2. Description of the Prior Art The invention is an improvement on my earlier invention US. Pat. No. 3,370,551 the broad concept being to provide a railway vehicle and a road running carrier adapted to be straddle mounted crosswise on the railway vehicle with the direction of travel of the carrier being perpendicular to the direction of travel of the railway vehicle. In certain applications of the road-rail apparatus as disclosed in US. Pat. No.

3,370,551 certain undesirable features are noted particularly with regard to the front and rear road wheels of the carrier overhanging oppositely and intersecting existing railroad lateral clearance lines or wayside structure when the carrier was transportably supported astraddle the railway vehicle. Also, the long wheelbase spacing of the road vehicle of US. Pat. No. 3,370,551 generally restricted its use to vehicle combinations requiring steerable wheels, and the broad wheelbase spacing and vertical wheel movement was not applicable in tandem wheel arrangements.

SUMMARY OF THE INVENTION The instant invention obviates the objectional features noted in the road-rail apparatus described in US. Pat. No. 3,370,551, substantially by providing road vehicle means of tandem wheel configuration having wheels movable upwardly converging downwardly diverging; the wheel movement may be embodied in vehicle combinations of typical tandem wheelbase configuration and without requiring steerable road wheels. The wheels of the roadway vehicle are arranged upwardly convergingly in a contracted wheelbase configuration: (a) when the road vehicle is being rail transported thereby firmly mounting the roadway vehicle on the railway vehicle and affording railroad wayside clearance, and (b) when the road vehicle is in road-running fonn, thereby affording typical tandem wheelbase configuration and ready skewing movement of the wheels on a road surface in road travel.

The converging diverging wheel movement of the road vehicle also provides several ancillary advantages when the vehicle is in road-running form: (a) the wheel movement permits selective adjustment of the load-bed height to correspond with the height of a loading dock or platform, (b) a road vehicle for hauling particulate or bulk material may be fitted with dropbottom gates for dumping a load while the load bed is raised, (c) the folding wheel movement of the road vehicle permits tilting load-bed action without pivotally mounting the load bed, and (d) the roadway vehicle may be fitted to convey and position containers or the like.

The roadrail apparatus is directed toward application in a wide range of transportation activity. It is considered to be useful in general railroad-highway traffic movements, in transporting and positioning containers, in handling water and air freight shipments, in off-highway transporting including earthmoving, agricultural and mining operations, in construction work, transporting heavy equipment, and for use in prefabricated house conveyance and installation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1, 2 and 5 illustrate a somewhat simplified embodiment of the present invention including a railway car 21 and roadway vehicle means 22 including a wheeled carrier assembly 23. Railway car 21 includes a long frame 25, preferably skeleton type in construction, and forward and rearward rail car trucks 27 supporting opposite end portions of frame 25. Frame 25 preferably includes a center sill 29, cross members 31 and forward and rearward railway coupling members 33 arranged on opposite end portions of frame 25. Rail car trucks 27 each include wheel and axle assemblies 35 journaled in truck bearings 37. Flanged wheels 39 runningly engage paired rails 41 of the railroad track.

The base or frame structure 42 of carrier assembly 23 preferably is of openwork construction and includes a transversely arranged medial section 43 and paired inner and outer frame rails 45, 47 rigidly secured to and projecting horizontally from opposite fore and aft sides of medial section 43. Front and rear wheel members 49, preferably dual-arranged wheel members, are pivotally supported on front and rear wheel suspension arms 51 supported on front and rear pivot shafts 53. Bearings 55 subjacently fixed on the opposite end portions respectively of outer frame rails 47 pivotally support front and rear pivot shafts 53 in parallel arrangement and at respectively the forward and rearward areas of the wheeled carrier frame structure. The proximal end of each wheel suspension arm 51 is fixed respectively on opposite end portions of pivot shafts 53. Outwardly extending stub axles 57 are fixedly secured respectively on the distal end portions of wheel support arms 51 and journal respectively front and rear wheel members 49.

Road vehicle means 22 preferably includes reach means in the form of a tongue 59 supported on and extending forwardly horizontally from base structure 42 of carrier assembly 23. Hitch half means 61 secured on the distal end portion of tongue 59 is adapted to coactingly engage hitch half means 63 of a tractor vehicle 65. Tongue 59 is generally hairpin shaped and is adjustably supported from base structure 42 for translational horizontal adjustable movement relative to the carrier assembly base structure. Inner pair of frame rails 45 preferably are tubular and telescopically receive leg portions 67 of tongue 59. Tubular frame rails 45 define channel means for guidingly supporting tongue 59 between a projected disposition whereupon the tongue projects forwardly cantilever fashion from the forward extremity of the base structure (see FIG. 1) and a retracted disposition whereupon the tongue is substantially fully received in frame rails 45 (see FIG. 2).

A removable horizontal lock pin 69 is fitted in aligned apertures in the forward terminal portions of inner frame rails 45 and provides means for locking tongue 59in an extended or a retracted disposition. Beveled surfaces 71 on the forward terminal portions respectively of outer frame rails 47 permit horizontal manipulation of lock pin 69 when withdrawing or inserting the pin in paired inner frame rails 45. Lock pin 69 is adapted to be inserted in apertures provided in tongue leg portion 67 when the tongue is in a projected cantilever disposition (see FIG. 1). When tongue 59 is in a retracted disposition, lock pin 69 bridgingly spans frame rails 45 and abuttingly engages the bight portion of the tongue thereby preventing its forward displacement (see FIG. 2). The horizontally rigid tongue structure extending forwardly from carrier assembly base structure 42 provides rigid reach means providing leverage means for turning the carrier left or right during road travel and when it is being trailingly conveyed by a towing vehicle.

The load-bearing means of roadway vehicle means 23 may be of any fonn suitable for the particular material or load structure handled and may optionally be of flat-bed type for handling solid or vehicular loads; a load containing type having a load container or load shell and binding means removably binding the load shell on the base structure of the wheeled carrier; or a load holding type having load holding van structure permanently secured on the base structure of the carrier assembly: By way of example, roadway vehicle means 22 is illustrated and described as being fitted with a load holding van-type body 73 (the lower portion only of the body being shown in FIG. 1).

The means for actuating wheel suspension arms 51 preferably includes forward and rearward piston-cylinder assemblies or rams 75 and selectively controllable hydraulic power means 77 supported on tractor 65. Conduit means 79 connect hydraulic power means 77 with forward and rearward hydraulic rams 75. Each hydraulic ram 75 is pivotally anchored at its base end by a pin 81 and is pivotally secured at its plunger end by a pin 83 fitted in a lever projection 85 fixed on and projecting upwardly from a respective pivot shaft 53. Actuating control lever 87 on tractor mounted hydraulic power means 77 causes converging or diverging movement of wheel members 49.

For the purpose of clarity in description, FIG. 1 illustrates road vehicle means 22 somewhat ambiguously in both a road running dispodtion and in a rail transported disposition. That feature of the invention whereby front and rear wheel members 49 are arranged in like configuration both for road travel and rail travel is illustrated in FIG. 1. It will of course be understood that tongue 59 is arranged in a retracted disposition as illustrated in FIG. 2 when vehicle 22 is supported on railway car 21 in rail travel.

The procedure for loading roadway vehicle 22 on railway car frame 25 may include the following actions: Road vehicle 22 is trailingly conveyed on road surface S by tractor 65 transversely across and to a centered position over the railroad track. While keeping hydraulic conduit means 79 connected, vehicle 22 is unhitched from tractor 65 and by manipulation of lock pin 69, tongue 59 is moved to a retracted disposition. Control lever 87 of tractor mounted hydraulic power means 77 is manipulated to cause downward diverging movement of wheel members 49 and raising of carrier assembly base structure 42. Railway car 21 is then moved along track rails 41, underneath the carrier assembly base structure and between front and rear wheel members 49. Hydraulic control lever 87 is again manipulated to cause wheel members 49 to move upwardly convergingly and adjacent opposite sides of rail car center sill 29. The hydraulic conduit means 79 extending between vehicle 22 and tractor 65 may then be disconnected, completing the loading procedure.

Vertical and horizontal positioning rollers 89, 91 preferably are joumaled respectively on vehicle 22and railway car 21. Four vertical positioning rollers 89, arranged in generally rectangular configuration, preferably are joumaled on the underside of carrier assembly base structure 42 and respectively dependingly on opposite end portions or paired outer frame rails 47. Confrontingly opening C-shaped brackets 93 (two brackets only shown in FIG. 1) journal vertical positioning rollers 89 in confrontingly arranged pairs of rollers. The vertical positioning rollers are adapted to engage converging side surfaces 95 (see FIG. 5) on the leading end of rail car frame 25 as the rail car is moved beneath the wheel carrier base structure and serve to longitudinally center road vehicle 22 over the rail car as the rail car is moved underneath carrier assembly base structure 42 and between the front and rear wheel members 49.

Horizontal positioning rollers 91 each are arranged in a longitudinally extending row of rollers arranged on opposite sides of rail car frame 25. Rollers 91 are longitudinally arranged and freely joumaled on shafts 97 secured respectively on the opposite distal end portions of crossmembers 31. During the vertical movement of carrier assembly base structure 42, during loading and unloading of vehicle 22, horizontal rollers 91 on railway car 21 may engage vertical positioning rollers 89 of vehicle 22 and provide antifriction means for centering the road vehicle over the rail car. Generally cylindrical shock absorber means or air spring members 99 preferably are fitted respectively on the proximal portions of front and rear wheel suspension arms 51 for providing spring means for the road vehicle during road travel. When wheel members 49 are moved upwardly convergingly, spring members 99 are moved upwardly against the underside of outer frame rails 47 and provide cushioning means between wheel members 49 and base structure 42.

Crawler type tractor 65' and a heavy duty trailer type roadway vehicle having front and rear wheel gangs 49' and a vehicle useful for transportably supporting heavy loads on soft terrain. Although not specifically illustrated, the roadway vehicle 22 includes wheeled carrier structure 23' and means for converging diverging movement of front and rear wheel gangs 49'.

FIG. 1 1 illustrates another embodiment of the invention including a roadway vehicle 22" having selectively operative means adapted for pivotally or rigidly supporting a tongue 59" from the base structure of a carrier assembly 23". Road vehicle 22" is fitted with load holding structure in the form of an open topped hopper 73" having selectively operative drop bottom doors 74". Vehicle 22" is useful for hauling and spreading particulate or dry bulk material; the vehicle may optionally be fitted with dry bulk spreading mechanism or means for spreading or dispensing chemical fertilizer, seeds, granular or particulate materials.

Tongue 59" is arrangeable in three positions, namely, a free pivoting position pivotable on a horizontal axis (as illustrated in FIG. 11); a rigid position (not shown) wherein the tongue projects cantilever fashion from the base structure of carrier assembly 23"; or a fully retracted disposition (not shown) wherein the tongue is retracted within the longitudinal extension of the carrier assembly base structure: Lock pin 69" may be inserted through aperture 70" for arranging tongue 59" in a rigid cantilever disposition or the pin may be arranged as illustrated in FIG. 11 for free pivotal movement of the tongue. Wheel members 49" may be convergingly or divergingly moved during forward travel of vehicle 22" for dumping a bulk material load or for maneuvering the vehicle in field ser- A vice. The embodiments of the invention illustrated in FIGS. 1, 2, 9 and 1 1 depict single tandem full trailer type roadway vehicle means adapted for transporting short length loads or loads of a length which may be contained within or between the lateral clearance lines or stationary wayside structure along a railroad track.

FIGS. 3, 4, 7, and 14 illustrate a semitrailer type roadway vehicle 101 adapted to be utilized with a motor transport tractor 103. Semitrailer vehicle 101 includes a wheeled carrier assembly 105 including base structure 107 having a transversely extending medial section 109 and oppositely projecting paired inner and outer rails 111, 113. Front and rear wheel members 1 are journaled on distal end portions respectively of wheel suspension arms 117 which are respectively supported on front and rear pivot shafts l 19 supported in turn in pivot shaft bearings 121 arranged respectively on opposite end portions of outer frame rails 113. Front and rear axle shafts 123 extend respectively between the distal end portions of front and rear wheel suspension arms 117 and journal respectively front and rear wheel members 115.

The load-bearing means of road vehicle 101 may include removable load shell or container box means or be of any configuration suitable for holding or containing the particular material handled. The load-bearing means exemplified, is in the form of van-type body 125 as illustrated in FIGS. 3, 4, 7, 10 and 14 (only the lower portion of van body 125 being shown in FIG. 3). A king pin hitch half 127 dependingly fixed on the forward underportion of van body 125 is adapted to be coactingly coupled with fifth wheel hitch half 129 of tractor 103. Van body 125, in addition to providing load-bearing means for the material load transported, also provides fore and aft extending reach structure for turning carrier assembly 105 toward the left or right as semitrailer vehicle 101 is trailingly conveyed along a road surface.

Road vehicle means 101 includes vertical thrust pivot means 131 operatively arranged between base structure 107 of carrier assembly 105 and load-bearing van body 125. Thrust pivot means 131 provides means for contradirectional horizontally arced displacement of carrier assembly 105 and van body reach structure 125. A short heavy pivot pin 133 firmly secured respectively in carrier assembly base structure medial section 109 and in the rearward center substructure portion of van body 125 pivotally secures carrier assembly 105 and body 125 against relative radial displacement at the pivot pin. Annular lower and upper thrust plates 135, 137 fixedly secured respectively and on carrier assembly 105 and the rearward substructure portion of van body 125 provide antifriction turntablelike support means for the rearward portion of van body 125 on carrier assembly 105.

Hand lever operative dog means 139 (FIGS. 3 and 7) preferably is mounted on the rearward underside of van body 125 and includes a dog 141 having a shank portion 143 mounted horizontally in bearings 145 fixed dependingly on the substructure of load-bearing body 125. Horizontal movement of dog member 141 into and out of engagement with a notch 147 in lower thrust plate 135 respectively locks or releases carrier assembly 105 and body 125 and constrains or permits relative pivotal displacement of the carrier assembly and van body. A helical compression spring 149 fitted on shank 143 and tensioned between a shoulder 151 on the shank and the forward one of bearings 145 yieldably urges dog member 14] toward lower thrust plate 135 and toward a clogged engagement with notch 147. A horizontal hand lever 153 pivotally fulcrumed at pin 155 to the underside of body 125 and pinned at 157 to dog member shank 143 provides hand operative means for retracting dog 141 from notch 147. A catch 159 dependingly fixed on the underside of body 125 provides means for engaging the distal portion of lever 153 and for holding dog member 141 in a disengaged configuration.

Forwardly and rearwardly arranged pairs of horizontal oppoaitely projecting ram members 161 fitted on carrier assembly base structure 107 actuate respectively front and rear wheel members 115 through wheel suspension arms 117. Forward and rearward pairs of ram members 161 provide respectively simultaneously operative ram means for lifting and lowering the rearward end portion of semitrailer van body 125. Selectively controllable fluid power means 163 connected to ram members 161 through conduit means 165 preferably provides means for energizing the ram members and for converging diverging movement of wheel members 1 15. Selectively manipulating control lever 167 of fluid power means 163 controls the converging diverging movement of wheel members and respectively the lifting and lowering of semitrailer vehicle 101.

The means for loading and unloading vehicle 101 on rail car 21 preferably includes landing gear means 169 arranged on the forward underside of van body for raising and supporting the forward end portion of the van body. Landing gear means 169 includes left and right landing gear assemblies 171 having respectively wheels 173. Telescopically fitted standards 175, 177 operatively interconnected by shaft means and driven by power means 181 extend and retract respectively for raising or lowering van body 125. Power means 181 may be hydraulically or pneumatically energized or may include hand crank means 183 for lifting or lowering the van body. Landing gear assemblies 171 are retractable rearwardly by strut members 185 and in retracted dispositions are received respectively in downwardly opening enclosures 187.

The tractor vehicle of the tractor-semitrailer combination preferably includes power operative means for raising and lowering the fifth wheel hitch half of the tractor. FIG. 14 illustrates a tractor-semitrailer combination including a trucktractor vehicle 103 having a power operative fifth wheel hitch half 129. Selectively operative power means 130' connected to hitch half 129' through link arms 132' provide means for raising or lowering hitch half 129 respectively for raising or lowering the forward end of semitrailer van body 125.

Considering that a tractor-semitrailer combination includes semitrailer road vehicle means 101 and tractor vehicle 103', the following procedure may be carried out in loading vehicle 101 on railway car 21: Tractor-semitrailer combination 101, 103' is moved transversely across the railroad track and to a position whereat front and rear wheel members 115 are arranged symmetrically laterally of the rail track. The front and rear wheel members 115 of carrier assembly 105 are simultaneously moved divergingly outwardly and downwardly thereby raising carrier assembly base structure 107 and spreading the front and rear wheels as shown in FIGS. 3 and 4. Fifth wheel hitch half 129' of tractor vehicle 103' preferably is simultaneously actuated with the diverging actuation of wheel members 1 15 for simultaneously raising the forward and rearward portions of van body 125 and for raising the van body in a level disposition; power means 130 of tractor vehicle 103' preferably is simultaneously operative with the diverging movement of the carrier wheels and the van body is raised and held in an elevated disposition (see broken line showing of the van body in FIG. 14). Rail car 21 is then moved along the rail track and underneath the base structure of carrier assembly 105; the railway car is moved between front and rear wheel members 115 of the carrier assembly and to a position whereat carrier assembly 105 is between forward and rearward rail car trucks 27. Front and rear carrier assembly wheel members 115 are convergingly moved inwardly and upwardly relative to base structure 107 thereby causing the somewhat sequential actions, of (a) lowering base structure 107 to rest on rail car frame 25; (b) raising front and rear carrier assembly wheel members 115 from the road surface; and (c) moving front and rear wheel members inwardly convergingly against opposite sides of rail car center sill 29. Vehicle 101 is now elevatingly arranged with its forward end supported on tractor vehicle fifth wheel hitch half 129' and its rearward end supported on rail car 21 with wheel members 115 arranged astraddle rail car frame 25. Van body reach structure 125 may then be moved in a horizontal arc about pivot pin 133 to a corresponding longitudinally aligned disposition over rail car frame 25 (see FIGS. 10, 18 and 19). Fifth wheel hitch half 129' of truck-tractor 103' may be lowered thereby lowering the forward end of van body 125. Bolster structure 189 (see FIG. 18) may be arranged between rail car frame 25 and the forward end of van body 125 for supporting the forward end of vehicle 101 during rail travel.

A forklifi truck type yard vehicle 191 (see FIG. 19) having horizontal fork structure 193 may be utilized in horizontally moving the forward end portion of semitrailer vehicle 101 in an arc in loading and unloading the vehicle on the railway car. A seat 195 fitted on the distal end of horizontally pivoted and vertically liftable fork structure 193 is adapted to liftably engage the forward underside of van body structure 125 of vehicle 101 and swing the forward end of the body structure in a 90 arc about thrust pivot pin 133. Yard vehicle 191 is operative for loading or unloading semitrailer vehicle 101 without the assistance oftruck-tractor vehicle means 103 or 103.

. Each railway car 21 preferably is long enough to transportably accommodate two semitrailer vehicles 101 (see FIG. A plurality of vehicles 101 may be spotted in intermittently spaced pairs of vehicles along a railroad track by use of respective truck-tractor vehicles 103, 103'. A plurality of pairs of vehicles 101 may be spotted with each pair of vehicles being arranged for loading on a respective railroad car; each vehicle 101 is stationarily supported on its landing gear means 169 and wheeled can'ier assembly 105, and with its van body supported in an elevated disposition. After moving a train of railway cars 21 underneath assemblies 105 of the plurality of pairs of vehicle 101 and centering each car 21 in relation to a respective pair of vehicles 101, yard vehicle 191 may be utilized in horizontally swinging van body structure 125 of each vehicle 101 onto frame means of railway car means 21; a single yard vehicle 191 may be utilized for loading or unloading a plurality of pairs of spotted vehicles 101 on or off a train of railway cars 21.

Two opposingly arranged pairs of vertical positioning rollers 197 arranged each pair on a forward and rearward substructure portion of each carrier assembly base structure 107 are adapted to runningly engage horizontal positioning rollers 91 on rail car 21 as the rail car is moved underneath each carrier assembly base structure 107; opposingly operative pairs of rollers 197 provides means for longitudinally centering carrier assemblies 105 over railway car frame 25 in response to movement of rail car 21 along the railroad track thereby longitudinally shifting semitrailer vehicles 101 each to correct positions perpendicular to a respective rail car. (See FIG. 10). Carrier assembly 105 of each vehicle 101 preferably includes spring members 199 mounted respectively on the distal end portions of wheel suspension arms 117 for cushioning the weight of vehicle 101 in road travel.

FIGS. 16, 18 and 19 illustrate a double tandem full trailer type carrier vehicle 201 including forward and rearward carrier assemblies 203, 205 having respectively base structures 207, 209; load-bearing means in the form of van body 211; and forward and rearward thrust pivot means 213, 215 arranged respectively between van body 211 and forward and rearward carrier assembly base structures 207, 209. A tongue 217 is supported at its proximal end on a horizontal pivot pin 219 supported on forward assembly base structure 207 (see FIG. 16). Hitch half means 221 supported on the distal end of tongue 217 is adapted to be coupled with coacting hitch half means on a towing vehicle for trailingly conveying vehicle 201 in road travel. Dog means 223 operatively arranged between rearward carrier assembly base structure 209 and the rearward portion of body structure 211 is adapted to be selectively manipulated for releasably locking the contradirectional rotational movement of carrier assembly 205 and body 211. Dog means 223 is adapted to be arranged in a locked disposition when vehicle 201 is operative in road travel and is adapted to be arranged in it released disposition when the vehicle is being loaded or unloaded on a railway car or is being transportably supported on the railway car.

Double tandem trailer vehicle 201 may be transportably supported on a single rail car 21 or may be supported on two rail cars 21 as shown in FIGS. 18 and 19. When supported on two rail cars 21, thrust pivot axis means 253, 215 provide pivotal support means for body 211 particularly operative when the two rail cars are in angular relationship and traveling along a curved railroad track. A rail yard tractor vehicle 229 (FIG. 19) may be utilized in loading double tandem vehicle 201 on railway cars 21 and in pivotally manipulating vehicle 201 from a perpendicular relationship with the railroad track (broken line showing in FIG. 19) to a loaded disposition on the railway cars (full line showing in FIG. 19).

In contrast to the loading procedure of single tandem semitrailer vehicle 101, double tandem vehicle 201 is horizontally manipulated by tractor vehicle 229 to a corresponding longitudinally aligned arrangement over the railroad track before railway car means 21 is moved under the base structures respectively of carrier assemblies 203, 205. After railway car means 21 is moved between front and rear wheel members 225, 227 and positioned under the base structures of the forward and rearward carrier assemblies, wheel members 225,

227 are convergingly contracted thereby lowering van body 211 and contracting wheel members 225, 227 from the road surface. Tongue 217 may be pivotally moved upwardly against the side of van body 211 to a stored arrangement and carrier vehicle 201 be disposed in rail travel configuration.

FIG. 15 illustrates a double tandem trailer type arrangement 201' including forward and rearward wheeled carrier assembles 203, 205' having respectively base structures 207', 209'; forward and rearward load-bearing structures 211, 211; and forward and rearward thrust pivot axis means 213', 215 pivotally interconnecting respectively forward and rearward base structures 207', 209' and load-bearing structures 211, 21 1.
