(til. 105-455) The present invention relates to railway cars, especially to railway cars adapted to receive thereon removable freight containers, freight trucks, trailers, or the like.
At the present time, there is a lot of commercial interest in and use of various types of special railway cars that can be used for hauling large freight containers thereon, or which may receive truck trailers thereon for hauling the truck trailers or freight containers specified distances and permitting their removal as units for delivery, or further shipping action, as desired. Thus there has been quite a bit of activity in the designing and production of railway cars adapted to carry truck trailers thereon so that the truck tractor can directly pull a trailer, for example, to a given railway car and deposit it thereon by some type of endwise loading application. There have been efforts made to facilitate the loading of these trailers onto railway cars and the attaching of such trailers to the railway car for safety hauling them by freight train to their destination.
In all events, insofar as I am aware, nearly all of the constructions proposed heretofore and in use at this time involve relatively tedious, costly loading and unloading operations, and they require either very extensive railroad yard areas for loading the freight trailers onto the railway cars, or else the systems are only efficient with two or three railway cars in a row and do not work well with longer freight car assemblies.
It is a general object of the present invention to provide a novel and improved freight car characterized by the provision of a rotatable load carrying body therein whereby side loading of the cars with freight trailers or freight carrying compartments is facilitated.
Another object of the invention is to provide improved means for raising, lowering and turning a freight carrying platform provided on a railway car.
Another object of the invention is to provide a novel railway car adapted to carry freight trailers thereon at a minimum overall height for the railroad car with the freight trailer secured in a fixed position on the railway car for transit.
Further objects of the invention are to provide novel hydraulic lift means in a railway car of the type described wherein a load support platform can be readily raised and lowered in the freight railway car and be carried in a recessed center portion of the car for freight transit action; to provide novel roller means for furnishing easy turning and support action between a movable load platform in the railway car and support means provided therefor by which the load platform can be rotated about a center support trunnion therefor; to provide novel, effective guide means in the side sills of the car so that special lift members can be raised and lowered in a vertical plane only for controlling the position of the load or support platform provided therein; to provide special anchor members on portions of the railway car for engaging a freight trailer to position it fixedly on the railway car for transit.
The foregoing and other objects and advantages of the present invention will be made more apparent as the specification proceeds.

The present invention, generally speaking, relates to a railway car wherein the car has a reduced height center section extending the full width of the car, and it has elevated end portions connected in a conventional manner with railway car trucks, and where the railway car comprises a frame, a load carrying platform supported by the frame, trunnion means positioning the load carrying platform on the frame for arcuate and limited vertical movement on the reduced height portion of the car, support members extend longitudinally of the car adjacent each side thereof and below the load platform, means operatively securing the support members to the frame for vertical movement of the support members with relation to the frame, which support members engage the load platform on vertical upward movement by the last-named means, and roller means are operatively connected between the load platform and the support members to facilitate arcuate movement of the load platform when carried by the support members.
Having particular reference now to the details of the structure shown in the accompanying drawings, a railway car is indicated as a whole by the numeral 1. This railway car embodies the principles of the present invention and has included therein a set of conventional railway trucks 2, 2 at each end of the car 1, which trucks 2 are secured by conventional means to the load carrying, or frame portion of the railway car 1. The railway car 1 has ends or load carrying decks 3 provided at the ends of the railway car and which ends 3, 3 are of a fixed vertical height, or position. The railway car 1 also has a vertically movable center portion provided therein carried by a vertically recessed portion of the railway car frame whereby a reduced height load support platform can be provided intermediate the ends 3, 3 of the railway car.
The railway car 1 has suitable frame means that normally extend the length thereof, and with the frame means generally comprising a center sill 4 made from a pair of channels 5, 5 placed in spaced, parallel, back-to-back relation, and a pair of side sills 6, 6 each of which is made from a pair of channels 7 and 8 placed in spaced, parallel relation adjacent the lateral margins of the railway car 1. These center sills 4 and side silis 6, 6 can be made from integral eyebeams, channel members, or equivalents, that smears would have portions cut therefrom on the lower surfaces thereof at the ends of the railway car to contour the sills over the trucks 2, 2 and would have portions cut or otherwise removed therefromat the tops thereof at the center portion of the railway car to provide for a reduced height center portion therein. Or, these center and side sills can be made from members of different contours at the ends and center portion of the railway car, as desired. in all events, the channels 5, '7 and 3 preferably have top and bottom flanges provided thereon either integral therewith, or welded or riveted thereto, to aid in recnforcing such channels for load carrying action, and some or portions of the flanges may be formed from original parts of the beams cut therefrom and resecured thereto to different portions thereof. Or the side sills and/ or center sills may be made from a plurality of vertically superimposed channels the adjacent flanges of which are welded or riveted together.
A load platform is provided at the center of the railway car 1 and extends t e width thereof between the ends 3, 3 of the car. This load platform includes a plurality of transversely extending channels or beams lull that may have members, such as a cover plate, or deck, 11 secured to the upper surface thereof. Longitudinally extending parallel tie bars, or beams 12 extend the length of the load platform and are secured to the unit of the deck ll and cross beams to to complete the load carrying portion of the load platform 9 it is an important feature of the present invention that the load platform d is pivotally or rotatably carried on the railway car 1 and to this end, trunnion means, such as a trunnion sleeve 13, is secured to and extends between the channels 5, at the center of the recessed center portion of the railway car It, usually at the longitudinal center thereof. This trunnion sleeve 13 extends above the center sill 4, and is adapted to receive a suitable trunnion 14 therein. This trunnion 1 has a trunnion plate or bracket 15 secured thereto and extending longitudinally of the railway car 1 therefrom for engagement with a pair of the cross beams iii, in forming a part of the load platform 9 to transmit load from the load platform 9 onto the trunnion 14 for support action in the trunnion sleeve 13. The trunnion sleeve 13 and trunnion 14- are operatively connected to provide and permit pivotal and vertical movement of the trunnion lain the receiving and positioning sleeve 13. The trunnion I14 slidably engages the trunnion sleeve 13 for vertical movement with relation thereto. Pivotal movement of the trunnion lid is produced by external forces applied to the trunnion 14 through the load platform 9. The trunnion 14 preferably has some type of conventional lubricating means, such as fabric wick means in having conventional lubricant material saturating the wick means 1%, carried by a portion of the trunnion 14 so that lubricant can seep through holes 17 provided in the trunnion fit to lubricate the connection between the adjacent surfaces of the trunnion sleeve 13 and the trunnion lid.
t is a further feature of the invention that the trunnion 14 and trunnion plate 15 are secured to the load platform 9 by means that permit some relative tipping movement therebetween. Hence cap members or securing brackets lids, 4, are suitably secured to the cross beams it? adjacent the trunnion 14 to loosely bridge over the ends 15:) of the trunnion plate 15 but to permit limited tilting of the load platform in a transverse or longitudinal direction and slight arcuate freedom of the trunnion, if desired. The ends 155 of t :e trunnion plate are of slight convex curvature, top and bottom, to in permitting limited relative movement of the load platform and the trunnion with minimum clearance therebetween. The trunnion sleeve 13 has a flange 13:: thereon to aid in securing the trunnion sleeve in position while the trunnion 1d also has a top flange 14a thereon to fac litate its engagement with the trunnion plate 315.
Any desired cross frame means may be used in building the frame of the railway car and connect the center sill 4 to the side sills 6, 6.
it should be noted that in FIG. 3, the load platform 9 and means associated therewith is shown in a retracted or lowered vertical position, whereas in MG. 1, such load platform is shown in its elevated position at which time the deck 11 thereon is parallel with the surfaces of the ends 3, 3 to facilitate movement of a truck or other loading vehicle over the railway car 1 for depositing a tractor trailer, or other freight receptacle, onto the load platform 9 FIG. 3 of the drawings best shows how the cross beams it? of the load platform 9, when the load platform is in its load carrying position for transit action, are received on and supported by the channels 5, '7 and 8, so that fixed load support or carrying action is provided for this load platform 9. It is an important feature of the present invention that other load carrying or lifting means are provided in the railway car 1 for facilitating rotational or arcuate movement of the load platform 9 when desired for aiding in applying freight to, or removing it from the load platform A Hence a pair of elongate support members l5, 18 are provided in the railway car 1 and they extend the length of the reduced height center portion of the railway car and protrude beyond the ends of this load platform Q for operative association with the side sills 6, 6 of the car for vertical movement with relation to the frame or side sills of the railway car ll. The support members 18 may comprise an I-beam with the top flange thereon removed, a pair of back-to-back right angles suitably secured together, or an equivalent member having a base flange l9 and a vertically upwardly extending web 20 thereon. These support members 18 are received in the open centers or" the side sills 6, 6 and are retained centrally therein by suitable means, such as a plurality of rollers 21, 21, journalled on brackets 22 secured to longitudinally spaced portions of the web 20 so that the rollers 2.1, 21 are adapted to engage the inner surfaces of the side sills t5, 6 and be guided vertically thereof. The webs preferably have load carrying ends 2?: usually vertically upwardly offset in the railway car i with relation to the remainder of the webs 29, 2t and the reduced height center portion of the railway car. These ends 23 are shown in FIG. 5 and have a suitable base plate 24 secured thereto and extending laterally therefrom. Such offset ends 23 and base plate 24 are provided on the support members it; to adapt them to be engaged by ertical lift cylinders 25, or similar means, received within the open centers of the side sills d, 6 adjacent the trucks 2, 2. The lift cylinders 25 may be secured in position by means of support plates 26 riveted, bolted, or otherwise secured to and extending between the lower margins of the side sills 6, 6 whereby load on the support members 18 is transferred to and from the side sills through these base plates 26 and the lift cylinders 25.
The lift cylinders 25 control the position of a support plunger or piston 27 that extends from the cylinder and engages the base plat $24, with the position of such piston 23 being controlled by the supply of hydraulic fluid to the lift cylinder 2:; through fluid supply conduits 2S and These conduits 28 and 29 connect to a conventional source of hydraulic pressure fluid (not shown) whereby hydraulic fluid will be forced into or be permitted to exhaust from four lift cylinders provided in the railway car 1. That is, a pair of lift cylinders 25, 25 will engage each of the support members id provided in the railway car adjacent the ends thereof so that a uniform lifting or lowering action will be provided for the load platform 9 and any load or freight carried theeby.
FIGS. 1 and 3 show that the upper members of the rollers 21, carried by the web 20, extend above such web and are adapted to engage different cross beams 16 of the load platform as the support members l3, l8 are raised up into engagement with the load platform 9 to lift it above the side sills and center sills in the railway car.
The rollers will then facilitate turning the load platform on its supports.
Any conventional type of coupler means (not shown) can be secured to the. railway car 1 for conventional coupling action to engage it to adjacent railway cars.
A modified type of load support, platform and associated means is shownin FIGURES 7 and 8 of the drawings. In this instance, aload-platfo-rm 9a is shown and it has ,a pair of longitudinally extending beams 12a provided on its upper surface. This modification of the railway car and load support platform is particularly adapted to facilitate the movement of some type of a freight carrying body or article longitudinally along the load platform 9a. A dolly assembly 40 is provided and it usually has a member, such as a load engaging hook 41, pivotally secured thereto and extending therefrom for engaging a member, such as a freight receptacle or body 42. The dolly assembly 40 includes a plurality of pulleys or sheaves 43, 43 that are suitably journalled on a center bracket 44 of the dolly assembly. These sheaves 43, 43 are adapted to engage the laterally inner flanges of the beams 12a. The bracket or frame 44 has a control cable 45 secured thereto, extending around a pulley 46 journalled at one end of the load support platform 9a, and returning to a control winch 47 secured to the load platform 9a at the end thereof remote from the pulley 46. This winch 47 can be of conventional design and can be controlled by mechanical or power means, as desired (not shown). In all events, by the use of the winch 47, one can move the freight container or compartment 42 onto or from the load platform 9, and this load platform ha can rotate about the journal or trunnion means provided therefor as in the other embodiment of the invention for loading and unloading action. The control cable 45 may extend around another pulley (not shown) adjacentthe winch .47 or else extend directly to a load to aid in moving load from the load platform 90.
With reference to the modification of the structure shown in FIGS. 9, and 11, in this instance a railway car lb is shown that has a depressed height center portion 50 provided therein as in the other embodiments of the invention. A load support platform 91; is pivotally positioned in this lowered height center portion 50, by trunnion means as previously described. Usually the center load platform 9 is of the length of a freight container, or trailer received thereon. However, when desired, this freight container, such as a conventional trailer 51, may be longer than the load platform 9b, as shown. Thus in order to support this trailer 51 for safe transit on the railway car lib, a plurality of support members are provided at the opposite elevated end portions of the railway car. A pair of parallel eyebeams 52 and 53 usually are secured to the deck of the railway car lb for longitudinally strengthening the floor or deck thereon, and support members of conventional or desired design are provided for engaging means, such as the fifth wheel and/or king pin 54, of the trailer 51. In this embodiment of the invention, a pair of beams 55 and 56 are shown removably secured, as by bolts, to the beams '52 and S3 to extend upwardly therefrom, and other support beams, members, or sections 57 and '58, usually of shorter length than the other beams 52 and 53 and 55 and 56, are removably secured to the beams 55 and 56, respectively. The actual load carrying member in this instance comprises a support or fifth wheel or king pin engaging plate 59 that is suitably secured to the beams 57 and 55 to form a support unit therewith. The plate 59 has an aperture 61 therein to engage with the king pin 54 and associated plate of the trailer 51. A similar removable support structure we usually is provided at the opposite end of the railway car 1 and it is adapted to engage an end portion of this trailer when the load support platform 9b is lowered down into its recessed position in the railway car. Until load is 6 transferred to these support plates 59 at the ends of the car, the load will be carried by the wheels 61?. on the trailer and the conventional carrier assembly 63 provided adjacent the forward end of the trailer.
,As another feature ofthis embodiment of the invention, preferably the load support platform 9b has a plurality of rollers64, FIG. 11, secured thereto with their longitudinally extending axes parallel to the longitudinal axis of the railway car. These support rollers or casters 64 are suitably journalled on bracket means or similar members 65 carried by the reenforcing beams 66 forming a part of the load platform 9b. These rollers 64 on opposite sides of the reenforcing beams 66 are offset from each other laterally to provide roller support means continually engaging the side or center sills of the railway car when the load platform 91; is being turned.
In any of the embodiments of the invention, preferably some type of mechanical means are provided for turning or moving the load support platform through arcs for loading and unloading purposes. Thus in FIG. 2 of the drawings, typical control apparatus is shown. This apparatus comprises a hydraulically operated cylinder that has a control piston or rod 71 extending therefrom. The cylinder '70 is secured pivotally at one end thereof through universal joint means, as by abracket '72, to and extends laterally from a side sill 6 of the railway car. The piston rod 71 is likewise pivotally secured, as by a bracket 73, to a portion of the frame of the load support platform, such as a cross beam 19. Conventional pressure supply conduits and control means (not shown) connect to this cylinder '70 for reciprocating a piston therein in either direction for positively moving the load platform to swing it to 'a side loading-position, or to bring it back into alignment with the railway car, as desired. This arcuate movement of the load platform usually is provided for an arcuate length of approximately 45, but further pivotal action can be provided, as desired.
It should be realized that the railway fiat cars of the invention have ready adaptability for loading truck trailers thereon, either endwise or sidewise from loading ramps or platforms, as desired. At the same, time, the structure of the invention, particularly that shown in FIGS. 7 and 8, is adaptable on the same type of a flat car for carrying some type of a detachable van body or freight container so as to remove it from its normal frame and pull it over onto the railway car and support means provided thereon.
As indicated, any suitable types of reenf-orcing means, including metal plates or wood beams or planks, may be used in making the load support decks and ends of the car. Conventional means connect the trucks to the car frame which itself is reenforced as outlined herein and shown in the drawings.
In view of the foregoing, it is contended that a novel and improved type of a freight car has been provided which car has a minimum overall height and is adapted to carry relatively high vertical loads, such as c0nventional freight trailers thereon. The novel railway car has effective and improved load movement means so that a recessed center load platform in the railway car can be elevated a controllable height to the height of the ends of the railway car for facilitating loading and unloading actions, when desired. This action also permits seating of freight means, such as a trailer, onto suitable support members provided on the elevated ends of the railway car. Obviously these load support members, including the support plates 5's of FIGS. 9 through 11 can be removed from the end portions of the rail- Way car when loading or unloading a freight trailer onto or from the car by endwise loading action. It will be seen that the load support platforms are carried on frame means of the railway car for transit action, but that the lift and support members come into removable engagement therewith for raising the load support platform and facilitating loading action by use of the roller means and arcuate movement of the load platform, as hereinafter described.
It will be noted that the load support platform may be wider than the support frame of the railway car as shown in FIG. 3.
FIG. 8 brings out that a trunnion end 115 is secured to the load platform 9:; by an end cap 115d for limited rocking action therebetween.
Thus it is believed that the objects of the invention have been achieved.
While several complete embodiments of the invention have been disclosed herein, it will be appreciated that modification of these particular embodiments of the invention may be resorted to without departing from the scope of the invention as defined in the appended claims.
