CAR CONSTRUCTION.

Application filed April 22, 1927. Serial No. 185,723.

This invention relates to improvements in car construction.

In the so-called ore-carrying service of the Great Lakes, it is the standard practice to employ ore cars which are 24 feet from coupling center to coupling center, said cars being made up into trains and run onto the ole docks where the material in the cars is dumped into bins spaced 24 feet center to center. The material from the bins is in turn dumped into ore-carrying steamers.

Owing to the limitations thus placed on the length of ore cars, much difiiculty has heretofore been encountered in obtaining the necessary capacity and at the same time ohtaining the necessary space to accommodate the necessary draft riggings. As will be obvious to those skilled in the art, in order to obtain the maximum carrying capacity, the bolsters must beseparated as far as possible, which, in turn, reduces the available space from the bolsters to the striking plates of the car for accommodation of the draft riggings.

- In such cars, when an attempt has been made to utilize draft riggings of the normal or standard overall length of 24 and inches, great difliculty has been experienced in the insertion and removal of such draft riggings since there is insufficient clearance at the center plate to permit the vertical removal or insertion of the draft rigging with its usual yoke or yoke-acting means. 'Oonsequently, it has been necessary to remove the rivets securing the center plates in order to insert or remove such a draft rigging, which obviously involves a heavy labor expense as well as a considerable loss of time in the operation of the car. To overcome the difficulty mentioned, it has heretofore been sometimes suggested to utilize short draft riggings, but such draft riggings have numerous disadvantages and it is highly desirable that draft riggings of standard size and length be used if possible.

One objectof my invention is to provide a car construction, particularly an ore-carrying car, wherein the center plate arrange-- ment may be located at the minimum distance from the corresponding adjacent end of the car and so arranged that the insertion and removal of draft riggings of standard length, including the usual attachments thereof, may be accomplished with a minimum of effort and without the necessity of removing any rivets or other permanently attached parts of the car structure.

More specifically, an object of my invening area on the center plates is obtained While at the same time one of the plates is recessed or cut away so as to provide clearance for draft rigging parts for the insertion or removal of draft rigging parts, the cutaway portion of the platebeing compensated for by easily removable and attachable means.

A still more specific object of my invention is to provide a center plate structure for a car wherein the body bolster center plate is recessed for clearance purposes. The lesser bearing area due to the recessing of the plate is compensated for by the use of a removable and detachable shim that is adapted to interlock with the center plate member.

Other and further objects of the invention will more fully and clearly appear from the description and claims hereinafter following.

In the drawings forming a partof this i:

specification, Figure 1 is a longitudinal vertical section of the end portion of a car embodying my improvements. Figure 2 is a plan view of the structure shown in Fig. l as viewed on a line 22 and having some of the parts removed for the purpose of better illustrating the construction. Figure 3 is a detached plan view of the center plate shim shown in Fig. 1. Figure 4 is a sectional view of the shim shown in Fig. 3 and taken on a 1 line 44 of the same. Figure 5 is a fractional sectional elevational view such as shown in Fig. 1 illustrating a modified construction. Fig. 6 is a view similar to Fig. 5 illustrating another modification. Fig. 7 is a view similar to Fig. 5 illustrating still another modification. Fig. 8 is a view of a body center plate showing a modified construction wherein openings in the center plate are formed on both sides thereof instead pler carry iron at 12 having a wear plate 13 and supported by the bolt 14. At the bolster, a filler 15 is interposed between and riveted to the center sills and has attached to the underside thereof the customary bolster bottom cover plate 16. The center bearing structure comprises, broadly, a body bolster center plate 17, a truck bolster center plate 18, and an interposed shim or plate 19. In dotted lines, I have indicated the outlines of a cast yoke 21 of a standard length draft rigging, the key usually employed with said yoke and which passes through horizontally elongated slots in the center sills being shown in full. The

usual stop lugs

21 and 21 of the standard distance apart are indicated, it being understood that the front and rear followers of the draft gear proper will cooperate therewith in the usual manner. The draft rigging is supported in operative position by the saddle plate 21.

The body center plate 17 includes a fixed body portion 22 riveted to the body of the car 'as indicated at 23 and a bearing section 24,, said bearing section, which includes bearing face 25, being substantially circular in outline with a cutaway portion 26 which provides an opening in the body portion of the center plate and serves to give the bearing portion an irregular contour. The cutaway portion or recess 26 is in alignment with the draft yoke 21 when the latter is in normal position, so that the yoke can be inserted or removed vertically past the body and bearing portions of the center plate without the necessity of removing the center plate from the car. The vertical wall portion of the bearing portion of the center plates also have to withstand considerable thrust in the direction of movement of the car during movement of the car, and in stopping and starting, and consequently I find it desirable to compensate for the cut-out portion 26in the body bolster center plate by inserting a filler member to restore the circularity of the cen- 'ter plate, to provide a continuous solid abutment against which the vertical wall portion 'of the truck center plate will bear, and to compensate for the removed portion of the bearing area. The preferred manner of compensating for the cut-out portion is to provide a circular fiat shim, such as shown at 19 in Figs. 1, 3 and 4E, and to form integrally therewith a vertical projection 27 adapted to conform substantially to the shape of the opening 26 in the body center plate. In this manner the shim is locked relatively to the body center plate against turning. Said shim 19 is preferably strengthened with a continuous flange 28 which joins with the up standing projection 27 and in conjunction therewith provides a continuous circular bearing contour adapted to contract with the full area of the truck center plate. The shim center sills are indicated at 110, the bolster fillercasting at 115, the bottom cover plate at 116, the body bolster center plate at 117, the truck bolster bearing plate at 118 and the interposed shim at 119. In this particular modification, the annular flange around the shim, such as indicated at 28 in the first modification is omitted, the shim plate 119 being provided with an upstanding projection 127 adapted to enter the recess in the body bolster center plate 117, which is formed substantially identical with that shown in the first modification described.

In the modification illustrated in Figure 6, the center sills are indicated at 210, the filler casting at 215, the cover plate at 216, the body bolster center bearing plate at 217, the shim at 219 and the truck bolster bearing plate at 218. In this construction, the centering boss or sleeve 229 is formed on the shim plate 219 instead of on the truck bolster bearing plate, it being evident that said sleeve enters the corresponding recess pro vided on the underside of the body bolster center plate 217. In this modification also, the shim plate 219 is provided with an upstanding lug or projection 227 adapted to fill the corresponding opening or recess provided in the body bolster bearing plate 217 Wl11Cl1 is made the same as illustrated in the 'ment is substantiallyidentical with that shown in the first modification except that the shim plate 319 is provided with an upstanding sleeve or boss 329 instead of the same being provided on the truck bolster center plate 318.

p In the modification illustrated in Figure 8, the body bolster center bearing plate is of reversible type and to this end is provided with two recesses or cut-out portions e26 l26 at diametrically opposite points and of like contour so that either side of the plate may be presented nearest to the end of the car. 1t is obvious that corresponding changes will be made in the shim plate to be used therewith so as to compensate for the cutaway portions of the body bolster center plate.

I have herein shown and described what I now consider the preferred manner of carrying out my invention, but the same is merely illustrative and I contemplate all changes and modifications that come within the scope of the claims appended hereto.
