Claim 7

In apparatus for storing, gravity-feeding and selectively dispensing generally cylindrical products of a plurality of differing kinds including products of at least one kind to be accommodated in quantities greater than for products of a number of remaining kinds: cabinet means presenting an internal product storage space of limited available volume within which said products are to be stored and from which said products are to be selectively dispensed, said space having upper and lower zones; means presenting a delivery station below said space to which said products are to be selectively dispensed and from which dispensed products are to be made accessible to a user; means presenting a plurality of side-by-side staggered stack type product receiving chambers in the lower zone of said space, there being a chamber for each of said kinds of products respectively for receiving and storing a first quantity of the latter in a staggered stack arrangement, the lower extremity of said chambers being open, the upper extremity of the chambers for said one kind of products being provided with a product-clearing opening; means presenting a staggered stack type product supporting and releasing mechanism for each of said chambers respectively, said mechanisms each being disposed adjacent the open lower extremity of the corresponding chamber and adapted for normally supporting the lowermost product in the corresponding staggered stack and thereby the other products above said lowermost product in said stack and for releasing said lowermost article and dispensing the same to said delivery station when said mechanism is actuated; a pair of inclined shelf means disposed one above the other and each including at least one inclined shelf in the upper zone of said space for receiving and storing additional quantities of products of said one kind in a side-by-side rollable row arrangement upon each of said shelves; means including product guiding structure presenting a pair of side-by-side passageway means for guided movement of said additional quantities of products of said one kind by gravity from the lower extremity of the shelves for each of said pair of shelf means respectively to said product-clearing opening and into the upper portion of said chamber for said one kind of products to replenish the staggered stack of the latter therein as the same are dispensed, said product guiding structure laterally confining said additional quantities of products moving through said passageway means into a pair of separate vertical column arrangements which merge together into a staggered stack arrangement adjacent said product-clearing opening at the upper extremity of said chamber for said one kind of products; and means for selectively actuating any of said mechanisms.
