Abstract
Abstract A portable power saw apparatus is disclosed having an endless saw chain driven about a bow bar by an internal combustion engine. The apparatus includes a pair of transversely spaced legs respectively secured to the chain guide adjacent the outer end thereof and extending downwardly therefrom. The legs provide a ground-engageable abutment to support the outer end portion of the chain guide and saw chain, and they also define a size guage determinative of the largest diameter object acceptable between the legs for severance by the saw chain. Skid means secured to the handle structure of the apparatus is oriented at substantially the same elevation as the legs and forms a ground-engageable means therewith to support the saw apparatus in a generally horizontal orientation in certain operating modes.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
160 words
A portable power saw apparatus having in combination a casing assembly, a chain guide extending longitudinally therefrom and transversed along the edges thereof by an endless power driven saw chain, and a handle structure enabling said apparatus to be hand-held and manipulated the improvement comprising: a pair of legs secured to the chain adjacent the outer end-portion thereof remote from the casing assembly and extending laterally from the guide, said legs disposed in transversely spaced relation to define a size guage determinative of the largest diameter object accepted between said legs for severance by the chain saw, said legs' end portions forming a wide mouth to facilitate movement of severable objects through the spaces defined between said legs and into engagement with said saw chain, said legs providing a ground-engageable abutment in at least one operative position to support the outer end portion of the chain guide and saw chain and protect the same from groundengagement during certain cutting operations.
Claim 2
Dependent Claim
160 words
A portable power saw apparatus having in combination a casing assembly, a chain guide extending longitudinally therefrom and transversed along the edges thereof by an endless power driven saw chain, and a handle structure enabling said apparatus to be hand-held and manipulated the improvement comprising: a pair of legs secured to the chain adjacent the outer end-portion thereof remote from the casing assembly and extending laterally from the guide, said legs disposed in transversely spaced relation to define a size guage determinative of the largest diameter object accepted between said legs for severance by the chain saw, said legs' end portions forming a wide mouth to facilitate movement of severable objects through the spaces defined between said legs and into engagement with said saw chain, said legs providing a ground-engageable abutment in at least one operative position to support the outer end portion of the chain guide and saw chain and protect the same from groundengagement during certain cutting operations.
Claim 3
Dependent Claim
31 words
The apparatus of claim 1 in which said legs are removably secured to the chain guide to enable said legs defining variant sized gauges to be interchangeably associated with said apparatus.
Claim 4
Dependent Claim
28 words
The apparatus of claim 1 which additionally comprises an electric light means secured to said casing assembly and oriented to direct a beam of light toward said legs.
Claim 5
Dependent Claim
103 words
A portable power saw apparatus in accordance with claim 1 in which the chain guide comprises a pair of transversely spaced diverging members extending longitudinally and forwardly from the casing assembly and haing an arcuate bent portion connecting the forward ends of the diverging members, the chain saw being guided along the outer edges of the members and of the arcuate connecting portion, said legs secured to an extending forwardly and divergently from said members and beyond the arcuate connecting portion, and the portion of the legs, extending beyond the arcuate connecting portion of the diverging members being laterally spaced from said members.
Claim 6
Dependent Claim
32 words
The apparatus of claim 1 in which each of said legs is generally U-shaped, extending laterally from said chain guide in one direction, forwardly therefrom, and then laterally in the opposite direction.
