25 Claims.

This invention relates generally to multiple unit tank cars and more particularly to a car adapted to carry a large number of tanks of relatively small diameter and ci considerable length such as are customarily used for the transporta tion and storage of fluids especially gases such as helium although it will oi course be understood that the arrangement of parts and principles employed herein are applicable to tanks of va rious sizes, shapes and numbers.

One object of the invention is to provide an improved arrangement for supporting the tanks so that they vare effectively held against shifting and in one specific aspect of the invention this is accomplished by interlocking the tanks with each other and anchoring the interlocked tanks to the car frame.

A further object is to provide an arrangement and construction of parts vwhereby the tanks may be easily loaded and unloaded without interference from the interlocking elements or undue delay being caused by the anchoring means.

A more specic object of the invention is to provide interlocking tank elements in the form of rings or bands shrunk or otherwise secured to the tanks preferably at their intermediate portion although under certain conditions the interlocking elements could be placed at any point or points along the length of the tanks. While bands are specifically shown as completely encircling the tanks it will of 'course be understood that the elements may extend only partially around the tanks and thus be in the form of lugs or projections which could be welded or otherwise secured to the tanks.

Another object is to provide anchoring means arranged so as not only to facilitate loading and unloading of the tanks but also to effectively distribute the anchoring stresses to the car frame.

Other objects and advantages will be more apparent to those skilled in the art from the following description of the accompanying drawings in which:

Fig. 1 is a vertical longitudinal section through one end Vof the car and beyond the point of anchorage.

Fig. 2 is a sectionat the point of anchorage, taken on line 2 2 of Fig. 3, the right end of 5o view being shown in elevation. K

Fig. 3 is a transverse section taken on the line 3 3 of Fig. 5 and showing the tanks in end elevation at the right and at the left showing the tanks and their anchoring bands.

55 Fig. 4 is a transverse section taken on the line (Cl. 10S-360) 5 5 of Fig. 2 and showing a modified orrn oi' tank saddles, used adjacent the anchorage point.

Fig. 5 is a horizontal section of one quarter ci the car, the section being taken above the second tier of tanks with a portion oi all of the 5 tanks omitted to show details of the underframe and superstructure.

Fig. 6 is an enlarged elevation of a portion of one of the vertical brace gussets showing the rectangular openings therein for the reception 10 of lugs formed on the wedging elements, said lugs being shown in section taken on the line 5 6 of Fig. 7.

Fig. 7 is a horizontal section taken on line 7 1 of Fig. 6. l5

Figs. 8 and 9 are vertical transverse sections taken on line i-S and 9 8 of Fig. 6.

In the specific embodiments of the invention, which are shown herein merely for purposes of illustration, there is provided a car whose under- 20 frame includes a center sill l, end sills 2 and usual body bolsters 3 connected by side sills Crossbearers 5 are provided at suitable points, two of which are shown in Fig. 2 to be relatively close together near the center of the car for the 25 purpose of supporting anchorage means including vertical brace gussets t5 and l. These gussets are wide at their base and taper to a narrower width at their top near the upper horizontal row of tanks 8. In the car as shown, 48 30 tanks are provided and to insure suitable anchorage for all of the tanks two brace gussets such as 6 and l are each disposed to` one side of the center sill. The inner brace 6 is secured between a longitudinal underfrarne channel 35 member 9 and a longitudinal bracket l0, this bracket in turn being riveted to the web of the adjacent channel of the center sill. Channel 9 and bracket l0 are also secured to the underside of the top cover plate il of the cross- 40 bearers. From this construction it is seen that any stresses set up in the anchorage gusset will Y be distributed through the center sill, crossbearers and side sills thus avoiding undue localization of stresses which would result in abnor- 45 mal torsional eiects and Wear and tear on the car frame in addition to permitting possible weaving of the tanks.

The outer brace gusset 'l is held in position by extending down between and being secured to two channels l2 which are connected to the upper and lower plates ll and E3 of each of the two central orossbearers. To provide as few different parts as possible it will be noted that channels 9 and l2 are the same.

A brace ld is inserted in each of the crossbearers and secured to the top and lower plates thereof.

From the arrangement so far described it is seen that each brace gusset has a vertical row of tanks 8 on each side thereof. The tanks are locked or held against shifting by providing a band, ange or other suitable projection I5, Figs. 7-9 on the outside of the tanks near the center thereof. In the case of a band being used it is preferable to shrink on the same. 'I'he vertical rows of tanks are disposed with the bands in vertical alinement while in the transverse rows the bands are staggered so as to overlap one another. The outer single vertical row of tanks A are held solely by wedges engaging these bands and tovbe presently described while similar wedges are also used for the inner rows of tanks, these wedges being carried by the gussets.

The bolsters are provided with a plurality of spaced saddles I I adapted each to receive one of the lower tanks as shown clearly in Fig. 3. v

Secured to the crossbearers are saddle members I8 disposed between adjacent tanks and having oppositely arranged seating surfaces for engaging said adjacent tanks, also as shown in Fig. 3. Adjacent the side sills 4, half saddles I9 are provided for the outer tanks while side stakes 20 in the form of channels are secured to the side sills to support said outer row.

To load the car the lower row of tanks will be placed rst on the underframe saddles with the bands of the inner pairs of tanks longitudinally staggered and in overlapping abutting engagement with each other as previously described. The tanks will then be secured or anchored in position by the provision of a'wedging device generally indicated at 2| Vas shown more particularly in Figs. 6 9. This device comprises longitudinal wedge plates 22 riveted to each other on opposite sides of the brace gussets 6 and 'I respectively, the lower edges of these plates being beveled as at 23. A series of square openings 24 specifically four in number as shown in Fig. 6 are provided in the brace gusset just below the plates 22 while bolt holes 26 are also provided in the gusset. A cooperating wedging element or block generally indicated at 21 is Vof substantially elongated formation having a pair of

lugs

28 and 29 projecting inwardly through a pair of the openings 24 and engaging the edges thereof to prevent longitudinal shifting of the Wedge or anchor block. These blocks are also provided with wedge surfaces cooperating With the wedge surfaces 23. 'I'he outer face of each wedge is provided with ears 30 adapted to be disposed on each side of the tank band I5. It willbe noted that there are two ofV the wedge blocks, one on each side of the gusset, and these are held in position by a pair of bolts 3|. While the Wedge blocksV are identical still the pair of

lugs

28 and 29 on each block will be in staggered relation when the respective blocks are placed or disposed on opposite sides of the gusset, this being due to the

lugs

23 and 29 being non- Ysymmetrical with respect to the transverse center of the blocks. The same is also true ofthe band engaging lugs 30. Due to the circular cross section of the tanks it is seen that ample space is provided, between the adjacent quadrants of any four tanks, in which the wedging device may be disposed. The outer lower tank is secured in position by a similar wedging arrangement except that only one wedge block and plate such as 22-21 is secured to the side stakes 20 and this wedge block has no

lugs

28 or 29. With the lowermost transverse row of tanks in position the next Vrow will then be placed with their bands in vertical alinement with the bands of the lower tanks. This row will then be clamped in position and this procedure continues until all of the tanks have been placed in position. After each transverse row of tanks is positioned saddles 32 are placed upon the tanks and tie rods 33 will extend from each side stake to the other and through suitable openings in the saddles. Also, if desired, Vtie rods 34 may be used to connect certain of the side stakes while supplemental saddles 34' may be used withy the tie rods 34 and disposed between the adjacent quadrants of the tank shells.

Means are provided at the neck ends of the tanks as an additional supporting means and for the purpose of providing against longitudinal shifting, said means comprising a bulkhead 35 formed with openings into which the necks 36 of the tanks extend as shown in Fig. l, the bulkhead being supported by a floor 39 and being detachably secured in position by bolts 37 connected to the floor and by bolts 38 connected to angles 48 arranged adjacent the ends of the car and connected to the side sills 4 and to side plates 4I. For connecting the angles 48 to the Yside plates, angle brackets 49 are secured to the side plates as clearly shown in Fig. l.

Disposed in front of the bulkheads 35 is a suitable framework providing hinged

doors

42 and 43 at one end of the car supported respectively on a verticaly angle member 44 and a channel member 45, but at the opposite end of the car however, due to the application of the usual hand brake (not shown), the doors 43 are omitted and the ends permanently closed by plates riveted to the channels 45 and to a vertical member, at the transverse center of car, such as a Z-bar or any other section desired. The space between the bulkhead 35 and the doors provides room for any suitable and desirable valve mechanism or control equipment for the tanks.

To suitably cover the tanks and yet to permit 45 easy removal thereof by being vertically lifted from the car there is provided a roof [i9 secured to one leg of the longitudinal Z-bar side plates 5I, the other leg of which is removably secured as by bolts 50 to the side stakes 20. i9 obviously serves as a tie member between the side stakes on opposite sides of the car. Ladders 46 are provided at each end of the car to serve as an approach to a suitable running board 5l which is mounted on the top of the roof and is removable bodily therewith. While it is preferable to have a closed Ytype underframe as shown in Figs. Sand 5 wherein the floor 39 entirely closes the same, still if desired, under certain conditions an open type underframe may be employed wherein all of the other remaining elements are the same as shown in Fig. 3.
