In the applicants Patent No. 2,007,272 and Other objects not specifically enumerated will Patent No. 2,007,273, there is disclosed a new be apparent to those skilled in the art as the and improved type of side sheet construction defollowing description proceeds. A better undersigned to increase the capacity of the car and at standing of this invention may be had by a conthe same time, protect the side stakes adapted sideration of the accompanying drawings in for use on slightly modified cars; namely those which:- which have the lower chord positioned outwardly Figure 1 is a fragmentary perspective view of a with the vertical flange thereof substantially in portion of a car wall constructed in accordance the maximum outer plane of the car. with this invention;

Whereas this is generally satisfactory, blank sheet of metal from which the side sheet it sometimes occurs due to the size of the sheets in Figure 2 is formed by bending and welding and the lack of control over the operation, that operations; the sheets are buckled or wrinkled or otherwise Figure 6 is a view similar to Figure 1 of a modidamaged so as to be unusable or at least to be fied form of the present invention; rendered unsightly and thus of less value than if Figure 7 is a'view similar to Figure 3, of the such damage had not occurred. 1 7 form of the invention shown in Figure 6;

In order to avoid the hazard of such damage Figure 8 is a view similar to Figure 5, of the in the manufacturing operation and in order to form of the invention shown in Figure 6.

simplify and improve the assembling processes By referring to the drawings, it will be noted for cars of this general type, it has been proposed that the wall construction illustrated comprises by Harry S. Hart to perform the bending operan upper chord l0 and a lower chord IL, In the ations on a smaller wall sheet element referred form ofthe invention illustrated in Figure 1, the

lower chord lies in an inward plane with the vertical flange thereof in substantially the same vertical plane as the vertical flange of the upper chord 10. The chords l0 and II are connected by side stakes I2 which may be of any suitable form but which in this embodiment are illustrated. as being of angle iron connected at top and bottom to the upper and lower chords respectively, by rivets, bolts, welding, or any other suitable attaching means. For this form of the invention, the side sheets may be formed substantially in accordance with the showing in Figures 3 to 5 inclusive. From an inspection of Figure 5, it will be noted that the side sheet is formed from a fiat blank sheet of metal !3 which is cut out at the top and bottom substantially in the .manner shown. In this form the cutout I 4 provides a central tongue I5, inclined portions l6, extending from the tongue, other inclines II, which extend upwardly and merging with the vertical cuts l8, adjacent the top. At the bottom, a somewhat similar cutout 20 is provided which forms a central tongue 2|, inclined edges 22, other inclined edges 23 and the vertical edges 24, adjacent the bottom.

When the plate is so formed, it is bent along the central vertical lines 2424 and 2526 so as to form a central groove on the outside of the sheet for receiving the side stake. The sheet is also bent along lines 27 so as to bring the inclines l6 and I! together and also bent on lines 28 to bring the vertical edges l8 in engagement with the inside of the tongue I5. When so bent, the meeting edges are welded so as to hold the plate in its final shape. At the lower end the sheet is further bent along lines 3U3Ei and lines 3l3| and again Welded in the manner previously described so as to provide the final sheet in the form shown in Figures 2 to 4, inclusive.

With the sheet 50 finished, which is designated generally 35, it may be applied to a car wall construction as shown at the right hand side of Figure 1. This is applied during the assembling operation of the car Wall and is connected to the upper and lower chords respectively, by rivets, bolts, or other suitable means, 35. Thereafter the side stake i2 may be applied in the central groove and secured by means of rivets, bolts, or other suitable securing means 31, to the upper and lower chords respectively. The side stake is also connected by means of bolts, rivets, or other suitable fastening means 38, to the inner surface 40, of the side sheets.

The present invention also contemplates the form of side sheet shown at the left handside of Figure 1, designated generally 40. This sheet in all essential details, is like the sheet 35 except that the side stake groove is not positioned centrally thereof. It is apparent that the side stake groove may be placed at any point in the width of the side sheet asconvenience may dictate. In all events, however, the various side sheets constituting the completed wall are designed of sufficient width to bring their edges in abutment as shown at 42 so as to provide a complete panel between side stakes. These abutting edges are then welded or otherwise secured in any desirable manner.

In the form of the invention illustrated in Figures 6 to 8 inclusive, the bottom chord 50 of the car is disposed slightly outwardly from the position illustrated in the form of invention shown in Figure 1, In this case, the bottom of the side sheets extends downwardly and is not bent inwardly as is the case in Figure 1, but on the contrary, the stake receiving groove is deflected outwardly so as to bring the bottom end of the stake outwardly for attachment of the vertical flange of the lower chord 56. In this form of invention, the side sheet which is designated generally 52, is made of a blank 54 of the type shown in Figure 8. The upper end of this blank is substantially the same as the upper end of the blank illustrated in Figure 5 and the same is folded and welded in substantially the same manner. However, at the bottom, a central tongue is provided which is slightly longer than the blank which has diagonal edges 58 formed by cutouts, which extend in the opposite direction from those shown at the bottom of Figure 5.

The angular edges 58 terminate in vertical edges 59 which are adapted upon bending of the blank, to abut against the side edges of the tongue 56. This blank is bent at the top along lines Bii5il and 5l6l and also along the vertical lines 6262 and 53-63. When bent and welded, the top of this side sheet forms itself in a manner similar to the side sheet of Figure 2, but at the bottom the tongue 56 is bent forwardly along the lines 54 and thence downwardly along the lines 65 so as to bring the edges together for welding. Upon welding, the finished sheet is substantially as shown at 52 of Figure 6. Here again, the adjacent sheets are of suificient width to bring their edges in abutment as at 68 so as to enable them to be Welded together to form a completed side wall construction.

As distinguished from the prior art, the side stake receiving grooves are formed by cutting, bending and welding and thus the two-directional pressing operation is eliminated along with the attendant dangers thereof. Furthermore, the side sheets are of relatively large size which minimizes the necessary welding to complete the entire wall.

It is to be understood that the inventioncontemplates sheets of any desired size so that very large sheets may be provided of suflicient width to embrace one, two or more side stake grooves whereby the necessary welding at the abutting edges of adjacent side sheets is reduced to a minimum.

It will further be understood that this type of side sheet is applicable to various types of cars to provide increased capacities therefor while at the same time, protecting side stakes against corrosion and damage in use, due to the lading. The side sheets may be readily removed, and replaced or may be applied to old or new cars as desired.
