Abstract
Abstract A packing crate or lug of the type particularly adapted for the boxing of grapes and similar foodstuffs. The lug differs from a substantially conventional lug in that it specifically includes elongated upwardly projecting locking members affixed to the top cleats and receivable within corresponding recesses defined in the bottom cleats of superimposed lugs. The members and recesses are so orientated as to preclude a shifting of the lugs both longitudinally and transversely of each other.

Claim 1
Independent Claim
364 words
In a packing lug, a pair of laterally spaced rectangular end pieces, a pair of side slats having the opposite ends thereof secured to the side edges of said end pieces so as to define a rectangular enclosure, a lid overlying said enclosure, said lid comprising top slats extending transversely between and overlying the upper edges of said end pieces, a pair of top cleats, one top cleat paralleling and directly overlying the upper edge of each end piece with the top slats therebetween, a naillike id lid fasteners fixed within and extending upwardly from the upper edges of said end pieces, said top slats and top cleats, at the opposite ends of the lid, both including outwardly opening and inwardly extending slots therein for slidable reception of the naillike lid fasteners therein upon an outward movement of the opposite ends of the lid for securing the lid to the end pieces in overlying relation thereto, and a bottom, said bottom comprising bottom slats extending transversely between and underlying the lower edges of said end pieces, and a pair of bottom cleats, said bottom cleats paralleling directly underlying and being secured to the lower edges of the end pieces with the bottom slats therebetween, each top cleat being rectangular and including parallel inner and outer edges, opposed ends and parallel substantially planar upper and lower surfaces, each top cleat including an elongated upwardly extending locking member secured to the upper surface of the cleat along one edge thereof and in spaced relation to the second edge and the opposed ends thereof, each bottom cleat being rectangular and including parallel inner and outer edges, opposed ends and parallel substantially planar upper and lower surfaces, each bottom cleat including an elongated recess in alignment with and sLightly larger than the elongated locking member of the corresponding top cleat for the reception of a similar locking member of a subjacent lug upon a stacking of the lugs, the recess in each bottom cleat being along the edge of the bottom cleat corresponding to said one edge of the overlying top cleat and in spaced relation to the second edge and the opposed ends of the bottom cleat.

Claim 3
Dependent Claim
15 words
The construction of claim 1, wherein said locking members and said recesses are substantially rectangular.
