Abstract

A portable engine-operated working machine includes a pair of frame members each having at least a horizontal top bar and a pair of vertical bars extending downwardly from the opposite ends of the horizontal top bar, a bottom cover interconnecting the lower ends of the frame members, a carrying handle interconnecting the horizontal top bars of the frame members, an engine supported on the bottom cover, and a working unit supported on the bottom cover adjacent to the engine.

Claims

1. A hand carriable portable engineoperated working machine comprising:

an engine and a working machine coupled to said engine and driven thereby;

a pair of transverse frame members for supporting for carrying said engine and said working machine attached to and driven said engine, each member of said pair of transverse members having at least a transverse horizontal top bar and a pair of vertical bars integral with and extending downwardly from the opposite ends of said transverse horizontal top bar;

a bottom member interconnecting the lower ends of said frame members;

said engine and said working machine being mounted on said bottom member; and

a carrying handle for lifting, through said transverse frame members, and for carrying said engine and said working machine mounted on said bottom member, said handle extending in the longitudinal direction and being connected at its opposite ends to said transverse top bars of said frame members.

2. A portable engine-operated working machine according to claim 1, including front and rear covers for covering front and rear open spaces between said frame members, and lateral covers for covering lateral open spaces in said frame members.

3. A portable engine-operated working machine according to claim 1, including a fuel tank, said frame members each having brackets positioned below said transverse horizontal top bars for supporting said fuel tank, wherein said fuel tank has opposite ends supported by said brackets between said transverse horizontal top bars of said frame members.

4. A portable engine-operated working machine according to claim 3, wherein said brackets include vibration absorbing means.

5. A portable engine-operated working machine according to claim 1, wherein at least one of said frame members has integral attachment points and a control panel supporting exposed indicators and control members attached to said frame member attachment points.

6. A portable engine-operated working machine according to claim 1, wherein each of said transverse frame members including a support projection coupled to said transverse horizontal top bar, and wherein said carrying handle is coupled to said support projections.

7. A portable engine-operated working machine according to claim 6, wherein each of said support projections includes means for engaging said handle.
