FOLDING BOX OB SHIPPING-CASE.

14,471. Specification of Reissued Letters Patent. Reissued May 14, 1918.

Original No. Ml,013, dated November 23, 1900, Serial No. 448,642, filed August 16, 1908. Application for reissue filed February 23,

To all whom it may concern:

Be it known that William H. Doble, a citizen of the United States, residing at Quincy, in the county of Norfolk, State of 5 Massachusetts, and Carl M. Wheaton, deceased, a citizen of the United States, late of Newton, county of Middlesex, and State of Massachusetts, did invent a certain new and useful Improvement in Folding Boxes or 10 Shipping-Cases, of which the following is a specification, reference being had therein to the accompanying drawings.

The special object of the invention is to provide a folding box of sufficient size and 16 strength to serve as a shipping case in which goods may be packed for shipping and the goods be protected against damage by breaking of the case while being handled and which can be folded into small compass to 20 be returned to the shipper. The box is of rectangular form having as usual a bottom, two sides, two ends and a cover, all of which members are adapted to be hinged together, and preferably are divided into sets of three 26 members each ; that is preferably one set of three of said members are hinged together, another set of three members are hinged together, and the two sets thus formed are adapted to be hinged together by a draw SO hinge when they are set up and are adapted to be separated from each other so that when the box is knocked down, each set may be folded by itself. Preferably also each of said members, that is, each of said side and 35 end pieces, and the top and bottom, has an inner and an outer wall with an air space between the walls, said inner and outer walls being held together by strengthening plates or corrugated plates, the inner and 40 outer walls cooperating to help form the hinged joints.

One feature of the invention relates to the form of the corrugated plates which have broad, flat faces. Other features of the in46 vention will be particularly set forth hereinafter.

The invention will be understood from the following description when taken in connection with the accompanying drawings and 60 the novel features thereof will be pointed

out and clearly defined in the claims at the close of this specification.

In the drawings, Figure 1 is a perspective view of a box emoodying the invention, the., cover being shown partially open and the '65 locking rod which locks the cover to the front wall of the box being shown detached.

Fig. 2 is a perspective view of the box partially knocked down, before the two sides are separated from each other and with both 80 of the end walls in a vertical position as before being folded.

Fig. 3 is a perspective view of the bottom, front and one end which constitute one set and are shown in their fully knocked down 66 position, the end member being folded over onto the front member.

Fig. 4 is a perspective view of the cover and back and the other end which constitute the second set, showing them in the knocked 70 down position, the end member folded over onto the back member.

Fig. 5 is a longitudinal vertical section of the box fully set up and the cover closed.

Fig. 6 is a vertical cross section of the box 75 at right angles with the view shown in Fig. 5. / .

Fig. 7 is a section through the hinge connection between the back and bottom when laid out flat as in Fig. 2. 80

Referring to the drawings, the principal members of the box are the front A, the back B, the two ends C and D, the cover E and the bottom F. The front A, the bottom F and the end D are all hinged together and 85 form one set as shown in Fig. 3 when the box is in its knock down form. The back B, cover E and end C are all hinged together and when in their knock down form, form the second set as shown in Fig. 4. The hot- 90 tom F and back B have a draw hinge connection with each other as will be hereinafter described, whereby the two sets may be connected together as-shown in Fig. 2 before the box is set up. Each of the above 95 six members comprises an outer plate and an inner plate with a space between them, and united together by corrugated plates 13 in the space between the outer and inner plates. The front A has an outer plate 1 and an 100

14,471 inner plate 2. The back B has an outer plate rugated plate, and other connectionsare 3 and an inner plate 4. The end C has an made by striking up some of the flat faces outer plate fi anl an inner plate 6. The end b to form eyelets which pass toles

Theeorrugated plates 13 between the walls the inner and outer wall plates which give are corrugated or formed with strut portions great rigidity to the wall of the box and to cross between the inner and outer plates which cannot easily be broken down by and with flat portions which are secured to vibration or shock to the wall plates and which by reason of the broad contact sur- so faces make the wall plates themselves much less liable to be bent or crushed in; by lateral pressure or shocks than if the corrugations were rounded in such manner as to give only a narrow line of contact. 86

Each of the six members A, B, C, D, E and F is formed with rolls or curls on those edges which are shown free in the knock down position of Fig. 2 which are adapted to interlock the rolls or curls in the adjoin- 90 ing free edges of the other members when the six members are set up, the front edge of the cover E and the top edge of the front A being adapted to be fastened together by a removable locking rod or other suitable 95 fastening, as will be hereinafter described.

The front edge of the outer plate 11 of the bottom F is formed with a series of curled fingers or knuckles 15 and the inner plate 12 of the bottom is formed with a cor- 100 responding series of ciiris or knuckles 16 which are curled inside of the knuckles 15. The outer· plate 1 of the front A is formed on its lower edge with a series of curled fingers or knuckles 17 and the inner plate 106 2 of the front is formed with a corresponding series of curls or knuckles 18 which fit inside of the knuckles 17, the knuckles 17, 18, being adapted to fit into the spaces between the knuckles 15, 16, of the bottom as 110 shown in Fig. 1. A rod 19 passes through the knuckles of the front A and bottom F to fasten them together as shown in Figs. 1 and 6. This rod 19 is preferably secured against withdrawal in any suitable manner, 115 preferably by making it fast or fitting tight within the knuckles 16, the knuckles 18 being sufficiently loose on the rod so that the front A may be turned down on the rod as a pivot to bring the front down flat in plane with the bottom F as shown in Fig. 2 when the box is knocked down.

The left hand ends of the plates 1, 2, which form the front A, as viewed in Fig. 1, to which the end D is connected, are formed with inward curls, respectively, the curl of the inner plate being inside of the curl 21 of the outer plate, and being curled around the stiffening rod 22. These curls are formed with a series of elongated slots

1ft the inner and outer plates by suitable fastening means.

The corrugated plates 18 are formed with broad flat faced portions a at intervals apart in the same plane with each other which con20 tact with the flat outer wall plate and are secured thereto, and are formed with broad flat faced portions b at intervals apart in thp. sums plane with each other which contact with the flat inner wall plate and are 26 secured thereto. The flat portions a are parallel with the flat portions b and alternate therewith. The flat portions a are connected with the adjacent flat portions b by transverse strut portions c which extend 30 crosswise of the space between the inner and outer wall plates. Thus between each pair of inner and outer wall plates there is a corrugated plate having flat faced portions which alternately contact with the inner and 36 outer wall plates and are secured thereto and are connected together by strut portions.

Preferably the planes of the strut portions c are at an obtuse angle to the plaiies of the strut portions a ana b, and prefer40 ably also the comers d formed at the bends in the corrugated plate at the juncture of the flat faces a and b with the stmt portions c are all abrupt turns as such a construction not only makes a broader contact of the 46 surfaces a and b with the outer and inner wall plates than if the comers of the edges of the flat faces were rounded, but it also makes the entire wall more rigid.

The plane of each strut portion is at an 60 angle to the plane of each adjacent strut {>ortion viewed in one direction, but the ongitudinal direction of all of the strut portions of each corrugated plate are parallel with each other.

These corrugated plates are firmly secured to the inner and outer wall plates by any suitable means so that there shall be.no creeping. Any suitable means of securing them may be employed. The means shown 60 consists of eyelets 14 struck up from the outer plate and from the flat faces of the corrugated plate, that is some of the connections are made by striking up the outer wall plate to form eyelets which pass 66 through holes in the flat faces a of the cor120

12ft

14,471 passing through the curls of both plates. The lower edges of the inner and outer plates 7, 8 of the end wall D are formed respectively with the curled tongues 24, 25 as shown in Fig. 3, the tongues of the outer plate being curled within the tongues of the inner plate. These tongues pass through the slots 23 and hook around the curl 21, thus forming a pivotal connection between the end D and the front A.

One edge of both the inner and outer plates of the bottom F is curled, one within the other, forming a roll 26, curled around the stiffening rod 27, and the cooperating edges of the outer and inner plates of the end D are curled, one within the other, forming a double lip 28 which is adapted to engage the curled roll 26 of the bottom when the box is set up.

The left hand end of both the inner and outer plates of the back B form a curled roll 29 around a' stiffening rod 30 and the cooperating edges of the inner' and outer plates of the end D are formed with a double curled lip 31 which is adapted to engage with the curled roll 29 when the box is set up.

The end C is connected with the back B in similar manner to that in which the end D is connected with the front A. The edges of the two plates 3 and 4 of the back are formed with a curled roll, one within the other, forming a curl 32 around- the stiffening rod 33. The roll 32 is formed with a series of elongated slots similar to the slots 23 in the roll 21 of the front to which the end D is connected. The inner and outer plates 5, 6, of the end C are formed with curled tongues, one within the other, forming a series of tongues 34 which curl around the roll 32 and engage with the slots in the roll 32 when the end C is folded down over the back B as shown in Fig. 4.

The cover E and the back B have a hinge connection with each other. The inner and outer plates of the back B are formed with outwardly curled rolls 35, 36 the curl of the outer plate being curled within the curl 35 of the inner plate around the stiffening rod 37. The inner and outer plates 10, 9 of the cover are formed respectively with the curled tongues 38, 39 one within the other, which curl around the roll formed by the curl 35, 36 of the back B. The roll formed by the curl 35, 36 is formed with elongated slots 40 through which the tongues of the cover pass when the cover is turned back as shown in Fig. 4.

The bottom F and the back B have a draw-hinge connection with each other. The inner and outer plates 11, 12 of the bottom are drawn together near the edge forming a neck 41 and then are curled around forming an eye 42 which is curled around the rod 43. The neck 41 is provided with a series of elongated slots 44, as shown in Fig. 7.

The outer and inner plates 3, 4 of the back B are drawn together forming a neck 45 and then are spread and turned back upon 70 themselves as shown in Fig. 7, and have a series of projecting portions corresponding in width with the elongated slots 44 which are spread and curled back upon themselves as shown in Figs. 4 and 7 forming a 75 series of open eyes 46 which embrace the roll 42. The space 47 formed between the lids of the eyes 46 is of a width sufficient to permit lateral passage of the neck 41 of the bottom so that when the back and the bot- 80 tom are turned down into the same plane, as shown in Fig. 7, the bottom and the back may be separated from each other by a lateral movement as will be obvious. When they are assembled, however, as shown in 85 Fig. 7, if the back B is turned up at right angles with the bottom, the lids of the eyes 46 will engage with the slots 44 and lock the two members together to prevent lateral disengagement. The portion of the outer 90 plate 3 of the back B between the eyes 46 is turned back to form a clamp 461 which more closely binds together the inner and outer plates and the intermediate corrugated plate as shown in Fig. 4. 95

The end C and the bottom F are constructed in such manner that the two may be engaged and the box set up in similar manner to the engagement of the end D and bottom F; that is, the inner and outer plates 100 of the bottom are formed with curled edges, one within ^;,the other, forming a roll 48 around a rod 49, see Fig. 3, which is adapted to be engaged by the outwardly curled lip 50 formed by the edges of the inner and 105 outer plates of the end C.

The end C and front A are adapted also to be connected in a similar manner as the end C and the bottom F and the inner and outer plates of the front A are formed with no a roll 51 around the rod 52 which is adapted to be engaged by the curled lip 53 formed on the edges of the inner and outer plates of the end C.

The cover E is formed on one edge with 115 a roll 54 made by the edges of the outer and inner plates 9, 10 curled around the rod 541 which is adapted to engage with an outwardly curled lip 55 on one edge of the end D formed by the combined edges of the 120 outer and inner plates 7, 8, and the cover E is also formed with a roll 56 around the rod 561 on the opposite edge froin the roll 54 which is adapted to engage with a curled lip 57 formed by the combined edges of the 125 outer and inner plates of the end C. When the box is set up, and the cover is closed, the rolls 54, 56, can easily be sprung into engagement with the lips 55 and 57, respectively, of the ends D and C. 131

Any other suitable locking mechanism may be provided. .

on Assuming the box to be in its knocked down form, the set comprising the cover, the back and the end C are folded as shown in Fig. 4, the end being folded over onto the back, and the set comprising the front, the bottom and the end D are folded as shown in Fig. 8, the end D being folded onto the front A. In order to. set up the box, the two sets are first joined together by engaging the two members of the draw hinge with each other; that is, by engaging the roll 42 of the bottom with the eyes 46 of the back B by a lateral sliding movement ; then the two ends C and D are turned up into a vertical position as shown in Fig. 2. The front

A may then be turned up into a vertical position, thereby also turning the end D on edge endwise through ninety degrees, so that the lip 28 may be sprung into engagement with flie roll 26 on the bottom F. The back

B may then be turned up so that the lip 31 of the end D may be sprung into engagement with the roll 29 of the back and in turning up the back B, the end C will also be turned edgewise so as to bring the lip

50 to the bottom where it may be sprung into engagement with the roll 48 of the bottom F and the lip 53 of the end C may be an w- h„_{ing siI}.,,
