WILLIAM H. DOBLE, QUINCY, MASSACHUSETTS, ASSIGNOR OF ONE-FOURTH TO 'l PNEUMATIC SCALE CORPORATION, LIMITED, OF QUINCY, MASSACHUSETTS, A COIR- PORATION OF MAINE.

To all/whom it may concern:

Be it known that l, WILLIAM H. DOBLE, citizen of the United States, residing at Quincy, county of Norfolk, State of Massachusetts, have invented a certain new and useful Improvement in Panels for Boxes, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to a box panel having an inner and outer wall spaced apart from each other, being specially intended for use in a box or shipping case of the folding variety in which the panel forming one side of the box is hinged to apanel forming another side of the box, and by the term side7 is meant any one of the four sides or the top or bottom of the box.

The invention is especially adapted for a metal box, although it will be obvious that other material may be employed, and also that a panel constructed in accordance with the invention may be employed in construetion of boxes which are not of the knockdown or folding variety.

The present invention is an improvement on the box panel shown in Patent No. 941,013, granted to Doble and Wheaton November' 23, 1909, in which the panel has a double wall comprised of two parallel plates spaced apart from each other and has an intermediate corrugated plate whose corrugations contact alternatelywith said first two plates.

The present invention comprises an inner and an outer plate spaced apart from each other forming respectively the inner and outer faces of the panel, and a plurality of corrugated plates side'by side between the said inner and outer plates, one corrugated plate having corrugations which alternately engage with the inner face plate of the panel and with another corrugated plate, said other corrugated plate bein in engagement alternately with the other ace plate of the panel and with said rst corrugated plate, and said two corrugated plates having portions which engage withceach other alternately with the portions lwhich engage with the face plate. By corrugated plate is meant broadly a plate of zig zag form.

The invention will be fully understood from the following description when taken in connection with the accompanying draw- Specication of Letters Patent.

ings and the novel features thereof will be pointed out and clearly defined in the claims at the close of the specification. In the drawings,-Figure 1 is a plan view partly brokenvaway of a panel embodying thev invention.

.1F ig. 2 is a section on line 2-2 of Fig. l. Fig. 3 is a section on line 3 3 of Fig. 1. Fig. 4 is a modification of the corrugated 'plate which is made in sections instead of continuous.

Fig. 5 is a sectional view at right angles to Fig. 4.

Fig 6 shows an additional plate interposed between two corrugated plates.

Referring now to the drawin s,-1 represents one of the face plates ofg the panel and 2 represents the other face plate, said two face plates being for convenience termed respectively the outer and the inner face plates, meaning by the term outer face plate the one which will be the outside plate of the panel when assembled with other anels to form a box and the inner plate being the one which will form the inside face of the panel of a finished box. These two plates 1 and 2 are spaced some distance apart fromeach otherand interposed between said plates 1 and 2 are two corrugated plates 3, 4, each of which has corrutions 3a which contact with the inner face of the plate land depressed portions 3b in another plane which contact with the depressed portions 4D of the plate 4, said plate 4 having elevated portions 4a in'one plane which engage with the inner face of the plate 2. In saying that the corrugations extend transversely of the plates, it is meant that they extend substantially from one edge to the opposite edge of the corrugated plate whether longitudinally onwidthwise. Thus the 'elevated and depressed portions 3a and 3b of the corrugated plate 3 respectively engage alternately with the face plate 1 and the corrugated plate 4, and the alternating elevated and depressed portions of the corrugated plate 4 respectively engage alternately with the face plate 2 and corrugated plate 3., The corrugated Iplates brace and stiften each' other and also the inner and outer face plates of the entire panel.

Preferably these corrugations form a seclose the open space at the edge.

ries'of troughs extending the entire length or width, as the case may be, of the corrugated plate, with fiat surfaces which contact with the face plates and with the companion corrugated plate. Preferably also the corrugations of the 'plate 3 extend at right angles to the corrugations of the plate 4 so that, as shown in Fig. 2 the bottom of the trough or the corrugation of the plate 3 will not only rest upon the depressedportions 4b of the corrugated plate 4 but will also bridge across the space between said depressed portions 4b of the plate 4 and also the depressed portions 4b of the said plate 4 will contact with the depressed portions 3b of the plate and will bridge across the space between said depressed portions 3b as shown in Fig. 3.

The said corrugated plates 3, 4 and thev face plates land 2 are preferably all secured together at their respective contact points to prevent their becoming displaced and the preferred method of thus uniting them is by welding.

Preferably'the se corrugated plates do'not extend quite to the edges of the inner and outer plates, thus leaving at they edges a place for the insertion of channel plates to For instance, on one edge, as in Fig. 2, a U-shaped channel plate 5 is inserted which extends across the entire end orside of the panel and in another edge is inserted a channel plate 6 which also closes that edge and is formed with a series of eye portions 7 adapted to receive a hinge pin to connect the said panel with another panel having a series of eyes which it in between the eyes 7 In the modification shown in Fig. 4 instead of having two continuous corrugated plates each bracing the other they are made in sections. For instance, in place of the integral corrugated plate 4 shown in Fig. 1 there are employed a' series of plates 8 shapedsomething like the letter Z alternating with reversely turned Z-shaped plates each having a-portion 8a which bears against one of the sections 9 of a corresponding corrugated plate and another portion 8b which bears against the face plate 2, and an inclined connecting portion 8c. Each one of these sections 8 and 9 extends crosswise of the panel in one direction, the sections 8 and 9 being at right angles to each other in the same Way that the corrugated plates 3 and 4 are placed at right angles to each other so v that each one of the sections 9 will bear against a series of sections 8 and each one of thesections 8 will bear against a series of sections 9.

`It is not essential that the corrugated plates 3 and 4 should be in actual contact with each other. There may be, if desired, an additional plate interposed between said plates 3 and 4, as shown in Fig. 6, in which the plate 10 is interposed so that the corrugated plates 3 and 4 instead of coming directly in contact withv each other come in contact with the said interposed plate, and in the claims in which it is stated that the said corrugated plates engage each other it is intended to use thatexpression broadly to cover either direct physical contact with each other or through the medium of an interposed plate. What l claim is:

l. A box panel consistin of two metallic face plates spaced .apart from ,each other, two metalliccorrugated plates inserted between said two face plates, one of said corrugated plates having' portions which engage with one of said face plates and the other of said corrugated plates having porthe engaging portions of said plates being welded together at the points of contact.

2. A box panel consisting of two metallic face plates spaced apart f roin each other,
