  • Patent number: 4644606
    Abstract: The present invention is directed to an internal combustion engine-powered, blower/vacuum device. The device has an air chamber with an axial air inlet and a tangential air outlet. The engine rotatably drives the impeller, and is controlled by a throttle. A handle is located above the air chamber and the motor, and includes a first section having an axis generally parallel to the axis of the air outlet, and an adjoining section having an axis which extends at an angle of about 15.degree. to 60.degree. to the first section. When the first section of the handle is gripped by an operator the device will be in the vacuum position with the air outlet in a generally horizontal position. When the second section of the handle is gripped, the device will be in the blower position with the air outlet facing ahead of the operator at a downward angle. The impeller and housing of the device is designed to minimize debris hangup within the housing.

  • Patent number: 4624027
    Abstract: An improved movable control for a self-propelled upright vacuum cleaner. The control includes a sleeve longitudinally movably mounted on the distal end of the upright handle of the vacuum cleaner and includes locking structure for retaining the sleeve in a center neutral position, wherein the drive of the nozzle wheels is maintained in a neutral condition. The locking structure is readily manipulatible to release the sleeve from the neutral position when desired and permit it to be moved in opposite directions so as to effect corresponding forward or rearward operation of the drive. The sleeve is maintained relatively short while yet providing a long travel in providing facilitated user control of the drive operation. The sleeve is provided in two halves which are secured together by an improved securing arrangement. In one form, the locking structure is pivotable about an axis parallel to the handle end portion, and in another form, the locking means is pivotable about an axis transversely thereto.

  • Patent number: 4598440
    Abstract: The disclosure relates to an electric buffing machine which is equipped with an X-shaped buffing pad that is mounted to a similarly X-shaped pad holder. The arms of the pad holder have a wedge-shaped cross section that acts as an air foil to create air currents that flow up between the arms of the X-pad. The casing surrounding the pad has a specially designed tunnel-like spiral diffuser that guides the air currents entered into a collection box. The casing also has a flexible skirt mounted to the lower side thereof, extending around three-quarters of the casing periphery, which closes the gap between the casing and the floor. The chassis has two pairs of wheels and is designed so that when the buffing machine is turned off, the machine rests entirely on the wheels with the buffing pad raised off the ground. When the machine is turned on, the air currents pull the pad to the floor with a predetermined pressure.
