Abstract
Abstract A rotary saw, such as a masonry saw includes a rocker platform supporting a rotating saw blade and blade driving elements, the platform being pivoted to the saw frame and spaced above a work piece table surface. A saw hood partially covers the blade and is pivotally mounted on the platform by an external curved band or segment engaging multiple grooved rollers. A pivotal link connects the hood to a standard mounted on the saw frame and maintains the lower edge of the hood in a horizontal attitude regardless of platform tilt angle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
157 words
A hood leveling structure for use with a rotary saw comprising: a. a frame, a platform pivoted on said frame for rocking motion, said platform including a shaft housing containing shaft bearings, a driven shaft rotatably supported by said bearings, a saw blade mounted on said shaft, b. a hood partially coVering said saw blade and having a lower edge spaced inwardly of the periphery of said saw blade, c. mounting means operably positioned between said hood and platform and including an arcuate rail member having spacedapart ends and opposed semi-circular edges between said ends, said semi-circular edges being remote from said shaft housing, said mounting means further including a plurality of support means movably engaging said semi-circular edges between said support means and permitting guided pivoting between said hood and platform, and d. link means engaged between said hood and frame for maintaining said lower edge in a substantially level position during pivoting of said platform.
Claim 2
Dependent Claim
157 words
A hood leveling structure for use with a rotary saw comprising: a. a frame, a platform pivoted on said frame for rocking motion, said platform including a shaft housing containing shaft bearings, a driven shaft rotatably supported by said bearings, a saw blade mounted on said shaft, b. a hood partially coVering said saw blade and having a lower edge spaced inwardly of the periphery of said saw blade, c. mounting means operably positioned between said hood and platform and including an arcuate rail member having spacedapart ends and opposed semi-circular edges between said ends, said semi-circular edges being remote from said shaft housing, said mounting means further including a plurality of support means movably engaging said semi-circular edges between said support means and permitting guided pivoting between said hood and platform, and d. link means engaged between said hood and frame for maintaining said lower edge in a substantially level position during pivoting of said platform.
Claim 3
Dependent Claim
28 words
A hood leveling structure as set forth in claim 1 wherein: a. said support means comprise multiple rollers and a bracket securing said multiple rollers to said platform.
Claim 4
Dependent Claim
21 words

Claim 5
Dependent Claim
63 words
A hood leveling structure as set forth in claim 1 wherein: a. said arcuate rail member is a segment secured to said hood with said semi-circular edges forming inner and outer rails, and b. said support means are multiple rollers secured to said platform and engaging said rails for supporting said hood while permitting relative pivoting movement between said hood and said housing.
Claim 6
Dependent Claim
99 words
A hood leveling structure as set forth in claim 1 wherein: a. said link means for maintaining the lower edge of said hood in a substantially level position includes: b. a standard extending from said frame and a leveling arm extending between and having opposite ends thereof pivotally connected to said standard and to said hood, c. said leveling arm being connected to said hood by a quick-disconnect anchor, d. said rail member ends being positioned for rotating beyond and out of engagement with said support means upon relative movement between said hood and platform, thereby freeing said hood.
