8 Claims.

The invention relates to railway freight cars preferably of the house or rooted type and has for its object to provide means for protecting the wooden floors now in general use in such type of equipment, which means will not interfere with the securing of blocking to the wooden flooring, to which the lading is secured.

Another object of the invention is to provide a metallic protecting sheathing which rests upon the wooden flooringof the railway car and is provided with apertures or perforations so that the car lading may be nailed or otherwise secured to the flooring through the apertures.

Another object is to shape the apertures so that they are long enough to provide a relatively large area for nailing and are relatively narrow so that the wheels of loading trucks or shoes of workmen will not get caught therein.

Another object is to form the sides of the elongated apertures with stiflening flanges to prevent the edges of the apertures from curling up and also to stiffen the sheathing as a whole against buckling. These stiflening flanges may project downwardly and be imbedded in the wooden flooring to help hold the sheathing in place or they may project upwardly so as to provide means to prevent slipping. I prefer to project some flanges upwardly and some downwardly.

The apertures are preferably positioned in staggered relationship with the end portions thereof overlapping each other so that the several flanges of the several apertures cooperate to reinforce and stiffen the sheathing.

Another object is to shape the elongated apertures with non-parallel sides to provide relatively narrow end portions and a relatively wide middle portion so that the edge of the plate around the apertures will have a tendency to lie flat instead of bending up.

Another object of the invention is'to provide a metallic sheathing whereinsome of the elongated apertures are positioned with their long dimension parallel to the short dimension of some of the other apertures and to provide said 5 elongated apertures with flanges along their sides which are substantially parallel with each other for use in driving the flanges into the wooden floor.

' In the drawings:

Fig. 1 shows a floor plan of part of a railway box car equipped with my floor protection.

Fig. 2 is a section on line 2-2 of Fig. 1. Fig. 3 is a. section on line 3-3 of Fig. 1. Figs. 4 to 11 inclusive show various forms of apertures in the metallic sheathing area of opening is provided for nailing In the form or my invention illustrated, the usual parts of thecar are shown, such as the center sills 2, side sill 3, door posts 4 and wooden flooring 6. The wooden floor 5 usually comprises a plurality of wooden shiplapped or 5 tongued and grooved boards extending laterally of the car which are secured directly or indirectly to the center sills 2, side sill 3 and floor stringers (if used).

My metallic sheathing I rests on the top of the 10 wooden floor 5 and is preferably secured thereto by bolts, screws or nails.

I preferably provide an elongated substantially diamond shaped aperture iii-l l-l2-l3--il wherein the middle thereof is relative wide 5 with end portions tapering to points or r unded terminals. By this arrangement a very l large but at the same time only a relatively small thing may penetrate the aperture. This shape of aperture 20 presents substantially convex sides which do not have a tendency to kick up. v

The sides of the aperture, or parts thereof, are

' provided with stiifening flanges which may project upwardly to provide anti-slipping means or 5 may project downwardly and be imbedded in the wooden floor to hold the sheathing down and from moving parallel to the top of the wooden floor. These flanges are preferably positioned parallel to the grain of the wood so that they 30 may be easily driven into the wooden flooring.

The flanges of some of the apertures may project upwardly and the flanges of other apertures may project downwardly for the purposes specifled, and in fact, the flanges of a single aperture 35 may project upwardly and downwardly and come within the scope of the invention.

Figs. 4 and 5 show my preferred form of aperture, wherein Fig. 5 is a section on line 5-5 of Fig. 4. The elongated aperture in has a rela- 40 tively wide middle part with parallel sides is with the sides i6 of the end portions merging into pointed ends iii. .The parallel side portions ii are provided with pointed or rounded flanges 20. 45

- Figs. 6 and 7 show a modified form of aperture (Ii) wherein Fig. 7 is a section on line 1-1 of Fig. 6. The sides of the aperture are provided with flanges 22 following the contour of the side edges of the aperture and merging (24) 50 into the sheathing adjacent the opposite ends 26 of the aperture. This aperture is formed by slitting the plate along line 1-1 from 30 ton and forming the flanges of the material between the sides oi. the aperture and this slit. 66

Figs. '7 and 8 show a modiflcation wherein Fig. 9 is a section on line 99 of Fig. 8. This elongated aperture I2 is curved with the convex edge 34 thereof formed with a flange 36 extending.

may be positioned in parallel rows with adjacentapertures positioned normal to each other for overlapping relationship, as shown to the left in Fig. 1.

Figs. 10 and 11 show a modification wherein Fig. 11 is a section on line HII of Fig. 10. The preferably elongated apertures are substantially rectangular in shape and are positioned with the longitudinal axes of one group thereof substantially normal to the axes of another group thereof, as shown on the left side of Fig. 1. The apertures l3 of one of these groups are provided with flanges 40 at the long sides 01' the rectangle and the apertures of the other group are provided with flanges 4| at the short sides of the rectangleso that the flanges 40-41 of all of the apertures are substantially parallel with each other. The metallic sheathing I is preferably laid upon the wooden floor 5 with the flanges extending substantially parallel with the grain of the wood so that they may be easily driven into the wood. Y 4

In Figs. 9 and 10, I have shown saw tooth flanges 40 which when projecting upwardly form an eiilcient non-skid construction and when projecting downwardly can be easily driven into the wood.

The accompanying drawings illustrate the preferred form of the invention. though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modiflcations thereof, within the scope of the claims, will occur to persons skilled in the art.

I claim:
