Patent number: 6986344Abstract: A bladeshaft assembly for a cutting saw includes a hollow tubular housing member. A shaft member extends coaxially through the tubular housing member and has at least one end that extends outwardly of the tubular housing member. At least one bearing member is disposed in surrounding relation to a portion of the shaft member. A seal is provided for sealing around the at least one end of the shaft member. A pulley member is mounted on the at least one end of the shaft member that extends outwardly of the tubular housing member. A tapered fit is formed cooperatively between the pulley member and the end of the shaft member so as to enable a press fit relation between the pulley member and the end of the shaft member. Additionally, first and second gauge points are formed respectively between the pulley member and the at least one end of said shaft member; the first and second gauge points engaging one another so as to establish a predetermined placement of the pulley member on the end of the shaft member.Type: GrantFiled: February 13, 2004Date of Patent: January 17, 2006Assignee: Electrolux Professional Outdoor Products, IncInventors: Donald F. Meister, Michael G. Kingsley, Douglas Dempsey

Patent number: 5810448Abstract: A concrete saw is provided having an engine aligned along a longitudinal axis of the saw frame to minimize the width of the saw and provide a more balanced system. A clutch assembly is attached to a forward end of the engine to disengage the saw blade without stopping the engine. A right angle gear box is provided proximate the driven side of the clutch assembly to transfer driving rotational forces from the engine to a transversely aligned driven shaft. The driven shaft includes drive pulleys mounted upon opposite ends thereof, which are aligned with driven pulleys mounted upon opposite ends of a blade support shaft and linked to one another via multiple belts. This alignment evenly balances the load transfer while facilitating the use of vibration isolators between the engine, gear box and frame. A hydraulically controlled depth stop mechanism is included for setting a maximum cut depth. The engine speed is controlled by an electronic governor.Type: GrantFiled: December 23, 1996Date of Patent: September 22, 1998Assignee: Diamant Boart, Inc.Inventors: Michael G. Kingsley, Kevin R. Wilson, Donald F. Meister

Patent number: 5743247Abstract: A concrete saw is provided which utilizes a transmission having both forward and reverse, high and low speed ranges separated by a neutral state. The transmission includes a neutral start switch which prevents the engine from being started, while the transmission is in gear. An automatic parking brake assembly is mounted to the frame proximate the drive wheel. The brake assembly fixedly engages the drive wheel when the ignition switch is turned to the off position, when the battery is disengaged or when the battery is dead. The brake assembly also immobilizes the drive wheel whenever the transmission is shifted to the neutral state regardless of the position of the ignition switch. The system is provided with an override switch to bypass the automatic application of the brake assembly when the transmission is placed in neutral to facilitate winching or otherwise rolling the saw without engine power. Normally, the brake assembly disengages when the transmission is shifted from neutral into gear.Type: GrantFiled: September 15, 1995Date of Patent: April 28, 1998Assignee: Diamant Boart, Inc.Inventors: Michael G.
