s4 claims.v (C1. rcs- 409) This invention relates to railway car bodies and more particularly tothe manner of constructing the door casing and-attaching thesame to the car body.

One of the objects of the invention` is the provision of a new and improved door Vcasing fabricated from sheet metal in such mannertl'rat the lintel, threshold, and door posts will each be of boxlike construction thereby providing-a rigid support for the door and very greatly reinforcing the side wall ofthe car. f f I v.

Another object of the invention is kthe provision of a new and improved doorcasing construction in which the entire casing is of sheet metal with the parts secured together by welding.

Another object of the invention is the provision of a new and improved sheet metalI door casing construction in which the parts are welded together and to the underframe-and side walls of the car so that the entire root-sidewalls, and underframe will become 'lai rigidY unitary `struc ture.

A further object of the invention is the' provision of a carv body having a unitary door casing welded thereto in such a manner that the entire c rbolts, or rivets are employed, none of the welds structure may be assembled by welding.

A still further object of the invention is the provision of a new and improved unitarysheet metal vdoor casing that may be constructed and assembled with a minimum of expense and labor, that is rigid and durable and that requires a minimum of material. l v

Other and further objects and advantages of the invention will appear :from the following description taken in connection with the accom panying drawings, in whichf Fig. 1 is av perspective view of a'portion of a side of a car showing the inventioninco-rporated therein; I

Fig. 2 is a side elevation on a somewhat larger scale, with parts broken away;

Fig. 3 is a section on the line 3--3 of Fig.`2; Fig. 4 is a section on the-line 4-4 of Fig. 2; Fig.A 5 is a section on the line 5-5 of Fig. 4; Fig. 6 is a section on the line 6-6 of Fig. 2; Fig. 7 is a section on the line 'I--l of Fig. 2; Fig. 8 is a vperspective view -of a portion. of a side of a car showing the invention in position therein, with parts in section and parts broken away; and c f Fig. 9 is a vertical section through the door lintel showing a slightly modied form of construction.

In the construction of modern railway cars, the present tendency is toward the use-of more arrangement of the same in order that the structure may be properly fabricated. The car being c rial.

v difficult Awhere three or more thicknesses are iny .volved vIn the present invention, the `structure comprises the door posts or jambs 2I and 22, the

`and more sheet metal in the fabrication of vthe car.r Such structures are much' lighter than the older' conventional types of cars and are less expensive to build. The extensive use `of welding instead of .riveting results in a great reduction in 5 kthe `weight of the car as well as amarked saving in time, and'expense in building the same. But' the extensive use of welding necessitates the usev of specially constructed parts andthe proper made almost entirely from sheet metal welded together, certain parts must necessarily be sol arranged as to'give rigidity to the structure and at thesame time be' so arranged that they mayA be properly welded together.A

In order-to obtain the best Welds, it is necessary, or at least highly desirable, that the welds extend through two thicknesses only of the material. 1

l The present yinvention seeks to provide a construction in which the doo-r casing is so fabricated as to afford maximum strength and so arranged as to properlyreinforce the side of the car. It is framed into the car side and while no 25 for securing the partstogether extend through more than two sheets or thicknesses of the mate- Spot or line welding is extensively used in this relation althoughvarc welding is in comf3@ mon use also.

in thickness at the welds since welding is very 35 is so fabricated that the welds are between two thicknesses only of the sheet metal.

Referring nowtc the drawings, the reference characterll) designates generally a railway car having, atleach side thereof, aside sill Il, a subsill I2 rigidly secured to the side sill and: depending therefrom, a side plate I3, Fig. 6, of special formation which may be termed a flanged Z-bar, a plurality of carlines I4, roof sheathing I5, the;

. reinforced side posts I6, Fig. 2, and the sheathing or side wall Il of the car.

The wall Il is provided with a door opening I8 in which is secured the door casing I9 which 50 door lintel 23, and the door sill 24, Fig. 2.

The side sill II has its 'vertical flange 25 parposts and the door sill 24, as shown more clearly jamb 2|, which, for convenience of description,'

will be termed the forwardv jamb, comprises a specially formed member 28 which may be termed Z-shape in cross-section, Fi'g. 8,.ha'vingna web portion 29, an inner forwardly extending ange 3|, and an outer return bend 32 also extending forwardly. 'Ihe return bend 32 lhas its edge 30 bent forwardly, then outwardly'and then rearwardly and slightly outwardly to form; va channel 33 for` strengthening the door post and for receiving the forward edge of the doorfwhen the'same is closed, as shownvin dotted linesin Fig.- 4. In order to further reinforce the post and at the same time provide means to which the side sheathing 34 may be attached, an angle bar 35 is employed. The angle bar 35, Figs. 4 and 8, has an outwardly extending Aflange 35 weldedto the web of the channel 33 and has a forwardly lextending flange 31 to which the side sheathing 34 is secured, as shown more clearly in Figs.' 4 and 8 of the drawings. The Vflange 31 is offset inwardly below the sheathing 34 as at 40, Fig. 6, to engage the flange 25 `of the side sill I I to which it is welded. The lsheathing 34 is welded to the vertical ange 25 ofthe side sill for rigidly connecting the parts together. The lower endof the web 29 is slotted as at 38, see Figs. 6 and 8.Y

for receiving the vertical flange 25 of the Side sill and secured therein by suitable weld. The lower end of theweb 29 rests on the inwardly vextending horizontal -ange 39 of the side sill 1v|| and is adaptedto be welded thereto. ,d

The lower end of the portion forming the channel 33 and the lower end of the angle bar 35 rest on and are welded to an angle bar 4I forni-- ing the track or door support which is in turn connected to the side and subsills I I and I2 as by anarc welding.l The track member 4| has the horizontal flange 42 for constituting a track or support for the door 43, Figs. 4, 7 and 8, and a vertical flange 44 for` stiffening or reinforcing the track.

In'order to strengthen the corner formed by the door posts 2| and the side sill, a box gusset or lbrace member 45 is employed. This member has avertical flange 46, Figs. 4, 5 and 8, which is spot welded to the web 29 of the door post 2| and a horizontal or bottom ange 41 that rests on and is welded to the ange 39 of the side sill I I. `'Ihe gusset `is alsoprovided with side flanges 48 and v49.` The inner side flange 48 is welded to the flange 3| of the door'post 2| and the outer side ange 49 is'welded at its forward portion to the flange 25 of the side sill |I, as indicatedat 5|, Figs. 4 and 8. I

The upper portion of the outer side flange 49 is cut away on av curve as shown in dotted lines in Fig. 8 to afford clearance for welding the flange 31 of the angle bar 35 to the flange 25 of the side sill I below the sheathing 34, as indicated at 53 in Fig. 2. By cutting out this p0rtion, it will be seen that only two layers or sheets of the material are welded together and this vcutout portion permits welding at a point adjacent the lower end of the flange 31.

The upper ends of the door posts or jambs are ing flange 51 for'supporting the carlines I4 to which they are welded. AThe'flange portion 58 ofthe angle 55 extends downwardly parallel with thefvertical flange 59 of the side plate I3 and forms with the flange 59 a channel for receiving 'the -reduced portions of the upper ends of the side posts 2| and 22. The upper end of the side posts 2| is notched as at 6|, Fig. 8, to enable it to enter this channeL- n The ange 31 of the angle bar 35 is in vertical alignment with the "downwardly extending flange 59 of the side plate I3, Fig. 8, and the .channel formed bythe

flanges

58 and 59, Fig. 6, is of `sufflcient width.' to also receive the upper end of the sheathing 34 alongside the door post as indicated more clearlyin Fig. 8 of the-drawings.

An/angle bar-weather strip 62 has its horizonf vtal ange 63 resting on the upper end of the angle bar 35 and the upper edge of the portion of the bar 2'8 formed by the notch 6| and is welded thereto. This angle" bar merely provides a weather protection forthe door guide 64 whichY door lintel 23 as shown in Fig.l 6. y Y'Iuher door 43 is provided with theY usual door guide members 66 for vengaging'in the channel in turn is attached to the 'outer' flange 65 of the 7 "of the drawings. post is notched as at 61, Fig. 8, to provide clearance for the depending flange 68 of the weather strip 62. v I

4Albox gusset or brace 69,'Fig. 8, similar to; the gusset 4 5, is'pro'vided in the corner formed by the upper ends of the doorl posts and the side plate. Since this gusset is substantially the samev as that that has already been described, it

is lnot thought necessary to repeat the `descrip-r tion'.

The horizontal flange portion of the gusset 69 is welded to the horizontalportiorr'Ily of the side ,plate as indicated at 12 in Fig; 8 of the 'drawings andthe cut-away portion provides clearance for welding the upper edge of the sidez sheet 34 to the depending flange 59 of the side plate as indicated at 13 in'Fig. 8 of the drawings. 'I'he inner side of the gusset iswelded to an outwardly offset portion of the fiange 582s shown `at14inFig.3.

The door post2f2`isfshown vconstructed slightly different from the door post 2|. "This post comprises an angle bar 15, see Fig. 8, having a rearwardly extending angef' 13 and 'anoutwardly` extending ange 82,A and 'anchannel bar,y 11 .hav`

ing one flange 1 8 extending parallel with 4the side sheathing 34 to which -it is welded. The channel 11Yis provided'with a short outwardly and rearwardly extending ange 19 for engag-` ing a keeper 8| of the door 43, Fig. 4, when the door is closed. The channel'bar 11 has its web portion connected to the outwardly extending flange82` of the angle member15 and this angle bar and the channel member 1'I together form a box structure consituting the side post 22 of formed by the guide 64, as clearly shown in -ZIig.u

The upper fend of the door' of its flanges cut away to a curve for affording clearance for this purpose-as described above.

'Ihe upper end ofthe post 22 is secured vto the

flanges

58 and 59 in a manner similar to that described in connection with the attachment of the upper end of the post 2|, the parts being so constructed that they' may be connected together lby spot welding'without the necessity of welding through more than two sheets or layers of material.

The door lintel 23r is in theform of a channel member having'its` outer flange extended to form supporting means for thedoor guide 64 andextends between the two postsl and is welded to ,the

flanges

59 and 58 for holding thesaine in ber 84 in a manner similar to that alreadyde-` scribed and it is not thought` necessary to' repeat the description at this point. Y

The side posts |6 of the car are built up structures from sheet metal. One portion 8.5 is integral with the outside sheet metal sheathing, as clearly shown in Figs.' 3 and 4 of thev drawings, and is formed by bending one of the edges of each plate of the sheathing 34 `to Z-forrn and slightly offsetting the same inwardly as shown at 86V for receiving the edge of an adjacent sheathing plate to which it is welded. This portion 85 is reinforced by an angle bar 67, Figs.l 2 and 4, which is welded thereto to form the post I6. The angle bar 81 terminates short of the side plate I3 as shown by the dotted line 88, Fig. 2. The lower end of each side post terminates adjacent to the side flange 25 of the side sill and is secured to this flange by lan attaching bracket 89, Figs. 2 and 4. The bracket is channel'form and nests in the post I6 toy which it is welded. The lower end of the attaching bracket 89 extends below the side post alongside the flange 25 of the side sill and has its outer side flange welded thereto.

In order to further reinforce and rigidify the door casing and car side surrounding the door casing, a horizontally arranged pressed channel bar 9|, Figs. 2 and 4, is secured between the side post I6 and the corresponding post of the door casing at each side of the casing. This channel bar has its flanges 92 turned inwardly and the ends of the web portions 93 are welded, asv by an arc weld, to the flange 16 of the door post and to the adjacent flange of the side post so that this web portion is in the plane of these flanges.

By means of this arrangement, the door casing is not only rigidly held in position, but the entire car side is rigidly reinforced.

In Fig. 9 is shown a slightly modified arrangement of the door lintel. This form of construction differs from that previously described in The opposite end of the lintelV 'IV-'his arrangement affords a stronger connection between the lintel and the door post than that in which the partsA are welded in abutting relation as previously described.

It is thought from the foregoing taken. in coni nection with the accompanying drawings that -they construction vand operation of my device will be apparent to those skilled in the art, and that'changes'in size, shape, proportion and. details of construction rmay be made without departing from the spirit and scope of lthe appended claims.
