Resiliently Biased Patents (Class 401/278)
  • Patent number: 4895468
    Abstract: A brush with automatic water shut-off is disclosed. The brush includes a handle portion pivotally connected to a body portion with a valve chamber intermediate to control water flow through the brush. A flutter valve is loosely positioned within the valve chamber and is continuously biased toward the valve chamber seat by the water pressure. An operating rod is movable within the body portion and extends past the plane of the seat. When the brush is not in use, water pressure forces the flutter valve toward the seat and contact between the flutter valve and the operating rod causes the body portion and handle portion to be pivotally offset with no water flowing. When the brush bristles contact the surface to be cleaned, the body and brush portions are urged into axial alignment about the pivot whereby the operating rod will force the flutter valve off of its seat, thereby automatically causing water flow through the brush.

  • Patent number: 4883204
    Abstract: A manually-operated dispenser for user-controlled discharge of an internally-stored fluid includes a variable length assembly normally driven to its maximum longitudinal extension for substantially closing a fluid discharge opening and for fluid-tightly closing a vent opening disposed at opposite ends of an elongated housing, the fluid discharge opening being normally sufficiently closed so as to prevent discharge of stored fluid through the discharge opening but permitting predetermined bleeding of fluid from the housing interior through the discharge opening, a piston bounding an end of an internal fluid reservoir and operatively movable along the housing for volumetrically reducing the reservoir and for driving stored fluid toward and through the discharge opening, and an actuator assembly manually operable by the user for causing controlled foreshortening of the variable length assembly whereby the fluid discharge and vent openings are concurrently opened permitting the forced discharge of a corresponding

  • Patent number: 4764044
    Abstract: A writing instrument or an applicator of the invention is constructed of: a shaft sleeve main body having an application liquid reservoir therein; and an application member provided in a front end of the shaft sleeve main body to receive a liquid supplied from the liquid reservoir. The shaft sleeve main body comprises: an ink conduit member provided with a large-diameter piston portion, and a rod element which projects forward from the piston portion and is smaller in diameter than the piston portion while provided with a communication-hole; a cylinder member for slidably receiving the ink conduit member means for moving the cylinder member along the axial line of the shaft sleeve main body; means for biasing both the cylinder member and the ink conduit member so as to be separated from each other; and a hole for the application member, connected to a front end portion of said ink conduit member, which front end portion projects from the cylinder member.

  • Patent number: 4674904
    Abstract: A brush for use in a self service car wash having an applicator head containing cleaning bristles and an elongated tubular handle adapted to bring wash fluids to the head. A relief valve is positioned in the handle which is designed to open when the fluid pressure in the handle exceeds a given value. A control valve is located between the relief valve and automatic fluid dispensing equipment for delivering fluids to the brush during a wash cycle. A bypass is provided in the control valve that permits water to drain into the handle when the control valve is closed, as for example between wash cycles. Pressure thus builds up in the handle behind the relief valve whereupon the valve periodically opens to relieve the pressure.

  • Patent number: 4655627
    Abstract: A brush arrangement, specifically a toothbrush, is provided with a reservoir of cleaning material in its handle. The handle is hollow and provided with an actuatable plunger arrangement which pressurizes the cleaning material so as to force it through a channel and to the brush head. The pressurized cleaning material opens a pressure valve arrangement which exposes a dispensing port through which the cleaning material is dispensed in the vicinity of a plurality of bristles. The dispensing port is opened by the application of a force from the pressurized cleaning material which exceeds a counterforce applied by a resilient device, such as a spring. When the pressure in the reservoir is relieved, such as by reversing the direction of travel of the plunger, the counterforce applied by the spring is sufficient to ensure that the pressure valve closes the dispensing port. In certain embodiments, the brush arrangement is provided with a replaceable brush head.

  • Patent number: 4319852
    Abstract: A material dispensing brush having a substantially rigid holding chamber and a resiliently, deformable bulb attached to the chamber for the purpose of pressurizing the same. The bulb is positioned proximate to the handle of the brush so that an operator may use his thumb to depress the bulb and thus increase the air pressure within the holding chamber so as to effect an ejectment of treatment material outwardly from the chamber through a plurality of dispensing orifices extending through the bristle retaining portion of the brush. The dispensing orifices have a truncated shaped portion proximate to the holding chamber so as to facilitate the delivery of the treatment material into the orifices during a pressurization of the chamber.

  • Patent number: 4312598
    Abstract: This appliance which provides instantaneous cleaning and immediate drying comprises a handle, at one end of which is hinged a heating sole protected by a cover, in combination with a swab made from any absorbing material held under this heating sole as well as with means for feeding water to the lower face of the heating plate in contact with the swab. The heating sole- protecting cover assembly has at least one opening, and said means are formed by a water reservoir placed above said cover and comprising at least one appendage housed in said opening, this appendage having at its base at least one flow orifice for the water. Means such as a piston and springs are provided for maintaining this orifice normally closed and for opening it when it is desired to damp the swab in contact with the heating sole.

  • Patent number: 4181997
    Abstract: A tooth-brushing device comprising a brushing unit provided with rotating brushes, and a dentifrice-carrying cartridge unit. The cartridge unit is attachable to a water faucet and supports an impeller operated by water pressure to rotate the brushes. The cartridge unit also has a passage for conducting water from the faucet to the rotating brushes. The cartridge unit supports a disposable dentifrice tube which is squeezed by the pressure of water from the faucet to force dentifrice from the tube to the brushes.

  • Patent number: 4043681
    Abstract: In a writing instrument comprising a writing core and an ink tank, the contact of the writing core with the ink in the ink tank is intercepted so that unnecessary loss of the ink due to evaporation from the core surface and excessive supply of the ink to the core are effectively prevented. Merely pressing the end portion of the outer case of the writing instrument allows a spring, a valve member and a flexible bellows portion of the ink tank to supply an appropriate amount of ink into the core.

  • Patent number: 3977797
    Abstract: The present invention provides a motor driven, helical screw conveyor having an impeller wheel at one end thereof. The screw conveyor is immersed in the liquid to be transferred and lifts the liquid so that the impeller may drive it through a first conduit and a first valve into a utilization device. The valve has three separate positions, the first of which permits delivery of a major portion of the fluid to the utilization device with a minor portion of the fluid being returned to the container via a second conduit. A second position of the first valve provides for flow of fluid from the container, through the first conduit, through the first valve and then directly back to the container via the second conduit.
