BOX.

Application led July 26,

and, of course, varying in weight in accord# ance with the size of the box and the -purpose to which it lis to be put in use, and the present invention has more particularly in view the means for locking the sections of 16 such a box together in assembled relation and means for maintaining said locking or interengaging means in operative position.

Boxes of this type have given excellent results, but the added material, labor and 20 waste involved in affixing or providing a locking flange on the inner face of the upper part of the lip D of the bottom end section C has involved considerable expense in the total, as has also the provisionof asimilar .:5 cooperating Aflange, on the outer face of the lower portion of the body section B, considered on a large quantity production basis.

The objects of the presentninv'ention are to provide a box of the above type of a particular construction, preferably paper covered, in which the locking flange or element or tongues 1 on the body section may be stamped out from the body member and will cooperate with sockets, recesses or holes stamped out of the paper board or card board material of the lip D to form the locking or interengaging means between the two sections, the locking flange above mentioned and heretofore provided on the upper portion of the innerA face of the lip D being l`dispensed, with.

Further objects are to so relate the parts that with any particular weight of material, and corresponding width of locking tongues 1 and corresponding width of co` operating locking sockets, recesses or holes 3, one portion 2 of the edge wall of each of the latter will engage with the upper free side edge face of its respective tongue, and an opposite edge portion 4 of said socket, recess or hole 3 will engage its respective tongue 1 at such point intermediate the sides of said tongue 1 as to act asv a brace to maintain said tongue in correct position, as above p5 mentioned, in assembled relation` and to prevent said tongue 1 from springing out later- 1924. Serial No. 728,394.

ally beyond the cooperating edge wall portion 2, and to act also as a brace to prevent the deformation of said tongue under strain in normal use, all of which objects, among others, are accomplished by the construction, combination and arrangement of parts, all as hereinafter more particularly set forth, described and claimed.

In the accompanying drawings, representing but two embodiments of my invention merely by way of illustration of the practice thereof:

Figure 1 represents a perspective View of abox embodying my invention and broken away at several points to aid in giving a bet` ter understanding of the details thereof, the paper covering F being omitted for the same reason,

Figure `2, .a detail horizontal sectional view looking downward;

Figure 3, a fragmentary horizontal sectional view, broken away, looking downward and taken through the body section and the lip of the bottom section on a horizontal plane coinciding with the upper side edge faces of the locking tongues in their engaging assembled relation;

Figure 4, a fragmentary perspective sectional view taken on a line corresponding to line 5--5 of Fig. 3, of the body section and the bottom section in superposed relation in an intermediate stage of assembly;

Figure 5, a fragmentary detail perspective View taken on line 5 5 of Figure 3;

Figure 6, a detail cross-sectional view, on an enlarged scale, taken on a line corresponding to line 5 5 of Figure 3; the paper covering F being illustrated on a greatly magnified scale out of proportion to the illustration of the other elements in said view; and

Figure 7, a view similar to Fig. 6, of a modification in which the covering F is omitted.

Referring now in detail to the drawings, A designates the cover or top section of the box, B the body section or ring, and C the bottom end section having an edge flange or lip D.

The body section B as, preferably integral, depending spreading and bracing flanges E having their end edges mitered, said flanges, in the assembled box, lying against the upper face of the bottom end section C substantially at right angles to the sides of said body portion B with their end edges in, 0,?

substantially in, engagement to act as a bracing and spreading device to hold the lower part of the body section spread and prevent its deformation to maintain the locking tongues 1 in such position that their fi'ee upper side edge faces will be in locking posit-ion wit-h relation to the coopera-ting upper downwardly presented, preferably abrupt, edge walls 2 of the corresponding sockets, recesses or holes 3 respectively of the lip D. Of course the exact construction of the flanges E is not essential, their function is to hold the lower end portion of the body section spread and to prevent its deformation and any element or elements accomplishing this purpose are to be considered as equivalents.

The locking tongues 1 are formed by making inverted approximately U-shape cuts in the lower part of the body portion or section B, severing the material thereof on three sides and leaving the tongues 1 integral with the body section, or with the respective bracing and spreading flanges E, along a line preferably coincident, as shown, or substantially coincident, with the line along which the respective spreadingr flanges E fold inward, so that the inward folding of the latter will cause the outward protiusion of said tongues 1, the material of which they are formed and their combination with the respective spreading flanges E resulting in said tongues 1 each being yieldingly resilient and being yieldingly resiliently held or positioned as a whole, so that when the bottom section C is applied its lip D, in engaging with the respective outer faces of the lower portion-of the body section B will engage the lower outer faces of the said locking tongues or small locking flanges 1 and cause them to yieldingly resiliently fold back toward the adjacent face of the respective outer faces of the body section B and back into the openings from which they are respectively cut until the upper walls 2 of the respective sockets, recesses or openings 3 formed in the lip D pass upward far enough to release the respective tongues 1, which will then spring outward, due to their resiliency, until stopped by the inner edge of the lower walls 4, respectively, of the openings v3, when the upper free side edge faces of the respective tongues 1 will be positioned directly beneath and in engagement with, or "ery closely adjacent to, the cooperating reversely presented Walls 2 ofthe respective openings 3, all as is well illustrated in Figures 4, 5 and 6.

Preferably a medium Weight or heavy weight of material will be used to make a stiff box and insure a very strong positive lock or engagement between the box sections,

so that the box may be relied upon for use in connection with heavy .silver ware, cutglass, fancy china and the like.

Lesaiez There is an important relation between the weight and stiffness of material used, the width of the locking tongues and the width and location, in a vertical direction', of the sockets, recesses, or openings 3 in the lip D, and this is especially so where a covering paper F is not employed, in order that the respective tongues 1 may be limited in laterally outward swinging movement in assembling, so that their upper side edge faces will not pass outward beyond the vertical plane of the cooperating upper walls 2 of the respective sockets, rec sses or openings 3, and so that said tongues 1, when under stress, will be braced and in effect shortened in length so that buckling will -be prevented in any normal use, having in view of course the use the boxes are to be put to.

This relation must, of necessity, vary in accordance with the weight of board material and width of the tongues 1 and height of the lip D, but should be suc-h, as illustrated, as will permitv the respective tongues 1 to spring out to an extreme outward position wherein their free upper side edge faces will lie approximately fully in the same vertical plane with the cooperating walls 2 respectively, and so that the inner edges of the lower walls 4 respectively will prevent any further outward swinging movement as a whole of the respective tongues 1.

The bottom section C will preferably be covered with a finishing covering F, which may be, and usually is, of paper, as is usual in boxes commonly known as papered oreovered, and the body section and top will also preferably be papered to match.

The covering F on the bottom section C,

in addition to serving its usual function, also serves to hide from view the openings 3 and the tongues 1 therein and, being unifoinity pasted over the area of' the bottoni end scction C and its lip D, will also serve to aid in preventing the respective tongues 1 from protruding laterally, so that with the vpaper or other usual covering F a stronger interengaging or interlocking construction can be obtained with a gl ven weight of material, since the paper also adds its strength to resisting any lateral displacement, ensuring that any strain or pull will be exerted edgewise or substantially edgewise of the material of the interlocking parts.

In the modification illustrated in Figure 7 the paper or other covering F is omitted. Otherwise the construction and `operation are the same as in the preferred form. n this modification the importance of maintaining tlie correct relation between the width of the tongues land the width and vertical position of the cooperating sockets, recess or holes 3, and the weight of niatcrial employed, is more accentuated, since there is no additional element to be "relied upon to prevent lateral displacement or IniS- alignment of parts. Also, where the paper covering F is omitted, as illustrated in Fig. 7, a stiff fairly heavy material should preferably be used.

Of course the number and location of the tongues and sockets should be the same on each side, where a perfectly square box is involved, or where an octagonal, pentagonal etc., form box is involved, or on opposite sides where an irregular shape box is in-l volved, and the number of tongues and cooperating sockets, while governed to an extent by the cross-sectional size of the box, may be varied within reasonable limits according to the preference of the manufacturer or particular trade or individual customer.

In the drawing quadrilateral sockets, recesses or holes 3 and cooperating tongues l have been illustrated, but the shape shown is not essential, any shape suitable to the purpose may be employed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A receptacle comprising two paper board sections, one of said sections bepng provided with integral resilient tongues having abrupt free faces, and the other yofsaid sections beingformed With cooperating sockets having upper and lower edges, and means for holding said sections spread and resisting their deformation to maintain said tongues and sockets respectively, in correct, cooperating, interlocking relation, said tongues, in the assembled relation of the parts, extending at an inclination into the respectivesockets, and each said tongue engaging with its freeedge face the opposed upper edge of its cooperating socket and engaging with its laterally outer face the lower edge of said socket, at a point intermediate its point of connection to its corresponding section and its free edge face, to limit its latsaid tongues to an inclined angle of engagement with the upper edges respectively of said sockets, and to brace each of said tongues at a point intermediate its point of connection to its corresponding section and its free edge face. to prevent strain and buckling v under load.

3. A paper board receptacle comprising a body section, means for maintaining it in spread relation and resisting its deforma- Jcion, an end section having a lip adapted to receive the lower end portion of said body section, and interengaging means for locking said sections together in normal assembled relation, said means comprising a plurality of resilient tongues integrally formed on one of said sections, each of said tongues having a free edge, means for presenting said tongues at an angle of inclination for engagement with a plurality of sockets of corresponding size and shape stamped out of the other of said sections, and means for bracing each of said tongues at said angle of inclination, at a .point intermediate its point of connection to its corresponding section and its free edge.

In testimony whereof, I have signed my name to this specification at Washington, D. C., this 26th day of July, 1924.

JOSEPH G. HUYE.
