Abstract
Abstract An ice piece dispenser for automatically dispensing pieces of ice from a collecting bin associated with an automatic ice maker. The dispenser includes a delivery member for transferring the ice pieces from the collecting bin to a delivery position. A metering device is provided at the transfer position between the collecting bin and delivery member for providing a metered delivery of the ice pieces to the delivery member which may have a relatively large delivery capacity so as to permit use of the apparatus in dispensing any one of a plurality of different size and shape ice pieces. The metering device may be any one of a plurality of different metering devices correlated with the size and configuration of the ice pieces intended to be dispensed in the apparatus. The device may define an anti-jamming element at the transfer position for reducing the size of aggregated ice pieces and cause a delivery of independent ice pieces to the delivery member for sequential delivery therethrough to the delivery position. The device may include connecting arms interlocked with the delivery member whereby concurrent rotation of the device and delivery member may be effected. The device may be disposed flush with one end of the delivery member at the transfer position.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
109 words
In an ice piece dispensing apparatus having means for providing a plurality of ice pieces to a transfer position, and a delivery member having a through passage for conducting ice pieces away from said transfer position to a delivery position, the improvement comprising metering means at said transfer position for providing a metered, sequentially independent delivery of said ice pieces one at a time to said passage at a rate substantially less than the maximum delivery capacity of said passage, said metering means being defined by a disc element having a plurality of outwardly extending projections restricting free movement of the ice from the transfer position into said passage.
Claim 2
Dependent Claim
109 words
In an ice piece dispensing apparatus having means for providing a plurality of ice pieces to a transfer position, and a delivery member having a through passage for conducting ice pieces away from said transfer position to a delivery position, the improvement comprising metering means at said transfer position for providing a metered, sequentially independent delivery of said ice pieces one at a time to said passage at a rate substantially less than the maximum delivery capacity of said passage, said metering means being defined by a disc element having a plurality of outwardly extending projections restricting free movement of the ice from the transfer position into said passage.
Claim 3
Dependent Claim
25 words
The ice piece dispensing apparatus of claim 1 wherein said passage has a maximum delivery capacity permitting delivery of ice pieces therethrough in side-by-side relationship.
Claim 4
Dependent Claim
29 words
The ice piece dispensing apparatus of claim 1 wherein said disc element has a diameter substantially less than the transverse dimension of the delivery member at said transfer position.
Claim 5
Dependent Claim
17 words
The ice piece dispensing apparatus of claim 1 wherein said metering means comprises a rotated disc element.
Claim 6
Dependent Claim
16 words
The ice piece dispensing apparatus of claim 1 wherein said disc element has an undulate periphery.
Claim 7
Dependent Claim
63 words
The ice piece dispensing apparatus of claim 1 wherein said disc element has a diameter substantially less than the transverse dimension of the delivery member at said transfer position and at least one connecting means extending from the disc element to said delivery member, and said metering means is rotated about a drive axis to revolve said delivery member concurrently about said axis.
Claim 8
Dependent Claim
32 words
The ice piece dispensing apparatus of claim 1 wherein said delivery member comprises a tubular drum having an end at said transfer position, and said metering means is flush with said end.
Claim 9
Dependent Claim
146 words
In an ice piece dispensing apparatus having means for providing a plurality of ice pieces to a transfer position, which ice pieces may at times become aggregated, and a delivery member having a through passage for conducting ice pieces away from said transfer position to a delivery position, said passage being sufficiently large in cross section to accommodate said ice pieces in side-by-side relationship, the improvement comprising rotated anti-jamming means at said transfer position for agitating and reducing the size of aggregated ice pieces to cause a delivery of independent ice pieces one at a time into said passage for sequential delivery therethrough to said delivery position, said anti-jamming means being defined by a disc element having an undulate peripheral portion arranged to roll said ice pieces at said transfer position and restrict free movement of the ice pieces from the transfer position into said passage.
Claim 10
Dependent Claim
146 words
In an ice piece dispensing apparatus having means for providing a plurality of ice pieces to a transfer position, which ice pieces may at times become aggregated, and a delivery member having a through passage for conducting ice pieces away from said transfer position to a delivery position, said passage being sufficiently large in cross section to accommodate said ice pieces in side-by-side relationship, the improvement comprising rotated anti-jamming means at said transfer position for agitating and reducing the size of aggregated ice pieces to cause a delivery of independent ice pieces one at a time into said passage for sequential delivery therethrough to said delivery position, said anti-jamming means being defined by a disc element having an undulate peripheral portion arranged to roll said ice pieces at said transfer position and restrict free movement of the ice pieces from the transfer position into said passage.
Claim 11
Dependent Claim
21 words
The ice piece dispensing apparatus of claim 8 wherein said anti-jamming means peripheral portion defines a plurality of outwardly extending projections.
Claim 12
Dependent Claim
42 words
The ice piece dispensing apparatus of claim 8 wherein said anti-jamming means comprises any one of a plurality of different size elements, and means for selectively rotatively mounting any selected one of said elements transversely to said passage at said transfer position.
Claim 13
Dependent Claim
32 words
The ice piece dispensing apparatus of claim 8 wherein said delivery member comprises a tubular drum having an end at said transfer position, and said anti-jamming means is flush with said end.
Claim 14
Dependent Claim
37 words
The ice piece dispensing apparatus of claim 8 wherein said anti-jamming means further defines means for metering delivery of ice pieces to said passage at a rate substantially less than the maximum delivery capacity of said passage.
Claim 15
Dependent Claim
48 words
The ice piece dispensing apparatus of claim 8 wherein said disc element carries a pair of opposed, outwardly extending arms engaging the delivery member, and means are provided for rotating said disc element about the axis thereof and thereby causing said arms to concurrently rotate said delivery member.
Claim 16
Dependent Claim
48 words
The ice piece dispensing apparatus of claim 8 wherein said disc element carries a pair of opposed, outwardly extending diametrically offset arms engaging the delivery member, and means for rotating said disc element about the axis thereof and thereby causing said arms to concurrently rotate said delivery member.
Claim 17
Dependent Claim
13 words
The ice piece dispensing apparatus of claim 8 wherein said passage is helical.
