The closed top railway car body of the kind described herein, is formed of four units,.namely a pair of long-itudinalunits each forming a side andja longitudinal'half of the roof and a pair of end units, the saidunits having meeting edges adapted to be connected together. The present invention is more particularly concerned with the structure ofthe unit forming one side and a longitudinal half of the roof,

Referring now in detail to that embodiment M of the invention illustrated in the drawings, lfll iiindicate as a whole, one of a pair of longitudinal. units of the body and H indicates, as a Whole, one of a 'pair of endunits'assooiated with the. longitudinal units to form the body.

Each unit lllincludes a longitudinally extending sill member I2, a longitudinal side plate It and a longitudinal ridge member [4. The sill member is made from a so-called bulb angle used in car building and'includes a vertical flange l5 and an inwardly extending top horizontal flange IS. The side plate [3, as herein shown, is a Z'bar and includesa horizontal Web ll,.an inner downwardly extending verticalflange l8and an outer upwardly extending, inwardly curved flange L9. The ridge member I4 is preferably an angle bar with a vertical flange 29 facing upwardly and a horizontal flange 2i facing outwardly and slightly downwardly.

25 indicates, as a whole, the longitudinally spaced carlines of the unit, which extend downwardly and outwardly, from the ridge member I4, toward the side plate I3. As herein shown, each carline has an inverted channel cross section and includes a top web 26 and downwardly and outwardly extending side flanges 27-41 each having an out-turned margin 28. This channel cross sectional shape makes it possible to use a light gauge metal in the carline so that the weight is reduced to a minimum without sacrificing strength. The inner end of each carline is disposed under the flange H of the associated ridge member and is secured thereto as will later appear. curve conforming to the curvature of the flange I9 of the associated side plate. The web 26 of each carline stops short of said plate flange while the flange margins 28-28 thereof are made as extensions 29 that overlap the inner face of the inner flange I8 of the plate and are secured thereto as will soon appear.

In the outer end of each carline is a rigidifying or bracing knee 35 also of a channel-like cross section and including a web 3 I side flanges 3232 and an end wall 33. The web 3| of the knee engages the inner face of the web of the carline. The end wall 33 extends from the web toterminate as a flared out tail piece 34 engaged between the inner face of the side plate flange I8 and flange extension 29 of the associated carline. The manner of fastening the tail piece of the knee to the side plate and the manner of fastening the web 3| to the web of the carline will appear later.

Associated with the sill of each unit II! is a thick riser plate 35. As shown herein, said riser plate is so disposed that its outer face is flush with that of the vertical flange I5 of the sill. One way by which the riser plate may be attached is to offset the bottom margin 35 thereof at an inward and downward angle. When the edge of said margin is engaged on the horizontal flange of the sill I2 and the outer face of the riser plate is disposed in the plane of the outer face of the flange I5 of the sill, this provides a groove in which a line of Weld 38 is laid to substantially fill said groove.

39 indicates as a whole, the side sheathing for the unit. As shown herein the sheathing comprises vertically disposed relatively thin metal sheets 40. Each sheet, except those on each side of the door opening, is formed along one margin to provide an inturned, right-angled stiffening rib 4| including a flange 42. This rib is herein shown to be as deep as the furring strips 43 for the lining 44 and the depth of said rib is less than the depth of the web ll of the side plate. That margin of each sheet 40 opposite the stiffening rib is left straight and is made to overlap the first mentioned margin of the next adjacent sheet and is secured thereto as by a line of rivets 45.

The bottom margin of each sheet 40 overlaps the outer face of the top margin of the riser plate 35 while the stiffening rib 4i of said sheet terminates short of the top edge of the riser plate. To add rigidity to the connection of the sheets with the riser plate, I provide an angle gusset plate 46 with one flange riveted to the rib 4| of the sheet and with the other flange overlapping the inner face of the top margin of the riser plate 35. Rivets 41, extend through the bot- The outer end of the carline is made on a tom margin of the sheet, the top margin of the riser plate and the associated flange of the gusset plate. By means of this plate 45, a rigid connection is afforded between the sheet and the side sill through the riser plate. The riser plate, being relatively thick, withstands the corrosive effects of fluids used in cleaning the floor of the car, of which the unit forms a part.

The top end of the sheet 40 extends into a position and is curved to overlap the outer flange if) of the side plate to which said end of the sheet is attached by rivets 41 The top end of each stiffening rib is cut off below the side plate. A bracket having vertical and horizontal legs 48-49 is provided as a means attaching the side plate and the ribs 4| together. As herein shown, the vertical flange of the bracket is riveted as at 50 to the top end of the rib and the horizontal leg 49 engages the outer face of the inner flange of the side plate. flange 49, the flange I8 and a part of the tail piece 34 of the knee 38 to secure all of these parts together. Also, a rivet 52 passes through the flanges 49 and I8, the tail pieces 34 and one of the extensions 29 of the carline. A third rivet 53 is employed to secure the other extension of the carline along with the tail piece 34 of the knee brace to the flange I8 of the side plate. It is apparent that by reason of the structure described, the parts mentioned are rigidly secured to the side plate and are so coordinated as mutually to coact therewith to provide the stiffness and strength required at this point without undue weight.

54-54 indicates the roof sheets of the units and which are of thinner stock than that employed in the side sheets. These roof sheets have marginal parts which overlap in the planes of the carlines as best appears in Fig. '7 and rivets 55 pass through the said overlapping marginal parts and through the web 26 of the carlines to secure them together.

The bottom outer ends of the roof sheets extend beyond the like end of the carlines and overlap the top ends of the side sheets as well as x the top margin of the side plate flange I9, a line of rivets 55 securing the parts together. Also rivets 51 are employed to extend through the outer end parts of the roof sheet and the web of the associated carline along with the web 3| of the associated knee brace.

The opposite end margin of the roof sheets are formed to follow the flanges of the ridge member I4 to act as a flashing to insure a watertight connection for the ridge.

When two completed units I0IG are in operative position upon a car underframe, the flanges 29 of the two ridge members abut each other and a cap strip 58 is applied thereto and to the flashing margins of the roof sheets of the carlines of both units I0 together, splice bars 50 are employed. These splice bars are of inverted channel cross section and fit within the like cross section of the abutting ends of the associated carlines. The splice bars 60 include side flanges GI which engage the inner faces of the A rivet 5| passes through the flanges 21 of. the carlines and rivets 6-2 pass through the respective flanges. to secure the parts rig-idly together.

Of course, each unit Ill has an opening therein The margins of the side sheets adjacent the door openings are devoid of any stiffening rib but overlap the outer face of theelement. 63 and are suitablysecured thereto, At each end of the unit i i) isan end rib 64 of angle bar, with one flange 65 overlapping 'and secured to the associated end margin of each end sheet.

When two units Ill-Ill are mounted upon a car underframe, the other flange of the corner rib 64 overlaps the associated margin of the ends I lll and are riveted thereto. Said ends carry upright furring strips 66 to which the end lining is secured. In each corner, between the units and II is a corner furring strip 68 at which the linings 44-4 meet and to which they are suitably secured.

It is apparent that each unit It is a unitary structure, which when made as described, is relatively light in weight, but is strong and rigid. It cannot warp or twist out of shape either in the handling thereof as when shipped from its place of manufacture to its place of assembly upon an underframe, or when in use on the underframe of a railway car.
