Abstract

A nozzle for use with a lawn and garden blower provides a comparatively wide pattern of high velocity air. The nozzle includes a substantially hollow, tubular housing tapering from the upstream end to the downstream end. At the downstream end is a plurality of bores arranged side-by-side to divide the air stream into a plurality of high velocity air streams substantially parallel to one another as the plurality of air streams exit the nozzle from a plurality of apertures proximate the downstream end.

Claims

1. A portable powered leaf blower comprising:

a motor;

a fan driven by the motor for generating a single stream of high velocity air;

a housing in which the motor and fan are mounted, the housing including means for manually carrying the blower in an elevated position; and

an elongated, hollow tube having a first end coupled to the housing for receiving the single stream of high velocity air from the fan and a second end including a nozzle for discharging the high velocity air, the nozzle having a terminating end portion wherein there is defined a plurality of bores lying side-by-side in a common plane for dividing the single stream of air into a plurality of substantially parallel, side-by-side high-velocity air streams, each of the bores having a diameter smaller than that of the conduit.

2. The blower in accordance with claim 1 wherein each of the plurality of bores has an axis and whereby the plurality of bores are oriented such that the axes of the bores are substantially parallel to one another and lie substantially within a common plane.

3. The blower in accordance with claim 1 wherein each of the bores has a substantially circular cross-section.

4. The blower in accordance with claim 1 wherein the downstream end of the nozzle further includes a blade disposed on a bottomside of the nozzle, for scraping objects along the ground.

5. The blower in accordance with claim 1 wherein the nozzle curves such that the bores lie in a common plane substantially parallel to the ground for directing the discharge of the plurality of air streams in a direction substantially parallel to the ground when a user manually carries the blower in a normal, elevated operating position by the means for carrying.

6. A portable powered leaf blower comprising:

a motor;

a fan driven by the motor for generating a stream of high velocity air;

a housing in which the motor and fan are mounted, the housing including means for manually carrying the blower in an elevated position; and

an elongated conduit means having a first end coupled to the fan for receiving the stream of high velocity air from the fan, a second end including a nozzle having defined in a terminating end thereof a plurality of bores for dividing the stream of air into a plurality of substantially parallel, side-by-side air streams;

wherein the nozzle curves such that the bores are aligned for directing the discharge of the plurality of air streams in a direction substantially parallel to the ground when a user manually carriers the blower in a normal, elevated operating position by the means for manually carrying.

7. The blower in accordance with claim 6 wherein each of the plurality of bores has axis and whereby the plurality of bores are oriented such that the axes of the bores are substantially parallel to one another and lie substantially within a common plane.

8. The blower in accordance with claim 6 wherein each of the bores has a substantially circular cross-section.

9. The blower in accordance with claim 6 wherein the downstream end of the nozzle further includes means, extending from the nozzle, for scraping objects along the ground.
