Abstract

A vacuum cleaner nozzle movable back and forth over a rug of the long pile or shag-type in which the nozzle is provided with a pile rake with means for mounting the rake adjacent the entrance to the nozzle but exteriorly of the air passage from the entrance for movement of the teeth toward and away from the entrance on the normal back and forth movement of the nozzle, the means for mounting comprising confining means for rather loosely confining the rake ends on the nozzle so that the back-and-forth movement of the nozzle will cause the rake teeth to dig into the pile thereby resulting in aiding removal of dirt from the rug and lifting of the pile from a matted condition to a normal and attractive loose condition.

Claims

1. A vacuum cleaner nozzle movable back-and-forth over a rug having a long pile during cleaning of said rug, comprising:

a nozzle body having a suction air passage therein with an entrance adapted to contact said pile during cleaning;

a pile rake having opposite ends and spaced teeth projecting below said entrance and the rug contacting portions of said teeth are curved in a direction away from said nozzle entrance to function as skids during movement of said nozzle in a direction opposite to said direction of curvature of the teeth; and

means for mounting said rake adjacent to said entrance and to one side thereof for movement of said teeth toward and away from said entrance on said back-and-forth movement of said nozzle, said means for mounting comprising confining means for loosely confining said rake adjacent to the entrance of said nozzle for lateral movement of the rake relative to the confining means.

2. A vacuum cleaner nozzle movable back-and-forth over a rug having a long pile during cleaning of said rug, comprising:

a nozzle body having a suction air passage therein with an entrance adapted to contact said pile during cleaning;

a pile rake having opposite ends and spaced teeth projecting below said entrance and the rug contacting portions of said teeth are curved in a direction away from said nozzle entrance to function as skids during movement of said nozzle in a direction opposite to said direction of curvature of the teeth;

means for mounting said rake adjacent to said entrance and to one side thereof for movement of said teeth toward and away from said entrance on said back-and-forth movement of said nozzle, said means for mounting comprising confining means for loosely confining said rake adjacent to the entrance of said nozzle for lateral movement of the rake relative to the confining means; and

an air passage wand portion on said nozzle at an acute angle to said nozzle entrance in which said rake is on the same side of said entrance as said wand portion.

3. A vacuum cleaner nozzle movable back-and-forth over a rug having a long pile during cleaning of said rug, comprising:

a nozzle body having a suction air passage therein with an entrance adapted to contact said pile during cleaning;

a pile rake having opposite ends and spaced teeth projecting below said entrance and the rug contacting portions of said teeth are curved in a direction away from said nozzle entrance to function as skids during movement of said nozzle in a direction opposite to said direction of curvature of the teeth;

means for mounting said rake adjacent to said entrance and to one side thereof for movement of said teeth toward and away from said entrance to said back-and-forth movement of said nozzle, said means for mounting comprising confining means for loosely confining said rake adjacent to the entrance of said nozzle for lateral movement of the rake relative to the confining means and a removable closure bracket at each end of said nozzle defining the bottoms of chambers in which said rake ends are rather loosely confined; and

an air passage wand portion on said nozzle at an acute angle to said nozzle entrance in which said rake is on the same side of said entrance as said wand portion.

4. A vacuum cleaner nozzle movable back-and-forth over a rug having a pile during cleaning of said rug, comprising:

a nozzle body having a suction air passage therein with an entrance adapted to contact said pile during cleaning;

a pile rake having opposite ends and spaced teeth projecting below said entrance; and

means for mounting said rake adjacent to said entrance but exteriorly of said passage for movement of said teeth toward and away from said entrance on said back-and-forth movement of said nozzle, the rug contacting portions of said teeth are curved in a direction away from said nozzle entrance to function as skids during movement of said nozzle in a direction opposite to said direction of curvature of the teeth.

5. The nozzle of claim 4 wherein said nozzle is provided with an air passage wand portion at an acute angle to said nozzle entrance and said rake is on the same side of said entrance as is said wand portion.

6. A vacuum cleaner nozzle movable back-and-forth over a rug having a long pile during cleaning of said rug, comprising:

a nozzle body having a suction air passage therein with an entrance adapted to contact said pile during cleaning;

a pile rake having opposite ends and spaced teeth;

means for mounting said rake adjacent to said entrance for movement of said teeth toward and away from said entrance on said back-and-forth movement of said nozzle, said means for mounting comprising confining means for loosely confining said rake adjacent to the entrance of said nozzle; and

a rigidly mounted brush between said entrance and said rake.

7. A vacuum cleaner nozzle movable back-and-forth over a rug having a pile during cleaning of said rug, comprising:

a nozzle body having a suction air passage therein with an entrance adapted to contact said pile during cleaning;

a pile rake having opposite ends and spaced teeth projecting below said entrance;

means for mounting said rake adjacent to said entrance but exteriorly of said passage for movement of said teeth toward and away from said entrance on said back-and-forth movement of said nozzle, the rug contacting portions of said teeth are curved in a direction away from said nozzle entrance to function as skids during movement of said nozzle in a direction opposite to said direction of curvature of the teeth;

an air passage wand portion on said nozzle at an acute angle to said nozzle entrance, said rake and said wand portion being on the same side of said entrance; and

a rigidly mounted brush between said entrance and said rake.
