Abstract
Abstract A feed wheel for use in sorting apparatus for feeding beans or other similar articles to be sorted in single file into a viewing head in which the objects are optically examined to detect those of undesirable quality or characteristics. This feed wheel is provided with two disc members that are supported in spaced relation by a hub that may be readily disassembled. Peripheral portions of the disc members are provided with inwardly projecting flanges for gripping and supporting a plurality of small scoops extending around the circumference of the disc members. A plurality of locking devices are provided to the disc members for holding the disc members clamped against the scoops so that said scoops can be removed and replaced only when the locking members are disengaged. Several of the feed wheels may be mounted on a rotatable shaft and rotated at a selected speed through a supply of beans or other articles to be sorted so that the scoops each pick up one of such articles which are then projected in single file through the sorting apparatus viewing head.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
103 words
A feed wheel for use in apparatus for sorting small particles, such as beans, comprising the combination of a pair of disc members, a hub, one of said members being attached to said hub, means detachably supporting the other of said members on said hub, said members being positioned on said hub in parallel spaced relation, a plurality of particle-receiving scoops each having attaching means which when the scoop is positioned between peripheral portions of said disc members will engage said disc members and releasable locking means for clamping and locking said peripheral portions of said disc members to releasably hold said scoops.
Claim 2
Dependent Claim
103 words
A feed wheel for use in apparatus for sorting small particles, such as beans, comprising the combination of a pair of disc members, a hub, one of said members being attached to said hub, means detachably supporting the other of said members on said hub, said members being positioned on said hub in parallel spaced relation, a plurality of particle-receiving scoops each having attaching means which when the scoop is positioned between peripheral portions of said disc members will engage said disc members and releasable locking means for clamping and locking said peripheral portions of said disc members to releasably hold said scoops.
Claim 3
Dependent Claim
46 words
A feed wheel for use in apparatus for sorting small particles, such as beans, the combination as set forth in claim 1, further comprising resilient means positioned between said disc members urging said peripheral portions apart to release said scoops when said locking means is released.
Claim 4
Dependent Claim
61 words
A feed wheel for use in apparatus for sorting small particles, such as beans, the combination as set forth in claim 1, further characterized in that said locking means comprises a plurality of rotatable latching devices, means supporting said latching devices on one of said disc members and means engaging said latching devices supported on the other of said disc members.
Claim 5
Dependent Claim
46 words
A feed wheel for use in apparatus for sorting small particles, such as beans, the combination as set forth in claim 1, further characterized in that said disc members have opposing flanges and said attaching means of said scoops includes disc recesses for receiving said flanges.
Claim 6
Dependent Claim
111 words
A feed wheel for use in apparatus for sorting small particles, such a beans, comprising the combination of a pair of disc members, a hub, one of said members being attached to said hub, means detachably supporting the other of said members on said hub, said members being positioned on said hub in parallel spaced relationship, a plurality of particle receiving scoops, said disc members having means gripping and holding said scoops in a position to extend from peripheral portions of said disc members, releasable locking means attached to said disc members adjacent to said peripheral portions, said locking means holding said gripping means of said disc members against said scoops.
Claim 7
Dependent Claim
111 words
A feed wheel for use in apparatus for sorting small particles, such a beans, comprising the combination of a pair of disc members, a hub, one of said members being attached to said hub, means detachably supporting the other of said members on said hub, said members being positioned on said hub in parallel spaced relationship, a plurality of particle receiving scoops, said disc members having means gripping and holding said scoops in a position to extend from peripheral portions of said disc members, releasable locking means attached to said disc members adjacent to said peripheral portions, said locking means holding said gripping means of said disc members against said scoops.
Claim 8
Dependent Claim
37 words
A feed wheel for use in apparatus for sorting small particles, such as beans, the combination as set forth in claim 5, further characterized in that said gripping means comprises inwardly turned flanges gripping said scoops therebetween.
Claim 9
Dependent Claim
120 words
A feed wheel for use in apparatus for sorting small particles, such as beans, comprising the combination of a hub, a plurality of scoops each having a bowl with a recess therein shaped to receive substantially one small particle, means for mounting the scoops for rotation about the hub, a reservoir for holding a quantity of small particles so the scoops will pass therethrough and each will pick up one small particle in the recess, said scoops' bowl being tilted forward slightly from a radial line passing through the scoop bowl and the axis of the hub such that the beans will be ejected from the recess along a single file stream tangential to the circular path of the scoops.
Claim 10
Dependent Claim
120 words
A feed wheel for use in apparatus for sorting small particles, such as beans, comprising the combination of a hub, a plurality of scoops each having a bowl with a recess therein shaped to receive substantially one small particle, means for mounting the scoops for rotation about the hub, a reservoir for holding a quantity of small particles so the scoops will pass therethrough and each will pick up one small particle in the recess, said scoops' bowl being tilted forward slightly from a radial line passing through the scoop bowl and the axis of the hub such that the beans will be ejected from the recess along a single file stream tangential to the circular path of the scoops.
Claim 11
Dependent Claim
39 words
A feed wheel for use in apparatus for sorting small particles such as beans, comprising the combination recited in claim 7 and further characterized in that the forward tilt of the bowl is approximately 5° from the radial line.
Claim 12
Dependent Claim
48 words
A feed wheel for use in apparatus for sorting small particles such as beans, comprising the combination recited in claim 8 and further characterized in that the hub is rotated a speed sufficient to cause movement of the scoops at a velocity of approximately 254 feet per minute.
