International Classification:

1503

US Classification:

D15 11, D15 17

US Patent:

7743839, Jun 29, 2010

Filed:

Mar 6, 2009

Appl. No.:

12/381122

Inventors:

Brent Peterson - Buffalo Grove IL, US

Assignee:

Echo, Incorporated - Lake Zurich IL

International Classification:

A01D 34/00

US Classification:

172 15

Abstract:

An edger having a main frame that can be advanced controllably relative to subjacent terrain, a cutting assembly on the main frame, and a drive for rotating the cutting assembly around a first axis. The cutting assembly has a plurality of cutting teeth that dig into underlying terrain as the cutting assembly is operated to thereby cooperatively produce a trench in the underlying terrain. The plurality of cutting teeth includes a first cutting tooth that has an elongate configuration with a leading end and a length extending along a first line. The first cutting tooth is oriented on the cutting assembly so that the length of the first cutting tooth traces a path with a circumference that has a radial extent with respect to the first axis that is substantially less than the length of the first cutting tooth. The length of the first cutting tooth is aligned generally in a circumferential direction.

International Classification:

A01G 3/04

US Classification:

30220, 30216

Abstract:

A trimmer having a first cutting blade and a second cutting blade. A first drive gear assembly cooperates with the cutting blades so that as the first drive gear assembly rotates around a first axis, the cutting blades are caused to reciprocatingly move in first and second paths to produce a cutting action. A second drive gear assembly has a second drive gear that has teeth in mesh with teeth on the first drive gear assembly. The second drive gear is rotatable around a second axis to cause the first drive gear assembly to be rotated in the first rotational direction. A powered drive assembly rotates the second drive gear around a second axis in the one rotational direction. The teeth on the first drive gear assembly are defined by a first bevel gear. The second gear is a bevel gear in mesh with the first bevel gear.

Inventors:

Brent Peterson - Buffalo Grove IL, US

Assignee:

Echo, Incorporated - Lake Zurich IL

International Classification:

A01D 34/00

US Classification:

172 15, 172 17, 172 41

Abstract:

An edger has a main frame that can be advanced controllably relative to a subjacent terrain, a cutting assembly on the main frame, a drive for rotating the cutting assembly around a first axis, and material repositioning structure on at least one of the main frame and cutting assembly. The cutting assembly is configured to produce a trench in underlying terrain as the cutting assembly is rotated by the drive in operation. The material repositioning structure controllably repositions material dislodged from underlying terrain by the cutting assembly to thereby avoid accumulation of dislodged material upon the edger as the edger is operated.

Inventors:

Brent Peterson - Buffalo Grove IL, US

International Classification:

A01G 3/00
A01D 34/00

US Classification:

30519, 302754, 30122, 294011

Abstract:

A portable powered tool has a frame, a working component on the frame for performing an operation, a drive on the frame for operating the working component, a shaft having a first output portion that is driven by the drive around a first axis to thereby cause operation of the working component, and a transmission assembly operatively connected to the first output portion of the shaft to transmit a drive force from the first output portion to the working component to thereby cause operation of the working component.

Appl. No.:

12/911077

Inventors:

Brent Peterson - Buffalo Grove IL, US

International Classification:

F04D 29/40

US Classification:

415200

Abstract:

A portable blower having a propulsion unit for continuously generating a supply of pressurized fluid and a conduit assembly for controllably directing fluid from the propulsion unit to and through a discharge opening on the conduit assembly. The discharge opening is bounded by a rim, defined at least partially by a discrete component made from a first material. The conduit assembly has a first portion made from a second material to which the discrete component is operatively connected. The first material is at least one of: a) more resistant to abrasive wear than the second material; b) more resistant to impact than the second material; and c) harder than the second material.

International Classification:

F04D 29/44

US Classification:

4152082

Abstract:

A portable fluid blower with a housing having a central axis and defining a fluid flow path extending axially between an upstream inlet and a downstream outlet. A fan assembly has a rotary component that is operable to draw fluid into a first stage of the flow path and accelerate fluid incoming at the inlet radially outwardly to against a first housing surface portion that diverts the fluid to a second stage of the flow path. The second flow path stage is defined by facing second and third housing surface portions that cause the fluid to flow substantially fully axially in an annular space extending around the central axis between the first stage and a third stage. The fluid flows from the third stage to and through the downstream outlet.

Inventors:

Brent Peterson - Buffalo Grove IL, US

International Classification:

B27B 17/14
B23D 57/02

US Classification:

30386

Abstract:

A saw having a power unit with a drive component and a housing for the power unit with a frame. A bar on the housing guides movement of an operatively positioned cutting chain driven by the drive component in an endless path. The bar is movable guidingly in opposite directions in a predetermined path relative to the housing to thereby vary tension upon an operatively positioned cutting chain. A bar fixing assembly has a knob that is turnable around a first axis relative to the housing in: a) a first direction to a tightened state; and b) a second direction to a loosened state. A first assembly resiliently bears against the knob to at least one of: a) inhibit turning of the knob around the first axis; b) provide a sensory indication to a user grasping and turning the knob that the knob is moving around the first axis; and c) reduce play in the knob.
