  • Patent number: 3999243
    Abstract: A blower to clear obstructions such as leaves from a golf green in preparation to "putting" the ball, comprising a head having a slit to be positioned in proximity to the surface of the green. A tubular shaft extends upwardly from the head and terminates in a housing containing a motor having a fan. Batteries in the housing provide current to operate the motor upon actuation of a switch. The fan causes air to flow through the slit to blow the obstructions from the surface of the green in preparation for "putting" the ball. A brush can be positioned on the head to remove obstructions too heavy to be moved by the air stream.

  • Patent number: 3975930
    Abstract: Yarn is wound back and forth around a given axis to form a tightly wound package, whereupon dye is fed into the bottom of the package, with the axis thereof vertically arranged, and forced to flow radially outwardly through the bottom turns of the package to take up the dye and color at least the lower end of the package. Alternatively, water will first be similarly fed through the package adjacent the bottom thereof, the wicking action of the yarn carrying the water to a level above the top level to which dye is then fed through the yarn in the manner stated. The wicking action of the water prevents the application of the dye from extending above the top level at which the dye is supplied to the package, thus giving a sharp color cut off, whereas with the unwatered package, the application of the dye is such that the wicking action carries the dye to a higher point, the intensity of the color progressively diminishing upwardly.

  • Patent number: 3975790
    Abstract: An ultraviolet lamp fixture used in combination with a conventional, commercial vacuum cleaner for the purpose of purifying the air within a room. The air, after being drawn into the vacuum cleaner and having the dirt particles removed, is exhausted into a U-shaped housing which is carried by the vacuum cleaner and which contains a plurality of longitudinally mounted ultraviolet ray tubes. When the air passes over these tubes, micro-organisms contained in the air are killed by exposure to the ultraviolet radiation emitted from the tubes. The purified air is then returned to the room through an aperture in the housing. The ultraviolet light fixture may be adapted to be used with an existing conventional vacuum cleaner as shown in this specification, or a new combination light fixture-vacuum cleaner may be manufactured.

  • Patent number: 3972089
    Abstract: A brake drum and shoe assembly duster system in which a cylindrical container having one open end and one closed end is provided with a vacuum fitting at an aperture centrally located in the closed end and a plurality of high pressure air fittings along the inside walls spaced 180.degree. apart so that a quarter turn in each direction from insertion over brake drum and/or shoe assembly causes impingement of compressed air over the entire surface of the brake drum itself. The brake dust disloged by the high pressure air is then removed through the vacuum fitting in the center of the bottom of the cylindrical container. Adapter rings are provided for utilization of the container of the system with different sized brake drums.

  • Patent number: 3965524
    Abstract: A residual toner removing apparatus comprises a rotatable cleaning brush enclosed by a casing plate and a restriction board except for two gaps housed in a housing with an opening adjacent to a known photoreceptor surface. During rotation, brush hairs contact the casing plate to charge it with an opposite polarity to that of the toner particles, while the brush hairs are compressed by the restriction board, the cleaning brush thus acting like a fan for circulation of air and entrained toner particles, during which circulation lighter toner particles are attracted by the casing plate with heavier particles falling into catchment portions on the casing and well portions at lower parts of the housing for efficient removal of toner particles without separate vacuum means.

  • Patent number: 3964925
    Abstract: Apparatus for cleaning carpets is provided. The apparatus includes a nozzle for applying liquid such as water to the carpet and also includes air nozzles or openings for drying the carpet. Specifically, a vacuum nozzle is employed to pull in air and water from the carpet, with a hose connecting the vacuum nozzle to a vacuum tank which is associated with a vacuum blower. An exhaust air nozzle or opening is positioned near the vacuum nozzle, with a hose connecting this nozzle to an exhaust outlet associated with the vacuum blower. The vacuum nozzle and the exhaust air nozzle or opening are positioned so that warm exhaust air from the vacuum blower is emitted from the exhaust air nozzle or opening, passes at least partly through the carpet, and is at least partly returned with water through the vacuum nozzle to the tank. In one form, the exhaust air nozzle or opening can be opened and closed remotely through suitable linkages.

    Abstract: A cleaning device for cleaning wall rugs and the like is disclosed. It comprises a cleaning head, a rigid tube and means for connecting the cleaning head to the rigid tube to permit relative movement between the head and the rigid tube. The head has a fluid discharge open end enclosure for applying cleaning fluid to a rug surface throughout a first area and an annular opening substantially surrounding the open end of the discharge enclosure through which a vacuum is applied to the rug surface throughout a second area. The spent cleaning solution passes through the annular opening to a vacuum source regardless of direction of movement of the cleaning head while it is in contact with the rug surface to be cleaned.
