KNOCKDOWN BOX.

Specification of Letters Patent.

PatentedMay 5, 1914.

To all whom it may concern Be it known that we, ISAAC NAYLOR and HENRY B. Ruccnns, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Knockdown Boxes, of which the following is a specification.

Our invention relates to improvements in methods of manufacturing boxes and particularly to the style of box made up of more or less flexible material such as pulp board, fiber board and other composition products reinforced at the edges and corners by stifiening members consisting of wooden strips or other rigid members.

The particular object of our invention is to produce a box of simple mechanical construction which can be manufactured with the minimum amount of hand labor through the employment of suitable machinery.

A further object of our invention is to produce a box that can be manufactured and shipped in flat or knocked down form and that will maintain its parts in proper relation for completion so that when received by the user it may be effectively and accurately put together with cheap labor and great rapidity, thus producing a product of economical manufacture.

A still further and important objectof our invention is to produce a box that when completed and filled cannot be opened or have its contents pilfered or tampered with without clearly indicating the fact.

In the accompanying drawing we have illustrated a preferred adaptation of our invention in the following views Figure 1 shows in perspective two of the connected members and the fragment of a third which enter into the formation of our complete box; Fig. 2 shows the sides of the box in their operative or assembled relation without the topin place; Fig. 3 is a cross-section enlarged showing the connection between the flexible material and the stiffening side strips, and-Fig. 4 is an enlarged sectional detail of one of the corners of a box constructed according to our improved method.

Referring to the drawing in detail, 5 represents a sheet of pulp or fiber board of any suitable composition and thickness and of such proportions as are necessary to form the sides of a rectangular box or receptacle. The side edges of this sheet are secured in any suitable manner in grooves 6 which extend longitudinally of wood strips 6 forming cleats rectangular in cross section, as shown in Fig. 3. This method of attaching sheets of fiber or pulp board to corner pieces in manufactured boxes is the subject of a patent and forms no part of our invention. In the manufacture of our improved boxes the strips 6 are attached in the manner de-. scribed t0 the opposite longitudinal edges of a sheet of fiber or pulp board so that they are parallel to each other and the fiat member thus produced is run through a suitable machine which outs transversely away or miters the strips 6 at intervals as shown at 6 These mitered cuts do not extend the entire depth of the strips 6 but leave intact a portion of the wood as clearly shown in Fig. 1. The miter is also cut in steps or zig zag so that the opposed faces at the ends of the strips thus cut will interfit when the strips are arranged at right angles to each other, and produce a substantially closed joint of the form indicated in Figs. 2 and 4. These mitered cuts are formed in the cleat strips at points exactly opposite, and extending between each of the joints thus formed, the sheet of pulp or fiber board is scored or cut partially through in line with the bottom of the mitered cut in the strips 6 as shown at 5 v The structure in the fiat form above de scribed may be sent to the user who, on desiring to construct a box, will fold the sections bounded by the partially separated strips 6 and the scored lines 5*, at right angles to each other, in so doing breaking the fibers of the wood left at the bottom of the joints formedby the rabbeting operations, and thus closing the joints at the ends of the several sections of the strips 6 as clearly disclosed in Fig. 4:. The box is then completed by attaching rigid angular corner strips or battens 7 of wood or other suitable material which fit over the j oints' at the ends of the sections 6 and are nailed thereto, the nails penetrating the fiber 0r pulp and when it becomes hardened after cooling or setting, if any of the corner strips or battens 7 should be removed, some of the sealing compound would be broken away and thus disclose the fact that one of the strips 7 had been removed and the box opened by an unauthorized person, thus constituting a protective means whereby the unlawful tampering with the package or contents may be discovered and possibly,

traced.

In practice we will prefer to leave an end of the sheet of pulp board projecting to form a flange or tongue 5 and the member or section on which this flange left will form the cover of the box and will be the last section to be secured by a corner strip 7. The tongue 5 may be folded within the continguous side of the'box as shown in Fig. 2 or may be folded on the outside provided it does not extend beyond the edges of the corner strip 7 applied at that portion of the receptacle.

The ends 8 of the box are each made of a single piece of the same material from which the sides of the box are formed and are placed in position against the inner faces of the strips 6 when in their folded or completed arrangement. These bottom pieces may be secured in place in any suitable manner and if desired they may be of wood or of heavier material than the sides of the box so as to give the receptacle great rigidity or resistance against crushing strains.

It will be apparent that with a box constructed substantially as above described, it will be practically impossible to detect the joint at which the edge of the cover is found as all corners are completely covered and concealed by the battens 7, hence if any one attempted to get at the contents of the receptacle to pilfer same he would be at a loss to know which of the battens to re move and unless regardless of fear of discovery that the package had been tampered with, might have to remove four battens before he could reach the joint at which the flange or tongue 5 was folded.

As above stated, the removal of a batten 7, even though the nails would be carefully withdrawn by suitable tools, would cause the more or less brittle compound filler 9 to break off and thus disclose to the consignee of the box that it had been tampered with in transit.

In applying the sealing compound it may be permitted to overflow the corner opening formed in the manner provided, and before hardening the surplus compound projecting at the joint formed at the corners may have a suitable seal applied thereto and this seal would be broken by removing any one of the battens 7. The seal arrangement referred to is indicated at 9 in Fig. 2.

Having thus described our invention what we claim as new, is

1. A knock-down box composed of side members of a sheet of flexible and bendable material, and wood cleats secured to the opposite edges of said side members, said cleats being partially cut through at spaced intervals to form mitered and hinged joints, means for securing said side members and cleats in folded relation, and separate end members for said box.

2. In a box, side members of foldable material, and cleats of rigid material secured to the edges of said side members, said cleats being continuous but partially severed at intervals to form mitered and hinged joints at the corners of the box when said sidemem- 'bers are folded, and means for securing said side members and cleats in their folded re lation.

3. A box member consisting of a sheet of pulp or fiber board or similar material having secured to two of its edges continuous rigid strips, said strips partially out through at intervals to provide mitered joints when the cleats thus formed are arranged at right angles to each other.

4. A box consisting of a sheet of pulp or fiber board or similar material having secured to two of its longitudinal edges, continuous strips of wood partially cut through at intervals to form mitered joints, and said pulp or fiber board scored along lines corre sponding to said mitered joints, and means for securing said members in their folded relation to form the sides of a box.

A box consisting of a sheet of flexible material, continuous strips of rigid material secured to the opposite longitudinal edges of the sheet, said strips being partially cut away to form mitered joints when the sections resulting from said cuts are arranged at right angles to each other, battens embracing said sections at their jointed ends and extending from the corners at one end of the box to the corners at the opposite end, and end pieces arranged on the inside of the box and supported by the end strips.

6. In a box, side members consisting of a continuous sheet of suitable material scored at intervals to facilitate bending, cleats secured to said sheet and consisting of continuous strips of suitable material, partially In testimony whereof We affix our signasevered at intervals to facilitate bending, tures in the presence of two Witnesses.
