' 7 Claims. (Cl. 10S-215) This invention pertains to a novel method for the transportation of freight. A very considerable proportionof the traflic in goods and passengers formerly transported over railways or jointly over railways and highways now passes over highways exclusively, especially Where the passengers or goods are to be transported relatively short or intermediate distances. The gradual taking over by the bus and truck lines of such a consid erable portion of the passenger and freight traiic of the'country has been brought about by numerous wellknown causes which need not be here enumerated. But one-principal advantage which the highway carrier has over the railway carrier consists in his ability to transport goods or passengers from any shipping point in one locality to any ydefinite receiving point in a different locality without trans-shipment of the goods or handling during'transitrin any manner.y n This method of transport whichuis generally designated door-to-door transportnot only saves greatly in time of shipment over that mode'of transportation which involves loading onto and unloading from railway cars at transfer points, but is less expensive to the shipper, and in most cases insures that the goods willA be received in better condition than whenL they pass over the railways. The increasing passengerl andfreight tratlic on the public highways has, however, greatly increased the traffic hazard incident to ordinaryhighway travel, the busses, trucks and trailers now commonly Vused being in many instances of such large size and great weight as to constitute objectional traic hazards as wellas being destructive to the highways.

-Various Ymethods have heretofore been suggested for improving the above methods of transportation, but none ofmthey v methods heretofore advanced has adequately solved the problem. n For example, it has been proposed to ship loaded highway trailer trucks on railway ilat cars, on the theory that a saving in time might thereby be made,j' be cause railways generally form the most direct route between principal points, provide the easiest grades forhtraic, avoid congested cities, and in general constituteinstrumentalities for the safe, fast and economical movement of traiiic of all kinds. It has also been proposed to provide a highway truck with an extra set of wheels,'similar to railway car wheels, with provision for lifting, and lowering one or the other set of wheels, for example, for elevating the highway wheels to allow the othercwheels to rest on the railway tracks so that the vehicle can then be treated as a railway car to be hauled along? the track byY a locomotive'. Further, it has been proposed to provide the vehicle with highway wheels whichcanibe'elevated so as to allow the truck body to bei-.set upon railway trucks such as are commonly used orxsupporting railway cars. However, in all of the previouslyproposed methods the vehicle body with its wheeled support, Vincluding-the highway wheels and associated-parts', is vall transported with the load, addingl ver-yfsiibstantially tov thel` pay'ftonnageand even more vimportantljvlceping -theawheeled support witli'its highway Off Uu wheels out of use during the period while the vehicle body is being transported by rail.

AsY contrasted with prior proposals, an object of the present invention is to make use of a container which may readily be shifted from supports provided with highway wheels to supports provided with railway wheels,

or vice versa, thus avoiding the transportation of ex-` g, cessive weight and making those supports, which are not in use for supporting a particular container, available for moving another container over the highway or railway. To this end in accordance with the present invention, 5V

the body has a kingpin adjacent to each of its respective ends, one ofY said pins being engageable with a suitable socket in a dolly provided with usual highway wheels having rubber tires and the other engaging a socket in a motor propelled tractor, also provided with highway wheels having rubber tires, thus providing a vehicle for use -on the highway, the same kingpins being designed'k for engagement alternatively with sockets in a pair of spaced independent railway dolly trucks having wheels designed to run on a railway track, thus forming a railway vehicle. terchange, and assuming that the body has been in use as part of a highwayvehicle, the body will be lifted from the highwaydolly and tractor (having first been placed adjacent and substantially parallel to the railway track)rand 'will then be moved sidewise until its kingpins are directly above and registered with the sockets in railway trucks,'herein, to avoid confusion in terms, being referred to as bogies properly placed apart on thegrailway track, the body then being lowered to engage its kingpins withy the` sockets of the respective railway The vehicle body is so designed as to be capable of sustaining ther maximum tractive force imposed upon bogies.

it when a plurality'of units (each comprising a body resting upon spaced independent railway dollies) are connected to form a train. been coupled together and a locomotive having been coupled to the forward unit, the train thus formed will tioned to receive it. The landing gear of the Vehicle body is then moved to operative position and the body is then lowered so that its rear kingpin enters the'so'cket of the dolly while the landing gear -supports its forward end. A tractor may then be positioned to receiveV the" forward kingpin of the vehicle body and the landing gear is raised, the body thus again becoming a partpof a highway vehicle capable of travel over highways to its final destination. advantages of the invention will be pointed outyin the following more detailed description and by reference to the accompanying drawings, wherein v Fig. 1 is a diagrammatic elevation illustrating a vehicle c body, in accordance with the present invention, jmountedVVA for movement over the highway by a customary type of power tractor; Y y

Referringi to theldrawings, there isi-shown in Fig. l a vehicle designed for useA on the highway, and which in eX- ternal appearance. generally resembles a conventional trailer truck. ln accordancewith the present invention, inpreparation fori highway travel, the elongate container or body portion 10, which has no wheels of its own, isidetachably mounted atits rearrend upon a road dolly 11, and at.its frontend upon a motor propelled tractor 12, the dollyfandtractor being provided with conventional rubber-tircd wheelslfor use on the highway. As illustrated, the body or container 10 is provided with a retractible landingigear 15.for use insupporting the forward end of the body, at times, when the tractor 12 is disengaged from the. body. To facilitate the detachable connection of the body tothe dolly.11 and theV tractor 12, the body is provided, as iliustratedmore clearly inFigs.` 5 and 8, withkingpins. 13 and 14. near. its rear and forward ends respectively, these. kingpins. being designed to enter appropriate:socketsIprovided in the dolly 11 and the tractor 12; Desirably. some appropriate locking means shouldbe assembled withpeach kingpin 13 and 14 for detachably securing. the vehiclebody to the dolly and tractor.

InFighZ the ,vehiclefof4 Fig..1 is shown asstandinglat a transfer: station .with itslongitudinal axissubstantially parallel., to a standard gaugejrailway track 16. 1t will be: understood that in pulling'into ythis transfer station the driver will endeavor to place the truck body` as nearly parallel with the railroad track as is practicable, and will endeavor to stop the vehicle at a definite position such as might` be indicated for example, by means of a mark or otherfdevice on the parking ramp at which the vehicle comes torest. Thevehiclewill be provided with suitable brake means, and after the vehicle has stopped, the landing gear 15 will be moved downwardly to the position shown in Fig. 3, and the tractor 12 will then be withdrawn from beneath the forward end of the vehicle body 10, leaving the `latter supported on the dolly 11 and the landing gear 15.

With the body 10 in this position, two independent railway bogies or dollies 17 and 18 will be moved to positions such as indicated in Fig. 4, on the railroad track 16 unless said bogies are already standing there with their brakes locked, as the result of a previous operation in which a vehicle body was removed from them and placed on road wheels. These bogies or dollies 17 and 18 which are wholly independent and normally unconnected areprovid'ed with sockets' 13b and 14hdesigned for the reception of the kingpins` 13 and 14 ,carried by the vehicle body. ln preparation for the reception of the container 10, the bogies are sospaced apart that the axes of the sockets 13b and 14h are spaced apart the same distance as the axes of the kingpins 13 and 14 of the body or container 10. The bogies 17 and 18 are provided with anged iron wheels of railway-type resting on the track 16, and are furnished with couplingsi19 and 20 at their remote ends respectively.

Assuming that these bogies are in proper position, the

body 10 is now lifted, together with the dolly 11 byaany suitable lifting means, for example, a suitable wheeled support or transfer dolly which may be placed beneath the container and then elevated so as to lift the container with the dolly 11.

It may be necessary, after having lifted the container body and highway dolly 11, to shift the body or container longitudinally one way or the other a short distance, to bring its kingpins into proper relation to the sockets of the railroad bogies, to com-pensate for any inaccuracy in parking me vehicle. It may also be necessary, while it is so lifted to orient it about a vertical axis to bring its longitudinal axis into true parallelism with the railway track thereby to assure the proper location of the dolly 1i relatively to the railway track to receive another body brought by rail to the terminal. The vehicle body and the dolly 11 are now again lowered until the dolly rests on'the ground; the rear kingpin is disconnected from the dolly 11 and the body is again lifted high enough to clear the dolly 11, and the landing gear 15 isfolded to an inoperative position. This position of the trucltbody 10 with reference to the dolly 11 is illustrated in Fig. 5 (but without any attempt to show the lifting means by which the truck body is thus elevated). The body 10 is now moved horizontally in a direction at right angles to the railway track until its kingpins 13 and 14 are directly above and in registry with the socket 13b and 14b in the bogies 17 and 18. The body or container is lowered and the kingpins enter the respective sockets, the body or container now occupying the position relative to the bogies or dollies 17 and 18 as show in Figs. 6 and 7.

The transverse movement of the container above describedl results in leaving the dolly 11 standing empty at one side of the track. If desired, a tractor may now be connected to this dolly and may carry the latter away to some point of use, but preferably the dolly 11 will be left beside the track in readiness to receive another truck body brought to it on the railway.

A locomotive 21 may now be coupled to the'forward` coupling 20 of the bogie 18, and the railway vehicle comprising the body 1t) and the bogies 17 and 18 may now be hauled by the locomotive to any desired destination,` it being understood that a series of these railway vehicles or units, each comprising a body 10 and bogies 17 and 1 8, may be coupled together one after another to form a train. As above noted, the railway bogies 17 and 18 are independent, and the only connection between them is through the container 10 when the kingpins of the container are seated in thesockets in the railway bogies. If desired,ithe sockets Vof the bogies17 and 18 may beprovided with means cooperative with locking devices associated with the kingpins 13 and 14 for locking the body to the railway bogies.

Assuming that the locomotive has hauled the above railway vehicle constituted by the container 10 and the bogies 17 and 18 to a destined transfer station, where the vehicleand locomotive will be in -the same relation as shown in Fig. 6, and thevbrakes on the bogies 17 and 1S having been set, the locomotive may now be uncoupled from the bogie or dolly 18, and by suitable lifting means, such for example as above referred to, the

body 10 is now elevated from the bogies 17 and 18, and is then moved horizontally in a direction at right angles to the railway track (Fig. 7) until its rear kingpin` 13 is directly above and in registry with the socket in a rubber-tired roaddolly 11lA which, may for` example, have been standingini that positionsince a vehiclebody was` lifted therefrom, as above described. The container 10 is now'lowered until its kingpin` 13 enters the socket in the dolly 11a, thel landing gear 15 having rst been lowered to support the forward end of the vehicle body until a tractor is available to haul it away. When a tractor is available it is engaged with the forward kingu pin of the vehicle body, the landnggear is folded up,Y

avrait ness to be drawn by the tractor 12 (Fig. 9) to the destination of the goods.

1 While the method of procedure according to the present invention has herein been illustrated and described as applied to the shift of a single container from a road dolly and tractor to trailway bogies standing on a railway track so as to form a railroad vehicle and the subsequent retransfer of the body from the railroad bogies to a second dolly and tractor, it is to be understood that the operation may be carried out in either direction, and that in the same station containers may be transferred from wheeled supports designed to travel on the highway to wheeled supports designe-d to travel on the railroad trackwhile containers are taken from wheeled supports `on the railway track and transferred to wheeled supports for use on the highway, or in fact, to the same wheeled highway supports as those from which a body has just been shifted to wheeled railway supports.

No attempt has been made to describe or illustrate in detail many of the adjunctive features which are common to highway and railway vehicles and which are well understood by those skilled in the art, nor has any attempt been made to illustrate in detail the features of an efficient transfer station, the single track 16 and the parking ramp for a single truck being here suggested merely by way of example of a single unit which might be incorporated in such a transfer station. It is to be understood that any and all modifications such as fall within the terms of the appended claims are to be regarded as within the scope of the invention.

I claim:

1. That method of transporting goods which comprises as steps placing the goods in road vehicles, each consisting of an elongate container, unprovided with wheels of its own, which is detachably mounted at its forward and rear ends respectively, upon a tractor and road dolly, each provided with rubber-tired wheels designed for highway use, hauling the vehicles, thus constituted and in each of which the container forms the vehicle body, to a railway terminal where pairs of independent bogies, each bogie having railway wheels, are standing in spaced relation on a railway track, parking each of said road vehicles alongside of the track so that one is Iadjacent to each respective pair of independent, relatively movable railway bogies, removing each container from its respective tractor and road dolly andl detachably securing its opposite ends to the two railway bogies of a corresponding pair, respectively, thereby forming a railway car of which the container alone constitutes the body, assembling several of the railway cars, each thus consisting of a container and a pair of railway bogies, so as to constitute a train by coupling the rear bogie of one railway car to the front bogie of the next car to the rear and hauling the train thus made up, by means of a locomotive, along the railway to another railway siding, assembling road dollies each having rubber-tired highway wheels, in properly spaced relation adjacent to said last-named siding and with one dolly adjacent to the rear portion of each railway vehicle respectively, removing cach container from its respective railway bogies and detachably securing its rear end to the corresponding road dolly while providing a temporary support for the forward end of said container, bringing a tractor, provided with rubbertired highway wheels, into operative relation to the front of each container and connecting the container thereto while removing its temporary support, thus again forming a plurality of highway Vehicles in each of which one such container constitutes the body, and moving the vehicles, so constituted, to the respective destinations for the goods which each vehicle contains.

2. That method of transporting goods according to claim 1, wherein each container is transferred from a parking space adjacent to the railway track by iirst slid- .ing a transfer device beneath the container, lifting the container by means of the transfer device, moving the transfer device with the elevated container supported thereon until the container is directly above the railway track, allowing the containerk to descend thereby to place the container on the railway bogies, and thereafter sliding the transfer device from beneath the container.

3. That method according to claim 2 wherein, while the transfer device is holding the container in elevated position, the transfer device is actuated to orient the container until its front-to-rear axis is exactly parallel to the rails ot' the siding.

4, That method of transporting goods according to claim l, wherein, preparatory to transferring the container to the railway bogies, the tractor is disconnected from and pulled away from the container and the latter is temporarily supported at its forward end by other supporting means, and, while the container is so supported, a transfer device, capable of moving at right angles to the track, is slid beneath the container, lifting the container with its road dolly by means of the transfer device, orienting the elevated container to bring its longitudinal axis exactly parallel to the railway track, lowering the container with its dolly until the wheels of the latter rest on the ground, disconnecting the dolly from the container, removing the temporary support from the front end of the container, elevating the container to clear the dolly and moving the transfer device transversely of the track to position the ends of the container above the respective railway bogies standing on the track. y

5. That method of transporting goods according yto claim 4, wherein, while the container body with said rear dolly is in elevated position, the container is moved in the longitudinal direction thereby to position its opposite ends properly with reference to the corresponding pair of spaced railway bogies.

6. That method of transporting goods from a shipping point to a distant destination partly by highway and partly by railway, and wherein the goods to be shipped are placed in an elongate container designed to constitute the only connection between two independent and otherwise unconnected wheeled supports, and wherein the container is of such construction that it is capable of sustaining the maximum traction force to which it may be subjected when so employed, the container having a single, downwardly directed kingpin adjacent to each end, respectively, said pins being design-ed to enter sockets in the respective wheeled supports, characterized in that for highway travel the wheeled supports are a road dolly, having two sets of highway wheels, and a power-driven tractor also having two sets of highway wheels, respectively, and wherein, for railway travel, the wheeled supports are two railway bogies each having two pairs of flanged wheels designed to roll on railway rails, entering the kingpins of the container into the sockets of the road dolly and tractor repsectively, thereby forming a highway vehicle of which the container constitutes the body, hauling the container, by means of the tractor to a point of railway interchange where a pair of railway bogies are standing on a railway track, relatively moving the bogies until their sockets are spaced apart a distance equal to the distance between the kingpins of the container, drawing up the highway vehicle alongside the railway track so that the kingpins of the container are adjacent to but spaced laterally from the respective bogies, disconnecting the tractor from the container while temporarily supporting the forward end of the latter by other supporting means, sliding a transfer device, capable of moving transversely of the railway track, beneath the container, elevating the container, together with its road dolly, by means of the transfer device, orienting the container while so elevated thereby to bring its longitudinal axis into parallel relation to the railway track, moving the container longitudinally until its kingpins are exactly opposite the sockets of the respective railway bogies, lowering the container until the wheels of its road dolly rest arr/amer onltheground, disconnecting thedolly from the container and causing the temporary supportingrneans `at the front of 'the cc'mt'airierv to become inoperative,Ielevatinggthe contz'riner` suticiently to clear the road dolly, leaving tliedolly in position to receive another container from the railway, moving the transfer device transversely of the railway track to position the kingpins of the container directly above the sockets of the respective railway bogies lowering the container until its kingpins are within the sockets of the bogies, sliding the transfer device out from beneath the container, leaving the container as the sole connection between the railway bogies, thus forming a railway car of which the container constitlutes the body, and moving said railway car along the railroadl to a pointof highway interchange convenient to its ultimate desination.

7. Method according to claim 6, wherein at the point of highway interchange a road dolly provided with highway wheels and having a socket for the reception of a kingpin, is arranged alongside the railway track, stopping theA railway car comprising the container carried by the railway 'oogies so that the rear kingpin of the container is approximately opposite to the socket of the dolly, slacking the coupling between the railway car and the locomotive, or the next adjacent cars if several of said cars have been coupled in series, slidingT a transfer device, capable of moving at right angles to the railway and also longitudinally of the railway track, beneath the container and in the space between the railway bogies, connecting the transfer device to the center of the container, moving the transfer device longitudinally of the Cil railway track thereby moving vthe railway bogies along the-track until the rearkngpin of 'the container is di-A rectly opposite to the socket of the dolly, elevating the container by means of the transfer device to clear the kingpins of the container from the sockets of the railway bogies, moving the transfer device with the elevated container transversely ofthe railway track until the kingpin of the container is above the dolly,` orienting the ele'- vated container until its kingpin is exactly aligned with the socket of the dolly, lowering `the container by means of the transfer device to enter the kingpin of the conrainer in the socket of the dolly, disposing temporary supporting means beneath the forward end of the container, sliding the transfer device from beneath the container, thereafter seating the forward kingpin in the socket of a power-driven highway tractor, making the temporary supporting means ineffective, and by means of the tractor moving the container along the highway to its ultimate destination.
