Abstract
The bi-directional saw chain is made up of two links, a cutting link and a connecting link. The cutting link is symmetrical about its vertical center line and includes an L-shaped cutting section having cutting surfaces along both the leading and trailing edges. Legs extend outwardly from the cutting link on either side of the cutting section. These legs terminate in a surface which acts as a depth gauge. Each leg also includes a stop shoulder for engagement with the connecting link. The connecting link includes two offset and parallel sections, each having an outwardly extending flange. The outwardly extending flanges of adjacent connecting links form side by side parallel and spaced flanges which accommodate a perimetric trackway on the saw blade. Each connection is pivotal so that the leading leg acts as the depth gauge and the trailing leg engages the connecting link to form the stop and position the cutting link for proper functioning.
