Abstract
A pair of frustoconical bearings for supporting a roller-type applicator and carried within an elongate cylindrical container. One of the bearings is affixed to the closed end of the container while the other is affixed to a cap detachably securable to the open end. Cleaning fluid is directed to the applicator from a plurality of orifices spaced along conduits extending longitudinally within the container. The axis of each orifice is at a compound angle to urge rotation of the applicator and to urge the applicator toward the closed end of the container.
Claims9
An apparatus for holding a roller-type applicator, which applicator includes:
- an outer generally cylindrical surface,
- a centrally located bore, and
- a pair of opposed open ends,
- and for receiving pressurized liquid from a source thereof and for utilizing said liquid to rotate and clean said applicator, said apparatus comprising:
- a. a container including
- i. a continuous side wall,
- ii. a closed end, and
- iii. an open end;
- b. a cap detachably securable with the open end of said container and having fluid drainage means therethrough, said cap having
- i. a generally centrally located bearing support element carrying the other of said bearings,
- ii. at least two spaced apart arms extending outwardly from said bearing support element and having spaces therebetween defining said fluid drainage means, and
- iii. attachment means for detachably securing said cap to said container, said attachment means including a plurality of openings extending through the side wall of said container proximate the open end thereof, said openings sized and spaced to receive a terminal portion of said legs therethrough, and stop means carried by end of said legs for abutting the side wall of said container and limiting the length of the terminal portion of said legs received through said openings;
- c. a pair of spaced apart axially aligned bearings for rotatably supporting said applicator, one of said bearings being carried by the closed end of said container, the other of said bearings being carried by said cap;
- and
- d. fluid transfer means carried by said housing for receiving said pressurized fluid and for directing said fluid toward said applicator.

Apparatus for holding a roller-type applicator, said applicator including
- an outer generally cylindrical surface,
- a centrally located bore, and
- a pair of opposed ends,
- and adapted to receive a pressurized solvent from a source thereof to rotate and clean said applicator, said apparatus comprising:
- a. a container including
- i. a side wall,
- ii. a closed end, and
- iii. an open end;
- b. a gap detachably securable with the open end of said container and having fluid drainage means therethrough;
- c. a pair of spaced apart axially aligned bearings for rotatably supporting said applicator, one of said bearings being carried by the closed end of said container, the other of said bearings being carried by said cap;
- and
- d. fluid transfer means including
- i. elongate delivery conduit means extending longitudinally within said container, and
- ii. a plurality of orifices spaced along said delivery conduit means for directing streams of solvent toward the outer surface of the applicator to cause the applicator to rotate and for directing the streams of solvent toward the closed end of the container to increase the turbulence of the solvent.

Apparatus for holding a roller-type applicator, said applicator including
- an outer generally cylindrical surface having a nap,
- a centrally located bore, and
- a pair of opposed ends,
- and adapted to receive a pressurized solvent from a source thereof to rotate and clean said applicator, said apparatus comprising:
- a. a container including
- i. a side wall,
- ii. a closed end, and
- iii. an open end;
- b. a cap detachably securable with the open end of said container and having fluid drainage means therethrough;
- c. a pair of spaced apart axially aligned bearings for rotatably supporting said applicator, one of said bearings being carried by the closed end of said container, the other of said bearings being carried by said cap;
- and
- d. fluid transfer means including
- i. elongate delivery conduit means extending longitudinally within said container, and
- ii. a plurality of orifices formed along said conduit means, each orifice being at a compound angle for tangentially directing a stream of solvent toward the outer surface of the applicator to apply a torque to the applicator to cause the applicator to rotate in a given direction and toward the closed end of the container to increase the turbulence of the flow of the solvent through the nap.
