H. IDOINE FRETGHT CAR FLOOR Filed July 1'7 kph 29? 1935@ IN V EN TOR.
Patented Sept. 29, 1936 FREIGHT CAR FLOOR Harry Idoine, Canton, Ohio, assigner of one-half to Lewis A. Hanlin, Canton, Ohio Application July 17, 1933, Serial No. 680,818
9 Claims. (Cl. 105-422) My invention relates to the construction of floors for freight cars, and consists of an improved combination of metal and wood.
The object of the improvement is to provide a floor for freight cars formed of metal and having a plurality of closely spaced transverse channels or grooves throughout its length, in which grooves are located transversely disposed Wooden members, thus providing the strength and durability of a metal floor with means for nailing or otherwise anchoring cargoes thereto.
A further object is to provide such a :door construction in which the metal floor members are connected to the center and side sills, the holsters and crossbearers, whereby a very rigid and sub1 stantial underframe for the car body is profrn duced.
Another object of the invention is to provide a metal floor member having its side edge portions turned downward and then outward and terminating in downturned flanges arranged to be bolted or riveted to the fianges of similar floor members, forming channels or sunken ledges between adjacent metal floor members adapted to receive and retain wooden :door members.
A still further object is to increase the depth of?l the downturned fiange on one side of each metal iioor member and to provide a horizontal flange at the lower edge thereof adapted to be connected at its ends to the center and side sills of the car, this construction being especially desirable where heavy loads are to be carried, such as in gondola cars.
In the accompanying drawing which illustrates my invention,
Figure 1 is a longitudinal section of a box car floor, taken midway of the center sills and sides of the car; Figure 2, a transverse section with the wood plank omitted, showing my improved floor and its method of attachment to the center sills and sides of car; Figure 3 is a perspective view of the metal member; Figure 4 is a transverse section showing my improved noo-ring as applied to a gondola car; Figure 5 is a longitudinal section showing only two of the metal members and one wooden member as applied to a gondola car.
Referring by numerals to the accompanying drawing, l indicates the floor surface of the metal member, which is substantially in the same plane as the floor surface of the wooden member.- At 2 is the wooden member which is bolted to the metal member through its horizontal flange 4. At 3, 4, and 5 are the pressed flanges forming the ledge upon-which rests the wooden member.
The diaphragms of the body bolster and crossbearer are shown at li and 'l respectively, to the upper flanges of which are attached my metal floor member, thus forming a tie plate to connect bolster and crossbearer diaphragms, which are placed on each side of the center sill i3.
The end floor member can be either of metal or wood, if of metal l prefer to ,attach same to the end sheet t by the flange 9, although it is not necessary that flange 9 be turned up as shown, for in some cases it would be preferable that this flange be turned down.
The side sheet and side sills of the box car are indicated at it and il respectively to which my metal floor member is attached by its flanges d and it. The center sill construction of the car is shown at lil and it, on the upper surface of which the lower surface of flange is attached. lt is evident that by connecting the two sides of the car and also the center sills with my metal floor member as indicated a very rigid and substantial underframe for the car body is obtained.
The metal members are secured to each other by such riveted or bolted means as shown at l5.
The vfloor surface of the metal member can be reinforced so that heavy loads being dropped on them will not seriously bend down this surface. I prefer to stiffen same by the pressed ribs indicated by it, although this can be accomplished by such means as an angle secured to the bottom surface of the metal floor member, the pressed rib will be a less costly fabricating operation.
To permit the metal floor member to be securely connected to the upper surface of the center and side sills at i9 and 20 respectively the bottom vertical ange 5 of the metal floor member is cut away as shown at il and it.
Due to the heavier loads carried in gondola cars than box cars, it is necessary to increase the cross sectional area of the metal member and this is preferably done by deepening the bottom vertical flange 5 shown in Figures 4 and 5, and forming a horizontal flange 2l on its bottom edge, this increased area being secured to the center sills i3 and side sheets Ill by suitable connections as shown at 22 and 23. To secure the metal member to the side sheets of the car the ends of the metal member are flanged upward as shown at 2t.
I claim:
