Abstract
Abstract A chain saw adapted to damp mechanical vibrations comprising a front handle attached to the front portion of the engine section through a plurality of vibration dampers made of rubber or like material, a connector made of a rigid material connected to the front handle and disposed downwardly of the engine section to extend rearwardly thereof, and a rear handle attached to the upper portion of the rear wall of the engine section through at least one vibration damper made of rubber or like material. The connector is connected at its rear end portion to the rear handle through a vibration damper made of rubber or like material and at its intermediate portion to the underside of the engine section through a vibration damper made of rubber or like material.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
181 words
A portable type chain saw having separate front and rear handles which are attached respectively to front and rear portions of the main body of the chain saw engine in a manner that mechanical vibration caused by the engine-operation may be absorbed characterized in that said front handle is attached to a front portion of the main body of the chain saw engine through vibration dampers of rubber or the like elastomeric material, said rear handle is attached to an upper rear wall of said main body through vibration dampers of rubber or the like elastomeric material; said front and rear handles are connected together by means of a rigid unitary connector extending longitudinally of said main body at the lower side thereof; said connector having a front end portion attached to a lower portion of said front handle, an intermediate portion attached to a lower rear portion of said main body through vibration damper of rubber or the like elastomeric material and a rear end portion extending rearwardly beyond said main body and attached to said rear handle through vibration
Claim 2
Dependent Claim
181 words
A portable type chain saw having separate front and rear handles which are attached respectively to front and rear portions of the main body of the chain saw engine in a manner that mechanical vibration caused by the engine-operation may be absorbed characterized in that said front handle is attached to a front portion of the main body of the chain saw engine through vibration dampers of rubber or the like elastomeric material, said rear handle is attached to an upper rear wall of said main body through vibration dampers of rubber or the like elastomeric material; said front and rear handles are connected together by means of a rigid unitary connector extending longitudinally of said main body at the lower side thereof; said connector having a front end portion attached to a lower portion of said front handle, an intermediate portion attached to a lower rear portion of said main body through vibration damper of rubber or the like elastomeric material and a rear end portion extending rearwardly beyond said main body and attached to said rear handle through vibration
Claim 3
Dependent Claim
50 words
A portable type chain saw as defined in claim 1, wherein said front handle is attached through said vibration dampers to said main body of the chain saw engine at at least two positions substantially spaced apart from each other transversely of said chain saw, and said connector is rigidly
Claim 4
Dependent Claim
37 words
A portable type chain saw as defined in claim 1, wherein said front handle is connected to said main body of the chain saw engine through a vibration damper having a substantial width transversely of said chain
Claim 5
Dependent Claim
194 words
A portable type chain saw having separate front and rear handles which are attached respectively to the front and rear portions of the main body of the chain saw engine in a manner that mechanical vibration caused by the engine operation may be absorbed characterized in that said chain saw comprises a unitary rigid connector extending longitudinally of said main body at the lower side thereof so as to connect said front handle with said rear handle, said connector being attached at a forward portion thereof to a lower front section of said main body through vibration damper of rubber or the like elastomeric material, at an intermediate portion thereof to a lower rear section of said main body through vibration damper of rubber or the like elastomeric material and at a rear end portion thereof to a lower rear end portion of said rear handle through vibration damper of rubber or the like elastomeric material; said front handle being attached to the front end portion of said connector, said rear handle being attached to the upper rear wall of said main body of the chain saw engine through vibration damper of rubber or
Claim 6
Dependent Claim
194 words
A portable type chain saw having separate front and rear handles which are attached respectively to the front and rear portions of the main body of the chain saw engine in a manner that mechanical vibration caused by the engine operation may be absorbed characterized in that said chain saw comprises a unitary rigid connector extending longitudinally of said main body at the lower side thereof so as to connect said front handle with said rear handle, said connector being attached at a forward portion thereof to a lower front section of said main body through vibration damper of rubber or the like elastomeric material, at an intermediate portion thereof to a lower rear section of said main body through vibration damper of rubber or the like elastomeric material and at a rear end portion thereof to a lower rear end portion of said rear handle through vibration damper of rubber or the like elastomeric material; said front handle being attached to the front end portion of said connector, said rear handle being attached to the upper rear wall of said main body of the chain saw engine through vibration damper of rubber or
Claim 7
Dependent Claim
55 words
A portable type chain saw as defined in claim 4, wherein the connection of said connector to the lower front section of said main body is made by means of at least two vibration dampers of rubber or the like elastomeric material which are substantially spaced with each other in transversely of the chain saw.
