in moving the cover elements both from the closed position and the open position and also that the springs oppose the force of gravity as the cover halves move to either the closed or the open position loading the springs.

The cover halves 24 and 26 are held in the closed position by a latch 116 pivotally mounted on the cover half 26 which engages behind an upstanding keeper ange 118 on the cover half 24. The cover halves are guided into proper closed position by conically shaped pins 120 carried by the cover half 24 and which are received in apertured brackets 122 carried by the cover half 26.

Referring to FIGURE 2, it will be seen that the car is provided with cross members generally indicated at 124 which may be of the construction illustrated and described in greater detail in copending application Serial No. 405,937, filed October 23, 1964, assigned to the assignee of the present application and filed in the names of Harvey W. Chapman and Herbert E. Rolfe, Jr. At their opposite ends the c ross members 124 are connected to the I-

beams

16 and 18 by latch pins 126 extending through apertures provided in the'end portions of the cross member 124 which are aligned with apertures spaced along the upper inner anges 128 of the I-

beams

16 and 18. The cover halves 24 and 26 are provided with angles 130 secured at the inner side thereof adjacent the lower portion of the straight sections 32 and 34 as illustratd in FIGURE 2, which angles are disposed, when the cover sections are in their closed positions, in the path of movement of the latch pins 126 as they are withdrawn from the latched position shown to unlatched positions. It will thus be appreciated that when the cover sections are in the closed positions illustrated, the latch pins 126 cannot be withdrawn and the cross member cannot be detached from the

beams

16 and 18.

Referring to FIGURE 8, it will be seen that the figure illustrates diagrammatically and in somewhat exaggerated manner the upward chamber which the car frame structure has when the car is in the unloaded condition4 The heavy side sill member 16 of the car frame is there shown as being upwardly bowed at its center. By Way of illustration, when the car is loaded the car frame may deflect at its center as much as one and one-half inches.

It is a feature of the present invention that this deflection may occur without corresponding deflection of the cover and the corresponding distortion thereof which may cause misalignment and interfere with the proper operation of the cover. This is accomplished in the construction illustrated inFIGURES l, 2, 3 and 8 as follows.

The channels 68 upon which the cover halves 24 and 26 are mounted through the arms 48 and the hinge tube 64 are supported on the

side sill members

16 and 18 so as to permit vertical movement of the center portions of the

side sill members

16 and 18 relative to the central portions of the channel 68 during the above mentioned deflection of these sill [members as a part of the deflection of the car from when it is loaded. The channels 68 are also supported so as to permit the longitudinal movement of their end portions relative to the side sill ymembers which occurs during such deflection of the car body frame. Referring to FIGURE 8, it will be seen that the channel 68 is provided, in spaced relation to the center thereof, with spaced pairs of vertically elongated apertures through which the above mentioned bolts 70 extend to secure the center portion of the channel 68 to the center portion of the side sill lmembers 16 and 18. Approximately halfway between the apertures 140 and the adjacent ends of the channel 68 are additional pairs of vertically elongated apertures 142 which may be slightly wider horizontally than the apertures 140. Adjacent each end of the channel 68 are additional pairs of horizontally elongated apertures 144. Similar bolts 70 are used through all of the apertures 140 and 142 and 144 and on said bolts and disposed between each channel 68 and the side sill member to which it is connected are anti-friction washers 146` (see FIG- URE 2). By way of illustration, one make of such washers is sold under the trademark Oilite. The bolts 70y at each of the apertures 140, 142 and 144 prevent movement of the channel 68 transversely of the car body While permitting movement in the vertical plane of the web of the channel 68.

It will now be appreciated that during the deection of the

side sill members

16 and 18 relative to the channel 68, the center portionof the side sill member adjacent the apertures 140 will move vertically but will have very little horizontal movement whereas at.the end portions of the channel 68 adjacent the apertures 144 the movement of the side sill members relative to the channel 68 will be horizontal. In the intermediate portions of the side sill members adjacent the apertures 142 there will be some vertical movement during such deflection and some horizontal movement of the side sill member relative to the channel 68. This latter horizontal movement is accommodated by proportioning the slots 142 so that the horizontall dimension thereof is larger than the diameter of the shanks of ythe bolts 70 to permit such-movement. Similarly, the apertures 140 are slightly larger horizontally than the diameter of the Shanks of the -bolts 70-to provide for any slight movement of the portions of the side sill members adjacent these apertures in a horizontal direction relative to the channel 68 which may result from the short spacing of these apertures 140 from the center of the channel 68. The structure of the assembly consisting of the cover halves 24 and 26, the structure supporting them on the channels 68, and the channels 68 has suiiicient rigidity so that no vertical support for this assembly is required intermediate the end apertures 164 at which the opposite end portions of the channel 68 are supported on the

side sill members

16 and 18 by the bolts 70.

. It willthus be seen from a consideration of the foregoing description of the structure illustrated in FIGURES 1 to 8, inclusive, that the applicants have providedv a construction in which the car frame may deflect in a vertical 'direction as, for example, when the car is loaded or unsame result is obtained in the construction there illustrated.

Except for the differences noted hereinafter, the construction of the modification illustrated in FIGURES 9 to 15, inclusive, may be Vin accordance with the construction illustrated in FIGURES 1 to 8, inclusive.

In the construction of FIGURES 9 to 15, inclusive, the side sill members 150` may be of the same construction as the side sill members 16 and 18-but it will be ynoted that in this modiedfconstruction there are no channels 68. Each-hinge tube 152 is .supportedtat its opposite ends directly onthe side sill member 150 through selfaligning bearings 154 as best illustrated in FIGURE 10. As there illustrated, each hinge tube 152 carries a shaft 156 mountedin each end thereof and extending through and supported in a self-aligning bearing 154 which is mounted on the sill member 150 by a short channel section 158 to which it is secured by bolts 160 and which is in turn welded ,to the side sill member 150 as indicated at 162. At each end of the hinge tube 152 the shaft 156 carries a stop plate 164 welded thereto and disposed adjacent the -channel 158 to4 limit longitudinal movement of the hinge tube 152. Intermediate the ends of the hinge tube 152 the cover halves, one of which is indicated at 166, are supported thereon at a plurality of points spaced therealong by hinge arms 168. Also, at a plurality of points spaced along each hinge tube 152 it isheld against horizontal movement relative to the side sill member and transversely of the carvbody by support assemblies generally indicated at 170.

. Each of these support assemblies comprises a plate 172 welded to the side sill member and having the center portion thereof disposedlin spaced parallel relation to the side sill member as illustrated in FIGURE 13. The plate 172 is provided with a plurality of keyhole slots 174, the upper portion of which is adapte-d to receive the heads of bolts 176, the shanks of which extend. through a mounting plate 178 and receive nuts 180.. On the .bolts 176 and intermediate the mounting plate 176 and the plate 172 are anti-friction washers 182 such, for example, as the above-mentioned Oilite washers. The keyhole slots 174 in the plates 172 have a vertically extending portion adapted to receive the shankof the bolts 176 and are of a length adapted to accommodate the relative movement between the side sill member 150 and the hinge tube 152 during deflection of the frame of the car upon the loading thereof. In the embodiment illustrated in FIGURE 9, one of the support assemblies is located at the center of the car and two support assemblies 170 are disposed in equal spaced relation at opposite sides of the center one. Because of the spacing of these last mentioned support assemblies from the center of the car, it will be appreciated thatthere will be some small horizontal movement of the portion of the side sill member to which these support assemblies are secured longitudinally relative to the adjacent portion of the hinge tube 152 during deflection of the car frame and accordingly, the width of the lower portion of the keyhole slot 174 in which the shank of the -bolt 176 moves during such deflection is larger than the diameter of the shank of the boltsuticiently to permit such movement. The mounting plate 178 carries a pair of spaced parallel vertically disposed support flanges which are apertured to receive the hinge tube 152.

From the foregoing it will be appreciated that while the support assemblies 170 permit any required -movement of the mouting plate 178 relative to the plate 172 during deliection of the car frame, the mounting assemblies 170 serve to support the hinge tube against movement horizontally tranversely of the car body toward or away from the side sill member 150. A

lIt will be noted that FIGURE 12 shows the position of the bolts 176-at the bottom of the keyhole slots 174 which is the position occupied when the caris empty and the car frame has the upward camber illustrated in FIGURE 8. The proportions of the keyhole slots 174 are such that after insertion `of the heads of the bolts 176 through the upper porti-on of these slots during assembly of the support assemblies 170, the shanks ofthe bolts 176 remain within the lower portions of the slots, both while the car is empty and during all deflections of the car frame relative to the hinge tube 152. Here, again, in the embodiment illustrated in FIGURES 9 through 15, inclusive, the structure of the cover halves 166 land their connections to the hinge tube 152 are such as to provide a selfsupporting structure which does not require vertical su-pport other than at the self aligning bearings 154 through which it receives it-s sole vertical support.

For operating the cover halves 166 between the open and closed positions, the shafts 156 at the lett-hand end of the hinge tube 152, as viewed in FIGURE 9, and which are shown in FIGURE l0, extend beyond the selfaligning bearing 154 and carry an actuating arm 186 (see FIGURE 15). As `in the above described embodiment illustrated in FIGURES 1 to 8, inclusive, these arms 186 are operated by reversely threaded

shafts

188 and 190 universally connected as indicated at 192 and provided with end portions 194 adapted for engagement by a suitably driven power tool indicated `at 196 and leaf spring elements similar to the leaf spring elements 106 of the embodiment illustrated in FIGURES 1 to 8, inclusive, and which function similarly to facilitate move-` ment of the cover halves between their open and closed positions.

While only two specific embodiments of the present invention have been illustrated and described in detail herein, it will be readily appreciated by those skilled in the art that numerous modifications and changes may 'be made without departing from the spirit of the present invention.
