1. A materials carrying apparatus, comprising:
- (a) a frame;
(b) a first carrier supported within said frame for carrying materials thereon, and located in an access position for access to and use of the materials by a user;
(c) a second carrier supported for vertically reciprocating movement within said frame on opposing first and second attached support hooks, and located in a storage position for carrying materials thereon, the storage position being vertically spaced apart from said access position;
(d) elevator means comprising first and second opposing, endless traveling chains operatively connected to said frame for vertically moving said second carrier from the storage position into the access position when the materials of said first carrier have been exhausted, and said first and second traveling chains including cooperating inwardly-projecting support pins for detachably engaging respective first and second hooks of said second carrier, whereby the support pins of said traveling chains automatically disengage from the hooks of said second carrier as said second carrier moves vertically from the storage position into the access position.

11. A materials carrying apparatus, comprising:
-
(a) a frame; (b) a supporting surface within said frame for carrying materials thereon, and located in an access position for access to and use of the materials by a user; (c) a carrier supported for vertically reciprocating movement within said frame on opposing first and second attached support hooks, and located in a storage position for carrying materials thereon, the storage position being vertically spaced apart from said access position; and (d) elevator means comprising first and second opposing, endless traveling chains operatively connected to said frame for vertically moving the carrier front the storage position to the access position when the materials carried by the supporting surface have been exhausted, and said first and second traveling chains including cooperating inwardly-projecting support pins for detachably engaging respective first and second hooks of said carrier, whereby the support pins of said traveling chains automatically disengage from the hooks of said carrier as said carrier moves vertically from the storage position into the access position.
