Abstract
Abstract A pellet dispensing device having a rotor member with a pellet passage for transporting a pellet to a discharge opening. The rotor member has an escapement groove at the bottom for pieces of the pellet to be accommodated so that they do not jam the full sized pellets in the pellet passage. In a preferred embodiment, there is an additional groove at the top of the rotor member and in communication with the pellet passage which allows full sized pellets to be ejected therefrom by a dam member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
179 words
A dispensing device for pellets comprising: a container means having a wall portion with an opening; a pellet discharge means; a rotor assembly operatively connected with said container wall opening and said pellet discharge means, said rotor assembly including a rotor member having at least one pellet carrying passage, said pellet carrying passage having a pellet entry portion and a pellet exit portion, said pellet carrying passage being in communication with said container wall opening and in a selected position being in communication with said pellet discharge means; dam means positioned above said rotor member to eject excess pellets out of said pellet carrying passage; drive means operatively associated with said rotor member to rotate said rotor member; wherein said pellet discharge means is positioned adjacent the bottom of said rotor assembly when mounted in connection with the container means; and wherein said rotor member includes escapement means in communication with said exit portion of said pellet carrying passage to permit smaller than average size pellets to enter when said rotor member is moved toward said pellet discharge means.
Claim 2
Dependent Claim
179 words
A dispensing device for pellets comprising: a container means having a wall portion with an opening; a pellet discharge means; a rotor assembly operatively connected with said container wall opening and said pellet discharge means, said rotor assembly including a rotor member having at least one pellet carrying passage, said pellet carrying passage having a pellet entry portion and a pellet exit portion, said pellet carrying passage being in communication with said container wall opening and in a selected position being in communication with said pellet discharge means; dam means positioned above said rotor member to eject excess pellets out of said pellet carrying passage; drive means operatively associated with said rotor member to rotate said rotor member; wherein said pellet discharge means is positioned adjacent the bottom of said rotor assembly when mounted in connection with the container means; and wherein said rotor member includes escapement means in communication with said exit portion of said pellet carrying passage to permit smaller than average size pellets to enter when said rotor member is moved toward said pellet discharge means.
Claim 3
Dependent Claim
28 words
The dispensing device of claim 1 wherein said escapement means is defined by a groove member having a depth smaller than the average largest dimension of said pellets.
Claim 4
Dependent Claim
32 words
The dispensing device of claim 2 wherein said groove member is defined by a sloping wall portion which tapers in a narrowing manner in the direction of said pellet carrying discharge passage.
Claim 5
Dependent Claim
18 words
The dispensing device of claim 2 wherein said escapement means is defined by two opposing accurate groove members.
Claim 6
Dependent Claim
31 words
The dispensing device of claim 1 further including a sloping wall which tapers in a narrowing manner away from said pellet carrying passages as they are rotated in said rotor assembly.
Claim 7
Dependent Claim
17 words
The dispensing device of claim 1 wherein said dam means is positioned over said pellet discharge means.
Claim 8
Dependent Claim
171 words
A rotor assembly for a pellet dispensing device comprising: a rotor housing adapted to receive a pellet container wall, said rotor housing also including a pellet discharge means; a rotor member disposed in said rotor housing having at least one pellet carrying passage, said pellet carrying passage having a pellet entry portion and a pellet exit portion, said pellet carrying passage being in communication with said container wall opening and in a selected position being in communication with said pellet discharge means, said rotor member adopted to be driven by a drive means; dam means positioned above said rotor member to eject excess pellets out of said pellet carrying passage; wherein said pellet discharge means is positioned adjacent the bottom of said rotor assembly when mounted in connection with said container means; and wherein said rotor member includes escapement means in communication with said exit portion of said pellet carrying passage to permit smaller than average size pellets to enter when said rotor member is moved toward said pellet discharge means.
Claim 9
Dependent Claim
171 words
A rotor assembly for a pellet dispensing device comprising: a rotor housing adapted to receive a pellet container wall, said rotor housing also including a pellet discharge means; a rotor member disposed in said rotor housing having at least one pellet carrying passage, said pellet carrying passage having a pellet entry portion and a pellet exit portion, said pellet carrying passage being in communication with said container wall opening and in a selected position being in communication with said pellet discharge means, said rotor member adopted to be driven by a drive means; dam means positioned above said rotor member to eject excess pellets out of said pellet carrying passage; wherein said pellet discharge means is positioned adjacent the bottom of said rotor assembly when mounted in connection with said container means; and wherein said rotor member includes escapement means in communication with said exit portion of said pellet carrying passage to permit smaller than average size pellets to enter when said rotor member is moved toward said pellet discharge means.
Claim 10
Dependent Claim
198 words
A three component dispensing device for pellets comprising: a rotor housing adapted to receive a pellet container wall, said rotor housing also including a pellet discharge means; a rotor member disposed in said rotor housing having at least one pellet carry passage, said pellet carrying passage having a pellet entry portion and a pellet exit portion, said pellet carrying passage being in communication with said container wall opening and in a selected position being in communication with said pellet discharge means, said rotor member having groove portions in lateral communication with said pellet entry and exit portions and at the same side of said pellet carrying passage, said rotor member also adopted to be driven by drive means; and a dam member positioned above said rotor member to eject excess pellets out of said pellet carrying passage; wherein said pellet discharge means is positioned adjacent the bottom of said rotor assembly when mounted in connection with the container means; and wherein said groove portions in communication with said exit portion of said pellet carrying passage provide escapement means to permit smaller than average size pellets to enter when said rotor member is moved toward said pellet discharge means.
