Abstract
Abstract A treating barrel comprising a pair of spaced end members, a perforate body member extending between said end members and defining there between an internal, substantially cylindrical shaped zone for receiving articles to be treated. The body member is formed to define an opening therethrough which extends longitudinally between the end members and which has a width which is less than about one-sixteenth of the circumference of the cylindrically shaped zone. At least one tumbling rib, which extends along the interior surface of the body member between the end members is disposed substantially dimetrically opposite to the opening, the tumbling rib projecting radially inwardly of the interior surface of the body member into the zone and being designed to impart a cascading action to the articles in the barrel during oscillatory motion thereof. Means are provided on the end member for supporting the barrel for oscillatory movement about an axis which extends substantially longitudinally of the zone. The overall apparatus assembly includes a work carrier for supporting the treating barrel at a treating receptiacle, drive means for oscillating the barrel when the work carrier is operatively positioned at the treating receptacle and coacting stop means which are oriented relative to the opening in the barrel to normally limit the rotary movement of the barrel in both directions beyond an angularity at which the articles are discharged through the opening of the barrel.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
191 words
An apparatus for treating articles in bulk comprising a framework and a treating barrel supported thereby, said treating barrel including a pair of spaced end members and a perforated body member extending between said end members and defining an internal cylindrically shaped treating zone, said body member formed with a longitudinally extending opening of a width less than about one-sixth the circumference of said zone and at least one tumbling rib disposed in the interior of said zone substantially opposite to said opening, means on said end members for supporting said barrEl on said framework for rotation about an axis extending substantially longitudinally and centrally of said zone, and coacting stop means on said barrel and said framework selectively positionable in an operative position for restricting angular rotation of said barrel and an inoperative position enabling unrestricted rotation of said barrel in either direction, said stop means oriented relative to said opening in said barrel to limit rotary movement thereof when disposed in said operative position in either direction between an angularity of at least about 180* up to an angularity below that at which articles are discharged from said opening.
Claim 2
Independent Claim
191 words
An apparatus for treating articles in bulk comprising a framework and a treating barrel supported thereby, said treating barrel including a pair of spaced end members and a perforated body member extending between said end members and defining an internal cylindrically shaped treating zone, said body member formed with a longitudinally extending opening of a width less than about one-sixth the circumference of said zone and at least one tumbling rib disposed in the interior of said zone substantially opposite to said opening, means on said end members for supporting said barrEl on said framework for rotation about an axis extending substantially longitudinally and centrally of said zone, and coacting stop means on said barrel and said framework selectively positionable in an operative position for restricting angular rotation of said barrel and an inoperative position enabling unrestricted rotation of said barrel in either direction, said stop means oriented relative to said opening in said barrel to limit rotary movement thereof when disposed in said operative position in either direction between an angularity of at least about 180* up to an angularity below that at which articles are discharged from said opening.
Claim 3
Dependent Claim
52 words
The apparatus as claimed in claim 1 wherein the coacting stop means include a pair of stop blocks fixedly mounted on one of the end members of said barrel and an engaging member movably mounted on the framework supporting said barrel and selectively positionable in said operative position and said inoperative position.
Claim 4
Dependent Claim
25 words
The apparatus as claimed in claim 1 wherein the treating zone of the barrel supported in said framework is of a substantially circular cross-sectional configuration.
Claim 5
Dependent Claim
47 words
The apparatus as claimed in claim 3 wherein the tumbling rib in said zone has substantially non-parallel sides which extend in a convergent direction into the zone and form an angle with the body member which is substantially within the range of about 10* to about 60*.
Claim 6
Dependent Claim
59 words
The apparatus as claimed in claim 4 wherein the sides of the tumbling rib in the barrel are at an angle within the range of about 20* to 40* with the body member and the width of the opening in the body member is within the range of about one-tenth to one-twentieth of the circumference of the treating zone.
Claim 7
Dependent Claim
31 words
The apparatus as claimed in claim 5 wherein the body member of the barrel is indented inwardly substantially opposite the elongated opening in the body member, to form the tumbling rib.
Claim 8
Dependent Claim
42 words
The apparatus as claimed in claim 6 wherein electrode members are disposed within the treating zone formed by the body member of the barrel so as to be in contact with the articles to be treated which are contained within the zone.
Claim 9
Independent Claim
269 words
An apparatus for treating articles in bulk comprising a treating receptacle and a work carrier adapted to be disposed at said treating receptacle during the treating operation, said work carrier comprising a framework and a hollow cylindrically shaped perforate treating barrel including a pair of spaced end members and a perforated body member extending between said end members and defining an internal cylindrically shaped treating zone, said barrel mounted on said framework for rotation about an axis extending substantially longitudinally and centrally of said treating zone, said treating barrel being formed with an elongated opening extending longitudinally of the end portions there of of a width less than about one-sixth the circumference of said zone through which articles to be treated are loaded into and unloaded from said barrel, at least one tumbling rib disposed in the interior of said zone substantially opposite to said opening, supporting means at said receptacle for supporting and retaining said work carrier in appropriate position relative thereto, drive means for oscillating said barrel when said work carrier is appropriately positioned at said receptacle, and coacting stop means on said barrel and said framework selectively positionable in an operative position for restricting angular rotation of said barrel and an inoperative position enabling unrestricted rotation of said barrel in either direction, said stop means oriented relative to said opening in the barrel to normally control the rotary movement of said barrel when disposed in said operative position so that its angular movement in either direction ranges from at least about 180* up to an angularity below that at which articles are discharged from said opening.
