Thisinvention relates to veneerbox construe tionslparticularly of the wire-bound, type that can'be stored and shipped in the form of prefabricated flat mats embodyingthe wall sections ready to beset to box form. by the user.- Theimainobject of. this invention is to an improved fastening for the? end wall members of veneerbox or wire-bound box constructions, whereby the end wall memberswill be fastened automatically and permanently :lo'y merely pushing, them into place against the cleatsof the side wall members; I v 1 1 Q A specific embodiment 'ofzthis invention is shown inxthe accompanying drawing inawhich: Figure l is aperspe'ctive view-ofja wire-bound box mat constructed according to this'invention and showing the same in a form inwhichit may be conveniently stored and delivered to theuser.

Fig. 2 is a"fragmentaryiperspective end view of thecomplete box: I n g Fig. 3 is a detail inpers'pectiveof one of the side wall cleats showing the manner incwhich it is provide attached tothe side wall; panel. r eend wall panels [6 have attached at each end oneor more fastening clips I! in the formof specially shaped staples. See 9. Thesestaples areformed of wire bent to rectangular U-form at its bosom portion l8 withparallellegs I!) that bend at right-angles to the plane .of the legs H! to form 1 fastening prongs 20 that are driven throughand clenched on the cleated margins of end panel as shownin Fig. 1.

Thelegs. [9 are spaced to correspond with the spacingbetween the grooves l5.in the cleats It andtthe squared bosom of the staple" enables it to snugly embrace the lug 2| which is formed on the cleat between the grooves l5. This lug 2|. is beveled at 22 tofacilitate the entrance of the clip when forced between the cleat l4 and the side wall H,q as illustrated in Figures 4 to 6 inclusive. ,Uponinaking theprongs 20 of clip staples ll, are driven through I the reinforcing cleats 23 of the end panels and grooved to accommodate thefastener for the'end wall. v Figs. 4, Sand 6 are similar fragmentary-sectional details showing successive positions" of the endwall. as:it is-pushed. into place-to latch the "fastener.

. Fig.7; is a. fragmentary end view illustrating themanner in which the side wallpanel and its reinforcing wire-binding yield during the instant' that the fastener traverses the. crest of the holding lug as; it. isslipped intoplace, and corresponding to the positionof the parts as shown in section in Fig. 5. I

Fig. '8 is a fragmentary detail showing the V fastener in its final position with respect to the v sidewall cleat and, corresponding to a section taken on the line 8-- -8 of Fig. 6.

Fig. 9 is a perspective vieW-of'the that forms the attached clip..

In the form shown in the drawing, the box consists of a series of panels of wooden veneer reinforced by cleats extending across the ends thereof. The cleats are positioned to be located on the inside surface of the side wall panels and.

these panels are further reinforced by binding of the box.

In Figure 1 the panel In forms the bottom of the box. The side panels II and I2 and the top I panel l3 are assembled in mat form in the relation shown.

The cleats M on the side members llt and l2 are grooved as shown in Fig. 3 to provide transin that face thereof that is wire staple clenched in such position that the body of the clip extendsbeyond the ends .ofthe panels i6 lying parallel with and substantially-flush with the inner faces of their reinforcing cleats and the s end panels are laid upon the side panels ll and I2, one being adjacent to the cleat-l4 at one end of one respective side panel and the other being adjacent the cleat I 4 at the other end of the othersidepanel. The panels [6 are then thrust edgewise toward the cleats ,I4 until the clips spring into engagement with the respective lugs 2|. Thus all the parts of the box are assembled .into asingle mat structure which can be handled without special attention to avoid loss of loose parts. 7 v 'When the boxis to be set up for use by the user,rthe sides" I l' and 12 :are turned to stand at right-angles to the bottom It. The free clips H are bent at right-angles over and across the respective ends of their end panels and then swung into position, as shown in Fig. 4, where a light hammer tap on the side panel over the legs l9 of the staple causes the staple to pass over the beveled corner 22, forcing the panel H to spring outwardly until the staple has passed into the position where it is shown in Fig. 6; whereupon the panel and its reinforcingwire 24 together with the resiliency of the staple causes the latter to move into the place where it snugly embraces the lug 2| and lies substantially flush withthe outer surface of the cleat l4.

It is to be observed that in attaching the staples to the end panels IS, the prongs are the m t as. illustrated in Fig. 1,

driven at a predetermined location so as to properly proportion the extending part of the body portion for the function that it is to serve, namely, that of a snap-in tongue shaped to enter between the side wall and its cleat. The bosom portion of the staple acts as a shoulder which engages the lug formed on the cleat and the tongue thus has self-locking latching engagement with the cleat.

Although but one specific embodiment of this invention is herein shown and described, it will he understood that numerous details of the construction shown may be altered or omitted Without departing from the spirit of the invention as defined by the following claims.

I claim:

1. A knock-down box comprising a side wall, a cleat within and secured to said wall, a transverse panel adapted to abut said wall and cleat, and a fastener secured to said panel and having a snap-in tongue shaped to enter between said sidewall and cleat, said cleat having a groove adjacent said wall to receive 'saiditongue and having a shoulder in the plane of 'said .groove, and said tonguehaving a shoulder positioned i ""eon for self-locking latching engagement '1 said cleat shoulder when said panel is pushed into abutting contact with saidLc'leat.

2. A box comprisinga side .wall, a cleat within and secured to said wall, an end wall-adapted .to abut said side wall and cleat, a stapleesh'aped clip having its legs secured to said end wall and having its medial portion positioned to stand at right-angles to said end wall for entrance between said side wall and cleat when said panel is pushed into abutting contact with said cleat,
