Johansson, Cleveland, Ohio, assignor to The Youngstown Steel Door Company, Cleveland, Ohio, a corporation of Ohio Original No. 2,602,405, dated July 8, 1952, Serial No. 105,579, July 19, 1949. Application for reissue July 8, 1952, Serial No. 297,791

11 Claims. (Cl. 105-409) Matter enclosed in heavy brackets appears in the original patent but forms no part of this reissue specification;

'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 as in automobile box cars and some box cars, are reinforced by means of 15" 40:9: channels whose upper flanges are riveted to the horizontal legs of the side sills. The reinforcing channels extend across the door openings and for a sufficient dis- The vertical legs or the 3 legs are disposed vertically.

In this construction a further reinforcement is provided at and adjacent to each door post 'by means of a gusset formed from a flflplate secured to the door post by seven rivets in single shear arranged in a vertical row and to the ver 'tical 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. Andthe rivets securing the reinforcing channels to the horizontal legs of the side sills work loose with consequent development of fractures in 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 difiiculties of present day construction of box cars.

A further object is to provide a construction for house cars which shall increase the strength of the side sill structure at the door openin adjacent to the door posts.

A further object is to provide a construction for house-cars which shall increase the strength of the connection of the side sill structure to the carside construction at the "door posts.

A further object is to provide a construction for house cars which shall secure aninerease 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 provide a 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 house cars which shall obtain a substantial increase in the moment of inertia and section modulus of the construction.

A further object is to provide a construction for house cars which shall utilize gussets to realize a substantial increase in the strength 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 cars adjacent to the door posts.

Other objects of the invention will become clear as the description thereof proceeds.

In the drawings forming part of this specification:

line 34- 1 Fig. 7 is an eleoaiional view ofthe reverse side I of Fig. 1.

In the drawings a preferred embodiment of the invention is shown at the lower forward'portion of a door opening Ill formed in the side II 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, door opening. Since the construction embodying the-invention 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 However, this construction The carside ll embodies a front door post 12 which comprises a Z-shaped member so arranged that its web I3 extends longitudinally and substantially in the plane of the carside, its flange [4 extending outwardly and its flange l5 extending inwardly. The door post illustrated also comprises an angle member I6 having an inwardly extending leg I1 secured as by means of rivets l8 to the flange I5 of the Z-shaped member l2 and a longitudinally extending leg l9 which is in alinement with the web I3.

The carside also embodies an angle side sill having a vertical upstanding flange 2i and a horizontal inwardly extending flange 22. Within the door opening the upstanding flange 2| is cut "down inheightas 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 sufqficient'distance beyond each side of the door opening 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 2,9 formspart of the carside and is secured by means of riveting to the web 13 of the door post 12 and to the upstanding leg 2| of theside 58111.

"In orderto adequately reinforce the construction hereinabove d scribed at a jacent t thedoor opening, the instant invention utilizes inner and outer gusset members 30 and 3 I. The inner usset member 39 is' ecured o the inner dace of'the web l3as by means of rivets 32 and to' he inner face of the'lon i udinally extendin leg 19 asbymeans of 11ivets33- The inner u set member 30 isseoured to the inner fa e of th upstandin fl n e 2| of th side ill y m ans of a do ble ow of rivets 5- The lower margin of theinnergusset member is provided with an inwardly extendin hor z l n e "w ich is secu d a by me n of rivets :36 to he ho ontal flan es :22 and .21 of the side sill and side sill reinforcement, respecii s moreoiearly shown in Figs 1 and 5 f the dr ,wi es. the ;h rizontal lange .5 of th e as; set m mb r is ext nd d into th d or op n-i sand w thin the enin t i n r usset member is cut down in height as indic ated at :31 so it lies s hstoh i i iin e up er plane of the car floor. (See Fig. 4).

The outer gusset mem er S is se ured y means of the

rivets

32 and 33 to the outer face Zofwthe web 13 and leg is, respectively, and to the inner gusset member 30 thereby placihgthe "'rivlets 32 and 3:3 in double shear. The outer gusset member 3| is also secured by means of the rivets '534 tothe outerface of the upstanding flange 2| of the side sill. Thus the rivets 34 which also secure the inner gusset member 30 to the 11pstanding flange 2| of the side sill are placed in double "shear.

*Theouter gusset member '3! beyond the door openingis extended downwardly as indicated at -38 andis secured-as by means of'riye'ts 3 9 to the-outer face of'thewebzli of the sidesi-ll reinforcement.

The outer gussetmember is also extended along the door opening'l II 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-.5]. The latter extending portion of the outer gusset -member-terminat'es substantially-in the upper 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 I.

By virtue of the invention the moment of inertia and the section modulus of the carside construction has been substantially There has been obtained also a substantial increase in the v hickness 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 '{ri-vets are placed in double shear.

To avoid conflict between the inwardly extending flange l5 and leg I! of the door post and the inner gusset member 30, the flange l5 and leg I"! are terminated above the gusset member as indicated at 43 and 4.4. The web l3 and the iongitudinal leg l9 are continuous, however, and are extended so as to terminate above and adjacent to the upper edge-of the upstanding leg 2| or the 'side'sill as indicated at 45 and 46, While the web I3 is coped as indicated at 41 to conform to :the cope 48 in the leg 2!, the outwardly extending flange M of the Z-shapedmember of the door post is extended downwardly below the door opening as indicated at .49 and is preferably welded'to the outer gusset member 3|.

To compensate for the loss of strength resulting from the removal of the inwardly extending flange I5 and leg I1, a plate member 50 is'disposed between and secured as by means of rivets 5| to the inwardly extending flange l5 and leg 11 as shown more clearly in'Figs, 1 and 3 of the drawings. For this purpose the angle member It is oilset as indicated at 52. The reinforcing plate member 50 is extended downwardly to the inwardly xtendin flan .35 of the n e 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 avoidins con lict between this e be d h r et sion from the vertical rivets which secure the horizontal flanges of the side sill and side sill reinforcement together. The stress to which these rivets 'are subjected is essentially a shear stress whose unit valu 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'no't limited to thetype of door post i-llustrated in the drawings but is capable of use with the various types of door posts employed in house carconstructio'n. For example, the door posts "may be formed of the Z-shapedmember alone without the separate angle member, or of a w-shaped member, or the substantiallychannelsshap'ed A. A. 'Rytype door post may be used. Again, any of the known types of Welded door posts may be utilized, such as the door post formedof .a channel-shaped member and a plate member plain or flanged, the channel-shaped member having unequal legs and disposed with its web parallel to the car side and-its'fiangs increased.

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 a flanged plate member whose flanges lie parallel to the car side. In the latter construction the first mentioned plate member of the door is welded to the latter plate member as described above.
