DEFIANCE PRESSED STEEL COM SIGNOR, BY MESNE ASSIGNMENTS, TO THE PANY, A CORPORATION OF OHIO.

METAL BOX.

Application filed July 13, 1907.

T0 (ZZZ whom it may concern:

Be it known that I, GOTTLIEB KLENK, a citizen of the United States, residing at Defiance, in the county of Defiance and State of Ohio, have invented certain new and useful Improvements in Metal Boxes, of which the following is a specification.

This invention relates to improvements in sheet metal boxes and more especially to improvements in skids for the bottoms of boxes of this type, the same being constructed in such manner as to ofi er substantial reinforcement.

The invention also relates to the specific details of construction and arrangement of parts, which will be hereinafter described and particularly pointed out in the claims.

In the drawings-Figure 1 is a perspective view of my improved box looking from the underside. Fig. 2 is a detail bottom plan view of one corner of the box. Fig. 3 is an enlar ed fragmentary cross sectional view taken on a transverse line through the bottom of the box. Fig. 4 is a detail perspective view of one corner of the bottom of a box. Fig. 5 is a detail view of one of the bottom reinforcing strips in blank form. Fig. 6 is a detail perspective view of a portion of the bottom section and a skid. Fig. 7 is a detail perspective view of a portion of said bottom. Fig. 8 is a perspective view of a portion of a solid bottom section, and a skid. Fig. 9 is a similar view of said bottom to illustrate particularly the tongues. Fig. 10 is a detail transverse section on the line 1010, Fig. 11. Fig. 11 is a detail perspective view of a portion of the bottom shown in Figs. 1 and 2, but showing a slightly dilferent form of applying the tongues. F 12 is a detail section on the line 1212, Fig. 11. Fig. 13 is a detail section on the line 13-13, of Fig. 8.

The numeral 1, indicates side sections, and 2, end sections of my improved box. The end and side sections are folded upon each other to provide substantial corner seams 3. The top edges of said sections are also beaded to inclose a reinforcing element 4.

The numeral 5, indicates a bottom section, provided with a series of openings 6, for the passage of dirt, etc, whereby the box can be readily cleaned and kept perfectly sanitary, and for further preventing of the utilization of the box for other than the purpose for which it was designed. The bot- Specification of Letters Patent.

Patented May 18, 1915. Serial No. 383,642.

tom section is preferably formed from a single sheet of metal, having its edges crimped with the side and end sections, to hold the box securely together. Fitting against the underside of the bottom section adjacent all four sides, are reinforcing strips 7, having their edges also crimped with the sides, ends and bottom to provide a supporting flange 8, as shown in Fig. 3. The inner end of each strip 7, is formed into a bead, and passing through said beads is a reinforcing element 9, thereby providing a flange 10. This flange extends across the bottom of the box near each of its lower edges and is spaced from the outer marginal edges of the box, to afford means for convenient stacking.

The flange 10, which is of a rectangular configuration, provides an elongated bearing or floor engaging surface. The rest between this flange and the extreme outer marginal edges of the bottom of the box is adapted to engage the upper edges of a box below, when several boxes are stacked one upon the other, and the flanges 10 not only act as floor engaging surfaces under ordinary circumstances, but also serve to prevent lateral dis placement of the boxes when they are stacked.

The detail construction of the formation of the flanges 8 and 10, at the bottom of the box forms no specific part of this invention, the same being shown and described in my Patent No. 818,976, February 27, 1906, reissured April 7, 1908, as No. 12,775. I do, however, believe that this feature, in combination with skids and the particular form of reinforcin strips which T will now proceed to describe, is new in the art.

The strips 7, extending lengthwise of the bottom of the box adjacent the side edges, have extensions 11, as shown in Figs. 2 and 5, while the strips extending along the ends of the bottom are out 01f straight at their ends. The extensions 11, project from the end of the flange 10, to the outer edge of the box, to rigidly and substantially brace the corners to resist the downward strain, and at the same time assist in tightly tying the flanges 8 and 10, together.

The skids 12, each consist of side wings 13-13, and a centrally disposed downwardly extended bulged portion 1 1, the bottom of which is on a plane with the bottom of the flange 10. The skids may be applied V to add .latter, is resisted, which greatly tends to,

' use.

7 solid bottom.

to bottoms provided with the openings 6, or they may be used in connection with a The skids may be secured in any of several ways. As shown in Figs. 1, 2, 6 and 7, adjacent the openings 6, are tongues 15, stamped from the bottom sec-. tion and bent over on themselves to engage the wings 13 When the bottom is solid, however,'l prefer to stamp thetongues 15 from the metal, as shown in Figs. 8 and 9, and confine the wings 13 between them and the bottom. When using this construction, the tongues 15 are crimped, with considerable pressure, which forces, the wings 13; in the openings 16 as indicated in Figs. 8. and 13. The. wings are thus recessed at inter vals, as at 16.1 6,to receive the tongues'l5". The depth of this recess is such that the recessedportions of the wing. areheld in a position of exact alinement with the sheet metal of the box bottom. the recessed parts. of the wings 13 lie in the same horizontal plane with the. sheet metal of the bottom, the. plane of the upper face of the: recessed portions being coincident with the plane of the upper face of the sheet metal of the bottom so that a smooth uninterrupted surface is provided on the inner side of the box bottom which will not catch particles of rubbish, or furnish a lodgment, for dirt. This arrangement provides a bite and prevents lateral displacement of the skids, and lessliability of loosejoints. When using the form of tongues shown in Figs. 6 and 8, it is evident that the interior of the bottom will be smooth, which under certain circumstancesis preferable.

If desired the tongues may be made from separate pieces, as indicated in Figs. 10, 11 and 12. The tongues are here indicated at 1d", and consist of strips of metal bent around the'necks formed between openings 6, the; ends 15 fitting in openings 6, and

engaging the under sides of the wings 13.

-Obviously this construction performs the same result as that heretofore noted. The skids when secured in place by the tongues, are of such length that their ends abut against the flanges 10, which construction, coupled with the clamping action of the tongues, prevents the, skids becoming laterally displaced, and at the same time serves strength to the bottom of the box. The peculiar arrangement of the flange 10, forms an important combination with the skids, in that the endwise thrust of the prevent the joints becoming loose when in Forwere it not for this strong and substantial flange the wings would in a short timework from underthe tongues.

The invention as described is extremely simple, and is effective'to accomplish the desired result. The skids must be secured rigidly to the box, to withstand the rough shorter than the distance :extend up to and In other words,

abutting the respective flanges,

yond the bottom of other without the possibility of lateral dis- I placement, of any one of the pile and, at the each of the boxes can be used same time, upon a conveyer consisting of a succession of rollers. When thus used, the skid serves to prevent the end flanges. 10 from dropping between rollers if thevv rollers are between the side fact that these skids abut against the end flanges 10 not only insures a correct en gagement of the box with the conveyer rollers, but also strengthens the end flanges by acting as a strt between them. Furthermore, the skid, having its lower face flush with thelOT/Ver face of the flanges 10, furfl ng 10;. a d e.

nishes additional floor engaging area which will prevent the boxes from; moving too freely upon a flat surface. The presence of the depending stacking flange 10 makes it desirable to equip, the box wi h this additional friction bearing surface. 7 I

the box.

A metal box having a bottom formed with projecting tongues, and a skid adapted to be held between the tongues and box bottom, said tongues being crimped into. the material of the skid to oflset those portions of the skid engaged by the tongue, whereby said tongues interlock with the. skid and the engaging portionsof the skid lie in the 95. the bottom of the box which consists of the a part of the supporting depth besame horizontal plane with the sheet metal of the bottom.

I. A metal box having a bottom formed with projecting tongues, and a skid having wings to be engaged between the tongues and box bottom, the tongues being crimped into the wings to form tongue-receiving re cesses in said wings and to cause the tongue engaging parts of the skids to lie in the same horizontal plane with the sheet metal of the bottom.

5. A metal box bottom formed with tongues struck from the material of the bottom, and a skid having laterally-projecting wings to be engaged between the tongues and box-bottom, the tongues being crimped into the wings to form tongue-receiving re cesses therein and to cause the tongue engaging parts of the skids to lie in the same horizontal plane with the sheet metal of the bottom.

6. The combination in a metal box, with a sheet metal bottom formed with depressed tongues struck from it, of a U-shaped skid provided with wings 13 abutting against the lower face of the bottom and bent at intervals to rest on top of said tongues and in the plane of the sheet metal of the bottom.

7. In a rectangular sheet metal box, the combination of a supporting flange at the lower edges of the side and end walls, a stacking flange projecting downward from the bottom of the box and parallel to and inset inward from the four outer edges thereof, and a supplemental flange flush with the said stacking flange, the said supplemental flange extending from one to the other of two parallel parts of the stacking flange and being positioned between the other two parallel parts.

8. In a metal box, a sheet metal bottom, a depending bottom flange, rectangular in configuration and spaced inwardly from the bottom edges so as rest outside of the flange, a separate U- shaped skid lying generally in the plane of said bottom flange and extending from one side of said flange to the side opposite, being flush with said bottom flange and adapted to provide a box supporting runner supplementary to the said bottom flange, to prevent inward bending of the abutting parts of said bottom flange and being secured to the sheet metal of the bottom so as to act as a strengthening rib therefor.

9. In a rectangular metal box, the combination of a sheet metal bottom, a depending stacking flange on the box bottom and around its four edges, and a Ushaped runner or skid having vertical side walls and a relatively broad horizontal bottom wall to provide a stackingflush with the bottom plane of the box supporting flange, this skid or runner being made from sheet metal separate from the bottom but rigidly secured thereto in such position that it extends from one side of the said box supporting flange against which it abuts, up to and against the opposite side of the said box supporting flange.

10. In a sheet metal box the combination of side and end walls suitably secured together, a bottom secured to the side and end walls, a box supporting flange projecting downward from the bottom along lines near the four edges thereof, and a skid struc turally separated from the bottom but secured thereto with its ends abutting against opposite parts of the said flange, the bottom extremities of the flange and of the skid lying in the same horizontal plane.

11. In a sheet metal box the combination of side and end walls suitably secured together, a bottom secured to the side and end walls, a box supporting flange projecting downward from the bottom along lines near the four edges thereof, a skid beneath the bottom with its ends abutting against the opposite parts of the said flange, and sheet metal tongues connected with the bottom and engaging the skid for securing the skid to the bottom.
