10 Claims.

This invention relates to the art of packaging for shipment such objects as building bricks, fire brick, paving brick, tile, cobble stones, wooden blocks and the like, that is to say, articles of reasonably regular outline, small size and relatively great weight. For sake of convenience the term brick will be used herein as generic to all such objects.

The most important object of the invention is to improve the efliciency and decrease the cost of packing and shipping bricks.

Another object of the invention is to facilitate the assembling of large numbers of bricks into compact self-sustained shipping units.

Still another object of the invention is to provide an improved form for use in preparing a package of bricks assembled and bound into a com-pact stack capable of withstanding rough handling without disintegration and arranged in a form in which loading and transporting operations may be carried out with greatly increased facility and safety.

An important feature of the invention resides in a combined pallet and form by means of which a package having the desired characteristics may quickly be assembled.

Another feature of the invention comprises first forming a plurality of spaced rows of bricks, encasing said rows with tough, flexible material, laying courses of brick on the encased rows to 'form a compact stack supported at spaced intervals on said cased rows of bricks, and then binding first the stack and then the combination of the stack and supporting rows with metal bands.

Another feature of the invention consists in a rectangular stack of bricks, cased and bound as a unit, and bound to a plurality of spaced rows of bricks serving to provide parallel spaces between rows for the accommodation of the forks of a lift truck.

In addition to the obvious advantages of speedy facile packaging afforded by the features of the .invention, it is perhaps equally important that a package of bricks assembled in accordance with the invention is so designed that it can be handled without fear of disruption or chipping of the contents; moreover the complete package consists only of the bricks, a casing of paper board and the retaining bands. In other Words, there is no heavy apparatus Which adds to the shipping weight.

These and other objects and features of the invention together with incident advantages will be more readily understood and appreciated from the following detailed description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings in which:

Fig. 1 is a view in perspective of the metal form about which the package is assembled,

Fig. 2 is a view in perspective of the form to which has been added the bottom casing sheet, the bricks which are to form the legs of the brick pack and a portion of the bricks forming the package,

Fig. 3 is a view in perspective showing the assembled brick stack with a portion of the upper casing material in place,

Fig. 4 is a View in perspective showing the assembled brick package with all of the upper casing material in place and a portion of the wire binder in place,

Fig. 5 is a view in perspective of a completed package elevated from the form in which the package was assembled,

Fig. 6 is a view in perspective of :an alternative embodiment of the form constructed of wood and metal.

Referring first to Fig. 1, there .is provided a base or form on which the bricks are assembled for packing. The form comprises a platform in on which are welded or otherwise secured, for example by means of bolts, a series of six parallel rows II, l2, l3, l4, l5 and 16 of ledges I! designed to serve as supports for casing material and base rows of bricks as shown in Figs. '2, 3 and 4 and at the same time provided for grooves or slots through which binding wire or bands can be passed for the purpose of encompassing the completed package as shown in Figs. 4 and 5. The ledges H are each composed of a bottom member l8, side members l9, end members 20 and upwardly extending parallel walls 22 and

parallel walls

22 and 25. Adjacent side and end members are secured at the edge 2! thereof, for example by a continuity of the sheet metal or a welded joint. Alternatively, the ledges l1 may be die-stamped from sheet metal or cast in the form as shown in Fig. 1. Also as an alternative, the bottom member I8 of the ledge I! may be eliminated and the side members I9 and end members 20 may be welded to the platform l0.

Pairs of parallel walls 22

andparallel walls

22 and 25 extend upwardly to a height sufficient to provide upwardly opening channels for easing material and bricks placed in the channels formed by parallel walls 22 and

parallel side walls

22 and 25 as shown in Fig. 2. The parallel side walls 22 and the

parallel side walls

22 and 25 have slots 2'4 reaching to the platform l and aligned transversely of the walls for accommodating banding material extending transversely under the base rows of bricks. These channels are open at both ends. The adjacent sides l9 and the ends 20 extend upwardly to a height sufficient to elevate the casing material and bricks above the platform ID as shown in Fig. 2 to provide grooves or slots for the passage of binding wire or tape under the casing material. The ledges I! are spaced on the base plate ID to provide

grooves

23 and 24 between the ledges H. The

respective grooves

23 and 24 between opposing ledges are in alignment across the length and breadth of the base plate In. The outermost side walls 25 and the end walls 26 extend upwardly to a height greater than that of side walls 22 to provide a retainer for the lower portions of the casing material as shown in Figs. 3 and 4. The number of ledges H in a given row and the relative lengths of respective ledges I1 are determined by the number and spacing of grooves 24 desired for the passage of binding wires or tapes.

The dimensions of the platform I0 and of the ledges I! are determined in part by the size and shape of the bricks which are to be packaged and in part by the manner in which the bricks are to beplaced in the form, for example, on

their sides or their faces, and parallel to or transverse with respect to the rows of ledges H.

' as in Fig. 5.

The sheet metal employed in fabricating the platform I 0 and. the ledges IT is selected for thickness and strength characteristics to be at least suflicient to support the weight of the load of bricks of the type and quantity for which the form is to be employed,'desirably with a safety factor sufiicient to insure that the ledges U will withstand crumpling or buckling under the weight of the bricks. It has been found satisfactory to use 12 gauge sheet steel for the ledges I1 and 16 guage sheet steel for the platform Ill. Although the form illustrated in Fig. 1 is constructed of sheet metal, any other suitable material may be substituted. The entire form may be stamped or otherwise fashioned from sheet steel, or billets of steel or other metals. Various other types of construction may be employed insofar as they result in a form which will achieve the purpose in substantially the manner pro- 'vided herein.

Upon the form described in the preceding paragraphs there is placed a sheet 2! of heavy corrugated paper, fiberboard, chip board, or the like, that is to say, a tough flexible material which may be creased and folded without rupturing but which tends to hold its folded shape. The folds are made to form channels as in Fig. 2, conforming to the contour of the channels provided by the

side walls

25 and 22 and also by opposing side walls 22 in the interior of the form. Rows of bricks 28 are placed in the outermost channels over the conforming sheet 2'! and the end flap portions 29 of the sheet 2] are folded over the rows of bricks 28. A row of bricks 30 is laid transversely in the interior channel formed by the opposing side walls 22. The bricks may be laid on their sides or faces, depending upon the manner in which the form is designed. A full course 3| of bricks is laid over the flaps 29, the exposed portions of the sheet H and the center row of bricks 28, the bricks in the course 3| being laid side by side and parallel to the rows of bricks 28. The bricks in course 3| may be laid flat or on side as desired. In Fig. 2 they are shown on side. Over the course 3| is laid a second course 32 in which the bricks are laid on side and at right angles to the bricks in the first course 3|. The next course 33 is laid at right angles to the bricks in course 32. Additional courses of bricks are laid in edgewise relation and alternating in direction until a package of 500 bricks, more or less, has been assembled as an integral stack.

The next steps in the assembly of the package are illustrated in Figs. 3 and 4 wherein four sheets 34 of corrugated paper are folded about the corners of the stack of bricks and are overlapped to form a continuous casing surrounding the side walls of the stack of bricks. Furthermore each sheet 34 is cut at the corner fold and folded at the top or creased and folded to form a flange 35 which laps over the upper margin of the stack. It will'be noted that the vertical and upper horizontal edges of the stack are protected by the casing 34. The outermost sides 25 and the center ends 26 serve as means for holding the corrugated paperinposition on the stack of bricks previous to the binding operation. The binding wires 42 are inserted in the

grooves

23 and 24 in the space below the stack of bricks and are passed through these grooves from one side of the stack to the other and from the front of the stack to the rear. The binding wire is then drawn upwardly along the respective side walls of the cased stack and then bent over the top where the ends overlap. The wires are then stressed tightly around the stack so that compacting pressure is exerted upon the stack of bricks. The ends of the wires are then twisted to fasten them together as shown at 36 in Fig. 4. In place of wire for binding purposes any banding material such as flat metal strips, pressuresensitive tape or other forms of binding material may be employed,'and the term band as used in the present application is meant to include any of these materials.

The package is then complete and may conveniently be elevated from the form as shown in Fig. 5. For this purpose a conventional fork lift truck may be employed. Thereafter the package may be deposited on any level surface. In the completed package the bricks in the lower rows 28 serve as supporting legs or as a pallet integral with the package.

An alternative embodiment of the metal form shown in Fig. 1 is illustrated in Fig. 6. This form comprises three transverse boards 31 to which three timbers 38 are secured while a platform 39 is secured to the upper surfaces of the timbers 38. Two parallel side walls 48 are secured along their lower margins to the outermost'of the three timbers 3B and extend upwardlyfrom the plate 39. Each side wall '49 is provided with three downwardly extending slots 5! open at their upper ends and extending down approximately to the level, more or less, of the platformSS. In an alternative embodiment, the platform 39 may be grooved at the location of the slots 4| to facilitate the passage of the bands 42 from one side wall to the other.

Secured to the upper surface of the platform 39 are pairs of parallel side Walls formed by opposed angle irons 13 and 44 composed; of aligned sections separated, as it were, by slots 45.

Flat parallel spacers 46, also sectioned or slotted, are secured to the base platform 39 at the base of the side walls 40 and contiguous with the flat vertical walls of the angle irons 43 and M. The package of bricks is assembled on this form exactly as described in conjunction with the metal form as illustrated in Figs. 1 to 5.

As an alternative method of binding the stack of bricks, the bands passing from one sidewall to the'other as in Fig. 6 may be laid over the rows of bricks in the channels after the flaps of the sheet material have been folded over. An advantage of the package shown in Figs. 4 and 5 is that the banding or strapping is all done at the same time after the package has been completely assembled.

Although I prefer to use flexible steel wires for the strapping of the package of bricks, I also contemplate the use of flat bands; the wires, however, are less likely to cut through the corrugated paper casing and grind against the edges of the bricks.

The present application is a continuation-inpart of my co-pending application, Serial No. 110,723, filed August 17, 1949, now Patent No. 2,596,071, granted May 6, 1952.
