4 Claims.

Thi invention relates to a shipping container, and more particularl to a nailless, wirebound crate, box or the like for shipping various types and shapes of articles, and is especially adapted for the shipment of a single heavy commodity such as an electric motor, electric transformer, stove, washingmachine, refrigerator, oil burner and many other articles where the product is usuallymounted on a base.

It desired, the article to be shipped is first mounted securely to a base, and the bases with an article secured to each placed upon a conveyonand the wirebound mat forming the sides of the crate or container are wrapped around the article and base. the top also being placed in position during the wrapping operation on the conveyor; if preferred, however, the'assembling oi the crate or container may be effected independently of a conveyor. My invention adapts itself to such conveyor assembling, thus making possible very considerable economy in "the assembling operation.

'rne present invention enables the wrapping of the wirebound mat forming the sides around. the article to be shipped and the top and bottom closures in, such manner as to eilectively protect said'article during shipment as well as to eliminate the necessity of driving nails between the end ,7 closures and the side sections except in extreme cases involving articles or considerable weight.

Among the objects of my invention is to eliminote the disadvantages. present in Shipping containers heretofore known, and to accomplish the advantages set forth above. A

Another object of my invention is to provide a shipping container in which the sides form sections oi a wirebound mat embodyingthe lateral alternate oiisetting oi the cleats to enable folding of the mat without thenecessity oi mitering the ends of the cleats. f

A iurther object is to provide a shippin container oi the class described enabling the double overlooking oi th ends oi the closure cleats to the cleats oi the side sections so as to lock the end closures oi the container against displacement in all directions without the necessity of driving nails between the closure cleats and g the side section cleats.

A still further object is to provide for an anan gular pull of the binding wires at the corner edges oi. th side sections to resist sidewise strain in the container during shipment.

Another object is to provide a wirebound shipping container that is economical, simple, emcient, easy to apply to the article being shipped and that will give a strong interlocking action between the end closures and side sections when the container is secured in closed position.

My invention further resides in the combina tion, construction and arrangement of parts illustrated in the accompanying drawings, and while I haveshown therein preferred embodiments of the invention I wish it understood that Figure l is a perspective view of a closed shippingcontainer embodying my invention.

Fig. '1 is a fragmentary perspective view just prior to the completion or the folding operation, of the upper comer of the container at the meeting ends of the wirebound mat.

Fig. 8 is a view similar to Fig. 7 but showing said corner after the closing operation is completed. I

As seen in Pig. 5, which illustrates the three main parts of the container prior to their being connected in folded position, my container comprises a wirebound mat indicated generally at M having four vertical side wall sections i, t, 3 and l, side wall section i being formed with the upper longitudinal cleat 5, lower longitudinal cleat .8 and vertical slats l and 8. Section 2 comprises the upper longitudinal cleat 9, the lower longitudinalcleat ill, the vertical slats ii, I! and the diagonal bracing slat i3. Section 8 comprises the top longitudinal cleat it, the bottom longitudinal cleat i5 and the vertical The section 4 comprises the top longitudinal cleat l8, the bottom longitudinal cleat it, the vertical slats 20 and II and the diagonal bracing slat 22. The ends of the slats of each of the side wall sections are fastened to their respective top cleats by staples driven over the wire 28 which extends throughout th length or the mat as seen in Figs. 1 and 6, and projects beyond the free end of cleat i in the form ofa transverse section on the a loop 15. which loops may be passed one with- Other objects, advantages and capabilities in- 60 inthe other, the inner loop being bent over the cured to the respective bottom cleats by a similar wire in a similar manner, which latter wire is also provided with extending loops 26, 21 for a similar purpose. Fig. '7 shows two of these loops Just prior to their being secured together, and Fig. 8 shows the same after being secured together upon completion of the closing operation.

As seen in Fig. 5, cleats 5, 9, l4 and I8 of the side wall sections are alternately laterally offset with relation to the next adjacent top cleat,

and the bottom cleats 6, I0, 15 and I9 are likewise similarly laterally offset with the side faces of the adjacent adjoining ends of the cleats in sidewise contact with each other and offset from each other the thickness of the cleat. In other words, these adjoining adjacentcleats are not in longitudinal alignment but are offset with relation to each other a suilicient distance to permit them to contact each other laterally at their ends, and at the same time permit each side wall section to be folded with relation to its adjacent side wall section during the closing of the container around an article to be shipped, which will be preferably fastened in any appropriate manner to the bottom closure B which comprises the two connected sets of parallel cleats fastened one above the other, one set being cleats 28 and 29 and the other set being the cleats 30 and 3|. As seen in Fig. the ends of the cleats of these two connected sets of parallel cleats extend beyond the side of the adjacent cleat so that at each of the four corners there are two extending cleat ends positioned at right angles to each other, one of these ends being above the other. The two sets of parallel cleats are secured together by nails, screws 'or other suitable fastening means 32 to form a rigid unit.

A similar construction is seen in the top closure designated generally at T in Fig. 5, and likewise comprises two connected sets of parallel cleats one set being the cleats 33 and 34 and the other set being the cleats 35 and 36. The top closure T like the bottom closure B is also provided at its corners with extending ends in different planes. For clarity the extending ends of the cleats in the top closure T are designated 31, 38, 39, Mi, M, d2, 63 and 34, while the extending ends of the cleats in the bottom closure B are designated as 45, 38, 4'1, 48, 49, 50, 5! and 52. The binding wire for the bottom cleats of the side sections is designated generally as 53 and like that of the top cleats is secured to the respective cleats by staples which also secure the lower ends of the slats to the longitudinal cleats of the side sections. The ends of the wires protrude in loop or other formation at 26 and 27 as described above. The wires at the top and bottom of the mat forming the side sections in passing from the lower of the offset cleats to thehigher of the offset cleats extend angularly as seen at 54 and 5-5 in Fig. 1. This angular disposition of the wires at the joints gives added resistance against side strain when the container is closed around an article to be shipped. If desired, the cleat 30 oi the bottom closure B may be wider than the cleat 3! to facilitate the fastening thereto of an article to be shipped, it being understood that such article may be secured to one or both of the bottom cleats as desired, and that such cleats may be of any suitable width to accommodate the particular article being shipped.

The operation of closing the container walls and end closures around the article to be shipped (it being preferably understood that the article to be shipped will be already secured to and resting upon the bottom closure B) will be best understood from an inspection of Fig. 5, in which it will be understood that the side wall sections I, 2, 3 and 4 will be folded around the bottom closure B and simultaneously around the top closure T, the latter being held in proper position during the folding operation. First the side wall section3 will be moved to bring cleat II above the projecting cleat ends and 52 so that the cleats l5 and 23 substantially contact each other laterally with the extending cleat ends 45 and 52 being positioned beneath longitudinal cleat l5. At the same time the top cleat M will be moved substantially into contact with the cleat 34 of the top closure T with the extending cleat ends 40, 4| extending beneath the longitudinal cleat I4 of the side wall section 3.

Continued swinging of side wall section 2 into position toward the bottom and top closures will carry the longitudinal cleat l0 against the cleat 30 of the bottom closure and also position the extending cleat ends and 5| above cleat l0, and at the same time move longitudinal cleat 9 against cleat 36 of the top closure T and carry the extending cleat ends 42 and 43 above longitudinal cleat 9.

Swinging of side wall section 4 toward the bottom closure and the top closure will carry cleat l9 against cleat 3| and at the same time move the extending cleat ends 46 and 41 closely over the top of longitudinal cleat 19 while the top cleat I8 is moving against cleat 35 of the top closure T and the extending cleat ends 38, 39 are moving over and closely against the upper surface of cleat 18 of the side wall section 4.

Finally side wall section I will be swung into position against the bottom closure B and the top closure T with the longitudinal cleat 6 touching against cleat 29 and the top longitudinal cleat 5 touching against cleat 33, while the extending cleat ends 58 and 45 will be below and in contact with cleat ii and the extending cleat ends 31 and M will be below and in contact with cleat 5. The loops 24 and 26 are then pushed through loops 25 and 27 and bent backwardly a desired amount, upon which the closing of the container is completed.

Fig. 6 shows this closing operation (the bottom closure B being omitted for the sake of clarity) nearly completed around the top closure T, while Fig. '7 shows the upper corner of the container at the meeting ends of the wirebound mat forming the side walls nearly closed, while Fig. 8 shows the latter mentioned parts closed and fastened together by the bending of the loop 24 through loop 25, it being understood that during this fastening action loop 25 will be passed through loop 21 and bent over the same as described earlier herein.

With the closing of the container walls and top and bottom closures completed as described above, it will be seen that I have provided a container in which the longitudinal cleats of the side wall sections which form a wirebound mat are laterally offset with relation to each other, and the projecting ends of one set of the parallel cleats of each of the top and bottom closures are above two of the longitudinal cleats of the opposite side walls, while the ends of the other set of parallel cleats of both the top and bottom closures are below the longitudinal cleats oi ,are not necessary to hold the ends in position,

any nailing that might be suggested being used only when the container is expected to support heavy loads, such nailing being for the purpose of providing resistance to weaving but is not necessary to the main lock-in feature of .this invention.

It will be understood that the shape and size of the container will be such as to accommodate various sizes and shapes of articles to be shipped, and while I have-shown for illustrative purposes the container as having four side walls it will, oi course. be understood that any other number of side walls could be used where the same would suit the shape and size of the article to be shipped. v This gives an eilective interlocking oi the top and bottom end closures without necessity of complicated structural parts, and at the same time such end closures arevery strongly connected to the side wall sections without the necessity of nails, screws or the like. I

If the container is used for shipping articles of undue weight the meeting cleats oi the top and bottom closures can, if desired, be further fastened together by additional fastening means such as nails, screws, bolts or the like, where such additional strength is deemed necessary. In the majority of instances, however, such rastening by nails, screws or the like will not be necessary and is only advised in extreme cases, which would be the exception to the rule. Also the angular disposition of the binding wire at the folding edges oi the side wall sections will provide sufilcient strength to eiiectively hold these parts together, and at the same time enable the wrapping of the side wall sections around the top and bottom end closures and the article to be shipped when closing the container.

If desired, the extending ends 46, 61, 50 and E3! of the bottom closure B may be omitted and the sides folded around the top closure, as de scribed earlier herein, and fastened thereto by bending the ends of the wires, after which the completely folded mat with the top closure locked in position may be lowered over the article to be shipped fastened on the bottom closure, after which the bottom cleats of the. sides may be secmeiy nailed to the bottom closure.

Having now described my invention,
