Abstract

A hand-holdable trimmer for garden and lawn applications has an elongated housing defining an air passage extending from the trimmer'"'"'s rotating trimmer head to a collection container for cuttings mounted distally on the housing. An impeller wheel driven by the trimmer motor causes air to flow under positive pressure from the region surrounding the trimmer head through the housing air passage to eventually deliver the trimmer cuttings to the collection container. A dual, axially adjustable trimmer head assembly also is provided to more efficiently cut grass, weeds, etc. into small pieces capable of being easily transferred to the collection container.

Claims

1. A combined trimmer and vacuum apparatus for use in a garden, said apparatus comprising:

an elongate housing;

said housing having a first end and an opposed second end, said first end defining a first housing end opening, said housing having a passage extending between said first housing end opening and said housing opposed second end,

a drive motor mounted on said housing in communication with said passage,

an impeller mounted on said housing,

means coupling said drive motor to said impeller to cause rotation of said impeller,

a rotating trimmer head assembly mounted for rotation in said first end opening, and

a drive shaft between said drive motor and said trimmer head assembly wherein said rotation of said impeller causes air to flow through said passage from said first end opening simultaneously upon rotation of said trimmer head assembly;

wherein said housing opposed second end includes first, second and third openings,

wherein said housing has a container mounted thereon in communication with said second housing opposed end first and second openings, wherein said passage communicates with said container through said second housing opposed end first opening;

wherein said second housing opposed end further includes a hollow portion defining an interior compartment, said impeller is mounted for rotation in said interior compartment and said second housing opposed end second and third openings communicate respectively with said interior compartment, and

wherein said second housing opposed end second opening is disposed between said interior compartment and said container such that air flowing through said passage enters said container through said second housing end first opening, passes from said container into said interior compartment through said second housing end second opening and exits said interior compartment through said second housing opposed end third opening.

2. The apparatus of claim 1 wherein said drive shaft between said motor and said head assembly is also coupled to said impeller.

3. The apparatus of claim 1 wherein said impeller is connected to said motor and said drive shaft is connected to said impeller.

4. The apparatus of claim 1 wherein said container is removably mounted on said housing.
