April 27, 1965 E. H. SHARP MULTI-LEVEL TRANSPORT STRUCTURE 2 Sheets-Sheet 2 Filed Sept. 25, 1961 United States Patent 3,189,233 MUL'll-LEVEL TRANSPGRT STRUCTURE Everett H. Sharp, Lambertville, Mich, assignor to Dana Corporation, Toledo, Ohio, a corporation oi Virginia Filed Sept. 25, 196i, Ser. No. 140,513 5 Claims. (Cl. 105-6655) This invention relates to transport structures in general, and is more specifically directed to a transport structure adapted to transport vehicles by railway cars.

Many prior art structures disclose devices for mounting a plurality of vehicles on a railway car for the convenient and safe transportation thereof. These devices have been limited in the means usable therein by reason of the railroads limitation in the height and width requirements of the combination of the vehicle carrying superstructure and the railway car. However, to operate economically, the railway must position a large number of vehicles simultaneously on a railway car.

To this end numerous prior art devices have incorporated means for accommodating the plurality of vehicles. These prior art devices are highly complex and some of the various vehicle carrying decks of the superstructures incorporate means for longitudinally tilting the decks thereby longitudinally staggering the vehicles. These means are highly complicated, expensive, and'tend to have a very limited operational life.

it is, therefore, an object of this invention to provide a vehicle carrying superstructure for a railway car which will accommodate a large number of vehicles.

It is another object of this invention to provide such a structure havinga plurality of vertically spaced decks which need not be displaced subsequent to the loading of vehicles thereon while still carrying a plurality of vehicles in a staggered relationship.

It is yet another object of this invention to provide a.

vehicle carrying deck arrangement for a railway car whereby a minimurnoverall height will be provided with out increasing the width of the railway car.

7 it is another object of this invention to provide a vehicle carrying superstructure having a plurality of vehicle carrying decks wherein the vehicles on the lower deck are maintained substantially horizontal and the vehicles in the second deck are canted or tilted laterally and straddle the upper portion of thevehicles in the lower deck thereby reducing the overall height requirements for said first and second decks. i

it is yet a further object of this invention to provide a railway car superstructure adapted to carry vehicles which does not require adjustment of the decks subsequent to the vehicle being loaded thereon to displace the vehicles from a horizontal position.

It is a yet further object of this invention to provide such a structure which is simple and durable in construction and can be secured to a standard railway car with very little effort. 7

Other and further objects and advantages of this invention will become apparent upon reading the following detailed description when taken in conjunction with the accompanying drawings wherein:

FIG. 1 is a side elevational view of a railway car embodying this invention;

3,180,283 Patented Apr. 27, 1965 hicle carrying deck and support the first level of vehicles. A second deck is attached to the superstructure and disposed whereby the motor vehicles supported thereon are canted laterally and has means whereby the ground Wheels of the second level of motor vehicles may straddle the uppermost portion of the first level of vehicles thereby FIG. 2 is an enlarged end elevational view of the rail-. way car illustrated in FIG. 1 with vehicles shown disposed thereon.

FIG. 3 is an enlarged plan view of the tie down means used for the lower deck.

. in the embodiment illustrated, a vehicletransporting device is'provided consisting of a vehicle carrying-superstructure suitably mounted on a railway can, The deck of the railway car is adapted to'serve' as the lower vereducing the overall height of the first and second levels. The third or top deck is adapted to carry the top level of motor vehciles in a substantially horizontal position and has means whereby the ground wheels of the top row of vehicles may straddle the uppermost portion of the canted vehicles in the second level. By laterally canting the second level of vehicles, and adapting the second and third decks whereby the vehicles contained thereon will straddle the uppermost portion of the vehicles in the next lower level, a great savings in vertical displacement of the superstructure and vehicles carried thereby is obtained without increasing the width requirements of the superstructure beyond the maximum allowable.

Referring now to the drawings and more particularlyto FIGS. 1 and 2, a railway car shown generally at it] is provided with the usual plurality of ground wheels 12 and a longitudinally extending main frame portion 14. The upper surface of the main frame 14 forms a horizontal lower deck 16, which extends longitudinally for substantially the whole length of the railway car it More particularly, the main frame 34 is provided with integral vertically inclined, longitudinally extending side members 18 terminated at their uppermost portion with attaching means in the form of a horizontal flange 29.

The lower deck 16 provides the means for supporting the first level of vehicles one of which is shown at 24, and

has fixedly attached thereto a pair of laterally spaced longitudinally extending wheel abutment means 26 positioned to engage the outer lateral side of a plurality of ground wheels 23 of the vehicle 24 so that when the vehicle is moved onto the deck 16; it is properly positioned.-

ments disposed so as to act in shear in response to longitudinal shock loads, is fixedly attached as by bolts 38 to an upright portion of flange 32 and to an L-shaped mounting bracket 4%. A laterally extending cross bar 42 is attached to the base of bracket lti by a plurality of bolts, one of which is shown at 44, and has fixedly attached to the ends thereof longitudinally extending notched Z-shaped members 46. The members .45 are disposed in spaced parallel relationship and have a portion thereof slidingly received in longitudinally extending inverted L-shaped members- '58. The L-shaped members 48 are fixedly at tached to the lower deck 16. it is readily apparent that the Z-shaped members 4'6 may slide longitudinally inthe L-shaped members id and in so doing are resiliently connected to the deck 15 by means of the tie-down device 3%). A plurality of chains 59 are securedly engagedat one end to a finger-portion 52 formed by the spaced notches .in member id and at the other end are secured to the vehicle 24 in a-suitable manner. 'By means of the above described connection between the vehicles 24 and the" lower deck '16, the vehicles 24 are supported in a resilient v manner and protected against impact shock loads.

' Arvehicle carrying superstructure shown generally at" 54+ is preferably composed ofa plurality of aligneclpad jacent sections shown generally. at 56, 58, il and 62,

. a which sections are resiliently attached to the main frame 14. Since the plurality of sections are substantially identical, only one section 56 will be hereinafter described. The section 56 consists of three pairs of longitudinally and laterally spaced channel shaped side posts 64 disposed in opposed relationship. The bottom portion of each side post 64 is fixedly attached to a substantially horizontal bracket member or attaching means 66. The bracket member is disposed in parallel relationship with the flange attaching means on the main frame 14 and interconnected therewith by a suitable resilient means shown generally at 68. The juxtaposed side posts of adjacent sections preferably have a common bracket member 70 which bracket is supplied with a pair of resilient means 68; however, all of the side posts 64 may have individual brackets 66 and be individually attached to the frame 14.

The resilient means 68 preferably take the form of a resilient cushion which has a plurality of elastomeric elements 69 interconnected and faced by plates 71. The upper and lower portions of the resilient means 68 are suitably attached to the

brackets

20 and 66 so as to be deformed in shear to dampen impact loads.

' The attaching means 20 and 66 are further provided with means for limiting the lateral movement of the superstructure 54 relative to the main frame M- 50 that the superstructure cannot move sufiiciently laterally to engage the lower level of vehicle 24. More particularly the bracket 66 has a downwardly extending lip portion 74 and the flange 29 has an upwardly extending lip portion 76. The lip portions are arranged in cooperating relationship whereby they will engage each other after limited lateral movement between the superstructure 54 and the frame 14.

A second deck 78, which supports the second level of vehicles one of which is shown at 86, extends longitudinally for the length of each section of the superstructure 54. The second deck is fixedly attached at its lateral extremities to channel-shaped mounting brackets 82 which in turn are fixedly attached to the side posts 64. Triangular shaped brackets 83 securedly interconnect the brackets 82 and the posts 64 to provide additional support therebetween. As apparent in FIG. 2, the second deck 78 is provided with means whereby the vehicles 80 positioned thereon are canted from the horizontal position relative to the vehicles 24 supported by the lower deck 16. More particularly a lateral portion 84 of the deck 78 is deformed so that it extends below the remaining portion 86 and closer to the first deck 16. The remaining portions 86 is substantially horizontal and of sufiicient width and height to accommodate the roof of the vehicle 24 positioned therebelow. With the second deck 78 disposed in this manner, the vehicle 80 supported thereon has the ground wheels 88 on the right side thereof supported by the portion 84 and disposed at a level below the roof of the vehicle 24, and the ground wheels 96 on the left side thereof supported by the remaining portion 86 so that the wheels 90 are above the roof of the vehicle 24, thus, the vehicles 80 are laterally canted and the ground wheels thereof straddle a portion of the roof of the vehicle 24. It is readily apparent that by so straddling the vehicle 24, the overall vertical displacement between the vehicles contained on the

decks

78 and 16 is less than if the vehicles 80 in the second deck were in a substantially horizontal position with the ground wheels 88 on the same level as the ground wheels 90 and both the

wheels

88 and 90 above the roof of the vehicle 24-.

A pair of laterally spaced longitudinaly extending wheel abutment means 26 are fixedly attached to the deck 78 and engage the outer lateral sides of the

ground wheels

88 and 90 of the vehicle 80 to properly position the wheels when the vehicle is moved onto the deck 78 and to further prevent lateral displacement of the vehicle. A plurality of longitudinally and laterally spaced tie-down means 92 are carried by the deck 78 and selected ones have an end of one of the chains50 securedly attached thereto. The other ends of the chains 50 are securedly attached to the vehicle 89. Since the superstructure 54 is resiliently mounted on the railway car 10, the vehicles are sufiiciently protected from impact loads if they are merely securedly attached to the superstructure and move unitarily therewith. Therefore, neither the tie-down means 92 nor the chains 50 securing the vehicle 89 thereto need include load damping means.

If it is to desired, a third level of vehicles, one of which is shown at 94, may be positioned on the railway car It). For this purpose a longitudinally extending third deck 96, having its lateral extremities disposed in a substantially horizontal plane, is secured at its lateral extremities to channel shaped mounting brackets 82. The brackets are in turn fixedly attached to the side posts 64. Triangular shaped brackets 33 securedly interconnect the brackets 32 and the posts 6-.- to provide additional support therebetween. As apparent in FIG. 2, an intermediate portion 98 of the deck 96 is displaced upwardly so that the upper portion of the lateral portions 1% of the deck 96 may be disposed below the roof of the vehicles 80 on the second level. In this manner the wheels 182 of the vehicles 94 may straddle a portion of the roof of the vehicle 80.

A pair of laterally spaced longitudinally extending wheel abutment means 26 are fixedly attached to the deck 96 and engage the outer lateral sides of ground wheels 102 of the vehicle 94 to properly laterally position the vehicles 94 when they are moved onto the deck 95. A plurality of longitudinally and laterally spaced tie-down means )2 are carried by the deck 96 and selected ones have an end of one of the chains 58 securedly attached thereto. The other ends of chains 50 are securedly attached to the vehicles 94. Therefore, the vehicles 94 are protected from impact loads in the same manner as previously described for the vehicles 80.

To load the transport structure, a loading means (not shown) having levels which are at the same vertical height as the

decks

16, 78, and 96 is used. The vehicles are moved (as by driving) from the load means onto the decks and down the length of the superstructure 54. If necessary, suitable bridge means (not shown) may be positioned between the adjoining

sections

56, 58, 60 and 62 of the superstructure 54 so that the vehicles may be driven the length thereof.

From the foregoing it is apparent that a vehicle carrying superstructure for a railway car has been described that will accommodate a large number of vehicles with minimum height and width requirements, that carries a plurality of vehicles in a staggered relationship yet need not have the decks thereof displaced subsequent to the loading of vehicles thereon, wherein the overall stacked height of the vehicles is at a minimum, wherein the reduced stacked height is accomplished by straddling the upper portion of the vehicles in each level with the wheels of the vehicles in the next above level, and wherein some of the levels of vehicles are canted laterally to reduce the stacked height.
