Abstract
Abstract A product and material storage system having blocks of cells arranged in tiers around a plurality of shafts in which a lift moves to carry a load to any selected tier or level, and a means is provided in said lift for moving the loads laterally from the shaft into and from selected cells along the shaft. The load preferably enters and leaves the shaft at the top, and a floor covers the top of the structure so that a vehicle for operating the lift and carrying the load to and from the shaft can be maneuvered to any desired location and over any particular shaft. Covers close the upper ends of the shafts and provide a smooth floor, the covers being removable, preferably by the load carrying vehicle, when a load is to be introduced into or removed from a particular shaft. The cells may be in groups of various numbers including three, four and six to obtain a dense storage arrangement without the necessity of moving one load in order to reach or deposit another load.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
119 words
A product and material storage system comprising a storage structure having a plurality of spaced vertical shafts with blocks of storage cells disposed on at least three sides of the shaft and arranged in vertical tiers of two or more separate cells for receiving and storing individual loads, said cells being directly and separately accessible from the respective adjacent shaft, a floor above said storage structure, a top cover for each of said shafts on substantially the same plane as said floor, lift means including a carriage and movable above said floor from one shaft to another with a load, said carriage including means for moving a load suspended thereby laterally into and from a cell along a shaft.
Claim 2
Dependent Claim
119 words
A product and material storage system comprising a storage structure having a plurality of spaced vertical shafts with blocks of storage cells disposed on at least three sides of the shaft and arranged in vertical tiers of two or more separate cells for receiving and storing individual loads, said cells being directly and separately accessible from the respective adjacent shaft, a floor above said storage structure, a top cover for each of said shafts on substantially the same plane as said floor, lift means including a carriage and movable above said floor from one shaft to another with a load, said carriage including means for moving a load suspended thereby laterally into and from a cell along a shaft.
Claim 3
Dependent Claim
38 words
A product and material storage system as defined in claim 1 in which each of said shafts is rectangular in cross sectional shape and four cells are disposed around said shaft at each tier accessible from said shaft.
Claim 4
Dependent Claim
37 words
A product and material storage system as defined in claim 1 in which each of said shafts is rectangular in cross sectional shape and three cells are disposed on three sides of said shaft and accessible therefrom.
Claim 5
Dependent Claim
49 words
A product and material storage system as defined in claim 1 in which said shafts are arranged in said storage structure in parallel rows with tiers of cells disposed between said rows, the size of the cells between said rows being shallower than the cells disposed in said rows.
Claim 6
Dependent Claim
65 words
A product and material storage system as defined in claim 1 in which said vehicle includes a means for removing the cover from any one of said shafts, a hoist means having a cage for descending into a selected shaft, and means on said cage for supporting a load and for moving the load laterally into and from a pre-selected cell along the selected shaft.
Claim 7
Dependent Claim
60 words
A product and material storage system as defined in claim 1 in which said shafts are defined by a plurality of vertical posts and include tracks for guiding and stabilizing said carriage as it moves vertically in said shafts and while it is depositing a load in and removing a load from any one of the cells along the shaft.
Claim 8
Dependent Claim
112 words
In a product and material storage system having a plurality of spaced vertical shafts with cells disposed on at least three sides of the shaft and arranged in tiers of two or more cells, and a floor above said structure with covers for said shafts: a load handling vehicle for maneuvering a load over said floor and into a position above any selected shaft, including a means for removing the cover for said shaft, a hoist means having a carriage for descending into a selected shaft, and a means on said carriage for supporting a load and for moving a load laterally into and from any pre-selected cell along the selected shaft.
Claim 9
Dependent Claim
112 words
In a product and material storage system having a plurality of spaced vertical shafts with cells disposed on at least three sides of the shaft and arranged in tiers of two or more cells, and a floor above said structure with covers for said shafts: a load handling vehicle for maneuvering a load over said floor and into a position above any selected shaft, including a means for removing the cover for said shaft, a hoist means having a carriage for descending into a selected shaft, and a means on said carriage for supporting a load and for moving a load laterally into and from any pre-selected cell along the selected shaft.
