Abstract

Abstract A housing accommodates a body of cleaning liquid. An apertured drum is rotatably mounted above the level of the liquid and provided with an inlet and outlet opening for metallic articles to be cleaned. An actuating arrangement is provided for displacing the drum with reference to the housing to and from a position in which at least a portion of the drum periphery is immersed in the body of cleaning liquid. A drive rotates the drum at least when the same is in the aforementioned position.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 212 words
An apparatus for cleaning metallic articles, compriSing in combination, a housing; a body of cleaning liquid accommodated in said housing; an apertured drum mounted above the level of said liquid in said housing for selective rotation in mutually opposite directions, said drum having a peripheral wall provided with an axially elongated opening for inlet and outlet of metallic articles to be cleaned, said drum further having an inner cross-sectional contour so configurated that articles in said drum are directed to and through said opening in response to rotation of said drum in one predetermined direction; actuating means for displacing said drum with reference to said housing to and from a working position in which at least a portion of the drum periphery is immersed in said body of cleaning liquid; drive means for rotating said drum at least when the same is in said position; and a chute having an end portion and being mounted for movement to a first operating position in which said end portion is located beneath said drum in response to displacement of the latter from said working position, and to a second operating position in which said end portion is laterally withdrawn from beneath said drum in response to displacement of the latter to said working position.
Claim 2
Independent Claim 212 words
An apparatus for cleaning metallic articles, compriSing in combination, a housing; a body of cleaning liquid accommodated in said housing; an apertured drum mounted above the level of said liquid in said housing for selective rotation in mutually opposite directions, said drum having a peripheral wall provided with an axially elongated opening for inlet and outlet of metallic articles to be cleaned, said drum further having an inner cross-sectional contour so configurated that articles in said drum are directed to and through said opening in response to rotation of said drum in one predetermined direction; actuating means for displacing said drum with reference to said housing to and from a working position in which at least a portion of the drum periphery is immersed in said body of cleaning liquid; drive means for rotating said drum at least when the same is in said position; and a chute having an end portion and being mounted for movement to a first operating position in which said end portion is located beneath said drum in response to displacement of the latter from said working position, and to a second operating position in which said end portion is laterally withdrawn from beneath said drum in response to displacement of the latter to said working position.
Claim 3
Dependent Claim 59 words
An apparatus as defined in claim 1, said drum being mounted for rotation about an at least substantially horizontal axis, and said actuating means comprising a pair of arms having first end portions secured to respective opposite axial ends of said drum and second end portions mounted for pivotal movement to and from said position about a pivot axis.
Claim 4
Dependent Claim 43 words
An apparatus as defined in claim 2, said actuating means comprising a shaft constituting said pivot axis and being rigid with said second end portions; and said actuating means further comprising displacing means for pivotably displacing said arms to and from said position.
Claim 5
Dependent Claim 13 words
An apparatus as defined in claim 3, said displacing means being mechanical means.
Claim 6
Dependent Claim 13 words
An apparatus as defined in claim 3, said displacing means being electrical means.
Claim 7
Dependent Claim 13 words
An apparatus as defined in claim 3, said displacing means being hydraulic means.
Claim 8
Dependent Claim 13 words
An apparatus as defined in claim 3, said displacing means being pneumatic means.
Claim 9
Dependent Claim 44 words
An apparatus as defined in claim 3, said displacing means comprising a cylinder, a fluid-operated piston displaceable in said cylinder, a piston rod projecting from said cylinder, a lever fixed with said shaft, and articulated connecting means connecting said piston rod and said lever.
Claim 10
Dependent Claim 46 words
An apparatus as defined in claim 1, and further comprising a baffle received in said drum at least substantially co-extensive with the axial elongation thereof, said baffle being secured to an edge bounding said opening and projecting inwardly towards the axis of rotation of said drum.
Claim 11
Dependent Claim 31 words
An apparatus as defined in claim 1; further comprising a feed hopper arranged above said drum and having an outlet aperture; and closure means for closing said outlet aperture when desired.
Claim 12
Dependent Claim 19 words
An apparatus as defined in claim 1; further comprising a control console for controlling the functions of said apparatus.
Claim 13
Dependent Claim 22 words
An apparatus as defined in claim 11; further comprising timer means associated with said control console for timed control of said functions.
Claim 14
Dependent Claim 34 words
An apparatus as defined in claim 11, said control console being a discrete entity; and further comprising electrical conductor means constituting the sole connection between said control console and the remainder of said apparatus.
