Abstract

Abstract A saw mechanism comprises a work support, a round table rotatably carried on said work support, and a pivot support carried by the table. A guide is mounted on the pivot support for pivotal movement and includes a pair of parallel rods. A saw includes a saw housing and a motor driven blade on the housing. The housing has a pair of passages which slidably receive the rods so that the housing can be adjusted relative to and along the rods.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 219 words
A saw mechanism comprising: a work support including a circular opening and a recess communicating radially with said opening, a circular table rotatably carried in said circular opening of said work support and including an arm with an insertion slit projecting radially into said recess so as to be movable circumferentially within said recess, the circumferential extent of said recess corresponding to the range of the miter cut for the saw mechanism, a pivot support carried by said table, a guide means mounted on said pivot support for rotation about an axis extending generally transversely relative to said slit, said guide means including parallel rods projecting generally transversely relative to said axis, said rods lying in a common plane oriented perpendicularly to the plane of said table, and saw means comprising a saw housing and a motor driven blade rotatably carried by said saw housing for rotation about an axis, said saw housing having passages located directly therein which passages slidably receive said rods such that said saw housing can be adjusted relative to said table along said rods, said passages each disposed in the immediate vicinity of said axis of rotation of said blade and lying in a common plane oriented perpendicularly to said plane of said table in the immediate vicinity of the plane of said blade.
Claim 2
Dependent Claim 219 words
A saw mechanism comprising: a work support including a circular opening and a recess communicating radially with said opening, a circular table rotatably carried in said circular opening of said work support and including an arm with an insertion slit projecting radially into said recess so as to be movable circumferentially within said recess, the circumferential extent of said recess corresponding to the range of the miter cut for the saw mechanism, a pivot support carried by said table, a guide means mounted on said pivot support for rotation about an axis extending generally transversely relative to said slit, said guide means including parallel rods projecting generally transversely relative to said axis, said rods lying in a common plane oriented perpendicularly to the plane of said table, and saw means comprising a saw housing and a motor driven blade rotatably carried by said saw housing for rotation about an axis, said saw housing having passages located directly therein which passages slidably receive said rods such that said saw housing can be adjusted relative to said table along said rods, said passages each disposed in the immediate vicinity of said axis of rotation of said blade and lying in a common plane oriented perpendicularly to said plane of said table in the immediate vicinity of the plane of said blade.
Claim 3
Dependent Claim 21 words
Apparatus according to claim 1, wherein said passages are spaced to opposite sides of said axis of rotation of said blade.
Claim 4
Dependent Claim 28 words
Apparatus according to claim 1, wherein said passages are of such length that said rods remain therein during the entire stroke of the saw housing along said rods.
Claim 5
Dependent Claim 25 words
Apparatus according to claim 1 including spring means for yieldably biasing said guide means to a position maintaining said saw housing in an uppermost position.
Claim 6
Dependent Claim 26 words
Apparatus according to claim 1 including a protective hood overlying an upper portion of said blade, said passages situtated below the uppermost extent of said hood.
Claim 7
Dependent Claim 37 words
Apparatus according to claim 1 including a motor mounted on said saw housing and including an output shaft received in a bearing bore of said housing, said passages being situated on opposite sides of said bearing bore.
Claim 8
Dependent Claim 37 words
Apparatus according to claim 3 including a motor mounted on said saw housing and including an output shaft received in a bearing bore of said housing, said passages being situated on opposite sides of said bearing bore.
Claim 9
Dependent Claim 18 words
