Application filed March 1591926. Serial No. 94,742.
Our invention relates to tank cars suitable for the transportation of fluids under high pressures, and it has for an object to provide apparatus of this character wherein the tanks shall extend for the full/lengthv of the car structure and be supported in such a manner that the tanks shall not have stresses imposed thereon due to deformation of the car structure in service.
In order that gases or liquids under high pressure may, be transported by railwa it is-desirable that the tanks shall be made as large as possible, within reason, in order that the tanks shall each have a reasonably large capacity and in order to simplify the tank car construction. In view of the fact that very high pressures may be imposed on tanks of this character, they are made of single pieces of forged steel in order to secure a receptacle, considering the volume, which is strong enough to resist hlgh pressures with safety. However, 1n new of the fact that a railway car deforms or weaves more or less 1n servlce, it 1s necessary that such a mode of.
support shall be used as will not impose upon the tanks stresses due to weaving or deformation of the car, otherwise such weaving or deformation might result in the application of concentrated stresses to the tanks with possible rupturing of the latter. To this end, we'provide tanks of the character referred to which extend for. the full length of the car construction and which have, in effect, twopoint supports, each tank having its end portions supported substantially in the planes of the body bolsters. With such a. construction, it will be apparent that the tanks may be held in place against longitudinal movement with respect to a car while at the same time relative movements of different parts of the car may take place withoutresulting in the setting up of stresses, due thereto, in the tanks. A further object of our invention is to provide a tank car construction of the character referred to wherein a pair of lower tanks shall extend longitudinally of 'the car and be supported on the body bolsters and an upper tank shall extend longitudinally of the car and be supported by and spaced from the lower tanks at the end portions-thereof, the vertical plane of the longitudinal axis of the upper tank being disposed substantially midwa between the vertical planes of the longitudinal axes of the ments of the tanks relatively to the bolsters be resisted.
A further'object of our invention is to 4 provide a tank car arrangement having tanks supported on body bolsters together w1th anchorage means cooperating .with iny tel-mediate points of the tanks, the anchorage economically, with a minimum of handling,
means being of such a character as to permit of relative movements between the tanks and the car construction in service, whileafl'ording support for the tanks and restricting lateral movements of the tanks with nection with the accompanying drawings,
forming a part of this application, in which:

Fig. 2 is a top plan viewof the apparatus shown in Fig. 1;
Fig. 3 is a vertical longitudinal sectional view of the apparatus shown in Fig. 1;
F ig. 4 is a fragmentary plan view, with parts shown in section, of the center sill and bolster construction;

. Fig.- 6 is a fragmentary detail view showing the support for the intermediate anchorage device;
Fig. 7 is a detail view showing the relation between one of the bolsters and one of the tanks; Fig. 8 is an end elevation of the apparatus" shown in Figs. 1 and 2; and,
Fig. 9 is a sectional view taken along the line-IX-IX of Fig. 3 and Viewed in the direction of the arrows- In- Figs. 1 and 5, we show a central sill surface, so as to correspond with the pe- .riphery of the tanks 15. Said'tanks are provided with peripheral shoulders '16 spaced in excess of the width of the body bolster 12 so as to limit the longitudinal free movement of the tanks (see Fig. 7).
We also show a single tank body 17, forming the upper tank tier, two cradle castings 18, a link 19 connecting the castings at their inner extremities and tie rods 20 connecting them at their outer extremities with the body bolster 12. The cradle castings 18 are designed so as to provide brackets for'the running boards 21 and are furthermore concaved so as to conform with the periphery of both the upper and the lower tank bodies. Straps 22 pass over the upper tank body 17 and are anchored to the cradle castings. One of the straps 22 is provided with a bracket 23 to support a hand rail 24. The tank body 17 is provided with peripheral shoulders or flanges 25 in a manner similar to the shoulders or flanges 16 .on the lower tank bodies 15, the flanges or shoulders 16 being disposed laterally of the sides of the body bolster 12 and the flanges or shoulders 16 and 25 being disposed laterally of the sides of the saddles, whereby longitudinal movements of the tanks relatively "to the car structure are limited.
Referring to Figs. 1, 3, 6 and 9,.-'we show means for. bracingthe tanks withrespect to the center sill at convenient points between the body bolsters 12. At such points, an anchorage bracket 30 is riveted to the center sill 10, a cross beam 31 is interposed between the upper vand lower tanks, a spacing yoke 32 is placed adjacent to the cross beam 31 and a pair of links 33 are inserted to connect the bracket 30 with the cross beam 31 and the spacing yoke 32, respectively. The cross beam is provided with an angle 34 to support the running boards 21. A single strap 35 passes over the upper tank body 17 and is anchored at each end to the running board structure, the strap preferably being provided with a bracket 36 for the hand rail 24.
The anchorage bracket 30 comprises two projections, extending towards-the axes of the two lower-tanks and-having surfaces 37 shaped to conform to the tanks, and atransverse rib 38 drilled for attachment of the links 33, as shown in Figs. 6 and 9.
The cross beam 31 and the spacing yoke 32 have their lower surfaces concaved to bear on the lower tanks 15 while their upper surtaces are shaped to elear'the upper tanks 17, The links are intended to have some initial tension when the structure is assentbled so that the lower tanks are clamped between the surfaces 37 of the bracket 30 and the lower surfaces of the cross beam 31 and of. the yoke 32. i
From the foregoing, it will be apparent that we have devised a tank car constructlon which is characterized by a center sill with bolster structures connected and firmly braced to the end portions of thesill. The tanks 16 and 17 extend for substantially the full length of the car, the lower tier of tanks being supported by the bolsters 12 while the upper tier, shown as consisting of a single tank, rests on the lower tanks. As
already pointed out, the arrangement of flanges on the lower tanks 15 laterally of the sides of the bolster seats limits movements of the lower tanks longitudinally of the car with respect to the bolsters. The flanges 25 on the upper tank are disposed laterally of the cradle members 18, the latter members also fitting between the flanges 16 on the lower tanks. Resistance tq longitudinal movement of the tanks is essentially frictional, being supported by straps 20 and 22; and, in View of the character of material and length of such straps, large hold-down forces may be exerted, while preserving qualities of yielding, largely due to possible elongation of the straps, so that, in case of extreme stress, the anchorage. devices are not broken. Anchorage devices of this character are peculiarly suitable for large tanks of the type herein referred to for the reason that stresses are distributed and not concentrated and for the further reason that no special modification of the tank structure, other than-the ribs or flanges is necessary. It will, therefore, be apparent that we have devised a tank car construction in which each tank has a two-point support, the lower tanks being supported by the bolsters and the upper tank being supported by and spaced from the lower tanks. Assuming the car structure to weave or to deform in service, any such deforming movements of the car structure may take place without imposing a dditional stresses on the tanks; and, in view of the fact that these tanks are likely to be filled with fluids under high pressures, it is important that the tanks are relieved from external stresses as far as possible.
In view of'the length of the tanks and forces to which they would be subjected in service, it is desirable to provide some form of intermediate support or anchorage. At the same time, any such supporting means or anchorage arrangement should permit of relative movements taking place between the car structure and the tanks so that the tanks may readily accommodate themselves to different conditions of deformation of the car structure, or possibly of the tanks, without having stresses imposed on the tanks. -To this end, it will be seen that the links 33 may pivot with respect to the bracket 30 and the lower tanks. This articulated anchorage arrangement, therefore, permits the lower tanks to assume natural positions without being resisted by rigid anchorage structure, while, at the same time, anchorage and support for the lower tanks is secured to the best advantage. To the end of holding the upper tank in place with respect to the center sill 10, the anchorage arrangement is provided with a strap 35 secured in place with respect to the saddle beam 31 and extending over the upper tank 17. The saddle members 31 and 32 rest on the lower tanks but are spaced from the upper tank. Therefore, it will be seen that the anchorage 'ar-.
rangement maintains the tank assembly in position with respect to the center sill 10 while permitting movements of accommodation to, take place without subjecting the tanks to external stresses due to the anchorage,
While Wehave shown our invention in but one form, it will be obvious to those skilled in the art that it is not so'limited, but is sus ceptible of various other changes and modifications without departing from the spirit thereof, and we desire, therefore, that'only such limitations shall be placed thereupon as are imposed by the priorart or: as are specifically set forth in the appended claims.
