Abstract
Abstract An apparatus for coating confectionary centers, medical tablets or similar articles, comprising a rotary drum, the internal space of which is divided into a plurality of chambers for receiving and holding separate batches of articles. The chambers are separated from one another by substantially diametrical partition walls that are moved axially through the drum so that the chambers travel in the same direction and preferably with increasing capacity or volume.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
89 words
Article coating apparatus, comprising a drum mounted for rotation about its substantially horizontal axis and defining an article tumbling space, said drum having an inlet and a discharge opening for the articles, a plurality of movably supported partitions dividing said tumbling space into an axial series of individual chambers to hold separate batches of articles, means for moving said partitions parallel to said axis, said separate batches of articles being moved with said partitions, and means for supplying coating material and ventilating air in adjustable quantities to said chambers.
Claim 2
Dependent Claim
89 words
Article coating apparatus, comprising a drum mounted for rotation about its substantially horizontal axis and defining an article tumbling space, said drum having an inlet and a discharge opening for the articles, a plurality of movably supported partitions dividing said tumbling space into an axial series of individual chambers to hold separate batches of articles, means for moving said partitions parallel to said axis, said separate batches of articles being moved with said partitions, and means for supplying coating material and ventilating air in adjustable quantities to said chambers.
Claim 3
Dependent Claim
30 words
Article coating apparatus as claimed in claim 1, comprising means for moving said partitions from one end of said drum to the other end thereof at a stepwise increasing velocity.
Claim 4
Dependent Claim
124 words
Article coating apparatus, comprising a drum mounted for rotation about its substantially horizontal axis and defining an article tumbling space, said drum having an inlet and a discharge opening for the articles, a stationary frame structure extending through said drum from one end thereof to the other end, a plurality of partitions slidably supported by said stationary frame structure and dividing said tumbling space into an axial series of individual chambers to hold separate batches of articles, a plurality of endless chain drives disposed in successive and pairwise overlapping relationship, said chain drives having catching means for moving said partitions along said frame structure over individual longitudinal sections thereof, and means for supplying coating material and ventilating air in adjustable quantities to said chambers.
Claim 5
Dependent Claim
124 words
Article coating apparatus, comprising a drum mounted for rotation about its substantially horizontal axis and defining an article tumbling space, said drum having an inlet and a discharge opening for the articles, a stationary frame structure extending through said drum from one end thereof to the other end, a plurality of partitions slidably supported by said stationary frame structure and dividing said tumbling space into an axial series of individual chambers to hold separate batches of articles, a plurality of endless chain drives disposed in successive and pairwise overlapping relationship, said chain drives having catching means for moving said partitions along said frame structure over individual longitudinal sections thereof, and means for supplying coating material and ventilating air in adjustable quantities to said chambers.
Claim 6
Dependent Claim
64 words
Article coating apparatus as claimed in claim 3, wherein said endless chain drives in their ares of overlap have a common shaft carrying at least one set of co-rotating sprockets belonging to a preceding and a subsequent chain drive, respectively, the diameter of the sprocket belonging to the subsequent chain drive being larger than that of the sprocket belonging to the preceding chain drive.
Claim 7
Dependent Claim
76 words
Article coating apparatus as claimed in claim 3, wherein said partitions have the shape of circular plates with a diameter that is substantially as large as that of said drum, and with a sector-shaped cut defined by a substantially horizontal edge pointing towards the descending side of said rotary drum and an upwardly inclined edge pointing towards the ascending side of the drum, said cut leaving a space within the drum for accommodating said frame structure.
