11 Claims.

The present invention relates to truck and trailer bodies and more particularly to the load supporting bodies of trucks, trailers, and the like especially suited for use in transporting stacked articles such as cases of bottled beverages and for mechanically loading and unloading the same, as by power operated fork lift trucks.

The transporting of cases of bottled beverages. such as milk, soft drinks, beer, wine and the like by the bottler from the bottling plant to distribution points has always been a time consuming and expensive operation. It has heretofore been the practice to load cases of beverages in stacked relation on flat bed trucks or in truck supported, superimposed, horizontal racks. This has necessitated manual lifting and positioning of a multiplicity of cases and the manual securing of the cases once in position for transportation. The

, unloading likewise is an extensive manual operation. Such trucks have generally been limited in their capacity for carrying such articles far short of the full weight carrying capacity of the truck, because of the characteristically bulky arrangement of the cases.

Considerable experimentation has been directed to the development of improved means for transporting bottled beverages from the bottling plant to points of distribution. One such device has made provision for hydraulically tipping portions of the truck bed to aid in loading and unloading. t

have been tied or otherwise secured in place, they have been easily displaced therefrom and the high center of gravity has made the operation of such trucks diilicult and under certain circumstances dangerous.

It has been the conventional practice to stack cases of bottles coming from bottling machines onto pallets and to transport the pallets and their supported cases to truck loading position by means of power operated fork lift trucks. These fork lift trucks are employed to position the Further, the :2.

pallets adjacent to the transporting truck. from which position they are manually loaded.

It is an object of the present invention to pro vide an improved load supporting body for trucks, trailers and the like onto which pallet supported articles may be expeditiously loaded and unloaded by fork truck operation and on which such articles are dependably maintained during transportation Without the employment of auxiliary retaining means.

Another object is to provide a load supporting body for the aforesaid vehicles having increased effective carrying capacity for bottled beverages and other bulky articles as compared with conventional truck beds of the same area.

Another object is to provide an improved body for trucks and trailers particularly adapted to the transporting of stacked cases of bottled beverages and other bulky articles at a lower center of gravity than has heretofore been known in such vehicles.

Another object is to obviate all manual lifting and positioning of cases of bottled beverages in loading and unloading said cases from transporting means, such as trucks, trailers, wagons and the like.

Another object is to provide a body of the character described adapted to translate gravitational forces and road traversing vibration and jostling into forces imposed upon articles supported by the body to urge the same into body retained position.

Other objects are to provide improved elements and arrangements thereof in a device of the character and for the purposes set forth that are economical to manufacture, dependable in operation, durable in construction, and which eliminate all moving parts.

Still further objects and advantages will become apparent in the subsequent description in the specification.

Referring in greater'detail to the drawings:

The support body of the present invention, indicated generally by the reference numeral Ill, is illustrated in the drawings as mounted on a truck II for earth-traversing movement having a specially constructed frame I2. It is to be understood that the support body may be suitably` employed on a trailer, wagon, or other vehicle without departing from the spirit or the scope of the present invention. For purposes of descriptive convenience the truck II is shown as employing a cab, fragmentarily illustrated at i4. The frame is supported at its forward end for earth traversing movement on front wheels, not

shown, and at its rearward end by the rear wheels When the support body I0 is employed on a truck, the frame I2 is of a modified form believed unique in truck frames. As shown in Fig. 5, the

frame I2 is conveniently formed of channel iron,

as is the conventional practice, or other material of sufficient rigidity and strength. The frame I2 has a forward portion I6 in supporting relation to the cab I4 and the engine of the truck, not

shown, a narrowed portion I'I rearwardly adja- I cent to the forward portion, a portion I3 symmetrically located relative to the rear wheels I3, and a rearward narrowed portion I9. The por tions are arranged in concentric alignment rela tive to the longitudinal axis of the truck. The forward portion I6 and the portion I8 are conveniently of the same width and may readily be of the usual width for the members of truck frames. The narrowed portions I'I and I9 are preferably of the same width and substantially narrower than the portions IG and I8. By way of illustration and not of limitation, the portions I 6 and I8 may be approximately 34 inches in width, as many conventional truck frames are,

and the narrowed portions approximately 18 inches in width and achieve the results desired. Other dimensions and ratios may be employed, but these exemplify satisfactory embodiments.

Each of the portions IB, II, I8, and I9 are formed from substantially parallel channel iron members interconnected at their ends. The rearward ends of the channel iron members of portion IIS and the forward ends of the members of portion II are interconnected by a transverse strut 2l of channel iron or other suitable material. Similarly, a pair of central transverse struts 22 interconnect the rearward ends of the members of the portion I1 and the forward ends of the members of the portion I8 as well as the rearward ends or the members of portion I8 with the forward ends of the members of the portion I9. A rearward transverse strut 23. conveniently of a length substantially equal to the struts 22, interconnects the rearward ends of the members cf the portion Ill. The resulting truck frame possesses the desired strength and rigidity characteristic of truck frames and provides the narrow portions Il and IS for purposes subsequently described.

The support body IU employs a secondary frame 25, of the form illustrated in Figs. 2 and 3, rested up on and secured to the truck frame I2. The secondary frame includes a forward, horizontal, transverse channel member 26, a pair of horizontal, central, transverse, parallel channel members 21, and a rear, horizontal, transverse channel member 28. The channe1 members 2G, 2l, and 28 are secured together in horizontal transverse parallelism, as by welding a pair of elongated Z structural members 29 in longitudinal spaced parallel relation across the upper edges of said channel members. This secondary frame 25 is rested upon and secured by any convenient means on the upper side of the truck frame I2 with the channel member 2E located on the forward transverse truck frame member 2l, the central channel members 27 located on the central transverse truck frame members 22, and the rear transverse channel member 28 located on the rear transverse truck frame member 23. The secondary frame 25 is thus xedly positioned with the Z structural members 29 located longitudinally of the truck frame I2 and transversely centered thereon.

A central wall is provided longitudinally of the truck by a pair of panels 32, of sheet steel or the like, each secured to a Z member 29 and upwardly extended therefrom in converging relation to a juncture as at 33. As evident in Figs. 2, 4, and 5, the lower margin of the panels over the portion I8 in the frame terminates flush with the upper edges of the central transverse channel members 21. The lower margins of the panels 32 are extended at the portions I1 and I 9 between, and an appreciable distance below, the respective transverse channel members 26 and 21. and 2l and 28. The narrow portions of the frame Il and I9 accommodate the downward extensions of the panels to aligned, substantially horizontal, lower edges at approximately the axial height of the rear wheels I3. The panels 32 bear an appreciable amount of weight during operation and thus are appropriately reinforced by strut plates 35 interconnecting the panels in Xed spaced relation, as shown in Fig. 4. The panels are conveniently joined at 33, secured to the Z members 29, and mount the strut plates 35, as by welding. Each of the panels 32 provides an inner wall for a forward load containing compartment 38 at each side of the truck body, as illustrated in Figs. 1 and 5 of the drawing. Each of the forward compartments 38 is substantially longitudinally coextensive with the narrowed portion I1 of the frame. Each panel 32 also provides an inner wall for a central load containing compartment 40 on each side of the truck longitudinally coextensve with the portion I8 of the frame and an nncrwall for a rearward load containing compartment 42 at each side of the truck coextensive with the rearward narrowed portion I9 of the truck frame.

As previously mentioned and as shown in Fig. 4, the panels 32 upwardly converge for the reception of loads thereagainst. The panels converge upwardly to the height of the estimated loads. For descriptive convenience this height is illustrated generally at 43. I'he inward slant for convergence of the panels 32 is not critical but by way of example, when the panels are spaced apart at the Z members 29 approximately I8 inches, it is suitable for them to converge upwardly to a height of approximately four feet above the transverse channel members 26, 2T and 28, at 43, where they are preferably closely spaced and thence upwardly extended for a short distance in parallel relation for purposes of appearance and strength and thence are broken inwardly to their juncture at 33. The panels are provided with erect forward edges rearwardly adjacent to the forward transverse frame member 2l to the anticipated load height shown at 43. The rearward edges of the panels from their lower limit to the anticipated load height 43 are terminated forwardly adjacent to the rearward transverse frame member 23.

A forward transverse panel 44 having a substantially horizontal upper edge portion at the anticipated load height 43, downwardly diverging side edges in substantially parallel relation to the downwardly divergent panels 32 respectively, and a substantially horizontal lower edge portion continuous with the lowermost edges of the panels 32, is mounted transversely of the truck and secured in abutting relation to the forward ends of the panels 32 below the anticipated load height 43. The panel 44 is notched to nt over the frame portion I1 and to fit downwardly along the downwardly extended portions of the panels 32. The peripheral form of the panel 44 is shown in solid and dotted line in Fig. 4. A substantially similarly shaped rearward transverse panel 45 is arranged in abutting relation against the rearward end edges of the panels 32 and ntted downwardly over the narrowed portion I3 of the frame for wardly adjacent to the rearward transverse strut 23. The forward transverse panel 44 provides a forward wall for the compartments 3B and the rearward transverse panel 45 provides a rearward wall for the compartments 42. Intermediate laterally extended partitions 46 and 4l provide both rear walls for the forward compartments 38 and forward walls for the central compartments 40, and rearward walls for the central compartments and forward walls for the rearward compartment 42, respectively. The upper edges of the panels 44 and 45 and partitions 46 and 4l terminate in a common substantially-horizontal plane continuous with the anticipated load height 43. The lower edges of said panels and partitions terminate in a substantially horizontal plane common with the lowermost edges of the panels 32 of the longitudinal central wall. The lateral edges of said panels and partitions terminate in common upwardly convergent planes.

Each of the compartments 38, 40 and 42 is provided with an upwardly and' outwardly extended iioor 50 of sheet metal o1' other suitable material substantially normal to the upwardly convergent panels 32 providing inwardly sloped resting surfaces for loads. The oors of the compartments 38 and 42 are conveniently welded to the lower margin 'of the 1ongitudina1 panels 32 and the lower edges of their respective panels 44 and 45 and partitions 46 and 4l. The floors of the central compartment 40 are welded to the lower margin of the panels'32 which are terminated at approximately the upper edge of the transverse channel members 2l and welded in abutting relation to the partitions 4B and 4l. The door of each of the compartments is formed with a pair of spaced channel portions 52 of substantially rectangular cross section transversely of the truck. The bottoms of the channels at their inner ends are substantially ,flush with their respective oors 50 and extend outwardly therefrom in substantial conformance to the plane of the lower edges of the transverse panels 4 4 and 45 and partitions 46 and 4l. Thus, the bottoms of the transversely rectangular channels 52 are substantially horizontal while their respective doors 50 are out- Wardly inclined. The laterally extended edges of the floors 50 and the channel portions 52 are terminated in the planes of the laterally extended edges of the transverse panels 44 and 45 and the partitions 45 and 41. To strengthen the floors and to impart a more finished appearance to the lateral edges of the floors and channel portions, face plates 53 are downwardly extended from the floors to the lower margins of the channel portions and extend between the channel portions, between the channel portions and the transverse panels 44 and 46. and between the channel portions and the partitions 46 and 4l respectively.

Each compartment is adapted to contain a plurality of stacked cases 54 of bottled beverages 55 or other articles to be transported. The bottle beverages are normally arranged in the cases by a bottling machine and the cases stacked on a pallet, indicated generally at 51 in Figs. 1 and 4. The pallets may be of any suitable construction and are well known in the art. The pallets are either notched, as at 58, or otherwise constructed so that the pair of forwardly extending forks employed on power operated fork trucks may slide under the pallets when they are rested upon the door for elevation of the pallets preliminary to their transportation. The longitudinal wedgeshaped channel portions 52 provide for the reception of the forks so that the pallets may be deposited directly upon the doors 5U of the compartments and thus all manual loading be eliminated. The pallets have cases of bottled beverages stacked thereon and are elevated by the fork truck, not shown, and conveyed directly to the transporting truck where the pallets and the supporting cases of bottled beverages or other articles are positioned directly upon the floors 50, the forks of the fork truck subsequently being lowered and withdrawn from the channel portions 52. It will be observed that as the pallets are deposited on the floors 5,0 they are tipped inwardly into the attitude shown in Fig. 4 so that the stacks of cases are leaned against the panels 32 of the longitudinal central wall of the truck body of the present invention.

Means is provided for concealing the face plate 53 and the outer ends of the fork receiving chan nels 52 and for concealing the pallet when posi tioned on the door member of a compartment. This concealing means is in the form of a door 6D hinged at 6I to an. angle member E2 secured to and extending longitudinally of the truck body along the lower outer edge of each compartment. The door is pivotal to a position concealing the face plate 53, the fork receiving channels 52 and the pallets 5,1 and is also movable outwardly an 'l downwardly to a depending open position so that the outer openrportions of the channels 52 are exposed for entry of the forks of a fork truck for loading or unloading purposes. The doors El] are yieldably held selectively in close-rl or in open position by providing toggle springs 63 for each door, which are in the form of helical torsion springs having ends connected at B4 to brackets 55 secured as by welding into the corners formed by the junctures of the floors 5D and their adjacent 'face plates 53. The toggle springs are connected at their opposite ends, at 66, to brackets 67 secured by welding to the' inner faces. of each door and extended inwardly therefrom. The connection 56 of each spring to its respeck tive door is located relatively to its other ccnnection 64 and the hinge 6| of the door so that a toggle effect is obtained with the connection 66 moving to opposite sides of dead center or a straight line between the pivot of the hinge 6I and the connection 64. This arrangement yieldably maintains each of the doors either in closed upwardly extending concealing position or in downwardly extending depending open position, as desired.

The body is additionally provided with a storage compartment 1D at its forward end adjacent the cab I4 of the truck for containing individual pallets or empty bottle cases for the convenience of the operator of the truck. The storage compartment is provided with a pair of inner plates 'Il extending vertically adjacent and downwardly from the outer longitudinal faces of the widened portion I6 of the frame of the truck. The compartment is also provided with a sheet metal forward wall 12 which also forms the forward end of the truck body and is located tranversely of the body in spaced parallel relationship forwardly of the forward wall 45 of the forward compartments 38. A sheet metal floor 'I3 extends horizontally across the lower portion of the storage compartment 10 for supporting articles therein. A door, not shown, may be pivotally mounted in closing relation to the outer sides of the storage compartments 1U.

The rear end of the truck body is provided with a rear finishing plate 18 which covers the entire rear end of the truck body and is rolled forwardly and secured, as by welding, to the outer edges of the wall 45 of the rear compartments 42.

OPERATION The operation and utility of the present invention is believed to be apparent from the foregoing description but is briefly summarized at 'this point. In the'loading and unloading of bottled beverages, for example, the bottle cases 54 are stacked on the pallets 51. The supporting area of the pallets 51 are conveniently such that each supports eight stacks of bottle cases, as shown in Figs. 1 and 4, and each pallet is of a width to slide into the compartments conveniently without binding` Each forward compartment 38 and veach rearward compartment 42 conveniently has a height that will contain a stack of bottle cases containing bottles seven tiers high, as shown in Fig. l. Each of the central compartments 49 is not as deep as the adjacent forward and rearward compartments and conveniently will con- 5 tain a stack of bottle cases containing bottles five tiers high, as illustrated in Fig. 4.

When it is desired to load a compartment with stacked bottle cases, its respective door 60 is pivoted from its normal, upwardly extending or concealing position to a downwardly depending open position so that the forks of a fork truck may enter into the channel portion 52 of the compartment. A fork truck is directed to insert the forks of the truck under the pallet supporting stack bottle cases and is operated to hoist the stacked cases and to move the cases to a position immediately outwardly of the compartment to receive the bottle cases. The fork truck is moved to extend the forks thereof into the channel portions 56 of the compartment until the cases are in contact with the rear panel 32 of the compartment. The forks of the fork truck are thereafter lowered, first bringing the outer edge of the pallet in contact with an outer portion of the floor 5U of the compartment, and further downward movement of the forks permits the pallet and stacked bottle cases to tilt inwardly until in rm supported relation on the floor of the compartment inclined against the panel 32. The

CII

forks of the fork truck are thereafter removed from the recesses 56 of the compartment and the respective door 60 of the compartment pivoted upwardly to a position concealing the face plate 53 and channel portions 56 of the compartment and the outer edge of the pallet therein. The pallet supported stacked bottle cases may be as conveniently removed from the truck body by reversing the series of steps previously enumerated.

From the foregoing description it will be seen that a truck body is provided by the use of which stacked bottle cases or like stacked articles may be quickly, easily, and conveniently loaded thereon or removed therefrom by the use of a power operated fork truck for handling the stacked cases. By providing the forward compartment 38 and the rearward compartment 42 extending appreciably downwardly below the truck frame on which it is supported, the body has greater carrying capacity than truck bodies heretofore provided. By constructing the forward and rearward compartments downwardly below the trucl; frame, the center of gravity is lowered relative to conventional truck bodies bearing similar loads. The truck body is relatively inexpensive as to the materials required and is economically welded into a one-piece construction. The body is of rugged construction and of comparatively light weight, being formed almost entirely of sheet metal reinforced by few structural members welded to each other and tol the sheet metal members of the truck body.

The inclining of the pallets 51 and the cases of other articles borne thereby and the leaning of the loads inwardly against the longitudinal center wall of the body formed by the panels 32 clependably maintains the pallets and load on the truck during transportation without any auxiliary load securing means. Jostling and vibration during transportation tends securely to maintain the loads on the truck because of the inwardly sloped floors 50. The right-angular relationship of the panels 32 to the floors 5B maintains the cases of bottled beverages 54 or other articles in original stacked relation on the pallets so that the pallets and their loads may be conveniently removed by a power operated fork lift truck by inserting the forks into the channel portions 52, raising the forks to return the pallets to horizontal positions and the stacked articles to erect stacked positions thereon, further elevating the forks to clear the pallets from the oors 50, backing the power operated fork lift i truck so as to remove the forks from the channel portions 52, and thence conveying the removed pallet and stacked material to any desired depositing position.
