Appl. No.:

11/339209

Inventors:

William Bradley Mace - Spring Grove IL, US
Ronald A. Carlson - Elgin IL, US

International Classification:

B26B 19/02
B26B 19/04

US Classification:

30216, 30220, 30223, 30224, 83837, 56236, 411432, 411533

Abstract:

A trimmer having first and second cutting blades. The first and second cutting blades are mounted so that first and second flat surfaces, respectively thereon, face and are substantially parallel to each other. A drive causes at least one of the first and second cutting blades to move relative to the other of the first and second cutting blades. At least one fastening assembly has first and second facing shoulders between which the first and second cutting blades reside. The at least one fastening assembly further has at least one biasing element that produces a force that biasably urges the first and second flat cutting blade surfaces towards each other.

International Classification:

B27B 17/02

US Classification:

30381, 302961, 464 52, 464 53

Abstract:

A powered apparatus having an elongate pole, a drive at a proximal region of the elongate pole and operable to rotate a first component on the drive, a tool at a distal region of the elongate pole with a second component that is rotatable to operate the tool, and a power transmission assembly for transmitting a drive force generated by rotation of the first component to the second component to thereby operate the tool. The power transmission assembly has a flexible drive link with a flexible length located between the drive and at least one other substantially inflexible drive part that is downstream of the drive link. The flexible length of the flexible drive link is greater than four (4) inches.

International Classification:

B25G 1/00
B23D 57/02

US Classification:

30381, 302774, 81489

Abstract:

A powered apparatus having an elongate pole with a tool at a proximal region and a drive for operating the tool. A first operating component is repositionable between first and second positions to change a state of the drive. A second operating component is repositionable between: a) a locked position; and b) a released position wherein the first operating component can be changed from the first position into the second position. A handle assembly has a gripping portion with an extent that can be grasped by the user's one hand at a plurality of different locations along the extent of the gripping portion to control the operating components, including at a first location in a manner wherein with the elongate pole vertically oriented, a majority of a vertical weight force component of the apparatus is directed generally parallel to the length of a user's forearm below the user's one hand.
