ABSTRACT:
A highly stable concrete saw for cutting crack control relief grooves features a stabilized and reinforced carriage. The carriage frame comprises a generally C-shaped, rigid metal weldment having a closed side extending between a closed front and closed rear. The opposite side is partially open at the bottom, but closed at the top by an elevated reinforcing bridge that connects the front and rear of the frame. The frame substantially surrounds and pivotally captivates a rigid subframe supporting the drive motor and the blade assembly. The carriage comprises a pair of rigid, inwardly offset and downwardly projecting tabs at its front and rear. The tabs are line bored to journal elongated axles that mount front and rear pairs of resilient rollers. Angled scraper assemblies projecting downwardly in front of each pair of rollers deflect away loose debris to maintain a smooth travel path for the carriage. A belt driven axle terminating in an arbor disposed at the open side of the frame supports a rotary cutting blade. The blade is shrouded by a pivotally displaceable guard that mounts a forwardly projecting roller wheel that is normally firmly biased against the concrete surface. Saw alignment is aided with a deflectable pointer that normally follows the intended cutting path. A controlling handle assembly projects from the carriage rear for saw control. A handle-mounted control cable extends to the motor for pivoting the subframe to adjust blade cutting depth.
