  • Publication number: 20040237230
    Abstract: A hand-operated sweeping machine having two circular brooms mounted in the front area, a motor drive which rotates the circular brooms, a drive mechanism which transfers a driving force derived from the forward motion of the sweeping machine to drive the circular brooms when the motor drive is not operating, and an interrupting mechanism which automatically interrupts a connection between the motor drive and the driving mechanism when the motor drive can rotate the circular brooms faster than the driving mechanism. When the motor drive of the sweeping machine is inoperative, as when there is no electricity available to operate an electric motor drive, the sweeping machine may be operated by the driving mechanism driving the circular brooms. The interrupting mechanism automatically prevents the motor drive when operating from transferring driving force to the driving mechanism and thereby undesirably driving forward motion of the sweeping machine.

  • Patent number: 6802098
    Abstract: The present invention provides an adjustment mechanism and methods for adjusting the alignment of a powered cylindrical brush mounted to a surface maintenance vehicle relative to a surface to be maintained or cleaned by the vehicle. The device is preferably disposed upon the idler-side of a powered rotating cylindrical brush assembly and the adjustment preferably occurs via use of an eccentric cam member providing a range or motion, or pivot location, through or about which the idler-side mounting location of the cylindrical brush may be adjusted to improve contact with the surface. The present invention enables such adjustment without decoupling the rotating brush from its couplings (both supportive and rotational coupling), and any coupling to a drive mechanism for driving the rotating brush into rotation. The rotating brush so adjusted will benefit from improved mechanical cooperation between the bristles of the brush and the surface to be cleaned.

    Abstract: A rotary brush assembly that is mounted to a traction vehicle, such as a skid steer type vehicle. The brush assembly is allowed to move relative to the traction vehicle within three degrees of freedom including yaw, roll, and up and down linear motion. The degrees of freedom reduce brush wear and facilitate more effective cleaning over uneven surfaces. Up and down linear motion is accommodated by a linear sliding joint. The sliding joint is further equipped with markings that indicate to the operator where, in the range of up and down motion, the brush is located. The brush assembly is also equipped with a mounting mechanism that translates motion of a skid steered vehicle implement arm joint into yaw motion of the brush. This eliminates the need for additional hydraulic cylinders or controls to actuate yaw motion.
