United States Patent O 3,105,599 BARREL LOADBNG Henry 0. Hausermann, Portland, Oreg., assigner to Blitz-Weinhard Co., a corporation of @regen Filed Nov. 13, 1959, Ser. No. 852,887 Claims. (Cl. 214-105) This invention relates to the handling of barrels, and more particularly to a novel construction enabling Ithe expeditious stacking of barrels in vertically spaced tiers and subsequent transport of these barrels from one location to another and/or storage of the barrels. The invention has particular utility in connection with the handling of beer kegs, which because of their size and weight are diicult to move other than by rolling and dilicult to shift from a horizontal to an on-end position. 'I'he invention thus is discussed in connection with beer kegs or barrels, but it should be understood that the invention is applicable to the handling of related objects wherein similar problems of moving and storage exist.

In the past it has been customary to stand beer kegs on end, during storage or during their transport in a vehicle. Kegs are usually rolled to the vicinity of their final stacked position, and this requires manhandling of the kegs to place them on end. The on-end position of a keg is not a stable one. Plural kegs arranged on end and in vertically spaced tiers are susceptible to inadvertently ybeing dislodged, as a corner keg is easily kicked out of place with the result that a large quantity of barrels falls to the ground. Thus this type of stacking has not been used in transport vehicles, and kegs are either stored in one level only, or if stored iu two levels, supported on distinct platforms. VPallet handling of kegs also usually has relied upon standing the kegs on end, and this requires turning of the keg and produces anunstable arrangement.

This invention contemplates a pallet and slip sheet construction for stacking kegs wherein multilayers of beer barrels may be stored or transported with the barrels on their sides and in snug adjacency. The barrels seat themselves in position, and tend to lock themselves from relative movement. The result is a lstable arrangement ideally suited for the transport of kegs over short or long distances. Using the pallet and slip sheet construction of the invention, tiers of barrels or kegs three high have been transported, and tiers Ve and six high have been stacked for storage with entirely satisfactory results.

According to this invention, the pallet takes 'the form of an expensive, substantially ilat-topped panel that forms the supporting means in the pallet. This panel is substantially ilat, -to accommodate the easy rolling of a beer keg thereon. The panel is supported above the ground by a spacing means, preferably by critically placed blocks, to enable the forks of a fork lift tractor or similar lifting device to be inserted under Ithe panel, from any side of the panel. Formed in the pallet are plural apertures or cutouts that are to receive the bottom sides of beer kegs with the kegs in a horizontal position. Each cut out is made small enough to hold a keg so that its bottom side does not protrude through the thickness of the panel and below the bottom thereof, and thus kegs nested on the pallet are not contacted when :the forks of a fork lift tractor are inserted beneath the panel. Barrels Patented Oct.. 1, 1963 ICC placed on the pallet have ends that are snugly adjacent each other, and sides in close proximity.

To stack an upper tier of barrels over a lower tier, slip sheets are used which have apertures or cutouts conforming in size substantially to the size of the cutouts just described. Each cutout seats on the top side of a lower barrel, and seats the bottom side of `an upper barrel. The cutouts are of such size that the barrels of the lower tier are kept out of contact with the barrels of the upper tier superimposed thereover. The barrels of the upper tier align themselves with the barrels of the lower tier.

Thus it is an object of the invention to provide an improvided pallet construction which accommodates easy rolling of beer kegs onto the pallet and nesting of the `kegs in position with the kegs snugly packed'thereon.

Another object of the invention is to provide a pallet that employs a panel of relatively simple construction as a supporting means, the latter being effective to hold the bottom sides of beer kegs rmly in place and above possible contact with the forks of la fork lift truck inserted beneath the pallet, and to provide su'ch a pallet that is capable of being lifted from all sides.

Still another object of the invention is to provide a slip sheet for stacking one tier of barrels or kegs over another, such a slip sheet taking the form of a panel having cutouts effective to seat on the top Isides of a lower tier of barrels and seat the lower sides of an upper tier of barrels.

Another object of the invention is to provvide a pallet and Islip sheet construction that enables the stacking of barrels on their sides and in tiers, one over another, with the barrels of an upper tier aligned with the barrels of a lower tier. This is important for space reasons, as most barrels are longer than they are Wide, and many vehicles can only be fully loaded if the barrels of successive tiers are aligned and extend all in the same direction.y

`Still another object of the invention is to provide a novel slip sheet that acommodates easy rolling of a barrel therefrom without displacement of the slip sheet by reason of the barrel being near its edge.

Still another object of the invention is to provide an improved pallet construction that may be made economically from readily available materials such as plywood, composition board, etc.

Still another object of the invention is to provide an improved method for loading barrels on a pallet.

Other objects and advantages are attained by the invention, which is described hereinbelow in conjunction with the accompanying drawings, wherein:

FIG. l is an end view of a pallet loaded with three vertically spaced tiers of barrels, with the barrels on their sides and with the bottom tier supported on the pallet and adjacent tiers separated by a slip sheet as contemplated by this invention;

FIG. 2 is a view along -the line 2-2 in FIG. 1 illustrating the profile of a slip sheet and notches indented therein to accommodate rolling of a barrel on and olf the sheet;

FIG. 3 is a view along the line 3 3 in FIG. l illustrating the profile of the pallet, and showing in dotted outline how the beer barrels may rest thereon;

FIG. 4 is a side view of a pallet supporting a bottom tier of barrels and illustrating how the pallet may be picked up from one of its sides by the forks of a fork lift tractor;

FIG. 5 is an illustration of a loading station of the type that may be employed ttor stacking barrels as contemplated by this invention; and

lFIGS. 6 and 7 are enlarged views illustrating how cutcuits present in the construction seat the sides of barrels.

Referring now to the drawings, at 10 is indicated generally a pallet adapted to rest on the iloor and normally used to support the bottom tier of a stack of barrels. Considering the construction of the pallet, it comprises an expansive panel 12 having a substantially Vilat top surface 14 and a bottom 15. The panel in the embodiment illustrated is substantially rectangular in outline. IThe panel may be made from any of various materials having requisite strength and rigidity. In practice, a plywood panel has been found entirely satisfactory, this material being relatively light, strong and inexpensive.

Secured to the bottom of the panel, at the four corners of the panel, approximately'centrally between adjacent corners, and at the center of the panel, are spacer blocks 16 that constitute spacing means holding panel 12 above floor level. These are `aligned in rows extending along the length and transversely of the panel, as shown in FIG. 3. Secured to the underside of .fthe spacer blocks and parallel to a set of opposed end edges 118, 19 of the panel are strengthener slats or boards 20'. FPhe strengtheners connect rows of blocks

adjacent end edges

18, 19, and a center row of blocks disposed between these end edges. The spacer blocks and strengtheners together support panel 12 above the lloor so as to permit the insertion of the forks of fork lift tractor beenath the panel. Note that the construction described accommodates the insertion of such forks from any of the four sides of the panel.

Formed in panel 12 and arranged in plural rows are elongated cutouts 26 that constitute seating means for barrels. These are in substantial alignment in a direction extending transversely and longitudinally of the cutouts. The cutouts are shaped to receive or seat middle portions of the bottom sides of barrels with the barrels or kegs disposed horizontally and aligned with the cutouts.

Barrels such as may be stacked using the pallet of the invention are indicated at 30.- The form of barrel shown is typical of a keg design presently used in lnhe distribution of beer. The barrels illustrated vhave

tapered ends

32, 34, and intermediate the ends a central band portion, or belly band '36, of larger diameter than the ends.

When a barrel is properly nested in a cutout 26, the bottom oi' its belly band lodges in the cutout as best shown in FIGS. 1, 4 and 6 and the ends of a barrel are held above panel 12. The belly band 36 has a width that is less than the length of a cutout. The side edges 37 dening a cutout are spaced close enough to hold a barrel above bottom .15 of panel 12. This is to prevent a belly band from coming in contact with the tines or forks of any `fork lift that may be inserted beneath the panel. Thus each cutout has a width that is less than the horizontal span of the barrel band or middle of lthe barrel with the barrel on its side and measuring across the barrel at a level spaced radially inwardly from its bottom a distance equal to the thickness of the panel, such horizontal span being indicated at a and such panel thickness being indicated at b in FIG. 6. The ends of adjacent cutouts in a longitudinal direction are spaced a distance less than twice lthe length of the tapered end of a barrel. lBy reason of this spacing, end-adjacent barrels may be moved to a position in the cutouts where their ends come into snug contact, by shoving the barrels toward each other. Considering the lateral spacing of the cutouts, the centers of adjacent cutouts are spaced apart a. distance substantially equal to the diameter of a barrel and thus when barrels are stacked in the cutouts their sides are closely adjacent. As a result of the con- 4 struction described, barrels nested into the cutouts bear upon each other and in a' manner of speaking lock themselves Vin position.V

As already indicated according to this invention, barrels may be stacked in tiers as shown in FIG. l. Between adjacent tiers of barrels, and holding an upper tier on the lower tier is what is referred to herein as a. slip sheet, indicated generally at 45. kEach slip sheet has a rectangular outline of somewhat smaller dimension than the outline of panel 12. This prevents slip sheets from coming into contact with each other when pallets are stacked side by side.

Each slip sheet comprises a flat-topped panel, indicated a-t 46, which like panel 12 may also be made of plywood and vthe like. Formed in the panel 46 of the slip sheet are elongated and rectangular cutouts 48, corresponding` to cutouts 26 Ain panel 12. These cutoutshave the same spacing with relation to each other as do cutouts 26, and have a size generally corresponding to the size of cutouts 26. During stacking of barrels, a slip sheet is placed over a tier of barrels with top side portions of the belly bands ofthe barrels in the tier protruding upwardly into 'the bottoms of the cutouts. A subsequent tier of barrels may be nested on the slip sheet with bottom portions oftheir belly bands protruding downwardly into the tops of the cutouts. The cutouts have a length which may be the same as the length of cutouts 26. Sides 49 of the cutouts 48 are spaced closed enough together to keep the barrels of an upper tier out of contact with the barrels of a lower tier. Thus each cutout has a width that is less than the horizontal span of a barrel band with Y the barrel on its side and measuring across the barrel at a Ilevel spaced radially inwardly from its bottom a distance equal to one-half Athe thickness of panel 46 (such horizontal span and one-half panel thickness being indicated at c and d, respectively in FIG. 7).

indented into the side edges of slip sheet 45 are notches, indicated at Sti. These have a V-shaped outline, and the apex 52 of a notch is disposed inwardly from the outline of the slip sheet approximately in line with the longitudinal centers of cutouts 43. The notches are important in loading and unloading barrels from the slip sheet. In unloading, for example, when thetirst barrels are unloaded they roll olf without diiculty, since the remaining barrels of the tier serve to hold the slip -s-heet down and in place. The last barrel to be removed, Y however, must be rolled on one edge of the slip sheet without any weight holding down the opposite edge. To prevent the slip sheet from kicking up and causing possilble injury to a workman the notches are provided, and I these enable a barrel to be rolled olf the slip sheet with the barrel leaving the slip sheet at a location spaced in wardly from the outline thereof and near the line of support provided the sheet by the lower tier of barrels.

According to this invention, barrels may be stacked in tiers employing a loading station 53 such as illustrated in FIG. 5. Referring to this figure, 56 indicates a support surface over which barrels are rolled on their sides to the loading station 58. The loading station is equipped with an Ielevator 60, moved up and down by means of vertically shiftable shaft 62. To load a stack of barrels, a pallet is placed Ion elevator`60 and the elevator adjusted using a control box 64 until the top surface 14 of the pallet is substantially liush with surface 56. With the top in this position barrels are readily rolled onto the pallet and over its top surface into a seat#` ing position in the cutouts. On completion of one tier of barrels, the elevator is lowered Iuntil the level of the top of a slip sheet placed over this tier of barrels is sub have been prepared. IOn completion of the stacking of barrels, elevator 60 is raised to lift pallet 12 above floor level, indicated at 66. In thisY position the torks of a fork lift tractor may be inserted underneath panel 12 and the pallet transported to another location, either for storage purposes or to prepare it -for transport. It will be seen that the entire operation requires ionly rolling of barrels into position.

From the above it should be obvious that the invention has a number of advantages over constructions known in the past. The pallets are relatively simple in construction, and economical to manufacture and to maintain. They add little to the weight of the stack. The pallet may be picked up lfrom any of its four sides, which is a decided advantage in loading and unloading vehicles. The barrels are maintained on their sides and not on end, and once a stack is prepared, the barrels on one tier assist in holding the barrels of an adjacent tier in place, through lthe slip sheet provided. The barrels of successive tiers are aligned with the barrels of the lowest tier and all extend in one direction. This is an advantage since it permits stacking of barrels in more confined space.

While there has been described an embodiment of the invention, it is appreciated that changes in the arrangement and/or parts are possible without departing from the invention. It is desired to cover all modiications and variations that would be apparent to one skilled in the art, and that come within the scope of the appended claims.
