CHARLES C. MENGEL, OF LO'UISVILLE, KENTUCKY.

KNOCKDOWN BOX.

To oZZ whom it may concern:

Be it known that I, CHARLES C. MENGEL,

a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Knockdown Boxes, of which the following is a specification.

My present invention relates to improvements in knock-down boxes, the construction and advantages of which will be hereinafter set forth, reference being had to the annexed drawings, wherein:

Figure l is a perspective view of the box in a partly assembled condition; Fig. 2 a perspective view of the box when assembled and looked; Fig. 3 a horizontal sectional view, taken through the middle portion of the box; Fig. 4 a vertical sectional view; Fig. 5 a detail section, showing the side members of the box and a portion of the metallic binding and retaining strip; and Fig. 6 a perspective view of said strip, partly folded or brought to form.

The main object of the present invention is to provide a simple, light and durable packing-box, which may be readily assembled and as readily knocked down for the purpose of reshipment.

The construction is such as to permit the employment of thin lumber and, more particularly, composite veneer in the manufacture of the boxes.

The structure may be said to comprise a top, back, bottom and front, connected to each other by two strips of sheet metal of right-angle form, which are secured to the outer ends of said members and spaced away therefrom so as to leave grooves orv channels for the reception of the heads, which fit into the grooves and overlap the ends of the top, back, bottom and front. Said top, back, bottom and front, or as they may be termed the sides of the box, are preferably connected by sheet metal staples or hinge members, in addition to the hinges formed by the metallic strips. The strips will be made longer than just necessary to pass around the box, so as to provide normally free extensions which may be folded down in front of the box and there secured, thus retaining the top in position. In addition to these extensions, independent fastening devices may be employed to hold the top in position.

Referring to the drawings, 1 denotes the Specification of Letters Patent.

top, 2 the back, 3 the bottom and 4 the front of the box. The heads are designated' by 5 and 6 and as illustrated will preferably be formed of veneer lumber. The proximate edges of the top and back, the back and bottom and the bottom and front are preferably beveled and secured by suitable sheetmetal staples 7, which as will be noted upon reference to Fig. Ll, are driven through the sides and clenched. The four side members are thus secured together, and to the members thus held there is fastened at each end thereof a sheet-metal binding strip S, of L- shape in cross-section. The strip or binding member is of a length greater than the aggregate length necessary to pass about the box, so that it Will form a tongue or projecting member 9. The strip is notched, as at 10, and the notched sections are bent up at right angles to the main body of the strip so that when the strip is secured to the box it may be folded up with the sides, the notched portions overlapping, as clearly indicated in Figs. 1, 2 and 5. Said strip is secured to the sides so as to form a channel or groove 11, as shown in Fig. 5, adjacent to the ends of the sides, into which groove or channel is fitted a head, the'head being of such thickness as to completely fill the groove when the parts are brought to their assembled position, as in Fig. 2. The strip being formed of malleable sheet-metal, the box may be opened-and closed a number of times before the parts break at the corners of the box, or where the body of the strip is bent at right angles upon itself, as at 12.

In addition to the tongues or projections 9 formed upon the strip and which, as before stated, may be employed to secure the box lin its closed position, by means of small nails or the like, as at 13, Fig. 2, I may employ suitable fastenings, as shown in Fi gs. 1, 2 and 4, said fastenings comprising two sheet-metal members 14 and 15, secured, respectively, to the top and front of the box and adapted to form an interlocking connection with each other When the box is fully closed. Such fastening is shown and claimed in United States Letters Patent No. 915,045, granted to Robert Schleicher under date of March 9, 1909. Any suitable fastening may be employed in lieu of this particular form, if such fastening be found essential. Where relatively thin lumber is employed in the manufacture of the box, such fastening will preferably be present, inasmuch as the same will tend to bind the proximate edges of the front and top together and hold them in position against warping and accidental displacement.

Any blow to which the package may be subjected will be distributed over the whole surface of the end of the box, inasmuch as the end or head projects outwardly into alinement with the outer face of the sides. The metallic strip holds the head firmly in place and binds the parts closely together.

I am aware that it is not new to employ metallic binding strips and no claim is made broadly to such construction. The edges of the various parts will likewise be fully protected.

Having thus described my invention, what I claim is:

l. In a knock-down box, the combination of a plurality of sides; means for securing the proximate edges of said sides to each other; a malleable sheet-metal strip, rightangled in cross-section, secured to each end of the members thus connected, said strips being spaced away from the ends to form channels or grooves; and heads seated in the grooves and abutting against the ends of the box-sides and lilrewise bearing at their edges and outer faces, adjacent to the edges, against the metal strips.

2. In a knock-down box, the combination of a plurality of sides; a continuous sheetmetal member, L-shaped in cross-section, secured to each end of said sides, said sheetmetal members being spaced away from the ends to which they are secured, thereby forming grooves or channels; heads seated in the grooves and abutting against the ends of the box sides and likewise bearing' at their edges and outer faces, adjacent to the edges,

'against the metal members, and means for securing the box in its closed position.

3. In a knock-down box, the combination of a top, back, bottom and front, forming the sides of the box; sheet-metal members, L-shaped in cross-section, secured to the outer faces of the sides adjacent to their ends and spaced' away from the ends so as to form grooves or channels, each of said members being likewise provided With a ltongue or projection adapted to overlap the face of the adjacent box-side; and heads mounted in the grooves and bearing against the ends of the box sides, and -likewise bearing at their edges and outer faces, adjacent to the edges, against the metal members.

4. -In a knock-down box, the combination of a plurality of sides; suitable flexible means for Securing the proximate sides to each other; sheet-metal strips secured to the outer faces of the sides, one adjacent to each end of the sides, said strips being L-shaped in cross-section and spaced away from the ends so as to form grooves or channels adjacent thereto; heads mounted in said groovesor channels; a tongue or projection extending outwardly from one end of each of said metallic strips and adapted to overlap the front of the box and to be secured thereto; and suitable fastening members for securing the proximate edges of the front and top to each other.

In testimony whereof I have signed my name to this specification in the presence of two subscribingwitnesses.
