Referring in detail to: the drawings,v my improved package is: generally designated I0 and is specifically illustrated as a shipping, package for detachable; steel. sprocket chain. That the invention. may be better understood, the: detailed constructionxof:thischain will. later be set forth but-'- here it; isnotedi' that itis common practise in the trade. to: ship such. chain in the form of fiat sided coils.
The s-izes cof:suchcoilsadepend on the sizes of the links and .alsoionz thelnumber of links in :the length: or section of? chainmade into. the. coil. For-example, .amanufacturer who utilizes the detachable steel sprocket chainein' asparticular connection'may requireimany. lengths or sections of the-chain and he may specify the; lengths as by designating. the link: size and. numberof links: in the-chain.=
At'present; the manufacturer of the. chain provides sections' of the desired lengthand then coils each-length of :chain upon: itself providing, a flat and,-.as:' far as possible, tightly rolled coil. Then wires are-passed. throughthe coilsfrom thev edges thereof or'radially thereof. and brought back over a-flat side :of. the coil andtheend portionsof each piece of: wire are. twisted together; These: wires are kept tight ormade tight so; as to lock the convolutionst of the. coil; against one. another: and make acoilii which. is quite. stifi fiatwise. Also, theseiwires secure.- the "inner andouter ends of the length of. chain.- in; place and; prevent uncoiling of. theilength oflchain formingzthe coil.
The fiat.coilsicrashipment havingbeen'rolled up andrwired' are usually manually trucked-into a' freight car. or the: like for shipment and there the truck unloaded. Attheir destination they 'arein like;mann'er; manually; removed to a.:storage room. Then the manufacturer who is going tofabricate thechain into some article or piece of machinery that he is building must cut or otherwise release the wires above mentioned be fore he can uncoil or extend the length of chain t place it over sprockets or the like in his machine. It will bee appreciated that the above entails a great deal of manual effort and is slow and expensive.
According to the present invention it is not necessary that the lentghs of chain be wired in their coil formations. The present package provides for the retaining of the lengths in their coiled state. Then when the machine builder or the like receives the package he merely opens it and coils of the desired lengths of chain are exposed in a layer and the workman merely selects the coils or picks them 01f the layer, carries them to the proper place and trains them over the sprockets or the like on which they are to be used. There are no wires to be cut or other work to be done making the chain lengths available for their intended purpose.
Heretoi'ore it has been proposed to ship these chain lengths in cartons with the coils flat, one
on top of the other, the cartons being of the proper transverse internal dimensions. This presents a storage problem for, the plant where the chain is packed for shipment and presents a big disposal problem for the plant that has received the shipment. Also, this method is expensive in that a great number of cartons of various sizes, to receive the various sizes of coils, must be provided.
Figs. 7 and 8 show a very short length of the detachable steel sprocket chain and the length of chain in such figures is generally designated II and is shown as including links l2, l3, l4 and I 5. These links are substantially rectangular and each includes side bars 16 and [7, an end bar If! and an eye formation l9, the latter being formed of stock lanced and pressed from between the side bars beginning at the end bars l8 and actually is from the space designated 28, such space being an opening entirely through each link. The end bars 18 being received in the eyes I9, the links are pivotally or hingedly con- "(see particularly Fig. 2) 2|, 22, 23, 24, 25, 26,
21, 28 and 29, each layer containing a plurality of coils of detachable steel sprocket chain. Each of these coils is formed from the desired length of such chain, the desired length being that required by the party having placed the order for or having purchased the chain. Package 10, in
addition to the mentioned layers of chain, includes a pallet 30 preferably made up of corrugated cardboard although the invention is not limited to such a pallet, as various types or constructions of pallets may be used.
The cardboard pallet shown herein for thebe of an inexpensive construction. However, it
must be strong enough to sustain the burden placed on it and for economy reasons it should also be light in weight. The cardboard pallet shown seems to adequately answer these requirements.
Such pallet (see Fig. 5) includes a bottom;,.
piece 3| of corrugated cardboard, a top piece 32 of the same material and these pieces are connected together but held in spaced relation by means of intervening pier-like structures 33. Each of these structures (see particularly Fig. 6) is made of a length of corrugated board of the desired width, rolled or coiled upon itself as tightly as is reasonably possible and adhesively secured in such formation. The construction of a pier 33 in the form of a tight spiral winding of a length of corrugated cardboard is clearly shown in Fig. 6.
These piers 33 being constructed as described are designed'to withstand a very heavy load (lengthwise) without collapsing. It is noted, particularly with reference to Figs. 1 and 5, that these piers are arranged in rows. The desired number of piers to give a pallet of the desired strength are used but then the piers being in rows, the spaces 34 and 35- between each two outer rows are adapted to receive the fork-like portions of lifting and transporting trucks, such as are used in a factory.
In practise, after a package has been formed, one of these hoisting and transporting trucks is brought up to the package with its fork at a level for its prongs to enter the passageways 34 and 35 and then the fork is elevated and the truck driven awa with the package [0 and it may be carried directly into a freight car and there disposed either on the floor of the car or on the top of a previously loaded package or on the top of a stack of previously loaded packages, as occasion demands.
On top of the pallet 30 a bottom device 36 is placed. Such bottom device includes a bottom wall 31 and four short upstanding side walls 38 which are integral with the bottom 31 and have their corners overlapped and secured together as by staples 39. The bottom device 36 is also preferably of corrugated cardboard and its bottom wall 31 is coextensive with or substantially coextensive with the upper sheet 32 of the pallet 30. Bottom device 36having been placed on the pallet 30, the layers 2| of fiat coils of detachable steel sprocket chain are place on the bottom wall 31 of the bottom device. From there on, variations may be practised as will later be suggested, but in the present package I0, a second layer of fiat coils of detachable sprocket chain is placed directly on the upper side of the layer 2|. Such second layer is the layer 22 shown in Fig. 2. I
Thereafter, a sheet 40 of corrugated cardboard is placed on the upper side of the layer 22. Next, a layer 23 of coils of detachable steel sprocket chain is placed on the cardboard separator 40. Then in the package I0, another separtor 4| is placed on the upper side of the layer 23 and the single layer 24 of coils of detachable steel sprocket chain is placed on the separator 4|. Thereafter, a separator 42 is placed On the upper side of the layers of coils 24. Then a layer 25 of coils is placed on the separator 42 in the same manner that the layer 2| was placed on the upper side of the bottom wall 3'! of the bottom device 36. Next the layer 26 of coils is placed directly on the layer 25, the same as the layer 22 was placed directly on the 1ayer2l.
Now, yet another separator 43, also comprising a sheet of corrugated cardboardis placed on the upper side of the layer 26 and three layers of coils of detachable sprocket chain are placed in Of these, the layer 2? is directly on the separator 43. The thelayer2Bis directly .on the 1ayer.2l and layer 29. is directly on the y r'28. Nowa package of. theproper height and weight has been developed. Thereafter, a top device. generally designated 441 15 placed over. the upper layers of the chain. This top device is merely one of. the bottom devices 36. in reverse position. Thus, the topdevice. includes a top wall 45. and four short depending. side walls A6 over.- lapped and secured together at their corners by staples 41.
Now, binders, preferably in the form of flat stripsof. metal, are carried through the pallet under the top wall 32 thereof and up. the sides and. ends of thepackage and across its top and drawn. tight and the ends tied or anchored together. In the drawing, these binders are all designated 48 and their tied or anchored points designatedi lfi; Assuggested, particularly in Fig. 1, these binders are drawn very tight, in fact so much so asto cut somewhat. intothe top 32. of the pallet and intothe cover member 4 5. With this construction, it will be seen that the hoisting and carrying truck may. easily be used to raise the package Iii, carry it to a desired place and deposit it. The palletfacilitates the handling of the package b such a hoisting and transporting truck. It will. be understood. that the weight of the package prohibits its manual handling.
In actual practise, at the present time, these packages average about 2500 pounds each. However, they may be easily and quickly handled by the mentioned type of truck and with such a truck handling the packages, a freight car may be quickly loaded or unloaded avoiding demurrage charges and reducing the labor costs as well as delays in filling orders.
It is to be understood that the package of the invention need not. be of the size. of the package Ill since obviously it is within the concept of the present invention that the package contain a greater number of layers than shown within the package I0 or that the package of the invention contain a smaller number of layers. Further, it will be understood that one of the separators shown may belocated between the upper surface of-each layer and the lower surface of the next uppermost layer. This will become more evident when the full purpose of the separator is better understood. It has been suggested that these separators, as well as the bottom wall 31 of the bottom device 36, be of corrugated cardboard. Such material is of considerable strength but, in the present instance, its use has an additional purpose. The corrugated cardboard is compressible or deformable in that over an area various spaced portions may be pressed inwardl toward one another.
In the present instance, the work to be shipped comprises essentially flat edge portions, such edge portions comprising either of the side bars H or 16 of the. assembled links. The eyes IQ of the links insure that in the coiled links the side bars of the links of one convolution will not be flat against the side bars of the links of adjacent convolutions but-that such side bars will be slightly spaced laterally. This means that on its upper and lower flat surface each coil of the detachable steel sprocket chain is irregular in that there are spaces between the side bars of the links of one convolution and the side bars of the links of the next adjacent convolution. When the coils are placed on one another portions of the links of each coil enter into the spaces between the links of the other coil and thus the superimposed coils may not slide on one another and are, in fact,
" preventedfrom sliding. movement on one another.
To move. the coils relatively laterally.- onemust-hc picked up off the other and then movedlaterally. These spacesare kept at the minimum possible for the saving of space and. alsoto have each coil tightly wound andzlatera-lly; or: sidewisestiff so the inner convolutions donot tend. to move laterally out. of the outer convolutions into a cone-like formation.
These upper and. lower surfaces being rough or irregular as described, when one of the coils, is placed. onv acorrugated or other compressible piece, as. the. bottom wall. 3.1. or one-of the separators 48, 4|, 42 ch43. the lower edges of'the-inr dividual links tend to sinkinto.thecompressible material and the under surfacesof the separators are compressed and. dug into by the upper edges of. the. link of. coils on whichtheseparatorsare disposed; Therefore, the. coils are held against any tendency toedgewise sliding movement. In addition, this. slight embedding of the lower edges of the links intothe separatorslorthe wall 31. and of the upper edges of the linksintothe separators and the top wall as of the topdevice Mservesto hold the coils. against expanding or uncoiling so thatthey. may be shipped. without being wired whether in. themanner above suggested or otherwise.
It is further noted that when onelayer of coils is placed on a previous. layer, the irregular or rough lower sides of the top layer. of coils overlap or interengagewith the irregular or rough; upper sides of. the bottom. layer of. 0011s.. Thus, the layers 2t and 22: of coils are interengagcd in their adjacent or meeting sides so that one layermay not shift edgewise relative to the other. The same is true with respect to thelayersZ'B and126.
Of the layers 21 28..and 29, the-coils of layer 28 will beheldin place by the coils of layer 21. and
.will assist in holdingv the latter in. placegandefurther the .coilsof layer 28 will be holding thecoils of layer 29 against edgewise movement. Additionally the coils of the latter layer, togetherwith the coils of the layer 21, will by the described interengaging relation with the upper and lower surfaces, respectively, of the coils of layer 28v se cure such latter coils against edgewise movement.
For the purpose of further description, reference is especially had to Fig. 3 showing four com-.- plete coils 59, El, 52 and 53 and fragments 54, 55., 5B and 5'! of four other coils, all of the layer, Z1. These coils are resting on the separator 43. There it is noted that the coils are packed'or positioned so that at least one edge of each coil is against an edge of another coil. That is, all the coils of the layers are packed close together so that each coil is in engagement on as many sides as. possible with adjacent coils in each layer (see Fig. 3) the coils at the outer edge of the layer are arranged with the free or outer ends of the chain lengths, comprising the coils, against an edge of another coil of the layer to prevent unwinding. The coils'may be somewhat deformed where that gives an advantage in packing as to have them fit into. an odd shaped space or the like although in the drawing the coils are shown as rather uni+ form. Generally, they will be uniform as to the size of the links or as to the coil diameter since as a rule each coil in a layer is made up of the same length of chain and all the links of the chain in the coils of a layer are preferably of the same size.
With this in mind, it is noted in Fig.3 with respect to the coils 50 and 54, that a portion of the eyes 53 of the outer links of the 001154 are partially entering between theside armscr bars I6 and ll of certain outer links 59 of the coil 50. Similarly, portions of the eyes 60 of certain outer links of the coil 55 enter between the side bars [6 and ll of the links SI of the coil 52. Also, eyes 62 of certain outer links of the coil 56 enter between the side bars of certain outer links 63 of coil 52 while portions of eyes 64 of certain outer links of the coil 51 enter between side bars of certain outer links 55 of the coil 53. Additionally, portions of eyes 66 of outer links of the coil 53 enter between the side bars of links 6? of coil 52 and the eyes 68 of outer links of the coil 50 enter between the side bars of outer links 69 of the coil 52.
These particular eyes, where the eyes of the outer links of one coil enter between the side bars l6 and I! of the outer links of the next adjacent coil, are given merely by way of illustration. Specific examples of this interlocking of the outer links of adjacent coils with all four sides of the coil 52 have been pointed out. However, this or similar interlocking takes place between the adjacent edges of all adjacent coils. It is further noted that not only do the eyes of one coil enter into the spaces between the side bars of links of a second coil, it is equally true that eyes of the second coil enter into the spaces between the side bars 16 and ll of links of the first mentioned coil.
For example, it is noted that while the eyes 62 of links of the coil 56 enter the spaces between the side bars of the links 63 of the coil 52, it is likewise true that the eyes of links of the coil 52 enter the spaces between the side bars of the links H of the coil 56. Thus, it will be understood that not only are the coils in side-by-side relation with their edges abutting but all these abutting adjacent edge portions of the coils interlock. Thus, a layer of these coils wherein the individual coils are laterally stiff, is itself stiff since the coils are interlocked at their edges. Each layer therefore represents a rather rigid structure.
Above it was pointed out how the irregular or rough upper and lower fiat sides of the coils would overlap or interengage with one another so there is no likelihood of edgewise slipping of a coil of one layer on the coil of another layer. Also, it was suggested that the coils immediately on the bottom wall 37 or on or supporting any of the separators 49, ll, 42 and 43, would become slightly embedded in such corrugated or compressible elements. This is suggested in Fig. 9, which is a section through the coil 53. There it will be clearly seen that the lower edges of the side bars I! of the various links have sunk or become embedded or dug into the corrupated or otherwise compressible separator 4-3. Thus, the separator assists in holding the chain lengths in their coiled formation and against uncoiling and establishes a relationship between the adjacent lengths and also insures that the coils actually on the separators will not shift edgewise.
When a package is received at its destination, a whole carload of packages may be stored in a relatively small space since they may be piled one on the other and, in addition, through the use of the truck as described, a carload of the packages may be rapidly unloaded. It is not necessary that a man or men carry out of the car individual coils. The packages are all identified through stencil markings or the like (not shown) and thus where the receiver needs certain identified chain lengths of certain size links, he merely opens the package bearing that designation. This will be accomplished by cutting the binders 48 and lifting off the top member 44. Then the workman lifts oil the coils of the top layer as they are needed, then those of the second layer, etc. When a separator is reached, it may be lifted off and thrown away or placed in a temporary location, as generally it will later be destroyed by burning or the like. Also, the top member 44, as well as the bottom member 36 and the pallet 30, are preferably all of paper and so may be destroyed by burning.
It is the present purpose that all these parts, while being of considerable strength, shall be of inexpensive construction whereby there is no occasion for the receiver of the package burdening himself with storing these parts with the idea of later returning them to the chain manufacturer. It is desired that they be destroyed and that they be yet so inexpensive that it would not be commercially advisable to return them.
While the invention is shown and described with particular reference to the shipping of lengths of detachable steel sprocket chain in coil formation, it will be understood that the package is adapted for the Shipping of other goods or articles and especially goods or articles having either upper or lower or both upper and lower surfaces rough or irregular so that such surfaces will interlock after the articles are stacked upon themselves or will sink or bite into compressible separators if each layer of the articles has a separater above and below it. Thus, it will be appreciated with reference to Fig. 2, that each of the layers shown may be separated from each of the other layers by a separator or that separators may be employed only between every other layer or every three layers or the like. This latter purpose seems to particularly lend itself to the packaging of the coils of the detachable steel sprocket chain shown.
Having thus set forth the nature of my invention, what I claim is: I
