CONSTRUCTION OF RAIL'WAZY WAGONS AND THE LIKE.

Application filed September 19, 1925, Serial No. 57,472,

This invention relates to improvements in the construction of bodies of pit tubs, railway wagons vans and the like, and consists in forming them of metal plates adapted to be held rigidly in position by improved forms of sliding joints.

The object of our said invention is to provide a body which can be quickly assembled or taken. to pieces for repairs, and of which yarious types and sizes can be constructed from metal plates of a. standard size or sizes, thus enabling their manufacture to be carried out on mass production lines.

In describing this invention reference will be had to the accompanying sheet of drawings upon which Figure 1 is a part sectional elevation of a wagon body constructed according to our invention.

Fig. 2 is a section showing how the bottom plates are turned up vertically to form a connection to the side plates;

Fig. 3 is a section through a joint to be hereinafter described made up of four thicknesses of metal showing also a T-section member to be hereinafter referred to;

Fig. 41 is an elaboration of the joint shown in Fig. 3 made up of six thicknesses of metal;

Fig. 5 is a further elaboration made up of five thicknesses;

Fig. 6 is a section through the edge of a plate bent over on itself four times;

Fig. 7 is a section through a joint made by bending two corner plates on themselves and sliding them into one another;

F ig. 8 is a section through a joint formed by sliding a specially bent side plate over a T-section knee as will be hereinafter described.

In carrying out our invention we form the bottom of the wagon body of any desired number of plates adapted to be joined by means of lap joint 10, Figure 1, or by sliding U section joints of the kind described in our prior British Patent No. 16 1088.

The bottom plates 9 are turned up vertically round the edges to form a connection to the side plates 1& as shown in Figure 2. The side plates are joggled, cranked or recessed as shown at 1 1 to receive the vertically turned up portion of the bottom plate, the two then being bolted or riveted together giving a flush outer surface; alternative and in Great Britain September 19, 1824.

ly the joints may be similar to those hereinafter described.

The sides of the wagon are each formed of any number of plates, 14%, say for example three excluding the door, the plates being jointed together by means of a plain U-sec tion bend as shown in Figure 3, or elaborations; thereof as shown in Figures 4 and 5, thus giving a stronger joint. The sides are reinforced by T-section knees 11 at each side of the doorways. The ends of the side plates 14 are bent U-shape-to slide over the inner flange of the T portion as shown at let" Figure 8. The bottom of the U is projected beyond this flange and is recessed at 14 to receive the door 13.

In assembling the wagon the bottom plates 9 are joined together vand the knees 1.1 are then fixed thereon. The side plates 14 extending from the doorway to the end of the wagon are now slid on to the T-section knees 11 forming the joint shown in Figure 8. The plate 146 below which the door is fitted is next slid into position forming the joint shown in Figure 3. This plate is preferably bent over on itself four times along the bottom as shown in Figure 6 to form a stiffening member where the door stops are lined to the wagon. The bottom plate where the door is fixed is turned under and then preferably bent over on itself three times.

At one end of the wagon an end plate 16 is preferably slid into flanges of each of the side plates 14 to form a four-ply joint Figure 7, or an elaboration of this joint as shown in Figures 4 and 5 may be employed. The complete end of the wagon is made up of any number, say for example three plates, which may he slid or lipped to each other by any desired joint.

The other end of the wagon may be formed as a door 17 and the side plates suitably bent over and bolted or riveted to the T-section knees as shown in Figure 1. The bottom plate is also turned up and bent over. The door 17 is suitably stiffened at 17 and hung on a roller bar 18 passing through an eye bolt and through the top belt or turned over edge 14 of the plates 1%; it may be conveniently secured by means of an external nut and an internal lock nut.

The top edges of the plates are bent over on themselves four times to form a stiii'ening top belt as shown inverted in Figure 6 and where the joints in the plates make it desirable a tab may be left on each plate to it over the top edge of the adjoining plate, not shown upon the drawings.

Diagonal braces as shown in dotted lines at 19, Figure 1, may be fitted. if desired, to prevent the side plates from buckling, also cleats 20, Figure 1 may be fitted into the fast end corners of the wagon.

Doors may be provided in the bottom if desired; further a wooden flooring; may be fixed on the top of the metal flooring and doors provided in the wooden floor, a suitable opening being left for clearance of the wooden doors. The number of bends or thicknesses of metal in the various joints or stiffening pieces may be increased or reduced as desired, and any of the plates may be thicker than the others where greater strength may be required.

The body may be attached to a steel or wooden undertraine and conveniently bolted or riveted to same.

Having now described our invention what we claim as new and desire to secure by Letters Patent isz A metal body, comprising a bottom made up of a plurality of plates united together, said bottom being turned up around its edges, side plates having their lower edges ott'set inwardly thereby to fit within the turned up edges of the bottom, T-seetion knees supported on said bottom for rein forcing said side plates, some of the side plates having along one of their vertical edges a U-shaped portion adapted to engage and slide over one of the flanges of said knees, the said U-shaped portion being wider than its engaging flange and recessed beyond the flange "tor the reception of a door-forming; plate, the organization being such that the exterior surface of the body is substantially flush on all sides.

In testimony whereof we have signed our names to this specification.

ALBERT LESLIE \VRIGl-I'l. FRANCIS ISAAC SMEDLEY.
