Claim 1
Independent Claim
225 words
Storage and retrieving means comprising a storage rack having a storage bed on which stored items rest, the bed having at least one roller on which a stored item rests; a frame movable with respect to the rack; receiving means carried by the frame for receiving and supporting an item from the rack; an extractor slide mounted on the frame for movement from an extended position wherein it projects beyond the end of the bed to a retracted position wherein it is withdrawn from the rack and bed roller; first drive means for extending and retracting the slide; inner and outer rollers carried by the extractor slide and rotatable about axes fixed with respect to the slide; a drive roller and an idler roller carried by the frame and rotatable about axes fixed with respect to the frame; and endless belt trained around the drive roller, outer roller, inner roller, and idler roller; second drive means for moving the belt around the drive, outer, inner, and idler rollers; the belt being engageable with the bed roller when the slide is extended for revolving the bed roller such that the item resting thereon is shifted toward the receiving means; and third drive means for moving the frame upwardly and downwardly so that the belt can be brought into engagement with the withdrawn from the bed roller
Claim 2
Dependent Claim
225 words
Storage and retrieving means comprising a storage rack having a storage bed on which stored items rest, the bed having at least one roller on which a stored item rests; a frame movable with respect to the rack; receiving means carried by the frame for receiving and supporting an item from the rack; an extractor slide mounted on the frame for movement from an extended position wherein it projects beyond the end of the bed to a retracted position wherein it is withdrawn from the rack and bed roller; first drive means for extending and retracting the slide; inner and outer rollers carried by the extractor slide and rotatable about axes fixed with respect to the slide; a drive roller and an idler roller carried by the frame and rotatable about axes fixed with respect to the frame; and endless belt trained around the drive roller, outer roller, inner roller, and idler roller; second drive means for moving the belt around the drive, outer, inner, and idler rollers; the belt being engageable with the bed roller when the slide is extended for revolving the bed roller such that the item resting thereon is shifted toward the receiving means; and third drive means for moving the frame upwardly and downwardly so that the belt can be brought into engagement with the withdrawn from the bed roller
Claim 3
Dependent Claim
211 words
Storage and retrieving means comprising a storage rack having a storage bed on which stored items rest and including a plurality of rollers, the upwardly presented surfaces of which define a substantially planar surface which is inclined upwardly away from the end of the bed from which the items are discharged, the rollers being shiftable upwardly and downwardly between a loading position and a normal position; a frame movable with respect to the rack; receiving means carried by the frame for receiving and supporting an item discharged from the rack; a fixed stop located between the receiving means and the rollers, the slop being presented above the upper surfaces of the rollers when the rollers are in their normal position so as to prevent items from moving toward the receiving means, the stop being presented below the upper surfaces of the rollers when the rollers are in their loading position so that the stop does not obstruct the passage of items from the bed to the receiving means; and extractor means carried by the frame and including an endless belt which engages the rollers, lifts them upwardly to Their loading position, and rotates them such that the item is moved over the top of the stop and onto the receiving means.
Claim 4
Dependent Claim
211 words
Storage and retrieving means comprising a storage rack having a storage bed on which stored items rest and including a plurality of rollers, the upwardly presented surfaces of which define a substantially planar surface which is inclined upwardly away from the end of the bed from which the items are discharged, the rollers being shiftable upwardly and downwardly between a loading position and a normal position; a frame movable with respect to the rack; receiving means carried by the frame for receiving and supporting an item discharged from the rack; a fixed stop located between the receiving means and the rollers, the slop being presented above the upper surfaces of the rollers when the rollers are in their normal position so as to prevent items from moving toward the receiving means, the stop being presented below the upper surfaces of the rollers when the rollers are in their loading position so that the stop does not obstruct the passage of items from the bed to the receiving means; and extractor means carried by the frame and including an endless belt which engages the rollers, lifts them upwardly to Their loading position, and rotates them such that the item is moved over the top of the stop and onto the receiving means.
Claim 5
Dependent Claim
41 words
A retrieving unit according to claim 2 wherein the receiving means comprises a plurality of receiving rollers and means for rotating the receiving rollers such that the item when it moves onto them will be moved away from the storage rack.
Claim 6
Dependent Claim
86 words
A retrieving unit according to claim 3 wherein the extractor means is further characterized by an extractor slide on which at least a portion of the belt is carried, the extractor slide being shiftable from a retracted position wherein it is located outwardly from the rack to an extended position wherein it projects beneath the shiftable rollers of the bed, and wherein elevating means are provided for raising and lowering the frame, whereby the belt can be brought into engagement with and will raise rollers bed.
