KN OCKDOWN CONTAINER.

7 Application filed October 27,1926. Serial No. 144,498.

The main object of my invention is to provide a compact, reliable construction which can be economically made and readily assembled.

Another object is to provide a construction which can be knocked down, returned and re-used. Such constructions are not only compact and readily shipped in a knocked down condition at a minimum of expense but also conserve the materials of which the container is made, since the container is durable and can be used over and over again even with ordinary handling.

The invention contemplates the use of parallel staves which are secured together by means of bands orstays in the form of a mat. These bands are not'only nailed or riveted to the staves but are actually interlocked with the staves by being set into grooves in the outer surface so that the staves cannot move lengthwise. The sides of the staves which constitute the inside of the container are grooved to receive the heads and the entire container, when assembled, is held together and reinforced by external hoops in addition to the bands.

In the accompanying drawings I have shown two forms of containers but it should be understood that the proportions and sizes may be varied to suit the requirements of the trade.

Fig. 1 is a perspective view of what would ordinarily be termed a barrel in its assembled condition but without the head.

Fig. 2 is a perspective view of the container in its knocked down or mat-like condition.

Fig. 3 is a longitudinal sectional view of a fragment of one of the staves showing the nail before clinching.

Fig. 4 is a similar view of the opposite end of the stave with a head and band in place and the nail clinched or riveted over.

Fig. 5 is a transverse sectional View showing a plurality of staves laid out flat'and with a fragment of the head in place in one of the staves in the position the parts would occupy when starting to assemble the container.

Fig. 6 is a perspective view of the form.of container commonly termed a cheese box.

Each stave 7 is preferably made of a flat strip of wood of any suitable character. One edge as at 8 is preferably cut at right angles to the outer and inner surface and the other edge as at 9 is bevelled so that when the staves are assembled with the bevelled and right angled edges together, the joints are tight inside and out. The angle of the bevel will depend upon the size of the head 10. Each stave is also provided with a groove 11 to accommodate the edge of the head. This groove is preferably concave on an arc corresponding to the circumference of the head.

Each stave is also grooved on the outside at 12 and 13 preferably nearer the center of the stave than the head grooves. These grooves 12 and 13 are of substantially the same depth and width as the thickness and width of the bands 14 and 15 so that the bands fit in these shallow grooves and their outer surfaces are substantially flush with the outer surfaces of the staves. The bands are secured in place by one or more nails or rivets such as 16 which are driven through and upset, clinched or headed at 17 on the inside. Preferably two nails are driven through each band into each stave so as to more securely hold the parts together and prevent distortion of the mat.

The staves and bands are assembled in the process of manufacture and shipped flat in the form shown in Fig. 2. The user assembles the mats on the bottom head and a hoop 18 is applied around the outer Wall of the container adjacent the bottom head. This hoop is usually applied by means of some suitable form of apparatus by which the hoop is pulled up very tight and then secured in place. When the container is filled the upper head is inserted in the usual manner and another hoop 19 applied around the outer wall of the container adjacent the upper head in the usual manner. After the container has been assembled an additional hoop 20 may be applied around the middle if desired. After the container has been emptied the hoops can be removed, the heads taken out and the body of the container spread out into mat-like form for return or re-shipment.

The interlocking connection between the bands 14 and 15 and the staves gives much greater security to the container in that it practically makes it impossible to loosen the staves by endwise displacement. This interlocking relation also holds the parts more securely when in the spread out or mat condi- I claim;

A knock-down container eon prisin ga se ries of fiat staves, each stave having aconcave groove in its inner face near each end to receive the edges of the heads, and grooves of uniform depth in the outer sides of said staves near the first mentioned grooves and bands in said outer groo vessecured toand interlocked with said staves, two nails securing each hand to each stave initsoutergroove, the 10 outer faeesof the hands ihei ngsuhstantially flush with the outer faces of the staves and the meeting edges of the staves being longitudinally uninterrupted and adapted to be drawn ti ;htly together when the staves are assem bled on the heads and additional hoops sur- .ro1 1 nding the staves adjacent the heads.
