Filed:

Aug 13, 1979

Appl. No.:

6/066098

Inventors:

Robert I. Feldman - Agoura CA

International Classification:

F16H 114
A01D 3526

US Classification:

74417

Abstract:

A power transmission device adapted to be employed with a chain saw for providing a rotary output in a plurality of directions. The device includes a housing having an input shaft coupled with an output shaft where the input and output shafts are right angles to one another. The housing serves as the support for the driven mechanism and provides mounting flanges about both the input and output shafts. The mounting flange associated with the input shaft cooperates with a chain guideplate to adjustably mount the housing to the chain saw. By simply loosening two screws, the orientation of the output shaft relative to the chain saw can be changed by up to substantially 180 degrees. The mounting flange around the output shaft is designed to allow a 360-degree range in orientation of the driven device about an axis coincident with the axis of the output shaft.

Abstract:

A head for a rotary drive designed for trimming of vegetation. The head includes two circular plates coaxially arranged with pivotally mounted plastic blades positioned on pins between the plates. The blades are held outwardly by centrifugal force but are free to rotate to between the plates when contacting rigid objects. A glide knob extends from the bottom of the head for improved control of the device.
