Abstract
Abstract In a dispensing machine, a magazine is provided in which a multiplicity of packets to be dispensed are maintained in a magazine supported by clips which support the packets on a helical screw. The packets are dispensed individually by energizing a motor to turn the screw, during which the endmost packet drops into a receiving tray. The drop of the packet is detected by a photosensitive detector, and the screw driving motor is deenergized. The magazine contains a channel for maintaining the packets in single-file relationship as they are advanced toward the end of the screw in response to rotation of the screw. The tray into which the packets are dropped is slidable between an inner position, in which it is disposed below the dispensing magazine, and an outer position in which the contents of the tray are accessible to an operator. The tray is forced toward an outer position, and a motorized drive is provided for moving the tray backwardly and forwardly when the tray is in a rearward position.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
177 words
In a magazine assembly for a dispensng machine, the combination comprising a screw having a helical thread, a plurality of separate articles hung by hangers from said screw, supporting means for supporting said screw at one end for rotation, with the opposite end of said screw located above an article receiving area, said thread having a first portion with a continuous thread in which adjacent convolutions of said thread are spaced apart by a first distance, and a second portion, coaxial said first portion and interposed between said first portion and said opposite end, said second portion having a thread which meets smoothly with the thread of said first portion and in which adjacent convolutions of the thread are spaced apart by a distance greater than said first distance, said thread having the same handedness in both said first and second portions, some of the convolutions of said second portion being flattened on one side to enable a separation of said hangers so that a maximum of one hanger resides between adjacent convolutions of said opposite end.
Claim 2
Dependent Claim
177 words
In a magazine assembly for a dispensng machine, the combination comprising a screw having a helical thread, a plurality of separate articles hung by hangers from said screw, supporting means for supporting said screw at one end for rotation, with the opposite end of said screw located above an article receiving area, said thread having a first portion with a continuous thread in which adjacent convolutions of said thread are spaced apart by a first distance, and a second portion, coaxial said first portion and interposed between said first portion and said opposite end, said second portion having a thread which meets smoothly with the thread of said first portion and in which adjacent convolutions of the thread are spaced apart by a distance greater than said first distance, said thread having the same handedness in both said first and second portions, some of the convolutions of said second portion being flattened on one side to enable a separation of said hangers so that a maximum of one hanger resides between adjacent convolutions of said opposite end.
Claim 3
Dependent Claim
65 words
Apparatus according to claim 1, wherein said thread has a third portion, between said second portion and said opposite end, the shank of said screw being enlarged toward said opposite end within said third portion, with the radius of the shank at said opposite end being approximately equal to the radius of curvature at a surface of said hanger which is supported by said screw.
Claim 4
Dependent Claim
82 words
Apparatus according to claim 2 wherein each of said hangers has a curved portion extending around said screw and adapted to be juxtaposed with the shank of said screw at opposite sides thereof near said opposite end, said thread at said opposite end being only slightly larger than said shank, whereby said hangers can be loaded onto said opposite end by rectilinear movement in the axial direction, said hangers being resiliently deformed temporarily as they pass over said third portion during loading.
Claim 5
Dependent Claim
11 words
Apparatus according to claim 1, wherein said hangers comprise paper clips.
Claim 6
Dependent Claim
23 words
Apparatus according to claim 1, wherein said supporting means includes pivot means, whereby said screw may be pivoted upwardly about a horizontal axis.
Claim 7
Dependent Claim
31 words
Apparatus according to claim 1, including a motor for rotating said screw, and including photosensitive means disposed below said opposite end for detecting the dropping of an article from said screw.
Claim 8
Dependent Claim
24 words
Apparatus according to claim 6, including means responsive to said photosensitive means for deactiviating said motor in response to detection of a dropped article.
Claim 9
Dependent Claim
42 words
Apparatus according to claim 1, including a drawer movable between an outer position and an inner position, said inner position being located at said article receiving area, whereby articles dropped from said screw are received by said drawer at its inner position.
Claim 10
Dependent Claim
54 words
Apparatus according to claim 8, including a can interposed between said screw and said drawer, said can having a vertical tubular body and a hinged flap normally closing the top of said can, and means for moving said flap to open the top of said can when said drawer is in its inner position.
Claim 11
Dependent Claim
22 words
Apparatus according to claim 9, including fan means mounted in fixed relation to said can for agitating the air beneath said screw.
Claim 12
Dependent Claim
30 words
Apparatus according to claim 1 wherein the threads of said first portion are spaced such that a maximum of five hangers can be supported within four convolutions of said helix.
Claim 13
Dependent Claim
27 words
Apparatus according to claim 1 wherein the convolutions of said second portion are spaced by a distance slightly less than the thickness of two of said hangers.
