10 Claims. (CL MI5-369) 'Ihe loading lof sewer pipe, building tile and similar objects for railway shipment is a matter which presents many dimculties. With bell-end sewer pipe, for instance, the loss due to breakage in transit has been enormous, because of the fragile character oi' the material, the tendency of the bells to take up the weight of the load, and the difficulty of preventing the sections of pipe from pounding against each otherwhen jarred.

The purpose of this invention is to provide an improved method of loading which will result in less breakage, is easy to practice, and canbe employed at small cost.

In order that the invention may be readily understood, two different embodiments of the same are presented herein by way of exemplication, but itv will of course be appreciated that the invention is susceptible of embodiment in other forms coming equally within the scope of the appended claims. In the accompanying drawings:

Fig. .1 is a horizontal section through one end, of an ordinary box car, showing a load of sewer pipe madeup in accordance with the invention;

Fig. 2 is a vertical longitudinal section through `the same end of the car, taken on the line 2-2 o f Fig. 1, showing one of the units of the load in side elevation;

Fig. 3 is a vertical transverse section through i the car, taken on the line 3-3 of Fig. 2, showing the load in end elevation and Figs. 4 to 6 inclusive are views which correspond respectively to Figs. 1 to 3 inclusive but which show a modified load structure made up in accordance with the invention.

The load shown in Figs. 1 to 3 inclusive is a load of ibell-end-sewer pipe. Only half of the load is shown, since the other half, which is lo-` cated in the other end of the car I0, is the same. 'I'he half load consists of three separate units II, I2 and I3. In each of the units, the individual sections I4 of pipe are stacked on their sides in pyramid form with the bottom row resting on twospaced parallel supporting members I5. The sections I4 are placed with their axes crosswise of the car and are arranged parallel with each .of the sections in the bottom row may be separated from each other, if desired, by cross cleats I8 which are secured to the members I5. The sections at the ends of the bottom row are held against 'outward movement by relatively heavy cross members I9 which are secured to the members I5. The second row contains one less section of pipe than the bottom row, and the sections in the second row are placed on the bottom row with the spigot ends in the second row resting on the bell-ends in the'bottom row and with the bellends in the second row resting on the spigot ends in the bottom row. The same spigot-to-bell ar- 10 rangement is followed in building up the remaining rows, each added row containing one less section of pipe than the underlying row to permit nesting of the sections and permit' of a pyramid formation. 2

After all of the sections of pipe in the unit have been stacked up in the manner described,- two or more metallic bands of either round wire or at strap are placed under tension about the unit in laterally spaced vertical planes disposed 20.

lengthwise of the rows and crosswise of the see-g tions. 'Ihe bands 20,are also preferably so positioned as to embrace the cross members I9 at the ends of the unit. After all of the units II, I2 and I3 have been made up, theyare ready for 25 shipment. 'I'he units are preferably separated from each other by the insertion therebetween of loose partitions 2|. When the car I0 receives a severe shock or jar during transit, each 'of the sled-like load units 30 will shift bodily along the floor of the car for a short distance, thereby preventing any substantial localization in the load of the stresses caused by the impact. By employing this method of loading, a. considerablesaving in breakage can be effected.

As an alternative arrangement, the bell-ends I6 of the sections of pipfinstead of being placed on the spigot ends II of the underlying sections, may be so arranged as to project laterally beyond 40 the spigot ends, thereby making va more compact but slightly wider stack. s

The modied load shown in Figs. 4 to 6 inclusive diifers from that' shown in Figs. 1 to 3 inclusive in that each of the several load units 22 45 is of rectangular, as distinguished from pyramid, form, resulting in a shorter unit. Because of the relatively short lengths of the rectangular` units,v two longitudinally spaced groups of the units may be placed withoutinterference with each other in each end of the car.

The sections of pipe in each of the units 22 are stacked on their sides crosswise of the car in superposed rows extending longitudinally of the car. The bottom row rests upon twovspaced parallel supporting members 23, and the end sections in all of the rows are held in place by two upright supporting frames 24, which frames are secured at their lower ends to the ends of the members23. After all of the sections have been placed in the stack, the latter is bound into a solid unit by two or more tensioned bands 25. During the stacking operation, and before the application of the bands, the frames 24 may be temporarily held upright by any suitable bracing means. The upper ends of the frames 24 .are preferably connected together at opposite sides of the unit by strips 26 which assist in preventing outward movement of such ends and also help to keep the sections in the uppermost row in line.

The sled-type load unit forming the subject matter of this invention is not onlyl of value because it reduces breakage in transit but also because it permits of improved loading and unloading. 'I'he units may be made up outside of the car in manageable sizes and then placed in the car by means of a crane, truck or other lifting and conveying device. Upon arrival at destination, the units may be removed from the car in the same way. By following this procedure, very little of the work involved in making up the load need be done in the car, and, as a result, the time required for actually loading the car is reduced to a minimum.
