Abstract
Abstract An inclined material delivery means is provided and has passing therethrough a plurality of intermediary receptacle means for receiving predetermined amounts of material to subsequently be transferred to a container. The intermediary delivery means is agitated to provide a uniform and precise amount of material and contains on the bottom thereof door members which synchronize movement of the container therewith in the discharge area. Cutting means are provided to aid in proper filling of the intermediary receptacles as well as air supplies to appropriately direct the material being packaged.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
169 words
A machine for transferring predetermined amounts of material to a plurality of containers which comprises: a. a plurality of buckets each having an interior portion for receiving the material to be transferred and a downwardly opening hinged door means at the bottom of said bucket; b. means for delivering the material to be transferred to said plurality of buckets; c. means for conveying said plurality of buckets with respect to the machine in a path extending from said delivering means to a position adjacent the containers; d. means for moving the containers to a position adjacent said plurality of buckets; and e. means for releasing said hinged door means away from one of said buckets when the latter is adjacent one of the containers so as to enable the material to be discharged therefrom into the container, said door means being of a length sufficient to engage and thereby advance the container therebeneath so as to provide a means for synchronizing the movement of said buckets and the containers.
Claim 2
Dependent Claim
169 words
A machine for transferring predetermined amounts of material to a plurality of containers which comprises: a. a plurality of buckets each having an interior portion for receiving the material to be transferred and a downwardly opening hinged door means at the bottom of said bucket; b. means for delivering the material to be transferred to said plurality of buckets; c. means for conveying said plurality of buckets with respect to the machine in a path extending from said delivering means to a position adjacent the containers; d. means for moving the containers to a position adjacent said plurality of buckets; and e. means for releasing said hinged door means away from one of said buckets when the latter is adjacent one of the containers so as to enable the material to be discharged therefrom into the container, said door means being of a length sufficient to engage and thereby advance the container therebeneath so as to provide a means for synchronizing the movement of said buckets and the containers.
Claim 3
Dependent Claim
61 words
A machine in accordance with claim 1 wherein said hinged door means extends substantially vertically when in the fully open position and engages the inner surface of the leading wall of the container, and said buckets contain thereon an actuator means for engaging and holding the door in the fully open position while the latter is in engagement with said container.
Claim 4
Dependent Claim
26 words
A machine in accordance with claim 1 which further includes means for directing fluid at said buckets to assist in the removal of the material therefrom.
Claim 5
Dependent Claim
12 words
A machine in accordance with claim 3 wherein said fluid is air.
Claim 6
Dependent Claim
62 words
A machine in accordance with claim 1 wherein said releasing means includes means disposed beneath the path of conveying of said buckets for holding said hinged door means in the closed position when in engagement therewith, said holding means terminating at the location where said buckets are adjacent the containers in order to release said hinged door means away from said bucket.
Claim 7
Dependent Claim
73 words
A machine in accordance with claim 5 wherein said door means includes a pair of pivoted doors and further comprising a pair of overlapping members each attached to a different one of said doors for maintaining said doors closed with respect to one another and abutment means disposed adjacent the path of travel of said overlapping members for engaging and moving said overlapping members to assist the closing of said doors attached thereto.
Claim 8
Dependent Claim
133 words
A machine in accordance with claim 1 wherein said door means comprises a pair of pivoted doors, said machine further including a first means for closing one of said pair of doors including a door-engaging member, means for moving said first closing means adjacent to the path of the conveying means in synchronism with the travel of a bucket, a rail member inclined relative to the path of the conveying means for guiding said door-engaging member to close one door of said doors, second means being disposed below the path of travel of the buckets for engaging the other door of said doors to close the same, said second means including an inclined portion for engaging said other door and causing the closing thereof subsequent to the partial closing of said one door.
Claim 9
Dependent Claim
91 words
A machine in accordance with claim 1 wherein said means for delivering material includes a rotatable drum having the interior thereof adapted to contain the material to be delivered enclosing a portion of said path of said conveying means, and means for rotating said druM about the longitudinal axis thereof which extends in the direction of movement of said conveying means, said longitudinal axis being inclined so that the input end of said conveyor means to said drum is lower than the output end of said conveying means to said drum.
Claim 10
Dependent Claim
36 words
A machine in accordance with claim 8 wherein said rotatable drum contains a perforated surface thereabout and means spaced adjacent thereto for directing fluid thereat to prevent the accumulation of material within the interior portion thereof.
Claim 11
Independent Claim
136 words
A method of transferring a predetermined amount of material from a receiving station to a container at a discharging station comprising: a. delivering material to be transferred to a bucket having a downwardly opening door member hingedly connected to the forward edge of the bucket; b. conveying the bucket in a path extending between the receiving station and the discharging station; c. moving the containers to the discharging station; d. opening the bucket door member in a downward direction until the door member is in a vertical position parallel to the forward portion of the bucket; e. engaging the container with the vertical extending door member while at the discharging station so that their movement at the discharging station is synchronized; and f. discharging the material from the bucket into the container at the discharging station.
Claim 12
Independent Claim
136 words
A method of transferring a predetermined amount of material from a receiving station to a container at a discharging station comprising: a. delivering material to be transferred to a bucket having a downwardly opening door member hingedly connected to the forward edge of the bucket; b. conveying the bucket in a path extending between the receiving station and the discharging station; c. moving the containers to the discharging station; d. opening the bucket door member in a downward direction until the door member is in a vertical position parallel to the forward portion of the bucket; e. engaging the container with the vertical extending door member while at the discharging station so that their movement at the discharging station is synchronized; and f. discharging the material from the bucket into the container at the discharging station.
Claim 13
Dependent Claim
30 words
The method of claim 10 which further includes directing a flow of air at the bucket during said step of discharging material therefrom thereby assisting the removal of material therefrom.
