'7 Claims. 1

This invention relates to an improved palleting arrangement and more specifically to an improved means for positioning article-containing pallets on a transport device such as a truck or railroad car. More particularly, the invention relates to an improvement in a shipping pallet arrangement wherein the loading and securing operations are greatly facilitated.

In the transporting of large and heavy objects on transporting units such as railroad or box cars, many difficulties are encountered in properly securing the articles against possible damage during shipment. It is extremely desirable that the articles be securely positioned relative to the box car and relative to each other so that damage to the objects will be held at a minimum. In order to facilitate transportation the practice has developed of utilizing a series of pallets which may be positioned in superposed relation. Various difficulties, however, have been encountered in an attempt to provide suitable tie-clown means for securing the series of stacked pallets Within the box car or truck. During the loading operation the pallets containing the articles to be shipped are positioned within the box car by moving the pallets through an opening positioned either at the rear or at the side of the car. It is usually a relatively simple matter to fasten the rear end of the pallet once it has been placed in position. Since the sides of the car, however, U

are usually immediately adjacent to the outermost sides of the palleting arrangement, it is difiicult for an operator to find sufiicient access so that he may secure the forward end of the pallet to the car. The necessity of securing both ends ofthe pallet is believed to be obvious since any sudden stop of the truck or humping of the box car may be sufficient to upset the pallet and thus result in damage to the articles carried thereon. Applicant has provided an improved palleting arrangement wherein the pallets may be stacked in superposed relationship within a transporting device where both ends of the pallet are securely held within the car permitting the maximum use of possible space therein. It is a prime object of the invention, therefore, to provide an improved palleting arrangement.

A further object is to provide a series of superposed pallets adapted to be positioned in a transporting device in a novel manner wherein the pallets may readily be secured against relative movement.

A still further object is to provide a series of pallets that may readily be positioned in superposed relationship by the utilization of separating frames.

A still further object is to provide an improved structure for facilitating loading of pallets on a transporting device, the structure including tracks wherein the pallets may readily be moved into position.

A still further object is to provide a series of superposed pallets that may be positioned within a transporting device, the pallets including an improved means wherein the pallets may be readily secured against possible dislocation.

These and other objects will become more clearly apparent from a reading of the description when examined in connection with the accompanying sheets of drawings.

In the drawings:

Figure 1 is a side elevational view partially in section showing a transporting device containing the improved palleting arrangement.

Figure 2 is a cross sectional view taken substantially along the line 2-2 of Figure 1.

Figure 3 is a plan view of a single pallet of the type used in an improved palleting arrangement.

Figure 4 is a front View in elevation of the same.

Figure 5 is a side elevational view of the pallet shown in Figures 3 and 4.

Figure 6 is a sectional view generally taken along the line li6 of Figure 1.

A railroad car or transporting truck is generally designated by the reference character Ill. The truck It] consists of a bottom H which is suitably supported on wheel trucks I2, only one of which is shown. The wheel truck includes conventional car wheels I3 as best indicated in Figures 1 and 2. The wheel truck [2 may be secured to the bottom H by a conventional connecting structure generally indicated at I4. Vertical side walls l5 and end walls l6 extend upwardly from the bottom I I in conventional style. One of the side walls is provided with an opening ll indicated in Figure 1.

A palleting arrangement consisting of a series of superposed pallets is generally indicated by the reierencecharacter 29 as best shown in Figures 1, 2, and 6. The pallets are designated by the reference character 2| and reference is made to the disclosure shown in Figures 3, 4, and 5 wherein the pallet is shown in detail. Each pallet 2! consists of a horizontal base 22. The base 22 consists of a plurality of longitudinally extending brace members 23 which are connected at their ends by means of transverse beams 24. The pallets 2l are especially suited for carrying articles such as motors or engines generally designated by attate the reference character 25. Each pallet is adapted to carry three engines, and cradles 25 are positioned at the forward ends of each pallet 2 I. The cradles 26 are shaped to the contour of the engines 25 so that one end of the engine is suitably nested in each cradle. The rear portion of the engine may be supported by angle irons 2! which extend vertically and are suitably connected to supporting members 28. The angles 21 may be cut out as indicated at 29 so that projecting portions of each engine may be suitably supported on the angle irons 21 as generally indicatedat 30.

As best shown in Figure 3 and 4 each pallet is provided with a plurality of projecting bracket structures 3 I. These structures are positioned in transverse relative relation and are provided to rigidly support a retaining member consisting of an angle 32. The angle 32 projects outwardly from the forward end of the pallet 2| and a similar angle or retaining member 33 is positioned at the opposite side of the pallet 2| as best shown in Figures 1 and 5. The purpose of these retaining members will presently become apparent. Each pallet 2| is supported by upright tubular leg members 34 which are rigidly secured at the four corners of the pallet. The tubular leg members 34 project downwardly and upwardly with respect to the base 22 so that the base is supported free of the-truck or ground when positioned in article carrying relation. Each tubular leg member 34 includes a foot 35 which is rounded at its end in order to facilitate sliding movement of the legs on a flat surface.

As best shown in Figures 1, 2, and the pallets 2| may be positioned in superposed relation by the utilization of separator frames 35. In order to position one pallet 2| on top of the other two, separator frames 36 are utilized. Each separator frame includes a pair of spaced upright legs 31. The legs 3? are of similar construction as the leg members 34. A cross brace 38 suitably connects the legs 3? in rigid relation. The legs 3! also include feet 39 which may be of a rounded contour for a purpose which will presently be described.

The truck or car ID is provided with a track 46 which is positioned on the bottom The track consists of channels 40 which have their legs extending in an upright direction. The channels 49 are transversely spaced and extend longitudinally with respect to the bottom In order to properly load the pallets 2| the engines are positioned so that the cradles 26 and the angle irons 2'! suitably support the engines in an upright position. After one pallet has been loaded with the three engines the separator frames 36 are placed in position. Two separator frames 36 are utilized for each pallet. The legs 31 are positioned in vertical alignment so that thefeet 39 are positioned in telescoping arrangement with the tubular upright legs 34 of the pallets 2|. After the frames 36 are in position the pallet 2| is positioned on the frames 36 in superposed relation. The legs 34 of the upper pallet are positioned so that the rounded feet engage the upper ends of the legs 3'! of the separator frame 35 in telescoping or socket-like engagement. In this manner the pallets are rigidly supported in superposed relation. After the pallets are thus stacked they are positioned so that the rounded feet 35 of the lowermost pallet engage the channels in nesting engagement. .The stacked pallets may thereupon be moved to the forward or rearward end of 4 the car in order to position the same for transport. As the first group of stacked pallets is placed into position the retaining members 32 positioned at the forward ends of the pallets are, as best shown in Figure 1, moved into position beneath a retaining member 4| which is securely connected to one of the end walls H; of the car. The retaining members 4| extend transversely and are substantially coextensive with the retaining members 32. As best shown in Figure 1 the retaining members 32 and 4| may be positioned in somewhat spaced vertical relation since these members need not engage each other under normal operating conditions. After the first group of stacked pallets has been thus positioned the operator ties d wn the rear end of the stacked pallets by means of flexible cables 32. This arrangement is best shown in Figures 1 and 2. The flexible cables are positioned so that they are connectedat one end by means of eye-bolts 43 to one of the side walls I5 of the car. The cables are then stretched over the articles positioned on the pallets and they are 7 securely connected by means of hooks 44 and eye-bolts 55 to an opposite side wall l5 of the car. The cables are stretched sufficiently taut so that the pallets are rigidly secured in the tracks 48 against possible vertical displacement.

After the first group of pallets has thus been stacked a subsequent group is moved along the tracks 46 to a position wherein the retaining member 32 of the pallets in the second group is in the position shown in Figure 1. It may be again pointed out that in this position the retaining member 32 is positioned in vertical registry with the retaining member 33 of the adjacent pallet. The retaining members need not engage each other during normal operation since they are provided merely to act as hold-down means during unusual conditions arising through the humping or sudden stopping of the car or transport device.

Subsequent groups of stacked pallets may be positioned in the car in the same arrangement. It can readily be seen that in order to properly secure the pallets against vertical displacement during ordinary transport the cables are sufficient to secure the pallets to the transport device. During abnormal conditions where the cars may be humped or sudden stops may occur the retaining members 32 and 4| and 32 and 33 .must do is to place the flexible cables over the articles in the position shown in Figure 2 where one end of the device is securely held against vertical displacement. The cable is eifective to secure the articles on the pallet and .at the same time the pallet is secured to the bottom of the car. The opposite ends of the pallets are also positioned against possible vertical displacement by means of the retaining members which effectively operate as above indicated during extraordinary conditions. The track provides a means whereby the upper and lower pairs of stacked or superposed pallets may readily be moved in position and removed when the transport device has reached its ultimate destination.

It is believed the many advantages of this im-' proved construction are clearly apparent. The specification describes and the drawings show a preferred embodiment but it must be understood that changes in design and structure may be made without departing from the spirit of the invention as shown or the scope thereof as defined in the appended claims.
