Abstract
Abstract A dispensing device for small parts arranged in a compact shape from when the parts can be withdrawn from a single point including a plurality of vertically stacked trays slidably disposed upon banks of spaced flanges which are rotatable about a central axis of the device and reciprocable in a plane parallel to the central axis. The uppermost and lowermost trays in the stack are free to rotate with the flanges and the balance of the trays are restrained from rotation so as to be disengaged from one bank of flanges and received between the planes of another bank of flanges.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
108 words
A dispensing device comprising: at least two banks of flanges, flanges of one bank being arranged to reciprocate into coplanar relationships with flanges of the other bank; a plurality of stacked trays having compartments formed therein, slidably disposed upon and supported by said flanges; means to index simultaneously the top tray supported on the one bank of flanges and the bottom tray supported on the other bank of flanges; and means to restrain indexing of intermediate trays disposed below said top tray on said one bank and above said bottom tray on said other bank whereby said intermediate trays will index from one bank to the other bank.
Claim 2
Dependent Claim
108 words
A dispensing device comprising: at least two banks of flanges, flanges of one bank being arranged to reciprocate into coplanar relationships with flanges of the other bank; a plurality of stacked trays having compartments formed therein, slidably disposed upon and supported by said flanges; means to index simultaneously the top tray supported on the one bank of flanges and the bottom tray supported on the other bank of flanges; and means to restrain indexing of intermediate trays disposed below said top tray on said one bank and above said bottom tray on said other bank whereby said intermediate trays will index from one bank to the other bank.
Claim 3
Dependent Claim
17 words
The device according to claim 1 wherein said banks are rotatably disposed about a central support means.
Claim 4
Dependent Claim
41 words
The device according to claim 2 further including means to reciprocate said banks of flanges whereby when the trays are fully on one bank or the other, said top tray can be lowered while simultaneously said bottom tray can be raised.
Claim 5
Dependent Claim
39 words
The device according to claim 1 wherein the means to restrain indexing of trays includes a plurality of removable retaining means arranged so as to be disposed in each of the spaces between adjacent flanges to abut said trays.
Claim 6
Dependent Claim
53 words
The device according to claim 2 wherein in the means to index the top tray includes a key disposed normal to the axis of rotation and extending outwardly from said central support means to engage the sides of the top tray and index the compartments of said top tray to a dispensing station.
Claim 7
Dependent Claim
21 words
The device according to claim 1 further including means for retaining said trays upon said flanges during operation of the device.
Claim 8
Dependent Claim
28 words
The device according to claim 6 wherein the retaining means includes a housing having a generally cylindrical internal shape arranged to slidably engage the perimeter of said trays.
Claim 9
Dependent Claim
44 words
The device according to claim 1 further including a top disposed over said stacked trays and means defining an aperature in a fixed location in said top, whereby an operator can reach through said aperature into the tray and remove an article contained therein.
Claim 10
Dependent Claim
145 words
A dispensing device comprising: at least two tray slides centrally disposed within said device and arranged together in a cylindrical form; at least two banks of flanges, flanges of one bank being arranged to reciprocate into coplanar relationships with flanges of the second bank, one of said banks being disposed on one of the tray slides and the other being disposed on the other tray slide; means to index said tray slides about a central axis; a plurality of trays slidably supported on each of said banks of flanges; means to index simultaneously the top tray supported by one of the banks of flanges and the bottom tray supported on the other bank of flanges and means to restrain indexing of trays disposed intermediate said top and bottom trays; means to reciprocate said tray slides in opposite directions in planes parallel to the central axis.
Claim 11
Dependent Claim
145 words
A dispensing device comprising: at least two tray slides centrally disposed within said device and arranged together in a cylindrical form; at least two banks of flanges, flanges of one bank being arranged to reciprocate into coplanar relationships with flanges of the second bank, one of said banks being disposed on one of the tray slides and the other being disposed on the other tray slide; means to index said tray slides about a central axis; a plurality of trays slidably supported on each of said banks of flanges; means to index simultaneously the top tray supported by one of the banks of flanges and the bottom tray supported on the other bank of flanges and means to restrain indexing of trays disposed intermediate said top and bottom trays; means to reciprocate said tray slides in opposite directions in planes parallel to the central axis.
