9 Claims.

This invention relates to metallic structures in general and in particular to metallic structures provided with nonmetallic nailing blocks permitting the attachment of objects for bracing.

In the past, metallic structures, particularly railway box cars, have been constructed with wood linings to which blocking braces or other necessary lading retaining means could be attached but in the last few years attempts have been made to lighten car construction with the result that a certain number of so-called all-metal cars have been built making it impossible to attach blocking or braces. It is an object, therefore, of the present invention to provide a metallic structure having non-metallic nailing blocks removably secured to the structure.

A further object of the invention is the provision of a metallic structure such as a railway car having maximum cubic capacity with provision for anchoring of lading to the structure.

A still further object of the invention is the provision of a new and improved arrangement for attaching non-metallic nailing blocks to a metallic structure.

These and other objects of the invention will be apparent to persons skilled in the art from a study of the following description and accompanying drawing, in which:

Figure 1 is a sectional view taken through a side wall of a railway car and-showing the manner of attaching the nailing blocks thereto;

Fig. .2 is an inside elevational view showing the nailing blocks as attached to the side wall structure, and

Fig. 3 is a sectional view taken substantially on line 33 of Fig. 2.

Referring now to the drawing in detail, it will be seen that the improved arrangement of nailing blocks has been shown as applied to the side wall of a railway car of more or less conventional design. The car construction in the present instance consists of a side sill 2 to which the lower edge of side wall sheathing 4 is attached with its upper edge attached to a V-shaped lower or side Wall plate 8. The side wall is stiffened by flange channels 8 having web portion l0, flanges i2 and outwardly directed terminal flanges l4 adapted to be spot Welded or otherwise secured to the side wall sheathing. These side wall posts are preferably pressed with the lower end curving inwardly as at I6 for bracing attachment to the side sills, while the upper end is deflected inwardly to fall beneath the outwardly directed flange l8 of the lower or side wall plate. Any desired form of car roof 20 is attached to an upper or roof plate "22 having a flange portion 24 adapted to overlie and be secured to the outwardly directed flange of the lower side plate, thus joining the two plates to form a rigid plate. The side sill is of angular formation and adapted to support the flooring 26 with the joint between the sill and floor sealed by means of some plastic compound 28 which is also used to seal the lower endof the flanged posts above the wood filler block 30. The usual 2 end post 32 is attached to the side wall and to the end wall member 34.

The side wall sheathing which is located intermediate the flanges of the channel posts is pierced to provide a keyhole type of slot having an enlarged round portion 36 merging into a narrow slot portion 38. It should be noted that these keyhole slots are arranged in pairs with.

the narrow portions of adjacent keyholes directed toward each other. the side sheathing adjacent this cut out portion reinforcing plates 4!] are provided spot welded or otherwise attached to the side wall and each having keyholes cut therein exactly similar to the keyholes appearing in the side wall structure. These keyhole portions are so designed as to receive the head of a carriage bolt i2 through the round portion with the elongated portion of such a width as to engage the shank of the bolt, thus preventing outward movement of the bolt relative to the plates. In order to prevent the bolts from being inserted too. far into the keyhole slot and becoming lost in the hollow'post section a flanged clip member 44 has been provided having the outwardly directed flanges thereof Welded or otherwise secured to the reinforcing plate immediately back of the keyhole slot. It will be apparent that the clip members being imperforate and spanning the keyhole slots fully restore the strength of the sheet at the keyhole slots and also assist the reinforcing plate to resist bending caused by bolt tension. A nailing block 50 is provided having recessed openings 52 adapted to receive the nuts 54 by means of which it is held upon the bolts and anchored to the side wall or other metallic structure. In the present instance the nailing blocks have been shown as three in number, but it is obvious that more blocks could be used or that a single strip could be substituted for a plurality of blocks. By arranging the keyhole slots in pairs with the narrow portions of adjacent keyhole slots directed toward each other, it is possible to provide an arrangement preventing any possible shifting of the block relative to the structure, thus In order to stiffen preventing any accidental removal of the nailing blocks.

While the improved nailing block arrangement has been shown as applied to a box car of the so-called unlined type, it is obvious that the arrangement is equally applicable to double metallic sheathed cars as well as to any other metallic structures where it is desirable to attach nailing blocks to the structure. The invention has been described more or less in detail for illustrative purposes, but it is to be understood that various modifications and rearrangements of parts are contemplated as fall within the scope of the following claims.

What is claimed is:

1. In a railway car, the combination of a side sill, a side plate, a metal sheet connecting said plate and sill and forming the side wall of the car, said sheet having keyhole slots cut therein with the narrow portions of adjacent slots directed toward each other, bolts slidably locked in said slots, and nailing blocks secured to said sheet by said bolts and retaining said bolts locked in the slots.

2. In a railway car, the combination of a side sill, a side plate, a metal sheet connecting said plate and sill and forming the side wall of the car, channel posts on the exterior of the sheet and having their flanges secured to said metal sheet, sill and plate and forming a substantially closed box, keyhole slots cut in said sheet between the flanges of a post, bolts slidably locked in said slots, and nailing blocks secured to said sheet by said bolts. 1

3. In a railway car, the combination of a side sill, a side plate, a metal sheet connecting said plate and sill and forming a side wall of the car, keyhole slots cut in said sheet, channel posts having their flanges secured to said metal sheet on either side of the keyhole slots, bolts slidably locked in said slots, and nailing blocks secured to said sheet by said bolts and in turn retaining said bolts locked in the slots.

4. In a railway car, the combination of a side sill, a side plate, metal sheets connecting said plate and sill, reinforcing plates secured to the metal sheets, keyhole slots cut in said sheets and reinforcing plates with narrow portions of adjacent slots directed toward each other, channel posts having their flanges secured to said metal sheet on either side of the keyhole slots, bolts slidably locked in said slots, and nailing blocks secured to said sheet by said bolts and retaining said bolts locked in the narrow portions of the slots.

5. In a railway car, the combination of a side sill, a side plate, metal sheets connecting said plate and sill, reinforcing plates secured to the metal sheets, keyhole slots cut in said sheets and reinforcing plates, channel posts having their flanges secured to said metal sheet on either side of the keyhole slots, bolts slidably locked in said slots, guard means secured to said reinforcing plate and housing said slots to prevent loss of the bolts within the posts, and nailing blocks secured to said sheet by the bolts.

6. In a railway car, the combination of a side sill, a side plate, metal sheets connecting said plate and sill, reinforcing plates secured to the metal sheets, pairs of keyhole slots cut in said sheets and reinforcing plates, said keyhole slots each being formed by an oblong opening merging into a round opening and the oblong Openings of each pair being directed toward each other, bolts having head-s insertable through the round opening and shanks slidable in the oblong opening to lock the bolts in the slots, and nailing blocks secured to said sheet by said bolts and retaining said bolts locked in the oblong openings of the slots.
