US Patent:

42587638, Mar 31, 1981

Filed:

Nov 20, 1978

Appl. No.:

5/962289

Inventors:

Fernando Figueredo - Key Biscayne FL
Guillermo A. Valdes - Miami FL
Armando R. Framil - Key Biscayne FL

International Classification:

A01G 2308

US Classification:

144 34R

Abstract:

A plurality of cutting teeth are disposed at intervals in a complete circle around the periphery of a flexible cutting element. A frame is coupled to the cutting element to receive and guide the cutting element. Means is coupled to the cutting element and to the frame to impart an oscillatory motion to the cutting element to enable the oscillating teeth of the cutting element to cut a selected material. A simplified version of the present invention includes first and second handles coupled to opposite ends of the flexible cutting element to enable an operator to impart an oscillatory motion to the cutting element.

International Classification:

A01G 2308

US Classification:

144 34R

Abstract:

A cutting apparatus designed to produce an oscillating force which is transmitted to a cutting element, said cutting element having a plurality of cutting teeth disposed at intervals in a complete circle around the periphery of the cutting element. The direction of cutting of the cutting teeth of said cutting element is alternated in opposite directions so that when to the cutting element is applied an oscillatory force, half of the cutting teeth will cut in one direction and the other half in the opposite direction. Thus the cutting apparatus disclosed herein is designed to work with any oscillating flexible cutting element of the type described above.

US Classification:

30166R

Abstract:

A flexible cutting element composed of a plurality of chain links to which are attached tubular cutting units each of which is fabricated with a plurality of cutting teeth protruding upward and disposed at intervals extending radially around the periphery of the cutting unit. The direction of cutting of said cutting teeth are disposed alternately in opposite directions to enable said cutting element to cut a selected material when an oscillating motion is imparted. Various cutting unit designs are presented.
