11 Claims. 1

This invention relates to freight car construction and particularly to the construction of railway house cars at and adjacent to the door posts.

In accordance with the present day construction of railway box cars 6" X31/2 x angle side sills are employed which extend from end to end of the cars. The side sills in the case of house cars which have wider than usual door openings asin automobile box cars and some box cars, are reinforced by means Aof 15" 40# channels whose upper flanges are riveted to the horizontal legs of the side sills. IThe reinforcing ,channels extend across the door openings' and for a suiiicient distance beyond the doorposts. yThe vertical legs of the side sills are cut down to a height of 2 in the door openings regardless of whether the 6" or the 3l/2 legs are disposed vertically. y

In this construction a further reinforcement is provided at and adjacent to each door post by means of a gusset formed from a 1A" plate secured'to the door post by seven rivets in single shear arranged in a vertical row and to the vertical leg of the side sill by twelve rivets in single shear arranged in two horizontal rows. Also the door post is secured `to the vertical leg of the side sill by two rivets which are independent of the gusset.

Frequent failures occur in these cars embodying this construction. Fractures develop in the 2 vertical leg of the side sills adjacent to the forward door posts beginning at the top edge and extending progressively through the reinforcing channels. The rivets securing the 'gussets and the door posts to the vertical legs of the side sills particularly adjacent to the forward door posts work loose or are sheared. And the rivets securing the reinforcingl channels to the horizontal legs of the side sills work loose with consequent development of fracturesin the horizontal legs of the side sills and upper horizontal flanges of the reinforcing channels between the rivets.

It is the prime purpose of this invention to overcome these difficulties of present day construction of box cars.

A further object isto provide` a construction for house cars which shall increase the strength of the side sill structure at the door opening adjacent to the doorposts. i i A further object is to provide a construction for house cars which shall increase the strength of the connection of the sideA sill structure to thecarside construction at the door posts.

A further object is to provide a construction for house carswhich shall increase the strength of the connection of the door posts to the Side sill structure.

A further object is to provide a construction for house cars which shall secure an increase in the strength of such cars at and adjacent'to the door posts by utilizing connections which place rivets in double shear.

A further object is to providea construction for house cars which shall obtain a substantial increase in the thickness of the construction in the door opening adjacent to the door posts.

A further object is to provide a construction for housecars which shall obtain a substantial increase in the moment of inertiar and section modulus of the construction. y n Y v A further object is to provide, a construction for house cars which shall utilize gussets to realizeV a substantial increase in the strengthv of the connection between the door posts and side sills and side sill reinforcements and. prevent tearing of the side sill and side sill reinforcements in the door openings of such carsadjacent to the door posts. Y *l Other objects of the invention will become clear as the description thereof proceeds. j Y.

In theY drawings forming part of this specication:

Fig. l is a partial elevation showing a construction ,embodying the instant invention-lat a forward door post of a house car, a portion being broken away -to illustrate certain parts of the construction more clearly.

Fig. 2 is a vertical section taken of Fig. 1.

Fig. 3 is a horizontal section taken on line 3--3 of Fig. l.

Fig. 4 is a vertical section taken on line 5- of Fig. l.

Fig. 5 is a horizontal section taken on li'ne 5--5 of Fig. l.

Fig. 6 is a horizontal section taken online on line 2 2 Vi--G of Fig. l.

In the drawings a preferred embodiment 'of the invention is shown at the lower forward portion of a door opening l0 formed in the side Il of a railway house car. While the invention is illustrated only at the lower forward corner of the door opening, it is preferred that it be utilized as well at the lower rear corner of the doorvopening.

Since the construction embodying theinvention is similar at both of these corners of the door opening, it is not believed to be'necessary to illustrate the construction at the lower rear corner of the door. However, this construction'will bvecome readily apparent ,by viewing the drawings from the reverse side. *i

The carside Il embodies a front door post I2 which comprises a Z-shaped member so arranged that its web I3 extends longitudinally and substantially in the plane of the carside, its flange I4 extending outwardly and its flange I5 extending inwardly. The door post illustrated also comprises an angle member I6 having an inwardly extending leg I'I secured as by means of rivets I8 to the flange I5 of the Z-shaped member I2 and a longitudinally extending leg I3 which is in alinement with the web I3.

The carside also embodies an angle side sill having a vertical upstanding flange 2| and a horizontal inwardly extending flange 22. Within the door opening the upstanding flange 2| is cut down in height as indicated at 23 so that it terminates substantially in the upper plane of the car floor 24. The side sill 20 extends substantially from end to end of the car and is reinforced across the door opening and for a sufficient distance Vbeyond each side of the dooropening by means of a channel member 25 arranged with its web 26 vertical and upper and

lower flanges

21 and 28 extending inwardly. Metallic sheathing 29 forms part of the carside and is secured by means of riveting to the web I3 of the door post I2 and to the upstanding leg 2| of the side sill.

In order to adequately reinforce the construction hereinabove described at and adjacent to the door opening, the instant invention utilizes inner and outer gusset membersB and 3 I. The inner gusset member 30 is secured to the inner face'of the web I3 as by means of rivets 32 and to the inner face of the longitudinally extending leg I3 as by means of rivets 33. The inner gusset member 30 is secured to the inner face of the upstanding flange 2| of the side sill by means of a double row of rivets 34.

The lower margin of the inner gusset member is provided with an inwardly extending horizontal flange which is secured as by means of rivets 36 to the horizontal flanges 22 and 2'I of the side sill and side sill reinforcement, respectively. As more clearly shownin Figs. 1. and 5 ofthe drawings, the horizontal flange 35 of the inner gusset member is extended into the door opening and within the opening the inner gusset member is cut down in height as indicated at 31 so that it lies substantially in the upper plane of the car floor. (See Fig. 4.)

The outer gusset member 3| is secured by means of the

rivets

32 and 33 to the outer face of the web I3 and leg I9, respectively, and to the inner gusset member 3|] thereby placing the

rivets

32 and 33 in double shear. The outer gusset member 3| is also secured by means of the rivets 34 to the outer face of the upstanding ange 2| of the side sill. Thus the rivets 34 which also secure the inner gusset member 30 to the upstanding ange 2| of the side sill are placed in double shear. I

The outer gusset member 3| beyond the door opening is extended downwardly as indicated at 38 and is secured as by means of rivets 39 to the outer face cf the web 26 of the side sill reinforcement.

The outer gusset member is also extended along the door opening I0 as indicated at 40 and is also secured to the outer face of the web of the side sill reinforcement as by means of rivets 4I. The latter extending portion of the outer gusset member terminates substantially in the upper plane of the car floor as indicated at 42 and is secured to the outer face of the upstanding flange of the side sill by means of the rivets 34 which secure the extending portion of the inner gusset member to the inner face of the flange 2|.

By virtue of the invention the moment of inertia and the section modulus of the carside construction has been substantially increased. There has been obtained also a substantial increase in the thickness of the construction in the door opening inasmuch as the inner and outer gusset members are extended into the door opening. Moreover, the construction is such that the securing rivets are placed in double shear.

To avoid conflict between the inwardly extending flange I5 and leg I'I of the door post and the inner gusset member 3D, the flange I5 and leg II Vare terminated above the gusset member as indicated at 43 and 44. The web I3 and the longitudinal leg I9 are continuous, however, and are extended so as to terminate above and adjacent to the upper edge of the upstanding leg 2| of the side sill as indicated at 45 and 46. While the web I3 is copedas indicated at 41 to conform to the cope 48 in the leg 2|, the outwardly extending flange I4of theZ-shaped member of the door post is extended downwardly below the door opening as indicated at 4S and is preferably welded to the outer gussetmember 3 I. y f

To compensate for the loss of strength resulting from the removal of the inwardly extending flange I5 and legl I'I, a plate ,member 5I) is disposed between and secured as 'by means of rivets 5I to the inwardly extending ange I5 and leg I'I as shown more clearlyI in Figs. 1 and 3 of the drawings. For this purpose the angle member I6 is offset as indicated at 52. The reinforcing plate member 50 is extended downwardly to the inwardly extending ange 35 of the inner gusset member to which it is secured as by means of welding. The offset 53 formed in the reinforcing plate member 50 is for the purpose of avoiding conflict between this member and the rivet R. It will be understood, however, that where such conflict does not occur, the reinforcing member 50 will be straight throughout. This member not only compensates for the loss of material occasioned by the removal of the indicated portions of the flange I5 and leg I1 but also serves to resist outward bulging of the carside at the door post. The rivets 5I, moreover, are in double shear.

The disclosed construction has the further salutary effect of removing substantially all` tension from the vertical rivets which secure the horizontal flanges of the side sill and side sill reinforecement together. The stress to which these rivets are subjected is essentially a shear stress whose unit value is materially reduced since they are placed in double shear by being driven through the horizontal flange of the inner gusset member.

It will be understood that the disclosed invention is not limited to the type of door post illustrated in the drawings but is capable ofuse with the various types of door posts employed in house car construction. For example, the door posts may be formed of the Z-shaped member alone without the separate angle member, or of aA W- shaped member, or the substantially channelshaped A. A. R. 4type `door post may be used. Again, any of the known types of welded door posts may be utilized, such as the door post formed of a channel-shaped member and a plate member plain or anged, the channel-shaped member having unequal legs and disposed Vwith its web parallel to the car side and its flanges directed outwardly and the plate member lying in the plane of the car side and welded to the edge of the shorter leg and to the longer leg in spaced relationship to the edge thereof. The channel member of the welded door post may be replaced by avilanged plate member whose flanges lie parallel to the car side'. vIn the latter construction the first mentioned plate member of the door is welded to the latter plate member as described above.

It will be apparent that numerous changes and modifications in the details of the invention will be clear to those skilled in the art. It is intended, therefore, that all such modifications and changes be comprehended Within this invention which is to be limited only by the scope of the claims appended hereto.
