Abstract
Abstract A radial arm saw guard for the exposed lower portion of the blade has inner and outer lengths of articulated links fixed to the blade housing to hang on each side of the blade. Each length has a pair of straight links pivotally connected to the front and back of a side of the housing with at least five intermediate links therebetween. The intermediate links are laterally offset a distance equal to their thickness and they are joined by pins extending through longitudinal slots in their ends. Each pin mounts a plastic disk on the side away from the blade, the disks having a diameter at least fifty per cent greater than the vertical depth of the links.

Claim 1
Independent Claim
228 words
A guard for use with a radial arm saw having a motor, a blade driven by and mounted on said motor, and a housing mounted on said motor from which said blade projects downward, said housing having a front and a back and a motor side and an outer side, said guard comprising, in combination, endmost links each containing an elongated longitudinal slot at one end and an aperture at the other end, fastening means projecting from the front and back of said housing on the motor and the outer side, each of said fastening means slidably extending through the longitudinal slot of one of said endmost links slidably securing said endmost links to said housing, intermediate links each containing longitudinal slots at the ends thereof and each having a center containing a lateral offset equal to the thickness of said intermediate links, plastic disks having a diameter at least fifty per cent greater than the vertical thickness of said intermediate links, and pins connecting at least five intermediate links between each pair of said endmost links forming a length of articulated links on each side of said housing, said lengths hanging on each side of said blade and articulating in the plane of said blade, each of said pins mounting one of said plastic disks thereon on the sides of the lengths disPosed away from said blade.
Claim 2
Dependent Claim
