Abstract

Abstract A device is provided for dispensing sensitivity disks from cartridge rolls to a receptacle provided with wells for receiving the disks. The device comprises a housing having surfaces defining a base for receiving the receptacle. A first plate is fixed within the housing with openings offset from the receptacle wells when the receptacle is in a first position and aligned with the receptacle wells when the receptacle is in a second position. The first plate further includes wiper means affixed to the plate extending into the openings. The device further includes a second plate disposed for movement within the housing interposed between the first plate and the base. The second plate has openings in alignment with the receptacle wells when the receptacle is in the first position. Means affixed to the second plate engage with a portion of the receptacle so that when the receptacle is shifted to the second position the second plate moves with the receptacle. The device further includes a third plate affixed to the second plate for movement therewith. The third plate includes tubular openings therein in alignment with the first plate openings for supporting a cartridge roll.

Total Claims: 11
Claim 1
Independent Claim 223 words
A device for dispensing a sensitivity disk from a cartridge roll to a receptacle provided with a predetermined area for receiving the disk, said device comprising: a housing; surfaces on said housing defining a base for receiving said receptacle; a first plate disposed within said housing parallel to and spaced apart from said base, an opening in said plate, said opening being offset from said receptacle area when said receptacle is positioned on said base in a first position and aligned with said area when said receptacle is positioned on said base in a second position and wiper means affixed to said plate extending into said opening; a second plate disposed for movement within said housing interposed between said first plate and said base, an opening in said second plate in alignment with said receptacle area when a receptacle is positioned on said base in said first position; means affixed to said second plate for engagement with a portion of said receptacle when said receptacle is positioned on said base in said first position whereby when said receptacle is shifted to said second position, said second plate moves with said receptacle; and, a third plate affixed to said second plate for movement therewith, said third plate including a tubular opening therein in alignment with said first plate opening for supporting a cartridge roll.
Claim 2
Independent Claim 223 words
A device for dispensing a sensitivity disk from a cartridge roll to a receptacle provided with a predetermined area for receiving the disk, said device comprising: a housing; surfaces on said housing defining a base for receiving said receptacle; a first plate disposed within said housing parallel to and spaced apart from said base, an opening in said plate, said opening being offset from said receptacle area when said receptacle is positioned on said base in a first position and aligned with said area when said receptacle is positioned on said base in a second position and wiper means affixed to said plate extending into said opening; a second plate disposed for movement within said housing interposed between said first plate and said base, an opening in said second plate in alignment with said receptacle area when a receptacle is positioned on said base in said first position; means affixed to said second plate for engagement with a portion of said receptacle when said receptacle is positioned on said base in said first position whereby when said receptacle is shifted to said second position, said second plate moves with said receptacle; and, a third plate affixed to said second plate for movement therewith, said third plate including a tubular opening therein in alignment with said first plate opening for supporting a cartridge roll.
Claim 3
Dependent Claim 49 words
The device in accordance with claim 1 further comprising limiting means affixed to said housing for engagement with said second plate for limiting the movement of said second plate between a first position corresponding to said receptacle first position and a second position corresponding to said receptAcle first position.
Claim 4
Dependent Claim 30 words
The device in accordance with claim 1 further comprising spring means disposed within said housing bearing on said second plate biased to urge said second plate to said first position.
Claim 5
Dependent Claim 21 words
The device in accordance with claim 1 further comprising lock means for locking a cartridge in said third plate tubular opening.
Claim 6
Dependent Claim 41 words
The device in accordance with claim 1 wherein each of said first, second and third plates contain a plurality of openings therein aligned to receive and dispense a plurality of disks onto a plurality of predetermined areas of an associated receptacle.
Claim 7
Dependent Claim 78 words
The device in accordance with claim 4 wherein said cartridge comprises: an elongated cylindrical member having an open bottom end, a strap extending across said open bottom end, and a pair of flanges spaced above said bottom end extending transversely to said cartridge axis; and said locking means includes a slot disposed in said second plate for receiving said cartridge strap, said slot being aligned with said first plate opening when said receptacle is in said first position.
Claim 8
Dependent Claim 28 words
The device in accordance with claim 1 further comprising camming surface means directed toward said base affixed to said plate extending into said opening opposite said wiper means.
Claim 9
Dependent Claim 95 words
