July 11, 1961 c. GABRIEL CONVERTIBLE CAR FLOOR 2 Sheets-Sheet 2 Filed Sept. 10, 1959 INVENTOR. 67/419155 6459/62 fimwuflw United States Patent 9 Filed Sept. 10, 1959, Ser. No. 839,139 7 Claims. ('Cl. 105-422) of truck or rail shipments. Care must be taken during loading operations to provide safe secure loads which will not shift during movement and will avoid damaging the product. This requirement is particularly troublesome when coil product is shipped since coils require extensive bracing and are subject to severe damage.
The manner of loading and bracing material for shipment is subject to many variations depending on the type of carrierused, the number of units to be shipped per carrier, and size, weight, shape, and the like. Sheet product is generally shipped in multiple sheet lifts, with each lift secured to a pallet in the form of a wooden platform skid. For shipment in gondola cars and tractor trailers, two wooden guide strips are secured to the vehicle floor in laterally spaced and longitudinally extending positions to permit emplacement of the legs of the supporting pallet outside the guide strips. This provision is generally the only requirement for shipping sheets.
Shipment of coils usually requires wooden cradles for supporting the coils and extensive bracing to preventmovement thereof. To simplify loading requirements, gondola cars have been adapted for use exclusively as coil shipping cars. Since the majority of gondolas have been converted for coil shipment, their use for transporting sheet product requires removal of the supporting cradles and braces provided for shipping coils. During peak shipping periods, the coil cars are in constant use, but when lower levels of production and shipping are encountered or when shipment of coils decline, these cars remain idle.
One of the principal objects of this invention, as indicated, is to provide a floor structure with convertible provisions adapting it for handling coils as well as palletized stacks of metal sheets. Other objects and advantages of the invention will become apparent from the followingdescription.
In the drawings there is shown a preferred embodiment of the invention. In this showing:
FIGURE 1 is a fragmentary plan view of a car floor structure constructed in accordance with the principles of this invention showing it conditioned for the transport of metal sheets;
FIGURE 2 is a view similar to FIGURE 1 but showing a portion of the floor structure converted for t; e shipment of coils; I
FIGURE 3 is a sectional view taken along the line III-III of FIGURE 2; and
FIGURE 4 is a sectional view taken along the line IVIV of FIGURE 2.
The drawings show somewhat diagrammatic-ally the body of a carrier vehicle such as, for example, a truck trailer or a railway gondola. As best shown in FIGURE 1, it has a wood floor that includes spaced side portions 1 with a pair of center portions 2 arranged therebetweeu which have abutting engagement along a line 3 corresponding to the longitudinal center line of the carrier.
2,991,734 Patented July 11, 1961 floor. The bars 5 are placed on the floor in pairs arranged:-
parallel to each other and extending in a direction longitudinally of the fioor area in selected positions of lateral adjustment according to the load to he handled. FIG- URE 4 shows a wood pallet 7 that forms a transport support for a stack of metal sheets 8 and the manner inwhich the guide bars 5 are arranged along the inner edges of its supporting legs 9-to position the pallet 8 on the floor and restrain it against lateral move-ment with respect thereto. The anchoring lugs 6 on the guide bars 5 are preferably offset relative to their longitudinal center-line to provide for lateral adjustment of their anchored positions which is eifected by reversing their lengthwise posi-- tions on the car floor.
As shown in FIGURE 3 a trough 10- is arranged be tween the adjacent edges 11 of the side floor portions 1:. The trough extends the length of the car floor and is constructed to provide laterally spaced side surfaces 12 that convergeangularly downwardly from the edges 11- and a horizontal bottom surface 13 that extends betwee the lower ends of the side surfaces 112. Inthis mannerthe trough '10 is adapted to receive a coil: 14 of'metal strip in a position with its axis extending in a lengthwise direction and with its periphery supported on the trough side surfaces 12 which operate to restrain it against rolling movement.
The floor center portions 2 are formed bya pairof removable fillerelements or chooks 15' which are adapted to occupy positions received in and filling the trough 10: asshown in FIGURE 4 or in positions along opposite edges of the trough 10 as shown in FIGURE 3. In thelatter positions, the elements 15 have surfaces 16 that form extensions of the trough side surfaces 12 andactas chocks to hold a coil 14 against rolling movement. The chock filler elements 15 are secured to the floor byhinges 17 (shown diagrammatically) for pivotal movement between the positions shown in FIGURES 3 and 4. The elements as shown in FIGURE 1 are made in relatively short lengths arranged in end to end relation along the length of the car to permit opening of selectedportions of the floor for the reception of coils and to thus, permit handling ofboth coils and palletized stacks of strip. metal sheets in the same car.
When the filler elements 15 are received in the trough 10 as shown in FIGURE 4, the surfaces 16- have supporting engagement on the trough side surfaces 12 and the surfaces 18 thereon are supported on the bottom trough surface 13. In this position, the upper surfaces 19 of the elements 15 cooperate with the surfaces of the side portions 1 to provide a floorarea which is continuousover the width of the car. When pivoted to the coil receiving position shown in FIGURE 3, the surfaces 19 have supporting engagement on the floor area surfaces of the side portions 1.
As best shown in FIGURE 2, the surfaces 18 have openings 20 at spaced intervals along the length thereof for the reception of anchoring pins 21 at opposite ends of brace bars 22. The brace bars 22 are arranged and anchored in positions extending transversely of the trough 10 adjacent the ends of a coil 14 and serve to brace the coil received therein against longitudinal movement in the trough 10.
The outer ends 23 of the filler elements have a curved contour with respect to their hinge connections 17 to permit free pivotal movement to and from a position in the trough as shown in FIGURE 4.
From the foregoing, it will be apparent'that the floor structure of this invention adapts a transport vehicle readily for the handling of coils as well as palletized stacks of metal sheets. Attention is particularly directed to the fact that it is only necessary to pivot the elements through an angle of 180 about the hinge connections 17 to convert the car fioor for the handling of coils. If only one or a few coils are to be shipped, the remainder of the floor area may be used for transporting palletized stacks of metal sheets or other pallet supported loads.
While one embodiment of my invention has been shown and described it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claims.
