11 Claims.

This invention relates to flat car underframe structures or the like for railway cars, and is particularly directed to the stake pockets and the arrangement and manner of forming and at- 5 taching said stake pockets to the underframe structure, and is a division of our copending application entitled Stake pocket for cars, filed March 20, 1936, Serial No. 69,846.

The stake pockets for receiving the lower ends of the stakes in position in spaced relation along the sides and ends of the car have been formed heretofore of cast or pressed metal and usually attached to the flat side surfaces of the side or end sills of the car underframe by means of bolts or rivets. When the car is loaded the stake pockets are subjected to enormous strain produced by the leverage pressure of the lading on the extending stakes of the car, which results in the connections of the stake pockets with the underframe becoming loose, or the stake pockets breaking olf. The loosening of the stake pockets further has the disadvantage of allowing moisture to collect around the bolted or riveted connections thereby allowing corrosion to set in very rapidly.

One of the objects of our invention relates to forming the stake pockets of rolled sheet metal adapted to be attached directly to the car underframe by welding.

Another object of our invention relates to forming the stake pockets in such a manner that theyv will be more securely braced when attached to the car underframe.

35 A further object of our invention resides in the manner of reinforcing the intermediate portion of the stake pocket.

Another object of our invention is to provide a stake pocket that can be attached to a flanged 40 or flat surface of the car underframe.

Having thus given a general description of the objects of our invention we will now in order to make the invention more clear refer to the accompanying two sheets of drawings which form 15 a part of this specication and on which like characters of reference indicate like parts:

Figure l is a top plan View of slightly more than one-half of a car underframe illustrating i0 the application of our invention.

Fig. 2 is a detail top plan viewof a portion of a car side sill with one of our improved stake pockets attached thereto drawn on a larger scale.

Fig. 3 is a longitudinal section of the portion 5 shown in Fig. 2 taken on the line 3-3 of Fig. 4.

. Fig. 4 is a side elevation of the enlarged portion shown in Fig. 2.

Fig. 5 is a vertical section taken on the line 5-5 of Fig. 4, and

Fig. 6 is a vertical section through the end sill 5 taken on the line 6-6 of Fig. 1.

Referring now to the various characters of reference on the drawings the numeral I indicates the car underframe as a Whole, 2 the center sills,

3 the side sills, 4 the bolster, 5 the cross ties or 10 bearers and 6 a cover plate attached to the top edge of the end sill 'l and adapted to 'extend in-r wardly therefrom and provided with a flanged edge as at 8, the lower end of which is bent inwardly at right angles thereto and adapted to 15 form a seat for supporting the end of the car floor. A

As illustrated in the drawings the side sills 3 are constructed of rolled I-sections with flanges 9 extending laterally therefrom along the top and bottom edges, although these side sill members may be of other section, as channels, Z-bars, or angles, or they may be made of pressed or of cast metal if desired without departing from the 2 spirit of our invention. .5,

The stake pockets attached to the side sills 3 of the underframe at spaced intervals are formed or rolled pressed sheet metal, each having a U-shaped portion IU forming the stake pocket, the legs II of which are parallel for a portion of their length and connected together by a reinforcing rib I2, which is welded to the legs I I as at I3. The ends of the legs II are formed with outwardly inclined or splayed extensions I4 having their ends welded to the web of the side sill as at I5. The upper surfaces of the leg extensions I4 are inclined, or shaped to conform to the contour of the underside of the upper out- Wardly extending flange of the side sill and is 40,-,

welded thereto as at I6.

In forming the extensions I4 of the legs splayed in the manner shown, a more desirable bracing effect is obtained than if the legs were made straight for the entire length. To further stiffen and brace the stake pockets laterally, brackets Il. formed of plate metal are welded to the opposite sides of the pockets at an intermediate point as at I 8, the inner ends of said brackets being Welded as 5 at I9 to the top of the side sills 3. By this construction a very strong and rigid construction is' obtained, the stake pockets being substantially integrally connected to the side sills will not become loose and allow moisture to collect and ,55

produce corrosion between the connections as in the case where bolts or rivets are used.

The stake pockets 2li at the ends of the car are formed and attached in a somewhat different manner. These stake pockets are U-shaped, the legs being parallel to each other throughout their entire length. The ends of the legs are welded as at 2l directly to the inner face of the end sill l, the rear end of the stake pockets engaging the vertical wall of the flange and welded thereto as at 22.

Openings 23 are formed in the coverv plate 6,

which registers with the stake pockets The upper end of the stake pockets are gage the under side of the cover welded thereto as at 24.

In this construction a very is obtained and the stake pockets arey securely held in position between the rear wall of kthe end sill l and the vertical wall of flange 8. The sides of the openings 23 in the cover plate further help to support the stake when in position.

As illustrated the stake pockets are formed of pressed metal, but they can be formed of cast metal if desired and then welded tothe underframe in the manner above described. y

Although we have shown and described our invention in considerable detail, we do not wish to be limited to the exact construction vshown and described, but may use such substitutions, modifications or equivalents thereof, as are embraced within the scope of our invention, or as pointed out in the claims.
