and in France January 14, 1930:

' 2 Claims. (01. 217-12) Types cf packing cases are already known which can be quickly and easily dismantled and reassembled as many times as may be desired without any risk of seing damaged or destroyed 5 for a long time, the assembfing of the panels of such cases hein erfected without the use of nails.

In certain of these cases, the panels engage With one another by means of grooves pr0vided along the edges of certain panels and With which These grooves may ce consticuied for instance by rods held at a certain distance from the edges of the panels.

b the edges 01" the adjoining panels engage.

When the various panels are engaged with one another, they are held assembled a rule by putting one or more wires round the case thus constituted.

When the case is dismantled, the various panels of the same can be stacked on one another.

The present invention relates to a case, the various panels of which can also be assembled together and enee the case is dismant led can be But in this type of case that can be dismantled, the various panels are assembled together by means of projecting tenons provided on the edges of the panels, in the plane of the latter, and engaging with morstacked on one another.

tises provide in the adicining panels,

Each tenon ce constituted by a projection made out of the material or the panel or secured to it, and reinforced outside preferably means of a fitting constituted for instance by stamped ont metal plate, tire tsothed badges of which engage With tl e Each mort e may be constituted by a recess panel.

provided in the edge of the panel and trimmed or covered outside preferab1y by means of a fi* ting firmly secured to the said panel.

The fitting in question may ne constituted by a simple sheet or band of metal held by means cf clips or fasteners secured t0 the panel.

may be ccn "tuted also by a piece of metal, the

ends of wnien given a suitable shape and stamped with the panel,

; out, have toothed or serrated edges engaging way limitative.

In the said drawings:

Figure 1 s 1ews in erspective the various panels of the case separately.

Figure 2 shows in perspective the assembled case.

Figure 3 'is a perspective view ofa mortise With.

its fitting.

Figure 4 is 9. section of a tenon engaging with its mortisa.

Figures 5 and 6 are two Hxodified constructions of mortise and tenon. A

The case comprises a bottcm 1 and four sides 2 (equal or unequal in tw0s) each constituted for instance by WoOden boards or planks joined togetber by bars 3. A cover 4 also constituted for instance by boards or planks connected together loy bars 5, engages With the case thus constituted, between the projecuing portions of the bars 3 of the lateral panels.

In the bOttom edge of each of the large sides 2 is provided a mortise 6 trirnmed or c0vered outside by a hcop iron 7, the widened ends of which are turned over and provided with teeth 8 which engage with the wood of the panel 2. Into each of these mortises 6 thus trimmed with a metal band securely fixed to the side 2 of the case, can penetrate a tenon 9 secured to the bottom 1 of the latter and reinforced by a stampe ont piece of sheet metal 10, the turned clown edges of which are also provided With teeth 11 which engage With the wood of the bottom 1.

In the same way, the small sides 2 of the case comprise each three mortises 6 with which engage tenons similar to the tenons 9 and secured to the bottom land to the large sides 2 or the case.

The tenons 9, instead of being constituted by a projecting portion of the edge of the board strengthemed subsequently by a piece of metal sheet, may be constituted also (Figure 6) by a puton key 12 of wood or other material held in place by a metal clip 13 with toothed edges driven into the walls of the W0Od of the panel.

In the same way, the mortises 6 could be trimmed with a piece of h'oop iron 14 (Figure 5) held in place at its ends by put-on metal brackets or clips 15 with toothed edges engagng With the wood.

It goes without saying that instead of providing on each edge of the bottom or of the sides of the case, only one tenon or only one mortise, it is possible to provide several -of them arranged one behind another. 4 7

In the same way, the sides of the case may comprise tenons exigaging wth mortises in the bottom and/or in the other sides.

Instead of providing metal covering only at the point -of the tenons and of the mortaises, such coverings could be provided also all round each of the panels of the case so as to give greater strength to the latter.

According to the thickness of the wood panels constituting the sides of the case, the teeth of the parts 7, 10, 13, 15 may be made of a correspondingly greater or smaller length.

The method of assembling the case will be readily understood.

First take the bottom 1 and put in place successively each of the sides 2 introducing the ten- 0115 9 of the bottom and of the sides into the corresponding mortises 6 of the opposite panels. This having been done, assemble the whole for instance by means of pieces of hoop iron or of iron Wires 16 passed preferably into the mortises 6, against the inner wall of the hoop irons 7 used for the trimming. The number of the assembling hoop irons or wires thus utilized may vary atv W111. These hoop irons or wires are finally tightened and secured to the panels by any desired well known means. Once the case has been filled, it is merely neeessary to put in place the cover which may also be secured by means of hoop irons or iron wires 17 or in some other manner.

To dismantle the case, it is sufficient to out; the wires or hoop irons which hold the panels together whereupon the latter can be easily detached from one another and stored with the panels of ocher cases in a limited space by superposing them or simply placing them side by side.

It will be seen that these cases which do not comprise any aSsembling by nails, W111 mot deteriorate during their successive dismantling and reassembling, so that they have a long life.

It will be understood that this case may be made of any desired size and if desired of materials other than wood.

I claim:

1. In a case, a plurality of detachable wood panels forming the sides and bottoms of said case, some of said panels provided With tenons and adjacent panels having cooperating mortises, the mortises being constituted each by a notch made in the edge of the panel and closed by a metallic strip going deep into the wood at its ends beyond the ends of the notch, the breadth of the notches being equal to the thickness of the panels.

2. In a case, a plurality of detachable wood panels forming the sides and bottoms of the case, some of said panels provided With tenons and adjacent panels having cooperating mortises, the mortises being constituted each by a notoh made in the edge of the panel and closed by a metallic strip secured to said edge at its ends by teeth going into the wood at a distance from the edge, the breadth of the notches beng equal to the thickness of the panel.
