UlstE FOR RAILWAY Germany, assignor to (l Curt Stcdefeld, both of 1934, Serial No. 101,311
In Germany January 17, 19 3 18 Claims.
The invention relates to skeleton structures for railway cars, and more particularly for railway cars intended for very high speeds, and describes a novel three-dimensional latticework for such cars. Similar skeleton structures are described and claimed in my prior application Ser. No. 660,283, filed March 10, 1933, on which Patent No. 2,040,257 was granted May 12, 1936. The three-dimensional lattlcework of the cars described in said application comprises low main girders disposed in the side walls below the bottom edge of the window surface which extends without interruption over the whole length of the car. The ends of these low main girders are provided with rigid fiexure resistant or flexure-proof superstructures between which is fixed a moment resisting or buckling-proof roof or a false bottom below or both simultaneously. The inside and the outside linings enclose the main 20 girders. Stiff cross walls disposed at the" ends of this skeleton structure complete this latticework in space. These types of skeleton-are particularly advantageous for railway vehicles which can be built without regard being paid to any maximum moving dimensions, special restrictions etc.
When however in the design of modern vehicles, particularly. of those intended for high speeds, stream-line shapes, low-weight construc- 30 tions, low position of center of gravity, etc. are to be taken into consideration, while there are fulfilled all conditions imposed by existing railway installations, administrative prescriptions, dispositions of the platforms, habits of the pas- 35 sengers, etc., it is advantageous not to dispose the low main girders within the side walls. In order to reduce the air resistance, the false bottom of the vehicle is arranged close to the railheads and the cross section restricted to the indispensable amount. When however the floor of the car is left at the level of the platform top, the doors will be placed in recesses in the side wall of the car, these recesses extending from the car floor deeply into the roof. In this way the 45 main girder would be completely out asunder in the side wall. When the girders are located in the planes of the side walls, other design requirements render it impossible to offset the main 50 girder downwards.
It is an object of the present invention to obviate these several difficulties by the low main girders being disposed between the car floor and the false bottom of the'vehicle and at the same 55 time out of the plane of the side walls. The ends of the girders carry rigid superstructures which are so connected to the girders as to resist bending, and bars capable of resisting bending and buckling extend between the superstructures. These bars may be structural members of the roof or connected with one another by web members or roof sheets so as to form the upper horizontal bracing of the skeleton of the car. This carrying skeleton is completed by shells or shelllike bodies which below are fastened to the low main girders and on top to the said flexureand buckling-proof roof bars so as to form the car body proper. The said shells consist of a framing comprising stiff cross frames and longitudinal sections and are lined with sheet metal or another suitable lining material, the cross framings securing the roof bars against buckling, which bars are inserted between the end superstructures connected in a flexure-proof way. On account of the low weight aimed at,the side shells are made of the thinnest sheets and sections available which in the case of sensible deformations of the main girders are liable to buckle and f crease.
It is a further object of the present invention 25 to obviate this inconvenience by the length of the lateral shells being limited and the number of the said shells arranged in series being determined in accordance with the degree of deformation likely to arise. In some instances this subdivision of the shells in a lengthwise direction will not yet be suflicient so that deformations should be possible within the shell unit concerned without resulting in creasing or buckling.1 To this end the lining sheets are fastened at one edge only, preferably on through sections, the other edges of the lining being left movable, while the movable joints are sealed in a suitable manner against the penetration of rain, dirt, etc.
The invention is illustrated diagrammatically and by way of-example on the accompanying drawings on which Figs. 1-3 show the principle of the invention in perspective views,
Figs. 4 and 5 show lateral shells,

These superstructures, in this instance, are frames 23, 21, 23 and 29, stiffened against bending and which may, for example, enclose vestibules. Between the top ends of the superstructures 22, 23, 24 and 25 is inserted the roof strip 30, the floor 3i acting as the lower horizontal bracing while the said roof strip is'the upper horizontal bracing. By lateral shells, which may extend over the whole length of the car (Fig. 1) or comprise a plurality.
of short ones behind one another (Fig. 3) this car skeleton is completed to the car body proper. According to the purpose aimed at, these shells 1 and 3 show lateral shells suited for passenger cars, in which 32 is the passenger room with a continuous window surface '33, while 34 and 33 are for example auxiliary rooms, such as cloak room, lavatory, etc. 36 and 31 may be vestibules or the like.

In order to be as light'as possible thelateral shells (Figs. 1,3, 4 and 5); are madeof the thin-- nest sheets and sections'available. Structural members vofthis class .tend to bulging, buckling, and creasing in the-case of deformations exceed ing a definite limit. Asthe lateral shells are.

The sections 43 and ill, by which the lateral shells are connected to the skeleton, must partake of the contractions and dilations: of the members of the skeleton to which theyare fastened, whereas the sections 3i and 32 are not subject to such The side surface of these shells is' formed by the posts 33 only which are associated stance and 66 are the side, walls.
I bracing, the said 7 case it is readily freedom of motion,
and 43 are the lateral contractions and dilations since the changes of length are compensated by the particular construction of the cross frames 41 and 43. The lining sheets 34 are at the sections BI and 32 rigidly fastened to the framing of the lateral shells without being subject to deformations while the other edges 53 of the sheet are left movable.
Fig. '7 shows a perspective view of a section of such a movable arrangement of the lining sheet as taken at a joint formed by the lining plates and the cross beam 43, Fig. 6, which joint is sealed against the penetration of atmospheric matter. 56 and 31 are the web plates of the cross frame 48 (Fig. 6) which are connected with each other by the sections 53 and '53. The latter are so shaped that the web plates 33 and I! are allowed to springingly move towards or from each other. So the sections 3i and 32 (Fig. 6) are left without sensible stress or deformation. To these sections are fastened the lining sheets 33, which can have different shapes and appearances. Figs.

On account of its ribbed shape and sunlclent softness therubber 32 ensures tightness and satisfactory mobility. j The sheet strip 33 is fastened from the inside by means of bolts 34.
5 Figs. 8and 10 show car skeletons'constructed on the same inventive idea, Fig. 8 representing a design suited for compartment cars. In this inagain the low girders dis- 31 and out of the plane of At their ends they carry the superstructur'es 33,33, 13 and II connected therewith in a' moment resisting wayand engaging between them the horizontal bars 12 and 13. By

To this, skeleton. are, for example, applied a plurality of shells, each of the length of one 'compartmentfwhich with their lateral solid-web frames at the same time form thepartitions of the compartments. For better clearness only one of these shells (Fig. 9) is shown as being separated'from the skeleton. The other shells are represented inthe drawings by their sidewalls '14 only. The superstructures 33, 33, I3 and H preferably enclose the auxiliary rooms. Fig. 10 shows a car skeleton of thesolid-web type. The superstructures 13,19, 30 and 3| disposed at the ends are-closed frames, between which the roof strip of the main girders 16 and I1 32 is inserted. The solid-web construction of the main girder affords particular advantages for the construction of the side shells. -'In this possible to choose the length of the .shells to be connected-tothe said girder,
without regard toa bayhdivision of'the main girder, which fact can be of great advantage, for example, in the case of cars having compartments of different lengths according to the particular classes. Fig. 11 shows a shell which is suited for highcapacity cars and attached to the thin girder "and the roof strip 32 by means of its moment-resisting cross frame 35. In the drawings the other lateral shells. are diagrammatically represented by their cross frames laterally connected to the skeleton while the longitudinal sections and lining sheets are omitted.
For certain types of cars it is advantageous to v dispose the girders as close to the side walls amuse g as possible. Riga-12 and13 show constructions of this-type, in which, 04 and 05 are the main girders. 'I'he superstructures 06, ll, and 80 against which'bearsthebuckling-proof roof strip 90,-are inclined towards the center line while beingduly supported in order that full freedom is left for the design of the lateral shells. In Fig. 13 the main girders SI and 92 are in an inclined position so that the clearance gage restricted in-this place is better utilized, The inclined superstructures 93, 04, 05 and 00, which are stiifened against flexure, are at 01 and I0 connectedwith each other, and a buckling-proof compressionalbar 99 is inserted at these points. The closing of the passenger room as effected by means of shells is diagrammatically'represented by the supporting frames I00. For better clearness the longitudinal bearers, the horizontal bracing and the sheetlining are omitted in the drawings.
Fig. 14 shows a further embodiment of the inventive idea. The low main girder IN is disposed below the floor and the superstructures I02, I00, I0| and-I05 thereto connected in a flexure-proof way embrace between them the wings or projections I01, I00, I09 and H0 of the roof portion I06. The rigid supporting frames III diagrammatically represent the construction of the clothing arrangement.
Fig. 15 shows how the skeleton of a high-speed vehicle is built up in accordance with the present invention and it represents the front end' of a modern stream-line high-speed car. The stream-line is diagrammatically shown by the dotted contour II2, while H3 is the running and driving gear and Ill the engine room. The
main girders H6 and III disposed below the floor I I5 of the passenger room are deflected to extend upwards abovethe running gear and downwards again below the engine room: In suitable places are connected the flexure resisting superstructures H8 and 9, with which is connected the buckling-resistant roof strip I20. To the end of the cantilever portion of the main girders Iii and Ill respectively projecting beyond the running gear H3, there are connected superstructures I2I and I22 which are likewise stiffened against deforming moments. Between these superstructures and those designated by H0 and H9 is disposed a roof portion I23 subject to tensile stress and which has the same relieving effect on the cantilever portion as the roof portion I20 on the central part of the said main girders. The outside contour of the passenger room is again diagrammatically shown by the stiff frames I24. For better cleamess the outside lining is omitted in the drawings.
In some instances it is desirable to bring the superstructures connected to the main girders, out of the plane of the said main girders, for example, in order to allow fora more convenient disposition of the auxiliary rooms. Fig. 16 shows such an arrangement. By I25 and I20 are again designated the main girders which are disposed below the floor I21 and in close proximity to the wheels I28 of the running gear. On both sides of the narrow passage I29, which may lead to another car, there are arranged the auxiliary rooms I30 and I3I which may be used as cloak' room, lavatory, service compartment, kitchen etc. The superstructures I32 and I32 being disposed in the plane of the main'girders I25 and I20 would result in rather narrow auxiliary rooms or at least interfere with an advantageous disposi- 75 tion thereof. This inconvenience is obviated when the superstructures I32 and III are brought out of the plane of the main girders, for example, by being shifted towards the center line of the car. Every single memberof the said superstructures must then be constructed as a flexure-resistant frame bar.. When symmetry is admissible, closed frames I" could be used to advantage. The rigid frames. I05 diagrammaticaly represent the lateral sheels attached to the skeleton, and
the chain-dotted lines I30 and Ill show stiffening members between'the two buckling-resistant roof members I which are connected to the superstructures I02 and I32.
