Abstract
Abstract A radial saw including a table with a work support surface to which a frame is connected below the work support surface. A post is connected to the frame at the rear thereof, and a support arm cantilevers over the table from its post connection. A pair of support rods, one round and one square are affixed to the support arm. A slide is fitted with bearings that will separately journal the round rod in close fit and the square rod in loose fit. A motor for the saw is carried by the slide to be moved therewith in translatory motion across the work support surface. The frame and the post are each angularly adjustable to permit selective straight cutting, or various miter and compound angle cuts.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
170 words
A radial saw comprising: (a) a table having a work support surface, (b) a frame connected to the table and disposed under the work support surface, (c) a post connected to the frame remote from the table, (d) a support arm connected to the post to cantilever over the work support surface, (e) a pair of support rods, one round and one square, affixed to the support arm, (f) a slide means holding a pair of bearings, (g) one of the bearings being formed with a cylindrically shaped bearing surface arranged to embrace the round rod in close fit for sliding motion thereon, (h) the other bearing being formed with a rectangularly shaped bearing surface arranged to embrace the square rod in loose fit in the direction toward and away from the round support rod and a close fit in the direction perpendicular thereto for sliding motion thereon, and (i) a saw motor carried by the slide means to be moved therewith in translatory motion across the work support surface.
Claim 2
Dependent Claim
170 words
A radial saw comprising: (a) a table having a work support surface, (b) a frame connected to the table and disposed under the work support surface, (c) a post connected to the frame remote from the table, (d) a support arm connected to the post to cantilever over the work support surface, (e) a pair of support rods, one round and one square, affixed to the support arm, (f) a slide means holding a pair of bearings, (g) one of the bearings being formed with a cylindrically shaped bearing surface arranged to embrace the round rod in close fit for sliding motion thereon, (h) the other bearing being formed with a rectangularly shaped bearing surface arranged to embrace the square rod in loose fit in the direction toward and away from the round support rod and a close fit in the direction perpendicular thereto for sliding motion thereon, and (i) a saw motor carried by the slide means to be moved therewith in translatory motion across the work support surface.
Claim 3
Dependent Claim
142 words
A radial saw as set forth in claim 1 in which: (a) the post is pivotably connected to the frame, (b) a bracket is formed on the frame adjacent to the post, (c) an arcuate slot is formed on one side of the post above the pivotal connection, (d) a clamping means extends through the slot to connect the post to the frame at a predetermined vertical angle of cut, and (e) the cylindrical bearing embracing the round guide rod in a close fit maintains a predetermined cutting line of the radial saw in any vertical angle of cut and the rectangular bearing embracing the square rod in a close fit perpendicular to the direction toward and away from the round support rod provides for predetermined angular orientation of the cutting line of the radial saw in any vertical angle of cut.
