Abstract
Abstract The combination of an open-framed cart and a plurality of containers or lugs, as they are called in this art, is disclosed which fit together in a number of convenient carrying arrangements. The containers have transverse spaced grooves in their bottom surfaces which fit upon and coincide with pairs of longitudinal and transverse frame members of the cart to hold the containers thereon during produce handling procedures. The cart has two tiers in the frame such that each tier can hold one container longitudinally or two containers transversely. The containers also nest in stacked relationship within each other and the longitudinal distance between the bottom grooves of the containers is the same as the transverse distance between their top longitudinal rolled flange edges so that one container will rest on the other in a stable relationship.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
91 words
A lug cart comprising: a frame member; wheels carrying said frame member for transport; said frame member including a bottom and a top tier spaced one above the other; said tiers each including parallel spaced side members and a pair of parallel spaced cross members; said cross members being below the plane of said side members; said side members being longer than said cross members and spaced from each other substantially the same distance transverse said frame as said cross members are spaced from each other along the longitudinal axis thereof.
Claim 2
Dependent Claim
91 words
A lug cart comprising: a frame member; wheels carrying said frame member for transport; said frame member including a bottom and a top tier spaced one above the other; said tiers each including parallel spaced side members and a pair of parallel spaced cross members; said cross members being below the plane of said side members; said side members being longer than said cross members and spaced from each other substantially the same distance transverse said frame as said cross members are spaced from each other along the longitudinal axis thereof.
Claim 3
Dependent Claim
147 words
A lug cart in accordance with claim 1 includinG a lug for use therewith; said lug comprising an open-topped container having spaced side and end walls connected by a bottom wall; the space between said side members of said cart being greater than the width of said bottom wall along one dimension; said bottom wall including protuberances on the underside extending parallel with said one dimension and spaced so as to engage over corresponding sides of said side members of said frame in a transverse position and so as to engage over corresponding sides of said cross members in a longitudinal position below the plane of said side members whereby at least one lug can be carried upon each of said tiers upon said cross members in a longitudinal disposition and at least two lugs can be carried upon each of said tiers in a transverse disposition.
Claim 4
Dependent Claim
36 words
A lug cart in accordance with claim 2 in which said protuberances are defined by grooves in the bottom wall of said lug members engageable on a side of said side and cross-members of said tiers.
Claim 5
Dependent Claim
88 words
A lug cart in accordance with claim 2 including: a pair of said lugs; each of said lugs being substantially identical molded plastic containers having a peripheral outwardly extending flange along the top edge of said side and end walls; and the contour of said flange and the width between opposite side walls conforming to the contour of said protuberances and their longitudinal spacing whereby one lug can be placed upon the other lug with the bottom wall of the former locked upon the flanges of the latter.
Claim 6
Dependent Claim
229 words
A mobile lug cart and lug combination comprising: a frame member; said frame member having a bottom and a top tier spaced one above the other; said tiers each including parallel spaced side members and a pair of parallel spaced cross-members intermediate the ends thereof and below the plane of said side members; said side members being longer than said cross members and spaced from each other substantially the same distance transverse said frame as said cross-members are spaced from each other along the longitudinal axis thereof; at least four identical lug members each comprising an open-topped container having spaced side and end walls connected by a bottom wall; the space between said side members being greater than the width of said bottom walls of said lug members; said bottom walls of each of said lug members each including protuberances on the underside spaced so as to engage over corresponding sides of said side members of said frame in a transverse position and so as to engage over corresponding sides of said cross-members in a longitudinal position below the plane of said side members; the space between said tiers being greater than the height of said lug members whereby each tier will carry one of said lug members in a longitudinal position on said cross-members and two of said lug members in a transverse position on said side members.
Claim 7
Dependent Claim
229 words
A mobile lug cart and lug combination comprising: a frame member; said frame member having a bottom and a top tier spaced one above the other; said tiers each including parallel spaced side members and a pair of parallel spaced cross-members intermediate the ends thereof and below the plane of said side members; said side members being longer than said cross members and spaced from each other substantially the same distance transverse said frame as said cross-members are spaced from each other along the longitudinal axis thereof; at least four identical lug members each comprising an open-topped container having spaced side and end walls connected by a bottom wall; the space between said side members being greater than the width of said bottom walls of said lug members; said bottom walls of each of said lug members each including protuberances on the underside spaced so as to engage over corresponding sides of said side members of said frame in a transverse position and so as to engage over corresponding sides of said cross-members in a longitudinal position below the plane of said side members; the space between said tiers being greater than the height of said lug members whereby each tier will carry one of said lug members in a longitudinal position on said cross-members and two of said lug members in a transverse position on said side members.
Claim 8
Dependent Claim
37 words
A mobile lug cart in accordance with claim 5 in which: said protuberances are defined by grooves in the bottom wall of said lug members engageable on a side of said side and cross-members of said tiers.
Claim 9
Dependent Claim
85 words
A mobile lug cart in accordance with claim 5 in which: each of said lugs being substantially identical molded plastic containers having a peripheral outwardly extending flange along the top edge of said side and end walls; and the contour of said flange and the width between opposite side walls conforming to the contour of said protuberances and their longitudinal spacing whereby one lug can be placed upon the other lug with the bottom wall of the former locked upon the flanges of the latter.
Claim 10
Dependent Claim
39 words
A mobile lug cart in accordance with claim 7 in which said protuberances are defined by spaced parallel grooves having a contour which conforms with the contour of the top portion of said side frame members and said cross-members.
Claim 11
Dependent Claim
51 words
A mobile lug cart in accordance with claim 5 having a handle member at one end with spaced legs attached to eAch of the pairs of side members of said top and bottom tiers; and a pair of spaced upright support members connected between the other end of said side members.
Claim 12
Dependent Claim
27 words
A mobile lug cart in accordance with claim 9 in which a cross member is provided between said spaced legs above the plane of said side members.
