Abstract:
A guide bar for a chain saw comprising an elongated planar body having a proximal end and a distal end and a pair of opposed long sides, the distal end having a convex rounded profile around which an endless chain changes direction, the proximal end having a profile that enables it to cooperate with a drive sprocket on a drive shaft of a chain saw, the body having a longitudinally extending slot area with a through-slot adjacent the proximal end, the length of the slot being substantially greater than the width of the slot, the slot area being adapted to receive a pair of parallel studs carried by a chassis of a chain saw, a cam follower rigidly attached to the body and projecting perpendicularly from a planar face of the body, the cam follower being located, in a longitudinal direction, at a position between the ends of the slot area and, in a direction perpendicular to the longitudinal direction, between the slot and one of said long sides, and a high friction surface on the face of the body from which the cam follower projects.
