KNOCKDOWN BOX.

Specification of Letters Patent.

Patented Oct. 3, 1905.

10 1110/ w/mm, it nuty concern:

Be it known that I, JOHN N. SIsLnY, a citizen of the United States, residing at Oonnellsville, in the county of Fayette and State of Pennsylvania, have invented a new and useful Knockdown Box, of which the following is a specification.

The invention relates to improvements in knockdown boxes.

The object of the present invention is to improve the construction of knockdown boxes and to provide a simple, inexpensive, and eflicient one of great strength and durability capable of affording a firm structure when set up and adapted to be compactly folded when not in use.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective view of a knockdown box constructed in accordance with this invention. Fig. 2 is alongitudinal sectional view of the same. Fig. 3 is a transverse sectional view. Fig. 4 is an enlarged detail perspective view illustrating the arrangement of the angle-strips at one of the corners of the box. Fig. 5 is a horizontal sectional view of one corner of the box. Fig. 6 is a detail perspective view of a portion of the cover or top, illustrating the construction of the locking devices for securing the sections of the cover in alinement when the box is closed.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 1 designate the sides of the knockdown box, provided at their end edges with anglestrips 2, which overlap and engage the ends 3 of the box. The ends 3 are provided at their upper and lower edges with angle-strips 4 and 5, which overlap and engage the top or cover 6 and the bottom 7 of the box. The top and bottom are provided at their side edges with angle-strips 8 and 9, which overlap and engage the sides 1 of the box, as

clearly illustrated in Fig. 3 of the drawings. The angle-strip 2, which may be constructed of any suitable metal, is composed of

flanges

10 and 11, arranged at right angles to each other, the flange 10 being secured to the side by the means hereinafter described and the flange 11 extending inward from the sides and overlapping the side edge of the adjacent end 3 of the box. The flange 10 is provided at intervals with integral tongues 12, formed by r partially severing the metal of the flange 10 and bent inwardly at right angles to the inner face of the said flange 10. The tongues pierce the side 1 and are clenched at the inner face thereof, as shown at 13 in Fig. 2 of the drawings. The other flange 11 is imperforate, and the angle-strip 2 is strengthened by corrugations 14, consisting of oppositely-tapered protuberances formed by stamping or otherwise pressing the metal outward from the inner faces of the flanges. These protuberances are preferably semicircular in cross-section and taper from the angle of the strips toward the side edges thereof. Any number of the protuberances, which extend transversely of the strip, may be employed, as will be readily understood. The tongues, which are preferably arranged in pairs, are spaced apart, and the protuberances are located at the spaces between the pairs of tongues. The ends 15 of the flanges are cut at an angle to provide a neat fit at the corners of the box, the other flanges being correspondingly cut at the corners. As all of the angle-strips employed in the construction of the box are alike, a detail description of the strip 2 is suflicient to fully explain their construction.

The bottom 7 of the box is placed upon the inwardly-extending bottom flanges of the ends 3 of the box and is interposed between the said ends 3, thereby spacing the latter and preventing the same from movinginwardly. The imperforate side flanges of the angle-strip of the bottom 7 extend upwardly, and the sides 1 are fltted against the inner faces of the side flanges and against the side edges of the ends 3, which space the sides of the box, and prevent the same from moving inwardly toward each other. The side flanges of the bottom 7 prevent any outward movement of the side 1 of the box. The projecting flanges of the movement of the same.

interposed between the upper portions of the ends of the box, prevents any inward movement of the same, and its end edges are en gaged by the upper projecting flanges of the ends of the box. The projecting portions of the angle-strips at the sides of the top of the box extend downward and engage the outer faces of the sides 1 and prevent any outward movement thereof. By this construction the parts or members of the box are firmly bound together and a structure of great strength is provided.

The bottom, sides, and ends are assembled before the top or cover is placed in position, and in order to enable the same to be effected the top orcover is composed of two sections, being divided transversely, as clearly shown at 16 in Figs. 1 and .2 of the drawings, and the angle-strips of the top are provided at the depending flanges with overlapped perforated portions or ears, which are connected by pivots or pintlcs 17, whereby the two sections of the top are hinged together. One of the sections of each angle-strip is provided with a projecting finger 18 and tapering outwardly, as clearly shown in 1 and 6 of the drawings, and presenting an inclined upper edge when the sections of the cover are in aline ment. The projecting finger 18 is adapted to engage a shoulder or stop 19 of the other section of the angle-strip, and it is retained in such engagement by its resiliency, the metal being sufliciently resilient to form a spring-catch. The stop or shoulder consists of a protuberance formed by pressing the metal outwardly from its inner face, and the catch or finger is adapted to be readily sprung into and outof engagement with the same. The lower face of the protuberance which forms the stop or shoulder is straight, and the upper portion of the protuberance presents a substantially inclined face for enabling the catch or finger to be readily engaged with the shoulder. in placing the top or cover on the box the sections are arranged at an angle to each other, as indicated in dotted lines in Fig. 2 of the drawings, and a slight downward pressure on the sections will carry them into a horizontal position, and the catches will automatically engage the stops and lock the cover or top in its closed position.

It will be seen that the knockdown box is exceedingly simple and inexpensive in construction, that the angle-strips not only connect the parts, but reinforce the same, and that the tongues which bind the angle-strips to the parts of the box obviate the necessity of employing nails or similar fastening devices.

Although the box shown in the accompanying drawings is oblong or of a greater length than width and although the vertical walls of the box are described as sides and ends, yet it will be readily understood that the box may be made of any desired dimensions and that the side and end walls may be of equal area. The top, bottom, sides, and ends of the box will in practice be constructed of a plurality of boards, as will be readily understood.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
